Clinical and genetic profiles of patients with hereditary and wild type transthyretin amyloidosis: the transthyretin cardiac amyloidosis registry in the state of Sao Paulo, Brazil REACT-SP

Eur. heart j; 45 (Suppl. 1), 2024
INTRODUCTION: Transthyretin amyloidosis (ATTR) is a multisystem disease caused by the deposition of fibrillar protein in organs and tissues. ATTR genotypes and phenotypes are highly heterogeneous. PURPOSE: We designed the Transthyretin Cardiac Amyloidosis Registry in the state of São Paulo (REACT-SP), a...

Clinical and laboratorial profile of patients with ATTR cardiomyopathy: comparison between wild type and pVal142Ile forms in the Brazilian population

Eur. heart j; 45 (Suppl. 1), 2024
BACKGROUND: In Brazil, besides the wild type (wt) form, transthyretin amyloid cardiomyopathy (ATTR-CM) is predominantly caused by hereditary form with Val142Ile mutation. Considering that both forms occur in elderly people, the clinical presentation may be similar. We sought to compare the clinical prese...

Amiloidose por transtirretina na segunda década de vida: um raro diagnóstico diferencial em jovens
Transthyretin amyloidosis in the second decade of life: a rare differential diagnosis in young people

Arq. bras. cardiol; 121 (9 supl.1), 2024
INTRODUÇÃO: Sendo p.V50M e p.V142I as variantes mais comuns associadas à amiloidose por transtirretina hereditária (ATTRh), pode haver uma errônea correlação de que a doença se manifeste apenas em idosos já que a apresentação clínica em seus portadores geralmente se inicia tardiamente, em mei...

Clinical and genetic profiles of patients with hereditary and wild-type transthyretin amyloidosis: the transthyretin cardiac amyloidosis registry in the state of São Paulo, Brazil (REACT-SP)

Orphanet j. rare dis; 19 (1), 2024
BACKGROUND: Transthyretin amyloidosis (ATTR) is a multisystem disease caused by the deposition of fibrillar protein in organs and tissues. ATTR genotypes and phenotypes are highly heterogeneous.

Perfis clínicos e genéticos de pacientes com amiloidose transtiretina hereditária e do tipo selvagem: o registro de amiloidose cardíaca transtiretina no Estado de São Paulo, Brasil (REACT-SP)
Clinical and genetic profiles of patients with hereditary and wild-type transthyretin amyloidosis: the transthyretin cardiac amyloidosis registry in the State of São Paulo, Brazil (REACT-SP)

Int. j. cardiovasc. sci. (Impr.); 37 (suppl.1), 2024
INTRODUÇÃO: A amiloidose transtiretina (ATTR) é uma doença multissistêmica causada pela deposição de proteína fibrilar em órgãos e tecidos. Os genótipos e fenótipos da ATTR são altamente heterogêneos. MÉTODOS: Apresentamos dados sobre sinais e sintomas físicos, avaliações cardíacas e n...

Assessment of potential transthyretin amyloid cardiomyopathy cases in the Brazilian public health system using a machine learning mode

PLos ONE; 19 (2), 2024
OBJECTIVES: To identify and describe the profile of potential transthyretin cardiac amyloidosis (ATTR-CM) cases in the Brazilian public health system (SUS), using a predictive machine learning (ML) model. METHODS: This was a retrospective descriptive database study that aimed to estimate the frequency of...

Impact of patisiran on health status and quality of life in patients with transthyretin cardiac amyloidosis

J. card. fail; 30 (1), 2024
INTRODUCTION APOLLO-B is a Phase 3 study of patisiran in patients with transthyretin (ATTR) cardiac amyloidosis (NCT03997383), which demonstrated a significant benefit in functional capacity (6-MWT), and health status and quality of life (QoL) (KCCQ-OS) with patisiran vs placebo at Month (M) 12. HYPOTHES...

Using machine learning to assess potential cases of transthyretin cardiac amyloidosis in Brazil: a retrospective database approach

Value health; 26 (12 suppl), 2023
INTRODUCTION: Amyloidosis is a group of protein misfolding disorders leading to organ damage due to insoluble amyloid fibril deposits • The two primary types of cardiac amyloidosis are light-chain amyloid (AL) and transthyretin (TTR) cardiac amyloidosis • TTR amyloidosis can be hereditary (hATTR) or ...

World heart federation consensus on Transthyretin Amyloidosis Cardiomyopathy (ATTR-CM)

Glob. heart (Online); 18 (1), 2023
Transthyretin amyloid cardiomyopathy (ATTR-CM) is a progressive and fatal condition that requires early diagnosis, management, and specific treatment. The availability of new disease-modifying therapies has made successful treatment a reality. Transthyretin amyloid cardiomyopathy can be either age-relate...

Amiloidose cardíaca por transtirretina: mais de uma variante patogênica confere maior gravidade?
Transthyretin cardiac amyloidosis: does more than one pathogenic variant confer greater severity?

INTRODUÇÃO: Mais de 130 variantes patogênicas no gene TTR foram associadas à amiloidose por transtirretina hereditária (ATTRh), conferindo uma ampla heterogeneidade fenotípica nos indivíduos afetados, com início da doença variável e formas de apresentação distintas. Sendo ATTRh de herança au...
