Cyclosporin-A in the treatment of nephrotic syndrome: the importance of monitoring C0 (trough) and C2 (two hours after its administration) blood levels.

Cyclosporin-A (CsA) is often used in the treatment of nephrotic syndrome. The effectiveness of CsA and the value of C2 blood levels in the treatment of nephrotic syndrome, due to various glomerular diseases, were studied. Forty-two nephrotic patients (M/F 21/21), with well-preserved renal function (creatinine clearance 87+/-20 ml/min) were included in the study.
