Five blood biomarkers associated with clinical deterioration and high mortality odds in COVID-19 patients

 


Researchers at the George Washington University (GW) have discovered five biomarkers in the blood, medical indicators in the blood, associated with clinical odds and high odds of mortality in COVID-19 patients. Published in Future medicine, These findings help physicians better predict outcomes for COVID-19 patients in the United States

When I started to treat COVID-19 patients, I saw them get better and worse, but I didn’t know why. Some early studies from China showed that certain biomarkers were associated with poor outcomes. There was a desire to see if that would apply to patients here in the United States. “

Juan Reyes, MD, Co-author of Research, and Associate Professor of Medicine, GW School of Medicine and Health Sciences

The research team evaluated 299 patients diagnosed with COVID-19 admitted to GW Hospital between March 12 and May 9, 2020. Of these patients, 200 had all five biomarkers (IL-6, D dimer, CRP, LDH, ferritin. Elevated levels of these biomarkers were associated with inflammation and bleeding disorders, indicating an independently increased risk of ICU hospitalization, invasive ventilatory support, and death. The highest probability of death occurred when the LDH level was above 1200 units/l and the D-dimer level was above 3 μg/ml.

“These biomarkers can help with clinical decisions such as how aggressively a physician needs to treat a patient, whether the patient should be discharged, and how to monitor the patient during their return home.” I am a Medical Associate Professor at GW School of Medicine and School of Health Sciences.

Doctors are now determining the risk of COVID-19 exacerbation and death based on age and certain underlying conditions such as immunodeficiency, obesity, and heart disease. Performing simple blood tests on patients admitted to the emergency department and making decisions based on existing biomarkers may further support point-of-care clinical decision making. Research teams at Reyes, Ayanyan, and GW continue to analyze this data to help doctors make more informed decisions about patients and identify hospitals that need to stratify resources. We support.
