Vitamin D deficiency linked to psoriasis severity
, suggesting that some people who increase their intake of the vitamin could better control this skin condition that affects up to 8 million people in the United States alone.
Brown University researchers studied almost 500 psoriasis cases taken from the National Health and Nutrition Examination Survey (NHANES), the scientists told attendees at the conference of the American Society for Nutrition. They compared the peoples’ reports on how much of their body surface was affected by psoriasis to vitamin D levels collected in blood samples.
“After adjusting for lifestyle factors such as smoking, the analysis showed that lower vitamin D levels and vitamin D deficiency were significantly associated with greater psoriasis severity,” the ASN said in a news release. “The researchers also found that patients with the least amount of body surface affected by psoriasis had the highest average vitamin D levels while those with the greatest affected area had the lowest average levels of vitamin D.”
The researchers said that people with psoriasis might improve their condition by getting more vitamin D in their diet and through supplements.
“Topical synthetic vitamin D creams are emerging as new therapies for psoriasis, but these usually require a doctor’s prescription,” said researcher Rachel K. Lim, an MD candidate at Brown University, Providence, R.I. “Our results suggest that a vitamin D–rich diet or oral vitamin D supplementation may also provide some benefit to psoriasis patients.”
The researchers said that vitamin D toxicity is rare but that people should consult with their medical caregivers before they start taking supplements.

Pediatric dermatologists encouraged to counter misinformation on TikTok, other social media sites
ASHEVILLE, N.C. – , warned an expert at the annual meeting of the Society for Pediatric Dermatology.
“If we don’t get involved, we are basically letting misinformation win. We need to be there,” said Angelo Landriscina, MD, director of dermatology at a Mount Sinai Doctors Clinic in New York.
Most of the content currently available on medical topics, including dermatology and pediatric dermatology, is not created by health care professionals, Dr. Landriscina noted. Not surprisingly, given that much of the content is based on personal opinion from individuals who have no expertise in medical care, he described the information as being of “low quality” when not fully erroneous.
Dr. Landriscina has been active on social media, including TikTok, for several years. Most of his posts involve responses to misinformation. When he sets the record straight on the basis of existing evidence, he often supports his counterargument with references.
He acknowledged that when he became involved in social media he faced criticism from colleagues about participating on an entertainment platform that many considered unworthy of providing objective information. If that was ever true, he argued, it is no longer the case.
“TikTok has adopted a new strategy. The goal is to unseat Google as a search tool, and it’s working,” he said. He explained that many people now use TikTok and other social media sites as their primary source of information on essentially every topic, from where to eat to whether to be screened for cancer.
The particular problem with TikTok – one of the most popular social media outlets – is that there is no mechanism for vetting the source of information. YouTube, by contrast, now requires some sort of validation for anyone who claims to have a medical degree or any other verifiable qualification, according to Dr. Landriscina. TikTok, like many other platforms, has no such requirement.
“Anyone can buy a pair of scrubs [implying expertise] and then post a video,” Dr. Landriscina said.
Even if information from one content provider is more valid than information from others, the TikTok algorithm is specifically designed to emphasize content that has the potential for going viral, which means it favors videos that are provocative over those that are not.
“The algorithm favors any content that is more controversial, more surprising, and keeps viewers engaged,” Dr. Landriscina pointed out.
This does not mean that objective and factual information is ignored, but the algorithm is indifferent to the validity of information, meaning that it allows videos to be posted without regard to whether the content is true, untrue, purposefully misleading, or utter nonsense. For that reason, it is often easier to attract attention by responding to a post that has already gone viral. Information that is clear and digestible can attract viewers and therefore is distributed more widely with the TikTok algorithm.
Parents are on Tiktok too
There is a misperception that the TikTok audience is younger, according to Dr. Landriscina. While peak use in the United States fell among people between the ages of 25 and 34 years in 2022, he said the number of users falls off relatively slowly with subsequent 10-year increments in age. In 2022, there were nearly 20 million users in the peak 10-year age range, but 7.5 million users were 55 years of age or older.
“Pediatric dermatologists should recognize that it is not just kids who are looking for information about their skin diseases, but also their parents,” Dr. Landriscina said.
The top three dermatology topics searched on TikTok in a recent period were acne, alopecia, and cysts. But top searches are very fluid and are extremely hard to quantify, because the basis of the algorithm, which is a proprietary secret, is not only unknown but produces different results for every user.
“The second you touch the app, it changes,” Dr. Landriscina said. He explained that an inquiry about any subject, including those that are medically related, yields content that is different, or at least ordered differently, “depending on how you behaved on the app in the past.”
The phenomenon that drives social media predates this technology. Dr. Landriscina cited a study in 1956 that described the “parasocial interaction theory.” The theory was based on the observation that those who consume media, such as television, which was relatively new in 1956, believed that they had a personal relationship with media figures.
“The users begin to trust influencers as a source, like a friend providing them advice,” Dr. Landriscina said. As an example, he suggested that a fan of the television show Friends who follows actor Jennifer Aniston on social media platforms may begin to think of her as a trusted source of information on any topic, including those for which she may not have expertise.
The reason that he urges medical professionals to become active on TikTok and other social media platforms is that they have a potentially critical role in responding to information that is not just wrong but harmful.
On TikTok and other social media platforms, “there is a lot of interest in content about dermatologic conditions in children. There is a real need for accurate information,” he said,
In the question-and-answer session following his presentation, Dr. Landriscina’s message was not uniformly embraced. One risk, according to an audience member, is that medical professionals will begin to express their own personal opinions rather than rely on evidence, with the result that they will “just add to the sea of misinformation.”
However, this opinion appeared to be the minority view. Most of those who commented took a “that-ship-has-sailed” stance, recognizing the irreversible ascendancy of social media.
“Whether you like it or not, social media is here to stay. We cannot fight it. Rather, we need to embrace it in a responsible way,” said Dakara R. Wright, MD, a dermatologist at the Mid-Atlantic Kaiser Permanente Group, Halethorpe, Md. She, like others, reported that she has come to recognize that social media is a major source of medical information for her patients.
“We need to be a presence on these platforms for the benefit of our patients and their parents,” she said. She acknowledged that she has not been active in posting on social media in the past but said that she has been speaking with administrators in her organization about how to become involved in a responsible way that can be useful to patients.
Candrice R. Heath, MD, assistant professor of dermatology at Temple University, Philadelphia, has been active on social media for several years, posting content on her own account, which is not related to her academic affiliation. She posts for many reasons, not least of which is drawing attention to her expertise.
Like Dr. Landriscina, she recognizes that users of these platforms are guided by the content to make decisions about health care. She also agreed that physicians should not ignore this phenomenon.
Tips on providing content
Given the fact that the algorithm is intended to produce posts that go viral, Dr. Landriscina urged clinicians to make their content easy to watch. He said it is not necessary to overthink content beyond providing accurate information, but he advised that videos be made with attention to adequate lighting and other simple factors to promote visual quality. He said that accurate information is not necessarily dull.
“Some facts can actually be surprising to patients,” he said. He noted that a calm, coherent video can be particularly effective in attracting an audience when it is in reaction to information that has gone viral but is misleading or patently incorrect.
Dr. Landriscina has been an influencer associated with multiple social media platforms, including TikTok. He has in the past been paid for consulting work for TikTok. Dr. Wright and Dr. Heath reported no potential conflicts of interest.

‘Treatment holiday’ in prostate cancer with tailored dosing
and improve patient outcomes, new research suggests.
The findings indicate that implementing a personalized dosing strategy with the radioligand therapy “allowed for treatment holidays in excellent responders, continuous 6-weekly treatments in moderate responders, and [allowed us] to consider changing or adding treatment in limited responders,” said study author Andrew Nguyen, MBBS, FRACP, AANMS, senior staff specialist in the department of theranostics and nuclear medicine at St. Vincent’s Hospital in Sydney.
The research was presented at the annual meeting of the Society of Nuclear Medicine and Molecular Imaging.
Although clinical trials have demonstrated that 177Lu-PSMA is an effective treatment for metastatic castration-resistant prostate cancer, the question remains: Can patient outcomes be improved through the use of biomarkers and by escalating or deescalating treatment as appropriate? asked Dr. Nguyen, who presented the findings at the meeting.
Clinical trials use standardized dosing intervals. Adjusting treatment intervals through the use of early-biomarker responses could give some patients a break from treatment and improve overall survival outcomes, Dr. Nguyen explained. For example, the 2021 REALITY study showed that overall survival was significantly better for patients who received 177Lu-PSMA plus standard care, compared with patients who received standard care alone (median, 15.3 vs. 11.3 months), and that overall survival was better among patients with early prostate-specific antigen (PSA) responses.
In the current study, Dr. Nguyen and colleagues used composite early biomarkers of PSA, imaging with 177Lu-PSMA SPECT, and diagnostic CT to guide a personalized dosing interval strategy for patients with metastatic castration-resistant prostate cancer receiving 177Lu-PSMA. The team evaluated progression-free survival and overall survival among these patients to determine whether personalizing dosing on the basis of early biomarker levels was associated with survival outcomes.
The cohort included 125 men who received six weekly doses of 177Lu-PSMA and who underwent imaging with 177Lu-SPECT/CT after each dose. After the second dose, investigators used the composite of PSA and 177Lu SPECT/CT response to determine which patients had a partial response, which had stable disease, and which had progressive disease.
The men were divided into three groups on the basis of their level of response. Group 1, which included 35% of participants, achieved a significant reduction in PSA levels and a partial response on 177Lu-SPECT. These patients were advised to discontinue treatment until PSA levels increased. This treatment holiday lasted a median of about 6 months.
Group 2, which represented 34% of the cohort, had stable or reduced PSA levels as well as stable disease on SPECT imaging. For these patients, the treatment regimen continued.
Group 3 demonstrated rising PSA levels and progressive disease on SPECT imaging. These men were offered an alternative therapy.
Overall, median PSA progression-free survival was 12.1 months in group 1, 6.1 months in group 2, and 2.6 months in group 3. Median overall survival was also significantly better among patients who showed early responses to therapy: 19.2 months in group 1, 13.2 months in group 2, and 11. 2 months in group 3.
Dr. Nguyen noted several limitations to the findings, including the study’s retrospective nature and the fact that some patients in group 1 chose not to resume further treatment after their PSA levels rose.
“Personalizing dosing intervals using early-response biomarkers with 177Lu-PSMA has the potential to achieve similar overall treatment responses to that published for continuous dosing, while allowing treatment holidays in responders and early crossover to potentially more effective therapies in nonresponders,” the authors conclude.
Given the effectiveness of this strategy, Dr. Nguyen says his team “now routinely uses these composite biomarkers when treating clinical patients.”

For example, the 2021 REALITY study showed that overall survival was significantly better for patients who received 177Lu-PSMA plus standard care, compared with patients who received standard care alone (median, 15.3 vs. 11.3 months), and that overall survival was better among patients with early prostate-specific antigen (PSA) responses.
In the current study, Dr. Nguyen and colleagues used composite early biomarkers of PSA, imaging with 177Lu-PSMA SPECT, and diagnostic CT to guide a personalized dosing interval strategy for patients with metastatic castration-resistant prostate cancer receiving 177Lu-PSMA. The team evaluated progression-free survival and overall survival among these patients to determine whether personalizing dosing on the basis of early biomarker levels was associated with survival outcomes.
The cohort included 125 men who received six weekly doses of 177Lu-PSMA and who underwent imaging with 177Lu-SPECT/CT after each dose. After the second dose, investigators used the composite of PSA and 177Lu SPECT/CT response to determine which patients had a partial response, which had stable disease, and which had progressive disease.
The men were divided into three groups on the basis of their level of response. Group 1, which included 35% of participants, achieved a significant reduction in PSA levels and a partial response on 177Lu-SPECT. These patients were advised to discontinue treatment until PSA levels increased. This treatment holiday lasted a median of about 6 months.
Group 2, which represented 34% of the cohort, had stable or reduced PSA levels as well as stable disease on SPECT imaging. For these patients, the treatment regimen continued.
Group 3 demonstrated rising PSA levels and progressive disease on SPECT imaging. These men were offered an alternative therapy.
Overall, median PSA progression-free survival was 12.1 months in group 1, 6.1 months in group 2, and 2.6 months in group 3. Median overall survival was also significantly better among patients who showed early responses to therapy: 19.2 months in group 1, 13.2 months in group 2, and 11. 2 months in group 3.
Dr. Nguyen noted several limitations to the findings, including the study’s retrospective nature and the fact that some patients in group 1 chose not to resume further treatment after their PSA levels rose.
“Personalizing dosing intervals using early-response biomarkers with 177Lu-PSMA has the potential to achieve similar overall treatment responses to that published for continuous dosing, while allowing treatment holidays in responders and early crossover to potentially more effective therapies in nonresponders,” the authors conclude.
Given the effectiveness of this strategy, Dr. Nguyen says his team “now routinely uses these composite biomarkers when treating clinical patients.”

Low HIV levels linked to ‘almost zero’ risk of sexual transmission
BRISBANE, AUSTRALIA – from the World Health Organization.
The announcement was made concurrently with the publication of definitive new research in The Lancet. The findings were presented virtually at the International AIDS Society conference on HIV Science.
The WHO estimates that 76% of the 39 million people worldwide living with HIV take antiretroviral therapy (ART).
“Antiretroviral therapy continues to transform the lives of people living with HIV,” a WHO news release stated. “People living with HIV who are diagnosed and treated early, and take their medication as prescribed, can expect to have the same health and life expectancy as their HIV-negative counterparts.”
The Lancet study showed that people who have a viral load of less than 1,000 copies per milliliter of blood have a tiny chance of transmitting the virus to sexual partners. Of 320 cases of transmission reviewed during the study, only 2 transmissions involved a partner with a load below that threshold. Those cases may have been affected by viral loads rising between the time of testing and transmission. The previous guideline for zero risk of transmission was 200 copies per milliliter.
People living with HIV who do not take ART can have viral loads ranging from 30,000 to more than 500,000 copies per milliliter, according a summary of the study distributed by The Lancet to the media.
The new findings do not apply to the transmission of HIV from mother to child, including during pregnancy, childbirth, and breastfeeding.
“The ultimate goal of antiretroviral therapy for people living with HIV is to maintain undetectable viral loads, which will improve their own health and prevent transmission to their sexual partners and children,” said researcher Lara Vojnov, PhD, diagnostics advisor to the WHO Department of Global HIV, Hepatitis and STI Programmes, in a statement. “But these new findings are also significant as they indicate that the risk of sexual transmission of HIV at low viral loads is almost zero. This provides a powerful opportunity to help destigmatize HIV, promote the benefits of adhering to antiretroviral therapy, and support people living with HIV.”

Rheumatology summit tackles racial disparities in lupus trials
Clinical research in lupus has a mammoth diversity problem: Black individuals are most likely to develop the disease, but they’re the least likely to take part in studies. By the numbers, a 2018 analysis of randomized controlled trials in systemic lupus erythematosus from the years 1997 to 2017 found that 51% of trial participants were White and 14% were Black, even though an estimated 33% of patients with lupus were White and 43% were Black.
Are there ways to fix this disparity? The topic is getting plenty of attention, and speakers at a July 21 online conference touted research projects that aim to boost the numbers of non-White participants in lupus trials.
So far there doesn’t seem to be anything like a magic bullet. Still, the stakes are high. “While race is a social construct, genetic polymorphisms as well as environmental and social differences may influence drugs, safety, and efficacy,” Joy Buie, PhD, MSCR, research director for the Lupus Foundation of America, said at the “Engaging Diverse Participants in Lupus Clinical Trials: The Path Forward” summit held by the American College of Rheumatology (ACR).
As African American patients explained, minority populations often don’t trust the medical system and feel burned by their lengthy struggles to get diagnosed. In some cases, they don’t have full faith in their clinicians and feel unheard.
In a video presentation developed as part of a federal education campaign, Shanelle Gabriel, a poet and musician diagnosed with lupus, described her first reaction when her physician suggested she join a clinical trial. “My first reaction was no. I know my history,” she said, apparently referring to the infamous Tuskegee study that withheld proper treatment from Black men with syphilis for decades. “As an African American woman, I was scared. I didn’t want to be a guinea pig.”
Stacey Kennedy-Conner, a Chicago-area patient and advocate, told the summit audience about how patients can feel that clinical trial information can add “an extra layer of confusion” to their experience. “There’s also the mentality of, ‘If it’s not broke, don’t fix it’: If this medication regimen is working, I don’t want anybody to touch me.”
Monique Gore-Massy, a New York City patient and advocate, added that there can be a perception that patients with lupus “are stuck at home in bed.” In reality, she said, “we have jobs, we have families. Think about that, and consider everything that you’re asking from us: Is this taking me away from my family? Am I going to have to take off work? There may be incentives, but is that worth me taking time off work that I may not get paid for? These are some of the realities that we have to look at in terms of the whole entire clinical trial process.”
It’s also important to keep patients informed of progress being made in trials, she said. “You don’t want to say you just felt like a number and then not get any kind of follow-up.”
In the big picture, “there has to be something that builds up the confidence of individuals so that they are more mindful to participate in these clinical trials,” said Aleta McLean, an Atlanta patient who was diagnosed with lupus 14 years ago.
Several researchers highlighted ongoing projects at the summit. The ACR, for example, has launched a $500,000 initiative called Training to Increase Minority Enrollment in Lupus Clinical Trials with Community Engagement (TIMELY). The federally funded project aims to evaluate whether training of health care professionals can boost clinical trial participation among Black and Hispanic patients.
“We hope to disseminate the results of our project to the scientific community through abstracts, manuscripts, presentations at national meetings,” said rheumatologist Saira Z. Sheikh, MD, of the University of North Carolina at Chapel Hill. “Overall, our goal is to establish new partnerships to support the TIMELY model and advance the education and engagement of providers and community health workers.”
Pamela Payne-Foster, MD, MPH, preventive medicine/public health physician at the University of Alabama College of Community Health Sciences, Tuscaloosa, spoke about the federally funded Deep South Health Equity Project, which is paying patients to take part in an online education program and attend an online regional conference.
Other efforts are underway. The Lupus Research Alliance and its clinical affiliate Lupus Therapeutics have launched two initiatives. One is a program called Project Change (Community-based Health Action Network to Generate Trial Participation and Eliminate Disparities), and the Diversity in Lupus Research Program aims to fund scientists’ work.
Will any of this work boost diversity in clinical trials? As one audience member noted in a Q&A session, health care disparities – and knowledge about them – are nothing new: “Why are we not able to narrow the gap?”
Rear Admiral Richardae Araojo, PharmD, MS, director of the FDA’s Office of Minority Health and Health Equity and associate commissioner for minority health, replied that waves of interest in disparities come and go. “That contributes to why we may not see solutions. But ultimately, there are a lot of people doing a lot of work trying to solve the issues.”
The summit was sponsored by Bristol-Myers Squibb, Genentech, and RemeGen.

FROM AN ACR CLINICAL TRIAL SUMMIT
Intermittent fasting vs. calorie counting for weight loss
BOSTON –
For the study, 57 overweight and obese participants with type 2 diabetes were randomly assigned to three different groups: The first group ate between noon and 8 p.m., the second was asked to reduce caloric intake by 25% of maintenance calories, and the third, a control group, continued eating normally.
The calorie-restriction group tracked intake on MyFitnessPal, an app that logs the calorie content of different foods. Both the intermittent-fasting and calorie-restriction groups were assigned a dietitian to help with adherence.
After 6 months, participants in the intermittent-fasting group lost about 4.3% of body weight – the equivalent of 10 pounds of weight loss for a person weighing 230 pounds – whereas participants in the calorie-restriction group lost about 2.5% of body weight.
The difference between the two groups was not significant, so one approach isn’t necessarily better than the other for weight loss.
“Let’s not think of this as an approach that’s better than calorie restriction,” William Yancy, MD, MHS, an internist and weight management specialist at Duke Lifestyle and Weight Management Center, Durham, N.C., said in an interview. “It’s an alternative approach to calorie restriction.”
Participants’ willingness to adhere to the diet likely accounted for the percentage difference between the groups, study author Vasiliki Pavlou, RDN, told this news organization. Ms. Pavlou presented the findings at the Nutrition 2023 conference.
“People that have type 2 diabetes, they’ve already been to the doctor, they’ve already been told to count calories,” said Ms. Pavlou, a doctoral student at the University of Illinois at Chicago. “There were many weeks where they came to us with nothing on MyFitnessPal and we’d have to encourage them to start tracking again.”
The intermittent-fasting group adhered to the eating time window 6 out of 7 days of the week, with a 1-hour grace period for the noon-to-8-p.m. window. In comparison, one-third of the calorie-restriction group didn’t stay within 200 calories of the goal, according to Ms. Pavlou.
That meant the fasting group cut about 100 calories more per day than the calorie-restriction group, which was reflected in their weight loss, Ms. Pavlou said.
A1c levels dropped by about 1% in both the intermittent-fasting and calorie-restriction groups – a meaningful decrease, said Dr. Yancy. “I think a 0.5% difference would have some clinical significance in terms of complications from diabetes,” he said. “So 1% would be even more clinically meaningful.”
However, fewer participants taking insulin in the calorie-restriction group could explain the difference, according to Ms. Pavlou. “Usually, when someone goes on insulin, their pancreas is already not functioning as well,” she said. “And it’s way harder to see improvements in their A1c and glycemic control.”
Up to 90% of people with type 2 diabetes are overweight or obese. Weight loss is one of the major components of type 2 diabetes care, according to the American Diabetes Association, and studies have shown that even a 5% reduction in body weight can reduce blood glucose concentration and A1c. Some studies suggest diabetes remission can occur after a 10% loss in body weight, but Dr. Yancy said it depends on the person.
“It depends on the individual, their metabolic situation, how long they’ve had diabetes, what kind of approach they’re following, maybe what medicines they’re taking,” Dr. Yancy said. “There’s a lot of different factors involved in remission.”
The study cohort generally had advanced diabetes and was taking a mix of medications, so the results might not be applicable to people with a more recent diabetes diagnosis, according to Ms. Pavlou.
Dr. Yancy said intermittent fasting could work well for the right person. The success of the approach could depend on a person’s eating habits and whether their meals usually fall outside the time-restricted window, or it could depend on how well a person follows rules, according to Dr. Yancy.
“Some people might not eat much after 8 o’clock, and some people might skip breakfast,” Dr. Yancy said. “And if that’s the case, then it’s not going to make a big impact on their weight probably.”
Medication is also an important consideration. Not eating can be dangerous for patients taking short-acting insulin or sulfonylureas, according to Dr. Yancy.
Ms. Pavlou said these findings show intermittent fasting is another option for patients with type 2 diabetes trying to lose weight. “If you’ve tried calorie counting, that’s not working for you or if you’re kind of burnt out, this is something else that you could try,” she said.
“We have a lot of patients that need to lose weight, and we have patients who respond differently to different approaches,” said Dr. Yancy. “So having various approaches is really valuable.”
The manuscript is currently under review at JAMA Internal Medicine, said Ms. Pavlou.

“Let’s not think of this as an approach that’s better than calorie restriction,” William Yancy, MD, MHS, an internist and weight management specialist at Duke Lifestyle and Weight Management Center, Durham, N.C., said in an interview. “It’s an alternative approach to calorie restriction.”
Participants’ willingness to adhere to the diet likely accounted for the percentage difference between the groups, study author Vasiliki Pavlou, RDN, told this news organization. Ms. Pavlou presented the findings at the Nutrition 2023 conference.
“People that have type 2 diabetes, they’ve already been to the doctor, they’ve already been told to count calories,” said Ms. Pavlou, a doctoral student at the University of Illinois at Chicago. “There were many weeks where they came to us with nothing on MyFitnessPal and we’d have to encourage them to start tracking again.”
The intermittent-fasting group adhered to the eating time window 6 out of 7 days of the week, with a 1-hour grace period for the noon-to-8-p.m. window. In comparison, one-third of the calorie-restriction group didn’t stay within 200 calories of the goal, according to Ms. Pavlou.
That meant the fasting group cut about 100 calories more per day than the calorie-restriction group, which was reflected in their weight loss, Ms. Pavlou said.
A1c levels dropped by about 1% in both the intermittent-fasting and calorie-restriction groups – a meaningful decrease, said Dr. Yancy. “I think a 0.5% difference would have some clinical significance in terms of complications from diabetes,” he said. “So 1% would be even more clinically meaningful.”
However, fewer participants taking insulin in the calorie-restriction group could explain the difference, according to Ms. Pavlou. “Usually, when someone goes on insulin, their pancreas is already not functioning as well,” she said. “And it’s way harder to see improvements in their A1c and glycemic control.”
Up to 90% of people with type 2 diabetes are overweight or obese. Weight loss is one of the major components of type 2 diabetes care, according to the American Diabetes Association, and studies have shown that even a 5% reduction in body weight can reduce blood glucose concentration and A1c. Some studies suggest diabetes remission can occur after a 10% loss in body weight, but Dr. Yancy said it depends on the person.
“It depends on the individual, their metabolic situation, how long they’ve had diabetes, what kind of approach they’re following, maybe what medicines they’re taking,” Dr. Yancy said. “There’s a lot of different factors involved in remission.”
The study cohort generally had advanced diabetes and was taking a mix of medications, so the results might not be applicable to people with a more recent diabetes diagnosis, according to Ms. Pavlou.
Dr. Yancy said intermittent fasting could work well for the right person. The success of the approach could depend on a person’s eating habits and whether their meals usually fall outside the time-restricted window, or it could depend on how well a person follows rules, according to Dr. Yancy.
“Some people might not eat much after 8 o’clock, and some people might skip breakfast,” Dr. Yancy said. “And if that’s the case, then it’s not going to make a big impact on their weight probably.”
Medication is also an important consideration. Not eating can be dangerous for patients taking short-acting insulin or sulfonylureas, according to Dr. Yancy.
Ms. Pavlou said these findings show intermittent fasting is another option for patients with type 2 diabetes trying to lose weight. “If you’ve tried calorie counting, that’s not working for you or if you’re kind of burnt out, this is something else that you could try,” she said.
“We have a lot of patients that need to lose weight, and we have patients who respond differently to different approaches,” said Dr. Yancy. “So having various approaches is really valuable.”
The manuscript is currently under review at JAMA Internal Medicine, said Ms. Pavlou.

Daily statin cuts cardiovascular risk in HIV
BRISBANE, AUSTRALIA – that show pitavastatin therapy is associated with a significantly lower risk of cardiovascular events than placebo.
“There was a significant 35% lower risk of major adverse cardiovascular events after a median follow-up of 5.1 years “ said Steven Grinspoon, MD, from Massachusetts General Hospital and Harvard Medical School in Boston, who presented the final analysis of data from the REPRIEVE trial at the International AIDS Society Conference on HIV Science.
The results were simultaneously published in the New England Journal of Medicine. The primary endpoint of major adverse cardiovascular events included a composite of outcomes that included cardiovascular death, stroke, myocardial infarction, hospitalization for unstable angina, and transient ischemic attack among those treated with pitavastatin, compared with placebo (95% confidence interval, 0.48-0.90; P = .002).
The REPRIEVE trial was halted earlier this year for efficacy after an interim analysis pointed to a significantly lower rate of cardiovascular events in the treatment group.
The international double-blind, placebo-controlled trial randomly assigned 7,769 people with HIV infection, who were at low to moderate risk of cardiovascular disease, to either 4 mg daily of pitavastatin calcium or placebo.
The secondary outcome – a composite of major cardiovascular events and all-cause mortality – also showed a significant 21% reduction in risk with pitavastatin treatment, compared with placebo (95% CI, 0.65-0.96).
Cardiovascular events in HIV
HIV infection is an independent risk factor for cardiovascular disease, Dr. Grinspoon pointed out, and those living with HIV have about double the risk of myocardial infarction and stroke, compared with the general population.
“There’s an unmet need for people living with HIV who have low to moderate traditional risk, for whom HIV is even considered a risk equivalent but for whom no primary prevention strategy has been tested in a large trial,” Dr. Grinspoon said during an interview.
Those enrolled in the study had a 10-year Atherosclerotic Cardiovascular Disease risk score ranging from 2.1% to 7%, with a median of 4.5%. While LDL cholesterol levels at baseline ranged from 87 to 128 mg/dL, the study showed a similar reduction in cardiovascular risk regardless of LDL.
“These are types of people who, if they came to the doctor’s office right now before REPRIEVE, they would largely be told your risk score is not really making you eligible for a statin,” Dr. Grinspoon said.
He explained that what is most interesting about the reduction in risk is that it was nearly twice what would be expected with LDL lowering, based on what has previously been seen in statin trials in non–HIV-positive populations.
“I think the data are suggesting that it’s certainly in part due to the reduction in LDL – that is very important – but it’s also due to other factors beyond changes in LDL,” Dr. Grinspoon said. He speculated that the statin could be affecting anti-inflammatory and immune pathways, and that this could account for some of the reduction in cardiovascular risk, but “those data are cooking, and they’re being analyzed as we speak.”
In a substudy analysis of REPRIEVE, Markella Zanni, MD, associate professor of medicine at Harvard Medical School and Massachusetts General Hospital, focused on the women in the clinical trial.
Women’s risk
In REPRIEVE, 31.1% of the study population were women. Dr. Zanni and her team investigated whether there are differences in the way HIV affects the risk of developing atherosclerotic cardiovascular disease in women, compared with men.
They found that women have both higher levels of inflammatory markers, such as interleukin-6, C-reactive protein, and D-dimer, but a lower prevalence of coronary artery plaques than men.
“This finding represents an interesting paradox given that high levels of select inflammatory markers have been associated with coronary artery plaque, both among women living with HIV and among men living with HIV,” Dr. Zanni explained.
She says the researchers were hoping to further explore whether inflammation is fueling the increased risk for atherosclerotic disease, and particularly the higher risk evident in women living with HIV, compared with men.
“Women living with HIV should discuss with their treating clinicians heart risks and possible prevention strategies, including statin therapy coupled with healthy lifestyle changes addressing modifiable, traditional metabolic risk factors” she said.
Time for primary prevention?
All patients in the study were on antiretroviral therapy and investigators report that pitavastatin does not interact with these medications. The median CD4 cell count was 621 cells/mm3, and 87.5% of participants had an HIV viral load below the lower limit of quantification.
Participants were enrolled from 12 countries including the United States, Spain, Brazil, South Africa, and Thailand, and around two-thirds were non-White. Individuals of South Asian ethnicity showed the biggest reduction in cardiovascular risk with pitavastatin treatment.
There was a 74% higher rate of muscle pain and weakness in the pitavastatin group – affecting 91 people in the treatment arm and 53 in the placebo arm – but the majority were low grade. The rate of rhabdomyolysis of grade 3 or above was lower in the statin group, with three cases, compared with four cases in the placebo group.
Commenting on the findings, Laura Waters, MD, a genitourinary and HIV medicine consultant at Central and North West London NHS Foundation Trust’s Mortimer Market Centre, said that, while HIV infection was considered a risk factor for cardiovascular disease, risk calculators don’t specifically adjust for HIV infection.
“Now that we’ve got effective HIV drugs and people can enjoy normal life expectancy, cardiovascular disease is a particular issue for people with HIV,” she said.
Dr. Waters, who was not involved with the study, suggested that people living with HIV should discuss the use of statins with their doctor, but she acknowledged there are some barriers to treatment in people living with HIV. “It’s another pill, and when it’s a borderline [decision] it is easy to say, ‘I have to think about it,’ ” she said, with the result that statin treatment is often deferred.
The REPRIEVE study was supported by grants from the National Institutes of Health, Kowa Pharmaceuticals America, Gilead Sciences, and ViiV Healthcare. Dr. Grinspoon declared institutional grants from National Institutes of Health, Kowa Pharmaceuticals America, Gilead Sciences, and ViiV Healthcare and consultancies unrelated to the study. Dr. Zanni reports no relevant financial relationships.

Oral tau inhibitor continues to show promise in Alzheimer’s
in the LUCIDITY phase 3 trial.
Blood concentrations of neurofilament light chain (NfL) showed a 93% reduction in change over 12 months in participants receiving HMTM at the target dose of 16 mg/day relative to the control group, which correlated significantly with a tau biomarker (p-tau 181) in blood and changes in cognitive test scores.
“This is the first tau aggregation inhibitor to reach the phase 3 stage of development and to produce results like this,” Claude Wischik, PhD, executive chairman of TauRx Therapeutics, which is developing the drug, noted in an interview.
“NfL is one of the best studied biomarkers in the business because it goes off the rails in a range of neurodegenerative disorders. In AD, it correlates with disease severity, and it tracks ongoing damage to neurons,” Dr. Wischik explained.
Oral HMTM was designed to reduce tau pathology in AD, and the noted changes in NfL concentration by HMTM indicate a “direct impact on disease pathology,” Dr. Wischik said.
The findings, from a prespecified blood biomarker analysis of the LUCIDITY phase 3 trial, were presented at the annual Alzheimer’s Association International Conference.
Support for tau inhibitor
Topline results from the LUCIDITY trial showed improvement in cognition over 18 months in participants with mild cognitive impairment (MCI) caused by AD who were treated with a 16-mg/day dose of HMTM.
However, in an odd twist, participants in the control group who received a low dose of methylthioninium chloride (MTC) also showed cognitive improvement.
As a result, HMTM 16 mg/day failed to reach its two primary endpoints – change from baseline on the Alzheimer’s Disease Assessment Scale–Cognitive Subscale (ADAS-Cog11) and the Alzheimer’s Disease Cooperative Study/Activities of Daily Living Inventory (ADCS-ADL23) – relative to the MTC control group.
That’s likely because treatment with MTC, which is a variant of HMTM, unexpectedly achieved blood levels of active drug above the threshold needed to produce a clinical effect.
For the prespecified biomarker analysis reported at AAIC 2023, baseline and 12-month NfL plasma levels were available in 161 of 185 participants receiving HMTM 16 mg/day, 38 of 48 receiving HMTM 8 mg/day and 136 of 185 receiving MTC 8 mg/week.
Blood concentrations of NfL showed a statistically significant 93% reduction in change over 12 months in participants receiving HMTM at a dose of 16 mg/day relative to the control group (P = .0278), Dr. Wischik reported.
In addition, the p-tau 181 increase over 12 months “reduced to zero” with HMTM 16 mg/day and there was significant correlation between change in NfL and p-tau 181 concentration, he noted.
NfL reductions were significantly correlated with change in ADAS-Cog11 (P = .0038) and whole brain volume (P = .0359) over 24 months.
‘Exciting’ biomarker data
Commenting on the new data in an interview, Christopher Weber, PhD, director of global science initiatives at the Alzheimer’s Association, said the phase 3 LUCIDITY results “suggest that HMTM could be a potential therapeutic for slowing down neurodegenerative processes in Alzheimer’s disease.”
“Plasma NfL is an interesting biomarker which is used more and more in clinical trials because it’s noninvasive, accessible, and can assist in diagnosing and monitoring the disease in the early stages. Elevated NfL levels suggest that neurons are being affected in the brain, which could indicate the presence or progression of Alzheimer’s disease,” Dr. Weber said in an interview.
He said the biomarker data from the LUCIDITY study are “exciting.”
“However, due to the relatively small sample size, we look forward to seeing additional research on HMTM in larger, and even more diverse cohorts to better understand the performance of this treatment and the role of NfL in Alzheimer’s disease,” Dr. Weber said.
Also providing outside perspective, Howard Fillit, MD, founding executive director of the Alzheimer’s Drug Discovery Foundation, noted that currently “there is a lot of effort in trying to address the abnormal tau that occurs in Alzheimer’s disease.”
The biomarker data from LUCIDITY show that HMTM “seems to markedly decrease the amount of NfL in plasma and there is some correlation with cognitive scores. The obvious unknown is whether these changes in plasma NfL will predict clinical benefit,” Dr. Fillit said in an interview.
“This is an oral drug that has a good safety profile, and the mechanism of action makes sense, but we need to see the clinical data,” Dr. Fillit said.
Final 2-year data from the LUCIDITY trial are expected to be released later in 2023.
In the United Kingdom, TauRx has entered an accelerated approval process for the drug, and the company said it plans to seek regulatory approval in the United States and Canada in 2023.
The study was funded by TauRx Therapeutics. Dr. Wischik is an employee of the University of Aberdeen (Scotland), and TauRx Therapeutics. Dr. Weber and Dr. Fillit reported no relevant financial relationships.

The findings, from a prespecified blood biomarker analysis of the LUCIDITY phase 3 trial, were presented at the annual Alzheimer’s Association International Conference.
Support for tau inhibitor
Topline results from the LUCIDITY trial showed improvement in cognition over 18 months in participants with mild cognitive impairment (MCI) caused by AD who were treated with a 16-mg/day dose of HMTM.
However, in an odd twist, participants in the control group who received a low dose of methylthioninium chloride (MTC) also showed cognitive improvement.
As a result, HMTM 16 mg/day failed to reach its two primary endpoints – change from baseline on the Alzheimer’s Disease Assessment Scale–Cognitive Subscale (ADAS-Cog11) and the Alzheimer’s Disease Cooperative Study/Activities of Daily Living Inventory (ADCS-ADL23) – relative to the MTC control group.
That’s likely because treatment with MTC, which is a variant of HMTM, unexpectedly achieved blood levels of active drug above the threshold needed to produce a clinical effect.
For the prespecified biomarker analysis reported at AAIC 2023, baseline and 12-month NfL plasma levels were available in 161 of 185 participants receiving HMTM 16 mg/day, 38 of 48 receiving HMTM 8 mg/day and 136 of 185 receiving MTC 8 mg/week.
Blood concentrations of NfL showed a statistically significant 93% reduction in change over 12 months in participants receiving HMTM at a dose of 16 mg/day relative to the control group (P = .0278), Dr. Wischik reported.
In addition, the p-tau 181 increase over 12 months “reduced to zero” with HMTM 16 mg/day and there was significant correlation between change in NfL and p-tau 181 concentration, he noted.
NfL reductions were significantly correlated with change in ADAS-Cog11 (P = .0038) and whole brain volume (P = .0359) over 24 months.
‘Exciting’ biomarker data
Commenting on the new data in an interview, Christopher Weber, PhD, director of global science initiatives at the Alzheimer’s Association, said the phase 3 LUCIDITY results “suggest that HMTM could be a potential therapeutic for slowing down neurodegenerative processes in Alzheimer’s disease.”
“Plasma NfL is an interesting biomarker which is used more and more in clinical trials because it’s noninvasive, accessible, and can assist in diagnosing and monitoring the disease in the early stages. Elevated NfL levels suggest that neurons are being affected in the brain, which could indicate the presence or progression of Alzheimer’s disease,” Dr. Weber said in an interview.
He said the biomarker data from the LUCIDITY study are “exciting.”
“However, due to the relatively small sample size, we look forward to seeing additional research on HMTM in larger, and even more diverse cohorts to better understand the performance of this treatment and the role of NfL in Alzheimer’s disease,” Dr. Weber said.
Also providing outside perspective, Howard Fillit, MD, founding executive director of the Alzheimer’s Drug Discovery Foundation, noted that currently “there is a lot of effort in trying to address the abnormal tau that occurs in Alzheimer’s disease.”
The biomarker data from LUCIDITY show that HMTM “seems to markedly decrease the amount of NfL in plasma and there is some correlation with cognitive scores. The obvious unknown is whether these changes in plasma NfL will predict clinical benefit,” Dr. Fillit said in an interview.
“This is an oral drug that has a good safety profile, and the mechanism of action makes sense, but we need to see the clinical data,” Dr. Fillit said.
Final 2-year data from the LUCIDITY trial are expected to be released later in 2023.
In the United Kingdom, TauRx has entered an accelerated approval process for the drug, and the company said it plans to seek regulatory approval in the United States and Canada in 2023.
The study was funded by TauRx Therapeutics. Dr. Wischik is an employee of the University of Aberdeen (Scotland), and TauRx Therapeutics. Dr. Weber and Dr. Fillit reported no relevant financial relationships.

Study examines pediatric skin biopsy trends at a tertiary care center
.
In addition, fewer biopsies were performed in the first 3 years of the global COVID-19 pandemic than in the previous 3 years.
These findings from a retrospective analysis were presented during a poster session at the annual meeting of the Society for Pediatric Dermatology. The analysis set out to evaluate which patients required biopsy, which skin conditions were sampled, and if practice patterns changed following the start of the COVID-19 pandemic.
“The work is important because very few pediatric patients, relative to adult patients seen in dermatology clinics, have a biopsy done,” Kelly M. Cordoro, MD, one of the study authors, told this news organization.
“Approximately 1%-4% of pediatric patients visiting a dermatology clinic will have a biopsy done as compared to 30%-50% of adult patients. Understanding what is being biopsied in children sheds light on the medical decision-making required to decide when a biopsy is necessary,” said Dr. Cordoro, chief of pediatric dermatology at UCSF.
For the study, the researchers retrospectively reviewed 1,196 biopsy specimens from 1,080 unique patients that were performed by pediatric dermatologists at UCSF from 2017 to 2022. Half of the patients were female, their mean age was 11.5 years, and they ranged in age from 1 day to 61 years. Nearly half of biopsies (47%) were performed in patients aged 12-18 years and one-quarter (25.6%) were performed in those aged 6-11 years. In the remaining biopsies, 6.6% came from patients younger than 1 year, 5.8% of those aged 1-2 years, 7.3% from those aged 3-5 years, and 3.9% each in those aged 19-21 years and in those older than 21 years.
The five most common biopsy results were compound nevus (99 biopsies), pyogenic granuloma (96), spongiotic dermatitis (57), intradermal nevus (53), and pilomatricoma (40).
The researchers identified 30 malignant diagnoses in 28 unique patients, most commonly mycosis fungoides (in 16 patients with a median age of 12.5 years), basal cell carcinoma (in 5 patients with a median age of 9 years), and dermatofibrosarcoma protuberans (in 4 patients with a median age of 2 years).
There was no significant sex-based difference in the number of biopsies performed at a given age (P = .47), but Dr. Cordoro and colleagues noted a statistically significant decrease in the number of biopsies during the pandemic compared with the 3 years prior to the pandemic (P = .04).
“There was a slight uptick in 2022, although it remains to be seen whether this trend will continue,” they wrote in their abstract. “While the most common diagnoses in the years leading up to – versus following the start of the pandemic – were similar, there was one clear outlier. The histopathologic diagnosis of pernio spiked in 2020, reflecting the ‘COVID toes’ phenomenon”.
In an interview, Dr. Cordoro said that growths and rashes in children of all ages can, and should, be biopsied, but special considerations are necessary depending on the patient’s age and context.
“Our data showed that neoplastic conditions were biopsied more often than inflammatory conditions, with an emphasis on lesions that required removal (such as pyogenic granuloma), raised concerns for atypia (nevi), or had implications for systemic management (such as Langerhans cell histiocytosis and graft-versus-host disease). Importantly, cutaneous malignancies in children are rare but do occur, and a high index of suspicion is required when approaching any child with a complex neoplasm or rash.”
Dr. Cordoro characterized the medical decision making and rationale for biopsying skin lesions and rashes in children as “a complex process that involves weighing the risks of the biopsy itself against the benefit of the information it will provide; shared decision-making with the caregivers, the patient (if age-appropriate), and other members of the health care team; age of the child and clinical context; and whether the biopsy can be done at the bedside or requires sedation.”
Based on the study results, Dr. Cordoro said, the rationale to proceed with a biopsy boils down to three main goals: To make or confirm a diagnosis, to make decisions about management, and/or the biopsy itself is therapeutic.
UCSF dermatopathology fellow Suzanne W. Birmingham, MD, performed the study in collaboration with Dr. Cordoro and UCSF dermatopathologist Thaddeus W. Mully, MD. Additional analyses of this data set are in progress. The researchers reported having no relevant financial disclosures.

What makes teens choose to use sunscreen?
a cornerstone of skin cancer prevention, according to results from a systematic review.
“We know that skin cancer is one of the most common malignancies in the world, and sun protection methods such as sunscreen make it highly preventable,” first author Carly R. Stevens, a student at Tulane University, New Orleans, said in an interview. “This study demonstrates the adolescent populations that are most vulnerable to sun damage and how we can help mitigate their risk of developing skin cancer through education methods, such as Sun Protection Outreach Teaching by Students.”
Ms. Stevens and coauthors presented the findings during a poster session at the annual meeting of the Society for Pediatric Dermatology.
To investigate predictors of sunscreen use among high school students, they searched PubMed, Embase, and Web of Science using the terms (“sunscreen” or “SPF” or “sun protection”) and (“high school” or “teen” or “teenager” or “adolescent”) and limited the analysis to English studies reporting data on sunscreen use in U.S. high school students up to November 2021.
A total of 20 studies were included in the final review. The study populations ranged in number from 208 to 24,645. Of 11 studies that examined gender, all showed increased sunscreen use in females compared with males. Of five studies that examined age, all showed increased sunscreen use in younger adolescents, compared with their older counterparts.
Of four studies that examined the role of ethnicity on sunscreen use, White students were more likely to use sunscreen, compared with their peers of other ethnicities. “This may be due to perceived sun sensitivity, as [these four studies] also showed increased sunscreen use in populations that believed were more susceptible to sun damage,” the researchers wrote in their abstract.
In other findings, two studies that examined perceived self-efficacy concluded that higher levels of sunscreen use correlated with higher self-efficacy, while four studies concluded that high school students were more likely to use sunscreen if their parents encouraged them the wear it or if the parent used it themselves.
“With 40%-50% of ultraviolet damage being done before the age of 20, it’s crucial that we find ways to educate adolescents on the importance of sunscreen use and target those populations who were found to rarely use sunscreen in our study,” Ms. Stevens said.
In one outreach program, Sun Protection Outreach Teaching by Students (SPOTS), medical students visit middle and high schools to educate them about the importance of practicing sun protection. The program began as a collaboration between Saint Louis University and Washington University in St. Louis, but has expanded nationwide. Ms. Stevens described SPOTS as “a great way for medical students to present the information to middle and high school students in a way that is engaging and interactive.”
