Abstract

Study Objective. To evaluate the utility of cyclosporine (CsA) trough concentrations as a monitoring tool for acute graft rejections and CsA nephrotoxicity. Design. Retrospective chart review. Setting. University- affiliated teaching hospital. Patients. One hundred thirty-seven adults who had undergone kidney transplantation. Measurements and Main Results. Clinical data extracted from the charts were CsA dosage, CsA trough levels (whole blood, HPLC method), biopsy findings to confirm acute rejections, and serum creatine to determine clearance by the Jelliffe method. Data were collected at up to 1 month, between i month and 3 months, and between 3 and 12 months after transplantation. For each time period, receiver's operating characteristics curves were generated to identify the optimum CsA concentration for avoiding acute rejection and CsA nephrotoxicity. At up to 1 month, the CsA therapeutic response threshold was 182 ng/ml (sensitivity 69%, specificity 84%, p0.1) and the toxicity threshold for CsA nephrotoxicity remained relatively static at 204 ng/ml (sensitivity 100%, specificity 14%, p
