VANCOUVER – Patients who undergo either Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy are at an increased risk of fracture, compared with patients with obesity who do not undergo surgery, according to a new analysis of a predominantly male group of U.S. veterans.

Previous studies involving premenopausal women have found a risk of bone mineral density loss and fracture with bariatric surgery, but little was known about the risk among men. Research has also shown an increase in risk after RYGB, but there is less information on risks associated with sleeve gastrectomy, though it is now the most common surgery for weight loss.

Bone density loss after bariatric surgery has been shown to be significant, according to Eileen H. Koh, MD. “It’s quite a lot of bone loss, quickly,” said Dr. Koh, a graduated fellow from the endocrinology program at the University of California, San Francisco, who is moving to the University of Washington, Seattle.

Those observations generally come from studies of younger women. The purpose of the new study “was to see if we see the same risk of fracture in veterans who are older men, so kind of the opposite of the typical bariatric patient,” said Dr. Koh, who presented the research at the annual meeting of the American Society for Bone and Mineral Research.

The researchers analyzed data from 8,299 U.S. veterans who underwent sleeve gastrectomy (41%), RYGB (51%), adjustable gastric banding (4%), or an unspecified bariatric procedure (4%) between 2000 and 2020. They were matched with 24,877 individuals with obesity who did not undergo surgery. The investigators excluded individuals who were at high risk of fracture because of another condition, such as organ transplantation or dialysis. Men made up 70% of both surgical and nonsurgical groups. The mean age was 52 years for both, and 89% and 88% were not Hispanic or Latino, respectively. The proportion of White individuals was 72% and 64%, and the proportion of Black individuals was 18% and 24%.

After adjustment for demographic variables and comorbidities, bariatric surgery was associated with a 68% increased risk of fracture (hazard ratio, 1.68; 95% confidence interval, 1.57-1.80), including hip fractures (HR, 2.42; 95% CI, 1.98-2.97), spine (HR, 1.82; 95% CI, 1.61-2.06), radius/ulna (HR, 2.38; 95% CI, 2.05-2.77), humerus (HR, 1.56; 95% CI, 1.28-1.89), pelvis (HR, 2.41; 95% CI, 1.68-3.46), and tibia/fibula/ankle (HR, 1.50; 95% CI, 1.33-1.69). Increased fracture risk was associated with RYGB (HR, 1.93; 95% CI, 1.75-2.12) and sleeve gastrectomy (HR, 1.50; 95% CI, 1.33-1.69) but not adjustable gastric banding.

Compared with sleeve gastrectomy, adjustable gastric banding was associated with a decreased risk of fracture (HR, 0.64; 95% CI, 0.49-0.84; P = .0012).

The study’s predominantly male population is important because men also get osteoporosis and are frequently overlooked, according to Anne Schafer, MD, who was the lead author of the study. “Even after they fracture, men are sometimes less likely to get care to prevent the next fracture. We’ve shown here that especially men who are on the older side, who go through surgical weight loss, do have a higher risk of fracture compared to those who are similarly obese but have not had the operation,” said Dr. Schafer, a professor of medicine at the University of California, San Francisco, and chief of endocrinology and metabolism at the San Francisco VA Medical Center.

There are limited data on fracture risk after sleeve gastrectomy. “I think this is one of the first times that I’ve been able to demonstrate that there was a higher risk of fracture with sleeve gastrectomy in comparison with nonsurgical cohorts. Of course, it’s necessary to confirm these findings in further studies, but it’s interesting,” said Julien Paccou, MD, who attended the poster session and was asked for comment. His group’s study of a French population showed an increased fracture risk associated with RYGB but not sleeve gastrectomy. Another study found a reduction of fracture risk associated with sleeve gastrectomy and no difference between RYGB and nonsurgical matched control patients in a Medicare population.

In fact, there is a belief that fracture risk may be lower with sleeve gastrectomy, according to Dr. Schafer. “It’s part of why it’s so popular,” she said.

The reasons for increased fracture risk following surgical weight loss remains unknown, according to Dr. Paccou, but they could include mechanical unloading, loss of lean mass, and hormone and nutrition changes. “There are many, many factors,” said Dr. Paccou, a professor of rheumatology at Hospital Roger Salengro in Lille, France.

The study’s findings of increased risk of fracture after sleeve gastrectomy may be an argument against malabsorption because the procedure shouldn’t affect nutrient absorption. It suggests that other factors are at play. “It’s not the only reason,” Dr. Schafer said.

There are recommendations for postbariatric surgery care to optimize bone health, such as protein intake and calcium and vitamin D targets, along with lifestyle factors. “Despite all those [efforts], we still know that bone loss occurs,” Dr. Koh said. In fact, the group is conducting a study funded by Amgen of the use of denosumab (Prolia) for the prevention of high-turnover bone loss after RYGB and sleeve gastrectomy.

Dr. Schafer has received research support from Bone Health Technologies and Amgen. Dr. Koh and Dr. Paccou have disclosed no relevant financial relationships.

VANCOUVER – The use of tricyclic antidepressants (TCAs) conferred the highest risk for a new, first-time clinical fracture in people with type 2 diabetes with overweight or obesity, independent of any prevalent neuropathy, according to findings from an analysis of a large, randomized clinical trial.

Although the findings are suggestive, they don’t definitively pin blame on TCAs, said Rachel Elam, MD, who presented the study at the annual meeting of the American Society for Bone and Mineral Research. “I think that there’s not enough information to conclude that tricyclic antidepressants directly lead to fractures, but I think it opens the door [to] something we should look into more. Is it being mediated by a better predictor, or is it the medication itself? I think it’s more hypothesis generating,” said Dr. Elam, an assistant professor of medicine in the division of rheumatology at the Medical College of Georgia, Augusta.

Patients with type 2 diabetes are known to be at increased risk of fracture, but prediction tools tend to underestimate this risk, Dr. Elam said. “Type 2 diabetes–specific clinical risk factors may be helpful for finding out fracture risk in this population,” Dr. Elam said during her talk.

Glycemic control is one candidate risk factor because advanced glycation end products are linked to reduced bone strength. Other factors include antidiabetic medication use, neuropathy, and microvascular disease, which has been linked to increased cortical porosity.

The study examined a somewhat younger population than previous surveys, having drawn from the Look AHEAD-C clinical trial, which examined the effects of an intensive lifestyle intervention on type 2 diabetes. Look AHEAD-C included 4,697 participants aged 45-75 from 16 U.S. clinical sites. Participants had a body mass index of 25.0 kg/m² or higher and hemoglobin A1c levels of 11% or below.

Dr. Elam cited the database’s inclusion of factors like A1c levels, renal parameters, and diabetic neuropathy. “It gave us a really good population to look at those risk factors” in a large group of people with type 2 diabetes, she said.

Over a median follow-up of 16.6 years, there were 649 participants with incident first clinical fracture(s). Statistically significant factors predicting fracture risk included TCA use (hazard ratio, 2.24; 95% confidence interval, 1.14-4.43), female gender (HR, 2.20; 95% CI, 1.83-2.66), insulin use (HR, 1.26; 95% CI, 1.02-1.57), increases in A1c level (per 1% increase: HR, 1.12; 95% CI, 1.04-1.20), age (HR, 1.02; 95% CI, 1.01-1.04), other or mixed race/ethnicity (HR, 0.68; 95% CI, 0.52-0.87), Hispanic White race/ethnicity (HR, 0.60; 95% CI, 0.39-0.91), non-Hispanic Black race/ethnicity (HR, 0.35; 95% CI, 0.26-0.47), and estrogen use (HR, 0.65; 95% CI, 0.44-0.98).

During the Q&A session following the presentation, Elsa Strotmeyer, PhD, commented that TCAs have been linked to central nervous system pathways in falls in other populations. “It’s a very nice study. It’s important to look at the diabetes complications related to the fracture risk, but I thought that they should have emphasized some more of the diabetes complications being related to fracture rather than these tricyclic antidepressants, because that is not a unique factor to that population,” said Dr. Strotmeyer, who is an associate professor of epidemiology at the University of Pittsburgh.

Instead, she noted a different strength of the study. “The study population is important because they’re a relatively young population with type 2 diabetes, compared to many studies [that] have been published in older populations. Showing similar things that we found in older populations was the unique piece and the important piece of this study,” Dr. Strotmeyer said.

Ultimately, the model wasn’t sufficient to be used as a fall risk predictor, but it should inform future work, according to Dr. Elam. “I think it does lay some new groundwork that when we’re looking forward, it may [help in building] other models to better predict fracture risk in type 2 diabetes. Things that would be important to include [in future models] would be medication use, such as tricyclic antidepressants,” and to make sure we include glycemic control, A1c, and insulin medication.

The study was independently funded. Dr. Elam and Dr. Strotmeyer report no relevant financial relationships.

The Food and Drug Administration has approved a topical combination of 1.2% clindamycin phosphate, 0.15% adapalene, and 3.1% benzoyl peroxide for the treatment of acne vulgaris in patients aged 12 years and older, according to a press release from the manufacturer.

The combination of an antibiotic, a retinoid, and an antibacterial in a gel formulation will be marketed as Cabtreo, and is expected to be available in the first quarter of 2024, according to Ortho Dermatologics.

The treatment was evaluated in a pair of phase 3 multicenter, randomized, controlled trials of 363 patients with moderate to severe acne, according to the company. Approximately 50% of patients across both studies met the primary endpoint of treatment success after 12 weeks of daily use, compared with 24.9% and 20.4% of placebo patients on vehicle in studies 1 and 2, respectively. Treatment success in both studies was defined as a reduction of at least two grades from baseline on the Evaluator’s Global Severity Score (EGSS) with scores of clear (0) or almost clear (1), and absolute change from baseline in both inflammatory and noninflammatory lesions. Patients were evaluated at 2, 4, 8, and 12 weeks.

Patients in the treatment groups for both studies had significantly greater absolute mean reductions in both inflammatory and noninflammatory lesions from baseline to week 12, compared with those in the vehicle group. The mean reductions with the treatment vs. vehicle were 75.7% vs. 59.6% and 72.7% vs. 47.6% for inflammatory and noninflammatory lesions, respectively, in study 1, and 80.1% vs. 56.2% and 73.3% vs. 49.0% for inflammatory and noninflammatory lesions, respectively, in study 2.

The most common adverse events were erythema, application-site reactions, pain, irritation, exfoliation, and dermatitis, all of which were more common in the treatment groups vs. the placebo groups.

The Food and Drug Administration has approved a topical combination of 1.2% clindamycin phosphate, 0.15% adapalene, and 3.1% benzoyl peroxide for the treatment of acne vulgaris in patients aged 12 years and older, according to a press release from the manufacturer.

The combination of an antibiotic, a retinoid, and an antibacterial in a gel formulation will be marketed as Cabtreo, and is expected to be available in the first quarter of 2024, according to Ortho Dermatologics.

The treatment was evaluated in a pair of phase 3 multicenter, randomized, controlled trials of 363 patients with moderate to severe acne, according to the company. Approximately 50% of patients across both studies met the primary endpoint of treatment success after 12 weeks of daily use, compared with 24.9% and 20.4% of placebo patients on vehicle in studies 1 and 2, respectively. Treatment success in both studies was defined as a reduction of at least two grades from baseline on the Evaluator’s Global Severity Score (EGSS) with scores of clear (0) or almost clear (1), and absolute change from baseline in both inflammatory and noninflammatory lesions. Patients were evaluated at 2, 4, 8, and 12 weeks.

Patients in the treatment groups for both studies had significantly greater absolute mean reductions in both inflammatory and noninflammatory lesions from baseline to week 12, compared with those in the vehicle group.

New evidence shows for the first time that the virus that causes COVID directly infects atherosclerotic plaques in the coronary arteries, producing a persistent inflammatory response.

The findings may not only explain the link between COVID and the increased risk of cardiovascular events but mark a starting point for new therapeutic approaches.

“Our study shows there is persistence of viral debris in the artery,” senior investigator Chiara Giannarelli, MD, associate professor of medicine and pathology at NYU Langone Health, New York, said in an interview. “There is an important inflammatory response. We can now look at ways to control this inflammation,” she said.

Dr. Giannarelli says COVID is more than a respiratory virus and that it can affect the whole body. “Our study shows a remarkable ability of the virus to hijack the immune system,” she points out. “Our findings may explain how that happens.”

Dr. Giannarelli says it’s important for doctors and patients to be aware of an increased cardiovascular risk after a SARS-CoV-2 infection and to pay extra attention to traditional risk factors, such as blood pressure and cholesterol.

“This study showing that severe acute respiratory syndrome coronavirus directly infects coronary artery plaques, producing inflammatory substances, really joins the dots and helps our understanding on why we’re seeing so much heart disease in COVID patients,” Peter Hotez, MD, professor of molecular virology and microbiology at Baylor College of Medicine, Houston, said in an interview.

Asked whether this direct infection of vascular plaques was unique to SARS-CoV-2 or whether this may also occur with other viruses, both Dr. Giannarelli and Dr. Hotez said they believe this may be a specific COVID effect.

“I wouldn’t say it is likely that other viruses infect coronary arteries in this way, but I suppose it is possible,” Dr. Giannarelli said.

Dr. Hotez pointed out that other viruses can cause inflammation in the heart, such as myocarditis. “But I can’t think of another virus that stimulates the sequence of events in coronary artery inflammation like we’re seeing here.”

Dr. Giannarelli noted that influenza is also associated with an increased risk of cardiovascular events, but there has been no evidence to date that it directly affects coronary arteries.

Dr. Hotez added that the increased risk of cardiovascular events with influenza has also been reported to be prolonged after the acute infection. “These new findings with SARS-CoV-2 could stimulate a redoubling of efforts to look at this possibility with influenza,” he suggested.
 

Heart disease after COVID

In a recent article published online in Nature Cardiovascular Research, Dr. Giannarelli and colleagues analyzed human autopsy tissue samples from coronary arterial walls of patients who had died from COVID in the early stages of the pandemic in New York.

They found an accumulation of viral RNA in atherosclerotic plaques in the coronary arteries, which was particularly concentrated in lipid-rich macrophage foam cells present within the plaques.

“Our data conclusively demonstrate that severe acute respiratory syndrome coronavirus is capable of infecting and replicating in macrophages within the coronary vasculature,” the researchers report.

The virus preferentially replicates in foam cells, in comparison with other macrophages, they add, suggesting that these cells might act as a reservoir of viral debris in atherosclerotic plaque.

“We have shown that the virus is targeting lipid-rich macrophages in atherosclerotic lesions. This is the first time this has been shown, and we think this is a very important finding,” Dr. Giannarelli said in an interview.

“We also found that the virus persists in these foam cells that could be responsible for long-term, low-grade inflammation in the vasculature that could contribute to the long-term cardiovascular manifestations in patients who have recovered from COVID,” she said.
 

Viral reservoirs

Macrophages residing in vascular tissue can undergo self-renewal and can remain in the tissue for many years, the investigators point out. They suggest that these macrophages may act as viral reservoirs of SARS-CoV-2 RNA in atherosclerotic plaques.

Using an ex vivo model, the researchers also found that atherosclerotic tissue could be directly infected by the virus. And just as was seen in cultured macrophages and foam cells, infection of vascular tissue triggered an inflammatory response. That response induced the secretion of key proatherogenic cytokines, such as interleukin-6 and interleukin-1 beta, which have been implicated in the pathogenesis of atherosclerosis and in an increased risk of cardiovascular events.

“Considering that plaque inflammation promotes disease progression and contributes to plaque rupture, our results provide a molecular basis for how infection of coronary lesions can contribute to the acute cardiovascular manifestations of COVID-19, such as myocardial infarction,” the researchers report.

Another interesting finding was a higher accumulation of viral RNA in the coronary vasculature of the three patients with acute ischemic cardiovascular manifestations, which they say adds to evidence that infection may increase cardiovascular risk.

Dr. Giannarelli points out that the patients in their study died in New York early in the pandemic, before vaccines were available. “They were unvaccinated and likely had little immunity against initial viral strains.”

Dr. Hotez says that when COVID-19 first emerged, many in the medical and scientific communities thought it would closely resemble the original SARS viral infection, which was primarily a respiratory pathogen.

“But it became pretty clear early on this virus was causing a lot of cardiovascular and thromboembolic disease,” he says. “This study provides an insight into the mechanisms involved here.”
 

Affecting more than lungs

Dr. Hotez pointed out that a recent study reported a 5% increase in cardiovascular deaths during the years 2020-2022, compared with before the pandemic.

“Those peaks of cardiovascular deaths corresponded with specific waves of COVID – the first happening at the time of the initial wave with the original virus and second during the Delta wave. So, there’s no question that this virus is contributing to excess cardiovascular mortality, and this paper appears to explain the mechanism.”

Dr. Hotez pointed out that the new findings suggest the cardiovascular risk may be prolonged well after the acute infection resolves.

“In long COVID, a lot of people focus on the neurological effects – brain fog and depression. But cardiac insufficiency and other cardiovascular events can also be considered another element of long COVID,” he said.

Dr. Giannarelli says her group is now studying whether patients with long COVID have virus in their coronary arteries. She points out that the current studies were a result of a team effort between experts in cardiovascular disease and virology and infectious disease. “We need to collaborate more like this to understand better the impact of viral infection in patients and the clinical manifestations,” she said.

Dr. Hotez says he believes these new findings will have implications for the future.

“COVID hasn’t gone away. The numbers have been going up again steadily in the U.S. in the last few months. There are still a significant number of hospitalizations,” he said.

While it would be unwieldy to ask for a cardiology consult for every COVID patient, he acknowledged, “there is probably a subset of people – possibly those of older age and who have had a severe case of COVID – who we suspect are now going to be more prone to cardiovascular disease because of having COVID.

“We should be vigilant in looking for cardiovascular disease in these patients,” Dr. Hotez said, “and perhaps be a bit more aggressive about controlling their cardiovascular risk factors.”

The study was funded by the U.S. National Institutes of Health, the American Heart Association, and the Chan Zuckerberg Initiative.

BERLIN – A novel regulatory T cell–stimulating therapy appears to significantly improve atopic dermatitis in patients with moderate to severe disease and may even benefit quality of life, suggest results from a phase 1b trial.

The research was presented at the annual congress of the European Academy of Dermatology and Venereology.

More than 40 patients were randomly assigned to receive one of two dosages of a highly selective recombinant interleukin (IL)-2 conjugate, rezpegaldesleukin, or placebo for 12 weeks, after which responders were observed out to 48 weeks. The higher dosage was associated with significant improvements in Eczema Area and Severity Index (EASI) and Body Surface Area (BSA) scores, which were maintained over the course of the study, as well as trends for improved patient-reported outcomes.

“This is the first study to demonstrate the therapeutic potential of rezpegaldesleukin,” said presenter Jonathan Silverberg, MD, PhD, MPH, professor of dermatology and director of clinical research at George Washington University, Washington. He added, “These may be some of the most compelling data to date for the field, proving that, at a high level, if you causally increase regulator T cells, you will take down inflammation and improve a disease state.

“For me, this is proof of concept for so many things, and it gets me very excited.”

Dr. Silverberg noted that with the response maintained out to 48 weeks, despite stopping therapy at week 12, the “hope” with the approach of inducing regulator T cells “is that we could induce tolerance and that we could have some potential for disease modification.”

He continued, “Maybe I daren’t use the word ‘cure,’ but can we at least get to something that is truly remitted, where they can stop the drug and maintain that response?”

Dr. Silverberg said rezpegaldesleukin is now being evaluated in a phase 2b study for moderate to severe atopic dermatitis, and a phase 2b trial for alopecia areata is in development.

Tiago dos Reis Matos, MD, PhD, MSc, Amsterdam University Medical Centers, who was not involved in the study, told this news organization that “recombinant human interleukin-2 is an original therapy.”

Instead of blocking or inhibiting inflammation, it stimulates the patient’s immune system to “restore a healthy balance.”

He explained that it “stimulates regulatory T cells, which can be seen as the Peace Corps of the immune system, responsible for maintaining the equilibrium and avoiding uncontrolled inflammation.”

At the meeting, Dr. Silverberg told the audience that although they are the “beneficiaries of riches of new advances” in atopic dermatitis, “still, many observational studies have shown that the majority of patients do not achieve adequate control by the end of their induction periods and clinical trials, in the real world,” with currently available treatments.

Moreover, “there are challenges that come up with any of the different therapies,” he said, with adverse effects an important issue. For example, biologic therapies are associated with conjunctivitis, facial erythema, and arthralgia, and there are boxed warnings for Janus kinase inhibitors.

Dr. Silverberg continued, “Even patients with a favorable response can experience a loss of disease control when they come off therapy.” Consequently, “new strategies are certainly welcome that could potentially induce both deep and potentially therapy-free remission.”

To those ends, he explained that regulatory T cells play a central role in immune homeostasis but have not been “therapeutically relevant until very recently,” when it was posited that increasing their function can “induce that homeostasis, to normalize the inflammatory cascades” seen in a range of conditions, including atopic dermatitis.

Rezpegaldesleukin has high selectivity for regulatory T cells, without causing activation of effector T cells, and has been shown to increase cell numbers in a dose-dependent manner that is sustained for up to 30 days.

The current study involved patients aged 18-70 years with moderate to severe atopic dermatitis and a history of inadequate responses or intolerance to topical medications, and an EASI score ≥ 16.

Participants were randomly assigned to receive subcutaneous rezpegaldesleukin 12 mcg/kg or 24 mcg/kg or placebo every 2 weeks for 12 weeks. They then discontinued treatment and were followed up until week 19, when responders, defined as having a reduction in EASI score ≥ 50%, continued follow-up out to week 48.

Seventeen patients were randomized to higher-dose rezpegaldesleukin, whereas 16 received the lower dose and 10 were assigned to placebo. Dr. Silverberg said that the three groups were “fairly well balanced,” with “fairly good representation” across age, race, and ethnicity groups.

The mean baseline EASI score was between 21.9 and 23.7, and the Validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD) suggested that there was an even split between moderate and severe atopic dermatitis, although the higher-dose rezpegaldesleukin group had more patients with moderate disease.

By week 12, rezpegaldesleukin was associated with significantly greater improvements in EASI scores vs. placebo. Patients on the higher dose had a mean 83% improvement over baseline vs. 65% with the lower dose and 47% with placebo (P = .002 for the higher dose vs. placebo).

Crucially, these differences were maintained up to week 48 in patients, particularly in the higher-dose group.

There was also a nonsignificant increase in the proportion of patients who achieved a reduction in EASI scores ≥ 75% over baseline with the active drug: 41% at week 12 with higher-dose rezpegaldesleukin, 25% with the lower dose, and 20% with placebo. Again, the benefit was maintained up to week 48.

The mean improvement in BSA score from baseline with rezpegaldesleukin was significantly greater than that seen with placebo, at 72% with the higher dose, 55% with the lower dose, and 36% with placebo (P = .0158 for the higher dose vs. placebo).

Although improvements in vIGA-AD scores over baseline with rezpegaldesleukin were not substantial at week 12, by week 48 there was a marked difference between higher-dose rezpegaldesleukin and placebo, with 40.0% of patients responding to the drug vs. 0% in the latter group.

A similar pattern was seen for the Itch Numeric Rating Scale, in which 55.6% of patients treated with higher-dose rezpegaldesleukin responding by week 48, compared with 0% of those who received placebo.

Greater improvements in the Dermatology Life Quality Index (DLQI) and Patient Oriented Eczema Measure (POEM) over baseline with higher-dose rezpegaldesleukin vs. plain placebo were also noted, despite a strong response in the latter group.

Dr. Silverberg reported that all treatment-emergent adverse effects in the two rezpegaldesleukin treatment arms were mild to moderate, with no severe or serious events observed.

The most common adverse events were mild to moderate injection-site reactions, seen in 75.0% of the lower-dose rezpegaldesleukin group and 58.8% the of higher-dose group. There were no cases of conjunctivitis.

The study was sponsored by Eli Lilly and Company in collaboration with Nektar Therapeutics.

Dr. Silverberg said rezpegaldesleukin is now being evaluated in a phase 2b study for moderate to severe atopic dermatitis, and a phase 2b trial for alopecia areata is in development.

Tiago dos Reis Matos, MD, PhD, MSc, Amsterdam University Medical Centers, who was not involved in the study, told this news organization that “recombinant human interleukin-2 is an original therapy.”

Instead of blocking or inhibiting inflammation, it stimulates the patient’s immune system to “restore a healthy balance.”

He explained that it “stimulates regulatory T cells, which can be seen as the Peace Corps of the immune system, responsible for maintaining the equilibrium and avoiding uncontrolled inflammation.”

At the meeting, Dr. Silverberg told the audience that although they are the “beneficiaries of riches of new advances” in atopic dermatitis, “still, many observational studies have shown that the majority of patients do not achieve adequate control by the end of their induction periods and clinical trials, in the real world,” with currently available treatments.

Moreover, “there are challenges that come up with any of the different therapies,” he said, with adverse effects an important issue. For example, biologic therapies are associated with conjunctivitis, facial erythema, and arthralgia, and there are boxed warnings for Janus kinase inhibitors.

Dr. Silverberg continued, “Even patients with a favorable response can experience a loss of disease control when they come off therapy.” Consequently, “new strategies are certainly welcome that could potentially induce both deep and potentially therapy-free remission.”

To those ends, he explained that regulatory T cells play a central role in immune homeostasis but have not been “therapeutically relevant until very recently,” when it was posited that increasing their function can “induce that homeostasis, to normalize the inflammatory cascades” seen in a range of conditions, including atopic dermatitis.

Rezpegaldesleukin has high selectivity for regulatory T cells, without causing activation of effector T cells, and has been shown to increase cell numbers in a dose-dependent manner that is sustained for up to 30 days.

The current study involved patients aged 18-70 years with moderate to severe atopic dermatitis and a history of inadequate responses or intolerance to topical medications, and an EASI score ≥ 16.

Participants were randomly assigned to receive subcutaneous rezpegaldesleukin 12 mcg/kg or 24 mcg/kg or placebo every 2 weeks for 12 weeks. They then discontinued treatment and were followed up until week 19, when responders, defined as having a reduction in EASI score ≥ 50%, continued follow-up out to week 48.

Seventeen patients were randomized to higher-dose rezpegaldesleukin, whereas 16 received the lower dose and 10 were assigned to placebo. Dr. Silverberg said that the three groups were “fairly well balanced,” with “fairly good representation” across age, race, and ethnicity groups.

The mean baseline EASI score was between 21.9 and 23.7, and the Validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD) suggested that there was an even split between moderate and severe atopic dermatitis, although the higher-dose rezpegaldesleukin group had more patients with moderate disease.

By week 12, rezpegaldesleukin was associated with significantly greater improvements in EASI scores vs. placebo. Patients on the higher dose had a mean 83% improvement over baseline vs. 65% with the lower dose and 47% with placebo (P = .002 for the higher dose vs. placebo).

Crucially, these differences were maintained up to week 48 in patients, particularly in the higher-dose group.

There was also a nonsignificant increase in the proportion of patients who achieved a reduction in EASI scores ≥ 75% over baseline with the active drug: 41% at week 12 with higher-dose rezpegaldesleukin, 25% with the lower dose, and 20% with placebo. Again, the benefit was maintained up to week 48.

The mean improvement in BSA score from baseline with rezpegaldesleukin was significantly greater than that seen with placebo, at 72% with the higher dose, 55% with the lower dose, and 36% with placebo (P = .0158 for the higher dose vs. placebo).

Although improvements in vIGA-AD scores over baseline with rezpegaldesleukin were not substantial at week 12, by week 48 there was a marked difference between higher-dose rezpegaldesleukin and placebo, with 40.0% of patients responding to the drug vs. 0% in the latter group.

A similar pattern was seen for the Itch Numeric Rating Scale, in which 55.6% of patients treated with higher-dose rezpegaldesleukin responding by week 48, compared with 0% of those who received placebo.

Greater improvements in the Dermatology Life Quality Index (DLQI) and Patient Oriented Eczema Measure (POEM) over baseline with higher-dose rezpegaldesleukin vs. plain placebo were also noted, despite a strong response in the latter group.

Dr. Silverberg reported that all treatment-emergent adverse effects in the two rezpegaldesleukin treatment arms were mild to moderate, with no severe or serious events observed.

The most common adverse events were mild to moderate injection-site reactions, seen in 75.0% of the lower-dose rezpegaldesleukin group and 58.8% the of higher-dose group. There were no cases of conjunctivitis.

The study was sponsored by Eli Lilly and Company in collaboration with Nektar Therapeutics.

BERLIN – A novel regulatory T cell–stimulating therapy appears to significantly improve atopic dermatitis in patients with moderate to severe disease and may even benefit quality of life, suggest results from a phase 1b trial.

The research was presented at the annual congress of the European Academy of Dermatology and Venereology.

More than 40 patients were randomly assigned to receive one of two dosages of a highly selective recombinant interleukin (IL)-2 conjugate, rezpegaldesleukin, or placebo for 12 weeks, after which responders were observed out to 48 weeks. The higher dosage was associated with significant improvements in Eczema Area and Severity Index (EASI) and Body Surface Area (BSA) scores, which were maintained over the course of the study, as well as trends for improved patient-reported outcomes.

“This is the first study to demonstrate the therapeutic potential of rezpegaldesleukin,” said presenter Jonathan Silverberg, MD, PhD, MPH, professor of dermatology and director of clinical research at George Washington University, Washington. He added, “These may be some of the most compelling data to date for the field, proving that, at a high level, if you causally increase regulator T cells, you will take down inflammation and improve a disease state.

“For me, this is proof of concept for so many things, and it gets me very excited.”

Dr. Silverberg noted that with the response maintained out to 48 weeks, despite stopping therapy at week 12, the “hope” with the approach of inducing regulator T cells “is that we could induce tolerance and that we could have some potential for disease modification.”

He continued, “Maybe I daren’t use the word ‘cure,’ but can we at least get to something that is truly remitted, where they can stop the drug and maintain that response?”

CARLSBAD, CALIF. – According to Delphine J. Lee, MD, PhD, some patients report that their dermatologists tell them there are no effective treatments for vitiligo.

However, this is not supported by the ongoing level of research on vitiligo, with more than 100 randomized controlled trials published over the last 5 years, Dr. Lee, chief of dermatology at Harbor-UCLA Medical Center, Los Angeles, said at the annual symposium of the California Society of Dermatology & Dermatologic Surgery. And, in 2022, ruxolitinib cream became the first FDA-approved treatment for vitiligo. “There’s a lot of research happening now, and I’m pleased to say that despite the fact that some of these medications are not all brand new and exciting, they’re still new in that we have new evidence for them,” she said. “Of the 100 randomized, controlled trials, UV therapy remains a strong part of our armamentarium.”
 

Stabilizing disease

Dr. Lee underscored the importance of stabilizing existing vitiligo and arresting progressive disease, which may be indicated by four key signs: koebnerization; trichrome lesions; inflammation, which can appear as erythema, scaling, and pruritus; and confetti-like macules that are typically 1 mm to 5 mm in size. Key principles of vitiligo treatment are to stop immune destruction and to stimulate melanocyte differentiation, migration, and melanin production, which is “probably why phototherapy is so important and helpful,” she said.

Managing patients’ expectations is also important, added Dr. Lee, who shows patients photos from published clinical trials “so they can see what excellent repigmentation really means.”
 

Dexamethasone vs. mycophenolate

In a randomized, controlled trial published in 2021, researchers compared dexamethasone oral mini-pulse (OMP), 2.5 mg, on two successive days a week, with oral mycophenolate mofetil, 500 mg b.i.d., up to 2 g every day, for 180 days as a stabilizing treatment for patients with progressive, nonsegmental vitiligo, with 90 days of treatment-free follow-up. Assessments included the vitiligo disease activity (VIDA) score, the number of new lesions in the past 30 days, and the Vitiligo Area Scoring Index (VASI). Arrest of disease progression was defined as the absence of any new lesions in the previous 30 days.

Over the treatment and follow-up period, both groups showed a significant trend for reduction in VIDA and in the number of new lesions in the previous 30 days, compared with baseline (P < .001). The difference between VASI at baseline and VASI at 180 and at 270 days was not significant in both groups.

Adverse side effects reported with dexamethasone included acne, weight gain, headache, insomnia, and menstrual irregularity. “The misconception is that because we only give patients a tiny dose of steroids – 2.5 mg two days per week – that they aren’t going to have any side effects,” Dr. Lee commented. “But in fact, they do.” The most common side effects with mycophenolate were nausea and diarrhea. Two patients on mycophenolate discontinued treatment: one for leukopenia and one for transaminitis, but both conditions resolved after treatment was stopped.

The researchers concluded that both dexamethasone OMP and mycophenolate mofetil halt actively spreading vitiligo. “Relapse occurred earlier with mycophenolate, and the relapse rate was higher than with dexamethasone OMP, but this was not statistically significant,” said Dr. Lee, who also leads an immunology research team at The Lundquist Institute at Harbor-UCLA Medical Center.

Other vitiligo treatment options she discussed included the following:

Betamethasone OMP and oral azathioprine. In a comparative study, researchers compared betamethasone OMP with oral azathioprine in arresting disease progression and inducing repigmentation in adults with vitiligo. Significantly more patients in the betamethasone OMP group achieved arrest of progression at 2 months than those in the azathioprine group, but at 6 months the difference was not significant. At 6 months, of the 19 patients who completed 6 months of betamethasone OMP, 2, 2, and 9 patients had more than 20%, 10%-20%, and 5%-10% repigmentation, respectively; and of the 18 patients who completed 6 months of azathioprine, 2 patients had 10%-20% repigmentation, with the remaining patients having no repigmentation or less than 5% repigmentation.

One patient in the azathioprine group developed acute pancreatitis but none developed transaminitis or leukopenia. “Azathioprine is another agent to add to our toolbox,” Dr. Lee said of the study findings. “Both betamethasone OMP and daily azathioprine are effective” in halting disease progression.

Low-dose cyclosporine. In a comparative study, 50 patients with active vitiligo were randomized into two groups: 25 to dexamethasone OMP 2.5 mg on two consecutive days/week for 4 months, and 25 to cyclosporine 3 mg/kg per day for 4 months, stopped treatment, and were then followed up for another 2 months. After 6 months, 84% of patients in the dexamethasone OMP group and 88% of patients in the cyclosporine group achieved arrest of disease progression (P = 1.00), but the mean time to achieve that endpoint was shorter for those in the cyclosporine group, compared with those in the dexamethasone OMP group (a mean of 3.92 weeks vs. 4.12 weeks, respectively; P = .01).

The list of adverse side effects for cyclosporine was “quite lengthy compared to the usual you would expect for dexamethasone,” said Dr. Lee, who was not involved with the study. “This is something we want to take seriously and discuss with our patients. Still, I would say that low-dose cyclosporine is another possibility to add to our toolbox.”

Phototherapy combined with polypodium leucotomos. Dr. Lee highlighted a randomized, controlled trial in which 21 patients with generalized vitiligo received narrow band (NB)-UVB phototherapy plus polypodium leucotomos extract (480 mg b.i.d.) and 21 patients received NB-UVB phototherapy plus placebo. After 6 months of treatment, patients in the NB-UVB plus oral polypodium leucotomos extract group had a better response rate, compared with those in the NB-UVB plus placebo group (47.8% vs. 22%). “We know from studies of polypodium leucotomos that it seems to have an impact on adaptive immunity as well as helps to decrease oxidative stress, so that may help with melanocyte stability in vitiligo,” said Dr. Lee, who was not affiliated with the study. “As with all treatments, the head and neck is very responsive to this combination treatment. The next most responsive area would be the trunk, followed by the extremities, and hands, and feet.”
 

Topical treatments

What about topical options for vitiligo? In a randomized, double-blind, comparative study, researchers evaluated the efficacy and safety of combination treatment with 308-nm excimer light and topical calcipotriol or topical clobetasol ointment for acral vitiligo. Combination treatment (excimer light and topical medication) was applied in the first 12 weeks, followed by topical medication alone for 12 weeks. Calcipotriol 0.005% ointment was applied on one hand vs. clobetasol propionate 0.05% ointment on the other for 24 weeks.

Of the hands treated with excimer light and calcipotriol, 7.7% achieved excellent repigmentation at the end of the combination treatment period and 23% achieved good to excellent improvement after 12 weeks of calcipotriol monotherapy. More than 85% and 77% of the hands treated with calcipotriol-based and clobetasol-based regimens showed some repigmentation at the end of the study, respectively (P < .05). However, no significant difference was found between the two treatments. “The evaluation from study participants was similar in that they felt that there was clearly a difference from baseline, but there was no difference across the two-hand therapy,” Dr. Lee said.

Adverse side effects included the development of blisters in some of patients who received clobetasol. “The take-home here is that you get excellent repigmentation with calcipotriol, though it’s a small percentage, 7.7%,” Dr. Lee said. “No excellent repigmentation was observed with excimer light and topical clobetasol. These data support two possible topical regimens that could be added to phototherapy or excimer light therapy to improve results.”

In another study of 42 patients, researchers compared twice-daily tacrolimus 0.1% ointment with vehicle for facial vitiligo through 24 weeks of intervention and 24 weeks of follow-up. The researchers defined treatment success as a change of 75% or greater in repigmentation of the target lesion between baseline and week 24, as measured by computer imaging software.

They found that 65% of tacrolimus-treated patients achieved therapeutic success, compared with none of the vehicle-treated patients at week 24 (P < .0001). “Tacrolimus is thought to be an old drug, but it does deserve to have continued proper study based on much anecdotal evidence I hear,” Dr. Lee said. “There was also efficacy over vehicle during the 24 weeks of follow-up. I find that tacrolimus works very well on the face. I’ve had very good results in children.”

Another topical option is the cream formulation of the JAK inhibitor ruxolitinib (Opzelura), approved in 2022 for the treatment of nonsegmental vitiligo in patients ages 12 and older, the first FDA-approved treatment for vitiligo. “As with the tacrolimus study, there are patients who achieve 100% repigmentation [with ruxolitinib], but others who may not,” Dr. Lee said. In addition, she noted that the combination of JAK inhibitors with phototherapy is emerging as another possible treatment choice, referring to a recently published systematic review suggesting that concurrent UVB phototherapy appears to improve efficacy of JAK inhibitors for vitiligo.

Dr. Lee reported having no relevant financial disclosures.

CARLSBAD, CALIF. – According to Delphine J. Lee, MD, PhD, some patients report that their dermatologists tell them there are no effective treatments for vitiligo.

Assessments included the vitiligo disease activity (VIDA) score, the number of new lesions in the past 30 days, and the Vitiligo Area Scoring Index (VASI). Arrest of disease progression was defined as the absence of any new lesions in the previous 30 days.

Over the treatment and follow-up period, both groups showed a significant trend for reduction in VIDA and in the number of new lesions in the previous 30 days, compared with baseline (P < .001). The difference between VASI at baseline and VASI at 180 and at 270 days was not significant in both groups.

Adverse side effects reported with dexamethasone included acne, weight gain, headache, insomnia, and menstrual irregularity. “The misconception is that because we only give patients a tiny dose of steroids – 2.5 mg two days per week – that they aren’t going to have any side effects,” Dr. Lee commented. “But in fact, they do.” The most common side effects with mycophenolate were nausea and diarrhea.

Low-dose cyclosporine. In a comparative study, 50 patients with active vitiligo were randomized into two groups: 25 to dexamethasone OMP 2.5 mg on two consecutive days/week for 4 months, and 25 to cyclosporine 3 mg/kg per day for 4 months, stopped treatment, and were then followed up for another 2 months. After 6 months, 84% of patients in the dexamethasone OMP group and 88% of patients in the cyclosporine group achieved arrest of disease progression (P = 1.00), but the mean time to achieve that endpoint was shorter for those in the cyclosporine group, compared with those in the dexamethasone OMP group (a mean of 3.92 weeks vs. 4.12 weeks, respectively; P = .01).

However, this is not supported by the ongoing level of research on vitiligo, with more than 100 randomized controlled trials published over the last 5 years, Dr. Lee, chief of dermatology at Harbor-UCLA Medical Center, Los Angeles, said at the annual symposium of the California Society of Dermatology & Dermatologic Surgery. And, in 2022, ruxolitinib cream became the first FDA-approved treatment for vitiligo. “There’s a lot of research happening now, and I’m pleased to say that despite the fact that some of these medications are not all brand new and exciting, they’re still new in that we have new evidence for them,” she said. “Of the 100 randomized, controlled trials, UV therapy remains a strong part of our armamentarium.”
 

Stabilizing disease

Dr. Lee underscored the importance of stabilizing existing vitiligo and arresting progressive disease, which may be indicated by four key signs: koebnerization; trichrome lesions; inflammation, which can appear as erythema, scaling, and pruritus; and confetti-like macules that are typically 1 mm to 5 mm in size. Key principles of vitiligo treatment are to stop immune destruction and to stimulate melanocyte differentiation, migration, and melanin production, which is “probably why phototherapy is so important and helpful,” she said.

Managing patients’ expectations is also important, added Dr. Lee, who shows patients photos from published clinical trials “so they can see what excellent repigmentation really means.”
 

Dexamethasone vs. mycophenolate

In a randomized, controlled trial published in 2021, researchers compared dexamethasone oral mini-pulse (OMP), 2.5 mg, on two successive days a week, with oral mycophenolate mofetil, 500 mg b.i.d., up to 2 g every day, for 180 days as a stabilizing treatment for patients with progressive, nonsegmental vitiligo, with 90 days of treatment-free follow-up. Assessments included the vitiligo disease activity (VIDA) score, the number of new lesions in the past 30 days, and the Vitiligo Area Scoring Index (VASI). Arrest of disease progression was defined as the absence of any new lesions in the previous 30 days.

Over the treatment and follow-up period, both groups showed a significant trend for reduction in VIDA and in the number of new lesions in the previous 30 days, compared with baseline (P < .001). The difference between VASI at baseline and VASI at 180 and at 270 days was not significant in both groups.

Adverse side effects reported with dexamethasone included acne, weight gain, headache, insomnia, and menstrual irregularity. “The misconception is that because we only give patients a tiny dose of steroids – 2.5 mg two days per week – that they aren’t going to have any side effects,” Dr. Lee commented. “But in fact, they do.” The most common side effects with mycophenolate were nausea and diarrhea. Two patients on mycophenolate discontinued treatment: one for leukopenia and one for transaminitis, but both conditions resolved after treatment was stopped.

The researchers concluded that both dexamethasone OMP and mycophenolate mofetil halt actively spreading vitiligo. “Relapse occurred earlier with mycophenolate, and the relapse rate was higher than with dexamethasone OMP, but this was not statistically significant,” said Dr. Lee, who also leads an immunology research team at The Lundquist Institute at Harbor-UCLA Medical Center.

Other vitiligo treatment options she discussed included the following:

Betamethasone OMP and oral azathioprine. In a comparative study, researchers compared betamethasone OMP with oral azathioprine in arresting disease progression and inducing repigmentation in adults with vitiligo. Significantly more patients in the betamethasone OMP group achieved arrest of progression at 2 months than those in the azathioprine group, but at 6 months the difference was not significant. At 6 months, of the 19 patients who completed 6 months of betamethasone OMP, 2, 2, and 9 patients had more than 20%, 10%-20%, and 5%-10% repigmentation, respectively; and of the 18 patients who completed 6 months of azathioprine, 2 patients had 10%-20% repigmentation, with the remaining patients having no repigmentation or less than 5% repigmentation.

One patient in the azathioprine group developed acute pancreatitis but none developed transaminitis or leukopenia. “Azathioprine is another agent to add to our toolbox,” Dr. Lee said of the study findings. “Both betamethasone OMP and daily azathioprine are effective” in halting disease progression.

Low-dose cyclosporine. In a comparative study, 50 patients with active vitiligo were randomized into two groups: 25 to dexamethasone OMP 2.5 mg on two consecutive days/week for 4 months, and 25 to cyclosporine 3 mg/kg per day for 4 months, stopped treatment, and were then followed up for another 2 months. After 6 months, 84% of patients in the dexamethasone OMP group and 88% of patients in the cyclosporine group achieved arrest of disease progression (P = 1.00), but the mean time to achieve that endpoint was shorter for those in the cyclosporine group, compared with those in the dexamethasone OMP group (a mean of 3.92 weeks vs. 4.12 weeks, respectively; P = .01).

The list of adverse side effects for cyclosporine was “quite lengthy compared to the usual you would expect for dexamethasone,” said Dr. Lee, who was not involved with the study. “This is something we want to take seriously and discuss with our patients. Still, I would say that low-dose cyclosporine is another possibility to add to our toolbox.”

Phototherapy combined with polypodium leucotomos. Dr. Lee highlighted a randomized, controlled trial in which 21 patients with generalized vitiligo received narrow band (NB)-UVB phototherapy plus polypodium leucotomos extract (480 mg b.i.d.) and 21 patients received NB-UVB phototherapy plus placebo. After 6 months of treatment, patients in the NB-UVB plus oral polypodium leucotomos extract group had a better response rate, compared with those in the NB-UVB plus placebo group (47.8% vs. 22%). “We know from studies of polypodium leucotomos that it seems to have an impact on adaptive immunity as well as helps to decrease oxidative stress, so that may help with melanocyte stability in vitiligo,” said Dr. Lee, who was not affiliated with the study. “As with all treatments, the head and neck is very responsive to this combination treatment. The next most responsive area would be the trunk, followed by the extremities, and hands, and feet.”
 

Topical treatments

What about topical options for vitiligo? In a randomized, double-blind, comparative study, researchers evaluated the efficacy and safety of combination treatment with 308-nm excimer light and topical calcipotriol or topical clobetasol ointment for acral vitiligo. Combination treatment (excimer light and topical medication) was applied in the first 12 weeks, followed by topical medication alone for 12 weeks. Calcipotriol 0.005% ointment was applied on one hand vs. clobetasol propionate 0.05% ointment on the other for 24 weeks.

Of the hands treated with excimer light and calcipotriol, 7.7% achieved excellent repigmentation at the end of the combination treatment period and 23% achieved good to excellent improvement after 12 weeks of calcipotriol monotherapy. More than 85% and 77% of the hands treated with calcipotriol-based and clobetasol-based regimens showed some repigmentation at the end of the study, respectively (P < .05). However, no significant difference was found between the two treatments. “The evaluation from study participants was similar in that they felt that there was clearly a difference from baseline, but there was no difference across the two-hand therapy,” Dr. Lee said.

Adverse side effects included the development of blisters in some of patients who received clobetasol. “The take-home here is that you get excellent repigmentation with calcipotriol, though it’s a small percentage, 7.7%,” Dr. Lee said. “No excellent repigmentation was observed with excimer light and topical clobetasol. These data support two possible topical regimens that could be added to phototherapy or excimer light therapy to improve results.”

In another study of 42 patients, researchers compared twice-daily tacrolimus 0.1% ointment with vehicle for facial vitiligo through 24 weeks of intervention and 24 weeks of follow-up. The researchers defined treatment success as a change of 75% or greater in repigmentation of the target lesion between baseline and week 24, as measured by computer imaging software.

They found that 65% of tacrolimus-treated patients achieved therapeutic success, compared with none of the vehicle-treated patients at week 24 (P < .0001). “Tacrolimus is thought to be an old drug, but it does deserve to have continued proper study based on much anecdotal evidence I hear,” Dr. Lee said. “There was also efficacy over vehicle during the 24 weeks of follow-up. I find that tacrolimus works very well on the face. I’ve had very good results in children.”

Another topical option is the cream formulation of the JAK inhibitor ruxolitinib (Opzelura), approved in 2022 for the treatment of nonsegmental vitiligo in patients ages 12 and older, the first FDA-approved treatment for vitiligo. “As with the tacrolimus study, there are patients who achieve 100% repigmentation [with ruxolitinib], but others who may not,” Dr. Lee said. In addition, she noted that the combination of JAK inhibitors with phototherapy is emerging as another possible treatment choice, referring to a recently published systematic review suggesting that concurrent UVB phototherapy appears to improve efficacy of JAK inhibitors for vitiligo.

TOPLINE:

Half of kids with COVID-19 become noninfectious 3 days after testing positive, whether they were vaccinated or not, according to a new study. The findings indicate that return-to-school policies for infected children may not need to differ on the basis of vaccine or booster status.

METHODOLOGY:

• The study looked at 76 children, both vaccinated and unvaccinated, aged 7-18 years who had tested positive for COVID-19. 
• Researchers performed nasal swabs every other day for 10 days, sending the swab to a lab to be tested for cytopathic effect (CPE), or cell death, an indicator of infectivity.
• They took pictures of the lab cultures to look for signs of CPE starting at 6 days after the test, which corresponds to the 2nd day after testing positive.
• If CPE characteristics were present in at least 30% of images, children were considered infectious.

TAKEAWAY:

• By day 3, half of study participants were noninfectious, independent of whether they had been vaccinated.
• By day 5, less than 25% of children were infectious, regardless of vaccination status.
• Among vaccinated children, the duration of infectivity was similar for children who received a booster and for those who had not.
• The authors state that these results are consistent with those of a study in adults with the Omicron variant, which found no association between vaccination status and infectivity duration.

IN PRACTICE:

“Our findings suggest that current policies requiring isolation for 5 days after a positive test might be appropriate, as the majority of children were not infectious by day 5. Additionally, return-to-school policies may not need to discriminate by vaccine or booster status,” the authors wrote. 

SOURCE:

The study was led by Neeraj Sood, PhD, of the University of Southern California in Los Angeles, and was published in JAMA Pediatrics.

LIMITATIONS:

The sample size was small, and the authors identified the potential for nonresponse bias. The research did not include data from children who didn’t receive a test. CPE is the standard for estimating infectivity, but it can still carry inaccuracies.

DISCLOSURES:

The authors report no disclosures. The study was funded by RF Catalytic Capital.

HAMBURG, Germany – Use of some antibiotic and antipsychotic drugs increases the risk of sudden cardiac arrest (SCA) among people with type 2 diabetes who do not have a history of cardiovascular disease (CVD), shows the first such analysis of real-world, primary care data.

People with type 2 diabetes who do not have a history of CVD have almost three times the risk of SCA if they take antipsychotic medications and nearly double the risk if they take certain antibiotics that prolong the QT interval, notably, macrolides and fluoroquinolones.

“These data show that commonly prescribed drugs - antipsychotic medications, used by about 3% of people with type 2 diabetes, and antibiotics, taken by 5% to 10%, convey an increased risk of sudden cardiac arrest in those without a history of cardiovascular disease,” said Peter Harms, MSc, who presented the study at the annual meeting of the European Association for the Study of Diabetes. Another drug associated with an increase in SCA among patients with diabetes was domperidone, an antinausea medication.

“Perhaps these drugs could be avoided in some cases, and GPs should be more aware of the possible consequences of their use,” he added. “If the patient has type 2 diabetes, then maybe it’s better to avoid some of these medications and try and cope without them, or at least find an alternative antibiotic.”

Mr. Harms, an epidemiologist from Amsterdam University Medical Centers, highlighted that their study was unique because the investigators drew upon primary care data. “These data are extensive, and we find a lot of associations which are very real.”

SCA is associated with 50% of all cardiac deaths and accounts for 20% of all mortality in high-income countries. Of those people who experience SCA, 80% of cases prove fatal.

“As the name suggests, it is difficult to predict because it is sudden, especially in people without a cardiovascular disease history,” Mr. Harms pointed out in an interview with this news organization. He highlighted that “around half of those who experience SCA, often between the ages of 40 and 60 years, have never seen a cardiologist, but many do have type 2 diabetes.

“We need to better understand how to recognize people at risk of SCA, know who to watch and how to prevent these events,” he emphasized.

Vladimira Fejfarova, MD, comoderated the session and commented on the study. “From the clinical point of view, it’s necessary to evaluate risk factors that can contribute to sudden cardiac arrest.”

Overall, the researchers found that, among people with type 2 diabetes who do not have a history of CVD, hypoglycemia, severe hypertension, dyslipidemia, and use of QTc-prolonging medications are associated with SCA risk. Among people with type 2 diabetes and CVD, albuminuria and heart failure are associated with SCA risk.

Dr. Fejfarova added: “With type 2 diabetes and also type 1, we need to look more at adverse events, especially when treating infections with macrolides, but also mycotic infections, because antimycotic drugs are known to influence QT intervals that could contribute to sudden cardiac arrest.

“We need to be more cautious with prescribing certain antibiotics that have these side effects in our patients with diabetes,” asserted Dr. Fejfarova, from the Diabetes Centre, Institute for Clinical and Experimental Medicine, Prague.
 

Type 2 diabetes doubles the risk of SCA

The researcher decided to investigate the population of people with type 2 diabetes because their risk of SCD is around twice that of those without type 2 diabetes. Because these patients have relatively frequent checkups with general practitioners, Mr. Harms turned to primary care databases that contained comprehensive and relatively routine information on risk indicators.

Longitudinal associations between clinical characteristics of 3,919 patients with type 2 diabetes – both those with and those without a history of CVD – and SCA (a total of 689 patients) were determined.

Cases were found in the AmsteRdam REsuscitation STtudies (ARREST) registry of out-of-hospital resuscitation attempts by emergency medical services in the Dutch region of Noord-Holland from 2010 to 2019. Case patients were matched with up to five control patients. The control group comprised people with type 2 diabetes who had not experienced an SCA. Control patients were sourced from the same primary care practices who were of similar age and sex. Clinical measurements, including blood pressure and blood glucose readings, medication use, and medical history for the 5 years leading up to an SCA, were obtained from general practice records. A multivariable analysis was performed, and results were stratified for people with and for those without a history of CVD.

Of particular interest were drugs that interfere with cardiac function, including some prokinetic, antibiotic, and antipsychotic medications. All of the drugs are known to be associated with a change in QTc prolongation. Examples include domperidone (QTc-prolonging prokinetic), macrolides and fluoroquinolones (QTc-prolonging antibiotics), and haloperidol (a QTc-prolonging antipsychotic).
 

Antibiotic and antipsychotic use might contribute to SCA in T2D

Case patients and control patients were similar in age, hemoglobin A1c level, and other characteristics with the exception that more patients with SCA had a history of CVD (40.0% vs. 29.4%).

“Looking at the associations in the overall population, insulin use was strongly associated with SCA risk [hazard ratio, 2.38] and perhaps this was an indicator of severity of type 2 diabetes,” remarked Mr. Harms. “Also, unsurprisingly, a history of arrhythmia [HR, 1.68] and, more surprisingly, prokinetic drug use [HR, 1.66; 95% confidence interval, 1.20-2.31], specifically those known for QTc-prolongation, were associated with SCA.”

Among people who had experienced an SCA and who did not have a history of CVD (337 case patients/2,023 control patients), QTc-prolonging antipsychotic medication use was associated with SCA at an HR of 2.87, and antibiotic medication use was associated with SCA at an HR of 1.66. A low fasting glucose level (< 4.5 mmol/mol) was associated with SCA at an HR of 2.5; severely high systolic blood pressure (> 180 mm Hg) was associated with SCA at an HR of 2.21; low HDL cholesterol level, with an HR of 1.35; and high LDL cholesterol level (> 2.6 mmol/L), with an HR of 1.64.

Among people with a history of CVD (352 case patients/1,207 control patients), associations between albuminuria and SCA were moderate (HR, 1.54) and severe (HR, 1.55); heart failure was associated with SCA at an HR of 1.85 (95% CI, 1.50-2.29).

Comoderator Dr. Fejfarova added that, in addition to the findings from Dr. Harms’ study, other research presented in the same session highlighted the importance of checking patients for the presence of arrhythmias that could lead to the development of atrioventricular blocks, sinus node diseases, and SCA.

Mr. Harms and Dr. Fejfarova have disclosed no relevant financial relationships.

Cases were found in the AmsteRdam REsuscitation STtudies (ARREST) registry of out-of-hospital resuscitation attempts by emergency medical services in the Dutch region of Noord-Holland from 2010 to 2019. Case patients were matched with up to five control patients. The control group comprised people with type 2 diabetes who had not experienced an SCA. Control patients were sourced from the same primary care practices who were of similar age and sex. Clinical measurements, including blood pressure and blood glucose readings, medication use, and medical history for the 5 years leading up to an SCA, were obtained from general practice records. A multivariable analysis was performed, and results were stratified for people with and for those without a history of CVD.

Of particular interest were drugs that interfere with cardiac function, including some prokinetic, antibiotic, and antipsychotic medications. All of the drugs are known to be associated with a change in QTc prolongation. Examples include domperidone (QTc-prolonging prokinetic), macrolides and fluoroquinolones (QTc-prolonging antibiotics), and haloperidol (a QTc-prolonging antipsychotic).
 

Antibiotic and antipsychotic use might contribute to SCA in T2D

Case patients and control patients were similar in age, hemoglobin A1c level, and other characteristics with the exception that more patients with SCA had a history of CVD (40.0% vs. 29.4%).

“Looking at the associations in the overall population, insulin use was strongly associated with SCA risk [hazard ratio, 2.38] and perhaps this was an indicator of severity of type 2 diabetes,” remarked Mr. Harms. “Also, unsurprisingly, a history of arrhythmia [HR, 1.68] and, more surprisingly, prokinetic drug use [HR, 1.66; 95% confidence interval, 1.20-2.31], specifically those known for QTc-prolongation, were associated with SCA.”

Among people who had experienced an SCA and who did not have a history of CVD (337 case patients/2,023 control patients), QTc-prolonging antipsychotic medication use was associated with SCA at an HR of 2.87, and antibiotic medication use was associated with SCA at an HR of 1.66. A low fasting glucose level (< 4.5 mmol/mol) was associated with SCA at an HR of 2.5; severely high systolic blood pressure (> 180 mm Hg) was associated with SCA at an HR of 2.21; low HDL cholesterol level, with an HR of 1.35; and high LDL cholesterol level (> 2.6 mmol/L), with an HR of 1.64.

Among people with a history of CVD (352 case patients/1,207 control patients), associations between albuminuria and SCA were moderate (HR, 1.54) and severe (HR, 1.55); heart failure was associated with SCA at an HR of 1.85 (95% CI, 1.50-2.29).

Comoderator Dr. Fejfarova added that, in addition to the findings from Dr. Harms’ study, other research presented in the same session highlighted the importance of checking patients for the presence of arrhythmias that could lead to the development of atrioventricular blocks, sinus node diseases, and SCA.

Mr. Harms and Dr. Fejfarova have disclosed no relevant financial relationships.

Exercising for at least 30 minutes three times a week can be just as effective as Viagra and similar medications at improving erectile function, according to a new analysis of the best research to date on aerobic exercise and erectile function.

The study, published in The Journal of Sexual Medicine, found that aerobic activities – such as walking or cycling – improved erectile function in all men with erectile dysfunction, regardless of body weight, overall health, or medication use. Men with the most severe erectile dysfunction saw the greatest benefit.

“This study provides physicians and patients the proof needed to definitively recommend aerobic activity as part of ED management,” said study author Larry E. Miller, PhD, president, Miller Scientific Consulting, Johnson City, Tenn.

Doctors have long known that erectile function is linked to cardiovascular health, but there is limited high-quality evidence on the impact of exercise on the disorder.

The researchers scoured the scientific literature and found 11 randomized, controlled trials – a preferred study design where participants are randomly assigned to receive an intervention or not. Of the 1,100 men involved in the studies, 600 were assigned to “experimental” groups that typically exercised for 30 to 60 minutes, three to five times a week, while 500 were assigned to “control” groups with no exercise plan.

The worse the ED was, the more exercise helped, the researchers found. On a standardized scale of 6 to 30, men with severe ED who exercised reported a 5-point improvement in erectile function. Those with mild and moderate ED saw improvements of 2 and 3 points, respectively.

By comparison, phosphodiesterase-5 inhibitors – like sildenafil (Viagra) or tadalafil (Cialis) – can lead to improvements of 4 to 8 points, the study authors note. And testosterone replacement therapy can lead to an improvement of 2 points.

“We were particularly impressed by the finding that men with more severe erectile dysfunction saw greater improvements with exercise, and these improvements were similar to those seen in men taking” drugs like Viagra, Dr. Miller said.
 

ED and heart health

Erectile dysfunction can often be traced to the same causes as cardiovascular disease, including inflammation, a narrowing of the arteries (endothelial dysfunction), or a hardening of the arteries (atherosclerosis).

“It’s important to recognize that erectile dysfunction can often serve as an indicator or barometer of underlying cardiovascular health,” said Amy Pearlman, MD, a urologist specializing in male sexual health at Prime Institute in Miami.

Dr. Pearlman was not involved in the study but thinks the results make sense. “It stands to reason that any intervention aimed at enhancing cardiovascular health may also have a positive impact on erectile health.”

But what was surprising was that aerobic exercise reduced symptoms on par with medications like Viagra, said urologist Rahul Mehan, MD, founder of East Valley Urology Center, in Mesa, Ariz. (Dr. Mehan was also not involved in the study.)

While erectile dysfunction medications are generally affordable and accessible, some patients don’t want to take them or can’t tolerate the side effects. These can include “headache, heartburn, nausea, flushing, and pain in muscles, back, arms, or legs,” said Dr. Mehan. He adds, “Everyone can exercise.”

Some doctors, including Dr. Mehan, already recommend exercise to their patients with ED.

Now they can tell patients that it’s “a proven approach backed by high-quality data from randomized studies,” Dr. Miller said. “Exercise is low risk and affordable, making it an ideal first-line treatment option for erectile difficulties, especially for patients unwilling or unable to use medications.”

VANCOUVER – A new calculator that predicts short-term fracture risk at both 1 year and 3 years in patients on dialysis performed well in a study presented at the annual meeting of the American Society for Bone and Mineral Research.

The tool will soon be available on QxMD Calculate, which provides free decision-support tools for physicians, said presenter Andrea Cowan, MD, an assistant professor of medicine at the University of Western Ontario, London.

Dialysis patients have an approximately fivefold increased risk for fracture, Dr. Cowan noted, compared with the general population. However, treatments to prevent fracture risk are relatively limited and can have significant side effects. Therefore, “you really want to make sure that the person you’re targeting for treatment is actually going to be at a reasonable risk of fracture,” she said.

The Fracture Risk Assessment Tool (FRAX) is useful, but it estimates 10-year fracture risk, which is too long of a time frame to be useful for dialysis patients who experience a 50% 5-year mortality, according to Dr. Cowan. It does not take kidney failure or severe hyperparathyroidism into account, and it also requires information like bone mineral density, which poses an additional burden for a dialysis patient already undergoing multiple tests.

The new calculator could also be useful for research because it doesn’t rely on clinical data that might not be generally available, such as parental fracture, smoking status, or body mass index. “There’s a move towards things like pragmatic trials, which use more routinely collected data, have broader inclusion criteria, and are often more cost efficient to run. This calculator should be relatively easy to implement in trials using routinely collected data to perhaps define a subgroup of patients who may be at high risk of fracture without having to apply really cumbersome tools,” Dr. Cowan said.

The researchers included 11,599 patients between ages 40 and 89 years who were treated at a single center in Ontario between 2010 and 2017. The mean age was 66.18 years, 38.6% were women, 64.1% had diabetes, 11.9% had liver disease, and median time on dialysis was 0.81 years. The patients’ median parathyroid hormone level was 30 pmol/L.

At 3 years, the cumulative incidence of any fracture was 7.36% (95% confidence interval, 6.89-7.85), including 2.62% for hip fracture (95% CI, 2.34-2.93), 1.36% for spine fracture (95% CI, 1.16-1.59), 1.93% for wrist or forearm (95% CI, 1.69-2.20), and 2.15% for the pelvis (95% CI, 1.89-2.43). The incidence for all fractures at 1 year was 2.93 (95% CI, 2.62-3.26).

Variables associated with fracture risk included female sex (hazard ratio, 1.46; 95% CI, 1.27-1.67), a previous fracture more than 1 year in the past (HR, 1.65; 95% CI, 1.37-2.00), a fracture in the past year (HR, 3.63; 95% CI, 2.86-4.60), and proton pump inhibitor use (HR, 1.23; 95% CI, 1.04-1.45). After inclusion of vitamin D use, steroid use, time on dialysis, calcium levels, phosphate levels, presence of diabetes, rheumatoid arthritis, and chronic liver disease, the full model had an area under the curve of 77.7 at 1 year (95% CI, 73.3-84.4) and 69.9 at 3 years (95% CI, 68.0-72.2). For hip fracture, the model had an AUC of 80.1 at 1 year (95% CI, 77.0-83.5) and 71.9 at 3 years (95% CI, 70.1-74.2).

During the Q&A session, Dr. Cowan was asked how the tool could be implemented clinically. She said that it could have value in discussing fracture prediction and prevention with patients, but it could also increase fracture risk awareness among nephrologists. “I need to convince a lot of my colleagues because they’re focused on other things, so having this [calculator] I think is both good from a patient as well as a practitioner perspective. And the treatments that we have in people with end-stage renal disease are limited, so you want to know that you’re really targeting the high-risk person before you potentially put them on denosumab and increase the risk of severe hypercalcemia and things like that,” Dr. Cowan said.

The study points out the challenges of predicting fracture risk for specific populations, according to session comoderator Evelyn Hsieh, MD. She noted that the study needs follow-up. “I don’t think they had gotten to a validation [in a separate cohort] yet,” said Dr. Hsieh, an associate professor of medicine (rheumatology) and epidemiology (chronic diseases) at Yale University, New Haven, Conn.

Dr. Cowan and Dr. Hsieh have no relevant financial disclosures.
