Bowel-associated dermatosis-arthritis syndrome (Q65246)

Bowel‐associated dermatosis–arthritis syndrome (BADAS) is a chronic relapsing disorder characterised by intermittent episodes of polyarthralgia, flu‐like symptoms and a papulopustular vasculitic rash. It is associated with gastrointestinal surgery, including bowel bypass procedures and bariatric surgery, but may also arise in other conditions such as inflammatory bowel disease or diverticulosis in which abnormal bacterial overgrowth may occur. It is thought that antibodies to bacterial cell wall peptidoglycans play an important role.
