Show moreIn chapters 2, 3 and 4, novel biomarkers IGFPB7, TIMP-2 and long noncoding RNAs were studied in order to find new diagnostic possibilities for early recognition and diagnosis of injury in native and transplanted kidneys. In chapter 2, diabetic nephropathy was found to be associated with higher levels of circulating TIMP-2, which did not normalize after simultaneous pancreas-kidney transplantation. In chapter 3, we found that four circulating long noncoding RNAs associated with diabetic nephropathy and did normalize after simultaneous pancreas-kidney transplantation. In chapter 4, acute rejection in kidney transplant recipients resulted in higher circulating LNC-EPHA6 levels. In chapter 5, clinical parameters and single antigen bead assay for measurement of donor specific antibodies were evaluated in the context of antibody-mediated rejection. Female recipients who received a kidney transplant from their spouse were especially at risk for acute antibody-mediated rejection and a single antigen bead assay is more sensitive to detect antibodies in this group than the standard diagnostic strategy. In chapter 6, mesenchymal stromal cell therapy is studied in a randomized controlled trial to evaluate the potential for prevention of acute rejection and fibrosis in transplanted kidneys. MSC therapy resulted in similar fibrosis scores and rejection rates. Show less
