OBJECTIVES: To determine prospectively the temporal variations of cyclosporine-A lymphocyte maximum level, whole blood maximum concentration, and total lymphocyte count in patients with de novo kidney transplantation. MATERIALS AND METHODS: Lymphocyte maximum level, whole blood maximum concentration, and total lymphocyte count were prospectively measured in 35 patients at 1, 2, and 3 months after kidney transplantation. Two groups--a biopsy-proven acute rejection group (REJ+) and a rejection-free group (REJ-)--were compared. RESULTS: Both groups had similar lymphocyte maximum levels, whole blood maximum concentrations, and total lymphocyte counts at the first month after transplantation. REJ+ patients had significantly lower lymphocyte maximum levels at 2 and 3 months (59+/-34 and 33+/-9 pg/Lc) and higher total lymphocyte counts (0.00204+/-0.00078x10(9)/L and 0.00203+/-0.00022x10(9)/L) when compared with their REJ- counterparts (87+/-56 and 63+/-30 pg/Lc, P<.05 and P<.007) and (0.00137+/-0.00074x10(9)/L and 0.0015+/-0.0006x10(9)/L, P<.02 and P<.003) respectively. Whole blood maximum concentrations were significantly higher in patients in the REJ+ group (2050+/-623 vs 1414+/-536 ng/mL, P<.02) at 2 months. At 3 months, the 2 groups were comparable (1158+/-340 vs 1365+/-525 ng/mL, P=NS). CONCLUSIONS: These results suggest that acute rejection is associated with a relatively low cyclosporine- A lymphocyte maximum level and high total lymphocyte count in the early posttransplant period. Cyclosporine-A whole blood maximum concentration failed to correlate with clinical outcome. Cyclosporine-A lymphocyte maximum level seems to offer a more reliable alternative than does whole blood maximum concentration for cyclosporine-A monitoring in patients with kidney transplantation.
