Serum Free Light-chain Assay for the Diagnosis, Management, and Prognosis of Multiple Myeloma
In recent decades, new serum biomarkers have been developed for routine laboratory practice, such as assaying serum free light chains and more recently, assaying immunoglobulin heavy and light chain isotypes (Hevylite). In this work, we highlight the interest of new biomarkers (Hevylite Test) in the management of monoclonal gammopathies because of the technical advantages it confers and the se...
متن کاملSerum free light chain analysis and urine immunofixation electrophoresis in patients with multiple myeloma.
PURPOSE Retrospective studies have shown that immunoassays measuring free light chains (FLC) in serum are useful for diagnosis and monitoring of multiple myeloma. This study prospectively evaluates the use of FLC assays and, for the first time, investigates the relationship between serum FLC concentrations and the presence and detectability of Bence Jones (BJ) proteins in the urine. PATIENTS ...
متن کاملAnalysis of free serum light chains in patients suffering from multiple myeloma complicated by light-chain amyloidosis.
BACKGROUND AL amyloidosis is an acquired systemic disease in which a pathologic amorphous substance produced as a result of abnormal protein metabolism is deposited in the extracellular space of various tissues. OBJECTIVES The aim of the study was to investigate the relationship between the kappa and lambda serum free light chains (sFLCs) and the development of AL amyloidosis in patients suff...
متن کاملComparison of serum free light chain and urine electrophoresis for the detection of the light chain component of monoclonal immunoglobulins in light chain and intact immunoglobulin multiple myeloma.
Response criteria for multiple myeloma are based upon changes in monoclonal protein levels quantified using serum and/or urine protein electrophoresis. The latter lacks sensitivity at low monoclonal protein levels and since 2001, the serum free light chain test has been available and its clinical utility proven, yet guidelines have not recommended it as a replacement for urine assessment. Herei...
متن کاملIdentification of amyloidogenic light chains requires the combination of serum-free light chain assay with immunofixation of serum and urine.
BACKGROUND The diagnosis of systemic immunoglobulin light-chain (AL) amyloidosis requires demonstration of amyloid deposits in a tissue biopsy and amyloidogenic monoclonal light chains. The optimal strategy to identify the amyloidogenic clone has not been established. We prospectively assessed the diagnostic sensitivity of the serum free light chain (FLC) kappa/lambda ratio, a commercial serum ...
