BACKGROUND Cell-mediated immune (CMI) responses to hepatitis C virus (HCV) antigens in adults without seroconversion or viremia are biomarkers for prior transient infection. We investigated HCV-specific CMI responses in seronegative children living with HCV-infected siblings. METHODS Children 3-18 years of age living with HCV-infected siblings were(More)
INTRODUCTION Liver biopsy, although a gold standard in diagnosis of nonalcoholic fatty liver disease (NAFLD), is an invasive and expensive tool. AIM To assess the diagnostic accuracy of abdominal ultrasound in detecting NAFLD among a group of overweight/obese children having one or more liver abnormality (clinical hepatomegaly, raised ALT or echogenic(More)
BACKGROUND/AIM To study the prevalence of metabolic syndrome (MS), insulin resistance (IR) and non-alcoholic fatty liver disease (NAFLD) in overweight/obese children with clinical hepatomegaly and/or raised alanine aminotransferase (ALT). PATIENTS AND METHODS Thirty-three overweight and obese children, aged 2-13 years, presenting with hepatomegaly and/or(More)
BACKGROUND AND AIM Children with type 1 diabetes mellitus (T1DM) are frequently investigated for hepatic abnormalities. This study was carried out to report on the prevalence of hepatic abnormalities in diabetic children and adolescents and to highlight the possible etiology and appropriate management. METHODS The study included 692 children (333 were(More)
BACKGROUND AND AIM We aimed to evaluate the accuracy of readily available laboratory tests (ALT, AST, platelet count, AST to platelet ratio index: APRI) in predicting liver fibrosis in chronic hepatitis C, in comparison to the predictive accuracy obtained by liver biopsy. Pediatrics, METHODS One hundred and thirteen patients suffering from chronic(More)
INTRODUCTION In patients with portal hypertension, thrombocytopenia in cirrhotics and noncirrhotics is thought to be caused by sequestration and destruction of platelets within a large spleen, suppression of platelet production in the bone marrow, and decreased activity of the hematopoietic growth factor thrombopoietin (TPO). AIM Determining the level of(More)
BACKGROUND AND STUDY AIMS Wilson disease (WD) is an autosomal recessive disorder, caused by defects in copper-transporting P-type adenosine triphosphatase (ATPase) encoded by the ATP7B gene, resulting in the deposition of copper in the liver and brain with significant disability or death if left untreated. An available regimen of treatment gives hope to(More)
BACKGROUND AND STUDY AIMS Mass compulsory HBV vaccination was applied in Egypt in 1992. The first dose of vaccine is administered at 2 months of age and routine screening of pregnant women for HBsAg is not applied. We aimed to evaluate the pattern of HBV infections after the implementation of HBV vaccination in Egyptian children. PATIENTS AND METHODS(More)
BACKGROUND AND AIM Extrahepatic portal vein obstruction (EHPVO) is an important cause of portal hypertension in children. The aim of this study was to describe the clinical presentation, possible risk factors, upper gastrointestinal endoscopic findings, and treatment modalities of children with EHPVO. METHODS After ethical approval of our study protocol(More)
Treatment of hepatitis C virus (HCV) in end-stage renal disease (ESRD) patients is an important issue before kidney transplantation (KT). The aim of the study is to assess the efficacy and tolerability of HCV treatment with pegylated interferon (PEG IFN)-α 2b in children with ESRD. The study included 17 children, aged 3-18 years with ESRD on hemodialysis(More)
