Living with AA amyloidosis

A condition in which a protein builds up in organs, usually starting in the kidneys, after long-lasting infection or inflammation.

Understanding AA amyloidosis

AA amyloidosis is a condition in which a protein called amyloid builds up in the body's organs and tissues.

It is also called secondary or inflammatory amyloidosis. It is caused by a long-lasting infection or inflammatory disease such as rheumatoid arthritis, familial Mediterranean fever, or osteomyelitis. These raise serum amyloid A (SAA) protein, which forms deposits around cells. It usually starts in the kidneys, but the liver and spleen can also be affected. GARD lists onset as from childhood to adulthood.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Kidney disease (nephrotic syndrome)
  • Abdominal pain
  • Nausea and vomiting
  • Chronic diarrhea
  • Enlarged liver
  • Low blood pressure

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include autoimmune and inflammatory disease specialists, brain and nervous system specialists, heart and blood vessel specialists and kidney specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Amyloidosis Support Groups Inc., Amyloidosis Foundation and Amyloidosis Research Consortium may keep lists of experts for this condition.
