摘要
目的探讨Graves病(GD)患者骨质疏松的患病情况,研究GD患者血清骨钙素、I型前胶原氨基端前肽(PINP)、血清碱性磷酸酶(ALP)、母-I型胶原羧基端肽(β-CTX)等骨转换指标的特征及其与甲状腺激素水平的相关性。方法入选明确诊断GD患者163例,电化学发光法测定甲状腺相关激素水平、骨钙素、PINP、CTX,全自动生化仪测定ALP、血钙、磷及尿钙/肌酐比值,用双能X线吸收骨密度仪(DEXA)测定腰椎正位,左侧股骨近端的骨密度。结果GD患者中,男性43例(26.4%),女性120例(73.6%),平均年龄(47±1)岁。其中骨质疏松37例(22.7%),非骨质疏松的126例(77.3%),按不同骨代谢状态分组比较,校正性别、年龄、体重指数后,骨质疏松组患者骨钙素、ALP、PINP、β-CTX和游离T1(FT3)水平高于非骨质疏松组(P〈0.05或P〈0.01)。校正性别、年龄、体重指数后,骨钙素、PINP、β—CTX水平与FT3水平呈正相关(均P〈0.01);根据FT3水平四分位数分组,各组骨钙素、PINP、β-CTX水平逐渐上升(P〈0.01)。结论Graves病甲状腺功能亢进患者具有较高的骨质疏松患病比例,高骨转换速率是GD合并骨质疏松患者的显著特征,高甲状腺激素水平是影响其骨转换速率和骨质疏松的重要因素。
Objective To evaluate osteoporosis and the bone turnover markers in patients with Graves' disease(GD) and the association of bone turnover markers including serum osteocalcin (OCN) , I procollagen N- terminal propeptide(PINP), serum alkaline phosphatase(ALP), and β-I collagen carboxyl-terminal peptide( β- CTX)with thyroid hormone levels. Methods A total of 163 patients with Graves' disease were enrolled. Serum thyroid hormone, OCN, PINP, and β-CTX levels were measured by the method of ethehemiluminescence. Serum ALP, calcium, phosphorus, and urinary calcium/creatinine ratio were measured by automatic biochemical system. Bone mineral density (BMD) of lumbar spines 1-4 ( L 1-4) and the proximal left femur was detected by dual energy x- ray absorptiometry. Results GD cases enrolled were composed of 43 men(26.4% ) and 120 women(73.6% ), with an average age of (47 ± 1 ) years. There were 126 cases (77.3%) with normal BMD, and 37 cases ( 22. 7% ) with osteoporosis. OCN, ALP, PINP, β-CTX, and free T3 levels were significantly higher in the group of osteoporosis than those in the group with normal BMD ( P〈0. 05 or P〈0. 01 ) after adjusting for sex, age, and BMI. The levels of OCN, PINP, and β-CTX were positively correlated with serum FT3 level ( all P〈0. 01 ) and were also progressively increased according to the quartile groups of FT3 levels ( P〈0. 01 ) after sex, age, and BMI were adjusted. Conelusion Patients with Graves' disease had a high incidence of osteoporosis with characristic high rate of bone turnover, which is related to the raised thyroid hormone levels.
