强直性脊柱炎患者血清TNF-a、BGP和CTX水平与骨密度的关系 总被引:3,自引:0,他引:3
目的探讨强直性脊柱炎(AS)患者骨质疏松(OP)的发病机制。方法分别测定36例男性AS患者血清肿瘤坏死因子-a(TNF-a)、骨钙素(BGP)I、-型胶原C末端肽(CTX)水平及腰椎和股骨颈的骨密度(BMD)值,并与20例健康者对照。结果AS早期腰椎和股骨颈BMD均低于对照组,晚期股骨颈BMD更低于对照组。AS血清TNF-a、CTX水平较对照组显著增高(P<0.01;P<0.05),而血清BGP水平较对照组无显著差差异(P>0.05)。AS患者中OP组TNF-a、CTX水平较NOP组显著增高(P<0.01;P<0.05),OP组中血清TNF-a与CTX呈正相关,与股骨颈密度呈负相关;与BGP无明显相关性。结论AS患者主要是由于骨吸收增加而导致骨质疏松的发生。血清TNF-α水平的增高可促进骨吸收加强,是AS骨质疏松的重要原因之一。降低血清TNF-a水平,对AS患者骨质疏松的防治可能有积极的意义。 相似文献

目的了解中老年女性骨转换指标变化对骨密度(BMD)和骨质疏松患病风险的影响。方法 632名健康中老年女性(年龄40~89岁),测定空腹血清骨特异性碱性磷酸酶(BAP)、骨钙素(OC)、骨I型胶原C-末端肽(s CTX)和N-末端肽(s NTX),以及腰椎和近端股骨骨密度(BMD),并分析这些骨转换指标与BMD和骨质疏松患病风险的关系。结果本研究检测的各种骨转换指标与腰椎、股骨颈和髋部BMD呈显著负相关(r=-0.238~-0.528,P均=0.000)。调整年龄、身高、体重和体重指数后,血清BAP、OC和s CTX与腰椎和股骨颈BMD的偏相关系数仍然有显著性意义。多元线性回归分析显示,这些骨转换指标对腰椎BMD是一个有意义的负性决定因素,大约可以解释腰椎BMD 7.6%~27.9%的变异性。各种骨转换指标水平最高的四分位组(Q4)与最低的组(Q1)比较,腰椎、股骨颈和髋部的骨质疏松患病风险,分别显著增加4.6~15倍(OR=4.6~15,95%CI:2.6~30),3.2~13倍(OR=3.2~13,95%CI:1.5~36)和3.0~13倍(OR=3.0~13,95%CI:1.3~44)。结论本研究揭示了中老年女性骨转换指标与BMD和骨质疏松患病风险的关系,提示骨转换指标水平变化是中老年女性BMD的重要决定因素,骨形成指标和/或骨吸收指标水平增加者骨质疏松患病率和患病风险大大增加。 相似文献

Relation of axial bone mass to habitual calcium intake and to cortical bone loss in healthy early postmenopausal women 总被引:2,自引:0,他引:2
A group of 60 healthy early postmenopausal women participating in an ongoing study on the effect of habitual calcium intake on the rate of cortical bone loss at the radius, were subjected to additional skeletal measurements at the lumbar spine and femoral neck. The women were between 58 and 64 years of age, and 3 to 10 years postmenopausal. No correlations were found between habitual calcium intake (range 560 to 2580 mg/day) and either bone mineral content of the radius, the lumbar spine and the femoral neck, or spine deformity index. Body mass index was found to be positively correlated with bone mass indices of the radius (decrease of BMD and BMD) and femoral neck (BMC), but not with of the lumbar spine (BMC, BMD and SDI), even after adjustments had been made for confounding factors. Although the rate of cortical bone loss at the radius correlated significantly with bone mineral content of lumbar spine and femoral neck, the error in predicting bone mass of the lumbar spine or the femoral neck from longitudinal measurements of cortical bone at the radius was high. The rate of cortical bone loss did not correlate with the spine deformity index. We conclude that in healthy women in early menopause, the bone mineral content of both the appendicular and the axial skeleton are not influenced by habitual calcium intake. A higher body mass index has a protective effect on the appendicular skeleton but appears to be less protective to the axial skeleton. Longitudinal measurements of cortical bone mass are of limited value to predict bone density of the appendicular and axial skeleton. 相似文献

The relationship between vitamin D and bone density was studied in 150 selected, mature (45–74), postmenopausal women with a lumbar spine Z score below 0. Vitamin D status was evaluated using calcidiol serum levels. Serum calcitriol and parathyroid hormone (PTH) values were also evaluated in some subjects. Bone mass was evaluated by ascertaining bone density and Z and T scores in the lumbar spine and femur region. The reference group consisted of 25 premenopausal women. The postmenopausal group was divided into subgroups according to age, i.e., under or over 60 years old. Additionally, the whole group was also subdivided according to their lumbar spine Z scores into group I (Z>-1), group II (Z<-1; >-2), and group III (Z<-2). Group III of postmenopausal women had higher PTH and lower calcitriol levels than premenopausal women. Calcidiol serum levels were lower in postmenopausal women groups II or III than in the group I and premenopausal women. Calcidiol serum levels and the bone mass values for the lumbar spine were correlated positively in all the postmenopausal women; in the women over 60 years of age, calcidiol levels also correlated with the bone mass values expressed as the bone density in three femur regions: femoral neck, trocanter, and Ward's triangle. In conclusion, mature postmenopausal woman showed high PTH levels and low calcidiol and calcitriol values. Calcidiol status is significantly related to bone mineral density in the lumbar spine and in women over 60 years, calcidiol levels also correlated with bone density in the femur regions. 相似文献

The relationship between osteoarthritis of the hands,bone mineral density,and osteoporotic fractures in elderly women 总被引:6,自引:0,他引:6
Dr C. Marcelli F. Favier P. O. Kotzki V. Ferrazzi M. -C. Picot L. Simon 《Osteoporosis international》1995,5(5):382-388
To study the relationship between osteoarthritis (OA) and osteoporosis (OP), radiographic osteoarthritis lesions of the hands (HOA) were quantified in 300 healthy women, aged 75 years or more, as a subgroup of a cohort originally recruited for a multi-centre study of risk factors for femoral neck fracture. The HOA combined score (i.e. the sum of the grades of joint-space narrowing, osteophytes, erosions and joint misalignment), the osteophytosis score and the joint-space narrowing score were calculated on a radiograph of both hands. Bone mineral density (BMD) was measured using dual-energy X-ray absortiometry (Lunar DPX) at the femoral neck, Ward's triangle and the total body. BMDs of the total spine, lumbar spine, and the upper and lower limbs were derived from the regional analyses of the total body measurement. Correlations between bone mass, HOA scores and other variables were explored by multiple linear regression and stepwise logistic regression analysis. The HOA combined score was positively correlated with increasing age but not with body mass index. In the multiple regression analyses the HOA combined score positively correlated with BMD at all sites, except the femoral neck and Ward's triangle; the osteophytosis score correlated with BMD at all sites; and no correlation was found between BMD and the joint-space narrowing score. According to stepwise logistic regression and after adjustment of BMD for age, women with an HOA combined score higher than 20 had signficantly higher BMD values at all skeletal sites. Sixty-nine women (23%) reported a history of osteoporotic fracture; among them, 20 (6.6%) reported a history of vertebral fracture. The OA score of both subgroups was significantly lower than that of women with no history of fracture. These data suggest that in elderly women the severity of HOA is positively correlated with bone mass and that women with a high score of HOA more rarely report a history of osteoporotic fracture. 相似文献

Impact of degenerative spinal diseases on bone mineral density of the lumbar spine in elderly women 总被引:2,自引:0,他引:2
Degenerative diseases of lumbar spine commonly noted in elderly people may affect their lumbar spine bone mineral density (BMD). The aim of this study is to determine whether the degree of degenerative spinal diseases is correlated with lumbar spine and femoral neck BMD. This study included 630 women age 60 years or over (mean age 73.3 ± 6.9 years) visiting the Osteoporosis Outpatient Clinic at the Tokyo Metropolitan Geriatric Medical Center. Subjects underwent anteroposterior and lateral X-rays of the lumbar spine. The score of degenerative spinal diseases for each subject was calculated according to the scores for the Kellgren-Lawrence method, osteophyte formation, bone sclerosis, disk space narrowing, and spondylolisthesis involving L1-L2 through L4-L5 interspaces. Moreover, the number of vertebral fractures at L2 through L4 was recorded. The BMD of the second to fourth lumbar spine from anteroposterior projections and femoral neck were measured using an Expert-5000 (GE Lunar, Madison, WI USA). Most subjects had degenerative diseases of the lumbar spine. Scores for the Kellgren-Lawrence method, osteophyte formation, bone sclerosis, disk space narrowing, and spondylolisthesis were positively correlated with lumbar spine BMD, while they were not correlated with femoral neck BMD. Multiple regression analysis indicated that the scores for osteophyte formation, bone sclerosis, and disk space narrowing were independently correlated with lumbar spine BMD. Thus, in this study, the scores for degenerative spinal diseases were correlated with lumbar spine BMD, while they were not correlated with femoral neck BMD. This discrepancy indicates that degenerative spinal diseases are associated with increased lumbar spine BMD measurements. Femoral neck BMD therefore may be more appropriate than lumbar spine BMD in evaluating osteoporosis in elderly women. 相似文献
