Abstract.
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.
