Immunoglobulin free light chains and solitary plasmacytoma of bone.
An abnormal serum immunoglobulin free light chain (FLC) ratio at diagnosis may identify risk of progression to myeloma in patients with solitary bone plasmacytoma (SBP). In the cohort of 116 patients, 43 have progressed to myeloma, with a median time to progression of 1.8 years. The FLC ratio was determined in all 116 patients on serum collected at time of diagnosis and was abnormal in 54 patie...
متن کاملEffects of free immunoglobulin light chains on viral myocarditis.
RATIONALE In recent work, we have demonstrated a crucial role of mast cells in the development of viral myocarditis. Viral infection could lead to increased synthesis of free immunoglobulin light chains (FLC) and our earlier work showed that FLC can trigger mast cell activation. OBJECTIVE We studied the possible involvement of FLC in the pathogenesis of viral myocarditis, and therapeutic effe...

but the active/latent isoform proportions were similar (Fig. 1A). Platelet aggregation during clotting (6) may have caused these differences. MMP expression was lower in K 2 E plasma than in LH plasma [14 (3) vs 25 (4) g/L; P Ͻ0.05; Fig. 1A, lane 4 vs lane 5]. The concentrations of MMP-9 forms decreased significantly with increasing amounts of K 2 E during PB collection, whereas MMP-2 was incr...
متن کاملElicitation of allergic asthma by immunoglobulin free light chains.
The observation that only 50% of patients with adult asthma manifest atopy indicates that other inflammatory mechanisms are likely involved in producing the characteristic features of this disorder; namely reversible airway obstruction, hyperresponsiveness, and pulmonary inflammation. Our recent discovery that antigen-specific Ig free light chains (LCs) mediate hypersensitivity-like responses s...
متن کاملSerum 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...
