Abstract

AA amyloidosis is a rare complication of chronic inflammatory diseases and is the second most common form of systemic amyloidosis after primary amyloidosis. The clinical presentation is based on the consequences of renal involvement, with proteinuria and progressive renal deterioration. Treatment focuses on controlling the underlying inflammatory process by reducing the supply of the amyloid A precursor protein, so that in patients with adequate suppression of this serum protein, regression of amyloid deposits can be observed and renal function can be stabilized or even improved.
