@MondayNightIBD 2/Immune Checkpoint Inhibitor Enterocolitis
📌ICI = monoclonal antibodies that reactivate immune response to tumor cells
📌Activation of T‐cells can cross‐react with host antigens
📌Enterocolitis ⬆️anti‐CTLA‐4 > anti‐PD‐1/PD‐L1 agents
📌Diarrhea
⬆️risk perforation if unrecognized

📐R/o infection
🔦C-Scope: appearance of IBD; but mucosa can look normal -> always biopsy; consider EGD +Bx
🔬Path can have chronic IBD changes, crypt apoptosis
💊Depends on severity: budesonide -> IV steroids-> Biologic
