Can pediatric steroid‐free renal transplantation improve growth and metabolic complications?

Abstract

We analyzed the effects of a steroid avoidance protocol in pediatric renal transplant recipients on calculated CrCl (Schwartz), CMV infection, cholesterol, height Z scores, weight Z scores, and BMI Z scores in a case control trial with contemporaneous controls. From 1999 to 2004, 19 pediatric patients (age 1-20 yr) received transplants without steroids using immunosuppression with tacrolimus, mycophenolate mofetil, and daclizumab. Control patients (n = 30) were matched for length of follow-up (minimum one yr), donor type age, type of immunosuppression, sex, date of transplant, and original disease, and CMV status. Graft survival at one year was 100% in both groups. Mean CrCl of steroid-free vs. control patients were not different at 1 year post-transplant. CMV disease was more prevalent in steroid-treated control group (seven of 30 patients) vs. the steroid free control group (zero of 19). Height delta Z scores at one year were NOT different between groups. Weight and BMI delta Z scores were significantly higher in the control group. Cholesterol levels at one year post-transplant were different in the two groups but NOT ABNORMALLY elevated in either group. At one yr post-transplant, steroid-free immunosuppression with tacrolimus, mycophenolate mofetil and daclizumab provides outcomes that are equivalent or superior to those in contemporaneous control patients receiving steroids.
