Primary AL-amyloidosis, ulcerative colitis and collagenous colitis in a 57-year-old woman: a case study.

A 57-year-old woman with AL-amyloid deposits in the heart, gastrointestinal tract and the liver developed ulcerative colitis, which was treated with glucocorticosteroids and 5-aminosalicylic acid, with good response. The AL-amyloidosis was successfully treated with high-dose chemotherapy and autologous stem-cell transplantation. The patient was in good clinical condition for 18 months after treatment, until she developed diarrhea, which was found to be due to collagenous colitis. Two years after treatment of amyloidosis, the patient is in excellent condition, the symptoms of heart failure have stabilized and no adverse effects of the treatment regime have been observed. The bowel diseases are in clinical remission.
