Improved long‐term allograft function in pediatric renal transplantation with mycophenolate mofetil

Abstract:  MMF has been shown to decrease the incidence of acute rejection in children and adults at 1 and 3 yr. Other beneficial effects of MMF have been more difficult to demonstrate. Our open‐labeled study presents a 5‐yr data for patients and graft survival, allograft function, and growth in MMF‐treated patients. The trial included 29 patients who were treated with MMF in combination with cyclosporine and methylprednisone. Patients were compared with a preceding group of 29 patients treated with AZA instead of MMF. Patient and graft survival rate 5 yr after transplantation were 97 and 90% in the MMF group vs. 93 and 83% in the AZA group (p: NS). Acute rejection was 20.6% in the MMF group vs. 58.6% in the AZA group (p < 0.01). Chronic rejection was 10.3% in the MMF group and 25% in the AZA group (p: NS). The changes in the creatinine clearance from baseline to 5 yr (Δ) were different between groups (−6.0 ± 5.1 mL/min/1.73 m2 in the MMF group vs. −22.2 ± 7.6 mL/min/1.73 m2 in the AZA group, p < 0.05). Also, the slope of 1/Scr showed a significant lower incidence of worsening renal function after the second year of renal transplantation (p < 0.0001) in the MMF group compared with the AZA group. Δ Height SDS in prepubertal patients was 0.3 ± 0.4 SDS in the MMF group vs. −0.8 ± 0.2 SDS in the AZA group (p < 0.05).
