绝经后2型糖尿病患者骨质疏松影响因素及骨转换特点

目的 探讨绝经后2型糖尿病(T2DM)人群骨质疏松影响因素及骨转换特点及其防治策略.方法 150例绝经后T2DM住院患者测定骨密度(BMD)后分为骨量正常(NP)、骨量减低(DP)和骨质疏松(OP)组.登记年龄(Age),绝经年限(LOP),糖尿病病程(YSM),计算体重指数(BMI),测定空腹血糖(FPG)、餐后2 h血糖(PPG),空腹胰岛素(FIns)、餐后2 h胰岛素(2 h Ins),血Ⅰ型胶原C端肽(CTX-Ⅰ)、抗酒石酸酸性磷酸酶5b(TRACP5b)、骨特异性碱性磷酸酶(BALP)、雌激素(E2).结果 ①绝经后T2DM人群OP发病率54%;②绝经后T2DM并发OP患者与骨量减少和骨量正常组比较绝经年限、糖尿病病程及血糖水平明显增高,胰岛素和E2水平明显降低(P<0.05);③OP组患者与骨量减少和骨量正常组比较CTX-Ⅰ、TRACP5b、BALP等骨转换指标明显升高(P<0.05);④CTX-Ⅰ与腰椎2～4、股骨颈BMD呈明显负相关(P<0.05),与大转子、粗隆间BMD无明显相关性;TRACP5b、BALP与腰椎2～4、股骨颈、大转子、粗隆间BMD呈明显负相关(P<0.05).结论 LOP、血糖、YSM、FIns和E2水平可影响绝经后T2DM患者骨量;该人群骨重建特点为高转换型,骨吸收标记物TRACP5b可作为早期预测绝经后T2DM骨量减少及OP的敏感指标.

Factors of Bone mass and bone turnover characteristics in postmenopausal women with type 2 diabetes mellitus

Objective To explore factors of bone mass and bone turnover characteristics in postmenopausal type 2 diabetes mellitus(T2DM) population and management of post-menopausal osteoporosis with T2DM.Methods 150 cases of postmenopausal T2DM were divided into 3 groups according to bone mineral density(BMD): normal(NP),osteopenia(DP) and osteoporosis(OP) groups.Registration of age(Age),duration of menopause(LOP),duration of diabetes(YSM),calculation of body mass index(BMI),fasting plasma glucose(FPG),postprandial 2 ...
