Brief Summary

The aim of this study is to characterize neutrophil function in patients undergoing chronic hepatitis C triple therapy with protease inhibitors in comparison to dual therapy with peginterferon and ribavirin and with interferon free treatment regimen to thereby elucidate the possible mechanisms of protease-inhibitor associated infections.

Detailed Description

Chronic hepatitis C infection (CHC) is a major health problem, potentially leading to liver related mortality via complications of liver cirrhosis or hepatocellular carcinoma, and affects more than 185 million persons worldwide. Antiviral therapy evolved during the past 25 years from standard interferon, the combination with ribavirin and pegylated interferon (P/R) to the addition of protease inhibitors and is currently on the edge to an interferon-free era with the first such substances being approved in 2014. However, current standard therapy for CHC genotype 1 patients without cirrhosis consists of ribavirin and pegylated interferon (P/R) in combination with boceprevir (BOC) or telaprevir (TPV), which are direct acting antivirals and represent the first-generation protease inhibitors.

Triple therapy for CHC has been reported to be associated with a quantitative and qualitative increase in treatment-related (serious) adverse events compared to the former standard therapy without protease-inhibitors. Moreover, reports of serious infectious complications during triple therapy - especially in patients with acquired immune deficiencies like liver cirrhosis - that lead to considerable morbidity and mortality, have accumulated recently. The mechanisms of this increased susceptibility to infections remain unclear. However, BOC is known to inhibit neutrophil elastase activity.

Aims of this study were therefore to analyse infections that occurred in CHC outpatients during therapy in the study centre, to prospectively characterize neutrophil function in patients undergoing CHC triple therapy in comparison to dual therapy with peginterferon and ribavirin and to thereby elucidate the possible mechanisms of protease-inhibitor associated infections.
