Monoclonal 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 کاملPrognostic Significance of Serum Free Light Chains in Chronic Lymphocytic Leukemia
Background. Serum free light chains (sFLC), the most commonly detected paraprotein in CLL, were recently proposed as useful tools for the prognostication of CLL patients. Objective. To investigate the prognostic implication of sFLC and the summated FLC-kappa plus FLC-lambda in a CLL patients' series. Patients and Methods. We studied 143 CLL patients of which 18 were symptomatic and needed treat...
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 کاملThe clinical application of monoclonal antibodies in chronic lymphocytic leukemia.
Chronic lymphocytic leukemia (CLL) represents the most prevalent adult leukemia. Treatment with chemotherapy over the past 3 decades has been palliative. The introduction of therapeutic antibodies has increased the number of treatment options for this disease. Despite this increase, our true understanding of the mechanism of action of antibody therapy in CLL remains limited. Rituximab, a CD20 a...
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...
