- Biomedical research profile: Immunity, Infection, and Tolerance
- Generic research profile: Innovation in Health Strategy and Quality of Care
Aim and focus
All research in the department of Gastroenterology and Hepatology is performed with the aim to increase the understanding of cellular mechanisms in (patho)physiological processes of the gastrointestinal tract and liver in order to translate this into innovations for the diagnosis and treatment in clinical gastroenterology and hepatology. The research focus is to evaluate the functional and clinical impact of (mesenchymal) stem cells and intra- and intercellular factors like Hedgehog signaling, the Bone Morphogenetic Protein pathway, glucocorticoid signalling, the lectin-complement pathway and matrix metalloproteinases on chronic inflammation, carcinogenesis, liver disease and liver transplantation.
Position in international context
The department is actively participating in several international study groups (e.g. Belgian Inflammatory Bowel Disease Research Group, European Crohn's and Colitis Organisation) and trials to explore new therapies for Inflammatory Bowel Disease, i.e. Crohn's disease and ulcerative colitis. For liver transplantation the LUMC is member of several international networks [e.g. the ELTR (European Liver Transplantation Registration)]. International collaboration on matrix metalloproteinases in inflammation and cancer is established through the International Society for Fibrinolysis and Proteolysis (ISFP). Regarding familial tumour syndromes the department of Gastroenterology and Hepatology is closely linked to the Netherlands Foundation for the Detection of Hereditary Tumours (Stichting Opsporing Erfelijke Tumoren). The organisation and the research done in this field has an excellent international reputation and it is often used by other countries to develop similar programmes. The department is heavily involved in the design and the execution of large international studies, at the level of basic research/genomics as well as at the level of clinical/translational research with (family) screening and intervention studies.
Content / highlights / achievements
The department plays a crucial role in the further development and performance of Liver Transplantation in the LUMC, with favourable clinical results. New treatment modalities with biologicals for Inflammatory Bowel Disease are introduced and evaluated, participation in research on genotype-phenotype associations is established in EU FP-6 and FP-7 programmes. The research on genetics of Colorectal Cancer has led to new internationally accepted guidelines for genetic screening of family members, the so-called Revised Bethesda Guidelines. Basic research on colorectal carcinogenesis is performed with support of NWO-Veni grants.
Research efforts will focus on the relation between genetics and inter- and intracellular mechanisms with chronic inflammation of the bowel, liver, and in liver transplantation and cancer. Close interaction between patient care and research using (national) biobank facilities provides an optimal opportunity to perform translational studies in these research areas.
Cohesion within LUMC
The research on genetics and on features of premalignant conditions of the gastrointestinal tract and liver is part of the Oncology theme in the LUMC cancer center. The liver transplantation programme is very well embedded in the broader LUMC transplantation theme. Research on liver transplantation and on chronic inflammatory conditions of the gastrointestinal tract is included in several sub-themes of the LIFI (Leiden Institute for Immunology). The research is conducted particularly in close collaboration with the departments of Surgery, Human Genetics, Pathology, Radiology and several departments participating in the LIFI.
