What does an elevated kappa light chain mean?
A kappa free light chain test is a quick blood test that measures certain proteins in your blood. High levels of these proteins may mean you have a plasma cell disorder. A healthcare provider might order a kappa free light chain test if you have symptoms such as bone pain or fatigue.
What are kappa light chains?
Light chains are proteins produced by immune cells called plasma cells. Also called kappa and lambda light chains, they link together with other proteins (heavy chains) to form immunoglobulins (also known as antibodies) that target and neutralize specific threats to the body such as bacteria and viruses.
What are kappa light chains in myeloma?
Light chain myeloma can be classified as lambda or kappa light chain myeloma, depending on which type the cancerous cells produce. These light chains can build up in the kidneys, nerves, or other organs and cause serious complications. These two types of proteins have different structures.
What causes kappa light chain disease?
The underlying cause of LCDD is unknown. It is often associated with multiple myeloma. LCDD may progress to multiple myeloma, or it may be present with multiple myeloma when it is first diagnosed. The goal of treating LCDD is to slow the production of light chains and their damage to organs.
What vitamins help multiple myeloma?
Vitamin B-12 works together with folate to form red blood cells. A deficiency in B-12 can further decrease the bone marrow’s ability to make and maintain red blood cells in people with multiple myeloma.
Is vitamin C good for myeloma?
University of Iowa researchers in the Holden Comprehensive Cancer Center Multiple Myeloma Program recently found evidence that mega doses of vitamin C delivered intravenously may offer new hope to people diagnosed with multiple myeloma.
What is the difference between IgG Kappa and light chain myeloma?
In IgG kappa myeloma, the myeloma cells produce an immunoglobulin made from two IgG heavy chains bound to two kappa light chains. About 15% of patients have light chain myeloma. In this type of myeloma, the myeloma cells secrete only light chain protein and no heavy chains.
What is a kappa free light chain test?
A kappa free light chain test is a blood test that measures the levels of a certain type of protein in your blood. Your plasma cells (a type of white blood cell that fights infections and illnesses) make light chains. Light chains usually link up with other proteins called heavy chains.
What are the different types of light chain immunoglobulins?
The possible types of light chains are either kappa (κ) or lambda (λ). Myeloma cells make immunoglobulins. These immunoglobulins are made up of only one type of heavy chain (G, A, D, E, or M) and one type of light chain (kappa or lambda).
What is the relationship between lambda and kappa light chains?
In pathology. Individual B-cells in lymphoid tissue possess either kappa or lambda light chains, but never both together. Specific rearrangement of lambda light chain of immunoglobulins can lead to loss of some protein coding genes, which does not seem to be functionally relevant (while functionally relevant miR-650 can be overexpressed).
