RESUMEN

【Objective】 To investigate the relationship between the level of thrombin-antithrombin complex (TAT)/α2-plasmin inhibitor-plasmin complex (PIC) and the utilization rate of mechanical ventilation (MV) in critically ill patients. 【Methods】 For the cross-sectional study, adult patients who had been admitted to the intensive care unit (ICU) for one day or longer and had a record of the first four tests for thrombosis were enrolled. Age, gender, the results of TAT and PIC, disseminated intravascular coagulation score, treatment, and diagnostic information were retrospectively collected from the hospital information system and laboratory information system. Logistic regression model was used to explore the relationship between TAT/PIC and the MV utilization rate. Interaction analysis and subgroup analysis were conducted to explore whether there was any difference between patients with different age and gender, patients with/without DIC, and with/without infection. 【Results】 A total of 1 176 patients were enrolled in this study. The median of the first TAT/PIC was 15.84 (8.13-33.11) in all the patients. The multivariable Logistic regression model results showed that for every 5 increase in TAT/PIC, the possibility of using MV increased by 2.9% (OR=1.029, 95% CI: 1.008-1.050), and the possibility of using MV in Q3 patients was 1.566 times than that in Q1 patients (OR=1.566, 95% CI: 1.095-2.239); the possibility of using MV in Q4 patients was 2.457 times than that in Q1 patients (OR=2.457, 95% CI: 1.694-3.563). Interaction results showed that the relationship between the level of TAT/PIC and MV usage was different in patients with and without infection (Pinteraction=0.02). Further subgroup analysis showed that in the infected patients (674 cases), the possibility of using MV increased by 5.9% for every 5 increase in TAT/PIC (OR=1.059, 95% CI: 1.022-1.097, P=0.001), while there was no significant difference between different TAT/PIC and MV usage in non-infected patients (502 cases) (OR=1.012, 95% CI: 0.984-1.040, P=0.405). 【Conclusion】 There is a correlation between the level of TAT/PIC and mechanical ventilation in patients with infection in the ICU.

RESUMEN

Objective To investigate the detection and clinical significance of thrombus molecular markers in diffuse large B-cell lymphoma (DLBCL). Methods We collected the blood specimens of 60 patients with DLBCL, involving 23 cases in the initial treatment group, 24 cases in the remission group and 13 cases in the non-remission group, 23 cases in the thrombus group and 37 cases in the non-thrombus group. We selected 46 healthy people in the same period as the control group. The levels of thrombomodulin (TM), plasmin-α2 plasmin inhibitor complex (PIC), tissue plasminogen activator-plasminogen activator inhibitor-1 complex (t-PAIC) and thrombin-antithrombin Ⅲ complex (TAT) in plasma were detected by chemical immunoassay, and the levels of lactate dehydrogenase (LDH) in serum was detected by automatic biochemical analyzer. We analyzed the differences of thrombus molecular markers among groups and prognostic factors. Results The levels of TM and PIC in plasma of lymphoma patients were higher than those in health control group (P < 0.05). The levels of TM and PIC in the initial treatment and non-remission groups were significantly higher than those in the remission group (P < 0.05). The levels of TM, PIC and TAT in thrombus group were higher than those in non-thrombus group (P < 0.05). TM and PIC levels in plasma were closely related to the prognosis of DLBCL patients. PIC was an independent prognostic factor (P < 0.001). TM and PIC levels were correlated with LDH prognostic indicators in lymphoma patients. Conclusion TM and PIC levels in plasma are significantly increased in DLBCL patients. They are expected to be the indicators for effectiveness and prognosis of DLBCL patients.
