| pubmed-article:10718941 | pubmed:abstractText | We prospectively examined whether the complexity of hepatitis C virus (HCV) quasispecies is related to the response to interferon (IFN) therapy. Among 64 patients who had histologically proven chronic hepatitis and were treated with natural IFN-alpha, 53 patients were analysed. The other 11 patients discontinued therapy because of adverse effects of IFN. The complexity of the hypervariable region 1 (HVR 1) in quasispecies was determined using both clone number determined by fluorescence single-strand conformation polymorphism (SSCP) and nucleotide diversity determined by direct sequencing. These parameters were measured not only before treatment but also at completion and 6 months after therapy, if serum HCV RNA was detectable. This population of patients was different from the general Japanese population with regard to the high prevalence of patients infected with genotype 2a or 2b (49%), who had a higher viral load than those with genotype 1b (P = 0.021). Twenty-two patients (41.5%) were sustained responders. Genotype non-1b (P = 0.0009) and a smaller clone number (P = 0.008) were significantly associated with a sustained response. In multivariate analysis, these variables were independently associated with a sustained response (i.e. genotype: odds ratio 6.84, 95% CI 1.84-30. 12; and clone number: odds ratio 1.26, 95% CI 0.99-1.68). The clone number and nucleotide diversity did not change significantly between pretreatment and at completion or 6 months after therapy. These results suggest that lower complexity of HVR 1 quasispecies predicts a preferable response to IFN therapy that is independent of viral load, especially in the population of the relatively high prevalence of patients infected with genotype 2. | lld:pubmed |
