Rheumatoid Arthritis | Intestinal Ischemia or Infarction

• unexplained abdominal pain including intestinal angina?

• evidence of bowel infarction?

• rheumatoid vasculitis elsewhere?

• an overlap syndrome with psoriatic arthritis or a sponyloarthropathy?

• elevated intestinal isoenzyme for alkaline phosphatase?

Does histology of the bowel wall show necrotizing vasculitis, arteritis or obliterative endarteritis?

Is there another vascular disease such as atherosclerosis that can explain the findings better?
