Factors predictive of sustained growth in children after renal transplantation. The North American Pediatric Renal Transplant Cooperative Study.
To ascertain growth and rehabilitation of children after transplantation, the North American Pediatric Renal Transplant Cooperative Study collected growth data on renal transplant recipients. From January 1987 through December 1990, a total of 1553 children with one or more transplants were entered into the study by its 75 participating centers. Of these, the first 300 children with a functioning graft and 2 years of linear growth data form the cohort for this study. For the total cohort of 300 patients, the mean (+/- SEM) baseline height z score was -2.41 +/- 0.09, and the change in z score determined after 2 years was 0.18 +/- 0.06 (p < 0.01). Children in the age group from birth to 1 year had the maximal deficit and had the maximal improvement in z score, gaining about 1 SD (p < 0.01). For the 2- to 5-year-old group, the change in z score was about 0.5 SD (p < 0.001). No improvement in z score was noted for children 6 to 17 years of age. Each increase in serum creatinine concentration of 90 mumol/L (1 mg/dl) was associated with -0.17 decrease in the z score (p < 0.001). Gender, donor source, history of previous transplantation, and prior dialysis were not associated with a significant change in the z score; thus the increased rate of growth during the first 2 post-transplantation years occurred mainly in subjects less than 6 years of age.
