ABSTRACT Background This study aimed to evaluate the clinical effectiveness in terms of sustained virological response and tolerability of available second generation direct-acting antivirals in Brazilian patients. Methods This was a retrospective observational study conducted in six centers in Southern Brazil. The sample comprised adult patients who were chronically infected with hepatitis C virus, regardless of virus genotype, fibrosis stage, or prior treatment. Statistical analysis was performed to compare the effectiveness among the treatments, and also to uncover the factors influencing the achievement of sustained virological response. Results A total of 296 patients were included in the study, with the majority receiving sofosbuvir with...

Prevalence of IFNL3 gene polymorphism among blood donors and its relation to genomic profile of ancestry in Brazil 55

ABSTRACT The recent development of interferon-free regimens based on direct-acting antivirals for the treatment of chronic hepatitis C virus infection has benefited many but not all patients. Some patients still experience treatment failure, possibly attributed to unknown host and viral factors, such as IFNL3 gene polymorphism. The present study assessed the prevalence of rs12979860-CC, rs12979860-CT, and rs12979860-TT genotypes of the IFNL3 gene, and its relationship with ancestry informative markers in 949 adult Brazilian healthy blood donors. Race was analyzed using ancestry informative markers as a surrogate for ancestry. IFNL3 gene was genotyped using the ABI TaqMan single nucleotide polymorphisms genotyping assays. The overall frequency of...

Resistance mutations of NS3 and NS5b in treatment-naïve patients infected with hepatitis C virus in Santa Catarina and Rio Grande do Sul states, Brazil 74

Abstract Hepatitis C virus (HCV) infection is a worldwide health problem. Nowadays, direct-acting antiviral agents (DAAs) are the main treatment for HCV; however, the high level of virus variability leads to the development of resistance-associated variants (RAVs). Thus, assessing RAVs in infected patients is important for monitoring treatment efficacy. The aim of our study was to investigate the presence of naturally occurring resistance mutations in HCV NS3 and NS5 regions in treatment-naïve patients. Ninety-six anti-HCV positive serum samples from blood donors at the Center of Hematology and Hemotherapy of Santa Catarina State (HEMOSC) were collected retrospectively in 2013 and evaluated in this study. HCV 1a (37.9%), 1b (25.3%), and 3a (36.8%) subtypes...
