Approximately 1 in 20 adults with outpatient respiratory syncytial virus (RSV) infections were readmitted to the hospital within 28 days, based on new data from more than 67,000 cases.

RSV remains a top cause of acute respiratory tract infections among adults in the United States, with an estimated 159,000 hospitalizations in those aged 65 years or older, wrote Suzanne N. Landi, MPH, PhD, of Pfizer in New York City, and colleagues in a study published in JAMA Network Open.

“Currently, limited estimates exist to determine the risk of hospitalization following outpatient RSV disease diagnoses in the United States,” said corresponding author Joshua T. Swan, PharmD, MPH, in an interview.

The current study was conducted to inform development of clinical trials, said Swan, senior director and category clinician in internal medicine and disease development at Pfizer, the sponsor of the study. These trials would assess the efficacy of an outpatient RSV antiviral treatment in preventing RSV-related hospitalization within 28 days among adults at a high risk for progression to severe illness, he said.

The authors reviewed data from 67,239 adults aged 18 years or older with medically attended RSV infections between October 1, 2016, and September 30, 2022. The data came from three databases: Optum (2771 patients), TriNetX (7442 patients), and Veradigm Network Electronic Health Record (VNEHR; 57,026 patients).

The primary outcome was all-cause hospitalization within 28 days of medically attended RSV.

Overall, the proportions of patients hospitalized within 28 days of infection were 6.2%, 6.0%, and 4.5% in Optum, TriNetX, and VNEHR databases, respectively.

Approximately two thirds of the patients (62%-67% across the three databases) were women, and 14.0%-54.5% were aged 65 years or older. The researchers also identified comorbidity prevalences of 20.0%-30.5% for chronic obstructive pulmonary disease (COPD), 14.6%-24.4% for heart failure (HF), and 14.6%-24.4% for asthma.

A majority of the patients (ranging from 74.5% to 90.6% across the three databases) fell into a high-risk subgroup, defined as age 65 years or older with asthma, COPD, and HF. In this high-risk group, the proportions of hospitalizations were 7.6%, 8.5%, and 6.5% for Optum, TriNetX, and VNEHR, respectively.

The findings were limited by several factors, including the use only of data from outpatient settings, which cannot be used to estimate the RSV burden in the general population, and the reliance only on diagnosis or procedure codes to identify comorbidities, the researchers noted.

However, “the absolute risk of hospitalization of 1 out of 20 patients observed in our study represents significant and meaningful risk for vulnerable adults, in a disease where much of the public’s attention has historically focused on risk of hospitalization for young children,” Swan said. “These results highlight the unmet medical need for outpatient interventions and preventive measures that can reduce hospitalizations.” 

 

Don’t Underestimate RSV Impact

The current study highlights the fact that RSV is a major cause of respiratory viral illness, said David R. Manoff, MD, associate professor of clinical thoracic medicine and surgery at Temple University, Philadelphia, in an interview.

“Historically, influenza, and, more recently, COVID-19 infection have generally been thought of as more likely to cause harm and, thus, have been more emphasized in terms of both vaccination and treatment,” said Manoff, who was not involved in the study.

The current study provides new evidence that infection with RSV can be far more serious than often recognized and a major potential source of both hospitalization and morbidity, Manoff said. In fact, data published in Morbidity and Mortality Weekly Report in 2023 showed that the risks of needing oxygen, intensive care unit (ICU) admission, intubation, and death were actually higher in patients hospitalized with RSV infections than in those hospitalized with influenza or COVID-19. “

Understanding which population is hospitalized in the first place is vital to targeting prevention measures,” he added.

The new data are consistent with previous studies showing that most patients with RSV infection have primarily upper respiratory tract infection–type symptoms, but that a minority will develop lower respiratory tract disease, Manoff noted.

The findings add to the argument for implementation of RSV vaccination, especially in high-risk individuals, and support the need for RSV testing when patients present for care, he said.

However, more research is needed to reflect recent numbers, Manoff said. The study timeframe of 2016-2022 not only precedes commercially available RSV vaccines but also includes the period of increased isolation and masking seen during the COVID-19 pandemic years of 2020-2021. “We need to see if the same trends continue in the post-pandemic era.” 

Additionally, the studies leading to approval of the RSV vaccine showed a reduction in hospitalization with RSV, and it is important to see how this reduction translates in real-world data and whether the RSV vaccines are reducing need for ICU admission, intubation, and death, Manoff said.

The study was funded by Pfizer, and Swan is a Pfizer employee. Manoff had no financial conflicts to disclose.

The persistent epidemic of sexually transmitted infections (STIs) in the United States is showing signs of a slowdown in cases of syphilis, gonorrhea, and chlamydia, according to the latest data from the Centers for Disease Control and Prevention (CDC).

More than 2.4 million cases of these three nationally notifiable STIs were reported in the United States in 2023 but represent a 1.8% decrease from 2022, based on a new CDC report, Sexually Transmitted Infections Surveillance, 2023.

The 2023 report indicates a 7.2% decrease in gonorrhea, which accounts for most of the decrease.

Although syphilis cases increased overall, they did so by only 1% compared with double-digit increases in previous years, according to the report. Primary and secondary syphilis decreased by 10%, compared with 2022 overall, with a 13% decrease in cases among gay and bisexual men.

Congenital syphilis rates increased by 3%. However, the 3% increase represents a significant drop from the 30% increases each year in recent years, according to the report.

Chlamydia rates remained essentially stable, with a decrease of less than 1.0% overall. Reported chlamydia rates increased by 1.3% among men and decreased by 1.7% among women.

Despite the declines, overall disparities persist, with higher rates of STIs among gay and bisexual men, as well as American Indian/Alaska Native, Black/African American, and Hispanic/Latino populations, according to the report.

 

CDC Cautiously Optimistic

The CDC is “guardedly optimistic that the new data represent a turning point in terms of syphilis and gonorrhea,” said Bradley Stoner, MD, director of the CDC’s Division of STD Prevention, in an interview.

However, a tremendous amount of work remains to be done, notably in addressing disparities in care, said Stoner.

New techniques for diagnosis and treatment, such as the increased use of doxycycline (doxy PEP) for the prevention of STIs after sex for high-risk populations with a history of STIs, are likely contributing to the overall decrease, Stoner said. Other contributing factors include improved communication and awareness of STI treatment options at the community level in emergency departments, substance use facilities, and syringe use programs.

Although the United States has not yet turned the corner in reducing STIs, “We are at an inflection point in the epidemic after years of increases,” Stoner told this news organization. “The CDC is committed to keeping the momentum going and turning things around.” Although congenital syphilis rates are slowing down, it remains a significant problem with severe outcomes for mothers and infants, he noted.

The message to healthcare providers on the front lines is to increase awareness, screen widely, and provide effective treatments, Stoner emphasized.

Looking ahead, more research is needed to identify the settings in which prevention tools can be best utilized, such as urgent care or other programs, said Stoner. “My hope is that implementation science research will give us some clues.” In addition, better tools for detection and treatment of STIs are always needed, notably better diagnostics for syphilis, which still requires a blood test, although research is underway for more efficient testing.

 

Spotlight on Disparities, Syphilis

“I think these are very nuanced results,” said David J. Cennimo, MD, associate professor of medicine and pediatrics in the Division of Infectious Disease at Rutgers New Jersey Medical School, Newark, in an interview. “I am happy, on first pass, to see that STI rates have declined.” However, a closer look reveals that most of the improvements are driven by the 7% drop in gonorrhea, while chlamydia and syphilis rates are relatively stable.

The decreases may reflect that the public is receiving the messaging about the need for screening and safer sex. “Clinicians also have been educated on the need for screening,” Cennimo said. However, “we are still 90% above the [STI] rates from 20 years ago.”

Clinicians also must recognize the disparities in STI rates by race and other demographics, Cennimo said. The current report “is a call to make sure that STI and other medical services are targeted to specific groups as needed and are widely available, especially in under-resourced areas.”

“I am still dismayed by the high syphilis rates, which are also resulting in congenital syphilis,” Cennimo said. “Syphilis in pregnancy is very dangerous, and any case of congenital syphilis is a failure of preventive care and screening; it is a potentially devastating disease.

“We have good treatments for STIs, but we must continue to monitor for resistance,” said Cennimo. “More work is needed to reach high-risk individuals and to provide preventive care and screening.” 

The research was supported by the CDC. Stoner and Cennimo had no financial conflicts to disclose.

The causes of shoulder pain may be as common as a traumatic injury or as rare as a systemic inflammatory condition, according to the American Academy of Orthopaedic Surgeons. The combination of joints, tendons, and muscles that make up the shoulder can present diagnostic and clinical challenges, but several experts shared their tips for management.

Evaluation and Diagnosis

Rotator cuff tendinopathy/tendinitis and subacromial bursitis are typically the most common causes of shoulder pain presenting to a primary care provider, said Jason Kolfenbach, MD, a rheumatologist at UC Health, Denver, Colorado, in an interview. “Other causes of shoulder pain may include acromioclavicular osteoarthritis, biceps tendinitis (often a secondary process in the setting of rotator cuff disease), and true glenohumeral joint osteoarthritis,” he said.

Experts estimate that as much as 80% of shoulder pain involves the muscles, tendons, and ligaments surrounding the joint, rather than true arthritis, said Kolfenbach, who was a co-author of a Medscape slideshow on evaluating shoulder pain. In the slideshow, the authors noted that proper evaluation is needed for successful pain management. Some patients may do well with nonsteroidal anti-inflammatory drugs (NSAIDs), rest, ice, and physical therapy, but more serious conditions may require steroids, disease-modifying antirheumatic drugs, or surgery.

If a patient’s joint pain with active range of motion is relieved when an examiner supports the affected limb (passive range of motion), the cause is more likely related to muscles, tendons, or ligaments, Kolfenbach said.

Primary care providers may not be familiar with examination maneuvers to diagnose shoulder pain, although they are often tasked with evaluating and managing these patients, said Kolfenbach.

Education focused on practical aspects of these maneuvers may help improve primary care confidence in utilizing them and lead to more appropriate ordering of imaging testing and better pain management plans for patients, he said.

However, “If there is concern for a true intra-articular process, plain radiographs are recommended to determine if there is loss of cartilage space and/or other anatomic drivers of pain,” he noted. “Even in conditions of documented intra-articular arthritis, such as osteoarthritis, weakness, and atrophy of the surrounding musculature can contribute to joint disability and pain,” he said. For these patients, referral to physical therapy for periarticular strengthening can provide pain relief, he added.

 

Pinning Down the Pain Point

The many different structures within the shoulder that can cause pain make diagnosis a challenge, Nicole Angelo, DO, MS, a physiatrist at the Hospital for Special Surgery, New York City, said in an interview.

Potential sources of pain include the joint of the shoulder itself, the structures within it (labrum, capsule, and ligaments), and the surrounding rotator cuff muscles and tendons, she said. Patients also may experience overlapping pain referred from the neck (cervical spine) related to nerve irritation (cervical radiculopathy) or arthritis, she noted.

“A patient’s history, including mechanism and acuity of injury, as well as exam, specifically weakness in certain movements,” can help determine whether advanced imaging and surgical intervention may be required,” Angelo told this news organization.

Frozen shoulder is the most missed diagnosis of shoulder pain in primary care, Brian Feeley, MD, chief of sports medicine and shoulder surgery at the University of California, San Francisco (UCSF), said in an interview.

Frozen shoulder, also known as adhesive capsulitis, can mimic many other conditions including rotator cuff problems, shoulder arthritis, and biceps problems, Feeley said. “When people have a loss of active and passive range of motion and no evidence of arthritis on x-rays, their diagnosis is most likely frozen shoulder,” he said.

Another challenge for primary care providers is identifying the severity of rotator cuff problems, Feeley said. “I like to think of rotator cuff problems along a spectrum — impingement is inflammation above the rotator cuff and suggests an imbalance between rotator cuff strength and deltoid strength,” said Feeley. “Partial thickness tears are often normal age-related problems but can be a source of pain,” he added.

However, full-thickness tears encompass a range of problems, from very small asymptomatic holes in the rotator cuff to massive tears that require shoulder replacement, Feeley explained. “Tendinopathy, or changes in the collagen organization in the tendon of the rotator cuff, sounds problematic, but most often is either incidental or part of aging,” he added.

 

When Shoulder Pain Isn’t Caused by the Shoulder

Primary care patients presenting with shoulder pain may in fact have a neck or spine problem instead, Feeley told this news organization. “Pain that is in the shoulder blade area or down the arm and into the fingers is usually coming from the neck/cervical spine,” he said.

In some cases, shoulder pain stems from the joints below the shoulder, including the elbow, because of arthritis, tennis elbow (lateral epicondylopathy), or golfer’s elbow (medial epicondylopathy), said Angelo. “Conditions of the elbow and neck can also affect shoulder mechanics or cause someone to use the joint more or less frequently,” she said. The interconnections between the neck and joints of the upper extremity, including referral patterns, complicate the diagnosis of shoulder pain; therefore, careful history-taking and examination of joints both above and below the shoulder are essential, she added.

 

Conservative Care

Shoulder problems often can be managed conservatively with therapeutic exercise focused on maintaining range of motion of the shoulder and strengthening the musculature around the shoulder, Angelo said. “Often, working with a physical therapist to address the mechanics of how the shoulder is moving and how the muscles are firing can help decrease pain and help patients meet their functional goals,” said Angelo. “Injections into the joint, the bursa adjacent to the rotator cuff, and, at times, into the tendons themselves can also be beneficial in relieving pain and improving function,” she said.

In some cases, a short, consistent course of anti-inflammatory medications can be part of a conservative strategy for the management of shoulder pain, Angelo noted.

“Utilizing these medications on an as-needed basis can also help patients improve their ability to sleep, perform their daily activities, and participate in physical therapy,” she said. A course of physical therapy that promotes maintaining shoulder range of motion, strengthening of the rotator cuff musculature, and working on the mechanics between the scapula and humerus is a good first step for most shoulder conditions, Angelo told this news organization.

“If there is concern due to recent trauma, significant weakness, or new/persistent numbness, referral to a specialist should be considered,” she said. If conservative measures including analgesics and exercise have failed to improve shoulder pain, advanced imaging and further interventional treatment may be necessary, Angelo added.

Most shoulder problems can and should be managed nonoperatively, Feeley said. Surgery should be reserved for patients whose shoulder pain has not improved with nonoperative care in most situations, he said. “It is often surprising for patients to hear, but most things in the shoulder actually get better without surgery, and changes on MRI are often normal for age,” Feeley noted. For example, more than 80% of individuals older than 50 will show signs of a labral tear or arthritis in the acromioclavicular joint, he said. “These are incidental findings that don’t need treatment,” he added.

More research is needed to develop more medications to manage pain for all musculoskeletal conditions, including shoulder pain, said Feeley. “But for now, for patients with shoulder pain, I tend to recommend a combination of Tylenol and an NSAID to improve inflammation and reduce pain, and a guided [physical] therapy program at home or in person. The combination of both usually will be successful,” he said.

 

Postsurgical Shoulder Pain

“For patients who have shoulder surgery, the techniques to manage pain around surgery have improved tremendously over the last decade, particularly with multimodal pain management and nerve blocks,” Feeley told this news organization. These advances have tremendously reduced the need for narcotics for pain management beyond the first 72 hours after surgery, he said. “I strongly recommend patients and primary care doctors to stop all narcotics as soon as possible after shoulder surgery, since they are not nearly as effective for management of pain after the first few days, and they should never be used as a sleep aid,” he emphasized.

Managing pain during recovery from shoulder surgery also involves about 6 weeks in a sling to protect the repair, followed by 6 weeks of active motion but no strengthening, then 3 months of strengthening exercises, he said.

The causes of shoulder pain may be as common as a traumatic injury or as rare as a systemic inflammatory condition, according to the American Academy of Orthopaedic Surgeons. The combination of joints, tendons, and muscles that make up the shoulder can present diagnostic and clinical challenges, but several experts shared their tips for management.

Evaluation and Diagnosis

Rotator cuff tendinopathy/tendinitis and subacromial bursitis are typically the most common causes of shoulder pain presenting to a primary care provider, said Jason Kolfenbach, MD, a rheumatologist at UC Health, Denver, Colorado, in an interview. “Other causes of shoulder pain may include acromioclavicular osteoarthritis, biceps tendinitis (often a secondary process in the setting of rotator cuff disease), and true glenohumeral joint osteoarthritis,” he said.

Experts estimate that as much as 80% of shoulder pain involves the muscles, tendons, and ligaments surrounding the joint, rather than true arthritis, said Kolfenbach, who was a co-author of a Medscape slideshow on evaluating shoulder pain. In the slideshow, the authors noted that proper evaluation is needed for successful pain management. Some patients may do well with nonsteroidal anti-inflammatory drugs (NSAIDs), rest, ice, and physical therapy, but more serious conditions may require steroids, disease-modifying antirheumatic drugs, or surgery.

If a patient’s joint pain with active range of motion is relieved when an examiner supports the affected limb (passive range of motion), the cause is more likely related to muscles, tendons, or ligaments, Kolfenbach said.

Primary care providers may not be familiar with examination maneuvers to diagnose shoulder pain, although they are often tasked with evaluating and managing these patients, said Kolfenbach.

Education focused on practical aspects of these maneuvers may help improve primary care confidence in utilizing them and lead to more appropriate ordering of imaging testing and better pain management plans for patients, he said.

However, “If there is concern for a true intra-articular process, plain radiographs are recommended to determine if there is loss of cartilage space and/or other anatomic drivers of pain,” he noted. “Even in conditions of documented intra-articular arthritis, such as osteoarthritis, weakness, and atrophy of the surrounding musculature can contribute to joint disability and pain,” he said. For these patients, referral to physical therapy for periarticular strengthening can provide pain relief, he added.

 

Pinning Down the Pain Point

The many different structures within the shoulder that can cause pain make diagnosis a challenge, Nicole Angelo, DO, MS, a physiatrist at the Hospital for Special Surgery, New York City, said in an interview.

Potential sources of pain include the joint of the shoulder itself, the structures within it (labrum, capsule, and ligaments), and the surrounding rotator cuff muscles and tendons, she said. Patients also may experience overlapping pain referred from the neck (cervical spine) related to nerve irritation (cervical radiculopathy) or arthritis, she noted.

“A patient’s history, including mechanism and acuity of injury, as well as exam, specifically weakness in certain movements,” can help determine whether advanced imaging and surgical intervention may be required,” Angelo told this news organization.

Frozen shoulder is the most missed diagnosis of shoulder pain in primary care, Brian Feeley, MD, chief of sports medicine and shoulder surgery at the University of California, San Francisco (UCSF), said in an interview.

Frozen shoulder, also known as adhesive capsulitis, can mimic many other conditions including rotator cuff problems, shoulder arthritis, and biceps problems, Feeley said. “When people have a loss of active and passive range of motion and no evidence of arthritis on x-rays, their diagnosis is most likely frozen shoulder,” he said.

Another challenge for primary care providers is identifying the severity of rotator cuff problems, Feeley said. “I like to think of rotator cuff problems along a spectrum — impingement is inflammation above the rotator cuff and suggests an imbalance between rotator cuff strength and deltoid strength,” said Feeley. “Partial thickness tears are often normal age-related problems but can be a source of pain,” he added.

However, full-thickness tears encompass a range of problems, from very small asymptomatic holes in the rotator cuff to massive tears that require shoulder replacement, Feeley explained. “Tendinopathy, or changes in the collagen organization in the tendon of the rotator cuff, sounds problematic, but most often is either incidental or part of aging,” he added.

 

When Shoulder Pain Isn’t Caused by the Shoulder

Primary care patients presenting with shoulder pain may in fact have a neck or spine problem instead, Feeley told this news organization. “Pain that is in the shoulder blade area or down the arm and into the fingers is usually coming from the neck/cervical spine,” he said.

In some cases, shoulder pain stems from the joints below the shoulder, including the elbow, because of arthritis, tennis elbow (lateral epicondylopathy), or golfer’s elbow (medial epicondylopathy), said Angelo. “Conditions of the elbow and neck can also affect shoulder mechanics or cause someone to use the joint more or less frequently,” she said. The interconnections between the neck and joints of the upper extremity, including referral patterns, complicate the diagnosis of shoulder pain; therefore, careful history-taking and examination of joints both above and below the shoulder are essential, she added.

The addition of dupilumab significantly reduced itching and hives, compared with placebo, in patients with chronic spontaneous urticaria (CSU) that was uncontrolled with H1-antihistamines, based on data from 151 individuals.

“Approximately 50% of patients with chronic spontaneous urticaria do not respond to antihistamines,” said Thomas B. Casale, MD, professor of internal medicine at the University of South Florida, Tampa, in an interview. Omalizumab, the only biologic approved for this condition, is not effective in all patients, and additional treatment options are needed, added Casale, the lead author who presented the new data, at the American College of Allergy, Asthma & Immunology (ACAAI) 2024 Annual Scientific Meeting.

Dupilumab (Dupixent), a fully human monoclonal antibody that targets the interleukin (IL)–4 and IL-13 pathways, is currently approved in the United States for the treatment of several allergy and dermatology indications, including atopic dermatitis, severe asthma exacerbations, chronic rhinosinusitis with nasal polyps, and prurigo nodularis.

In the study, known as LIBERTY-CSU CUPID Study C, researchers randomized 74 patients with CSU aged 6 years or older to add-on dupilumab subcutaneously every 2 weeks and 77 to placebo. (Patients were omalizumab-naive and had symptomatic CSU, despite treatment with up to four times the approved dose of standard-of-care H1-antihistamines.) Dupilumab doses were 300 mg for adults and adolescents weighing ≥ 60 kg or 200 mg for adolescents weighing < 60 kg and children weighing ≥ 30 kg.

The primary outcomes were Itch Severity Score over 7 days (ISS7; range, 0-21) and Urticaria Activity Score over 7 days (UAS7; range, 0-42).

Over the 24-week study period, patients in the dupilumab group showed significantly greater change from baseline than those in the placebo group on both measures, with least squares mean changes of 8.6 vs 6.1 for ISS7 and 15.9 vs 11.2 for UAS7 (P = .02 for both).

In addition, at 24 weeks, significantly more patients in the dupilumab group than in the placebo group achieved well-controlled disease based on a UAS of 6 or lower (41% vs 23%; P = .005). Significantly more dupilumab-treated patients also achieved a complete response (defined as a UAS of 0), compared with placebo-treated patients (30% vs 18%; P = .02).

Overall rates of treatment-emergent adverse events were 53% for both groups, and safety data were mainly consistent with dupilumab’s known safety profile, the researchers wrote.

The findings were not surprising, as a previous related study, LIBERTY-CSU CUPID Study A, showed that dupilumab was effective for CSU, Casale told this news organization. “This replicate study confirms the previous study and provides evidence for regulatory approval.”

If approved by the Food and Drug Administration (FDA), “dupilumab will provide another therapeutic option for patients with chronic urticaria unresponsive to antihistamines,” Casale commented.

No new safety signals occurred, and the ability to self-administer the medication at home provides an advantage for patients, he added. As for additional research, “analysis of patient characteristics and potential biomarkers that would predict responsiveness is needed.”

 

More Research Needed to Fine-Tune Management

An unmet need persists for patients with CSU whose disease is not adequately controlled by higher-dose H1-antihistamines, Robert G. Micheletti, MD, associate professor of dermatology and medicine at the University of Pennsylvania, Philadelphia, said in an interview. “It is important not only to identify effective add-on therapies for these patients but also to generate data to support insurance coverage and drug access,” said Micheletti, who was not involved in the study.

Also referring to the similar findings reported in the LIBERTY-CSU CUPID Study A, Micheletti said, “as in the earlier study, the results demonstrate significantly reduced itch and urticaria in treated patients compared to placebo.”

“While many providers currently prescribe dupilumab off-label for refractory CSU, FDA approval would improve access to the drug for patients who need it and provide an alternative for patients who may not be good candidates for omalizumab,” he added. However, more research is needed to define optimal management of patients with CSU with inadequate response to omalizumab.

“The LIBERTY-CSU CUPID Study B showed a small improvement in itch severity and urticaria activity among such patients receiving dupilumab,” he noted. “Future work should aim to identify biomarkers and other features predictive of response to various therapies.” 

Study B involved patients with CSU who were uncontrolled on standard-of-care antihistamines and refractory or intolerant to omalizumab, according to Regeneron. 

On November 15, after the ACAAI meeting had ended, the company announced that the FDA had accepted the resubmission of an application for approval of dupilumab for the treatment of CSU in adults and pediatric patients aged 12 years or older not adequately controlled with H1-antihistamines.

The study was supported and sponsored by Sanofi and Regeneron Pharmaceuticals. Casale disclosed serving as a consultant for ALK, ARS Pharma, AstraZeneca, Bryn Pharma, Celgene, Eli Lilly, Genentech, GSK, Jasper, Novartis, Regeneron, and Sanofi and as a speaker for Genentech and Regeneron. Micheletti had no relevant financial conflicts to disclose.

No new safety signals occurred, and the ability to self-administer the medication at home provides an advantage for patients, he added. As for additional research, “analysis of patient characteristics and potential biomarkers that would predict responsiveness is needed.”

 

More Research Needed to Fine-Tune Management

An unmet need persists for patients with CSU whose disease is not adequately controlled by higher-dose H1-antihistamines, Robert G. Micheletti, MD, associate professor of dermatology and medicine at the University of Pennsylvania, Philadelphia, said in an interview. “It is important not only to identify effective add-on therapies for these patients but also to generate data to support insurance coverage and drug access,” said Micheletti, who was not involved in the study.

Also referring to the similar findings reported in the LIBERTY-CSU CUPID Study A, Micheletti said, “as in the earlier study, the results demonstrate significantly reduced itch and urticaria in treated patients compared to placebo.”

“While many providers currently prescribe dupilumab off-label for refractory CSU, FDA approval would improve access to the drug for patients who need it and provide an alternative for patients who may not be good candidates for omalizumab,” he added. However, more research is needed to define optimal management of patients with CSU with inadequate response to omalizumab.

“The LIBERTY-CSU CUPID Study B showed a small improvement in itch severity and urticaria activity among such patients receiving dupilumab,” he noted. “Future work should aim to identify biomarkers and other features predictive of response to various therapies.” 

Study B involved patients with CSU who were uncontrolled on standard-of-care antihistamines and refractory or intolerant to omalizumab, according to Regeneron. 

On November 15, after the ACAAI meeting had ended, the company announced that the FDA had accepted the resubmission of an application for approval of dupilumab for the treatment of CSU in adults and pediatric patients aged 12 years or older not adequately controlled with H1-antihistamines.

The study was supported and sponsored by Sanofi and Regeneron Pharmaceuticals. Casale disclosed serving as a consultant for ALK, ARS Pharma, AstraZeneca, Bryn Pharma, Celgene, Eli Lilly, Genentech, GSK, Jasper, Novartis, Regeneron, and Sanofi and as a speaker for Genentech and Regeneron. Micheletti had no relevant financial conflicts to disclose.

A dermatophyte known as Trichophyton mentagrophytes genotype VII (TMVII) has been identified as the cause of an emerging sexually transmitted fungal infection in four adults in the United States, according to a paper published in the Centers for Disease Control and Prevention’s Morbidity and Mortality Weekly Report.

TMVII is a sexually transmitted fungus that causes genital tinea; the fungus might be misidentified as eczema, psoriasis, or other dermatologic conditions, Jason E. Zucker, MD, an infectious disease specialist at Columbia University Irving Medical Center, New York City, and colleagues wrote.

 

“Dermatophyte infections, including TMVII, are spread through direct skin-to-skin contact,” corresponding author Avrom S. Caplan, MD, a dermatologist at New York University Grossman School of Medicine, New York City, said in an interview.

“In the United States, to our knowledge, the infection has only been in MSM [men who have sex with men], but there have been reports of TMVII in Europe in non-MSM patients, including among patients who traveled to Southeast Asia for sex tourism or partners of people who have been infected with TMVII,” he said.

The four patients were diagnosed with tinea between April 2024 and July 2024, and fungal cultures and DNA sequencing identified TMVII as the cause of the infection. All four patients were cisgender men aged 30-39 years from New York City who reported recent sexual contact with other men; one was a sex worker, two had sex with each other, and one reported recent travel to Europe.

All four patients presented with rashes on the face, buttocks, or genitals; all were successfully treated with antifungals, the authors wrote.

Individuals with genital lesions who are sexually active should be seen by a healthcare provider, and TMVII should be considered, especially in the event of scaly, itchy, or inflamed rashes elsewhere on the body, Caplan told this news organization.

Additionally, “If someone presents for a medical evaluation and has ringworm on the buttocks, face, or elsewhere, especially if they are sexually active, the question of TMVII should arise, and the patient should be asked about possible genital lesions as well,” he said. “Any patient diagnosed with an STI [sexually transmitted infection], including MSM patients, should be evaluated appropriately for other STIs including TMVII.” 

Continued surveillance and monitoring are needed to track TMVII and to better understand emerging infections, Caplan told this news organization. Clinicians can find more information and a dermatophyte registry via the American Academy of Dermatology websites on emerging diseases in general and dermatophytes in particular.

“We also need better access to testing and more rapid confirmatory testing to detect emerging dermatophyte strains and monitor antifungal resistance patterns,” Caplan added. “At this time, we do not have evidence to suggest there is antifungal resistance in TMVII, which also distinguishes it from T indotineae.” 

 

Encourage Reporting and Identify New Infections

“Emerging infections can mimic noninfectious disease processes, which can make the diagnosis challenging,” Shirin A. Mazumder, MD, associate professor and infectious disease specialist at the University of Tennessee Health Science Center, Memphis, said in an interview.

“Monitoring emerging infections can be difficult if the cases are not reported and if the disease is not widespread,” Mazumder noted. Educating clinicians with case reports and encouraging them to report unusual cases to public health helps to overcome this challenge.

In the clinical setting, skin lesions that fail to respond or worsen with the application of topical steroids could be a red flag for TMVII, Mazumder told this news organization. “Since the skin findings of TMVII can closely resemble noninfectious processes such as eczema or psoriasis, the use of topical corticosteroids may have already been tried before the diagnosis of TMVII is considered.” 

Also, location matters in making the diagnosis. TMVII lesions occur on the face, genitals, extremities, trunk, and buttocks. Obtaining a thorough sexual history is important because the fungus spreads from close contact through sexual exposure, Mazumder added.

The most effective treatment for TMVII infections remains to be determined, Mazumder said. “Treatment considerations such as combination treatment with oral and topical antifungal medications vs oral antifungal medication alone is something that needs further research along with the best treatment duration.”

“Determining the rate of transmissibility between contacts, when someone is considered to be the most infectious, how long someone is considered infectious once infected, and rates of reinfection are questions that may benefit from further study,” she added.

Although the current cases are reported in MSM, determining how TMVII affects other patient populations will be interesting as more cases are reported, said Mazumder. “Further understanding of how different degrees of immunosuppression affect TMVII disease course is another important consideration.” 

Finally, determining the rate of long-term sequelae from TMVII infection and the rate of bacterial co-infection will help better understand TMVII, she said.
