- Introduction. Amyloidosis is a group of diseases in which a protein called amyloid builds up in the organs and tissues. The buildup may happen in a single organ (localized) or throughout the body (systemically). Amyloid deposits can affect any organ or tissue. There are three major types of systemic amyloidosis: 1  Primary amyloidosis (AL), the most common form, occurs when bone marrow produces too much of certain fragments of antibody proteins, which build up in the bloodstream and can deposit in body tissues.

Amyloidosis Amyloidosis is a group of diseases in which abnormal proteins, called amyloid proteins, accumulate in organs or organ systems such as the heart, kidneys, nervous system or gastrointestinal tract. There are different types of amyloidosis, dependent on the type of protein being deposited in tissues.

- Plaques form when protein pieces called beta-amyloid (BAY-tuh AM-uh-loyd) clump together. Beta-amyloid comes from a larger protein found in the fatty membrane surrounding nerve cells. Beta-amyloid is chemically sticky and gradually builds up into plaques. The most damaging form of beta-amyloid may be groups of a few pieces rather than the plaques themselves. The small clumps may block cell-to-cell signaling at synapses. They may also activate immune system cells that trigger inflammation and devour disabled cells.

Amyloidosis Other effects of amyloidosis include: 1  A burning sensation as a result of nerves being irritated by the amyloid. 2  Alternating bouts of constipation and diarrhea, if the protein deposits affect the nerves that control the bowels. 3  Bowel obstruction. 4  Carpal tunnel syndrome, which causes pain, numbness or tingling in the fingers.

amyloidosis familial amyloidosis any inherited form of amyloidosis; usually used to denote any of various systemic autosomal dominant disorders of amyloid deposition that involve the nervous system. The most common form, ATTR amyloidosis, is associated with mutations of the transthyretin protein, but rare mutations of other proteins can also be a cause.

Amyloidosis Amyloid is defined as in vivo deposited material distinguished by the following: 1  Fibrillar appearance on electron micrography. 2  Amorphous eosinophilic appearance on hematoxylin and eosin staining (see first image below) 3  Beta-pleated sheet structure as observed by x-ray diffraction pattern.

Amyloidosis In this Article. Amyloidosis is a condition in which an abnormal protein called amyloid builds up in your tissues and organs. When it does, it affects their shape and how they work. Amyloidosis is a serious health problem that can lead to life-threatening organ failure.

- Renal amyloidosis is inherited in Chinese Shar Pei dogs. Amyloidosis is a condition that occurs when amyloid protein is deposited in various organs in the body. It is a progressive disease that often leads to chronic kidney failure and is mostly seen in dogs, but rare in cats.

- Amyloidosis. Amyloidosis (see Amyloidosis) causes the protein amyloid to be deposited within blood vessels in the skin and subcutaneous tissues, which may increase the fragility of the blood vessels, causing purpura.

In spite of an apparent decrease in its occurrence during the last 2-3 decades, amyloidosis associated with rheumatoid arthritis is a significant cause of increased morbidity and early death in both juvenile- and adult-onset rheumatoid arthritis (RA).

Amyloidosis AA Amyloidosis is a group of diseases in which a protein, called amyloid, builds up in the body's organs and tissues. Amyloidosis AA is also referred to as Secondary amyloidosis or Inflammatory amyloidosis. This disease is caused by a long-lasting infection or inflammatory disease such as rheumatoid arthritis, familial Mediterranean fever, or osteomyelitis.

cerebral amyloid angiopathy Cerebral Amyloid Angiopathy. Definition. Cerebral amyloid angiopathy (CAA) is also known as congophilic angiopathy or cerebrovascular amyloidosis. It is a disease of small blood vessels in the brain in which deposits of amyloid protein in the vessel walls may lead to stroke, brain hemorrhage, or dementia.

Amyloid Neuropathy Amyloid Neuropathy. Disorders of peripheral nerves are the most common neurological complications of systemic amyloidosis; an illness where a protein called amyloid is deposited in tissues and organs. Amyloidosis can affect peripheral sensory, motor or autonomic nerves and deposition of amyloid lead to degeneration and dysfunction in these nerves.

Organ-limited amyloidosis [edit on Wikidata]. Organ-limited amyloidosis is a category of amyloidosis where the distribution can be associated primarily with a single organ. It is contrasted to systemic amyloidosis, and it can be caused by several different types of amyloid. In almost all of the organ-specific pathologies, there is significant debate as to whether the amyloid plaques are the causal agent of the disease or instead a downstream consequence of a common idiopathic agent. The associated proteins are indicated in parentheses.

- The many forms of localized amyloidosis are a result of amyloid deposits in specific areas of the body and are distinct from systemic forms of amyloidosis that deposit amyloid throughout the body. Localized amyloid deposits occur in the brain from Alzheimer's disease.myloid protein can be deposited in a localized area and may not be harmful or only affect a single tissue of the body impairing its function. This form of amyloidosis is called localized amyloidosis. Amyloidosis that affects many tissues throughout the body is referred to as systemic amyloidosis.

Amyloidosis The risk of developing amyloidosis is greater in people who: 1  Are older than 50. 2  Have a chronic infection or inflammatory disease. 3  Have a family history of amyloidosis. 4  Have multiple myeloma. 5  Have a kidney disease that has required dialysis for more than five years.

Amyloidosis Amyloidosis is a disease that leads to the buildup of protein in vital organs, which causes these organs to become damaged. Our bodies make several proteins that can cause amyloidosis. In order to treat a patient who has amyloidosis, it’s very important to know the exact protein that is causing the disease.

Amyloidosis Amyloidosis is a systemic disorder that is classified into several types. The different types of systemic amyloidosis are classified as primary, secondary or familial (hereditary). Primary amyloidosis (also called AL, or ‘light chain') is the most common type of systemic amyloidosis. AL results from an abnormality (dyscrasia) of plasma cells (a type of white blood cell) in the bone marrow and is closely related to multiple myeloma.

- This is the most common type of amyloidosis. Systemic means it affects the entire body. The most commonly affected body parts are the kidney, heart, liver, intestines, and certain nerves. AL stands for amyloid light chains, which is the type of protein responsible for this type of amyloidosis.
