Fish oil modifies lipids and reduces platelet aggregability in haemodialysis patients.

Abstract

Haemodialysis patients have an exceptionally high incidence of death from cardiovascular causes, related in part to abnormalities of lipids and platelets. Eskimos, however, have a low incidence of myocardial infarction and have a high dietary intake of fish, rich in omega-3 polyunsaturated fatty acids. We have, therefore, studied the effect of a fish oil MaxEPA, containing 3.6 g of the omega-3 polyunsaturated fatty acid eicosapentaenoic acid on lipids and platelet function in haemodialysis patients. Following 8 weeks of therapy there was a 35% fall in triglycerides, a 10% rise of high-density lipoprotein (HDL) cholesterol, a 36% rise of HDL2 cholesterol fraction and a 54% rise of the HDL2:HDL3 cholesterol ratio. The platelet aggregation to adenosine diphosphate and collagen was significantly reduced. The activated whole-blood clotting time was prolonged from 141 to 153 s, and 69% of patients showed a reduction of factor VIII related antigen which is usually elevated in haemodialysis patients and is thought to be a marker of endothelial damage. The blood pressure fell from 147/82 to 124/74. We have thus shown that a dietary supplement of eicosapentaenoic acid produces potentially beneficial effects on lipids, platelets, and blood pressure and may help to protect against atheroma and thus cardiovascular mortality in high-risk haemodialysis patients.
