title: Amyloidosis.
abstract: Amyloidosis is a disease involving the fibrillar deposition of proteins in a manner that uniformly leads to the presence of green birefringence on polarization microscopy after staining the involved tissues with Congo red. In the year summarized, a wide range of new information has accumulated about this disease. In this article, attention has been paid to several newly described proteins now known to precipitate into amyloid deposits, including the proteins transthyretin, apolipoprotein A-1, cystatin C, gelsolin, amyloid beta protein, beta 2-microglobulin, scrapie protein, and islet amyloid polypeptide. The number of these amyloid-related proteins has resulted in the need for a revised nomenclature and classification scheme. The results of a recent international symposium addressing this issue are summarized in table form. The varied clinical manifestations of amyloidosis are described according to organ system, with unusual or unique areas of involvement noted. Finally, the treatment of amyloidosis and its prognosis are addressed, and new areas of possible intervention suggested.
