Amyloidosis vs. Multiple Myeloma

What's the Difference?

Amyloidosis and Multiple Myeloma are both diseases that affect the plasma cells in the body, but they have distinct differences. Amyloidosis is a condition where abnormal proteins called amyloids build up in various organs and tissues, causing damage and impairing their normal function. On the other hand, Multiple Myeloma is a type of cancer that specifically affects plasma cells in the bone marrow, causing them to multiply uncontrollably and produce abnormal antibodies. While both conditions can lead to organ damage, Multiple Myeloma is primarily characterized by bone pain, anemia, and weakened immune system, whereas Amyloidosis can affect a wider range of organs and present with symptoms specific to the affected organ. Treatment approaches for these diseases also differ, with Multiple Myeloma often requiring chemotherapy, stem cell transplantation, and targeted therapies, while Amyloidosis may involve managing the underlying cause, symptomatic treatment, and in some cases, organ transplantation.


AttributeAmyloidosisMultiple Myeloma
DefinitionA disorder characterized by the buildup of abnormal proteins called amyloids in various organs and tissues.A cancer of plasma cells, a type of white blood cell, which accumulate in the bone marrow and crowd out healthy blood cells.
CauseCan be caused by various underlying conditions, such as multiple myeloma, chronic infections, or autoimmune diseases.The exact cause is unknown, but it is thought to involve genetic mutations and environmental factors.
PrevalenceRelatively rare, affecting approximately 1 in 100,000 people per year.More common than amyloidosis, with an estimated 30,000 new cases in the United States each year.
Organs/Tissues AffectedAmyloid deposits can accumulate in various organs, including the heart, kidneys, liver, spleen, and nervous system.Primarily affects the bone marrow, but can also impact other organs such as the kidneys, bones, and immune system.
SymptomsCan vary depending on the organs affected but may include fatigue, shortness of breath, swelling, weight loss, and neurological issues.Common symptoms include bone pain, fatigue, recurrent infections, anemia, and kidney problems.
TreatmentTreatment options may include chemotherapy, stem cell transplantation, targeted therapy, and supportive care to manage symptoms.Treatment approaches may include chemotherapy, immunomodulatory drugs, targeted therapy, stem cell transplantation, and supportive care.

Further Detail


Amyloidosis and Multiple Myeloma are two distinct diseases that affect the human body in different ways. While both conditions involve the abnormal production and accumulation of proteins, they have unique characteristics and manifestations. In this article, we will explore the attributes of Amyloidosis and Multiple Myeloma, highlighting their differences and similarities.

Overview of Amyloidosis

Amyloidosis is a rare disorder characterized by the buildup of abnormal proteins called amyloids in various organs and tissues throughout the body. These amyloids are formed when misfolded proteins clump together and deposit in organs, interfering with their normal function. Amyloidosis can affect multiple organs, including the heart, kidneys, liver, spleen, and nervous system.

The symptoms of Amyloidosis can vary depending on the affected organs, but common signs include fatigue, weight loss, shortness of breath, swelling, and numbness or tingling in the extremities. The disease can progress slowly or rapidly, and if left untreated, it can lead to organ failure and potentially be life-threatening.

Overview of Multiple Myeloma

Multiple Myeloma, on the other hand, is a type of cancer that affects plasma cells, a type of white blood cell responsible for producing antibodies. In this condition, abnormal plasma cells accumulate in the bone marrow, crowding out healthy blood cells and impairing their function. Multiple Myeloma primarily affects the bones, but it can also impact other organs such as the kidneys.

The symptoms of Multiple Myeloma can include bone pain, fatigue, frequent infections, anemia, kidney problems, and increased susceptibility to fractures. As a cancerous condition, Multiple Myeloma can spread to other parts of the body if not treated promptly, leading to further complications and reduced life expectancy.

Causes and Risk Factors

The causes of Amyloidosis can vary depending on the specific type, as there are several forms of the disease. In some cases, Amyloidosis is inherited due to genetic mutations, while in others, it may be associated with chronic inflammatory conditions, such as rheumatoid arthritis or inflammatory bowel disease. Additionally, certain cancers, such as multiple myeloma or lymphoma, can also contribute to the development of Amyloidosis.

Multiple Myeloma, on the other hand, is primarily caused by genetic mutations in plasma cells. However, the exact triggers for these mutations are not yet fully understood. Certain risk factors, such as older age, male gender, family history of the disease, and exposure to radiation or certain chemicals, have been associated with an increased likelihood of developing Multiple Myeloma.

Diagnosis and Treatment

Diagnosing Amyloidosis typically involves a combination of medical history evaluation, physical examination, and various tests. These tests may include blood and urine tests to detect abnormal protein levels, imaging studies like X-rays or CT scans to identify organ involvement, and sometimes a biopsy of affected tissues to confirm the presence of amyloid deposits.

Treatment options for Amyloidosis depend on the specific type and severity of the disease, as well as the organs affected. In some cases, addressing the underlying cause, such as treating the associated cancer or inflammatory condition, may help manage Amyloidosis. Other treatment approaches may include medications to reduce the production of abnormal proteins, organ-specific therapies, or stem cell transplantation in severe cases.

Diagnosis and Treatment

Diagnosing Multiple Myeloma involves a series of tests, including blood and urine tests to detect abnormal protein levels, bone marrow biopsy to examine the presence of cancerous plasma cells, and imaging studies like X-rays or MRI scans to assess bone damage or organ involvement.

Treatment for Multiple Myeloma typically involves a combination of chemotherapy, targeted therapy, immunotherapy, and stem cell transplantation. The specific treatment plan depends on various factors, such as the stage of the disease, overall health of the patient, and individual preferences. The goal of treatment is to control the cancer, alleviate symptoms, and improve the patient's quality of life.

Prognosis and Outlook

The prognosis for Amyloidosis varies depending on the type and extent of organ involvement. Some forms of Amyloidosis have a better prognosis, especially if the underlying cause can be effectively treated. However, in severe cases where multiple organs are affected, the prognosis may be poor, and the disease can be life-threatening.

Multiple Myeloma has seen significant advancements in treatment options in recent years, leading to improved outcomes for many patients. However, the prognosis still depends on various factors, including the stage of the disease at diagnosis, response to treatment, and overall health of the individual. With early detection and appropriate treatment, many individuals with Multiple Myeloma can achieve remission and enjoy an extended period of disease control.


Amyloidosis and Multiple Myeloma are distinct diseases with unique characteristics, although they both involve the abnormal accumulation of proteins. Amyloidosis affects multiple organs and can be caused by various underlying conditions, while Multiple Myeloma primarily affects plasma cells in the bone marrow and is a form of cancer. Early diagnosis and appropriate treatment are crucial for managing both conditions and improving patient outcomes.
