OBJECTIVES Serum hepatitis C virus (HCV) core antigen (HCVcAg) concentrations correlate with HCV RNA levels in HCV monoinfected patients. Data in HCV/HIV coinfected patients are still limited. We aim to compare the use of HCVcAg measurement with respect to HIV status, HCV genotypes, interferon-lambda-4 (IFNL4) polymorphism and clinical parameters. METHODS We analyzed an untreated cohort of 10...

Recent many studies indicated a novel dinucleotide variant in ss469415590 (TT vs. ΔG) of interferon-λ 4 (IFNL4) gene strongly associated with hepatitis C virus clearance. To evaluate the impact and clinical usefulness of IFNL4 ss469415590 genotype on predicting both spontaneous HCV clearance and response to therapy in Chinese population, we genotyped 795 chronic HCV carriers, 460 subjects with ...

BACKGROUND The interleukin-28B (IL28B) gene polymorphism is a strong baseline predictor of sustained virological response (SVR) in hepatitis C virus (HCV) treatment. The length of thymine--adenine dinucleotide repeats, or (TA)n, in the regulatory region of IL28B can affect interferon transcription. In order to determine predictive values in HCV infection, we explored the correlation among facto...

AIMS Genome-wide association studies highlighted single nucleotide polymorphisms (SNPs) within the IFNL3/IL28B locus predict the treatment outcome for patients with HCV. Furthermore, SNPs in newly discovered IFNL4 are shown to have population-specific correlation with spontaneous clearance of HCV. The aim of this study was to examine the prevalence and clinical significance of the outlined SNPs...

background: a dinucleotide variant rs368234815 in interferon lambda 4 (ifnl4) gene was recently found to be associated with the hepatitis c virus (hcv) treatment response. this study aimed to assess the impact of ifnl4 rs368234815 polymorphism on treatment response to pegylated?ifn alpha (peg?ifn??) and ribavirin (rbv) in hemophilic patients with chronic hepatitis c (chc). materials and methods...

AIM To analyze the genetic heterogeneity of the Amerindian and admixed population (Mestizos) based on the IL28B (rs12979860, rs8099917) and IFNL4 (rs368234815) haplotypes, and their association with spontaneous clearance (SC) and liver damage in patients with hepatitis C infection from West Mexico. METHODS A total of 711 subjects from West Mexico (181 Amerindians and 530 Mestizos) were studie...

conclusions the growth rate of information in bioinformatics databases could facilitate studies of live organisms prior to observation studies. two different protein classes could be causative agents of one disease. however, two related diseases from one disease group could consist of different protein classes. future research in the field of proteomics could allow modern insight to reshuffling...

context there is growing evidence that interferon lambda 4 (ifnl4) polymorphism is related to sustained virological response (svr) in hepatitis c virus (hcv) infection. we analyzed the relationship between ifnl4 (rs368234815) polymorphism and svr in dual- and triple- therapy in hcv genotype 1, 2, 3 and 4 infected asian, caucasian and african patients. conclusions favorable ifnl4 rs368234815 gen...

background hepatitis c virus (hcv) is the major cause of chronic liver disease. hcv is a single stranded positive sense rna of approximately 9.6 kb. because of high conservativeness of 5΄untranslated region of hcv genome, it is widely used for virus genotyping. different methods are used for the virus genotyping, but all involve some difficulties. objectives the aim of the present study was to ...
