Renal Expression of Light Chain Binding Proteins.

Front Med (Lausanne) 2020 13;7:609582. Epub 2021 Jan 13.

Department of Medicine III, Division of Nephrology and Dialysis, Medical University of Vienna, Vienna, Austria.

Overproduction of human light chains (LCs) and immunoglobulins can result in various forms of renal disease such as cast nephropathy, monoclonal immunoglobulin deposition disease, LC proximal tubulopathy, AL amyloidosis, and crystal storing histiocytosis. This is caused by cellular uptake of LCs and overwhelmed intracellular transport and degradation in patients with high urine LC concentrations. LC kappa and lambda purification was evaluated by sodium dodecyl sulfate gel electrophoresis. Read More

Glomerular, Mesangial, and Tubular Cytoplasmic Fibrillary Inclusions in a Patient with Light-Chain Proximal Tubulopathy.

Nephron 2020 4;144(4):190-194. Epub 2020 Feb 4.

Department of Nephrology, The Mater Hospital, North Sydney, New South Wales, Australia.

Monoclonal immunoglobulin or free light chains, produced in the setting of plasma cell dyscrasias, are a common cause of kidney injury with a wide variety of disease patterns. Light-chain proximal tubulopathy is a rare form of this disease that is often difficult to diagnose due to its relatively indolent presentation, subtle light microscopic findings, and often negative immunofluorescence using routine laboratory techniques. We report a case of light-chain proximal tubulopathy with cytoplasmic fibrillary inclusions in tubular cells, glomerular endothelial cells, and mesangial cells, which were positive for κ light chains on immunostaining after pronase digestion.

Monoclonal Immunoglobulin Deposition Disease and Related Diseases.

J Nippon Med Sch 2019 ;86(1):2-9

Department of Analytic Human Pathology, Nippon Medical School.

Abnormal proliferation of plasma cells and some monoclonal B cells frequently cause the secretion of monoclonal immunoglobulins or immunoglobulin fragments into the serum, causing monoclonal gammopathy, which leads to various diseases including renal diseases. Therefore, monoclonal gammopathy is frequently associated with kidney diseases, including glomerular and tubulointerstitial diseases. Glomerular disease, with the deposition of monoclonal immunoglobulins or their components, includes monoclonal immunoglobulin deposition disease (MIDD), AL or AH amyloidosis, type I cryoglobulinemia, proliferative glomerulonephritis with monoclonal IgG deposits (PGNMID), immunotactoid glomerulopathy, and fibrillary glomerulonephritis.

d Departments of Pathology and Translational Pathobiology , Medicine, and Cell Biology and Anatomy, Louisiana State Health Sciences Center , Shreveport , LA , USA.

Mesangiopathies produced by glomerulopathic monoclonal immunoglobulin light chains (GLCs) acting on the glomerular mesangium produce two characteristic lesions: AL-amyloidosis (AL-Am) and light chain deposition disease (LCDD). In both cases, the pathology is centered in the mesangium, where initial and progressive damage occurs. In AL-Am the mesangial matrix is destroyed and replaced by amyloid fibrils and in LCDD, the mesangial matrix is increased and remodeled. Read More

Biomedica 2016 Dec 1;36(4):498-503. Epub 2016 Dec 1.

Unidad de Nefrología y Trasplante Renal, Hospital Pablo Tobón Uribe, Universidad de Antioquia, Medellín, Colombia.

Light chain-associated kidney compromise is frequent in patients with monoclonal gammopathies; it affects the glomeruli or the tubules, and its most common cause is multiple myeloma. It may develop after a kidney transplant due to recurrence of a preexisting multiple myeloma or it can be a de novo disease manifesting as graft dysfunction and proteinuria. A kidney biopsy is always necessary to confirm the diagnosis. Read More

Impaired Lysosomal Function Underlies Monoclonal Light Chain-Associated Renal Fanconi Syndrome.

J Am Soc Nephrol 2016 07 27;27(7):2049-61. Epub 2015 Nov 27.

Institute of Physiology, Zurich Center for Integrative Human Physiology, University of Zurich, Zurich, Switzerland; Division of Nephrology, UCL Medical School, Brussels, Belgium;

Monoclonal gammopathies are frequently complicated by kidney lesions that increase the disease morbidity and mortality. In particular, abnormal Ig free light chains (LCs) may accumulate within epithelial cells, causing proximal tubule (PT) dysfunction and renal Fanconi syndrome (RFS). To investigate the mechanisms linking LC accumulation and PT dysfunction, we used transgenic mice overexpressing human control or RFS-associated κLCs (RFS-κLCs) and primary cultures of mouse PT cells exposed to low doses of corresponding human κLCs (25 μg/ml).

Proximal tubulopathies associated with monoclonal light chains: the spectrum of clinicopathologic manifestations and molecular pathogenesis.

Arch Pathol Lab Med 2014 Oct;138(10):1365-80

From the Department of Pathology, Louisiana State University, Shreveport.

Context: Lesions associated with monoclonal light and heavy chains display a variety of glomerular, tubular interstitial, and vascular manifestations. While some of the entities are well recognized, including light and heavy chain deposition diseases, AL (light chain) and AH (heavy chain) amyloidosis, and light chain ("myeloma") cast nephropathy, other lesions centered on proximal tubules are much less accurately identified, properly diagnosed, and adequately understood in terms of pathogenesis and molecular mechanisms involved. These proximal tubule-centered lesions are typically associated with monoclonal light chains and have not been reported in patients with circulating monoclonal heavy chains. Read More

An animal model of glomerular light-chain-associated amyloidogenesis depicts the crucial role of lysosomes.

Kidney Int 2014 Oct 30;86(4):738-46. Epub 2014 Apr 30.

Department of Pathology, Louisiana State University Health, Shreveport, Louisiana, USA.

In vitro and ex vivo studies have elucidated the step-by-step process whereby some physicochemically abnormal light chains are processed by mesangial cells to form amyloid fibrils. Although crucial steps in the cascade of events have been determined, these findings have not been reproduced in vivo. This has led to some doubts as to the significance and clinical application of the information that has been deciphered. Read More

Adult Fanconi syndrome secondary to light chain gammopathy. Clinicopathologic heterogeneity and unusual features in 11 patients.

Medicine (Baltimore) 2000 May;79(3):135-54

Service de Néphrologie, Hôpital Tenon, Paris, France.

Fifty-seven cases of Ig light chain-associated Fanconi syndrome (FS) have been reported so far, mostly as isolated reports. The pioneering work by Maldonado and associates (35), who reviewed the first 17 cases in 1975, led to the unifying concept that patients with FS and Bence Jones proteinuria have a special form of plasma cell dyscrasia characterized by slow progression of the tumor and by prominent crystal formation in proximal tubule cells, in the absence of myeloma casts in the distal tubule. We carefully reappraised these characteristics in a series of 11 patients. Read More

Kappa light chain-associated Fanconi's syndrome: molecular analysis of monoclonal immunoglobulin light chains from patients with and without intracellular crystals.

Protein Eng 1999 Apr;12(4):363-9

INSERM U25, Laboratoire d'Immunologie Clinique, Hôpital Necker, 161 rue de Sèvres, F-75015 Paris, France.

Plasma cell dyscrasias may be responsible for Fanconi's syndrome, due to the toxicity of a free monoclonal kappa light chain toward kidney proximal tubules. Eight cases of Fanconi's syndrome were analyzed. We compared the structures of VkappaI variability subgroup V domains from five cases of Fanconi's syndrome and one myeloma without renal involvement.

Pathogenic potential of human monoclonal immunoglobulin light chains: relationship of in vitro aggregation to in vivo organ deposition.

Proc Natl Acad Sci U S A 1994 Apr;91(8):3034-8

Center for Mechanistic Biology and Biotechnology, Argonne National Laboratory, IL 60439-4833.

The deposition of certain Bence Jones proteins as tubular casts, basement membrane precipitates, or amyloid fibrils results in the human light-chain-associated renal and systemic diseases--myeloma (cast) nephropathy, light-chain deposition disease, and immunocyte-derived (primary or AL) amyloidosis. To determine if light-chain nephrotoxicity or amyloidogenicity is related to the propensity of these components to form high molecular weight aggregates under physiological conditions, we used a size-exclusion chromatographic system to study 40 different Bence Jones proteins. Each samples was tested over a wide range of protein concentration in three different buffers varying in pH, osmolality, and the presence or absence of low concentrations of urea. Read More

Primary amyloidosis associated with a novel heavy-chain fragment (AH amyloidosis).

Am J Hematol 1994 Feb;45(2):171-6

Department of Medicine, University of Tennessee Medical Center/Graduate School of Medicine, Knoxville 37920.

Primary or AL amyloidosis occurs in patients with monoclonal plasma cell-related disorders and is typically associated with the systemic deposition as amyloid fibrils of the light-chain portion of the immunoglobulin molecule. Recently, the discovery that heavy chains could be involved in amyloid formation led to the designation of this type of disease process as AH amyloidosis. We have now identified a second example of heavy chain-associated amyloidosis in a patient (MAD) who had a serum IgG monoclonal gammopathy and Bence Jones proteinuria. Read More

Nephrotoxic potential of Bence Jones proteins.

N Engl J Med 1991 Jun;324(26):1845-51

Department of Medicine, University of Tennessee Medical Center/Graduate School of Medicine, Knoxville.

Background: The renal manifestations of diseases associated with the production of monoclonal light chains--myeloma (cast) nephropathy, light-chain deposition disease, and amyloidosis AL--result from the deposition of certain Bence Jones proteins as tubular casts, basement-membrane precipitates, or fibrils, respectively. For unknown reasons, the severity of the renal manifestations of these diseases varies greatly from patient to patient. We employed an experimental in vivo model to determine the pathologic importance of various Bence Jones proteins. Read More
