    Abstract:
    Hyperlipoproteinemia is frequently observed in patients after renal transplantation and contributes to cardiovascular morbidity and mortality. In addition, it was recently shown that hypercholesterolemia accelerates the progression of renal disease. In a renal transplant recipient (RTR) with severe coronary heart disease, familial hypercholesterolemia and decreased renal function, immunospecific LDL-apheresis was instituted since dietary restrictions failed to sufficiently improve hyperlipoproteinemia and medication had to be avoided due to drug interactions. Over a period of 36 months 145 LDL-apheresis treatments were performed at weekly intervals. The desorption of 5600 ml plasma volume allowed a mean reduction of total cholesterol by 56.6% (from 256 mg/dl to 110 mg/dl), of LDL-cholesterol by 63.0% (from 163 mg/dl to 58 mg/dl), of Lp(a) by 68.3% (from 34 mg/dl to 11 mg/dl) and of triglycerides by 49.6% (from 332 mg/dl to 163 mg/dl). Although temporarily decreasing during each apheresis session by 9.0%, HDL-cholesterol values increased during the first 9 months of treatment and remained within the normal range (> 45 mg/dl) thereafter. Cyclosporine A blood trough values were decreased by 32% during LDL-apheresis. Symptoms of angina pectoris rapidly improved and disappeared after 8 months of apheresis treatment. Initial coronary angiography exhibited serious three-vessel-disease, without the possibility of bypass grafting. Coronary angiography repeated after two years of therapy showed a regression of the disease. Serum creatinine levels declined during treatment (from 2.7 mg/dl to 1.8 mg/dl) and proteinuria did not increase further. This is the first report to show that long-term LDL-immunoadsorption is a safe and highly effective treatment of severe hyperlipidemia and coronary heart disease in a RTR, resulting in regression of vascular pathology. Moreover, amelioration of hyperlipidemia may have improved transplant function. Multicenter studies are necessary to confirm our results.
