Refractory Intestinal Behçet-Like Disease Associated with Trisomy 8 Myelodysplastic Syndrome Resolved by Parenteral...

Intestinal Behçet disease (BD), associated with myelodysplastic syndrome (MDS), is often refractory to treatment. An 80-year-old man with trisomy 8 MDS (refractory anemia) developed intermittent fever. Despite investigations to exclude infectious disease, autoimmune disease, and malignancy as the cause of the fever, the etiology could not be determined. A colonoscopy revealed several shallow round ulcers in the ileocecal region and ascending colon, and the biopsy specimens showed nonspecific inflammation. Thereafter, the patient experienced abdominal pain and diarrhea. Other than an oral aphthous ulcer, the patient did not show symptoms to meet the diagnostic criteria for BD. The patient was diagnosed with intestinal ulcers (intestinal BD-like disease) with MDS and trisomy 8. After treatment failure with 5-aminosalicylic acid, steroid, colchicine, and azacitidine, cerebral infarction occurred. Eating was difficult because of the patient's impaired consciousness; hence, total parenteral nutrition (TPN) was commenced. The fever and abdominal symptoms improved with bowel rest over approximately 1 month. Small amounts of food were orally administered to the patient following recovery from the after-effects of the cerebral infarction, but diarrhea and fever repeatedly flared up. Therefore, TPN was continued at home. The patient has not experienced any further intestinal BD symptoms for approximately 1 year with bowel rest. Nutritional therapy, including bowel rest, may be an effective treatment option for intestinal BD with MDS, and might be used as an induction therapy of remission or a supportive therapy for other treatments.
