Deflazacort is an oxazoline compound derived from prednisolone with similar antiinflammatory effects but fewer side effects. We studied changes in kidney function, growth velocity, weight/height ratio, and growth hormone secretion before and a year after substitution of deflazacort for methylprednisone in nine patients aged 9 to 15 years, 4 years after renal transplantation; all were in Tanner pubertal stage 1. Methylprednisone (mean +/- SEM: 0.2 +/- 0.02 mg/kg per day) was replaced by deflazacort (0.3 +/- 0.03 mg/kg per day) for a mean period of 15 months. Serum creatinine and calculated creatinine clearance did not change significantly during deflazacort treatment. Growth velocity increased from 1.5 +/- 0.3 to 3.2 +/- 0.5 cm/yr (p < 0.005) in the nine patients. Weight/height ratio decreased from 28.4% +/- 8.5% to 16% +/- 6.7% (p < 0.005). Cushingoid appearance decreased in all patients. Mean spontaneous growth hormone secretion increased from 2.5 +/- 0.4 to 4.4 +/- 1.2 ng/ml (p < 0.05). Our findings indicate that immunosuppressive treatment with deflazacort is as effective as methylprednisone and is associated with fewer side effects.

Deflazacort is an oxazoline compound derived from prednisolone. We studied changes in kidney function, growth velocity, weight/height ratio, insulin-like growth factor (IGF-I), and IGF binding proteins before and after substitution of deflazacort for methylprednisone in 27 transplanted patients aged 3.1-20 years. Methylprednisone (mean +/- SEM 0.17 +/- 0.01 mg/kg per day) was replaced by deflazacort (0.29 +/- 0.01 mg/kg per day) for a period of 1-5 years. Calculated creatinine clearance did not change significantly during deflazacort treatment. Growth velocity increased from 2.6 +/- 0.5 cm/year to 5.2 +/- 0.7 cm/year (1st year) in 14 prepubertal patients. After 4 years of deflazacort treatment, height standard deviation score for chronological age did not change in 7 prepubertal patients. Mean weight/height ratio decreased by 50% (1st year) and remained reduced during follow-up. Serum IGF-I, IGF binding protein-3 (IGFBP3), IGF/IGFBP3 molar ratio, and IGF-I and II binding capacities showed no significant change; however in 5 of 6 patients IGFBP2 decreased during deflazacort therapy. Our findings suggest that immunosuppressive treatment with deflazacort is as effective as methylprednisone and may lead to an improvement in the growth prognosis of children with renal transplantation.

Deflazacort (DFZ) pharmacokinetics was evaluated in fifteen pediatric patients on chronic hemodialysis or after renal transplantation, and in three normal children. After overnight fasting, oral DFZ 0.26+/-0.01 mg/kg (mean +/- SEM) was given. Serial blood samples were collected for 360 min and analyzed by HPLC for 21-hydroxy-DFZ (21-HO-DFZ). Serum concentration profiles and pharmacokinetic parameters were similar in patients on hemodialysis, renal transplant recipients and normal children. Elimination half-life was longer in the 9 cyclosporine-treated subjects (108.0+/-13.6 min) than in the other nine (71.2+/-8.3 min; p <0.02). Our finding suggests that, from a pharmacokinetic point of view, DFZ dose adjustment for renal function is not necessary in children with chronic renal failure or after renal transplantation.

Deflazacort is an oxazolone compound derived from prednisolone, with similar immunosuppressive action but fewer side effects. Kidney function, weight/height ratio, serum triglycerides, cholesterol, high-density lipoprotein (HDL) cholesterol, very-low-density lipoprotein cholesterol, low-density lipoprotein (LDL) cholesterol, apolipoprotein A, apolipoprotein B, and lipoprotein (a) were studied before and 6 months after 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 treated with cyclosporine, aged 3.1 to 20.3 years, 3 years after renal transplantation. 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. Total 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 to 114 +/- 12 mg/dL, P < .01), and TC/HDL cholesterol ratio by 28.3% (from 5.3 +/- 0.4 to 3.8 +/- 0.4, P < .01), whereas HDL cholesterol increased 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 deflazacort therapy. Our data suggest that substituting deflazacort for maintenance methylprednisone therapy leads to an improvement in the lipoprotein profile of children after renal transplantation.
