OBJECTIVE: To preliminarily assess the efficacy and safety of the topical application of Epigallocatechin-3-gallate (EGCG) in treating vitiligo, a 6-month clinical trial was carried out.
METHOD: Patients were randomly given topical application of EGCG on the assigned lesions, with pimecrolimus being used as the control for twice a day over a 6-month treatment period. Responses to treatment were assessed based on the changes in VASI score for percentage reduction in body surface area and the PGA scores.
RESULTS: According to our results, both drugs were discovered to be markedly effective on repigmentation. The VASI of lesion had diminished from 1.19 ± 0.42 to 0.63 ± 0.38, in the EGCG-treated lesions, while from 1.18 ± 0.43 to 0.61 ± 0.36 in the pimecrolimus-treated lesions, and there was no statistically significant difference in VASI score between the EGCG-treated lesions and pimecrolimus-treated lesions (P = 0.755). Meanwhile, the mean PGA score on the EGCG applied side was 4.39 ± 2.23, while that was 4.43 ± 2.02 on the pimecrolimus applied side (P = 0.886). Furthermore, difference in the improvement degree between pimecrolimus side and EGCG side was not statistically significant (P = 0.845). Notably, no serious side effects were observed throughout the study.
CONCLUSION: Findings of the study indicate that topical EGCG can be effective on treating vitiligo.
