Defining the possibilities: is short duration treatment of chronic hepatitis C genotype 1 with sofosbuvir-containing regimens likely to be as effective as current regimens?

摘要

This review summarizes published data on sofosbuvir-based regimens for patients infected with HCV GT1 with a focus on evaluating the optimal and possible durations of treatment. Methods: PubMed and conference abstract books published between 2011-2015 were searched. Results: HCV treatment has decreased from 24 week regimens to studies done as short as 4 weeks. History of prior treatment or cirrhosis have consistently shown lower SVR12 rates with shorter duration therapies. Low cure rates have been seen in patients within 4 week trials, however, select patients with low fibrosis scores, low HCV VL and HCV GT-1b have moderate cure rates. Conclusion: Most patients will require 12-24 weeks of therapy. Further studies are needed to elucidate the predictors of treatment response to short duration therapies and optimal combination of DAAs.
