[Study on the immunoglobulin class of the antibody anti-e in acute HBsAg+ hepatitis and in asymptomatic carriers of HBsAg (author's transl)].

The AA. have determined the immunoglobulinic appartenence class of HBeAb in patients with acute hepatitis HBsAg+ and in asymptomatic carriers of HBsAg. In these the HBeAb belongs constantly to the IgG class, while in acute hepatitis patients this antibody results present in the IgM and IgG fractions of the sera. Especially, in patients with acute hepatitis the presence of HBeAb was observed only in some sera obtained during the tardive phase of disease.
