Although high serum total cholesterol and LDL cholesterol levels are predictive of cardiovascular diseases in the general population, this association is more complex in the dialysis patients. Two recent randomized trials failed to show significant beneficial effects of statins on the primary cardiovascular outcomes in these patients. The reasons for this lack of benefits are unclear. The postulates include the possibilities that LDL cholesterol is not important in atherogenesis and that atherosclerosis is not a major contributor to cardiovascular diseases in the dialysis population. It is important to note that high serum LDL cholesterol level is not a prominent feature of uremic dyslipidemia. Instead, the hallmark dyslipidemias in the dialysis population are hypertriglyceridemia as a result of the accumulation of lipoprotein remnant particles, low serum HDL cholesterol levels, high serum levels of lipoprotein(a) [Lp(a)], and the modification of LDL cholesterol by oxidation and carbamylation. In vitro and epidemiologic studies have further suggested that these abnormal lipoproteins or aberrant serum lipoprotein levels are atherogenic. More research efforts should be directed toward these dyslipidemic states and the multitude of other putative cardiovascular risk factors in dialysis patients.
