BACKGROUND Genetic variation in the IL28B gene has been strongly associated with treatment outcomes, spontaneous clearance and progression of the hepatitis C virus infection (HCV). The aim of the present study was to investigate the role of polymorphisms at this locus with progression and outcome of HCV infection in a Moroccan population. METHODS We analyzed a cohort of 438 individuals among ...
Spontaneous clearance of hepatitis C virus (HCV) occurs in 10-40% of the infections. Specific human leukocyte antigen (HLA) alleles have been identified in associating with HCV clearance. However, data on the association of HLA with the spontaneous clearance of HCV are scarce in the Chinese population. In the current study we studied the HLA class I and class II genes in 231 Chinese voluntary b...
It is not known how the immune system targets hepatitis C virus (HCV)-infected HLA-mismatched hepatocytes under immune-suppressed conditions after orthotopic liver transplantation (OLT). In addition, the relationship between the HCV-specific immune response and IL28B variants as predictors of HCV clearance has not been well-characterized. We determined the IL28B polymorphisms for 57 post-OLT HC...
OBJECTIVE Pegylated-interferon/ribavirin (peg-IFN/RBV) therapy with a protease inhibitor is the standard therapy for genotype 1b chronic hepatitis C. Despite improving treatment outcomes, patients with thrombocytopenia are often difficult to treat because interferon commonly exacerbates thrombocytopenia. In this study, partial splenic embolization (PSE) was performed in patients with hypersplen...
BACKGROUND Patients infected with hepatitis C virus (HCV) genotype 1 respond poorly to standard treatment with 50% or less achieving sustained virologic response. Predicting outcome is essential and could help avoid unnecessary treatment and reduce health cost. Recently, an association of amino acid substitutions in the core region and treatment outcome was observed in Japanese patients. In the...
Simeprevir plus peg-interferon/ribavirin (PR) is approved to treat chronic hepatitis C (HCV) genotype 1 (GT1) and GT4 infection. This study aimed to assess baseline and on-treatment the factors predictive of sustained virologic response 12-weeks post-treatment (SVR12) in patients receiving 12 weeks of simeprevir plus PR followed by 12 or 36 weeks of PR. Data from participants in four studies (Q...
BACKGROUND & AIMS Since acute hepatitis C virus (HCV) infection is often asymptomatic, it is difficult to examine the rate and determinants of spontaneous clearance. Consequently, these studies are subject to bias, which can potentially lead to biased rates of viral clearance and risk estimates. We evaluated determinants of spontaneous HCV clearance among HCV seroconverters identified in a uniq...
UNLABELLED Chronic hepatitis C (CHC) infection is a leading cause of endstage liver disease. Current standard-of-care (SOC) interferon-based therapy results in sustained virological response (SVR) in only one-half of patients, and is associated with significant side effects. Accurate host predictors of virologic response are needed to individualize treatment regimens. We applied a label-free li...
Pegylated-IFN and ribavirin remains the current treatment for chronic HCV infection in patients co-infected with HIV-1, but this regimen has low efficacy rates, particularly for HCV genotype 1/4 infection, has severe side effects and is extremely costly. Therefore, accurate prediction of treatment response is urgently required. We have recently shown that the NK cell gene, KIR2DS3 and a SNP ass...
