title: A review of current anti-HCV treatment regimens and possible future strategies.
abstract: BACKGROUND
  Hepatitis C virus (HCV) infection remains a serious health problem worldwide. The current standard treatment of HCV infection is pegylated interferon-alpha plus ribavirin, but this is clearly not sufficiently effective and tolerable.
  
  
  OBJECTIVE
  To review current HCV treatment strategies and future options.
  
  
  METHODS
  Review of major clinical trials or observational studies when no trial is available.
  
  
  CONCLUSIONS
  Rates of sustained virologic response are widely variable, approximately 40-80%, depending on genotype, and even lower when HIV coinfection occurs. New agents, like small molecules that specifically target the HCV life cycle, may improve response rates; but safety is a concern.
