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.
