Ongoing Projects:

  • Complications and long-term follow-up after organ transplantation in children (several projects on patients transplanted with kidney or liver) including:

- metabolic risk factors and inflammation after kidney transplantation in children

- allergies and lung function in children with liver transplants

- motor skills and cognitive function after transplantation

- Transition: Adherence and graft loss in young people with kidney transplants

 

  • Induced pluripotent stem cells and development of organoids. Several projects developing models for the investigation of fat metabolism, cholestasis development (PNALD) and living organoids.
  • Cholestatic diseases.
  • Studies on cholestasis disease with genetic investigations and cell models
  • Early diagnosis of cholestasis and bile duct atresia
  • Pharmacokinetics in organ transplant children
  • Project investigating pharmacokinetics in children who have had a liver or kidney transplant, collaboration with Professor Anders Aasberg.
  • MitraChild: "Tacrolimus measured in capillary volumetric microsamples in pediatric patients - a cross-validation study".
  • Yotac study:

- Part 1: A feasibility study for improved adherence in adolescents by combining at-home blood microsampling for tacrolimus measurements and the medication management smart phone application.

- Part 2: The effect of self-management on adherence and other clinical outcomes in kidney- and livertransplanted adolescents.

  • Prospective review of data from the Norwegian Kidney Biopsy Register combined with data from the Norwegian Nephrology Register.
  • ABO incompatible living donor kidney transplantations in pediatric patients: a collaborative study from the Nordic Pediatric Renal Transplantation Study Group (NPRTSG)
  • "Genetic factors in children with congenital malformations in the kidneys and urinary tract" - multicenter study from Hannover

National and international multicenter studies

  • Autoimmune hepatitis in the Nordic region (Collaboration Norway, Denmark, Sweden, Finland, Estonia).
  • Acute liver failure in neonates (Collaboration Denmark, Norway, Sweden, USA)
  • Genetic cholestasis disease (Collaboration Norway, Czech Republic)
  • EVITA study - Epstein-Barr Virus Infection monitoring in kidney transplant recipients - Early identification of increased risk of infection and cancer for individualized immunosuppression. Cooperation with Odense and Aarhus, DK. Prospective multicenter study.
