摘要:

背景:骨质疏松症并非一个简单的骨定量的问题。骨质疏松症的评估是年龄、性别、骨代谢、骨形成和骨生物力学动态结果。抗酒石酸酸性磷酸酶5b和骨碱性磷酸酶分别反映的是骨吸收和骨形成的两个重要指标。

 

目的:分析骨代谢标志物在老年骨质疏松症诊疗中的临床意义以及其与骨密度的相关性。

 

方法:选取老年骨质疏松症患者100例,年龄分布:65-70岁30例、71-75岁40例、76-80岁30例;排除合并糖尿病、肿瘤及其他影响骨质状况疾病。所有患者入院后检测骨生化4项,包括:抗酒石酸酸性磷酸酶5b、骨碱性磷酸酶、骨钙素N端中分子片段以及25-羟维生素D。据检测结果患者分成抗酒石酸酸性磷酸酶5b升高组和骨碱性磷酸酶升高组,分别行抗骨质疏松症治疗3个月。分析患者骨密度和骨生化4项检查结果与性别、年龄的相关性;进行两组治疗前后骨生化4项差异性比较及组间差异性比较。

 

结果与结论:腰椎和髋关节骨密度随年龄增加而降低(P < 0.05);男性组的腰椎和股骨颈Word三角区骨密度测量值较女性组高。抗酒石酸酸性磷酸酶 5b、骨碱性磷酸酶、骨钙素N端中分子片段随年龄增加在人体内含量升高(P < 0.05),而25-羟维生素D随年龄增加在人体内含量降低(P < 0.05);女性骨质疏松症患者抗酒石酸酸性磷酸酶 5b、骨碱性磷酸酶、骨钙素N端中分子片段在人体内含量较男性患者高,而25-羟维生素D在人体内含量较男性患者低。两组患者使用抗骨质疏松症药物治疗后骨生化4项指标均较治疗前有改善。结果提示,骨代谢标志物检测能明确患者体内是以成骨细胞功能为主和还是以破骨细胞功能为主,以便指导临床针对性使用抗骨质疏松症药物,为临床治疗骨质疏松症和监测疗效提供科学依据。

Abstract:

BACKGROUND: Osteoporosis is not a simple quantitative bone problem. Assessment of osteoporosis is related to age, gender, bone metabolism, bone formation and bone biomechanical dynamics. Tartrate-resistant acid phosphatase 5b (TRACP 5b) and bone alkaline phosphatase (BAP) are two important indicators reflecting bone resorption and bone formation, respectively.

OBJECTIVE: To investigate the clinical significance of bone metabolic markers in the diagnosis and treatment of senile osteoporosis, and to explore its correlation with bone mineral density changes.
METHODS: Totally 100 elderly patients with osteoporosis were enrolled, including 30 cases of 65-70 years old, 40 cases of 71-75 years old, and 30 cases of 76-80 years old. Patients with diabetes, cancers and other bone disorders were excluded. At admission, all patients were measured four bone biochemical markers, including TRACP 5b, BAP, N-terminal midfragment osteocalcin and 25-hydroxyvitamin D. According to the test values of TRACP 5b and BAP, patients were divided into TRACP 5b upregulation group and BAP upregulation group. The correlation of bone mineral density and four biochemical markers with sex and age was analyzed, and intergroup and intragroup differences in four biochemical markers were compared.
RESULTS AND CONCLUSION: The bone mineral densities of the lumbar vertebra and hip were decreased with age  (P < 0.05); the bone mineral densities of the lumbar spine and Ward’s triangle in the male patients were higher than those in the female patients. The values of TRACP 5b, BAP, N-terminal midfragment osteocalcin were increased with age (P < 0.05), while the level of 25-hydroxyvitamin D was decreased with age (P < 0.05). Compared with the male patients, the levels of TRACP 5b, BAP and N-terminal midfragment osteocalcin were higher in the female patients, but the level of 25-hydroxyvitamin D was lower in the female patients. After anti-osteoporosis treatment, these four biochemical markers were all improved in the two groups. These findings indicate that the detection of bone metabolic markers contributes to explain whether the main function of osteoblasts or osteoclasts is present in the body, thereby guiding the clinical use of targeted anti-osteoporosis drugs and providing a scientific basis for the clinical treatment and monitoring of osteoporosis.
