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. 相似文献

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。 相似文献

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. 相似文献

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 总被引:3,自引:0,他引:3
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. 相似文献

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. 相似文献

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。 相似文献

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
