In a striking convergence of veterinary biology and medical science, researchers from the University of Sheffield (England) have unveiled findings that could potentially advance the treatment of diabetic foot ulcers, a condition affecting an estimated 18.6 million people worldwide. The unexpected ingredient in this potentially transformative therapy? Feces from endangered species, sourced from Yorkshire Wildlife Park, Doncaster, England.

The scourge of antibiotic resistance

Diabetic foot ulcers are a significant challenge in health care, not only because of their prevalence but also because of the alarming rise of antibiotic-resistant bacterial infections. Current antibiotic treatments frequently fail, leading to life-altering consequences like amputations and significant health care costs – estimated at one-third of the total direct costs of diabetes care. The critical need for alternative therapies has propelled scientists into a pressing search for novel antimicrobial agents.

A pioneering approach: zoo poo as bioactive goldmine

Led by Professor Graham Stafford, chair of molecular microbiology at the University of Sheffield, the research team began to explore a rather unorthodox resource: the fecal matter of endangered animals like Guinea baboons, lemurs, and Visayan pigs. While such a source might seem surprising at first glance, the rationale becomes clear when considering the nature of bacteriophages.

What are bacteriophages?

Bacteriophages, commonly known as phages, are viruses that selectively target and kill bacteria. Despite being the most prevalent biological entities on Earth, their therapeutic potential has remained largely untapped. What makes bacteriophages particularly interesting is their ability to kill antibiotic-resistant bacteria – a feature making them prime candidates for treating otherwise unmanageable diabetic foot ulcers. (Armstrong DG, et al; Fish R, et al).

Findings and future directions

Professor Stafford and his team discovered that the feces of several endangered animals harbored bacteriophages capable of killing bacterial strains resistant to antibiotics. The findings not only hold promise for a groundbreaking treatment but also provide another compelling reason to conserve endangered species: Their inherent biodiversity might contain cures for a range of infectious diseases.

While research is ongoing and clinical trials have not yet begun, the preliminary results are overwhelmingly promising. Phages isolated from the feces could potentially be incorporated into dressings for ulcers, creating a novel treatment modality that is both effective and cost-saving.

We often look to complex technologies and synthetic materials for medical science breakthroughs, yet sometimes the most innovative solutions can be found in the most overlooked places. In this case, the feces of endangered species could turn out to be a vital asset in battling antibiotic resistance, thus affecting diabetic foot care in ways we never imagined possible.

The research conducted at the University of Sheffield also serves as a powerful argument for a One Health approach – a multidisciplinary field focusing on the interconnectedness of human, animal, and environmental health.

This intriguing work reaffirms the need for an interdisciplinary approach in tackling the world’s pressing health care challenges. The collaborative efforts between the University of Sheffield and Yorkshire Wildlife Park exemplify how academic research and conservation can come together to yield solutions for some of the most devastating and costly health conditions, while also underscoring the invaluable role that biodiversity plays in our collective well-being. Here’s to teaming up to act against amputation worldwide.

The Food and Drug Administration has issued a complete response letter regarding lebrikizumab, an investigational biologic for the treatment of adult and adolescent patients with moderate to severe atopic dermatitis, describing concerns about findings made during an inspection of a third-party contract manufacturer that included the “monoclonal antibody drug substance” for lebrikizumab, Eli Lilly announced in an Oct. 2 press release.

Lebrikizumab is under FDA review for treating atopic dermatitis; a complete response letter indicates that the review has been completed, and highlights issues that need to be addressed before a final decision on approval is made.

The press release noted that the agency did not raise any concerns about the clinical data package, safety, or label for lebrikizumab, an investigational, monoclonal antibody that binds to the cytokine interleukin (IL)-13, and is designed to be administered once per month.

In the press release, the company said it would work with the third-party manufacturer and the FDA to address the feedback “in order to make lebrikizumab available to patients.”

The risk for inflammatory bowel disease (IBD) was increased among children and adults with atopic dermatitis (AD), with the risk increasing with AD severity, according to data from a large cohort study published recently in JAMA Dermatology.

The study also found an increased risk for Crohn’s disease (CD) in adults and children with AD, as well as an increased risk for ulcerative colitis (UC) in adults with AD and in children with severe AD, researchers reported.

“It is imperative for clinicians to understand atopic dermatitis and the trajectory of our patients with it in order to provide the best standard of care,” senior author Joel M. Gelfand, MD, MSCE, professor in clinical investigation with the department of dermatology at the University of Pennsylvania, Philadelphia, said in a news release.

“There are new and better treatments for AD today, and there will likely continue to be more,” continued Dr. Gelfand. “But providers have to understand how those treatments could impact other autoimmune diseases. For patients with AD and another autoimmune disease, some currently available medications can exacerbate symptoms of their other disease or can help treat two immune diseases at the same time.”

The study results support the idea that AD and IBD may have some common underlying causes, said Sheilagh Maguiness, MD, pediatric dermatologist and associate professor in the department of dermatology at the University of Minnesota, Minneapolis, who was asked to comment on the findings.

“As the pathogenesis of AD is becoming better understood, we are recognizing that, rather than simply a cutaneous disease, the underlying inflammation and immune dysregulation that leads to AD best categorizes it as a systemic inflammatory disease with significant comorbidities,” she told this news organization. “I will be more likely to ask patients and families about GI symptoms, and if positive, may plan to refer to GI more readily than in the past,” added Dr. Maguiness, who was not involved in the study.

UK general practice cohort

AD has been associated with an increasing number of comorbidities, including IBD, but studies linking AD with IBD, including UC, have had mixed results, the authors wrote. And few studies have separately examined how AD or AD severity may be linked with UC or CD risk.

To examine the risk for new-onset IBD, UC, and CD in children and adults with atopic dermatitis, the researchers conducted a population-based cohort study using the THIN (The Health Improvement Network) electronic medical record database of patients registered with United Kingdom general practices. They used 21 years of data collected from January 1994 to February 2015.

The researchers matched each patient who had AD with up to five controls based on age, practice, and index date. Because THIN does not capture AD severity, they used treatment exposure assessed by dermatologic referrals and treatments patients received as proxy for severity. The authors used logistic regression to examine the risks for IBD, UC, and CD in children (aged 1-10) with AD, and in adults (aged 30-68) with AD, and they compared their outcomes with the outcomes for controls.

In the pediatric cohort, the team compared 409,431 children who had AD with 1.8 million children without AD. Slightly more than half were boys. In the adult cohort, they compared 625,083 people who had AD with 2.68 million controls, and slightly more than half were women. Data on race or ethnicity were not available, the authors wrote, but the THIN database is considered to be representative of the UK population.
 

AD severity linked with IBD risk

The risk for new-onset inflammatory bowel disease appears to be higher in children and adults with AD, and the risk varies based on age, AD severity, and subtype of inflammatory bowel disease, the authors reported.

Overall, AD in children was associated with a 44% increased risk for IBD (adjusted hazard ratio (HR), 1.44; 95% confidence interval [CI], 1.31-1.58) compared with controls, the authors reported. They found a 74% increased risk for CD in children with AD compared with controls (HR, 1.74; 95% CI, 1.54-1.97). More severe AD was linked with increased risk for both IBD and CD.

AD did not appear to increase risk for UC in children, except those with severe AD (HR, 1.65; 95% CI, 1.02-2.67).

Overall, adults with AD had a 34% (HR, 1.34; 95% CI, 1.27-1.40) increased risk for IBD, a 36% (HR, 1.36; 95% CI, 1.26-1.47) increased risk for CD, and a 32% (HR, 1.32; 95% CI, 1.24-1.41) increased risk for UC, with risk increasing with increased AD severity.

Robust data with cautionary note

“This study provides the most robust data to date on the association between IBD and AD. It provides clear evidence for an association that most dermatologists or primary care providers are not typically taught in training,” Kelly Scarberry, MD, assistant professor of dermatology at Case Western Reserve University in Cleveland, told this news organization. “I will be much more likely to pursue diagnostic workup in my AD patients who have GI complaints.”

Case Western Reserve University

However, AD severity was measured by proxy, added Dr. Scarberry, who was not involved in the study, and the study lacked important racial and ethnic data.

Lindsay C. Strowd, MD, associate professor of dermatology at Wake Forest University, Winston-Salem, N.C., also not involved in the study, said in an interview that she found the size of the cohort and the longitudinal data to be strengths of the study.

Wake Forest University

But, she added, the “lack of family IBD history, race and ethnicity, and comorbidities, are limitations, as is treatment exposure used as a proxy for disease severity, given that physician treatment practices differ.”

For Steven R. Feldman, MD, PhD, professor of dermatology at Wake Forest, “the most important conclusion, and it is a definitive finding, [is] that IBD is uncommon, even in patients with AD.

“The findings could be misinterpreted,” cautioned Dr. Feldman, who was not involved in the study. “While there is an increased relative risk, the absolute risk is small.” The study found that “the highest relative risk group is children with severe AD, who have a roughly fivefold increased risk for CD.” However, he added, the incidence rates of CD were 0.68 per 1,000 person-years in children with severe AD and 0.08 per 1,000 person-years in controls.

“Basically, because Crohn’s disease and IBD don’t happen very often, the modest increase in relative risk the investigators found doesn’t amount to much we’d have to worry about,” he said. “The findings do not show any need to screen patients with atopic dermatitis for IBD any more than we’d need to screen patients without atopic dermatitis.”

The increased relative risk “could be a clue to possible genetic connections between diseases,” he added. “But when we’re making clinical decisions, those decisions should be based on the absolute risk that some event may occur.”

Susan Massick, MD, dermatologist and associate professor at The Ohio State University in Columbus, who was not involved with the study, said in an interview, “We are still scratching the surface of the complexity of the immune and inflammatory pathways in AD and IBD.

The Ohio State Wexner Medical Center

“It is important to remember that correlation does not mean causation,” Dr. Massick said. “It would be premature to draw direct conclusions based on this study alone.”

The authors recommend future related studies in more diverse populations.

Dr. Gelfand and two coauthors reported ties with Pfizer, which supported the study. Dr. Gelfand and three coauthors reported ties with other pharmaceutical companies. Dr. Maguiness, Dr. Scarberry, Dr. Strowd, and Dr. Massick reported having no relevant disclosures. Dr. Feldman reported ties with Pfizer and other pharmaceutical companies.

“The findings could be misinterpreted,” cautioned Dr. Feldman, who was not involved in the study. “While there is an increased relative risk, the absolute risk is small.” The study found that “the highest relative risk group is children with severe AD, who have a roughly fivefold increased risk for CD.” However, he added, the incidence rates of CD were 0.68 per 1,000 person-years in children with severe AD and 0.08 per 1,000 person-years in controls.

“Basically, because Crohn’s disease and IBD don’t happen very often, the modest increase in relative risk the investigators found doesn’t amount to much we’d have to worry about,” he said. “The findings do not show any need to screen patients with atopic dermatitis for IBD any more than we’d need to screen patients without atopic dermatitis.”

The increased relative risk “could be a clue to possible genetic connections between diseases,” he added. “But when we’re making clinical decisions, those decisions should be based on the absolute risk that some event may occur.”

Susan Massick, MD, dermatologist and associate professor at The Ohio State University in Columbus, who was not involved with the study, said in an interview, “We are still scratching the surface of the complexity of the immune and inflammatory pathways in AD and IBD.

“It is important to remember that correlation does not mean causation,” Dr. Massick said. “It would be premature to draw direct conclusions based on this study alone.”

The authors recommend future related studies in more diverse populations.

Dr. Gelfand and two coauthors reported ties with Pfizer, which supported the study. Dr. Gelfand and three coauthors reported ties with other pharmaceutical companies. Dr. Maguiness, Dr. Scarberry, Dr. Strowd, and Dr. Massick reported having no relevant disclosures. Dr. Feldman reported ties with Pfizer and other pharmaceutical companies.

TOPLINE:

Cutaneous immune-related adverse events are associated with improved overall and progression-free survival among patients treated with immune checkpoint inhibitors (ICIs).

METHODOLOGY:

• Emerging evidence suggests that the presence of cutaneous immune-related adverse events may be linked with favorable outcomes among patients with cancer who receive ICIs.
• Researchers conducted a systematic review and meta-analysis that included 23 studies and a total of 22,749 patients with cancer who received ICI treatment; studies compared outcomes among patients with and those without cutaneous immune-related adverse events.
• The major outcomes evaluated in the analysis were overall survival and progression-free survival (PFS); subgroup analyses assessed cutaneous immune-related adverse event type, cancer type, and other factors.

TAKEAWAY:

• The occurrence of cutaneous immune-related adverse events was associated with improved PFS (hazard ratio, 0.52; P < .001) and overall survival (HR, 0.61; P < .001).
• In the subgroup analysis, patients with eczematous (HR, 0.69), lichenoid or lichen planus–like skin lesions (HR, 0.51), pruritus without rash (HR, 0.70), psoriasis (HR, 0.63), or vitiligo (HR, 0.30) demonstrated a significant overall survival advantage. Vitiligo was the only adverse event associated with a PFS advantage (HR, 0.28).
• Among patients with melanoma, analyses revealed a significant association between the incidence of cutaneous immune-related adverse events and improved overall survival (HR, 0.51) and PFS (HR, 0.45). The authors highlighted similar findings among patients with non–small cell lung cancer (HR, 0.50 for overall survival and 0.61 for PFS).

IN PRACTICE:

“These data suggest that [cutaneous immune-related adverse events] may have useful prognostic value in ICI treatment,” the authors concluded.

SOURCE:

The analysis, led by Fei Wang, MD, Zhong Da Hospital, School of Medicine, Southeast University, Nanjing, China, was published online in JAMA Dermatology.

LIMITATIONS:

Most of the data came from retrospective studies, and there were limited data on specific patient subgroups. The Egger tests, used to assess potential publication bias in meta-analyses, revealed publication bias.

DISCLOSURES:

No disclosures were reported. The study was supported by a grant from the Postgraduate Research and Practice Innovation Program of Jiangsu Province.

TOPLINE:

The number of primary melanomas is not an independent risk factor for mortality.

METHODOLOGY:

• The difference in outcomes between people with multiple primary melanomas (MPMs) and a single primary melanoma (SPM) has not been established.
• To compare 10-year melanoma-specific mortality and overall mortality between people with MPMs and SPM, researchers drew from the Melanoma Patterns of Care study, a population-based observational analysis of residents in the state of New South Wales, Australia, who had a melanoma reported to the state cancer registry over 12 months in 2006-2007, and were followed up until 2018, for a median of almost 12 years.
• The researchers performed logistic regression analyses to assess 10-year melanoma-specific mortality differences between the two groups.

TAKEAWAY:

• Of 3,404 people included in the analysis, 2,830 had an SPM and 574 developed MPMs during follow-up.
• On multivariable regression adjusted for pathologic characteristics of the thickest lesion in the MPM group, no significant differences were seen in 10-year melanoma-specific mortality between the two groups (odds ratio, 0.85; 95% confidence interval, 0.58-1.24; P = .40).
• Sensitivity analyses adjusted for parameters of the first primary melanoma among patients with MPMs revealed similar findings (OR, 1.34; 95% CI, 0.92-1.96; P = .12).
• On multivariable analysis using data from the thickest lesion, factors independently associated with melanoma-specific mortality were male sex, disadvantaged socioeconomic status (based on location of residence), and Breslow thickness.
• Factors independently associated with 10-year overall mortality were like those seen in other studies and included sex, Breslow thickness, ulceration status, and socioeconomic disadvantage.

IN PRACTICE:

“The results of our study suggest that the number of primary melanomas is not an independent risk factor for mortality,” the researchers concluded. “In addition, the detection of melanoma at an early stage (with a thin Breslow thickness) rather than an intrinsic biologic factor remains the biggest influence on melanoma mortality after diagnosis of one or more melanomas.”

SOURCE:

Corresponding author Serigne N. Lo, PhD, of the Melanoma Institute Australia, led the research. The study was published in the Journal of the American Academy of Dermatology.

LIMITATIONS:

No adjustments for treatment modality were made in the study, and at baseline survey, effective systemic treatments for melanoma were not available.

DISCLOSURES:

This study was supported by the Australian National Health and Medical Research Council, Cancer Institute New South Wales, and the New South Wale State Government via a grant to the New South Wales Melanoma Network. Additional support was provided by Melanoma Institute Australia and the New South Wales Melanoma Network.

TOPLINE:

Hidradenitis suppurativa (HS) experts collaborated to reach consensus on a core set of outcome measures, with the intent of improving the management of HS in clinical practice.

METHODOLOGY:

• Participants in the study were 55 HS experts from the HiSTORIC group (dermatologists, internists, surgeons, and nurses) and 24 patient research partners.
• The group identified clinician- and patient-reported HS outcome measures in the literature, then participated in an online item reduction survey, followed by an electronic Delphi survey to reach consensus on which measures should be used in clinical practice. Consensus was defined as at least 67% of participants agreeing/strongly agreeing or disagreeing/strongly disagreeing about the use of a measure in clinical practice.
• The initial literature search yielded 11 HS studies with clinician-reported outcome measures and 12 with patient-reported outcomes; of these, eight and five, respectively, were included in the final reduction survey.

TAKEAWAY:

• The group reached consensus on two HS outcome measures for use in clinical practice: the HS Investigator Global Assessment (HS-IGA) score, a clinician-reported outcome measure selected by the HS experts, and the HS Quality of Life (HiSQOL) score, a patient-reported outcome measure selected by the patient research partners.
• The HS-IGA score uses a number between 0 and 5 based on the sum of abscesses, inflammatory and noninflammatory nodules, and tunnels in regions of the upper or lower body.
• The HiSQOL, a disease-specific quality-of-life measure for adults with HS, is designed to capture unique features of HS, including symptoms (such as pain, itch, odor, and drainage) and psychosocial outcomes and activities that may be affected by the disease.

IN PRACTICE:

“The intent of these recommendations is to provide an objective framework with both clinician and patient input that can facilitate bidirectional discussion, trust building, and decision making on the current treatment strategy and the need to adjust or escalate treatment in an appropriate time frame,” the authors wrote.

SOURCE:

The study was published online in JAMA Dermatology. The lead author was Nicole Mastacouris, MS, and the corresponding author was Amit Garg, MD, both of Northwell Health, New Hyde Park, N.Y.

LIMITATIONS:

The consensus results may have been affected by variations in HS management by region. Neither measure has been studied in clinical practice, and practice variability may limit their implementation.

DISCLOSURES:

The study was supported by grants from UCB and AbbVie. Ms. Mastacouris had no financial disclosures. Dr. Garg disclosed grant support from AbbVie and UCB during the conduct of the study, as well as personal fees from AbbVie, UCB, Aclaris Therapeutics, Anaptys Bio, Aristea Therapeutics, Boehringer Ingelheim, Bristol-Myers Squibb, Incyte, Insmed, Janssen, Novartis, Pfizer, Sonoma Biotherapeutics, Union Therapeutics, Ventyx Biosciences, and Viela Biosciences during the conduct of the study; Dr. Garg also holds patents for HS-IGA and HiSQOL. Many other coauthors disclosed relationships with multiple companies, including AbbVie and UCB, and some also disclosed patents, including patents for HiSQOL and HS Area and Severity Index.

TOPLINE:

Nearly three-quarters of adults with alopecia areata (AA) were not receiving treatment 1 year after diagnosis, according to a retrospective cohort study using data from more than 45,000 individuals.

METHODOLOGY:

• The study population included 45,483 adults aged 18 years and older with new diagnoses of AA between Oct. 15, 2015, and Feb. 28, 2020. Data were from a large U.S. health care database that included medical and pharmacy claims.
• The mean age of the participants was 43.8 years, and 65.7% were female.
• The researchers measured variables that might relate to AA and its treatment patterns within 1 year of starting the study and during the first year of the study, with data collected at 1, 42, 84, and 365 days after study entry.

TAKEAWAYS:

• During the first year after diagnosis, 66.4% of patients received at least one treatment for AA at one or more time points.
• At 1 year, 71.8% of patients were not receiving any active treatment for AA.
• Among those who received treatment, intralesional injections were the most often prescribed therapy (41.8% of patients), followed by topical corticosteroids (40.9%), intramuscular corticosteroids (38.1%), and oral corticosteroids (20.6%).
• Patients diagnosed with either alopecia totalis or alopecia universalis were significantly less likely to receive intralesional steroids and significantly more likely to receive topical corticosteroids than those without these diagnoses (11.1% vs. 44.1% and 25.4% vs. 42.1, respectively).

IN PRACTICE:

The results highlight the need to determine why so many alopecia patients with AA were no longer on treatment after 1 year, although treatment trends may change with the emergence of new therapies, such as JAK inhibitors and others, according to the authors.

SOURCE:

The lead author of the study was Hemin Lee, MD, MPH, Brigham and Women’s Hospital, Boston. The study was published online in JAMA Dermatology.

LIMITATIONS:

The use of insurance claims data did not allow analysis of over-the-counter medications and treatments, and the lack of a single ICD-10 code for defining AA could have resulted in misclassification of outcomes.

DISCLOSURES:

The study received no outside funding, and Dr. Lee had no disclosures. One author had disclosures that included receiving personal fees from Pfizer and Concert outside of the submitted study and participating in alopecia-related trials with Lilly, Concert, Aclaris, and Incyte. Another author’s disclosures included receiving personal fees from companies that included Pfizer, Concert, Lilly, and AbbVie. No other disclosures were reported.

The results highlight the need to determine why so many alopecia patients with AA were no longer on treatment after 1 year, although treatment trends may change with the emergence of new therapies, such as JAK inhibitors and others, according to the authors.

SOURCE:

The lead author of the study was Hemin Lee, MD, MPH, Brigham and Women’s Hospital, Boston. The study was published online in JAMA Dermatology.

LIMITATIONS:

The use of insurance claims data did not allow analysis of over-the-counter medications and treatments, and the lack of a single ICD-10 code for defining AA could have resulted in misclassification of outcomes.

DISCLOSURES:

The study received no outside funding, and Dr. Lee had no disclosures. One author had disclosures that included receiving personal fees from Pfizer and Concert outside of the submitted study and participating in alopecia-related trials with Lilly, Concert, Aclaris, and Incyte. Another author’s disclosures included receiving personal fees from companies that included Pfizer, Concert, Lilly, and AbbVie. No other disclosures were reported.

This patient had a posttraumatic tache noir (also known as talon noir on the volar aspect of the feet); it is a subcorneal hematoma. The diagnosis is made clinically. Dermoscopic evaluation of tache/talon noir will reveal “pebbles on a ridge” or “satellite globules.” Confirmation of tache/talon noir can be made by paring the corneum with a #15 blade, which will reveal blood in the shavings and punctate lesions.¹

This patient noted that the knob of his baseball bat rubbed the hypothenar eminence of his nondominant hand when he took a swing. The sheer force of the knob led to the subcorneal hematoma. Tache noir was high on the differential due to his physician’s clinical experience with similar cases. Tache noir occurs predominantly in people ages 12 to 24 years, without regard to gender.² The condition is commonly found in athletes who participate in baseball, cricket, racquet sports, weightlifting, and rock climbing.^2-4

Talon noir occurs most commonly in athletes who are frequently jumping, turning, and pivoting, as in football, basketball, tennis, and lacrosse.

Tache noir can be differentiated from other conditions by the presence of preserved architecture of the skin surface and punctate capillaries beneath the stratum corneum. The differential diagnosis includes verruca vulgaris, acral melanoma, and a traumatic tattoo.

Talon/tache noir are benign conditions that do not require treatment and do not affect sports performance. The lesion will usually self-resolve within a matter of weeks from onset or can even be gently scraped with a sterile needle or blade.

This patient was advised that the lesion would resolve on its own. His knee pain was determined to be a simple case of patellofemoral syndrome or “runner’s knee” and he opted to complete a home exercise program to obtain relief.

The European Commission has authorized the marketing of ritlecitinib to treat adults and adolescents 12 years of age and older with severe alopecia areata. This makes ritlecitinib the first medicine authorized by the EC to treat individuals with severe alopecia areata as young as 12 years of age.

Taken as a once-daily pill, ritlecitinib is a dual inhibitor of the TEC family of tyrosine kinases and of Janus kinase 3. In June of 2023, the drug received FDA approval for the treatment of severe alopecia areata in people ages 12 and older in the United States.

According to a press release from Pfizer, which developed the drug, EC approval was based on the pivotal ALLEGRO clinical trial program, which included the ALLEGRO phase 2b/3 study that evaluated ritlecitinib in patients aged 12 years and older with alopecia areata with 50% or more scalp hair loss, including patients with alopecia totalis (total scalp hair loss) and alopecia universalis (total body hair loss). Results from this study showed that 13.4% of adults and adolescents achieved 90% or more scalp hair coverage (Severity of Alopecia Tool score of 10 or less) after 24 weeks of treatment with ritlecitinib 50 mg, compared with 1.5% of those on placebo.

The study also measured Patient Global Impression of Change (PGI-C). At week 24, 49.2% of participants treated with ritlecitinib reported a PGI-C response of “moderate” to “great” improvement in their alopecia areata, compared with 9.2% with placebo.

According to results from an ongoing, long-term phase 3 study of ritlecitinib known as ALLEGRO-LT, the most common adverse reactions reported from use of the drug included diarrhea (9.2%), acne (6.2%), upper respiratory tract infections (6.2%), urticaria (4.6%), rash (3.8%), folliculitis (3.1%), and dizziness (2.3%), the company press release said.

SAN DIEGO – Injecting a scar with intralesional steroids is a popular way to reduce its size and soften the surrounding tissue, but proper technique matters, according to Victor Ross, MD.

“A lot of lip service is paid to how to inject the steroid,” Dr. Ross, director of laser and cosmetic dermatology at the Scripps Clinic in San Diego, said at the annual Masters of Aesthetics Symposium. “The most important part is the amount and the fastidiousness that you have injecting. You should see the tip of the needle and be very slow. Use a 1 cc syringe.” He used to inject scars with triamcinolone acetate 40 mg/mL, but now he almost always injects 10-20 mg/mL to avoid inducing white streak-like atrophy or hypopigmentation around the treated area.

“When you treat a scar, you treat the features of the scar that make it stand out,” Dr. Ross continued. “If it’s red, you address the hyperemia. If it’s brown, you address the pigment. You want to have a reasonable pathophysiological basis for what you’re doing. Understand how the scar got there and have a reasonable algorithm.” When he counsels patients about clinical outcomes to expect, he emphasizes rehabilitation instead of blemish-free perfection. “It’s not making the scar go away,” he said. “It’s not restoring completely normal skin form and function; it’s a restorative effort to get toward normality. That’s what it’s all about.”

Besides injecting scars with triamcinolone acetate, other scar treatment options include intralesional 5-fluorouracil, oral antihistamines, COX-2 inhibitors, hydrogel sheeting, compression, acoustic wave therapy, photodynamic therapy, radiofrequency, and lasers. “I’m not a big fan of low-level light; it probably does something [to scars], but I’m skeptical,” Dr. Ross said.

In his clinical opinion, most scars respond best to treatments with ablative and nonablative fractional lasers tuned to gentle settings such as an energy level of 20 millijoules at a density of 5%-10%. “Every scar deserves a chance for laser remediation and rehabilitation,” he said. “With radiation scars you want to be particularly gentle. If you have a Mohs scar that has been subsequently treated with radiation, I would lower my settings by half, because I’ve had some scars worsen with settings for red scars after radiation therapy.”

He often uses fractional lasers for stubborn acne scarring. “The hyperemic component you can treat with a vascular laser, then come back [and treat the scarring] with a nonablative fractional laser, or you could use radiofrequency microneedling as well,” Dr. Ross said.

New or innovative scar treatments coming down the pike, he said, include the following: mitomycin C (applied topically, he said that this has worked well for postoperative keloids), tamoxifen, oral methotrexate, imiquimod (which has mixed results to date), platelet-rich plasma, and retinoids.

Dr. Ross disclosed having research and financial ties to numerous pharmaceutical and device companies.
