[Nephrologic aspects of amyloidosis].

Amyloidosis is a syndrome characterized by intercellular deposition of a predominantly proteic substance in any organ and tissue. The kidney is one of the most affected organs and very important in as much as its involvements might produce the initial manifestations of the syndrome and could be the one responsible to establish the prognosis in many cases. In this paper, the most relevant features of the different types of renal amyloidosis (glomerular, vascular and tubulo-interstitial), and one special type of amyloidosis in patients on chronic hemodialysis and likewise other interesting aspects in the evolution of amyloidosis of kidney transplanted patients were reviewed. Emphasis was placed on renal vascular amyloidosis and on amyloidosis among patients on hemodialysis as these might deserve special clinical and etiopathogenic considerations according to our own experience.
