    ABSTRACT: Cyclosporine (CyA) monitoring with postabsorptive levels can predict the risk of an acute rejection episode (ARE). Large doses of CyA are needed to obtain adequate drug exposure. The impact of this strategy on renal function, especially in patients with delayed graft function (DGF), is unknown. We report our experience comparing C3 (3-hour postdose) monitoring with a historical series of cadaveric renal transplants. Sixty-three consecutive patients who received cadaveric renal transplants were followed for 1 year. Group A (historical n = 31) patients received 6 mg/kg/d CyA with the dose adjusted according to the trough level (target, 250-350 ng/mL), group B (study n = 32) received 10 mg/kg/d CyA with dose adjustments based upon C3 (target, 1100-1500 ng/mL). All patients received cyclosporine prednisone and a third agents. The general characteristics of the donors and recipients were comparable. The incidence of biopsy-proven ARE at 1 year in group A was 42% and 19% in group B (P <.05). Patients achieving C3 levels >1000 ng/mL at 1 week displayed significantly lower ARE rates (8% vs 50%; P <.05). The rate of DGF was similar in both groups, but the duration was longer in group B (15 vs 21 days, P <.05). The serum creatinine (SCr) level was significantly higher in group B at 3 months (1.47 mg/dL group A vs 1.76 mg/dL group B; P <.05). Patients in group B with DGF showed significantly higher SCr values at 1 year (1.18mg% vs 2.03 mg%; P <.05). C3 level monitoring of CyA yields excellent results in terms of decreased ARE, but an increased SCR was observed among patients with DGF.
