title: Use of atorvastatin in hyperlipidemic hypertensive renal transplant recipients.
abstract: The aim of the present short-term study was to evaluate the use of a new HMG-CoA reductase inhibitor, atorvastatin, in the treatment of hyperlipidemia and the effect on blood pressure in a group of hypertensive stable renal transplant recipients with hypercholesterolemia who received kidney grafts before 18 years of age. Eight patients (aged 10.8-30.1 years) with inadequately controlled total cholesterol (TC) levels by a lipid-lowering diet (8 weeks) were treated daily for 12 weeks with atorvastatin at an initial dose of 2.5 mg. The dose was increased monthly by 2.5 mg in order to lower TC levels to less than 200 mg/dl. Serum lipoprotein profile, cyclosporin A (CsA), serum creatinine (SCr), and liver and muscle enzyme levels were measured before starting the lipid-lowering diet, at the start of treatment (baseline), and during treatment. Ambulatory blood pressure monitoring (ABPM) (24-h) was carried out in each patient at both baseline and the end of the follow-up. During the lipid-lowering diet, no significant changes in lipoprotein parameters were observed. Atorvastatin was tolerated well and no clinical side effects were noted during the follow-up. The final dose of atorvastatin ranged from 2.5 to 7.5 mg/day. At the end of the study, TC was reduced by 32.2% ( P<0.05), low-density lipoprotein cholesterol (LDL-C) by 41.8% ( P<0.05), and apo B by 29.5% ( P<0.05). No significant changes in HDL-C, VLDL-C, apolipoprotein AI, and lipoprotein(a) were observed. SCr and CsA levels were unaffected. Overall, no significant changes in mean 24-h, daytime, and nighttime ABPM values between the first and the second recordings were observed. However, both daytime and nighttime systolic and diastolic ABPM values dropped in four patients. In conclusion, low-dose atorvastatin appears to be safe, well tolerated, and effective in the treatment of post-transplant hyperlipidemia. In addition, the capacity of atorvastatin to reduce blood pressure, whether or not related to its lipid-lowering action, deserves further investigation.
