BACKGROUND: In Egypt, the prevalence of chronic hepatitis C (CHC) infection is 13.8% of whole population and about 80% of the patients with hepatocellular carcinoma have underling hepatitis C. AIM: This study was designed to assess the diagnostic value of plasma miR-122 and miR-21 in patients with CHC, genotype-4, to detect fibrosis progression versus noninvasive indices and their diagnostic value in detection of early stages of hepatocellular carcinoma (HCC). METHODOLOGY: A prospective study that included 180 patients, divided into 3 groups: healthy controls (group I), CHC patients (group II), and hepatitis C patients with HCC (group III); all cases were subjected to thorough clinical, radiological, and laboratory investigations...

The influence of hepatitis B virus (HBV) genotypes in the natural history of the disease and its response to antiviral treatment have been addressed in many studies. In Brazil, studies on HBV genotype circulation have been restricted to specific population groups and states. Here, we have conducted a nationwide multicentre study with an unprecedented sample size representing all Brazilian regions in an effort to better understand the viral variants of HBV circulating among chronic carriers. Seven HBV genotypes were found circulating in Brazil...

BACKGROUND: Hepatitis E virus (HEV) is a major cause of acute viral hepatitis in areas with poor sanitation. Rabbit is one of important animal reservoirs of the virus. Reverse transcription-loop-mediated isothermal amplification (RT-LAMP) system is a novel nucleic acid amplification assay, for which the specificity and sensitivity are much higher than that of conventional PCR. However, previously reported RT-LAMP system cannot detect rabbit HEV, which was identified recently and seems to be another potential source of human HEV infection...

BACKGROUND & AIMS: Little is known about the epidemiology and frequency of recombinant HCV genotype 2/1 strains which may represent a challenge for direct antiviral therapy (DAA). METHODS: Consecutive samples from HCV genotype 2 infected patients from Germany, Italy and Israel according to commercial genotyping were re-genotyped by Sanger-based sequencing. Virologic, epidemiological, and phylogenetic analyses including other published chimeras were performed. RESULTS: Sequence analysis of 442 supposed HCV genotype 2 isolates revealed 61 (genotype 2k/1b (n=59), 2a/1b (n=1) or 2b/1a (n=1)) chimeras...

BACKGROUND AND AIMS: Interferon (IFN)- free direct antiviral agents (DAAs) with rapid HCV eradication might evoke immunological reconstitutions, and some early recurrences of HCC after IFN-free DAAs have been reported. This study aimed to investigate whether natural killer group 2, member D (NKG2D) predicts early emergence of HCC after IFN-free DAAs. METHODS: We conducted a clinical practice-based observational study of 101 patients infected with genotype 1 HCV who received IFN-free (DAAs), and stratified them into those who did or did not develop early (i...

OBJECTIVE: Lipid homoeostasis is disturbed in patients with HCV infection. Direct-acting antiviral agent (DAA) treatment eradicates chronic HCV viraemia, but the dynamics of lipid components remain elusive. This study investigates the clinical manifestation and mechanistic relevance of plasma triglyceride (TG), cholesterol (Chol), lipoproteins and apolipoproteins (apos) after DAA treatment. DESIGN: Twenty-four patients with chronic genotype 1 (GT1) HCV treated with elbasvir/grazoprevir or ledipasvir/sofosbuvir for 12 weeks, and followed-up thereafter, were recruited...

Background Hepatitis C virus (HCV) cure rates have been similar in patients with and without HIV co-infection; however, in the ION-4 study, black patients treated with ledipasvir/sofosbuvir were significantly less likely to achieve cure (90%) compared to non-black patients (99%). There are limited real world data on the effectiveness of oral direct acting antivirals (DAAs) in predominantly minority HIV/HCV co-infected populations. Methods We analyzed HCV treatment outcomes among 255 HCV co-infected patients initiating DAAs between February 2014 and March 2016 in an urban clinic in Baltimore, Maryland...

HBsAg point mutations within the major hydrophilic region (MHR) have frequently been reported to be associated with diagnostic failure, vaccine escape and immunotherapy escape. However, the prevalence of escape mutations in chronic hepatitis B (CHB) patients has not been systematically studied in patients from southern China within the past decade. This study aimed to determine the prevalence of escape mutations within the MHR of hepatitis B virus in patients in Dongguan, southern China. Between June 2015 and May 2016, 391 patients who were chronically infected with HBV were enrolled in the study, including 240 patients with the genotype B strain and 151 with the genotype C strain...

Relevant resistance-associated substitutions (RASs) to elbasvir, the new HCV NS5A inhibitor, may limit its efficacy and lead to virological failure in HCV-GT1a-infected patients. There are few data outside clinical trials evaluating their prevalence and impact of elbasvir/grazoprevir. A multicenter cross-sectional study of 617 HCV-GT1a-infected individuals attended in 84 Spanish hospitals from the 17 Autonomous Communities and two Autonomous cities was performed. HCV population sequencing was used to identify RASs to elbasvir and the mutational pattern and drug sensitivity were confirmed by geno2pheno[HCV]...
