Evaluation of the Efficacy and Safety of Oral Tofacitinib for the Treatment of Alopecia Areata in Children

Alopecia areata (AA) is a common chronic relapsing nonscarring alopecia. Severe forms of AA commonly manifest during childhood. Treatment of AA is challenging due to the variability of the disease course as well as unpredictable responses to treatment. There is no uniform approved treatment for cure or sustained remission in children till now. Tofacitinib emerged as a novel drug in the treatment of AA, but few studies have been conducted on its safety and efficacy in children. Limitation of this study includes retrospective nature, small sample size, and lack of prolonged follow-up. Aim. This retrospective study aimed to assess the efficacy and safety of oral tofacitinib in children with AA. Method. In this retrospective study, we included patients aged 18 years or younger with AA. The scalp blandness of included patients was greater than 20% and they were on oral tofacitinib for at least two months. The demographic data, clinical characteristics, tofacitinib efficacy, and adverse effects were recorded. The primary endpoint was the last recorded percent change in the Severity of Alopecia Tool (SALT) score during treatment. Results. We included 26 patients (12 males and 14 females) with AA with a mean age of 11.6 ± 4.42 (3–18) years. Eighteen of them were in the alopecia areata (AA) group, whereas eight patients had alopecia totalis (AT) or alopecia universalis (AU). The mean disease duration before starting treatment with tofacitinib was 3.9 ± 3.3 years. Most of the patients were on a tofacitinib daily dose of 5 mg (53.85%) and 10 mg (38.46%). Patients were on tofacitinib for 6.73 ± 3.79 months. The patients’ baseline SALT score was recorded as 68.58 ± 32.65 and the final SALT score was 17.65 ± 23.88. Thus, the patients achieved a 50.92% reduction in the SALT score. Interestingly, there were no statistically significant differences in clinical efficacy between subtypes of AA and AT/AU. Conclusion. Tofacitinib was significantly effective in treating AA and AT/AU in children, with mild tolerable adverse effects, although relapse during treatment and tapering was recorded. Future randomized clinical trials with longer follow-up periods are needed to evaluate the safety of oral tofacitinib in children.
