COVID and GI

 Q: In patients with inflammatory bowel disease (IBD), use of which of the following is found to have increased risk of COVID-19? (select one) 

 A) glucocorticoids 

B) anti-TNF therapy 


 Answer:

Overall patients with IBD have found to have no higher risk than the general population to acquire COVID-19, although patients on active treatment may have higher risk. Surprisingly, patients on glucocorticoids are found to have higher risk than patients on anti-TNF therapy (TNF = Tumor necrosis Factor). 

The gastrointestinal (GI) symptoms in COVID are due to the presence of widely expressed angiotensin-converting enzyme 2 (ACE2) receptors in the intestine. They are most prevalent in the cytoplasm of gastric cells, intestinal epithelial cells, and the cilia of glandular epithelial cells.

Caution: Literature on COVID-19 is still evolving.
