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.
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.
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.
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.
Peripheral, autonomic, and cranial nerve disorders that are associated with DIABETES MELLITUS. These conditions usually result from diabetic microvascular injury involving small blood vessels that supply nerves (VASA NERVORUM).

A heterogeneous group of sporadic or familial disorders characterized by AMYLOID deposits in the walls of small and medium sized blood vessels of CEREBRAL CORTEX and MENINGES. Clinical features include multiple, small lobar CEREBRAL HEMORRHAGE; cerebral ischemia (BRAIN ISCHEMIA); and CEREBRAL INFARCTION. Cerebral amyloid angiopathy is unrelated to generalized AMYLOIDOSIS. Amyloidogenic peptides in this condition are nearly always the same ones found in ALZHEIMER DISEASE. (from Kumar: Robbins and Cotran: Pathologic Basis of Disease, 7th ed., 2005)
A group of inherited disorders characterized by degeneration of dorsal root and autonomic ganglion cells, and clinically by loss of sensation and autonomic dysfunction. There are five subtypes. Type I features autosomal dominant inheritance and distal sensory involvement. Type II is characterized by autosomal inheritance and distal and proximal sensory loss. Type III is DYSAUTONOMIA, FAMILIAL. Type IV features insensitivity to pain, heat intolerance, and mental deficiency. Type V is characterized by a selective loss of pain with intact light touch and vibratory sensation. (From Joynt, Clinical Neurology, 1995, Ch51, pp142-4)
Ischemic injury to the OPTIC NERVE which usually affects the OPTIC DISK (optic neuropathy, anterior ischemic) and less frequently the retrobulbar portion of the nerve (optic neuropathy, posterior ischemic). The injury results from occlusion of arterial blood supply which may result from TEMPORAL ARTERITIS; ATHEROSCLEROSIS; COLLAGEN DISEASES; EMBOLISM; DIABETES MELLITUS; and other conditions. The disease primarily occurs in the sixth decade or later and presents with the sudden onset of painless and usually severe monocular visual loss. Anterior ischemic optic neuropathy also features optic disk edema with microhemorrhages. The optic disk appears normal in posterior ischemic optic neuropathy.

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.
Diseases of multiple peripheral nerves simultaneously. Polyneuropathies usually are characterized by symmetrical, bilateral distal motor and sensory impairment with a graded increase in severity distally. The pathological processes affecting peripheral nerves include degeneration of the axon, myelin or both. The various forms of polyneuropathy are categorized by the type of nerve affected (e.g., sensory, motor, or autonomic), by the distribution of nerve injury (e.g., distal vs. proximal), by nerve component primarily affected (e.g., demyelinating vs. axonal), by etiology, or by pattern of inheritance.

Capture of a dimeric intermediate during transthyretin amyloid formation. (1/93)

Point mutations in the human plasma protein transthyretin are associated with the neurological disorder familial amyloidosis with polyneuropathy type 1. The disease is characterized by amyloid fibril deposits causing damage at the site of deposition. Substitution of two amino acids in the hydrophobic core of transthyretin lead to a mutant that was very prone to form amyloid. In addition, this mutant has also been shown to induce a toxic response on a neuroblastoma cell line. Renaturation of the transthyretin mutant at low temperature facilitated the isolation of an amyloid-forming intermediate state having the apparent size of a dimer. Increasing the temperature effectively enhanced the rate of interconversion from a partly denatured protein to mature amyloid. Using circular dichroism the beta-sheet content of the formed mature fibrils was significantly lower than that of the native fold of transthyretin. Morphology studies using electron microscopy also indicated a temperature-dependent transformation from amorphous aggregates toward mature amyloid fibrils. In addition, 1-anilino-8-naphtalenesulfonate fluorescence studies suggested the loss of the thyroxin-binding channel within both the isolated intermediate and the mature fibrils.  (+info)

Deposition of transthyretin in early stages of familial amyloidotic polyneuropathy: evidence for toxicity of nonfibrillar aggregates. (2/93)

Familial amyloidotic polyneuropathy (FAP) is a neurodegenerative disorder characterized by extracellular deposition of transthyretin (TTR) amyloid fibrils, particularly in the peripheral nervous system. No systematic immunohistochemical data exists relating TTR deposition with FAP progression. We assessed nerves from FAP patients in different stages of disease progression (FAP 0 to FAP 3) for TTR deposition by immunohistochemistry, and for the presence of amyloid fibrils by Congo Red staining. The nature of the deposited material was further studied by electron microscopy. We observed that early in FAP (FAP 0), TTR is already deposited in an aggregated nonfibrillar form, negative by Congo Red staining. This suggested that in vivo, preamyloidogenic forms of TTR exist in the nerve, in a stage before fibril formation. Cytotoxicity of nonfibrillar TTR was assessed in nerves of different FAP stages by immunohistochemistry for macrophage colony-stimulating factor. FAP 0 patients already presented increased axonal expression of macrophage colony-stimulating factor that was maintained in all other stages, in sites related to TTR deposition. Toxicity of synthetic TTR fibrils formed in vitro at physiological pH was studied on a Schwannoma cell line by caspase-3 activation assays and showed that early aggregates but not mature fibrils are toxic to cells. Taken together, these results show that nonfibrillar cytotoxic deposits occur in early stages of FAP.  (+info)

Myocardial muscarinic receptor upregulation and normal response to isoproterenol in denervated hearts by familial amyloid polyneuropathy. (3/93)

BACKGROUND: Patients with familial amyloid polyneuropathy, a rare hereditary form of amyloidosis, have progressive autonomic neuropathy. The disease usually does not induce heart failure but is associated with sudden death, conduction disturbances, and an increased risk of complications during anesthesia. Although cardiac sympathetic denervation has been clearly demonstrated, the postsynaptic status of the cardiac autonomic nervous system remains unelucidated. METHODS AND RESULTS: Twenty-one patients were studied (age, 39+/-11 years; normal coronary arteries; left ventricular ejection fraction 68+/-9%). To evaluate the density and affinity constants of myocardial muscarinic receptors, PET with (11)C-MQNB (methylquinuclidinyl benzilate), a specific hydrophilic antagonist, was used. Cardiac beta-receptor functional efficiency was studied by the heart rate (HR) response to intravenous infusion of isoproterenol (5 minutes after 2 mg of atropine, 5, 10, and 15 ng/kg per minute during 5 minutes per step). The mean muscarinic receptor density was higher in patients than in control subjects (B'(max), 35.5+/-8.9 versus 26.1+/-6.7 pmol/mL, P=0.003), without change in receptor affinity. The increase in HR after injection of atropine as well as of MQNB was lower in patients compared with control subjects despite a similar basal HR (DeltaHR after atropine, 11+/-21% versus 62+/-17%; P<0.001), consistent with parasympathetic denervation. Incremental infusion of isoproterenol induced a similar increase in HR in patients and control subjects. CONCLUSIONS: Cardiac autonomic denervation in familial amyloid polyneuropathy results in an upregulation of myocardial muscarinic receptors but without change in cardiac beta-receptor responsiveness to catecholamines.  (+info)

Results of liver transplantation for familial amyloid polyneuropathy type I in Brazil. (4/93)

Familial amyloid polyneuropathy type I (FAP-I) is an inherited amyloidosis secondary to systemic deposition of amyloid fibrils containing mutant transthyretin (TTR) variants. The disease has a progressive clinical course and is usually fatal 10 years after its onset. TTR is mainly produced in hepatocytes, and liver transplantation (LT) has been proposed as an effective treatment for FAP-I. The aim of this study is to evaluate the results of LT for FAP-I in Brazil and analyze prognostic factors associated with survival after surgery. Twenty-four patients (median age, 36 years; range, 25 to 52 years) who underwent LT with the diagnosis of FAP-I were evaluated. Surgery was uneventful in all but six patients who died of complications of primary liver nonfunction (n = 1), cardiogenic shock (n = 1), sepsis (n = 3), and hepatic artery thrombosis (n = 3). Overall 1- and 5-year survival rates were 70% and 58%, respectively. Most patients had stabilization or improvement of symptoms after a median follow-up of 36 months (range, 14 to 82 months). Survivors had a shorter disease duration before LT (median, 6 years; range, 2 to 17 years v 9 years; range, 7 to 12 years; P =.02), greater albumin levels (median, 4 g/dL; range, 3 to 4.7 g/dL v 3.6 g/dL; range, 2.6 to 4.1 g/dL; P =.03), and greater modified body mass index scores (median, 735; range, 502 to 1,432 v 659; range, 411 to 803; P =.04) compared with nonsurvivors. However, only disease duration and albumin levels were independently associated with survival in multivariate analysis. In conclusion, LT is an effective therapy for FAP-I. Mortality after surgery is associated with poor nutritional status and long-standing disease before LT. Thus, LT should be performed as early as possible after the onset of FAP-I symptoms to avoid major disability and improve survival.  (+info)

Long-term follow-up of survival of liver transplant recipients with familial amyloid polyneuropathy (Portuguese type). (5/93)

Portuguese type familial amyloid polyneuropathy is a dominantly inherited neuropathic amyloidosis caused by a mutant transthyretin (TTR). Because TTR is produced mainly by the liver, liver transplantation (LT) abolishes production of the amyloidogenic variant TTR. To date, the procedure appears to halt the progress of the disease. However, long-term outcome is unknown. The aim of the present study is to evaluate the survival of our initial group of unselected liver transplant recipients with FAP. Seventy patients, 51 transplant recipients and a control group of 19 nontransplantation patients, with disease onset before the age of 55 years were included on the study. Transplant recipients were divided into two categories: (1) early series, with patients followed up for 5 years or longer, and (2) new series, with patients followed up for 1 to 5 years. Nonparametric statistical methods were used. Binary regression analyses were performed by stepwise logistic regression and Cox proportional hazard regression. Survival analysis was performed using Kaplan-Meier analysis, the Cox-Mantel test. Survival analyses and Cox proportional hazard regression analysis were performed from disease onset, not from LT. Significantly decreased survival was noted for transplant recipients with a modified body mass index (mBMI) less than 600 compared with the control group (P < .05). A significant difference in survival also was observed between transplant recipients with an mBMI greater than 600 at the time of LT compared with those with an mBMI less than 600 (P < .02). mBMI and age at LT had a significant impact on survival; whereas late deaths were related to age at LT, early deaths were related to mBMI. The cumulative 10-year survival rate after disease onset was 94% in the new series, with one early death (< 6 months) after LT, compared with a 78% survival rate and eight early deaths in the early series (P = .1).  (+info)

Effect of the intestinal flora on amyloid deposition in a transgenic mouse model of familial amyloidotic polyneuropathy. (6/93)

Familial amyloidotic polyneuropathy (FAP) is a hereditary disease characterized by the systemic accumulation of amyloid fibrils. A mutant transthyretin (TTR) gene is mainly responsible for the disease. However, the variable age of onset and low penetrance might be due to environmental factors, one of which is the intestinal flora. Three types of intestinal flora were introduced into a transgenic (Tg) mouse FAP model, 6.0-hMet30. The CV1 and CV2 group transgenic mice were transferred with the intestinal flora from two different mouse facilities housed under conventional conditions, and the SPF group transgenic mice were kept under specific pathogen free conditions in our facility. All the mice were maintained under controlled temperature, humidity and bacterial conditions. Over a period of 28 months, amyloid was not deposited in the SPF and CV1 groups. In contrast, amyloid was deposited in the esophagus and small intestine of two of the three CV2 mice at 18 months. Many neutrophils infiltrated the lesions. The numbers of tissue neutrophils were higher in the CV2 group than in the SPF and CV1 groups at 18 months. The CV2 flora included fewer gram-positive anaerobic cocci as well as higher proportions of yeasts, staphylococci and enterobacteriaceae compared with the SPF and CV1 flora. These findings suggest that the intestinal flora plays an important role in amyloid deposition.  (+info)

Evidence for early cytotoxic aggregates in transgenic mice for human transthyretin Leu55Pro. (7/93)

Familial amyloidotic polyneuropathy (FAP) is a lethal autosomal dominant disorder characterized by systemic extracellular deposition of transthyretin (TTR) amyloid fibrils. Several groups have generated transgenic mice carrying human TTR Val30Met, the most common mutation in FAP. To study amyloidogenicity and cytotoxicity of different TTRs, we produced transgenic mice expressing human TTR Leu55Pro, one of the most aggressive FAP-related mutations. TTR deposition and presence of amyloid fibrils was investigated and compared to animals carrying the human TTR Val30Met gene kept under the same conditions. Deposition in a C57BL/6J background (TTR-Leu55Pro mice) and in a TTR-null background [TTR-Leu55Pro X TTR-knockout (KO) mice] was compared. Animals in a C57BL/6J background presented early (1 to 3 months) nonfibrillar TTR deposition but amyloid was absent. In a TTR-null background, presence of amyloid fibrils was detected starting at 4 to 8 months with a particular involvement of the gastrointestinal tract and skin. This data suggested that TTR homotetramers are more prone to fibril formation than TTR murine wild-type/human mutant heterotetramers. The nature of the deposited material was further investigated by immunocytochemistry. Both amorphous aggregates and small TTR fibrils were present in TTR-Leu55Pro X TTR-KO transgenics. We observed that these TTR deposits mimic the toxic effect of TTR deposits in FAP: animals with TTR deposition, present approximately twofold increased levels of nitrotyrosine in sites related to deposition. The TTR-Leu55Pro X TTR-KO mice here described are an important tool for the dual purpose of investigating factors involved in amyloidogenesis and in cytotoxicity of deposited TTR.  (+info)

Familial ATTR amyloidosis: microalbuminuria as a predictor of symptomatic disease and clinical nephropathy. (8/93)

BACKGROUND: Portuguese type familial amyloid polyneuropathy (FAP) is a neuropathic amyloidosis caused by a mutant transthyretin (TTR). Varying degrees of renal involvement have been reported. Our aim was to assess the value of microalbuminuria (MA) for predicting clinical neurological disease and overt nephropathy in TTR-related amyloidosis. METHODS: All subjects had the TTR Val30Met mutation, and were recruited between 1993 and 1999. We have prospectively evaluated 22 asymptomatic gene carriers (7 male, 15 female; mean age 41.6+/-9.6 years) and 32 patients with neuropathy (14 male, 18 female; 36.8+/-8.8 years, on average, 33.0+/-9.3 years at the onset of neuropathy). We measured urinary albumin excretion every year, if asymptomatic, or every 6 months if already affected. Kidney biopsies were performed in patients with normal urinary albumin excretion, MA, and overt nephropathy, respectively. RESULTS: In asymptomatic carriers, persistent MA was detected in eight (36%) subjects. The presence of MA in asymptomatic gene carriers, compared with those having normal urinary albumin excretion, conferred a 4.8-fold risk of developing neuropathy, usually within the subsequent 3 years. Once neurological signs appeared, nephropathy, manifested as MA, progressed to overt nephropathy in one-half of subjects. In patients with neuropathy, 24 (75%) had MA during follow-up: evolution towards clinical renal disease occurred in 14 (58%) and renal failure occurred in five (21%), always after a course of MA. Proteinuria or renal failure without prior persistent MA were never observed in the present patient cohort. Histopathological evaluation did not reveal glomerular lesions other than amyloid deposits to explain abnormal urinary albumin excretion. The amount of mesangial and vascular-pole amyloid deposits was correlated with the degree of albuminuria. CONCLUSIONS: Microalbuminuria represents the first stage of clinical TTR amyloid nephropathy and is premonitory of neuropathy. Its presence identifies a subgroup of patients who are more prone to develop overt nephropathy. Screening of MA may be important to assess disease onset and to recommend liver transplantation in individuals at risk.  (+info)

Hereditary transthyretin amyloidosis (ATTR amyloidosis) is a rare, genetically heterogenous, and clinically variable autosomal dominant disease that severely reduces life expectancy. As treatment options grow, a proper diagnostic approach is mandatory especially in non-endemic regions with diverse genetic backgrounds. We examined 102 neuropathy patients at a German neuromuscular centre. Common causes of polyneuropathy were ruled out by medical history and extensive laboratory testing to define a cohort of patients with progressive polyneuropathy classified as idiopathic. Molecular genetic testing of the entire TTR gene was performed, and the detected amyloidogenic and non-amyloidogenic variants were associated with the observed clinical phenotypes and results of prior diagnostic testing. Two of 102 patients tested positive for amyloidogenic mutations (p.Ile127Val and p.Glu81Lys), while a variant of unknown significance, p.Glu26Ser, was found in 10 cases. In both positive cases, previous negative biopsy
Background Hereditary transthyretin amyloid (ATTRm) amyloidosis is a systemic disease mainly affecting the peripheral nervous system and the heart. The disease is inherited in an autosomal dominant manner with a varying penetrance. It is caused by mutations in the transthyretin (TTR) gene. Today more than 100 disease causing mutations are known. The V30M mutation that is endemic in northern Sweden is the best studied and comprises the majority of the reported disease cases in the world. In ATTRm amyloidosis caused by the V30M mutation two distinct sub populations are seen, one with disease onset early in life and a mainly neuropathic disease and the other with late onset disease and both neuropathic disease and a progressive cardiomyopathy. These phenotypical findings have in Swedish patients been tied to differences in amyloid fibril composition. Generally, patients with early onset disease have amyloid fibrils containing only full length transthyretin (type B) whereas patients with late onset ...
Reduced amplitude of the ulnar motor nerve and the sural nerve action potentials may be specific to transthyretin familial amyloid polyneuropathies, allowing us to distinguish this disorder from other demyelinating polyneuropathies.
Liver transplantation (LT) is a potentially curative treatment for hereditary transthyretin amyloidosis, of which familial amyloid polyneuropathy (FAP) is the most common form in Sweden. This study investigated the long-term development in heart rate variability (HRV) after LT in Swedish FAP patients. HRV was analyzed before LT, and during a first (,40 months) and a second (,40 months) follow-up recording after transplantation, respectively. Power spectrum analysis was performed on 2-min sequences in the supine position and after passive tilt, after careful identification of patients with arrhythmia. Data were obtained from 33 patients, but 18 patients had developed cardiac arrhythmia or were pacemaker-treated (4 before LT and 14 after LT) and three patients had not performed the first follow-up recording. In the remaining 12 patients, HRV decreased between the pretransplant evaluation and the first follow-up, thereafter no significant changes were found. In conclusion, our study showed that the ...
163 patients (92 males), with a mean age of 41.04 ± 11.68 years [26-80] and a mean duration of disease of 29.66 ± 17.48 months [4-90], completed a 12M evaluation. Body mass index remained stable throughout these 12M (3.13 vs. 3.14, p,0.008).. Mean NIS score decreased from baseline to 12M (2.35 vs. 2.34, p,0.694, ns) and Norfolk score improved between baseline and 12M (3.03 vs. 2.74, p,0.000).. Responders (n=112, 68,7%) showed a significant NIS-score decrease between baseline and 12M (2.24 vs. 2.05, p,0.000). Non-responders showed a significant increase across one year (2.56 vs. 2.88, p,0.000). Nonetheless, even in this group there was a Norfolk decreased in the same period (3.27 vs. 3.06, p,0.020)..

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 ...

Transthyretin familial amyloid polyneuropathy (TTR-FAP) is a progressive, fatal, inherited disorder first identified in Portugal and now recognized in all continents. Over the past decade, thanks to the availability of the genetic test, our knowledge on the range of clinical expressions of this disorder has expanded, including different patterns and progression rates of the neuropathy, as well as aspects of the cardiomyopathy, which can be prominent. In the mean time, new tools are being developed to detect earlier TTR amyloid deposition such as cardiac scintigraphy with technetium-labelled pyrophosphate tracers or small nerve fiber alterations from skin biopsies, or using neurophysiological approaches as well as magnetic resonance neurography (MRN ...

Per Hammarstr�m, Frank Schneider, and Jeffery W. Kelly http://sageke.sciencemag.org/cgi/content/abstract/sageke;2001/2/or18 Abstract: Science 293, 2459-2462 (2001).. The transthyretin (TTR) amyloid diseases, representative of numerous misfolding disorders, are of considerable interest because there are mutations that cause or suppress disease. The Val30>Met30 (V30M) TTR mutation is the most prevalent cause of familial amyloid polyneuropathy in heterozygotes, whereas a Thr119>Met119 (T119M) mutation on the second TTR allele protects V30M carriers from disease. Here, we show that the incorporation of one or more T119M TTR subunits into a predominantly V30M tetramer strongly stabilized the mixed tetramer against dissociation. Dissociation is required for amyloid formation, so these findings provide a molecular explanation for intragenic trans-suppression of amyloidosis. The data also suggest a potential therapeutic strategy, provide insight into tissue-specific deposition and amyloid composition, ...

Val30Met mutation accounts for the majority of the patients with large endemic foci especially in Portugal, Sweden and Japan. However, more than one hundred other mutations have been described worldwide. A great phenotypic variability among patients with late- and early-onset has been reported. Objective: To present a detailed report of TTR-FAP patients diagnosed in our tertiary neuromuscular center, in a 20-year period. Methods: Clinical informations were gathered through the database of our center. …Results: The study involved 76 individuals carrying a TTR-FAP mutation. Three phenotypes were identified, each ...
OBJECTIVE: To systematically study peripheral nerve morphology in patients with transthyretin (TTR) amyloidosis and TTR gene mutation carriers using high-resolution ultrasonography (US). METHODS: In this prospective cross-sectional study we took a structured history, performed neurological examination, and measured peripheral nerve cross-sectional areas (CSAs) bilaterally at 28 standard locations using US. Demographic and US findings were compared to controls. RESULTS: Peripheral nerve CSAs were significantly larger in 33 patients with familial amyloid polyneuropathy (FAP) compared to 50 controls, most dramatically at the common entrapment sites (median nerve at the wrist, ulnar nerve at the elbow), and in the proximal nerve segments (median nerve in the upper arm, sciatic nerve in the thigh ...

Alnylams patisiran may soon become the standard of care in treating hereditary transthyretin amyloidosis in patients with widespread neuropathy.. In phase 3 trials, patisiran significantly reduced the progression of neuropathy and it improved patients quality of life. Specifically, 225 patients were enrolled in a study comparing patisiran to placebo. Patients were treated for 18 months and patients receiving patisiran experienced a highly significant reduction in neuropathy versus placebo, as measured by a composite neuropathy score, with a p-value of 0.00001. Patients also experienced an improvement in the quality of life as measured by a questionnaire.. Despite worry over safety risks associated with interfering with RNA, patisirans safety profile doesnt appear to raise a lot of eyebrows. The rate of adverse events in the patisiran and placebo arms was similar (96.6% and 97.4%, respectively), as was the rate of serious adverse events (36.5% and 40.3%, respectively).. ...

A 67-year-old man presented with neuropathy. Five years earlier he had undergone liver transplantation because of cirrhosis caused by hemochromatosis with multiple foci of hepatocellular carcinoma. The donor liver was procured from a patient with transthyretin-derived (ATTR) amyloidosis caused by a TTR mutation (p.Val71Ala). A fat-biopsy showed Congo red-positive amyloid deposits (Figure 1A) with green birefringence (Figure 1B). Two years after presentation (7 years after transplantation) bone scintigraphy with 99mTc-hydroxyethylene diphosphonate showed uptake in several soft tissues as well as the heart (Figure 2).1 Echocardiography at that time still showed normal left ventricular end-diastolic volume (74 mL/m2), normal left ventricular function (ejection fraction, 56%; global longitudinal systolic strain, 17.4%), normal wall thickness (interventricular septum, 10 mm; posterior wall, 10 mm; and right ventricular wall, 5 mm), normal diastolic function (septal e′ 10.4 cm/s and lateral e′ ...
The FDA approved Akcea Therapeutics Tegsedi (inotersen) for the treatment of polyneuropathy caused by hereditary transthyretin (hATTR)-mediated amyloidosis in adults. The self-administered RNA-targeting therapeutic was approved by European agencies three months ago.. Tegsedis approval has come shorty after the FDA clearance of Alnylam Pharmaceuticals Onpattro (patisiran) for the treatment of adults with polyneuropathy due to hATTR, marking the first drug authorized for this indication in the U.S.. While Akcea has currently priced Tegsedi at a similar level to Onpattro (around $345,000 to $450,000 a year), Akcea CEO Paul Soteropoulos commented that the company is considering strategies to increase affordability. She noted that its self-administration gives the flexibility to treat at a time that works for [patients], which could change the way this progressive and debilitating disease is treated and managed. Onpattro is administered via infusion at a clinic once every three weeks. Despite ...

The tetrameric thyroxine transport protein transthyretin (TTR) forms amyloid fibrils upon dissociation and monomer unfolding. The aggregation of TTR causes life-threatening transthyretin amyloidosis (ATTR) associated with three conditions traditionally known as senile systemic amyloidosis, familial amyloidotic polyneuropathy, and familial amyloidotic cardiomyopathy. Senile systemic amyloidosis is a late onset disease in which Tafamidis, a TTR tetramer stabilizer, has been recently approved in Europe; it delays progression of the disease. Several other therapeutics are currently in clinical trials, including other tetramer stabilizers such as diflunisal and RNAi therapies that cause a decrease in the production of TTR protein. Additional approaches are needed to prevent ATTR, and here we explore the use of peptide inhibitors that block aggregation of TTR. Several models of the TTR amyloid spine have been proposed, but the aggregation-prone segments of the protein remain uncertain. Based on the ...
Transthyretin amyloidosis is caused by deposition of hepatocyte-derived transthyretin amyloid in peripheral nerves and heart. A paper recently published in the New England Journal of Medicine reports the safety and efficacy of a potent antitransthyretin small interfering RNA (RNAi) encapsulated in lipid nanoparticles and injected in patients with transthyretin amyloidosis. 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.. ...

The 44-year-old man in this study was presented with sudden-onset, persistent epigastralgia and had undergone living donor living transplantation (LDLT) for familial amyloid polyneuropathy at 42 years of age, with the left hepatic lobe graft donated by his wife. During LT, biliary reconstruction was performed by hepaticojejunostomy with a Roux limb via the antecolic route as the common bile duct was removed for the sake of the following domino LT. The peritoneal defect related to Roux-en-Y anastomosis was primarily closed with several 4-0 silk interrupted sutures. Although he had experienced repeated episodes of small bowel obstruction, which had all recovered fully following conservative management, at 5, 9, and 14 months post-transplantation, continuous epigastralgia and repeated vomiting for 7 h during the present admission prompted clinical suspicion of bowel strangulation. Abdominal guarding and rigidity in the epigastric region were noted on examination. The body temperature was 37.1 °C. ...

In the present study, we found complete defects on MIBG myocardial scans in 8 of 12 patients and limited uptake in the remaining 4 in association with severe systemic autonomic dysfunction. The incidence and magnitude of myocardial accumulation of MIBG were independent of clinical findings, including neurologic disabilities, duration of the illness, extent of endomyocardial amyloid deposition, ECG QRS voltage and ventricular wall thickness. These findings strongly suggest that cardiac adrenergic denervation due to autonomic nervous degeneration ([28]) accounts for alterations in I-123 MIBG myocardial imaging in patients with familial amyloid polyneuropathy. The presence of small localized concentrations of MIBG in the LV anterior wall in some patients indicates that myocardial sympathetic innervation is not equally impaired in this disease.. As we have previously reported ([34]), Tc-99m PYP scintigraphy may have the potential to detect early myocardial amyloid infiltration in patients with ...
Familial transthyretin amyloid polyneuropathy. Curator: Larry H. Bernstein, MD, FCAP. LPBI. First-Ever Evidence that Patisiran Reduces Pathogenic, Misfolded TTR Monomers and Oligomers in FAP Patients. We reported data from our ongoing Phase 2 open-label extension (OLE) study of patisiran, an investigational RNAi therapeutic targeting transthyretin (TTR) for the treatment of TTR-mediated amyloidosis (ATTR amyloidosis) patients with familial amyloidotic polyneuropathy (FAP). Alnylam scientists and collaborators from The Scripps Research Institute and Misfolding Diagnostics, Inc. were able to measure the effects of patisiran on pathogenic, misfolded TTR monomers and oligomers in FAP patients. Results showed a rapid and sustained reduction in serum non-native conformations of TTR (NNTTR) of approximately 90%. Since NNTTR is pathogenic in ATTR amyloidosis and the level of NNTTR reduction correlated with total TTR knockdown, these results provide direct mechanistic evidence supporting the therapeutic ...
Wild-type transthyretin amyloid (WTTA), also known as senile systemic amyloidosis (SSA) and abbreviated as ATTR, is a disease that typically affects the heart and tendons of elderly people. It is caused by accumulation of a wild-type (that is to say a normal) protein called transthyretin. This is in contrast to a related condition called transthyretin-related hereditary amyloidosis where a genetically mutated transthyretin protein tends to deposit at a much earlier age than in WTTA, due to abnormal conformation and bioprocessing. It belongs to a group of diseases called amyloidosis, chronic progressive conditions linked to abnormal deposition of normal or abnormal proteins, because these proteins are misshapen and cannot be properly degraded and eliminated by the cell metabolism. Wild-type transthyretin amyloid accumulates mainly in the heart, where it causes stiffness and often thickening of its walls, leading consequently to shortness of breath and intolerance to exercise, called diastolic ...
Results We found amyloid deposition in 13 of our 30 domino liver recipients. A Kaplan-Meier analysis estimated that the median time from DLT to the first detection of amyloid was 8.5 years. In the literature review, the mean time was 7.3 years, with a wide range of 0.5-13 years. Our 7 symptomatic cases and the literature cases with acquired ATTR amyloidosis presented with clinical features that differed from patients with ATTRv amyloidosis who were the domino liver donors. Patients with acquired ATTR amyloidosis showed markedly milder autonomic disturbance, which is one of the main symptoms of ATTRv amyloidosis. ...
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 ...

RESULTS. 3 patients received a domino graft (from a donor transplanted for familial amyloidotic polyneuropathy); 2 a living related donor graft and 2 a cdaver graft. 5 of the 7 are alive, and as the presenter said 4 are alive and well, but post transplant experience can have complications which are described below. The average followup time for these patients is 12.8 months (4-30 months). The longest a patient is alive who is doing well is 30 months. In general transplant experience is that patients with hepatitis B have better outcomes than patients with hepatitis C. 3 patients are doing relatively well. The study presenter said 4 of the 7 patients have shown dramatic improvement. 1 patient is in good condition at month 30 and is HCV negative. a second patient has F1 fibrosis at month 12 of followup with low or undetectable HIV RNA and in good condition. A third patient is in good condition at month 18 of followup. Three patients are not doing well. Another patient is alive with F3 fibrosis ...
Background. Liver transplantation (LTx) is an accepted treatment for hereditary transthyretin (TTR) amyloidosis (ATTR). However, unforeseen heart complications, especially a rapid development of cardiomyopathy after LTx has affected mortality and morbidity. Recently, a relationship between ATTR-fibril composition and cardiomyopathy has been noted. The aim of this study was to investigate whether development of cardiomyopathy and heart failure in LTx ATTR amyloid patients is related to amyloid fibril composition.. Methods. Twenty-four patients with hereditary ATTR amyloidosis who had undergone LTx and have had their amyloid fibril type tested were available for the study. They had been examined by echocardiography including tissue Doppler and speckle tracking echocardiography before and after LTx. Patients were divided into two groups according to fibril composition, 10 patients with type A fibrils (a mixture of truncated and full-length TTR) and 14 patients with type B fibrils (full-length TTR ...
Misfolding of the protein encoded by the transthyretin (TTR) gene, resulting in long fibrils of amyloid protein, has been implicated in a variety of diseases, ranging from amyloid transthyretin amyloidosis to cardiovascular disease. We aim to assess the ability of mutations known to stabilize the TTR protein to protect against these diseases, or to confer prolonged survival for them. We also will examine other mutations known to impact TTR expression levels and function.. While there are contradictory studies of one of these mutations, these studies did not use exactly the same analytical methods. We aim to use the same analytical methods, and also to subset to the higher risk older populations within the data, to get a more complete picture of how stabilizing TTR mutations affect risk of TTR-related diseases. We will test if people with these putatively protective mutations are less likely to develop TTR-related diseases, and if people with these mutations who do develop these diseases have ...

Fifty years ago, the focus on the Val30Met type of the disease, in which neurologic manifestations predominate, led to the widespread notion that hereditary transthyretin-related amyloidosis (ATTR) was essentially a neurologic disease. It is now clear that ATTR is extremely heterogeneous on both genotypic and phenotypic grounds. The clinical spectrum of the disease ranges from an almost exclusive neurologic involvement to strictly cardiac manifestations. This heterogeneity is linked to several factors including specific transthyretin mutations, geographic distribution and endemic vs. non-endemic aggregation type. The existence of exclusively or predominantly cardiac phenotypes makes the recognition of the disease very challenging since it can mimic other more common causes of left ventricular hypertrophy. Assessment of such patients should include an active search for possible red flags that can indicate the correct final diagnosis. More in general the clinician must be aware that: ...

The sec_rgy_attr_test_and_update() routine updates an attribute only if the set of control attributes specified in the test_attrs match attributes that already exist for the object. This update is an atomic operation: if any of the control attributes do not match existing attributes, none of the updates are performed, and if an update should be performed, but the write cannot occur for whatever reason to any member of the update_attrs array, all updates are aborted. The attribute causing the update to fail is identified in failure_index. If the failure cannot be attributed to a given attribute, failure_index contains -1. If an attribute instance already exists which is identical in both attr_id and attr_value to an attribute specified in in_attrs, the existing attribute information is overwritten by the new information. For multi-valued attributes, every instance with the same attr_id is overwritten with the supplied values. If an attribute instance does not exist, it is created. If you specify ...
