Clinical Characteristics and Risk factors of Children Suffering from Inflammatory Bowel Diseases At Assiut University Children Hospital
A retrospective and prospective, observational, non-interventional, cohort study to develop quantitative metrics from tools used as standard of care when diagnosing, assessing and monitoring patients with inflammatory bowel disease.
Abdominal pain is a common symptom in patients with inflammatory bowel disease (IBD). Up to 70 % of IBD patients experience pain when the disease is active. Even when patients with IBD are in remission, 20-50 % experience ongoing pain. The precise mechanism of developing chronic abdominal pain in patients with IBD in remission remains unknown. The aim of this study is to identify psychophysiological and biological risk factors for the development of chronic abdominal pain in patients with newly diagnosed IBD (ulcerative colitis and Crohn's disease). This study consists of 4 sections (Study 1A, 1B, 2, and 3): Study 1A: We perform a longitudinal study in 150 patients with new-onset IBD over 18 months to identify risk factors related to the brain-gut axis for the development of chronic pain. This is a collaborative study with IBD BioResourse Inception study. We administer online questionnaires, collect stool and blood samples, and record heart rate. Other physiological data collected by the Inception study will be also used for the analysis. Study 1B: This is also a collaborative study with the Inception study. We will apply for our detailed questionnaires for 7 days (as per study 1A) to be administered to all the new patients (n=450) that are included in the Inception study on a voluntary basis. Patients will be followed for 12 months. Study 2 and 3: Study 2 and 3 are a questionnaire-based cross-sectional study in patients with IBD. The participants for study 2 are patients registered in IBD BOOST study and those for study 3 are patients registered in IBD BioResource (but not in IBD Boost study). Detailed online questionnaires will be administered to them. These studies are just one-day assessment.
Vitamin D deficiency (defined as 25(OH)-vitamin D serum level <50 nmol/ l) is associated with irritable bowel disease (IBD). National guidelines recommend the administration of 800 -4000 IU cholecalciferol daily for an effective treatment, especially during the winter (poor sun exposition). Cumulative intermittent administration monthly or weekly is possible. The study aims to compare inflammation activity (primary outcome) after monthly or weekly treatment with soft capsules containing 24'000 IU cholecalciferol compared to no vitamin D supplementation. Quantification of 25(OH)-vitamin D serum values is a secondary outcome. The investigators will use newly developed soft capsules.
Periodontitis is a chronic inflammatory disease of the tooth supporting structures induced by a dysbiosis in the oral and subgingival microenvironment of susceptible patients. The long-term swallowing of high doses of periodontal pathogenic microorganisms could induce a dysbiosis of the intestinal microbiota, favouring the establishment of an 'inflamed' microbiome in terms of composition and/or function. The present project is aimed at a better understanding of the etiopathogenetic correlation between periodontitis and intestinal dysbiosis, and aims to explore the hypothesis that non-surgical periodontal treatment may reduce bacterial alpha diversity in stool samples. Fifty patients affected by stage III-IV periodontitis will be recruited, and treated by means of full-mouth scaling and root planing. Salivary and stool samples, together with a complete periodontal charting and a food diary will be collected and compared at baseline and 3 months after treatment. Age, gender and BMI-matched healthy individuals will be recruited as controls.
This is a monocentric, two-arm, non-randomised, non-blinded, historically controlled, interventional trial. The purpose of this trial is to investigate the effect of model-informed infliximab dose de-escalation on the infliximab exposure and therapeutic outcome as compared to standard dose de-escalation in patients with inflammatory bowel diseases.
Performance of diagnostic or therapeutic endoscopic procedures in inflammatory bowel disease (IBD) patients can be challenging during a viral pandemic; the main concerns being the safety and protection of patients and health care providers (HCP). The aim of this study is to identify endoscopic practice patterns and outcomes of IBD and coronavirus disease 19 (COVID-19) with a worldwide survey of HCP.
This is a prospective, two-centre, double-blind, parallel-arm, randomised, placebo-controlled trial evaluating the impact of FMT on patients with active Crohn's disease.
Inflammatory bowel disease (IBD) are lifelong chronic diseases affecting the gastrointestinal tract. The precise etiology and the different actors participating to the pathophysiological process leading to the disease development are still not well understood. A complex interaction between genetics, gut microbiota and environmental factors is thought to trigger the inappropriate mucosal immune response observed in IBD patients. We hypothesize that DON might be an environmental risk factor for IBD.The focus on the human relevance of the gut effects of DON by studying its exposure, metabolism and adverse effects in health and disease focusing on IBD patients
