Research goals and strategy
PELIKANTRA was created in 2011 with members from several sections at the Department of Pediatrics at Oslo University Hospital. We are working with gastroenterology, nutrition, nephrology, hepatology, and organ transplantation. Our research is conducted both at Department of Pediatrics at Ullevål and Rikshospitalet and at Department of Pediatric Research. We are cooperating with several research groups. PELIKANTRA does both clinical science and basic science and takes a special interest in putting clinical relevant projects into the laboratory. Several of the projects relate to the life after organ transplantation. Other areas of interest are inflammatory bowel disease, enteral and parenteral nutrition, and cholestasis.
Current research projects
- IBSEN-II (Inflammatory Bowel South Eastern Norway-II): Children and adolescents presenting with inflammatory bowel disease was included in 2005-2007. We are studying clinical presentation, biochemical markers, and biopsies at diagnosis and after 2 years of treatment.
- EARLY-IBD: Prospective international multicenter study of presentation of inflammatory bowel disease.
- Transplantation and allergy: There are several reports of increased incidence of allergy in liver transplanted children. We are investigating how liver transplanted children are affected by different allergies and whether allergies are associated with certain risk factors.
- Hypoxic hepatocyte damage: In the transplanted liver thrombosis of the hepatic artery may cause hypoxic-ischemic damage of the liver. We are investigating mechanisms of hypoxic-ischemic hepatocyte damage and how pharmacological treatment can affect the extent of hypoxic-ischemic hepatocyte damage. A model with combined oxygen and glucose deprivation in hepatocytes is used. Another field of interest is development and mechanisms of cholestasis and hepatobiliary transport systems are investigated in hepatocytes.
- Fecal calprotectin: Fecal calprotectin is a marker of inflammatory activity in inflammatory bowel disease. Several parallel methods of analysis of calprotectin exist and we compare and relate different methods to endoscopic findings in children with and without inflammatory bowel disease.
