Risk Factors for Mortality in Critically Ill Patients with Coagulation Abnormalities:A Retrospective Cohort Study

Objective Coagulation abnormalities are common and prognostically significant in intensive care units(ICUs)and are associated with increased mortality.This study aimed to explore the association between the levels of coagulation markers and the risk of mortality among ICU patients with coagulation abnormalities.Methods This retrospective study investigated patients with coagulation abnormalities in the ICU between January 2021 and December 2022.The initial point for detecting hemostatic biomarkers due to clinical assessment of coagulation abnormalities was designated day 0.Patients were followed up for 28 days,and multivariate logistic regression analysis was utilized to identify risk factors for mortality.Results Of the 451 patients analyzed,115 died,and 336 were alive at the end of the 28-day period.Multivariate analysis revealed that elevated thrombin-antithrombin complex(TAT),tissue plasminogen activator inhibitor complex(tPAIC),prolonged prothrombin time,and thrombocytopenia were independent risk factors for mortality.For nonovert disseminated intravascular coagulation(DIC)patients,older age and thrombocytopenia were associated with increased risks of mortality,whereas elevated levels of plasminα2-plasmin inhibitor complex(PIC)were found to be independent predictors of survival.In patients with overt DIC,elevated levels of tPAIC were independently associated with increased risks of mortality.Nevertheless,thrombocytopenia was independently associated with increased risks of mortality in patients with pre-DIC.Conclusion Coagulation markers such as the TAT,tPAIC,PIC,and platelet count were significantly associated with mortality,underscoring the importance of maintaining a balance between coagulation and fibrinolysis.These findings highlight the potential for targeted therapeutic interventions based on specific coagulation markers to improve patient outcomes.

Clinical association between coagulation indicators and bone metastasis in patients with gastric cancer

BACKGROUND Bones are one of the most common target organs for cancer metastasis.Early evaluation of bone metastasis(BM)status is clinically significant.Cancer patients often experience a hypercoagulable state.AIM To evaluate the correlation between coagulation indicators and the burden of BM in gastric cancer(GC).METHODS We conducted a single-center retrospective study and enrolled 454 patients.Clinical information including routine blood examination and coagulation markers were collected before any treatment.Patients were grouped according to the status of BM.Receiver operating characteristic curves were used to assess diagnostic performance and determine the optimal cutoff values of the above indicators.Cutoff values,sensitivity and specificity were based on the maximum Youden index.Univariate and multivariate logistic regression analyses were used to evaluate the relationships between biomarkers and BM.RESULTS Of the 454 enrolled patients,191 patients were diagnosed with BM.The receiver operating characteristic curve analysis suggested that prothrombin time(PT)Wang X et al.Coagulation indicators predict bone metastasis WJGO https://www.wjgnet.com 1254 July 15,2023 Volume 15 Issue 7[cutoff:13.25;sensitivity:0.651;specificity:0.709;area under receiver operating characteristic curve(AUC)=0.738],activated partial thromboplastin time(aPTT)(cutoff:35.15;sensitivity:0.640;specificity:0.640;AUC=0.678)and fibrin degradation products(FDP)(cutoff:2.75;sensitivity:0.668;specificity:0.801;AUC=0.768)act as novel predictors for BM.Based on multivariate logistic regression analysis,the results showed the independent correlation between PT[odds ratio(OR):3.16;95%confidence interval(CI):1.612-6.194;P=0.001],aPTT(OR:2.234;95%CI:1.157-4.313;P=0.017)and FDP(OR:3.17;95%CI:1.637-6.139;P=0.001)and BM in patients with GC.Moreover,age,carcinoembryonic antigen,erythrocyte and globulin were found to be significantly associated with BM.CONCLUSION Coagulation markers,namely PT,aPTT and FDP,might be potential predictors for screening BM in patients with GC.
