BackgroundAltered levels of sex hormones have been observed in many autoimmune disorders, but there is no considerable data about pemphigus. The aim of this study is to compare serum total and free prolactin and dehydroepiandrosterone sulfate (DHEAS) levels between patients with pemphigus and healthy controls and to determine the correlation of these hormones with disease severity.MethodsThis study included 52 newly diagnosed cases of pemphigus and 57 healthy controls. Serum prolactin (total and free) and DHEAS were measured in all subjects. Data analyses were performed using JMP, Version 7.ResultsPemphigus patients had significantly higher levels of total and free serum prolactin (both P = 0.01) and lower levels of DHEAS (P = 0.005) than healthy controls. A significant association was found between severity of pemphigus and total prolactin levels (r = 0.40, P = 0.003).ConclusionsThe patients with pemphigus had higher total and free prolactin and lower DHEAS concentrations, and patients with more severe disease had higher levels of serum total prolactin. These new data may suggest a potential role for sex hormones in the pathogenesis of pemphigus disease and provide new insights for the better management of this chronic and life-threatening disease.
