    Hepatitis C virus (HCV) is the chief aetiologic agent for the parenterally transmitted Non-A, Non-B (NANB) hepatitis. This preliminary study was done to determine the prevalence of anti-HCV in the blood donor population. Blood from 3,540 donors who donated blood to the Blood Services Centre, Hospital, Kuala Lumpur, from 25th August 1991 to 13th January 1992, was tested for anti-HCV using both the Ortho and Abbott 2nd Generation ELISA test kits. ELISA positive specimens were repeated twice but no confirmatory test was done. There were 53 out of 3,540 (1.49%) blood donors who were repeatedly reactive to anti-HCV by ELISA. We plan to do further tests to confirm the results, using RIBA-2 or Abbott Neutralising test. Twenty eight out of 1,713 (1.63%) Malays, 22 out of 1,373 (1.60%) Chinese and 2 out of 393 (0.50%) Indians had antibodies to HCV. There was no significant difference in prevalence in the different age groups. The majority of donors tested were males (3,511 out of 3,540) of which 53 (1.50%) were anti-HCV positive. Only 29 females were tested and all were negative. To determine infectivity of the anti-HCV positive cases we would like to introduce testing for RNA by polymerate chain reaction (PCR). Screening all donated blood for anti-HCV will decrease, but not totally eliminate, post-transfusion hepatitis.

  2. Fulltext Detection of virus-specific polymeric immunoglobulin A in acute hepatitis A, C, E virus serum samples using novel chimeric secretory component

    OBJECTIVE: To conduct a proof-of-concept study on preferential binding of polymeric IgA (pIgA) using a novel recombinant rabbit/human chimeric secretory component (cSC) and preliminary assessment of the diagnostic potential of virus-specific pIgA in discriminating acute hepatitis A, E, and C (HAV, HEV, HCV) patients and uninfected controls using an indirect enzyme-linked immunoassay.

    RESULTS: cSC binds > 0.06 μg/ml of purified human and mouse pIgA with negligible cross-reactivity against IgM and IgA. Virus-specific pIgA was significantly higher in serum of acute HAV (n = 6) and HEV (n = 12) patients than uninfected samples (HEV: p

    Sera from 80 Malaysians with confirmed hepatocellular carcinoma were tested for five markers of the hepatitis B virus, anti-HCV and anti-HDV by enzyme immunoassay, and alpha fetoprotein (AFP) was measured by radioimmunoassay. Of the patients, 98.8% had evidence of HBV infection and 75% were positive for HBsAg--which latter correlated with AFP raised above cut-off values of 500 ng/ml (P = 0.0001) and 200 ng/ml (P = 0.005). Males correlated significantly with the presence of HBsAg (P = 0.002). Thirty-one per cent of HBsAg positive patients were also positive for HBeAg and 74% for anti-HBe. Twenty per cent of the cases were concurrently positive for both HBsAg and anti-HBs. Six of 70 (8.6%) patients were positive for anti-HCV, of whom four were also positive for HBsAg. None of 67 patients tested for anti-HDV were positive. The results strongly indicate an important aetiological role for hepatitis B virus in causation of hepatocellular carcinoma among Malaysians.
