BACKGROUND Celiac disease (CD) may be associated with other immunologic disorders in adults and children. Previous studies linking CD and autoimmune thyroid disease in children have included very few patients with limited biochemical and immunologic screening tests. The aim of this multicenter study was to establish the prevalence of autoimmune thyroid(More)
BACKGROUND AND OBJECTIVES Total parenteral nutrition (TPN) is a lifesaving therapy in children with intestinal failure, frequently complicated by liver dysfunction. Plant sterols (phytosterols) of lipid emulsions have been supposed to contribute to cholestasis in TPN-treated children. The present study aimed to evaluate the plasma and red blood cell(More)
Azathioprine is a thiopurine immunosuppressive antimetabolite used to chronically treat inflammatory bowel disease and autoimmune hepatitis. Azathioprine treatment is a long-term therapy and therefore it is at risk for non-adherence, which is considered an important determinant of treatment inefficacy. Measurement of 6-thioguanine and 6-methylmercaptopurine(More)
We describe the prevalence and nature of gastrointestinal (GI) symptoms in 58 children affected by cerebral palsy (range: from 6 months to 12 years of age) referred to a pediatric neurology outpatient clinic. In each patient we assessed (GI) symptoms and defined the associated GI functional or structural abnormalities. Furthermore, we tried to correlate the(More)
Although supraphysiological concentrations of urea are known to increase oxidative stress in cultured cells, it is generally thought that the elevated levels of urea in chronic renal failure patients have negligible toxicity. We previously demonstrated that ROS increase intracellular protein modification by O-linked beta-N-acetylglucosamine (O-GlcNAc), and(More)
OBJECTIVE Deranged gastric motility and delayed gastric emptying are commonly implicated in the pathophysiology of gastroesophageal reflux disease. We measured gastric electrical activity and gastric emptying time of a solid-liquid meal by electrogastrography and antral ultrasound, respectively, in 42 patients with gastroesophageal reflux disease (age 7.4(More)
Prolonged recordings of esophageal motility have shown that dynamic changes of lower esophageal sphincter (LES) pressure such as transient LES relaxation and LES pressure drifts are the most common mechanisms underlying gastroesophageal reflux (GER). The coexistence of a delayed gastric emptying has also been reported in a high proportion of patients with(More)
Thirty two consecutive patients (age range 6 months-13.4 years) with severe reflux oesophagitis were randomised to a therapeutic trial for eight weeks during which they received either standard doses of omeprazole (40 mg/day/1.73 m2 surface area) or high doses of ranitidine (20 mg/kg/day). Twenty five patients completed the trial (12 on omeprazole, 13 on(More)
OBJECTIVES The aim of the study was to evaluate, in 42 children with gastroesophageal reflux disease, the predictive value of both esophageal manometry and gastroesophageal intraluminal pH on the responsiveness of the disease to medical therapy. METHODS Motility of lower esophageal sphincter and esophageal body was carried out through a perfused pediatric(More)
BACKGROUND Whole gut lavage is currently used as preparation before radiological or endoscopic examination of the large bowel. AIM To validate the gut lavage technique for the assessment of mucosal inflammation, by measuring intestinal IgG and interleukin 1 beta (IL-1 beta) in the fluid obtained. PATIENTS Sixteen children with Crohn's disease (CD), 14(More)
