Hepatitis C Virus: Efficacy of New DAAs Regimens

Abstract

Background: HCV treatment showed dramatical change due to the introduction of potent, strong, direct antiviral drugs. Before the appearance of Direct-acting antivirals, multiple therapeutic interventions were used for hepatitis C, but none of these interventions were effective on patient-centered outcomes. Direct-acting antivirals cause disruption of viral replication because they target specific nonstructural viral proteins.

Aim: To review the advantages of efficient HCV therapy and its long term drawbacks.

Methods: A search of the literature published in indexed databases (PubMed, Medline In-Process, and Embase) within the last 5 years was conducted. Any duplicated citations were excluded before first-pass screening. Citations (titles and abstracts) were screened for eligibility by a single reviewer. Full texts (including congress abstracts, posters and other congress communications) of citations deemed relevant during title and abstract screening were retrieved for second-pass review.

Results: Studies on the clinical effects of DAAs for hepatitis C show better tolerance, improved survival and fewer complications when compared to previous interferon therapy.

Conclusion: HCV treatment has improved dramatically. Since that time, there are multiple approved oral therapies all with high efficacy. The most important factor which should be considered during choosing appropriate therapy is to ensure that it covers the viral genotype of the infected patients.
