BACKGROUND Changes in DNA methylation patterns are believed to be early events in hepatocarcinogenesis. A better understanding of methylation states and how they correlate with disease progression will aid in finding potential strategies for early detection of HCC. The aim of our study was to analyze the methylation frequency of tumor suppressor genes, P14,(More)
BACKGROUND IL28B single nucleotide polymorphisms (SNPs) play important roles in the management of hepatitis C virus (HCV) infections and are strongly associated with spontaneous and treatment-induced HCV clearance. OBJECTIVES In the present study, the association between IL28B variants and the progression of HCV infection in Egyptian patients infected(More)
BACKGROUND AND STUDY AIM Quality of life after liver donation must remain a primary outcome measure when we consider the utility of living donor liver transplants. In making clinical decisions on the use of transplantation for chronic liver diseases, consideration should be given to the key factors likely to affect subsequent health related quality of life.(More)
To evaluate the frequency of single-nucleotide polymorphism at the -88 myxovirus resistance (MxA) gene promoter region in relation to the status of hepatitis C virus (HCV) progression and response to combined interferon (IFN) in chronic HCV Egyptian patients. One hundred ten subjects were enrolled in the study; 60 HCV genotype 4-infected patients who(More)
BACKGROUND Hepatic fibrosis is an inclusion indicator for treatment and a major independent predictor of treatment response in patients with chronic hepatitis C. Liver biopsy, considered as the "gold standard" for evaluating liver fibrosis, has carried some drawbacks. Currently used noninvasive predictors of fibrosis are considered less accurate than liver(More)
BACKGROUND/AIMS In Egypt, hepatitis C virus (HC is highly endemic with at least 91% are genotype-4. However, HCV-specific burden data for Egypt are scarce. The study aims to identify clinical, biochemical and pathological features of chronic HCV population in Egypt. METHODOLOGY We analyzed retrospective data of 5,464 HCV-antibody and PCR positive patients(More)
BACKGROUND Liver disease progression from chronic hepatitis C virus (HCV) infection to hepatocellular carcinoma (HCC) is associated with an imbalance between T-helper 1 and T-helper 2 cytokines. Evaluation of cytokines as possible candidate biomarkers for prediction of HCC was performed using soluble Fas(sFas), soluble tumor necrosis factor receptor-II(More)
BACKGROUND AND AIM Cytomegalovirus (CMV) is a ubiquitous pathogen that infects the majority of humans. Co-infection of CMV and hepatitis C virus (HCV) may deteriorate the prognosis of HCV-infected patients. This study was conducted to examine the role of CMV reactivation in determining the response rate to treatment with interferon and ribavirin therapy in(More)
Combined pegylated interferon-α and ribavirin therapy has sustained virological response (SVR) rates of 54% to 61%. Pretreatment predictors of SVR to interferon therapy have not been fully investigated yet. The current study assesses a group of chemokines that may predict treatment response in Egyptian patients with chronic HCV infection. CXCL5, CXCL9,(More)
BACKGROUND/AIM Infection with hepatitis C virus (HCV) frequently results in a persistent infection, suggesting that it has evolved efficient mechanism(s) for blocking the host cell's innate antiviral response. The immune response to virus infection results in activation or direct induction of the interferon regulatory factors (IRFs), which are a family of(More)
