Abstract/OtherAbstract:
The aim of this study was to investigate the bone status of hemodialysis patients and identify factors that have influence on bone quality. Four hundred eighty-nine subjects (213 males and 276 females) on maintenance hemodialysis and 696 healthy subjects (309 men, 387 women) were enrolled in this study. Speed of sound (SOS), broadband ultrasound attenuation (BUA) and quantitative ultrasound index (QUI) were assessed by quantitative ultrasound (QUS) at the right calcaneus in both groups. Serum levels of intact parathyroid (iPTH), total alkaline phosphatase (ALP), calcium and phosphate were measured to determine their influence on bone status in hemodialysis patients. All QUS parameters were significantly lower in hemodialysis patients than in controls (p < 0.0001). Stepwise multiple linear regression analysis in male patients indicated that age, weight, calcium-phosphate product and ALP were significant predictors of QUS parameters (adjusted R(2) = 0.15 in SOS; adjusted R(2) = 0.17 in BUA and QUI). In female patients, same findings including number of parity were observed in SOS only (adjusted R(2) = 0.25 in SOS). In postmenopausal patients, the duration of menopause was significant negatively correlated with all QUS parameters (p < 0.01). In conclusion, patients on maintenance hemodialysis had additional risk of bone loss. Advanced age, low body weight, high calcium-phosphate product and high ALP level were important risk factors for deterioration of bone quality.
