A first study of its kind shows that gut microbes could predict how seriously ill a Covid-19 patient might become. In the hopes to identify why some individuals with COVID-19 fare better than others, researchers created a risk score based on blood biomarkers found in severe COVID-19 patients. Scientists found that these biomarkers are linked closely with a core set of gut microbiome characteristics, as well as with increased inflammatory cytokines. COVID-19 is linked closely to the gut. As the virus enters the body, it binds to ACE2 enzymes, which play a large role in regulating intestinal inflammation and gut microbe make-up. COVID-19 patients who experience GI symptoms (diarrhea, nausea, and vomiting) also tend to suffer from a more severe state of the disease, so it makes sense that the gut microbiome and disease severity are strongly associated. MedRxiv Takeaway: Scientists who conducted the research concluded that based on the…
