SAN DIEGO — Transmasculine patients with acne require unique care that not only is sensitive but also reflects an understanding about factors that can affect their skin such as hormone therapy, a dermatologist told colleagues in a session at the American Academy of Dermatology annual meeting.

In these patients, treatment of acne is crucial, said Howa Yeung, MD, MSc, assistant professor of dermatology, Emory University, Atlanta. “These are patients who are suffering and reporting that they’re having mental health impacts” related to acne.

In transmasculine patients — those who were biologically female at birth but identify as masculine — testosterone therapy greatly boosts the risk for acne, even in adults who are long past adolescence, Dr. Yeung said. Data suggest that acne appears within the first 6 months after testosterone therapy begins, he said, “and the maximal and complete effect occurs within 1-2 years.”

A 2021 study tracked 988 transgender patients receiving testosterone at Fenway Health in Boston and found that 31% had a diagnosis of acne, up from 6.3% prior to taking hormones. And 2 years following the start of therapy, 25.1% had acne, with cases especially common among those aged 18-20.75 years (29.6%). Even among those aged 28.25-66.5 years, 17.1% had acne.

Transmasculine patients may develop acne in areas across the body “in places that you normally won’t see by just looking at the patient,” Dr. Yeung said. Excoriation in addition to comedones, papules, pustules, and nodules can be common, he added.

Dr. Yeung highlighted a 2019 study of transgender men that linked higher levels of acne to higher levels of serum testosterone, higher body mass index, and current smoking. And in a 2014 study, 6% of 50 transmasculine patients had moderate to severe acne after an average of 10 years on testosterone therapy.

A 2020 study of 696 transgender adults surveyed in California and Georgia found that 14% of transmasculine patients had moderate to severe acne — two thirds attributed it to hormone therapy — vs 1% of transfeminine patients, said Dr. Yeung, the lead author of the study. However, transmasculine patients were less likely to have seen a dermatologist.

Dr. Yeung also highlighted a 2021 study he coauthored that linked current moderate to severe acne in transmasculine patients taking testosterone to higher levels of depression and anxiety vs counterparts who had never had those forms of acne.

Another factor affecting acne in transmasculine patients is the use of chest binders to reduce breast size. “Wearing a chest binder is really helpful for a lot of our patients and is associated with improved self-esteem, mood, mental health, and safety in public,” Dr. Yeung said. However, the binders can contribute to skin problems.

Dr. Yeung said he and his colleagues emphasize the importance of breathable material in binders and suggest to patients that they not wear them when they’re in “safe spaces.”

Isotretinoin, Contraception Considerations

As for treatment of acne in transgender patients, Dr. Yeung cautioned colleagues to not automatically reject isotretinoin as an option for transgender patients who have a history of depression. Dermatologists may be tempted to avoid the drug in these patients because of its link to suicide, he said. (This apparent association has long been debated.) But, Dr. Yeung said, it’s important to consider that many of these patients suffered from anxiety and depression because of the lack of access to proper gender-reassignment treatment.

When using isotretinoin, he emphasized, it’s crucial to consider whether transmasculine patients could become pregnant while on this therapy. Consider whether the patient has the organs needed to become pregnant and ask questions about the potential that they could be impregnated.

“Remember that sexual behavior is different from gender identity,” Dr. Yeung said. A transmasculine person with a uterus and vagina, for example, may still have vaginal intercourse with males and potentially become pregnant. “So, we need to assess what kind of sexual behavior our patients are taking part in.”

Contraceptives such as intrauterine devices, implants, and injectable options may be helpful for transmasculine patients because they can reduce menstrual symptoms like spotting that can be distressing to them, he said. By helping a patient take a contraceptive, “you may actually be helping with their gender dysphoria and helping them get on isotretinoin.”

Dr. Yeung disclosed fees from JAMA and American Academy of Dermatology; grants/research funding from the American Acne & Rosacea Society, Dermatology Foundation, Department of Veterans Affairs, National Eczema Association, and National Institutes of Health; and speaker/faculty education honoraria from Dermatology Digest.

SAN DIEGO — After 24 weeks of treatment with subcutaneously administered sonelokimab 120 mg, about 43% of patients with moderate to severe hidradenitis suppurativa (HS) achieved a Hidradenitis Suppurativa Clinical Response (HiSCR75), defined as at least a 75% reduction in total abscess and inflammatory nodule (AN) count with no increase in abscess or draining tunnel count relative to baseline, results from a randomized clinical trial showed.

Sonelokimab is a novel humanized nanobody that selectively binds to interleukin (IL)-17A and IL-17F, presenting author Brian Kirby, MD, a dermatologist at St. Vincent’s Private Hospital, Dublin, Ireland, said during a late-breaking abstract session at the annual meeting of the American Academy of Dermatology. Sonelokimab is smaller than traditional monoclonal antibodies, he said, “which means it may be able to penetrate tissues better and stay there longer.” It is being developed by MoonLake Immunotherapeutics, based in Zug, Switzerland

According to a press release from the company, nanobodies represent a new generation of targeted therapies derived from antibodies. They consist of one or more domains based on the small antigen-binding variable regions of heavy-chain-only antibodies.

In a phase 2 study known as the MIRA trial, researchers recruited 234 patients with moderate to severe HS to evaluate two different doses of sonelokimab (120 mg and 240 mg every 2 weeks) with a placebo control arm and adalimumab as an active reference arm. The primary endpoint of was the percentage of participants who achieved a HiSCR75. The study population included adults with Hurley Stage II or III HS who had HS lesions in 2 or more anatomical areas and a total abscess and inflammatory nodule (AN) count of 5 or more lesions; and had been treated with 2 or fewer biologics.

Dr. Kirby reported results from 67 patients in the sonelokimab 120 mg arm, 66 in the sonelokimab 240 mg arm, and 39 in the placebo arm. “It’s worth noting that the baseline AN count ranged between 12 and nearly 15, the mean draining tunnel count ranged between 2.9 and 3.7, and between 7% and 13% of patients were on concomitant antibiotics,” he said.

At 24 weeks, 43.3% of patients in the sonelokimab 120 mg arm achieved a HiSCR 75, compared with 34.8% of those in the sonelokimab 240 mg arm and 14.7% of those in the placebo arm, he reported. Meanwhile, 65.7% of patients in the sonelokimab 120 mg arm achieved an HiSCR 75, compared with 53% of those in the sonelokimab 240 mg arm and 27.9% of those in the placebo arm. Discontinuation rates were low and similar between treatment arms, with fewer than 10% of patients failing to complete week 24 of treatment.

In other findings, 69% of patients in the 120 mg arm achieved a HiSCR 50 at week 24 compared with 60.3% in the 240 mg arm; 56.9% in the 120 mg arm achieved a HiSCR 75 compared with 37.9% in the 240 mg arm; and 37.9% in the 120 mg arm achieved a HiSCR 75 compared with 27.6% in the 240 mg arm.

In addition, complete inflammatory remission as defined by the International HS Severity Score System (IHS4-100) continued to increase to week 24, with 24.1% of patients in the 120 mg arm achieving complete remission, compared with 15.5% of those in the 240 mg arm. Meaningful improvements in quality of life, skin pain, and HS symptoms reported by patients treated with sonelokimab were maintained or increased to week 24. Specifically, more than 60% of patients had a meaningful clinical improvement in their Dermatology Life Quality Index, over 45% had a minimum of a 30% increase in the Numerical Rating Scale **30, and more than 41% of patients reported absent or minimal symptoms on the Patient’s Global Impression of their Disease Severity, “which is a high bar to achieve in HS,” Dr. Kirby said.
 

No Serious Safety Signals Noted

There were no unexpected safety signals to week 24. The incidence of treatment-related adverse events was low, and there were no cases of inflammatory bowel disease. There were no serious infections, no major adverse cardiovascular event (MACE) reports, and no significant abnormalities on liver function tests. “There were also no safety signals on suicidal behavior, attempted suicides, or completed suicides,” he said.

“As you would expect with in IL-17 inhibitor, there was a signal for candidiasis, but all cases were judged to be mild or moderate, and no cases led to discontinuation of treatment from the trial because of candidal infection.”

Based on these data, Dr. Kirby said that larger and longer-term phase 3 trials are planned to further examine the safety and efficacy of sonelokimab at the 120 mg dose for the treatment of moderate-to-severe HS.

One of the session moderators, Joel M. Gelfand, MD, professor of dermatology and epidemiology at the University of Pennsylvania, Philadelphia, asked Dr. Kirby why he thought the lower dose resulted in generally better outcomes compared with the higher dose.

“There were no statistically significant differences between the two groups,” Dr. Kirby responded. “The 120 mg dose we know is highly effective in psoriasis, so there may be a ceiling effect. This may also be due to population variability, but the bottom line is that the 120 mg dose performs extremely well.”

Dr. Kirby disclosed that he has received research support from/has been a principal investigator for several pharmaceutical companies, including MoonLake Immunotherapeutics. Dr. Gelfand reported that he has been a consultant to and/or a member of the data safety monitoring board member for several pharmaceutical companies, including MoonLake.

SAN DIEGO — Treatment with topical roflumilast, 0.05%, approved at a higher concentration for treating psoriasis, showed high levels of improvement in about a quarter of children aged 2-5 years with mild to moderate atopic dermatitis (AD), according to the results of a phase 3 study reported at the annual meeting of the American Academy of Dermatology.

Among patients treated with roflumilast cream, 0.05%, 25.4% reached the primary endpoint of “clear” or “almost clear” plus a two-grade improvement from baseline at week 4 vs 10.7% among those in the vehicle group (P < .0001) in a phase 3 randomized controlled trial of children. The findings were released in a late-breaker session at the meeting.

Roflumilast cream, 0.3% (Zoryve), is approved by the Food and Drug Administration (FDA) for treating psoriasis in patients 6 years and older, and lower doses are being evaluated for AD: 0.15% for adults and children ages 6 and older, and 0.05% for ages 2-5. Roflumilast is a phosphodiesterase-4 inhibitor. In 2023, the FDA accepted a supplemental drug application from the manufacturer, Arcutis, for roflumilast, 0.15%, for treating AD in patients ages 6 and older, based on the results from two recently published phase 3 trials, INTEGUMENT-1 and INTEGUMENT-2.

The study of younger children, INTEGUMENT-PED, recruited 652 patients aged 2-5 with mild to moderate AD, with a Validated Investigator Global Assessment scale for AD (vlGA-AD) score of 2 or 3, a mean body surface area of 22% overall (range, 3%-82%), and an Eczema Area and Severity Index (EASI) score of at least 5. Of the patients enrolled, 437 were assigned to 0.05% roflumilast cream, applied once a day for 4 weeks (mean age, 3.3 years; 51.6% male; 67.4% White; 15.6% Black; 8.5% Asian; 8.5% other or more than one race; 80.5% not Latino/Hispanic). The remaining 215 children were assigned to vehicle cream and had similar characteristics.

About 52% of the patients in both groups had an inadequate response, intolerance, or contraindications to topical corticosteroids (and about 17% for topical calcineurin inhibitors and about 9% for crisaborole).

The proportions of patients who reached “clear” (0) or “almost clear” (1) on the vlGA-AD scale were 35.4% and 14.6%, respectively, at week 4 (P < .0001) for roflumilast and vehicle, respectively, according to the lead author of the study, Lawrence M. Eichenfield, MD, professor of dermatology and pediatrics at the University of California, San Diego, who presented the results at the meeting. In addition, 39.4% and 20.6% achieved an EASI-75 (a secondary endpoint), respectively (P < .0001), and itch also improved within 24 hours of starting treatment.

With regard to safety, 29.7% of patients taking roflumilast had treatment-emergent adverse effects (including upper respiratory tract infections in 4.1%) vs 21.9% of those in the vehicle arm (including upper respiratory tract infections in 1.4%). Reports of pain at the administration site were low (1.6% for roflumilast vs 1.9% for vehicle). Only one patient, a 2-year-old girl, had a treatment-emergent serious adverse event. The child, who was in the roflumilast group, had cellulitis involving noneczematous skin and was treated with antibiotics in the hospital for 3 days. The event was not attributed to roflumilast, which was stopped for 5 days, according to Dr. Eichenfield.

In an interview, Fairfield, Connecticut–based dermatologist Brittany Craiglow, MD, who was not involved in the study, said topical roflumilast would be an “important” new treatment because there are still few nonsteroidal options for the treatment of AD in children under 12. “The excellent local tolerability combined with early improvements in itch and skin clearance will make this a particularly attractive option, if approved,” she said.

Dr. Eichenfield disclosed multiple relationships with various drugmakers. He and several other study authors are investigators and/or consultants for Arcutis and received grants/research funding and/or honoraria. Two authors are Arcutis employees. Other disclosure information for the authors was not immediately available. Dr. Craiglow had no disclosures.

SAN DIEGO — Treatment with topical roflumilast, 0.05%, approved at a higher concentration for treating psoriasis, showed high levels of improvement in about a quarter of children aged 2-5 years with mild to moderate atopic dermatitis (AD), according to the results of a phase 3 study reported at the annual meeting of the American Academy of Dermatology.

Among patients treated with roflumilast cream, 0.05%, 25.4% reached the primary endpoint of “clear” or “almost clear” plus a two-grade improvement from baseline at week 4 vs 10.7% among those in the vehicle group (P < .0001) in a phase 3 randomized controlled trial of children. The findings were released in a late-breaker session at the meeting.

Roflumilast cream, 0.3% (Zoryve), is approved by the Food and Drug Administration (FDA) for treating psoriasis in patients 6 years and older, and lower doses are being evaluated for AD: 0.15% for adults and children ages 6 and older, and 0.05% for ages 2-5. Roflumilast is a phosphodiesterase-4 inhibitor. In 2023, the FDA accepted a supplemental drug application from the manufacturer, Arcutis, for roflumilast, 0.15%, for treating AD in patients ages 6 and older, based on the results from two recently published phase 3 trials, INTEGUMENT-1 and INTEGUMENT-2.

The study of younger children, INTEGUMENT-PED, recruited 652 patients aged 2-5 with mild to moderate AD, with a Validated Investigator Global Assessment scale for AD (vlGA-AD) score of 2 or 3, a mean body surface area of 22% overall (range, 3%-82%), and an Eczema Area and Severity Index (EASI) score of at least 5. Of the patients enrolled, 437 were assigned to 0.05% roflumilast cream, applied once a day for 4 weeks (mean age, 3.3 years; 51.6% male; 67.4% White; 15.6% Black; 8.5% Asian; 8.5% other or more than one race; 80.5% not Latino/Hispanic).

SAN DIEGO — In published trials, both an interleukin (IL)–17 inhibitor and an IL-23 inhibitor achieved impressive rates of clear or almost clear responses in patients with moderate to severe plaque psoriasis, but late-breaker data presented at the annual meeting of the American Academy of Dermatology show that these types of responses are sustained for as long as patients have remained on therapy.

Of the two, the longer follow up is with the IL-17 inhibitor bimekizumab (Bimzelx). In a 4-year open-label extension study, the Psoriasis Area and Severity Index (PASI) 90 rate was approximately 85% in treated patients, according to Mark Lebwohl, MD, professor and chairman emeritus of the Department of Dermatology, Icahn School of Medicine at Mount Sinai in New York City

A PASI 90 score signifies that 90% of skin surface area is cleared. The proportion of patients who achieved a PASI 100 score, signifying total clearance, approached 70% at 4 years in the group with the greatest response. PASI 90 and PASI 100 rates at this point were only modestly lower than those reported at the end of the double-blind phase 3 trial when evaluated 3 years earlier. 

Follow-up with a novel oral anti-IL-23 inhibitor JNJ-2113 (JNJ-77242113) was only 52 weeks, far shorter. But again, the response for the most effective dose at the end of this period was essentially unchanged from that at 16 weeks. Among those on the highest and most effective test dose of once-daily 100 mg, the PASI 90 at 1 year was 64.3%, a rate that was essentially unchanged from week 16.

No Apparent Loss of Benefit Over Time

“We can really look at those dose-response curves and see that there is, overall, a maintenance of response,” reported Laura K. Ferris, MD, PhD, professor and director of clinical trials, Department of Dermatology, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania. In her presentation of the data, she showed similar sustained control for the most effective doses of JNJ-2113 for multiple clinical outcomes, including an investigator’s global assessment (IGA) score of 0 or 1, also signifying clear or near clear skin.

Bimekizumab, a monoclonal antibody that inhibits both IL-17A and IL-17F, is already approved for the treatment of plaque psoriasis. The 52-week BE SURE trial, which provided the 478 patients who entered into the BE BRIGHT open label extension study, was published in The New England Journal of Medicine in July 2021. 

In the 4-year data reported by Dr. Lebwohl, three groups were compared: Those initially randomized to an every-4-week dosing schedule of bimekizumab over the course of the 52-week BE SURE trial; those randomized to an every-4-week bimekizumab schedule who were then subsequently switched to an every-8-week schedule; and those initiated on the TNF-inhibitor adalimumab (Humira) and were then switched at week 24 to every-4-week bimekizumab.

The PASI 90 responses at 52 weeks in these three groups, respectively, were 91.2%, 89.3%, and 95.2%. At 4 years, this almost clear response was observed in 82.4%, 83.2%, and 87.6%, respectively. At 52 weeks, the PASI 100 responses in these three groups, respectively, were 75.3%, 74.2%, and 72.9%. At 4 years, 61.9%, 58.5%, and 69.5% still had complete skin clearance.

Bimekizumab was well tolerated during the randomized trial, reported Dr. Lebwohl. The rates of nasopharyngitis and oral candidiasis, which were observed in approximately 12% and 8%, respectively, of treated patients during the randomized phase remained at about the same level in the long-term follow up. There were no new safety signals, he said.
 

JNJ-2113 Is First Potential Oral IL-23 Inhibitor

JNJ-2113 is a first-in-class oral peptide that binds to the IL-23 receptor, blocking the IL-23 signaling pathway. If approved, it would be the first oral therapy targeting IL-23. The 16-week outcomes of the dose-finding FRONTIER 1 phase 2b trial were published in The New England Journal of Medicine earlier this year. The primary endpoint was PASI 75, achieved by 79% of those on the 100 mg twice daily dose at week 16, vs 9% on placebo, and at 52 weeks, was 76%. 

“The proportion of patients achieving the FRONTIER 1 primary endpoint was maintained from week 16 to the end of week 52 in the extension study,” Dr. Ferris said, but further pointed out that rates of near or complete clearance achieved at week 16 were also essentially unchanged at week 52. This was true of PASI scores and IGA. 

Clearance of psoriatic lesions on the scalp was particularly impressive. By scalp-specific IGA, rates of clear or near clear (0/1) were not just maintained but improved over the course of follow-up, reaching 75.1% at 52 weeks in the highest dose group, she said.

JNJ-2113 was well tolerated in FRONTIER 1 and remained so during long-term follow-up, in the FRONTIER 2 extension study, according to Dr. Ferris. The most common complaints with JNJ-2113, such as nasopharyngitis (18.1% vs 25.7% in placebo), did not appear to differ significantly from placebo and the treatment remained well tolerated over the course of the extended follow-up.

There are limited direct comparisons of different biologics active in the treatment of plaque psoriasis for efficacy and safety, but these data appear to show a depth and durability of benefit for psoriasis that is exceptional, Dr. Lebwohl told this news organization. “The PASI 100 scores achieved by bimekizumab exceed anything we have seen to date,” he said. “And the durability of those exceedingly high scores is remarkable.”

Dr. Lebwohl reports financial relationships with approximately 40 pharmaceutical companies, including UCB Pharma, which developed bimekizumab. Dr. Ferris reports financial relationships with more than 20 pharmaceutical companies, including Janssen, which is developing JNJ-2113.

TOPLINE:

A study found that 94% of best-selling baby cleansers contain allergens, despite their hypoallergenic claims.

METHODOLOGY:

• Many baby cleansers are marketed as “hypoallergenic,” but these claims are not validated. 
• This study assessed the potential allergens and marketing claims in best-selling baby cleansers. 
• The researchers collected ingredients and marketing claims of the top 50 best-selling baby body wash products sold on Amazon on April 4, 2023. 
• Ingredient lists were checked for potential allergens using the 2020 American Contact Dermatitis Society (ACDS) core allergen series, which lists 90 common allergens for adults and children.

TAKEAWAY:

• In the 50 cleansers tested, 10 allergens were identified. Overall, 94% of the cleansers contained at least one allergen, averaging 2.9 allergens per product; cocamidopropyl betaine  (72%), fragrance (64%), and sodium benzoate (54%) were the most common allergens. 
• All cleansers had at least five marketing claims, with an average of 10.9 claims per product; the most common claims were “paraben-free” (88%), “phthalate-free” (84%), “tear-free” (74%), and “hypoallergenic” or “allergy-tested” (74%). 
• There was no significant difference in the number of allergens in the cleansers marketed as “hypoallergenic” or “allergy tested” compared with cleansers that did not have these claims (P = .843).
• Fewer allergens were found in cleansers endorsed by the National Eczema Association (P = .004) or labeled “synthetic fragrance-free” (P = .003).
• There was a positive correlation between a greater number of allergens and an increased number of marketing claims (r = 0.547, P < .001) and a negative correlation between cost and number of allergens (r = −0.450, P = .001).

IN PRACTICE:

TOPLINE:

A study found that 94% of best-selling baby cleansers contain allergens, despite their hypoallergenic claims.

METHODOLOGY:

• Many baby cleansers are marketed as “hypoallergenic,” but these claims are not validated. 
• This study assessed the potential allergens and marketing claims in best-selling baby cleansers. 
• The researchers collected ingredients and marketing claims of the top 50 best-selling baby body wash products sold on Amazon on April 4, 2023. 
• Ingredient lists were checked for potential allergens using the 2020 American Contact Dermatitis Society (ACDS) core allergen series, which lists 90 common allergens for adults and children.

TAKEAWAY:

• In the 50 cleansers tested, 10 allergens were identified. Overall, 94% of the cleansers contained at least one allergen, averaging 2.9 allergens per product; cocamidopropyl betaine  (72%), fragrance (64%), and sodium benzoate (54%) were the most common allergens. 
• All cleansers had at least five marketing claims, with an average of 10.9 claims per product; the most common claims were “paraben-free” (88%), “phthalate-free” (84%), “tear-free” (74%), and “hypoallergenic” or “allergy-tested” (74%). 
• There was no significant difference in the number of allergens in the cleansers marketed as “hypoallergenic” or “allergy tested” compared with cleansers that did not have these claims (P = .843).
• Fewer allergens were found in cleansers endorsed by the National Eczema Association (P = .004) or labeled “synthetic fragrance-free” (P = .003).
• There was a positive correlation between a greater number of allergens and an increased number of marketing claims (r = 0.547, P < .001) and a negative correlation between cost and number of allergens (r = −0.450, P = .001).

IN PRACTICE:

Because marketing claims like “hypoallergenic” may be misleading, “clinicians should counsel parents to carefully examine cleanser ingredients or consider selecting cleansers” endorsed by the National Eczema Association or another international eczema organization, especially for infants and children with a history of atopic dermatitis, the authors wrote.

SAN DIEGO — In separate studies evaluating treatments for severe forms of alopecia, inhibitors of Janus kinases (JAKs) produced clinically meaningful hair regrowth, according to late-breaking data presented at the annual meeting of  the American Academy of Dermatology.

In one study of brepocitinib, the target was cicatricial alopecia (CA), a form of hair loss for which there are no approved therapies. In the other, a subanalysis from phase 3 trials of ritlecitinib for alopecia areata (AA), hair regrowth was shown in the subset of patients who entered the study with alopecia totalis or alopecia universalis (AT/AU).

Reflecting comments from several experts, including one of the late-breaking session moderators, April W. Armstrong, MD, MPH, professor and chief of dermatology, University of California, Los Angeles, said that the CA study, which matched clinical response to changes in CA biomarkers, suggested that the results are a potential breakthrough.

“This is the first placebo-controlled study with an oral JAK inhibitor that not only shows that scarring alopecia can be reversible but also gives insights to the mechanism of action and which patients might respond best,” Emma Guttman-Yassky, MD, PhD, said in an interview. Dr. Guttman-Yassky, professor of Dermatology and Immunology, and director of the Laboratory of Inflammatory Skin Diseases, Icahn School of Medicine at Mount Sinai, New York City, was the study’s senior investigator.

Scarring Alopecia and Brepocitinib

For the study of scarring alopecia, 49 patients with CA were randomized in a 3:1 ratio to brepocitinib, a first-in-class inhibitor that targets both JAK1 and TYK2, or placebo. Because of the small size of the study, the primary endpoint was the change in CA biomarkers. The secondary outcome was clinical response, but because of a correlation between the two, these were mutually reinforcing.

Of the subtypes, nine patients enrolled in the study had frontal fibrosing alopecia (FFA), 16 had lichen planopilaris (LPP) alopecia, and 24 had central centrifugal cicatricial alopecia (CCCA). All of the forms of CA are more common in women overall and women of color specifically, particularly CCCA. For this analysis, the FFA and LPP subtypes were considered similar for assessing response and were combined.

The data included a comparison of response and safety during the 24-week randomization phase, as well as an additional follow-up conducted after another 24 weeks of open-label treatment. During the second phase, all patients on placebo were switched to active treatment.

Overall, there was a reduction in all four of the key scalp inflammatory biomarkers measured among those in the combined FFA/LLP group. In the placebo group, each of these markers — interferon gamma (IFN-gamma), CCLS, CXCL10, and STAT1 — increased over the same time period. In almost all cases, the differences were statistically significant.

In the CCCA subgroup, the same pattern (an increase among those on placebo but a decrease among those on brepocitinib) was observed for CCLS and CXCL10. For IFN-gamma and STAT1, a rise was observed among those on placebo and those on active treatment, although the rise was greater for placebo.

For clinical response, improvement on brepocitinib was observed on disease activity indexes, particularly among those in the FFA/LLP group, according to Marguerite Meariman, MD, a dermatology resident at Mount Sinai, who presented the results. She called the improvement in clinical activity scores at 48 weeks “dramatic.” Moreover, improvement was apparent within 4 weeks of starting therapy.

For CCCA, a more challenging condition to treat, Dr. Meariman said that no further progression might represent an acceptable response for many patients, but there were also cases of hair regrowth in this subset. Although improvement was not generally on the order seen among those with FFA/LLP, she suggested that there is promise even in these more difficult patients.

Further studies are planned, but Dr. Meariman said that it might be important to focus on early treatment regardless of CA subtype. She noted that patients with less than 5 years disease duration typically did better than those with longer durations.

Ritlecitinib for AT/AU

The analysis of patients with AT/AU was based on a subset analysis from the ALLEGRO phase 2b/3 study of ritlecitinib, which targets JAK3 and TEC kinases. The full results of the ALLEGRO trial were published last year in The Lancet. In the new late-breaker analysis, Severity of Alopecia Tool (SALT) scores were evaluated on an observed or last-observation-carried-forward basis. Generally, responses in the subgroup of patients with AT/AU, who had a median SALT score of 80.3 (signifying 80.3% hair loss) at baseline, were only modestly lower than those in the overall trial.

At 24 months, about 50% of patients achieved a SALT score of 20, according to Melissa Piliang, MD, chair of Dermatology at the Cleveland Clinic, Cleveland, Ohio, who presented the data. In this group, as in the non-AT/AU population, responses climbed over time, and these responses have been maintained for as long as patients have remained on therapy.

At the more rigorous threshold of SALT < 10, the proportion of responders was only slightly lower, meaning a substantial proportion of patients with AT/AU “are achieving 90% or more of hair regrowth, so really an excellent response,” Dr. Piliang said.

For the subgroup with AU, specifically, regrowth of eyebrows and eyelashes was also observed in a substantial proportion, according to Dr. Piliang. Attributed to the often-devastating psychological burden of hair loss, patient-reported assessments of these responses global were generally “even better” than those reported by the investigators.

However, Dr. Piliang advised clinicians to treat AA as early as possible. Despite the benefits seen in the AT/AU subgroup, she pointed out that starting treatment before total hair loss is associated with a higher likelihood of complete or nearly complete hair regrowth.

There are no data from the ALLEGRO trial to determine how long hair regrowth persists after discontinuation of ritlecitinib, which has been approved for the treatment of AA, but Dr. Piliang said that patients should be told that lifelong therapy should be expected in the vast majority of individuals, whether or not AA has advanced to AT/AU.

“In my experience with JAK inhibitors, you lose response when you come off these drugs,” she said.

Dr. Meariman reported a financial relationship with AbbVie. Dr. Piliang reported financial relationships with Eli Lilly, Pfizer, and Proctor & Gamble. Dr. Armstrong reported financial relationships with more than 30 pharmaceutical companies, including those that manufacture JAK inhibitors. Dr. Guttman-Yassky reported financial relationships with more than 30 companies, including those that manufacture JAK inhibitors.

Hand, foot, and mouth disease (HFMD) is a viral infection that commonly affects children under the age of five. It is primarily caused by coxsackieviruses and other enterovirus species.¹ While it predominantly affects children, it is important to note that it can also affect adults. Although it is not a life threatening infection, it can cause a painful rash and is highly contagious. The infection is easily spread in multiple ways, including via respiratory droplets, contact with vesicular or nasal secretions, or through fecal-oral transmission. Most cases occur during the summer and fall seasons but individuals can be infected at any time of the year.

HFMD typically starts with a few days of non-specific viral symptoms, such as fever, cough, sore throat, and fatigue. It is then followed by an eruption of intraoral macules and vesicles and a widespread distribution of oval shaped macules that predominantly involve the hands and feet.¹ Both children and adults can present atypically. Atypical presentations include vesicles and bullae on extensor surfaces such as the forearms, as well as eruptions on the face or buttocks.² Other atypical morphologies include eczema herpeticum-like, Gianotti-Crosti-like, and purpuric/petechiae.³ Atypical hand, food, and mouth disease cases are often caused by coxsackievirus A6, however other strains of coxsackievirus can also cause atypical symptoms.^2,3

Our 35-year-old female patient presented with eroded papules and vesicles around the mouth. A diagnosis of atypical HFMD was made clinically in the following days when the patient developed the more classic intraoral and acral macules and vesicles.

• While half of all vitiligo cases manifest within the initial two decades of life, no guidelines specifically address the management of vitiligo in children, adolescents, and young adults with vitiligo.
• A protocol was established to formulate consensus recommendations addressing questions related to pediatric vitiligo.
• Overall, 50 articles on topical corticosteroids and/or topical calcineurin inhibitors, five on topical Janus kinase inhibitors, and two each on pseudocatalase and microdermabrasion were included.
• The participants recorded their agreement levels with the formulated statements, using a 5-point Likert scale.

TAKEAWAY:

• TCIs, TCSs, JAK inhibitors, and phototherapy, specifically narrowband ultraviolet (UV)-B light therapy, are mainstay treatments; the combination of UV-B light and topical therapy may enhance initial repigmentation.
• Long-term monitoring for skin cancers is advised, and short outdoor UV exposure is suggested for pediatric patients.
• TCIs, such as tacrolimus and pimecrolimus, are recommended as first-line therapy, particularly on the face, applied twice daily for ≥ 3 months; continued use for 6-12 additional months is recommended if repigmentation is observed.
• The choice of TCS class depends on the site and planned usage duration. Short-term use or overlap with TCIs is recommended because of the risk for atrophy with long-term TCS use. Class 5-6 agents are another option.
• For areas with thin skin, TCSs can be considered second-line treatments.
• Topical JAK inhibitors, specifically topical 1.5% ruxolitinib cream, are recommended for patients aged ≥ 12 years, as first- or second-line therapy. Limitation to 10% body surface area is recommended to minimize systemic absorption. Limited evidence exists for children aged < 12 years.

IN PRACTICE:

“Effective therapy requires a focus on long-term therapeutic interventions to maximize the local gain and retention of pigmentation with a trial period of twice-weekly application. Counseling should include discussion of the chronicity of vitiligo and the need for long-term care,” the authors wrote.

LIMITATIONS:

Some of the recommendations were opinion-based because of the scarcity of evidence-based literature.

The consensus statement was published on March 13 in JAMA Dermatology.

Sublingual immunotherapy (SLIT) is as safe and effective for high-risk older children and adolescents as oral immunotherapy (OIT) is for infants and preschoolers, according to new research.

Preliminary data from a study of more than 180 pediatric patients with multiple food allergies showed that while most patients had mild symptoms, none experienced a severe grade 4 reaction during the buildup and maintenance phase of SLIT.

In addition, 70% of those tested at the end of the treatment protocol were able to tolerate 300 mg of their allergen, a success rate nearly as high as that for OIT.

The study was published in The Journal of Allergy and Clinical Immunology: In Practice.

SLIT has been used successfully in the treatment of environmental allergens such as grass and tree pollen and dust mites. In this study, researchers decided to test SLIT’s effectiveness and safety in the treatment of food allergies in older children.

“We knew that OIT is very effective and safe in infants and toddlers, but there was literature illustrating that for older, school-age kids and adolescents, OIT is not safe enough, as those older age groups tend to have higher risk of severe reaction during treatment,” senior author Edmond Chan, MD, clinical professor of allergy at the University of British Columbia and pediatric allergist at BC Children’s Hospital, both in Vancouver, British Columbia, Canada, told this news organization. “With that knowledge, we decided to explore SLIT as another first-phase therapy for the older kids.”

The investigators recruited 188 high-risk older children aged 4-18 years for multifood SLIT. Most (61.7%) participants had multiple food allergies. Approximately 68% were male, and the population’s median age was 11.3 years.

Nearly half (48.4%) of participants had atopic dermatitis, 45.2% had asthma, 58.0% had allergic rhinitis, and 2.66% had preexisting eosinophilic esophagitis.

Most (75.0%) of the children were classified as higher risk, and 23 had a history of a grade 3 or 4 reaction before beginning SLIT.

Of the 188 children who were initially enrolled in the study, 173 (92.0%) finished their SLIT buildup phase.

Because the study started when COVID-19 pandemic restrictions were in place, the SLIT protocol mandated that patients be seen virtually. The patients’ caregivers learned how to mix and administer the required doses at home using recipes specially developed by the research team that used products bought at the grocery store.

A wide variety of food allergens were treated, including peanut, other legumes, tree nuts, sesame, other seeds, egg, cow’s milk, fish, wheat, shrimp, and other allergens.

The children built up to 2-mg protein SLIT maintenance over the course of three to five visits under nurse supervision.

After 1-2 years of daily SLIT maintenance, patients were offered a low-dose oral food challenge (OFC; cumulative dose: 300 mg of protein) with the goal of bypassing OIT buildup.

Nearly all patients (93.1%) had symptoms during SLIT buildup, but most were mild grade 1 (52.1%) or 2 (40.4%) reactions. Only one patient had a grade 3 reaction. None of the patients experienced a severe grade 4 reaction.

The most common grade 1 reaction was oral itch, an expected symptom of SLIT, which occurred in 82.7% of the patients.

Four patients (2.10%) received epinephrine during buildup and went to the emergency department. All these patients returned to continue SLIT without further need for epinephrine.

To test the effectiveness of SLIT, the researchers performed 50 low-dose OFCs in 20 patients. Of these food challenges, 35 (70%) were successful, and patients were asked to start daily 300-mg OIT maintenance, thus bypassing OIT buildup.

An additional nine OFCs that were unsuccessful were counseled to self-escalate from 80 mg or higher to 300 mg at home with medical guidance as needed.

“Our preliminary data of 20 patients and 50 low-dose oral food challenges suggest that an initial phase of 1-2 years of 2-mg daily SLIT therapy may be a safe and effective way to bypass the OIT buildup phase without the need for dozens of in-person visits with an allergist,” said Dr. Chan.

“So now we have the best of both worlds. We harness the safety of SLIT for the first 1-2 years, with the effectiveness of OIT for the remainder of the treatment period,” he said.
 

Adds to Evidence

Commenting on the study for this news organization, Julia Upton, MD, associate professor of pediatrics at the University of Toronto, Toronto, Ontario, Canada, said, “This study adds to the evidence that consistent, low exposure to food drives meaningful desensitization far above the daily dose.” Upton did not participate in the research.

“Prior prospective studies in SLIT demonstrated that small single-digit-milligram doses and time greatly increased the threshold of reaction. This real-world report suggests that a way to utilize that threshold increase is by switching to a commonly used maintenance dose of OIT,” said Dr. Upton.

“Although few patients have been assessed for the 300-mg challenge, this study is notable for the age group of 4-18 years, and that many of the patients had reacted to low doses in the past. It also shows that many families are capable of diluting and mixing their own immunotherapy solutions with store-bought foods under the guidance of an experienced allergy clinic,” she added.

“Overall, evidence is building that by various routes, initial small amounts with minimal updoses, plus the tincture of time, may be preferred to multiple frequent updosing from multiple perspectives, including safety, feasibility, cost, and medical resources. It will also be important to understand the preferences and goals of the patient and family as various regimens become more available,” Dr. Upton concluded.

The study was funded by BC Children’s Hospital Foundation. Dr. Chan reported receiving research support from DVB Technologies; has been a member of advisory boards for Pfizer, Miravo, Medexus, Leo Pharma, Kaleo, DBV, AllerGenis, Sanofi, Genzyme, Bausch Health, Avir Pharma, AstraZeneca, ALK, and Alladapt; and was a colead of the CSACI OIT guidelines. Dr. Upton reported research support/grants from Novartis, Regeneron, Sanofi, ALK Abello, DBV Technologies, CIHR, and SickKids Food Allergy and Anaphylaxis Program and fees from Pfizer, ALK Abello, Bausch Health, Astra Zeneca, and Pharming.

SAN DIEGO — Just weeks after the American Academy of Dermatology (AAD) published its updated acne management guidelines, a dermatologist who helped write the recommendations provided colleagues with insight into recently approved topical therapies, the importance of multimodal therapy, and a controversial report linking benzoyl peroxide (BP) to the carcinogen benzene.

In regard to topical treatments, the guidelines make a “strong” recommendation for topical retinoids based on “moderate” evidence, Andrea L. Zaenglein, MD, professor of dermatology and pediatrics, Penn State University, Hershey, Pennsylvania, said at the annual meeting of the American Academy of Dermatology. The recommendation was based on a pooled analysis of four randomized controlled trials that found patients with acne who used the medications were more likely to have improvement via the Investigator Global Assessment (IGA) scale at 12 weeks than were those treated with a vehicle (risk ratio [RR], 1.57; 1.21-2.04).

The updated guidelines were published on January 30 in the Journal of the American Academy of Dermatology. The previous guidelines were issued in 2016.

“We have four current retinoids that we use: adapalene, tretinoin, tazarotene, and trifarotene,” Dr. Zaenglein said. “Typically, when we think about retinoids, we think of adapalene as being more tolerable and tazarotene as being more effective. But we also know that they can work to prevent and treat scarring, and they work against comedonal lesions and inflammatory lesions.”

Newer concentrations include tretinoin 0.05% lotion, tazarotene 0.045% lotion, and trifarotene 0.005% cream. She noted that this trifarotene concentration can be helpful for moderate truncal acne and also referred to evidence that whey protein appears to exacerbate that condition. “I always ask teenage kids about that: Are they using those protein powders?”
 

Recommendations for ‘Multimodal Therapy,’ Especially With Antibiotics

Dr. Zaenglein highlighted a “good practice statement” in the new guidelines that says, “when managing acne with topical medications, we recommend multimodal therapy combining multiple mechanisms of action.”

Topical antibiotics are effective treatments on their own and include erythromycin, clindamycin, and minocycline (Minocin), she said. But the guidelines, which refer to evidence supporting them as “moderate,” do not recommend them as monotherapy because of the risk for antibiotic resistance.

The oral retinoid isotretinoin may be appropriate in conjunction with topical medications, she said, “and we also recommend fixed combination products because they’re associated with increased adherence.”

Dermatologists are familiar with several of these products because “we’ve been using them for years and years,” she said. The guidelines note that “compared to vehicle at 12 weeks, a greater proportion of patients treated with combined BP and topical retinoid achieved IGA success in three RCTs (RR, 2.19; 1.77-2.72).”

Dr. Zaenglein noted that the guidelines recommend that patients taking antibiotics also use benzoyl peroxide, which has “moderate” evidence regarding preventing the development of antibiotic resistance. “Lower strengths tend to be less irritating, and over-the-counter formulations are readily available,” she said, adding that colleagues should make sure to warn patients about the risk of bleaching clothes and towels with BP.

Now, there’s a newly approved treatment, the first fixed-dose triple combination therapy for acne, she said. It combines 1.2% clindamycin, 3.1% benzoyl peroxide, and 0.15% adapalene (Cabtreo) and is Food and Drug Administration (FDA)-approved for treating acne in patients ages 12 and up.

The new AAD guidelines note that “potential adverse effect profiles of the fixed-dose combinations generally reflect those of the individual agents in summation. Some fixed-dose combination products may be less expensive than prescribing their individual components separately.” The evidence supporting fixed-dose combinations in conjunction with benzoyl peroxide is considered “moderate.”

Dapsone gel, 7.5% (Aczone) is another option for acne. “It’s a topical so you don’t need to do G6PD [glucose-6-phosphate dehydrogenase] testing,” Dr. Zaenglein said. “It’s well tolerated, and mean total lesions fell by 48.9% vs 43.2% for vehicle,” in a 2018 study, which she said also found that females benefited more than males from this treatment.

Clascoterone 1% cream (Winlevi), approved in 2020, is appropriate for males and females aged 12 and up, Dr. Zaenglein said. She noted that it’s the only topical anti-androgen that can be used in males. However, while it has a “high” level of evidence because of phase 3 clinical trials showing benefits in moderate to severe acne, the AAD guidelines only conditionally recommend this option because the high price of clascoterone “may impact equitable acne treatment access.” The price listed on the website GoodRx (accessed on March 12) lists drugstore prices for a single 60-gram tube as ranging from $590 to $671.

“One of the harder things is trying to figure out where clascoterone fits in our kind of standard combination therapy,” she said. “Much like other hormonal therapies, it works better over the long term.”

Two more topical options per the AAD guidelines are salicylic acid, based on one randomized controlled trial, and azelaic acid (Azelex, Finacea), based on three randomized controlled trials. Both of these recommendations are conditional because of limited evidence: Evidence is considered “low” for salicylic acid and “moderate” for azelaic acid, the guidelines say, and azelaic acid “may be particularly helpful for patients with sensitive skin or darker skin types due to its lightening effect on dyspigmentation.”

As for risk for topical treatments during pregnancy/lactation, the guidelines note that topical therapies other than topical retinoids are “preferred” during pregnancy. Tazarotene is contraindicated during pregnancy, and salicylic acid should be used only in limited areas of exposure. There are no data for dapsone and clascoterone during pregnancy/lactation, and minocycline is “not recommended.”

The guideline authors noted that “available evidence is insufficient to develop a recommendation on the use of topical glycolic acid, sulfur, sodium sulfacetamide, and resorcinol for acne treatment or to make recommendations that compare topical BP, retinoids, antibiotics, and their combinations directly against each other.”
 

Could BP Post a Risk From Benzene?

Dr. Zaenglein highlighted a recently released report by Valisure, an independent laboratory, which reported finding high levels of the cancer-causing chemical benzene in several acne treatments, including brands such as Clearasil. “They didn’t release all of the ones that they evaluated, but there were a lot ... that we commonly recommend for our patients,” she said.

On March 6, CBS News reported that Valisure “ran tests at various temperatures over 18 days and found some products ‘can form over 800 times the conditionally restricted FDA concentration limit of two parts per million (ppm) for benzene’ in 2 weeks at 50° C (122° F),” but that benzene levels “at room temperature were more modest, ranging from about one to 24 parts per million.”

Dr. Zaenglein said she’s not ready to urge patients to discontinue BP, although in light of the findings, “I will tell them to store it at room temperature or lower.”

For now, it’s important to wait for independent verification of the results, she said. “And then it’s up to the manufacturers to reevaluate the stability of their benzoyl peroxide products with heat.”

Dr. Zaenglein disclosed relationships with AbbVie, Arcutis, Biofrontera, Galderma, and Incyte (grants/research funding), Church & Dwight (consulting fees), and UCB (consulting honoraria).

SAN DIEGO — Just weeks after the American Academy of Dermatology (AAD) published its updated acne management guidelines, a dermatologist who helped write the recommendations provided colleagues with insight into recently approved topical therapies, the importance of multimodal therapy, and a controversial report linking benzoyl peroxide (BP) to the carcinogen benzene.

In regard to topical treatments, the guidelines make a “strong” recommendation for topical retinoids based on “moderate” evidence, Andrea L. Zaenglein, MD, professor of dermatology and pediatrics, Penn State University, Hershey, Pennsylvania, said at the annual meeting of the American Academy of Dermatology. The recommendation was based on a pooled analysis of four randomized controlled trials that found patients with acne who used the medications were more likely to have improvement via the Investigator Global Assessment (IGA) scale at 12 weeks than were those treated with a vehicle (risk ratio [RR], 1.57; 1.21-2.04).

The updated guidelines were published on January 30 in the Journal of the American Academy of Dermatology. The previous guidelines were issued in 2016.

“We have four current retinoids that we use: adapalene, tretinoin, tazarotene, and trifarotene,” Dr. Zaenglein said. “Typically, when we think about retinoids, we think of adapalene as being more tolerable and tazarotene as being more effective. But we also know that they can work to prevent and treat scarring, and they work against comedonal lesions and inflammatory lesions.”

Newer concentrations include tretinoin 0.05% lotion, tazarotene 0.045% lotion, and trifarotene 0.005% cream. She noted that this trifarotene concentration can be helpful for moderate truncal acne and also referred to evidence that whey protein appears to exacerbate that condition. “I always ask teenage kids about that: Are they using those protein powders?”
 

Recommendations for ‘Multimodal Therapy,’ Especially With Antibiotics

Dr. Zaenglein highlighted a “good practice statement” in the new guidelines that says, “when managing acne with topical medications, we recommend multimodal therapy combining multiple mechanisms of action.”

Topical antibiotics are effective treatments on their own and include erythromycin, clindamycin, and minocycline (Minocin), she said. But the guidelines, which refer to evidence supporting them as “moderate,” do not recommend them as monotherapy because of the risk for antibiotic resistance.

The oral retinoid isotretinoin may be appropriate in conjunction with topical medications, she said, “and we also recommend fixed combination products because they’re associated with increased adherence.”

Dermatologists are familiar with several of these products because “we’ve been using them for years and years,” she said. The guidelines note that “compared to vehicle at 12 weeks, a greater proportion of patients treated with combined BP and topical retinoid achieved IGA success in three RCTs (RR, 2.19; 1.77-2.72).”

Dr. Zaenglein noted that the guidelines recommend that patients taking antibiotics also use benzoyl peroxide, which has “moderate” evidence regarding preventing the development of antibiotic resistance. “Lower strengths tend to be less irritating, and over-the-counter formulations are readily available,” she said, adding that colleagues should make sure to warn patients about the risk of bleaching clothes and towels with BP.

Now, there’s a newly approved treatment, the first fixed-dose triple combination therapy for acne, she said. It combines 1.2% clindamycin, 3.1% benzoyl peroxide, and 0.15% adapalene (Cabtreo) and is Food and Drug Administration (FDA)-approved for treating acne in patients ages 12 and up.

The new AAD guidelines note that “potential adverse effect profiles of the fixed-dose combinations generally reflect those of the individual agents in summation. Some fixed-dose combination products may be less expensive than prescribing their individual components separately.” The evidence supporting fixed-dose combinations in conjunction with benzoyl peroxide is considered “moderate.”

Dapsone gel, 7.5% (Aczone) is another option for acne. “It’s a topical so you don’t need to do G6PD [glucose-6-phosphate dehydrogenase] testing,” Dr. Zaenglein said. “It’s well tolerated, and mean total lesions fell by 48.9% vs 43.2% for vehicle,” in a 2018 study, which she said also found that females benefited more than males from this treatment.

Clascoterone 1% cream (Winlevi), approved in 2020, is appropriate for males and females aged 12 and up, Dr. Zaenglein said. She noted that it’s the only topical anti-androgen that can be used in males. However, while it has a “high” level of evidence because of phase 3 clinical trials showing benefits in moderate to severe acne, the AAD guidelines only conditionally recommend this option because the high price of clascoterone “may impact equitable acne treatment access.” The price listed on the website GoodRx (accessed on March 12) lists drugstore prices for a single 60-gram tube as ranging from $590 to $671.

“One of the harder things is trying to figure out where clascoterone fits in our kind of standard combination therapy,” she said. “Much like other hormonal therapies, it works better over the long term.”

Two more topical options per the AAD guidelines are salicylic acid, based on one randomized controlled trial, and azelaic acid (Azelex, Finacea), based on three randomized controlled trials. Both of these recommendations are conditional because of limited evidence: Evidence is considered “low” for salicylic acid and “moderate” for azelaic acid, the guidelines say, and azelaic acid “may be particularly helpful for patients with sensitive skin or darker skin types due to its lightening effect on dyspigmentation.”

As for risk for topical treatments during pregnancy/lactation, the guidelines note that topical therapies other than topical retinoids are “preferred” during pregnancy. Tazarotene is contraindicated during pregnancy, and salicylic acid should be used only in limited areas of exposure. There are no data for dapsone and clascoterone during pregnancy/lactation, and minocycline is “not recommended.”

The guideline authors noted that “available evidence is insufficient to develop a recommendation on the use of topical glycolic acid, sulfur, sodium sulfacetamide, and resorcinol for acne treatment or to make recommendations that compare topical BP, retinoids, antibiotics, and their combinations directly against each other.”
