University of Arkansas researches long-haul COVID-19 symptoms

A research team, led by  John Arthur, M.D., Ph.D., professor and chief of the Division of Nephrology in the UAMS College of Medicine, Department of Internal Medicine at the University of Arkansas for Medical Sciences, has identified a possible source for long-term symptoms experienced by COVID-19 patients, often referred to as long-haulers. 

As many as 30% of COVID-19 patients experience lingering fatigue, brain fog, and shortness of breath, puzzling many doctors and prompting the research.

researchers found nearly 81% of the plasma samples contained an antibody that attacked an enzyme that helps regulate that body’s immune system. The finding indicates that a second antibody emerges weeks after the initial infection, telling the body to continue its immune response and causing ongoing symptoms for patients.

The researchers plan to focus the next phase of their research on fatigue to figure out what mechanisms are involved and understand how to combat it.
