Hair & Nails

The major classifications of thyroid disease include hyperthyroidism, which is seen in Graves disease, and hypothyroidism due to iodine deficiency and Hashimoto thyroiditis, which have potentially devastating health consequences. The prevalence of hyperthyroidism ranges from 0.2% to 1.3% in iodine-sufficient parts of the world, and the prevalence of hypothyroidism in the general population is 5.3% in Europe and 3.7% in the United States.¹ Thyroid hormones physiologically potentiate α- and β-adrenergic receptors by increasing their sensitivity to catecholamines. Excess thyroid hormones manifest as tachycardia, increased cardiac output, increased body temperature, hyperhidrosis, and warm moist skin. Reduced sensitivity of adrenergic receptors to catecholamines from insufficient thyroid hormones results in a lower metabolic rate and decreases response to the sympathetic nervous system.² Nail changes in thyroid patients have not been well studied.³ Our objectives were to characterize nail findings in patients with thyroid disease. Early diagnosis of thyroid disease and prompt referral for treatment may be instrumental in preventing serious morbidities and permanent sequelae.

Methods

PubMed, Scopus, Web of Science, and Google Scholar were searched for the terms nail + thyroid, nail + hyperthyroid, nail + hypothyroid, nail + Graves, and nail + Hashimoto on June 10, 2020, and then updated on November 18, 2020. All English-language articles were included. Non–English-language articles and those that did not describe clinical trials of nail changes in patients with thyroid disease were excluded. One study that utilized survey-based data for nail changes without corroboration with physical examination findings was excluded. Hypothyroidism/hyperthyroidism was defined by all authors as measurement of serum thyroid hormones triiodothyronine, thyroxine, and thyroid-stimulating hormone outside of the normal range. Eight studies were included in the final analysis. Patient demographics, thyroid disease type, physical examination findings, nail clinical findings, age at diagnosis, age at onset of nail changes, treatments/medications, and comorbidities were recorded and analyzed.

Results

Nail changes in patients with thyroid disease were reported in 8 studies (7 cross-sectional, 1 retrospective cohort) and are summarized in the Table.^4-11 The mean age was 41.2 years (range, 5–80 years), with a higher representation of females (range, 70%–94% female). The most common nail changes in thyroid patients were koilonychia, clubbing, and nail brittleness. Other changes included onycholysis, thin nails, dryness, and changes in nail growth rate. Frequent physical findings were xerosis, pruritus, and alopecia.

Both koilonychia and clubbing were reported in patients with hyperthyroidism. In a study of 32 patients with koilonychia, 22 (68.8%) were diagnosed with hyperthyroidism.¹⁰ Nail clubbing affected 7.3% of Graves disease patients (n=150)⁶ and 5.0% of hyperthyroid patients (n=120).⁷ Dermopathy presented more than 1 year after diagnosis of Graves disease in 99 (66%) of 150 patients as a late manifestation of thyrotoxicosis.⁶ Additional physical features in patients with Graves disease (n=150) were pretibial myxedema (100%), ophthalmopathy (99.0%), and proptosis (88.0%). Non–Graves hyperthyroid patients showed physical features of soft hair (83.3%) and soft skin (66.0%).⁷

Nail brittleness was a frequently reported nail change in thyroid patients (4/8 studies, 50%), most often seen in 22% of autoimmune patients, 19.6% of nonautoimmune patients, 13.9% of hypothyroid patients, and 9.2% of hyperthyroid patients.^5,8 For comparison, brittle nails presented in 10.8% of participants in a control group.⁵ Brittle nails in thyroid patients often are accompanied by other nail findings such as thinning, onycholysis, and pitting.

Among hypothyroid patients, nail changes included fragility (70%; n=50), slow growth (48%; n=50), thinning (40%; n=50), onycholysis (38%; n=50),⁷ and brittleness (13.9%; n=173).⁵ Less common nail changes in hypothyroid patients were leukonychia (9.4%; n=32), striped nails (6%; n=50), and pitting (1.2%; n=173).^5,7,11 Among hyperthyroid patients, the most common nail changes were koilonychia (100%; n=22), softening (83%; n=120), onycholysis (29%; n=14), and brittleness (9.2%; n=173).^5,7,9,10 Less common nail changes in hyperthyroid patients were clubbing (5%; n=120), thinning (4.6%; n=173), and leukonychia (3%; n=120).^5,7

Additional cutaneous findings of thyroid disorder included xerosis, alopecia, pruritus, and weight change. Xerosis was most common in hypothyroid disease (57.2%; n=460).⁴ In 2 studies,^8,9 alopecia affected approximately 70% of autoimmune, nonautoimmune, and hyperthyroid patients. Hair loss was reported in 42.6% (n=460)⁴ and 33.0% (n=36)⁹ of hypothyroid patients. Additionally, pruritus affected up to 28% (n=32)¹¹ of hypothyroid and 16.0% (n=120)⁷ of hyperthyroid patients and was more common in autoimmune (41%) vs nonautoimmune (32%) thyroid patients.⁸ Weight gain was seen in 72% of hypothyroid patients (n=32),¹¹ and soft hair and skin were reported in 83.3% and 66% of hyperthyroid patients (n=120), respectively.⁷ Flushing was a less common physical finding in thyroid patients (usually affecting <10%); however, it also was reported in 17.1% of autoimmune and 57.1% of hyperthyroid patients from 2 separate studies.^8,9

There are limited data describing nail changes with thyroid disease. Singal and Arora³ reported in their clinical review of nail changes in systemic disease that koilonychia, onycholysis, and melanonychia are associated with thyroid disorders. We similarly found that koilonychia and onycholysis are associated with thyroid disorders without an association with melanonychia.

In his clinical review of thyroid hormone action on the skin, Safer¹² described hypothyroid patients having coarse, dull, thin, and brittle nails, whereas in thyrotoxicosis, patients had shiny, soft, and concave nails with onycholysis; however, the author commented that there were limited data on the clinical findings in thyroid disorders. These nail findings are consistent with our results, but onycholysis was more common in hypothyroid patients than in hyperthyroid patients in our review. Fox¹³ reported on 30 cases of onycholysis, stating that it affected patients with hypothyroidism and improved with thyroid treatment. In a clinical review of 8 commonly seen nail abnormalities, Fowler et al¹⁴ reported that hyperthyroidism was associated with nail findings in 5% of cases and may result in onycholysis of the fourth and fifth nails or all nails. They also reported that onychorrhexis may be seen in patients with hypothyroidism, a finding that differed from our results.¹⁴

The mechanism of nail changes in thyroid disease has not been well studied. A protein/amino acid–deficiency state may contribute to the development of koilonychia. Hyperthyroid patients, who have high metabolic activity, may have hypoalbuminemia, leading to koilonychia.¹⁵ Hypothyroidism causes hypothermia from decreased metabolic rate and secondary compensatory vasoconstriction. Vasoconstriction decreases blood flow of nutrients and oxygen to cutaneous structures and may cause slow-growing, brittle nails. In hyperthyroidism, vasodilation alternatively may contribute to the fast-growing nails. Anti–thyroid-stimulating hormone receptor antibodies in Graves disease may increase the synthesis of hyaluronic acid and glycosaminoglycans from fibroblasts, keratinocytes, adipocytes, or endothelial cells in the dermis and may contribute to development of clubbing.¹⁶

Our review is subject to several limitations. We recorded nail findings as they were described in the original studies; however, we could not confirm the accuracy of these descriptions. In addition, some specific nail changes were not described in sufficient detail. In all but 1 study, dermatologists performed the physical examination. In the study by Al-Dabbagh and Al-Abachi,¹⁰ the physical examinations were performed by general medicine physicians, but they selected only for patients with koilonychia and did not assess for other skin findings. Fragile nails and brittle nails were described in hypothyroid and hyperthyroid patients, but these nail changes were not described in detail. There also were studies describing nail changes in thyroid patients; some studies had small numbers of patients, and many did not have a control group.

Conclusion

Nail changes may be early clinical presenting signs of thyroid disorders and may be the clue to prompt diagnosis of thyroid disease. Dermatologists should be mindful that fragile, slow-growing, thin nails and onycholysis are associated with hypothyroidism and that koilonychia, softening, onycholysis, and brittle nail changes may be seen in hyperthyroidism. Our review aimed to describe nail changes associated with thyroid disease to guide dermatologists on diagnosis and promote future research on dermatologic manifestations of thyroid disease. Future research is necessary to explore the association between koilonychia and hyperthyroidism as well as the association of nail changes with thyroid disease duration and severity.

As residents, it is important to understand the steps of the manicuring process and be able to inform patients on how to maintain optimal nail health while continuing to go to nail salons. Most patients are not aware of the possible allergic, traumatic, and/or infectious complications of manicuring their nails. There are practical steps that can be taken to prevent nail issues, such as avoiding cutting one’s cuticles or using allergen-free nail polishes. These simple fixes can make a big difference in long-term nail health in our patients.

Nail Polish Application Process

The nails are first soaked in a warm soapy solution to soften the nail plate and cuticles.¹ Then the nail tips and plates are filed and occasionally are smoothed with a drill. The cuticles are cut with a cuticle cutter. Nail polish—base coat, color enamel, and top coat—is then applied to the nail. Acrylic or sculptured nails and gel and dip manicures are composed of chemical monomers and polymers that harden either at room temperature or through UV or light-emitting diode (LED) exposure. The chemicals in these products can damage nails and cause allergic reactions.

Contact Dermatitis

Approximately 2% of individuals have been found to have allergic or irritant contact dermatitis to nail care products. The top 5 allergens implicated in nail products are (1) 2-hydroxyethyl methacrylate, (2) methyl methacrylate, (3) ethyl acrylate, (4) ethyl-2-cyanoacrylate, and (5) tosylamide.² Methyl methacrylate was banned in 1974 by the US Food and Drug Administration due to reports of severe contact dermatitis, paronychia, and nail dystrophy.³ Due to their potent sensitizing effects, acrylates were named the contact allergen of the year in 2012 by the American Contact Dermatitis Society.³

Acrylates are plastic products formed by polymerization of acrylic or methacrylic acid.⁴ Artificial sculptured nails are created by mixing powdered polymethyl methacrylate polymers and liquid ethyl or isobutyl methacrylate monomers and then applying this mixture to the nail plate.⁵ Gel and powder nails employ a mixture that is similar to acrylic powders, which require UV or LED radiation to polymerize and harden on the nail plate.

Tosylamide, or tosylamide formaldehyde resin, is another potent allergen that promotes adhesion of the enamel to the nail.⁶ It is important to note that sensitization may develop months to years after using artificial nails.

Clinical features of contact allergy secondary to nail polish can vary. Some patients experience severe periungual dermatitis. Others can present with facial or eyelid dermatitis due to exposure to airborne particles of acrylates or from contact with fingertips bearing acrylic nails.^6,7 If inhaled, acrylates also can cause wheezing asthma or allergic rhinoconjunctivitis.

Common Onychodystrophies

Damage to the natural nail plate is inevitable with continued wear of sculptured nails. With 2 to 4 months of consecutive wear, the natural nails turn yellow, brittle, and weak.⁵ One study noted that the thickness of an individual’s left thumb nail plate thinned from 0.059 cm to 0.03 cm after a gel manicure was removed from the nail.⁸ Nail injuries due to manicuring include keratin granulations, onycholysis, pincer nail deformities, pseudopsoriatic nails, lamellar onychoschizia, transverse leukonychia, and ingrown nails.⁶ One interesting nail dystrophy reported secondary to gel manicures is pterygium inversum unguis or a ventral pterygium that causes an abnormal painful adherence of the hyponychium to the ventral surface of the nail plate. Patients prone to developing pterygium inversum unguis can experience sensitivity, pain, or burning sensations during LED or UVA light exposure.⁹

Infections

In addition to contact allergies and nail dystrophies, each step of the manicuring process, such as cutting cuticles, presents opportunities for infectious agents to enter the nail fold. Acute or chronic paronychia, or inflammation of the nail fold, most commonly is caused by bacterial infections with Staphylococcus aureus. Green nail syndrome caused by Pseudomonas aeruginosa also is common.¹ Onychomycosis due to Trichophyton rubrum is one of the most frequent fungal infections contracted at nail salons. Mycobacteria such as Mycobacterium fortuitum also have been implicated in infections from salons, as they can be found in the jets of pedicure spas, which are not sanitized regularly.¹⁰

Final Thoughts

Nail cosmetics are an integral part of many patients’ lives. Being able to educate yourself and your patients on the hazards of nail salons can help them avoid painful infections, contact allergies, and acute to chronic nail deformities. It is important for residents to be aware of the different dermatoses that can arise in men and women who frequent nail salons as the popularity of the nail beauty industry continues to rise.

Acrylates are plastic products formed by polymerization of acrylic or methacrylic acid.⁴ Artificial sculptured nails are created by mixing powdered polymethyl methacrylate polymers and liquid ethyl or isobutyl methacrylate monomers and then applying this mixture to the nail plate.⁵ Gel and powder nails employ a mixture that is similar to acrylic powders, which require UV or LED radiation to polymerize and harden on the nail plate.

Tosylamide, or tosylamide formaldehyde resin, is another potent allergen that promotes adhesion of the enamel to the nail.⁶ It is important to note that sensitization may develop months to years after using artificial nails.

Clinical features of contact allergy secondary to nail polish can vary. Some patients experience severe periungual dermatitis. Others can present with facial or eyelid dermatitis due to exposure to airborne particles of acrylates or from contact with fingertips bearing acrylic nails.^6,7 If inhaled, acrylates also can cause wheezing asthma or allergic rhinoconjunctivitis.

Common Onychodystrophies

Damage to the natural nail plate is inevitable with continued wear of sculptured nails. With 2 to 4 months of consecutive wear, the natural nails turn yellow, brittle, and weak.⁵ One study noted that the thickness of an individual’s left thumb nail plate thinned from 0.059 cm to 0.03 cm after a gel manicure was removed from the nail.⁸ Nail injuries due to manicuring include keratin granulations, onycholysis, pincer nail deformities, pseudopsoriatic nails, lamellar onychoschizia, transverse leukonychia, and ingrown nails.⁶ One interesting nail dystrophy reported secondary to gel manicures is pterygium inversum unguis or a ventral pterygium that causes an abnormal painful adherence of the hyponychium to the ventral surface of the nail plate. Patients prone to developing pterygium inversum unguis can experience sensitivity, pain, or burning sensations during LED or UVA light exposure.⁹

Infections

In addition to contact allergies and nail dystrophies, each step of the manicuring process, such as cutting cuticles, presents opportunities for infectious agents to enter the nail fold. Acute or chronic paronychia, or inflammation of the nail fold, most commonly is caused by bacterial infections with Staphylococcus aureus. Green nail syndrome caused by Pseudomonas aeruginosa also is common.¹ Onychomycosis due to Trichophyton rubrum is one of the most frequent fungal infections contracted at nail salons. Mycobacteria such as Mycobacterium fortuitum also have been implicated in infections from salons, as they can be found in the jets of pedicure spas, which are not sanitized regularly.¹⁰

Final Thoughts

Nail cosmetics are an integral part of many patients’ lives. Being able to educate yourself and your patients on the hazards of nail salons can help them avoid painful infections, contact allergies, and acute to chronic nail deformities. It is important for residents to be aware of the different dermatoses that can arise in men and women who frequent nail salons as the popularity of the nail beauty industry continues to rise.

As residents, it is important to understand the steps of the manicuring process and be able to inform patients on how to maintain optimal nail health while continuing to go to nail salons. Most patients are not aware of the possible allergic, traumatic, and/or infectious complications of manicuring their nails. There are practical steps that can be taken to prevent nail issues, such as avoiding cutting one’s cuticles or using allergen-free nail polishes. These simple fixes can make a big difference in long-term nail health in our patients.

Nail Polish Application Process

The nails are first soaked in a warm soapy solution to soften the nail plate and cuticles.¹ Then the nail tips and plates are filed and occasionally are smoothed with a drill. The cuticles are cut with a cuticle cutter. Nail polish—base coat, color enamel, and top coat—is then applied to the nail. Acrylic or sculptured nails and gel and dip manicures are composed of chemical monomers and polymers that harden either at room temperature or through UV or light-emitting diode (LED) exposure. The chemicals in these products can damage nails and cause allergic reactions.

Contact Dermatitis

Approximately 2% of individuals have been found to have allergic or irritant contact dermatitis to nail care products.

INDIANAPOLIS – Despite the common prevalence of skin-picking disorder and trichotillomania (hair pulling), no Food and Drug Administration–approved treatments exist for either condition.

And while both body-focused repetitive behavior disorders affect a greater proportion of females than males, “we have no current information that is useful about what hormonal influences may or may not play in terms of picking and pulling behaviors,” Jon E. Grant, MD, JD, MPH, professor of psychiatry and behavioral neuroscience at the University of Chicago, said at the annual meeting of the Society for Pediatric Dermatology. “On a cognitive level, affected children and adolescents often have impaired inhibitory control but they are often 1-2 standard deviations above average IQ. They have Type A personalities [and are] very driven young kids. They also do not tolerate any down time or boredom. They need to be doing something all the time.”

According to the DSM-5, the diagnostic criteria for skin picking includes recurrent skin picking that results in skin lesions and is not attributable to another medical condition or substance. It also involves repeated attempts to decrease or stop the behavior and causes clinically significant distress or impairment.

“The other medical condition that we are interested in is the misuse of or dependence upon amphetamines or other prescription-based or illicit stimulants,” Dr. Grant said. “I saw a young man who was using about 600 mg of Ritalin a day, and he was picking all over the place. He did not have a primary skin disorder.”

The lifetime prevalence of skin picking disorder ranges between 1.4% and 5.4% of the general population. However, about 63% of people in a community sample endorsed some form of skin picking, and in a study of 105 college students, almost 40% said they picked their skin and had noticeable tissue damage as a result.

“Skin picking is not the same as self-injury,” Dr. Grant said. “It is also not simply an anxiety disorder. Anxiety will make people who pick worse, so people will say that they pick when they’re under stress. I can give them benzodiazepines and they’re still going to pick.”

Animal and human studies demonstrate that skin picking and hair pulling primarily affect females. “You will encounter young boys that pick and pull, but it largely affects females, and it tends to start around puberty,” he said. “Picking can have an onset after the age of 30, which is quite uncommon.”

From a cognitive standpoint, pathological skin pickers demonstrate impaired inhibitory control, impaired stop signal reaction time, increased rates of negative urgency (a tendency to act impulsively in response to negative emotions), and increased rates of positive urgency (a tendency to act impulsively in response to exciting or pleasurable emotions).

Trichotillomania

The lifetime prevalence of trichotillomania ranges between 0.6% and 3.9%. The onset is typically from ages 10-13 years, and the mean duration of illness is 22 years.

The DSM-5 criteria for trichotillomania are similar to that of skin-picking disorder, “although we don’t really worry about the substance use issue with people who pull their hair,” Dr. Grant said. “It doesn’t seem to have a correlation.” In addition, sometimes, children “will worsen pulling or picking when they have co-occurring ADHD and they’ve been started on a stimulant, even at a typical dose. For kids who have those issues, we prefer to try nonstimulant options for their ADHD such as bupropion or atomoxetine.”

Individuals with trichotillomania also tend to have low self-esteem and increased social anxiety, he added, and about one-third report low or very low quality of life. “When you notice alopecia, particularly in young girls who often have longer hair, up to 20% will eat their hair,” Dr. Grant said. “We don’t know why. It’s not related to vitamin deficiencies; it’s not a pica type of iron deficiency. There seems to be a shame piece about eating one’s own hair, but it’s important to assess that. Ask about constipation or overflow incontinence because they can get a bezoar, which can rupture” and can be fatal.

Skin-picking disorder and trichotillomania co-occur in up to 20% of cases. “When they do it tends to be a more difficult problem,” he said. These patients often come for mental health care because of depression, and most, he added, say “I don’t think I would be depressed if I wasn’t covered with excoriations or missing most of my hair.”
 

Treatment for both conditions

According to Dr. Grant, the treatment of choice for skin-picking disorder and trichotillomania is a specific psychotherapy known as “habit reversal therapy,” which involves helping the patient gain better self-control. The drawback is that it’s difficult to find someone trained in habit reversal therapy, “who know anything about skin picking and hair pulling,” he said. “That has been a huge challenge in the field.”

In his experience, the medical treatment of choice for skin-picking disorder and trichotillomania is N-acetylcysteine, an over-the-counter amino acid and antioxidant, which has been shown to be helpful at a dose of 2,400 mg per day. “Patients report to me that some of the excoriations clear up a little quicker as they’re taking it,” Dr. Grant said.

There may also be a role for antipsychotic therapy, he said, “but because of the associated weight gain with most antipsychotics we prefer not to use them.”

The opioid antagonist naltrexone has been shown to be effective in the subset of patients with skin-picking or hair-pulling disorders whose parents have a substance use disorder, Dr. Grant said. “The thought is that there’s something addictive about this behavior in some kids. These kids will look forward to picking and find it rewarding and exciting.”

Dr. Grant reported having no relevant financial disclosures.

Compulsivity is a significant contributor to disability and poor quality of life for individuals with trichotillomania (TTM) and skin-picking disorder (SPD), based on data from 91 adults.

Although body-focused repetitive behaviors (BFRBs), specifically trichotillomania and skin-picking disorder, are similar in clinical presentation to aspects of obsessive-compulsive disorder (OCD), the role of compulsivity in TTM and SPD has not been well studied, wrote Jon E. Grant, MD, of the University of Chicago and colleagues.

In a study published in the Journal of Psychiatric Research, the authors recruited 69 women and 22 men who met DSM-5 criteria for TTM and SPD. Participants completed diagnostic interviews, symptom inventories, and measures of disability/functioning. Compulsivity was measured using the 15-item Cambridge-Chicago Compulsivity Trait Scale (CHI-T). The average age of the participants was 30.9 years; 48 had TTM, 37 had SPD, and 2 had both conditions.

Overall, total CHI-T scores were significantly correlated with worse disability and quality of life, based on the Quality of Life Inventory (P = .0278) and the Sheehan Disability Scale (P = .0085) but not with severity of TTM or SPD symptoms. TTM and SPD symptoms were assessed using the Massachusetts General Hospital Hair Pulling Scale and the Skin Picking Symptom Symptom Assessment Scale.

“In the current study, we did not find a link between conventional symptom severity measures for BFRBs and disability or quality of life, whereas trans-diagnostic compulsivity did correlate with these clinically important parameters,” the researchers wrote in their discussion. “These findings might suggest the current symptom measures for BFRBs are not including an important aspect of the disease and that a fuller understanding of these symptoms requires measurement of compulsivity. Including validated measures of compulsivity in clinical trials of therapy or medication would also seem to be important for future work,” they said.

The study findings were limited by several factors including the use of a community sample that may not generalize to a clinical setting, the researchers noted. Other limitations include the cross-sectional design, which prevents conclusions about causality, the lack of a control group, and the relatively small sample size, they said.

However, the study is the first known to use a validated compulsivity measure to assess BFRBs, and the results suggest a clinically relevant impact of compulsivity on both psychosocial dysfunction and poor quality of life in this patient population, with possible implications for treatment, the researchers wrote.

The study received no outside funding. Lead author Dr. Grant disclosed research grants from Otsuka and Biohaven Pharmaceuticals, yearly compensation from Springer Publishing for acting as editor in chief of the Journal of Gambling Studies, and royalties from Oxford University Press, American Psychiatric Publishing, Norton Press, and McGraw Hill.

Dermatologists, who recently celebrated the Food and Drug Administration’s approval of the world’s first oral systemic treatment for adults with severe alopecia areata (AA), are now looking ahead to the practicalities of getting the drug to eligible patients.

On June 13, the FDA approved baricitinib, a Janus kinase inhibitor (Olumiant, Lilly), for severe AA, and two other options may not be far behind. Pfizer and Concert Pharmaceuticals have JAK inhibitors in late-stage development for AA. JAK inhibitors, including baricitinib, are already on the market for treating rheumatoid arthritis and other autoimmune diseases.

Meanwhile, dermatologists have been fielding calls from hopeful patients and sorting out who should get the treatment, how to advise patients on risks and benefits, and what tests should be used before and after starting treatment.

Uptake for new systemic drugs, such as biologics, can be slow in dermatology, noted Adam Friedman, MD, professor and chair of dermatology, George Washington University, Washington, as some doctors like to stick with what they know.

He told this news organization that he hopes that uptake for baricitinib is quicker, as it is the only approved oral systemic treatment for patients with severe alopecia areata, which affects about 300,000 people a year in the United States. Other treatments, including steroid injections in the scalp, have lacked efficacy and convenience.

Beyond the physical effects, the mental toll of patchy hair clumps and missing brows and lashes can be devastating for patients with alopecia areata.
 

Fielding patient inquiries

Word of the FDA approval spread fast, and calls and emails are coming into dermatologists’ offices and clinics from interested patients.

Physicians should be ready for patients with any kind of hair loss, not just severe alopecia areata, to ask about the drug, Dr. Friedman said. Some patients contacting him don’t fit the indication, which “highlights how disabling hair loss” is for people, considering that, in general, “people see this and think it is for them.”

Baricitinib is not a new drug, but a drug with a new indication. It had already been approved for treating moderate to severe RA in patients who have had an inadequate response to one or more tumor necrosis factor blockers, and for treating COVID-19 in certain hospitalized adults. 
 

Boxed warning

Patients may ask about the boxed warning in the baricitinib label about the increased risk for serious infections, mortality, malignancy, major adverse cardiovascular events, and thrombosis.

Natasha A. Mesinkovska, MD, PhD, an investigator in the clinical trials that led to FDA approval of baricitinib and the chief scientific officer at the National Alopecia Areata Foundation, told this news organization that several aspects of the label are important to point out.

One is that the warning is for all the JAK inhibitors used to treat RA and other inflammatory conditions, not just baricitinib. Also, the warning is based mostly on data on patients with RA who, she noted, have substantial comorbidities and have been taking toxic immunosuppressive medications. The RA population is also typically many years older than the alopecia areata population.

“Whether the warnings apply to the alopecia areata patients is as yet unclear,” said Dr. Mesinkovska, who is also an associate professor of dermatology at the University of California, Irvine.

Patients are also asking about how well it works.

In one of the two trials that led up to the FDA approval, which enrolled patients with at least 50% scalp hair loss for over 6 months, 22% of the patients who received 2 mg of baricitinib and 35% of those who received 4 mg saw adequate hair coverage (at least 80%) at week 36, compared with 5% on placebo. In the second trial, 17% of those who received 2 mg and 32% who received 4 mg saw adequate hair coverage, compared with 3% on placebo.

Common side effects associated with baricitinib, according to the FDA, are lower respiratory tract infections, headache, acne, high cholesterol, increased creatinine phosphokinase, urinary tract infection, liver enzyme elevations, folliculitis, fatigue, nausea, genital yeast infections, anemia, neutropenia, abdominal pain, herpes zoster (shingles), and weight gain.

The risk-benefit discussions with patients should also include potential benefits beyond hair regrowth on the scalp. Loss of hair in the ears and nose can affect hearing and allergies, Dr. Mesinkovska said.

“About 30%-50% with alopecia areata, depending on age group or part of the world, will have allergies,” she said.

Patients should also know that baricitinib will need to be taken “for a very long time,” Dr. Mesinkovska noted. It’s possible that could be forever and that stopping the medication at any point may result in hair falling out again, she says, but duration will vary from case to case.

The good news is that it has been well tolerated. “We give a lot of medications for acne like doxycycline and other antibiotics and people have more stomach problems and angst with those than with [baricitinib],” she said.

Regrowth takes time

Benjamin Ungar, MD, a dermatologist at the Alopecia Center of Excellence at Mount Sinai, New York, told this news organization that an important message for patients is that hair regrowth takes time. For some other skin conditions, patients start treatment and see almost instant improvement.

“That is not the case for alopecia areata,” he said. “The expectation is that it will take months for regrowth in general.”

He said he hasn’t started prescribing baricitinib yet, but plans to do so soon.

“Obviously, I’ll have conversations with patients about it, but it’s a medication I’m going to be using, definitely. I have no reservations,” Dr. Ungar said.

After initial testing, physicians may find that some patients might not be ideal candidates, he added. People with liver disease, a history of blood clots, abnormal blood counts, or low neutrophils are among those who may not be the best candidates for baricitinib.

For most with severe alopecia areata, though, baricitinib provides hope.

“Treatment options have been not readily available, often inaccessible, ineffective, often dangerous,” he said. “There’s a treatment now that can be accessed, generally is safe and is effective for many people.”
 

Be up front with patients about the unknown

Additionally, it’s important to tell patients what is not yet known, the experts interviewed say.

“Alopecia areata is a chronic disease. We don’t have long-term data on the patient population yet,” Dr. Friedman said.

Also unknown is how easy it will be for physicians to get insurance to reimburse for baricitinib, which, at the end of June, was priced at about $5,000 a month for the 4-mg dose. FDA approval was important in that regard. Previously, some claims had been rejected for drugs used off label for AA.

“We dermatologists know how much it affects patients,” Dr. Mesinkovska said. “As long as we stick by what we know and convey to insurers how much it affects people’s lives, they should cover it.”

Another unknown is what other drugs can be taken with baricitinib. In clinical trials, it was used alone, she said. Currently, concomitant use of other immune suppressants – such as methotrexate or prednisone – is not recommended. But it remains to be seen what other medications will be safe to use at the same time as more long-term data are available.

Lynne J. Goldberg, MD, professor of dermatology, pathology, and laboratory medicine, Boston University, and director of the Hair Clinic at Boston Medical Center, said that she received a slew of emails from patients asking about baricitinib, but most of them did not have alopecia areata and were not candidates for this treatment.

She said that nurses in her clinic have been instructed on what to tell patients about which patients the drug is meant to treat, side effects, and benefits.
 

Access won’t be immediate

Dr. Goldberg said the drug’s approval does not mean immediate access. The patient has to come in, discuss the treatment, and get lab tests first. “It’s not a casual drug. This is a potent immunosuppressant drug. You need lab tests and once you start it you need blood tests every 3 months to stay on it.”

Those tests may vary by physician, but people will generally need a standard blood count and a comprehensive metabolic panel and lipid panel. “There’s nothing esoteric,” she said.

She added that physicians will need to check for presence of infections including tuberculosis and hepatitis B and C before prescribing, just as they would before they start prescribing a biologic.

“You don’t want to reactivate something,” she noted.

But, Dr. Goldberg added, the benefits for all who have been either living with only patches of hair or no hair or who put on a wig or hat every day are “life changing.”

Dr. Mesinkovska is on the advisory boards and runs trials for Eli Lilly, Pfizer, and Concert Pharmaceuticals. Dr. Friedman, Dr. Goldberg, and Dr. Ungar reported no relevant financial relationships.

Dermatologists, who recently celebrated the Food and Drug Administration’s approval of the world’s first oral systemic treatment for adults with severe alopecia areata (AA), are now looking ahead to the practicalities of getting the drug to eligible patients.

On June 13, the FDA approved baricitinib, a Janus kinase inhibitor (Olumiant, Lilly), for severe AA, and two other options may not be far behind. Pfizer and Concert Pharmaceuticals have JAK inhibitors in late-stage development for AA. JAK inhibitors, including baricitinib, are already on the market for treating rheumatoid arthritis and other autoimmune diseases.

Meanwhile, dermatologists have been fielding calls from hopeful patients and sorting out who should get the treatment, how to advise patients on risks and benefits, and what tests should be used before and after starting treatment.

Uptake for new systemic drugs, such as biologics, can be slow in dermatology, noted Adam Friedman, MD, professor and chair of dermatology, George Washington University, Washington, as some doctors like to stick with what they know.

He told this news organization that he hopes that uptake for baricitinib is quicker, as it is the only approved oral systemic treatment for patients with severe alopecia areata, which affects about 300,000 people a year in the United States. Other treatments, including steroid injections in the scalp, have lacked efficacy and convenience.

Beyond the physical effects, the mental toll of patchy hair clumps and missing brows and lashes can be devastating for patients with alopecia areata.

“No matter who the patient is, whether a child, adolescent, or adult, the key to figuring out hair disease is getting a good history,” Maria Hordinsky, MD, professor and chair of the department of dermatology at the University of Minnesota, Minneapolis, said at the Medscape Live Women’s and Pediatric Dermatology Seminar.

During her presentation on what’s new in hair disorders, Dr. Hordinsky covered a range of disorders and treatments, with some common denominators, such as the need for a good history. She also urged physicians and other health care providers to use the electronic medical record and to be thorough in documenting information – noting nutrition, hair care habits, supplement use, and other details.

Lab tests should be selected based on that history, she said. For instance, low iron stores can be associated with hair shedding; and thyroid function studies might be needed.

Other highlights of her presentation included comments on different types of alopecia, and some new treatment approaches:

Androgenetic alopecia. In a meta-analysis and systematic review published in 2017, all treatments tested (2% and 5% minoxidil in men, 1 mg finasteride in men, 2% minoxidil in women, and low-level laser light therapy in men) were superior to placebo. Several photobiomodulation (PBM) devices (also known as low-level laser light) for home use have been cleared for androgenetic alopecia by the Food and Drug Administration; a clinician’s guide, published in 2018, provides information on these devices.

Hair and hormones. Combination therapy for female-pattern hair loss – low-dose minoxidil and spironolactone – is important to know about, she said, adding there are data from an observational pilot study supporting this treatment. Women should not become pregnant while on this treatment, Dr. Hordinsky cautioned.

PRP (platelet rich plasma). This treatment for hair loss can be costly, she cautioned, as it’s viewed as a cosmetic technique, “but it actually can work rather well.”

Hair regrowth measures. Traditionally, measures center on global assessment, the patient’s self-assessment, investigator assessment, and an independent photo review. Enter the dermatoscope. “We can now get pictures as a baseline. Patients can see, and also see the health of their scalp,” and if treatments make it look better or worse, she noted.

Alopecia areata (AA). Patients and families need to be made aware that this is an autoimmune disease that can recur, and if it does recur, the extent of hair loss is not predictable. According to Dr. Hordinsky, the most widely used tool to halt disease activity has been treatment with a corticosteroid (topical, intralesional, oral, or even intravenous corticosteroids).

Clinical trials and publications from 2018 to 2020 have triggered interest in off-label use and further studies of JAK inhibitors for treating AA, which include baricitinib, ruxolitinib, and tofacitinib. At the American Academy of Dermatology meeting in March 2022, results of the ALLEGRO phase 2b/3 trial found that the JAK inhibitor ritlecitinib (50 mg or 20 mg daily, with or without a 200-mg loading dose), was efficacious in adults and adolescents with AA, compared with placebo, with no safety concerns noted. “This looks to be very, very promising,” she said, “and also very safe.” Two phase 3 trials of baricitinib also presented at the same meeting found it was superior to placebo for hair regrowth in adults with severe AA at 36 weeks. (On June 13, shortly after Dr. Hordinsky spoke at the meeting, the FDA approved baricitinib for treating AA in adults, making this the first systemic treatment to be approved for AA).

Research on topical JAK inhibitors for AA has been disappointing, Dr. Hordinsky said.

Alopecia areata and atopic dermatitis. For patients with both AA and AD, dupilumab may provide relief, she said. She referred to a recently published phase 2a trial in patients with AA (including some with both AA and AD), which found that Severity of Alopecia Tool (SALT) scores improved after 48 weeks of treatment, with higher response rates among those with baseline IgE levels of 200 IU/mL or higher. “If your patient has both, and their immunoglobulin-E level is greater than 200, then they may be a good candidate for dupilumab and both diseases may respond,” she said.

Scalp symptoms. It can be challenging when patients complain of itch, pain, or burning on the scalp, but have no obvious skin disease, Dr. Hordinsky said. Her tips: Some of these patients may be experiencing scalp symptoms secondary to a neuropathy; others may have mast cell degranulation, but for others, the basis of the symptoms may be unclear. Special nerve studies may be needed. For relief, a trial of antihistamines or topical or oral gabapentin may be needed, she said.

Frontal fibrosing alopecia (FFA). This condition, first described in postmenopausal women, is now reported in men and in younger women. While sunscreen has been suspected, there are no good data that have proven that link, she said. Cosmetics are also considered a possible culprit. For treatment, “the first thing we try to do is treat the inflammation,” Dr. Hordinsky said. Treatment options include topical high-potency corticosteroids, intralesional steroids, and topical nonsteroid anti-inflammatory creams (tier 1); hydroxychloroquine, low-dose antibiotics, and acitretin (tier 2); and cyclosporin and mycophenolate mofetil (tier 3).

In an observational study of mostly women with FFA, she noted, treatment with dutasteride was more effective than commonly used systemic treatments.

“Don’t forget to address the psychosocial needs of the hair loss patient,” Dr. Hordinsky advised. “Hair loss patients are very distressed, and you have to learn how to be fast and nimble and address those needs.” Working with a behavioral health specialist or therapist can help, she said.

She also recommended directing patients to appropriate organizations such as the National Alopecia Areata Foundation and the Scarring Alopecia Foundation, as well as conferences, such as the upcoming NAAF conference in Washington. “These organizations do give good information that should complement what you are doing.”

Medscape Live and this news organization are owned by the same parent company. Dr. Hordinsky reported no disclosures.

At the American Academy of Dermatology meeting in March 2022, results of the ALLEGRO phase 2b/3 trial found that the JAK inhibitor ritlecitinib (50 mg or 20 mg daily, with or without a 200-mg loading dose), was efficacious in adults and adolescents with AA, compared with placebo, with no safety concerns noted. “This looks to be very, very promising,” she said, “and also very safe.” Two phase 3 trials of baricitinib also presented at the same meeting found it was superior to placebo for hair regrowth in adults with severe AA at 36 weeks. (On June 13, shortly after Dr. Hordinsky spoke at the meeting, the FDA approved baricitinib for treating AA in adults, making this the first systemic treatment to be approved for AA).

Research on topical JAK inhibitors for AA has been disappointing, Dr. Hordinsky said.

Alopecia areata and atopic dermatitis. For patients with both AA and AD, dupilumab may provide relief, she said. She referred to a recently published phase 2a trial in patients with AA (including some with both AA and AD), which found that Severity of Alopecia Tool (SALT) scores improved after 48 weeks of treatment, with higher response rates among those with baseline IgE levels of 200 IU/mL or higher. “If your patient has both, and their immunoglobulin-E level is greater than 200, then they may be a good candidate for dupilumab and both diseases may respond,” she said.

Scalp symptoms. It can be challenging when patients complain of itch, pain, or burning on the scalp, but have no obvious skin disease, Dr. Hordinsky said. Her tips: Some of these patients may be experiencing scalp symptoms secondary to a neuropathy; others may have mast cell degranulation, but for others, the basis of the symptoms may be unclear. Special nerve studies may be needed. For relief, a trial of antihistamines or topical or oral gabapentin may be needed, she said.

Frontal fibrosing alopecia (FFA). This condition, first described in postmenopausal women, is now reported in men and in younger women. While sunscreen has been suspected, there are no good data that have proven that link, she said. Cosmetics are also considered a possible culprit. For treatment, “the first thing we try to do is treat the inflammation,” Dr. Hordinsky said. Treatment options include topical high-potency corticosteroids, intralesional steroids, and topical nonsteroid anti-inflammatory creams (tier 1); hydroxychloroquine, low-dose antibiotics, and acitretin (tier 2); and cyclosporin and mycophenolate mofetil (tier 3).

In an observational study of mostly women with FFA, she noted, treatment with dutasteride was more effective than commonly used systemic treatments.

“Don’t forget to address the psychosocial needs of the hair loss patient,” Dr. Hordinsky advised. “Hair loss patients are very distressed, and you have to learn how to be fast and nimble and address those needs.” Working with a behavioral health specialist or therapist can help, she said.

She also recommended directing patients to appropriate organizations such as the National Alopecia Areata Foundation and the Scarring Alopecia Foundation, as well as conferences, such as the upcoming NAAF conference in Washington. “These organizations do give good information that should complement what you are doing.”

“No matter who the patient is, whether a child, adolescent, or adult, the key to figuring out hair disease is getting a good history,” Maria Hordinsky, MD, professor and chair of the department of dermatology at the University of Minnesota, Minneapolis, said at the Medscape Live Women’s and Pediatric Dermatology Seminar.

During her presentation on what’s new in hair disorders, Dr. Hordinsky covered a range of disorders and treatments, with some common denominators, such as the need for a good history. She also urged physicians and other health care providers to use the electronic medical record and to be thorough in documenting information – noting nutrition, hair care habits, supplement use, and other details.

Lab tests should be selected based on that history, she said. For instance, low iron stores can be associated with hair shedding; and thyroid function studies might be needed.

Other highlights of her presentation included comments on different types of alopecia, and some new treatment approaches:

Androgenetic alopecia. In a meta-analysis and systematic review published in 2017, all treatments tested (2% and 5% minoxidil in men, 1 mg finasteride in men, 2% minoxidil in women, and low-level laser light therapy in men) were superior to placebo. Several photobiomodulation (PBM) devices (also known as low-level laser light) for home use have been cleared for androgenetic alopecia by the Food and Drug Administration; a clinician’s guide, published in 2018, provides information on these devices.

Hair and hormones. Combination therapy for female-pattern hair loss – low-dose minoxidil and spironolactone – is important to know about, she said, adding there are data from an observational pilot study supporting this treatment. Women should not become pregnant while on this treatment, Dr. Hordinsky cautioned.

PRP (platelet rich plasma). This treatment for hair loss can be costly, she cautioned, as it’s viewed as a cosmetic technique, “but it actually can work rather well.”

Hair regrowth measures. Traditionally, measures center on global assessment, the patient’s self-assessment, investigator assessment, and an independent photo review. Enter the dermatoscope. “We can now get pictures as a baseline. Patients can see, and also see the health of their scalp,” and if treatments make it look better or worse, she noted.

Alopecia areata (AA). Patients and families need to be made aware that this is an autoimmune disease that can recur, and if it does recur, the extent of hair loss is not predictable. According to Dr. Hordinsky, the most widely used tool to halt disease activity has been treatment with a corticosteroid (topical, intralesional, oral, or even intravenous corticosteroids).

Clinical trials and publications from 2018 to 2020 have triggered interest in off-label use and further studies of JAK inhibitors for treating AA, which include baricitinib, ruxolitinib, and tofacitinib.

The U.S. Food and Drug Administration approved baricitinib oral tablets on June 13 as the first systemic treatment for adult patients with severe alopecia areata.

The disorder with the hallmark signs of patchy baldness affects more than 300,000 people in the United States each year. In patients with the autoimmune disorder, the body attacks its own hair follicles and hair falls out, often in clumps. In February, the FDA granted priority review for baricitinib in adults with severe AA.

Baricitinib (Olumiant) is a Janus kinase (JAK) inhibitor, which blocks the activity of one or more enzymes, interfering with the pathway that leads to inflammation.

The FDA reports the most common side effects include upper respiratory tract infections, headache, acne, hyperlipidemia, increase of creatinine phosphokinase, urinary tract infection, elevated liver enzymes, inflammation of hair follicles, fatigue, lower respiratory tract infections, nausea, Candida infections, anemia, neutropenia, abdominal pain, herpes zoster (shingles), and weight gain. The labeling for baricitinib includes a boxed warning for serious infections, mortality, malignancy, major adverse cardiovascular events, and thrombosis.
 

Evidence from two trials led to announcement

The decision came after review of the results from two randomized, double-blind, placebo-controlled trials (BRAVE AA-1 and BRAVE AA-2) with patients who had at least 50% scalp hair loss as measured by the Severity of Alopecia Tool (SALT score) for more than 6 months.

Patients in these trials got either a placebo, 2 mg of baricitinib, or 4 mg of baricitinib every day. The primary endpoint for both trials was the proportion of patients who achieved at least 80% scalp hair coverage at week 36.

In BRAVE AA-1, 22% of the 184 patients who received 2 mg of baricitinib and 35% of the 281 patients who received 4 mg of baricitinib achieved at least 80% scalp hair coverage, compared with 5% of the 189 patients in the placebo group.

In BRAVE AA-2, 17% of the 156 patients who received 2 mg of baricitinib and 32% of the 234 patients who received 4 mg achieved at least 80% scalp hair coverage, compared with 3% of the 156 patients in the placebo group.

The results were reported at the annual meeting of the American Academy of Dermatology meeting in March.

Baricitinib was originally approved in 2018 as a treatment for adult patients with moderately to severely active rheumatoid arthritis who have had an inadequate response to one or more tumor necrosis factor (TNF)–blockers. It is also approved for treating COVID-19 in certain hospitalized adults. 

Two other companies, Pfizer and Concert Pharmaceuticals, have JAK inhibitors in late-stage development for AA. The drugs are already on the market for treating rheumatoid arthritis and other autoimmune diseases. FDA approval is important for insurance coverage of the drugs, which have a list price of nearly $2,500 a month, according to The New York Times.

Until now, the only treatments for moderate to severe AA approved by the FDA have been intralesional steroid injections, contact sensitization, and systemic immunosuppressants, but they have demonstrated limited efficacy, are inconvenient for patients to take, and have been unsuitable for use long term.

“Today’s approval will help fulfill a significant unmet need for patients with severe alopecia areata,” Kendall Marcus, MD, director of the Division of Dermatology and Dentistry in the FDA’s Center for Drug Evaluation and Research, said in the press release.

As Medscape reported last month, The European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) has recommended approval of baricitinib for adults with severe AA.

AA received widespread international attention earlier this year at the Academy Awards ceremony, when actor Will Smith walked from the audience up onto the stage and slapped comedian Chris Rock in the face after he directed a joke at Mr. Smith’s wife, Jada Pinkett Smith, about her shaved head. Mrs. Pinkett Smith has AA and has been public about her struggles with the disease.

Albendazole is a commonly prescribed anthelmintic that typically is well tolerated. Its broadest application is in developing countries that have a high rate of endemic nematode infection.^1,2 Albendazole belongs to the benzimidazole class of anthelmintic chemotherapeutic agents that function by inhibiting microtubule dynamics, resulting in cytotoxic antimitotic effects.³ Benzimidazoles (eg, albendazole, mebendazole) have a binding affinity for helminthic β-tubulin that is 25- to 400-times greater than their binding affinity for the mammalian counterpart.⁴ Consequently, benzimidazoles generally are afforded a very broad therapeutic index for helminthic infection.

A 53-year-old man presented to the emergency department (ED) after an episode of syncope and sudden hair loss. At presentation he had a fever (temperature, 103 °F [39.4 °C]), a heart rate of 120 bpm, and pancytopenia (white blood cell count, 0.4×10³/μL [reference range, 4.0–10.0×10³/μL]; hemoglobin, 7.0 g/dL [reference range, 11.2–15.7 g/dL]; platelet count, 100×10³/μL [reference range, 150–400×10³/μL]). A toxicology screen was positive for cocaine, opiates, and benzodiazepines. The blood alcohol concentration was 126 mg/dL.

The patient reported severe gastrointestinal (GI) distress and diarrhea for the last year as well as a 25-lb weight loss. He discussed his belief that his GI symptoms were due to a parasite he had acquired the year prior; however, he reported that an exhaustive outpatient GI workup had been negative. Two weeks before presentation to our ED, the patient presented to another ED with stomach upset and was given a dose of albendazole. Perceiving alleviation of his symptoms, he purchased 2 bottles of veterinary albendazole online and consumed 113,000 mg—approximately 300 times the standard dose of 400 mg.

A dermatologic examination in our ED demonstrated reticulated violaceous patches on the face and severe alopecia with preferential sparing of the occipital scalp (Figure 1). Photographs taken by the patient on his phone from a week prior to presentation showed no facial dyschromia or signs of hair loss. A punch biopsy of the chin demonstrated perivascular and perifollicular dermatitis with eosinophils, most consistent with a drug reaction.

The European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) has recommended approval of baricitinib, a Janus kinase (JAK) inhibitor, for the treatment of adults with severe alopecia areata (AA).

The development, which was announced in a May 20, 2022, press release from the manufacturer, Eli Lilly and Incyte, marks the first step toward European regulatory approval of baricitinib (Olumiant) for patients with severe AA, and it is now referred to the European Commission for final action. A decision is expected within the next 2 months.

The committee based its positive opinion on the results of the phase 3 BRAVE-AA1 and BRAVE-AA2 trials, recently published in the New England Journal of Medicine, which evaluated the efficacy and safety of baricitinib in 1,200 patients with severe AA, according to the press release. The primary endpoint was the proportion of patients achieving a Severity of Alopecia Tool (SALT) score of ≤20 at week 36. In both studies, 1 out of 3 patients treated with baricitinib 4-mg achieved 80% or more scalp hair coverage, compared with 1 out of 20 patients and 1 out of 50 patients taking placebo in BRAVE-AA1 and BRAVE-AA2, respectively (P ≤ .001 for all comparisons to placebo).

According to safety profile information from the phase 3 BRAVE-AA clinical program, few patients discontinued treatment because of adverse events (2.6% or less across both studies), and most treatment-emergent adverse events were mild or moderate in severity.

In February 2022, the Food and Drug Administration granted priority review for baricitinib in adults with severe AA. Lilly expects additional regulatory decisions in the United States and Japan in 2022.

In both studies, 1 out of 3 patients treated with baricitinib 4-mg achieved 80% or more scalp hair coverage, compared with 1 out of 20 patients and 1 out of 50 patients taking placebo in BRAVE-AA1 and BRAVE-AA2, respectively (P ≤ .001 for all comparisons to placebo).

According to safety profile information from the phase 3 BRAVE-AA clinical program, few patients discontinued treatment because of adverse events (2.6% or less across both studies), and most treatment-emergent adverse events were mild or moderate in severity.

In February 2022, the Food and Drug Administration granted priority review for baricitinib in adults with severe AA. Lilly expects additional regulatory decisions in the United States and Japan in 2022.

Baricitinib is approved in the United States as a treatment for adults with moderate to severe rheumatoid arthritis. Prescribing information can be viewed here.

To the Editor:

A 57-year-old man with hypertension, dyslipidemia, and congestive heart failure presented with a disfiguring eruption comprised of asymptomatic papules on the face that appeared 12 months post–heart transplantation. Immunosuppressive medications included mycophenolic acid and tacrolimus ointment (FK506). The pinpoint papules spread from the central face to the ears, arms, and legs. Physical examination revealed multiple 0.5- to 1-mm flesh-colored papules over the glabella, nose, nasolabial folds, philtrum, chin, ears, arms, and legs sparing the trunk. The initial appearance of the facial rash resembled the surface of a nutmeg grater with central white spiny excrescences overlying fine papules (spinulosism)(Figure 1). In addition, eyebrow alopecia was present.

A 3-mm punch biopsy of a papule with a central spine was performed on the left thigh. Microscopic examination revealed marked dilatation of anagen hair follicles with a proliferation of haphazard inner root sheath cells replacing the follicular lumen. Hair shafts were absent, and plugged infundibula were observed (Figure 2). The inner root sheath keratinocytes were enlarged and dystrophic with deeply eosinophilic trichohyalin granules (Figure 3). The epidermis, outer root sheath epithelium, and eccrine structures were unremarkable.

Transmission electron microscopy (TEM) confirmed the presence of intranuclear viral inclusions within affected inner root sheath keratinocytes composed of nonenveloped icosahedral viral particles measuring 33 to 38 nm in diameter (Figure 4). These findings morphologically were consistent with a polyomavirus. No intracytoplasmic or extracellular viral particles were identified. The clinical history, physical examination, histopathology, and electron microscopy features strongly supported the diagnosis of trichodysplasia spinulosa (TS) despite insufficient material being retrieved for polymerase chain reaction identification.

Trichodysplasia spinulosa was first described by Haycox et al¹ in 1999. The authors suggested a viral etiology. Eleven years later, TS-associated polyomavirus (TSPyV) was identified by van der Meijden et al.² Follicular keratinocytes are the specific target for TSPyV.³ Evidence has been presented suggesting that TS is caused by a primary infection or reactivation of TSPyV in the setting of immunosuppression.^4,5

Patients with TS present with papular eruptions that appear on the central face with spiny excrescences and various degrees of alopecia involving the eyebrows or eyelashes. Histopathologic features include distended hair follicles with expansion of inner root sheath cells, eosinophilic trichohyalin granules, and the absence of hair shafts. The viral protein can be verified through immunohistochemistry TSPyV VP1 staining that demonstrates co-localization with trichohyalin. Viral particles also can be visualized as 35- to 38-nm intranuclear particles with an organized crystalloid morphology on TEM.^6,7 The negative polymerase chain reaction in our patient could be the result of suboptimal template DNA concentration extracted from the limited amount of tissue remaining in the block after hematoxylin and eosin staining.

The clinical differential diagnosis of central facial spinulosism includes the follicular spicules of multiple myeloma (FSMM). In fact, FSMM and TS can only be differentiated after obtaining a blood profile and bone marrow biopsy that excludes the diagnosis of FSMM. A history of immunosuppression typically suggests TS. Histopathology often is equivocal in FSMM⁸; however, TEM reveals viral particles (TSPyV) in TS. Transmission electron microscopy in FSMM demonstrates fibrillary structures arranged in a paracrystalline configuration with unknown significance instead of viral particles. Despite the absence of viral particles on TEM, a low mean copy number of Merkel cell polyomavirus was isolated from a patient with FSMM who responded dramatically to treatment with topical cidofovir gel 1%.⁸ In addition to treating the underlying multiple myeloma in FSMM, topical cidofovir gel 1% also may have a role in treatment of these patients, suggesting a possible viral rather than simply paraneoplastic etiology of FSMM. Therefore, polyomavirus infection should be considered in the initial workup of any patient with fine facial follicular spicules.

The most effective management of TS in transplant recipients is to reduce immunosuppression to the lowest level possible without jeopardizing the transplanted organ.⁹ In our case, reduction of immunosuppressive drugs was not possible. In fact, immunosuppression in our patient was increased following evidence of early rejection of the heart transplant. Although manual extraction of the keratin spicules resulted in considerable improvement in a similar facial eruption in a patient with pediatric pre–B-cell acute lymphoblastic leukemia developing TS,¹⁰ it is impossible to apply this approach to patients such as ours who have thousands of tiny lesions. Fortunately, custom-compounded cidofovir gel 1% applied twice daily to the patient’s face and ears for 4 weeks led to near-complete clearance at follow-up (Figure 5). Due to the high cost of the medication (approaching $700 for one tube), our patient applied this medication to the face only several times weekly with excellent improvement. Thus, it appears that it is possible to suppress this virus with topical medication alone.

Polyomavirus infection should be considered in patients presenting with fine follicular spiny papules, especially those who are immunosuppressed. The possibility of coexisting multiple myeloma should be excluded.
