Pediatric News

SAVANNAH, GEORGIA — When Ann & Robert H. Lurie Children’s Hospital of Chicago pediatric neurologist Nancy L. Kuntz, MD, was a fellow about 45 years ago, there were few more devastating diagnoses than Duchenne muscular dystrophy (DMD).

“The rule of thumb was that they would stop walking by age 10 and probably die around age 20, and there was not much we could do,” Kuntz told colleagues at the American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM) 2024.

Now, the landscape of DMD therapy is transforming at a rapid pace. “In the last 8 years, we’ve seen eight different therapies that are FDA-approved specifically for Duchenne, and many more are in the pipeline,” said session moderator Kathryn Mosher, MD, a pediatric physical medicine and rehabilitation physician at Akron Children’s Hospital, Akron, Ohio.

This is both good news and a new challenge for clinicians: Which of these treatments are best for which patients? Kuntz said the traditional therapy of corticosteroids is still crucial. However, “there are still families begging to not use steroids, or refusing to use steroids, just not filling the prescriptions,” she said.
 

Beware of Parents Who Reject Steroids

The failure to use steroids “breaks your heart” because data show their impact on “really important functions like walking and being able to get up from the ground,” she said. “You can add months and years to life with this treatment.”

However, “while we have shown that using corticosteroids makes a difference, I don’t think that we’ve really worked out the best age at which to start the steroids, or the dosing schedule, or even the type of steroids,” she cautioned.

In an accompanying presentation about therapy for DMD, pediatric neurologist Craig M. Zaidman, MD, of Washington University in St. Louis, Missouri, cautioned that “daily steroids make a big impact on your growth and particularly on your height.”

In particular, the corticosteroid deflazacort has been linked to more cataracts than prednisone and less weight gain and height growth. “They really don’t grow, they don’t get taller, and they also don’t gain weight. They look like little boys when they’re 13 years old.”
 

Deflazacort or Vamorolone?

Vamorolone (Agamree) is a cheaper corticosteroid alternative to deflazacort (Emflaza), and a 2024 study showed no difference in functional outcomes over 48 weeks, he said. Also, daily vamorolone does a better job of preserving height growth than daily prednisone, he said, and he’s seen less risk for vertebral fractures.

Where do newer drugs fit in? One crucial thing to know about the new generation of targeted therapies is that they’re often mutation-dependent, Kuntz said. They may only work in patients with certain mutations, or mutations may lead to more side effects.

“You should have the exact mutation of your patient, and then you can look and see what they’re eligible for,” she said.

$700,000 a Year for Givinostat

Zaidman highlighted the newly approved givinostat (Duvyzat), a histone deacetylase inhibitor approved for boys 6 years or older. The cost is $700,000 a year, he said, and it’s been linked to less decline in four-stair climb per a double-blind, placebo-controlled, phase 3 trial.

The drug can cause side effects such as reducing platelets, boosting triglycerides, and inducing gastrointestinal problems. “When you drop the dose, these problems go away,” he said.

Does givinostat work? While trial data are challenging to interpret, they do suggest that patients “will lose skill, but they might not lose two or three skills they otherwise would have,” Zaidman said. “To me, that’s quite compelling.”

As for exon-skipping therapies, another new-generation option for DMD, he noted that “these drugs are on the market based on their accelerated approval. We will never have the perfect phase 3, randomized, controlled, long-term trial for these. It’s just not going to come. This is what we get.”

Mosher disclosed the advisory board (Sarepta Therapeutics, Pfizer, Reata Pharmaceuticals, and PTC). Kuntz disclosed advisory board (Astellas Pharma, Inc., argenx, Catalyst, Entrada Therapeutics, Genentech, and Novartis), exchange expert on-demand program (Sarepta Therapeutics), speaker (Genentech, Sarepta Therapeutics, and Solid), and research funding (Astellas Pharma, Inc., argenx, Biogen, Catalyst, Genentech, Novartis, and Sarepta Therapeutics).

TOPLINE:

An estimated 72 million ambulatory visits for superficial cutaneous fungal infections (SCFIs) in the United States were recorded during 2005-2016, with an increasing trend over the years. Tinea unguium, tinea pedis, and tinea corporis were among the most common infections.

METHODOLOGY:

• Researchers analyzed data from the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey from 2005 to 2016, to evaluate trends in the prevalence of SCFIs during this period.
• The analysis included over 13 billion ambulatory visits to nonfederally funded community, office-based physician practices, and emergency or outpatient departments in the United States, with an estimated 1,104,258,333 annual average.
• The Jonckheere-Terpstra nonparametric test for trend was used to determine the pattern of SCFI prevalence over the 12-year period.

TAKEAWAY:

• SCFIs constituted approximately 0.54% of all annual ambulatory visits, with an estimated 6,001,852 visits for SCFIs per year and over 72 million total visits for the infections during the study period.
• Tinea unguium, tinea pedis, and tinea corporis were the most common infections, comprising 20.5%, 12.2%, and 12.0% of the total visits, respectively.
• Researchers noted an increasing trend in annual SCFIs (P = .03).

IN PRACTICE:

“We observed a high burden of SCFIs among outpatient visits in the United States and an increasing trend in their prevalence,” the authors wrote. These results, they added, “highlight the importance of healthcare providers being able to identify, treat, and, when necessary, refer patients with SCFIs, as a high burden of disease is associated with a significant negative impact on the individual and population levels.”

SOURCE:

The study was co-led by Sarah L. Spaulding, BS, and A. Mitchel Wride, BA, from the Yale School of Medicine, New Haven, Connecticut, and was published online October 30 in the Journal of the American Academy of Dermatology.

LIMITATIONS:

The authors did not list any study limitations.

DISCLOSURES:

The lead authors were supported by Yale School of Medicine Medical Student Research Fellowships. Two other authors declared receiving consulting fees, research funding, and licensing fees outside the submitted work and also served on a data and safety monitoring board for Advarra Inc.

Irritable bowel syndrome (IBS) is one of the most common conditions encountered by both primary care providers and gastroenterologists, with a pooled global prevalence of 11.2%. This functional bowel disorder is characterized by abdominal pain or discomfort, diarrhea and/or constipation, and bloating.

Unfortunately, IBS is often misunderstood or minimized by some healthcare professionals, according to Alan Desmond, MB, consultant in gastroenterology and general internal medicine, Torbay Hospital, UK National Health Service.

Desmond regularly sees patients who either haven’t been accurately diagnosed or have been told, “Don’t worry, it’s ‘just’ irritable bowel syndrome,” he said at the recent International Conference on Nutrition in Medicine.

A 2017 study involving nearly 2000 patients with a history of gastrointestinal (GI) symptoms found that 43.1% of those who met the criteria for IBS were undiagnosed, and among those who were diagnosed, 26% were not receiving treatment.

“Many clinicians vastly underestimate the impact functional GI symptoms have on our patients in lack of productivity, becoming homebound or losing employment, the inability to enjoy a meal with friends or family, and always needing to know where the nearest bathroom is, for example,” Desmond said in an interview.

IBS can profoundly affect patients’ mental health. One study found that 38% of patients with IBS attending a tertiary care clinic contemplated suicide because they felt hopeless about ever achieving symptom relief.

Today, several dietary, pharmacologic, and psychological/behavioral approaches are available to treat patients with IBS, noted William D. Chey, MD, AGAF, chief of the Division of Gastroenterology and Hepatology, University of Michigan, Ann Arbor, Michigan.

“Each individual patient may need a different combination of these foundational treatments,” he said. “One size doesn’t fit all.”
 

Diagnostic Pathway

One reason IBS is so hard to diagnose is that it’s a “symptom-based disorder, with identification of the condition predicated upon certain key characteristics that are heterogeneous,” Chey said in an interview. “IBS in patient ‘A’ may not present the same way as IBS in patient ‘B,’ although there are certain foundational common characteristics.”

IBS involves “abnormalities in the motility and contractility of the GI tract,” he said. It can present with diarrhea (IBS-D), constipation (IBS-C), or a mixture or alternation of diarrhea and constipation (IBS-M).

Patients with IBS-D often have an exaggerated gastro-colonic response, while those with IBS-C often have a blunted response.

Beyond stool abnormalities and abdominal pain/discomfort, patients often report bloating/distension, low backache, lethargy, nausea, thigh pain, and urinary and gynecologic symptoms.

Historically, IBS has been regarded as a “diagnosis of exclusion” because classic diagnostic tests typically yield no concrete findings. Desmond noted that several blood tests, procedures, imaging studies, and other tests are available to rule out other organic GI conditions, as outlined in the Table.

 

If the patient comes from a geographical region where giardia is endemic, clinicians also should consider testing for the parasite, Chey said.
 

New Understanding of IBS Etiology

Now, advances in the understanding of IBS are changing the approach to the disease.

“The field is moving away from seeing IBS as a ‘wastebasket diagnosis,’ recognizing that there are other causes of a patient’s symptoms,” Mark Pimentel, MD, associate professor of medicine and gastroenterology, Cedars-Sinai, Los Angeles, said in an interview. “What’s made IBS so difficult to diagnose has been the absence of biological markers and hallmark findings on endoscopy.”

Recent research points to novel bacterial causes as culprits in the development of IBS. In particular, altered small bowel microbiota can be triggered by acute gastroenteritis.

Food poisoning can trigger the onset of IBS — a phenomenon called “postinfectious IBS (PI-IBS),” said Pimentel, who is also executive director of the Medically Associated Science and Technology Program at Cedars-Sinai. PI-IBS almost always takes the form of IBS-D, with up to 60% of patients with IBS-D suffering the long-term sequelae of food poisoning.

The types of bacteria most commonly associated with gastroenteritis are Shigella, Campylobacter, Salmonella, and Escherichia coli, Pimentel said. All of them release cytolethal distending toxin B (CdtB), causing the body to produce antibodies to the toxin.

CdtB resembles vinculin, a naturally occurring protein critical for healthy gut function. “Because of this molecular resemblance, the immune system often mistakes one for the other, producing anti-vinculin,” Pimentel explained.

This autoimmune response leads to disruptions in the gut microbiome, ultimately resulting in PI-IBS. The chain of events “doesn’t necessarily happen immediately,” Pimentel said. “You might have developed food poisoning at a party weeks or months ago.”

Acute gastroenteritis is common, affecting as many as 179 million people in the United States annually. A meta-analysis of 47 studies, incorporating 28,270 patients, found that those who had experienced acute gastroenteritis had a fourfold higher risk of developing IBS compared with nonexposed controls.

“The problem isn’t only the IBS itself, but the fact that people with PI-IBS are four times as likely to contract food poisoning again, which can further exacerbate IBS symptoms,” Pimentel said.

Diarrhea-predominant IBS can be detected through the presence of two blood biomarkers — anti-CdtB and anti-vinculin — in a blood test developed by Pimentel and his group.

“Elevation in either of these biomarkers establishes the diagnosis,” Pimentel said. “This is a breakthrough because it represents the first test that can make IBS a ‘diagnosis of inclusion.’”

The blood test also can identify IBS-M but not IBS-C.

Pimentel said that IBS-C is associated with increased levels of methanogenic archaea, which can be diagnosed by a positive methane breath test. “Methane gas slows intestinal contractility, which might result in constipation,” he said.
 

Diet as a Treatment Option

Diet is usually the starting point for IBS treatment, Chey said. “The standard dietary recommendations, as defined by the National Institute for Health and Care Excellence Guidance for managing IBS, are reasonable and common sense — eating three meals a day, avoiding carbonated beverages, excess alcohol, and excess caffeine, and avoiding hard-to-digest foods that can be gas producing.”

A diet low in fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPs), which are carbohydrates that aren’t completely absorbed in the intestines, has been shown to be effective in alleviating GI distress in as many as 86% of patients with IBS, leading to improvements in overall GI symptoms as well as individual symptoms (eg, abdominal pain, bloating, constipation, diarrhea, and flatulence).

Desmond recommends the low FODMAP program delineated by Monash University in Australia. The diet should be undertaken only under the supervision of a dietitian, he warned. Moreover, following it on a long-term basis can have an adverse impact on dietary quality and the gut microbiome. Therefore, “it’s important to embark on stepwise reintroduction of FODMAPS under supervision to find acceptable thresholds that don’t cause a return of symptoms.”

A growing body of research suggests that following the Mediterranean diet can be helpful in reducing IBS symptoms. Chey said that some patients who tend to over-restrict their eating might benefit from a less restrictive diet than the typical low FODMAPs diet. For them, the Mediterranean diet may be a good option.
 

Pharmacotherapy for IBS

Nutritional approaches aren’t for everyone, Chey noted. “Some people don’t want to be on a highly restricted diet.” For them, medications addressing symptoms might be a better option.

Antispasmodics — either anticholinergics (hyoscine and dicyclomine) or smooth muscle relaxants (alverine, mebeverine, and peppermint oil) — can be helpful, although they can worsen constipation in a dose-dependent manner. It is advisable to use them on an as-needed rather than long-term basis.

Antidiarrheal agents include loperamide and diphenoxylate.

For constipation, laxatives (eg, senna, bisacodyl, polyethylene glycol, and sodium picosulfate) can be helpful.

Desmond noted that the American Gastroenterological Association does not recommend routine use of probiotics for most GI disorders, including IBS. Exceptions include prevention of Clostridioides difficile, ulcerative colitis, and pouchitis.
 

Targeting the Gut-Brain Relationship

Stress plays a role in exacerbating symptoms in patients with IBS and is an important target for intervention.

“If patients are living with a level of stress that’s impairing, we won’t be able to solve their gut issues until we resolve their stress issues,” Desmond said. “We need to calm the gut-microbiome-brain axis, which is multidimensional and bidirectional.”

Many people — even those without IBS — experience queasiness or diarrhea prior to a major event they’re nervous about, Chey noted. These events activate the brain, which activates the nervous system, which interacts with the GI tract. Indeed, IBS is now recognized as a disorder of gut-brain interaction, he said.

“We now know that the microbiome in the GI tract influences cognition and emotional function, depression, and anxiety. One might say that the gut is the ‘center of the universe’ to human beings,” Chey said.

Evidence-based psychological approaches for stress reduction in patients with IBS include cognitive behavioral therapy, specifically tailored to helping the patient identify associations between IBS symptoms and thoughts, emotions, and actions, as well as learning new behaviors and engaging in stress management. Psychodynamic (interpersonal) therapy enables patients to understand the connection between GI symptoms and interpersonal conflicts, emotional factors, or relationship difficulties.

Gut-directed hypnotherapy (GDH) is a “proven modality for IBS,” Desmond said. Unlike other forms of hypnotherapy, GDH focuses specifically on controlling and normalizing GI function. Studies have shown a reduction of ≥ 30% in abdominal pain in two thirds of participants, with overall response rates up to 85%. It can be delivered in an individual or group setting or via a smartphone.

Desmond recommends mindfulness-based therapy (MBT) for IBS. MBT focuses on the “cultivation of mindfulness, defined as intentional, nonjudgmental, present-focused awareness.” It has been found effective in reducing flares and the markers of gut inflammation in ulcerative colitis, as well as reducing symptoms of IBS.

Chey noted that an emerging body of literature supports the potential role of acupuncture in treating IBS, and his clinic employs it. “I would like to see further research into other areas of CAM [complementary and alternative medicine], including herbal approaches to IBS symptoms as well as stress.”

Finally, all the experts agree that more research is needed.

“The real tragedy is that the NIH invests next to nothing in IBS, in contrast to inflammatory bowel disease and many other conditions,” Pimentel said. “Yet IBS is 45 times more common than inflammatory bowel disease.”

Pimentel hopes that with enough advocacy and recognition that IBS isn’t “just stress-related,” more resources will be devoted to understanding this debilitating condition.

A 2017 study involving nearly 2000 patients with a history of gastrointestinal (GI) symptoms found that 43.1% of those who met the criteria for IBS were undiagnosed, and among those who were diagnosed, 26% were not receiving treatment.

“Many clinicians vastly underestimate the impact functional GI symptoms have on our patients in lack of productivity, becoming homebound or losing employment, the inability to enjoy a meal with friends or family, and always needing to know where the nearest bathroom is, for example,” Desmond said in an interview.

IBS can profoundly affect patients’ mental health. One study found that 38% of patients with IBS attending a tertiary care clinic contemplated suicide because they felt hopeless about ever achieving symptom relief.

Today, several dietary, pharmacologic, and psychological/behavioral approaches are available to treat patients with IBS, noted William D. Chey, MD, AGAF, chief of the Division of Gastroenterology and Hepatology, University of Michigan, Ann Arbor, Michigan.

“Each individual patient may need a different combination of these foundational treatments,” he said. “One size doesn’t fit all.”
 

Diagnostic Pathway

One reason IBS is so hard to diagnose is that it’s a “symptom-based disorder, with identification of the condition predicated upon certain key characteristics that are heterogeneous,” Chey said in an interview. “IBS in patient ‘A’ may not present the same way as IBS in patient ‘B,’ although there are certain foundational common characteristics.”

IBS involves “abnormalities in the motility and contractility of the GI tract,” he said. It can present with diarrhea (IBS-D), constipation (IBS-C), or a mixture or alternation of diarrhea and constipation (IBS-M).

Patients with IBS-D often have an exaggerated gastro-colonic response, while those with IBS-C often have a blunted response.

Beyond stool abnormalities and abdominal pain/discomfort, patients often report bloating/distension, low backache, lethargy, nausea, thigh pain, and urinary and gynecologic symptoms.

Historically, IBS has been regarded as a “diagnosis of exclusion” because classic diagnostic tests typically yield no concrete findings. Desmond noted that several blood tests, procedures, imaging studies, and other tests are available to rule out other organic GI conditions, as outlined in the Table.

 

If the patient comes from a geographical region where giardia is endemic, clinicians also should consider testing for the parasite, Chey said.
 

New Understanding of IBS Etiology

Now, advances in the understanding of IBS are changing the approach to the disease.

“The field is moving away from seeing IBS as a ‘wastebasket diagnosis,’ recognizing that there are other causes of a patient’s symptoms,” Mark Pimentel, MD, associate professor of medicine and gastroenterology, Cedars-Sinai, Los Angeles, said in an interview. “What’s made IBS so difficult to diagnose has been the absence of biological markers and hallmark findings on endoscopy.”

Recent research points to novel bacterial causes as culprits in the development of IBS. In particular, altered small bowel microbiota can be triggered by acute gastroenteritis.

Food poisoning can trigger the onset of IBS — a phenomenon called “postinfectious IBS (PI-IBS),” said Pimentel, who is also executive director of the Medically Associated Science and Technology Program at Cedars-Sinai. PI-IBS almost always takes the form of IBS-D, with up to 60% of patients with IBS-D suffering the long-term sequelae of food poisoning.

The types of bacteria most commonly associated with gastroenteritis are Shigella, Campylobacter, Salmonella, and Escherichia coli, Pimentel said. All of them release cytolethal distending toxin B (CdtB), causing the body to produce antibodies to the toxin.

CdtB resembles vinculin, a naturally occurring protein critical for healthy gut function. “Because of this molecular resemblance, the immune system often mistakes one for the other, producing anti-vinculin,” Pimentel explained.

This autoimmune response leads to disruptions in the gut microbiome, ultimately resulting in PI-IBS. The chain of events “doesn’t necessarily happen immediately,” Pimentel said. “You might have developed food poisoning at a party weeks or months ago.”

Acute gastroenteritis is common, affecting as many as 179 million people in the United States annually. A meta-analysis of 47 studies, incorporating 28,270 patients, found that those who had experienced acute gastroenteritis had a fourfold higher risk of developing IBS compared with nonexposed controls.

“The problem isn’t only the IBS itself, but the fact that people with PI-IBS are four times as likely to contract food poisoning again, which can further exacerbate IBS symptoms,” Pimentel said.

Diarrhea-predominant IBS can be detected through the presence of two blood biomarkers — anti-CdtB and anti-vinculin — in a blood test developed by Pimentel and his group.

“Elevation in either of these biomarkers establishes the diagnosis,” Pimentel said. “This is a breakthrough because it represents the first test that can make IBS a ‘diagnosis of inclusion.’”

The blood test also can identify IBS-M but not IBS-C.

Pimentel said that IBS-C is associated with increased levels of methanogenic archaea, which can be diagnosed by a positive methane breath test. “Methane gas slows intestinal contractility, which might result in constipation,” he said.
 

Diet as a Treatment Option

Diet is usually the starting point for IBS treatment, Chey said. “The standard dietary recommendations, as defined by the National Institute for Health and Care Excellence Guidance for managing IBS, are reasonable and common sense — eating three meals a day, avoiding carbonated beverages, excess alcohol, and excess caffeine, and avoiding hard-to-digest foods that can be gas producing.”

A diet low in fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPs), which are carbohydrates that aren’t completely absorbed in the intestines, has been shown to be effective in alleviating GI distress in as many as 86% of patients with IBS, leading to improvements in overall GI symptoms as well as individual symptoms (eg, abdominal pain, bloating, constipation, diarrhea, and flatulence).

Desmond recommends the low FODMAP program delineated by Monash University in Australia. The diet should be undertaken only under the supervision of a dietitian, he warned. Moreover, following it on a long-term basis can have an adverse impact on dietary quality and the gut microbiome. Therefore, “it’s important to embark on stepwise reintroduction of FODMAPS under supervision to find acceptable thresholds that don’t cause a return of symptoms.”

A growing body of research suggests that following the Mediterranean diet can be helpful in reducing IBS symptoms. Chey said that some patients who tend to over-restrict their eating might benefit from a less restrictive diet than the typical low FODMAPs diet. For them, the Mediterranean diet may be a good option.
 

Pharmacotherapy for IBS

Nutritional approaches aren’t for everyone, Chey noted. “Some people don’t want to be on a highly restricted diet.” For them, medications addressing symptoms might be a better option.

Antispasmodics — either anticholinergics (hyoscine and dicyclomine) or smooth muscle relaxants (alverine, mebeverine, and peppermint oil) — can be helpful, although they can worsen constipation in a dose-dependent manner. It is advisable to use them on an as-needed rather than long-term basis.

Antidiarrheal agents include loperamide and diphenoxylate.

For constipation, laxatives (eg, senna, bisacodyl, polyethylene glycol, and sodium picosulfate) can be helpful.

Desmond noted that the American Gastroenterological Association does not recommend routine use of probiotics for most GI disorders, including IBS. Exceptions include prevention of Clostridioides difficile, ulcerative colitis, and pouchitis.
 

Targeting the Gut-Brain Relationship

Stress plays a role in exacerbating symptoms in patients with IBS and is an important target for intervention.

“If patients are living with a level of stress that’s impairing, we won’t be able to solve their gut issues until we resolve their stress issues,” Desmond said. “We need to calm the gut-microbiome-brain axis, which is multidimensional and bidirectional.”

Many people — even those without IBS — experience queasiness or diarrhea prior to a major event they’re nervous about, Chey noted. These events activate the brain, which activates the nervous system, which interacts with the GI tract. Indeed, IBS is now recognized as a disorder of gut-brain interaction, he said.

“We now know that the microbiome in the GI tract influences cognition and emotional function, depression, and anxiety. One might say that the gut is the ‘center of the universe’ to human beings,” Chey said.

Evidence-based psychological approaches for stress reduction in patients with IBS include cognitive behavioral therapy, specifically tailored to helping the patient identify associations between IBS symptoms and thoughts, emotions, and actions, as well as learning new behaviors and engaging in stress management. Psychodynamic (interpersonal) therapy enables patients to understand the connection between GI symptoms and interpersonal conflicts, emotional factors, or relationship difficulties.

Gut-directed hypnotherapy (GDH) is a “proven modality for IBS,” Desmond said. Unlike other forms of hypnotherapy, GDH focuses specifically on controlling and normalizing GI function. Studies have shown a reduction of ≥ 30% in abdominal pain in two thirds of participants, with overall response rates up to 85%. It can be delivered in an individual or group setting or via a smartphone.

Desmond recommends mindfulness-based therapy (MBT) for IBS. MBT focuses on the “cultivation of mindfulness, defined as intentional, nonjudgmental, present-focused awareness.” It has been found effective in reducing flares and the markers of gut inflammation in ulcerative colitis, as well as reducing symptoms of IBS.

Chey noted that an emerging body of literature supports the potential role of acupuncture in treating IBS, and his clinic employs it. “I would like to see further research into other areas of CAM [complementary and alternative medicine], including herbal approaches to IBS symptoms as well as stress.”

Finally, all the experts agree that more research is needed.

“The real tragedy is that the NIH invests next to nothing in IBS, in contrast to inflammatory bowel disease and many other conditions,” Pimentel said. “Yet IBS is 45 times more common than inflammatory bowel disease.”

Pimentel hopes that with enough advocacy and recognition that IBS isn’t “just stress-related,” more resources will be devoted to understanding this debilitating condition.

Irritable bowel syndrome (IBS) is one of the most common conditions encountered by both primary care providers and gastroenterologists, with a pooled global prevalence of 11.2%. This functional bowel disorder is characterized by abdominal pain or discomfort, diarrhea and/or constipation, and bloating.

Unfortunately, IBS is often misunderstood or minimized by some healthcare professionals, according to Alan Desmond, MB, consultant in gastroenterology and general internal medicine, Torbay Hospital, UK National Health Service.

Only 12% of the nurses providing patient care at hospitals and health clinics today are men. Although the percentage of nurses has increased — men made up just 2.7% of nurses in 1970 — nursing is still considered a “pink collar” profession, a female-dominated field.

“We’ve made strides over the last couple of decades, but [the number of men pursuing nursing careers] is leveling out,” said Jason Dunne, DNP, MSN, RN, chief academic officer at the Arizona College of Nursing, Phoenix. “There continues to be persistent gender stereotypes that [have] discouraged men from entering the profession.”

A nationwide nursing shortage has led to increased efforts to attract more men to the profession and ensure that men in nursing feel valued and supported and want to continue their careers long term.

“The nursing shortage is very real,” Dunne said. “We need to be highly focused on the shortage and look at opportunities to bring diversity into the profession, and one big way to solve it is bringing more men into nursing.”
 

Representation Matters

Colleges recognize the need to diversify their nursing student population and have turned their attention to increasing the number of men attending informational sessions and career days. Dunne believes, “There is a general lack of awareness of nursing as a career choice [for men].”

The Nursing Consortium of Florida hosts a “Day in the Life of a Nurse” program to introduce high school students to nursing careers, and the University of Virginia School of Nursing invites male nursing students to speak at educational events to promote workforce diversity.

“When I was growing up, the males wouldn’t have been included in those sessions,” said Melissa Gilbert Gomes, PhD, APRN, PMHNP-BC, FNAP, FAAN, associate dean for diversity, equity, and inclusion at the University of Virginia School of Nursing, Charlottesville, Virginia. “It was nice to see their interest and to have a male student there for them to ask questions and to help them see that this could be a place for them.”

Nursing schools have also engaged in other efforts to encourage more men to consider nursing careers, from highlighting male nurses in marketing materials and engaging with men at career fairs to updating course curriculum to include content on men’s health and connecting male nursing students with men in nursing faculty or clinical settings.

Focusing on nursing as a lucrative career choice could also attract more men to the profession. On average, male registered nurses (RNs) make $7300 per year more than their female counterparts due to the gender pay gap. The median wage for male RNs in acute care, cardiology, and perioperative specialties is $90,000 annually.

At the University of Virginia School of Nursing, which the American Association for Men in Nursing (AAMN) named “Best School for Men in Nursing” in 2023, 20% of nursing students are men.

The school has a Men Advancing Nursing club and is in the process of chartering a new AAMN chapter. The goal, according to Gomes, is to create an environment where male nursing students feel represented and supported.

“Valuing the perspective that men bring [to nursing] is important,” she said. “Coming together [and] having that camaraderie and intrinsic motivation to specifically speak to areas that impact men ... is important.”
 

Promoting Patient Care

Highlighting the diversity of career options within the nursing profession is also essential. RNs can pursue careers in specialties ranging from pediatrics, orthopedics, and occupational health to anesthesia, cardiology, and nephrology. The specialty with the highest number of male RNs tends to be acute care, which encompasses emergency/trauma and medical-surgical.

John Schmidt, DNP, MSN, BSN, faculty member and program lead for the acute care nurse practitioner program at Purdue Global School of Nursing, refers to these specialties as having a high excitement factor.

“Men gravitate to nursing to help people,” he said. “In critical care, there is instant gratification. You see patients get better. It’s the same in the [intensive care unit] and the emergency department. We take care of them and can see how we made a difference.”

When hospitals and health systems create environments that support men in nursing, patients also benefit. Research shows that patients often prefer nurses of the same gender, and a more diverse healthcare workforce has been linked to improved patient outcomes. Reducing gender inequities among nursing staff could also improve job satisfaction and retention rates for men in nursing.

“When you’re in a vulnerable space as a patient ... it’s important to know that your care provider understands you [and] having men as nurses is a part of that,” said Gomes. “Even though patients might not be used to having a male nurse at the bedside, once they have the experience, it challenges preconceived notions [and] that connection is important.”

Hospitals must proactively support men in nursing to achieve the benefits of greater gender diversity in the nursing workforce. Male nurses have fewer role models and report higher levels of loneliness, isolation, and role strain.

Groups such as NYC Men in Nursing and mentorship programs such as Men in Nursing at RUSH University College of Nursing and RUSH University Medical Center, and the North Carolina Healthcare Association Diverse Healthcare Leaders Mentorship Program were designed to provide coaching, education, and networking opportunities and connect men in nursing.

Male nurses, Dunne added, must be role models and must take the lead in changing the conversations about gender roles in nursing. Establishing support systems and mentorship opportunities is instrumental in inspiring men to pursue nursing careers and creating visibility into the profession and “would create a level of parity for men in the profession and encourage them to want to stay in nursing as a long-term career.”

He told this news organization that creating scholarships for men enrolled in nursing school, increasing the involvement of male nurse leaders in recruitment efforts, and updating curriculum to ensure men are reflected in the materials is also essential.

“We’ve got to be willing and open to having the conversations to end the stereotypes that have plagued the profession,” said Dunne. “And we’ve got to push men in nursing to be front and center so folks see that there are opportunities for men in nursing.”

Establishing support systems and mentorship opportunities is instrumental in inspiring men to pursue nursing careers and creating visibility into the profession and “would create a level of parity for men in the profession and encourage them to want to stay in nursing as a long-term career.”

He told this news organization that creating scholarships for men enrolled in nursing school, increasing the involvement of male nurse leaders in recruitment efforts, and updating curriculum to ensure men are reflected in the materials is also essential.

“We’ve got to be willing and open to having the conversations to end the stereotypes that have plagued the profession,” said Dunne. “And we’ve got to push men in nursing to be front and center so folks see that there are opportunities for men in nursing.”

Only 12% of the nurses providing patient care at hospitals and health clinics today are men. Although the percentage of nurses has increased — men made up just 2.7% of nurses in 1970 — nursing is still considered a “pink collar” profession, a female-dominated field.

“We’ve made strides over the last couple of decades, but [the number of men pursuing nursing careers] is leveling out,” said Jason Dunne, DNP, MSN, RN, chief academic officer at the Arizona College of Nursing, Phoenix. “There continues to be persistent gender stereotypes that [have] discouraged men from entering the profession.”

A nationwide nursing shortage has led to increased efforts to attract more men to the profession and ensure that men in nursing feel valued and supported and want to continue their careers long term.

“The nursing shortage is very real,” Dunne said. “We need to be highly focused on the shortage and look at opportunities to bring diversity into the profession, and one big way to solve it is bringing more men into nursing.”
 

Representation Matters

Colleges recognize the need to diversify their nursing student population and have turned their attention to increasing the number of men attending informational sessions and career days. Dunne believes, “There is a general lack of awareness of nursing as a career choice [for men].”

The Nursing Consortium of Florida hosts a “Day in the Life of a Nurse” program to introduce high school students to nursing careers, and the University of Virginia School of Nursing invites male nursing students to speak at educational events to promote workforce diversity.

“When I was growing up, the males wouldn’t have been included in those sessions,” said Melissa Gilbert Gomes, PhD, APRN, PMHNP-BC, FNAP, FAAN, associate dean for diversity, equity, and inclusion at the University of Virginia School of Nursing, Charlottesville, Virginia. “It was nice to see their interest and to have a male student there for them to ask questions and to help them see that this could be a place for them.”

Nursing schools have also engaged in other efforts to encourage more men to consider nursing careers, from highlighting male nurses in marketing materials and engaging with men at career fairs to updating course curriculum to include content on men’s health and connecting male nursing students with men in nursing faculty or clinical settings.

Focusing on nursing as a lucrative career choice could also attract more men to the profession. On average, male registered nurses (RNs) make $7300 per year more than their female counterparts due to the gender pay gap. The median wage for male RNs in acute care, cardiology, and perioperative specialties is $90,000 annually.

At the University of Virginia School of Nursing, which the American Association for Men in Nursing (AAMN) named “Best School for Men in Nursing” in 2023, 20% of nursing students are men.

The school has a Men Advancing Nursing club and is in the process of chartering a new AAMN chapter. The goal, according to Gomes, is to create an environment where male nursing students feel represented and supported.

“Valuing the perspective that men bring [to nursing] is important,” she said. “Coming together [and] having that camaraderie and intrinsic motivation to specifically speak to areas that impact men ... is important.”
 

Promoting Patient Care

Highlighting the diversity of career options within the nursing profession is also essential. RNs can pursue careers in specialties ranging from pediatrics, orthopedics, and occupational health to anesthesia, cardiology, and nephrology. The specialty with the highest number of male RNs tends to be acute care, which encompasses emergency/trauma and medical-surgical.

John Schmidt, DNP, MSN, BSN, faculty member and program lead for the acute care nurse practitioner program at Purdue Global School of Nursing, refers to these specialties as having a high excitement factor.

“Men gravitate to nursing to help people,” he said. “In critical care, there is instant gratification. You see patients get better. It’s the same in the [intensive care unit] and the emergency department. We take care of them and can see how we made a difference.”

When hospitals and health systems create environments that support men in nursing, patients also benefit. Research shows that patients often prefer nurses of the same gender, and a more diverse healthcare workforce has been linked to improved patient outcomes. Reducing gender inequities among nursing staff could also improve job satisfaction and retention rates for men in nursing.

“When you’re in a vulnerable space as a patient ... it’s important to know that your care provider understands you [and] having men as nurses is a part of that,” said Gomes. “Even though patients might not be used to having a male nurse at the bedside, once they have the experience, it challenges preconceived notions [and] that connection is important.”

Hospitals must proactively support men in nursing to achieve the benefits of greater gender diversity in the nursing workforce. Male nurses have fewer role models and report higher levels of loneliness, isolation, and role strain.

Groups such as NYC Men in Nursing and mentorship programs such as Men in Nursing at RUSH University College of Nursing and RUSH University Medical Center, and the North Carolina Healthcare Association Diverse Healthcare Leaders Mentorship Program were designed to provide coaching, education, and networking opportunities and connect men in nursing.

Federal lawmakers are rushing to soften the blow of Medicare’s 2025 effective pay cut for doctors in 2025, introducing a bill that could limit the cut. But they have little time to act.

In 2025, the conversion factor used to calculate payment to doctors and hospitals caring for Medicare patients will drop to $32.35, a nearly 3% decrease from the current level. 

Congress likely will act before the cuts take effect, said Rep. Larry Bucshon, MD (R-IN), who specialized in cardiothoracic surgery before joining Congress. Lawmakers in past years have typically tinkered with the Medicare physician fee schedule at the last minute, tucking in fixes to December legislative packages and spending bills. 

“I’m pretty optimistic that a good portion of the fee cuts will be mitigated and they won’t go through,” Bucshon told this news organization in an interview.

Bruce A. Scott, MD, president of the American Medical Association (AMA) said in a statement that CMS’ release of the final fee schedule on November 1 should trigger serious work on a change to the 2025 Medicare physician fee schedule.

“The fee schedule rule released [on November 1] starts the clock — with January 1 looming,” Scott said. “A legislative remedy will require hard work and compromise. The 66 million patients who rely on Medicare are counting on that.”

Both Bucshon and Scott also joined many lawmakers and medical associations in calling on Congress for a larger overhaul of the Medicare physician fee schedule, well beyond whatever temporary adjustment may be made in the months ahead to avoid or soften the 2025 cuts.

The physician fee schedule sets formulas and rules regarding how the largest US buyer of health services pays the almost 1.3 million clinicians who bill Medicare. Of these, 51% are physicians. The physician fee schedule also covers payments for nurse practitioners, physician assistants, physical therapists, and other health professionals.
 

Last Major Overhaul Unpopular

There’s broad dissatisfaction with Congress’ last major overhaul of the Medicare physician fee schedule. The 2015 Medicare Access and CHIP Reauthorization Act (MACRA) aimed to shift clinicians toward programs tying pay increases to quality measures. But the implementation of that aim through the Merit-based Incentive Payment System is widely considered a disappointment.

MACRA was intended to end the need for annual “doc fixes,” as Congress’ last-minute Medicare adjustments are known. Seventeen such tweaks passed before MACRA took effect. 

But MACRA did not include a broad-based inflation adjuster, and some clinicians’ incomes are lagging as inflation rates — and practice costs — have risen. Scott said the Medicare Economic Index, which is a measure used to gauge increases in practice costs for clinicians, is expected to rise by 3.5%.

“To put it bluntly, Medicare plans to pay us less while costs go up. You don’t have to be an economist to know that is an unsustainable trend, though one that has been going on for decades,” Scott said. “For physician practices operating on small margins already, this means it is harder to acquire new equipment, harder to retain staff, harder to take on new Medicare patients, and harder to keep the doors open, particularly in rural and underserved areas.”

In a statement, Jen Brull, MD, president of the American Academy of Family Physicians, noted that this likely will be the fifth year in a row that Congress will need to do a patch to prevent cuts in pay to clinicians. 

Bucshon, who will retire from the House in January, said he expects Congress to pass legislation tying Medicare payment rates to inflation — eventually.

“People want to find a way to fix this problem, but also do it in a way that does not cut benefits to anyone, and that’s the key,” Bucshon said. “We’re going to have to find a way to make sure that providers are properly reimbursed.”

Misinformation and outdated protocols contribute to the suboptimal management of anaphylaxis by patients and healthcare professionals, based on data from two new studies presented at the American College of Allergy, Asthma and Immunology Annual Scientific Meeting.

Anaphylaxis can strike suddenly, and many patients and caregivers at risk do not know which symptoms to treat with epinephrine, said Joni Chow, DO, of Baylor College of Medicine, San Antonio, Texas, in her presentation at the meeting.

“Early identification of anaphylaxis and early intervention with epinephrine are critical for improving patient outcomes,” Chow said in an interview.

“Many allergic reactions occur in community settings, where written action plans serve to instruct patients and caregivers on how to recognize and respond to these emergencies,” she said. “Currently, anaphylaxis action plans are developed based on the consensus of healthcare professionals, with limited information available on the preferences of patients and caregivers,” she noted. However, even with action plans, many patients and families struggle to recognize and manage severe allergic reactions effectively, she added.

In response to this issue, Chow and colleagues created a survey designed to assess the understanding of anaphylaxis recognition and management by patients and caregivers and to identify their preferences regarding the elements included in the action plans.

In the study, Chow and colleagues surveyed 96 patients and caregivers in an allergy clinic waiting room. The majority (95%) of the patients were prescribed epinephrine. Although 73% said they were comfortable identifying signs of anaphylaxis, only 14% said they were likely to use epinephrine as a first-line treatment.

The most common reason given for avoiding epinephrine was uncertainty over which symptoms to treat (40.6%), followed by hesitancy to visit an emergency department (24%), hesitancy to call 911 (17.7%), uncertainty about how to use epinephrine auto-injectors (11.5%), and fear of needles (5.2%).

Although 85% of the respondents understood that antihistamine use does not prevent the need for epinephrine in cases of anaphylactic reactions, 23.7% said they would use an antihistamine as the first treatment in these cases.

For patients with rash and wheezing after a suspected allergen exposure, approximately two thirds (64.5%) of the respondents said they would inject epinephrine and 10.8% would drive to the emergency room before taking any action, Chow said in her presentation.

The relatively low impact of fear of needles was unexpected, as fear of needles is considered a significant deterrent to epinephrine use, Chow told this news organization. “However, our respondents were more inclined to acknowledge a reluctance to escalate to emergency response as the major barrier to treatment,” she said.

The survey also asked patients what features of an anaphylaxis action plan would be most helpful. A majority of respondents (93%) rated a section for the management of mild (non-anaphylactic) allergic reaction symptoms as somewhat or very important. Visual aids for injection of epinephrine and visuals of anaphylaxis symptoms also ranked as somewhat or very important for 87.6% and 81% of respondents, respectively.

The study highlights the importance of educating allergy patients on recognizing and treating anaphylaxis and demonstrates that visuals were preferred in this survey population, Chow said. “Most patients and caregivers from our surveyed population report knowing how to treat anaphylaxis, but many would not use epinephrine as the first treatment,” she noted.

“The study focused on a single community clinic, and it would be beneficial to gather feedback from patients and caregivers representing a wider variety of educational, cultural, social, and socioeconomic backgrounds,” Chow told this news organization. “Additionally, input from other stakeholders, such as school nurses, would enhance knowledge,” she said.
 

Clinical Anaphylaxis Protocols Fall Short

A second study presented at the meeting showed the need to improve anaphylaxis education for clinicians.

Discrepancies in anaphylaxis management include variations in the definition and treatment of the condition, according to Carly Gunderson, DO, of Memorial Healthcare System, Pembroke Pines, Florida, who presented the study at the meeting.

“So often, we see patients in our office with a history of symptoms that meet criteria for anaphylaxis, yet when they call 911 and emergency medical services (EMS) arrive, they never receive epinephrine,” Gunderson said in an interview. “They receive antihistamines, steroids, everything except epinephrine, which is incredibly concerning given that epinephrine is always the first-line treatment for anaphylaxis,” she said.

“Because EMS providers are often the first healthcare professionals to assess patients experiencing anaphylaxis, their ability to recognize and appropriately treat anaphylaxis is essential,” Gunderson emphasized.

Gunderson and colleagues analyzed data from 30 states with mandatory Advanced Cardiac Life Support protocols to identify gaps in recognizing anaphylaxis and areas for improvement in prehospital management.

Only 15 states (50%) included gastrointestinal symptoms in the definition of anaphylaxis, 40% included neurologic manifestations, and 47% used a two-organ system definition, Gunderson noted in her presentation.

All 30 state protocols recommended diphenhydramine and epinephrine for anaphylactic reactions, 90% recommended albuterol if respiratory symptoms were present, 73% recommended intravenous fluids, and 60% recommended steroids. All but one of the state protocols listed epinephrine as the first-line recommendation for anaphylaxis; 25 states allowed epinephrine autoinjectors and 17 provided autoinjectors.

“We were shocked by how many protocols didn’t include gastrointestinal (abdominal pain, vomiting) or neurologic (lethargy, altered mental status) manifestations, when these are common presenting symptoms of anaphylaxis,” Gunderson told this news organization.

“We were also disappointed by how many protocols continue to recommend outdated interventions such as first-generation antihistamines and corticosteroids in the treatment of anaphylaxis,” she said.

Although anaphylaxis management has come a long way, the current study suggests that there is clearly room for improvement in the education of healthcare providers on how to identify and treat anaphylaxis, said Gunderson. “Most people think of anaphylaxis as the typical ‘face swelling up, throat closing’ type of reaction, which it can be, but in reality, there are so many other ways that it can present,” she said. “Healthcare providers must be aware of all of these possible manifestations so that we can treat in a timely manner to improve outcomes,” she added.

Limitations of the study included the focus only on states with mandatory or model EMS protocols, Gunderson told this news organization. As for additional research, the most important next steps are practical ones, namely, identifying ways to realistically implement necessary protocol changes, she said.
 

Real-World Data Support Need for Education

Real-world studies are important to identify current practice and opportunities for improvement, S. Shahzad Mustafa, MD, lead physician in allergy, immunology, and rheumatology at Rochester Regional Health and clinical associate professor of medicine at the University of Rochester School of Medicine and Dentistry, Rochester, New York, said in an interview.

“Management of anaphylaxis continues to evolve, and studies like these can help standardize evidence-based care across different medical settings, such as emergency medical services, urgent care, and emergency departments,” said Mustafa, who was not involved in either study.

The findings of the two studies were not unexpected, Mustafa said. “Heterogeneity in medical care is well recognized in numerous conditions, and anaphylaxis is no different. Patients and healthcare providers continue to have hesitation to use epinephrine and continue to overly rely on antihistamines and/or systemic steroids,” he noted.

For both studies, the takeaway message is that education is paramount to optimize anaphylaxis management, Mustafa told this news organization. “Education needs to focus on timely recognition of anaphylaxis, including atypical features such as gastrointestinal symptoms, and appropriate therapy with epinephrine,” he said.

Looking ahead, “research demonstrating differences in clinical outcomes with differing approaches to anaphylaxis may highlight the importance of early recognition and treatment with epinephrine,” said Mustafa. Management of anaphylaxis also lends itself to quality improvement studies, he added.

Neither of the studies received any outside funding. The researchers had no financial conflicts to disclose. Mustafa had no disclosures related to anaphylaxis but disclosed serving on the speakers’ bureau for Genentech, GSK, AstraZeneca, Regeneron/Sanofi, and CSL Behring and received grants from Takeda.

In the study, Chow and colleagues surveyed 96 patients and caregivers in an allergy clinic waiting room. The majority (95%) of the patients were prescribed epinephrine. Although 73% said they were comfortable identifying signs of anaphylaxis, only 14% said they were likely to use epinephrine as a first-line treatment.

The most common reason given for avoiding epinephrine was uncertainty over which symptoms to treat (40.6%), followed by hesitancy to visit an emergency department (24%), hesitancy to call 911 (17.7%), uncertainty about how to use epinephrine auto-injectors (11.5%), and fear of needles (5.2%).

Although 85% of the respondents understood that antihistamine use does not prevent the need for epinephrine in cases of anaphylactic reactions, 23.7% said they would use an antihistamine as the first treatment in these cases.

For patients with rash and wheezing after a suspected allergen exposure, approximately two thirds (64.5%) of the respondents said they would inject epinephrine and 10.8% would drive to the emergency room before taking any action, Chow said in her presentation.

The relatively low impact of fear of needles was unexpected, as fear of needles is considered a significant deterrent to epinephrine use, Chow told this news organization. “However, our respondents were more inclined to acknowledge a reluctance to escalate to emergency response as the major barrier to treatment,” she said.

The survey also asked patients what features of an anaphylaxis action plan would be most helpful. A majority of respondents (93%) rated a section for the management of mild (non-anaphylactic) allergic reaction symptoms as somewhat or very important. Visual aids for injection of epinephrine and visuals of anaphylaxis symptoms also ranked as somewhat or very important for 87.6% and 81% of respondents, respectively.

The study highlights the importance of educating allergy patients on recognizing and treating anaphylaxis and demonstrates that visuals were preferred in this survey population, Chow said. “Most patients and caregivers from our surveyed population report knowing how to treat anaphylaxis, but many would not use epinephrine as the first treatment,” she noted.

“The study focused on a single community clinic, and it would be beneficial to gather feedback from patients and caregivers representing a wider variety of educational, cultural, social, and socioeconomic backgrounds,” Chow told this news organization. “Additionally, input from other stakeholders, such as school nurses, would enhance knowledge,” she said.
 

Clinical Anaphylaxis Protocols Fall Short

A second study presented at the meeting showed the need to improve anaphylaxis education for clinicians.

Discrepancies in anaphylaxis management include variations in the definition and treatment of the condition, according to Carly Gunderson, DO, of Memorial Healthcare System, Pembroke Pines, Florida, who presented the study at the meeting.

“So often, we see patients in our office with a history of symptoms that meet criteria for anaphylaxis, yet when they call 911 and emergency medical services (EMS) arrive, they never receive epinephrine,” Gunderson said in an interview. “They receive antihistamines, steroids, everything except epinephrine, which is incredibly concerning given that epinephrine is always the first-line treatment for anaphylaxis,” she said.

“Because EMS providers are often the first healthcare professionals to assess patients experiencing anaphylaxis, their ability to recognize and appropriately treat anaphylaxis is essential,” Gunderson emphasized.

Gunderson and colleagues analyzed data from 30 states with mandatory Advanced Cardiac Life Support protocols to identify gaps in recognizing anaphylaxis and areas for improvement in prehospital management.

Only 15 states (50%) included gastrointestinal symptoms in the definition of anaphylaxis, 40% included neurologic manifestations, and 47% used a two-organ system definition, Gunderson noted in her presentation.

All 30 state protocols recommended diphenhydramine and epinephrine for anaphylactic reactions, 90% recommended albuterol if respiratory symptoms were present, 73% recommended intravenous fluids, and 60% recommended steroids. All but one of the state protocols listed epinephrine as the first-line recommendation for anaphylaxis; 25 states allowed epinephrine autoinjectors and 17 provided autoinjectors.

“We were shocked by how many protocols didn’t include gastrointestinal (abdominal pain, vomiting) or neurologic (lethargy, altered mental status) manifestations, when these are common presenting symptoms of anaphylaxis,” Gunderson told this news organization.

“We were also disappointed by how many protocols continue to recommend outdated interventions such as first-generation antihistamines and corticosteroids in the treatment of anaphylaxis,” she said.

Although anaphylaxis management has come a long way, the current study suggests that there is clearly room for improvement in the education of healthcare providers on how to identify and treat anaphylaxis, said Gunderson. “Most people think of anaphylaxis as the typical ‘face swelling up, throat closing’ type of reaction, which it can be, but in reality, there are so many other ways that it can present,” she said. “Healthcare providers must be aware of all of these possible manifestations so that we can treat in a timely manner to improve outcomes,” she added.

Limitations of the study included the focus only on states with mandatory or model EMS protocols, Gunderson told this news organization. As for additional research, the most important next steps are practical ones, namely, identifying ways to realistically implement necessary protocol changes, she said.
 

Real-World Data Support Need for Education

Real-world studies are important to identify current practice and opportunities for improvement, S. Shahzad Mustafa, MD, lead physician in allergy, immunology, and rheumatology at Rochester Regional Health and clinical associate professor of medicine at the University of Rochester School of Medicine and Dentistry, Rochester, New York, said in an interview.

“Management of anaphylaxis continues to evolve, and studies like these can help standardize evidence-based care across different medical settings, such as emergency medical services, urgent care, and emergency departments,” said Mustafa, who was not involved in either study.

The findings of the two studies were not unexpected, Mustafa said. “Heterogeneity in medical care is well recognized in numerous conditions, and anaphylaxis is no different. Patients and healthcare providers continue to have hesitation to use epinephrine and continue to overly rely on antihistamines and/or systemic steroids,” he noted.

For both studies, the takeaway message is that education is paramount to optimize anaphylaxis management, Mustafa told this news organization. “Education needs to focus on timely recognition of anaphylaxis, including atypical features such as gastrointestinal symptoms, and appropriate therapy with epinephrine,” he said.

Looking ahead, “research demonstrating differences in clinical outcomes with differing approaches to anaphylaxis may highlight the importance of early recognition and treatment with epinephrine,” said Mustafa. Management of anaphylaxis also lends itself to quality improvement studies, he added.

Neither of the studies received any outside funding. The researchers had no financial conflicts to disclose. Mustafa had no disclosures related to anaphylaxis but disclosed serving on the speakers’ bureau for Genentech, GSK, AstraZeneca, Regeneron/Sanofi, and CSL Behring and received grants from Takeda.

Vaccination against human papilloma virus (HPV), a group of more than 200 viruses infecting at least 50% of sexually active people over their lifetimes, has proved more than 90% effective for preventing several diseases caused by high-risk HPV types. 

Gardasil 4: 2006 

It started in 2006 with the approval of Human Papillomavirus Quadrivalent, types 6, 11, 16, and 18 (Gardasil 4). Merck’s vaccine began to lower rates of cervical cancer, a major global killer of women.

“It’s fair to say the vaccine has been an American and a global public health success story in reducing rates of cervical cancer,” Paula M. Cuccaro, PhD, assistant professor of health promotion and behavioral sciences at University of Texas School of Public Health, Houston, said in an interview.

How does a common virus trigger such a lethal gynecologic malignancy? “It knocks out two important cancer suppressor genes in cells,” explained Christina Annunziata,MD, PhD, a medical oncologist and senior vice president of extramural discovery science for the American Cancer Society. HPV oncoproteins are encoded by the E6 and E7 genes. As in other DNA tumor viruses, the E6 and E7 proteins functionally inactivate the tumor suppressor proteins p53 and pRB, respectively.
 

US Prevalence

Despite screening and vaccination, cervical cancer is still very much around. This year, 13,820 new cases of invasive cervical cancer will be diagnosed in the United States, and approximately 4360 women will die of it, according to the American Cancer Society. Even before the advent of Gardasil 4, incidence rates had already decreased by more than half from the mid-1970s to the mid-2000s, thanks largely to Pap smear screening programs for treatable premalignant lesions. “The US rate had dropped to about 20 per 100,000 women even before Gardasil 4,” said Annunziata. “After the introduction of the first vaccine, it decreased to 7 per 100,000, a decrease of about 30%, but it remains plateaued now at about the same level.”

Although the past decade has seen rates generally stabilize, there have been some changes in different age groups. In women ages 30-44, rates increased 1.7% each year from 2012 to 2019, while rates declined 11% each year for women ages 20-24— probably reflecting the impact of the first wave of prevention from Gardasil 4.

In one 2021 population-based study of US cancer registry data from 1999 to 2017, rates of both cervical squamous cell carcinoma and adenocarcinoma dropped. The largest declines occurred in females 15-20 years old, the age group most likely to be vaccinated against HPV but not typically screened, suggesting a vaccine-related effect.
 

Gardasil 9: 2014

With the 2014 approval of the vaccine’s second iteration, Gardasil 9, which replaced Gardasil 4 and targeted 9 HPV strains, immunization has taken broader aim. The strains covered by Gardasil 9 protect against oropharyngeal and other head and neck cancers — as well as penile, anal, vulvar, and vaginal malignancies and premalignancies, and genital warts in both sexes ages 9-45. 

It may be years, however, before the impact of the newer polyvalent formulation is felt. “While the first vaccine has been successful against the prevalent strains of HPV linked to cervical cancer, it’s a little early to call it for the newer vaccine since oropharyngeal cancers tend to develop later in older men,” Cuccaro said. “But the types of HPV linked to mouth and throat cancers and covered by the newer vaccines are much less prevalent in those who are vaccinated. The strains not covered in the vaccine you see are equally present in the vaccinated and non-vaccinated.”

Angela L. Myers, MD, MPH, division director of infectious diseases and medical director of the Center for Wellbeing at Children’s Mercy in Kansas City, Missouri, added, “Unlike for cervical cancer, there are no screening programs for oropharyngeal lesions, so you have to wait to see rates until actual cancer develops.”

A 2023 review reported that HPV vaccination reduced levels of oropharyngeal HPV positivity in men, strengthening the case for pangender immunization. 

And in a recent phase 3 doubled-blind trial, GARDASIL 9 reduced the incidence of anogenital persistent infection caused by nine types of HPV compared with a placebo. 
 

Increasing Uptake

The current public health aim is to have 80% of young people in the targeted age group vaccinated with two doses. Today, uptake among those 9-26 years old stands at about 78% of girls and 75% of boys for the first dose, said Annunziata. “But it’s only about 61% for the two doses in the current series, and we want to improve that.” 

Some parents may still harbor fears that immunizing teens and tweens — both the American Academy of Pediatrics and the American Cancer Society recommend immunization at age 9 — will open the door to precocious sexual activity. 

“But overall, uptake in tweens and young teens has increased because the messaging has changed,” said Myers, with the rationale now focusing on cancer prevention not sexual-infection prophylaxis. “This is similar to the hepatitis B vaccine, which used to be given to young adults and is now given to newborns to prevent cancer.” 

Cuccaro added that a proactive presentation by healthcare professionals has a significant effect on vaccine uptake and increases the odds of vaccination ninefold. “Providers should take a presumptive approach and avoid just offering the vaccine as an option. It should be included with regular childhood vaccinations,” she said. “And the advantage of starting early at age 9 is that you can spread the doses out across other regular childhood vaccinations, whereas if you start at age 11, you need to add the HPV vaccine to three other vaccines that are given at that time.” 

After age 15, three doses are necessary. “Providers should stress to parents that it’s most effective when given before young people become sexually active and exposed to HPV,” Cuccaro said. And Myers stressed that despite the vaccine’s effectiveness, routine screening for cervical premalignancies is still important. 

Despite increasing coverage, vaccination rates have some distance to go before the public health target of at least 80% uptake of the series in the targeted age group, Cuccaro cautioned.

On the global stage, barriers to immunization remain, but the World Health Organization has endorsed a campaign to eradicate cervical cancer through HPV vaccination. It has predicted that the 21st century may be the last to experience HPV-associated cancers, currently responsible for more than 300,000 annual deaths worldwide.

Cannabis use may lead to thinning of the cerebral cortex in adolescents, research in mice and humans suggested.

The multilevel study demonstrated that tetrahydrocannabinol (THC), an active substance in cannabis, causes shrinkage of dendritic arborization — the neurons’ network of antennae that play a critical role in communication between brain cells.

The connection between dendritic arborization and cortical thickness was hinted at in an earlier study by Tomáš Paus, MD, PhD, professor of psychiatry and addictology at the University of Montreal, Quebec, Canada, and colleagues, who found that cannabis use in early adolescence was associated with lower cortical thickness in boys with a high genetic risk for schizophrenia.

“We speculated at that time that the differences in cortical thickness might be related to differences in dendritic arborization, and our current study confirmed it,” Paus said.

That confirmation came in the mouse part of the study, when coauthor Graciela Piñeyro, MD, PhD, also of the University of Montreal, counted the dendritic branches of mice exposed to THC and compared the total with the number of dendritic branches in unexposed mice. “What surprised me was finding that THC in the mice was targeting the same type of cells and structures that Dr. Paus had predicted would be affected from the human studies,” she said. “Structurally, they were mostly the neurons that contribute to synapses in the cortex, and their branching was reduced.”

Paus explained that in humans, a decrease in input from the affected dendrites “makes it harder for the brain to learn new things, interact with people, cope with new situations, et cetera. In other words, it makes the brain more vulnerable to everything that can happen in a young person’s life.”

Of Mice, Men, and Cannabis

Although associations between cannabis use by teenagers and variations in brain maturation have been well studied, the cellular and molecular underpinnings of these associations were unclear, according to the authors.

To investigate further, they conducted this three-step study. First, they exposed adolescent male mice to THC or a synthetic cannabinoid (WIN 55,212-2) and assessed differentially expressed genes, spine numbers, and the extent of dendritic complexity in the frontal cortex of each mouse.

Next, using MRI, they examined differences in cortical thickness in 34 brain regions in 140 male adolescents who experimented with cannabis before age 16 years and 327 who did not.

Then, they again conducted experiments in mice and found that 13 THC-related genes correlated with variations in cortical thickness. Virtual histology revealed that these 13 genes were coexpressed with cell markers of astrocytes, microglia, and a type of pyramidal cell enriched in genes that regulate dendritic expression.

Similarly, the WIN-related genes correlated with differences in cortical thickness and showed coexpression patterns with the same three cell types.

Furthermore, the affected genes were also found in humans, particularly in the thinner cortical regions of the adolescents who experimented with cannabis.

By acting on microglia, THC seems to promote the removal of synapses and, eventually, the reduction of the dendritic tree in mice, Piñeyro explained. That’s important not only because a similar mechanism may be at work in humans but also because “we now might have a model to test different types of cannabis products to see which ones are producing the greatest effect on neurons and therefore greater removal of synapses through the microglia. This could be a way of testing drugs that are out in the street to see which would be the most or least dangerous to the synapses in the brain.”
 

‘Significant Implications’

Commenting on the study, Yasmin Hurd, PhD, Ward-Coleman chair of translational neuroscience at the Icahn School of Medicine at Mount Sinai and director of the Addiction Institute of Mount Sinai in New York City, said, “These findings are in line with previous results, so they are feasible. This study adds more depth by showing that cortical genes that were differentially altered by adolescent THC correlated with cannabis-related changes in cortical thickness based on human neuroimaging data.” Hurd did not participate in the research.

“The results emphasize that consumption of potent cannabis products during adolescence can impact cortical function, which has significant implications for decision-making and risky behavior as well. It also can increase vulnerability to psychiatric disorders such as schizophrenia.”

Although a mouse model is “not truly the same as the human condition, the fact that the animal model also showed evidence of the morphological changes indicative of reduced cortical thickness, [like] the humans, is strong,” she said.

Additional research could include women and assess potential sex differences, she added.

Ronald Ellis, MD, PhD, an investigator in the Center for Medicinal Cannabis Research at the University of California, San Diego School of Medicine, said, “The findings are plausible and extend prior work showing evidence of increased risk for psychotic disorders later in life in adolescents who use cannabis.” Ellis did not participate in the research.

“Future studies should explore how these findings might vary across different demographic groups, which could provide a more inclusive understanding of how cannabis impacts the brain,” he said. “Additionally, longitudinal studies to track changes in the brain over time could help to establish causal relationships more robustly.

“The take-home message to clinicians at this point is to discuss cannabis use history carefully and confidentially with adolescent patients to better provide advice on its potential risks,” he concluded.

Paus added that he would tell patients, “If you’re going to use cannabis, don’t start early. If you have to, then do so in moderation. And if you have family history of mental illness, be very careful.”

No funding for the study was reported. Paus, Piñeyro, Hurd, and Ellis declared having no relevant financial relationships.

Cannabis use may lead to thinning of the cerebral cortex in adolescents, research in mice and humans suggested.

The multilevel study demonstrated that tetrahydrocannabinol (THC), an active substance in cannabis, causes shrinkage of dendritic arborization — the neurons’ network of antennae that play a critical role in communication between brain cells.

The connection between dendritic arborization and cortical thickness was hinted at in an earlier study by Tomáš Paus, MD, PhD, professor of psychiatry and addictology at the University of Montreal, Quebec, Canada, and colleagues, who found that cannabis use in early adolescence was associated with lower cortical thickness in boys with a high genetic risk for schizophrenia.

“We speculated at that time that the differences in cortical thickness might be related to differences in dendritic arborization, and our current study confirmed it,” Paus said.

That confirmation came in the mouse part of the study, when coauthor Graciela Piñeyro, MD, PhD, also of the University of Montreal, counted the dendritic branches of mice exposed to THC and compared the total with the number of dendritic branches in unexposed mice. “What surprised me was finding that THC in the mice was targeting the same type of cells and structures that Dr. Paus had predicted would be affected from the human studies,” she said. “Structurally, they were mostly the neurons that contribute to synapses in the cortex, and their branching was reduced.”

Paus explained that in humans, a decrease in input from the affected dendrites “makes it harder for the brain to learn new things, interact with people, cope with new situations, et cetera. In other words, it makes the brain more vulnerable to everything that can happen in a young person’s life.”

A growing body of research suggests that clinicians can offer chimeric antigen receptor (CAR) T-cell therapy safely and effectively on an outpatient basis — a positive development as clinicians strive to expand access beyond metropolitan areas.

In one recent study, an industry-funded phase 2 trial, researchers found similar outcomes from outpatient and inpatient CAR T-cell therapy for relapsed/refractory large B-cell lymphoma with lisocabtagene maraleucel (Breyanzi). 

Another recent study reported that outpatient treatment of B cell non-Hodgkin lymphoma with tisagenlecleucel (Kymriah) had similar efficacy to inpatient treatment. Meanwhile, a 2023 review of CAR T-cell therapy in various settings found similar outcomes in outpatient and inpatient treatment. 

“The future of CAR T-cell therapy lies in balancing safety with accessibility,” said Rayne Rouce, MD, a pediatric oncologist at Texas Children’s Cancer Center in Houston, Texas, in an interview. “Expanding CAR T-cell therapy beyond large medical centers is a critical next step.” 
 

Great Outcomes, Low Access

Since 2017, the FDA has approved six CAR T-cell therapies, which target cancer by harnessing the power of a patient’s own T cells. As an Oregon Health & Sciences University/Knight Cancer Center website explains, T cells are removed from the patient’s body, “genetically modified to make the chimeric antigen receptor, or CAR, [which] protein binds to specific proteins on the surface of cancer cells.”

Modified cells are grown and then infused back into the body, where they “multiply and may be able to destroy all the cancer cells.”

As Rouce puts it, “CAR T-cells have revolutionized the treatment of relapsed or refractory blood cancers.” One or more of the therapies have been approved to treat types of lymphoblastic leukemia, B-cell lymphoma, follicular lymphoma, mantle cell lymphoma, and multiple myeloma.

A 2023 review of clinical trial data reported complete response rates of 40%-54% in aggressive B-cell lymphoma, 67% in mantle cell lymphoma, and 69%-74% in indolent B cell lymphoma.

“Commercialization of CAR T-cell therapy brought hope that access would expand beyond the major academic medical centers with the highly specialized infrastructure and advanced laboratories required to manufacture and ultimately treat patients,” Rouce said. “However, it quickly became clear that patients who are underinsured or uninsured — or who live outside the network of the well-resourced institutions that house these therapies — are still unable to access these potentially life-saving therapies.”

A 2024 report estimated the cost of CAR T-cell therapy as $700,000-$1 million and said only a small percentage of those who could benefit from the treatment actually get it. For example, an estimated 10,000 patients with diffuse large B-cell lymphoma alone could benefit from CAR T therapy annually, but a survey of 200 US healthcare centers in 2021 found that 1900 procedures were performed overall for all indications. 
 

Distance to Treatment Is a Major Obstacle

Even if patients have insurance plans willing to cover CAR T-cell therapy, they may not be able get care. While more than 150 US centers are certified to administer the therapy, “distance to major medical centers with CAR T capabilities is a major obstacle,” Yuliya Linhares, MD, chief of lymphoma at Miami Cancer Institute in Miami, Florida, said in an interview. 

“I have had patients who chose to not proceed with CAR T therapy due to inability to travel the distance to the medical center for pre-CAR T appointments and assessments and a lack of caretakers who are available to stay nearby,” Linhares said.

Indeed, the challenges facing patients in rural and underserved urban areas can be overwhelming, Hoda Badr, PhD, professor of medicine at Baylor College of Medicine in Houston, Texas, said in an interview.

“They must take time off work, arrange accommodations near treatment sites, and manage travel costs, all of which strain limited financial resources. The inability to afford these additional expenses can lead to delays in receiving care or patients forgoing the treatment altogether,” Badr said. She added that “the psychological and social burden of being away from family and community support systems during treatment can intensify the stress of an already difficult situation.”

A statistic tells the story of the urban/community divide. CAR T-cell therapy administration at academic centers after leukapheresis — the separation and collection of white blood cells — is reported to be at around 90%, while it’s only 47% in community-based practices that have to refer patients elsewhere, Linhares noted. 
 

Researchers Explore CAR T-Cell Therapy in the Community 

Linhares is lead author of the phase 2 trial that explored administration of lisocabtagene maraleucel in 82 patients with relapsed/refractory large B-cell lymphoma. The findings were published Sept. 30 in Blood Advances.

The OUTREACH trial, funded by Juno/Bristol-Myers Squibb, treated patients in the third line and beyond at community medical centers (outpatient-monitored, 70%; inpatient-monitored, 30%). The trial didn’t require facilities to be certified by the Foundation for the Accreditation of Cellular Therapy (FACT); all had to be non-tertiary cancer centers that weren’t associated with a university. In order to administer therapy on the outpatient basis, the centers had to have phase 1 or hematopoietic stem cell transplant capabilities.

As Linhares explained, 72% of participating centers hadn’t provided CAR T-cell therapy before, and 44% did not have FACT accreditation. “About 32% of patients received CAR T at CAR T naive sites, while 70% of patients received CAR T as outpatients. Investigators had to decide whether patients qualified for the outpatient observation or had to be admitted for the inpatient observation,” she noted.
 

Community Outcomes Were Comparable to Major Trial

As for the results, grade 3 or higher adverse events occurred at a similar frequency among outpatients and inpatients at 74% and 76%, Linhares said. There were no grade 5 adverse events, and 25% of patients treated as outpatients were never hospitalized. 

Response rates were similar to those in the major TRANSCEND trial with the objective response rates rate of 80% and complete response rates of 54%.

“Overall,” Linhares said, “our study demonstrated that with the availability of standard operating procedures, specially trained staff and a multidisciplinary team trained in CAR T toxicity management, inpatient and outpatient CAR T administration is feasible at specialized community medical centers.”

In 2023, another study examined patients with B-cell non-Hodgkin lymphoma who were treated on an outpatient basis with tisagenlecleucel. Researchers reported that outpatient therapy was “feasible and associated with similar efficacy outcomes as inpatient treatment.”

And a 2023 systematic literature review identified 11 studies that reported outpatient vs inpatient outcomes in CAR T-cell therapy and found “comparable response rates (80-82% in outpatient and 72-80% in inpatient).” Costs were cheaper in the outpatient setting. 

Research findings like these are good news, Baylor College of Medicine’s Badr said. “Outpatient administration could help to scale the availability of this therapy to a broader range of healthcare settings, including those serving underserved populations. Findings indicate promising safety profiles, which is encouraging for expanding access.”
 

Not Every Patient Can Tolerate Outpatient Care

Linhares noted that the patients who received outpatient care in the lisocabtagene maraleucel study were in better shape than those in the inpatient group. Those selected for inpatient care had “higher disease risk characteristics, including high grade B cell lymphoma histology, higher disease burden, and having received bridging therapy. This points to the fact that the investigators properly selected patients who were at a higher risk of complications for inpatient observation. Additionally, some patients stayed as inpatient due to social factors, which increases length of stay independently of disease characteristics.”

Specifically, reasons for inpatient monitoring were disease characteristics (48%) including tumor burden and risk of adverse events; psychosocial factors (32%) including lack of caregiver support or transportation; COVID-19 precautions (8%); pre-infusion adverse events (8%) of fever and vasovagal reaction; and principal investigator decision (4%) due to limited hospital experience with CAR T-cell therapy.

Texas Children’s Cancer Center’s Rouce said “certain patients, particularly those with higher risk for complications or those who require intensive monitoring, may not be suited for outpatient CAR T-cell therapy. This may be due to other comorbidities or baseline factors known to predispose to CAR T-related toxicities. However, evidence-based risk mitigation algorithms may still allow closely monitored outpatient treatment, with recognition that hospital admission for incipient side effects may be necessary.”
 

What’s Next for Access to Therapy?

Rouce noted that her institution, like many others, is offering CAR T-cell therapy on an outpatient basis. “Additionally, continued scientific innovation, such as immediately available, off-the-shelf cell therapies and inducible safety switches, will ultimately improve access,” she said. 

Linhares noted a recent advance and highlighted research that’s now in progress. “CAR Ts now have an indication as a second-line therapy in relapsed/refractory large B-cell lymphoma, and there are ongoing clinical trials that will potentially move CAR Ts into the first line,” she said. “Some trials are exploring allogeneic, readily available off-the-shelf CAR T for the treatment of minimal residual disease positive large B-cell lymphoma after completion of first-line therapy.”

These potential advances “are increasing the need for CAR T-capable medical centers,” Linhares noted. “More and more medical centers with expert hematology teams are becoming CAR T-certified, with more patients having access to CAR T.”

Still, she said, “I don’t think access is nearly as good as it should be. Many patients in rural areas are still unable to get this life-saving treatment. “However, “it is very possible that other novel targeted therapies, such as bispecific antibodies, will be used in place of CAR T in areas with poor CAR T access. Bispecific antibody efficacy in various B cell lymphoma histologies are being currently explored.”

Rouce discloses relationships with Novartis and Pfizer. Linhares reports ties with Kyowa Kirin, AbbVie, ADC, BeiGene, Genentech, Gilead, GlaxoSmithKline, Seagen, and TG. Badr has no disclosures.

A growing body of research suggests that clinicians can offer chimeric antigen receptor (CAR) T-cell therapy safely and effectively on an outpatient basis — a positive development as clinicians strive to expand access beyond metropolitan areas.

In one recent study, an industry-funded phase 2 trial, researchers found similar outcomes from outpatient and inpatient CAR T-cell therapy for relapsed/refractory large B-cell lymphoma with lisocabtagene maraleucel (Breyanzi). 

Another recent study reported that outpatient treatment of B cell non-Hodgkin lymphoma with tisagenlecleucel (Kymriah) had similar efficacy to inpatient treatment. Meanwhile, a 2023 review of CAR T-cell therapy in various settings found similar outcomes in outpatient and inpatient treatment. 

“The future of CAR T-cell therapy lies in balancing safety with accessibility,” said Rayne Rouce, MD, a pediatric oncologist at Texas Children’s Cancer Center in Houston, Texas, in an interview. “Expanding CAR T-cell therapy beyond large medical centers is a critical next step.” 
 

Great Outcomes, Low Access

Since 2017, the FDA has approved six CAR T-cell therapies, which target cancer by harnessing the power of a patient’s own T cells. As an Oregon Health & Sciences University/Knight Cancer Center website explains, T cells are removed from the patient’s body, “genetically modified to make the chimeric antigen receptor, or CAR, [which] protein binds to specific proteins on the surface of cancer cells.”

Modified cells are grown and then infused back into the body, where they “multiply and may be able to destroy all the cancer cells.”

As Rouce puts it, “CAR T-cells have revolutionized the treatment of relapsed or refractory blood cancers.” One or more of the therapies have been approved to treat types of lymphoblastic leukemia, B-cell lymphoma, follicular lymphoma, mantle cell lymphoma, and multiple myeloma.

A 2023 review of clinical trial data reported complete response rates of 40%-54% in aggressive B-cell lymphoma, 67% in mantle cell lymphoma, and 69%-74% in indolent B cell lymphoma.

“Commercialization of CAR T-cell therapy brought hope that access would expand beyond the major academic medical centers with the highly specialized infrastructure and advanced laboratories required to manufacture and ultimately treat patients,” Rouce said. “However, it quickly became clear that patients who are underinsured or uninsured — or who live outside the network of the well-resourced institutions that house these therapies — are still unable to access these potentially life-saving therapies.”

A 2024 report estimated the cost of CAR T-cell therapy as $700,000-$1 million and said only a small percentage of those who could benefit from the treatment actually get it. For example, an estimated 10,000 patients with diffuse large B-cell lymphoma alone could benefit from CAR T therapy annually, but a survey of 200 US healthcare centers in 2021 found that 1900 procedures were performed overall for all indications. 
 

Distance to Treatment Is a Major Obstacle

Even if patients have insurance plans willing to cover CAR T-cell therapy, they may not be able get care. While more than 150 US centers are certified to administer the therapy, “distance to major medical centers with CAR T capabilities is a major obstacle,” Yuliya Linhares, MD, chief of lymphoma at Miami Cancer Institute in Miami, Florida, said in an interview. 

“I have had patients who chose to not proceed with CAR T therapy due to inability to travel the distance to the medical center for pre-CAR T appointments and assessments and a lack of caretakers who are available to stay nearby,” Linhares said.

Indeed, the challenges facing patients in rural and underserved urban areas can be overwhelming, Hoda Badr, PhD, professor of medicine at Baylor College of Medicine in Houston, Texas, said in an interview.

“They must take time off work, arrange accommodations near treatment sites, and manage travel costs, all of which strain limited financial resources. The inability to afford these additional expenses can lead to delays in receiving care or patients forgoing the treatment altogether,” Badr said. She added that “the psychological and social burden of being away from family and community support systems during treatment can intensify the stress of an already difficult situation.”

A statistic tells the story of the urban/community divide. CAR T-cell therapy administration at academic centers after leukapheresis — the separation and collection of white blood cells — is reported to be at around 90%, while it’s only 47% in community-based practices that have to refer patients elsewhere, Linhares noted. 
 

Researchers Explore CAR T-Cell Therapy in the Community 

Linhares is lead author of the phase 2 trial that explored administration of lisocabtagene maraleucel in 82 patients with relapsed/refractory large B-cell lymphoma. The findings were published Sept. 30 in Blood Advances.

The OUTREACH trial, funded by Juno/Bristol-Myers Squibb, treated patients in the third line and beyond at community medical centers (outpatient-monitored, 70%; inpatient-monitored, 30%). The trial didn’t require facilities to be certified by the Foundation for the Accreditation of Cellular Therapy (FACT); all had to be non-tertiary cancer centers that weren’t associated with a university. In order to administer therapy on the outpatient basis, the centers had to have phase 1 or hematopoietic stem cell transplant capabilities.

As Linhares explained, 72% of participating centers hadn’t provided CAR T-cell therapy before, and 44% did not have FACT accreditation. “About 32% of patients received CAR T at CAR T naive sites, while 70% of patients received CAR T as outpatients. Investigators had to decide whether patients qualified for the outpatient observation or had to be admitted for the inpatient observation,” she noted.
 

Community Outcomes Were Comparable to Major Trial

As for the results, grade 3 or higher adverse events occurred at a similar frequency among outpatients and inpatients at 74% and 76%, Linhares said. There were no grade 5 adverse events, and 25% of patients treated as outpatients were never hospitalized. 

Response rates were similar to those in the major TRANSCEND trial with the objective response rates rate of 80% and complete response rates of 54%.

“Overall,” Linhares said, “our study demonstrated that with the availability of standard operating procedures, specially trained staff and a multidisciplinary team trained in CAR T toxicity management, inpatient and outpatient CAR T administration is feasible at specialized community medical centers.”

In 2023, another study examined patients with B-cell non-Hodgkin lymphoma who were treated on an outpatient basis with tisagenlecleucel. Researchers reported that outpatient therapy was “feasible and associated with similar efficacy outcomes as inpatient treatment.”

And a 2023 systematic literature review identified 11 studies that reported outpatient vs inpatient outcomes in CAR T-cell therapy and found “comparable response rates (80-82% in outpatient and 72-80% in inpatient).” Costs were cheaper in the outpatient setting. 

Research findings like these are good news, Baylor College of Medicine’s Badr said. “Outpatient administration could help to scale the availability of this therapy to a broader range of healthcare settings, including those serving underserved populations. Findings indicate promising safety profiles, which is encouraging for expanding access.”
 

Not Every Patient Can Tolerate Outpatient Care

Linhares noted that the patients who received outpatient care in the lisocabtagene maraleucel study were in better shape than those in the inpatient group. Those selected for inpatient care had “higher disease risk characteristics, including high grade B cell lymphoma histology, higher disease burden, and having received bridging therapy. This points to the fact that the investigators properly selected patients who were at a higher risk of complications for inpatient observation. Additionally, some patients stayed as inpatient due to social factors, which increases length of stay independently of disease characteristics.”

Specifically, reasons for inpatient monitoring were disease characteristics (48%) including tumor burden and risk of adverse events; psychosocial factors (32%) including lack of caregiver support or transportation; COVID-19 precautions (8%); pre-infusion adverse events (8%) of fever and vasovagal reaction; and principal investigator decision (4%) due to limited hospital experience with CAR T-cell therapy.

Texas Children’s Cancer Center’s Rouce said “certain patients, particularly those with higher risk for complications or those who require intensive monitoring, may not be suited for outpatient CAR T-cell therapy. This may be due to other comorbidities or baseline factors known to predispose to CAR T-related toxicities. However, evidence-based risk mitigation algorithms may still allow closely monitored outpatient treatment, with recognition that hospital admission for incipient side effects may be necessary.”
 

What’s Next for Access to Therapy?

Rouce noted that her institution, like many others, is offering CAR T-cell therapy on an outpatient basis. “Additionally, continued scientific innovation, such as immediately available, off-the-shelf cell therapies and inducible safety switches, will ultimately improve access,” she said. 

Linhares noted a recent advance and highlighted research that’s now in progress. “CAR Ts now have an indication as a second-line therapy in relapsed/refractory large B-cell lymphoma, and there are ongoing clinical trials that will potentially move CAR Ts into the first line,” she said. “Some trials are exploring allogeneic, readily available off-the-shelf CAR T for the treatment of minimal residual disease positive large B-cell lymphoma after completion of first-line therapy.”

These potential advances “are increasing the need for CAR T-capable medical centers,” Linhares noted. “More and more medical centers with expert hematology teams are becoming CAR T-certified, with more patients having access to CAR T.”

Still, she said, “I don’t think access is nearly as good as it should be. Many patients in rural areas are still unable to get this life-saving treatment. “However, “it is very possible that other novel targeted therapies, such as bispecific antibodies, will be used in place of CAR T in areas with poor CAR T access. Bispecific antibody efficacy in various B cell lymphoma histologies are being currently explored.”

TOPLINE:

Between 2011 and 2023, the US Food and Drug Administration (FDA) reported recalls of 334 cosmetic dermatology products in the United States, affecting over 77 million units, predominantly due to bacterial contamination.

METHODOLOGY:

• Researchers conducted a cross-sectional analysis of the FDA Enforcement Report database for cosmetic dermatology products from 2011 to 2023.
• Cosmetic products are any article “intended for body cleaning or beauty enhancement,” as defined by the FDA.
• Recalls were categorized by product type, reason for the recall, microbial contaminant, inorganic contaminant, distribution, and risk classification.

TAKEAWAY:

• During the study period, 334 voluntary and manufacturer-initiated recalls of cosmetic products were reported, affecting 77,135,700 units.
• A total of 297 recalls (88.9%) were categorized as Class II, indicating that they caused “medically reversible health consequences.” The median recall duration was 307 days.
• Hygiene and cleaning products accounted for most of the recalls (51.5%). Makeup gels, soaps, shampoos, tattoo ink, wipes, and lotions were the most recalled product categories. Nearly 51% of the products were distributed internationally.
• Microbial and inorganic contamination accounted for 76.8% and 10.2% of the recalls (the two most common reasons for the recall), respectively, with bacteria (80%) the most common contaminating pathogen (primarily Pseudomonas and Burkholderia species).

IN PRACTICE:

With 77 million units recalled by the FDA over 12 years, cosmetic recalls have remained common, the authors concluded, adding that “dermatologists should be key voices in pharmacovigilance given scientific expertise and frontline experience managing products and associated concerns.” Dermatologists, they added, “should also be aware of FDA enforcement reports for recall updates given that average recall termination took approximately 1 year.”

SOURCE:

The study was led by Kaushik P. Venkatesh, MBA, MPH, Harvard Medical School, Boston, and was published online on October 29 in the Journal of the American Academy of Dermatology.

LIMITATIONS: 

The study’s limitations include the potential underreporting of Class III recalls (products that are unlikely to cause any adverse health reaction but violate FDA labeling or manufacturing laws) and lack of complete information on contaminants.

DISCLOSURES:

No information on funding was provided in the study. No conflicts of interest were reported.
