Background And Aim: The data on the prevalence and predictors of significant fibrosis (≥F2, METAVIR) in chronic hepatitis B virus (HBV) patients with low viremia are limited. We aimed to assess both the prevalence predictors of ≥F2 fibrosis in hepatitis B envelope antigen-negative patients with HBV DNA <20,000 IU/mL.
Methods: Hepatitis B envelope antigen-negative patients (n=213) with mean HBV DNA <2000 IU/mL (n=97) and HBV DNA 2000 to 20,000 IU/mL (n=116) were included and all had liver biopsy.
Background: 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.
Aim: To identify the seroprevalence of celiac disease among healthy Saudi adolescents.
Methods: Between December 2007 and January 2008, healthy students from the 10(th) to 12(th) grades were randomly selected from three regions in Saudi Arabia. These regions included the following: (1) Aseer region, with a student population of 25512; (2) Madinah, with a student population of 23852; and (3) Al-Qaseem, with a student population of 16067.

Some 400 million people worldwide are currently infected with the hepatitis B virus (HBV), and the infection is common in the Middle East. Another 170 million people around the globe presently live with chronic hepatitis C virus (HCV) infection. Both HBV and HCV represent a worldwide epidemic.

However, the seroprevalence of viral hepatitis A (HAV) underwent a marked decline in the last two decades from over 50% in 1989 to 25% in 1997 among Saudi children under the age of 12 years. The aim of this paper was to study seroprevalence rates of H.

We aimed to investigate whether the quasispecies population could be used as a predictor of response to therapy in our patients.
Methods: The quasispecies of HCV genotype 4 (HCV-4) were studied in 25 naïve Saudi patients at zero, three, and six months following interferon alfa and ribavirin combination therapy.
Chronic liver disease is accompanied by derangement of hepatocyte function including the synthesis of haemostastic factors. It is, however, not known whether the improvement in liver functions as a result of interferon (IFN)-alpha therapy would be reflected in the plasma levels of these factors. To evaluate the effect of IFN-alpha therapy on the plasma levels of natural anticoagulants and on the fibrinolytic parameters, in patients with chronic viral hepatitis.

Methods: Patients were consecutively recruited from the hepatology clinics of two tertiary care referral centers. Patients were categorized into 4 different groups: group 1, patients with hepatitis B and normal liver enzymes; group 2, patients with hepatitis B and abnormal liver enzymes but without cirrhosis; group 3, patients with hepatitis B and liver cirrhosis; group 4, patients with hepatitis B and hepatocellular carcinoma.
Objective: To identify the most common liver pathologies seen in our center, to find the prevalence of advanced fibrosis and cirrhosis in patients with chronic hepatitis B and C, and to correlate the histological and laboratory features of the most common diseases and compare between them.
Methods: Liver biopsy procedures performed in our Gastroenterology Unit at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia were traced from records between the years 1997-2003. Clinical, histopathological, and laboratory features were recorded.
Background: Information on the epidemiology of viral hepatitis B, C and A in the Kingdom of Saudi Arabia (KSA) has accumulated over the last two decades. We review the changing epidemiology of these infections and suggest possible strategies for eradication.
Methods: We screened Saudi medical journals and Medline for reports dealing with hepatitis B, C and A, and analyzed official of blood donor screening data from the Ministry of Health (MOH) Central Blood Bank and the King Khalid University Hospital (KKUH) Blood Bank.
Background: The role of steatosis in the pathogenesis of chronic liver disease (CLD) is now believed to form part of a continuum in non-alcoholic fatty liver disease (NAFLD). One of the unconventional areas in which leptin is now receiving great attention is liver diseases. Several published studies indicate that circulating leptin is increased in patients with cirrhosis, chronic HCV, and non-alcoholic steatohepatitis (NASH).

Nonetheless, no haemostatic test(s) is included among the routine liver function tests and this study aims to probe this possibility. The liver disease group (n=258) included acute hepatitis (n=25), chronic viral hepatitis (n=128), hepatitis B (HB) carriers (n=25), liver cirrhosis (n=67), and hepatocellular carcinoma (HCC) (n=13).

The aim of this study was to identify the clinical, biochemical and or radiological predictors of malignant biliary strictures.
Methods: We retrospectively reviewed all charts of patients who had biliary strictures (BS) on endoscopic retrograde cholangiopancreatography (ERCP) or percutaneous cholangiography (PTC) in case of unsuccessful ERCP from March 1998 to August 2002.
Objective: To identify the cause, methods of diagnosis and management of malignant biliary strictures in our institution and compare with studies from other communities.
Methods: From March 1998 through to August 2002, we reviewed 1000 files of patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) at the Gastroenterology unit, King Khalid University Hospital in Riyadh, Kingdom of Saudi Arabia for malignant biliary strictures (MBS). Clinical, laboratory data, method of diagnosis and management were recorded.
Background: Saudi Arabia used to be hyperendemic for HBV infection. Most of infection occurs in early life. HBV vaccine was, therefore, introduced in 1989 as the seventh primary immunogen of the EPI Program.
