Cerebral Amyloid Angiopathy Cerebral amyloid angiopathy (CAA) refers to the deposition of β-amyloid in the media and adventitia of small and mid-sized arteries (and, less frequently, veins) of the cerebral cortex and the leptomeninges.It is a component of any disorder in which amyloid is deposited in the brain, and it is not associated with systemic amyloidosis.

- Definition and Historical Background. A keloid is an abnormal proliferation of scar tissue that forms at the site of cutaneous injury (eg, on the site of a surgical incision or trauma); it does not regress and grows beyond the original margins of the scar.

- If amyloidosis affects your heart, you may have: 1  Shortness of breath with light activity. 2  An irregular heartbeat. 3  Signs of heart failure, including swelling of the feet and ankles, weakness, fatigue, and nausea, among others.

nephrosis nephrosis. disease characterized by purely degenerative lesions of the renal tubules. amyloid nephrosis. chronic nephrosis with amyloid deposition in glomerular capillaries, in basement membranes of tubules and eventually around tubules.biliary nephrosis. the renal component of acute hepatic failure characterized by oliguria and azotemia. infectious avian nephrosis. see infectious bursal disease.ower nephron nephrosis renal insufficiency leading to uremia, due to necrosis of the lower nephron cells that blocks the tubular lumens of this region; seen after severe injuries, especially crushing injury to muscles.

Signs and Symptoms Many of these symptoms are general and can occur in other diseases. It is because of this that a diagnosis is sometimes difficult. In primary (AL) amyloidosis the organs most often involved include the heart, kidneys, nervous system, and gastrointestinal tract.

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.

- 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 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.

Amyloidosis General Discussion. 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.

AA Amyloidosis AA Amyloidosis. AA amyloidosis occurs as a reaction to another illness, such as a chronic inflammatory disease or a chronic infection. Infections and inflammation cause the liver to produce a protein called SAA (serum amyloid A protein) in high levels. This is a normal reaction.

- Familial (hereditary) amyloidosis is a genetic form passed down in families that often affects nerves and kidneys. Secondary amyloidosis (AA) develops along with a chronic infectious or inflammatory disease, such as tuberculosis or rheumatoid arthritis.

- Secondary amyloidosis is amyloidosis that occurs as a byproduct of another illness, including chronic infections (such as tuberculosis or osteomyelitis), or chronic inflammatory diseases (such as rheumatoid arthritis, ankylosing spondylitis, and inflammatory bowel disease).

Diabetic angiopathy--its lessons in vascular physiology. McMillan DE. Progress in our understanding diabetic angiopathy has been slow, but we are now learning a number of lessons of interest to the cardiologist. Diabetic angiopathy is a collective term for conditions specific to the diabetic state and related to its duration more than to patient age. The angiopathy produces calcification of the media of larger arteries, but its major effects are in the microcirculation.

senile cardiac amyloid Cardiac amyloidosis Cardiology A disorder caused by myocardial deposition of amyloid protein with compromised cardiac function, causing restrictive cardiomyopathy or dilated cardiomyopathy, which may be associated with conduction defects; SCA is confined to the heart, usually occurring in older adults.

Diabetic Amyotrophy Diabetic amyotrophy,also known as proximal diabetic neuropathy, diabetic lumbosacral radiculoplexus neuropathy, and diabetic polyradiculoneuropathy, occurs in patients with diabetes (more likely in those with type II than type I).

Signs and Symptoms Amyloid deposits in these organs can cause shortness of breath, fatigue, edema (swelling of ankles and legs), dizziness upon standing, a feeling of fullness in the stomach (especially after eating), diarrhea, weight loss, enlarged tongue, numbness of the legs and arms, and protein in the urine.

Amyloidosis Familial amyloidosis is a rare type of amyloidosis that is caused by an abnormal gene. There are several abnormal genes that can cause hereditary amyloidosis, but the most common type of hereditary amyloidosis is called ATTR and caused by mutations in the transthyretin (TTR) gene.

- Cardiac (Heart) Amyloidosis. Amyloid deposits in the heart can make the walls of the heart muscle stiff. They can also make the heart muscle weaker and affect the electrical rhythm of the heart. This condition can cause less blood to flow to your heart. Eventually, your heart will no longer be able to pump.

- Amyloidosis is a rare disease that is a consequence of abnormal protein (amyloid) deposits in body tissues and organs. Amyloidosis can occur as an isolated disease (primary amyloidosis) or as a result of another illness (secondary amyloidosis).

Autonomic Neuropathy Overview. Autonomic neuropathy (AN) is a condition that results from damage to nerves that assist in organ and organ system functioning. This nerve damage disturbs signal processing between the autonomic nervous system and the brain.

AL Amyloidosis Chronic kidney disease is common in patients with AL amyloidosis. Amyloid deposits in the kidneys can affect how they filter toxins and proteins in the blood. This may result in a condition called nephrotic syndrome, where there is excess protein in the urine and the lower legs can become swollen (also called “edema”).

Acute intermittent porphyria Acute intermittent porphyria. Acute intermittent porphyria (AIP) is a genetic metabolic disorder affecting the production of heme, the oxygen-binding prosthetic group of hemoglobin. It is characterized by a deficiency of the enzyme porphobilinogen deaminase.

Acute intermittent porphyria Summary Summary. Listen. Acute intermittent porphyria (AIP) is one of the liver (hepatic) porphyrias. AIP is caused by low levels of porphobilinogen deaminase (PBGD), an enzyme also often called hydroxymethylbilane synthase.
