BACKGROUND & AIMS Treatment of chronic hepatitis B with interferon alfa is not approved in children. The aim of this study was to evaluate the safety and efficacy of interferon alfa (IFN-alpha) in children with chronic hepatitis B and increased transaminase levels. METHODS Children were given either IFN-alpha2b (6 megaunits/m2 thrice weekly for 24 weeks)(More)
Glycogen storage disease (GSD) types I, III, and IV can be associated with severe liver disease. The possible development of hepatocellular carcinoma and/or hepatic failure make these GSDs potential candidates for liver transplantation. Early diagnosis and initiation of effective dietary therapy have dramatically improved the outcome of GSD type I by(More)
BACKGROUND & AIMS Pegylated interferon (PEG-IFN) alfa-2b plus ribavirin (RBV) is the standard of care for adults with chronic hepatitis C but was not approved for the treatment of children at the time of this study. The aim of this study was to evaluate the efficacy and safety of PEG-IFN alfa-2b plus RBV in children. METHODS Children and adolescents ages(More)
BACKGROUND Increased age at surgery has a negative impact on results of the Kasai operation for biliary atresia in infancy and early childhood. It remained unclear if an age threshold exists and if this effect persists with extended follow-up. In this study we examined the relationship between increased age at surgery and its results in adolescence. (More)
OBJECTIVE Disseminated bacillus Calmette-Guérin (BCG) infection after inoculation of live vaccine is considered to result from impaired immunity of the child. However, in half of the cases, regarded as idiopathic, no well-defined immunodeficiency condition can account for the infection. The objective of the present study is to report the prevalence,(More)
This study analyzed the results of the decentralized management of biliary atresia (BA) in France, where an improved collaboration between centers has been promoted since 1997. Results were compared to those obtained in England and Wales, where BA patients have been centralized in three designated centers since 1999. According to their birth dates, BA(More)
Lipoprotein assembly is critical for the intestinal absorption of dietary lipids and of fat-soluble vitamins. Through their inhibition of chylomicron secretion, mutations of the Sar1B gene coding for Sar1 GTPase are associated with chylomicron retention disease (CRD). The aim of this study was to describe the phenotypic expression of CRD in two clinically(More)
Anderson's disease (AD) or chylomicron retention disease (CMRD) is a rare hereditary lipid malabsorption syndrome linked to SARA2 gene mutations. We report in this study a novel mutation in two sisters for which the Sar1b protein is predicted to be truncated by 32 amino acids at its carboxyl-terminus. Because the SARA2 gene is also expressed in the muscle,(More)
BACKGROUND Infliximab (IFX) is efficacious in inducing remission in severe forms of pediatric Crohn's disease (CD). Adult studies indicate that IFX is also safe and well tolerated as maintenance therapy. The present study aimed to evaluate in a prospective manner the efficacy and safety of IFX as maintenance therapy of severe pediatric CD comparing(More)
Anderson disease (and/or chylomicron retention disease-CMRD) is a rare, autosomic recessive disorder characterized by chronic diarrhea, failure to thrive, and hypocholesterolemia in childhood. The specific molecular defect was identified in 2003 and consists of mutations in the SAR1B gene which encodes for intracellular Sar1b protein. To date, only 8(More)
