Abstract
A 41-year-old man was admitted to our hospital because of face and leg edema. Blood examination revealed hypoalbuminemia and positive reaction for anti-nuclear antibodies and anti-Sm antibodies. Abdominal scintigram using 99mTc-labeled human albumin revealed abnormal radioactivity in the ascending and transverse colon, suggesting albumin losing from terminal ileum or ascending colon. Colonoscopy revealed slight reddish mucosa and histology of biopsy specimen showed mild edema and inflammatory cell infiltration. Immunofluorescense study revealed deposition of C3 in the endothelium of colonic mucosa. Diagnosis of autoimmune protein-losing enteropathy was made. Steroid therapy was not effective and cyclophosphamide pulse therapy resulted in a significant recovery of serum albumin level and improvement of clinical symptoms.
