Gastroenterology Trials


Clinical research is of fundamental importance to many departments within Our Lady’s Children’s Hospital, Crumlin (OLCHC); in particular, clinical research has a very strong foundation in the Department of Gastroenterology, Hepatology and Nutrition lead by Dr. Seamus Hussey, Consultant Paediatric Gastroenterologist. Dr. Hussey dedicates his academic research time to the study of Inflammatory Bowel Disease (IBD).

The Gastroenterology department in OLCHC is the National Centre for Paediatric Gastroenterology in Ireland, therefore OLCHC is in a unique position to capture a national cohort of Children with IBD. IBD is a chronic inflammatory condition of the gastrointestinal tract and is an immune-mediated condition that comprises of Crohn’s disease (CD), ulcerative colitis (UC), and inflammatory bowel disease-unclassified (IBD-U). IBD-U is a form of colonic IBD whose diagnostic features do not allow colitis of CD or colitis of UC to be distinguished. Research surrounding IBD is of great importance as the incidence in Ireland is increasing, and this increase in mirrored in the Western world.

Clinical research in this department is carried out by Dr. Sadhbh O’Neill, Clinical Research Coordinator and Ms Alison O’Sullivan, Research Assistant. Dr O’Neill and Ms O’Sullivan progress numerous IBD research projects including DOCHAS (Determinants and Outcomes in Children and Adolescents with IBD). DOCHAS was established in January 2012 and seeks to identify and recruit all children diagnosed with IBD in Ireland. By the end of December 2017 over 750 children had been recruited to the study. Each year approximately 100 new patients are recruited to the study. The aim of the study is to determine why IBD incidence is increasing in an Irish population and to determine the outcomes for children diagnosed with IBD.

As IBD incidence is increasing world-wide we are involved in a number of international research studies which have lead sites in Israel and Canada. These studies are investigating many factors associated with IBD including the study of genetics in CD (The GEM project), the efficacy and safety of the drug Vedolizumab in a paediatric population (The VedoKids Study), the efficacy and safety of another drug Humira in a paediatric population with CD (The CAPE registry), the study of early onset IBD (the iNEOPICS study), the potential of exclusive enteral nutrition (EEN) in combination with a strict diet as an alternative to EEN alone as a treatment for CD (The Modified-EEN study) and finally two similar studies which aim to generate new indices that assess the activity of UC and CD over time. These new indices would be patient/parent reported and would assess the signs and symptoms of UC and CD (The TUMMY-UC and TUMMY-CD studies).

Clinical research is vital to the understanding of IBD and for the development of new medications to treat IBD. In OLCHC the Gastroenterology Department and the research team coordinate to allow the collection of the valuable data that will ultimately benefit patients and their parents.
