Extracellular deposition of protein as insoluble fibrils resulting in organ dysfunction. Many chronic inflammatory processes or infections can cause secondary amyloidosis (Amyloid A amyloidosis, systemic AA amyloidosis) due to deposition of a proteolytic fragment of serum amyloid A protein (SAA). The condition while rare is a feared complication of rheumatoid arthritis at up to 5% of patients[1] after 20 years as treatments remain experimental and survival from onset is often only a few years. Survival can be related to serum SAA concentration[2]. Staining with congo red is used to identify the amyloid.
Various forms of primary amylodosis exist such as:
- Familial mediterranean fever.
- Primary systemic (amyloid light-chain, or AL) amyloidosis
