随着我国步入老龄化社会,骨质疏松症的患病率明显升高。骨质疏松症最严重的危害来自骨质疏松性骨折,绝经后女性尤其多见。由于脊柱独特的解剖学和生物力学特点,骨质疏松患者更易发生椎体骨折。骨密度测量是诊断骨质疏松的金标准。本文通过回顾近年来相关文献,探讨腰椎体骨密度检测对绝经后女性骨质疏松性椎体骨折的意义,发现:绝经后骨质疏松性椎体骨折患者的BMD水平比绝经后骨质疏松症但无脊椎骨折者明显减少;绝经后骨质疏松症患者的BMD水平越低,其发生椎体骨折的风险越高;有椎体骨折史的绝经后骨质疏松症患者的BMD水平与发生再次椎体骨折的风险呈负相关。药物干预通常可明显提高绝经后骨质疏松症患者的BMD水平,同时还可减少椎体骨折的发生。尚存在一些不足:腰椎骨密度可能出现假性增高;需进一步探讨预测骨质疏松性椎体骨折的骨密度阈值;药物干预的研究中BMD水平与椎体骨折发生的相关性并没有得到深入研究;缺少大规模的绝经后骨质疏松性椎体骨折的流行病学,现有研究也大都存在病例收集方法不规范、样本量小、年龄分布存在差异等不足。对绝经后骨质疏松性椎体骨折的深入研究需要多学科共同协作。 相似文献

绝经后骨质疏松症患者骨密度及骨代谢参数的调查研究 总被引:11,自引:1,他引:10
目的 了解E2和IL-6在骨质疏松症发病中的作用。方法 选择绝经后妇女120例,绝经后有骨质疏松60例(OP组),绝经后无骨质疏松60例(NOP组),另外选择绝经前妇女60例为对照组。对180名妇女雌二醇(E2)、骨密度(BMD)、白细胞介素-6(IL-6)、血清总碱性磷酸酶(ALP)、骨钙素(BGP)、尿羟脯氨酸肌酐比值(尿Hoc/Cr)、尿钙肌酐比值(尿Ca/Cr)等指标进行了测定。结果 绝经后妇女骨形成指标BGP及ALT明显高于对照组妇女,其中ALP在OP组和NOP组间有差异,而BGP在OP组和NOP组间无差异;绝经后妇女骨吸收指标尿HOP/Cr及尿Ca/Cr明显高于对照组妇女,OP组尿HOP/Cr及尿Ca/Cr又明显高于NOP组;绝经后妇女的血清E2的含量明显低于对照组(绝经前妇女),OP组又明显低于NOP组;绝经后妇女血清IL-6的含量明显高于对照组妇女,而OP组又明显高于NOP组。结论 本研究证明E2、IL-6与骨质疏松关系密切,雌激素水平的下降,IL-6分泌增多,是导致骨吸收加速的重要原因之一。 相似文献

The purpose of this prospective study was to determine whether moderate walking exercise in postmenopausal women with osteopenia/osteoporosis would affect bone metabolism. Fifty postmenopausal women, aged 49–75 years, with osteopenia/osteoporosis were recruited: 32 women entered the exercise program (the exercise group) and 18 served as controls (the control group). The exercise consisted of daily outdoor walking, the intensity of which was 50% of maximum oxygen consumption, with a duration of at least 1h with more than 8000 steps, at a frequency of 4 days a week, over a 12-month period. Lumbar (L2–L4) bone mineral density (BMD) was measured at the baseline and every 6 months with dual-energy X-ray absorptiometry (DXA) in both groups. Serum bone-specific alkaline phosphatase (BAP) and urinary cross-linked N-terminal telopeptides of type I collagen (NTX) levels were measured at baseline and at months 1, 3, 6, 9, and 12 by EIA and ELISA, respectively, in the exercise group, and urinary NTX level was measured at the baseline and every 6 months in the control group. There were no significant differences in baseline characteristics including age, height, body weight, bone mass index, years since menopause, lumbar BMD, and urinary NTX level between the two groups. Although no significant changes were observed in lumbar BMD and the urinary NTX level in the control group, lumbar BMD in the exercise group was increased as compared with the control group, but was sustained from the baseline. In the exercise group, the urinary NTX level rapidly responded to walking exercise from month 3, and this reduction was sustained until month 12, followed by reduction in the serum BAP level. A moderately negative correlation was found between the percent change in the urinary NTX level at month 3 and that in lumbar BMD at month 12 in the exercise group. This study clearly demonstrates that the mechanism for the positive response of lumbar BMD to moderate walking exercise in postmenopausal women with osteopenia/osteoporosis appears to be the suppression of bone turnover, and that an early change in the urinary NTX level may be useful to predict the long-term response of increasing lumbar BMD to exercise, although its efficacy for lumbar BMD may be quite modest. 相似文献

目的 探索血清白细胞介素-33(IL-33)与绝经后骨质疏松女性骨密度和骨代谢指标相关性。方法 采用酶联免疫吸附法测定50例绝经后骨质疏松患者和50例正常绝经后妇女血清IL-33水平。采用双能X线骨密度仪(DXA)测量患者和对照组的骨密度(BMD)。检测维生素D、钙、碱性磷酸酶(ALP)、甲状旁腺激素(PTH)水平,以及1型胶原C末端肽(CTX)和1型前胶原N端前肽(P1NP)等骨转换指标。结果 在绝经后骨质疏松症女性中,IL-33水平显著低于健康对照组[(3.53±2.45) pg/mL vs (13.72±5.39) pg/mL,P=0.007];Spearman相关分析表明血清IL-33水平与年龄、BMI、PTH、CTX和P1NP水平呈负相关,与腰椎BMD和股骨颈BMD呈正相关。多元回归分析表明,年龄、BMI、腰椎BMD、PTH、股骨颈BMD和血清CTX和P1NP水平是骨质疏松症患者血清IL-33水平降低的独立预测因子。结论 血清IL-33降低是绝经后骨质疏松患者股骨颈和腰椎骨密度降低和骨转换增速的危险因素。 相似文献

Alendronate has recently been approved for the prevention and treatment of postmenopausal osteoporosis, and its efficacy has been demonstrated in many Western countries. Our present study was performed to evaluate the effect of alendronate on bone mineral density (BMD) and its tolerability in Thais. Eighty postmenopausal women with osteoporosis participated in this study. After giving informed consent, the subjects were randomly allocated either 10mg alendronate or placebo in a double-blind fashion. All patients received a supplement of 500mg elemental calcium daily. BMD at the lumbar spine, femoral neck, and distal forearm was measured at baseline and 6 and 12 months after treatment. Biochemical markers of bone resorption were determined at baseline and 6 months after treatment. Baseline characteristics were similar in both alendronate- and placebo-treated groups. Ten subjects discontinued the study. Of 70 subjects, 32 received 10mg alendronate daily and the remaining subjects received placebo. At 1 year, BMD in the alendronate-treated group had increased from baseline by 9.2%, 4.6%, and 3.1% at lumbar spine, femoral neck, and distal forearm, respectively. These percentages were greater than those in controls (4.1%, 0.6%, and 1.0%, respectively). Urinary N-terminal telopeptide (NTx)-I and serum C-terminal telopeptide (CTx)-I levels decreased in both groups after 6 months of treatment. However, more reduction was demonstrated in the alendronate-treated group (71.9% vs. 28.4%, P 0.01, and 84.7% vs. 33.1%, P 0.01, respectively). Compliance with treatment and drug tolerability were good in both alendronate and placebo groups. We concluded that treatment with alendronate 10mg daily for Thai postmenopausal women with osteoporosis significantly increased BMD at all skeletal sites and reduced biochemical markers of bone resorption. It was well tolerated without any serious side effects. 相似文献

The aim of this study was to assess the association of endogenous sex steroids with bone mineral density (BMD) in healthy
postmenopausal women not on hormone therapy. A total of 884 postmenopausal women aged 42–71 years were studied in a cross-sectional
design. Parameters assessed were follicle-stimulating hormone, luteinizing hormone, estradiol, total testosterone, sex hormone-binding
globulin, free estrogen index (FEI), free androgen index (FAI), Δ4-androstendione (Δ4A), dehydroepiandrosterone sulfate (DHEAS),
bone alkaline posphatase, and bone mineral density at the lumbar spine (L-BMD) and femoral neck (N-BMD). Estradiol and FEI
associated positively with both L-BMD and N-BMD (r = 0.21–0.47, P < 0.01). These associations remained significant after adjustment for age, years since menopause, and body mass index. FAI
correlated positively with both L-BMD and N-BMD (r = 0.18 and 0.33, respectively; P < 0.01). At the multivariate analysis, however, FAI remained the significant determinant only for N-BMD. Δ4A associated positively
with N-BMD (r = 0.27, P = 0.001), whereas DHEAS showed no association with BMD at either site. Thus, endogenous steroids are significant determinants
of postmenopausal BMD. Endogenous estradiol may be more important for lumbar spine BMD, whereas endogenous androgens are associated
mainly with femoral neck BMD. 相似文献

目的 基于双能X线骨密度仪测量的身体成分分析,探讨影响绝经后女性骨密度和骨骼肌量的共同因素,为绝经后骨质疏松和肌少症的协同防治提供思路。方法 纳入2015年1月至2020年10月在中山大学附属第一医院进行身体成分分析的171例绝经后女性,根据全身骨密度和相对骨骼肌肉指数(relative skeletal muscle index,RSMI)分为正常组(T值≥-1且RSMI>5.45 kg/m2)、肌少组(T值≥-1且RSMI≤5.45 kg/m2)、骨量异常组(T值<-1且RSMI>5.45 kg/m2)和肌少/骨量异常组(T值<-1且RSMI≤5.45 kg/m2)。采用单因素方差分析比较4组一般资料和身体成分差异,Pearson相关分析研究身体成分与骨密度和RSMI的相关性,多元线性回归分析探索影响骨密度和RSMI的共同因素。结果 4组在体脂率(percent body fat,PBF)、脂肪量(fat mass,FM)、脂肪指数(fat mass index,FMI)、瘦组织(lean mass,LM)、瘦组织指数(lean mass index,LMI)、骨矿盐含量(bone mineral content,BMC)、Android/Gynoid区域脂肪比率和休止代谢率(resting metabolic rate,RMR)的整体比较中差异均有统计学意义(P<0.05)。调整混杂因素后,PBF、FM、FMI与骨密度和RSMI呈不同程度负相关,LM、LMI、BMC、RMR与骨密度和RSMI呈正相关。多元线性回归显示高PBF、低LM和低BMC是骨密度和RSMI的共同危险因素。结论 绝经后女性骨密度与骨骼肌量变化密切相关,针对影响二者的共同危险因素采取干预措施可能有利于绝经后骨质疏松和肌少症的协同防治。 相似文献
