[Hepatitis beta-antigen titer and subtypes of acute and chronic hepatitis]
Abstract:
The incidence of the hepatitis B antigen (HBSAg) in the sera of 650 acute virus hepatitis (AVH) and 200 chronic hepatitis (CH) patients was determined by screening test (counter-immunoelectrophoresis and immunodiffusion). The findings showed a positivity in 28% of the acute virus hepatitis patients and in 47% of the chronic hepatitides. Further, the detected HB Ag was investigated both quantitatively (titer) and qualitatively (subtype). The results obtained have shown the absence of differences in the HB Ag-titer distribution of the two groups investigated and the prevalence of the HBSAg/ayw subdeterminant in both groups (62% in AVH and 57% in CH patients).
