Abstract
Previous studies of bone turnover markers in diabetes are limited, and the results are conflicting. Our aim was to evaluate differences in bone turnover markers and i-PTH between T2DM and non-diabetes subjects. Cross-sectional study including 133 subjects (78 T2DM, 55 without diabetes). BMD were measured by dual X-ray absorptiometry. Bone turnover markers were determined in serum. Serum levels of bone resorption markers (CTX and TRAP5b) were lower in T2DM compared with non-diabetes subjects. There were no differences in bone formation markers. i-PTH serum levels were lower in T2DM: 38.35 ± 18.20 pg/ml versus 50.22 ± 18.99 pg/ml, P < 0.05. TRAP5b and CTX were positively correlated with i-PTH (CTX: r = 0.443, P < 0.001; TRAP5b: r = 0.180, P = 0.047). There was an inverse relationship between TRAP5b levels and diabetes duration (r = −0.269, P = 0.021). T2DM patients have lower levels of bone resorption markers, and i-PTH compared with subjects without diabetes. Lower levels of PTH may induce a low turnover state as reflected by lower levels of bone resorption markers, and this situation may influence the higher risk of fracture of T2DM.
