Abstract
BACKGROUND Hereditary amyloid transthyretin amyloidosis with polyneuropathy (ATTRv-PN) is a rare, inherited, multisystemic, progressive adult-onset disease, affecting sensorimotor nerves, and various organs. It is caused by mutations in the TTR gene, leading to misfolded monomers that aggregate, forming amyloid fibrils. Patisiran is a small, double-stranded interfering RNA encapsulated in a lipid nanoparticle, designed to enter hepatocytes and selectively target TTR mRNA to reduce both variant TTR and wild-type TTR (wt). This study presents a multicenter, real-life experience of patisiran's effectiveness and safety in ATTRv-PN. METHODS We enrolled genetically confirmed ATTRv-PN patients from 29 specialized Italian centers. All subjects underwent neurological assessments, including familial amyloid polyneuropathy (FAP) staging, the Neuropathy Impairment Score (NIS), quality-of-life assessment using the Norfolk Quality of Life-Diabetic Neuropathy (Norfolk QOL-DN) questionnaire, and the Compound Autonomic Dysfunction Test (CADT). Additional assessments included baseline and follow-up measures of serum NT-proBNP and interventricular septal thickness. RESULTS A total of 181 ATTRv patients (69% male) were enrolled. Neurological onset was reported in 60.2% of cases. At baseline, 83.4% of patients exhibited multisystemic involvement, while only 16.6% presented isolated polyneuropathy. For approximately 70% of patients, patisiran was the first treatment; the remainder transitioned from tafamidis or inotersen. Following treatment, most patients demonstrated stabilization of neuropathy progression, regardless of baseline disease severity or genotype. The treatment was well-tolerated, with 90% of patients reporting no adverse events. CONCLUSION Patisiran can be considered a valid therapeutic option for the management of patients with ATTRv amyloidosis. Considering its mechanism of action, similar outcomes could also be expected with the wider utilization of newly approved gene silencers for ATTRv therapy, such as vutrisiran.

Abstract
Introduction. Hereditary transthyretin amyloidosis (hATTR) is a rare disorder with a largely variable worldwide prevalence, and it is caused by autosomal dominant mutations in the transthyretin (TTR) gene, leading to cardiological, neurological, or mixed phenotypes. Apart from the Glu89Gln, Phe64Leu, and Thr49Ala variants, recently, other mutations of TTR gene have been reported in Sicily (His90Asn, Val122Ile, Ser77Phe, Val20Ala). With this paper, we describe a novel mutation in the TTR gene, the Glu61Ala variant, which had been previously reported in only one case with a cardiac phenotype, and the clinical findings surrounding it. Materials and Methods. One individual affected by chronic idiopathic polyneuropathy and a major red flag for hATTR underwent genetic testing to look for mutations in the TTR gene. Then, his relatives were subjected to the same test. We assessed the anamnestic profile and conducted general and neurological examination, blood tests, nerve conduction studies (NCS), electrocardiogram, and Sudoscan for each patient. Written informed consent was acquired for every patient. Results. Among 7 patients screened, 5 patients carried the Glu61Ala variant (71%). The mean age was 64.6 ± 10.2 years, whereas the mean age at onset was 59.4 ± 7.9 years. In our study, three patients (60%) showed a mixed phenotype, whereas two of them (40%) showed a neurological phenotype. Discussion. The Glu61Ala variant was reported only in one case with a cardiological phenotype, but our patients showed both neurological and cardiological involvement. Further studies are needed to improve knowledge of this genetic variant.

Abstract
We report the case of a 27-year-old man with transthyretin amyloidosis secondary to the p.Val142Ile mutation with an atypical clinical presentation of predominantly lower limb polyneuropathy without cardiac involvement. p.Val142Ile is mainly associated with cardiopathy, whereas the neuropathic phenotype is mainly associated with p.Val50Met. Our patient belongs to a non-endemic region and due to his lack of support network a possible familial component is unknown. His case represents a diagnostic challenge given the wide heterogeneity of clinical manifestations associated with the disease, with other possible diagnoses of polyneuropathy being reasonably excluded according to prevalence and frequency. The particularly unusual genotype-phenotype association distinguishes this case from the classic description of transthyretin amyloidosis secondary to p.Val142Ile.

Abstract
OBJECTIVES Although expert consensus recommendations suggest 2-3 h as the time interval between bone-seeking radiotracers injection and acquisition, it has been reported that images obtained early after [99mTc]Tc-HMDP administration are sufficient to diagnose cardiac amyloidosis. We evaluated the diagnostic performance of [99mTc]Tc-DPD early phase whole body scan with respect to late phase imaging. METHODS We qualitatively and semiquantitatively reviewed [99mTc]Tc-DPD imaging of 53 patients referred for suspect cardiac amyloidosis. Findings of early and late phase images were compared with SPECT results (considered the standard-of-reference) determining sensitivity and specificity for visual analysis of each phase imaging and for each semiquantitative index. RESULTS SPECT imaging was negative for cardiac accumulation in 25 patients and positive in 28. Visual analysis of early phase whole body scan had an extremely significant capability to predict SPECT results; nevertheless, complete agreement was not reached. Visual analysis of late phase imaging showed slightly better results. Semiquantitative analysis of early phase images, namely heart to mediastinum ratio, performed better than semiquantitative analysis of late phase images. CONCLUSION Visual analysis of [99mTc]Tc-DPD early phase whole body scan is promising in diagnosing cardiac amyloidosis; further studies are needed to confirm our results in different clinical scenarios. KEY POINTS • Visual analysis of early phase planar imaging using [99mTc]Tc-DPD is accurate to diagnose cardiac amyloidosis and may be satisfactory at least in frail patients with high cardiac burden of amyloid fibrils.

Abstract
INTRODUCTION Transthyretin amyloidosis (ATTR amyloidosis) is a progressive, clinically heterogeneous disease with spontaneous (wild-type) and hereditary (ATTRv) forms. The Glu89Gln variant is primarily associated with cardiomyopathy and prevalent in Italy and Bulgaria. The objective of this analysis was to better understand the profile of patients with ATTRv Glu89Gln amyloidosis in the Transthyretin Amyloidosis Outcomes Survey (THAOS). METHODS THAOS is an ongoing, global, longitudinal, observational survey of patients with ATTR amyloidosis, including both inherited and wild-type disease, and asymptomatic carriers with mutations in the transthyretin gene. Demographic and clinical characteristics of all symptomatic patients with the ATTRv Glu89Gln variant enrolled in THAOS are described (data cutoff, January 6, 2020). RESULTS There were 91 patients with ATTRv Glu89Gln amyloidosis with the majority from Bulgaria (n = 53) or Italy (n = 29). All patients were Caucasian and 50.5% were male. Patients from Bulgaria had a mean (standard deviation) age at enrollment of 57.1 (8.2) years, and duration of symptoms of 8.6 (9.6) years, compared with 54.8 (8.6) and 5.0 (4.1) years in Italy. In Bulgaria, 39.6% of patients were of a predominantly cardiac phenotype, 18.9% predominantly neurologic, and 41.5% mixed. In Italy, 3.4% of patients were predominantly cardiac, 62.1% predominantly neurologic, and 34.5% mixed. CONCLUSIONS The majority of patients with ATTRv Glu89Gln amyloidosis in THAOS are from Bulgaria or Italy. There were notable phenotypic differences, with the cardiac phenotype more common in Bulgaria and the neurologic phenotype more common in Italy. Over one-third of patients had a mixed phenotype, suggesting a potential role of multiple genetic and/or environmental factors and the need for comprehensive assessment of all patients.

Abstract
Case Presentarion:
Hereditary transthyretin amyloidosis is a progressive, fatal disease that generally involves the peripheral nervous system, the autonomic nervous system, and the heart. It is autosomal dominant with different penetrance depending on the mutation and the genetic background. Many other missense mutations of the TTR gene may cause the disease. Being an overall rare disease is very rare to observe the condition of homozygosity. In particular, cases of homozygosity have been described in patients with ATTRV30M and ATTRV122I amyloidosis. In the former, the phenotype does not seem to be aggravated, having an age of onset and disease course that does not appear to differ from those of heterozygotes, while in the latter, the onset appears to be earlier.
Conclusion:
We report the first case of ATTRE89Q amyloidosis in a patient that was homozygous for the E89Q mutation in the TTR gene. The clinical phenotype resulted in the earlier disease onset reported in this form of amyloidosis, suggesting that the homozygous condition may be prognostically negative.

Abstract
Background: Over the past decade, three new drugs have been approved for the treatment of hereditary amyloid transthyretin (ATTRv) polyneuropathy. The aim of this work was to analyze whether current therapies prolong survival for patients affected by ATTRv amyloidosis. Methods: The study was conducted retrospectively, analyzing the medical records of 105 patients with genetic diagnoses of familial amyloidotic polyneuropathy followed at the two referral centers for the disease in Sicily, Italy. Of these, 71 received disease-modifying therapy, while 34 received only symptomatic treatment or no therapy. Results: The most used treatment in our patient cohort was tafamidis, followed by liver transplantation, patisiran, inotersen, and diflunisal. The median survival was significantly longer for treated vs. untreated patients (12 years vs. 8 years). In the 71 patients who received disease-modifying treatment, the presence of cardiac involvement, weight loss, or autonomic dysfunction at diagnosis was not related to survival. Conversely, patients diagnosed in the early stage of the disease (PND 1) had significantly longer survival than those diagnosed in the late stage (PND 2–4).

Abstract
Hereditary amyloidosis associated with mutations in the transthyretin gene (hATTR) is a progressive devastating disease, with a fatal outcome occurring within 10years after onset. In recent years, TTR gene silencing therapy appeared as a promising therapeutic strategy, showing evidence that disease progression can be slowed and perhaps reversed. We report here 18 subjects affected by hATTR amyloidosis treated with patisiran, a small interfering RNA acting as TTR silencer, and evaluated with a PND score, the NIS and NIS-LL scale, and a Norfolk QOL-DN questionnaire at baseline and then every 6 months. A global clinical stabilizationwas observed for the majority of the patients, with mild-moderate improvements in some cases, even in advanced disease stage (PND score > 2). Analysis of NIS, NIS-LL and Norfolk QOL-DN results, and PND score variation suggest the possible presence of a 6-month latency period prior to benefit of treatment.

Abstract
Hereditary transthyretin-mediated (hATTR) amyloidosis is a progressive disease caused by mutations in the TTR gene leading to multisystem organ dysfunction. Pathogenic TTR aggregation, misfolding, and fibrillization lead to deposition of amyloid in multiple body organs and frequently involve the peripheral nerve system and the heart. Common neurologic manifestations include: sensorimotor polyneuropathy (PN), autonomic neuropathy, small-fiber PN, and carpal tunnel syndrome. Many patients have significant progression due to diagnostic delays as hATTR PN is not considered within the differential diagnosis. Recently, two effective novel disease-modifying therapies, inotersen and patisiran, were approved by Health Canada for the treatment of hATTR PN. Early diagnosis is crucial for the timely introduction of these disease-modifying treatments that reduce impairments, improve quality of life, and extend survival. In this guideline, we aim to improve awareness and outcomes of hATTR PN by making recommendations directed to the diagnosis, monitoring, and treatment in Canada.

Abstract
Hereditary amyloid transthyretin (ATTRv) amyloidosis with polyneuropathy is a progressive disease that is transmitted as an autosomal dominant trait and characterized by multiple organ failure, including axonal sensory-motor neuropathy, cardiac involvement, and autonomic dysfunction. Liver transplantation (LT) and combined heart-liver transplantation, introduced in the 1990s, have been the only therapies for almost two decades. In 2011, tafamidis meglumine became the first specific drug approved by regulatory agencies, since then the attention toward this disease has progressively increased and several drugs with different mechanisms of action are now available. This review describes the drugs already on the market, those that have shown interesting results although not yet approved, and those currently being tested.

Abstract
INTRODUCTION ATTRv amyloidosis is worldwide spread with endemic foci in Portugal and Sweden, Japan, Brazil, Maiorca, and Cyprus. A national Registry was developed to characterise the epidemiology and genotype-phenotype correlation of ATTRv amyloidosis in Italy and to allow a better planning of diagnostic and therapeutic services. METHODS Fifteen Italian referral centres for amyloidosis spread all over the country have contributed to the Registry. RESULTS Four-hundred-forty-seven subjects were enrolled, 187 asymptomatic carriers and 260 affected patients. Thirty-one different mutations were recorded. The seven most represented genetic variants were significantly different in terms of age at onset, clinical features and geographical distribution. National prevalence is 4.33/million with higher values in Southern Italy. Overall symptoms of polyneuropathy were present at disease onset in about half of the patients, symptoms of cardiomyopathy in a quarter of patients, the rest referring carpal tunnel syndrome, dysautonomia or lumbar spinal stenosis. 52.6% of patients were in FAP stage 1, 20.4% in stage 2 and 13.5% in stage 3, while 13.5% patients had no neuropathy, presenting only cardiological symptoms. CONCLUSIONS We presented an epidemiological study based on collaboration among referral centres for ATTRv amyloidosis spread in all the Italian territory, using web-based Registry. It provided a detailed map of the regional distribution of the disease. The increased awareness of the disease among general practitioners and medical specialists has contributed to reduce the diagnostic delay and the rate of misdiagnosis. The Registry will allow to collect also future information about clinical and instrumental follow-up.

Description of a large cohort of Caucasian patients with V122I ATTRv amyloidosis: Neurological and cardiological features. J Peripher Nerv Syst 2020; 25:273-278. [PMID: 32395865 DOI: 10.1111/jns.12385] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2020] [Revised: 05/08/2020] [Accepted: 05/08/2020] [Indexed: 01/19/2023]
Abstract
V122I is one of more than 130 mutations in transthyretin gene associated with hereditary TTR (ATTRv) amyloidosis. Main clinical expression is an infiltrative pseudohypertrophic cardiomyopathy with mild or no neurological symptoms. It is particularly common among African-Americans (prevalence: 3%-4%). We report 12 subjects from seven unrelated Caucasian families hailing from Sicily and carrying the V122I mutation. One patient was homozygous for V122I and in another family two subjects also carried the E89Q variant in compound heterozygosity. All the subjects underwent neurologic/neurophysiologic evaluation and cardiologic baseline tests; in five of them, cardiac magnetic resonance and/or (99 m) Tc-DPD scintigraphy were performed. Three of 12 subjects were asymptomatic carriers. Of the remaining nine subjects, in four of nine patients, the nerve conduction studies revealed a polyneuropathy; in one of them, this represents the only sign of disease after 5 years of follow-up. In eight of nine subjects, we found a hypertrophic restrictive cardiomyopathy and cardiac failure, associated with a carpal tunnel syndrome. Although in non-Afro-American individuals V122I prevalence is low, subjects carrying this mutation have been identified in the United Kingdom, Italy, and France. Our report describes a large cohort of V122I Caucasian patients from a non-endemic area, confirming the possible underestimation of this mutation in the non-African population. Moreover, it highlights the heterogeneity in the genotype-phenotype correlation of ATTRv mutations, suggesting that the presence of a polyneuropathy has to be identified as soon as possible, since available treatments are, in Europe, so far authorized only for ATTRv amyloid peripheral neuropathy.

Abstract
We report a 73-year-old man with Val142Ile transthyretin (TTR) amyloidosis and an atypical clinical presentation of upper-extremity-predominant neuropathy without significant autonomic or cardiac involvement. TTR familial amyloid polyneuropathy commonly presents as length-dependent sensorimotor polyneuropathy with marked and early autonomic involvement. Multiple pathogenic mutations in TTR gene have been identified, of which Val50Met is commonly associated with TTR familial amyloid polyneuropathy, and Val142Ile is commonly associated with familial amyloid cardiomyopathy. Our patient is from a nonendemic region, without family history for amyloidosis. Predominant upper-extremity neuropathy, without significant cardiac or autonomic involvement, distinguishes this case from previously reported Val142Ile-mutated TTR amyloidosis.

Abstract
PURPOSE OF REVIEW The aim is to provide a description of the most important echocardiographic features in systemic amyloidosis. RECENT FINDINGS Amyloidosis is a heterogeneous group of multisystem disorders, characterized by an extracellular deposition of amyloid fibrils. Several imaging tests are available for the diagnosis; however, echocardiography is the cornerstone of the non-invasive imaging modality for cardiac amyloidosis. So far, little is known about the diagnosis of cardiac amyloidosis through imaging modalities. We summarized the most important echocardiographic findings in cardiac amyloidosis. Hence, we offered a systematic report of the diagnostic performance of cardiac amyloidosis using echocardiography.
