摘要(Abstract):
[目的]通过对脊柱结核(STB)患者骨代谢标志物尿脱氧吡啶啉(DPD)的测定,观察其变化与脊柱结核病的关系;评价其在判定继发于肺结核(PTB)的脊柱结核筛选诊断方面的临床意义。[方法]采用自动化学发光免疫分析法及自动化学分析法检测脊柱结核组、肺结核组和健康对照组的尿DPD水平,其中尿DPD以尿肌酐(Cr.)来校正(DPD/Cr.),将检测结果进行诊断有效性分析。[结果]脊柱结核患者、肺结核患者、健康对照组DPD的测定值分别为(14.9±9.8)μmol/molCr.、(6.4±2.6)μmol/molCr.和(6.3±2.0)μmol/molCr.,脊柱结核患者尿DPD较肺结核患者、健康成人对照组显著增高,差异具有显著性意义(P=0.001,P=0.000)。肺结核患者与健康对照组相比,尿DPD的检测差异均无显著性意义(P=0.751)。所检测的脊柱结核患者尿DPD的接受者工作特性曲线(ROC)下面积为0.83,在ROC曲线下,DPD测定值以8.4μmol/molCr.为截断点时,诊断脊柱结核的敏感性是87%,特异性是73%。[结论]脊柱结核可以引起骨代谢的改变,尿DPD能敏感地反映脊柱结核骨吸收的状况,尿液DPD检测有助于继发于肺结核的脊柱结核患者的早期筛选。
