IMPACT OF SERUM LIPIDS ON LONG-TERM GRAFT AND PATIENT SURVIVAL AFTER RENAL TRANSPLANTATION1

Abstract

The results after primary cadaveric renal transplantation in 665 consecutive patients were reviewed with respect to posttransplant serum lipids. Data were available for 182 of 665 patients on serum total cholesterol and triglycerides at 1 year posttransplant. Hypercholesterolemia (cholesterol > 200 mg/dl) developed in 141 of 182 patients (77%) and hypertriglyceridemia developed in 73 of 166 patients (44%). At 1 year posttransplant, hypercholesterolemia and hypertriglyceridemia both correlated with age at transplant (P = 0.0001, P = 0.01). Hypercholesterolemia and hypertriglyceridemia were also correlated with obesity as determined by body mass index (kg/m2) (P = 0.006, P = 0.01). Hypertriglyceridemia at 1 year posttransplant correlated with pretransplant triglyceride level (P = 0.006), but hypercholesterolemia did not correlate with pretransplant cholesterol level (P = 0.53). Hyperlipidemia was not correlated with cyclosporine (CsA) or prednisone dose (mg/kg), CsA trough levels, number of rejection episodes, or serum creatinine at 1 year. Despite significant differences in serum cholesterol and triglycerides, actuarial graft and patient survival were similar between the normolipidemic and hyperlipidemic groups.
