AMYLOID KIDNEY Meaning and
Definition
-
Amyloid kidney is a medical term referring to a condition characterized by the accumulation of abnormal proteins called amyloids within the renal structures. The amyloids are typically insoluble fibers that build up in the kidneys, interfering with their normal function. The accumulation of these proteins results in damage and dysfunction of the renal tissues, leading to various symptoms and complications.
Amyloidosis is the underlying condition that can affect multiple organ systems, including the kidneys. Amyloids are formed by the misfolding of certain proteins, usually produced in the bone marrow, and they can deposit in various organs. When these amyloid proteins deposit in the kidneys, it is referred to as amyloid kidney.
The presence of amyloids in the kidneys can cause several consequences. It can impair the kidneys' ability to filter waste products from the blood, leading to proteinuria (excretion of proteins in the urine) and eventually resulting in chronic kidney disease. Additionally, amyloid deposition can cause inflammation, which further exacerbates kidney damage. Symptoms of amyloid kidney include fatigue, weakness, fluid retention, high blood pressure, and diminished kidney function.
Diagnosing amyloid kidney typically involves a combination of laboratory tests, imaging studies, and a kidney biopsy to confirm the presence of amyloid deposits. Treatment options depend on the extent of kidney damage, but they often focus on managing symptoms and slowing the progression of renal dysfunction. This can involve medications to control blood pressure, manage proteinuria, and in severe cases, kidney transplantation.

Amyloid degeneration of the kidneys, associated usually with a similar process in the spleen and liver, caused frequently by prolonged suppuration; the kidneys are large, firm, and pale, the cortex being especially thickened and having a glistening appearance on section; the infiltration of amyloid material affects first the glomeruli and later the tubules as well.

Etymology of AMYLOID KIDNEY
The term "amyloid kidney" is derived from two main components: "amyloid" and "kidney".
The term "amyloid" originates from the Latin word "amylum", which means "starch". In the mid-19th century, Rudolph Virchow, a German pathologist, discovered an abnormal substance that resembled starch in the tissues of patients with a certain type of kidney disease. He named this substance "amyloid" due to its staining characteristics, which resembled the staining properties of starch. The term "amyloid" is now used to refer to a group of abnormal proteins that can accumulate in various organs and tissues.
The word "kidney" simply refers to one of the vital organs of the human body responsible for filtering waste products from the blood, regulating fluid balance, and producing urine.
