Rotational Thromboelastometry Reveals Distinct Coagulation Profiles for Patients With COVID-19 Depending on Disease Severity.

Identifying a hypercoagulable state in patients with COVID-19 may help identify those at risk for virus-induced thromboembolic events and improve clinical outcomes using personalized therapeutic approaches. Herein, we aimed to perform a global assessment of the patients' hemostatic system with COVID-19 using rotational thromboelastometry (ROTEM) and to describe whether patients with different disease severities present different coagulation profiles. Together with 37 healthy volunteers, a total of 65 patients were included and then classified as having mild, moderate, and severe disease depending on clinical severity. Peripheral blood samples were collected and analyzed using a ROTEM Coagulation Analyzer. Also, complete blood count and coagulation parameters including prothrombin time, activated partial thromboplastin time, fibrinogen levels, and D-dimer levels were measured at admission. EXTEM and INTEM MCF (P < 0.001) values were significantly higher and the EXTEM CFT (P = 0.002) value was significantly lower in patients with COVID-19 when compared with controls. In particular, patients with the severe disease showed a significant decrease in CFT (P < 0.001) and an increase in MCF (P < 0.001) in both INTEM and EXTEM assays compared with patients with the non-severe disease. Correlation analysis revealed significant correlations between ROTEM parameters and other coagulation parameters. There were significant positive correlations between fibrinogen, D-dimer, platelet count, and MCF in both EXTEM and INTEM assays. Our data demonstrate thromboelastographic signs of hypercoagulability in patients with COVID-19, which is more pronounced in patients with increased disease severity. Therefore, ROTEM analysis can classify subsets of patients with COVID-19 at significant thrombotic risk and assist in clinical decisions.

Validation and reliability of the Turkish version of the inflammatory bowel disease questionnaire for ulcerative colitis and Crohn's disease.

BACKGROUND/AIMS: Inflammatory bowel diseases (IBD) impairs patients' quality of life (QoL). Inflammatory bowel disease questionnaire (IBDQ) is created to measure the health-related QoL specific for IBD. We planned to investigate the validation and reliability of the Turkish translation of IBDQ. MATERIALS AND METHODS: Patients filled self-report questionnaires (Turkish Inflammatory bowel disease questionnaire (TrIBDQ) and Short Form-36 (SF-36)) themselves under a physician's supervision, and they were free to ask questions about the questionnaires. The participants then filled the same questionnaire after at least two weeks. Construct validity, discriminant ability, reliability, and susceptibility to change were analyzed separately for the IBD patients. Intra-class correlation coefficient (ICC) was used to assess test-retest reliability. Cronbach's alpha values were used to assess internal consistency. RESULTS: A hundred patients enrolled in the study, 53 with Crohn's disease (CD), 47 with ulcerative colitis (UC). We found a moderate to high positive correlation between the TrIBDQ domains and the SF-36 dimensions. In UC and CD, TrIBDQ was able to differentiate active disease and remission. We found Cronbach's alpha for TrIBDQ domains ranged from 0.76-0.94 in CD and from 0.79-0.92 in UC. The total Cronbach's alpha for TrIBDQ was 0.96 in CD and 0.95 in UC. Sensitivity-to-change analyses of the bowel, systemic, and emotional scores showed statistically significant differences between their baseline and follow-up values. CONCLUSION: TrIBDQ is a valid and reliable tool for assessing the quality of life in Turkish speaking IBD patients. Thus it can be used in clinical research and practice.
