BACKGROUND/AIMS: Using a cohort of incident hemodialysis (HD) patients, this study investigated the impact of lipid profiles on clinical outcomes, especially in the early period of dialysis. METHODS: A prospective cohort of 867 incident HD patients was selected. In order to determine the impact of cholesterol level on primary outcome, Cox regression analyses were performed for LDL and non-HDL (NHDL) variables. RESULTS: Univariate analysis revealed an increase in primary outcome risk with an LDL cholesterol level of 100 mg/dl or higher compared to an LDL cholesterol level lower than 100 mg/dl. High LDL cholesterol remained a significant independent predictor of the composite outcome, even after adjusting for age, gender, diabetes mellitus, preexisting CV disease, albumin, and hs-CRP. CONCLUSION: Serum LDL cholesterol at the time of HD commencement was a significant independent risk factor for the composite outcome of all-cause mortality and CV events in incident HD patients during the early stages of dialysis.
