OBJECTIVE To gain insight into the molecular bases of genetically unexplained periodic fever syndromes (PFS) by screening NLRP12, a gene in which only a nonsense and a splice site mutation have so far been identified, and to assess the functional consequences of the identified missense variation. METHODS NLRP12 was screened for mutations by direct(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)
OBJECTIVES Early onset inflammatory bowel diseases (EO-IBD) developing during the first year of life are likely to reflect inherited defects in key mechanism(s) controlling intestinal homeostasis, as recently suggested for interleukin 10 (IL10). Thus, we aimed to further elaborate the hypothesis of defective anti-inflammatory responses in patients with IBD.(More)
OBJECTIVES To assess the safety of a polyethylene glycol (PEG) 4000 laxative without additional salts in pediatric patients. STUDY DESIGN This was a 3-month multicenter, randomized, double-blind, double-dummy, lactulose-controlled, parallel study enrolling 96 ambulatory constipated children aged 6 months to 3 years, treated daily with 4-8 g PEG or 3.33(More)
BACKGROUND & AIMS Oral rehydration therapy is the only treatment recommended by the World Health Organization in acute diarrhea in children. Antisecretory drugs available could not be used because of their side effects, except for racecadotril, which is efficient in acute diarrhea in adults. METHODS The efficacy and tolerability of racecadotril (1.5 mg/kg(More)
BACKGROUND Congenital esophageal stenosis (CES) is a rare condition frequently associated with esophageal atresia (EA). There are limited data from small series about the presentation, treatment, and outcomes of CES. METHODS Medical records of all patients with CES included in the French Network on Esophageal Malformations and Congenital Diseases were(More)
BACKGROUND Anderson's disease (AD) or chylomicron retention disease (CMRD) is a very rare hereditary lipid malabsorption syndrome. In order to discover novel mutations in the SAR1B gene and to evaluate the expression, as compared to healthy subjects, of the Sar1 gene and protein paralogues in the intestine, we investigated three previously undescribed(More)
UNLABELLED Hypervitaminosis A is an unusual cause of infant hypercalcemia. The way it occurs can be very surprising, as one can notice from the following case report. CASE REPORTS A three-year-old boy, presenting important behavioral disorders, was hospitalized because of a deterioration of his general state of health associated with vomiting, cephalgias,(More)
Infliximab, a monoclonal antibody against tumor necrosis factor-alpha, has been shown to be effective for the treatment of refractory Crohn's disease in adult patients, but experience in pediatrics is limited. This retrospective study included 88 children and adolescents, 39 girls and 49 boys, with a median age of 14 years (range 3.3-17.9). Infliximab was(More)
Defensins, endogenous antibiotic peptides, are part of the intestinal epithelial barrier. In this pilot study we analyzed the possibility of measuring fecal beta-defensin-2 (HBD2) in comparing inflammatory and noninflammatory conditions. In samples from healthy control individuals, low levels of HBD2 were detectable, which markedly rose under inflammatory(More)
