Exploring blood clotting mechanisms in COVID-19 patients

Cellular Effects of SARS-CoV-2 in Mediating Thrombotic Susceptibility

Observational University of Iowa · NCT05334615

What this trial studies

This observational study at the University of Iowa aims to investigate the mechanisms behind enhanced thrombin generation in hospitalized COVID-19 patients. By collecting blood samples from patients at enrollment and weekly for up to 30 days, the study will analyze the activation of blood cells and their role in coagulopathy associated with COVID-19. The research builds on previous findings that suggest a link between COVID-19 and increased thrombin generation, which may contribute to severe complications. The longitudinal cohort design will provide insights into the duration and nature of these changes during hospitalization.

Who should consider this trial

Good fit: Ideal candidates include hospitalized adults aged 18 and older with confirmed COVID-19 or incidental COVID-19 infections.

Not a fit: Patients with a history of bleeding disorders, active cancer, or those who are pregnant will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better understanding and management of coagulopathy in COVID-19 patients, potentially improving patient outcomes.

How similar studies have performed: Other studies have shown potential links between COVID-19 and coagulopathy, but this specific mechanistic exploration is novel.
