摘要:

目的 探讨甲状旁腺激素(PTH)、C反应蛋白(CRP)、骨保护素(OPG)/吡啶啉(PYR)比值在老年骨质疏松症(OP)中的临床意义。方法 选取疑似OP患者137例,根据是否确诊OP分为OP组(32例)和非OP组(105例),收集所有患者的临床资料,同时检测腰椎、股骨颈骨密度(BMD)和血清PTH、CRP、OPG水平,以及尿PYR水平,计算OPG/PYR比值。采用Pearson相关分析和偏相关性分析评估各项指标与腰椎、股骨颈BMD的相关性。采用受试者工作特征(ROC)曲线评估各项指标诊断OP的效能。结果 OP组糖尿病比例和血清PTH、CRP水平高于非OP组(P<0.05),腰椎BMD、股骨颈BMD、OPG/PYR比值均低于非OP组(P<0.05)。2个组之间年龄、性别、体质量指数、饮酒史比例、吸烟史比例、高脂血症比例、冠心病比例、高血压比例差异均无统计学意义(P>0.05)。Pearson相关分析结果显示,PTH、CRP与腰椎BMD、股骨颈BMD均呈负相关(P<0.05),OPG/PYR比值与腰椎BMD、股骨颈BMD均呈正相关(P<0.05)。偏相关性分析结果显示,控制糖尿病因素后,PTH、CRP、OPG/PYR比值仍与腰椎BMD和股骨颈BMD有关(P<0.05)。ROC曲线分析结果显示,PTH、CRP、OPG/PYR比值单项检测和联合检测诊断OP的曲线下面积(AUC)分别为0.856、0.826、0.861、0.912。结论 PTH、CRP、OPG/PYR比值与OP有关,或可用于OP的辅助诊断及病情监测。

Abstract:

Objective To investigate the roles of parathyroid hormone(PTH),C-reactive protein(CRP),osteoprotegerin(OPG)/pyridinoline(PYR) ratio in elderly patients with osteoporosis(OP). Methods Totally,137 patients with suspected OP were enrolled and classified into OP group(32 cases) and non-OP group(105 cases) according to the presence or absence of OP. The clinical data were collected,and lumbar spine and femoral neck bone mineral densities(BMD),serum PTH,CRP and OPG levels and urinary PYR levels were determined. OPG/PYR ratio was calculated. Pearson correlation analysis and partial correlation analysis were used to analyze the relationship between each index and lumbar spine and femoral neck BMD. Receiver operating characteristic(ROC) curve was used to analyze the efficiency of OP. Results The proportion of diabetes mellitus and serum PTH and CRP levels were higher in OP group than those in non-OP group(P<0.05),and lumbar spine BMD,femoral neck BMD and OPG/PYR ratio were lower than those in non-OP group(P<0.05). Between the 2 groups,age,sex,body mass index,the proportion of alcohol consumption history,the proportion of smoking history,the proportion of hyperlipoidemia,the proportion of coronary heart disease and the proportion of hypertension had no statistical significance(P>0.05). Pearson correlation analysis showed that PTH and CRP were negatively correlated with lumbar spine BMD and femoral neck BMD(P<0.05),and the OPG/PYR ratio was positively correlated with lumbar spine BMD and femoral neck BMD(P<0.05). The results of partial correlation analysis showed that PTH,CRP and OPG/PYR ratio were correlated with lumbar spine BMD and femoral neck BMD after controlling for the factor of diabetes mellitus(P<0.05). The results of ROC curve analysis showed that the areas under curves(AUC) of PTH,CRP and OPG/PYR ratio single and combined determinations to diagnose OP were 0.856,0.826,0.861 and 0.912,respectively. Conclusions PTH,CRP,OPG/PYR ratio are correlated to OP,which can be used in the auxiliary diagnosis and disease monitoring of OP.
