What kind of doctor treats Primary Amyloidosis?

A primary care doctor often notices the first signs and orders early tests. Most people are then referred to a hematologist, a blood specialist who directs treatment. Depending on the organs involved, patients may also see a cardiologist or nephrologist.

What is primary amyloidosis?

Primary amyloidosis, also called AL amyloidosis, is a rare disease in which abnormal proteins called amyloid build up in organs and damage them. It starts in the bone marrow, the soft tissue inside bones that makes blood cells. It can affect the heart, kidneys, liver, nerves, and other parts of the body.

Amyloidosis happens when the body makes misshapen proteins it cannot break down. These proteins clump together and settle in organs, making it harder for them to work normally. Primary amyloidosis is linked to abnormal bone marrow cells.

Symptoms

Symptoms depend on which organs are affected. Many people feel very tired and lose weight without trying. Some have leg swelling, shortness of breath, or numbness and tingling in the hands and feet. Others notice a purplish rash around the eyes or easy bruising.

Causes and who gets it

Primary amyloidosis is not usually inherited. It begins when plasma cells in the bone marrow make abnormal proteins, and doctors do not know why. It is rare, most often diagnosed after age 60, and affects men more often than women.

How doctors diagnose it

Doctors start with a physical exam and questions about symptoms. Blood and urine tests can show signs of the abnormal protein. A biopsy is often needed to confirm the diagnosis, and imaging such as an echocardiogram shows which organs are affected.

Treatment

Treatment focuses on lowering the abnormal protein the body makes, often with medicines similar to those used for other bone marrow conditions, such as chemotherapy drugs or targeted therapies. Some people may be candidates for a stem cell transplant. Results vary from person to person.

When to see a doctor

Anyone with ongoing fatigue, unexplained weight loss, leg swelling, shortness of breath, or numbness in the hands and feet should see a doctor. These symptoms usually have more common causes, but they deserve a checkup.

How a direct primary care or concierge doctor fits in

A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either type can order initial tests, monitor symptoms, and manage other health problems, but would refer the patient to a hematologist for this rare condition.

Common questions

Is primary amyloidosis cancer?

It is closely related to a bone marrow condition, and the abnormal plasma cells behave somewhat like cancer cells. Many doctors treat it with medicines used for blood cancers. A hematologist can explain what the diagnosis means for a specific person.

Is primary amyloidosis hereditary?

Most cases are not passed down in families. A different type of amyloidosis, called hereditary amyloidosis, does run in families. Genetic testing can help tell the types apart.

Can primary amyloidosis go away?

Treatment can lower the abnormal protein and help organs work better, but results differ from person to person. Some people have long periods of improvement. Ongoing follow-up care is usually needed.

How common is primary amyloidosis?

It is rare. In the United States, only a few thousand new cases are diagnosed each year. Because it is uncommon, many general doctors may see only a few cases in their careers.
