title: Albumin receptors on HBsAG particles and subsequent sero-conversion designate HBeAG-positive patients among chronic active liver disease patients.
abstract: An enzyme-linked immunosorbent assay (ELISA) for the purpose of detecting the albumin receptor on hepatitis B virus surface antigen (HBsAg) particles was developed. Patient sera with moderate to high receptor values demonstrated significant correlations with serum DNA-polymerase activity (p less than 0.005), but not with HBeAg titer. Within one year of the study of 47 HBeAg-positive patients, only in the group of 12 patients with the moderately high values and 9 with low values, did 2 (16.7%) and 6 cases (66.7%) sero-convert, respectively. These results suggest that the albumin receptor might be a useful marker of HBsAg-positive patients.
