amiloosista

Amiloosis is a term that refers to a condition characterized by the abnormal accumulation of amyloid proteins within the body's tissues. Amyloid is a protein that normally exists in a soluble form. However, in amiloosis, this protein misfolds and aggregates into insoluble fibrils. These fibrils can deposit in various organs and tissues, including the heart, kidneys, liver, and nerves, leading to organ dysfunction and damage.

The underlying causes of amiloosis are diverse and can be broadly categorized into primary, secondary, and hereditary forms. Primary amiloosis, also known as AL amiloosis, is associated with a plasma cell disorder where abnormal immunoglobulin light chains are produced and misfold. Secondary amiloosis, or AA amiloosis, is often linked to chronic inflammatory conditions such as rheumatoid arthritis or inflammatory bowel disease, where chronic inflammation leads to the overproduction of serum amyloid A protein. Hereditary amiloosis is caused by genetic mutations that predispose individuals to the production of misfolded amyloid proteins.

Symptoms of amiloosis vary widely depending on the organs affected. Common manifestations can include fatigue, shortness of breath, swelling in the legs and abdomen, irregular heart rhythms, kidney problems, and neurological issues like numbness or weakness. Diagnosis typically involves a combination of medical history, physical examination, blood and urine tests, imaging studies, and tissue biopsies to confirm the presence and type of amyloid deposits. Treatment strategies aim to manage the underlying cause, reduce amyloid production, and alleviate symptoms to improve organ function and quality of life.
