    Abstract:
    Persistent hyperlipidemia and hypercholesterolemia post-transplantation are risk factors for accelerated atherosclerosis. To evaluate the natural history of lipid abnormalities in children post-transplantation, this study utilized a cohort of 29 patients who were all treated with the same three- drug maintenance immunosuppression (cyclosporine, azathioprine, and prednisone) and whose dosing regimen was rigidly controlled. Fasting blood samples were taken monthly to determine lipid profiles measuring total cholesterol (CHOL), triglycerides (TG), high-density lipoprotein cholesterol (HDL), very low density lipoprotein cholesterol (VLDL), and levels of lipoprotein (a) (LP(a)). A mean value was determined for each of five time periods: 0-3 months, 3-6 months, 6-9 months, 9-12 months and 12-15 months post-transplant. A single specimen of fasting lipid profile was drawn from 21 non-immunosuppressed children attending an ambulatory pediatric clinic and used as control. Despite significant reductions in the cyclosporine and prednisone doses post-transplantation, significant reduction in any of the lipid parameters was only noted after the first year. Reductions in the HDL fraction and in the TG level were noted during the 12-15 month period, however the values obtained in the patient population were significantly elevated for CHOL, TG, LDL and VLDL compared to controls. This study, using a fixed protocol, suggests that the lipid profile should be measured at one year post-transplant in all transplant patients, and if subsequent follow-up continues to exhibit abnormally elevated levels of CHOL and LDL, interventional therapy should be considered.
