BACKGROUND Robust evaluation of induction therapies using both clinical and inflammatory outcomes in pediatric Crohn's disease (CD) are sparse. We attempted to evaluate clinical, inflammatory, and composite outcomes of induction of remission therapies (normal C reactive protein [CRP] remission) in a large pediatric prospective multicenter study. METHODS(More)
BACKGROUND AND AIMS The commensal microbiota of the gastrointestinal tract plays an important role in the pathogenesis of inflammatory bowel disease. We examined the horizontal structure of the fecal microbiota in the colon in adolescents with Crohn disease or ulcerative colitis and a control group. PATIENTS AND METHODS Fecal samples were collected in 3(More)
BACKGROUND AND AIM Exclusive enteral nutrition (EEN) is an effective method of treatment in achieving remission in inflammatory bowel disease (IBD); however, its mechanism of action is still poorly understood. The objective of our study was to assess the influence of EEN on serum vascular endothelial growth factor (VEGF) and transforming growth factor-beta(More)
BACKGROUND Definitive diagnosis of pediatric ulcerative colitis (UC) may be particularly challenging since isolated colitis with overlapping features is common in pediatric Crohn's disease (CD), while atypical phenotypes of UC are not uncommon. The Paris classification allows more accurate phenotyping of atypical inflammatory bowel disease (IBD) patients.(More)
Evidence supporting the importance of assessment of mucosal healing in inflammatory bowel disease has increased in the last years. Mucosal healing has been integrated in the assessment of treatment efficacy in ulcerative colitis, but in Crohn's disease this thought has arised after biological agents have been evaluated in clinical trials. Although a(More)
ABSTRACT: Prophylactic treatment with ovine surfactant was evaluated in preterm lambs at risk for development of hyaline membrane disease. Eight mechanically ventilated newborn lambs were treated before delivery and 10 served as controls (gestational age 129–131 d). Lung mechanics, functional residual capacity, alveolar ventilation, efficiency of(More)
OBJECTIVES While magnetic resonance enterography (MRE) can accurately reflect ileal inflammation in pediatric Crohn's disease (CD), there are no pediatric data on the accuracy of MRE to detect upper gastrointestinal tract (UGI) lesions. We aimed to compare MRE and esophagogastroduodenoscopy (EGD) in detecting the spectrum and severity of UGI disease in(More)
BACKGROUND The combination of the severity of pediatric-onset inflammatory bowel disease (IBD) phenotypes and the need for intense medical treatment may increase the risk of malignancy and mortality, but evidence regarding the extent of the problem is scarce. Therefore, the Porto Pediatric IBD working group of ESPGHAN conducted a multinational-based survey(More)
Gastroesophageal reflux (GER) is considered to be one of the triggering factors of asthma attacks. It is believed that theophylline (TE) exacerbates GER occurrence. To evaluate the influence of TE on GER intensity in asthmatics we examined 10 stable asthmatic children aged from 3 to 11 yrs, before and during TE treatment within therapeutical TE serum range.(More)
ABSTRACT: To determine the influence of an altered carotid body function on the laryngeal chemoreflex (LCR) response, reflex apnea was induced by laryngeal water stimulation during normoxia or acute hypoxia in unanesthetized awake lambs in which the ventilatory response to acute hypoxia was attenuated by prolonged postnatal hypoxemia. Prolonged hypoxemia(More)
