Assessing blood levels of mediators in COVID-19 patients

COVID-19 RELATED SUBMISSION: VEGF and sFlt-1 Levels in the Pathogenesis and Severity of COVID-19 Disease

Observational University of Alabama at Birmingham · NCT04587323

This study is trying to see how certain substances in the blood of COVID-19 patients might affect their health and why some people with heart issues get sicker than others.

What this trial studies

This observational study aims to evaluate the blood levels of vasoactive mediators that may influence pulmonary endothelial permeability and contribute to multi-organ injury in patients with COVID-19. The study will correlate these levels with various disease outcomes, including ICU admission, length of ventilatory support, and instances of respiratory, kidney, and heart failure. By comparing patients with preexisting cardiovascular conditions to those without, the research seeks to understand why some individuals experience more severe symptoms. The findings could provide insights into the pathophysiology of COVID-19 and its impact on patients with underlying health issues.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older who have tested positive for COVID-19 and have available blood specimens.

Not a fit: Patients under 18 years old or those without a blood specimen will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of COVID-19 severity and inform treatment strategies for affected patients.

How similar studies have performed: While this study explores a specific pathway in COVID-19, similar approaches have shown promise in understanding other respiratory infections, indicating potential for success.
