Amyloidosis AA



Other Names:
Amyloid A amyloidosis; AA Amyloidosis
Categories:

Amyloidosis is a group of diseases in which a protein, called amyloid, builds up in the body's organs and tissues. Amyloidosis AA is also referred to as Secondary amyloidosis or Inflammatory amyloidosis. This disease is caused by a long-lasting infection or inflammatory disease such as rheumatoid arthritis, familial Mediterranean fever, or osteomyelitis. Infection or inflammation in the body causes an increased amount of a specific protein called serum amyloid A (SAA) protein. In this disease, part of the SAA protein forms deposits called "amyloid fibrils". These desposits occur in the space around the cells of certain tissues of the body. Amyloidosis AA usually begins as a disease in the kidneys, but other organs can be affected such as the liver and spleen. Medical or surgical treatment of the underlying infection or inflammatory disease can slow down or stop the progression of this condition.[1][2]

In amyloidosis AA, the treatment depends on the underlying disease. It is important to control the chronic infection or inflammatory disease which is responsible for the amyloid. Both surgery and medication can be used to achieve successful treatment outcomes for patients.

Medscape Reference provides current and comprehensive information on medical treatment options for amyloidosis AA based on the underlying inflammatory disease or infection. Please visit the link below. You may need to register to view the article, but registration is free.

Kidney transplant is an important option in patients with amyloidosis AA in which stable control of the underlying disease has been achieved. However, appropriate patient selection is strongly recommended due to a higher incidence of heart failure and infections in AA individuals.[3]

Currently there is a clinical study on the safety and effectiveness of the medication KIACTA in preventing decline of renal function in patients with amyloidosis AA. CLICK HERE to learn more about this study including the six study locations within the United States.

Management Guidelines


Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.

Clinical Research Resources

  • ClinicalTrials.gov lists trials that are related to Amyloidosis AA. Click on the link to go to ClinicalTrials.gov to read descriptions of these studies.

    Please note: Studies listed on the ClinicalTrials.gov website are listed for informational purposes only; being listed does not reflect an endorsement by GARD or the NIH. We strongly recommend that you talk with a trusted healthcare provider before choosing to participate in any clinical study.

Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.

Organizations Supporting this Disease

Social Networking Websites

  • RareConnect has an online community for patients and families with this condition so they can connect with others and share their experiences living with a rare disease. The project is a joint collaboration between EURORDIS (European Rare Disease Organisation) and NORD (National Organization for Rare Disorders).

These resources provide more information about this condition or associated symptoms. The in-depth resources contain medical and scientific language that may be hard to understand. You may want to review these resources with a medical professional.

Where to Start

  • The Mayo Clinic provides information on the diagnosis and treatment of amyloidosis.
  • Amyloidosis Awareness is an illustrated booklet for patients and physicians developed by Amyloidosis Support Groups Inc. Versions of the booklet are also available in Spanish and Portuguese.

In-Depth Information

  • Medscape Reference provides information on this topic. You may need to register to view the medical textbook, but registration is free.
  • The Monarch Initiative brings together data about this condition from humans and other species to help physicians and biomedical researchers. Monarch’s tools are designed to make it easier to compare the signs and symptoms (phenotypes) of different diseases and discover common features. This initiative is a collaboration between several academic institutions across the world and is funded by the National Institutes of Health. Visit the website to explore the biology of this condition.
  • PubMed is a searchable database of medical literature and lists journal articles that discuss Amyloidosis AA. Click on the link to view a sample search on this topic.

Questions sent to GARD may be posted here if the information could be helpful to others. We remove all identifying information when posting a question to protect your privacy. If you do not want your question posted, please let us know. Submit a new question

  • My husband was recently diagnosed with Amyloidosis AA. I was wondering what the most current treatments are for this disease. He has been treated with the medication Remicade in the past. See answer
