Amyloidosis: Introduction

Amyloidosis: Proteins are important building blocks for all body parts, including muscles, bones, hair, and nails. Proteins circulate throughout the ... more about Amyloidosis.

Amyloidosis: A rare group of metabolic disorders where a protein called amyloid accumulates in body organs and tissues where it can cause damage and is potentially fatal. Symptoms depend on the organs involved. There are numerous forms of the condition: primary amyloidosis, secondary amyloidosis, hemodialysis-associated amyloidosis and familial amyloidosis. More detailed information about the symptoms, causes, and treatments of Amyloidosis is available below.

Article Excerpts about Amyloidosis

Amyloidosis and Kidney Disease: NIDDK (Excerpt)

Proteins are important building blocks for all body parts, including muscles, bones, hair, and nails. Proteins circulate throughout the body in the blood and are normally harmless. Occasionally, cells produce abnormal proteins that can settle in body tissue, forming deposits and causing disease. When these deposits of abnormal proteins were first discovered, they were called amyloid, and the disease process amyloidosis. (Source: excerpt from Amyloidosis and Kidney Disease: NIDDK)

Kidney Failure Glossary: NIDDK (Excerpt)

A condition in which a protein-like material builds up in one or more organs. This material cannot be broken down and interferes with the normal function of that organ. People who have been on dialysis for several years often develop amyloidosis because the artificial membranes used in dialysis fail to filter the protein-like material out of the blood.

Definitions of Amyloidosis:

A disease characterised by the deposition of amyloid in various organs of the body. It is generally considered that the amyloidoses share common pathogenic mechanisms which lead to protein fibril formation and deposition. These mechanisms may include structural, metabolic, genetic and environmental factors that may be common to all forms of amyloidosis. Primary amyloidosis, while the most common form of amyloidosis, is a sporadic disease and, therefore, can only be investigated on a case by case basis. Secondary (reactive) amyloidosis occurs in subjects with chronic inflammatory disease or cancer but factors which predict amyloid formation and which subject is going to be affected, are not readily apparent. Alzheimer disease, while very common in the aged population, is unpredictable except for those rare forms of familial Alzheimer disease with characterized mutations in specific genes. Hereditary transthyretin amyloidosis has generally been considered a rare disease and the original impetus to study the pathogenesis of this disease was because it represented a human model of systemic amyloidosis. - (Source - Diseases Database)

Amyloidosis is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). This means that Amyloidosis, or a subtype of Amyloidosis, affects less than 200,000 people in the US population.

Ophanet, a consortium of European partners, currently defines a condition rare when it affects 1 person per 2,000. They list Amyloidosis as a "rare disease".
