[Evaluation of hepatitis B virus markers for surrogate testing of hepatitis C].
To evaluate the surrogate markers of non-A, non-B hepatitis virus (es) carriage state, the relationship between antibody to hepatitis C virus (HCV) and antibody to HBc/HBs and liver enzyme (ALT) was sought in Saitama prefecture. Out of 36,642 blood donor samples, 410 (1.1%) samples were positive for anti-HCV. Anti-HCV was found in 1.79% of donors with anti-HBs and/or anti-HBc, which is 1.7 fold of the frequency found in donors (1.04%) negative for anti-HBc/HBs. In contrast to the reports from Europe or USA, a poor correlation of anti-HCV with the serological history of hepatitis B infection was observed. These results indicate that hepatitis B and hepatitis C were transmitted independently in the Japanese, which is more homogeneous socioeconomically than the European or American populations. On the other hand, anti-HCV prevalence was in close correlation to ALT level as observed in the USA and in Europe. As we predicted previously, ALT can be expected to reduce the incidence of post-transfusion non-A, non-B hepatitis, however, anti-HBc can not.
