Negative correlation of serum adiponectin level with peripheral artery occlusive disease in hemodialysis patients.

Objective: Adiponectin is a fat-derived hormone that secretes exclusively by adipocytes and has antiatherosclerotic effects. Peripheral arterial occlusive disease (PAOD) is associated with an increased risk of death in hemodialysis (HD) patients. The aim of this study was to evaluate the relationship between serum adiponectin levels and PAOD by ankle-brachial index (ABI) in HD patients.

Materials and Methods: Blood samples were obtained from 100 HD patients. Serum adiponectin levels were measured using a commercial enzyme-linked immunosorbent assay kit. ABI values were measured using the automated oscillometric method (VaSera VS-1000). ABI values that <0.9 were included in the low ABI group.

Results: Among the 100 HD patients, 18 of them (18.0%) were in the low ABI group. Compared with patients in the normal ABI group, the patients in the low ABI group had a higher prevalence of diabetes ( P = 0.043), older age ( P = 0.027), and lower serum adiponectin level ( P = 0.003). In addition, the multivariable logistic regression analysis showed that adiponectin (Odds ratio [OR]: 0.927, 95% confidence interval [CI]: 0.867-0.990, P = 0.025) and age (OR: 1.054, 95% CI: 1.002-1.109, P = 0.043) were the independently associated with PAOD in HD patients.

Conclusion: In this study, serum adiponectin level was found to be associated with PAOD in HD patients.
