The purpose of the present study was to compare the effects of etidronate and menatetrenone on bone mineral density (BMD)
and the incidence of vertebral fractures in postmenopausal women with osteoporosis. Seventy-two osteoporotic women, more than
5 years after menopause, 53–78 years of age, were randomly divided into three administration groups: E group; intermittent
cyclical etidronate (200 mg/day, 14 days per 3 months; n = 25); M group; menatetrenone (45 mg/day, daily; n = 23); and C group (control); calcium lactate (2 g/day, daily; n = 24). Forearm BMD was measured by dual-energy X-ray absorptiometry at 0, 6, 12, 18, and 24 months after the treatment started.
There were no significant differences in age, body mass index, years since menopause, and initial BMD among the three groups.
One-way analysis of variance (ANOVA) with repeated measurements showed a significant decrease in BMD in the C group (P < 0.0001). Two-way ANOVA with repeated measurements showed a significant increase in BMD in the M group compared with that
in the C group (P < 0.0001), and a significant increase in BMD in the E group compared with that in the C and M groups (P < 0.0001 and P < 0.01, respectively). The indices of new vertebral fractures/1000 patient-years in the E and M groups were significantly
higher than that in the C group (χ2 = 47.7; P < 0.0001 and χ2 = 42.4; P < 0.0001, respectively), and did not differ significantly between the E and M groups. The present preliminary study provides
evidence to suggest that, despite the lower increase in BMD produced by me-natetrenone, this agent, as well as etidronate,
may have the potential to reduce osteoporotic vertebral fractures in postmenopausal women with osteoporosis.

The purpose of the present open-labeled, randomized, prospective study was to compare the effects of cyclical etidronate combined with alfacalcidol with those of cyclical etidronate alone on lumbar bone mineral density (BMD), bone resorption, and back pain in postmenopausal women with osteoporosis. Forty postmenopausal women with osteoporosis, 60–86 years of age, without any vertebral fractures in the lumbar spine, were randomly divided into two groups with 20 patients in each group. One group was treated with cyclical etidronate (oral etidronate 200mg daily for 2 weeks every 3 months) and the other was given cyclical etidronate combined with alfacalcidol (cyclical etidronate plus alfacalcidol 1Ìg daily continuously). The BMD of the lumbar spine (L1–L4) measured by dual-energy X-ray absorptiometry, urinary crosslinked N-terminal telopeptides of type I collagen (NTX) measured by an enzyme-linked immunosorbent assay, and back pain evaluated by the face scale score were assessed at baseline, 6 months, and 12 months. There were no significant differences in baseline characteristics including age, body mass index, years since menopause, lumbar BMD, urinary NTX level, and face scale score between the two treatment groups. Both treatments significantly reduced the urinary NTX level and back pain. Cyclical etidronate combined with alfacalcidol significantly increased the lumbar BMD with a more significant reduction in the urinary NTX level than cyclical etidronate alone, but cyclical etidronate alone did not significantly increase the lumbar BMD. Alleviation of back pain was similar in the two groups. These results suggest that cyclical etidronate combined with alfacalcidol appears to be more useful than cyclical etidronate alone for increasing the lumbar BMD by more markedly suppressing bone resorption in postmenopausal women with osteoporosis. 相似文献

Although osteoporosis in men is already a major public health problem, there is still a dearth of data about the effects of
risedronate in male osteoporosis, especially in Japanese with primary osteoporosis. Therefore, the objective of our study
was to investigate the effects of risedronate on bone mineral density (BMD), bone turnover, back pain, and fractures in these
patients prospectively for two years (at baseline, three months, six months, twelve months, and twenty-four months) both longitudinally
and compared with those of alfacalcidol. The subjects enrolled for this study were 66 Japanese male patients with untreated
primary osteoporosis (mean age 63.52 ± 8.7 years), who were divided into two groups (44 with risedronate and 22 with alfacalcidol).
We measured BMD by dual energy X-ray absorptiometry at three sites—the lumbar spine, femoral neck, and distal radius. Risedronate
treatment significantly increased BMD at the lumbar spine and at the femoral neck, reduced bone-specific alkaline phosphatase
(BAP) and serum N-terminal telopeptide of type I collagen (NTx), and reduced back pain, both longitudinally and compared with
alfacalcidol treatment. We observed a lower rate of incident fracture in risedronate users. However, multiple logistic regression
analysis revealed that this trend was not statistically significant, possibly because of the small number of patients enrolled.
These potentially beneficial effects of risedronate on bone in male patients with primary osteoporosis suggest the possibility
that osteoporosis should be treated with risedronate regardless of gender in order to effectively prevent subsequent osteoporotic
fractures. 相似文献

To test the hypothesis that the association between bone mineral density (BMD) and estimated volumetric BMD and prevalent vertebral fractures differs in men and women, we studied 317 Caucasian men and 2,067 Caucasian women (average age 73 years). A total of 43 (14%) men and 386 (19%) women had a vertebral fracture identified on lateral spine radiographs using vertebral morphometry. Hip and spine areal BMD was about 1/3 standard deviation lower among men and women with a vertebral fracture. A 0.10 g/cm2 decrease in areal BMD was associated with 30–40% increased odds of having a fracture in men and 60–70% increased likelihood in women. Low bone mineral apparent density (BMAD) was also associated with 40–50% increased odds of a vertebral fracture in both genders. The probability of a man having a fracture was observed at higher absolute areal BMD values than observed for women (P=values for interaction of BMD × gender: trochanter, P=0.05; femoral neck, P=0.10; total hip, P=0.09). In contrast, the probability of fracture was similar in men and women across the range of estimated volumetric BMD (BMAD). In conclusion, low BMD and low BMAD are associated with increased odds of vertebral fracture in both men and women. Measures of bone mass that partially correct for gender differences in bone size may yield universal estimates of fracture risk. Prospective studies are needed to confirm this observation. 相似文献

Effect of exercise training and detraining on bone mineral density in postmenopausal women with osteoporosis 总被引:9,自引:0,他引:9
We examined the effect of exercise training and detraining on bone mineral density (BMD) in postmenopausal women with osteoporosis.
Thirty-five postmenopausal women with osteoporosis, aged 53–77 years, were randomly assigned to three groups: a control group
(n = 20), a 2-year exercise training group (n = 8), and an 1-year exercise training plus 1-year detraining group (n = 7). Exercise training consisted of daily brisk walking and gymnastic training. Calcium lactate, 2.0 g, and 1α-hydroxyvitamin
D3, 1 μg were supplied daily to all subjects. No significant differences in initial lumbar BMD, measured by dual-energy X-ray
absorptiometry (DXA) were found among the three groups. The mean percent change in BMD compared with the baseline was significantly
higher at 1 and 2 years in the exercise training group and at 1 year in the detraining group than in the control group, and
did not differ significantly at 2 years between the detraining and control groups. These findings indicate that our exercise
training program led to a significant increase in lumbar BMD in postmenopausal women with osteoporosis compared with the control,
but that the BMD reverted toward a level that was not significantly different from the control with detraining. Continued
exercise training is needed to maintain the bone mass gained through exercise training.

目的定量分析腰椎旋转角度对双能X线法(Dual-energy X-ray absorptiometry,DXA)测量腰椎骨密度值(Bone mineral density,BMD)的影响,并提出校正方法。方法模拟腰椎BMD标准测量方法,将5具成年男性腰椎标本放于特制的可旋转模具上。以5°为增加量,将标本从0°(标准前后位)逐渐旋转至45°,测量不同旋转角度状态下的腰椎BMD。同时,对标本进行X线摄片,根据Nash-Moe法评估椎体的旋转程度,并与DXA获得的图像进行比较。结果随着腰椎旋转角度增加,腰椎的投射面积逐渐增加,骨矿含量无显著性变化,骨密度值逐渐降低。相关性分析表明,腰椎旋转角度与投射面积呈正性相关,与BMD呈负性相关。当旋转度数至15°时,测量BMD值与0°值之间有显著性差异(P=0.001)。当旋转至45°时,BMD降低达21%。根据Nash-Moe法判断腰椎旋转程度,DXA法与X线法的符合率为90%。结论椎体旋转角度对腰椎骨密度值具有显著性影响,可以导致测量值较真实值偏低。对于存在腰椎旋转畸形患者,应当根据旋转角度校正骨密度,以避免过高估计患者骨质疏松严重程度。 相似文献

The purpose of this study was to determine whether early changes in the urinary levels of cross-linked N-terminal telopeptides of type I collagen (NTX) during alendronate treatment would be correlated with the 1-year response of lumbar bone mineral density (BMD) in postmenopausal Japanese women with osteoporosis. One hundred five postmenopausal women with osteoporosis, aged 54–88 years, were treated with alendronate (5mg daily) for 12 months. The urinary NTX levels were measured by enzyme-linked immunosorbent assay at the baseline and at 3, 6, and 12 months, and lumbar (L1–L4) BMD was measured by dual-energy X-ray absorptiometry using the Hologic QDR 1500W equipment at the baseline and at 12 months. The mean percent reduction in urinary NTX level at 3, 6, and 12 months was 36.8%, 49.5%, and 49.0%, respectively, the extent of reduction at 6 and 12 months being greater than that at 3 months, and the mean percent increase of the lumbar BMD at 12 months was 8.2%. Single regression analysis showed a significant correlation between the percent reductions in the urinary NTX level at 3, 6, and 12 months of treatment and the percent increase of the lumbar BMD at 12 months (r = 0.200, P < 0.05; r = 0.341, P < 0.001; and r = 0.338, P < 0.001, respectively). Thirty percent of the patients were labeled as poor responders at 3 months, with the reduction in the urinary NTX level being less than the minimum significant change (MSC); 61% of these patients showed a greater reduction in the urinary NTX level, exceeding the MSC, at 6 months. These results suggest that the changes in the urinary NTX levels at 3 and 6 months after the start of alendronate treatment at the dose of 5mg daily may be correlated with the 1-year response of the lumbar BMD in postmenopausal Japanese women with osteoporosis. In other words, the greater the reduction of the urinary NTX level at 3 and 6 months after the start of alendronate treatment, the greater can be the expected increase of the lumbar BMD after 12 months of treatment. In this study, 70% of the patients were good responders, who showed a reduction of the urinary NTX level exceeding the MSC at 3 months. Among the remaining 30% poor responders, about 60% showed satisfactory reduction of the urinary NTX level, exceeding the MSC, at 6 months after the start of treatment with alendronate. 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.

Stronger back muscles reduce the incidence of vertebral fractures: a prospective 10 year follow-up of postmenopausal women 总被引:12,自引:0,他引:12

The long-term protective effect of stronger back muscles on the spine was determined in 50 healthy white postmenopausal women, aged 58–75 years, 8 years after they had completed a 2 year randomized, controlled trial. Twenty-seven subjects had performed progressive, resistive back-strengthening exercises for 2 years and 23 had served as controls. Bone mineral density, spine radiographs, back extensor strength, biochemical marker values, and level of physical activity were obtained for all subjects at baseline, 2 years, and 10 years. Mean back extensor strength (BES) in the back-exercise (BE) group was 39.4 kg at baseline, 66.8 kg at 2 years (after 2 years of prescribed exercises), and 32.9 kg at 10 years (8 years after cessation of the prescribed exercises). Mean BES in the control (C) group was 36.9 kg at baseline, 49.0 kg at 2 years, and 26.9 kg at 10 years. The difference between the two groups was still statistically significant at 10 year follow-up (p = 0.001). The difference in bone mineral density, which was not significant between the two groups at baseline and 2 year follow-up, was significant at 10 year follow-up (p = 0.0004). The incidence of vertebral compression fracture was 14 fractures in 322 vertebral bodies examined (4.3%) in the C group and 6 fractures in 378 vertebral bodies examined (1.6%) in the BE group (chi-square test, p = 0.0290). The relative risk for compression fracture was 2.7 times greater in the C group than in the BE group. To our knowledge, this is the first study reported in the literature demonstrating the long-term effect of strong back muscles on the reduction of vertebral fractures in estrogen-deficient women. 相似文献

The purpose of this study was to investigate whether it is possible to predict the long-term effects of estrogen replacement therapy (ERT) on lumbar bone mineral density (BMD) of oophorectomized women based on changes in BMD. In this study, we retrospectively investigated the changes in lumbar BMD of 70 oophorectomized women under ERT for more than 10 years, and examined whether it was possible in the early stage of ERT to predict the amount of lumbar BMD based on various parameters. Seventy oophorectomized Japanese women (56.8±3.9 years old) treated with conjugated equine estrogen (oral) at a dosage of 0.625 mg/day for 10 years were enrolled. Lumbar (L2–L4) BMD was measured annually by dual-energy X-ray absorptiometry (DXA; CV<1.0%). The correlation between changes in BMD after 10 years on ERT (BMD10) and several clinical factors was examined using a stepwise multiple regression model. The change in BMD after 1 year on ERT (%BMD1) was the only independent factor that correlated with changes in BMD after 10 years on ERT; the coefficient of correlation was R
2=0.557 (R=0.750, P<0.001). Based on the %BMD1, the 70 women were divided into two groups: women with a positive change in the 1st year (%BMD10%) in group A (n=40) and those with a negative value in the first year ( %BMD1<0%) in group B (n=30). We investigated the sensitivity and specificity in the coincidence of %BMD1 changes in BMD after 10 years on ERT. The %BMD1 coincided with changes in BMD after 10 years on ERT; the sensitivity was 92.5% and specificity was 70.0%. In conclusion, changes in lumbar BMD on ERT can be predicted from the changes in lumbar BMD at the end of the 1st year. 相似文献

A case of osteogenesis imperfecta (OI) that was successfully treated with oral etidronate and alfacalcidol is reported. A 36-year-old man with OI type I who had frequently been experiencing fragile fractures in the long bones of the upper and lower extremities presented to our hospital with back pain caused by fragile thoracic vertebral fractures. He was treated with intermittent cyclical etidronate (200 mg/day for 2 weeks per 3 months) and alfacalcidol (1 microgram/day, daily) over 18 months. The bone mineral density of the lumbar spine (L1-L4) measured by dual-energy X-ray absorptiometry (Hologic QDR 1500 W) increased over 18 months, and back pain due to thoracic vertebral fractures markedly decreased. No new fragile vertebral or nonvertebral fractures were observed during the 18 months of treatment. This report provides evidence indicating that treatment with intermittent cyclical oral etidronate and alfacalcidol has potential use in adult patients with OI type I. 相似文献

Calcium-sensing receptor (CaSR) is an attractive candidate gene for osteoporosis susceptibility. The CaSR “A986S” genotype has been shown to have an effect on serum calcium. Recently, an association has been reported between the CaSR gene A986S polymorphism and bone mineral density in healthy white girls. In this study, we examined whether CaSR gene A986S polymorphism is associated with decreased bone mass in 230 Hungarian postmenopausal women. From this cohort, 108 osteoporotic patients were compared with 122 healthy control women. Bone mineral density (BMD) was measured at the lumbar spine (L2–4) and femoral neck using dual-energy X-ray absorptiometry. Allele-specific polymerase chain reaction was used to amplify A986S polymorphisms of the CaSR gene. We found no difference in the distribution of different alleles or genotypes between groups (p = 0.762). No significant effect of CaSR genotype on BMD was observed either in the whole population or in the subgroups. Our data do not support the idea that CaSR gene A986S polymorphism has an impact on bone mass. 相似文献

Summary To evaluate the incidence of new and/or progressive vertebral deformities and changes in bone mineral density, we re-examined
66 patients with sarcoidosis after a follow-up period of four years. In 17 subjects (26%) new and/or progressive vertebral
deformities were found, though BMD did not change significantly.
Introduction Previous studies from our group have shown that morphometric vertebral deformities suggestive of fractures can be found in
20% of patients with sarcoidosis, despite a normal bone mineral density (BMD). The aim of this study was to determine the
incidence of new and/or progressive vertebral deformities and the evolution of BMD during the course of this disease.
Methods BMD of the hip (DXA) and vertebral fracture assessment (VFA) with lateral single energy densitometry was performed at baseline
and after 45 months in 66 patients with sarcoidosis. Potential predictors of new/progressive vertebral deformities were assessed
using logistic regression analysis.
Results The BMD of the total group was unchanged after follow-up. The prevalence of vertebral deformities increased from 20 to 32%
(p < 0.05); in 17 subjects (26%) new or progressive vertebral deformities were diagnosed. A lower T-score of the femoral neck
[(OR = 2.5 (CI: 1.0-5.9), p < 0.05)] and mother with a hip fracture [(OR = 14.1 (CI:1.4-142.6), p < 0.05)] were independent predictors of new/progressive deformities.
Conclusions In subjects with sarcoidosis the number of vertebral deformities increases in the course of this disease, despite unchanged
BMD. The combination of low normal BMD and family history of fragility fractures confers an increased risk of the incidence
of these deformities. 相似文献

Summary One hundred and twelve postmenopausal women with low bone mineral density (BMD) and forearm fractures were randomized to physical
training or control group. After one year the total hip BMD was significantly higher in the women in the physical training
group. The results indicate a positive effect of physical training on BMD in postmenopausal women with low BMD.
Introduction The fivefold increase in hip fracture incidence since 1950 in Sweden may partially be due to an increasingly sedentary lifestyle.
Our hypothesis was that physical training can prevent bone loss in postmenopausal women.
Methods One hundred and twelve postmenopausal women 45 to 65 years with forearm fractures and T-scores from −1.0 to −3.0 were randomized
to either a physical training or control group. Training included three fast 30-minute walks and two sessions of one-hour
training per week. Bone mineral density (BMD) was measured in the hip and the lumbar spine at baseline and after one year.
Results A per protocol analysis was performed, including 48 subjects in the training group and 44 subjects in the control group. The
total hip BMD increased in the training group +0.005 g/cm2 (±0.018), +0.58%, while it decreased −0.003 g/cm2 (±0.019), −0.36%,
(p = 0.041) in the control group. No significant effects of physical training were seen in the lumbar spine. A sensitivity intention
to treat analysis, including all randomized subjects, showed no significant effect of physical training on BMD at any site.
Conclusions The results indicate a small but positive effect of physical exercise on hip BMD in postmenopausal women with low BMD. 相似文献

Health-related quality of life (HRQOL) in postmenopausal women with osteoporosis has hitherto been mainly assessed in patients with clinically recognized vertebral fractures. Our study aimed to investigate the QOL perception in 361 asymptomatic ambulant postmenopausal women who came to our center for an osteoporosis screening program planned with their general practitioners. The Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO) was administered to all subjects. The participants underwent bone mineral density (BMD) measurements by DXA of either the lumbar spine and/or the femoral neck, as well as X-ray examination of the thoracolumbar spine to identify subclinical vertebral fractures. According to the WHO definition, where subjects are subdivided by BMD values into three groups (women with normal BMD, osteopenia, and osteoporosis), a significant difference was found only for the domains which explore general health perception (p<0.01 by ANOVA) and mental function (p<0.001 by ANOVA). When we segregated both osteopenic and osteoporotic women according to whether or not they had vertebral fractures, a significant difference was found only in osteoporotic patients for domains which explore physical function (p<0.001), social function (p<0.001), general health perception (p<0.02), and total QUALEFFO score (p<0.01). Stepwise multiple logistic regression analysis of the whole sample showed that both vertebral fractures and a low femoral BMD impairs QOL perception, while age did not exert a significant influence. ROC curves analysis demonstrated a low discriminating capacity of individual domains and total QUALEFFO score for both vertebral deformities and BMD categorization. Our results showed that QUALEFFO is not able to discriminate between patients with or without subclinical vertebral fractures. However, some aspects of QOL appear to be impaired in patients with subclinical vertebral fractures or reduced BMD. 相似文献
