AA amyloidosis is a form of amyloidosis, 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 ...
AL amyloidosis is caused by the deposition of abnormal antibody free light chains. The abnormal light chains are produced by monoclonal plasma cells, and, although AL amyloidosis can occur without diagnosis of another disorder, it is often associated with other plasma cell disorders, such as multiple myeloma and Waldenström's macroglobulinemia.

[10] [46] Survival time is not associated with gender or age, however, some measures of reduced heart function are associated with a shorter survival time. [46] Senile systemic amyloidosis was determined to be the primary cause of death for 70% of people over 110 who have been autopsied. [47] [48]
Familial renal amyloidosis is a form of amyloidosis primarily presenting in the kidney. [1] It is associated most commonly with congenital mutations in the fibrinogen alpha chain and classified as a dysfibrinogenemia (see Hereditary Fibrinogen Aα-Chain Amyloidosis). [2] [3] and, less commonly, with congenital mutations in apolipoprotein A1 [4 ...
LECT2 Amyloidosis (ALECT2) is a form of amyloidosis caused by the LECT2 protein. It was found to be the third most common (~3% of total) cause of amyloidosis in a set of more than 4,000 individuals studied at the Mayo Clinic; the first and second most common forms the disorder were AL amyloidosis and AA amyloidosis, respectively.
Macular amyloidosis is a cutaneous condition characterized by itchy, brown, rippled macules usually located on the interscapular region of the back. [ 4 ] : 521 Combined cases of lichen and macular amyloidosis are termed biphasic amyloidosis, and provide support to the theory that these two variants of amyloidosis exist on the same disease ...
It is contrasted to systemic amyloidosis, and it can be caused by several different types of amyloid. [ 1 ] In almost all of the organ-specific pathologies, there is debate as to whether the amyloid plaques are the causal agent of the disease or instead a downstream consequence of a common idiopathic agent.
Amyloidosis is the accumulation of misfolded protein fibers in the body that can be associated with many chronic illnesses. Even though amyloidosis is common in chronic kidney disease (CKD) patients receiving chronic regular dialysis, it has also been reported in a patient with chronic kidney failure but who never received dialysis.
