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.Amyloidosis, Familial: Diseases in which there is a familial pattern of AMYLOIDOSIS.Amyloid: 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.Serum Amyloid A Protein: 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.Prealbumin: A tetrameric protein, molecular weight between 50,000 and 70,000, consisting of 4 equal chains, and migrating on electrophoresis in 3 fractions more mobile than serum albumin. Its concentration ranges from 7 to 33 per cent in the serum, but levels decrease in liver disease.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.Familial Mediterranean Fever: A group of HEREDITARY AUTOINFLAMMATION DISEASES, characterized by recurrent fever, abdominal pain, headache, rash, PLEURISY; and ARTHRITIS. ORCHITIS; benign MENINGITIS; and AMYLOIDOSIS may also occur. Homozygous or compound heterozygous mutations in marenostrin gene result in autosomal recessive transmission; simple heterozygous, autosomal dominant form of the disease.Amyloid Neuropathies: Disorders of the peripheral nervous system associated with the deposition of AMYLOID in nerve tissue. Familial, primary (nonfamilial), and secondary forms have been described. Some familial subtypes demonstrate an autosomal dominant pattern of inheritance. Clinical manifestations include sensory loss, mild weakness, autonomic dysfunction, and CARPAL TUNNEL SYNDROME. (Adams et al., Principles of Neurology, 6th ed, p1349)Congo Red: An acid dye used in testing for hydrochloric acid in gastric contents. It is also used histologically to test for AMYLOIDOSIS.Amyloid Neuropathies, Familial: Inherited disorders of the peripheral nervous system associated with the deposition of AMYLOID in nerve tissue. The different clinical types based on symptoms correspond to the presence of a variety of mutations in several different proteins including transthyretin (PREALBUMIN); APOLIPOPROTEIN A-I; and GELSOLIN.Cardiomyopathies: A group of diseases in which the dominant feature is the involvement of the CARDIAC MUSCLE itself. Cardiomyopathies are classified according to their predominant pathophysiological features (DILATED CARDIOMYOPATHY; HYPERTROPHIC CARDIOMYOPATHY; RESTRICTIVE CARDIOMYOPATHY) or their etiological/pathological factors (CARDIOMYOPATHY, ALCOHOLIC; ENDOCARDIAL FIBROELASTOSIS).beta 2-Microglobulin: An 11-kDa protein associated with the outer membrane of many cells including lymphocytes. It is the small subunit of the MHC class I molecule. Association with beta 2-microglobulin is generally required for the transport of class I heavy chains from the endoplasmic reticulum to the cell surface. Beta 2-microglobulin is present in small amounts in serum, csf, and urine of normal people, and to a much greater degree in the urine and plasma of patients with tubular proteinemia, renal failure, or kidney transplants.Serum Amyloid P-Component: Amyloid P component is a small, non-fibrillar glycoprotein found in normal serum and in all amyloid deposits. It has a pentagonal (pentaxin) structure. It is an acute phase protein, modulates immunologic responses, inhibits ELASTASE, and has been suggested as an indicator of LIVER DISEASE.Monoamine Oxidase Inhibitors: A chemically heterogeneous group of drugs that have in common the ability to block oxidative deamination of naturally occurring monoamines. (From Gilman, et al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed, p414)Paraproteinemias: A group of related diseases characterized by an unbalanced or disproportionate proliferation of immunoglobulin-producing cells, usually from a single clone. These cells frequently secrete a structurally homogeneous immunoglobulin (M-component) and/or an abnormal immunoglobulin.Tracheal DiseasesKidney Diseases: Pathological processes of the KIDNEY or its component tissues.Macroglossia: The presence of an excessively large tongue, which may be congenital or may develop as a result of a tumor or edema due to obstruction of lymphatic vessels, or it may occur in association with hyperpituitarism or acromegaly. It also may be associated with malocclusion because of pressure of the tongue on the teeth. (From Jablonski, Dictionary of Dentistry, 1992)Amyloidogenic Proteins: Proteins that form the core of amyloid fibrils. For example, the core of amyloid A is formed from amyloid A protein, also known as serum amyloid A protein or SAA protein.Medication Adherence: Voluntary cooperation of the patient in taking drugs or medicine as prescribed. This includes timing, dosage, and frequency.Bence Jones Protein: An abnormal protein with unusual thermosolubility characteristics that is found in the urine of patients with MULTIPLE MYELOMA.Biopsy: Removal and pathologic examination of specimens in the form of small pieces of tissue from the living body.Acinonyx: A genus of long-legged, swift-moving felines (FELIDAE) from Africa (and formerly Asia) about the size of a small leopard.Immunoglobulin lambda-Chains: One of the types of light chain subunits of the immunoglobulins with a molecular weight of approximately 22 kDa.Gelsolin: A 90-kDa protein produced by macrophages that severs ACTIN filaments and forms a cap on the newly exposed filament end. Gelsolin is activated by CALCIUM ions and participates in the assembly and disassembly of actin, thereby increasing the motility of some CELLS.Factor X Deficiency: Blood coagulation disorder usually inherited as an autosomal recessive trait, though it can be acquired. It is characterized by defective activity in both the intrinsic and extrinsic pathways, impaired thromboplastin time, and impaired prothrombin consumption.Skin Diseases, Genetic: Diseases of the skin with a genetic component, usually the result of various inborn errors of metabolism.Fatal Outcome: Death resulting from the presence of a disease in an individual, as shown by a single case report or a limited number of patients. This should be differentiated from DEATH, the physiological cessation of life and from MORTALITY, an epidemiological or statistical concept.Multiple Myeloma: A malignancy of mature PLASMA CELLS engaging in monoclonal immunoglobulin production. It is characterized by hyperglobulinemia, excess Bence-Jones proteins (free monoclonal IMMUNOGLOBULIN LIGHT CHAINS) in the urine, skeletal destruction, bone pain, and fractures. Other features include ANEMIA; HYPERCALCEMIA; and RENAL INSUFFICIENCY.

Furin initiates gelsolin familial amyloidosis in the Golgi through a defect in Ca(2+) stabilization. (1/67)

Hereditary familial amyloidosis of Finnish type (FAF) leading to amyloid in the peripheral and central nervous systems stems from deposition of a 71 residue fragment generated from the D187N/Y variants of plasma gelsolin by two sequential endoproteolytic events. We identify the protease accomplishing the first cleavage as furin, a proprotein convertase. Endoproteolysis of plasma gelsolin occurs in the trans-Golgi network due to the inability of the FAF variants to bind and be stabilized by Ca(2+). Secretion and processing of the FAF variants by furin can be uncoupled by blocking the convergence of the exocytic pathway transporting plasma gelsolin and the endocytic recycling of furin. We propose that coincidence of membrane trafficking pathways contributes to the development of proteolysis-initiated amyloid disease.  (+info)

Misdiagnosis of hereditary amyloidosis as AL (primary) amyloidosis. (2/67)

BACKGROUND: Hereditary, autosomal dominant amyloidosis, caused by mutations in the genes encoding transthyretin, fibrinogen A alpha-chain, lysozyme, or apolipoprotein A-I, is thought to be extremely rare and is not routinely included in the differential diagnosis of systemic amyloidosis unless there is a family history. METHODS: We studied 350 patients with systemic amyloidosis, in whom a diagnosis of the light-chain (AL) type of the disorder had been suggested by clinical and laboratory findings and by the absence of a family history, to assess whether they had amyloidogenic mutations. RESULTS: Amyloidogenic mutations were present in 34 of the 350 patients (9.7 percent), most often in the genes encoding fibrinogen A alpha-chain (18 patients) and transthyretin (13 patients). In all 34 of these patients, the diagnosis of hereditary amyloidosis was confirmed by additional investigations. A low-grade monoclonal gammopathy was detected in 8 of the 34 patients (24 percent). CONCLUSIONS: A genetic cause should be sought in all patients with amyloidosis that is not the reactive systemic amyloid A type and in whom confirmation of the AL type cannot be obtained.  (+info)

Mutational spectrum in the MEFV and TNFRSF1A genes in patients suffering from AA amyloidosis and recurrent inflammatory attacks. (3/67)

BACKGROUND: Among hereditary fevers characterized by recurrent attacks of fever and organ localized inflammation, familial Mediterranean fever (FMF), and tumour necrosis factor receptor superfamily 1A (TNFRSF1A) receptor associated periodic syndrome (TRAPS) are diseases with identified genes that can be associated with renal amyloidosis of the AA type. In this study we have characterized FMF and TRAPS genotypes in 38 unrelated patients suffering from amyloidosis AA and recurrent inflammatory attacks. METHODS: Mutations of the MEFV and TNFRSF1A genes, responsible respectively for FMF and TRAPS, were searched for by amplifying, using polymerase chain reaction (PCR), genomic DNA, and direct sequencing. RESULTS: Twenty-seven patients (71%) carried mutations in MEFV (22 patients with two mutations, two patients with a single mutation) or TNFRSF1A genes (three patients). Patients with MEFV mutations belonged to the classical at-risk ethnic group for FMF: Sephardic Jews, Turks, Armenians, and Arabs from the Maghreb. The main genotype encountered was M694V/M694V (19/22), one Turkish patient was M680I/M680I, and two Arab patients from the Maghreb were M694I/M694I. We found three Caucasian patients with the C55S, C70Y, R92Q mutations in the TNFRSF1A gene. CONCLUSIONS: In this series we observed that FMF is the main cause of AA amyloidosis in Sephardic Jews and Turks. MEFV and TNFRSF1A mutations were found in only 6 of 14 Arab patients from the Maghreb. We found three families (one Caucasian and two from Maghreb) with AA amyloidosis without MEFV or TNFRSF1A mutations, suggesting that other genetic cause(s) exist(s). The characterization of mutations in MEFV and TNFRSF1A is important for the therapeutic behaviour of AA amyloidosis associated with inherited recurrent fever.  (+info)

Immunoglobulin light chain variable (V) region genes influence clinical presentation and outcome in light chain-associated amyloidosis (AL). (4/67)

Light chain-associated amyloidosis (AL) is a plasma cell dyscrasia in which the secreted monoclonal immunoglobulin (Ig) light chains form amyloid fibrils. There is considerable heterogeneity in clinical presentation, and prognosis of the disease relates to the severity of organ dysfunction induced by amyloid deposits. The mechanisms by which the amyloid fibrils are deposited as well as the predilection for specific organ sites have not been clearly elucidated. This study characterizes the repertoire of immunoglobulin light chain variable genes used by the clonal B cell in AL amyloid patients, and the association of light chain variable region (VL) genes with clinical presentation and outcome is assessed in 58 (32 lambda and 26 kappa) patients. A preferential use of VL germ-line genes was noted for both AL kappa and lambda patients. There was a significant correlation between the use of the Vlambda VI germ-line donor, 6a, and renal involvement as well as the Vlambda III gene, 3r, with soft-tissue AL. The use of a biased VL gene repertoire also correlated with clinical outcome, revealing important trends for predicting prognosis. The use of Vlambda II germ-line genes was associated with cardiac amyloidosis and affected survival adversely. The presence of multiple myeloma also correlated with a poor prognosis. The presence of renal disease, on the other hand, was associated with improved survival. Therefore, identification of the clonal VL gene in AL has important implications in determining clinical outcome.  (+info)

Simulations of human lysozyme: probing the conformations triggering amyloidosis. (5/67)

A natural mutant of human lysozyme, D67H, causes hereditary systemic nonneuropathic amyloidosis, which can be fatal. In this disease, insoluble beta-stranded fibrils (amyloids) are found in tissues stemming from the aggregation of partially folded intermediates of the mutant. In this study, we specifically compare the conformation and properties of the structures adopted from the induced unfolding, at elevated temperature, using molecular dynamics. To increase the sampling of the unfolding conformational landscape, three 5 ns trajectories are performed for each of the wild-type and mutant D67H proteins resulting in a total of 30 ns simulation. Our results show that the mutant unfolds slightly faster than the wild-type with both wild-type and mutant proteins losing most of their native secondary structure within the first 2 ns. They both develop random transient beta-strands across the whole polypeptide chain. Clustering analysis of all the conformations shows that a high population of the mutant protein conformations have a distorted beta-domain. This is consistent with experimental results suggesting that this region is pivotal in the formation of conformations prone to act as "seeds" for amyloid fiber formation.  (+info)

Identification of S-sulfonation and S-thiolation of a novel transthyretin Phe33Cys variant from a patient diagnosed with familial transthyretin amyloidosis. (6/67)

Familial transthyretin amyloidosis (ATTR) is an autosomal dominant disorder associated with a variant form of the plasma carrier protein transthyretin (TTR). Amyloid fibrils consisting of variant TTR, wild-type TTR, and TTR fragments deposit in tissues and organs. The diagnosis of ATTR relies on the identification of pathologic TTR variants in plasma of symptomatic individuals who have biopsy proven amyloid disease. Previously, we have developed a mass spectrometry-based approach, in combination with direct DNA sequence analysis, to fully identify TTR variants. Our methodology uses immunoprecipitation to isolate TTR from serum, and electrospray ionization and matrix-assisted laser desorption/ionization mass spectrometry (MS) peptide mapping to identify TTR variants and posttranslational modifications. Unambiguous identification of the amino acid substitution is performed using tandem MS (MS/MS) analysis and confirmed by direct DNA sequence analysis. The MS and MS/MS analyses also yield information about posttranslational modifications. Using this approach, we have recently identified a novel pathologic TTR variant. This variant has an amino acid substitution (Phe --> Cys) at position 33. In addition, like the Cys10 present in the wild type and in this variant, the Cys33 residue was both S-sulfonated and S-thiolated (conjugated to cysteine, cysteinylglycine, and glutathione). These adducts may play a role in the TTR fibrillogenesis.  (+info)

Safety of colchicine therapy during pregnancy. (7/67)

QUESTION: A 27-year-old patient in our clinic with familial Mediterranean fever (FMF) has been treated with colchicine for the last decade. She is planning her first pregnancy. What recommendations should we give her regarding use of colchicine before and during pregnancy, bearing in mind that discontinuation of colchicine could lead to complications from amyloidosis? ANSWER: Colchicine passes through the placenta in humans, is teratogenic in animals, and raises rates of male and female infertility. Based on several patients with chromosomal anomalies, some authorities recommend that patients who require colchicine therapy during pregnancy undergo amniocentesis with karyotyping. In contrast, an increasing body of evidence suggests that colchicine use throughout pregnancy carries no substantial teratogenic or mutagenic risk when used at recommended doses. Its use prevents febrile attacks of FMF and reduces the frequency of renal complications.  (+info)

Cysteine 10 is a key residue in amyloidogenesis of human transthyretin Val30Met. (8/67)

Type I familial amyloidotic polyneuropathy (FAP), a systemic amyloidosis, is characterized by aggregation of variant transthyretin (TTR Val30Met) into stable, insoluble fibrils. This aggregation is caused by genetic and environmental factors. Genetic factors have been studied extensively. However, little is known about environmental or physiological factors involved in the disease process, and their identification may be important for development of effective treatment. X-ray crystallography of normal and amyloidogenic human TTR Val30Met in type I FAP showed that the -SH side chain of cysteine at position 10 (Cys10) forms a hydrogen bond with Gly57 in normal TTR but not in TTR Val30Met. This result suggests a crucial role for the free Cys10 residue and possible involvement of physiological factors affecting Cys residue reactivity in TTR amyloidogenesis. To analyze amyloidogenesis in vivo, our group generated murine FAP models by transgenic technology, with human TTR Val30Met. The three lines of transgenic mice expressed amyloidogenic mutant TTR (Cys10/Met30), wild-type TTR (Cys10/Val30), and artificial Cys-free mutant TTR (Ser10/Met30). Histochemical investigation showed deposition of amyloid derived from human TTR only in amyloidogenic mutant TTR (Cys10/Met30) mice. Thus, the -SH residue in Cys10 plays a crucial role in TTR Val30Met amyloidogenesis in vivo. These data suggest the possibility of innovative treatment via physiological factors modulating Cys10 residue reactivity.  (+info)

Familial transthyretin amyloidosis (ATTR) is a rare, life-threatening, autosomal dominant disease involving mainly the heart and the peripheral nervous system due to a point mutation of the transthyretin (TTR) gene. By removing the main source of the mutated TTR, liver transplantation (LT) has become the standard treatment for ATTR (1). Because the demand for liver grafts exceeds the number of available organs and because new treatments have recently emerged, screening patients at high risk of death after LT is critical (2).. We identified 215 consecutive patients who underwent LT between 1993 and 2011. The diagnosis was made by the observation of both amyloid deposits in biopsy specimens and a TTR mutation. The pre-operative evaluation included physical examination, electrocardiography, echocardiography, autonomic dysfunction score, and polyneuropathy disability score (PND) calculation. The primary study endpoint was all-cause mortality after LT. The prognostic model predicting the individual ...

Gelatinous drop-like corneal dystrophy, also known as amyloid corneal dystrophy, is a rare form of corneal dystrophy. The disease was described by Nakaizumi as early as 1914. The main pathological features in this dystrophy are mulberry-shaped gelatinous masses beneath the corneal epithelium. Patients suffer from photophobia, foreign body sensation in the cornea. The loss of vision is severe. The amyloid nodules have been found to contain lactoferrin, but the gene encoding lactoferrin is unaffected. This form of corneal amyloidosis appears to be more frequent in Japan. A number of mutations causing this disease have been described in the M1S1 (TACSTD2) gene encoding Tumor-associated calcium signal transducer 2, but not all patients have these mutations, suggesting involvement of other genes. Recurrence within a few years occurs in all patients following corneal transplantation. Soft contact lenses are effective in decreasing recurrences. Nakaizumi, K. : A rare case of corneal dystrophy. Acta. ...
In this study, we have identified two novel homozygous mutations from 3 unrelated GDLD patients with a phenotype well co-segregated with the genotype within their respective families. The insertional mutation of TACSTD2 that was found in 2 of the GDLD patients may have resulted from a flame-shift amino acid alteration with premature termination (p.Ile281SerfsX23) within the transmembrane domain. A substitutive mutation found in 1 of the GDLD patients may have resulted from a nonsense mutation (p.Tyr225X) within a region between the thyroglobulin type-1 and transmembrane domains. The transmembrane domain should support the hydrophobic scaffold which may be fundamental to the membrane binding property of this protein. However, and as far as we know, such a domain structure is only a computationally speculated model from the primary amino acid structure of this protein. Therefore, the subcellular localization of both the wild-type and mutated TACSTD2 proteins was experimentally determined in this ...
Definition of hereditary amyloidosis. Provided by Stedmans medical dictionary and Drugs.com. Includes medical terms and definitions.
Localized cutaneous amyloidosis (LCA) refers to a condition characterized by the deposition of amyloid or amyloid-like proteins in the dermis. Localized cutaneous amyloidosis encompasses several conditions characterized by amyloid deposition, including macular amyloidosis and lichen amyloidosis.
We found a fresh C-terminal amyloidogenic variant of apolipoprotein AI (apoAI), Leu178His inside a People from france kindred, associated with cardiac and larynx amyloidosis and skin lesions with onset during the fourth decade. plasma TTR circulates in plasma bound to high-density lipoprotein and that this interaction happens through binding to apoAI. Consequently we hypothesize that nonmutated TTR might influence deposition of apoAI as amyloid. Hereditary amyloidosis is definitely a group of late-onset autosomal dominating diseases with amyloid deposition in various cells. 1 Although a few, such as Alzheimers disease, give rise to localized disorders, most forms of amyloidosis have systemic distribution. The most frequent form of systemic hereditary amyloidosis is definitely associated with variant forms of transthyretin (TTR) 2 and causes both neuropathies and cardiomyopathies. Several other GW-786034 proteins will also be responsible for varied clinical forms of hereditary amyloidosis: ...
Introduction. Gelatinous drop-like corneal dystrophy (GDLD, OMIM 204870) is an abnormality, characterized by subepithelial deposits of amyloid and severe impairment of visual acuity leading to blindness. GDLD is an autosomal recessive disorder, described primarily in Japanese patients with an estimated prevalence of 1 in 30,000 [1-5]. It occurs also in Vietnamese [6], Indian [7,8], and Tunisian [8-10] families. A few cases have been reported in European and North American patients [8,11-13]. Early clinical symptoms of GDLD include blurred vision, severe photophobia, and ocular foreign body sensation. As the disease progresses, raised gelatinous masses accumulate on the cornea, which impair severely the visual acuity. Repeated lamellar or perforating keratoplasties is presently the only treatment option, but they do not prevent recurrence [14]. Homozygous or compound heterozygous mutations in the M1S1 (alias TROP-2) gene seem to be causative for GDLD in Japanese families [15]. The gene location ...

Cardiac amyloidosis. Section through a heart from a person affected by primary systemic amyloidosis. Amyloidosis is characterised by a build-up of the protein amyloid. Primary systemic amyloidosis, or amyloid light-chain (AL) amyloidosis, is caused by malfunctioning antibody-producing cells that produce abnormal protein fibres (light chains), which clump together to form amyloid deposits in the bodys organs. There is no cure for amyloidosis, but the production of amyloid in the body can be slowed down by certain medications. - Stock Image C023/5511
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 ...
Q: How does cardiac involvement affect the prognosis of patients with AL amyloidosis?. A: Clinical cardiac involvement occurs in up to 50% of cases and is a poor prognostic sign, conferring a life expectancy of less than 6 months if left untreated. In contrast to the indolent nature of cardiovascular involvement in transthyretin-associated amyloidoses, cardiac disease in AL amyloidosis can be rapidly progressive; light chains may contribute to the damage through direct toxic effects on the myocardium.. Q: How is AL amyloidosis treated?. A: Chemotherapy may result in a cure or prolong life in patients with AL amyloidosis. In a case series of patients treated with high-dose chemotherapy and autologous stem-cell transplantation, treatment-related mortality was high but approximately 75% of the patients were alive at 1 year, and 40% of these patients had a complete hematologic response. When patients are ineligible this type of treatment, high-dose dexamethasone and melphalan has been reported to ...

In this study, we tested the utility of a modified DE-CMR protocol to provide diagnostic and prognostic information in patients referred for suspected cardiac amyloidosis. Although several investigations have described a characteristic pattern on conventional DE-CMR-diffuse global subendocardial HE with variable epicardial extension (4-9)-it is commonly reported that imaging is difficult and that quality is often suboptimal (5-7,9,24). This is because conventional DE-CMR relies on correctly setting an imaging parameter (inversion time) to null signal from "normal" myocardium, yet normal myocardium may be absent in CA..

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 ...
... 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 ...
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). ...
This case report concerns a patient who presented a diagnostic problem of cardiomegaly and myocardial failure of unknown etiology and in whom the outstanding pathologic finding at autopsy was primary systemic amyloidosis with marked cardiac involvement. An additional finding of great interest was the presence of numerous Russell bodies in the bone marrow. For previously reported cases (approximately 100) and reviews of the literature of primary systemic amyloidosis,1-14 we found no report of similar bone marrow findings though Snapper, Turner and Moscovitz15 have reported Russell bodies in the bone marrow in atypical amyloidosis accompanying multiple myeloma. Morphologically, amyloidosis associated with ...
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 ...
TY - JOUR. T1 - Pathology and diagnosis of renal non-AL amyloidosis. AU - Sethi, Sanjeev M. AU - Theis, Jason D.. PY - 2017/8/21. Y1 - 2017/8/21. N2 - Renal amyloidosis is characterized by acellular Congo red positive deposits in the glomeruli, interstitium and/or arteries. Light chain restriction on immunofluorescence studies is present in AL-amyloidosis, the most common type of amyloidosis involving the kidney. The detection of Congo red positive deposits coupled with negative immunofluorescence studies is highly suggestive of non-AL amyloidosis. Some of the non-AL amyloidosis are common while others are relatively rare. The clinical features, laboratory and renal pathology findings are helpful in the diagnosis and typing of non-AL amyloidosis. Thus, ALECT2 amyloidosis is characterized by diffuse cortical interstitial amyloid deposits, AA amyloidosis shows vascular deposits in addition to the glomerular deposits, AFib amyloidosis is characterized by massive amyloid accumulation limited to the ...
Background. Renal amyloidosis results from protein misfolding and leads to progressive renal insufficiency. Few data are available concerning the relevance of the histomorphological patterns and the dynamics of the disease process.. Methods. Cases of renal amyloidosis in native kidney biopsies (n = 203) were retrospectively evaluated for the pattern of amyloid distribution, the extent of glomerular amyloid deposition and the amount of interstitial fibrosis and tubular atrophy. One hundred and fifty-eight cases were characterized by immunohistochemistry to determine the biochemical amyloid type. Morphological findings were correlated with available clinical data.. Results. According to the predominant site of amyloid deposition, 84.6% showed a glomerular, 9.4% a vascular and 6% a tubulointerstitial distribution pattern. Within the glomeruli, amyloid was initially deposited in a focal segmental fashion that became diffuse and global in later stages. Most cases were identified as AL lambda (84/158) ...
Transthyretin (TTR) amyloidoses are familial or sporadic degenerative conditions that often feature heavy cardiac involvement. Presently, no effective pharmacological therapy for TTR amyloidoses is available, mostly due to a substantial lack of knowledge about both the molecular mechanisms of TTR aggregation in tissue and the ensuing functional and viability modifications that occur in aggregate-exposed cells. TTR amyloidoses are of particular interest regarding the relation between functional and viability impairment in aggregate-exposed excitable cells such as peripheral neurons and cardiomyocytes. In particular, the latter cells provide an opportunity to investigate in parallel the electrophysiological and biochemical modifications that take place when the cells are exposed for various lengths of time to variously aggregated wild-type TTR, a condition that characterizes senile systemic amyloidosis. In this study, we investigated biochemical and electrophysiological modifications in ...
Although the gold standard diagnostic tool for cardiac amyloidosis is endomyocardial biopsy (5), investigators have tried to assess this disease noninvasively with various imaging techniques. Although some molecular imaging-based methods have been successful (8,12), most of them have been unsuccessful for demonstrating amyloid deposits in the myocardium (13). The CMR has also been successful in the diagnosis of cardiac amyloidosis (14), but it may not be specific for amyloid deposits (15). Therefore, there is a clinical need to foster imaging-based diagnosis into clinical utility.. 11C-PiB has been used recently for early detection and for follow-up of Alzheimers dementia (16), a disease characterized by accumulation of β-amyloid plaque in the brain parenchyme. It is a radioactive derivative of benzothiazole that binds with conformational dependence to any type of β-amyloid sheet structure (7). Indeed, this has been demonstrated in various mouse models (17) and in human autopsy studies of the ...

Treatment options are limited for systemic amyloidosis. CPHPC efficiently depletes SAP from the plasma, but not SAP in amyloid tissue deposits. Anti-SAP antibodies have previously been shown to initiate clearance of visceral amyloid deposits, presumably by binding to amyloid, activating complement, and recruiting macrophages that engulf the deposits. In this study, which included subjects with different types of systemic amyloidosis, antibody treatment appeared to be safe and effective. Effectiveness of this promising therapy in patients with extensive cardiac amyloidosis will be tested in future trials. ...

Considerable progress is being made towards the development of novel and more effective therapeutic approaches for the treatment of Alzheimers disease (AD) based on a design strategy to prevent or eliminate Aβ- deposits in fibrillar and non-fibrillar lesions in the brains of AD patients, and similar advances are rapidly evolving from efforts to reverse amyloid deposits in organs and tissues other than the brain in many of the systemic amyloidoses (1-3). The increasing realization that insights derived from therapeutic advances in one form of systemic or brain amyloidosis can be exploited to the benefit of treating other amyloidoses due the misfolding of many unrelated mutant and wild type proteins or peptides presents a powerful opportunity for ramping up the pace of progress in treating these disorders (3,4), many of which affect the elderly, the most rapidly increasing segment of the population in developed countries.. While fibrillar Aβ deposits in the extracellular space known as senile ...

Amyloidosis is a rare condition where insoluble proteins produced in the bone marrow called "amyloids" collect in various organs. However, several diseases feature amyloid depositions (e.g. Alzheimer's, rheumatoid arthritis and dozens more). Therefore, the testing process begins with a blood and urine test to screen for amyloids associated with specific diseases. If these markers aren't found, your doctor will order a biopsy--the only way to officially diagnose amyloidosis.Blood and Urine TestsBefore prescribing a tissue biopsy, your doctor may first order a blood or urine test in order to rule out certain conditions. Commonly screened for...

Aim: Cardiac troponins and natriuretic peptides are established for risk stratification in light-chain amyloidosis. Data on cardiac biomarkers in transthyretin amyloidosis (ATTR) are lacking.. Methods and results: Patients (n = 1617) with any of the following cardiac biomarkers, BNP (n = 1079), NT-proBNP (n = 550), troponin T (n = 274), and troponin I (n = 108), available at baseline in the Transthyretin Amyloidosis Outcomes Survey (THAOS) were analyzed for differences between genotypes and phenotypes and their association with survival. Median level of BNP was 68.0 pg/mL (IQR 30.5-194.9), NT-proBNP 337.9 pg/mL (IQR 73.0-2584.0), troponin T 0.03 μg/L (IQR 0.01-0.05), and troponin I 0.08 μg/L (IQR 0.04-0.13). NT-proBNP and BNP were higher in wild-type than mutant-type ATTR, troponin T and I did not differ, respectively. Non-Val30Met patients had higher BNP, NT-proBNP and troponin T levels than Val30Met patients, but not troponin I. Late-onset Val30Met was associated with higher levels of ...
Transthyretin amyloidosis is caused by deposition of hepatocyte-derived transthyretin amyloid in peripheral nerves and heart.

The RNAi resulted in sustained reduction of transthyretin levels. This study establishes a proof of concept for RNAi therapy targeting messenger RNA transcribed from a disease-causing gene.. ...
Macular and lichen amyloidosis are common variants of primary localized cutaneous amyloidosis (PLCA) in which clinical features of pruritus and skin scratching are associated with histological findings of deposits of amyloid staining on keratinous debris in the papillary dermis. Most cases are sporadic, but an autosomal dominant family history may be present in up to 10% of cases, consistent with a genetic predisposition in some individuals. Familial PLCA has been mapped to a locus on 5p13.1-q11.2 and in 2008 pathogenic heterozygous missense mutations were identified in the OSMR gene, which encodes oncostatin M receptor β (OSMRβ), an interleukin (IL)-6 family cytokine receptor. OSMRβ is expressed in various cell types, including keratinocytes, cutaneous nerves and nociceptive neurones in dorsal root ganglia; its ligands are oncostatin M and IL-31. All pathogenic mutations are clustered in the fibronectin-III repeat domains of the extracellular part of OSMRβ, sites that are critical for ...
TY - JOUR. T1 - Pathogenesis of transthyretin amyloidosis. AU - Benson, Merrill. PY - 2012/6. Y1 - 2012/6. N2 - Current dogma for transthyretin (TTR) pathogenesis is that mutations in TTR alter its structure such that the tetramer becomes unstable and prone to release of monomer which then becomes the putative building block of the fibril. This hypothesis is supported by thermodynamic data showing decreased stability of mutant TTR tetrameric proteins and accelerated fibril formation under acidic conditions in vitro. There are, however, a number of questions that are not readily answered by this simplistic model of a very complex disease. Worrisome questions still to be answered include: 1. If the monomer is the precursor of the fibril, why do fibril deposits contain large amounts of wild-type TTR and not just variant 2. If destabilized tetramers can form fibrils in vitro, why do we consistently find partial proteolysis of fibril subunit proteins If enzymatic proteolysis is a required step in ...
Cysteineglutathione disulfide is a molecule that is formed upon oxidative stress of glutathione, that will form mixed disulfides with protein thiol groups, causing reversible S-glutathionylation. S-glutathionylation is an important post-translational modification responsible for transducing oxidant signals. S-glutathionylation of thiols confers protection against their irreversible oxidation, like for instance the formation of sulphonic acid moieties. If the targeted cysteine is a functionally critical amino acid, S-glutathionylation will however also modify protein function. (PMID 16515838 ). S-sulfonation and S-thiolation of transthyretin Phe33Cys has been detected in a patient with familial transthyretin amyloidosis. (PMID 12876326 ). In Cystinotic human skin fibroblasts in tissue culture there is an accumulation of cystine.

In this, the largest ever CMR study in patients with amyloidosis, we found that native myocardial T1 mapping has a high diagnostic accuracy for cardiac amyloid for both AL and ATTR when compared against HCM, a relevant clinical differential diagnosis. Furthermore, T1 tracks cardiac amyloid burden in both diseases, and is more sensitive for detecting early disease in gene mutation carriers than LGE imaging. In both amyloid types, T1 tracks markers of systolic and diastolic function, mass, and prognostic markers. In ATTR amyloid, T1 additionally correlates with ECG PR and QRS duration and indexed left atrial area, whereas in AL type, it correlates with reductions in limb lead voltages. T1 also has functional associations with a reduction in 6-min walk test in ATTR amyloidosis. Interestingly and perhaps unexpectedly (16), T1 elevation was lower in ATTR compared with AL type.. Amyloidosis is considered the exemplar of an interstitial disease, as the quantity of amyloid in the extracellular space ...
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 ...

Background: Cardiac involvement in primary amyloidosis (AL) is associated with poor prognosis. We studied the prognostic significance of clinical, ECG and echocardiographic parameters of patients with primary cardiac amyloidosis.. Methods: 60 patients with primary amyloidosis and cardiac involvement documented by endomyocardial tissue biopsy were studied.. Results: 60 patients (mean age 57.94±10.22 years; 71.67% male and 86.67% Caucasian) were studied. The median survival was 12.23 (median) ±4.43 months, 50% of patients survived for more than 1 year. Congestive heart failure (NYHA II-IV) was present in 60% of patients. Low voltage, Q wave, conduction abnormalities, first degree AV block and abnormal QRS axis were present in 54.24%, 51.72%, 71.67%, 21.67% and 57.72% respectively. Echocardiogram revealed LVH, mitral regurgitation, left atrial enlargement, speckled appearance and pericardial effusion in 82.76%, 62%, 63.16%, 8.77% and 42.11% respectively. LVEF, RVSP, IVS and LVPW were 0.479±.129, ...
Amyloidosis is varieties of conditions that creates normally soluble proteins to become insoluble and are deposited in various spaces in organs or tissues. Due to the improper deposition of these proteins, it disrupts normal body functions. The clumping together of this abnormal proteins are called amyloid deposits. Primary diagnosis of amyloidosis can lead to conditions such as carpal tunnel syndrome, heart muscle damage, intestinal malabsorption, liver swelling, kidney failure, nephrotic syndrome and nerve problems. In other cases, it may lead to orthostatic hypotension, which causes a drop in blood pressure when an invidual stands up. Please note that primary amyloidosis is extremely rare of a condition.
Light-chain (AL) amyloidosis is the most common type of amyloidosis; cardiac involvement is rare but has a poor prognosis. Biventricular hypertrophic cardiomyopathy is an exceptional finding in amyloidosis and its association with obstructive right ventricular gradient is even rarer. We report the case of a male patient with biventricular hypertrophy suggesting amyloidosis, with an obstructive gradient in the right ventricle.. ...
Results The time from the diagnosis of RA to the development of amyloidosis was 4 to 16 years, mean 8,7 years. In all patients advanced radiological changes were observed (radiological Steinbrocker stage III or IV).. The most common symptoms of amyloidosis were: proteinuria-27(62,8%), nephrotic syndrom -12(27,9%), diarrhoea-4(9,3%). In most of the patients the course of RA was very severe since the onset and high activity parameters were observed despite treatment.. Amyloidosis was histologically confirmed by subcutaneous fat tissue biopsy in 38(88,4%) cases. In 8 patients amyloid deposits were found in other organs (kidney, stomach, salivary gland).. After the treatment with cyclophosphamide or methotrexate we observed decrease of some activity parameters (ESR, CRP) and decrease of proteinuria level. The treatment was well tolerated and we didn?t observe serious side effects. In the observed group 7(16,3%) patients died after 3 to 6 years of the diagnosis of amyloidosis. The most common cause ...
The larynx is a rare site of involvement of amyloidosis. We report two cases of laryngeal amyloidosis. Both patients were middle aged females with history of persistent hoarseness. Fibreoptic laryngoscopy used for diagnosis in both and debulking of the tumour was performed. Histopathological examination confirmed the diagnosis of amyloidosis. Appropriate follow up is an important part of the long-term management of the disease.
Background: Upto 30% of patients with multiple myeloma have AL amyloidosis and cardiac involvement is associated with worse outcomes in these patients. Traditional screening modalities including EKG, echocardiography and biomarkers have limited value. The aim of this study was to evaluate the role of "screening" cardiac MRI in a large multiple myeloma population at a large specialized referral center.. Methods & Results: 164 consecutive patients with multiple myeloma who underwent cardiac MRI between 6/2005 and 10/2011 were enrolled in this study. Primary endpoint was all cause death. Clinical, EKG, echocardiographic, biomarker and MRI predictors for death were analyzed. Mean age of population was 63+10 years, 40% females and 16% African Americans. 30% of the population had MRI evidence of cardiac involvement. There were 26 patients who had biopsy proven systemic amyloidosis, of whom 62% showed cardiac involvement on MRI. 81% patients with confirmed cardiac amyloidosis on endomyocardial biopsy ...
On the heels of a report that tauopathy can be spread throughout the brain by the injection of a small amount of toxic tau (see ARF related news story) comes a similar paper on the propagation of amyloid-β (Aβ). In this weeks PNAS online, researchers led by Mathias Jucker, University of Tubingen, Germany, demonstrate that injecting a tiny amount of brain extract containing Aβ aggregates is sufficient to induce and spread amyloidosis through many different areas of the mouse brain. The work supports the idea that toxic protein conformations, such as those adopted by tau, Aβ, α-synuclein, huntingtin, and other proteins that cause a variety of neurodegenerative diseases, can be propagated from protein to protein much like the transmission of prions. "We showed that in every single brain area we can induce amyloid formation by the extract," said Jucker. Thats not to say that Aβ is infectious. Unlike prions, the researchers found no evidence that amyloidosis could be induced by introducing ...
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 ...

Another recent paper from Japan describes the vascular distribution of amyloid and how that changes when it affects the kidney. This paper looked at patient biopsy samples with AL amyloidosis and divided them into a group with capillary form and a group with small vessel form. The small vessel form was associated with more cardiac involvement, and left ventricular thickening compared to the capillary form. There was no significant differences in rates of survival and renal survival. ...

The cause of the electrocardiographic abnormalities in amyloidosis is a matter of controversy despite attempts of clinicopathological correlation. Detailed correlative studies of the involvement of cardiac conduction system in amyloidosis are few and have produced conflicting results. Some authors favour the hypothesis that infiltration of the conducting system by amyloid deposits is the main reason for the disturbances of conduction [19]. In familial amyloidosis with polyneuropathy, amyloid infiltration of the sinus node and atrioventricular conduction system is now well documented, and this seems to account for the majority of the electrophysiological disturbances of these regions [20, 21, 22].The distribution and extent of heart infiltration by amyloid are not, however, uniform. On the other hand, other authors have concluded that direct infiltration by amyloid is of lesser importance [14]. Autonomous neuropathy due to amyloid may also contribute to the electrophysiological disturbances. In ...
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.[
Background: Familial amyloid polyneuropathy related to transthyretin gene (TTR-FAP) is a life-threatening disease transmitted as an autosomal dominant trait. Val30Met mutation accounts for the majority of the patients with large endemic foci especia
BACKGROUND: This study investigated whether a relationship exists between the presence of de novo antibodies and the clinical manifestations of familial amyloidotic polyneuropathy (FAP). METHODS: Serum samples were collected from 25 Japanese and 6 Swedish FAP amyloidogenic transthyretin (ATTR) Valine30Methionine (V30M) patients, 4 asymptomatic Japanese ATTR V30M gene carriers, and 24 Japanese healthy volunteers. Study methods included enzyme-linked immunosorbent assay (ELISA) and mass spectrometry. RESULTS: Three Japanese and 5 Swedish patients had significantly higher levels of antibodies against ATTR than did healthy volunteers and asymptomatic gene carriers (P,0.05). All 8 patients with higher antibody levels were late-onset cases. The ratio of wild-type TTR to ATTR V30M in serum from the high-antibody group was higher than that of the low-antibody group. ELISA results revealed two epitopes at positions 24-35 and 105-115 of ATTR V30M. We found a significant positive correlation between levels ...
PURPOSE: To report the genetic findings in a Chinese patient diagnosed with gelatinous droplike corneal dystrophy (GDLD).. DESIGN: Case report and experimental study.. METHODS: Molecular genetic analysis was performed on the DNA extracted from peripheral leukocytes from a Chinese patient with GDLD and his unaffected parents. Fifty healthy, unrelated, Chinese participants were used as control subjects. The M1S1 gene was amplified by polymerase chain reaction and directly sequenced.. RESULTS: The patient was clinically diagnosed with GDLD. Direct sequencing of the M1S1 gene revealed heterozygous changes in both alleles, a novel Y184C mutation on one allele and a Q118X mutation on the other that was reported as a founder mutation in the Japanese population. The patient′s unaffected parents showed only the heterozygous Q118X or Y184C mutation. The mutation was not detected in the 50 unaffected subjects.. CONCLUSIONS: This is the first genetic analysis of a Chinese patient with GDLD. Because the ...
