[Amyloidosis secondary to bronchiectasis].

A 77-year-old woman was hospitalized repeatly due to frequent hemoptysis and production of bloodly sputum for several years. Bronchography in 1989 revealed bronchiectasis. She had complained of abdominal pain and diarrhea since 1991, and her urine was first positive for protein in 1992. She was admitted to our hospital in October 1992 because of edema, anemia, and hypoproteinemia. Despite treatment, renal dysfunction and the gastrointestinal disorder progressed and she died in January 1993. An autopsy revealed diffuse depositions of amyloid in many organs, especially in the kidney and the gastrointestinal tract. This amyloid protein was identified as AA protein, which was suggestive of secondary amyloidosis. Bronchiectasis appears to have been the disease underlying this patient's amyloidosis.
