title: The efficacy of nicotinamide gel 4% as an adjuvant therapy in the treatment of cutaneous erosions of pemphigus vulgaris.
abstract: The high rate of morbidity and mortality resulting from long-term use of corticosteroids in pemphigus vulgaris (PV) warrants discovery of a new treatment strategy. Based on the pathophysiology of PV, nicotinamide can block the process of blister formation through its anti-inflammatory properties. This study was conducted to evaluate the clinical effectiveness of nicotinamide gel in the treatment of skin lesions of PV. In a double-blind, placebo-controlled study, eight PV patients with a total of 60 skin lesions were treated by either nicotinamide or placebo gel. After 30 days of treatment, epithelialization index of the two groups was compared. The mean of the epithelialization index in skin lesions that received nicotinamide was significantly higher than that of the placebo group (26 vs. -5.8, p < 0.001). Our results were suggestive that nicotinamide gel can effectively be used as an adjunctive treatment for PV lesions.
