Polyclonal free light chains: a biomarker of inflammatory disease or treatment target?
Free light chains are proteins produced by B lymphocytes during the process of antibody synthesis. Their production, as a reflection of B cell activation, can give insight into the activity of the adaptive immune system. In recent years, an automated immunoassay that provides quantitative measurement of free light chains in the serum has been developed. This assay has not only revolutionised th...
متن کاملPolyclonal light chains in cerebrovascular disease
Altered membrane permeability is a hallmark of inflammation and ischemia with systemic spreading. Renal dysfunction is a risk factor for cardiovascular, cerebrovascular, and metabolic diseases. The aim of the present study was to assess proteinuria and urinary polyclonal light chains in acute stroke and chronic cerebrovascular disease compared with other neurologic diseases. Our results showed ...
متن کاملQuantitative assessment of serum and urinary polyclonal free light chains in patients with chronic kidney disease.
BACKGROUND AND OBJECTIVES Monoclonal free light chains (FLC) frequently cause kidney disease in patients with plasma cell dyscrasias. Polyclonal FLC, however, have not been assessed in patients with chronic kidney disease (CKD) yet could potentially play an important pathologic role. This study describes for the first time polyclonal FLC in patients with CKD. DESIGN, SETTING, PARTICIPANTS, & ...
متن کاملMonoclonal and polyclonal serum free light chains and clinical outcome in chronic lymphocytic leukemia.
Free light chains (FLCs) are the most commonly detected paraproteins in chronic lymphocytic leukemia (CLL). We examined the types of FLC abnormalities and prognostic utility of the FLC assay compared with standard prognostic biomarkers in a prospective cohort of 339 patients with newly diagnosed CLL. Three types of FLC abnormalities were identified: monoclonal elevated FLC (elevated κ and/or λ ...
متن کاملMonoclonal vs polyclonal free light chain assays.
Am J Clin Pathol 2009;131:897-903 901 © American Society for Clinical Pathology relative to Freelite (Figure 1). Both patients had negative results for urine BJPs, further undermining the validity of the ELISA assay results. It is possible that the monoclonal antibodies are cross-reacting with the reported IgG λ and IgA λ monoclonal intact immunoglobulins in these patients, leading to falsely r...
