AA amyloidosis is a form of amyloidosis, i.e. a disease characterized by the abnormal deposition of fibers of insoluble protein in the extracellular space of various tissues and organs. In AA amyloidosis, the deposited protein is serum amyloid A protein (SAA), an acute-phase protein which is normally soluble and whose plasma concentration is highest during inflammation.[1]


AA amyloidosis is a complication of a number of inflammatory diseases and infections.:[2]


The SAA protein is mainly deposited in the liver, spleen and kidney, and AA amyloidosis can lead to nephrotic syndrome.[6][7]

Current Clinical Research[edit]

Kiacta - (eprodisate disodium) is currently being evaluated as a protector of renal function in AA amyloidosis.
