Immunoglobulin Free Light Chains Are Increased in Hypersensitivity Pneumonitis and Idiopathic Pulmonary Fibrosis
BACKGROUND Idiopathic pulmonary fibrosis (IPF), a devastating lung disorder of unknown aetiology, and chronic hypersensitivity pneumonitis (HP), a disease provoked by an immunopathologic reaction to inhaled antigens, are two common interstitial lung diseases with uncertain pathogenic mechanisms. Previously, we have shown in other upper and lower airway diseases that immunoglobulin free light ch...
متن کاملImmunoglobulin 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 کاملFree immunoglobulin light chains in connective tissue diseases.
The basic immunoglobulin subunit consists of two heavy and two light chains held together by covalent disulphide bonds. In most cases of myeloma and Waldenstrom's disease there is an excess synthesis of light over heavy chains, resulting in Bence Jones proteinaemia and proteinuria. Furthermore, in some cases ("light chain disease"), there is absence of detectable heavy chain synthesis, and the ...
