EFFECT OF THERAPY WITH DEFLAZACORT ON DYSLIPOPROTEINEMIA AFTER PEDIATRIC RENAL-TRANSPLANTATION

Deflazacort is an oxazolone compound derived from prednisolone, with s imilar immunosuppressive action but fewer side effects. Kidney functio n, weight/height ratio, serum triglycerides, cholesterol, high-density lipoprotein (HDL) cholesterol, very-low-density lipoprotein cholester ol, low-density lipoprotein (LDL) cholesterol, apolipoprotein A, apoli poprotein B, and lipoprotein (a) were studied before and 6 months afte r substitution of deflazacort (mean +/- SEM, 0.3 +/- 0.1 mg/kg per day ) for methylprednisone (0.2 +/- 0.1 mg/kg per day) in 14 patients trea ted with cyclosporine, aged 3.1 to 20.3 years, 3 years after renal tra nsplantation. Serum creatinine and calculated creatinine clearance did not change significantly, and weight/height ratio decreased from 20.0 % +/- 7.1% to 12.5% +/- 6.5% (P < .005) during deflazacort therapy. To tal cholesterol was reduced by 15.9% (from 233 +/- 15 mg/dL to 196 +/- 13 mg/dL, P < .01), LDL cholesterol by 25.5% (from 153 +/- 14 mg/dL t o 114 +/- 12 mg/dL, P < .01), and TC/HDL cholesterol ratio by 28.3% (f rom 5.3 +/- 0.4 to 3.8 +/- 0.4, P < .01), whereas HDL cholesterol incr eased 18% (from 45 +/- 2 mg/dL to 53 +/- 2 mg/dL) and apolipoprotein A by 8.3% (from 122 +/- 5 mg/dL to 132 +/- 5 mg/dL, P < .05) during def lazacort therapy. Our data suggest that substituting deflazacort for m aintenance methylprednisone therapy leads to an improvement in the lip oprotein profile of children after renal transplantation.
