WASHINGTON — The selective interleukin (IL)–23p29 monoclonal antibody mirikizumab demonstrated safety and efficacy in people with moderate to severe Crohn’s disease compared with placebo up to 52 weeks, according to results of the phase 3 randomized, double blind, treat-through VIVID-1 study. 

Bruce E. Sands, MD, AGAF, chief of gastroenterology at the Icahn School of Medicine at Mount Sinai in New York, reported the findings in a poster (Abstract Su1801) at the annual Digestive Disease Week^® (DDW).

The FDA approved mirikizumab (Omvoh, Eli Lilly) to treat moderate to severe ulcerative colitis in October 2023. 

Dr. Sands and a team of US and international collaborators studied 1065 adults with Crohn’s disease or fistulizing Crohn’s disease for 3 months or more, with a mean duration of more than 7 years. At baseline, participants had a Simple Endoscopic Score for Crohn’s Disease (SES-CD) of 7 or more and reported an inadequate response, lost response, or intolerance to other therapy.

A total of 579 people were randomly assigned to mirikizumab and another 199 to placebo. Another 287 patients received ustekinumab; though they were not included in this current analysis, the findings were presented separately at DDW 2024. 

Mean age of study participants was 30 years, and men comprised 57%-59% of the groups. Nearly half (49%) of each group previously failed biologic therapy. 

A primary composite endpoint was clinical response at 12 weeks according to patient reported outcome and endoscopic response at 52 weeks measured with the SES-CD. A second primary endpoint was clinical response at 12 weeks by patient reported outcome combined with clinical remission on Crohn’s Disease Activity Index (CDAI) at 52 weeks.

Researchers also tracked 12 major secondary endpoints for mirikizumab vs placebo, including clinical response, endoscopic response, and clinical remission at week 12 and week 52. 
 

Efficacy Findings

A higher percentage of participants in the mirikizumab group achieved 12-week secondary endpoints compared with placebo. In the treatment group, 32.5% reached endoscopic response vs 12.6% in the placebo group, a statistically significant difference (P < .000001). In addition, 17.6% achieved endoscopic remission in the treatment group vs 7.0% in the placebo group at 12 weeks (P < .000213).

The “treat-through” results at 52 weeks revealed that a higher proportion of the group taking mirikizumab met the co-primary endpoints compared with placebo. A total of 48.4% in the mirikizumab group vs 9.0% in the placebo group achieved endoscopic response (P < .000001). Similarly, a higher proportion met clinical remission on the CDAI, 54.1% in the treatment group vs 19.6% in the placebo group (P < .000001).

Overall, 38% of mirikizumab-treated patients vs 9% of the placebo group reached a composite endpoint of patient reported clinical response at week 12 and endoscopic response by SES-CD at week 52 (P < .000001).

Dr. Sands and colleagues also combined clinical response reported by patients at 12 weeks with CDAI findings for clinical remission at week 52. A total of 45.4% in the treatment group met the combined endpoint compared with 19.6% of the placebo group (P < .000001). 

In an additional analysis, the researchers looked at this composite endpoint in patients in both groups who had failed or not failed a prior biologic for a total of 43.4% vs 12.4%, and 47.3% vs 26.5%, respectively.

“Mirikizumab demonstrated statistically significant and clinically meaningful improvements” in the study co-primary endpoints and secondary endpoints compared with placebo, the researchers concluded. 
 

Safety Findings

Safety outcomes during the 52-week study were “consistent with the known safety profile” of mirikizumab, the researchers noted. 

Treatment-emergent adverse events occurred in 78.6% of mirikizumab participants vs 73.0% of the placebo group. The most common were COVID-19, anemia, and arthralgia. Serious adverse events were reported in 10.3% of the mirikizumab group vs 17.1% of the placebo group. There were seven opportunistic infections in the treatment group, including herpes zoster and Candida, compared with none in the placebo group. 

One person in the placebo cohort died of a pulmonary embolism; there were no deaths in the mirikizumab group. 

People randomly assigned to placebo without a response at 12 weeks were switched over to mirikizumab. However, the findings from this group between 12 and 52 weeks were excluded from the 1-year data presented at DDW 2024, including one death from worsening Crohn’s disease during that time.

Mirikizumab looked particularly robust in this study, and it may turn out to be a critically important option for our patients, said Jordan Axelrad, MD, MPH, co-director of the Inflammatory Bowel Disease Center at NYU Langone Health in New York City. Dr. Axelrad was not involved in this study. 

Of importance, effect sizes were similar for “bio-naive and previously biologic-exposed patients,” he added. 

These data “really underscore that therapies targeting IL-23 may be clinically useful for Crohn’s disease patients with prior biologic failure, representing a significant departure from our previous experience with other biologic classes,” Dr. Axelrad said.

The study was funded by Eli Lilly and Company. Dr. Sands is a consultant and receives grant funding from Lilly. Dr. Axelrad had no relevant disclosures.

Just over 2 months into 2024, measles cases in the United States aren’t looking great. 

The recent rise in cases across the U.S. is linked to unvaccinated travelers, lower than ideal vaccination rates, and misinformation, experts said. 

The Centers for Disease Control and Prevention has identified 45 cases of measles in 17 jurisdictions across the U.S. As of March 7, the federal health agency reported measles cases in Arizona, California, Florida, Georgia, Illinois, Indiana, Louisiana, Maryland, Michigan, Minnesota, Missouri, New Jersey, New York City, Ohio, Pennsylvania, Virginia, and Washington.

As for the 45 cases, “that’s almost as many as we had for the entire calendar year of 2023,” said Sarah Lim, MD, a medical specialist at the Minnesota Department of Health. “So we’re really not off to a great start.” (For context, there were 58 officially reported measles cases last year.) 

Chicago is having a measles outbreak — with eight cases reported so far. All but one case has been linked to a migrant child at a city shelter. Given the potential for rapid spread — measles is relatively rare here but potentially very serious — the CDC sent a team of experts to investigate and to help keep this outbreak from growing further.


 

Sometimes Deadly

About 30% of children have measles symptoms and about 25% end up hospitalized. Complications include diarrhea, a whole-body rash, ear infections that can lead to permanent deafness, and pneumonia. Pneumonia with measles can be so serious that 1 in 20 affected children die. Measles can also cause inflammation of the brain called encephalitis in about 1 in 1,000 children, sometimes causing epilepsy or permanent brain damage.

As with long COVID, some effects can last beyond the early infection. For example, measles “can wipe out immune memory that protects you against other bacterial and viral pathogens,” Dr. Lim said at a media briefing sponsored by the Infectious Diseases Society of America. This vulnerability to other infections can last up to 3 years after the early infection, she noted. 

Overall, measles kills between 1 and 3 people infected per thousand, mostly children.
 

Vaccine Misinformation Playing a Role

Vaccine misinformation is partly behind the uptick, and while many cases are mild, “this can be a devastating disease,” said Joshua Barocas, MD, associate professor of medicine in the divisions of General Internal Medicine and Infectious Diseases at the University of Colorado School of Medicine.

“I’m a parent myself. Parents are flooded with tons of information, some of that time being misinformation,” he said at the media briefing. “If you are a parent who’s been on the fence [about vaccination], now is the time, given the outbreak potential and the outbreaks that we’re seeing.” 

Vaccine misinformation “is about as old as vaccines themselves,” Dr. Lim said. Concerns about the MMR vaccine, which includes measles protection, are not new.

“It does seem to change periodically — new things bubble up, new ideas bubble up, and the problem is that it is like the old saying that ‘a lie can get halfway around the world before the truth can get its boots on.’ ” Social media helps to amplify vaccine misinformation, she said. 

“You don’t want to scare people unnecessarily — but reminding people what these childhood diseases really look like and what they do is incredibly important,” Dr. Lim said. “It’s so much easier to see stories about potential side effects of vaccines than it is to see stories about parents whose children were in intensive care for 2 weeks with pneumonia because of a severe case of measles.”

Dr. Barocas said misinformation is sometimes deliberate, sometimes not. Regardless, “our job as infectious disease physicians and public health professionals is not necessarily to put the counternarrative out there, but to continue to advocate for what we know works based on the best science and the best evidence.”

“And there is no reason to believe that vaccines are anything but helpful when it comes to preventing measles,” he noted. 
 

Lifelong Protection in Most Cases

The MMR vaccine, typically given as two doses in childhood, offers 93% and then 97% protection against the highly contagious virus. During the 2022-to-2023 school year, the measles vaccination rate among kindergarten children nationwide was 92%. That sounds like a high rate, Dr. Lim said, “but because measles is so contagious, vaccination rates need to be 95% or higher to contain transmission.”

One person with measles can infect anywhere from 12 to 18 other people, she said. When an infected person coughs or sneezes, tiny droplets spread through the air. “And if someone is unvaccinated and exposed, 9 times out of 10, that person will go on to develop the disease.” She said given the high transmission rate, measles often spreads within families to infect multiple children. 

If you know you’re not vaccinated but exposed, the advice is to get the measles shot as quickly as possible. “There is a recommendation to receive the MMR vaccine within 72 hours as post-exposure prophylaxis,” Dr. Lim said. “That’s a tight time window, but if you can do that, it reduces the risk of developing measles significantly.”

If you’re unsure or do not remember getting vaccinated against measles as a young child, your health care provider may be able to search state registries for an answer. If that doesn’t work, getting revaccinated with the MMR vaccine as an adult is an option. “There is no shame in getting caught up now,” Dr. Barocas said.

Dr. Lim agreed. “There is really no downside to getting additional doses.”

ORLANDO, FLORIDA — New potential treatment strategies for people with rosacea include botulinum toxin, the antidepressant paroxetine, and a low-molecular-weight analog of heparan sulfate, according to evidence published in the last year. At the same time, there is new recognition that systemic inflammation can occur with rosacea, and targeting treatment to the phenotype continues to gain steam as a way to help people with this difficult-to-manage condition.

“Anyone here think they’ve got rosacea under control? No, I wish — not yet,” Diane Dr. Thiboutot, MD, said at the annual ODAC Dermatology, Aesthetic & Surgical Conference.
 

Botulinum Toxin Benefits

With that in mind, Dr. Thiboutot highlighted emerging therapies for treating rosacea. “Last year, there were a couple of reports … looking at the use of botulinum toxin injections for patients with rosacea,” said Dr. Thiboutot, professor of dermatology and vice chair for research in the Department of Dermatology at Penn State College of Medicine, Hershey, Pennsylvania.

One report describes the case of a woman with rosacea who had severe recurrent episodes of erythema and flushing. She also experienced occasional papules and pustules and had been recalcitrant to multiple treatments for rosacea, according to the report published in the Journal of Drugs in Dermatology in June 2023. The patient was treated with a total of 150-180 units of botulinum toxin administered as 3-6 units spaced 1 cm apart every 2-4 months. She was “eventually maintained every 6 months with excellent improvement,” Dr. Thiboutot said.

In another case, a man with refractory vascular and papulopustular rosacea was treated with half of a unit of botulinum toxin spaced every 0.5 cm. Images taken at baseline, 1 month, and 3 months after treatment demonstrated improvements, as reported in June 2023.

Regarding botulinum toxin for rosacea, Dr. Thiboutot said, “it’s a very interesting thing to think about.”

Susan Weinkle, MD, ODAC conference cochair, session moderator, and collaborative associate professor of dermatology at the University of South Florida, Tampa, Florida, agreed. “I do think it holds some interesting potential,” she said. “How good are your hands? Because administering 0.5-unit injections evenly is a little bit challenging.”

However, one approach that might help is “if we could be a little more innovative like they are in Europe.” Physicians in Europe can use a metered syringe, one where they dial in the exact amount per injection, which allows them to be consistent, she added.

With rosacea erythema, Dr. Thiboutot noted, a spotted effect can result if injections are not administered uniformly.
 

Potential Role for Paroxetine

The antidepressant paroxetine, a potent selective serotonin reuptake inhibitor, could be an effective treatment for refractory erythema of rosacea, Dr. Thiboutot said. It is approved for treating depression, obsessive-compulsive disorder, and social phobia. The agent has also shown effectiveness in alleviating hot flashes associated with vascular dysregulation in menopause.

Uptake in serotonin and changes in receptors are closely related to vascular dilation and constriction, Dr. Thiboutot added, so paroxetine “may be beneficial in treating vascular dysfunction” including in people with rosacea. Evidence to support this potential approach comes from the primary results of a randomized controlled trial published in June 2023. Based on the results, the researchers concluded that paroxetine “appears to be an efficacious and well-tolerated treatment for refractory erythema in rosacea.”

In the trial, almost 43% of people treated with paroxetine met the primary endpoint for improving recalcitrant erythema at week 12 compared with almost 21% who took a placebo, a statistically significant difference.
 

Heparan Sulfate Analog in a Cream

Evidence suggests that a low-molecular-weight heparan sulfate analog is another agent that holds potential for treating rosacea. For example, a 2023 randomized controlled trial evaluated the immune response in rosacea, focusing on a specific cathelicidin peptide called LL-37 that activates an inflammasome in rosacea. Low-molecular-weight heparan sulfate holds the potential to inhibit LL-37 activity, as LL-37 is inhibited by binding to heparan sulfate, a cell surface glycosaminoglycan.

The study of 16 people assessed the ability of the analog to modulate this response; they were also treated with the pulsed dye laser. Participants who applied a dermal repair cream that contained this ingredient experienced a one-grade reduction in erythema at weeks 4 and 8 compared with a control group applying a moisturizer.

A Growing Case for Systemic Inflammation

In the meantime, treating rosacea with more traditional therapies remains challenging.

But there’s hope. Success has been reported in the few years since an expert panel recommended treating based on phenotype — a treat-what-you-see approach, Dr. Thiboutot said.

“We don’t have a single treatment that is one-size-fits-all. We have to individualize our treatment [based] more on what we are seeing and what the patient is experiencing.”

Eventually, therapies to treat systemic inflammation could provide benefits as well. As with hidradenitis suppurativa and psoriasis, “there’s evidence of systemic inflammation in some of our rosacea patients,” Dr. Thiboutot said.

For example, researchers compared blood taken from people with and without rosacea and found increased levels of some inflammatory markers among participants with the condition.

The retrospective study published in June 2023 in Scientific Reports included 100 patients with rosacea and 58 controls. The investigators found significantly higher elevations in the SII index, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) levels in the patients with rosacea.

“There was no significant link between the severity of rosacea and the ESR, CRP, or SII index values, Dr. Thiboutot added. “This study suggests inflammation beyond the skin in rosacea patients.”

For more guidance on treating rosacea through standard management options, including how to tailor therapy to each individual, she recommended the 2019 Update by the National Rosacea Society Expert Committee. “It’s a nice quick way to see, based on expert opinion, the most effective treatments and what the evidence base is,” said Dr. Thiboutot, lead author of the paper, published in the Journal of the American Academy of Dermatology in February 2020.

Dr. Thiboutot reported no relevant financial relationships.

ORLANDO, FLORIDA — For some people, acne carries a one-two punch. First, they experience acne that is significant enough to decrease their quality of life, followed by scarring that can last a lifetime. For those patients, dermatologists have several options: Subcision to lift the depression of the scar, laser treatment to lower the height of scar tissue, and injections to fill scars.

“In my practice, I find that these [acne scars] are probably the hardest things to treat. But along the way, I created a protocol that I would love to share with you today,” Robyn Siperstein, MD, said at the annual ODAC Dermatology, Aesthetic & Surgical Conference.

Dr. Siperstein starts by identifying the type of acne scar — rolling scars, boxcar scars, or ice pick scars. Rolling scars tend to be shallower with no sharp edges; boxcar scars are deeper, more defined round or oval depressions; and ice pick scars, as the name suggests, look like someone stuck tiny ice picks into the skin, leaving a sunken or pitted appearance.

“It’s really important to categorize so that we know which ones are going to be effectively treated with different modalities and which ones aren’t, so that we can give our patients realistic expectations,” said Dr. Siperstein, a cosmetic dermatologist in private practice in Boca Raton, Florida, and a clinical affiliate associate professor of dermatology at Florida Atlantic University, Boca Raton.

“There’s not going to be one treatment that’s right for everything,” she said. Different approaches may be required even for the same patient because some people present with all three types of acne scars, she added.

Combining Treatments

When it comes to injecting dermal fillers into acne scars to lift the depressed areas, the US Food and Drug Administration approved a filler with polymethyl methacrylate filler and bovine collagen (Bellafill) for this indication (moderate to severe, atrophic, distensible facial acne scars on the cheek in patients over age 21) in 2015. “And off-label, I use hyaluronic acid in my practice,” Dr. Siperstein said. Each filler “probably works a little bit better or differently on different types of scars.”

For rolling scars, she recommends hyaluronic acid (HA) dermal filler for everyone. “Of course, this is my opinion.” She was also a lead investigator in a randomized, placebo-controlled split-face study comparing HA filler with saline for correcting atrophic facial scars in 15 patients. The HA filler emerged superior, although there were some improvements with saline.

In her clinical experience, patients are happy with the results and ask, “Why didn’t the last four doctors do this?”

Boxcar scars are more challenging to fill with HA. In some cases, Dr. Siperstein is able to raise the depressed portion of the scar, but some of the vertical edges remain. In this scenario, she might combine treatments. Laser resurfacing, for example, might help convert boxcar scars into rolling scars, which then can be filled more successfully.

“Ice pick scars are tough,” Dr. Siperstein said. A punch removal technique can work in some cases, or she might try the “cross technique.” This involves placing acetic acid inside the scar using a Q-tip. “You have to be really careful,” she added, “because if you get it around the edges, it’s actually going to make the scar bigger.”
 

Choosing the Right Candidates

Selecting the right candidate for HA treatment of acne scars is essential. Dr. Siperstein shared the example of a lifeguard who had prominent acne scarring down the center of his chest. “He was embarrassed to go to the beach and take off his shirt. He said he felt like he had bullet holes in his chest.”

One month following treatment, “he had a really nice improvement, and now he feels really comfortable,” she said.

Some dermatologists might be reluctant to consider HA fillers for acne scarring because there is a misconception that HA is short-acting, lasting 6 months to 1 year before the effect wears off. That impression can persist from company-sponsored studies that limit follow-up to 6 months or 1 year “to get their drug to market,” she noted.

Also adding to this impression is that HA fillers in wrinkles may not last as long. Dr. Siperstein explained that wrinkles on the face are dynamic and constantly moving. In contrast, acne scars experience less movement, which helps the HA last longer. There is MRI evidence that shows HA fillers last over 2 years in the face, she added.

One tip to predict how well an acne scar might respond to filler injections is to squeeze it and look for the “dimple sign.” If the floor of the scar lifts up when squeezed, “we know that they’ll be a good candidate for hyaluronic acid filler.” Another tip is to inject HA in a retrograde technique high up in the skin. Inject tiny amounts — microdroplets — of the HA filler high on the dermis, she advised.

Deeper injections run the risk of raising the entire scar instead of filling it, she added.

Like many dermatologic procedures, before and after photos are essential to demonstrate improvements, Dr. Siperstein pointed out. Patients are often skeptical. “This happens a lot with acne scar patients. They’ve been to a million places that have promised results, they have not gotten them, and they are frustrated.”

Acne scars can result from picking, inflammation, or treatment. “This is what we see all day in clinic,” Dr. Siperstein said. “Somebody who had to undergo Accutane treatment but unfortunately is left with holes. This is a huge psychological burden on our patients,” she said, describing a younger patient who had scarring, which “led to depression — it was ruining his life.”

“His mom was willing to do whatever it took. And I said, You know what, I think filler will be enough,” Dr. Siperstein said. She counseled them that treatment would not make the scars disappear completely. But patients used to 10% improvements are very happy when their acne scars look 80% or 90% better, she added.

Dr. Siperstein received grant or research support and is a member of the speakers bureau for Allergan and Galderma. She is also a consultant/advisory board member for Allergan.

One month following treatment, “he had a really nice improvement, and now he feels really comfortable,” she said.

Some dermatologists might be reluctant to consider HA fillers for acne scarring because there is a misconception that HA is short-acting, lasting 6 months to 1 year before the effect wears off. That impression can persist from company-sponsored studies that limit follow-up to 6 months or 1 year “to get their drug to market,” she noted.

Also adding to this impression is that HA fillers in wrinkles may not last as long. Dr. Siperstein explained that wrinkles on the face are dynamic and constantly moving. In contrast, acne scars experience less movement, which helps the HA last longer. There is MRI evidence that shows HA fillers last over 2 years in the face, she added.

One tip to predict how well an acne scar might respond to filler injections is to squeeze it and look for the “dimple sign.” If the floor of the scar lifts up when squeezed, “we know that they’ll be a good candidate for hyaluronic acid filler.” Another tip is to inject HA in a retrograde technique high up in the skin. Inject tiny amounts — microdroplets — of the HA filler high on the dermis, she advised.

Deeper injections run the risk of raising the entire scar instead of filling it, she added.

Like many dermatologic procedures, before and after photos are essential to demonstrate improvements, Dr. Siperstein pointed out. Patients are often skeptical. “This happens a lot with acne scar patients. They’ve been to a million places that have promised results, they have not gotten them, and they are frustrated.”

Acne scars can result from picking, inflammation, or treatment. “This is what we see all day in clinic,” Dr. Siperstein said. “Somebody who had to undergo Accutane treatment but unfortunately is left with holes. This is a huge psychological burden on our patients,” she said, describing a younger patient who had scarring, which “led to depression — it was ruining his life.”

“His mom was willing to do whatever it took. And I said, You know what, I think filler will be enough,” Dr. Siperstein said. She counseled them that treatment would not make the scars disappear completely. But patients used to 10% improvements are very happy when their acne scars look 80% or 90% better, she added.

Dr. Siperstein received grant or research support and is a member of the speakers bureau for Allergan and Galderma. She is also a consultant/advisory board member for Allergan.

ORLANDO — “Itch may not be as sexy as Mohs surgery or aesthetic procedures,” but treating it is important and meaningful to patients, particularly those who’ve found little relief previously, Shawn G. Kwatra, MD, said at the annual ODAC Dermatology, Aesthetic & Surgery Conference.

Chronic itch is common, with presentations that range from annoying to debilitating. There are many over-the-counter and prescription treatments patients can and likely have tried by the time they seek a dermatologist for help.

In doctors’ defense, it can be highly challenging to know which approach is optimal for each individual with pruritus, added Dr. Kwatra, associate professor of dermatology at Johns Hopkins University, Baltimore, Maryland.

Cooling agents, topical capsaicin, topical anesthetics like pramoxine 1%, various forms of lidocaine, strontium, opioid modulators like naltrexone, oral Janus kinase inhibitor (JAK) inhibitors, and medical marijuana are among some of the “outside the box” tools in Dr. Kwatra’s itch toolbox.
 

Often a Medical Puzzle

Frequently, patients come to the dermatologist complaining of itch, “but you don’t see much on their skin.” After a trial of antihistamines, and some topical steroids, the doctor might put up their hands and think: I tried, but I don’t know what else to do. “This actually happens a lot,” said Dr. Kwatra, who is also director of the Johns Hopkins Itch Center.

This means itch can frustrate providers as well. But for patients, the impact on their quality of life can be on the same level as recovering from a stroke or living with heart failure, Dr. Kwatra said. Finding relief for their itch is where “we can make a big difference for patients.”
 

Consider Cooling Agents

Many of these therapies are inexpensive and widely available. Cooling agents like menthol, camphor, or calamine can reduce activity of the transient receptor potential (TRP) channels in the skin associated with itch. This ion channel also senses temperature, pressure, and other sensations.

Another option is topical capsaicin, which works through the same ion channels. It binds to the TRPV1 receptors in sensory nerve fibers and causes desensitization. Initially, four to six applications a day are required to reduce itch. After that, patients can apply the medication less frequently. “You have to tell folks we know it’s going to work, but it’s going to burn a lot initially,” Dr. Kwatra said. “In real world practice, I’m not using it often.”

A 1.8% capsaicin patch, approved for treating postherpetic neuralgia, can be used to treat pruritus as well. “You put the patch on for one hour and you can have a true clinical response,” he noted.

Another option for itch relief, the topical anesthetic pramoxine 1%, “is probably underutilized for our patients,” Dr. Kwatra said. Pramoxine 1% works fast — as quickly as 2 minutes — and lasts up to 8 hours and is well-tolerated with low toxicity, he added. The agent is applied three to four times a day and relieves itch by reducing the transmembrane permeability of sodium ions on the skin. “This is something widely available and cheap.”

Lidocaine, another topical anesthetic, is available compounded, over the counter, and as a spray or patch. “I would be careful before you use high doses, like 10%” because of tolerability issues, Dr. Kwatra cautioned. He generally starts with lower concentrations.

Topical strontium is really interesting as a strategy, Dr. Kwatra said. Strontium is a soft, white metal that competes with calcium for receptor binding. There are over-the-counter formulations available as a scalp solution or lotion, which, he said, “are ways to go with more episodic itching.”

Topical oatmeal can also relieve itch in some patients. “There is actually some good scientific evidence for topical oatmeal preparations,” he said.
 

Steroid-Sparing Novel Topicals

Topical ruxolitinib (a JAK inhibitor approved for atopic dermatitis and vitiligo); topical roflumilast (a phosphodiesterase-4 inhibitor) and topical tapinarof (an aryl hydrocarbon receptor agonist), both approved for treating psoriasis; and the atopic dermatitis drug crisaborole fall into this category of topicals with potential for treating itch, he said, noting that use for treating itch is off label.

Off-label use of biologic agents are also possible treatment options for itch, dupilumab and tralokinumab, both US Food and Drug Administration (FDA)–approved for treating atopic dermatitis. Emerging agents that may prove useful for treating itch include lebrikizumab, nemolizumab, amlitelimab, and rocatinlimab, he said.

In terms of oral therapies, the FDA has approved two oral JAK inhibitors for atopic dermatitis, abrocitinib and upadacitinib, which could prove useful for itch as an off-label indication, according to Dr. Kwatra.
 

Naltrexone Off Label

An emerging therapeutic concept for treating itch is using an opioid antagonist like naltrexone. Morphine causes more itch, so the theory is a reversal agent might help reduce it. The challenge is that naltrexone only comes as a 50 mg tablet, “and I find the high dose makes people nauseous and vomit,” he added.

Don’t Forget Devices

He referred to a “great paper” that he said has been “totally overlooked,” published in 2001, which evaluated a device that stimulates C fibers in the skin to reduce itch. In the study, 19 patients used the device to treat local areas 20 minutes daily for 5 weeks. Punch biopsies of the affected areas were taken at baseline and after treatment. Mean itch ratings decreased from 78% to 42%, and the number of immunoreactive nerve fibers in the epidermis decreased by 40% at the end of treatment.

“Electrical neurostimulation is better for localized pruritus. There is limited case series evidence, but it’s something to think about,” Dr. Kwatra said.

He and his colleagues also have a case study in press that explored the use of injected botulinum toxin to relieve recalcitrant, chronic itch in a 65-year-old man “who failed everything.”

Dr. Kwatra is a consultant or advisory board member for AbbVie, Amgen, Arcutis Biotherapeutics, ASLAN Pharmaceuticals, Cara Therapeutics, Castle Biosciences, Celldex Therapeutics, Galderma, Incyte Corporation, Johnson & Johnson, LEO Pharma, Novartis, Pfizer, Regeneron, and Sanofi.

ORLANDO, FLORIDA — Advances in treating medical conditions rarely emerge in a straight line. Oftentimes, progress comes in fits and starts, and therapies to treat cutaneous lupus erythematosus (CLE) and dermatomyositis are no exception.

Beyond approved treatments that deserve more attention, like belimumab, approved by the Food and Drug Administration (FDA) for systemic lupus erythematosus (SLE) in 2011, and Octagam 10%, an intravenous immune globulin (IVIG) preparation approved for dermatomyositis in 2021, anticipation is growing for emerging therapies and their potential to provide relief to patients, Anthony Fernandez, MD, PhD, said at the ODAC Dermatology, Aesthetic & Surgical Conference. The tyrosine kinase 2 (TYK2) inhibitor deucravacitinib, Janus kinase (JAK) inhibitors brepocitinib and baricitinib, and the monoclonal antibody anifrolumab, he noted, are prime examples.

“There have been significant advances in the development of treatments for lupus erythematosus and dermatomyositis. In my opinion, this is the start of what will be the most exciting decade in the history of these two diseases,” said Dr. Fernandez, director of medical dermatology at the Cleveland Clinic.
 

Emerging Treatments for Cutaneous Lupus

Although SLE can involve many organ systems, the skin is one of the most affected. There are specific cutaneous lesions categorized as either acute cutaneous lupus, subacute cutaneous lupus, or chronic cutaneous lupus.

The oral TYK2 inhibitor deucravacitinib, for example, should be able to dampen interleukin responses in people with CLE, Dr. Fernandez said. Deucravacitinib was approved by the FDA to treat psoriasis in September 2022.

Cleveland Clinic Foundation

A phase 2 study published in 2023 focused on this agent for relief of systemic lupus. Improvements in cutaneous disease were a secondary endpoint. The trial demonstrated that the patients treated with deucravacitinib achieved a 56%-70% CLASI-50 response, depending on dosing, compared with a 17% response among those on placebo at week 48.

Based on the trial results, recruitment has begun for a phase 2 trial to evaluate deucravacitinib, compared with placebo, in patients with discoid and/or subacute cutaneous lupus. “This may be another medicine we have available to give to any of our patients with cutaneous lupus,” Dr. Fernandez said.
 

Anifrolumab Appears Promising

The FDA approval of anifrolumab, a type I interferon (IFN) receptor antagonist, for treating moderate to severe SLE in July 2021, for example, is good news for dermatologists and their patients, added Dr. Fernandez. “Almost immediately after approval, case studies showed marked improvement in patients with refractory cutaneous lupus.” While the therapy was approved for treating systemic lupus, it allows for off-label treatment of the cutaneous predominant form of the disease, he said.

Furthermore, the manufacturer of anifrolumab, AstraZeneca, is launching the LAVENDER clinical trial to assess the monoclonal antibody specifically for treating CLE. “This is a big deal because we may be able to prescribe anifrolumab for our cutaneous lupus patients who don’t have systemic lupus,” Dr. Fernandez said.

Phase 3 data supported use the of anifrolumab in systemic lupus, including the TULIP-2 trial, which demonstrated its superiority to placebo for reducing severity of systemic disease and lowering corticosteroid use. A study published in March 2023 of 11 patients showed that they had a “very fast response” to the agent, Dr. Fernandez said, with a 50% or greater improvement in the Cutaneous Lupus Erythematosus Disease Area and Severity Index activity score reached by all participants at week 16. Improvements of 50% or more in this scoring system are considered clinically meaningful, he added.
 

Upcoming Dermatomyositis Treatments

Why highlight emerging therapies for CLE and dermatomyositis in the same ODAC presentation? Although distinct conditions, these autoimmune conditions are both mediated by type 1 IFN inflammation.

Dermatomyositis is a relatively rare immune-mediated disease that most commonly affects the skin and muscle. Doctors score disease presentation, activity, and clinical improvements on a scale similar to CLASI for cutaneous lupus, the CDASI or Cutaneous Dermatomyositis Disease Area and Severity Index. Among people with CDASI activity scores of at least 14, which is the threshold for moderate to severe disease, a 20% improvement is clinically meaningful, Dr. Fernandez said. In addition, a 40% or greater improvement correlates with significant improvements in quality of life.

There is now more evidence for the use of IVIG to treat dermatomyositis. “Among those of us who treat dermatomyositis on a regular basis, we believe IVIG is the most potent treatment. We’ve known that for a long time,” Dr. Fernandez said.

Despite this tenet, for years, there was only one placebo-controlled trial, published in 1993, that evaluated IVIG treatment for dermatomyositis, and it included only 15 participants. That was until October 2022, he said, when the New England Journal of Medicine published a study comparing a specific brand of IVIG (Octagam) with placebo in 95 people with dermatomyositis.

In the study, 79% of participants treated with IVIG had a total improvement score of at least 20 (minimal improvement), the primary endpoint, at 16 weeks, compared with 44% of those receiving a placebo. Those treated with IVIG also had significant improvements in the CDASI score, a secondary endpoint, compared with those on placebo, he said.

Based on results of this trial, the FDA approved Octagam 10% for dermatomyositis in adults. Dr. Fernandez noted the approval is restricted to the brand of IVIG in the trial, not all IVIG products. However, “the FDA approval is most important to us because it gives us ammunition to fight for insurers to approve IVIG when we feel our patients with dermatomyositis need it,” regardless of the brand.
 

The Potential of JAK1 Inhibitors

An open-label study of the JAK inhibitor tofacitinib, published in December 2020, showed that mean changes in CDASI activity scores at 12 weeks were statistically significant compared with baseline in 10 people with dermatomyositis. “The importance of this study is that it is proof of concept that JAK inhibition can be effective for treating dermatomyositis, especially with active skin disease,” Dr. Fernandez said.

In addition, two large phase 3 trials are evaluating JAK inhibitor safety and efficacy for treating dermatomyositis. One is the VALOR trial, currently recruiting people with recalcitrant dermatomyositis to evaluate treatment with brepocitinib. Researchers in France are looking at another JAK inhibitor, baricitinib, for treating relapsing or treatment-naive dermatomyositis. Recruitment for the BIRD clinical trial is ongoing.

Monoclonal Antibody Showing Promise

“When it comes to looking specifically at dermatomyositis cutaneous disease, it’s been found that the levels of IFN beta correlate best with not only lesional skin type 1 IFN inflammatory signatures but also overall clinical disease activity,” Dr. Fernandez said. This correlation is stronger than for any other IFN-1-type cytokine active in the disorder.

“Perhaps blocking IFN beta might be best way to get control of dermatomyositis activity,” he added.

With that in mind, a phase 2 trial of dazukibart presented at the American Academy of Dermatology 2023 annual meeting highlighted the promise of this agent that targets type 1 IFN beta.

The primary endpoint was improvement in CDASI at 12 weeks. “This medication has remarkable efficacy,” Dr. Fernandez said. “We were one of the sites for this trial. Despite being blinded, there was no question about who was receiving drug and who was receiving placebo.”

“A minimal clinical improvement in disease activity was seen in more than 90%, so almost every patient who received this medication had meaningful improvement,” he added.

Based on the results, the manufacturer, Pfizer, is recruiting participants for a phase 3 trial to further assess dazukibart in dermatomyositis and polymyositis. Dr. Fernandez said, “This is a story you should pay attention to if you treat any dermatomyositis patients at all.”

Regarding these emerging therapies for CLE and dermatomyositis, “This looks very much like the early days of psoriasis, in the early 2000s, when there was a lot of activity developing treatments,” Dr. Fernandez said. “I will predict that within 10 years, we will have multiple novel agents available that will probably work better than anything we have today.”

Dr. Fernandez reported receiving grant and/or research support from Alexion, Incyte, Mallinckrodt Pharmaceuticals, Novartis, Pfizer, and Priovant Therapeutics; acting as a consultant or advisory board member for AbbVie, Biogen, Mallinckrodt Pharmaceuticals; and being a member of the speaker bureau or receiving honoraria for non-CME from AbbVie, Kyowa Kirin, and Mallinckrodt Pharmaceuticals.

A study published in March 2023 of 11 patients showed that they had a “very fast response” to the agent, Dr. Fernandez said, with a 50% or greater improvement in the Cutaneous Lupus Erythematosus Disease Area and Severity Index activity score reached by all participants at week 16. Improvements of 50% or more in this scoring system are considered clinically meaningful, he added.
 

Upcoming Dermatomyositis Treatments

Why highlight emerging therapies for CLE and dermatomyositis in the same ODAC presentation? Although distinct conditions, these autoimmune conditions are both mediated by type 1 IFN inflammation.

Dermatomyositis is a relatively rare immune-mediated disease that most commonly affects the skin and muscle. Doctors score disease presentation, activity, and clinical improvements on a scale similar to CLASI for cutaneous lupus, the CDASI or Cutaneous Dermatomyositis Disease Area and Severity Index. Among people with CDASI activity scores of at least 14, which is the threshold for moderate to severe disease, a 20% improvement is clinically meaningful, Dr. Fernandez said. In addition, a 40% or greater improvement correlates with significant improvements in quality of life.

There is now more evidence for the use of IVIG to treat dermatomyositis. “Among those of us who treat dermatomyositis on a regular basis, we believe IVIG is the most potent treatment. We’ve known that for a long time,” Dr. Fernandez said.

Despite this tenet, for years, there was only one placebo-controlled trial, published in 1993, that evaluated IVIG treatment for dermatomyositis, and it included only 15 participants. That was until October 2022, he said, when the New England Journal of Medicine published a study comparing a specific brand of IVIG (Octagam) with placebo in 95 people with dermatomyositis.

In the study, 79% of participants treated with IVIG had a total improvement score of at least 20 (minimal improvement), the primary endpoint, at 16 weeks, compared with 44% of those receiving a placebo. Those treated with IVIG also had significant improvements in the CDASI score, a secondary endpoint, compared with those on placebo, he said.

Based on results of this trial, the FDA approved Octagam 10% for dermatomyositis in adults. Dr. Fernandez noted the approval is restricted to the brand of IVIG in the trial, not all IVIG products. However, “the FDA approval is most important to us because it gives us ammunition to fight for insurers to approve IVIG when we feel our patients with dermatomyositis need it,” regardless of the brand.
 

The Potential of JAK1 Inhibitors

An open-label study of the JAK inhibitor tofacitinib, published in December 2020, showed that mean changes in CDASI activity scores at 12 weeks were statistically significant compared with baseline in 10 people with dermatomyositis. “The importance of this study is that it is proof of concept that JAK inhibition can be effective for treating dermatomyositis, especially with active skin disease,” Dr. Fernandez said.

In addition, two large phase 3 trials are evaluating JAK inhibitor safety and efficacy for treating dermatomyositis. One is the VALOR trial, currently recruiting people with recalcitrant dermatomyositis to evaluate treatment with brepocitinib. Researchers in France are looking at another JAK inhibitor, baricitinib, for treating relapsing or treatment-naive dermatomyositis. Recruitment for the BIRD clinical trial is ongoing.

Monoclonal Antibody Showing Promise

“When it comes to looking specifically at dermatomyositis cutaneous disease, it’s been found that the levels of IFN beta correlate best with not only lesional skin type 1 IFN inflammatory signatures but also overall clinical disease activity,” Dr. Fernandez said. This correlation is stronger than for any other IFN-1-type cytokine active in the disorder.

“Perhaps blocking IFN beta might be best way to get control of dermatomyositis activity,” he added.

With that in mind, a phase 2 trial of dazukibart presented at the American Academy of Dermatology 2023 annual meeting highlighted the promise of this agent that targets type 1 IFN beta.

The primary endpoint was improvement in CDASI at 12 weeks. “This medication has remarkable efficacy,” Dr. Fernandez said. “We were one of the sites for this trial. Despite being blinded, there was no question about who was receiving drug and who was receiving placebo.”

“A minimal clinical improvement in disease activity was seen in more than 90%, so almost every patient who received this medication had meaningful improvement,” he added.

Based on the results, the manufacturer, Pfizer, is recruiting participants for a phase 3 trial to further assess dazukibart in dermatomyositis and polymyositis. Dr. Fernandez said, “This is a story you should pay attention to if you treat any dermatomyositis patients at all.”

Regarding these emerging therapies for CLE and dermatomyositis, “This looks very much like the early days of psoriasis, in the early 2000s, when there was a lot of activity developing treatments,” Dr. Fernandez said. “I will predict that within 10 years, we will have multiple novel agents available that will probably work better than anything we have today.”

Dr. Fernandez reported receiving grant and/or research support from Alexion, Incyte, Mallinckrodt Pharmaceuticals, Novartis, Pfizer, and Priovant Therapeutics; acting as a consultant or advisory board member for AbbVie, Biogen, Mallinckrodt Pharmaceuticals; and being a member of the speaker bureau or receiving honoraria for non-CME from AbbVie, Kyowa Kirin, and Mallinckrodt Pharmaceuticals.

ORLANDO, FLORIDA — Advances in treating medical conditions rarely emerge in a straight line. Oftentimes, progress comes in fits and starts, and therapies to treat cutaneous lupus erythematosus (CLE) and dermatomyositis are no exception.

Beyond approved treatments that deserve more attention, like belimumab, approved by the Food and Drug Administration (FDA) for systemic lupus erythematosus (SLE) in 2011, and Octagam 10%, an intravenous immune globulin (IVIG) preparation approved for dermatomyositis in 2021, anticipation is growing for emerging therapies and their potential to provide relief to patients, Anthony Fernandez, MD, PhD, said at the ODAC Dermatology, Aesthetic & Surgical Conference. The tyrosine kinase 2 (TYK2) inhibitor deucravacitinib, Janus kinase (JAK) inhibitors brepocitinib and baricitinib, and the monoclonal antibody anifrolumab, he noted, are prime examples.

“There have been significant advances in the development of treatments for lupus erythematosus and dermatomyositis. In my opinion, this is the start of what will be the most exciting decade in the history of these two diseases,” said Dr. Fernandez, director of medical dermatology at the Cleveland Clinic.
 

Emerging Treatments for Cutaneous Lupus

Although SLE can involve many organ systems, the skin is one of the most affected. There are specific cutaneous lesions categorized as either acute cutaneous lupus, subacute cutaneous lupus, or chronic cutaneous lupus.

The oral TYK2 inhibitor deucravacitinib, for example, should be able to dampen interleukin responses in people with CLE, Dr. Fernandez said. Deucravacitinib was approved by the FDA to treat psoriasis in September 2022.

Cleveland Clinic Foundation

A phase 2 study published in 2023 focused on this agent for relief of systemic lupus. Improvements in cutaneous disease were a secondary endpoint. The trial demonstrated that the patients treated with deucravacitinib achieved a 56%-70% CLASI-50 response, depending on dosing, compared with a 17% response among those on placebo at week 48.

Based on the trial results, recruitment has begun for a phase 2 trial to evaluate deucravacitinib, compared with placebo, in patients with discoid and/or subacute cutaneous lupus. “This may be another medicine we have available to give to any of our patients with cutaneous lupus,” Dr. Fernandez said.
 

Anifrolumab Appears Promising

The FDA approval of anifrolumab, a type I interferon (IFN) receptor antagonist, for treating moderate to severe SLE in July 2021, for example, is good news for dermatologists and their patients, added Dr. Fernandez. “Almost immediately after approval, case studies showed marked improvement in patients with refractory cutaneous lupus.” While the therapy was approved for treating systemic lupus, it allows for off-label treatment of the cutaneous predominant form of the disease, he said.

Furthermore, the manufacturer of anifrolumab, AstraZeneca, is launching the LAVENDER clinical trial to assess the monoclonal antibody specifically for treating CLE. “This is a big deal because we may be able to prescribe anifrolumab for our cutaneous lupus patients who don’t have systemic lupus,” Dr. Fernandez said.

ORLANDO, FLORIDA — There are subtleties and nuances to diagnosing, treating, and monitoring the progress of treatment of hair loss in children. Moreover, hair loss in children can be challenging because it can be caused by a range of conditions, some common and others relatively rare.

Michelle Oboite, MD, shared tips on how to distinguish types of hair loss, when to treat with medications such as topical corticosteroids or Janus kinase (JAK) inhibitors, and why shared decision-making is important, at the ODAC Dermatology, Aesthetic & Surgical Conference.

What these conditions share is that they can negatively affect the quality of life for a child or teenager when the condition leads to anxiety, teasing, or bullying. “It is very isolating to have this condition that everyone in the world can see that you have and judge you for it,” said Dr. Oboite, an attending physician in the dermatology section of Children’s Hospital of Philadelphia.

While alopecia areata, tinea capitis, and trichotillomania are more common, other causes of hair loss in children include androgenetic alopecia, primary scarring alopecias, such as central centrifugal cicatricial alopecia, and dissecting cellulitis. Others are lichen planopilaris and genetic conditions, including loose anagen syndrome, uncombable hair syndrome, and “something so rare” — it has no acronym — autosomal recessive hypotrichosis with recurrent skin vesicles, Dr. Oboite said.
 

Alopecia Areata

Alopecia areata can differ from child to child and can appear in different stages: A localized patch stage, a diffuse patchy stage, or alopecia universalis. In this last stage, the child has already lost most or all the hair on the scalp and eyebrows, as well as the eyelashes.

The decision to treat or not to treat, particularly in younger children, should be on the basis of shared decision-making between a healthcare provider and caregiver, said Dr. Oboite, who is also an assistant professor of clinical dermatology at the University of Pennsylvania, Philadelphia.

Some younger children may not experience any negative impact from the condition, so waiting until they are older is an option.

Also, consider the impact of treatment on a child. Some therapies require frequent blood draws for monitoring, and some topical therapies that are applied multiple times a day “can be very overwhelming” for young children, Dr. Oboite said.

Most children with alopecia areata are healthy and do not need extensive screening laboratory testing. However, one exception is if thyroid dysfunction, commonly associated with alopecia areata, is suspected.

For alopecia areata, Dr. Oboite recommends starting with topical therapies, either topical corticosteroids (as first line) or topical JAK inhibitors (either topical ruxolitinib or compounded topical tofacitinib, both off-label for this indication).

Topical corticosteroids can be effective, but “you want to be thoughtful of the strength you’re using, the application frequency, and then the total amount of surface area that you’re treating,” Dr. Oboite said. Too potent or too much of a topical corticosteroid increases the risk for atrophy and systemic absorption, respectively. To reduce the risk, she reserves the use of ultrahigh-potency topical corticosteroids, such as clobetasol, for children ages 10 years or older. For children younger than 10 years, she recommends using mid-high-potency topical corticosteroids instead.

She recommends once-a-day application around bedtime 5 days a week, generally Monday through Friday to make it easier to remember.

“For children who have over 50% of the scalp involved, I do consider systemic therapy,” Dr. Oboite said. This can include oral steroids such as dexamethasone, prednisone, or prednisolone. For children with recalcitrant disease, she is more likely to use the oral JAK inhibitor ritlecitinib because it was recently approved by the Food and Drug Administration for treating severe alopecia areata in children 12 years and older and in adults.

Another strategy Dr. Oboite uses is to add low-dose oral minoxidil as an adjuvant to other systemic therapy. “I find that it helps with faster hair regrowth,” she said.
 

Tinea Capitis

Oral treatment is indicated for tinea capitis. “Topicals just don’t really clear this,” Dr. Oboite said. Also, talk to patients and families about preventing reinfection with the dermatophyte that causes this condition. “Make sure we’re cleaning hats, combs, brushes, and pillowcases. That is really important.”

Some patients can develop a widespread rash while on treatment. But in most cases, it’s not an adverse reaction to the medication but rather an indication that the body’s response is revving up, she noted.

Griseofulvin 20 mg/kg/d is one treatment option. Another is terbinafine (using weight-based dosing). A tip with terbinafine is that because the tablet needs to be crushed for a young child, “you can put it in anything, besides applesauce or yogurt with fruit on the bottom, which can be acidic and reduce the effectiveness of the medication,” Dr. Oboite said.

For cases of severe, inflammatory tinea capitis such as a kerion, “I will say you have to hold the hands of these patients, the journey can be long,” she added.
 

Trichotillomania

Trichotillomania occurs when someone cannot stop pulling their own hair, and in the early phases, it can be confused with alopecia areata. A thorough history and examination of the patient can help distinguish the two conditions. Sometimes a child or teen has a history of anxiety-related behaviors like nail biting that points to trichotillomania. Another tip is to use a dermatoscope to help distinguish hair loss conditions because it avoids having to do as many biopsies in children.

Redirection therapy can work for younger children, and cognitive behavioral therapy (CBT) can help older children with trichotillomania. In response to a question during the Q&A period, Dr. Oboite said psychiatrists or psychologists can perform CBT. If it takes time to get an appointment, there are some CBT apps that can help in the meantime, she said.

“One thing really important is to not blame the child,” Dr. Oboite said. “Most children don’t even know that they’re doing this. This is often not a behavior that is being done on purpose.”

Androgenetic Alopecia

Rarely, children and teenagers can also present with androgenetic alopecia, which Dr. Oboite has successfully treated with topical minoxidil, applied once a day before increasing to twice a day if tolerated. “I will tell them that when they pick it up, it will say ‘you should not use in children.’ But it actually can be used in children safely.”

Low-dose oral minoxidil is another option. Both treatments require a commitment by patients and parents because they are “taking this for a long time.”
 

Loose Anagen and Uncombable Hair Syndromes

A rare genetic form of hair loss is called loose anagen syndrome. Children with this disorder will have thin hair that is easily pulled out without a lot of force. Their hair appears to typically only grow to a certain length (such as to the nape of the neck) and then stops.

Another genetic hair loss condition is uncombable hair syndrome. It can cause hair to grow out of the scalp in all directions, and as the name suggests, it is almost impossible to comb or brush down. Along with loose anagen syndrome, uncombable hair syndrome tends to improve as the child gets older. “The key point here is telling parents that it can get better with time,” Dr. Oboite said.
 

A Condition With No Well-Known Acronym

She described a child she treated who had hair that never grew and was easily broken. The patient’s skin was prone to bruising, and her fingernails would easily fall off after trauma; her dentist noted that she had no buds for adult teeth on x-rays. These different presentations are important because hair, teeth, and nails all come from the same ectoderm germ line in embryo development, Dr. Oboite said.

Exome sequencing revealed the girl had a very rare diagnosis called autosomal recessive hypotrichosis with recurrent skin vesicles. “So, it is really important to recognize that children who are presenting with hair issues can have a genetic, underlying condition,” she said. Examining the skin, nails, and teeth, in addition to the hair, can be clues to these very rare diagnoses.

Some of these hair loss conditions in children can be challenging to diagnose and manage, Dr. Oboite said. “So don’t be afraid to ask for help on complex or rare cases.” Pediatric dermatologists “are always happy to help you. Hair loss is daunting, and hair loss in children can be even more daunting,” but the rewards of accurate diagnosis and successful treatment can be great, she said.

Dr. Oboite reported no relevant financial relationships.

Topical corticosteroids can be effective, but “you want to be thoughtful of the strength you’re using, the application frequency, and then the total amount of surface area that you’re treating,” Dr. Oboite said. Too potent or too much of a topical corticosteroid increases the risk for atrophy and systemic absorption, respectively. To reduce the risk, she reserves the use of ultrahigh-potency topical corticosteroids, such as clobetasol, for children ages 10 years or older. For children younger than 10 years, she recommends using mid-high-potency topical corticosteroids instead.

She recommends once-a-day application around bedtime 5 days a week, generally Monday through Friday to make it easier to remember.

“For children who have over 50% of the scalp involved, I do consider systemic therapy,” Dr. Oboite said. This can include oral steroids such as dexamethasone, prednisone, or prednisolone. For children with recalcitrant disease, she is more likely to use the oral JAK inhibitor ritlecitinib because it was recently approved by the Food and Drug Administration for treating severe alopecia areata in children 12 years and older and in adults.

Another strategy Dr. Oboite uses is to add low-dose oral minoxidil as an adjuvant to other systemic therapy. “I find that it helps with faster hair regrowth,” she said.
 

Tinea Capitis

Oral treatment is indicated for tinea capitis. “Topicals just don’t really clear this,” Dr. Oboite said. Also, talk to patients and families about preventing reinfection with the dermatophyte that causes this condition. “Make sure we’re cleaning hats, combs, brushes, and pillowcases. That is really important.”

Some patients can develop a widespread rash while on treatment. But in most cases, it’s not an adverse reaction to the medication but rather an indication that the body’s response is revving up, she noted.

Griseofulvin 20 mg/kg/d is one treatment option. Another is terbinafine (using weight-based dosing). A tip with terbinafine is that because the tablet needs to be crushed for a young child, “you can put it in anything, besides applesauce or yogurt with fruit on the bottom, which can be acidic and reduce the effectiveness of the medication,” Dr. Oboite said.

For cases of severe, inflammatory tinea capitis such as a kerion, “I will say you have to hold the hands of these patients, the journey can be long,” she added.
 

Trichotillomania

Trichotillomania occurs when someone cannot stop pulling their own hair, and in the early phases, it can be confused with alopecia areata. A thorough history and examination of the patient can help distinguish the two conditions. Sometimes a child or teen has a history of anxiety-related behaviors like nail biting that points to trichotillomania. Another tip is to use a dermatoscope to help distinguish hair loss conditions because it avoids having to do as many biopsies in children.

Redirection therapy can work for younger children, and cognitive behavioral therapy (CBT) can help older children with trichotillomania. In response to a question during the Q&A period, Dr. Oboite said psychiatrists or psychologists can perform CBT. If it takes time to get an appointment, there are some CBT apps that can help in the meantime, she said.

“One thing really important is to not blame the child,” Dr. Oboite said. “Most children don’t even know that they’re doing this. This is often not a behavior that is being done on purpose.”

Androgenetic Alopecia

Rarely, children and teenagers can also present with androgenetic alopecia, which Dr. Oboite has successfully treated with topical minoxidil, applied once a day before increasing to twice a day if tolerated. “I will tell them that when they pick it up, it will say ‘you should not use in children.’ But it actually can be used in children safely.”

Low-dose oral minoxidil is another option. Both treatments require a commitment by patients and parents because they are “taking this for a long time.”
 

Loose Anagen and Uncombable Hair Syndromes

A rare genetic form of hair loss is called loose anagen syndrome. Children with this disorder will have thin hair that is easily pulled out without a lot of force. Their hair appears to typically only grow to a certain length (such as to the nape of the neck) and then stops.

Another genetic hair loss condition is uncombable hair syndrome. It can cause hair to grow out of the scalp in all directions, and as the name suggests, it is almost impossible to comb or brush down. Along with loose anagen syndrome, uncombable hair syndrome tends to improve as the child gets older. “The key point here is telling parents that it can get better with time,” Dr. Oboite said.
 

A Condition With No Well-Known Acronym

She described a child she treated who had hair that never grew and was easily broken. The patient’s skin was prone to bruising, and her fingernails would easily fall off after trauma; her dentist noted that she had no buds for adult teeth on x-rays. These different presentations are important because hair, teeth, and nails all come from the same ectoderm germ line in embryo development, Dr. Oboite said.

Exome sequencing revealed the girl had a very rare diagnosis called autosomal recessive hypotrichosis with recurrent skin vesicles. “So, it is really important to recognize that children who are presenting with hair issues can have a genetic, underlying condition,” she said. Examining the skin, nails, and teeth, in addition to the hair, can be clues to these very rare diagnoses.

Some of these hair loss conditions in children can be challenging to diagnose and manage, Dr. Oboite said. “So don’t be afraid to ask for help on complex or rare cases.” Pediatric dermatologists “are always happy to help you. Hair loss is daunting, and hair loss in children can be even more daunting,” but the rewards of accurate diagnosis and successful treatment can be great, she said.

Dr. Oboite reported no relevant financial relationships.

ORLANDO, FLORIDA — Amid all the hype, claims, and confusion, there is evidence linking some foods and drinks to an increased risk for acne, psoriasis, atopic dermatitis, rosacea, and other common skin conditions. So, what is the connection in each case? And how can people with any of these skin conditions potentially improve their health and quality of life with dietary changes?

Acne

One of the major areas of interest is diet and acne. “We’ve all heard sugar and dairy are bad, and the Western diet is high in sugar and dairy,” Dr. Shi said at the ODAC Dermatology, Aesthetic & Surgical Conference.
Dairy, red meat, and carbohydrates can break down into leucine, an essential amino acid found in protein. Leucine and sugar together, in turn, can produce insulin and insulin-like growth factor 1 (IGF-1), which, through different pathways, can reach the androgen receptors throughout the body, including the skin. This results in sebogenesis, lipogenesis, and keratinization, which triggers follicular inflammation and results in more of the acne-causing bacteria Cutibacterium acnes. 
Milk and other dairy products also can increase IGF-1 levels, which can alter hormonal mediators and increase acne.
Not all types of dairy milk are created equal, however, when it comes to acne. Dr. Shi wondered why 2% milk has overall color and nutritional content very similar to that of whole milk. “I looked into this.” She discovered that when milk manufacturers remove the fat, they often add whey proteins to restore some nutrients. Whey protein can increase acne, Dr. Shi added. 
“So, if you’re going to choose any milk to drink, I think from an acne perspective, it’s better to use whole milk. If you can get it organic, even better.” Skim milk is the most acnegenic, she said.

Psoriasis

A systematic review of 55 studies evaluating diet and psoriasis found obesity can be an exacerbating factor. The strongest evidence for dietary weight reduction points to a hypocaloric diet in people with overweight or obesity, according to the review. Other evidence suggests alcohol can lower response to treatment and is linked with more severe psoriasis. Furthermore, a gluten-free diet or vitamin D supplements can help some subpopulations of people with psoriasis. 
“An overwhelming majority of our psoriasis patients are vitamin D deficient,” Dr. Shi said. 
The National Psoriasis Foundation (NPF) publishes dietary modification guidelines, updated as recently as November 2023. The NPF states that “there is no diet that will cure psoriatic disease, but there are many ways in which eating healthful food may lessen the severity of symptoms and play a role in lowering the likelihood of developing comorbidities.”
Healthier choices include fruits, vegetables, whole grains, and fat-free or low-fat dairy products. Include lean meats, poultry, fish, beans, eggs, and nuts. Adherence to a Mediterranean diet has been linked to a lower severity of psoriasis.

Atopic Dermatitis

Atopic dermatitis (AD) is “one of the prototypical diseases related to diet,” Dr. Shi said. A different meta-analysis looked at randomized controlled trials of synbiotics (a combination of prebiotics and probiotics) for treatment of AD.
These researchers found that synbiotics do not prevent AD, but they can help treat it in adults and children older than 1 year. In addition, synbiotics are more beneficial than probiotics in treating the condition, although there are no head-to-head comparison studies. In addition, the meta-analysis found that prebiotics alone can lower AD severity.
However, Dr. Shi said, there are no recommendations from the American Academy of Dermatology (AAD) on prebiotics or probiotics for AD, and the AAD does not recommend any supplement or essential oil for AD.
In a 2022 review, investigators ranked the efficacy of different supplements for AD based on available evidence. They found the greatest benefit associated with vitamin D supplementation, followed by vitamin E, probiotics, hemp seed oil, histidine, and oolong tea. They also noted the ‘Six Food Elimination Diet and Autoimmune Protocol’ featured the least amount of evidence to back it up. 

Rosacea

Rosacea appears to be caused by “all the fun things in life” like sunlight, alcohol, chocolate, spicy foods, and caffeine, Dr. Shi said. In people with rosacea, they can cause facial flushing, edema, burning, and an inflammatory response.
Certain foods can activate skin receptors and sensory neurons, which can release neuropeptides that act on mast cells in blood that lead to flushing. The skin-gut axis may also be involved, evidence suggests. “And that is why food has a pretty profound impact on rosacea,” Dr. Shi said. 
Dr. Shi reported no relevant financial relationships.

You may have never heard of it, but you may have had it. More evidence points to “long flu” being a real phenomenon, with a large study showing symptoms persist at least 4 weeks or more after some people are hospitalized for the flu.

Researchers compared long flu to long COVID-19 and found long flu happened less often and was less severe overall. This difference could be because the flu mostly affects the lungs whereas COVID can affect any number of organ systems in the body.

The investigators were surprised that both long flu and long COVID were linked to a greater burden of health loss, compared to either initial infection.

“I think COVID and long COVID made us realize that infections have long-term consequences, and often the toll of those long-term consequences is much larger than the toll of acute disease,” said Ziyad Al-Aly, MD, senior author of the study and chief of research and development at the VA St. Louis Health Care System.

“I know, having studied long COVID for the past 4 years, I should not be surprised. But I am in awe of what these infections can do to the long-term health of affected individuals,” said Dr. Al-Aly, who is also a clinical epidemiologist at Washington University in St. Louis.

Dr. Al-Aly and colleagues Yan Xie, PhD, and Taeyoung Choi, MS, analyzed US Department of Veterans Affairs medical records. They compared 81,280 people hospitalized with COVID to 10,985 people hospitalized with the flu before the COVID pandemic. They checked up to 18 months after initial infections to see who developed long flu or long COVID symptoms.

The study was published online in The Lancet Infectious Diseases.

It’s an interesting study, said Aaron E. Glatt, MD, chairman of the Department of Medicine and a hospital epidemiologist at Mount Sinai South Nassau in Oceanside, NY, who was not part of the research.

“There is a concern with many viruses that you can have long-term consequences,” said Dr. Glatt, who is also a fellow of the Infectious Diseases Society of America. He said the possibility of long-term symptoms with the flu is not new, “but it’s nice to have more data.”

People hospitalized with COVID had a 50% higher risk of death during the study period than people hospitalized with the flu. Put another way, for every 100 people admitted to the hospital with COVID, about eight more died than those hospitalized with the flu over the following 18 months. Hospital admissions and admissions to the intensive care unit were also higher in the long COVID group — 20 more people and nine more people, respectively, for every 100 people admitted to the hospital with COVID.

More research is needed, Dr. Glatt said. “With many of these viruses, we don’t understand what they do to the body.” A prospective study to see if antiviral treatments make a difference, for example, would be useful, he noted.

Dr. Al-Aly and colleagues would like to do more studies.

“We need to more deeply understand how and why acute infections cause long-term illness,” he said, noting that he also wants to investigate ways to prevent and treat the long-term effects.

“Much remains to be done, and we are deeply committed to doing our best to develop those answers.”

VANCOUVER — Glucagon-like peptide-1 (GLP-1) agonists, like semaglutide, liraglutide, and the newly US Food and Drug Administration–approved tirzepatide, not only are gaining popularity among the public for weight loss but also are the focus of considerable attention from gastroenterology researchers.

The robust interest in GLP-1 agonists was on full display here at the annual meeting of the American College of Gastroenterology, with investigators sharing results on which agent is most effective for weight loss, how they compare to bariatric surgery for weight loss or prevention of metabolic dysfunction–associated steatotic liver disease, and their potential role to prevent regain after weight-loss surgery.
 

Head-to-Head Comparison

Tirzepatide 15 mg emerged as superior to other GLP-1 agonists for weight loss, for example, in a network meta-analysis of randomized controlled trials looking into obesity management.

Tirzepatide 15 mg was associated with the most effective mean weight loss at just over 15% when Jena Velji-Ibrahim, MD, and colleagues combined data from 14 studies with 18,714 participants with overweight or obesity but without diabetes.

Next up in order of weight-loss efficacy was tirzepatide 10 mg with 13% mean weight loss, semaglutide 2.4 mg with just over 11% mean weight loss, and tirzepatide 5 mg with almost 10% mean weight loss. The only outlier was dulaglutide 0.75 mg, which was linked to about 8% weight gain.

“While clinical trials have been conducted to assess the weight-loss efficacy of GLP-1 agonists, there has been limited head-to-head comparisons, and the data that has been obtained has been quite inconsistent,” Dr. Velji-Ibrahim said when presenting results at the meeting.

Researchers found little difference in efficacies between tirzepatide 15 mg and 10 mg, suggesting both are a viable option for weight loss, said Dr. Velji-Ibrahim of Prisma Health Greenville Memorial Hospital and University of South Carolina School of Medicine in Greenville.

She also reported similar efficacies between oral semaglutide 50 mg and subcutaneous semaglutide 2.4 mg, “meaning that we have another option for weight management.”

Side effects among the different GLP-1 agonists, and among the same agent at different doses, were not significantly different.
 

Comparison With Bariatric Surgery for Reducing Major Adverse Cardiovascular Events (MACE)

For many years, bariatric surgeons have pointed to the health benefits of weight-loss surgery in the right candidates, including a reduced risk for adverse cardiovascular events.

The weight loss associated with GLP-1 agonists has likewise shown benefits in reducing MACE. However, it remains unclear if one of these weight-loss strategies is better than the other in reducing these outcomes.

To determine this, researchers compared 118,828 people who had bariatric surgery to another propensity-matched group of 118,828 others prescribed GLP-1 agonists. They included adults with a body mass index (BMI) of 35 or higher in the national TriNetX database.

The multicenter, retrospective study revealed bariatric surgery was superior in reducing the risk for heart failure, MACE, and cerebrovascular disease at 3, 5, 7, and 10 years. At 10 years, for example, bariatric surgery was associated with 31% fewer composite cardiovascular events than the GLP-1 agonists.

“Our results suggest that bariatric surgery is more effective than GLP-1 analogs in preventing adverse cardiovascular events in obese patients,” Ayowumi A. Adekolu, MD, an internal medicine resident at West Virginia School of Medicine in Morgantown, said in audio comments accompanying his ePoster at the meeting. “Although these findings highlight the benefit of bariatric surgery in mitigating adverse cardiovascular events, well-designed prospective studies are necessary to confirm these benefits in this patient population.”

Possible Role in Fatty Liver Disease Prevention
 

In another large multicenter study from the same institution, Ethan M. Cohen, MD, along with co-author Dr. Adekolu and others, compared the effectiveness of bariatric surgery to GLP-1 agonists for preventing nonalcoholic fatty liver disease (NAFLD). Since the study was conducted, the official name of NAFLD has changed to metabolic dysfunction–associated steatotic liver disease.

Dr. Cohen and colleagues evaluated data from the TriNetX database and included adults with a BMI of 35 or higher. They propensity matched 124,022 people who had sleeve gastrectomy or Roux-en-Y gastric bypass to another 124,022 others prescribed GLP-1 agonists. Again, they looked at outcomes at 3, 5, 7, and 10 years.

They found bariatric surgery superior to GLP-1 agonists for reducing the risk of developing NAFLD. Relative risk reduction was 25% at 3 years, 28% at 5 years, 27% at 7 years, and 26% at 10 years.

Although not to the same extent as surgery in this study, GLP-1–associated weight loss did reduce risks as well.

“An important aspect of this is that for some of these people, bariatric surgery is not even an option,” Dr. Cohen said in an interview, citing as an example those who do not meet the criteria for surgery.

Dr. Cohen and colleagues plan to continue the study with a larger number of participants.
 

Real-World Weight Regain

In another instance where a surgical procedure trumped GLP-1 agonists, revisional endoscopic sleeve gastroplasty (ESG) offered significantly higher weight loss than GLP-1 agonists among people who regained weight following initial weight-loss surgery, according to a case-control real-world study presented at the meeting.

“Laparoscopic sleeve gastrectomy [LSG] is a frequently performed bariatric surgery worldwide resulting in significant weight loss and improvement in obesity-related comorbidities,” said Firas Bahdi, MD, gastroenterology fellow at the David Geffen School of Medicine at University of California, Los Angeles. “Despite its success, around one third of patients, unfortunately, develop weight regain warranting intervention.”

Dr. Bahdi and colleagues retrospectively studied 68 adults prescribed subcutaneous semaglutide or tirzepatide after LSG, another 20 who had ESG for weight regain after LSG, and 87 controls with intact stomachs who also took GLP-1 agonists for weight loss.

They found that the ESG group experienced a significantly higher percentage of total body weight loss at 3 months than the GLP-1 group (10% vs 4.3%, respectively; P = .0001). Similarly, at the 6-month follow-up, the ESG group experienced 11.5% total body weight loss compared to 6.8% in the GLP-1 group (P = .03).

The GLP-1 after LSG group still fared better than the GLP-1 control group of people who never had surgery. Total body weight loss was 4.3% vs 5.7% at 3 months (P = .02), 6.8% vs 9.2% at 6 months (P = .02), and 9.2% vs 12.7% at 12 months (P = .03).

“In this real-world experience, revisional ESG offers significantly more weight loss than GLP-1 agonists for patients with weight regain, while also avoiding the challenges of medication refills, making it an attractive option,” Dr. Bahdi said.

Future multicenter studies are warranted to confirm these results and explore physiological explanations, he added.

The study received an Outstanding Research Award in the Obesity Category (Trainee).

Dr. Velji-Ibrahim, Dr. Adekolu, Dr. Cohen, and Dr. Bahdi indicated no relevant financial relationships.

VANCOUVER — Glucagon-like peptide-1 (GLP-1) agonists, like semaglutide, liraglutide, and the newly US Food and Drug Administration–approved tirzepatide, not only are gaining popularity among the public for weight loss but also are the focus of considerable attention from gastroenterology researchers.

The robust interest in GLP-1 agonists was on full display here at the annual meeting of the American College of Gastroenterology, with investigators sharing results on which agent is most effective for weight loss, how they compare to bariatric surgery for weight loss or prevention of metabolic dysfunction–associated steatotic liver disease, and their potential role to prevent regain after weight-loss surgery.
 

Head-to-Head Comparison

Tirzepatide 15 mg emerged as superior to other GLP-1 agonists for weight loss, for example, in a network meta-analysis of randomized controlled trials looking into obesity management.

Tirzepatide 15 mg was associated with the most effective mean weight loss at just over 15% when Jena Velji-Ibrahim, MD, and colleagues combined data from 14 studies with 18,714 participants with overweight or obesity but without diabetes.

Next up in order of weight-loss efficacy was tirzepatide 10 mg with 13% mean weight loss, semaglutide 2.4 mg with just over 11% mean weight loss, and tirzepatide 5 mg with almost 10% mean weight loss. The only outlier was dulaglutide 0.75 mg, which was linked to about 8% weight gain.

“While clinical trials have been conducted to assess the weight-loss efficacy of GLP-1 agonists, there has been limited head-to-head comparisons, and the data that has been obtained has been quite inconsistent,” Dr. Velji-Ibrahim said when presenting results at the meeting.

Researchers found little difference in efficacies between tirzepatide 15 mg and 10 mg, suggesting both are a viable option for weight loss, said Dr. Velji-Ibrahim of Prisma Health Greenville Memorial Hospital and University of South Carolina School of Medicine in Greenville.

She also reported similar efficacies between oral semaglutide 50 mg and subcutaneous semaglutide 2.4 mg, “meaning that we have another option for weight management.”

Side effects among the different GLP-1 agonists, and among the same agent at different doses, were not significantly different.
 

Comparison With Bariatric Surgery for Reducing Major Adverse Cardiovascular Events (MACE)

For many years, bariatric surgeons have pointed to the health benefits of weight-loss surgery in the right candidates, including a reduced risk for adverse cardiovascular events.

The weight loss associated with GLP-1 agonists has likewise shown benefits in reducing MACE. However, it remains unclear if one of these weight-loss strategies is better than the other in reducing these outcomes.

To determine this, researchers compared 118,828 people who had bariatric surgery to another propensity-matched group of 118,828 others prescribed GLP-1 agonists. They included adults with a body mass index (BMI) of 35 or higher in the national TriNetX database.

The multicenter, retrospective study revealed bariatric surgery was superior in reducing the risk for heart failure, MACE, and cerebrovascular disease at 3, 5, 7, and 10 years. At 10 years, for example, bariatric surgery was associated with 31% fewer composite cardiovascular events than the GLP-1 agonists.

“Our results suggest that bariatric surgery is more effective than GLP-1 analogs in preventing adverse cardiovascular events in obese patients,” Ayowumi A. Adekolu, MD, an internal medicine resident at West Virginia School of Medicine in Morgantown, said in audio comments accompanying his ePoster at the meeting. “Although these findings highlight the benefit of bariatric surgery in mitigating adverse cardiovascular events, well-designed prospective studies are necessary to confirm these benefits in this patient population.”

Possible Role in Fatty Liver Disease Prevention
 

In another large multicenter study from the same institution, Ethan M. Cohen, MD, along with co-author Dr. Adekolu and others, compared the effectiveness of bariatric surgery to GLP-1 agonists for preventing nonalcoholic fatty liver disease (NAFLD). Since the study was conducted, the official name of NAFLD has changed to metabolic dysfunction–associated steatotic liver disease.

Dr. Cohen and colleagues evaluated data from the TriNetX database and included adults with a BMI of 35 or higher. They propensity matched 124,022 people who had sleeve gastrectomy or Roux-en-Y gastric bypass to another 124,022 others prescribed GLP-1 agonists. Again, they looked at outcomes at 3, 5, 7, and 10 years.

They found bariatric surgery superior to GLP-1 agonists for reducing the risk of developing NAFLD. Relative risk reduction was 25% at 3 years, 28% at 5 years, 27% at 7 years, and 26% at 10 years.
