What are the different types of amyloidosis?
This disorder is classified into four major forms: immunoglobulin light chain-derived (AL), reactive AA, dialysis-related (beta2M) and hereditary transthyretin (ATTR) type . Heart, kidney, gastrointestinal tract and peripheral nerves are commonly affected by amyloid deposition in systemic amyloidosis and histopathological demonstration of amyloid deposits on any of affected organs is the first step leading to the diagnosis of this disease. Immunohistochemical analysis of amyloid protein on tissue amyloid deposits is necessary to make classification of the disease and DNA testing is also useful in a hereditary form. Amyloidosis had been considered to be an incurable disease but during the past one decade several therapeutic approaches have been employed for the amyloidosis patients with diverse pathogenetic backgrounds: intravenous large dose of melphalan accompanied by autologous peripheral blood stem cell transplantation for AL amyloidosis and liver transplantation for hereditary ATTR type amyloidosis. As a result some amyloidosis patients have been rescued and are now enjoying their own social lives. It is likely that recent advance on the research of amyloidosis has changed the concept of this disease.

What is localized amyloidosis?
Localized amyloidosis (ALoc) There are many types of localized amyloidoses. Localized amyloid deposits in the airway (trachea or bronchus), eye, or urinary bladder are often caused by local production of immunoglobulin light chains, not originating in the bone marrow.
What causes AA amyloidosis?
AA amyloidosis is caused by a chronic infection or an inflammatory disease such as rheumatoid arthritis, familial Mediterranean fever (FMF), osteomyelitis, or granulomatous ileitis. Infection or inflammation causes elevation of an acute phase protein, SAA, a portion of which deposits as amyloid fibrils. Therefore, it is termed AA amyloidosis. AA amyloidosis usually begins as disease in the kidneys, but other organs can be affected. Medical or surgical treatment of the underlying chronic infection or inflammatory disease can slow down or stop the progression of this type of amyloidosis.
What is the name of the disorder in which a monoclonal immunoglobulin light chain is produced?
AL (immunoglobulin light chain) amyloidosis is an acquired plasma cell disorder in which a monoclonal immunoglobulin light chain is produced in the bone marrow and usually found in the blood or urine. AL amyloidosis occasionally occurs with multiple myeloma, lymphoma, or Waldenstorm’s macroglobulinemia. The amyloid fibrils in this type of amyloidosis are made up of immunoglobulin light chain proteins (kappa or lambda). Symptoms can occur in any organ of the body and include heart failure, protein in the urine or kidney failure, enlarged liver, neuropathy or enlarged tongue. Treatment with chemotherapy including high dose chemotherapy with stem cell transplantation, and other agents, can put the bone marrow disease in remission, leading to improvement in organ dysfunction and protect the target organs. This is one of the most common type of amyloidosis diagnosed in the United States.

What is the color of amyloid in a tissue biopsy?
A tissue biopsy involves the removal of a small sample of tissue to find evidence of amyloid deposits. Any kind of tissue or organ biopsy must be sent to a lab for microscopic examination, where the tissue is stained with a dye called “Congo-red stain.” After putting it under a microscope, amyloid protein is discovered if it turns an apple-green color, resulting in a diagnosis of amyloidosis. Possible areas for less invasive biopsies include:

Why do my fingers feel numb?
For example, patients may have carpal tunnel syndrome, where amyloid deposits in the wrist area can squeeze and irritate the nerve, causing tingling and numbness in the fingers and thumb. Deposits in the tongue may lead to a swollen and enlarged tongue, called “macroglossia.”.
What is the condition where the kidneys are swollen?
Amyloid deposits in the kidneys can affect how they filter toxins and proteins in the blood. This may result in a condition called nephrotic syndrome, where there is excess protein in the urine and the lower legs can become swollen (also called “edema”). Swelling can affect the belly, arms, and lungs as well.
