However, there are few data on HCV genotype 4 (HCV-4) infection. We evaluated, in a unique well-characterized cohort of HCV-4 patients, the association of IL28B polymorphism with response to treatment or liver disease severity.\n\nMethods: This study included 164 HCV-4 patients from different ethnic groups (Egyptian, European, Ispinesib cell line and Sub-Saharan African). Among these patients, 82 were studied for response and 160 for disease severity. Free DNA extracted from all the 164 patient’s

serum samples was analyzed by direct sequencing of the SNP rs12979860 of IL28B. Genetic and bio-clinical features from patients having sustained virological response (43 SVR patients) and from those who did not respond to treatment or had a relapse after the end of the treatment (39 NR patients) were compared. IL28B polymorphism

was compared between the 78 patients with mild fibrosis (Metavir score F0-F1) and the 82 with advanced fibrosis Etomoxir cost (F2-F4).\n\nResults: Our data showed a better treatment response rate of the C allele of the IL28B gene SNP rs12979860 (p = 0.0008). The response rates were 81.8%, 46.5%, and 29.4% for genotype CC, CT, and TT, respectively. No significant relationship was found between rs12979860 and the severity of the disease.\n\nConclusions: The SNP rs12979860 is strongly associated with SVR in patients infected with HCV-4, but not with liver disease severity. Analysis of IL28B genotype might

be used to guide treatment for these patients. (C) 2011 European Association for the Study of the Liver. Published by Elsevier B.V. All rights reserved.”
“Background/aims: The use of immunoglobulin G and A anti-gliadin antibodies for celiac disease screening has decreased due to higher specificity and sensitivity of tissue transglutaminase and endomysial antibodies. Greater values of immunoglobulin-A anti-gliadin antibody have been associated with more severe mucosal damage in proven and probable celiac disease patients. The aim of this study was to determine whether anti-gliadin antibody immunoglobulin A has any clinical importance in diagnosing celiac disease in children. Children with a chronic history selleck chemicals of vomiting, abdominal pain, diarrhea, or constipation in the outpatient clinic were evaluated for celiac disease. Materials and Methods: Tissue transglutaminase and anti-gliadin antibody immunoglobulin A in serum were determined by ELISA test and endomysial antibodies immunoglobulin A by indirect immunofluorescence. Most of these children with isolated positive anti-gliadin antibody immunoglobulin A were further evaluated by performing proximal gastrointestinal biopsies. Results: Sixteen children had isolated positive anti-gliadin antibody immunoglobulin A (negative tissue transglutaminase and endomysial antibodies immunoglobulin A). Eight were male (mean age: 9.7 years).
