Measurement of Basal Metabolism in Patients With Crohn's Disease and Ulcerative Colitis and Correlation With Disease Activity.
This multicenter prospective observational non-pharmacological study aims to evaluate resting energy expenditure (REE) in pediatric patients affected by inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis. REE will be measured using indirect calorimetry and estimated using predictive equations. The study also aims to investigate the relationship between REE, disease activity, and dietary or pharmacological treatments. Clinical, laboratory, anthropometric, nutritional, and disease activity data will be collected during routine clinical follow-up at diagnosis, after induction therapy, and during follow-up visits.
• Pediatric patients aged 6 to 17 years
• New diagnosis of inflammatory bowel disease, including Crohn disease or ulcerative colitis, according to ECCO/ESPGHAN criteria
• Written informed consent signed by parents or legal guardians
