BACKGROUND The hepatitis C virus (HCV) Alternate Reading Frame Protein (ARFP or F protein) presents a double-frame shift product of the HCV core gene. We and others have previously reported that the specific antibodies against the F protein could be raised in the sera of HCV chronically infected patients. However, the specific CD4(+) T cell responses against the F protein during HCV infection a...
BACKGROUND & AIMS Infectious hepatitis C virus (HCV) particles bind to host lipoproteins such as low-density lipoproteins (LDLs). Low-density lipoprotein receptors (LDLR) have been termed candidate receptors for HCV-LDL complexes. Functional host genetic single nucleotide polymorphisms (SNPs) in the apolipoprotein E (APOE) gene encoding apolipoprotein E (apoE) - a major structural LDL component...
Aims: To study the frequency and clinical correlation of Hepatitis B for common genotypes of hepatitis B virus by PCR. Methods: HBV genotype was determined from 206 serum samples from chronically infected patients with HBV. DNA was extracted from HBsAg and HbeAg positive cases and their genotype were identified by using type specific primers. Results: All the genotypes except genotype E were id...
Introduction: Acute hepatitis has several causes. Transfusion of non-infected blood to the virus and avoidance of undesirable social contacts have reduced the prevalence of hepatitis B and C transmission. Improved socioeconomic status and access to healthy food and water have also reduced the prevalence of hepatitis E and A. The transition from Hyper Endimicity to Intermediate or Low Endimicity...
Fourteen hepatitis C virus (HCV) chronically infected patients were submitted to routine liver biopsy for histological evaluation. Liver samples were assayed to HCV-RNA by in situ hybridization, using digoxigenin labeled probe. HCV genotypes were found to be predominantly type 1 (71.4%), followed by genotype 3 (21.4%), and genotype 2 (7.2%). Alanine-aminotransferase levels were raised in 10 pat...
Background Occult hepatitis B infection (OBI) is considered a risk factor for progression of liver disease in patients with hepatitis B virus (HBV) infection. This disease progression is reported to be more significant in those with concomitant HIV infection. We aimed to determine the prevalence rate of OBI in a sample of HIV-positive patients. Materials and Methods: Sixty-six HIV-infected pati...
Background Hepatitis B viral represents a pathology with a severe impact on public health. Worldwide, approximately 350 million individuals are chronically infected with hepatitis B virus (HBV). HBV is the leading cause of cirrhosis globally. Once chronic infection is established, approximately 30% of the patients will develop cirrhosis, and approximately one-quarter of patients with cirrhosis ...
Background and purpose: More than 3% of the world population are infected with Hepatitis Ç virus (HÇV) and 50-80% of these patients progress to chronic disease. Âpproximately 50% of chronically infected patients do not respond to treatment. The purpose of this study was to determine the risk factors for hepatitis Ç virus among high-risk populations (Ïntravenous drug addicts and patients with ...
Background and purpose: The standard of care treatment for infected patients with HCV is based on a combination of pegylated interferon alpha and ribavirin. Recently, the rs12979860 SNP polymorphism, located upstream of the interleukin 28B gene, was shown to be strongly associated with response to anti-HCV therapy. This study investigated the distribution of the (C/T) polymorphism with sust...
BACKGROUND It has been reported that several baseline polymorphisms of direct-acting antivirals (DAAs) agents resistance-associated variants (RAVs) would affect the treatment outcomes of patients chronically infected with hepatitis C virus (CHC). The aim of this study is to investigate the prevalence of DAAs RAVs in treatment-naÏve GT1b CHC patients. METHODS Direct sequencing and ultra-deep s...
