Researchers analyzed 203 patients hospitalized between March and June 2020 at the Unicamp HC, with 101 cases being positive for Covid-19 and 102 being negative.
The research titled Diagnosis of Covid-19 and its impact on thrombotic risk in a cohort of patients simultaneously hospitalized for Severe Acute Respiratory Syndrome – carried out by scientific initiation student Andréa Coy-Canguçu, under the guidance of the professor of the Department of Clinical Pathology of the Faculty of Medical Sciences (FCM) at Unicamp, Fernanda Orsi – received the main prize at the Latin American Congress of Hemostasis and Thrombosis ( CLAHT), held from August 18th to 21st, on an online platform.
“Previous evidence suggests that the thrombotic risk is greater in Covid-19 than in other types of severe acute respiratory syndrome (SARS). However, this comparison was based, above all, on the analysis of patients with SARS due to other etiologies hospitalized in years prior to the Covid-19 pandemic. Thus, our study sought to evaluate the incidence of thromboembolic events in patients hospitalized with a clinical condition compatible with SARS, due to Covid-19 or other etiologies, in the same period of time”, commented Fernanda.
The researchers analyzed 203 patients hospitalized for SARS between March and June 2020 at the Hospital de Clínicas da Unicamp, with 101 cases being positive for Covid-19 and 102 being negative. The results obtained revealed that, although high, the thrombotic risk in Covid-19 was similar to that found in other types of SARS.
"In addition to the number of patients affected by thrombotic events being similar between the study groups, we observed that there was no statistically relevant difference in relation to their D-dimer levels – a laboratory marker used in the suspicion of thrombosis. Thus, our study suggests that a state of blood hypercoagulability is inherent to SARS in general, regardless of whether the cause is Covid-19 or another pathology", explained the professor.
