Biomarkers to Predict and Monitor Response to Infliximab
The aim of the study is to generate novel minimally-invasive serum protein signatures and biomarkers in children and adolescents with Crohn's Disease (CD) that correlate with and can predict and monitor patients who will have a prolonged response to Infliximab so that personalized medicine can be applied to patients with CD.

Boosting Biologics in UC
This study evaluates the safety of the probiotic compound IDOFORM TRAVEL® in patients with ulcerative colitis undergoing anti-TNF treatment with insufficient clinical response. Furthermore, the study aims to explore the composition of the bacteria of the gut as well as the immunological activity in patients with ulcerative colitis undergoing anti-TNF treatment, aiming to identify differences between groups of patients responding and not responding adequately to treatment. The project will explore whether probiotics have beneficial effects as adjuvant therapy in ulcerative colitis patients with insufficient response to anti-TNF...

Calcium Supplements Strategy for Kidney Stones Prevention in Crohn's Patients
Hospitalization for kidney stones in the Inflammatory Bowel Disease (IBD) population is common, particularly among Crohn's patients who had a small bowel resection. This patient population experiences a lifetime occurrence of kidney stone formation as high as 25% accompanied with a high rate of recurrence (the typical rate of stone formation is ~10% in the non IBD population). Giving oral calcium is used to bind oxalate in the intestine in an attempt to reduce the amount of oxalate that is absorbed into the body and to reduce urinary oxalate levels. However, there are no defined guidelines for the optimum dosing of calcium. This...

Can Vitamin D Supplementation in People With Crohn's Disease Improve Symptoms as an Adjunct Therapy?
There are around 115,000 people in the United Kingdom suffering with Crohn's Disease (CD). CD can cause inflammation and ulcers to develop anywhere within the gut. Symptoms of the disease include diarrhoea, abdominal pain and nutritional problems including vitamin D deficiency. Around half of people with CD are likely to have vitamin D deficiency. Research has shown that treating vitamin D deficiency in people with CD might help to improve the symptoms of the disease. However, there are no clear guidelines on how to detect or treat vitamin D deficiency in people with CD. There will be two parts to the planned research involving...

Capsule Colonoscopy in Crohn's Disease and Its Correlation With Conventional Colonoscopy and Faecal Calprotectin
Aims: - To study the feasibility of capsule colonoscopy in patients with Crohn's Disease (CD). - To compare the results of capsule colonoscopy with conventional colonoscopy in assessing mucosal healing. - To correlate the level of faecal calprotectin with the results of capsule colonoscopy and conventional colonoscopy. - To document changes in clinical practice attributable to the capsule colonoscopy findings a) concordant with and b) in addition to the parallel findings at colonoscopy and ileoscopy. Project design: Cross sectional, prospective, comparative study ...

Capsulized Fecal Microbiota Transplantation in Pediatric Ulcerative Colitis Patients
Fecal Microbiota Transplantation(FMT) - reconstitution of normal flora by a stool transplant from a healthy individual, is increasingly being recognized as a therapeutic modality for diseases that are associated with gut dysbiosis. This is a placebo-controlled, double blinded interventional study evaluating multiple, oral, fecal microbiota transplantation, administered in newly diagnosed pediatric patients with mild-moderate UC. The primary objective is to assess the safety and feasibility of multiple, oral, fecal microbiota transplantation, in newly diagnosed pediatric patients with mild-moderate UC. All processing will...

Clinical and Basic Investigations Into Hermansky-Pudlak Syndrome
Hermansky-Pudlak Syndrome (HPS) is an inherited disease which results in decreased pigmentation (oculocutaneous albinism), bleeding problems due to a platelet abnormality (platelet storage pool defect), and storage of an abnormal fat-protein compound (lysosomal accumulation of ceroid lipofuscin). The disease can cause poor functioning of the lungs, intestine, kidneys, or heart. The major complication of the disease is pulmonary fibrosis and typically causes death in patients ages 40 - 50 years old. The disorder is common in Puerto Rico, where many of the clinical research studies on the disease have been conducted. Neither the full...

COLISURG Prospective, Multicentric Cohort
The surgical treatment of the ulcerative colitis (UC) remains associate to a significant morbidity (up to 60%). Anastomotic fistula and pelvic sepsis are the most severe complications which could dramatically compromise the surgical issue and functional status. Thanks to the current therapeutic arsenal and the evolution of health care paradigms, the quality of life of patients plays a key role in the modern global management of these medical conditions. Biotherapies (e.g anti-TNF) are widely used to treat patients with UC. Anti-TNF and anti-integrins have an effect on the immune response and can theoretically aggravate the infectious...

COlonic Salvage by Therapeutic Appendectomy.
Rationale: The annual incidence of ulcerative colitis (UC) amounts to 6-8 new cases per 100.000. Patients are initially treated medically, and colitis refractory to medical management is treated surgically, mostly by means of an (emergency) colectomy or a proctocolectomy with ileal J-pouch anastomosis. Over the past 10 years evidence has been accumulating indicating that the appendix has an immunomodulatory role in patients with UC reducing the need for medication and perhaps even colectomy. Objective: The objective of this prospective observational cohort study is to evaluate the effect of appendectomy on the disease course of...
