Introduction: Covid-19 is an infectious disease caused by the severe acute respiratory syndrom coronavirus 2 and causes a series of respiratory symptoms. Considering the appearance and development of symptoms, the course of Covid-19 can go from mild to severe. Depending on the course of Covid-19, the laboratory parameters change a lot, trying to defend the organism against the foreign pathogen and all the changes it causes. Therefore, the aim of this study is to observe the differences between biochemical, hematological and coagulation parameters depending on the disease stage of Covid-19 patients. Material and methods: We conducted cross-sectional study which included 160 Covid-19 patients from Sarajevo, Bosnia and Herzegovina. Biochemical, hematological and coagulation analyzes were performed. Results: Covid-19 patients with a severe clinical course have higher average values of fibrinogen (6.53 ± 4.47, p < 0.001), D-dimer (6.89 ± 7.81, p < 0.001), APTT (32.05 ± 5.96, p = 0....
Coagulation factors as potential predictors of COVID-19 patient outcomes
Medical Journal of Indonesia
BACKGROUND Causes of death and length of hospitalization in patients with COVID-19 have been associated with coagulopathy. The coagulopathy mechanism involves the process of coagulation and endothelial damage triggered by an inflammatory response of the SARS-CoV-2 infection due to excessive release of proinflammatory cytokines. This study aimed to determine the association of coagulation factors as potential predictors of COVID-19 patient outcomes. METHODS This retrospective study was performed on 595 patients at Wahidin Sudirohusodo Hospital, Makassar, from June 2020 to June 2021. Participants were recruited using total sampling and assessed for COVID-19 severity using the World Health Organization classification and coagulation factors (D-dimer, fibrinogen, thrombocyte, and prothrombin time [PT]). Patient outcome assessments were survival and length of hospitalization. RESULTS We found a significant sex-based disparity, with a higher COVID-19 incidence in males. Severe cases were ...

Can disseminated intravascular coagulation scores predict mortality in COVID-19 patients?
2021
Objectives Complications related to coronavirus disease 2019 (COVID-19) may lead to disseminated intravascular coagulation (DIC), which has been reported to be among the known causes of mortality in such patients. This study aims to analyse the incidence of DIC in COVID-19 non-survivors and to assess the association between DIC and its comorbidities. Methods The medical records of 154 non-survivors of COVID-19, hospitalised between April 2020 and July 2020, were retrospectively analysed. The International Society on Thrombosis and Haemostasis (ISTH) criteria for DIC were applied to identify the occurrence of coagulopathy. The receiver-operating characteristic (ROC) analysis was used to assess the association between DIC and its comorbidities. Results Out of 154 non-survivors, non-overt DIC was observed in 94.8% of the patients, whereas only 5.2% fulfilled the overt criteria of DIC with a mean age 64.6 years. The mortality rate was 4.5 times higher among men than women. The D-dimer l...

Background: Patients infected by coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), display various symptoms and severity of the clinical picture. Thus, the therapy and pathophysiology of this disease are a dilemma for health professionals and scientists. Objective: This paper aims to evaluate the effectiveness of therapeutic protocols (the use of anticoagulants) in the treatment of COVID-19 patients of various severity of the clinical picture by monitoring coagulation markers (PT, INR, aPTT and D-dimer), as well as the impact of the type and number of comorbidities patients had on these markers. Methods: A total of 200 patients with a mild (n=76), moderate (n=70) or severe (n=54) clinical picture was included. Coagulation markers [PT (prothrombin time), INR (international normalized ratio), aPTT (activated partial thromboplastin time), D-dimer] were examined on three occasions: twice during hospitalization and once after hospital discharge. Anticoagulants used intrahospital were fraxiparine, rivaroxaban or unfractionated heparin. Posthospital, patients were taking either rivaroxaban or did not use any anticoagulants. For statistical analysis, SPSS 26.0 and Microsoft Excel 2019 were used, with a level of significance of α=0.05. Nonparametric tests (Kruskal-Wallis, Wilcoxon Signed-Rank and Bonferroni) were applied and effect size (ES) was calculated. Results: Three anticoagulants used intrahospital caused a significant decrease in PT, INR and D-dimer and a significant increase in aPTT, especially in patients with a severe clinical picture, but the ES was the biggest with fraxiparine, then rivaroxaban, and lastly unfractionated heparin. Posthospital, rivaroxaban caused a significant decrease in PT, INR and D-dimer and a significant increase in aPTT, especially in patients with a severe clinical picture. Hypertension was the most common comorbidity in all patients, as well as in patients with a severe clinical picture. There was a statistically significant impact of the number of comorbidities patients had on D-dimer, and none on PT, INR and aPTT, but the highest number of comorbidities was in patients with a severe clinical picture. Conclusion: The use of anticoagulants, especially fraxiparine intrahospital and rivaroxaban posthospital, is justified in most COVID-19 cases as there is a significant correlation between this disease’s pathophysiology and the coagulation process. There is also a positive correlation between the severity of the clinical picture and the number of comorbidities patients have.
Coagulation biomarkers and coronavirus disease 2019 phenotyping: a prospective cohort study
Thrombosis Journal, 2023
Background Because severe acute respiratory syndrome coronarivus 2 (SARS-CoV-2) leads to severe conditions and thrombus formation, evaluation of the coagulation markers is important in determining the prognosis and phenotyping of patients with COVID-19. Methods In a prospective study that included 213 COVID-19 patients admitted to the intensive care unit (ICU) the levels of antithrombin, C-reactive protein (CRP); factors XI, XII, XIII; prothrombin and D-dimer were measured. Spearman's correlation coefficient was used to assess the pairwise correlations between the biomarkers. Hierarchical and non-hierarchical cluster analysis was performed using the levels of biomarkers to identify patients´ phenotypes. Multivariate binary regression was used to determine the association of the patient´s outcome with clinical variables and biomarker levels. Results The levels of factors XI and XIII were significantly higher in patients with less severe COVID-19, while factor XIII and antithrombin levels were significantly associated with mortality. These coagulation biomarkers were associated with the in-hospital survival of COVID-19 patients over and above the core clinical factors on admission. Hierarchical cluster analysis showed a cluster between factor XIII and antithrombin, and this hierarchical cluster was extended to CRP in the next step. Furthermore, a non-hierarchical K-means cluster analysis was performed, and two phenotypes were identified based on the CRP and antithrombin levels independently of clinical variables and were associated with mortality. Conclusion Coagulation biomarkers were associated with in-hospital survival of COVID-19 patients. Lower levels of factors XI, XII and XIII and prothrombin were associated with disease severity, while higher levels of both CRP and antithrombin clustered with worse prognosis. These results suggest the role of coagulation abnormalities in the development of COVID-19 and open the perspective of identifying subgroups of patients who would benefit more from interventions focused on regulating coagulation.
