Copenhagen Acute Renal Complications After Transplantations Study Group

Lung transplanted patients experience marked decrease in renal function post transplant mainly due to cyclosporine induced renal changes. Calcium channel blockers may improve renal function in cyclosporine treated transplant recipients through their effects in avoiding cyclosporine-induced renal vasoconstriction and facilitating renal sodium output. The aim of this study is to examine if calcium channel blockade administered before lung transplantation prevent cyclosporine induced nephropathy. The design is an intention to treat randomized double blinded single center study. Patients are randomized to two groups, one that received felodipine and one that receives placebo. Study population is all patients listed for lung transplantation in Denmark in the study period. Intervention is tablet felodipine titrated to 10 mg, one daily dose in 12 weeks Primary endpoint is change in renal function as measured by glomerular filtration rate using chromium-51 labeled ethylenediamine tetraacetic acid (51-Cr-EDTA) in the felodipine treated group compared with the placebo group.
