BACKGROUND & AIMS Interferon alfa-based regimens used to treat recurrent hepatitis C virus (HCV) infection after liver transplantation are poorly tolerated, associated with generally modest efficacy, and can interact with immunosuppressive agents. We evaluated the efficacy and safety of an interferon-free regimen of the nucleotide polymerase inhibitor sofosbuvir combined with ribavirin for 24 w...
Among 103 patients with multidrug-resistant HIV who initiated raltegravir, etravirine, and darunavir/ritonavir-containing regimen in the ANRS 139 TRIO trial, 100 participated in extended follow-up and continued study treatment until week 96. Among them, 87 (87%) received an optimized background therapy including either nucleoside reverse transcriptase inhibitors or enfuvirtide, they were 78 (78...
Antiviral therapy for chronic hepatitis C has advanced dramatically since the discovery of the hepatitis C virus and the introduction of interferon in early 1990's. An initial treatment regimen, 24 weeks of interferon monotherapy, achieved sustained virologic response, which is formally defined at 24 weeks after completion of the treatment, only for 5% of patients with genotype 1 high-viral loa...
Undetectable hepatitis C virus (HCV)-specific RNA in serum six months after the end of treatment is the primary aim of antiviral therapy in patients with chronic hepatitis C. Long-term studies confirmed that viral eradication is durable in more than 95% of cases. The high chronification rate of acute hepatitis C (50 to 80%) justifies therapeutic strategies to prevent a chronic course of the inf...
Hepatitis C virus infection is causing chronic liver disease, cirrhosis, and hepatocellular carcinoma. By combining direct-acting antivirals (DAAs), high sustained virologic response rates (SVRs) can be achieved. Resistance-associated substitutions (RASs) are commonly observed after DAA failure, especially nonstructural protein 5A (NS5A) RASs may impact retreatment options.1–3 Data on of failur...
