TransplantLines Insulin Resistance and Inflammation Biobank and Cohort Study

Death, Death, Cardiac, Diabetes, Graft Failure

Short-term (1-year) results of renal transplantation are now excellent (over 95%). Long-term (10-year and longer) results are, however, still disappointing. Where most research has focused on immunosuppression and infections, the investigators hypothesize that in renal transplant recipient, amongst others overweight, obesity, chronic use of immunosuppressive drugs and impaired renal function contribute to insulin resistance and chronic low-grade inflammation, which pose the renal transplant recipients at increased risk for cardiovascular disease, decline of function of the transplanted kidney and other complications, including post-transplant diabetes. This study is a biobank and cohort study which investigates this hypothesis.

To investigate this hypothesis we have detailedly phenotyped 606 renal transplant recipients who at the time of inclusion all were one year or more after transplantation, therewith providing a representation of stable outpatient renal trannsplant recipients late after renal transplantation. At the time of these baseline measurements, we also created a biobank with plasma, serum and aliquots of 24h urine collections. Beyond baseline, we have a regular update on adverse events, including all-cause mortality, cause-specific mortality, graft failure and development of new-onset diabetes after transplantation (NODAT).
