Purpose: The aim of this study was to investigate the relationship between ARF and coagulopathy in patients with sepsis and to explore the prognostic value of these conditions.
Patients and Methods: The data of 271 patients with sepsis-associated coagulopathy admitted from June 2021 to June 2022 were reviewed. The patients were divided into a survival group and a nonsurviving group according to patient prognosis. Independent sample t tests were utilized to compare laboratory parameters within 24 hours of admission, as well as the APACHE II and SOFA scores, between the two patient groups. According to the sepsis-associated coagulation dysfunction (SAC) grading criteria for grading, Spearman correlation analysis was used to study the relationship between blood creatinine and SAC grading and assignment scores, and receiver operating characteristic (ROC) curves and Cox’s proportional risk regression model were used to explore the factors affecting the prognosis of SAC patients.
Results: Spearman correlation analysis revealed strong associations between serum creatinine (Scr) concentration, SAC classification, and SAC score, with coefficients above 0.7. SAC classification outcomes varied significantly with severity: mild severity had a 77.6% survival rate versus 22.4% mortality; moderate severity had 21.5% survival versus 78.5% mortality; and severe cases had a 0.7% survival rate versus 99.3% mortality (P< 0.01 for all). Multivariate analysis revealed significant predictors of outcome, including multiple organ dysfunction syndrome (MODS), with an OR of 2.070 (P=0.019); the SOFA score (OR=1.200, P< 0.01); the international normalized ratio (INR) (OR=0.72, P=0.013); and the Scr level (OR=0.995, P< 0.01). The areas under the ROC curves for the SOFA score, APACHE II score, and SAC classification were > 0.8, all P < 0.05.
Conclusion: In patients with sepsis, SAC grade 3 or a SAC score of 4 or higher is associated with poorer prognosis, and the interaction of acute kidney injury exacerbates the degree of SAC, consequently affecting prognosis.
Plain Language Summary: To investigate the relationship between acute renal dysfunction and coagulation dysfunction in patients with sepsis and to explore the prognostic value of these conditions. We collected information and laboratory indicators from 271 patients, classified these two groups of patients according to the grading criteria for sepsis-associated coagulation dysfunction (SAC), and compared the differences between them. We utilized Spearman correlation analysis to investigate the relationship between blood creatinine and the severity of sepsis-associated coagulation dysfunction (SAC). Additionally, we employed a Cox proportional hazards regression model to study the factors influencing the prognosis of SAC patients. This study revealed a significant positive correlation between blood creatinine levels and SAC grade. Furthermore, the presence of MODS, INR, blood creatinine, and SOFA score can serve as independent predictive factors for mortality. We can infer that there is a significant correlation between coagulation function parameters and blood creatinine levels, which play a crucial role in the diagnosis and prognostic analysis of sepsis. In patients with sepsis, a higher grade of SAC or an SAC score of 4 or higher indicates a poorer prognosis. Additionally, the interaction with acute kidney injury exacerbates the severity of SAC, thereby impacting patient prognosis.
