Comprehensive, detailed thread on gastrointestinal effects of Covid from @GringoGranadino, one of the wonderful curators of CovidResearch.net
Gut microbiome alterations and gut barrier dysfunction are associated with host immune homeostasis in COVID-19 patients Our results suggest that the dysbiosis of the gut microbiome and the dysfunction of the gut barrier might play a role in the pathophysiology of COVID-19 by affecting host immune homeostasis.
Approximately one-half of COVID-19 patients shed fecal RNA in the week after diagnosis • Four percent of patients with COVID-19 shed fecal viral RNA 7 months after diagnosis • Presence of fecal SARS-CoV-2 RNA is associated with gastrointestinal symptoms • SARS-CoV-2 likely infects gastrointestinal tissue
Analysis thread on Twitter 1/3 Viral persistence and spike shedding may decrease the amount of ACE2 in some cell types and tissues. 2012 research showed that knock-out of the ACE2 gene in mice resulted in greatly increased inflammation in the gut following intestinal damage.
Anecdote This entire thread hits home. The GI issues from gastroparesis, GI bleeding and possibility of crohn's disease after having COVID is a hellscape I wasn't expecting. I expected the heart, lung and blood issues, but not the gastro issues.
