The incidence of cardiovascular disease (CVD) is very high in patients with chronic kidney (CKD) disease and in kidney transplant recipients. Indeed, available evidence for these patients suggests that the 10-year cumulative risk of coronary heart disease is at least 20%, or roughly equivalent to the risk seen in patients with previous CVD. Recently, the National Kidney Foundation's Kidney Disease Outcomes Quality Initiative (K/DOQI) published guidelines for the diagnosis and treatment of dyslipidemias in patients with CKD, including transplant patients. It was the conclusion of this Work Group that the National Cholesterol Education Program Guidelines are generally applicable to patients with CKD, but that there are significant differences in the approach and treatment of dyslipidemias in patients with CKD compared with the general population. In the present document we present the guidelines generated by this workgroup as they apply to kidney transplant recipients. Evidence from the general population indicates that treatment of dyslipidemias reduces CVD, and evidence in kidney transplant patients suggests that judicious treatment can be safe and effective in improving dyslipidemias. Dyslipidemias are very common in CKD and in transplant patients. However, until recently there have been no adequately powered, randomized, controlled trials examining the effects of dyslipidemia treatment on CVD in patients with CKD. Since completion of the K/DOQI guidelines on dyslipidemia in CKD, the results of the Assessment of Lescol in Renal Transplantation (ALERT) Study have been presented and published. Based on information from randomized trials conducted in the general population and the single study conducted in kidney transplant patients, these guidelines, which are a modified version of the K/DOQI dyslipidemia guidelines, were developed to aid clinicians in the management of dyslipidemias in kidney transplant patients. These guidelines are divided into four sections. The first section (Introduction) provides the rationale for the guidelines, and describes the target population, scope, intended users, and methods. The second section presents guidelines on the assessment of dyslipidemias (guidelines 1-3), while the third section offers guidelines for the treatment of dyslipidemias (guidelines 4-5). The key guideline statements are supported mainly by data from studies in the general population, but there is an urgent need for additional studies in CKD and in transplant patients. Therefore, the last section outlines recommendations for research.

The management of dyslipidemia in adults with diabetes is receiving more attention. However, there is a paucity of large, prospective, randomized outcome trials designed for diabetic patients. Diabetic dyslipidemia is characterized by an increase in triglyceride levels, low high-density lipoprotein (HDL) cholesterol concentrations, and small, dense low-density lipoprotein (LDL) particles. The treatment goals include an LDL cholesterol less than 100 mg/dL, triglyceride level less than 150 mg/dL, and an HDL greater than 40 mg/dL for men and more than 50 mg/dL for women. In the Diabetic Atherosclerosis Intervention Study, fenofibrate resulted in a 42% less increase in the percent stenosis, as assessed by quantitative coronary arteriography. The Heart Protection Study documented the unambiguous benefit of simvastatin in reducing all-cause mortality among 5963 diabetic patients. The Lescol Intervention Prevention Study observed a reduction in major adverse cardiac events in diabetics undergoing percutaneous intervention who received fluvastatin. The Veterans Affairs HDL Cholesterol Intervention Trial reported a reduction in major coronary events among 627 diabetic patients with low HDL cholesterol who sustained a myocardial infarction. The Fenofibrate Intervention and Event Lowering in Diabetics (FIELD) Trial (n = 9795), the Action to Control Cardiovascular Risk in Diabetes (ACCORD, n = 10,000), the Atorvastatin Study for Prevention of Coronary Heart Disease Endpoints in Non Insulin Dependent Diabetes Mellitus (ASPEN, n = 2421), and the Collaborative Atorvastatin Diabetes Study (CARDS, n = 2140) will provide the prospective outcome data that are needed for the management of patients. Combination drug therapy will be necessary to achieve treatment goals. Careful monitoring will be required to avoid myositis and hepatotoxicity.

In the general population, the relation between lipids and cardiovascular disease is clearcut, whereas it is highly controversial in chronic kidney disease (CKD) patients. This is primarily due to diverging results of retrospective observational trials. This study design often encounters confounding, especially in renal disease patients. Even if analyses are corrected for multiple influences, there might be unknown confounders changing the results. Prospective randomized trials assure that groups are comparable except for the intervention used. Confounding is eliminated by randomization. Nevertheless, the lipid discussion was restarted when two randomized, placebo-controlled, interventional trials on lipid-lowering therapy in renal patients have been published (Assessment of Lescol in Renal Transplantation and 4D Study [Atorvastatin in patients with type 2 diabetes on hemodialysis]). Surprisingly, both showed no significant reduction of the primary endpoint by statin therapy. In addition to other factors, this might be due to an altered pathogenesis of atherosclerosis in renal patients where multiple nontraditional cardiovascular risk factors are to be mentioned and different characteristics of cardiovascular disease with a high proportion of sudden cardiac death are present. This review will focus on dyslipidemia in renal failure and its treatment. The data published so far is summarized and grouped according to the different stages of CKD.

PMID:Lipid metabolism in chronic kidney disease: the role of statins in cardiovascular risk. 1719 38

Patients with chronic kidney disease including renal transplant recipients (RTRs) have a markedly higher prevalence of cardiovascular disease than the general population. Many trials have established the role of statins in the prevention of cardiovascular mortality, not only by decreasing the low density lipoprotein-cholesterol levels but also by their pleotropic effects. These data from the general population may not be applicable to RTRs as these patients have different cardiovascular risk profiles. Till date, only a few prospective, randomized trials have assessed the use of statins in RTRs with regards to cardiovascular outcomes. The Assessment of Lescol in Renal Transplant trial, the largest trial so far, suggested that dyslipidemia management with statins in RTRs is associated with a significant reduction in the incidence of cardiac death and nonfatal myocardial infarction (although differences in the combined primary end point were not statistically significant). The current guidelines from National Kidney Foundation for managing dyslipidemia in RTRs recommend managing all chronic kidney disease patients as a coronary heart disease equivalent. The task group for drafting these guidelines concluded that based on the currently available evidence, additional studies may be needed in RTRs to confirm and extend the results of Assessment of Lescol in Renal Transplant trial.
