Amyloidosis is a rare disease that occurs when proteins in the body accumulate in abnormal amounts and form amyloid proteins. These proteins can accumulate in various organs and tissues, causing damage and dysfunction. Amyloidosis can affect various organs and body systems, including the heart, kidneys, liver, nervous system, and skin. Symptoms of amyloidosis can vary depending on which organs and tissues are affected, and may include fatigue, weight loss, swelling, joint pain, heart, kidney, liver, nervous system and skin disorders.
Symptoms of amyloidosis
Symptoms of amyloidosis can be varied and depend on which organs and tissues are affected. Common symptoms may include fatigue, weight loss, swelling, and joint pain. However, symptoms may be nonspecific and may resemble those of other diseases, which can make it difficult to diagnose amyloidosis.
Symptoms associated with damage to specific organs and body systems may include:
Heart disorders: amyloid proteins can build up in the heart muscle, causing it to thicken and become dysfunctional. This can lead to palpitations, shortness of breath, swelling, and chest pain.
Kidney disorders: amyloid proteins can build up in the kidneys, causing damage and impaired kidney function. This may cause swelling, protein deposits in the urine, high blood pressure and impaired kidney function.
Liver disorders: amyloid proteins can build up in the liver, causing it to swell and become dysfunctional. This can lead to jaundice, increased abdominal size, impaired liver function, and other problems.
Nervous system disorders: amyloid proteins can build up in the nervous system, causing damage and dysfunction. This can lead to poor coordination of movement, loss of sensation, pain, and other problems.
Skin disorders: Amyloid proteins can accumulate in the skin, causing skin damage and dysfunction. This can lead to dry skin, itching, redness and other problems.
Types of amyloidosis
There are more than 30 different types of amyloidosis, which can vary in cause, location of amyloid proteins accumulation and symptoms. Some of the most common types of amyloidosis include:
- AL amyloidosis: this type of amyloidosis occurs when immune cells in the body produce abnormal proteins that then accumulate in tissues and organs. This type of amyloidosis can affect various organs and body systems, including the heart, kidneys, liver, and nervous system.
- AA amyloidosis: This type of amyloidosis occurs when the body fights infection or inflammation and produces abnormal proteins that then accumulate in tissues and organs. This type of amyloidosis can affect the kidneys, liver and other organs.
- ATTR amyloidosis: this type of amyloidosis occurs when abnormal proteins called transthyretin accumulate in tissues and organs. This type of amyloidosis can affect the heart, nervous system, and other organs.
Diagnosis and treatment
Diagnosing amyloidosis can be difficult because symptoms may be nonspecific and may resemble those of other diseases. Various tests and examinations can be used to diagnose amyloidosis, such as tissue biopsies, blood and urine tests, X-rays, and MRIs.
Treatment of amyloidosis depends on which organs and tissues are affected and how advanced the disease is. Drug therapy may include medications that help reduce the accumulation of amyloid proteins as well as medications that help improve organ and tissue function. In some cases, organ transplants or radiotherapy may be necessary.
Interesting Facts
- Amyloidosis was discovered in 1854 by German pathologist Rudolf Virchow.
- Amyloid proteins can accumulate in various organs and tissues, including the eyes, tongue, and bones.
- Some forms of amyloidosis may be hereditary.
- Treatment of amyloidosis can be complicated and requires a combination of different methods, including drug therapy, organ transplants, and radiotherapy.
