The clinical utility of a new JCC‐2 enzyme‐linked immunosorbent assay kit that detects and quantitates anti‐hepatitis C virus (anti‐HCV) core antibodies (anti‐HCc) was investigated. Serum samples were obtained from 102 patients with various non‐A, non‐B liver diseases, including 19 cases of chronic hepatitis type C who had been treated with interferon (IFN). The results of the anti‐JCC‐2 assay were significantly correlated with serum HCV‐RNA positivity. Patients who were HCV‐RNA positive exhibited a high rate of positivity for anti‐JCC‐2 (72.2% in acute hepatitis, > 90% in chronic liver diseases). The geometric mean of the anti‐JCC‐2 titre was not significantly different among different stages of chronic liver disease (among CPH, CAH and LC). The anti‐JCC‐2 titre decreased gradually in cases that became HCV‐RNA negative after IFN therapy. If HCV‐RNA positivity recurred, the anti‐JCC‐2 titre increased, indicating that serial measurements of the anti‐JCC‐2 titre are useful for monitoring the antiviral effect of IFN treatment. These results suggest that quantification of anti‐HCc by the anti‐JCC‐2 assay is superior to the semi‐quantification of circulating HCV‐RNA provided by monitoring of IFN therapy. Monitoring of HCV‐RNA status using reverse transcription‐nested polymerase chain reaction (RT‐nested PCR) is possible, but it is technically demanding and too expensive for routine clinical use.
