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.

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.Nephrotic Syndrome: A condition characterized by severe PROTEINURIA, greater than 3.5 g/day in an average adult. The substantial loss of protein in the urine results in complications such as HYPOPROTEINEMIA; generalized EDEMA; HYPERTENSION; and HYPERLIPIDEMIAS. Diseases associated with nephrotic syndrome generally cause chronic kidney dysfunction.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.

It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses. (Cline et al., Dictionary of Visual Science, 4th ed)Extracellular Matrix Proteins: Macromolecular organic compounds that contain carbon, hydrogen, oxygen, nitrogen, and usually, sulfur. These macromolecules (proteins) form an intricate meshwork in which cells are embedded to construct tissues. Variations in the relative types of macromolecules and their organization determine the type of extracellular matrix, each adapted to the functional requirements of the tissue. The two main classes of macromolecules that form the extracellular matrix are: glycosaminoglycans, usually linked to proteins (proteoglycans), and fibrous proteins (e.g., COLLAGEN; ELASTIN; FIBRONECTINS; and LAMININ).Fuchs' Endothelial Dystrophy: Disorder caused by loss of endothelium of the central cornea.

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)

Any of a group of diseases or conditions characterized by the formation and deposition of amyloid in various organs and tissues of the body.
Background. Familial Amyloidosis with Polyneuropathy (FAP) is an autosomal dominantly inherited systemic amyloid disease. The disease is caused by mutations in the transthyretin (TTR) gene, where close to 100 different amyloidogenic mutations have been identified. FAP is found worldwide, but endemic areas with a high frequency of patients are found in Portugal, Japan and northern Sweden. Cases from these endemic areas all share the same TTR c.148G,A, p.V50M ("V30M") mutation, but the phenotype of the disease varies between the areas, and also within the endemic areas. The mean onset of the disease is two decades earlier in Portugal and Japan compared to Sweden, but late as well as early age at onset cases occur within all the populations. Interestingly, the different populations all display a maternal anticipation, where an earlier onset is observed for those individuals who inherit the trait from their mother. Since substantial variation in the phenotype is observed for different populations, ...

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.

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 ...
We identified amyloid derived from a mutant fibrinogen A alpha chain associated with one of the hereditary amyloidoses by kidney biopsy. The recognition of molecular and etiologic diversity among amyloidoses has revolutionized the management of systemic amyloidosis and necessitates precision in amyloid typing. Pitfalls and recommendations for the differential diagnosis of renal amyloid and current standards of amyloid typing are briefly discussed. Diagnosis of the amyloidosis type must be based on identification of the chemical composition of the amyloid protein in deposits and not on clinical suspicion, laboratory tests, or genetic testing. A clinical correlation is required to support but not make a diagnosis of amyloid type. If a hereditary form is detected by amyloid protein typing, then molecular studies are indicated. Conversely, in cases in which DNA sequence indicates a mutant amyloid precursor protein, protein analysis of the deposits must provide the definitive evidence. Negative or ...
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 ...

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 ...
Concepts and semantics are crucial for good communication between clinicians and pathologists. Amyloidosis was described more than 150 years ago. Therefore, the terminology related to it is abundant, varied, and sometimes complex. In this report, we intend to discuss several terms related to the disease, with special emphasis on cutaneous amyloidosis. We present a review, from Virchow to present, of the concepts related to amyloidosis: its nature, the classification of cutaneous forms of the disease, and the techniques used in its diagnosis.
DIAGNOSIS. A thorough physical exam and a detailed and accurate account of your medical history are crucial in helping your doctor diagnose amyloidosis. Sophisticated laboratory techniques called electrophoresis or free light chain assays may reveal early evidence of some amyloid proteins.. A diagnosis of amyloidosis is confirmed through biopsy. Biopsy can also determine the specific type of protein involved in the disease.. Genetic testing will be done if your health care provider suspects you have a type that is passed down through families. Treatment for hereditary amyloidosis is different than for other types of the disease.. Other blood, urine, and imaging tests will be done to check organ function.. RECOMMENDED MEDICATIONS. There is no cure for amyloidosis. Your doctor will prescribe treatments to suppress the development of the amyloid-forming protein, and to manage your symptoms. If amyloidosis is related to another condition, then treatment will include targeting that underlying ...
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 ...
... refers to a group of conditions in which proteins (amyloids) accumulate in the bodys organs and tissues in abnormal amounts, disrupting normal functions. Amyloidosis may be caused by a bone marrow cell disorder or an inherited protein variation. Or it may be associated with other conditions, including chronic infections or chronic inflammatory diseases.. Organs most often affected by amyloidosis include the heart, liver, kidney, skin, and certain nerves. But any organ system may be involved. Symptoms of amyloidosis depend upon the organ system affected and may not help determine what condition is causing the protein accumulation. Amyloidosis can be disabling and even life-threatening.. Treatment of amyloidosis depends upon the condition that is causing the protein accumulation. Treatment options may include medicine or stem cell transplant.. ...
Before taking the steps to participate in any of our research projects, please read the article here.. Amyloidosis. Lead contact: Maria Longeri - University of Milan ([email protected]). Introduction. Amyloidosis is characterized by abnormal deposits of a protein complex (amyloid) in tissues and organs, which affects their functions and eventually can lead to organ failure and death. It occurs in both wild and domestic felids, including random-bred cats. Amyloidosis is well known as a familial trait in the Abyssinian/Somali breeds that mainly affects the kidneys, and in the Siamese/Oriental breeds that mainly affects the liver.. In humans, several types of amyloidosis exist and are associated with myeloma, Alzheimers disease, and chronic inflammatory diseases. Single genes have also been identified as causes for different inherited forms of amyloidosis. Therefore, Feline Amyloidosis is an interesting model for understanding the cause and development of the similar human ...

Drs Acharya, Grogan and Abou-Ezzeddine from Mayo discuss amyloid and TTR cardiac amyloidosis, with particular focus on diagnostic challenges and use of the pyrophosphate (PYP) scan.
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.. We used a T1 assessment sequence similar to that employed by Maceira et al. (5) But, rather than quantitatively calculating T1 offline in an effort to examine gadolinium kinetics, our goal was to prospectively test a practical approach to acquiring and interpreting the images in a "real-life" referral population. Our visual T1 assessment approach was based on the concept that to ...

In the kidneys, as a result of benign arterial hypertension, hyaline (pink, amorphous, homogeneous material) accumulates in the walls of small arteries and arterioles, producing the thickening of their walls and the narrowing of the arterial openings, a process known as arteriolosclerosis. The resulting inadequate blood flow produces tubular atrophy, interstitial fibrosis, and glomerular alterations (smaller glomeruli with different degrees of hyalinization - from mild to sclerosis of glomeruli) and scarring around the glomeruli (periglomerular fibrosis). In advanced stages, kidney failure will occur. Functional nephrons[5] have dilated tubules, often with hyaline casts in the opening of the tubules. Additional complications often associated with hypertensive nephropathy include glomerular damage resulting in protein and blood in the urine. Hypertensive nephropathy refers to kidney failure that can be attributed to a history of hypertension[6] It is a chronic condition and it is a serious risk ...
