Objective: To clarify the role of coagulation and fibrinolysis as well as the level of neutrophil extracellular traps (NETs) in patients with sepsis, and to explore their clinical significance in identifying the disease and predicting the prognosis.
Methods: In this retrospective study, the clinical data from 120 patients with sepsis admitted to People's Hospital of Changshou from January 2019 to December 2021 were analyzed. The patients were divided into a survival group and a death group according to the survival of patients within 28 days of admission. Another 120 patients with common bacterial infection were selected as the bacterial group and 120 healthy subjects who underwent physical examination in our hospital during the same period were selected as the healthy group. NETs, coagulation and fibrinolysis indexes, prothrombin time (PT), fibrinogen (FIB), D-dimer level, International Normalized Ratio (INR), Acute Physiology and Chronic Health Evaluation (APACHE) II score, and sequential organ failure assessment (SOFA) score of the patients with sepsis were compared with those of bacterial group and healthy group. Correlations between these measures were analyzed, and the predictive value of NETs for survival in patients with sepsis was assessed.
Results: Compared with bacterial group and healthy group, the levels of serum NETs, PT, FIB, D-dimer, and INR value in sepsis patients were significantly increased. The level of NETs was positively associated with APACHE II score, SOFA score, PT, FIB, D-dimer, and INR. INR showed good performance in predicting death within 28 days after admission in sepsis patients.
Conclusion: The NETs and coagulation indexes have high predictive value for the prognosis of patients with sepsis.
