Potential causes of increased duodenal IELs include celiac disease, gastric Helicobacter infection (not seen), giardia (not seen), stasis/bacterial overgrowth, post-infectious states including post-viral gastroenteritis (which can spontaneously resolve), medications (such as NSAIDs and olmesartan), wheat-protein allergy (usually TTG negative), tropical sprue, agammaglobulinemia (unlikely as plasma cells present) and other protein allergies. |
