Overview
The kidney is the most involved organ in systemic amyloiosis. Suggested mechanisms of renal involvement include abnormal protein production or hereditary mutation.
Pathophysiology
Pathogenesis
- In systemic amyloidosis (AL/AH/AHL is much more common than AA) kidney is the most frequently involved organ.[1]
- In renal amyloidosis, the mechanisms of amyloidogenesis may include:[2]
- Abnormal protein production
- Overproduction wild-type proteins
- Decreased excretion of wild-type proteins
- Hereditary mutation
- In multiple myeloma, the cast nephropathy in distal tubules of nephrons results in renal impairment and deposition of AL amyloid protein in glomeruli can cause massive fibrillar involvement.[3]
Genetics
Hereditary amyloidosis due to amyloidogenic mutations:[4]
- Transthyretin (TTR) (most common inherited mutation)
- Fibrinogen
- Apolipoprotein A1
- Apolipoprotein A2
- Lysozyme
- Gelsolin genes
Associated Conditions
Gross Pathology
On gross pathology, amyloid looks "waxy" or "lardaceous" [7]
Microscopic Pathology
Microscopic Pathology of all types of amyloid after Congo red dye staining include: [2]
- Orange-red appearance by normal light microscopy
- Apple-green birefringence upon polarized light
