Comparative evaluation of the efficacy of topical tacrolimus 0.03% and topical calcipotriol 0.005% mixed with betamethasone dipropionate versus topical clobetasol 0.05% in treatment of alopecia areata: A clinical and trichoscopic study.

BACKGROUND: Alopecia areata (AA) is a common non-scarring hair loss disorder that affects children and adults with a great psychological burden because of its recurrent and sometimes treatment-refractory nature. OBJECTIVE: To compare the efficacy of topical calcineurin inhibitor, topical potent steroid combined with vitamin D analogue versus topical superpotent steroid in treatment of localized AA. PATIENTS AND METHODS: Sixty subjects with chronic (>1 year) localized (SALT score < 25%) AA, confirmed clinically and dermoscopically, were randomized into three groups. Group I used topical 0.03% tacrolimus (Tarolimus®), group II used topical potent steroid combined with vitamin D analogue (Daivobet®). and group III used topical superpotent steroid (Dermovate®). All patients continued a daily therapy for three successive months and were followed up for three other months. Assessment was done using PULL test, SALT score, and dermoscopic comparison before and after therapy. RESULTS: Group II showed comparable statistical results to group III with lower values in a non-statistically significant way. Group I achieved the least improvement among all groups. CONCLUSION: Combined vitamin D analogues with potent steroid appears to be a more convenient treatment for localized AA than superpotent steroids because of less side effects and comparable efficacy. Tacrolimus needs further research or formula customization to be used as a topical therapy for AA.
