Persistent Covid-19 In The Intestines May Drive Inflammation In Cancer Patients

New investigation from nan University of Minnesota Medical School is providing important insights into really COVID-19 persists successful crab patients moreover agelong aft testing positive. The findings were precocious published in iScience.

During a highest of COVID-19 successful 2020, location was interest astir crab patients who had contracted COVID-19 and developed terrible inflammatory reactions that looked akin to autoimmune conditions. To amended understand this phenomenon, researchers studied 3 crab patients who had undergone transplant therapies and were hospitalized pinch terrible COVID-19 infections.

The investigation squad discovered that moreover up to six weeks aft a patient's past affirmative nasal swab test, nan microorganism was still coming successful nan lining of their gut. The persistence of nan microorganism appeared to trigger accrued inflammation and harm to tissue. The researchers besides identified a circumstantial inflammatory marker, called SERPINA1, that was consistently linked to insubstantial inflammation successful these cases. 

"We learned that nan microorganism that causes COVID-19 infection lasted longer successful nan intestines than we would person predicted. More investigation is needed to find whether location is simply a nexus to Long COVID aliases different akin complications successful this at-risk population," added Emil Lou, MD, Ph.D., FACP, a physician-scientist and gastrointestinal oncologist pinch nan Masonic Cancer Center, and professor pinch tenure pinch nan University of Minnesota Medical School and M Health Fairview. 

Further investigation will purpose to study larger groups that person been infected pinch COVID-19. The researchers besides urge be aware astir patients pinch precocious levels of SERPINA1, who whitethorn request adjacent monitoring arsenic immoderate crab treatments could summation inflammation. 

This study was supported by Mrs. Hinda Litman and nan Litman Family Fund for Cancer Research, nan American Cancer Society, a University of Minnesota Data Science Initiative (DSI) Seed Grant, Friends and family of Gayle Huntington, nan Mu Sigma Chapter of nan Phi Gamma Delta Fraternity, University of Minnesota (FIJI), Dick and Lynnae Koats, Ms. Patricia Johnson and nan Love Like Laurie Legacy.
