    AbstractBackground: The dysregulated host responses play a crucial role in the pathophysiology process of sepsis-induced disseminated intravascular coagulation (DIC). The study aimed to characterize the dynamic alternation of immune-related biomarkers and their relationship with the progression of DIC during sepsis. Methods: A prospective, observational study was conducted in a tertiary care academic hospital. Six hundred forty patients with sepsis were classified into three groups according to the International Society on Thrombosis and Hemostasis (ISTH) score: 383 involved patients without DIC (ISTH = 0), 168 sepsis with nonovert DIC (ISTH = 1-4), and 89 sepsis with overt DIC (ISTH ≥5). Eighteen immune-related biomarkers and six routine coagulation variables were examined at D1, D3, and D7 upon enrollment. The association between the immune parameters and the DIC deterioration was assessed during sepsis. Results: The study showed a 40% coagulation disorder and a 14% incidence of overt DIC in patients with sepsis. The patients with overt DIC displayed pronounced immune disorders from D1 to D7 upon sepsis, which was characterized by the decreased percentage of monocyte HLA-DR (mHLA-DR), increased percentage of regulatory T cells, the levels of procalcitonin, neutrophil CD64 index, and systemic inflammatory cytokines relative to nonovert DIC or non-DIC patients. In multivariate analysis, the combination of anti-inflammatory cytokine IL-10 and mHLA-DR at D1 upon enrollment had a superior predictive value for predicting DIC deterioration in sepsis (area under the curve = 0.87, P < 0.0001). Conclusion: These data illustrate that immunosuppression can crosstalk with coagulation disorder during sepsis and present an additional evaluation tool to predict DIC deterioration.Copyright © 2024 by the Shock Society.
