Isolated nail psoriasis may bring arthritis into play
for dermatologists to improve their diagnostic accuracy,” investigators said in a research letter.
Diagnosis of isolated NP was delayed by almost 3 years among the 87 cases recorded and “arthritis was most often diagnosed concurrently with NP,” at a major nail referral center between Jan. 1, 2001, and Dec. 21, 2022, Michelle J. Chang of Drexel University, Philadelphia, and associates reported.
In what the authors say is, “the largest study documenting clinical and histologic features in patients with isolated NP,” the two most common clinical features were onycholysis and nail plate pitting, seen in 79% and 70% of cases, respectively. No other single feature had a prevalence higher than 28%.
The most frequent clinical dyad was onycholysis and pitting in 66% of patients, followed by onycholysis/nail thickening in 33% and onycholysis/splinter hemorrhage in 32%. The most common histologic features were parakeratosis in 79% and neutrophil infiltration in 48%, the investigators said.
Psoriatic arthritis (PsA), a focus of the study, occurred in 10 (11%) of the 87 individuals with isolated NP. Considering this finding, and “the close proximity between the nail apparatus and joint, we hypothesize a reciprocal relationship, with nail unit inflammation precipitating PsA,” Ms. Chang and associates wrote.

Topical or intralesional cidofovir an option for recalcitrant warts
HONOLULU – Combining or those located in areas that are challenging to treat, according to John S. Barbieri, MD, MBA.
“There are 5 million office visits per year in the United States for warts and molluscum, and they’re most common in pediatrics,” Dr. Barbieri, of the department of dermatology at Brigham and Women’s Hospital, Boston, said at the Hawaii Dermatology Seminar provided by MedscapeLIVE! “In fact, some studies have suggested that one in three children in primary school suffers from warts.”
According to a 2012 Cochrane review of topical therapies for warts, first-line treatments such as salicylic acid, cryotherapy, 5-FU, or Candida antigen injection often have modest efficacy when used alone. For example, the authors found that salicylic acid and cryotherapy cleared warts in about 60%-70% of cases, respectively, but clearance rates were improved by combining the two therapies.
In an earlier literature review and meta-analysis, investigators evaluated the effect of 5-FU plus salicylic acid or salicylic acid alone. The therapeutic effect for common warts across all studies was a 63.4% response rate (complete healing) for 5-FU/SA vversus 23.1% for the 5-FU–free controls, respectively. For plantar warts, the response rate was 63% versus 11%, respectively.
“But what about the person with multiple warts or those in challenging locations where you might worry about destructive treatments hurting the nail fold or causing nail dystrophy?” Dr. Barbieri asked. “Maybe they’ve used salicylic acid or intralesional Candida and they’re still not getting better. What can we do for these patients?”
Emerging research suggests that topical cidofovir can be a valuable option for recalcitrant warts or those in sensitive locations. In a case report of a 10-year-old boy with more than 50 severe verrucous papules on his hands and face that were recalcitrant to multiple conventional therapies, topical 1% cidofovir applied daily for 8 weeks was effective, with no adverse side effects. A young female patient who presented to Dr. Barbieri with multiple warts around the nail matrix of several fingers experienced complete clearance after treatment with topical cidofovir, he said. Other researchers found this approach to be effective for plantar warts as well, in a report of two brothers with severe combined immunodeficiency after hematopoietic stem cell transplantation with persistent warts that did not respond to traditional topical treatments.
“Topical cidofovir is typically a painless treatment, which is nice, especially for our pediatric patients who might be afraid of other therapies like or cryotherapy or intralesional injections,” One limitation is that it is “a bit expensive,” Dr. Barbieri said. “To have topical cidofovir compounded is typically $100-$300, depending on the quantity and strength that you ask for.”
Intralesional cidofovir is another treatment option. In a retrospective study of 58 patients, Dr. Barbieri and colleagues evaluated the outcome of intralesional cidofovir treatment of warts in immunocompromised and nonimmunocompromised patients. Rates of improvement ranged from 98.3% to 100%, while resolution rates ranged from 75.9% to 97.6%.
“Most of the patients had warts for more than 5 years and almost half of them had recalcitrant warts,” Dr. Barbieri said. “These were mostly adult patients, but I think this is a treatment that can work in younger populations as well. About 10%-15% had HIV or cancer or diabetes or were transplant recipients, but despite these challenges and despite these recalcitrant warts, about 100% had improvement.”
He pointed out that cidofovir is available as a 75 mg/mL vial that comes with a 5 mL single-use vial. He dilutes this with normal saline to create a 15 mg/mL solution.
“If you want to be efficient you can try to schedule multiple patients together on the same day as a single vial is sufficient to treat about 25 patients,” assuming about 1 mL is injected per patient, he said. “The challenge with intralesional cidofovir is that it’s painful beyond just the needle part of the injection. Sometimes a nerve block can be helpful. But this can be an effective treatment for patients with recalcitrant warts or those with comorbidities.”
Other intralesional therapies to try for recalcitrant warts, he said, include bleomycin (1 U/mL solution, 1-2 mL per treatment, spaced every 2-4 weeks), and 5-FU (a 4:1 mixture of 5-FU [50 mg/mL] and 2% lidocaine).

Treating nail psoriasis: Intralesional injections and biologics
HONOLULU – combined with systemic therapy.
One might think of intralesional injections “as a torture method from the medieval days,” she said at the Hawaii Dermatology Seminar provided by MedscapeLIVE!, but intramatricial corticosteroid injections have been performed for many years as a treatment for nail psoriasis, typically with triamcinolone acetonide.
According to Dr. Armstrong, professor of dermatology and associate dean of clinical research at the University of Southern California, Los Angeles, nail matrix psoriasis can present as pitting, leukonychia, red macules in the lunula, crumbling, or trachyonychia. Nail bed psoriasis can present as splinter hemorrhages and onycholysis, hyperkeratosis and splinter hemorrhages, salmon patch or oil spot dyschromia, or onycholysis and salmon patch dyschromia.
In a German cross-sectional study of patients with psoriasis, nails were one of the body sites that have the greatest impact on quality of life – especially those in younger age groups.
While topical treatments are generally considered first for limited disease involving special areas such as the nails, systemic therapy is warranted in patients with moderate-to-severe involvement of specific sites or in those refractory to topical therapy, Dr. Armstrong said.
In 2018, Indian researchers published results from an open-label study of 17 patients, with nail psoriasis, comparing three treatments . Patients were assigned to three groups of 30 nails each and treated with intramatricial injections of triamcinolone acetonide (10 mg/mL), methotrexate (25 mg/mL), and cyclosporine (50 mg/mL), respectively. Each nail was treated with two injections at 6-week intervals and graded at 24 weeks using the Nail Psoriasis Severity Index (NAPSI). In the triamcinolone acetonide and methotrexate groups, 50% of treated nails showed a greater than 75% improvement at 24 weeks, compared with 33% of those in the cyclosporine group. The most side effects occurred in the nails treated with cyclosporine.
When Dr. Armstrong performs intramatricial injections, she uses triamcinolone acetonide at 10 mg/mL. However, she said, “my favorite way of treating severe nail psoriasis is with biologics.”
In an early study of patients with moderate to severe psoriasis treated with the tumor necrosis factor blocker adalimumab 80 mg subcutaneously at week 0, followed by 40 mg subcutaneously every other week from weeks 1 to 15, a post hoc analysis on the effects on nail psoriasis showed a 10-point decrease in the median NAPSI score through week 16 – from 21 to 11 .
In VOYAGE 2, which compared the interleukin-23 blocker guselkumab and adalimumab in patients with moderate to severe psoriasis, the mean percent improvement from baseline in the NAPSI score was similar in patients treated with adalimumab or guselkumab at week 16 (39.6% vs. 46.9%, respectively) and at week 24 (55% vs. 53.7%).
In another study of patients with nail psoriasis, researchers evaluated the efficacy of the IL-17A antagonist secukinumab 150 mg, 300 mg, or placebo at weeks 0, 1, 2, 3, and 4, and every 4 weeks thereafter for 2.5 years. At 2.5 years, the mean reduction in NAPSI score was 63.6% in the secukinumab 150 mg group and 73.3% in the secukinumab 300 mg group.
“I do have to tell my patients what to expect, because the nails grow out slowly, but over time we do see this increase in efficacy,” Dr. Armstrong said.
Studies of another IL-17A antagonist, ixekizumab, have yielded positive results as well, she noted. In 2021, Taiwanese researchers published a systematic review and network meta-analysis to evaluate the efficacy of small molecule inhibitors and biologics in treating nail psoriasis. They drew from 39 studies involving 15,673 patients with nail psoriasis and found that the oral Janus kinase inhibitor tofacitinib and ixekizumab had the best efficacy for treating nail psoriasis in 10-16 weeks and 24-26 weeks, respectively.
“They found that overall, the biologics have a good effect on nail psoriasis and that the treatment effects are overall quite similar,” Dr. Armstrong said.
Dr. Armstrong disclosed that she is a consultant or adviser for numerous pharmaceutical companies. She has also received research funding from Bristol-Myers Squibb, Dermavant, Dermira, Leo, Lilly, Pfizer, and UCB Pharma.

AT THE MEDSCAPELIVE! HAWAII DERMATOLOGY SEMINAR
Treatment of several nail disorders reviewed
ORLANDO – at the ODAC Dermatology, Aesthetic, & Surgical Conference.
Dr. Hinshaw, professor of dermatology at the University of Wisconsin, Madison, reviewed several disorders and provided guidance on diagnosis, and achieving the best outcomes for patients.
Retronychia: This is an ingrowth of the proximal nail plate into the proximal nail fold, which mimics chronic paronychia, or nail inflammation. A key to the diagnosis is elevation of the proximal nail plate, Dr. Hinshaw said, along with yellowing of the nail. In some cases, a second or even third nail can be seen growing under the nail plate, she said.
“There has been traumatic lifting of the central portion of the nail plate over the matrix,” she explained. “The body thinks it needs to make a new nail plate, so it starts to do that while the primary nail plate has not yet let go.”
Sometimes, treatment with topical steroids will be effective, she said, but there might be secondary changes that require further treatment. She referred to a systematic review and a suggested treatment algorithm for retronychia, published in 2022, which can be helpful. “Even though this entity is not very well studied, there are at least some consensus approaches that the proximal nail plate needs to be removed, if not the entire nail plate,” she said.
Onycholysis: Essential to treatment of this disorder – separation of the nail from the nail bed – is knowing when it is secondary to another issue, whether it is a fungal infection, psoriasis, or tumor under the nail.
When a patient has primary onycholysis “and there’s nothing else going on in the nail, remember to try retinoids,” Dr. Hinshaw said. She suggested clipping back the nail and treating the nail bed every night with tretinoin 0.025%. If the nail bed becomes irritated, patients can pause treatment for a few days, she said.
If onycholysis has been present for 6-12 months, it can become permanent. But she said she has had success treating patients who’ve had it for a year or even a little longer, “so what we don’t want to do is give up hope for patients.”
Pyogenic granuloma (PG) in the nail: These are benign vascular tumors that can mimic more serious conditions, Dr. Hinshaw said. In adults, PG requires a histologic diagnosis, she said.
“So these all really should have a biopsy,” because of potential confusion with amelanotic melanoma or squamous cell carcinoma, she said, although in children, a biopsy is likely not necessary.
Treatment with topical beta-blockers can be effective for PG, she said, and avoids the scarring seen with surgical removal. “These are benign conditions – we want them to go away, but we want these patients to have a functional nail thereafter.”
Periungual or subungual warts: For these warts, which are alongside or under the nail, destructive approaches can cause scarring of the nail bed and are far from optimal, she said.
“We’d like to avoid that, of course.” Therefore, treatments such as lasers and liquid nitrogen “would be much further down, if at all, on my list,” she said.
Injections of the antiviral cidofovir, into the dermis right under the wart, can be highly effective, and one or two treatments is often enough, Dr. Hinshaw said. Sometimes, local anesthesia isn’t even needed for the injection, she said. “This is a wonderful option,” she added.

ORLANDO – at the ODAC Dermatology, Aesthetic, & Surgical Conference.
Dr. Hinshaw, professor of dermatology at the University of Wisconsin, Madison, reviewed several disorders and provided guidance on diagnosis, and achieving the best outcomes for patients.
Retronychia: This is an ingrowth of the proximal nail plate into the proximal nail fold, which mimics chronic paronychia, or nail inflammation. A key to the diagnosis is elevation of the proximal nail plate, Dr. Hinshaw said, along with yellowing of the nail. In some cases, a second or even third nail can be seen growing under the nail plate, she said.
“There has been traumatic lifting of the central portion of the nail plate over the matrix,” she explained. “The body thinks it needs to make a new nail plate, so it starts to do that while the primary nail plate has not yet let go.”
Sometimes, treatment with topical steroids will be effective, she said, but there might be secondary changes that require further treatment. She referred to a systematic review and a suggested treatment algorithm for retronychia, published in 2022, which can be helpful. “Even though this entity is not very well studied, there are at least some consensus approaches that the proximal nail plate needs to be removed, if not the entire nail plate,” she said.
Onycholysis: Essential to treatment of this disorder – separation of the nail from the nail bed – is knowing when it is secondary to another issue, whether it is a fungal infection, psoriasis, or tumor under the nail.
When a patient has primary onycholysis “and there’s nothing else going on in the nail, remember to try retinoids,” Dr. Hinshaw said. She suggested clipping back the nail and treating the nail bed every night with tretinoin 0.025%. If the nail bed becomes irritated, patients can pause treatment for a few days, she said.

A toddler presents with a dark line on a fingernail
Given the over 1-year history of an unchanging longitudinal band of pigment without extension to the proximal or lateral nailfolds or any other nail findings, the most likely diagnosis is benign longitudinal melanonychia.
Longitudinal melanonychia, also known as melanonychia striata, describes a brown to black streak of pigment extending from the nail matrix to the free edge of the nail.1,2
This disorder can occur secondary to a wide variety of benign and pathologic causes including lentigines, nevi, melanoma, chronic trauma, inflammatory skin diseases, systemic diseases, iatrogenic causes, and genetic syndromes.3 In melanocytic causes of longitudinal melanonychia, either melanocytic activation or hyperplasia drive pigmentary development leading to the brown to black band seen in the nail.4 Benign causes of longitudinal melanonychia include benign melanocyte activation, lentigo, and benign nevus.1
What’s the differential diagnosis?
The differential diagnosis for longitudinal melanonychia can include a wide variety of local and systemic causes. For our discussion, we will limit our differential to other locally involved disorders of the nail including subungual melanoma, subungual hematoma, onychomycosis, and glomus tumor.
Subungual melanoma is a rare subtype of acral lentiginous melanoma that most often presents as longitudinal melanonychia. Subungual melanoma is more common in those aged 50-70 years, individuals with personal or family history of melanoma or dysplastic nevus syndrome, and persons with African American, Native American, and Asian descent. Longitudinal melanonychia features that can be concerning for subungual melanoma include the presence of multiple colors, width greater than or equal to 3 mm, blurry borders, rapid increase in size, and extension to the proximal or lateral nailfolds (Hutchinson’s sign). Biopsy is required to make the diagnosis of subungual melanoma but is not necessary for melanonychia without atypical features.
Treatment of subungual melanoma depends on disease stage and can range from wide local excision of the nail apparatus to amputation of the affected digit and management with a medical oncologist. Given the absence of concerning neoplastic findings or personal or family history of melanoma, subungual melanoma is unlikely in this patient.
Subungual hematoma is an accumulation of blood underneath the nail plate that is typically the result of acute or chronic trauma to the distal phalanx. It can present as purple, red, pink, brown, or black discoloration under the nail plate and is most commonly found on the first toe. With acute trauma, pain is usually present upon initial injury. Subungual hematomas typically resolve on their own with normal nail growth. The absence of a history of trauma or pain, and the linear appearance of the lesion in our patient are inconsistent with a subungual hematoma.
Onychomycosis is a fungal infection of the nail caused by dermatophytes, nondermatophytes, or yeasts. It may present with longitudinal melanonychia; however, it more often presents with other nail abnormalities such as nail thickening, yellow discoloration, onycholysis, splitting, subungual hyperkeratosis, and nail plate destruction, which are not present in this patient. Furthermore, onychomycosis is more common in adults than children. Diagnosis is usually made with potassium hydroxide (KOH) preparations, histopathologic examination of nail clippings with a periodic acid-Schiff stain, fungal culture, or PCR.
Glomus tumor is a rare, benign neoplasm originating from cells of the glomus body. It is often found in the subungual region, in addition to other areas rich in glomus bodies such as the fingertips, palms, wrists, and forearms. Subungual glomus tumors present as a red, purple, or blueish lesions under the nail plate. Distal notching or an overlying longitudinal fissure may be present. Subungual glomus tumors are typically associated with pinpoint tenderness, paroxysmal pain, and cold sensitivity, features that are not present in our patient. The history and examination of our patient are much more consistent with benign longitudinal melanonychia.
It appears that melanoma associated with longitudinal melanonychia is very rare in children. According to one review published in 2020, only 12 cases of pediatric subungual melanoma have been reported.5 Recent series have observed longitudinal melanonychia in large sets of children, with findings that demonstrate that the vast majority of longitudinal melanonychia either stops progressing or regresses. These investigations therefore recommend serial observation of longitudinal melanonychia except in rare circumstances.6,7
Given the lack of troubling findings or concerning history, our patient was managed with observation. On follow-up 6 months later, he was found to have no change in his nail pigmentation.

Manicure gone wrong leads to cancer diagnosis
. Now, she and her doctor are spreading the word about her ordeal as a lesson that speed and persistence in seeking treatment are the keys that make her type of cancer – squamous cell carcinoma – completely curable.
“She cut me, and the cut wasn’t just a regular cuticle cut. She cut me deep, and that was one of the first times that happened to me,” Grace Garcia, 50, told TODAY.com, recalling the November 2021 incident.
Ms. Garcia had been getting her nails done regularly for 20 years, she said, but happened to go to a different salon than her usual spot because she couldn’t get an appointment during the busy pre-Thanksgiving season. She doesn’t recall whether the technician opened packaging that signals unused tools.
She put antibiotic ointment on the cut, but it didn’t heal after a few days. Eventually, the skin closed and a darkened bump formed. It was painful. She went to her doctor, who said it was a “callus from writing,” she told TODAY.com. But it was on her ring finger, which didn’t seem connected to writing. Her doctor said to keep an eye on it.
Five months after the cut occurred, she mentioned it during a gynecology appointment and was referred to a dermatologist, who also advised keeping an eye on it. A wart developed. She went back to her primary care physician and then to another dermatologist. The spot was biopsied.
Squamous cell carcinoma is a common type of skin cancer, according to the American Academy of Dermatology. It can have many causes, but the cause in Ms. Garcia’s case was both very common and very rare: human papillomavirus, or HPV. HPV is a virus that infects millions of people every year, but it’s not a typical cause of skin cancer.
“It’s pretty rare for several reasons. Generally speaking, the strains that cause cancer from an HPV standpoint tend to be more sexually transmitted,” dermatologist Teo Soleymani told TODAY.com. “In Grace’s case, she had an injury, which became the portal of entry. So that thick skin that we have on our hands and feet that acts as a natural barrier against infections and things like that was no longer the case, and the virus was able to infect her skin.”
Dr. Soleymani said Ms. Garcia’s persistence to get answers likely saved her from losing a finger.
“Your outcomes are entirely dictated by how early you catch them, and very often they’re completely curable,” he said. “Her persistence – not only was she able to have a great outcome, she probably saved herself from having her finger amputated.”

Do collagen supplements benefit the skin?
SAN DIEGO – When patients ask if collagen supplements can benefit their skin, what should you tell them?
According to Ava Shamban, MD, a dermatologist who practices in Santa Monica, Calif., And in her opinion, more research is needed to establish knowledge of the effects and physiologic mechanism of collagen supplementation.
“Collagen is the most abundant protein in the skin; it is found only in animal flesh like meat and fish that contain connective tissue,” she said at the annual Masters of Aesthetics Symposium. “We produce less collagen as we age. External factors can slow down our collagen production, including smoking, sun exposure, lack of sleep/exercise, and alcohol consumption.”
Though human studies are lacking, some trials have found that collagen supplements may improve skin hydration and elasticity. “Maybe there’s some benefit, but the digestive process breaks collagen down into amino acids, so I don’t buy it,” she said.
At the meeting, Dr. Shamban discussed other topics related to the effect of supplements and nutrition on the skin:
Can Nutrafol reverse permanent hair loss? “It definitely doesn’t do that,” she said. “Can it help regrow hair? Perhaps.” Nutrafol is an over-the-counter supplement that aims to relieve moderate hair thinning or strengthen hair to prevent breakage, and is physician-formulated with medical-grade ingredients that target root causes of thinning such as stress, lifestyle, hormones, and nutrition.
As for biotin, “we now know that high levels of biotin can actually cause hair loss,” she said. “If you have advanced hair loss, supplements may not work for you. There is no hair regrowth supplement that can bring back a dead hair follicle. Can it help a miniaturized hair follicle? Maybe. Platelet-rich plasma injections have been shown to stimulate hair growth, but only if the follicle is miniaturized, not if it’s totally gone.”
How does the human microbiome affect skin? In a review of sequencing surveys of healthy adults, “the composition of microbial communities was found to be primarily dependent on the physiology of the skin site, with changes in the relative abundance of bacterial taxa associated with moist, dry, and sebaceous environments,” the authors reported . “The microbiome is the genetic material of all the microbes that live inside the body, including bacteria, fungi, protozoa, and viruses,” Dr. Shamban said. “The more diverse the microbiota is, the healthier it’s considered. That diversity is enriched through a diet full of various vegetables and fruits.”
Nearly all adults are colonized with Cutibacterium acnes (formerly Propionibacterium acnes), but only a minority have acne, which highlights the importance of studying diseases in the broader context of host genetics, immune or barrier defects, the microbiome, and the environment, she added. For example, the decreased diversity of the skin microbiome in people with atopic dermatitis has been linked to a reduction in environmental biodiversity in the areas surrounding their homes.
Do adaptogens have a role in skin care? Adaptogens such as ashwagandha, elderberry, ginseng, licorice root, neem, moringa, and reishi mushrooms have been used in Chinese and Ayurvedic medicine for centuries and are purported to promote adaptability, resilience, and survival of living organisms in stress. They appear to affect the neuroendocrine immune system and at low doses may function as mild stress mimetics.
“The idea is that combining adaptogens into skin care can reinforce and support the skin’s resistance against stressors that can accelerate visible signs of aging,” said Dr. Shamban. “They share some similarities with antioxidants in that their main purpose is to protect the body from external stressors such as UV rays, oxidation, and pollution.” More studies should be conducted to verify effectiveness, she said, “but Eastern practices that have incorporated it for centuries shouldn’t be fully dismissed. Most doctors believe adaptogens are safe, but how they interact with the mechanics of the body’s stress response system remains a mystery.”
Embrace the consumption of micronutrients. Inspired by work from dermatologist Zoe Diana Draelos, MD, Dr. Shamban advises patients to eat a “rainbow of different colored foods” every day, especially those rich in vitamins A, C, and E. Green foods are generally rich in vitamin E, brown foods are rich in trace minerals, and blue/purple foods are rich in antioxidants. “It’s always best to get nutrients from a rich, healthy diet, but sometimes our skin requires extra help,” she said.
A randomized, placebo-controlled, double-blind study by French researchers, which showed that skin is prone to seasonal changes during the winter, particularly in exposed areas, also looked at whether a daily micronutrient supplement with ingredients that included green tea extract, blackcurrant seed oil, and magnesium, had an impact on the negative effects of winter weather on the skin. “The data indicate that oral micronutrient supplementation can be a safe treatment, with no serious side effects, and may prevent or even eliminate the negative effects of winter on the skin,” she said.
Dr. Shamban disclosed that she conducts clinical trials for many pharmaceutical and device companies.
SAN DIEGO – When patients ask if collagen supplements can benefit their skin, what should you tell them?
According to Ava Shamban, MD, a dermatologist who practices in Santa Monica, Calif., And in her opinion, more research is needed to establish knowledge of the effects and physiologic mechanism of collagen supplementation.
“Collagen is the most abundant protein in the skin; it is found only in animal flesh like meat and fish that contain connective tissue,” she said at the annual Masters of Aesthetics Symposium. “We produce less collagen as we age. External factors can slow down our collagen production, including smoking, sun exposure, lack of sleep/exercise, and alcohol consumption.”
Though human studies are lacking, some trials have found that collagen supplements may improve skin hydration and elasticity. “Maybe there’s some benefit, but the digestive process breaks collagen down into amino acids, so I don’t buy it,” she said.
At the meeting, Dr. Shamban discussed other topics related to the effect of supplements and nutrition on the skin:

Alopecia Areata in Skin of Color Patients: New Considerations Sparked by the Approval of Baricitinib
With the introduction of the first US Food and Drug Administration (FDA)–approved medication for alopecia areata (AA)—the Janus kinase (JAK) inhibitor, baricitinib—there is an important focus on this disease in the literature and for practicing dermatologists. Known by all as an autoimmune genetic disease that causes relapsing and remitting nonscarring hair loss, AA is a condition where the psychological burden has been less widely recognized. Patients with AA have reported lower health-related quality of life scores compared to patients with other skin conditions, including psoriasis or atopic dermatitis. In addition, a lesser amount of scalp coverage is negatively correlated to health-related quality of life scores.1 Patients with AA also have a 39% lifetime prevalence of major depressive disorder and generalized anxiety disorder.2 The treatment of AA has been a hodgepodge of topical, intralesional, and systemic agents, all with indirect immunosuppressive or anagen prolongation effects. Now that there is an approved therapy for AA with more treatments likely to be approved in the near future, there must be a focus on real-world outcomes. With the dawn of a new era in the treatment of AA as well as new information showcasing an altered prevalence of AA in skin of color, highlighting disparities among this population may help ease challenges dermatologic providers will face.
Efficacy of Baricitinib in Different Races and Ethnicities
How will patients of different races and ethnicities respond to this new treatment, and how will their emotional health be affected? The 2 phase 3 pivotal trials showing efficacy of baricitinib in AA included Black and Latino patients but not in a way that is representative of the US population.3 Until recently, the most commonly used prevalence of AA in the United States was from the NHANES I study completed between 1971 and 1974, which was between 0.1% and 0.2%4 with minimal focus on race and ethnicity. Recent studies suggest that there may be increased prevalence of this condition in Black patients in the United States. These new findings raise concern around access to care and treatment and the need to tailor psychosocial interventions for populations that may not currently have these supports.
A large cross-sectional study published in 2020 demonstrated that these data remained similar, with a lifetime prevalence of 0.21%.5 Of the 45,016 participants—representative of the US population based on the 2015 US Census—the average age of AA patients was 41.2 years, with 61.3% being White and not of Hispanic origin.5 In recent years, other studies have challenged the narrative that AA predominantly affects White patients.6-8 A different cross-sectional study utilizing National Alopecia Areata Registry data from 2002 to 2016 suggested that Black patients have greater odds of developing AA.6 In this study of 2645 cases of AA, the odds ratios of developing the condition were 1.36 for Blacks, 0.53 for Asians, and 0.83 for Hispanics compared with the referent White population. These results were consistent through the varying subtypes of AA.6 In a reply to these findings, Gonzalez and Fleischer7 analyzed data from the 2007 to 2016 National Ambulatory Medical Care Survey database with a focus on racial and ethnic prevalence of AA. This study concluded that Latino and non-White individuals had an increased likelihood of clinician visits for AA compared with White individuals.7
More evidence of the Black predominance of AA was demonstrated in a study published in 2018. In this large-scale study, 63,960 women from the Nurses’ Health Study (NHS) and 88,368 women from the Nurses’ Health Study II (NHSII) were included to examine prevalence of disease among these US women.8 Analysis showed increased odds of AA based on self-reported race in Black and Hispanic women. Lifetime incidence of AA was greater in Black women, with 2.63 and 5.23 in NHS and NHSII, respectively. It was hypothesized that hairstyling practices in Black and Hispanic women may cause AA to be more noticeable,8 which may drive patients to seek medical evaluation.
Feaster and McMichael9 published information on the epidemiology of AA in a busy hair loss clinic. This retrospective single-institution study of 265 pediatric and adult Black patients with AA seen over a 5-year period showed that patients aged 18 to 34 years were most likely to present for care, which accounted for 35.8% of the study population, followed by patients aged 10 to 17 years, which accounted for 15.1%. This study also found that females were the larger segment of AA patients, with an increased distribution of disease in young patients. Most of these patients (68.2%) had patchy hair loss, and the ophiasis pattern was seen in 15.1%.9 Although the pathogenesis of AA is linked to autoimmunity,10 the leading cause for these epidemiologic findings of increased prevalence in Black patients is still uncertain.
Baricitinib for AA
In June 2022, the FDA announced the first biologic drug approved for the treatment of AA—baricitinib. Baricitinib is an oral, selective, reversible inhibitor of JAK1 and JAK2.3 The phase 3 trials for baricitinib—BRAVE-AA1 (N=654) and BRAVE-AA2 (N=546)—were conducted between March 2019 and May 2020. In these double-blind, parallel-group, randomized, placebo-controlled trials, 33% of the patient population receiving baricitinib accomplished 80% or more scalp coverage at 36 weeks. The Severity of Alopecia Tool (SALT) score also decreased to 20 or less in 36 weeks. The BRAVE-AA1 and BRAVE-AA2 trials consisted of a total of 1200 patients, with only 98 identifying as Black. Of these 98 patients, 33 were randomly selected to receive placebo.3 With studies now suggesting that Black individuals have greater odds of AA compared with White individuals6 and Black patients being more likely to seek medical care for AA,7 the BRAVE-AA1 and BRAVE-AA2 study population did not allow for significant comparative data for Black patients. These studies did not document Latino patient involvement.3 Future studies in AA must recruit a diversified group of study participants to better reflect the patients with an increased likelihood of presenting with AA.
Other Treatments on the Horizon
Baricitinib likely will remain alone in its class for only a short time. Phase 3 trials have been completed for ritlecitinib, brepocitinib, and deuruxolitinib for AA. Ritlecitinib, an irreversible inhibitor of JAK3 and the tyrosine kinase expressed in hepatocellular carcinoma (TEC) kinase family, has met all end points in a phase 2b/3 study.11 Brepocitinib is an oral tyrosine kinase 2/JAK1 inhibitor,12 and deuruxolitinib is an investigational JAK1/2 inhibitor for AA.13
Insurance Coverage Considerations and Health Care Disparities
Prior authorizations have been the initial step for many drugs in varying fields of medical practice. A study completed in 2016 suggested that insurance coverage for biologics used in the treatment of psoriasis was becoming increasingly difficult.14 Prior authorization requirement rates increased from 16% of patients in 2009 to 75% in 2014. The decision time also increased from 3.7 days in 2009 to 6.7 days in 2014. The most common reason for delay in decisions and denials was due to step therapy.14 Insurance companies wanted many patients to try less expensive treatment options prior to “stepping up” to more expensive treatments. Although this may be the case in the treatment of psoriasis, the role of step therapy is unclear for patients with AA because there is only 1 FDA-approved medication. This sets out an ambiguous future for our patients with AA and approval for baricitinib.
The time required for the correspondence between insurance companies, clinic staff, and patients for drug approval may delay treatments, and not all providers have enough staff to coordinate and perform this work. For Black patients, who may present more frequently and with more severe disease,7 this could lead to a health care disparity due to the likelihood of the increased need for biologic treatment. Because Black patients have an increased likelihood of being uninsured or underinsured,15 this further decreases the chances of the most severe AA patients receiving the most helpful medication for their condition.
Many pharmaceutical companies have drug cost assistance programs that aim to provide support covering expensive medications for patients unable to afford them. Although this is a good first step, treatment with any JAK inhibitor potentially can be lifelong. Regarding the social determinants of health, it is known that access to medications does not solely depend on cost. Transportation and access to qualified health professionals are among the issues that create barriers to health care. Instilling long-term practices to ensure equal access to JAK inhibitors and treatment of AA may be the cornerstone to treating AA with equity. Whether we require pharmaceutical companies to make sure all patients have equal access to medications or provide community resources to hairstylists and federally qualified health centers, raising awareness and advocating for and creating attainable access to treatment modalities is imperative to providing well-rounded care to a diverse population.

The most common reason for delay in decisions and denials was due to step therapy.14 Insurance companies wanted many patients to try less expensive treatment options prior to “stepping up” to more expensive treatments. Although this may be the case in the treatment of psoriasis, the role of step therapy is unclear for patients with AA because there is only 1 FDA-approved medication. This sets out an ambiguous future for our patients with AA and approval for baricitinib.
The time required for the correspondence between insurance companies, clinic staff, and patients for drug approval may delay treatments, and not all providers have enough staff to coordinate and perform this work. For Black patients, who may present more frequently and with more severe disease,7 this could lead to a health care disparity due to the likelihood of the increased need for biologic treatment. Because Black patients have an increased likelihood of being uninsured or underinsured,15 this further decreases the chances of the most severe AA patients receiving the most helpful medication for their condition.
Many pharmaceutical companies have drug cost assistance programs that aim to provide support covering expensive medications for patients unable to afford them. Although this is a good first step, treatment with any JAK inhibitor potentially can be lifelong. Regarding the social determinants of health, it is known that access to medications does not solely depend on cost. Transportation and access to qualified health professionals are among the issues that create barriers to health care. Instilling long-term practices to ensure equal access to JAK inhibitors and treatment of AA may be the cornerstone to treating AA with equity. Whether we require pharmaceutical companies to make sure all patients have equal access to medications or provide community resources to hairstylists and federally qualified health centers, raising awareness and advocating for and creating attainable access to treatment modalities is imperative to providing well-rounded care to a diverse population.
With the introduction of the first US Food and Drug Administration (FDA)–approved medication for alopecia areata (AA)—the Janus kinase (JAK) inhibitor, baricitinib—there is an important focus on this disease in the literature and for practicing dermatologists. Known by all as an autoimmune genetic disease that causes relapsing and remitting nonscarring hair loss, AA is a condition where the psychological burden has been less widely recognized. Patients with AA have reported lower health-related quality of life scores compared to patients with other skin conditions, including psoriasis or atopic dermatitis. In addition, a lesser amount of scalp coverage is negatively correlated to health-related quality of life scores.1 Patients with AA also have a 39% lifetime prevalence of major depressive disorder and generalized anxiety disorder.2 The treatment of AA has been a hodgepodge of topical, intralesional, and systemic agents, all with indirect immunosuppressive or anagen prolongation effects. Now that there is an approved therapy for AA with more treatments likely to be approved in the near future, there must be a focus on real-world outcomes. With the dawn of a new era in the treatment of AA as well as new information showcasing an altered prevalence of AA in skin of color, highlighting disparities among this population may help ease challenges dermatologic providers will face.
Efficacy of Baricitinib in Different Races and Ethnicities
How will patients of different races and ethnicities respond to this new treatment, and how will their emotional health be affected? The 2 phase 3 pivotal trials showing efficacy of baricitinib in AA included Black and Latino patients but not in a way that is representative of the US population.3 Until recently, the most commonly used prevalence of AA in the United States was from the NHANES I study completed between 1971 and 1974, which was between 0.1% and 0.2%4 with minimal focus on race and ethnicity. Recent studies suggest that there may be increased prevalence of this condition in Black patients in the United States. These new findings raise concern around access to care and treatment and the need to tailor psychosocial interventions for populations that may not currently have these supports.
A large cross-sectional study published in 2020 demonstrated that these data remained similar, with a lifetime prevalence of 0.21%.5 Of the 45,016 participants—representative of the US population based on the 2015 US Census—the average age of AA patients was 41.2 years, with 61.3% being White and not of Hispanic origin.5 In recent years, other studies have challenged the narrative that AA predominantly affects White patients.6-8 A different cross-sectional study utilizing National Alopecia Areata Registry data from 2002 to 2016 suggested that Black patients have greater odds of developing AA.6 In this study of 2645 cases of AA, the odds ratios of developing the condition were 1.36 for Blacks, 0.53 for Asians, and 0.83 for Hispanics compared with the referent White population. These results were consistent through the varying subtypes of AA.6 In a reply to these findings, Gonzalez and Fleischer7 analyzed data from the 2007 to 2016 National Ambulatory Medical Care Survey database with a focus on racial and ethnic prevalence of AA. This study concluded that Latino and non-White individuals had an increased likelihood of clinician visits for AA compared with White individuals.7
More evidence of the Black predominance of AA was demonstrated in a study published in 2018. In this large-scale study, 63,960 women from the Nurses’ Health Study (NHS) and 88,368 women from the Nurses’ Health Study II (NHSII) were included to examine prevalence of disease among these US women.8 Analysis showed increased odds of AA based on self-reported race in Black and Hispanic women. Lifetime incidence of AA was greater in Black women, with 2.63 and 5.23 in NHS and NHSII, respectively. It was hypothesized that hairstyling practices in Black and Hispanic women may cause AA to be more noticeable,8 which may drive patients to seek medical evaluation.
Feaster and McMichael9 published information on the epidemiology of AA in a busy hair loss clinic. This retrospective single-institution study of 265 pediatric and adult Black patients with AA seen over a 5-year period showed that patients aged 18 to 34 years were most likely to present for care, which accounted for 35.8% of the study population, followed by patients aged 10 to 17 years, which accounted for 15.1%. This study also found that females were the larger segment of AA patients, with an increased distribution of disease in young patients. Most of these patients (68.2%) had patchy hair loss, and the ophiasis pattern was seen in 15.1%.9 Although the pathogenesis of AA is linked to autoimmunity,10 the leading cause for these epidemiologic findings of increased prevalence in Black patients is still uncertain.
Baricitinib for AA
In June 2022, the FDA announced the first biologic drug approved for the treatment of AA—baricitinib. Baricitinib is an oral, selective, reversible inhibitor of JAK1 and JAK2.3 The phase 3 trials for baricitinib—BRAVE-AA1 (N=654) and BRAVE-AA2 (N=546)—were conducted between March 2019 and May 2020. In these double-blind, parallel-group, randomized, placebo-controlled trials, 33% of the patient population receiving baricitinib accomplished 80% or more scalp coverage at 36 weeks. The Severity of Alopecia Tool (SALT) score also decreased to 20 or less in 36 weeks. The BRAVE-AA1 and BRAVE-AA2 trials consisted of a total of 1200 patients, with only 98 identifying as Black. Of these 98 patients, 33 were randomly selected to receive placebo.3 With studies now suggesting that Black individuals have greater odds of AA compared with White individuals6 and Black patients being more likely to seek medical care for AA,7 the BRAVE-AA1 and BRAVE-AA2 study population did not allow for significant comparative data for Black patients. These studies did not document Latino patient involvement.3 Future studies in AA must recruit a diversified group of study participants to better reflect the patients with an increased likelihood of presenting with AA.
Other Treatments on the Horizon
Baricitinib likely will remain alone in its class for only a short time. Phase 3 trials have been completed for ritlecitinib, brepocitinib, and deuruxolitinib for AA. Ritlecitinib, an irreversible inhibitor of JAK3 and the tyrosine kinase expressed in hepatocellular carcinoma (TEC) kinase family, has met all end points in a phase 2b/3 study.11 Brepocitinib is an oral tyrosine kinase 2/JAK1 inhibitor,12 and deuruxolitinib is an investigational JAK1/2 inhibitor for AA.13
Insurance Coverage Considerations and Health Care Disparities
Prior authorizations have been the initial step for many drugs in varying fields of medical practice. A study completed in 2016 suggested that insurance coverage for biologics used in the treatment of psoriasis was becoming increasingly difficult.14 Prior authorization requirement rates increased from 16% of patients in 2009 to 75% in 2014. The decision time also increased from 3.7 days in 2009 to 6.7 days in 2014. The most common reason for delay in decisions and denials was due to step therapy.14 Insurance companies wanted many patients to try less expensive treatment options prior to “stepping up” to more expensive treatments. Although this may be the case in the treatment of psoriasis, the role of step therapy is unclear for patients with AA because there is only 1 FDA-approved medication.

For Black patients, who may present more frequently and with more severe disease,7 this could lead to a health care disparity due to the likelihood of the increased need for biologic treatment. Because Black patients have an increased likelihood of being uninsured or underinsured,15 this further decreases the chances of the most severe AA patients receiving the most helpful medication for their condition.

Oral minoxidil improves anticancer treatment–induced alopecia in women with breast cancer
Topical minoxidil is widely used to treat hair loss, but new findings suggest that
In a retrospective cohort study of women with breast cancer and anticancer therapy–induced alopecia, researchers found that combining low-dose oral minoxidil (LDOM) and topical minoxidil achieved better results than topical minoxidil alone and that the treatment was well tolerated. A total of 5 of the 37 patients (13.5%) in the combination therapy group achieved a complete response, defined as an improvement of alopecia severity from grade 2 to grade 1, compared with none of the 19 patients in the topical therapy–only group.
In contrast, none of the patients in the combination group experienced worsening of alopecia, compared with two (10.5%) in the topical monotherapy group.
The study was published online in the Journal of the American Academy of Dermatology. Topical minoxidil is approved by the Food and Drug Administration to treat androgenetic alopecia. Oral minoxidil is not approved for treating hair loss but has been receiving increased attention as an adjunctive therapy for hair loss, particularly for women. Oral minoxidil is approved for treating hypertension but at much higher doses.
An increasing number of studies have been conducted on the use of oral minoxidil for the treatment of female pattern hair loss, dating back to a pilot study in 2017, with promising results. The findings suggest that LDOM might be more effective than topical therapy, well tolerated, and more convenient for individuals to take.
Hypothesis generating
In a comment, Kai Johnson, MD, a medical oncologist who specializes in treating patients with breast cancer at the Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute, Columbus, noted that the study, like most small-scale retrospective studies, is hypothesis generating. However, “I’d be hesitant to broadly recommend this practice of dual therapy – oral and topical minoxidil together – until we see a placebo-controlled prospective study performed demonstrating clinically meaningful benefits for patients.”
Another factor is the study endpoints. “While there was a statistically significant benefit documented with dual therapy in this study, it’s important to have study endpoints that are more patient oriented,” Dr. Johnson said. The most important endpoint for patients would be improvements “in the actual alopecia grade, which did occur in 5 of the 37 of dual-therapy patients, versus 0 topical minoxidil patients.”
George Cotsarelis, MD, chair of the department of dermatology and professor of dermatology at the University of Pennsylvania, Philadelphia, also weighed in. He questioned whether adding the topical therapy to oral minoxidil actually improved the results. “What was missing was a study arm that used the oral alone,” he said in an interview. “So we don’t know how effective the oral therapy would be by itself and if combining it with the topical is really adding anything.”
Oral minoxidil as a treatment for hair loss is gaining traction, and it’s clear that it is effective. However, the risk of side effects is higher, he said. “The risk isn’t that high with the low dose, but it can grow hair on places other than the scalp, and that can be disconcerting.” In this study, two women who took the oral drug reported edema, and one reported headache and dizziness. Hypertrichosis was reported by five patients who received the combination.
Study details
In the study, Jeewoo Kang, MD, and colleagues from the Seoul National University evaluated the efficacy of LDOM in 100 patients with breast cancer who had been diagnosed with persistent chemotherapy-induced alopecia (pCIA) and endocrine therapy–induced alopecia (EIA) at a dermatology clinic.
They conducted an analysis of medical records, standardized clinical photographs, and trichoscopic images to evaluate the alopecia pattern, severity, treatment response, and posttreatment changes in vertex hair density and thickness.
Compared with those with EIA alone, patients with pCIA were significantly more likely to have diffuse alopecia (P < .001), and they were more likely to have more severe alopecia, although this difference was not significant (P = .058). Outcomes were evaluated for 56 patients who were treated with minoxidil (19 with topical minoxidil alone and 37 with both LDOM and topical minoxidil) and for whom clinical and trichoscopic photos were available at baseline and at the last follow-up (all patients were scheduled for follow-up at 3-month intervals).
The results showed that those treated with 1.25-5.0 mg/d of oral minoxidil and 5% topical minoxidil solution once a day had better responses (P = .002) and a higher percentage increase in hair density from baseline (P = .003), compared with those who received topical minoxidil monotherapy.
However, changes in hair thickness after treatment were not significantly different between the two groups (P = .540).
In addition to the five (13.5%) cases of hypertrichosis, two cases of edema (5.4%), and one case of headache/dizziness (2.7%) among those who received the combination, there was also one report of palpitations (2.7%). Palpitations were reported in one patient (5%) who received topical monotherapy, the only adverse event reported in this group.
Dr. Johnson noted that, at his institution, a dermatologist is conducting a clinical trial with oncology patients post chemotherapy and endocrine therapy. “She is looking at a similar question, although she is comparing oral minoxidil to topical minoxidil directly rather than in combination.” There is also an active clinical trial at Northwestern University, Chicago, of LDOM alone for patients with chemotherapy-induced alopecia.
“So there is a lot of momentum surrounding this concept, and I feel we will continue to see it come up as a possible treatment option, but more data are needed at this time before it can become standard of care,” Dr. Johnson added.
No funding for the study was reported. The authors disclosed no relevant financial relationships.

However, “I’d be hesitant to broadly recommend this practice of dual therapy – oral and topical minoxidil together – until we see a placebo-controlled prospective study performed demonstrating clinically meaningful benefits for patients.”
Another factor is the study endpoints. “While there was a statistically significant benefit documented with dual therapy in this study, it’s important to have study endpoints that are more patient oriented,” Dr. Johnson said. The most important endpoint for patients would be improvements “in the actual alopecia grade, which did occur in 5 of the 37 of dual-therapy patients, versus 0 topical minoxidil patients.”
George Cotsarelis, MD, chair of the department of dermatology and professor of dermatology at the University of Pennsylvania, Philadelphia, also weighed in. He questioned whether adding the topical therapy to oral minoxidil actually improved the results. “What was missing was a study arm that used the oral alone,” he said in an interview. “So we don’t know how effective the oral therapy would be by itself and if combining it with the topical is really adding anything.”
Oral minoxidil as a treatment for hair loss is gaining traction, and it’s clear that it is effective. However, the risk of side effects is higher, he said. “The risk isn’t that high with the low dose, but it can grow hair on places other than the scalp, and that can be disconcerting.” In this study, two women who took the oral drug reported edema, and one reported headache and dizziness. Hypertrichosis was reported by five patients who received the combination.
Study details
In the study, Jeewoo Kang, MD, and colleagues from the Seoul National University evaluated the efficacy of LDOM in 100 patients with breast cancer who had been diagnosed with persistent chemotherapy-induced alopecia (pCIA) and endocrine therapy–induced alopecia (EIA) at a dermatology clinic.
They conducted an analysis of medical records, standardized clinical photographs, and trichoscopic images to evaluate the alopecia pattern, severity, treatment response, and posttreatment changes in vertex hair density and thickness.
Compared with those with EIA alone, patients with pCIA were significantly more likely to have diffuse alopecia (P < .001), and they were more likely to have more severe alopecia, although this difference was not significant (P = .058). Outcomes were evaluated for 56 patients who were treated with minoxidil (19 with topical minoxidil alone and 37 with both LDOM and topical minoxidil) and for whom clinical and trichoscopic photos were available at baseline and at the last follow-up (all patients were scheduled for follow-up at 3-month intervals).
The results showed that those treated with 1.25-5.0 mg/d of oral minoxidil and 5% topical minoxidil solution once a day had better responses (P = .002) and a higher percentage increase in hair density from baseline (P = .003), compared with those who received topical minoxidil monotherapy.
However, changes in hair thickness after treatment were not significantly different between the two groups (P = .540).
In addition to the five (13.5%) cases of hypertrichosis, two cases of edema (5.4%), and one case of headache/dizziness (2.7%) among those who received the combination, there was also one report of palpitations (2.7%). Palpitations were reported in one patient (5%) who received topical monotherapy, the only adverse event reported in this group.
Dr. Johnson noted that, at his institution, a dermatologist is conducting a clinical trial with oncology patients post chemotherapy and endocrine therapy. “She is looking at a similar question, although she is comparing oral minoxidil to topical minoxidil directly rather than in combination.” There is also an active clinical trial at Northwestern University, Chicago, of LDOM alone for patients with chemotherapy-induced alopecia.
“So there is a lot of momentum surrounding this concept, and I feel we will continue to see it come up as a possible treatment option, but more data are needed at this time before it can become standard of care,” Dr. Johnson added.
No funding for the study was reported. The authors disclosed no relevant financial relationships.

Study evaluates features of alopecia areata in Hispanic/Latinx patients
.
Those are among key findings from a retrospective analysis of Hispanic/Latinx patients at the University of California, Irvine (UCI) by Natasha Mesinkovska, MD, PhD, of UCI’s department of dermatology, and her coauthors. The findings were published online in the Journal of the American Academy of Dermatology.
A recent study examined the epidemiology of alopecia areata (AA) in Black patients, wrote Dr. Mesinkovska and coauthors Celine Phong, a UCI medical student, and Amy J. McMichael, MD, professor of dermatology at Wake Forest University, Winston-Salem, N.C. “A similar unmet need exists to describe the characteristics of AA in Hispanic/Latinx (H/L) patients, the prevalent majority in California,” they added.
Drawing from chart reviews, ICD codes, and documented physical exams, they retrospectively identified 197 Hispanic/Latinx patients diagnosed with AA at UCI between 2015 and 2022, including alopecia totalis and alopecia universalis.
Nearly two-thirds of patients with alopecia were female (63%), and their mean age at diagnosis was 33 years. Most patients (79%) presented with patchy pattern AA, 13% had diffuse pattern AA, and only 12% had eyebrow, eyelash, or beard involvement. The most common comorbidity in patients overall was atopy (24%), including allergic rhinitis (12%), asthma (10%), and/or atopic dermatitis (7%).
The authors found that 18% of patients had one or more coexisting autoimmune conditions, most commonly rheumatoid arthritis (9%) and thyroid disease (6%). No patients had celiac disease, myasthenia gravis, or inflammatory bowel disease, but 43% had another dermatologic condition.
In other findings, 22% of patients had vitamin D deficiency, 20% had hyperlipidemia, 18% had obesity, 16% had gastroesophageal reflux disease, and 12% had anemia. At the same time, depression, anxiety, or sleep disorders were identified in 14% of patients.
“Interestingly, the most common autoimmune comorbidity in H/L was rheumatoid arthritis, compared to thyroid disease in Black patients and overall AA patients,” the authors wrote. “This finding may be a reflection of a larger trend, as rheumatoid arthritis in the H/L population has been on the rise.”
The authors acknowledged certain limitations of the study including its small sample size and lack of a control group, and reported having no financial disclosures.
