Systemic amyloidosis of beta 2-microglobulin type: a complication of long-term haemodialysis.

Abstract

A patient receiving long term haemodialysis developed systemic amyloidosis, which was shown immunohistochemically to be of .beta.2-microglobulin type, a previously unrecognised form of systemic amyloidosis. Histologically, the amyloid deposits were closely associated with foci of acute and granulomatous inflammation and vasculitis, although it was not clear if the amyloid deposits directly caused the inflammatory process, or if amyloid was deposited preferentially in areas of inflammation of uncertain aetiology.
