摘要
目的探讨绝经后2型糖尿病患者的骨密度变化与N-端骨钙素(N-MID)、总1型胶原氨基端延长肽(T-P1NP)、B-胶原特殊序列(β-CTX)、25羟维生素D水平〈25(OH)Ds]及胰岛素样生长因子-1(IGF-1)的相关性。方法选取绝经后女性2型糖尿病患者116例,根据骨密度水平进行分3组,骨量正常组29例、骨量减少组49例和骨质疏松组38例。测量患者身高、体质量,计算体质指数。测定患者空腹血糖(FBG)、餐后2h血糖(PPG)、糖化血红蛋白(HbAlc)及24h尿蛋白定量(U-PRO),测定3组患者的N-MID、T-P1NP、BCTX、25(OH)D。及IGF-1的水平,比较3组患者-般临床资料和骨代谢指标并进行统计学分析。结果3组患者的FBG、PPG、HbAlc、病程及25(0H)D。差异无统计学意义(P〉0.05);与骨量正常组比较,骨量减少组和骨质疏松组的体质指数、IGF-1的水平降低(P〈0.05),T-P1NP、N-MID水平降低(19.85±2.83)txg/L与(12.23±2.75)μg/L、(9.16±2.86)μg/L.(均P〈0.05),(7.12±2.05)μg/L与(5.06±2.38)μg/L、(4.92±2.12)μg/L(均P〈0.05);24hUPro升高(P〈0.05),8-CTX升高(1.32±0.38)μg/L与(1.97±0.58)μg/L、(2.14±0.73)μg/I.(均P〈0.05);Logistic回归分析结果显示,骨密度与T-P1NP、IGF-1、25(OH)D3、N-MID、体质指数呈正相关(r值分别为0.35l、0.217、0.213、0.273、0.203,P值分别为0.001、0.01l、0.012、0.001、0.012),与8-CTX、24hUPro呈负相关(r值分别为-0.236±0.216,P值分别为0.013、0.015)。结论绝经后2型糖尿病患者易合并骨量减少或骨质疏松,其骨密度变化与骨代谢标志物及IGF-1水平密切相关,对绝经后2型糖尿病患者应进行常规检测,及早防治,避免骨折的发生。
Objective To explore the correlation of bone mineral density (BMD) with levels of N-terminal osteocalcin (N-MID), total collagen type 1 amino-terminal extension peptide, β-collagen special sequence (β-CTX), 25-hydroxy vitamin D (25 (OH) D3] and insulin-like growth factor-1 (IGF-1) in postmenopausal women with type 2 diabetes. Methods 116 elderly postmenopausal women with type 2 diabetes were divided into 3 groups according to BMD level: normal group (n= 29), osteopenic group (n= 49) and osteoporosis group (n= 38). Body height, weight, body mass index (BMI) were measured. Fasting blood glucose (FBG), 2-hour postprandial glucose (PPG), glycated hemoglobin (HbAlc), 24-hour urinary protein (UPro) and levels of N MID, T-P1NP,- CTX, 25(OH)D3 and IGF-1 were determined. General informations and bone metabolic markers were statistically analyzed and compared between the 3 groups. Results There were no significant differences in levels of FBG, PPG, HbAlc, 25(OH)Da and duration between the 3 groups (all P〈0.05). For the comparison of normal group with osteopenic and osteoporosis groups, BMI and IGF-1 levels were decreased (both P〈0.05); T-PINP and N-MID levels were decreased ((19.85±2.83) μg/L vs. (12.23±2.75) μg/L, (9.16±2.86) μg/L; (7.12±2.05) μg/L vs. (5. 06±2.38) μg/L, (4.92±2.12) μg/L, all P%0. 053 ; 24 h urine protein was increased (P〈0.05) ; 13-CTX level was increased ((1. 32 t0. 38)μs. (1.97±0.58) μg/L, (2.14±0.73) 〉g/L, P〈0.053. Logisticregression analysis showed that BMD was positively correlated with total collagen type 1 amino terminal extension peptide, IGF-1, 25(OH)D3, N-MID and BMI (r=0. 351, 0. 217, 0. 213, 0.273, 0. 203, respectively, P〈0.01 or 0.05), and BMD was negatively correlated with CTX and urinary protein levels (r =0. 236 and r=- 0. 216, P〈 0.05 ). Conclusions Osteopenia or osteoporosis occurs more often in postmenopausal women with type 2 diabetes. The change of BMD is closely related with bone metabolism markers and IGF-1 level. Routine tests and early prevention can avoid fracture in postmenopausal women with type 2 diabetes.
