Recent discoveries have highlighted the influence of host genomics on hepatitis C virus (HCV) infection outcomes. As a result, our views on hepatitis C pathogenesis and therapeutic approaches have been transformed. The recognition of the impact of single-nucleotide polymorphisms (SNPs) of the genes interleukin 28B (IL28B), inosine triphosphatase (ITPA) and low-density lipoprotein cholesterol re...

Ribavirin remains an important component of hepatitis C treatment in certain clinical scenarios, but it causes hemolytic anemia. A quantitative understanding of the ribavirin exposure-anemia relationship is important in dose individualization/optimization. We developed a model relating ribavirin triphosphate (RTP) exposure in red blood cells (RBCs), RBC lifespan, feedback regulation of RBC prod...

rs12979860 in interleukin 28B (IL28B) gene is associated with response to interferon-α therapy and natural viral clearance in hepatitis C. The role of this polymorphism is less known in hepatitis B virus (HBV) infection. We evaluated whether rs12979860 was associated with outcomes of HBV infection. There were 651 individuals with persistent infection (387 with liver cirrhosis, 264 without cirrh...

The development of direct-acting antivirals with activity against hepatitis C virus (HCV) has been a major breakthrough. The Phase III clinical trials of the protease inhibitors boceprevir and telaprevir have shown that both of these agents substantially improve rates of sustained virological response in patients with genotype 1 HCV infection. However, both agents must be combined with pegylate...

Hepatitis C virus (HCV) is a bloodborne infection that is one of the leading causes of liver disease. If left untreated, HCV can lead to cirrhosis, hepatocellular carcinoma, and death. The current standard of care for HCV is a combination of pegylated-interferon (peg-IFN) and ribavirin (RBV) in which the goal of treatment is to decrease complications and death due to HCV. HCV displays genetic p...

Several host (age, sex, race, fibrosis stage, interleukin 28B polymorphism) and viral factors (hepatitis C virus [HCV] genotype, viral load) allow estimating the response to interferon-based therapies (which includes first-generation protease inhibitors) before treatment. However, treatment should not be denied to any patient based on unfavorable factors alone. Metabolic conditions associated w...

The aim of the study was to assess the effect of pasteurisation, as set by the European regulation EC 1774/2002, on selected pathogens and indicator organisms. Unpasteurised substrate (biowaste), including animal by-products from a full-scale biogas plant was heat treated under laboratory conditions at 70 degrees C and 55 degrees C for 30 min and 60 min. Heat treatment at 55 degrees C for 60 mi...
