[Hepatitis B and hepatitis A markers in 33 cases of acute hepatitis B surface antigen-negative, hepatitis A virus antibody-positive viral hepatitis. Importance of immune complexes].
The authors have looked for the markers of HBV by R.I.A. method (HBsAg, anti HBsAg, HBeAg, anti HBeAg, anti HBcAg), of HAV (by measurement on two samples of HAVab or by measurement of HAVab IgM), the immune-complexes (I.C.C.) by C1q solid-phase binding assay method with E.L.I.S.A. with determination after division I.C.C. of HBsAg by R.I.A. method in 33 cases of HBsAg negative acute viral hepatitis. The 9% (3 cases) were HAV acute hepatitis, the 42,4% (14 cases) no A no B acute hepatitis, the 36,3% (12 case) were HBV acute hepatitis, in 9 anti HBcAg positive cases the I.C.C. with HBsAg positive after division resulted positive, the 12,3% (4 cases) had a positivity for HAVab by stereoconversion (2 cases) or HAVab IgM (2 cases) with HBsAg positivity after division I.C.C. This result puts a nosologic problem about the 4 cases of acute viral hepatitis, which, from epidemiological and clinical point of the view are HAV acute hepatitis.
