Efficacy of Individualized Homeopathic Medicines in the Treatment of Atopic Dermatitis in Adults: A Double-Blind, Randomized, Placebo-Controlled, Preliminary Trial.

Introduction: Individualized homeopathy (IH) in atopic dermatitis (AD) remained under-researched.

Objective: We aimed at evaluating efficacy of IH in AD.

Methods: A double-blind, randomized, placebo-controlled, short-term, preliminary trial was conducted in an Indian homeopathy hospital. Patients were randomized to either IH (n = 30) or identical-looking placebo (n = 30) using computerized randomization and allocation. Outcomes were patient-oriented scoring of AD (PO-SCORAD; primary end point), Dermatological Life Quality Index (DLQI) score, and AD burden score for adults (ADBSA; secondary end points), measured monthly for 3 months. An intention-to-treat sample was analyzed after adjusting baseline differences.

Results: On PO-SCORAD, improvement was higher in IH against placebo, but nonsignificant statistically (pmonth 1 = 0.433, pmonth 2 = 0.442, pmonth 3 = 0.229). Secondary outcomes were also nonsignificant - both DLQI and ADBSA (p > 0.05). Four adverse events (diarrhea, injury, common cold) were recorded.

Conclusions: There was a small, but nonsignificant direction of effect towards homeopathy, which renders the trial inconclusive. A properly powered robust trial is indicated.
