摘要
目的对败血症患者凝血、抗凝血、纤溶、内皮系统的功能变化进行研究,并评估各项指标水平变化与预后的关系。方法采用 Sysmex CA-7000型血液凝固仪测定85例败血症患者的蛋白 C 活性(PC:A)、抗凝血酶活性(AT:A)、凝血因子 FⅤ活性(FV:A)、凝血因子 FⅦ活性(FⅦ:A)、凝血因子 FⅧ活性(FⅧ:A)、凝血因子 FⅨ活性(FⅨ:A)、vW 因子(von Willebrand Factor,vWF)、纤维蛋白原(FIB)、组织型纤溶酶原激活物(t-PA)、纤溶酶原激活物抑制物-1(PAI-1)、D-二聚体(D-Dimer),凝血酶原时间国际标准化比值(PT INR)、活化部分凝血活酶时间(APTT)、凝血酶时间(TT),同时测定50名健康人作为对照组。结果败血症患者组 FIB、PAI-1、vWF 及 D-Dimer 分别为(3 720±2 290)mg/L、(2.4±1.0)Au/ml、(167.5±31.2)%及(355±128)μg/L,高于对照组的(2 950±870)mg/L、(0.6±0.5)Au/ml、(94.1±32.5)%及(169±94)μg/L,差异有统计学意义(P<0.01);FV:A、FⅦ:A、FⅧ:A、FⅨ:A、PT INR、APTT 及 TT 分别为(98±37)%、(95±33)%、(96±43)%、(99±40)%、(1.23±0.35)、(33±12)s 及(21±7)s,与对照组的(97±18)%、(99±18)%、(103±22)%、(102±25)%、(1.15±0.32)%、(31±7)%及(19±4)s 比较,差异无统计学意义(P>0.05);AT:A、PC:A、t-PA 水平分别为(76±17)%、(65±19)%及(0.22±0.09)U/ml,低于对照组的(107±9)%、(101±14)%及(0.45±0.13)U/ml,差异有统计学意义(P<0.01)。不同预后患者抗生素治疗第3~5天,痊愈患者组 AT:A、PC:A、t-PA 分别为(94±9)%、(90±11)%及(0.37±0.15)U/ml,高于死亡患者组的(58±23)%、(55±17)%及(0.16±0.09)U/ml,差异有统计学意义(P<0.01);vWF、D-dimer 及 PAI-1分别为(117.2±20.5)%、(192±62)μg/L 及(0.8±0.3)Au/ml,低于死亡患者组的(198.1±44.6)%、(697±213)μg/L 及(2.9±1.2)Au/ml,差异有统计学意义(P<0.01)。结论败血症患者的抗凝血、纤溶系统功能发生显著变化,血栓形成风险增加,测定上述指标对了解败血症病程发展趋势具有辅助作用。
Objective Study on the change of function in coagulation system, anticoagulation system, fibrinolytic system, endothelium system in septicemia patients, and to evaluate the relationship between the change of the parameters and the thrombosis prognosis. Methods The protein C( PC: A), antithromhin(AT:A), factor V activity(FⅤ: A), factor Ⅶ activity(FⅦ: A), factor Ⅷ activity(FⅧ: A), factor Ⅸ activity( FⅨ: A), yon Willebrand factor(vWF), fibrinogen(FIB), plasminogen activator inhibiter- 1( PAI-1 ), D-Dimer, prothrombin time international normalized ratio (PT INR ), activated partial thromboplasfin time (APTr), and thrombin time (TT) were assayed by the Sysmex CA-7000 blood coagulation instrument in 85 septicemia patients and control group. Results Compared the patients group with the control[ FIB(2 950 ± 870) mg/L, PAI-I(0.6 ±0.5) Au/ml, vWF(94. 1 ±32.5)%, D-dimer (169 ±94) μg/L, FV: A(97 ± 18)%, FⅦ: A(99 ± 18) %, FⅧ: A( 103 ±22)%, FⅨ: A( 102 ±25) %, PT INR 1.15 ±0. 32, APTT (31 ±7) s, TT(19 ±4) s, AT: A(107 ±9) %, PC: A(101 ± 14) %, t-PA (0. 45 ±0. 13) U/m1], the level of the FIB[ (3 720 ±2 290) mg/L], PAI-1 [ (2. 4 ± 1.0) Au/ml], vWF [ ( 167.5 ± 31.2 ) % ], D-Dimer[ ( 355 ± 128 ) μg/L] were increased obviously( P 〈 0. 01 ), and the level of the FV:A[ (98 ±37)% ], FⅦ: A[ (95 ±33)% ], FⅧ: A[ (96 ±43)% ], FIX: A[ (99 ±40)% ], PT INR(1.23±0. 35), APTT[ (33 ±12)s], TT[ (21±7)s]had no change significantly(P 〉0. 05), the level of the AT: A[ (76±17)% ], PC: A[ (65 ±19)% ] ,t-PA[ (0.22 ±0. 09) U/ml]were decreased obviously in patients group ( P 〈 0. 01 ). Compared the recovery patients group [ AT: A ( 94 ± 9 ) %, PC: A ( 90 ±11)%, t-PA(0. 37 ±0. 15)U/nd, vWF(117. 2 ±20. 5)%, D-Dimer(192 ±62) μg/L, PAI-1 (0. 8 ±0. 3) Au/nd] with the death patients group, the level of the AT: A[ (58±23)% ], PC: A[ (55 ±17) % ], t-PA [ (0. 16 ±0. 09) U/roll were decreased obviously(P 〈0. 01 ) and the vWF[ ( 198. 1 ±44. 6)% ], D-Dimer [(697±213) μg/L], PAI-1 [(2.9 ± 1.2) Au/ml] were increased obviously(P 〈0.01) in the death patients group between the 3-5 day after the antibiotics treatment. Conclusions The function in antico agulation system and fibrinolytic system were significantly changed and the risk of thrombogenesis increased in septicemia patients, so it could help the clinical doctors to investigate the development of the course of diseases through assaying the above parameters.
