Background Atherosclerotic vascular diseases such as cerebrovascular and cardiovascular diseases are major causes for fatality of hemodialysis (HD) patients. Since adipocytokines are key players for arteriosclerosis in the concept of metabolic syndrome (MetS), we aimed to determine whether circulating levels of major three adipocytokines, adiponectin, TNF-α, and leptin, could be associated with various parameters and clinical events in HD patients who are diagnosed as MetS using a new criteria designed for the Japanese population. Patients and Methods We enrolled 53 very stable patients under maintenance HD at Minami-Senju Hospital. Basically, clinical and laboratory data were taken just before HD therapy. HD sessions were performed regularly and all the participants took oral administration and injection as usual. A cross-sectional study was performed to evaluate clinical and laboratory data related to three major adipocytokines, adiponectin, TNF-α and leptin. Results We observed no significant differences of three adipocytokines when the participants were divided in accordance with existence of MetS or past cerebrocascular/cardiovascular diseases. Only the serum adiponectin levels were significantly different in two groups categorized by existence of diabetes mellitus. Serum triglycerides (TG) were significantly correlated with two circulating adipocytokines, adiponectin (r=-0.328, p<0.016) and leptin (r=0.397, p<0.003), when we analyzed all 53 patients together. Conclusion Plasma adiponectin and leptin are expected as contributors related to dyslipidemia, suggesting these may be targets of prevention of vascular diseases in maintenance HD patients.
