HCC is a typical inflammation-related cancer, and genetic variations within the IL-37 gene may be associated with the risk of HBV infection. Identification of the allelic patterns that genetically have a high disease risk is essential for the development of preventive diagnostics for HBV-mediated liver disease pathogenesis.

Viral mutations acquired during the course of chronic hepatitis B virus (HBV) infection are known to be associated with the progression and severity of HBV-related liver disease. This study of HBV-infected Saudi Arabian patients aimed to identify amino acid substitutions within the precore/core (preC/C) region of HBV, and investigate their impact on disease progression toward hepatocellular carcinoma (HCC). Patients were categorized according to the severity of their disease, and were divided into the following groups: inactive HBV carriers, active HBV carriers, liver cirrhosis patients, and HCC patients.

To assess the safety and efficacy of PegIFNalfa-2a in combination with an adjusted (ADJ) RBV dose based on early pharmacokinetics versus a fixed standard (STD) dose of RBV in chronic HCV genotype (GT) 4-naive patients in a randomized trial. One hundred eighty-one patients were randomized.

It presents in the early adulthood mainly as cardiomyopathy, hypogonadism and liver fibrosis. Unlike hereditary hemochromatosis due to HFE mutation, hepatocellular carcinoma is not known to be associated with juvenile hemochromatosis.

Here, we use virus genetic data to identify the transmission dynamics that drive the hepatitis C virus subtypes 4a (HCV4a) and 4d (HCV4d) epidemics in Saudi Arabia. We use a comprehensive dataset of newly generated and publicly available sequence data to infer the HCV4a and HCV4d evolutionary histories in a Bayesian statistical framework.

The protein encoded by PARK2 gene is a component of the ubiquitin-proteasome system that mediates targeting of proteins for the degradation pathway. Genetic variations at PARK2 gene were linked to various diseases including leprosy, typhoid and cancer.

However, the correlation of achalasia subtypes with clinical, endoscopic, and radiologic findings has not been assessed. We aimed to evaluate and compare the clinical, endoscopic, and fluoroscopy findings associated with three subtypes of achalasia using HRM.

The aim of the study was to correlate the serum level of IL28B in HCV-infected patients with virus genotype/subgenotype and disease progression. IL28B serum level was detected and variations at five single nucleotide polymorphisms (SNPs) in IL28B gene region were genotyped and analyzed.

This study was conducted to assess the association of DEPDC5 variants with advanced liver cirrhosis and HCC development among chronic HCV-infected patients in Saudi Arabian population.
Methods: Six-hundred and one HCV-infected patients were genotyped for DEPDC5 polymorphisms (rs1012068 and rs5998152), in comparison with 592 non-infected healthy control subjects.
Hepatitis C virus (HCV) is a single stranded RNA virus. It affects millions of people worldwide and is considered as a leading cause of liver diseases including cirrhosis and hepatocellular carcinoma. A recent study reported that TLR4 gene polymorphisms are good prognostic predictors and are associated with protection from liver fibrosis among Caucasians.
View Article and Find Full Text PDFObjectives: Patients with chronic hepatitis B virus (HBV) may exhibit significant liver pathology despite alanine aminotransferase (ALT) and HBV DNA levels below the cutoff values advised by treatment guidelines. We evaluated candidacy for HBV therapy when baseline histopathological changes are taken into consideration.
Methods: Clinical, biochemical, serological, virological, and histopathological (METAVIR score) data of 117 patients with HBeAg-negative chronic HBV genotype D were collected and analyzed.
Background: Hepatitis C virus (HCV) shows a remarkable genetic diversity, contributing to its high persistence and varied susceptibilities to antiviral treatment. Previous studies have reported that the substitution of amino acids in the HCV subgenotype 1b core protein in infected patients is associated with a poor response to pegylated interferon and ribavirin (PEG-IFN/RBV) combined therapy.
Objectives: Because the role of the core protein in HCV genotype 4 infections is unclear, we aimed in this study to compare the full-length core protein sequences of HCV genotype 4 between Saudi patients who responded (SVR) and did not respond (non-SVR) to PEG-IFN/RBV therapy.
Hepatitis B virus (HBV) infection is a leading cause of liver diseases including cirrhosis and hepatocellular carcinoma. Human leukocyte antigens (HLAs) play an important role in the regulation of immune response against infectious organisms, including HBV. Recently, several genome-wide association (GWAS) studies have shown that genetic variations in HLA genes influence disease progression in HBV infection.

This study was conducted to examine the role of genetic variations in IL28B on disease progression in Saudi Arabian patients chronically infected with hepatitis B virus (HBV).
Methods: The study included 1128 subjects divided into four categories; 304 clearance subjects, 518 inactive carriers, 212 active carriers and 94 cirrhosis/HCC.
MHC class I polypeptide-related chain A (MICA), mapping to 6p21.33, belongs to the non-classical class I family and its expression is induced by several stress factors including viral infection.

A 19-years-old girl was referred for lung transplant due to end stage lung disease secondary to idiopathic bilateral bronchiectasis. Her routine pre lung transplant evaluation showed normal esophageal high-resolution manometry (HRM) and 24-hours impedance pH monitoring. Four weeks after the bilateral sequential lung transplantation (LTx), she developed dysphagia, chest pain and regurgitation, complicated by aspiration pneumonia.
View Article and Find Full Text PDFBackground: Genome-wide association studies have recently revealed that several single-nucleotide polymorphisms (SNPs) in the interleukin (IL) 28B genes can predict the sustained virological response (SVR) to pegylated interferon-α2a/b plus ribavirin in hepatitis C virus (HCV)-genotype 1 patients. However, data for patients infected with HCV genotype 4 (HCV-G4) are limited.
Aim: We analyzed the association of IL28B SNPs (hematological, biochemical, virological, and pathological factors) with SVR in the HCV-G4 monoinfected cohort of patients.
Introduction: The role of serum interferon-γ-inducible protein-10 kDa (IP-10) level in the treatment of chronic hepatitis C genotype-4 (HCV-4) and its various subtypes remains unknown. We aimed to study the impact of pretreatment IP-10 levels on the sustained viral response (SVR) in HCV-4 patients (n=64) undergoing peginterferon α-2a/ribavirin therapy.
Patients And Methods: Pretreatment IP-10 levels and HCV-4 subtypes (4a=48.
A gastrosplenic fistula is a rare complication of a gastric or splenic lesion. We report a case of Hodgkin's lymphoma nodular sclerosis involving the spleen that was complicated by spontaneous gastrosplenic fistula. The fistula was closed laparoscopically, and the patient underwent partial gastrectomy and gastric wall repair, followed by successful chemotherapy.
