The presence and levels of hepatitis C virus (HCV) RNA and immunoglobulin M (IgM) and IgG antibodies against the virus core protein were determined in 449 serum specimens. Despite the fact that a relationship between the presence, but not the levels, of HCV RNA and HCV IgM was observed, the significance of HCV core IgM assays seems limited Patients with undetectable plasma HCV RNA after the six-month follow-up were classified as sustained responders (SR), patients who cleared the virus from their serum but with HCV RNA reappearance during follow-up were classified as relapse responders (RR). Results: Twenty six percent of the SVR patients had detectable level of HCV RNA in PBMC Hepatitis C virus (HCV) possesses a single-stranded, positive-sense RNA that is 9.4 kb in length. The complete HCV genome has been cloned and sequenced and encodes for a nucleocapsid, an envelope, and five nonstructural proteins (1,2). The 5' untranslated region of the virus is highly conserved among the HCV genotypes that have been identified to date (3-5) and has been selected by most investigators as the site for developing oligonucleotide primers and probes for the polymerase chain.

  1. BACKGROUND: Routine analysis of serum and/or plasma specimens for hepatitis C virus (HCV) RNA does not always correctly reflect the response to antiviral therapy. Analysis of whole-blood specimens for detection of viral RNA should provide more-accurate prognostic information. METHODS: Whole-blood, serum, and plasma specimens (268 sample sets) were obtained from 56 patients who did not respond to initial interferon (IFN)- alpha 2b monotherapy (5 MU every 2 days for 3 months.
  2. The HCV core protein is a highly basic, RNA-binding protein that forms the viral capsid. The E1 and E2 envelope glycoproteins are necessary for viral entry and fusion. Non-structural proteins include NS2, NS3, NS4A and 4B, and NS5A and 5B. The NS2-NS3 complex functions as a protease, and NS3 also has a helicase/NTPase domain
  3. ate results with this assay will be automatically evaluated with the subsequent test HCVGR / Hepatitis C Virus Genotype Resolution, Serum. An HCV genotype result of 1 without a subtype result may be due to 1 or more of the following causes: 1) low HCV RNA level (ie, <500 IU/mL), 2) probe reactivity with multiple genotype 1 subtypes, 3) variation in HCV genotype 1 target sequence, or 4) misclassification of some true genotype 6 strains
