广州天河社区绝经后妇女血清25羟维生素D水平与骨密度的相关性分析

目的调查广州天河区绝经后妇女维生素D水平及其与骨密度的关系。方法随机选取2015年4月至2015年8月在广州市天河区前进街社区卫生服务中心体检的109名绝经后妇女,年龄49~75岁。检测血清25(OH)D水平,分析血清25(OH)D水平与骨转换指标和骨密度(BMD)的相关性。结果 25.7%的受试者血清25(OH)D水平≥75 nmol/L,41.3%在50~75 nmol/L之间,33.0%低于50 nmol/L。双变量分析显示血清25(OH)D水平与血清PINP、β-CTX水平无相关性。股骨颈BMD与血清25(OH)D正相关(r=0.373,P=0.030),校正年龄和体重指数(BMI)后,相关性仍存在(r=0.174,P=0.049)。多元回归分析显示年龄、BMI、25(OH)D是股骨颈BMD的预测因子(R2=0.325)。结论绝经后女性广泛存在血清25(OH)D不足或缺乏,血清25(OH)D水平与股骨颈BMD正相关,适当补充维生素D对维持股骨颈区域的骨量至关重要。

绝经后女性骨密度与维生素D和高密度脂蛋白水平相关性研究

目的探索绝经后妇女血清维生素D水平与高密度脂蛋白(high-density lipoprotein,HDL)和骨密度(bone mineral density,BMD)之间的关系。方法 2015年1月至2018年2月在我院病房及门诊就诊的244名绝经后妇女参加了这项横断面研究,她们都没有服用骨质疏松药物,也没有患任何慢性疾病。采用双能X射线吸收测定法用于评估髋部、股骨颈和腰椎(L_(1～4))的BMD。每个人根据世界卫生组织骨质疏松症标准在至少一个骨骼区域进行分类。在数据收集结束时,测量所有参与者的血脂谱和维生素D水平。维生素D血清水平低于30 ng/mL被定义为维生素D缺乏或不足。结果 27.9%的参与者表现出骨质疏松症。骨质疏松患者的HDL血清水平更高(P0.05)。参与者的低密度脂蛋白、总甘油三酯和总胆固醇水平差异无统计学意义(P0.05)。在未调整年龄、绝经年龄、肥胖和使用抗高血脂药物(他汀类药物)后,HDL水平与腰椎(1～4)、髋部和股骨颈的BMD值和T评分呈显著负相关(P0.05)。在根据维生素D水平对参与者进行分类以及调整混杂因素之后,仅在维生素D缺乏或不足的参与者中观察到HDL水平与三部位的BMD值以及T评分之间呈显著负相关(P0.05)。结论在维生素D缺乏的绝经后妇女中,血清HDL水平与骨骼状态呈负相关。     

未绝经女性甲亢患者血25羟维生素D水平与骨密度的关系

目的 观察未绝经女性甲亢患者骨密度及血钙、血磷、血碱性磷酸酶（ALP）、血浆25羟维生素D[25(OH)D]、血浆甲状旁腺激素（PTH）水平变化,分析未绝经女性甲亢患者血浆25(OH)D与骨密度的关系。方法 选取50例初发或复发的未绝经女性甲亢患者,51例正常对照人群,应用双能X线吸收仪（DXA）测定腰椎1-4、股骨颈、股骨大转子、Ward三角和全股骨的骨密度,电化学发光法测定血浆25(OH)D和PTH,生化法测定血钙、磷、ALP。结果 甲亢组L1、Ward三角骨密度均低于对照组,差异有统计学意义。与对照组相比,甲亢组血钙、血ALP、血浆25(OH)D水平升高,血浆PTH降低,差异均有统计学意义。甲亢组维生素D缺乏17例(34%) , 不足19例(38%) , 充足14例(28%)。对照组维生素D缺乏30例(59%) , 不足18例(35%), 充足3例(6%)。相关分析示,两组血浆25（OH）D与L1、L2、L3、L4、L1-4、股骨颈、股骨大转子、Ward三角、全股骨骨密度均无相关性。Pearson相关分析示,甲亢组血浆25(OH)D与PTH呈负相关（r=-0.378,P<0.01）。结论 未绝经女性甲亢患者L1、Ward三角骨密度降低。未绝经女性甲亢患者血浆25(OH)D升高,可能与高血钙、PTH分泌抑制、高血磷导致1-α-羟化酶活性降低有关。未绝经女性甲亢患者血浆25(OH)D水平与骨密度无直接关系。

Comparison of vitamin D metabolism in early healthy and late osteoporotic postmenopausal women

Summary We studied 20 healthy premenopausal women aged 36.5±4.0 years (mean±1 SD), 123 healthy postmenopausal women aged 50.0±2.4 years, and 103 postmenopausal women aged 65.1±5.6 years with symptomatic osteoporosis (forearm and spinal fracture). Serum levels of vitamin D metabolites [25(OH)D, 24,25(OH)₂D₃, and 1,25(OH)₂D] were compared with (1) bone mass in the forearm (single photon absorptiometry) and in the spine (dual photon absorptiometry); (2) biochemical indices of bone formation (serum alkaline phosphatase, plasma bone Gla protien), and bone resorption (fasting urinary hydroxyproline); and (3) other biochemical estimates of calcium metabolism (serum calcium, serum phosphate, 24-hour urinary calcium, intestinal absorption of calcium). The present study revealed no difference in any of the vitamin D metabolites between the premenopausal women, the healthy postmenopausal women and the osteoporotic women as a group. The concentrations of 1,25(OH)₂D and 25(OH)D were significantly lower in patients with spinal fracture than in those with forearm fracture. In the early postmenopausal women, serum 1,25(OH)₂D was related to forearm bone mass (r=−0.20;P<0.05), intestinal calcium absorption (r=0.18;P<0.05), and 24-hour urinary calcium (r=0.21;P<0.05); serum 25(OH)D was related to spinal bone mass (r=0.23;P<0.01). In the osteoporotic women, serum vitamin D metabolites were not related to bone mass, but 1,25(OH)₂D was related to bone Gla protein (r=0.33;P<0.001), serum phosphate (r=−0.27;P<0.01), and 24-hour urinary calcium (r=0.43;P<0.001). The present study demonstrates that in a population that is apparently not deficient in vitamin D, a disturbance of the vitamin D metabolism is not likely to play a pathogenetic role in early postmenopausal bone loss. Patients with spinal fractures have low levels of vitamin D metabolites, which may aggravate their osteoporosis.     

绝经后女性股骨近端骨密度与骨质疏松性骨折相关性研究

目的：研究绝经后女性股骨近端骨密度的变化规律与骨质疏松症、骨质疏松性骨折间的关系。方法采用法国Medlink公司Osteocore 3型双能X线骨密度仪,对本地区417例绝经后女性股骨颈、大转子、粗隆间、全髋进行骨密度测定。结果骨折组各年龄段、各部位的BMD均比非骨折组低（ P＜0．05）。随着年龄的增长,股骨近端骨量逐渐丢失,除了45～50组,其余各年龄段骨折组的患病率明显高于非骨折组（ P＜0．05）,骨密度值越低,骨折危险性越大。结论绝经后女性股骨近端骨密度与发生骨质疏松性骨折的风险呈明显负相关性,应该注意预防。     

The relationship of vitamin D status to bone mineral density in an Italian population of postmenopausal women

Several authors have found a relationship between vitamin D status and bone mineral density (BMD). To our knowledge, no previous studies on this topic have been carried out on the Italian postmenopausal population. We studied this relationship retrospectively in 156 Italian postmenopausal women. We also investigated the relationship between parathyroid hormone (PTH) and BMD. Measurements of BMD were taken at the lumbar spine and upper femur by dual X-ray absorptiometry. Serum 25(OH)D (calcidiol), 1,25(OH)2D (calcitriol), PTH, calcium, phosphorus, creatinine, osteocalcin and urinary calcium and phosphorus were measured according to the current laboratory methods of analysis. We found a positive statistically significant correlation between BMD, both at the spine and hip, and 25(OH)D, and a negative statistically significant correlation between BMD and PTH. No statistically significant correlation was found between BMD and 1,25(OH)2D. Crude logistic regression showed age, 25(OH)D and PTH were significant predictors of low BMD, while 1,25(OH)2D was not. Backward logistic regression showed 25(OH)D was the best predictive model for spine osteoporosis together with age, and on its own it was the best predictive model for femoral neck osteoporosis.No funding sources supported this publication.     

DXA、QCT和SPA方法测量47例绝经后妇女骨质疏松症的比较

以骨密度测量应用最广的３种方法（ＤＸＡ─双能ｘ线吸收法，ＱＣＴ─定量ＣＴ法和ＳＰＡ─单光子吸收法）测量绝经后妇女的骨矿密度，比较其测量值、诊断结果和相关关系。首先用ＳＰＡ法测量绝经后妇女１８１例，诊断骨质疏松（ＯＰ）４７例。三种方法测量骨矿密度的均值分别低于峰值骨量的Ｍ─２ｓ的９％、２１．４％和２１％，且ＤＸＡ和ＱＣＴ两种方法测量的均值都在骨折阈值范围内。ＤＸＡ和ＱＣＴ诊断４７例ＯＰ之间无显著性差异，当排除椎骨骨质增生后的ｘ２＝０．２３７，且ＤＸＡ和ＱＣＴ测量值之间为正相关，ｒ＝０．７９９，而ＤＸＡ、ＱＣＴ和ＳＰＡ之间的相关系数，ｒ＝０．１８５和０．２８５，ＤＸＡ诊断ＯＰ的敏感性为８６．６％，特异性为７０％。     

Effect of combined administration of vitamin D3 and vitamin K2 on bone mineral density of the lumbar spine in postmenopausal women with osteoporosis

The effect of the combined administration of vitamin D₃ and vitamin K₂ on bone mineral density (BMD) of the lumbar spine was examined in postmenopausal women with osteoporosis. Ninety-two osteoporotic women who were more than 5 years after menopause, aged 55–81 years, were randomly divided into four administration groups: vitamin D₃ (1α hydroxyvitamin D₃, 0.75 μg/day) (D group; n = 29), vitamin K₂ (menatetrenone, 45 mg/day) (K group; n = 22), vitamin D₃ plus vitamin K₂ (DK group, n = 21), and calcium (calcium lactate, 2 g/day) (C group; n = 20). BMD of the lumbar spine (L2–L4) was measured by dual energy X-ray absorptiometry at 0, 1, and 2 years after the treatment started. There were no significant differences in age, body mass index, years since menopause, and initial BMD among the four groups. One-way analysis of variance (ANOVA) with repeated measurements showed a significant decrease in BMD in the C group (P < 0.001). Two-way ANOVA with repeated measurements showed a significant increase in BMD in the D and K groups compared with that in the C group (P < 0.05 and P < 0.001, respectively), and a significant increase in BMD in the DK group compared with that in the C, D, and K groups (P < 0.0001, P < 0.05 and P < 0.01, respectively). These findings indicate that combined administration of vitamin D₃ and vitamin K₂, compared with calcium administration, appears to be useful in increasing the BMD of the lumbar spine in postmenopausal women with osteoporosis.

The relationship between bone mineral density and ultrasound in postmenopausal and osteoporotic women

The aim of this cross-sectional study was to use a novel method of data analysis to demonstrate that patients with osteoporosis have significantly lower ultrasound results in the heel after correcting for the effect of bone mineral density (BMD) measured in the spine or hip. Three groups of patients were studied: healthy early postmenopausal women, within 3 years of the menopause (n=104, 50%), healthy late postmenopausal women, more than 10 years from the menopause (n=75, 36%), and a group of women with osteoporosis as defined by WHO criteria (n=30, 14%). Broadband ultrasound attenuation (BUA), speed of sound (SOS) and Stiffness were measured using a Lunar Achilles heel machine, and BMD of the lumbar spine and left hip was measured using dual-energy X-ray absorptiometry (DXA). SOS, BUA and Stiffness were regressed against lumbar spine BMD and femoral BMD for all three groups combined. The correlation coefficients were in the range 0.52–0.58, in agreement with previously published work. Using a calculated ratio R, analysis of variance demonstrated that the ratio was significantly higher in the osteoporotic group compared with the other two groups. This implied that heel ultrasound values are proportionately lower in the osteoporotic group compared with the other two groups for an equivalent value of lumbar spine and femoral neck BMD. We conclude that postmenopausal bone loss is not associated with different ultasound values once lumbar spine or femoral neck BMD is taken into account. Ultrasound does not give additional information about patterns of bone loss in postmenopausal patients but is important in those patients with osteoporosis and fractures.     

Associations of polymorphisms in the vitamin D receptor gene (BsmI and FokI) with bone mineral density in postmenopausal women in Malta

Previous studies have suggested that variations in the vitamin D receptor (VDR) gene are related to bone mineral density (BMD). In this study, the TC transition in the start codon and the GA polymorphism at the 3 end of the VDR gene, identified by endonucleases FokI and BsmI, respectively, were analysed and correlated with BMD in postmenopausal Maltese women (n=104). Genotype frequencies observed for the VDR start codon polymorphism (SCP) were CC: 60.4%; CT: 30.7% and TT: 8.9%, while those observed for the 3 in this study were GG: 16.4%; GA: 51.9%; AA: 31.7%. In postmenopausal women, both lumbar and femoral BMD were observed to be highest in CC homozygotes for the FokI genotype and in GG homozygotes for the BsmI genotype, although in both groups the difference between the genotypes was not statistically significant, even after adjusting BMD for age, BMI and years since menopause. No evidence of linkage disequilibrium between the two alleles was observed.     

绝经后妇女膝关节骨性关节炎与骨质疏松症的相关性研究

目的探讨绝经后妇女膝关节骨性关节炎与骨质疏松症的相关性。方法对134例绝经后妇女膝关节骨性关节炎患者行年龄、体重、身高及体重指数的计算和骨密度的测定。行双膝关节负重正位X线拍片,按照骨关节炎Kellgren分级标准将骨性关节炎患者分为4级,根据患者的临床症状和X线表现不同把4级骨性关节炎分成轻度组和重度组。分析膝关节骨性关节炎与其伴发的骨质疏松症的相关性。结果绝经后妇女患者的骨密度与年龄呈负相关,与体重、身高及体重指数呈正相关。重度组和轻度组相比较在身高、体重及体重指数上无显著性差异(P0.05),在年龄与股骨颈骨密度上有极显著性差异(P0.01)。股骨颈骨密度线性回归分析表明年龄对股骨颈骨密度的影响较大,因此用协方差分析排除年龄混杂因素对股骨颈骨密度的影响,重度组和轻度组在股骨颈骨密度上仍有显著性差异(P0.05)。结论绝经后妇女骨质疏松症与膝关节骨性关节炎的严重程度密切相关,膝关节骨性关节炎越严重,骨密度越低。骨性关节炎可能是骨质疏松症发生或加重的危险因素之一。     

绝经后女性骨质疏松性椎体骨折与腰椎体骨密度的相关性

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。
