Systemic immunoglobulin light chain amyloidosis [PDF]

open access: yesNature Reviews Disease Primers, 2018
Systemic immunoglobulin light chain amyloidosis is a protein misfolding disease caused by the conversion of immunoglobulin light chains from their soluble functional states into highly organized amyloid fibrillar aggregates that lead to organ dysfunction.

Novel challenges in the management of immunoglobulin light chain amyloidosis: from the bench to the bedside

open access: yesExpert Review of Hematology, 2020
Introduction Immunoglobulin light chain (AL) amyloidosis is one of the most frequent systemic amyloidosis in Western countries. It is caused by a B-cell clone producing a misfolded light chain (LC) that deposits in organs.

Immunoglobulin light chain amyloidosis: 2024 update on diagnosis, prognosis, and treatment

American journal of hematology/oncology, 2023
Immunoglobulin light chain amyloidosis is a clonal, nonproliferative plasma cell disorder in which fragments of immunoglobulin light or heavy chain are deposited in tissues.

Immunohistochemical study of immunoglobulin light chain amyloidosis with antibodies to the immunoglobulin light chain variable region

Pathology International, 2006
To detect immunoglobulin (Ig) light chain amyloidosis (AL amyloidosis) in formalin‐fixed, paraffin‐embedded tissue sections by immunohistochemistry, polyclonal antibodies were generated against synthetic peptides corresponding to amino acids 1–19 of the Ig λ light chain V λ VI subgroup (anti‐V λ VI (1–19)) and the Ig κ light chain Vκ I subgroup (anti ...

Glycosylation of immunoglobulin light chains associated with amyloidosis

Amyloid: the International Journal of Experimental and Clinical Investigation: the Official Journal of the International Society of Amyloidosis, 2000
AL amyloidosis is a fatal disease caused by deposition of immunoglobulin light chains in a fibrillarforin (AL) in various organs. By searching the Kabat database of immunoglobulin sequences using the KabatMan software, we have shown that there is a preponderance of the consensus glycosylation sequon (AsnXxxSer/Thr) in the framework regions of amyloid ...

Treatment of immunoglobulin light chain amyloidosis

Current Hematologic Malignancy Reports, 2009
No therapy is uniformly effective in the management of immunoglobulin light chain amyloidosis (AL amyloidosis). Despite the common generalization, therapy is highly effective. Options available to patients with AL amyloidosis include high-dose therapy, but this is applicable to only about one fourth of patients.

Free Light Chains of Immunoglobulins in Amyloidosis

Acta Medica Scandinavica, 1979
ABSTRACT 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.

Immunoglobulin Light Chain Systemic Amyloidosis

2016
Immunoglobulin light chain amyloidosis (AL) is a rare, complex disease caused by misfolded free light chains produced by a usually small, indolent plasma cell clone. Effective treatments exist that can alter the natural history, provided that they are started before irreversible organ damage has occurred.

Systemic Immunoglobulin Light-Chain Amyloidosis

Clinical Lymphoma and Myeloma, 2006
Amyloidosis is a rare disease in which amyloid fibrils compromise organ function and lead to death. Systemic immunoglobulin light-chain amyloidosis, usually caused by free light chains (FLCs) made by clonal plasma cells, is the most frequent type. Hereditary and senile systemic amyloidosis are less frequent types.
