| [ Summary ] |
Non-steroidal anti-inflammatory drug (NSAID)-induced small intestinal lesions have become apparent with capsule endoscopy and balloon-assisted endoscopy. The mechanisms are intracellular mitochondrial damage, weakening of tight junctions between cells, apoptosis and necrosis, reduced mucus secretion and microcirculation disturbances due to COX-1 inhibition, and infl ammation due to invasion of bile acids, microbiota, proteolytic enzymes, and food. Involvement of dysbiosis by PPI has also been reported. Most symptoms are anemia, bloody stool, diarrhea, and abdominal pain. Endoscopic findings reveal redness, denuded areas, erosions, aphtoid ulcers, punched ulcers, annular ulcers, and diaphragm. Therapies are discontinuation of NSAIDs and changes to COX-2 selective inhibitors or other analgesics. Efficacy for prevention of mucosal protective drugs such as misoprostol and rebamipide, antibiotics, and probiotics have been reported. |
