Clinician Reviews

Pertussis cases in the United States have increased fourfold compared with the same time period last year, according to data from the Centers for Disease Control and Prevention (CDC). Reports from several states illustrate this trend, thought to be due to reduced immunity across the country.

The Alaska Department of Health issued a statement on its website about the significant increase in pertussis cases in the state during the summer, with 90 cases in July and 61 in August, compared with 24 in June and a total of 26 cases in 2023.

Similarly, the Florida Department of Health reported a pertussis increase in July 2024 that was higher than the June 2024 case count and also above the previous 5-year average.

Experts in these and other states suggest that several factors are driving the nationwide increase, including the fact that fewer people are consistently wearing masks. The mass masking during the COVID-19 pandemic caused a significant drop in pertussis, but the latest data suggest a return to prepandemic levels, and waning immunity likely plays a role as well.

Pertussis, also known as whooping cough, typically begins with symptoms similar to those of the common cold, including runny nose, sneezing, mild fever, and cough, according to the CDC. However, babies with whooping cough may experience trouble breathing rather than a cough. The coughing fits often associated with pertussis may not start until 2 weeks after the onset of other symptoms, according to the CDC.

Those who have been vaccinated against pertussis can still become infected, but the risk is lower, and the illness, if it occurs, is likely to be milder. Complications such as apnea, pneumonia, and convulsions can occur in babies younger than 1 year, especially if they have not been vaccinated, according to the CDC.
 

Beyond Easing Pandemic Precautions

Many respiratory-based infections dipped during the COVID-19 pandemic, almost certainly from the multifactorial interventions of masking, distancing, and the general lack of comingling, said David J. Cennimo, MD, associate professor of medicine & pediatrics in the Division of Infectious Diseases at Rutgers New Jersey Medical School, Newark, New Jersey, in an interview.

The number of cases of many of these diseases returned to previous levels after COVID-19 restrictions were lifted, he said.

“However, we know pertussis immunity wanes over time. Children get DTaP at 2, 4, 6, and 15 months, and a Tdap booster at 11-12 years old gets them to adulthood,” Dr. Cennimo said. Adults should be getting a Tdap every 10 years, he added.

The latest available CDC data indicate that Tdap vaccine coverage in adults is approximately 40%, which means that there may be a large number of susceptible people who can become infected and propagate to others, said Dr. Cennimo.
 

Not Just the Young Ones

A recent pertussis outbreak among college students in Virginia highlighted the fact that the infection can affect all ages, and that the effectiveness of childhood vaccines may decrease over time. The majority of the recently diagnosed cases occurred in individuals who had been previously vaccinated, according to a press release from the Virginia Department of Health.

Clinical Clues

The initial stage of pertussis infection looks like a common cold with symptoms of upper respiratory infection, Dr. Cennimo told this news organization. “Unless there is reason to suspect pertussis exposure, it would almost certainly be missed,” he noted.

The characteristic barking/seal-like cough is mostly seen in children, said Dr. Cennimo. Adults and children can experience coughing fits that can lead to shortness of breath and/or vomiting, which would raise suspicion for pertussis, but is not universally present, he said. The convalescent stage of pertussis can be prolonged and is characterized by chronic coughing. “In the past, pertussis had been called the 100-day cough,” and at that point, treatment is ineffective, Dr. Cennimo said.

In clinical practice, “I advise everyone to get the Tdap vaccine every 10 years,” and remember that the “Td” is the every 10-year tetanus shot as well, Dr. Cennimo told this news organization. Reassure patients that the Tdap can be given with other vaccines, he said, and remind patients that, as with any of the respiratory illnesses, they should stay home if sick, cover a cough, consider wearing a mask in public, and wash hands frequently, he said. 

Dr. Cennimo had no financial conflicts to disclose.

Case: A 38-year-old presents for acute onset runny nose, cough, and fever for the last 3 days. Her children at home have a similar presentation. She believes that she has been managing her symptoms well with Tylenol and rest. The patient is up to date on her COVID and flu shots and was wondering if there was anything else she could have done to prevent her symptoms. She saw a commercial about vitamin C supplements boosting the immune system and was wondering about their efficacy. How would you respond?

Studies of Vitamin C

Linus Pauling, FRS, did a summary of four relatively small published studies of vitamin C and concluded that vitamin C supplementation helped prevent and lessen colds.¹ He mentioned a placebo-controlled study of vitamin C with viral inoculation which did not show any effect. His overall conclusion of efficacy for vitamin C led to the widespread belief that vitamin C was a proven effective therapy to prevent and treat the common cold. Since then, multiple trials and studies have examined the effect of vitamin C on the prevention and treatment of colds.

The Cochrane Review conducted a meta-analysis comparing 29 placebo-controlled trials involving 11,306 participants.² Criteria included vitamin C supplementation of 0.2 g-1 g/day to study its efficacy in preventing the common cold. The analysis showed that supplemental vitamin C did not significantly reduce the incidence of colds. However, there was a statistically significant 8% reduction in adults and 14% in children in the duration of colds. In terms of treatment, there was no evidence of vitamin C’s efficacy.

A 2001 study conducted a small double-blind, randomized control trial to evaluate large doses of vitamin C as treatment for the common cold.³ Volunteers were divided and instructed to take varying doses ranging from 1 to 3 g of vitamin C vs a placebo at the onset of cold-like symptoms. Subjects were expected to assess the duration and severity of their cold. The data showed no significant difference in the severity or duration of cold symptoms between small or large vitamin C doses or placebo.

Summary

While vitamin C is safe, there is no evidence for its ability to prevent the common cold. Although the Cochrane review and more a recent meta-analysis by Hemilä and Chalker demonstrated statistical significance in shortening the duration of symptoms, it was a minimal reduction with little clinical significance. Educating patients that supplemental vitamin C does not prevent colds can help them save money and avoid costs for unnecessary supplements.

BARCELONA, SPAIN — Patients with high-risk stage III resectable melanoma treated with neoadjuvant combination immunotherapy achieved higher event- and recurrence-free survival than patients who received monotherapy with immunotherapy or a targeted agent or targeted therapy plus immunotherapy, according to a large-scale pooled analysis from the International Neoadjuvant Melanoma Consortium.

Importantly, the analysis — presented at the annual meeting of the European Society for Medical Oncology — showed that achieving a major pathological response to neoadjuvant therapy is a key indicator of survival outcomes.

After 3 years of follow-up, the results showed that neoadjuvant therapy is not delaying melanoma recurrence, “it’s actually preventing it,” coinvestigator Hussein A. Tawbi, MD, PhD, Department of Melanoma Medical Oncology, University of Texas MD Anderson Cancer Center, Houston, said in an interview. That’s “a big deal.”

Since 2010, the introduction of novel adjuvant and neoadjuvant therapies for high-risk stage III resectable melanoma has led to incremental gains for patients, said Georgina V. Long, MD, PhD, BSc, chair of Melanoma Medical Oncology and Translational Research at the University of Sydney in Australia, who presented the results.

The first pooled analysis of neoadjuvant therapy in 189 patients, published in 2021, indicated that those who achieved a major pathological response — defined as either a pathological complete response (with no remaining vital tumor) or a near-complete pathological response (with vital tumor ≤ 10%) — had the best recurrence-free survival rates.

In the current study, the researchers expanded their cohort to include 818 patients from 18 centers. Patients received at least one dose of neoadjuvant therapy — either combination immunotherapy, combination of targeted and immunotherapy agents, or monotherapy with either an immune checkpoint inhibitor or a targeted agent.

The median age was 59 years, and 38% of patients were women. The median follow-up so far is 38.8 months.

Overall, the 3-year event-free survival was 74% in patients who received any immunotherapy, 72% in those who received immunotherapy plus a targeted BRAF/MEK therapy, and just 37% in those who received targeted therapy alone. Similarly, 3-year recurrence-free survival rates were highest in patients who received immunotherapy at 77% vs 73% in those who received immunotherapy plus a targeted BRAF/MEK therapy and just 37% in those who received targeted therapy alone.

Looking specifically at progressive death 1 (PD-1)–based immunotherapy regimens, combination therapy led to a 3-year event-free survival rate between 77% and 95%, depending on the specific combinations, vs 64% with PD-1 monotherapy and 37% with combination targeted therapy.

Overall, patients who had a major pathological response were more likely to be recurrence free at 3 years. The 3-year recurrence-free survival was 88% in patients with a complete response, 68% in those with a partial pathological response, and 40% in those without a response.

Patients who received immunotherapy were more likely to have major pathological response. The 3-year recurrence-free survival was about 94% in patients who received combination or monotherapy with immune checkpoint inhibition, and about 87% in those who received immunotherapy plus targeted therapy. The recurrence-free survival rate was much lower in patients given only BRAF/MEK inhibitors.

The current overall survival data, which are still immature, suggested a few differences when stratifying the patients by treatment. Almost all patients with a major pathological response were alive at 3 years, compared with 86% of those with a partial pathological response and 70% of those without a pathological response.

Overall, the results showed that immunotherapy — as either combination or monotherapy — is “quite a bit” better than targeted therapy with BRAF/MEK agents, which offers no substantial benefit, said Dr. Twabi.

“When you see the same pattern happening in study after study, in a very clear, robust way, it actually becomes very powerful,” he explained.

Rebecca A. Dent, MD, MSc, chair of the ESMO Scientific Committee who was not involved in the study, told a press conference that the introduction of immunotherapy and combination immunotherapy has dramatically changed outcomes in melanoma.

Commenting on the current study results, Dr. Dent said that “combination immunotherapy is clearly showing exceptional stability in terms of long-term benefits.”

The question now is what are the toxicities and costs that come with combination immunotherapy, said Dr. Dent, from National Cancer Centre Singapore and Duke-NUS Medical School, Singapore.

No funding source was declared. Dr. Long declared relationships with a variety of companies, including AstraZeneca UK Limited, Bayer Healthcare Pharmaceuticals, Boehringer Ingelheim, Merck Sharp & Dohme, Novartis, and Regeneron. Dr. Twabi declared relationships with Bristol-Myers Squibb, Novartis, Merck, Genentech, GlaxoSmithKline, Eisai, and others. Dr. Dent declared relationships with AstraZeneca, Roche, Eisai, Gilead Sciences, Eli Lilly, Merck, and Pfizer.

The median age was 59 years, and 38% of patients were women. The median follow-up so far is 38.8 months.

Overall, the 3-year event-free survival was 74% in patients who received any immunotherapy, 72% in those who received immunotherapy plus a targeted BRAF/MEK therapy, and just 37% in those who received targeted therapy alone. Similarly, 3-year recurrence-free survival rates were highest in patients who received immunotherapy at 77% vs 73% in those who received immunotherapy plus a targeted BRAF/MEK therapy and just 37% in those who received targeted therapy alone.

Looking specifically at progressive death 1 (PD-1)–based immunotherapy regimens, combination therapy led to a 3-year event-free survival rate between 77% and 95%, depending on the specific combinations, vs 64% with PD-1 monotherapy and 37% with combination targeted therapy.

Overall, patients who had a major pathological response were more likely to be recurrence free at 3 years. The 3-year recurrence-free survival was 88% in patients with a complete response, 68% in those with a partial pathological response, and 40% in those without a response.

Patients who received immunotherapy were more likely to have major pathological response. The 3-year recurrence-free survival was about 94% in patients who received combination or monotherapy with immune checkpoint inhibition, and about 87% in those who received immunotherapy plus targeted therapy. The recurrence-free survival rate was much lower in patients given only BRAF/MEK inhibitors.

The current overall survival data, which are still immature, suggested a few differences when stratifying the patients by treatment. Almost all patients with a major pathological response were alive at 3 years, compared with 86% of those with a partial pathological response and 70% of those without a pathological response.

Overall, the results showed that immunotherapy — as either combination or monotherapy — is “quite a bit” better than targeted therapy with BRAF/MEK agents, which offers no substantial benefit, said Dr. Twabi.

“When you see the same pattern happening in study after study, in a very clear, robust way, it actually becomes very powerful,” he explained.

Rebecca A. Dent, MD, MSc, chair of the ESMO Scientific Committee who was not involved in the study, told a press conference that the introduction of immunotherapy and combination immunotherapy has dramatically changed outcomes in melanoma.

Commenting on the current study results, Dr. Dent said that “combination immunotherapy is clearly showing exceptional stability in terms of long-term benefits.”

The question now is what are the toxicities and costs that come with combination immunotherapy, said Dr. Dent, from National Cancer Centre Singapore and Duke-NUS Medical School, Singapore.

No funding source was declared. Dr. Long declared relationships with a variety of companies, including AstraZeneca UK Limited, Bayer Healthcare Pharmaceuticals, Boehringer Ingelheim, Merck Sharp & Dohme, Novartis, and Regeneron. Dr. Twabi declared relationships with Bristol-Myers Squibb, Novartis, Merck, Genentech, GlaxoSmithKline, Eisai, and others. Dr. Dent declared relationships with AstraZeneca, Roche, Eisai, Gilead Sciences, Eli Lilly, Merck, and Pfizer.

TOPLINE:

Optimal management of blood pressure, A1c levels, low-density lipoprotein cholesterol (LDL-C), albuminuria, smoking, and physical activity may reduce the excess risk for chronic kidney disease (CKD) typically linked to obesity. The protective effect is more pronounced in men, in those with lower healthy food scores, and in users of diabetes medication.

METHODOLOGY:

• Obesity is a significant risk factor for CKD, but it is unknown if managing multiple other obesity-related CKD risk factors can mitigate the excess CKD risk.
• Researchers assessed CKD risk factor control in 97,538 participants with obesity from the UK Biobank and compared them with an equal number of age- and sex-matched control participants with normal body weight and no CKD at baseline.
• Participants with obesity were assessed for six modifiable risk factors: Blood pressure, A1c levels, LDL-C, albuminuria, smoking, and physical activity.
• Overall, 2487, 12,720, 32,388, 36,988, and 15,381 participants with obesity had at most two, three, four, five, and six risk factors under combined control, respectively, with the two or fewer group serving as the reference.
• The primary outcome was incident CKD and the degree of combined risk factor control in persons. The CKD risk and risk factor control in participants with obesity were also compared with CKD incidence in matched normal weight participants.

TAKEAWAY:

• During a median follow-up period of 10.8 years, 3954 cases of incident CKD were reported in participants with obesity and 1498 cases in matched persons of normal body mass index (BMI).
• In a stepwise pattern, optimal control of each additional risk factor was associated with 11% (adjusted hazard ratio [aHR], 0.89; 95% CI, 0.86-0.91) reduction in the incidence of CKD events, down to a 49% reduction in CKD incidence (aHR, 0.51; 95% CI, 0.43-0.61) for combined control of all six risk factors in participants with obesity.
• The protective effect of combined control of risk factors was more pronounced in men vs women, in those with lower vs higher healthy diet scores, and in users vs nonusers of diabetes medication.
• A similar stepwise pattern emerged between the number of risk factors controlled and CKD risk in participants with obesity compared with matched individuals of normal BMI, with the excess CKD risk eliminated in participants with obesity with six risk factors under control.

IN PRACTICE:

“Comprehensive control of risk factors might effectively neutralize the excessive CKD risk associated with obesity, emphasizing the potential of a joint management approach in the prevention of CKD in this population,” the authors wrote.

SOURCE:

The study was led by Rui Tang, MS, Department of Epidemiology, School of Public Health and Tropical Medicine, Tulane University, New Orleans, Louisiana. It was published online in Diabetes, Obesity and Metabolism.

LIMITATIONS:

The evaluated risk factors for CKD were arbitrarily selected, which may not represent the ideal group. The study did not consider the time-varying effect of joint risk factor control owing to the lack of some variables such as A1c. The generalizability of the findings was limited because over 90% of the UK Biobank cohort is composed of White people and individuals with healthier behaviors compared with the overall UK population.

DISCLOSURES:

The study was supported by grants from the US National Heart, Lung, and Blood Institute and the National Institute of Diabetes and Digestive and Kidney Diseases. The authors declared no conflicts of interest.

People who received systemic glucocorticoids during short hospital stays were more than twice as likely to develop new onset diabetes than those who didn’t, reported the authors of a large study that analyzed more than a decade’s worth of patient records.

Rajna Golubic, MD, PhD, of the diabetes trials unit at the University of Oxford, United Kingdom, and colleagues did an observational cohort study, using data from electronic healthcare records of more than patients admitted between January 1, 2013, and October 1, 2023.

They looked for patients who didn’t have a diabetes diagnosis at the time of admission and who were not taking a steroid. Their research was presented this month at the 2024 annual meeting of the European Association for the Study of Diabetes (EASD) in Madrid, Spain.

About 1.8%, of 316, of the 17,258 patients who received systemic glucocorticoids (tablets, injections, or infusions) during their hospital stay developed new-onset diabetes, while this happened to only 0.8%, or 3450, of the 434,348 who did not get these drugs, according to an abstract of the EASD presentation.

The median length of stay was 3 days (2-8) for the group of patients who took steroids, compared with 1 day (1-3) in those who did not. Further analysis showed that, when age and sex were factored in, patients receiving systemic glucocorticoids were more than twice as likely (2.6 times) to develop diabetes as those not receiving the treatment, Dr. Golubic said.

This research builds on previous studies that looked at smaller groups of patients and the diabetes risk in patients with specific conditions, including rheumatoid arthritis, Dr. Golubic said. It may prove helpful for clinicians considering when to employ steroids, which are useful medications for managing inflammation associated with many conditions.

“This gives them a very good estimate of how much more likely people treated with systemic glucocorticoids are to develop new-onset diabetes,” Dr. Golubic said.

Glucocorticoids have for decades been used for managing acute and chronic inflammatory diseases. The link to diabetes has been previously reported in smaller studies and in ones linked to specific conditions such as respiratory disease and rheumatoid arthritis.

Carolyn Cummins, PhD, an associate professor at the University of Toronto, Canada, who was not part of this study, told this news organization she was pleased to see a study of diabetes and steroids done with the scope that Dr. Golubic and colleagues undertook. Dr. Cummins in 2022 published an article titled “Fresh insights into glucocorticoid-induced diabetes mellitus and new therapeutic directions” in Nature Reviews Endocrinology. 

“We know that this is an issue, but we didn’t necessarily know numerically how significant it was,” Dr. Cummins said. “I would say it wasn’t a surprising finding, but it’s nice to actually have the numbers from a large study.”

Dr. Golubic and Dr. Cummins reported no relevant financial relationships.

TOPLINE:

An artificial intelligence (AI)-powered clinical documentation tool helped reduce time spent on electronic health records (EHR) at home for almost 48% physicians, and nearly 45% reported less weekly time spent on EHR tasks outside of normal work hours.

METHODOLOGY:

• Researchers recruited 112 clinicians from family medicine, internal medicine, and general pediatrics in North Carolina and Georgia.
• Patients were divided into an intervention group (n = 85) and control group (n = 55), with the intervention group receiving a 1-hour training program on a commercially available AI tool.
• A seven-question survey was administered to participants before and 5 weeks after the intervention to evaluate their experience.

TAKEAWAY:

• The researchers found 47.1% of clinicians in the intervention group reported spending less time on the EHR at home compared with 14.5% in the control group (P < .001); 44.7% reported decreased weekly time on the EHR outside normal work hours compared with 20% in the control group (P = .003).
• The study revealed 43.5% of physicians who used the AI instrument reported spending less time on documentation after visits compared with 18.2% in the control group (P = .002).
• Further, 44.7% reported less frustration when using the EHR compared with 14.5% in the control group (P < .001).

IN PRACTICE:

“Approximately half of clinicians using the AI-powered clinical documentation tool based on interest reported a positive outcome, potentially reducing burnout. However, a significant subset did not find time-saving benefits or improved EHR experience,” the authors of the study wrote.

SOURCE:

The study was led by Tsai-Ling Liu, PhD, Center for Health System Sciences, Atrium Health in Charlotte, North Carolina. It was published online in JAMA Network Open.

LIMITATIONS:

The researchers reported potential selection and recall bias in both groups. Additional research is needed to find areas of improvement and assess the effects on clinician groups and health systems, they said.

DISCLOSURES:

Andrew McWilliams, MD, MPH, reported receiving grants from the Agency for Healthcare Research Quality, the National Institutes of Health, and the Duke Endowment unrelated to this work. Ajay Dharod, MD, reported his role as an electronic health record consultant for the Association of American Medical College CORE program. Jeffrey Cleveland, MD, disclosed his participation on the Executive Client Council, a noncompensated advisory group, for Nuance/Microsoft.

TOPLINE:

A gastrointestinal (GI)-targeted bitter hop extract reduced hunger and food cravings, as well as post-fast ad libitum energy intake, among women undergoing a 24-hour, water-only fast in a small, randomized crossover trial.

METHODOLOGY:

• Researchers conducted a randomized, double-blind, crossover study with 30 normal-weight women ages 18-40 with BMIs of 18.5-25. The trial design was similar to that used previously to test the intervention among men.
• Participants engaged in a water-only fast for 24 hours (6 p.m. to 6 p.m.) on three occasions and were given an ad libitum meal to break each fast.
• Participants were randomly assigned to one of three treatments: placebo, a high-dose (500 mg) bitter hop–based appetite suppressant (Amarasate), or a low dose (250 mg) of the appetite suppressant.
• Treatment capsules of half the total dose were given twice daily (16 hours and 20 hours into the fast).
• Participants recorded their subjective feelings about appetite and food cravings using a visual analog scale at 30-minute intervals starting 16 hours into the fast.

TAKEAWAY:

• Both the high-dose and low-dose treatment groups experienced a significant reduction in appetite (ie, hunger, fullness, satisfaction, thoughts of food) and food cravings compared with the placebo group.
• Energy intake at the ad libitum meal was 14.3% lower in the high-dose group than the placebo group (P < .05). It was 8.1% lower in the low-dose group, but the difference was not statistically significant.
• In the high-dose group, two participants reported loose stools and one reported heartburn. In the low-dose group, one participant reported loose stools.

IN PRACTICE:

“These data suggest that appetite suppressant co-therapy may be useful in reducing hunger during fasting in women and show that gastrointestinal delivery of bitter compounds may also be an effective method of reducing cravings for food,” the authors wrote.

SOURCE:

The study, led by Edward Walker, PhD, of the New Zealand Institute for Plant and Food Research Limited, Auckland, New Zealand, was published online in Obesity Pillars.

LIMITATIONS:

The study has limitations that affect its application for weight management. First, the study included only normal-weight individuals, which limits extension of the results for weight loss treatments. Second, it involved acute fasting and does not assess any accommodation to the intervention that may occur over longer-term use. An additional limitation is the small number of participants.

DISCLOSURES:

The research was funded by Calocurb Limited. The article processing charge was funded by the New Zealand Institute for Plant and Food Research Limited, a New Zealand government–owned Crown Research Institute. The authors declare no competing financial interests. The New Zealand Institute for Plant and Food Research Limited has licensed a hop extract as a dietary supplement to Calocurb to commercialize and currently holds a minor shareholding in this company.

• Treatment capsules of half the total dose were given twice daily (16 hours and 20 hours into the fast).
• Participants recorded their subjective feelings about appetite and food cravings using a visual analog scale at 30-minute intervals starting 16 hours into the fast.

TAKEAWAY:

• Both the high-dose and low-dose treatment groups experienced a significant reduction in appetite (ie, hunger, fullness, satisfaction, thoughts of food) and food cravings compared with the placebo group.
• Energy intake at the ad libitum meal was 14.3% lower in the high-dose group than the placebo group (P < .05). It was 8.1% lower in the low-dose group, but the difference was not statistically significant.
• In the high-dose group, two participants reported loose stools and one reported heartburn. In the low-dose group, one participant reported loose stools.

IN PRACTICE:

“These data suggest that appetite suppressant co-therapy may be useful in reducing hunger during fasting in women and show that gastrointestinal delivery of bitter compounds may also be an effective method of reducing cravings for food,” the authors wrote.

SOURCE:

The study, led by Edward Walker, PhD, of the New Zealand Institute for Plant and Food Research Limited, Auckland, New Zealand, was published online in Obesity Pillars.

LIMITATIONS:

The study has limitations that affect its application for weight management. First, the study included only normal-weight individuals, which limits extension of the results for weight loss treatments. Second, it involved acute fasting and does not assess any accommodation to the intervention that may occur over longer-term use. An additional limitation is the small number of participants.

DISCLOSURES:

The research was funded by Calocurb Limited. The article processing charge was funded by the New Zealand Institute for Plant and Food Research Limited, a New Zealand government–owned Crown Research Institute. The authors declare no competing financial interests. The New Zealand Institute for Plant and Food Research Limited has licensed a hop extract as a dietary supplement to Calocurb to commercialize and currently holds a minor shareholding in this company.

TOPLINE:

A gastrointestinal (GI)-targeted bitter hop extract reduced hunger and food cravings, as well as post-fast ad libitum energy intake, among women undergoing a 24-hour, water-only fast in a small, randomized crossover trial.

METHODOLOGY:

• Researchers conducted a randomized, double-blind, crossover study with 30 normal-weight women ages 18-40 with BMIs of 18.5-25. The trial design was similar to that used previously to test the intervention among men.
• Participants engaged in a water-only fast for 24 hours (6 p.m. to 6 p.m.) on three occasions and were given an ad libitum meal to break each fast.
• Participants were randomly assigned to one of three treatments: placebo, a high-dose (500 mg) bitter hop–based appetite suppressant (Amarasate), or a low dose (250 mg) of the appetite suppressant.
• Treatment capsules of half the total dose were given twice daily (16 hours and 20 hours into the fast).
• Participants recorded their subjective feelings about appetite and food cravings using a visual analog scale at 30-minute intervals starting 16 hours into the fast.

TAKEAWAY:

• Both the high-dose and low-dose treatment groups experienced a significant reduction in appetite (ie, hunger, fullness, satisfaction, thoughts of food) and food cravings compared with the placebo group.
• Energy intake at the ad libitum meal was 14.3% lower in the high-dose group than the placebo group (P < .05). It was 8.1% lower in the low-dose group, but the difference was not statistically significant.
• In the high-dose group, two participants reported loose stools and one reported heartburn. In the low-dose group, one participant reported loose stools.

MADRID — Patients with type 2 diabetes treated with sodium-glucose cotransporter 2 inhibitors (SGLT2is) show significant reductions in the risk of developing neurodegenerative disorders including Alzheimer’s disease, vascular dementia, and Parkinson’s disease, compared with those treated with other antidiabetic drugs, results from a large population-based cohort show.

“This was the largest nationwide population-based longitudinal cohort study to investigate the association between the use of SGLT2 inhibitors and the incidence of all-cause dementia and Parkinson’s disease,” said first author Hae Kyung Kim, MD, of the Department of Internal Medicine, Yonsei University College of Medicine, Seoul, South Korea, in presenting the findings at the annual meeting of the European Association for the Study of Diabetes.

Type 2 diabetes is known to increase the risk for neurodegenerative diseases such as dementia or Alzheimer’s disease, said Dr. Kim. Key factors attributed to the risk include shared pathophysiological mechanisms such as central nervous system insulin resistance and reduced cerebral glucose metabolism.

While research is lacking on the role of antidiabetic drugs in the treatment of neurodegenerative diseases, the researcher noted that “SGLT2 inhibitors, which have shown significant cardiorenal benefits and enhanced energy metabolism through ketogenesis, offer promise.”

To further investigate, Dr. Kim and her colleagues conducted the retrospective study, evaluating data on more than 1.3 million enrollees in Korea’s National Health Insurance Service Database who were aged 40 years or older, diagnosed with type 2 diabetes, and had initiated antidiabetic drugs between September 2014 and December 2019.

In the propensity score analysis, 358,862 patients were matched 1:1, in groups of 179,431 participants each, based on whether they were treated with SGLT2is or other oral antidiabetic drugs. Patients with a history of neurodegenerative disease, cancer, or use of glucagon-like peptide 1 receptor agonists were excluded.

The patients had a mean age of 57.8 years, 57.9% were men, and 6837 had incident dementia or Parkinson’s disease events reported.

With a mean follow-up of 2.88 years, after adjustment for key variables, those treated with SGLT2is had a 19% reduced risk of developing Alzheimer’s disease (adjusted hazard ratio [aHR], 0.81), a 31% reduced risk for vascular dementia (aHR, 0.69), and a 20% reduced risk for Parkinson’s disease (aHR, 0.80) compared with the non-SGLT2i group.

Furthermore, those receiving SGLT2i treatment had a 21% reduced risk for all-cause dementia (aHR, 0.79) and a 22% reduced risk for all-cause dementia and Parkinson’s disease compared with the oral antidiabetic drug group (aHR, 0.78) with a 6-month drug use lag period.

The association was observed regardless of SGLT2i exposure duration. Subgroup analyses indicated that the reductions in neurodegenerative disorders among those receiving SGLT2is were not associated with factors including age, sex, body mass index, blood pressure, glucose, lipid profiles, kidney function, health behaviors, comorbidities, diabetic complications, or other medication use.

Dr. Kim speculated that mechanisms underlying the reduced dementia risk could include SGLT2i effects of mitigating the common severe risk factors of type 2 diabetes and neurodegenerative diseases, including hypertension, heart failure, and chronic kidney disease, and improving hyperperfusion in the heart and cerebral vascular insufficiency.

Commenting on the study to this news organization, Erik H. Serné, MD, of the VU University Medical Centre, Amsterdam, the Netherlands, who comoderated the session, noted that “people with type 2 diabetes have a 50%-100% increased risk of developing dementia, particularly Alzheimer’s disease and vascular dementia.”

“The increasing prevalence of both conditions poses significant public health challenges, highlighting the need for effective prevention strategies and interventions.”

Currently, treatments for dementia are limited, with most primarily addressing symptoms and not the underlying cause of the neurodegenerative disease, he said.

He noted that, in addition to the effects mentioned by Dr. Kim, SGLT2is are also speculated to provide potential neuroprotective effects through improved glycemic control and insulin sensitivity, reduced inflammation and oxidative stress, enhanced mitochondrial function and energy metabolism, and reduced beta-amyloid and tau pathology.

“These mechanisms collectively may reduce the risk of cognitive decline, particularly in diabetic patients, and warrant further investigation in clinical trials to solidify the neuroprotective role of SGLT2 inhibitors,” said Dr. Serné.

In addition to their benefits in type 2 diabetes, SGLT2is “now offer hope in the prevention of dementia, a disease that has very limited therapeutic options thus far. The current data [presented by Dr. Kim] seem to corroborate this,” he added.

Dr. Kim and Dr. Serné had no disclosures to report.

At age 57, a senior scientific researcher in Santa Barbara, California, complained of chronic erectile dysfunction (ED) in what had been a sexually active marriage. “I just couldn’t get an erection, let alone sustain one. Apart from that, I maybe felt a bit tired but generally okay,” he said. Though seemingly well otherwise, 18 months later he was dead of a hereditary right-sided colon cancer.

While not all cases of ED are associated with a dire outcome, the genitourinary signals of ED and lower urinary tract symptoms (LUTS), especially nocturia, serve as sentinel indicators of the presence of, or risk factors for, serious chronic conditions. These commonly include cardiovascular disease (CVD), diabetes, and metabolic syndrome and are associated with obesity, depression, and obstructive sleep apnea.

Sometimes these serious conditions may stay under the radar until men seek help for ED or LUTS.

“We know that among men who had a heart attack, 50% had some degree of ED within 3 years of their cardiac event,” Sam Tafari, MBBS, of the Endocrine and Metabolic Unit at Royal Adelaide Hospital in Adelaide, South Australia, said in an interview.

That’s the bad news. The good news is that these two problems may specifically incentivize men to seek timely care for serious conditions they might otherwise not get, according to Dr. Tafari. And primary care doctors are ideally positioned to get men early multifaceted care. He recently coauthored a call to action on this issue in a review appearing in the Journal of Men’s Health.

In Dr. Tafari’s experience, most patients seeking urological care are unaware of the multiple conditions linked to ED and LUTS. “Many consider these to be due to issues like low testosterone, which actually make up a very small proportion of cases of ED,” he said. Aging, obesity, inactivity, smoking, alcohol abuse, and prescription and street drugs can also contribute to the development of ED.

In most affected men, ED is of vascular etiology, with endothelial dysfunction of the inner lining of blood vessels and smooth muscle the common denominator.

This dysfunction causes inadequate blood supply to both the coronary and the penile arteries, so ED and CVD are considered different manifestations of the same systemic disorder. Because the tumescence-controlling cavernosal vessels of the penis are considerably smaller, the same level of arteriopathy causes a more severe reduction in blood in the erectile tissue. As a result, ED often precedes CVD and presents an early opportunity to screen men for CVD.

As to the mechanisms behind LUTS, Peter N. Tsambarlis, MD, a urologist at Northwestern Medicine in Chicago, subscribes to the inflammation theory. “Suboptimal health issues such as high [blood] pressure, blood lipids, and blood glucose lead to chronic widespread inflammation, which makes the bladder less flexible as a storage vessel,” he explained. “It’s not able to stretch adequately overnight to hold the urine until morning.”
 

Ask Early, Ask Often

Jeffrey P. Weiss, MD, PhD, chair of the Department of Urology at SUNY Downstate Health Sciences University in Brooklyn, New York, has done research that uncovered a relationship between structural cardiac disease and nocturia. “So if you had to ask a patient a single question that would point to a global health issue, it would be ‘Do you have frequent nighttime urination,’ ” he said.

It’s never too soon to ask men about these symptoms, said Dr. Tsambarlis. The best time to raise issues of ED and LUTS is when a man enters primary care — regardless of age or absence of symptoms. “That way you have a baseline and can watch for changes and do early intervention as needed. Men don’t usually want to bring up sexual dysfunction or urinary health, but asking doesn’t need to dominate the visit,” he said.

Dr. Tafari recommends that primary care physicians adopt a targeted approach using ED and nocturia as entry points for engaging men in their healthcare. While acknowledging that primary care physicians have an ever-growing checklist of questions to ask patients and hardly need one more thing to screen for, he suggests asking two quick, and easy “before you go” genitourinary queries:

• Are you having trouble with erections or having sex?
• Are you getting up at night to pass urine more than once?

“The men really appreciate being asked,” he said. “But what worries me is all the men we don’t see who have these symptoms but don’t know they’re important, and no one is asking about them.”

Gideon Richards, MD, a urologist at the Northwell Health Physician Partners Smith Institute for Urology at Garden City, and director of Men’s Health, Central Region, for Northwell Health in New Hyde Park, both in New York, said erectile problems should not wait for specialty care. By the time men with ED are referred to urology, they may already have failed treatment with first-line phosphodiesterase 5 inhibitor therapy, he said. “A significant proportion will have arteriogenic erectile dysfunction, a measurable decrease in the amount of blood flow into the erectile bodies.”

Addressing the Issue

Addressing genitourinary-signaled issues has the double benefit of easing ED and LUTS and improving men’s health and longevity and may help narrow the worldwide gender gap in life expectancy. As a recent global analysis found, there’s a 5-year longevity disparity favoring women over men. Biology aside, men do not access healthcare as often as women, who consult their general practitioners regularly throughout their lifespan for multiple reasons, including reproductive care, and more screening programs are aimed at women.

Added Dr. Tsambarlis, “Men should know that losing weight and switching to a healthy lifestyle can improve sexual function about half as much as phosphodiesterase 5 inhibitors such as sildenafil [Viagra] or tadalafil [Cialis].”

“Many, however, would prefer just to take drugs rather than change their lifestyle and lose weight. There are certainly effective options available, but these are not uniformly effective,” said Dr. Weiss.

Dr. Tafari’s group is designing a short, simple, culturally acceptable screening tool for use in primary care practice and will monitor its impact on physician prescribing habits and overall men’s health outcomes.

Dr. Tafari received funding from the Hospital Research Foundation and Freemasons Centre for Male Health and Wellbeing in Adelaide, South Australia. Dr. Tafari, Dr. Tsambarlis, Dr. Weiss, and Dr. Richards had no relevant conflicts of interest to declare.

Tsambarlis, MD, a urologist at Northwestern Medicine in Chicago, subscribes to the inflammation theory. “Suboptimal health issues such as high [blood] pressure, blood lipids, and blood glucose lead to chronic widespread inflammation, which makes the bladder less flexible as a storage vessel,” he explained. “It’s not able to stretch adequately overnight to hold the urine until morning.”
 

Ask Early, Ask Often

Jeffrey P. Weiss, MD, PhD, chair of the Department of Urology at SUNY Downstate Health Sciences University in Brooklyn, New York, has done research that uncovered a relationship between structural cardiac disease and nocturia. “So if you had to ask a patient a single question that would point to a global health issue, it would be ‘Do you have frequent nighttime urination,’ ” he said.

It’s never too soon to ask men about these symptoms, said Dr. Tsambarlis. The best time to raise issues of ED and LUTS is when a man enters primary care — regardless of age or absence of symptoms. “That way you have a baseline and can watch for changes and do early intervention as needed. Men don’t usually want to bring up sexual dysfunction or urinary health, but asking doesn’t need to dominate the visit,” he said.

Dr. Tafari recommends that primary care physicians adopt a targeted approach using ED and nocturia as entry points for engaging men in their healthcare. While acknowledging that primary care physicians have an ever-growing checklist of questions to ask patients and hardly need one more thing to screen for, he suggests asking two quick, and easy “before you go” genitourinary queries:

• Are you having trouble with erections or having sex?
• Are you getting up at night to pass urine more than once?

“The men really appreciate being asked,” he said. “But what worries me is all the men we don’t see who have these symptoms but don’t know they’re important, and no one is asking about them.”

Gideon Richards, MD, a urologist at the Northwell Health Physician Partners Smith Institute for Urology at Garden City, and director of Men’s Health, Central Region, for Northwell Health in New Hyde Park, both in New York, said erectile problems should not wait for specialty care. By the time men with ED are referred to urology, they may already have failed treatment with first-line phosphodiesterase 5 inhibitor therapy, he said. “A significant proportion will have arteriogenic erectile dysfunction, a measurable decrease in the amount of blood flow into the erectile bodies.”

Addressing the Issue

Addressing genitourinary-signaled issues has the double benefit of easing ED and LUTS and improving men’s health and longevity and may help narrow the worldwide gender gap in life expectancy. As a recent global analysis found, there’s a 5-year longevity disparity favoring women over men. Biology aside, men do not access healthcare as often as women, who consult their general practitioners regularly throughout their lifespan for multiple reasons, including reproductive care, and more screening programs are aimed at women.

Added Dr. Tsambarlis, “Men should know that losing weight and switching to a healthy lifestyle can improve sexual function about half as much as phosphodiesterase 5 inhibitors such as sildenafil [Viagra] or tadalafil [Cialis].”

“Many, however, would prefer just to take drugs rather than change their lifestyle and lose weight. There are certainly effective options available, but these are not uniformly effective,” said Dr. Weiss.

Dr. Tafari’s group is designing a short, simple, culturally acceptable screening tool for use in primary care practice and will monitor its impact on physician prescribing habits and overall men’s health outcomes.

Dr. Tafari received funding from the Hospital Research Foundation and Freemasons Centre for Male Health and Wellbeing in Adelaide, South Australia. Dr. Tafari, Dr. Tsambarlis, Dr. Weiss, and Dr. Richards had no relevant conflicts of interest to declare.

TOPLINE:

Metformin significantly improved symptoms and resulted in hair regrowth in Black women with treatment-refractory central centrifugal cicatricial alopecia (CCCA), in a retrospective case series.

METHODOLOGY:

• Researchers conducted a case series involving 12 Black women in their 30s, 40s, and 50s, with biopsy-confirmed, treatment-refractory CCCA, a chronic inflammatory hair disorder characterized by permanent hair loss, from the Johns Hopkins University alopecia clinic.
• Participants received CCCA treatment for at least 6 months and had stagnant or worsening symptoms before oral extended-release metformin (500 mg daily) was added to treatment. (Treatments included topical clobetasol, compounded minoxidil, and platelet-rich plasma injections.)
• Scalp biopsies were collected from four patients before and after metformin treatment to evaluate gene expression changes.
• Changes in clinical symptoms were assessed, including pruritus, inflammation, pain, scalp resistance, and hair regrowth, following initiation of metformin treatment.

TAKEAWAY:

• Metformin led to significant clinical improvement in eight patients, which included reductions in scalp pain, scalp resistance, pruritus, and inflammation. However, two patients experienced worsening symptoms.
• Six patients showed clinical evidence of hair regrowth after at least 6 months of metformin treatment with one experiencing hair loss again 3 months after discontinuing treatment.
• Transcriptomic analysis revealed 34 upregulated genes, which included upregulated of 23 hair keratin-associated proteins, and pathways related to keratinization, epidermis development, and the hair cycle. In addition, eight genes were downregulated, with pathways that included those associated with extracellular matrix organization, collagen fibril organization, and collagen metabolism.
• Gene set variation analysis showed reduced expression of T helper 17 cell and epithelial-mesenchymal transition pathways and elevated adenosine monophosphate kinase signaling and keratin-associated proteins after treatment with metformin.

IN PRACTICE:

“Metformin’s ability to concomitantly target fibrosis and inflammation provides a plausible mechanism for its therapeutic effects in CCCA and other fibrosing alopecia disorders,” the authors concluded. But, they added, “larger prospective, placebo-controlled randomized clinical trials are needed to rigorously evaluate metformin’s efficacy and optimal dosing for treatment of cicatricial alopecias.”

SOURCE:

The study was led by Aaron Bao, Department of Dermatology, Johns Hopkins University School of Medicine, Baltimore, and was published online on September 4 in JAMA Dermatology.

LIMITATIONS:

A small sample size, retrospective design, lack of a placebo control group, and the single-center setting limited the generalizability of the study findings. In addition, the absence of a validated activity or severity scale for CCCA and the single posttreatment sampling limit the assessment and comparison of clinical symptoms and transcriptomic changes.

DISCLOSURES:

The study was supported by the American Academy of Dermatology. One author reported several ties with pharmaceutical companies, a pending patent, and authorship for the UpToDate section on CCCA.
