kidney pathologies can occur, including light chain cast nephropathy, monoclonal immunoglobulin deposition disease, light chain amyloidosis, light chain proximal tubulopathy, and tubulointerstitial.. cells.3 When light chains saturate the metabolic capacity of the proximal tubules, nonabsorbed light chains appear in the urine as Bence Jones protein.4 Absorbed light chains may inhibit a variety of cellular functions, including organic ion transport, gluconeogenesis, and formation of ammonia.5 Light-chain-induced nephropathy may b

Light chain cast nephropathy (LCCN) is the leading cause of acute renal failure in patients with multiple myeloma and is currently recognized as a myeloma defining event Journal of Nepal Medical Association (2012-12-01) . Lambda Light Chain Myeloma with Oliguric Cast Nephropathy and Remission with Bortezomib, Doxorubicin and Dexamethason Light chain cast nephropathy (LCCN), not to be confused with light chain deposition disease (LCDD), is also known as myeloma cast nephropathy or myeloma kidney; and is one of the many renal complications of multiple myeloma Light chain cast nephropathy is the most common renal lesion associated with multiple myeloma and more than 90% of patients with cast nephropathy have multiple myeloma. Light chain cast nephropathy is not considered a monoclonal gammopathy of renal significance since the presence of cast nephropathy is considered a myeloma-defining event

Light chain cast nephropathy and acute renal failure associated with rifampin therapy: Renal disease akin to myeloma kidney OvedSofferM.D. a Victor H.NassarM.D.a Wallace G.CampbellJr Patients with multiple myeloma overproduce monoclonal Ig light chains (Bence Jones proteins); these light chains are filtered by glomeruli, are nephrotoxic, and, in their various forms (free, tubular casts, amyloid), can damage virtually all areas of the kidney parenchyma

Tubular lesions include the classic Fanconi syndrome, light-chain proximal tubulopathy, interstitial fibrosis, and cast nephropathy. These paraproteinemic renal diseases are distinct in their pathogenesis as well as their urinary and kidney biopsy findings These different patterns of paraprotein-mediated disease tend to be mediated preferentially by either kappa or lambda light chains: In cast nephropathy, lambda light chain is the most common. In light chain deposition disease (LCDD), kappa light chain is the most common. In AL amyloidosis, lambda light chain is the most common Lambda light chain nephropathy was characterized by linear lambda glomerular basement membrane and tubular basement membrane immunostaining. Manifestations of glomerular dysfunction dominated the clinical presentation of light chain nephropathy, and most patients did not have typical features of multiple myeloma Immunoglobulin A (IgA) nephropathy and IgA lambda myeloma with mesangial proliferative glomerulonephritis (GN) have been reported [ 1 ]. An interaction between mesangial cells and IgA as well as IgG immune complexes provides a possible mechanism for glomerular injury in IgA nephropathy [ 2 ] Bence Jones nephropathy Also called myeloma cast nephropathy or myeloma kidney Occurs in 30 - 40% at autopsy Proteinuria consisting of light chains, which are normally filtered by glomeruli, reabsorbed and metabolized by proximal tubular cell

Light Chain Cast Nephropathy: Practical Considerations in

Kappa/Lambda Light Chains in Multiple Myeloma. Multiple myeloma is a blood cancer of white blood cells called plasma cells. Plasma cells come from the bone marrow and they produce antibodies (also called immunoglobulins) that fight wide variety of infections. In myeloma, one of these antibodies grows out of control in the bone marrow, crowding. Light chain cast nephropathy (LCCN) is the most common renal disease caused by multiple myeloma (MM). In addition to ordinary light chain protein casts, there are a few rare casts with unique shapes, including light chain amyloid casts (LCAC) and light chain crystal casts (LCCC). Here, we report two patients. Patient 1 is a 72-year-old man who was clinically diagnosed with MM and acute kidney. Our patient's recovery from AKI caused by myeloma cast nephropathy shows (a) HDF with PEPA dialyzer is a safe and effective technique for lambda light chains removal, which present a molecular weight of 45.000 Da; (b) the present result will be applicable to the removal of the smaller kappa light chains (m.w. 22.000 Da); (c) HDF with PEPA. Deposition of light chains in the heart muscle is seen in about 80% of patients with this disease, and symptoms related to the heart muscle damage can be more prominent than symptoms from the kidney. Many people who develop kidney disease first may not notice anything, but have changes in their urine such as losing protein, blood, sugar, or acid

The diagnosis of lambda light chain cast nephropathy was made on the fourth allograft biopsy on POD 81. With no recovery of renal function, the patient underwent transplant nephrectomy on POD 83, with planned initiation of melphalan and prednisone But on the left you can see that this particular patient had lambda light chain cast nephropathy, indicating that it's a monoclonal protein problem.

Light chain cast nephropathy is the most frequent form of renal disease in plasma cell neoplasm showing precipitation of monoclonal immunoglobulin light chains in the lumen of the distal tubules.

Discussion This case highlights an unusual presentation of WM with the presence of kappa light chain cast nephropathy and tubulopathy. No other glomerulopathy was seen on renal biopsy. The patient did not have any cryoglobulins in the blood The presence of only a light chain monoclonal protein is seen in ~20% of multiple myeloma cases and the condition is known as light chain myeloma. Light chain myeloma patients secrete either low molecular weight kappa or lambda chains which get filtered at glomerulus, reabsorbed and catabolized in renal tubules light chain proteinuria. Because the indicator on the dipsticks for urinary protein is designed to detect albumin, a 31 reading is incompatible with considerable light chain proteinuria. Thus, despite the light microscopic findings of only Bence-Jones cast nephropathy, it did not come as a surprise to find light chain deposit disease (b
