Abstract:
:Cyclosporine (CyA) has an immunosuppressive effect that might suggest a therapeutic role in idiopathic glomerular conditions. We focused on the optimization of CyA treatment control in patients with idiopathic nephrotic syndrome by using trough-level CyA measurements (C0) and the 2-h postdose levels (C2). Twenty-two patients (14 male, 8 female) with idiopathic nephrotic syndrome and the mean age of 51 +/- 18 months (mean [M] +/- standard deviation [SD]) were enrolled in our study during a period of 10 months (range: 3-18 months). All of the patients received CyA (2-3 mg/kg) in combination with methylprednisolone. In the present study protocol CyA concentrations (C0, C2), renal function, lipid profile, and degree of proteinuria were determined. The mean proteinuria of our patients before treatment was 11 972 +/- 7953 mg/24 H (+/-SD) and the mean creatinine level (Cr) was 0.99 +/- 0.37 mg/dL (+/-SD). Proteinuria decreased significantly already from the first month of therapy with CyA to 3578 +/- 2470 mg/24 H (M+/- SD), and during the whole study period this reduction was significant (0.56 +/- 0.37 gr/24 H (M +/- SD), P < 0.05). At the same time renal function preserved, 1.09 +/- 0.48 mg/dL (M +/- SD). The blood levels of C0 were 135.10 +/- 97.36 ng/mL (M +/- SD) and the blood levels of C2 were 725 +/- 256 ng/mL (M +/- SD) at the first month of therapy. At the same time renal function preserved, 1.09 +/- 0.48 mg/dL (M +/- SD). Total cholesterol levels reduced significantly during study period (276.89 +/- 45.57 to 200.67 +/- 40.27 mg/dL [M +/- SD]). The mean number of antihypertensive medication remained the same. The whole therapeutic protocol did not provoke any kind of side effects and CyA was quite tolerated by our patients. Treatment of idiopathic nephrotic syndrome with low doses of CyA with methylprednisolone leads to remission of proteinuria without deterioration of renal function. Blood levels of C0 for monitoring and treatment of nephrotic syndrome agrees with recent literature, while our study focus on establishing the proper levels of C2 for the treatment of nephrotic syndrome. The efficacy of CyA is combined with safety and tolerance.
