Amyloidosis(AA type) with gastrointestinal involvement: Resolution of gastric amyloid deposition in parallel with disappearance of the serum component of amyloid a protein.

Abstract

The prognosis for secondary amyloidosis is better than that for the primary form. With arrest of the triggering disease, clinical improvement can be expected. Dramatic resolution of amyloid deposits, as proven by repeated biopsies, has been reported. We report on the effectiveness of amputation of the left thigh with chronic osteomyelitis in a patient with AA amyloidosis presenting with extensive amyloid involvement of the gastrointestinal tract and kidneys. Clinical improvement associated with reversibility of gastric amyloid deposition was observed in accordance with disappearance of the serum component of amyloid A protein.
