RESUMO
Similar to adults, CKD may persist after pediatric RTx. Clinical and laboratory parameters were analyzed retrospectively in 23 RTx recipients (13 males, age 11.9 +/- 5.2 yr), initially treated with prednisone, calcineurin inhibitor (TAC = 18, cyclosporine neoral = 5), and MMF at four months post-RTx (T1) and at 3.4 +/- 2.8 yr post-RTx (T2). Mean (+/-s.d.) cystatin C GFR (mL/min/1.73 m(2)) was 72 +/- 19 at T1 and 70 +/- 22 at T2 (NS). At T2, CKD stage I was present in five patients (22%), stage II in eight patients (35%), and stage III in 10 patients (43%). At T2, calcineurin inhibitors were utilized in 19, MMF in 13, and SIR in 13 patients. The prevalence of hypertension was 69% at T1 and 87% at T2 (p = NS). Anemia was diagnosed in 61% at T1 and 69% at T2 with average therapeutic MMF (2.78 +/- 1.3 mg/mL) and SIR (7.62 +/- 2.3 mg/mL) trough levels. Hypercholesterolemia was detected in 44.0% at T1 and 47% at T2. Bone disease was diagnosed in 26.0% at T1 and 21.7% at T2. Mean height Z-scores were -1.0 +/- 1.2 (T1) and -1.0 +/- 1.59 (T2, NS), with 21% at T1 and 30% at T2 below two SDS. We observed suboptimal growth, hypertension, hypercholesterolemia, bone disease, and anemia in a significant proportion of transplanted children.
