Conversion From Cyclosporine Microemulsion to Tacrolimus in Stable Kidney Transplant Patients With Hypercholesterolemia Is Related to an Improvement in Cardiovascular Risk Profile: A Prospective Study

The aim of this prospective multicenter study was to evaluate the effect of conversion from cyclosporine (CsA) to tacrolimus (Tac) on cardiovascular risk factors in stable kidney transplant patients with hyperlipidemia. Twenty-six patients were switched from CsA to Tac at 81.7 ± 44.4 months after transplantation. Tac was started at 0.15 mg/kg/d. Patient outcomes were evaluated up to 6 months after conversion. Significant reductions were seen in systolic blood pressure (143 ± 13 baseline to 136 ± 9 mm Hg at 6 months, P = .026) as well as the need for antihypertensive medication, with no changes in diastolic blood pressure. There was a significant reduction in total cholesterol (247 ± 41 to 221 ± 35 mg/dL, P = .003), low-density lipoprotein cholesterol (150 ± 24 to 127 ± 27 mg/dL, P = .001), total cholesterol/high-density lipoprotein (HDL) cholesterol ratio (4.9 ± 1.9 to 3.9 ± 1, P = .02), and triglyceride levels (228 ± 175 to 148 ± 71 mg/dL, P = .026). No significant modifications in HDL cholesterol, Apo A1 and Apo-B levels, or in the need for lipid-lowering medication were observed. Glucose levels did not change, but an increase in HbAC1 took place (5.8 ± 1.1 to 6.2 ± 1, P = .002). In men Framingham risk score significantly decreased from 11.5 ± 11.3 to 8.4 ± 7.2. (P = .0023). In conclusion, elective conversion from CsA to Tac in stable kidney transplant patients with hyperlipidemia was related to an improved blood pressure and lipid profile, both suggesting a decrease in the estimated 10-year coronary heart disease risk in men.
