Early virologic responses and hematologic safety of direct-acting antiviral therapies in veterans with chronic hepatitis C.

Background & Aims: There are limited data on the early effectiveness of direct-acting antiviral (DAA) therapies for patients with hepatitis C virus (HCV) infection in routine medical practice. We aimed to evaluate real-world experience with DAA-based regimens.

Methods: By using the Veterans Affairs' Clinical Case Registry, we conducted a prospective observational intent-to-treat analysis of veterans infected with HCV genotype 1 who began treatment with pegylated interferon, ribavirin, and boceprevir (BOC, n = 661) or telaprevir (TVR, n = 198) before January 2012.

Assessment and utilization of rapid virologic response in US veterans with chronic hepatitis C: evaluating provider adherence to practice guidelines.

Background And Goals: There are limited data on the extent to which medical providers adhere to practice guidelines for the antiviral treatment of patients with chronic hepatitis C virus (HCV) infection. As representative of overall provider adherence to practice guidelines, provider adherence to specific recommendations regarding rapid virologic response (RVR) was assessed.

Study: From the Department of Veterans Affairs' Clinical Case Registry, all patients with HCV genotype 1 who initiated peginterferon and ribavirin between January 1, 2007 and December 31, 2008 were identified.
