A prospective study to compare the efficacy of cryotherapy versus intralesional steroid in alopecia areata

Abstract

Background: Alopecia areata (AA) is an autoimmune disease that results in the loss of hair on the scalp and elsewhere on the body. The present study was conducted to compare the intralesional steroid and cryotherapy in the treatment of AA. Materials and Methods: The present clinical study was conducted in the Department of Dermatology, Venereology, and Leprology, Muzaffarnagar Medical College. The simple random sampling technique was used for randomly dividing the subjects into two groups: group I (local cryotherapy) and group II (intralesional corticosteroid). Results: A positive response was significantly more among the intralesional steroid group (86.0%) when compared with the cryotherapy group (62.0%). There was a significant difference in relapse between intralesional steroid group (22.0%) and cryotherapy group (16.0%). An excellent response was significantly more among the intralesional steroid group (44.0%) when compared with the cryotherapy group (18.0%). Poor response was significantly more among the cryotherapy group (18.0%), compared with the intralesional steroid group (0.0%). The mean pre-treatment, post-treatment, and the change from pre- to post-treatment Severity of Alopecia Tool [SALT] were compared between cryotherapy and intralesional steroid groups using the unpaired t -test. The mean pre-treatment, post-treatment, and the change from pre- to post-treatment SALT were significantly more among the intralesional steroid group when compared with the cryotherapy group. Conclusion: The authors found that superficial cryotherapy could be a meaningful adjuvant treatment option for AA patients. There was a significantly less relapse rate with cryotherapy. Among the currently available topical modalities for the treatment of AA, the best response was to the intralesional steroids followed by cryotherapy.
