[The clinical usefulness of a new (the second generation) antibody to hepatitis C virus].

Le résumé fourni par la source

To clarify the clinical usefulness of a second generation antibody to hepatitis C virus (anti-HCV-2), we tested the anti-HCV-2 by enzyme immunosorbent assay (Imucheck HCV Ab) in comparison to the first generation antibody (anti-HCV-1). Serum samples were obtained from the patients with acute hepatitis, chronic liver diseases, alcoholic liver disease and autoimmune liver diseases. Furthermore, both antibodies were tested in serum samples from individuals in a hyperendemic area of non-A, non-B hepatitis. Anti-HCV-2 was detected earlier than anti-HCV-1 in acute type C hepatitis. The prevalence of anti-HCV-2 was higher than that of anti-HCV-1 in acute and chronic non-A, non-B liver diseases. However, prevalence of anti-HCV-2 was not increased in patients with non-viral liver disease such as pure alcoholic liver disease and autoimmune liver diseases. The HCV-infection rate was increased to about 40% by detection of anti-HCV-2 in individuals in hyperendemic area of non-A, non-B hepatitis. Thus, the assay of anti-HCV-2 is very useful to detect actual HCV infection. The accuracy and sensitivity of anti-HCV-2 were higher than those of anti-HCV-1.
