Frequency of seropositivity against infectious agents amongst pemphigus vulgaris patients: a case–control study on Strongyloides stercoralis, Helicobacter pylori, Toxoplasma gondii, Leishmania major, and Epstein–Barr virus

Environmental and genetic factors may contribute to the pathogenesis of pemphigus vulgaris (PV) as an autoimmune disease. We aimed to determine rates of seropositivity for immunoglobulin G (IgG) antibodies against a number of infectious agents in untreated and treated PV patients and in healthy individuals.Eighty-two newly diagnosed untreated PV patients (34 men and 48 women; mean ± standard deviation [SD] age: 44.18 ± 14.43 years) and 36...
