The clinical significance of Bence Jones proteinuri

  1. The clinical significance of Bence Jones proteinuria The detection of monoclonal light chains in the urine by the Bence Jones heat test is a useful adjuvant to the diagnosis of myeloma and other related diseases. The test is particularly helpful when no serum spike is noted
  2. A Bence Jones protein is a monoclonal globulin protein or immunoglobulin light chain found in the urine, with a molecular weight of 22-24 kDa. Detection of Bence Jones protein may be suggestive of multiple myeloma or Waldenström's macroglobulinemia . Bence Jones proteins are particularly diagnostic of multiple myeloma in the context of target organ.
  3. Laboratory Tests for Bence-Jones Proteins. Bence-Jones proteins are not detectable via urine protein dipsticks. Detection of Bence-Jones proteinuria requires sophisticated tests such as urine protein electrophoresis, immunoelectrophoresis, and immunofixation electrophoresis. The screening test most commonly used is urine protein electrophoresis
  4. The Bence-Jones protein urine test is used most often to diagnose and check on multiple myeloma, a type of cancer. Or an abnormal Bence-Jones test result may mean you have a type of malignant lymphoma. These are cancers of the lymphatic system. Multiple myeloma is a type of blood cancer that affects plasma cells

Diagnosis of Multiple Myeloma: Bence-Jones Proteins

Bence Jones proteins are small proteins produced by plasma cells—small enough to pass through your kidneys, one of your body's main filtration systems. When your body has too many of these proteins, they easily pass from your bloodstream into your urine Bence Jones protein is found in the urine of people with certain diseases. One type of white blood cell, known as a B-lymphocyte, is part of the body's immune system, and is involved in the production of what are called immunoglobulins, otherwise known as antibodies.There are different lines of B-lymphocytes, each producing its own particular type of immunoglobulin which is involved in. The detection of Bence Jones protein, an important part of the investigation of suspected myeloma, is most commonly done by agarose or cellulose nitrate electrophoresis followed by immunofixation.

Bence-Jones Protein (Urine) - Health Encyclopedia

Bence Jones proteins are monoclonal immunoglobulin light chains found in urine (and plasma) of some patients with myeloma or other lymphoid malignancies. Because of their relatively small size, light chains are readily excreted into the urine. The presence of significant amounts of Bence Jones proteins in urine is indicative of malignant B cell. One part of the paraprotein is the light chain or Bence Jones protein, which the body gets rid of in the urine. Many people with myeloma have Bence Jones protein in their urine. These protein molecules can damage the kidneys as they pass through them from the blood to the urine. Read more about abnormal antibodies (paraproteins

  3. Monoclonal free light chain proteinuria (Bence Jones proteinuria) is seen in patients with light chain myeloma (where there is a monoclonal expression of the light chain without a coexisting heavy chain), in approximately 50% of those with IgG and IgA myeloma, and in some patients with other Lymphoproliferative disorders (e.g. macro­globulinaemia) and plasma cell dyscrasias (Amyloidosis)
  4. The Bence Jones protein is an antibody fragment (called a kappa or lambda light chain) not normally found in the urine. This protein is not detected during routine urinalysis screening for urine proteins. The presence of the Bence Jones protein is often suspected based on abnormalities in the electrophoresis of blood proteins

Proteinuria is a general term that describes any type of protein, including albumin, globulins, Bence Jones proteins, and others, in the urine. When proteinuria is detected, its potential clinical significance must be established. First it needs to be determined where the protein is coming from and whether it is prerenal, renal, or postrenal To the Editor: Detection of monoclonal immunoglobulin proteins is performed by protein electrophoresis, with the identity of any bands in serum and urine characterized by immunofixation electrophoresis (IFE) 1.In urine, evidence of abnormal production of monoclonal immunoglobulin is found as monoclonal κ and λ free light chains (FLC), also referred to as Bence Jones protein (BJP) Bence-Jones proteins are a part of regular antibodies called light chains. These proteins are not normally in urine. Sometimes, when your body makes too many antibodies, the level of light chains also rises. Bence-Jones proteins are small enough to be filtered out by the kidneys Proteinuria, a marker of kidney disease, is associated strongly with risk of adverse outcomes, including all-cause mortality.1-3 Life expectancy, a measure to estimate health status and disease burden at a population level, has not been reported for patients with different levels of proteinuria. This information could help policy makers recognize the health burden caused by proteinuria and.
