We examined sequential serum samples from 12 patients with well-characterized posttransfusion non-A, non-B hepatitis who had an acute, resolving self-limited type of clinical course for the presence of antibody to the hepatitis C virus nucleocapsid (core) protein (p22) expressed by a recombinant bac

Abstract
Drug users and particularly, injecting drug users, are at increased risk for infection with hepatitis C virus (HCV). The aims of the study were to simultaneously detect HCV core antigen and specific antibodies in sera from Saudi drug users using the new HCV combination assay and to compare this data with HCV core antigen, antiβHCV antibodies and HCV RNA data from the same patients. A total of 297 patients who are followed up or admitted to a drug rehabilitation hospital over a period of 3 years were included in this study. Samples were analyzed using the new HCV Ag/Ab combination assay (Meurex), HCV core Ag assay, HCV antibodies and with the HCV RNA assay. Out of the 297 samples from Saudi drug users, 111 samples (37.4%) have detectable HCV core Ag, 112 samples (37.7%) have detectable HCV antibodies, 118 have detectable HCV RNA, and 116 samples were positive by the HCV Ag/Ab combination assay (39.1%). Out of the 116 samples, HCV core Ag was detected in 110 samples (94.8%), HCV antibodies were detected in 111 (95.7%) samples and HCV RNA was detected in 114 samples (98.3%). In the control group (nβ=β305), only 2 (0.66%) blood donor were positive by HCV antibodies assay, HCV RNA assay as well as HCV Ag/Ab combination assay. The new HCV Ag/Ab combination assay may well improve the overall quality of diagnosis of HCV infection especially in high risk population such as drug users that necessitates rigorous testing. J.

The significance of IgM and IgG class antibodies to hepatitis B virus (HBV) core component (anti-HBc) was investigated in a study of maternal-fetal HBV transmission. An IgM anti-HBc response was lacking in the majority (49/53) of HBV-infected infants. This antibody thus cannot be used as an indicato
Hemodialysis patients are recognized as a group at high risk of infection with hepatitis C virus (HCV). Therefore, such a population should be screened routinely for the presence of HCV viremia.
