Abstract
Children with chronic renal insufficiency (CRI) secondary to congenital structural abnormalities frequently have significant growth retardation by 2 years of age. In a multicenter placebo-controlled study of the use of recombinant human growth hormone (rhGH), 30 of 125 (24%) participants weren=19) received rhGH 0.05 mg/kg per day subcutaneously and one-third (n=11) received placebo injections. At entry into the study, the mean (± SD) calculated creatinine clearance was 29.2±14.3 (range 12.0−63.7) ml/min per 1.73 m2 in the rhGH-treated group and 23.3±15.1 (range 8.0−59.4) ml/min per 1.73 m2 in the placebo-treated group. The 1st year growth rate was 14.1±2.6 cm/year for the rhGH-treated group and 9.3±1.5 cm/year in the placebo-treated group (PP=0.025). The Δ height standard deviation score was +2.0±0.7 for the rhGH-treated group compared with −0.2±1.1 in the placebo-treated group (P<0.00005) during the 2 years of the study. Minor adverse events occurred with similar frequency in both groups. These data suggest that rhGH is efficacious and safe in children with CRI under age 2.5 years. rhGH therapy may correct significant loss of growth at this age when used in conjunction with optimal medical management.
