Hoel et al.34 assessed marker of intestinal epithelial cell damage (intestinal fatty acid-binding protein), marker of intestinal leakage (lipopolysaccharide-binding protein (LBP)), marker of intestinal homing (C-C chemokine motif ligand 25 (CCL25)), and markers of inflammasome activation (interleukin (IL)-1, IL-18) in plasma between 39 COVID-19 patients and 16 healthy controls. This evidence concerns the gene LBP and COVID-19.
