Kidney Transplantation

The group initiates and participates in studies focusing on renal transplant patients. The research is clinically oriented towards these patients.

About the group

The research group carries out epidemiological and clinical outcome studies in kidney transplantation, pancreas transplantation and islet transplantation.

Data from the Norwegian Renal Registry (which is updated yearly) together with data from a local biobank are generated, together with RCTs and observational studies.

The studies focus on immunotherapy, pharmacokinetics, pharmacotherapeutic modelling and metabolism, in particular metabolism in post-transplant diabetes (PTDM).

Clinical studies are oriented on outcomes and complications after kidney and pancreas transplantation including epidemiological studies, RCT’s and explanatory studies of mechanisms and pathogenesis.

The studies include immunotherapy and pharmacokinetics and pharmacotherapeutic modelling. For epidemiological studies local biobank and follow up via Norwegian Renal Registry are essential.
