Abstract

Objective: To determine the prevalence and identify variables associated with renal dysfunction in long-term survivors of pediatric liver transplantation. Study design: Data from 117 patients who survived ≥3 years after liver transplantation were analyzed. Demographic and clinical information was obtained from chart review and from a clinical care database. The dependent variable was renal function as determined by measured glomerular filtration rate (mGFR). Univariate and multivariate analyses were performed to identify independent variables associated with renal dysfunction (mGFR <70 mL/min per 1.73 m2). Results: The average time since liver transplant was 7.6 ± 3.4 years (range, 3 to 14.6 years). When the last available mGFR for all patients was analyzed, renal dysfunction was present in 32%. In the univariate analysis, mGFR at 1 year after transplant, cyclosporine immunosuppression, and time since transplant were significant; the second two were strongly collinear. Using multiple logistic regression modeling excluding time since transplant, cyclosporine and mGFR at 1 year after transplant were strongly associated with renal dysfunction. Conclusions: Renal dysfunction is a common complication in children who survive liver transplantation. Our observations are of critical importance because children may live long enough to move from a stage of renal insufficiency characterized by asymptomatic decreased GFR to symptomatic end-stage renal disease.
