title: Correlation of serum uric acid with bone mineral density and fragility fracture in patients with primary osteoporosis: a single-center retrospective study of 253 cases.
abstract: OBJECTIVE
  This study aimed to investigate the correlation of serum uric acid with bone mineral density (BMD) and fragility fracture in primary osteoporosis (PO) patients.
  
  
  METHODS
  A retrospective analysis of biochemical parameters including bone turnover markers and bone density was done in patients (n=253) received initial treatment for PO from January 2011 to May 2012 at the Shanghai First People's Hospital.
  
  
  RESULTS
  Pearson correlation analysis and multiple regression analysis showed that serum uric acid positively correlated with the lumbar spine BMD (P<0.05); serum uric acid negatively correlated with urine calcium/creatinine ratio, but positively correlated with blood 25-hydroxyvitamin D (25 [OH] D) (P<0.05); the serum uric acid in postmenopausal women with the history of fragility fracture was significantly lower than that in women without the this disease history.
  
  
  CONCLUSIONS
  Serum uric acid may be a protective factor of bone metabolism in primary osteoporosis patients.
