Adiponectin is related to carotid artery plaque and a predictor of cardiovascular outcome in a cohort of non-diabetic peritoneal dialysis patients

• <i>Aims:</i> Adiponectin is an adipocytokine with antiatherogenic and anti-inflammatory properties. We investigated associations between circulating adiponectin, inflammation and cardiovascular disease in peritoneal dialysis patients. <i>Methods:</i> A prospective study was performed in 59 non-diabetic patients. The concentrations of serum adiponectin, biochemical data and ultrasound of carotid artery were measured at enrollment. The patients were followed up to 39 months mainly for cardiovascular events. <i>Results:</i> The serum adiponectin concentration was elevated and inversely related to C-reactive protein and interleukin-6 in the patients. The adiponectin level of patients with carotid plaques was significantly lower than in those without plaques (p < 0.01). Kaplan-Meier analysis showed that the cumulative survival without new cardiovascular events was better in patients with higher adiponectin levels than in those with lower adiponectin levels. <i>Conclusion:</i> Serum adiponectin levels are inversely related with markers of systemic inflammation and signs of atherosclerosis which may explain why hyperadiponectinemia in this study was associated with better cardiovascular outcome.
