Patients with chronic kidney disease (CKD) develop premature cardiovascular disease. In the general population (without CKD), there are strong associations between cholesterol fractions and the risk of coronary disease and weaker associations with stroke. Randomised trials in the general population demonstrate that lowering blood cholesterol (chiefly with a statin) reduces the risk of vascular events. Patients with CKD differ significantly from the general population. They have markedly disturbed lipid metabolism manifesting as elevated triglyceride concentrations, reduced HDL cholesterol concentrations and a preponderance of small, dense LDL particles that are potentially more atherogenic; the observed association between lipids and vascular disease is bizarre, and is confounded by co-morbidity; the nature of the vascular disease appears less strongly associated with classical atherosclerosis. Randomised trials are required to determine the relevance of blood lipids to the development of vascular disease in CKD patients, but the results of such studies have been inconclusive to date. CKD patients are at risk of end-stage renal disease. Lipids may be involved in the progression of renal disease. Modifying them may delay the progression of CKD. The current data are based on effects on markers of progression (e.g. proteinuria). The ongoing SHARP (Study of Heart and Renal Protection) trial should provide reliable information about the effects of statins on both vascular and renal risk.
