Background: The purpose of this study is to evaluate the prognostic roles of hemostatic tests including prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen, D-dimer, and antithrombin III in the progression of disease, monitorization of severe, mild and moderate cases, and also to show their relationship with inflammatory markers including C-reactive protein (CRP), procalcitonin, and interleukin-6 (IL-6).
Methods: The study comprised 604 patients (360 men and 244 women) with confirmed SARS-CoV-2 infection admitted to Emergency Department of Istanbul Faculty of Medicine between March 15 and April 15, 2020. The variations in the concentration of coagulation tests and inflammatory markers were observed from the admission to hospital to the 10th day with three-day periods.
Results: PT level and PT activity of severe cases were significantly different compared to mild cases (p = 0.012, p = 0.010, respectively). Similarly, aPTT and D-dimer levels in severe cases were significantly higher compared to the mild cases. However, fibrinogen levels of mild cases were significantly lower compared to either moderate or severe cases (p < 0.001, for both). The PT, PT activity, aPTT, and D-Dimer levels in severe cases were significantly different compared with the mild cases. However, fibrinogen level was the highest in severe cases, and higher than either mild or moderate cases.
Conclusions: Our findings reveal the vital importance of measuring coagulation parameters at the time of admission and monitoring them at regular intervals in clinical monitoring of COVID-19 patients, in determining the severity of the disease in terms of the patient's prognosis, and in choosing and applying the appropriate treatment at the right time.
