The relationship between Helicobacter pylori IgG antibody and autologous serum test in chronic urticaria

Abstract

Background In chronic urticaria, suspicious factors are Helicobacter pylori (HP) infection and autoimmunity, as well as other etiologic agents. Autologous serum injection is the first step to identify autoimmune urticaria. Our study was performed to determine the prevalence of HP infection in patients with chronic urticaria, and to evaluate the results of autologous serum testing in chronic urticaria patients who had HP antibodies.
