title: Lipid-lowering therapy in chronic kidney disease: is there a role for ezetimibe?
abstract: The use of lipid-lowering therapy (LLT) in chronic kidney disease (CKD) results in a reduction in atherosclerotic cardiovascular events but not mortality. The risk reduction for patients on dialysis appears to be less than in pre-dialysis CKD. These findings may be due to the higher rate of non-atherosclerotic cardiovascular disease found in end-stage disease. Because of this, the role of LLT is less clear in CKD than in the general population. This review outlines the results of recent trials of LLT, particularly Ezetimibe, and implications for patients with CKD. The evidence in favour of lipid lowering in CKD comes largely from the SHARP study. This study used combined simvastatin and Ezetimibe to reduce cholesterol. Though the benefits of statins are well proven, there is no evidence that Ezetimibe independently reduces cardiovascular events in any population. Data which support the use of Ezetimibe show only that it effectively reduces cholesterol. Surrogate end-point data are contentious. Some studies suggest benefit whilst others suggest off-target effects that question the validity of Ezetimibe in the absence of quality cardiovascular outcome data.
