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.
Diseases in which there is a familial pattern of AMYLOIDOSIS.
A fibrous protein complex that consists of proteins folded into a specific cross beta-pleated sheet structure. This fibrillar structure has been found as an alternative folding pattern for a variety of functional proteins. Deposits of amyloid in the form of AMYLOID PLAQUES are associated with a variety of degenerative diseases. The amyloid structure has also been found in a number of functional proteins that are unrelated to disease.
An ACUTE PHASE REACTION protein present in low concentrations in normal sera, but found at higher concentrations in sera of older persons and in patients with AMYLOIDOSIS. It is the circulating precusor of amyloid A protein, which is found deposited in AA type AMYLOID FIBRILS.

Impaired lysosomal processing of beta2-microglobulin by infiltrating macrophages in dialysis amyloidosis. (1/1787)

BACKGROUND: Macrophages may participate in amyloid fibril formation by processing the protein precursor. Although this theory seems to apply for amyloidosis, in which proteolytic cleavage is a prerequisite for amyloid fibril formation, it has not been demonstrated for beta2-microglobulin (beta2m) amyloidosis. We aimed to establish the role played by macrophages in beta2m amyloidosis. METHODS: We used a double immunogold electron microscopy technique, including mouse antihuman CD68, rabbit antihuman beta2m, amyloid P component, and lysosome-associated membrane protein (LAMP-1) antibodies. Differential density labeling studies of beta2m and amyloid P component were performed extra- and intracellularly to assess protein processing by macrophages. RESULTS: The cells surrounding amyloid fibrils were found to be mostly CD68 positive, suggesting that they were of monocyte-macrophage lineage. Intracellular accumulation of amyloid fibrils was also observed; these fibrils were constantly surrounded by LAMP-1-linked gold particles, demonstrating that intracellular beta2m was almost exclusively lysosomal. The rough-surface endoplasmic reticulum was not labeled by beta2m antibody, suggesting that there was no active synthesis of beta2m by the cells. As a marker of endocytosis, protruded cytoplasmic processes in close relation with the intracellular accumulations of beta2m amyloid fibrils were observed. No difference in density labeling (extracellular vs. intracellular) was observed for beta2m, whereas intracellular P component labeling was significantly decreased. CONCLUSIONS: All of these data are strongly suggestive of phagocytosis and not synthesis of amyloid fibrils by macrophages. Further, they demonstrate an impaired lysosomal processing specific for beta2m, as other compounds of the amyloid fibrils (P component) are significantly cleared.  (+info)

The heparin/heparan sulfate-binding site on apo-serum amyloid A. Implications for the therapeutic intervention of amyloidosis. (2/1787)

Serum amyloid A isoforms, apoSAA1 and apoSAA2, are apolipoproteins of unknown function that become major components of high density lipoprotein (HDL) during the acute phase of an inflammatory response. ApoSAA is also the precursor of inflammation-associated amyloid, and there is strong evidence that the formation of inflammation-associated and other types of amyloid is promoted by heparan sulfate (HS). Data presented herein demonstrate that both mouse and human apoSAA contain binding sites that are specific for heparin and HS, with no binding for the other major glycosaminoglycans detected. Cyanogen bromide-generated peptides of mouse apoSAA1 and apoSAA2 were screened for heparin binding activity. Two peptides, an apoSAA1-derived 80-mer (residues 24-103) and a smaller carboxyl-terminal 27-mer peptide of apoSAA2 (residues 77-103), were retained by a heparin column. A synthetic peptide corresponding to the CNBr-generated 27-mer also bound heparin, and by substituting or deleting one or more of its six basic residues (Arg-83, His-84, Arg-86, Lys-89, Arg-95, and Lys-102), their relative importance for heparin and HS binding was determined. The Lys-102 residue appeared to be required only for HS binding. The residues Arg-86, Lys-89, Arg-95, and Lys-102 are phylogenetically conserved suggesting that the heparin/HS binding activity may be an important aspect of the function of apoSAA. HS linked by its carboxyl groups to an Affi-Gel column or treated with carbodiimide to block its carboxyl groups lost the ability to bind apoSAA. HDL-apoSAA did not bind to heparin; however, it did bind to HS, an interaction to which apoA-I contributed. Results from binding experiments with Congo Red-Sepharose 4B columns support the conclusions of a recent structural study which found that heparin binding domains have a common spatial distance of about 20 A between their two outer basic residues. Our present work provides direct evidence that apoSAA can associate with HS (and heparin) and that the occupation of its binding site by HS, and HS analogs, likely caused the previously reported increase in amyloidogenic conformation (beta-sheet) of apoSAA2 (McCubbin, W. D., Kay, C. M., Narindrasorasak, S., and Kisilevsky, R. (1988) Biochem. J. 256, 775-783) and their amyloid-suppressing effects in vivo (Kisilevsky, R., Lemieux, L. J., Fraser, P. E., Kong, X., Hultin, P. G., and Szarek, W. A. (1995) Nat. Med. 1, 143-147), respectively.  (+info)

Colchicine inhibition of the first phase of amyloid synthesis in experimental animals. (3/1787)

Colchicine was found to inhibit the first phase of casein-induced synthesis of murine amyloid. When mice were treated with colchicine during the first 7 days of an amyloid induction regimen or when colchicine was given to the donor mice in a transfer model, the amyloidogenic stimulus of casein was blocked completely. Amyloid synthesis was however, not interrupted by the administration of colchicine during the last 7 days of the casein regimen nor by colchicine treatment of recipient mice in a transfer model.  (+info)

Cells with clonal light chains are present in peripheral blood at diagnosis and in apheretic stem cell harvests of primary amyloidosis. (4/1787)

In primary systemic amyloidosis, small numbers of bone marrow plasma cells secrete monoclonal light chains that form extracellular fibrils (amyloid) in various organs. Evidence limited to a few cases suggests that rare clonal elements can also be found in the peripheral blood (PB), and this may be relevant in PB stem cell autotransplantation. Since up to 40% of amyloid clones do not synthesize heavy chains, in order to detect tumor cells with high specificity and sensitivity we developed a seminested allele-specific oligonucleotide polymerase chain reaction for tumor light chains. Clone-related sequences were detected in DNA and/or cDNA from the PB cells of eight of 10 patients at diagnosis and from apheretic collections of three of four cases undergoing PB progenitor autotransplantation. Since there are experimental data suggesting that circulating tumor cells may be involved in the growth of the amyloidogenic clone and may be chemoresistant, these findings are relevant to the use of leukapheresis purging strategies for PB progenitor autotransplantation in amyloidosis.  (+info)

The degrees of plasma cell clonality and marrow infiltration adversely influence the prognosis of AL amyloidosis patients. (5/1787)

BACKGROUND AND OBJECTIVE: Primary amyloidosis is a lethal form of plasma cell (PC) dyscrasia characterized by deposits of monoclonal immunoglobulin light chains that cause organ dysfunction. In contrast to multiple myeloma, the amyloid clone is typically indolent and of small size, and marrow PC clonality is not always apparent. This is generally investigated by analyzing the light chain isotype ratio in bone marrow PC. We investigated whether the degree of PC infiltration (PC%) and clonality (PC isotype ratio) affected survival in 56 consecutive patients with primary amyloidosis. DESIGN AND METHODS: PC% was determined by morphologic examination. Immunofluorescence microscopy was used to determine the PC light chain isotype ratio. Statistical analysis was carried out using Cox regression models. RESULTS: The degrees of PC clonality and infiltration were inversely correlated with survival (PC isotype ratio, p = 0.001; PC%, p = 0.008). The two variables were weakly correlated (p = 0.02; r = 0.3). Bone marrow PC isotype ratio demonstrated a powerful independent prognostic value at multivariate analysis when analyzed together with congestive heart failure (the major known negative prognostic factor) and PC%. k/l ratio cut-off values of 0.2 (l patients, p = 0.022) and 16 (k patients, p = 0.03) discriminated two groups with a similar number of patients and significantly different survivals. INTERPRETATION AND CONCLUSIONS: PC clonality and marrow infiltration are important parameters that influence prognosis, presumably because they reflect the amount of pathogenic light chain synthesis.  (+info)

Organ-specific (localized) synthesis of Ig light chain amyloid. (6/1787)

Ig amyloidosis is usually a systemic disease with multisystem involvement. However, in a significant number of cases amyloid deposition is limited to one specific organ. It has not been determined if the Ig light chain (LC) amyloid precursor protein in localized amyloidosis is synthesized by circulating plasma cells with targeting of the amyloid fibril-forming process to one specific organ, or whether the synthesis of Ig LC and fibril formation occurs entirely as a localized process. In the present study local synthesis of an amyloid fibril precursor LC was investigated. Amyloid fibrils were isolated from a ureter that was obstructed by extensive infiltration of the wall with amyloid. Amino acid sequence analysis of the isolated fibril subunit protein proved it to be derived from a lambdaII Ig LC. Plasma cells within the lesion stained positively with labeled anti-lambda Ab and by in situ hybridization using an oligonucleotide probe specific for lambda-LC mRNA. RT-PCR of mRNA extracted from the tumor and direct DNA sequencing gave the nucleotide sequence coding specifically for the lambdaII amyloid subunit protein, thus confirming local synthesis of the LC protein.  (+info)

Histological characteristics of sternoclavicular beta 2-microglobulin amyloidosis and clues for its histogenesis. (7/1787)

BACKGROUND: The pathogenesis of beta 2-microglobulin amyloidosis (A beta 2m) has yet to be fully elucidated. METHODS: We describe the distribution and extent of A beta 2m deposition and macrophagic infiltration in cartilage, capsule, and synovium of sternoclavicular joints obtained postmortem from 54 patients after 3 to 244 (median 46) months of dialysis. Twenty-four nonuremic patients served as a control group. The diagnosis of amyloidosis (A) rested on a positive Congo Red staining (typical birefringence) and that of A beta 2m on positive immunostaining of the A deposits with a monoclonal anti-beta 2m antibody. The size of A deposits was measured. RESULTS: A beta 2m was detected in 32 (59%), and non-beta 2m amyloid (Anon beta 2m) was detected in an additional 8 (15%) of the 54 dialyzed patients. A beta 2m deposits were present in the cartilage of all A beta 2m (+) patients (100%). They were localized solely in the cartilage in 27% of the cases, either as a thin patchy layer or as a continuous thicker layer (identified as stage I). A beta 2m was additionally present in the capsule and/or synovium without macrophages in 27% of the cases (identified as stage II). The correlation between the size of cartilaginous deposits and dialysis duration (P = 0.02) as well as with the prevalence (P = 0.03) and size of capsular deposits (P = 0.02) suggests that stage II is a later stage of A deposition. Clusters of macrophages were detected around capsular and synovial amyloid deposits in 46% of the cases (identified as stage III). The longer duration of dialysis in those with stage III as well as the relationship between the size of the A beta 2m deposits and the prevalence of macrophagic infiltration suggests that stage III is the last stage of A beta 2m deposition. Marginal bone erosions were observed in 9 out of 12 patients with stage III deposits. Their size was correlated with that of cartilaginous deposits (P = 0.01). Among the 24 control patients, Anon beta 2m was detected in 12 patients (cartilage 100%, capsule 8%, synovium 30%). CONCLUSIONS: The earliest stage of A beta 2m deposition occurs in the cartilage. A beta 2m subsequently extends to capsule and synovium. These two first stages do not require macrophage infiltration. Macrophages are eventually recruited around larger synovial or capsular deposits in the final stage. Marginal bone erosions develop in this late stage.  (+info)

Morphological, histochemical, immunohistochemical, and ultrastructural characterization of tumors and dysplastic and non-neoplastic lesions arising in BK virus/tat transgenic mice. (8/1787)

To study the role in AIDS pathogenesis of the human immunodeficiency virus type 1 (HIV-1) Tat protein, a transactivator of viral and cellular genes, we generated transgenic mice with a recombinant DNA containing BK virus (BKV) early region and the HIV-1 tat gene, directed by its own promoter-enhancer. DNA hybridization revealed that the transgene is stably maintained in all organs of transgenic mice as a tandem insertion in a number of copies ranging from 5 to 20 per cell. In addition, tat and BKV RNA were expressed in all tissues. Transgenic mice developed three types of lesions: 1) tumors, 2) hyperplastic and dysplastic lesions, and 3) non-neoplastic lesions. Tumors of different histotypes, such as lymphomas, adenocarcinomas of skin glands, leiomyosarcomas, skin squamous cell carcinomas, hepatomas, hepatocarcinomas, and cavernous liver hemangiomas, developed in 29% of transgenic animals. The majority of tumors were malignant, invasive, and producing metastases. Conversely, tumors of only two histotypes (lymphomas and adenocarcinomas of skin glands) appeared in control mice. Hyperplastic and dysplastic lesions were more frequent in transgenic than in control mice and involved the skin or its adnexes, the liver and the rectum, indicating multiple targets for the activity of the transgene. Pyelonephritis, frequently complicated with hydronephrosis, inflammatory eye lesions, and amyloid depositions represented the most frequent non-neoplastic lesions detected in transgenic mice. Many of the pathological findings observed in this animal model are comparable to similar lesions appearing in AIDS patients, suggesting a relevant role for Tat in the pathogenesis of such lesions during the course of AIDS.  (+info)

AL Amyloidosis is known to be a systemic disease affecting multiple organs and tissue while its rare that patients present with gastrointestinal symptoms at first and later develop multiple-organ dysfuction. Clinical signs are not specific and the diagnosis is rarely given before performing immunofixation and endoscopy with multiple biopsies. We would like to emphasize the value of precise diagnostic process of AL amyloidosis. In this case report, we describe a 56-year-old man who presented with recurrent periumbilical pain for 4 months and gradually worsened over a month. After a series of tests, he was finally diagnosed with primary systemic AL amyloidosis. He was treated with a chemotherapy regimen (Melphalan, dexamethasone and thalidomide) achieving a good clinical response. On account of the high misdiagnosis rate, establishing the most precise diagnosis in first time with typing amyloidogenic protein becomes increasingly vital. Although the presenting feature is usually nonspecific, AL

Immunoglobulin light chain amyloidosis (AL) is a plasma cell dyscrasia characterized by deposition of amyloid fibrils in various organs and tissues, derived from monoclonal light chains, leading to organ dysfunction.1-3 High-dose melphalan with autologous stem cell transplant (HDM/SCT) is an effective treatment with high complete hematologic response rates (CR) and is capable of producing durable remissions and prolonged overall survival.4-6 Only selected patients are eligible to receive HDM/SCT, and treatment-related mortality is in the range of 5-15%. More effective and widely applicable treatment modalities in AL amyloidosis are, therefore, needed.. Clinical trials of alternate treatment options have tested non-transplant melphalan-based strategies and novel therapeutics such as lenalidomide and bortezomib. Oral melphalan and dexamethasone (M-Dex) is a standard regimen for patients not eligible to receive HDM/SCT; reported complete response rates range from 13% to 33% and median overall ...

AA amyloidosis is a form of amyloidosis, a disease characterized by the abnormal deposition of fibers of insoluble protein in the extracellular space of various tissues and organs. In AA amyloidosis, the deposited protein is serum amyloid A protein (SAA), an acute-phase protein which is normally soluble and whose plasma concentration is highest during inflammation. AA amyloidosis is a complication of a number of inflammatory diseases and infections, although only a small portion of patients with these conditions will go on to develop AA amyloidosis. A natural history study of AA amyloidosis patients published in the New England Journal of Medicine reported a number of conditions associated with AA amyloidosis. The most common presentation of AA amyloidosis is renal in nature, including proteinuria, nephrotic syndrome and progressive development of renal insufficiency leading to End Stage Renal Disease (ESRD) and need for renal replacement therapy (e.g. dialysis or renal transplantation). ...
Systemic amyloidosis can be classified as follows: (1) primary systemic amyloidosis (PSA), usually with no evidence of preceding or coexisting disease, paraproteinemia, or plasma-cell dyscrasia; (2) amyloidosis associated with multiple myeloma; or (3) secondary systemic amyloidosis with evidence of coexisting previous chronic inflammatory or ...
Amyloidosis is a disorder caused by misfolding of autologous protein and its extracellular deposition as fibrils, resulting in vital organ dysfunction and eventually death. Pulmonary amyloidosis may be localised or part of systemic amyloidosis.. Pulmonary interstitial amyloidosis is symptomatic only if the amyloid deposits severely affect gas exchange alveolar structure, thus resulting in serious respiratory impairment. Localised parenchymal involvement may be present as nodular amyloidosis or as amyloid deposits associated with localised lymphomas. Finally, tracheobronchial amyloidosis, which is usually not associated with evident clonal proliferation, may result in airway stenosis.. Because the treatment options for amyloidosis are dependent on the fibril protein type, the workup of all new cases should include accurate determination of the amyloid protein. Most cases are asymptomatic and need only a careful follow-up. Diffuse alveolar-septal amyloidosis is treated according to the underlying ...
Amyloidosis is a disease in which amyloid, an unusual protein that normally isnt present in the body, accumulates in various tissues.. Many forms of amyloidosis exist. In primary amyloidosis, the cause isnt known. However, the disease is associated with abnormalities of plasma cells, as is multiple myeloma, which may also be associated with amyloidosis. In secondary amyloidosis, the amyloidosis is secondary to another disease such as tuberculosis, infections of the bone, rheumatoid arthritis, familial Mediterranean fever, or granulomatous ileitis. A third form, hereditary amyloidosis, affects nerves and certain organs; it has been noted in people from Portugal, Sweden, Japan, and many other countries.. Another form of amyloidosis is associated with normal aging and particularly affects the heart. What causes amyloid to build up excessively usually isnt known. However, amyloidosis can be a response to various diseases that cause persistent infection or inflammation. Yet another form of ...
Amyloidosis is the extracellular deposition of insoluble amyloid fibrilprotein in any tissue or organ.[1] The most common subtypes of the disease are AL amyloidosis and AA reactive amyloidosis.[1] AL amyloidosis is a systemic disease caused by immunoglobulin light chain fragments, while AA amyloidosis is a potential complication of recurrent inflammation leading to the production of serum amyloid A, an acute phase reactant.[2] Pulmonary amyloidosis is a localized form of amyloid deposition that is confined to the lung parenchyma.[

Demographics: Patients can be of almost any age, from childhood to elderly, depending on the underlying cause. Primary amyloidosis shows a male predominance.. Cardinal Findings: In primary amyloidosis, the most commonly involved organs are the kidney, heart, liver, and skin; skeletal muscle and the tongue may also be affected. Peripheral neuropathies are seen, but the central nervous system (CNS) is generally not involved. Secondary amyloidosis most commonly presents with nephrotic syndrome or gastrointestinal (GI) bleeding. Macroglossia is not seen with secondary amyloidosis. The initial finding in hemodialysis associated amyloid is often CTS.. Uncommon Manifestations: In primary amyloidosis, amyloid deposits may be seen in the synovium and occasionally in the synovial fluid.. Diagnostic Tests: Biopsies of affected tissues are usually required. The tissues are stained with Congo red and viewed under polarized light. Kidney and peripheral nerve biopsy specimens can be useful if there are known ...
Nodular pulmonary amyloidosis (NPA) is an uncommon pathology of insoluble protein depositing in pulmonary parenchyma. This localized pulmonary form of amyloidosis is most often found to contain combinations of kappa and lambda immunoglobulin light chain and immunoglobulin heavy chain proteins with a polyclonal lymphoplasmacystic infiltrate. Herein we present two cases of NPA of the rarely reported monoclonal (light-chain restricted) form with review of the literature and discussion of the clinical, radiographic, and histologic features of NPA.
The UK ATTR Amyloidosis Patients Association (UKATPA) was founded in 2017 by a group of UK patients with transthyretin (TTR)-type systemic amyloidosis (ATTR), supported by the consultant physicians of the UK NHS National Amyloidosis Centre.. In recent years there have been major advances in the field of ATTR amyloidosis. The processes responsible for formation of TTR amyloid have been elucidated for the first time and intense activity in drug development promises the early advent of potentially effective prophylactic and disease modifying new medicines. Hereditary ATTR amyloidosis, caused by mutations in the TTR gene, is the most common form of hereditary amyloidosis but is nonetheless very rare. However, crucially, there is now compelling evidence that acquired ATTR amyloidosis, caused by normal wild type TTR, is far more common than was previously believed.. In this exciting environment of change and optimism, our members decided to found a UK patient group dedicated to the interests of ...

TY - JOUR. T1 - Hereditary systemic immunoglobulin light-chain amyloidosis. AU - Benson, Merrill. AU - Liepnieks, Juris J.. AU - Kluve-Beckerman, Barbara. PY - 2015. Y1 - 2015. N2 - Several members of a family died from renal failure as a result of systemic amyloidosis. Extensive studies to detect previously documented gene mutations associated with amyloidosis failed to identify a causative factor. In search of the genetic basis for this syndrome, amyloid fibrils were isolated from renal tissue of a member of the kin who died while on renal dialysis. Amino acid sequencing of isolated amyloid protein identified sequences compatible with the constant region of the immunoglobulin κ light-chain. Isolation and characterization of κ light-chain protein from serum of an affected member of the kindred revealed mutation in the constant region of kκlight-chain, with cysteine replacing serine at amino acid residue 131. This mutation (Ser131Cys) was confirmed by DNA analysis, which identified a ...
TY - JOUR. T1 - Primary amyloidosis as a cause of microvascular angina and intermittent claudication.. AU - Abecasis, Pedro Braga. AU - Soares, Isabel Maria de Seabra Correia. PY - 2005/1/1. Y1 - 2005/1/1. N2 - Primary systemic amyloidosis or AL amyloidosis is a rare condition characterized by extracellular deposits of fibrils composed of fragments of immunoglobulin light chains. Widespread deposition of this amyloid in tissues interferes with their normal function and leads to multiple organ failure. Clinical manifestations are highly variable due to the wide range of organs involved. The heart is affected in 90% of cases; in 30% of these, cardiac dysfunction is the form of presentation and in 50% it is the cause of death. The commonest form of cardiovascular manifestation is congestive heart failure due to restrictive cardiomyopathy caused by extensive interstitial infiltration of amyloid into the myocardium. Occasionally, it can present as angina, due to infiltration of amyloid into the walls ...

Muscle involvement in AL amyloidosis is a rare condition, and the diagnosis of amyloid myopathy is often delayed and underdiagnosed. Amyloid myopathy may be the initial manifestation and may precede the diagnosis of systemic AL amyloidosis. Here, we report the case of a 73-year-old man who was referred to our center for a monoclonal gammopathy of undetermined significance (MGUS) diagnosed since 1999. He reported a progressive weakness of proximal muscles of the legs with onset six months previously. Muscle biopsy showed mild histopathology featuring alterations of nonspecific type with a mixed myopathic and neurogenic involvement, and the diagnostic turning point was the demonstration of characteristic green birefringence under cross-polarized light following Congo red staining of perimysial vessels. Transmission electron microscopy (TEM) confirmed amyloid fibrils around perimysial vessels associated with collagen fibrils. A stepwise approach to diagnosis and staging of this disorder is critical and
Amyloidosis refers to the deposition of the abnormal protein in tissues. In histologic sections, amyloid appears as an amorphous proteinaceous eosinophilic material that demonstrates characteristic apple-green birefringence under polarized light. There are several types of amyloidosis and amyloid proteins, and they can accumulate systemically/diffusely (involving several organs) or in a localized fashion (e.g. nodular). The most common amyloid proteins are AL, AA and transthyretin. AL amyloidosis (formerly primary amyloidosis) derives from immunoglobulin light chains and is the amyloid protein frequently associated with systemic amyloidosis secondary to lymphoproliferative disorders. It is also seen in certain types of localized amyloidosis (e.g. nodular amyloidosis). AA amyloidosis (formerly secondary amyloidosis) is due to the abnormal deposition of the amyloid-associated protein. It is usually seen in chronic inflammatory diseases such as rheumatoid arthritis and inflammatory bowel disease. ...
RATIONALE: Giving melphalan and bortezomib before and after a stem cell transplant stops the growth of abnormal cells by stopping them from dividing or killing them. Giving colony-stimulating factors and certain chemotherapy drugs, helps stem cells move from the bone marrow to the blood so they can be collected and stored. Chemotherapy and monoclonal antibody therapy is then given to prepare the bone marrow for the stem cell transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy.. PURPOSE: This phase II trial is studying how well giving melphalan together with bortezomib followed by stem cell transplant works in treating patients with primary systemic amyloidosis. ...

Renal amyloidosis is a glomerulopathy resulting from glomerular deposition of insoluble fibrillar proteins in the mesangium of the glomerulus. Definition, classification, epidemiology, clinical presentation, diagnosis, and treatment of amyloidosis: see Amyloidosis.. Diagnosis is confirmed by the presence of amyloid protein on immunofluorescence and electron microscopy. Many different types of amyloid protein exist, but the two most common subtypes are AL and AA amyloid:. 1) AL amyloidosis is the most common renal amyloidosis. It results in organized deposits of light chains in the glomerulus. Renal involvement occurs in approximately 50% of patients and manifests as decreased renal function and proteinuria. Nephrotic syndrome can occur. Hypertension is usually absent and the kidneys are often enlarged. Renal treatment response is related to the degree of improvement in light chain production from the underlying condition. Proteinuria and renal function improve with successful therapy.. 2) AA ...

This is the first reported patient with primary amyloidosis to undergo ...
High-dose melphalan with autologous stem cell transplantation (ASCT) can induce durable haematological and organ responses in systemic AL amyloidosis (AL). Stringent selection criteria have improved safety of ASCT in AL but most patients are transplant-ineligible. We report our experience of deferred ASCT in AL patients who were transplant-ineligible at presentation but had improvements in organ function after induction chemotherapy, enabling them to undergo ASCT. Twenty-two AL patients underwent deferred ASCT from 2011 to 2017. All had serial organ function and clonal response assessment. Organ involvement and responses were defined by amyloidosis consensus criteria. All patients were transplant-ineligible at presentation, predominantly due to advanced cardiac involvement. All received bortezomib-based therapy, with 100% haematologic response (86% complete response (CR)/very good partial response (VGPR)), enabling reversal of ASCT exclusion criteria. Patients underwent deferred ASCT for ...

Protein aggregation is the cause of several human diseases such as diabetes mellitus type 2, Parkinson s disease, Alzheimer s disease, Huntington s disease, spongiform encephalopathies, congestive heart failure or dialysis-related amyloidosis. All of these disorders result from protein misfolding which leads to fibrillization and deposition of amyloid plaques in different parts of the body.Due to high molecular weight of the amyloid fibrils and intrinsic heterogeneity of the intermediate states, protein aggregation is a very challenging field of study for the structural biologist. However, nuclear magnetic resonance (NMR) provides a unique possibility to investigate aggregation at all stages, from the monomer to the fibrils.In this work, structural changes involved in prion diseases and dialysis-related amyloidosis are investigated with the help of various NMR techniques.Prion diseases are caused by the aggregation of the natively α-helical prion protein PrPC into its pathological β-sheet-rich ...
Light chain amyloidosis, a deadly protein misfolding disease, is caused by multiple mutations in cells that are intended to protect the body. Instead, the mutations send misfolded bundles of proteins through the bloodstream, potentially destroying the heart, kidneys, liver or other organs. Mayo Clinic researchers have identified one of these mutations and have shown that the molecules shifting position is as important as its unique shape. The findings appear in the current issue of the journal Structure.
Chronic renal disease is a serious complication of long-term intravenous drug use (IVDU). Recent reports have postulated a changing pattern of underlying nephropathy over the last decades. Retrospective investigation including all patients with prior or present IVDU that underwent renal biopsy because of chronic kidney disease between 01.04.2002 and 31.03.2012 in the city of Frankfurt/Main, Germany. Twenty four patients with IVDU underwent renal biopsy because of progressive chronic kidney disease or proteinuria. Renal AA-amyloidosis was the predominant cause of renal failure in 50% of patients. Membranoproliferative glomerulonephritis (GN) was the second most common cause found in 21%. Patients with AA-amyloidosis were more likely to be HIV infected (67 vs.17%; p=0.036) and tended to have a higher rate of repeated systemic infections (92 vs. 50%; p=0.069). Patients with AA-amyloidosis presented with progressive renal disease and nephrotic-range proteinuria but most patients had no peripheral edema or
Amyloid diseases in man are caused by as many as 23 different pre-cursor proteins already described. Cardiologists predominantly encounter three main types of amyloidosis that affect the heart: light chain (AL) amyloidosis, senile systemic amyloidosis (SSA) and hereditary amyloidosis, most commonly caused by a mutant form of transthyretin. In the third world, secondary amyloid (AA) is more prevalent, due to chronic infections and inadequately treated inflammatory conditions. Much less common, are the non-transthyretin variants, including mutations of fibrinogen, the apolipoproteins apoA1 and apoA2 and gelsolin. These rarer types do not usually cause significant cardiac compromise. Occurring worldwide, later in life and of less clinical significance, isolated atrial amyloid (IAA) also involves the heart. Heart involvement by amyloid often has devastating consequences. Clinical outcome depends on amyloid type, the extent of systemic involvement and the treatment options available. An exact ...

The systemic amyloidoses are a number of disorders of varying etiology characterized by extracellular protein deposition. The most common form is an acquired amyloidosis secondary to multiple myeloma or monoclonal gammopathy of unknown significance (MGUS) in which the amyloid is composed of immunoglobulin light chains. In addition to light chain amyloidosis, there are a number of acquired amyloidoses caused by the misfolding and precipitation of a wide variety of proteins. There are also hereditary forms of amyloidosis.. The hereditary amyloidoses comprise a group of autosomal dominant, late-onset diseases that show variable penetrance. A number of genes have been associated with hereditary forms of amyloidosis, including those that encode transthyretin, apolipoprotein AI, apolipoprotein AII, fibrinogen alpha chain, gelsolin, cystatin C and lysozyme. Apolipoprotein AI, apolipoprotein AII, lysozyme, and fibrinogen amyloidosis present as non-neuropathic systemic amyloidosis, with renal dysfunction ...
A 62-year-old male smoker was reviewed for increasing dyspnoea, hoarseness and stridor. The patient underwent a bronchoscopic examination of the airway that revealed two large kissing fleshy tracheal lesions just below the vocal cords (figure 1). A biopsy was taken. The histological image (figure 2) was stained using a Congo Red Staining Kit which selectively demonstrates amyloid in the biopsy sample as bright pink and is marked A in the image. The darker coloured cells represent airway epithelium. Pulmonary amyloidosis is rare and patients may present with tracheobronchial infiltration, parenchymal infiltration (amyloidoma), persistent pleural effusions or pulmonary hypertension. Symptoms of tracheobronchial amyloidosis include hoarseness, stridor, dyspnoea and overt airway obstruction. Invasive bronchoscopic therapies such as argon photocoagulation, bronchoscopic Nd:YAG laser debulking or surgical debulking may be required to relieve the obstruction.1. ...
Familial renal amyloidosis (or familial visceral amyloidosis, or hereditary amyloid nephropathy) is a form of amyloidosis primarily presenting in the kidney. It is associated most commonly with congenital mutations in the fibrinogen alpha chain and classified as a dysfibrinogenemia (see Hereditary Fibrinogen Aα-Chain Amyloidosis). and, less commonly, with congenital mutations in apolipoprotein A1 and lysozyme. It is also known as Ostertag type, after B. Ostertag, who characterized it in 1932 and 1950. Amyloid.

Results were recently published for the first trial of CPHPC as a therapy to clear out age-related deposits of the type of amyloid formed from misfolded transthyretin, normally responsible for transporting the thyroid hormone thyroxine in blood and cerebrospinal fluid. Amyloids are one of the distinguishing features of older tissues, and clearing them will be one of the necessary outcomes produced by any comprehensive suite of rejuvenation therapies developed in the near future.. The accumulation of transthyretin amyloid creates a condition known as senile systemic amyloidosis where it occurs to varying degrees for everyone in later life, and TTR amyloidosis when it arises in young people due to inherited mutations. Senile systemic amyloidosis is known to be responsible for a sizable fraction of deaths in supercentenarians, as the amyloid deposits clog the cardiovascular system to the point of failure. This process is also thought to play an underappreciated role in heart failure in the younger ...
The nonspecific and often vague nature of symptoms that are associated with AL amyloidosis frequently leads to delays in diagnosis such that organ dysfunction is advanced by the time treatment is initiated. The diagnosis of AL amyloidosis should be considered in patients with unexplained proteinuria, cardiomyopathy, neuropathy, or hepatomegaly and in patients with multiple myeloma that has atypical manifestations.. The diagnosis of AL amyloidosis requires (1) demonstration of amyloid in tissue and (2) demonstration of a plasma cell dyscrasia. Tissue amyloid deposits demonstrate apple-green birefringence when stained with Congo red and viewed under polarizing microscopy. Fine-needle aspiration of abdominal fat is a simple procedure that is positive for amyloid deposits in ,70% of patients with AL amyloidosis (15,16). Other tissues that allow for relatively noninvasive biopsy procedures are the minor salivary glands, gingiva, rectum, and skin. However, obtaining tissue from an affected organ may ...

Amyloidosis is the most serious complication of FMF, leading to ESRD. According to older publications amyloidosis occurred in 60% of Turkish patients, in 27% of the non-Ashkenazi Jews, and in only 1-2% of Armenians living in the United States.11 12 The frequent occurrence of amyloidosis and its dramatic variation among different ethnic groups raises a question as to the inherent relation with FMF and whether it is transmitted by the gene for FMF or as a separate genetic trait. The fact that some subjects develop amyloidosis without febrile episodes (phenotype II) may suggest that the predilection for amyloid is a part of the underlying genetic background of FMF. Thus the search for a specific amyloid associated mutation may be a conceivable approach in order to test this hypothesis.. Colchicine has been shown to be effective in controlling attacks of FMF as well as preventing the development of amyloidosis.13Because most of the patients in Israel are treated with colchicine, it is quite ...
Daratumumab, an anti-CD38 antibody, is effective in AL amyloidosis with low tumor burden. Data of daratumumab treatment in patients with AL amyloidosis but high tumor burden (≥ 10% bone marrow plasma cells) is limited. We report retrospective data of ten consecutive patients with high tumor burden treated with daratumumab for relapsed/refractory AL amyloidosis. The median age at diagnosis was 62.3 years, all patients had cardiac involvement, and six (60%) patients had renal involvement. Median bone marrow plasma cell infiltration was 15% (range 10%-40%), and the median difference between involved and non-involved free light-chains (dFLC) was 446 mg/L (range 102-1392 mg/L). Patients had a median of three prior lines of therapy, including bortezomib in all patients, and lenalidomide in seven (70%) patients. The median time to first hematological response was 14 days (range 7-28 days), and the median time to best hematological response was 64 days (range 7-301 days). The hematological overall ...
Purpose: Few scintigraphic tracers are informative on myocardial amyloid infiltration. We aimed to assess: the accuracy of 99mTc-DPD scintigraphy in differential diagnosis between primary (AL) and transthyretin-related (TTR) (both mutant and wild-type) echocardiographically diagnosed amyloidotic cardiomyopathy (AC); the role of 99mTc-DPD in detecting cardiac amyloidosis across a wide spectrum of myocardial involvement in TTR amyloidosis; the prognostic role of 99mTc-DPD in TTR etiology.. Methods: We evaluated: 39 patients with AL-AC; 55 patients with TTR-AC (37 mutant; 19 wild-type); 21 hereditary TTR (ATTR) patients or asymptomatic TTR mutations carriers (6 Val30Met, 15 non-Val30Met) without any echocardiographic abnormalities. Myocardial uptake of 99mTc-DPD (740 MBq iv) was semiquantitatively/visually assessed at 3 h (and 5 min).. Results:.

Systemic AA amyloidosis is a worldwide occurring protein misfolding disease of humans and animals. It arises from the formation of amyloid fibrils from the acute phase protein serum amyloid A. Here, we report the purification and electron cryo-microscopy analysis of amyloid fibrils from a mouse and a human patient with systemic AA amyloidosis. The obtained resolutions are 3.0 Å and 2.7 Å for the murine and human fibril, respectively. The two fibrils differ in fundamental properties, such as presence of right-hand or left-hand twisted cross-β sheets and overall fold of the fibril proteins. Yet, both proteins adopt highly similar β-arch conformations within the N-terminal ~21 residues. Our data demonstrate the importance of the fibril protein N-terminus for the stability of the analyzed amyloid fibril morphologies and suggest strategies of combating this disease by interfering with specific fibril polymorphs ...
The most common cause of death in familial Mediterranean fever is renal failure secondary to amyloidosis (1). Despite the occurrence of extrarenal amyloidosis in patients with this disease, failure of other organs is uncommon (1). At least four patients have been treated with transplantation for renal failure, and no recurrence of amyloidosis has been reported in these allograft kidneys (2-5). (While this paper was in press, a similar report appeared: Benson MD, Skinner M, Cohen AS: Amyloid deposition in renal transplant in familal Mediterranean fever. Ann Intern Med 87:31-34, 1977.). A patient with familial Mediterranean fever who received an allograft ...

Slit-lamp examination showed a milky-white soft mass on her left cornea
Systemic AA amyloid deposition is always accompanied by increased SAA production, whether triggered by tissue damage, infection, or abnormal proinflammatory cytokine activity (26⇓⇓⇓-30). The transgenic mice reported here allowed us to induce expression of the amyloidogenic mouse SAA isoform, SAA2, by oral administration of doxycycline, completely independently of any inflammatory stimulus. Neither doxycycline exposure nor induction of SAA production itself triggered an acute phase response of other proteins. Thus, contrary to claims in the literature, circulating mouse SAA, like authentic human SAA (31), is clearly not intrinsically proinflammatory. Furthermore, although AA amyloidosis has hitherto been inextricably linked to systemic inflammation, the present results demonstrate that isolated overproduction of SAA, without inflammation, is sufficient.. In common with models in which AA amyloidosis is evoked by potently inducing inflammation, transgenic mice induced to express SAA at high ...
Personalized cardiac amyloidosis treatment from experts in AL amyloidosis & TTR amyloidosis. We offer South Carolinas only heart & liver transplant programs.
There are various symptoms of Amyloidosis. The symptoms of Amyloidosis are associated with the organs where the protein deposits are more. If the protein gets deposited in heart, it can cause heart failure and arrhythmia. If the respiratory tract is affected, then there can be blood through sputum and if the protein deposits are around spleen, it can cause ruptured spleen. If the digestive tract is affected, it can lead to diarrhea, vomiting, bleeding through anal canal and so on ...
Amyloidosis is a group of protein misfolding diseases characterized by extracellulardeposition of fibrillar protein aggregates. Today more than 25 different human amyloidogenicproteins have been identified, causing a variety of pathological conditions that includeAlzheimers disease, type 2 diabetes and prion diseases. Amyloid A (AA) amyloidosis is acomplication to long standing inflammatory disorders and amyloid is formed from N-terminalfragments of the acute phase protein serum amyloid A. AA amyloidosis developsspontaneously in many mice strains in response to inflammatory stimulation. Amyloidformation is nucleation dependent and develops after a lag phase of months. If an extract fromamyloid loaded tissue is administered to the animal, the lag phase is shortened to days. Thetissue extract is referred to as amyloid enhancing factor, AEF.. In paper I we demonstrate that the active component of AEF is the amyloid fibril itself. We doalso show that AEF retains its activity over a long period of ...

Systemic amyloidosis (AL) is a plasma cell dyscrasia in which the clone secretes free kappa (κ) or lambda(λ)-immunoglobulin light chains (FLCs).1 These light chains do not fold into the proper tertiary conformation and form protein deposits, causing organ damage.2 The most commonly affected organs are the heart, liver, kidney, gut, and peripheral nerves.3 Standard treatment for patients with good performance status includes high-dose melphalan with autologous stem cell transplantation (ASCT).1,4 Patients with organ dysfunction have increased transplant-related mortality.5,6 Medications that treat AL without increasing the mortality of definitive treatment, currently ASCT, are sought. Bortezomib is a proteasome inhibitor that is effective in the treatment of plasma cell dyscrasias.7 We utilized bortezomib to treat 2 patients with recurrent AL after initial ASCT. Both patients provided written informed consent according to the Helsinki Convention for their initial treatment, for ASCT, for ...
The amyloidoses are a group of rare diseases that are a consequence of abnormal protein (amyloid) deposits in various body tissues and organs. Characterized as systemic or localized, light chain-associated amyloidosis (AL) is the most common form of systemic amyloid disease, with an estimated 4,500 new cases each year in the United States. Systemic amyloid disease can cause serious damage to virtually any organ of the body, including the kidneys, heart, and lungs.. The University of Tennessee Health Science Centers Jonathan Wall, PhD, professor in the Graduate School of Medicine and director of the Amyloidosis and Cancer Theranostics Program in Knoxville, has been studying amyloidosis for over 20 years. He recently received a new three-year grant totaling $1,050,000 from the National Institutes of Health to study Pre-targeting Immunotherapy for Light Chain (AL) Amyloidosis. For this project, Dr. Wall is working to develop a novel, two-stage immunotherapy that will increase the success of ...

Their purpose is to prevent the formation of new deposits of amyloidosis by stabilising Transthyretin and blocking its production. The treatments available so far are only able to slow down the progression and even to stop it but not to get rid of the symptoms already present.. a) Liver transplant The purpose of a liver transplant is to remove the main organ producing abnormal TTR protein even if the liver is functioning perfectly well otherwise. A liver transplant is a complicated operation that needs to be performed in a specialized centre.. This treatment has been offered to over 2000 patients worldwide. It has been effective in stopping the progression of the disease in a large majority of cases (70%) treated in their early stages. It is not advised for patients who developed the disease late in life or for carriers of a certain type of mutation. It cannot be performed on patients over 70 years old.. In spite of the transplant, the disease sometimes continues to develop in the nervous system ...
The amyloid diseases (amyloidoses) are classified according to the type of amyloid protein present as well as the underlying disease. Amyloid diseases have a number of common characteristics including each amyloid consisting of a unique type of amyloid protein. The amyloid diseases include, but are not limited to, the amyloid associated with Alzheimers disease, Downs syndrome, hereditary cerebral hemorrhage with amyloidosis of the Dutch type, dementia pugilistica, inclusion body myositosis (Askanas et al,Ann. Neurol 43:521-560, 1993) and mild cognitive impairment (where the specific amyloid is referred to as beta-amyloid protein or Ap), the amyloid associated with chronic inflammation, various forms of malignancy and Familial Mediterranean Fever (where the specific amyloid is referred to as AA amyloid or inflammation-associated amyloidosis), the amyloid associated with multiple myeloma and other B-cell dyscrasias (where the specific amyloid is referred to as AL amyloid), the amyloid associated ...

The studies by Meyer-Luehman et al. extend insights into the in vivo formation of amyloid deposits by amyloid seeds that may be hetero- and/or homo-amyloidogenic inducers of amyloid fibrillization. This is significant because these types of studies will lead to the clarification of the perplexing conundrum of why there is a frequent co-occurrence of multiple different types of amyloids in neurodegenerative disorders characterized by brain amyloidosis. Indeed, double and triple neurodegenerative brain amyloidoses appear to far exceed in incidence and prevalence any neurodegenerative brain amyloidosis linked to a single amyloidogenic protein or peptide, and this enigma demands clarification if we are to develop more effective therapies for these disorders.. For example, with respect to Aβ deposits, these may occur by themselves as pathological signatures of single brain amyloidoses, such as cerebral amyloid angiopathy (CAA), which most commonly manifests clinically as stroke. This ...
Mid June the Echocardiogram was reviewed and it was clear that the heart had worsened. The question was why. It could be idiopathic, amyloidosis, multiple myeloma or some other rare infiltrative process. It was time to break the silence. Barbie sent out an email to a few friends in California and Connecticut and we told our family. On July 1st, I informed my partners in our monthly meeting that I had restrictive cardiomyopathy and was waiting for a biopsy to determine if it was amyloidosis. I said I would continue to work. The news spread like wildfire. The response was overwhelming and somewhat difficult for me to adjust to. I was not accustom to being the individual in need; my role was always the opposite, to support others in their suffering. I did not want people to worry about me. This would begin a huge personal transformation in how I saw myself and the need to always be in control. This would be a very important life lesson for me.. I was scheduled for a fat biopsy and referred to the ...
Alzheimers disease (AD) is characterized by amyloidosis of brain tissues. This phenomenon is studied with genetically-modified mouse models. We propose a method to quantify amyloidosis in whole 5xFAD mouse brains, a model of AD. We use optical projection tomography (OPT) and a random forest voxel classifier to segment and measure amyloid plaques. We validate our method in a preliminary cross-sectional study, where we measure 6136 +/- 1637, 8477 +/- 3438, and 17267 +/- 4241 plaques (AVG +/- SD) at 11, 17, and 31 weeks. Overall, this method can be used in the evaluation of new treatments against AD.

Alexion Pharmaceuticals, which has a significant research presence in New Haven, is teaming up with a New Jersey-based drugmaker to do clinical testing on a drug designed to treat a rare disorder involving an abnormality of plasma cells in the bone marrow.. The Phase III testing that researchers from Alexion and Caelum Biosciences will be conducting will examine 370 individuals with varying stages of AL amyloidosis to see how they react to the drug candidate CAEL-101. The rare systemic disorder results in a deposit of misfolded amyloid proteins in tissues and organs and typically kills those suffering from it within a year. The testing will focus on how many of the research subjects are able to survive as a result of taking the drug.. Phase III testing is the final step in the drug development process before the federal Food and Drug Administration considers approving a treatment for sale to the public. ...

Monoclonal Gammopathies:. - A characteristic monoclonal band (M-spike) is often found on protein electrophoresis (PEL) in the gamma-globulin region and more rarely in the beta or alpha-2 regions. The finding of a M-spike, restricted migration, or hypogammaglobulinemic PEL pattern is suggestive of a possible monoclonal protein and should be followed by MPSU / Monoclonal Protein Study, 24 Hour, Urine, which includes immunofixation (IF), to identify the immunoglobulin heavy chain and/or light chain.. - A monoclonal IgG or IgA greater than 3 g/dL is consistent with multiple myeloma (MM).. - A monoclonal IgG or IgA less than 3 g/dL may be consistent with monoclonal gammopathy of undetermined significance (MGUS), primary systemic amyloidosis, early or treated myeloma, as well as a number of other monoclonal gammopathies.. - A monoclonal IgM greater than 3 g/dL is consistent with macroglobulinemia.. - The initial identification of a serum M-spike greater than 1.5 g/dL on PEL should be followed by MPSU ...
Missense mutations in APP and PS1 lead to familial forms of AD by different mechanisms. Most PS1 mutations shift γ‐secretase cleavage to increased Aβ42 production, which in turn accelerates cerebral amyloidosis in transgenic mice (Borchelt et al, 1997; Holcomb et al, 1998; Siman et al, 2000). An inverse correlation between the Aβ42 to Aβ40 ratio and the age of onset in familial AD has also been reported (Duering et al, 2005).. Mutations at position Leu 166 in PS1 lead to a severe course of AD pathology, with a very early onset in the third or fourth decade of life. So far, three mutations at position Leu 166 (L166A, L166P and L166H) have been described; the L166P mutation seems to be the most pathogenic (Ezquerra et al, 2000; Moehlmann et al, 2002; Pantieri et al, 2005). Expressing PS1‐L166P in transfected cells resulted in the highest Aβ42 to Aβ40 ratio among several PS1 mutations (Moehlmann et al, 2002). However, in contrast to other PS1 mutations, the L166P mutation has been shown ...

The green tea that you drink to lose those extra pounds has many other powerful effects as a compound found in this super-drink may have a life saving potential for people with bone-marrow disorders, reveals a study.. The research appeared in the Journal of Biological Chemistry.. Researchers from Washington University in St. Louis in the U.S. and their German collaborators found that a compound epigallocatechine-3-gallate (EGCG), a polyphenol found in green tea leaves, may be of particular benefit to patients struggling with multiple myeloma and amyloidosis, often-fatal medical complications associated with bone-marrow disorders.. These patients are susceptible to a frequently fatal condition called light chain amyloidosis, in which parts of the bodys own antibodies become misshapen and can accumulate in various organs, including the heart and kidneys, said study author Jan Bieschke from Washington University in St. Louis in the U.S.. The idea here is twofold: We wanted to understand how ...

The amyloidoses comprise a heterogeneous group of diseases in which 1 out of more than 25 human proteins aggregates into characteristic beta-sheet fibrils with some unique properties. Aggregation is nucleation dependent. Among the known amyloid-forming constituents is the prion protein, well known for its ability to transmit misfolding and disease from one individual to another. There is increasing evidence that other amyloid forms also may be transmissible but only if certain prerequisites are fulfilled. One of these forms is systemic AA-amyloidosis in which an acute-phase reactant, serum AA, is over-expressed and, possibly after cleavage, aggregates into amyloid fibrils, causing disease. In a mouse model, this disorder can easily be transmitted from one animal to another both by intravenous and oral routes. Also, synthetic amyloid-like fibrils made from defined small peptides have this property, indicating a prion-like transmission mechanism. Even some fibrils occurring in the environment can ...
Plasma cell dyscrasias are characterized by uncontrolled proliferation of a single clone of B cells which is responsible for the secretion of a monoclonal immunoglobulin (Ig) or Ig subunit that can become deposited in tissues. They can cause a wide range of renal diseases.Light-chain amyloidosis-renal presentation is usually with proteinuria, often progressing to nephrotic syndrome. Progressive decline in renal function usually occurs, leading finally to endstage renal failure. Diagnosis is made by the detection of monoclonal gammopathy in serum and/or urine (90% of cases) in combination with biopsy evidence of amyloid- forming light chain deposits. Chemotherapy with oral mephalan plus dexamethasone should be considered as first line treatment....
