C2 monitoring of cyclosporine in stable renal transplant patients results in lower costs and improved renal function.

Abstract:

INTRODUCTION:C2 (2-hour post-absorption levels) monitoring of cyclosporine (CsA) seems to reduce the rate of acute rejection episodes (ARE) without increasing nephrotoxicity during the first months after transplant. There are a few reports on the impact of adopting this strategy in patients with stable renal transplants. We herein report a prospective trial in long-term renal transplant patients (>6 months) monitored by C0 or C3 who were switched to C2 monitoring. METHODS:Seventy-six (mean age = 43 +/- 11 years) kidney transplant patients (mean = 37 +/- 21 months after transplant) receiving CsA, steroids, and azathioprine were switched to C2 monitoring, seeking to achieve a target range of 800 +/- 100 ng/mL. The patients were followed for at least 6 months. RESULTS:At conversion the C2 values of 61% of the patients were above and 17% below the therapeutic range. Six months after conversion there was a significant reduction in BUN (29 +/- 11 vs 27 +/- 10, P < .01), Creatinine (Cr), cholesterol, and triglyceride levels were unchanged. Mean CsA dose was decreased 10% from 244 +/- 63 to 220 +/- 52 (P < .01), implying a net savings of 390 US dollars per patient per year. Among the group of patients who showed a high C2 level, there was also a reduction in BUN (30 +/- 12 vs 27 +/- 10, P < .01) and a nonsignificant decrease in Cr (1.53 +/- 0.6 vs 1.50 +/- 0.6). CONCLUSIONS:C2 monitoring in stable kidney transplant recipients is feasible and safe. The strategy results in reduced drug costs and improved renal function.
