Abstract
Pemphigus vulgaris is a rare autoimmune blistering disease, involving the skin and mucous epithelia, which is characterized by flaccid blisters and erosions. It is caused by the presence of autoantibodies directed against desmoglein, a glycoprotein that plays a critical role in cell–cell attachment. Upon a predisposing genetic background, different agents have been shown to act as triggers for the pathogenesis of pemphigus. The most evident association is with drug intake, while the role of diet is often underestimated. The aim of this article is to review the possible role of tannins, a group of phenolic metabolites that are widely distributed in almost all plant foods and beverages, particularly red wine, as a trigger for pemphigus vulgaris.
