[Chronic glomerulonephritis with Hb antigen].

The authors report nine cases of chronic glomerulonephritis with positive hepatitis B antigen (AgHB) (8 cases) and positive anti-AgHb (1 case). Five patients had membranous glomerulonephritis. The sub-type was ad in 6 cases and ay in 2. In 3 members of two families of patients, AgHB was positive with the same sub-type as the subject studied. In 5 cases, liver biopsy showed signs of chronic hepatitis. According to the authors, a positive AgHB in glomerulonephritis is often associated with clinically latent chronic hepatitis.
