摘要
目的检测脓毒症及合并弥漫性血管内凝血(DIC)患者血清金属蛋白酶组织抑制剂(tissue inhibitor of metalloproteinase, TIMP)水平,并判断其对脓毒症患者发展成为DIC的预测诊断价值。方法取60名患者,其中严重脓毒症患者28例(SS组),脓毒症合并DIC患者12例(SSD组),同期门诊体检者20例为对照组,收集临床及实验室参数,计算APACHEⅡ评分和DIC评分,采用酶联免疫吸附(ELISA)方法检测血清TIMP-1和TIMP-2的水平。结果SS组患者血清TIMP-1水平(723.74±96.27)较对照组(574.24±79.99)明显升高(P〈0.05),TIMP-2水平(68.08±14.87)较对照组(89.99±18.45)明显降低(P〈0.05)。SSD组患者血清TIMP-1水平(907.56±200.20)则较SS组升高明显(P〈0.05),而TIMP-2水平(44.84±22.13)也较ss组降低更明显(P〈0.05)。相关分析显示TIMP-1主要与纤维蛋白原(FIB)呈负相关,差异具有统计学意义(P〈0.05),而与D-二聚体呈正相关,差异具有统计学意义(P〈0.05);血清TIMP-2则与血小板计数(PⅡ)、降钙素原(PCT)、DIC评分呈负相关,差异具有统计学意义(P〈0.05)。ROC曲线图显示TIMP-1/TIMP-2的AUC=0.896,95%CI:0.843-0.950(P〈0.05),较TIMP-1或TIMP-2的AUC更高。结论脓毒症合并DIC患者的血清TIMP-1水平明显升高,主要影响纤溶系统;TIMP-2水平明显下降,主要影响血小板功能;TIMP-1/TIMP-2对脓毒症合并DIC的发生具有诊断价值。
Objective To examine the levels of serum tissue inhibitor of metalloproteinase in severe sepsis patients with disseminated intra-vascular coagulation (DIC) and evaluate its diagnostic value in severe sepsis with DIC. Methods Sixty patients were divided into 3 groups, namely severe sepsis group (SS group, n = 28), severe sepsis with DIC group ( SSD group, n = 12) and normal group ( n = 20). Clinical data ineluding APACHE Ⅱ score and DIC score of these patients were collected. Serum levels of TIMP-1 and TIMP-2 of these patients were measured by using ELISA. Results The patients of SS group had higher levels of TIMP-1 (723.74 ± 96. 27 ) and lower levels of TIMP-2 (68.08 ± 14. 87 ) than healthy control subjects (TIMP-1 : 574. 24± 79.99, TIMP-2 : 89.99 ± 18.45) (P 〈 0. 05). The patients of SSD group had higher levels of TIMP-1 (907. 56 ± 200. 20) and lower levels of TIMP-2 (44. 84 ± 22. 13 ) than patients of SS group (P 〈 0. 05 ). An association was found between TIMP-1 and fibrinogen (FIB) (r = - 0. 392, P 〈 0.05), TIMP-1 and D-dimer ( r = 0. 407, P 〈 0. 05 ), TIMP-2 and PLT ( r = 0. 484, P 〈0. 01 ), TIMP-2 and PCT (r = - 0. 523, P 〈 0.01 ), TIMP-2 and DIC score ( r = - 0. 579, P 〈 0. 01 ). The areas under the curves (AUC) for TIMP-1/TIMP-2 was 0. 896 (95% CI: 0. 843 - 0. 950 ( P 〈 0. 05 ). Conclusions Serum levels of TIMP-1 in patients with severe sepsis complicated with DIC increased and TIMP-2 decreased, suggesting they were valuable in diagnosis of severe sepsis complicated with DIC.
