title: Treatment of acute HCV infection in HIV-positive patients: experience from a multicentre European cohort.
abstract: BACKGROUND
  Early treatment of acute HCV infection has been shown to improve virological response rates in HIV-positive patients; however, details on when and how to best treat acute HCV infection remain unclear at present.
  
  
  METHODS
  In this European multicentre cohort study, HIV-positive patients with acute HCV infection were offered immediate or delayed anti-HCV therapy, pegylated interferon or pegylated interferon plus ribavirin combination therapy for 24 or 48 weeks, depending on the local protocol. The main outcome measure was the rate of sustained virological response (SVR).
  
  
  RESULTS
  A total of 150 HIV-infected men with acute HCV were enrolled between 2001 and 2006, 111 of whom received anti-HCV therapy. The predominant HCV genotype was type 1 and was present in 71 (64%) patients. Patients were treated with pegylated interferon (n=14) or pegylated interferon plus ribavirin (n=97), with a median duration of treatment of 25 weeks. SVR was obtained in 62% (95% confidence interval 52-71) of patients. There was no difference in SVR by genotype, CD4(+) T-cell count, HIV RNA, HCV RNA, alanine aminotransferase levels or use of ribavirin. Negative HCV RNA at weeks 4 and 12 were strong predictors of SVR.
  
  
  CONCLUSIONS
  High rates of SVR (62%) were obtained in HIV-coinfected patients with acute HCV infection undergoing early anti-HCV treatment using pegylated interferon alone or in combination with ribavirin. Treatment response at weeks 4 and 12 might be of help to further guide treatment duration. Urgent prospective studies are needed to further determine the optimal treatment regimen and the duration of therapy.
