Abstract |
Objective s: Abnormal bone turnover and mineralization is the characteristic of the end-stage renal disease (ESRD)
patients receiving dialysis treatment. Reduced bone mineral density (BMD) has been reported in ESRD patients in
many recent studies. Recent study has demonstrated hypoxia increases the loss of bone mass whereas the use of
erythropoietin (EPO) increases bone marrow mesenchymal stem cell in vitro, which is the commonly found in ESRD
patients. The objective of the present study is to analyze the relationship between erythropoiesis and calcium,
phosphorus, parathyroid hormone (PTH) status in ESRD patients.
Methods This study was a cross-sectional analysis of 183 ESRD patients (78 males, 105 females) on dialysis with
mean age of 52 ± 13 years and mean dialysis duration of 3.4 ± 3.0 years. Duration and dose of EPO administration,
hemoglobin, serum ferritin, and iron were checked in all subjects. BMD was evaluated by DXA.
Results Age was negatively, and body weight and c-calcium positively associated with spine and femur neck and
total hip BMD. Hemoglobin was positively correlated with femur neck and total hip BMD. Total dose of EPO, iPTH,
and alkaline phosphatase had no significant association with BMD. However, according to tertile of serum PTH
concentration, BMD were worst in third tertile group. In multivariate linear regression analysis, age, weight, and serum
PTH affect BMD.
Conclusions BMD was independently related with age and weight. Hemoglobin correlated positively with femur
neck and total hip BMD. However, treatment with EPO had no association with BMD. Increased PTH was related
with reduced BMD. |
