Oxidized high-density lipoprotein as a risk factor for cardiovascular events in prevalent hemodialysis patients
چکیده انگلیسی

Background and objectivesHere, we assessed the impact of oxidized high-density lipoprotein (oxHDL), dysfunctional HDL, on mortality and cardiovascular disease (CVD) events in prevalent HD patients and compared oxHDL to interleukin-6 (IL-6), a strong predictor of CVD events in HD patients.Design, setting, participants, and measurementsThis prospective study examined a cohort of prevalent HD patients (n = 412). Blood samples were obtained at baseline to measure lipids, high-sensitive C-reactive protein (hsCRP), IL-6, oxidized low-density lipoprotein, N-terminal pro B-type natriuretic peptide, intercellular adhesion molecule 1 (ICAM-1), myeloperoxidase, adiponectin, and oxHDL. Carotid intima-media thickness (CIMT) was assessed at baseline and 3-year follow-up. Nutritional status was assessed by subjective global assessment (SGA), body mass index, and geriatric nutritional risk index (GNRI). After the baseline assessment, study patients were prospectively followed up (mean observational period, 40 months).ResultsAt baseline, patients with high oxHDL had a worse nutritional state and higher HDL-cholesterol (HDL-chol), ICAM-1, and adiponectin levels and a higher oxHDL/HDL-chol ratio than low oxHDL patients. A combination of high oxHDL and high IL-6 was significantly associated with increased CIMT at baseline and a larger increase in CIMT at 3-year follow-up. High oxHDL did not predict all-cause mortality; however, it was significantly associated with CVD-related mortality and composite CVD events, particularly with concomitant high IL-6. These associations were confirmed in multivariate Cox hazard models adjusted with confounding variables.ConclusionsHigh oxHDL, particularly with concomitant high IL-6, may be associated with an increased risk of CVD events and CVD-related mortality in prevalent HD patients.
