Free light chains of immunoglobulins in amyloidosis. 1979

J Sølling, and K Sølling

Monomeric (M) and dimeric (D) forms of free light chains in serum have been measured by a sensitive radioimmunoassay in eight patients with amyloidosis without monoclonal proteins. Significantly elevated concentrations of D lambda chains were demonstrated in two of four patients with localized amyloidosis. The two patients had a significantly increased D/M ratio of both kappa and lambda chains. One patient had localized amyloidosis and normal concentration of monomeric and dimeric light chains had an abnormal fragment of light chains. A low kappa/lambda ratio was found in patients with localized amyloidosis. Four patients with secondary amyloidosis and renal insufficiency had increased amounts of free light chains. The concentration of light chains and the D/M ratio in this group corresponded to the impairment of renal function.

D007147	Immunoglobulin Light Chains	Polypeptide chains, consisting of 211 to 217 amino acid residues and having a molecular weight of approximately 22 kDa. There are two major types of light chains, kappa and lambda. Two Ig light chains and two Ig heavy chains (IMMUNOGLOBULIN HEAVY CHAINS) make one immunoglobulin molecule.

D011863	Radioimmunoassay	Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.

D000686	Amyloidosis	A group of sporadic, familial and/or inherited, degenerative, and infectious disease processes, linked by the common theme of abnormal protein folding and deposition of AMYLOID. As the amyloid deposits enlarge they displace normal tissue structures, causing disruption of function. Various signs and symptoms depend on the location and size of the deposits.	Amyloidoses
D001172	Arthritis, Rheumatoid	A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated.	Rheumatoid Arthritis
