CARLSBAD, CALIF. – For the estimated 10 million wounds that clinicians treat in the United States each year resulting from surgical procedures, trauma, burns, and other causes, the best outcome is a scar, a fibrotic dermis with a flattened epidermis that contains no sweat glands, no pilosebaceous units, and impaired nerve function.

But what if the outcome was skin regeneration instead of scar formation? At the annual symposium of the California Society of Dermatology & Dermatologic Surgery, Philip O. Scumpia, MD, PhD, described the development of a biomaterial known as microporous annealed particle (MAP) hydrogel, which in preclinical studies has been shown to trigger the immune system leading to improved tissue repair and healthier, stronger skin.

“We’re preprogrammed to undergo scarring,” said Dr. Scumpia, associate professor of dermatology at the University of California, Los Angeles. “Tissue fibrosis is an evolutionary process” where a fibrotic matrix is deposited “as quickly as possible to close the gap caused by an injury,” he noted. “All of the cues in the normal wound healing process result in fibrosis, but we want to move from scarring to tissue regeneration. The goal is to make something that can shift from this evolutionary process, and it’s proven to be inherently difficult.”

Common approaches to wound treatment include simple and advanced dressings, negative pressure, and hyperbaric oxygen. For wounds that persist beyond 30 days, advanced treatment options include decellularized grafts such as placental membranes, amniotic membranes, and acellular dermal matrices. “There are also cellularized grafts such as dressings that contain neonatal dermal fibroblasts,” which are expensive, said Dr. Scumpia, director of dermatopathology at the West Los Angeles VA Medical Center. “There are also semi-synthetic grafts such as single or double layer dermal replacement templates and synthetic dermal substitutes in the form of sheets or foam. All of these can help with wound coverage and help chronic wounds close on their own.”

Meanwhile, tissue regeneration – or efforts to restore tissue to its original functionality – include growth factors, stem cells, or replacement extracellular matrix (skin substitutes), or a combination. “Bioengineered dressings and bioengineered skin substitutes have shown modest improvement in wound healing but not tissue regeneration,” Dr. Scumpia said. “At best, we can accelerate scar formation and close the wound quicker, but nothing has been shown to regenerate tissue.”

Approaches to skin regeneration

Studies from the embryology literature have helped researchers develop better approaches to skin regeneration. For example, fetal skin heals without scarring when injured. “Hairs form from placodes, then sebaceous glands form, and fibroblasts that are part of the papillary mesenchymal body expressing special factors such as engrailed or CRABP1 drive hair follicle formation,” he said. “Many studies have shown that sonic hedgehog signaling, and Wnt/beta-catenin signaling can play a role in the development of new hair follicles. Also, fibroblasts in the dermis can drive hair follicle formation.”

Researchers are also learning about tissue regeneration from mouse models. For example, African spiny mice have been shown to heal regeneratively. “If you make wounds large enough on lab mice, the center heals regeneratively,” Dr. Scumpia said. “What’s interesting is that these same signals are present in embryonic hair follicle development. Why is this important? Who wants a hairy scar? It’s an organized structure that develops in the wound. That can help us understand what we need to put in so that our body regenerates on its own. In mouse models, the immune system has been shown to play a role in regeneration.”

Expanding on initial work conducted at UCLA, Dr. Scumpia and his colleagues founded San Diego-based Tempo Therapeutics, which is commercializing the MAP hydrogel to mimic the natural porosity and stiffness of skin. They sought to develop a new biomaterial, he said, noting that “the skin is porous on a microscale level, allowing cells to infiltrate different areas.” And the problem with existing biomaterials “is that they don’t incorporate into the skin very well,” he explained. “They’re usually stiff and rubbery and can cause a foreign body reaction, which can result in fibrous encapsulation and inflammation.”

The MAP hydrogel is composed of randomly packed “microsphere building blocks,” including an amino acid that promotes an immune response. When injected into a wound, the hydrogel forms a porous matrix in the tissue. Surface annealing locks in porosity and tissue grows into porous spaces, which avoids scar formation pathways and enables critical organs to regain function.

During in vivo tests, researchers observed decreases in inflammation compared with traditional hydrogels in the first 48 hours. “In mouse models, we found that if you inject in a hydrogel that has no porosity, the body tries to spit it out, and you have an immune reaction,” Dr. Scumpia said. “But when we used the MAP hydrogel, we found that cells can migrate through it, which allows wounds to heal quicker. When we added an antigen in the hydrogel trying to allow the hydrogel to degrade slower, it actually degraded more rapidly, but we found that new hair follicles formed in the center of these wounds, a hallmark of skin regeneration. My lab has been studying why this occurs and trying to use this to our advantage in other models.”

In an unpublished mouse burn wound model study, he and his colleagues excised a wound, but it never healed with regeneration in the center. “We don’t understand why,” he said. But when the researchers used the MAP gel in wounds of hairless mice, they observed the formation of sebaceous glands and hair follicles over the wound beds. “It’s an exciting finding to see hair follicles develop in the center of a wound,” Dr. Scumpia said. He noted that to date, use of the MAP hydrogel has demonstrated tissue regeneration in some of the 27 veterinary cases that have been performed, including for wounds following traumatic injuries or following tumor resections on paws that allowed the pets to avoid amputation.

Clinical trials planned

The first clinical trials of the MAP hydrogel are planned for treating complex diabetic wounds in early 2024 but will likely expand to other difficult-to-treat wounds, including venous stasis ulcers, decubitus ulcers, and use following large surgical resections. Dr. Scumpia and colleagues will also examine the regenerative biomaterial for tissue aesthetics, including dermal and deep tissue filler applications. The next steps in his laboratory, he said, are to combine biomaterials with stem cells, immune factors, or small molecular activators/inhibitors to improve sweat gland, nerve, or hair follicle regeneration.

Dr. Scumpia disclosed that he is a cofounder and shareholder in Tempo Therapeutics. He has also received grant support from the National Institutes of Health, Department of Veteran Affairs, and the LEO Foundation.

CARLSBAD, CALIF. – In the opinion of Swati Kannan, MD, deciding whether or not to establish a presence on social media starts with a gut-check about your intentions.

“Why use it?” Dr. Kannan, a dermatologist and Mohs surgeon at the University of California, San Diego, asked attendees at the annual symposium of the California Society of Dermatology & Dermatologic Surgery. “Isn’t being an MD or DO enough? Not anymore. Social media allows you to reach a much larger audience. You’re able to market yourself and market dermatology. It establishes us as the authority in dermatology [topics], showcases our expertise and knowledge, and differentiates us from other nondermatology providers.”

Dr. Swati Kannan

Her favorite part about using Instagram and other social media platforms, she said, is connecting with other dermatologists and other specialists. “I’ve learned a lot from communicating with other dermatologists on different platforms, not just for social media but for changing how I practice as well.”

Dr. Kannan offered the following tips and considerations for building and maintaining a presence on social media:

Know the demographics of your practice and your target audience. In general, individuals in their 20s have a presence on many platforms, mainly TikTok for entertainment. Those in their 30s and 40s mainly use Facebook, Instagram, and YouTube, and those in their 40s-60s primarily use Facebook and YouTube. “Men tend to use YouTube, Twitter (X), Reddit, and LinkedIn, while women prefer more photo or video content platforms like Instagram, TikTok, and Facebook,” she said. In addition, knowing your target audience will help select which social media platforms to be active on.

Think about your goal. Is it a side hustle? Is it to raise awareness of various dermatologic conditions? Is it to grow your business? “Knowing this goal will help you determine how much time you’re going to commit to it.”

Do you have the time? To be effective, being active on social media can take 10-15 hours a week, especially for beginners, “so it’s like another job,” she said.

Devise a social media strategy. “Ideally, pick one to three social media platforms that you are going to be active on,” Dr. Kannan advised. “I’m active on Instagram and YouTube, and I cross-post on TikTok and Facebook. That means when I’m making content, it’s geared toward the audience on Instagram. If it hits a few people on TikTok, that’s fine, too, but the TikTok audience is not my target.”

Stick to a posting schedule. Ideally, post three to five times per week.

Create a content strategy. This includes a variety of photos, diagrams, videos, “and you want to use relevant hashtags,” she said.

Find your niche and style. This comes with time. If you specialize in a specific dermatologic condition such as psoriasis, hair loss, or vitiligo, emphasize that in your content.

Find your voice. This also comes with time. But be a professional version of yourself.

Have a plan for how to handle complaints or bad comments. “Avoid posting content that would make you a target,” she advised. “When I get a rude comment, I delete it. If the comment is racist or sexist, I will report it.”

Learn how to review the stats on your accounts. This will provide information on which posts or videos are being well received, which can serve as the basis of creating content that’s similar going forward.

Follow certain social media strategists. This can help grow followers and learn how to find trending audio or music to accompany your content. On Instagram, for example, Dr. Kannan follows @creators and @instagramforbusiness. On YouTube, she follows the Think Media channel.

Avoid posting content that would make you a target. Limit photos about partying/alcohol consumption or anything considered unprofessional. “If you can’t say it or do it in front of a patient, then you shouldn’t post it on your professional social media page,” she said.

Protect yourself. Don’t provide individual medical advice. “All of my home pages contain the statement, ‘this page is not for medical advice,’” Dr. Kannan said. “Get photo and video consent from all patients, even if you’re posting a zoomed-in version of their face. Deidentify patients as much as possible, and watermark your before and after photos and videos so that they’re not easily used by others.”

Be consistent and patient as you engage on social media platforms. Being a good digital citizen includes networking with other creators by liking and commenting on their posts, and responding to and liking comments that people make to your posts. “Remember: it’s not just about the number of followers, but also about engagement,” she said.

Dr. Kannan reported having no relevant disclosures.

When Haley Naik, MD, joined the University of California, San Francisco, as a dermatologist in 2015, she was struck by the dearth of data in the medical literature about hidradenitis suppurativa (HS).

“For decades there were no datasets to begin to understand HS – its clinical course, how patients respond to medications, and how quality of life improves for patients with therapy,” Dr. Naik, who directs the HS program at UCSF, said in an interview. Inspired to improve the bleak HS knowledge landscape, she began to systematically collect information from HS patient visits, “to try to better understand how treatments were helping them or not and also to better understand their quality-of-life impact,” she said. “This also facilitated research in HS, but over time it became clear that there was a growing need for a larger effort.”

But in 2020, Dr. Naik teamed up with investigative dermatologist Michelle Lowes, MBBS, PhD, to launch The Hidradenitis Suppurativa Prospective Observational Registry and Biospecimen Repository (HS PROGRESS), a national multicenter study designed to prospectively collect high-quality longitudinal clinical and biological data on patients with HS across major academic institutions and to care for HS patients. To date, more than 500 patients are enrolled at 12 participating sites, and 4 more sites plan to join the consortium by the end of 2023. The goal is to enroll a total of 8,000 patients, which will make it the largest dataset of its kind.

“Each site investigator is a physician who specializes in taking care of HS patients,” said Dr. Naik, who is the study’s principal investigator. “These are people who are conducting active research in various aspects of HS, and they’re trusted members of the medical community.”

She highlighted the three main objectives of HS PROGRESS. The first objective is to develop a longitudinal cohort of HS patients so that investigators can understand the clinical course of HS and effectiveness of treatments. The second is to collect biospecimens from patients with HS for translational studies “that can help to drive drug development, help us identify biomarkers that can help us predict disease course and predict patient response to therapies, so we know exactly what to give them,” she explained. The third objective is to provide patients with HS with the opportunity to be recruited for clinical trials, “so they have access to cutting-edge therapies and know what’s happening in this space.”

The goal of collecting biospecimens is to provide them to multiple investigators to improve the understanding of HS biology and treatment. “Our thought is to apply next generation techniques to these biospecimens to get metagenomic, transcriptomic, and genomic data to better understand HS biology so that we can identify targets for novel therapy,” Dr. Naik said.

Although HS is estimated to affect 1% of Western populations, the tumor necrosis alpha (TNF)-inhibitor adalimumab remains the only Food and Drug Administration-approved therapy for the condition.

However, Dr. Naik said that there are many promising drugs on the horizon for HS, especially interleukin (IL)-17 inhibitors. “One of the most exciting things about these drugs is that they set the bar higher for what we can expect out of therapies for HS, such as reporting a HiSCR (HS Clinical Response) score 75, which is the equivalent of 75% improvement in inflammatory HS lesions without an increase in draining tunnels,” she said. “This is well beyond what adalimumab had demonstrated in landmark trials in 2015. The safety profile on IL-17 inhibitors looks great, too.”

JAK inhibitors also hold promise for HS. “It’s going to be key to see how these drugs perform in the real-world setting in our average HS patients who may have comorbidities,” Dr. Naik said. “This is where an effort like HS PROGRESS will carry weight, because in a dataset like this, we’re going to be able to ask questions like, is there a class of drugs that works better for one specific phenotype of HS, or for patients who have a younger age of onset, or who are earlier in their disease course? These are questions we can’t ask in the context of a clinical trial, but we can ask in the context of real-world data from many practices.”

In addition to USCF, the 11 study locations participating in HS PROGRESS are the University of North Carolina at Chapel Hill; Mayo Clinic; Penn State University, Hershey; University of Virginia, Charlottesville; Washington University in St. Louis; University of Southern California, Los Angeles; Henry Ford Health, Detroit; University of Minnesota; University of Pennsylvania, Philadelphia; Duke University, Durham, N.C.; and University of Miami.

Dr. Naik disclosed that she has received grant support from AbbVie; consulting fees from 23andme, AbbVie, Aristea Therapeutics, Nimbus Therapeutics, Medscape, Sonoma Biotherapeutics, DAVA Oncology, Boehringer Ingelheim, UCB, and Novartis; and investigator fees from Pfizer; and holds shares in Radera. She is also an associate editor for JAMA Dermatology and a board member of the Hidradenitis Suppurativa Foundation.

When Haley Naik, MD, joined the University of California, San Francisco, as a dermatologist in 2015, she was struck by the dearth of data in the medical literature about hidradenitis suppurativa (HS).

“For decades there were no datasets to begin to understand HS – its clinical course, how patients respond to medications, and how quality of life improves for patients with therapy,” Dr. Naik, who directs the HS program at UCSF, said in an interview. Inspired to improve the bleak HS knowledge landscape, she began to systematically collect information from HS patient visits, “to try to better understand how treatments were helping them or not and also to better understand their quality-of-life impact,” she said. “This also facilitated research in HS, but over time it became clear that there was a growing need for a larger effort.”

But in 2020, Dr. Naik teamed up with investigative dermatologist Michelle Lowes, MBBS, PhD, to launch The Hidradenitis Suppurativa Prospective Observational Registry and Biospecimen Repository (HS PROGRESS), a national multicenter study designed to prospectively collect high-quality longitudinal clinical and biological data on patients with HS across major academic institutions and to care for HS patients. To date, more than 500 patients are enrolled at 12 participating sites, and 4 more sites plan to join the consortium by the end of 2023. The goal is to enroll a total of 8,000 patients, which will make it the largest dataset of its kind.

“Each site investigator is a physician who specializes in taking care of HS patients,” said Dr. Naik, who is the study’s principal investigator. “These are people who are conducting active research in various aspects of HS, and they’re trusted members of the medical community.”

She highlighted the three main objectives of HS PROGRESS. The first objective is to develop a longitudinal cohort of HS patients so that investigators can understand the clinical course of HS and effectiveness of treatments. The second is to collect biospecimens from patients with HS for translational studies “that can help to drive drug development, help us identify biomarkers that can help us predict disease course and predict patient response to therapies, so we know exactly what to give them,” she explained. The third objective is to provide patients with HS with the opportunity to be recruited for clinical trials, “so they have access to cutting-edge therapies and know what’s happening in this space.”

Vitamin B6, vitamin D, green tea, and probiotics are among the oral nutraceuticals that may benefit patients with acne, results from a systematic literature review suggest.

“While many topical and systemic prescription options are available for the treatment of acne, some patients may be interested in natural and complementary therapies as either an adjunctive or an alternative to prescription medications,” researchers led by John S. Barbieri, MD, MBA, of the department of dermatology at Brigham and Women’s Hospital, Boston, wrote in their study, which was published online in JAMA Dermatology. The researchers defined nutraceuticals as products derived from food sources that provide both nutritional and medicinal benefits, such as vitamins, dietary supplements, and herbal products. “Although patients may be interested in nutraceuticals as a potential treatment option for acne, there is uncertainty regarding the efficacy and safety of these products,” they wrote.

For the systematic review, they searched the PubMed, Embase, Cochrane Central Register of Controlled Trials, and Web of Science databases from inception through January 30, 2023, to identify randomized clinical trials that evaluated oral nutraceutical interventions such as vitamins and minerals, botanical extracts, prebiotics, and probiotics in individuals with acne. They extracted clinician-reported outcomes, patient-reported outcomes, and adverse events from the included studies, and used the Cochrane Risk of Bias checklist tool to assess the quality of evidence in randomized clinical trials. Based on this tool, they used Agency for Healthcare Research and Quality standards to categorize the articles as good, fair, or poor quality.

The search yielded 42 unique studies with 3,346 participants. Of these 42 studies, 27 were considered poor quality, 11 were considered fair quality, and 4 were considered good quality. The good-quality studies separately evaluated four interventions: vitamin D, green tea extract, probiotics, and cheongsangbangpoong-tang, an herbal formula approved for use in acne by the Korea Food and Drug Administration.

The 11 fair-quality studies suggested potential effectiveness for pantothenic acid (vitamin B5), the fatty acids omega-3 (eicosapentaenoic acid [EPA] and/or docosahexaenoic acid [DHA]) and omega-6 (gamma-linoleic acid), and probiotics.

Zinc was the most studied nutraceutical identified in the review, but “there was substantial heterogeneity in the results, with only slightly greater than one-half of studies finding zinc to be efficacious,” the authors noted. “Studies using higher doses more often found zinc to be efficacious,” they said, adding that zinc “had the highest rate of adverse effect reporting of any nutraceuticals assessed in this review.”

Dr. Barbieri and colleagues acknowledged limitations of their analysis, including the fact that few of the nutraceuticals considered to have good or fair evidence for their use were evaluated in more than one study. “In addition, some studies had inconsistent results depending on the outcome measure assessed,” they wrote. “For instance, although green tea extract led to statistically significant improvements in lesion counts, it did not result in statistically significant improvements in quality of life, suggesting the observed lesion count differences may not be clinically meaningful to patients.”

And while probiotics had the most studies supporting their efficacy, they were generally of very small sample size.

Dr. Jonette Keri

Asked to comment on the study, Jonette Keri, MD, PhD, a dermatologist who directs the Acne and Rosacea Treatment Center at the University of Miami, who was not involved with the study, said that while the review was exhaustive, more research is needed to better determine the efficacy and side effects of the products studied. “The real strength of this wonderful review is now we have all of this information in one place, and this will serve as a great patient care resource,” she told this news organization.

Dr. Barbieri reported personal fees from Dexcel Pharma for consulting outside the submitted work. Dr. Keri disclosed that she is a consultant for L’Oréal.

TOPLINE:

Adolescents with atopic dermatitis (AD) experience bullying significantly more often than their peers without AD.

METHODOLOGY:

• Adolescents with AD have reported appearance-based bullying.
• To evaluate the association between AD and the prevalence and frequency of bullying, researchers analyzed cross-sectional data from adult caregivers of U.S. adolescents aged 12-17 years who participated in the 2021 National Health Interview Survey.
• Logistic regression and ordinal logistic regression were used to compare the prevalence of experiencing one or more bullying encounters during the previous 12 months and the frequency of bullying between adolescents with and those without AD.

TAKEAWAY:

• A total of 3,207 adolescents were included in the analysis. The mean age of the participants was 14.5 years, and 11.9% currently had AD. The prevalence of experiencing bullying was significantly higher among adolescents with AD, compared with those without AD (33.2% vs. 19%; P < .001), as was the prevalence of cyberbullying (9.1% vs. 5.8%; P = .04).
• Following adjustment for demographics and atopic comorbidities, adolescents with AD were at increased odds of bullying, compared with their peers without AD (adjusted odds ratio, 1.99; 95% confidence interval, 1.45-2.73).
• Following adjustment for demographics, adolescents with AD were also at increased odds of cyberbullying, compared with their peers without AD (AOR, 1.65; 95% CI, 1.04-2.62), but no association was observed following adjustment for atopic comorbidities (AOR, 1.27; 95% CI, 0.82-1.96).
• Following ordinal logistic regression that was adjusted for demographics and atopic comorbidities, adolescents with AD were at greater odds of being bullied at a higher frequency, compared with their peers without AD (AOR, 1.97; 95% CI, 1.44-2.68).

IN PRACTICE:

“Larger, future studies using clinical AD diagnoses and adolescent self-report can advance understanding of bullying and AD,” the researchers wrote. “Clinicians, families, and schools should address and monitor bullying among adolescents.”

SOURCE:

Howa Yeung, MD, of the department of dermatology at Emory University School of Medicine, Atlanta, led the research. The study was published online  in JAMA Dermatology.

LIMITATIONS:

Limitations include the study’s cross-sectional design. In addition, the investigators could not directly attribute bullying to skin-specific findings, and it was a caregiver report.

DISCLOSURES:

The study was supported by grants from the National Institutes of Health and the National Institute of Arthritis and Musculoskeletal and Skin Diseases. One of the authors, Joy Wan, MD, received grants from Pfizer and personal fees from Janssen and Sun Pharmaceuticals outside of the submitted work.

WASHINGTON – The entire video clip is just 15 seconds — 15 seconds that went viral and temporarily upended the entire life and disrupted the medical practice of Nicole Baldwin, MD, a pediatrician in Cincinnati, Ohio, in January 2020. At the annual meeting of the American Academy of Pediatrics, Dr. Baldwin told attendees how her pro-vaccine TikTok video led a horde of anti-vaccine activists to swarm her social media profiles across multiple platforms, leave one-star reviews with false stories about her medical practice on various doctor review sites, and personally threaten her.

The initial response to the video was positive, with 50,000 views in the first 24 hours after the video was posted and more than 1.5 million views the next day. But 2 days after the video was posted, an organized attack that originated on Facebook required Dr. Baldwin to enlist the help of 16 volunteers, working 24/7 for a week, to help ban and block more than 6,000 users on Facebook, Instagram, and TikTok. Just 4 days after she’d posted the video, Dr. Baldwin was reporting personal threats to the police and had begun contacting sites such as Yelp, Google, Healthgrades, Vitals, RateMDs, and WebMD so they could start removing false reviews about her practice.

Today, years after those 2 exhausting, intense weeks of attacks, Dr. Baldwin has found two silver linings in the experience: More people have found her profiles, allowing her to share evidence-based information with an even wider audience, and she can now help other physicians protect themselves and reduce the risk of similar attacks, or at least know how to respond to them if they occur. Dr. Baldwin shared a wealth of tips and resources during her lecture to help pediatricians prepare ahead for the possibility that they will be targeted next, whether the issue is vaccines or another topic.
 

Online risks and benefits

A Pew survey of U.S. adults in September 2020 found that 41% have personally experienced online harassment, including a quarter of Americans who have experienced severe harassment. More than half of respondents said online harassment and bullying is a major problem – and that was a poll of the entire population, not even just physicians and scientists.

“Now, these numbers would be higher,” Dr. Baldwin said. “A lot has changed in the past 3 years, and the landscape is very different.”

The pandemic contributed to those changes to the landscape, including an increase in harassment of doctors and researchers. A June 2023 study revealed that two-thirds of 359 respondents in an online survey reported harassment on social media, a substantial number even after accounting for selection bias in the individuals who chose to respond to the survey. Although most of the attacks (88%) resulted from the respondent’s advocacy online, nearly half the attacks (45%) were gender based, 27% were based on race/ethnicity, and 13% were based on sexual orientation.

While hateful comments are likely the most common type of online harassment, other types can involve sharing or tagging your profile, creating fake profiles to misrepresent you, fake reviews of your practice, harassing phone calls and hate mail at your office, and doxxing, in which someone online widely shares your personal address, phone number, email, or other contact information.

Despite the risks of all these forms of harassment, Dr. Baldwin emphasized the value of doctors having a social media presence given how much misinformation thrives online. For example, a recent report from the Kaiser Family Foundation revealed how many people weren’t sure whether certain health misinformation claims were true or false. Barely a third of people were sure that COVID-19 vaccines had not caused thousands of deaths in healthy people, and only 22% of people were sure that ivermectin is not an effective treatment for COVID.

“There is so much that we need to be doing and working in these spaces to put evidence-based content out there so that people are not finding all of this crap from everybody else,” Dr. Baldwin said. Having an online presence is particularly important given that the public still has high levels of trust in their doctors, she added.

“They trust their physician, and you may not be their physician online, but I will tell you from experience, when you build a community of followers, you become that trusted source of information for them, and it is so important,” Dr. Baldwin said. “There is room for everybody in this space, and we need all of you.”
 

Proactive steps for protection

Dr. Baldwin then went through the details of what people should do now to make things easier in the event of an attack later. “The best defense is a good offense,” Dr. Baldwin said, “so make sure all of your accounts are secure.”

She recommended the following steps:

• Use two-factor authentication for all of your logins.
• Use strong, unique passwords for all of your logins.
• Use strong privacy settings on all of your private social media profiles, such as making sure photos are not visible on your personal Facebook account.
• Claim your Google profile and Yelp business profile.
• Claim your doctor and/or business profile on all of the medical review sites where you have one, including Google, Healthgrades, Vitals, RateMDs, and WebMD.

For doctors who are attacked specifically because of pro-vaccine advocacy, Dr. Baldwin recommended contacting Shots Heard Round The World, a site that was created by a physician whose practice was attacked by anti-vaccine activists. The site also has a toolkit that anyone can download for tips on preparing ahead for possible attacks and what to do if you are attacked.

Dr. Baldwin then reviewed how to set up different social media profiles to automatically hide certain comments, including comments with words commonly used by online harassers and trolls:

• Sheep
• Sheeple
• Pharma
• Shill
• Die
• Psychopath
• Clown
• Various curse words
• The clown emoji

In Instagram, go to “Settings and privacy —> Hidden Words” for options on hiding offensive comments and messages and for managing custom words and phrases that should be automatically hidden.

On Facebook, go to “Professional dashboard —> Moderation Assist,” where you can add or edit criteria to automatically hide comments on your Facebook page. In addition to hiding comments with certain keywords, you can hide comments from new accounts, accounts without profile photos, or accounts with no friends or followers.

On TikTok, click the three-line menu icon in the upper right, and choose “Privacy —> Comments —> Filter keywords.”

On the platform formerly known as Twitter, go to “Settings and privacy —> Privacy and safety —> Mute and block —> Muted words.”

On YouTube, under “Manage your community & comments,” select “Learn about comment settings.”

Dr. Baldwin did not discourage doctors from posting about controversial topics, but she said it’s important to know what they are so that you can be prepared for the possibility that a post about one of these topics could lead to online harassment. These hot button topics include vaccines, firearm safety, gender-affirming care, reproductive choice, safe sleep/bedsharing, breastfeeding, and COVID masks.

If you do post on one of these and suspect it could result in harassment, Dr. Baldwin recommends turning on your notifications so you know when attacks begin, alerting your office and call center staff if you think they might receive calls, and, when possible, post your content at a time when you’re more likely to be able to monitor the post. She acknowledged that this last tip isn’t always relevant since attacks can take a few days to start or gain steam.
 

Defending yourself in an attack

Even after taking all these precautions, it’s not possible to altogether prevent an attack from happening, so Dr. Baldwin provided suggestions on what to do if one occurs, starting with taking a deep breath.

“If you are attacked, first of all, please remain calm, which is a lot easier said than done,” she said. “But know that this too shall pass. These things do come to an end.”

She advises you to get help if you need it, enlisting friends or colleagues to help with moderation and banning/blocking. If necessary, alert your employer to the attack, as attackers may contact your employer. Some people may opt to turn off comments on their post, but doing so “is a really personal decision,” she said. It’s okay to turn off comments if you don’t have the bandwidth or help to deal with them.

However, Dr. Baldwin said she never turns off comments because she wants to be able to ban and block people to reduce the likelihood of a future attack from them, and each comment brings the post higher in the algorithm so that more people are able to see the original content. “So sometimes these things are actually a blessing in disguise,” she said.

If you do have comments turned on, take screenshots of the most egregious or threatening ones and then report them and ban/block them. The screenshots are evidence since blocking will remove the comment.

“Take breaks when you need to,” she said. “Don’t stay up all night” since there are only going to be more in the morning, and if you’re using keywords to help hide many of these comments, that will hide them from your followers while you’re away. She also advised monitoring your online reviews at doctor/practice review sites so you know whether you’re receiving spurious reviews that need to be removed.

Dr. Baldwin also addressed how to handle trolls, the people online who intentionally antagonize others with inflammatory, irrelevant, offensive, or otherwise disruptive comments or content. The No. 1 rule is not to engage – “Don’t feed the trolls” – but Dr. Baldwin acknowledged that she can find that difficult sometimes. So she uses kindness or humor to defuse them or calls them out on their inaccurate information and then thanks them for their engagement. Don’t forget that you are in charge of your own page, so any complaints about “censorship” or infringing “free speech” aren’t relevant.

If the comments are growing out of control and you’re unable to manage them, multiple social media platforms have options for limited interactions or who can comment on your page.

On Instagram under “Settings and privacy,” check out “Limited interactions,” “Comments —> Allow comments from,” and “Tags and mentions” to see ways you can limit who is able to comment, tag or mention your account. If you need a complete break, you can turn off commenting by clicking the three dots in the upper right corner of the post, or make your account temporarily private under “Settings and privacy —> Account privacy.”

On Facebook, click the three dots in the upper right corner of posts to select “Who can comment on your post?” Also, under “Settings —> Privacy —> Your Activity,” you can adjust who sees your future posts. Again, if things are out of control, you can temporarily deactivate your page under “Settings —> Privacy —> Facebook Page information.”

On TikTok, click the three lines in the upper right corner of your profile and select “Privacy —> Comments” to adjust who can comment and to filter comments. Again, you can make your account private under “Settings and privacy —> Privacy —> Private account.”

On the platform formerly known as Twitter, click the three dots in the upper right corner of the tweet to change who can reply to the tweet. If you select “Only people you mentioned,” then no one can reply if you did not mention anyone. You can control tagging under “Settings and privacy —> Privacy and safety —> Audience and tagging.”

If you or your practice receive false reviews on review sites, report the reviews and alert the rating site when you can. In the meantime, lock down your private social media accounts and ensure that no photos of your family are publicly available.
 

Social media self-care

Dr. Baldwin acknowledged that experiencing a social media attack can be intense and even frightening, but it’s rare and outweighed by the “hundreds and hundreds and hundreds of positive comments all the time.” She also reminded attendees that being on social media doesn’t mean being there all the time.

“Over time, my use of social media has certainly changed. It ebbs and flows,” she said. “There are times when I have a lot of bandwidth and I’m posting a lot, and then I actually have had some struggles with my own mental health, with some anxiety and mild depression, so I took a break from social media for a while. When I came back, I posted about my mental health struggles, and you wouldn’t believe how many people were so appreciative of that.”
 

Accurate information from a trusted source

Ultimately, Dr. Baldwin sees her work online as an extension of her work educating patients.

“This is where our patients are. They are in your office for maybe 10-15 minutes maybe once a year, but they are on these platforms every single day for hours,” she said. “They need to see this information from medical professionals because there are random people out there that are telling them [misinformation].”

Elizabeth Murray, DO, MBA, an emergency medicine pediatrician at Golisano Children’s Hospital at the University of Rochester, agreed that there’s substantial value in doctors sharing accurate information online.

“Disinformation and misinformation is rampant, and at the end of the day, we know the facts,” Dr. Murray said. “We know what parents want to hear and what they want to learn about, so we need to share that information and get the facts out there.”

Dr. Murray found the session very helpful because there’s so much to learn across different social media platforms and it can feel overwhelming if you aren’t familiar with the tools.

“Social media is always going to be here. We need to learn to live with all of these platforms,” Dr. Murray said. “That’s a skill set. We need to learn the skills and teach our kids the skill set. You never really know what you might put out there that, in your mind is innocent or very science-based, that for whatever reason somebody might take issue with. You might as well be ready because we’re all about prevention in pediatrics.”

There were no funders for the presentation. Dr. Baldwin and Dr. Murray had no disclosures.

WASHINGTON – The entire video clip is just 15 seconds — 15 seconds that went viral and temporarily upended the entire life and disrupted the medical practice of Nicole Baldwin, MD, a pediatrician in Cincinnati, Ohio, in January 2020. At the annual meeting of the American Academy of Pediatrics, Dr. Baldwin told attendees how her pro-vaccine TikTok video led a horde of anti-vaccine activists to swarm her social media profiles across multiple platforms, leave one-star reviews with false stories about her medical practice on various doctor review sites, and personally threaten her.

The initial response to the video was positive, with 50,000 views in the first 24 hours after the video was posted and more than 1.5 million views the next day. But 2 days after the video was posted, an organized attack that originated on Facebook required Dr. Baldwin to enlist the help of 16 volunteers, working 24/7 for a week, to help ban and block more than 6,000 users on Facebook, Instagram, and TikTok. Just 4 days after she’d posted the video, Dr. Baldwin was reporting personal threats to the police and had begun contacting sites such as Yelp, Google, Healthgrades, Vitals, RateMDs, and WebMD so they could start removing false reviews about her practice.

Today, years after those 2 exhausting, intense weeks of attacks, Dr. Baldwin has found two silver linings in the experience: More people have found her profiles, allowing her to share evidence-based information with an even wider audience, and she can now help other physicians protect themselves and reduce the risk of similar attacks, or at least know how to respond to them if they occur. Dr. Baldwin shared a wealth of tips and resources during her lecture to help pediatricians prepare ahead for the possibility that they will be targeted next, whether the issue is vaccines or another topic.
 

Online risks and benefits

A Pew survey of U.S. adults in September 2020 found that 41% have personally experienced online harassment, including a quarter of Americans who have experienced severe harassment. More than half of respondents said online harassment and bullying is a major problem – and that was a poll of the entire population, not even just physicians and scientists.

“Now, these numbers would be higher,” Dr. Baldwin said. “A lot has changed in the past 3 years, and the landscape is very different.”

The pandemic contributed to those changes to the landscape, including an increase in harassment of doctors and researchers. A June 2023 study revealed that two-thirds of 359 respondents in an online survey reported harassment on social media, a substantial number even after accounting for selection bias in the individuals who chose to respond to the survey. Although most of the attacks (88%) resulted from the respondent’s advocacy online, nearly half the attacks (45%) were gender based, 27% were based on race/ethnicity, and 13% were based on sexual orientation.

While hateful comments are likely the most common type of online harassment, other types can involve sharing or tagging your profile, creating fake profiles to misrepresent you, fake reviews of your practice, harassing phone calls and hate mail at your office, and doxxing, in which someone online widely shares your personal address, phone number, email, or other contact information.

For example, a recent report from the Kaiser Family Foundation revealed how many people weren’t sure whether certain health misinformation claims were true or false. Barely a third of people were sure that COVID-19 vaccines had not caused thousands of deaths in healthy people, and only 22% of people were sure that ivermectin is not an effective treatment for COVID.

Social media self-care

Dr. Baldwin acknowledged that experiencing a social media attack can be intense and even frightening, but it’s rare and outweighed by the “hundreds and hundreds and hundreds of positive comments all the time.” She also reminded attendees that being on social media doesn’t mean being there all the time.

“Over time, my use of social media has certainly changed. It ebbs and flows,” she said. “There are times when I have a lot of bandwidth and I’m posting a lot, and then I actually have had some struggles with my own mental health, with some anxiety and mild depression, so I took a break from social media for a while. When I came back, I posted about my mental health struggles, and you wouldn’t believe how many people were so appreciative of that.”
 

Accurate information from a trusted source

Ultimately, Dr. Baldwin sees her work online as an extension of her work educating patients.

“This is where our patients are. They are in your office for maybe 10-15 minutes maybe once a year, but they are on these platforms every single day for hours,” she said. “They need to see this information from medical professionals because there are random people out there that are telling them [misinformation].”

Elizabeth Murray, DO, MBA, an emergency medicine pediatrician at Golisano Children’s Hospital at the University of Rochester, agreed that there’s substantial value in doctors sharing accurate information online.

“Disinformation and misinformation is rampant, and at the end of the day, we know the facts,” Dr. Murray said. “We know what parents want to hear and what they want to learn about, so we need to share that information and get the facts out there.”

Dr. Murray found the session very helpful because there’s so much to learn across different social media platforms and it can feel overwhelming if you aren’t familiar with the tools.

“Social media is always going to be here. We need to learn to live with all of these platforms,” Dr. Murray said. “That’s a skill set. We need to learn the skills and teach our kids the skill set. You never really know what you might put out there that, in your mind is innocent or very science-based, that for whatever reason somebody might take issue with. You might as well be ready because we’re all about prevention in pediatrics.”

There were no funders for the presentation. Dr. Baldwin and Dr. Murray had no disclosures.

Which conditions are caused by infection? Though it may seem like an amateur concern in the era of advanced microscopy, some culprits evade conventional methods of detection. Large medical databases hold the power to unlock answers. 

A recent study from Sweden and Denmark meticulously traced the lives and medical histories of nearly one million men and women in those countries who had received blood transfusions over nearly five decades. Some of these patients later experienced brain bleeds. The inescapable question: Could a virus found in some donor blood have caused the hemorrhages?

Traditionally, brain bleeds have been thought to strike at random. But the new study, published in JAMA, points toward an infection that causes or, at the very least, is linked to the condition. The researchers used a large databank to make the discovery. 

“As health data becomes more available and easier to analyze, we’ll see all kinds of cases like this,” said Jingcheng Zhao, MD, of the clinical epidemiology division of Sweden’s Karolinska Institutet in Solna and lead author of the study.

Scientists say the field of medical research is on the cusp of a revolution as immense health databases guide discovery and improve clinical care. 

“If you can aggregate data, you have the statistical power to identify associations,” said David R. Crosslin, PhD, professor in the division of biomedical informatics and genomics at Tulane University in New Orleans. “It opens up the world for understanding diseases.”

With access to the large database, Dr. Zhao and his team found that some blood donors later experienced brain bleeds. And it turned out that the recipients of blood from those same donors carried the highest risk of experiencing a brain bleed later in life. Meanwhile, patients whose donors remained bleed-free had the lowest risk.
 

Not so fast in the United States

In Nordic countries, all hospitals, clinics, and pharmacies report data on diagnoses and health care visits to the government, tracking that began with paper and pen in the 1960s. But the United States health care system is too fragmented to replicate such efforts, with several brands of electronic medical records operating across different systems. Data sharing across institutions is minimal. 

Most comparable health data in the United States comes from reimbursement information collected by the Centers for Medicare & Medicaid Services on government-sponsored insurance programs.

“We would need all the health care systems in the country to operate within the same IT system or use the same data model,” said Euan Ashley, MD, PhD, professor of genomics at Stanford (Calif.) University. “It’s an exciting prospect. But I think [the United States] is one of the last countries where it’ll happen.”

States, meanwhile, collect health data on specific areas like sexually transmitted infection cases and rates. Other states have registries, like the Connecticut Tumor Registry, which was established in 1941 and is the oldest population-based cancer registry in the world.

But all of these efforts are ad hoc, and no equivalent exists for heart disease and other conditions.

Health data companies have recently entered the U.S. data industry mainly through partnerships with health systems and insurance companies, using deidentified information from patient charts.

The large databases have yielded important findings that randomized clinical trials simply cannot, according to Dr. Ashley.

For instance, a study found that a heavily-lauded immunotherapy treatment did not provide meaningful outcomes for patients aged 75 years or older, but it did for younger patients.

This sort of analysis might enable clinicians to administer treatments based on how effective they are for patients with particular demographics, according to Cary Gross, MD, professor at Yale University in New Haven, Conn.

“From a bedside standpoint, these large databases can identify who benefits from what,” Dr. Gross said. “Precision medicine is not just about genetic tailoring.” These large datasets also provide insight into genetic and environmental variables that contribute to disease. 

For instance, the UK Biobank has more than 500,000 participants paired with their medical records and scans of their body and brain. Researchers perform cognitive tests on participants and extract DNA from blood samples over their lifetime, allowing examination of interactions between risk factors. 

A similar but much smaller-scale effort underway in the United States, called the All of Us Research Program, has enrolled more than 650,000 people, less than one-third the size of the UK Biobank by relative populations. The goal of the program is to provide insights into prevention and treatment of chronic disease among a diverse set of at least one million participants. The database includes information on sexual orientation, which is a fairly new datapoint collected by researchers in an effort to study health outcomes and inequities among the LGBTQ+ community.

Dr. Crosslin and his colleagues are writing a grant proposal to use the All of Us database to identify genetic risks for preeclampsia. People with certain genetic profiles may be predisposed to the life-threatening condition, and researchers may discover that lifestyle changes could decrease risk, Dr. Crosslin said. 
 

Changes in the United States

The COVID-19 pandemic exposed the lack of centralized data in the United States because a majority of research on the virus has been conducted abroad in countries with national health care systems and these large databases. 

The U.S. gap spurred a group of researchers to create the National Institutes of Health–funded National COVID Cohort Collaborative (N3C), a project that gathers medical records from millions of patients across health systems and provides access to research teams investigating a wide spectrum of topics, such as optimal timing for ventilator use.

But until government or private health systems develop a way to share and regulate health data ethically and efficiently, significant limits will persist on what large-scale databases can do, Dr. Gross said. 

“At the federal level, we need to ensure this health information is made available for public health researchers so we don’t create these private fiefdoms of data,” Dr. Gross said. “Things have to be transparent. I think our country needs to take a step back and think about what we’re doing with our health data and how we can make sure it’s being managed ethically.”

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.

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.

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.

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).

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.

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.

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.
