Combination of total glucosides of paeony, narrow‐band ultraviolet B, and oral corticosteroid mini‐pulse therapy for nonsegmental vitiligo: A retrospective study

Abstract

BackgroundThe total glucoside of paeony (TGP) is recognized for its immunomodulatory properties and anti‐inflammatory effects. This study evaluates the efficacy of TGP combined with oral mini‐pulse therapy (OMP) and narrow‐band ultraviolet B (NB‐UVB) in treating active nonsegmental vitiligo (NSV).Materials and methodsThe combination therapy was contrasted against those from a group treated solely with OMP and NB‐UVB. Data from 62 patients undergoing TGP combination treatment and 55 without were analyzed over a 3‐month period. After 6 months, the differences in recurrence rate were investigated by follow‐up.ResultsThe findings indicate that integrating TGP may yield superior outcomes compared to OMP + NB‐UVB alone. Moreover, the patient's oxidative stress makers were significantly reduced after the treatment. The majority of patients in the TGP cohort exhibited enhanced skin pigmentation over the duration. Notably, no increase in side effects or recurrence was observed in this group. Especially, patients with vitiligo on their head and neck experienced pronounced improvements.ConclusionThe efficacy of the combination treatment group was better than that of the control group at 2 and 3 months, and there was no difference in recurrence rate and side effects, suggesting that TGP may continue to show efficacy in NSV for a longer period of time by reducing the level of oxidative stress, and is especially suitable for patients with head and neck lesions.
