Abstract

Background: Alopecia areata (AA) is a chronic autoimmune disorder. Finding the best treatment regimen for it remains a challenge. Currently, one of the best documented treatment modalities for AA is topical immunotherapy. Aim: To evaluate the safety and efficacy of combined DPCP and anthralin versus standard protocol (DPCP alone). Methods: A prospective randomized clinical trial was conducted on 50 patients with Alopecia areata who received DPCP alone (group D) or in combination with anthralin (group D/A). Percentage of hair regrowth after 6 months of treatment and the incidence of drug-related adverse effects were evaluated and compared between the two groups. Results: Complete hair regrowth was observed among three patients in each group (18.75% in Group D and 15.79% in Group D/A) after 6 months. Moreover, 25% and 31% of patients in group D and 21% and 47% of patients in group D/A had > 75% and > 50% hair regrowth respectively at the end of the study (P-value: 0.696). In addition, earlier age of onset, chronicity of lesions, nail involvement, facial hair loss and extensive lesions at baseline were associated with poor clinical outcome. Conclusion: DPCP and anthralin was as effective as DPCP alone and anthralin did not add to the effect of DPCP in treating AA. © 2021 Elsevier B.V.
