A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

Anti-hepatitis C virus (HCV) therapy allows complete recovery of HCV infection (sustained virologic response). Reduction of necro-inflammation results usually in a stabilization then in a reduction of fibrosis and even of cirrhosis at least in patients with sustained virologic response. The randomised controlled RIBAVIC ANRS HC02 trial comparing the combination ribavirin-pegylated interferon-alpha2b versus ribavirine-standard interferon-alpha2b as first treatment in HIV-HCV co-infected patients allowed an analysis of 205 paired (pre- and post-treatment) biopsies using the Metavir and Ishak scores. A significant reduction was associated with sustained virologic response and non response with stabilization. There was no positive impact on fibrosis despite sustained virologic response and a deterioration in non responders. In multivariate analysis, didanosine and non response were significantly associated with fibrosis deterioration. The absence of fibrosis reversal in co-infected patients is related to virologic non response and probably to co-factors of fibrosis worsening, like the mitochondrial toxicity of antiretrovirals and especially of didanosine. In the RIBAVIC cohort (prospective followup of 383 co-infected HIV-HCV treated patients) with a median of 60 months, 21 patients (5 %) had a liver event: all were non responders and 20 had fibrosis score > or = F3. In multivariate analysis, factors associated with survival were virologic response to antiviral therapy, fibrosis score 350/mL. These results emphasize the need of early therapeutic interventions to increase the rate of sustained virologic response and to decrease the rate of liver complications in the most severe patients.
