• Bone mineral density
• Hemodialysis
• High-molecular-weight (HMW) adiponectin

Chronic kidney disease-mineral and bone disorder is a regular complication seen in hemodialysis patients and leads to substantial increases in the fracture rate, morbidity, and mortality. Discovered a few years ago, several clinical studies have shown a negative correlation between adiponectin and bone mineral density (BMD) independently of confounding factors. The relationship between adiponectin and bone metabolism in hemodialysis patients has not been fully described yet. We conducted this study to investigate the relationship between serum adiponectin concentration and the BMD in hemodialysis patients. %26lt;br%26gt;We enrolled 92 hemodialysis patients who were receiving maintenance hemodialysis therapy at Towa Hospital. A peripheral blood sample was obtained, and standard biological data and the serum high-molecular-weight (HMW) adiponectin level were measured. BMD was assessed using dual-energy X-ray absorptiometry scans. %26lt;br%26gt;In male hemodialysis patients, BMD was negatively related to age (r = -0.299, P = 0.012), duration of hemodialysis therapy (r = -0.31, P = 0.009), and log [HMW-adiponectin] (r = -0.31, P = 0.009) and positively related to body weight (r = 0.332, P = 0.004) and BMI (r = 0.297, P = 0.013). In female hemodialysis patients, BMD was negatively related to age (r = -0.499, P = 0.018) and log [HMW-adiponectin] (r = -0.46, P = 0.030) and positively related to triglyceride (r = 0.491, P = 0.020). %26lt;br%26gt;HMW adiponectin may affect bone metabolism in both male and female hemodialysis patients.
