Serum pregnancy‐associated α2‐glycoprotein levels in the evolution of Hepatitis B virus infection

Abstract

Serum pregnancy-associated alpha 2-glycoprotein (alpha 2-PAG) levels were evaluated in a follow-up study of patients with hepatitis B virus (HBV) infection and compared with biochemical and virological parameters. In a study of 25 patients with acute hepatitis, an association was found between high alpha 2-PAG values, ALT levels, and HBsAg in 20 patients (80%) (P less than 0.05), 18 recovered completely, and 2 had a protracted course. In five patients serum alpha 2-PAG levels were similar to those in the control group. On the other hand, eight (100%) chronic persistent HBV patients showed high levels of alpha 2-PAG (P less than 0.05) during the study period, and these levels correlated well with inflammatory activity and failure of HBsAg elimination. There were no significant differences in alpha 2-PAG values between asymptomatic HBsAg carriers and controls. Serial analysis of alpha 2-PAG, in correlation with viral markers, biochemical parameters, and histological data, would contribute to the ability to predict the final outcome of HBV infection.
