Abstract
BACKGROUND: Pemphigus is a group of autoimmune blistering diseases of which the major forms are pemphigus foliaceus (PF) and vulgaris (PV). In Brazil, PF occurs in an endemic form also known as fogo selvagem. The main autoantibody in PF is against desmoglein 1 (DSG1), while in PV the main antibody is anti-desmoglein 3 (DSG3), but often anti-DSG1 is also present. The aim of the present study was to analyze the levels of anti-DSG1 and antiDSG3 autoantibodies in Brazilian PF and PV patients, considering different stages of the disease for PF patients and comparing these levels to those of healthy individuals living in and outside the endemic regions.
