Nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) are common in children and adolescents. However, standard histological criteria for pediatric NAFLD and NASH are undeveloped. We reviewed consecutive patients ages 2 to 18 years with biopsy-proven NAFLD diagnosed between 1997 and 2003. Biopsies were evaluated by two(More)
OBJECTIVE To describe the clinical characteristics of nonalcoholic fatty liver disease (NAFLD) in children, including insulin resistance, and to test for correlation with liver pathology. STUDY DESIGN A retrospective review of children with biopsy-proven NAFLD at Children's Hospital San Diego from 1999 to 2002. Liver biopsy specimens were independently(More)
BACKGROUND & AIMS Congenital tufting enteropathy (CTE) is a rare autosomal recessive diarrheal disorder presenting in the neonatal period. CTE is characterized by intestinal epithelial cell dysplasia leading to severe malabsorption and significant morbidity and mortality. The pathogenesis and genetics of this disorder are not well understood. The objective(More)
BACKGROUND Eosinophilic esophagitis (EE) is a disorder characterized typically by pan-esophageal eosinophilia. We evaluate a palatable, long-acting topical corticosteroid preparation for the treatment of EE. STUDY DESIGN This is a retrospective analysis of symptoms, endoscopic and histologic findings, efficacy, and safety of treatment in children with EE(More)
OBJECTIVES Cysteamine prevents organ damage in children with cystinosis, but may cause gastrointestinal (GI) symptoms. In this study we evaluated the nature of GI disease, and the value of omeprazole in controlling GI symptoms in these children. STUDY DESIGN Upper GI disease was evaluated with endoscopy, gastrin levels, and acid secretion studies after(More)
BACKGROUND & AIMS Eosinophilic esophagitis (EoE) is caused by immunologic reactions to ingested/inhaled allergens. The diagnosis is considered if >or=15 eosinophils per high-powered field (eos/hpf) are detected in mucosal biopsies. Placebo-controlled studies have not been conducted to evaluate the safety and efficacy of oral viscous budesonide (OVB). (More)
Oral cysteamine therapy prevents natural disease progression in children with cystinosis, but it may cause severe gastrointestinal (GI) symptoms through gastric acid-hypersecretion. The purpose of this study was to assess the value of esomeprazole in controlling cysteamine-induced acid-hypersecretion and GI symptoms in children with cystinosis. Subjects(More)
BACKGROUND Esophageal remodeling occurs in eosinophilic esophagitis (EE) patients but whether the components of remodeling in the subepithelium are reversible by administration of topical oral corticosteroids is unknown. METHODS We quantitated the degree of lamina propria remodeling in esophageal biopsies obtained before and after at least 3 months of(More)
BACKGROUND Eosinophils are associated with airway remodeling in asthma, but studies have not yet determined whether eosinophilic esophagitis (EE) is associated with esophageal remodeling. OBJECTIVE We performed quantitative immunohistochemical analysis of remodeling changes in esophageal biopsy specimens from children with and without EE to evaluate if(More)
