Determination of hepatitis B phenotype using biochemical and serological markers.

ABSTRACT: The aim of this study was to assess the validity of categorization of chronic hepatitis B viral infection into stages or phases based upon measures of disease activity and viral load, assuming these phenotypes will be useful for prognostication and determining the need for antiviral therapy. We assessed the phenotype of hepatitis B of 1,390 adult participants enrolled in the Hepatitis B Research Network Cohort Study, using a computer algorithm. Only 4% were immune tolerant, while 35% had chronic hepatitis B (18% e antigen positive and 17% e antigen negative) while 23% were inactive carriers. Strikingly, 38% of participants did not fit clearly into any one of these groups and were considered indeterminant. The largest subset of indeterminants had elevated serum aminotransferases with low le
