Clinical correlation between coagulation disorders and sepsis in patients with liver failure.

OBJECTIVE: This study aimed to explore the clinical detection and prognosis of coagulation function in patients with liver failure and sepsis. METHODS: The plasma fibrinogen (FIB), factor II, factor VII, factor V, factor IV, antithrombin III (ATIII), platelet (PLT), mean PLT volume (MPV), D-dimer, prothrombin activity (PTA), and fibrin degradation product (FDP) levels and thromboelastogram values were detected in patients with liver failure complicated with sepsis and compared with those in the liver failure and liver cirrhosis groups. The patients with liver failure complicated with sepsis were analyzed by univariate and multivariate logistic regression, and the regression equation was established. RESULTS: The levels of FIB, factor II, factor VII, factor V, ATIII, PLT, MPV, D-dimer, and FDP in the patients with liver failure complicated with sepsis were compared with those in the control group patients, and the differences were statistically significant (p < 0.05). Among the thromboelastography parameters in the patients with liver failure and sepsis, the differences in the K-value, R-value, angle, maximum amplitude, and coagulation index values compared with those of the control group were statistically significant (p < 0.05). The logistic regression model obtained was as follows: p = 1/(1 + e [-0.128×X1-0.058×X2 + 0.211×X3 + 0.2×X4 + 0.25]). The specificity, sensitivity, and accuracy values of the regression equation in determining the prognosis were 92%, 93.9%, and 92.8%, respectively. Among the 11 factors, factor VII, PLT, FDP, and D-dimer were included in the regression equation. CONCLUSION: Coagulation disorder is exacerbated in patients with liver failure and sepsis. Among the 11 coagulation-related factors, factor VII, PLT, FDP, and D-dimer may be the independent factors influencing the prognosis of patients with acute liver failure and sepsis.

Study of the Expression of Inflammatory Factors IL-4, IL-6, IL-10, and IL-17 in Liver Failure Complicated by Coagulation Dysfunction and Sepsis.

OBJECTIVE: The present study aims to investigate the cytokines interleukin (IL)-4, IL-6, IL-10, and IL-17 in the peripheral blood of patients with acute-on-chronic liver failure combined with sepsis, patients with acute-on-chronic liver failure, and patients with liver cirrhosis; to investigate the changes in the levels of inflammatory factors in cases of coagulation dysfunction in liver failure combined with sepsis; and to discover more typical inflammatory factors for further evaluation by functional experiments. METHODS: In the present study, 41 patients with acute-on-chronic liver failure and sepsis were enrolled as study subjects. These patients were compared with 20 patients with either acute-on-chronic liver failure and liver cirrhosis during the same period. The changes in IL-4, IL-6, IL-10, and IL-17 were detected in each group by enzyme-linked immunosorbent assay, and SPSS 17.0 software was adopted for data analysis. RESULTS: There were no significant changes in the levels of IL-4 in any of the groups. However, the levels of IL-6, IL-10, and IL-17 were significantly higher in the acute-on-chronic liver failure and sepsis group than in the acute-on-chronic liver failure and the liver cirrhosis groups. CONCLUSION: The present study shows that when liver failure is accompanied by sepsis, the serum levels of inflammatory factors IL-6, IL-10, and IL-17 are significantly increased. This could be closely correlated with the occurrence and development of coagulation dysfunction and sepsis. These findings provide new ideas for delaying the deterioration of patients with liver failure in clinical practice.
