COVID-19 & Diarrhea – Day 19, Thoughts About The Pandemic

Why do some patients get gastrointestinal symptoms such as diarrhea?

Daily thoughts & numbers on the COVID-19 pandemic from a M.D. working in the front lines at the Emergency Department in a hospital in Stockholm, Sweden. 

Clin Gastroenterol Hepatol 2020-04-08 article by D’Amico et al, ‘Diarrhea during COVID-19 infection: pathogenesis, epidemiology, prevention and management‘: *

RESULTS:

Clinical studies show an incidence rate of diarrhea ranging from 2% to 50% of cases. It may precede or trail respiratory symptoms. A pooled analysis revealed an overall percentage of diarrhea onset of 10.4%. SARS-CoV uses the the angiotensin-converting enzyme 2 (ACE2) and the serine protease TMPRSS2 for S protein priming. ACE2 and TMPRSS2 are not only expressed in lung, but also in the small intestinal epithelia. ACE2 is expressed furthermore in the upper esophagus, liver, and colon. SARS-CoV-2 binding affinity to ACE2 is significantly higher (10-20 times) compared with SARS-CoV. Several reports indicate viral RNA shedding in stool detectable longer time period than in nasopharyngeal swabs. Current treatment is supportive, but several options appear promising and are the subject of investigation.

So, in other words, we have ACE2 receptors in our guts too, therefor diarrhea in some patients.

Looks like this:
