Objective A number of vasculo-protective roles have been reported for adiponectin. In contrast, higher, rather than lower, plasma adiponectin levels are associated with an increased risk of cardiovascular disease and mortality in patients undergoing hemodialysis (HD). The mechanisms by which high adiponectin levels are associated with adverse outcome are unclear. Methods This study measured the level of total and high molecular weight (HMW) adiponectins in 70 patients with HD patients (age: 65.2±8.6 years, man/woman: 30/40), and examined the association between adiponectins, metabolic and echocardiographic parameters. Results Women had a significantly higher total, HMW levels and HMW to total ratio than men. The levels of total and HMW adiponectin were positively correlated with those of HDL-cholesterol and B-type natriuretic peptide (BNP) levels, and negatively associated with body mass index (BMI), triglyceride, high sensitive-C reactive protein (CRP) and hemoglobin levels. A multiple linear regression analysis showed that HMW adiponectin had an independent association with BMI (β=-0.270, p=0.003), HDL-cholesterol (β=0.356, p<0.001), hemoglobin (β=-0.180, p=0.034) and BNP (β=0.200, p=0.014) as total did adiponectin. Conclusion Anemia and BNP levels had independent influence on the total and HMW adiponectin levels in chronic HD patients.
