甲状腺功能异常患者骨代谢变化的探讨

为探讨甲状腺功能改变对骨代谢的影响 ,对 91例甲亢 ,37例甲减及 5 1名健康对照者用免疫放射 (IR MA)法测骨钙素 (BGP)及甲状旁腺素 (PTH) ,用镅 - 2 41单光子跟骨密度仪测骨密度 (BMD)。结果发现 ,BGP含量 :甲亢组明显高于对照组 (P <0 .0 0 1) ,甲减组明显低于对照组 (P <0 .0 0 1) ;PTH含量 :甲亢组低于对照组 (P <0 .0 5 ) ,甲减组明显高于对照组 (P <0 .0 0 1) ;骨密度测定 :甲亢与甲减组骨质疏松发病率均明显高于对照组 (P <0 .0 0 1)。甲亢与甲减组骨质疏松发病年龄前移 ,甲减组 5 5岁以上都有骨质疏松。BGP和PTH改变明显早于骨密度变化 ,可作为甲状腺功能异常时骨代谢变化的灵敏指标 ,特别用于疗效观察

The Exploration of the Changes in Bone Metabolism in Patients with Abnormal Thyroid Function

To explore the changes in bone metabolism with abnormal thyroid function, BGP and PTH in 91 patients with hyperthyroidism, 37 patients with hypothyroidism, 51 controls, were measured by means of IRMA, calcaneus heel bone density (BMD) was measured by means of 241 Am single photon absorptiometry. BGP levels in hyperthyroidism were significantly higher than those in controls ( P <0.001). BGP levels in hypothyroidism were significantly lower than those in controls( P <0.001).PTH levels in hyperthyroidism were a little lower than those in controls ( P <0.05).PTH levels in hypothyroidism were significantly higher than those in controls( P <0.001). The measurement of BMD showed that the prevalence rates of osteoporosis (OP) in hyperthyroidism and hypothyroidism were significantly higher than those in controls. In hyperthyroidism and hypothyroidism groups the age of OP tends to be younger. The patients with hyperthyroidism over 55 years of age were all suffered from OP. The changes in BGP and PTH were earlier than BMD, so BGP and PTH can be used as sensitive indicator of the changes in bone metabolism with abnormal thyroid function, especially for curative effect observations.
