Adherencia de pacientes de alto riesgo heredo-familiar de cáncer de mama a "Programa de Vigilancia Activa": experiencia de la Clínica de Alto Riesgo de Cáncer de Mama del Centro Mamario del Hospital Universitario Austral / Adherence of patients with high hereditary-familial risk of breast cancer to the "Active Surveillance Program": experience of the High Risk Breast Cancer Clinic of the Breast Center of the Austral University Hospital

Introducción: Las mujeres con predisposición genética-familiar presentan un riesgo más elevado de desarrollar cáncer de mama. La vigilancia es una de las estrategias más efectivas para ofrecer a este subgrupo de mujeres, sin embargo la adherencia a la misma puede ser dificultosa. Objetivo: Analizar la adherencia de las pacientes con Alto Riesgo Heredo-Familiar (ARHF) al programa específico de "Seguimiento de pacientes de Alto Riesgo" del Hospital Universitario Austral. Material y método: Se revisaron de forma retrospectiva datos de 104 mujeres sanas con ARHF que ingresaron al programa de vigilancia: "Seguimiento de pacientes de Alto Riesgo" del Hospital Universitario Austral en el período comprendido entre junio de 2016 a febrero de 2022. Resultados: La adherencia al programa fue total en 38 pacientes (36,54%) y parcial en 42 (40,38%). Se observó falta de adherencia en 24 pacientes (23,07%). La causa más prevalente fue la incomodidad al realizar la resonancia (54,16%). Analizando la adherencia según el año de ingreso al programa se observa una caída significativa a partir del 3er año de seguimiento y solo 48,98% completaron la sexta ronda. Conclusiones: La falta de adherencia observada fue significativa. Los datos demostrados apuntan a una necesidad de continuar desarrollando estrategias que faciliten el seguimiento(AU)

Introduction: Women with a genetic-familial predisposition have a higher risk of developing breast cancer. Surveillance is one of the most effective strategies to offer this subgroup of women, however adherence to it can be difficult. Objetive: To analize the adherence of patients with High Risk of Familial-Hereditary (HRFH) breast cancer to a specific program: "Follow-up in High Risk patients" of the Austral University Hospital. Material and method: Data from 104 women with HRFH who were admitted to the surveillance program: "Follow-up in High Risk patients" of the Austral University Hospital in the period from june 2016 to february 2022 were retrospectively reviewed. Results: Adherence to the program was complete in 38 patients (36,54%) and partial in 42 (40,38%). 24 (23,07%) patients had lack of adherence. The most prevalent cause was discomfort when performing the resonance (54,16%). When we analyze adherence according to the year of admission to the program, a significant drop is observed from de 3rd year of follow-up and only 48,98% completed round six. Conclusions: The observed lack of adherence was significant. The demonstrated data points to a need to continue developing strategies that facilitate monitoring(AU)

Avaliação Cintilográfica e Ecocardiográfica em Portadores de Variantes Patogênicas ou Provavelmente Patogênicas do Gene TTR sem Envolvimento Cardíaco Manifesto / Scintigraphic and Echocardiographic Study of Patients with Pathogenic or Probably Pathogenic Variants of the TTR Gene without Overt Cardiac Involvement

Resumo Fundamento: A amiloidose por transtirretina (ATTR) é uma doença infiltrativa causada pela deposição anormal de proteína principalmente no coração e no sistema nervoso periférico. Quando acomete o coração, a doença manifesta-se como uma cardiomiopatia restritiva e, quando afeta o sistema nervoso periférico e autônomo, apresenta-se como uma polineuropatia, podendo ser chamada de Polineuropatia Amiloidótica Familiar (PAF). Existem dois subtipos de ATTR, a ATTR selvagem, em que não há variantes genéticas, e a ATTR hereditária, caracterizada por uma variante no gene que codifica a proteína transtirretina (T/TR). Em ambos os subtipos, o envolvimento cardíaco é o principal marcador prognóstico. Objetivos: Avaliar a prevalência do envolvimento cardíaco subclínico em uma amostra de pacientes com variantes genéticas no gene TTR usando a cintilografia com pirofosfato e o ecocardiograma com strain; comparar os achados cintilográficos e as medidas de strain; avaliar a associação entre PAF e o envolvimento subclínico; e analisar se existe uma associação entre uma variante genética específica e o envolvimento cardíaco. Métodos: Estudo transversal com carreadores de variantes no gene TTR sem sintomas cardiovasculares e sem alterações nos parâmetros da eletrocardiografia ou do ecocardiograma convencional. Todos os pacientes foram submetidos à cintilografia com pirofosfato e à ecocardiografia com análise de strain. O envolvimento cardíaco subclínico, definido como um escore de Perugini ≥ 2, razão Coração (C)/ Hemitórax Contralateral (CL) ≥ 1,5 em uma hora, C/CL ≥ 1,3 na terceira hora, ou um strain longitudinal global (SGL) ≤ −17%. Realizadas análises descritiva e analítica, e aplicados o teste exato de Fisher e o teste de Mann-Whitney. Um valor de p<0,05 foi considerado significativo. Resultados: Os 23 pacientes avaliados apresentavam uma idade mediana de 51 (37-57) anos, 15 (65,2%) eram do sexo feminino, 12 (52,2%) eram pardos, nove (39,1%) apresentavam hipertensão arterial sistêmica, e nove (39,1%) tinham um diagnóstico prévio de PAF. Dos nove pacientes com PAF, oito (34,8%) usavam tafamidis. As variantes genéticas identificadas foram Val142IIe, Val50Met e IIe127Val. O valor mediano do SGL foi −19% (-16% - −20%). Dos 23 pacientes, nove (39,1%; 95% CI = 29-49%) preencheram os critérios de envolvimento cardíaco, seis (26%) somente pelo critério do SGL. Não houve associação entre PAF e um carreador assintomático avaliado por ecocardiograma com análise de strain e pela cintilografia com pirofostato (p=0,19). A prevalência de hipertensão arterial sistêmica, diabetes mellitus, dislipidemia, tabagismo e SGL reduzido não foi diferente entre os grupos. A velocidade da onda e' septal foi a única variável que apresentou diferença significativa entre os indivíduos com e sem SGL reduzido, com uma área sob a curva ROC de 0,80 (IC95% = 0,61-0,98, p = 0,027). A melhor acurácia diagnóstica foi alcançada com uma velocidade e' septal ≤ 8,5 cm/s. Não houve associação entre o tipo de variante genética e o envolvimento cardíaco pré-clínico, nem entre o uso de tafamidis e este mesmo envolvimento (37,5% versus 40,0%, p = 0,90). Conclusão: O envolvimento cardíaco subclínico foi frequente em uma amostra de carreadores da variante genética do gene TTR. Um valor do SGL reduzido foi o achado mais comum. Não houve associação entre a presença de polineuropatia amiloidótica e o envolvimento subclínico. O tipo de variante genética não foi associado com envolvimento cardíaco precoce. Nesta amostra, o uso de tafamidis (20mg/dia) não foi associado com uma menor prevalência de envolvimento cardíaco subclínico.

Abstract Background: Transthyretin amyloidosis (ATTR) is an infiltrative disease caused by abnormal protein deposition mainly in the heart and peripheral nervous system. When it affects the heart, the disease presents as restrictive cardiomyopathy; when it affects the peripheral and autonomic nervous system, it manifests as polyneuropathy, and is called familial amyloid polyneuropathy (FAP). There are two ATTR subtypes: wild-type ATTR, where there is no mutation, and mutant ATTR (ATTRm), which is characterized by a mutation in the gene encoding the transthyretin protein (TTR). In both subtypes, cardiac involvement is the major marker of poor prognosis. Objectives: To assess the prevalence of subclinical cardiac involvement in a sample of patients with TTR gene mutation by using pyrophosphate scintigraphy and strain echocardiography; to compare scintigraphy and strain findings; to evaluate the association between neurological manifestations (FAP) and subclinical cardiac involvement; and to analyze whether there is an association between any specific mutation and cardiac involvement. Methods: This is a cross-sectional study with carriers of the TTR gene mutation, without cardiovascular symptoms or changes in electrocardiographic or conventional echocardiographic parameters. All patients underwent pyrophosphate scintigraphy and strain echocardiography. Subclinical cardiac involvement was defined as a Perugini score ≥ 2, heart-to-contralateral lung (H/CL) ratio ≥ 1.5 at 1 h, H/CL ≥1.3 at 3 h, or global longitudinal strain (GLS) ≤ −17%. Descriptive and analytical analyses were performed and Fisher's exact test and Mann-Whitney test were applied. A value of p < 0.05 was considered significant. Results: The 23 patients evaluated had a median age of 51 years (IQR 37-57 years), 15 (65.2%) were female, 12 (52.2%) were Pardo, nine (39.1%) had systemic arterial hypertension, and nine (39.1%) had a previous diagnosis of FAP. Of the nine patients with FAP, 8 (34.8%) were on tafamidis. The associated mutations were Val142IIe, Val50Met, and IIe127Val. The median GLS in the sample was −19% (−16% to −20%). Of the 23 patients, nine (39.1%; 95% CI = 29-49%) met criteria for cardiac involvement, six (26%) by the GLS-based criteria only. There was no association between having FAP and being an asymptomatic carrier, as assessed by strain echocardiography and pyrophosphate scintigraphy (p = 0.19). The prevalence of systemic arterial hypertension, diabetes mellitus, dyslipidemia, smoking, and reduced GLS did not differ between groups. Septal e' wave velocity was the only variable that significantly differed between individuals with and without reduced GLS, with an area under the ROC curve of 0.80 (95% CI = 0.61-0.98, p = 0.027). The best diagnostic accuracy was achieved with a septal e' velocity ≤ 8.5 cm/s. There was no association between mutation type and preclinical cardiac involvement, nor between tafamidis use and lower degree of cardiac involvement (37.5% versus 40.0%, p = 0.90). Conclusion: Subclinical cardiac involvement was common in a sample of TTR mutation carriers without cardiac involvement. Reduced left ventricular GLS was the most frequent finding. There was no association between the presence of amyloid polyneuropathy and subclinical cardiac involvement. Type of mutation was not associated with early cardiac involvement. In this sample, the use of tafamidis 20 mg/day was not associated with a lower prevalence of subclinical cardiac involvement.

Real-life experience with inotersen at CEPARM, Hospital Universitário Clementino Fraga Filho, Universidade Federal do Rio de Janeiro / Experiência de vida-real com inotersena no CEPARM, Hospital Universitário Clementino Fraga Filho, Universidade Federal do Rio de Janeiro

Abstract Background Hereditary transthyretin amyloidosis (ATTRv) is an inherited, progressive, and fatal disease still largely underdiagnosed. Mutations in the transthyretin (TTR) gene cause the TTR protein to destabilize, misfold, aggregate, and deposit in body tissues, which makes ATTRv a disease with heterogeneous clinical phenotype. Objective To describe the long-term efficacy and safety of inotersen therapy in patients with ATTRv peripheral neuropathy (ATTRv-PN). Methods Patients who completed the NEURO-TTR pivotal study and the NEURO-TTR OLE open-label extension study migrated to the present study and were followed-up for at least 18 more months to an average of 67 months and up to 76 months since day 1 of the inotersen therapy (D1-first dose of inotersen). Disease progression was evaluated by standard measures. Results Ten ATTRv-PN patients with Val30Met mutation were included. The mean disease duration on D1 was of 3 years, and the mean age of the patients was of 46.8 years. During an additional 18-month follow up, neurological function, based on the Neuropathy Impairment Score and the Polyneuropathy Disability Score, functionality aspects (Karnofsky Performance Status), and nutritional and cardiac aspects were maintained. No new safety signs have been noted. Conclusion The treatment with inotersen was effective and well tolerated for the average of 67 months and up to 76 months. Our results are consistent with those of larger phase-III trials.

Resumo Antecedentes Amiloidose hereditária por transtirretina (ATTRv) é uma doença hereditária, progressiva e fatal ainda largamente subdiagnosticada. Mutações no gene transtirretina (TTR) promovem desestabilização, desdobramento, agregação e depósito da proteína TTR em tecidos do corpo, o que faz da ATTRv uma doença de fenótipo clínico heterogêneo. Objetivo Descrever a eficácia e segurança da terapia com inotersena no longo prazo em pacientes com neuropatia periférica ATTRv (ATTRv-PN). Métodos Pacientes que completaram o estudo pivotal NEURO-TTR e o estudo de extensão aberta NEURO-TTR OLE migraram para este estudo e foram acompanhados por no mínimo 18 meses adicionais, em média por 67 meses, e por até 76 meses, desde o dia 1 da terapia com inotersena (D1-primeira dose de inotersena). A progressão da doença foi avaliada por medidas padronizadas. Resultados Dez pacientes com ATTRv-PN com mutação Val30Met foram incluídos. A duração média da doença no D1 era de 3 anos, e a média de idade dos pacientes era de 46,8 anos. Durante o período de acompanhamento adicional de 18 meses, a função neurológica, baseada no Neuropathy Impairment Score e no Polyneuropathy Disability Score, os aspectos de funcionalidade (Karnofsky Performance Status), nutricional e cardíacos estavam mantidos. Não se observou nenhum novo sinal de segurança. Conclusão O tratamento com inotersena foi eficaz e bem tolerado por 67 meses em média, e por até 76 meses. Nossos resultados são consistentes com os de estudos maiores de fase III.

Considerations for Familial Chylomicronemia Diagnosis in the Era of Next-Generation Sequencing: A Latin American Perspective

Abstract Familial chylomicronemia syndrome (FCS) is an autosomal recessive disorder, characterized by alterations in the catabolism of chylomicrons and by increased levels of plasma triglycerides. It has been shown that about 60-90% of FCS patients have biallelic mutations in the LPL gene and the remaining patients have mutations in genes encoding proteins closely related to LPL function. The objective of this manuscript is to illustrate the different clinical scenarios of FCS presentation, and to guide practitioners on the usefulness of genetic tests in each of them. To this end, several published papers about recommendations for the diagnosis of FCS are discussed briefly, in addition to the presentation of several hypothetical cases, highlighting different clinical presentations and possible associated genetic findings. These cases illustrate the multiplicity of potential aspects of family history, clinical manifestations, biochemical parameters, and patterns of genetic variants found in genomic analyses of FCS.

Relationship between sacroiliitis and inflammatory markers in familial Mediterranean fever

SUMMARY OBJECTIVE: Familial Mediterranean fever is the most common monogenic autoinflammatory disease. This study aimed to evaluate the relationship between sacroiliitis observed in familial Mediterranean fever and hematological inflammatory markers. METHODS: In this study, 168 familial Mediterranean fever patients were examined. A total of 61 familial Mediterranean fever patients who had sacroiliac magnetic resonance imaging due to waist and hip pain were included in the study. According to the magnetic resonance imaging findings, patients were divided into two groups: with and without sacroiliitis. The relationship between hematological inflammatory markers and sacroiliitis was investigated. RESULTS: The frequency of sacroiliitis was found to be 13.6% in all familial Mediterranean fever patients and 37.8% in patients with low back pain who underwent sacroiliac magnetic resonance imaging. Neutrophil count, neutrophil/lymphocyte ratio, monocyte/lymphocyte ratio, and systemic immune-inflammatory index were significantly higher in the sacroiliitis group than in the other group, and this difference was found to be statistically significant (p<0.05). As a result of the receiver operating characteristic analysis, it was observed that neutrophil/lymphocyte ratio, monocyte/lymphocyte ratio, and systemic immune-inflammatory index were very sensitive parameters in determining sacroiliitis in patients with familial Mediterranean fever. CONCLUSION: It was observed that the frequency of sacroiliitis was increased in familial Mediterranean fever patients. It is predicted that hematological inflammatory markers such as neutrophil/lymphocyte ratio, monocyte/lymphocyte ratio, and systemic immune-inflammatory index can be used in the diagnosis of sacroiliitis.

Autoinflammatory diseases: a Latin American multicenter study according to age and sex / Doenças autoinflamatórias: um estudo multicêntrico latino-americano de acordo com o sexo e a idade

ABSTRACT Objective: To evaluate autoinflammatory diseases (AID) according to age at diagnosis and sex, and response to therapy in a large population. Methods: This is a cross-sectional observational study of a Latin American registry using a designed web system for data storage, collected between 2015 and 2018. Any altered findings during follow-up were recorded. The forms were translated into Portuguese and Spanish, including demographic, clinical, laboratory, genetic and treatment characteristics. Results: We included 152 patients, 51.3% male and 75% Caucasian. The median age at disease onset was 2.1 years (0-15.6 years) and median age at diagnosis 6.9 years (0-21.9 years); 111 (73%) were children (0-9 years old), and 41 (27%) were adolescents and young adults (AYA) (10-21 years old). Periodic fever, aphthous stomatitis, pharyngitis, and adenitis syndrome (PFAPA) occurred in 46/152 (30%), chronic non-bacterial osteomyelitis (CNO) in 32/152 (21%), and familial Mediterranean fever (FMF) in 24/152 (15.7%). PFAPA was significantly higher in young children than in AYA (38.7% vs. 7.3%, p<0.001), while CNO were lower (13.5% vs. 41.5%, p<0.001). The frequency of females was significantly higher in CNO (28.4% vs. 14.1%, p=0.031) and lower in FMF (8.1% vs. 23.1%, p=0.011). The most used drugs were glucocorticoids, non-steroidal anti-inflammatory drugs (NSAID), and colchicine. Glucocorticoids and colchicine treatment were used in all AID with good to moderate response. However, cryopyrin-associated periodic syndromes (CAPS) seemed unresponsive to glucocorticoids. NSAIDs and methotrexate were the main medications used to treat CNO. Conclusions: Differences among AID patients were observed in the LA population regarding sex and age at disease diagnosis.

RESUMO Objetivo: Avaliar as doenças autoinflamatórias (DAI) de acordo com sexo e idade no momento do diagnóstico e a resposta terapêutica em uma grande população. Métodos: Este é um estudo observacional transversal de um registro latino-americano que usou um sistema de dados coletados entre 2015 e 2018. Quaisquer achados alterados ao longo do acompanhamento foram registrados. Os formulários foram traduzidos para os idiomas português e espanhol, incluindo características demográficas, clínicas, laboratoriais, genéticas e de tratamento. Resultados: Incluímos 152 pacientes, sendo 51,3% do sexo masculino e 75% da raça branca. A média de idade de início da doença foi de 2,1 anos (0-15,6 anos) e a média de idade de diagnóstico 6,9 anos (0-21,9 anos); 111 (73%) eram crianças (0-9 anos) e 41 (27%) adolescentes/adultos jovens (10-21 anos). A síndrome de febre periódica, estomatite aftosa, faringite e adenite (PFAPA) ocorreu em 46/152 (30%), osteomielite não bacteriana crônica (CNO) em 32/152 (21%) e febre familiar do Mediterrâneo (FMF) em 24/152 (15,7%). A PFAPA foi significativamente maior em crianças pequenas (38,7 vs. 7,3%, p<0,001), e a CNO, em adolescentes/adultos jovens (13,5 vs. 41,5%, p<0,001). A frequência do sexo feminino foi significativamente maior na CNO (28,4 vs. 14,1%, p=0,031) e menor na FMF (8,1 vs. 23,1%, p=0,011). Os medicamentos mais utilizados foram glicocorticoides, anti-inflamatórios não esteroidais (AINE) e colchicina. O tratamento com glicocorticoides e colchicina foi usado em todas as DAI com resposta boa a moderada. No entanto, as síndromes periódicas associadas à criopirina (CAPS) pareciam não responder aos glicocorticoides. AINE e metotrexato foram os principais medicamentos utilizados no tratamento da CNO. Conclusões: Diferenças de pacientes com DAI foram observadas na população latino-americana em pacientes agrupados por sexo e idade ao diagnóstico da doença.

Renal tubular acidosis in hereditary transthyretin amyloidosis (ATTRv) / Acidose tubular renal na amiloidose hereditária por transtirretina (ATTRv)

Abstract Introduction: Hereditary transthyretin amyloidosis (ATTRv) is a severe autosomal dominant systemic disease. It affects the peripheral and autonomic nervous systems, heart, kidneys, and eyes. Amyloid deposition has been demonstrated in the glomerular and tubulointerstitial compartments of the kidney. Therefore, urinary acidification disorders such as renal tubular acidosis (RTA) may be early manifestations of renal involvement in this population. Objective: To evaluate the prevalence of RTA in individuals with ATTRv. Methods: We included symptomatic and asymptomatic individuals with TTR mutation, older than 18 years, GFR >45 mL/min/1.73m2, without systemic metabolic acidosis. Urinary acidification protocol was performed with furosemide and fludrocortisone after 12 h of water deprivation (water deprivation test - WDT) and measurements of urine ammonium ( UNH 4 +) and titratable acidity (UTA). Proximal RTA (pRTA) was diagnosed when FEHCO3>10%. Incomplete form distal RTA (dRTA) was diagnosed if UpH>5.3. Results: We selected 49 individuals with a mean age of 40 (35.5-56.5) years, 63% of which were female, 84% were Caucasian, and mean GFR was 85.5 ± 20.5 mL/min/1.73m2. 94% had the genetic variant Val50Met and 57% were symptomatic. The prevalence of pRTA was 2% and of dRTA was 16.3%. In the subgroup with dRTA, there was no significant increase in excretion of UNH 4 + and UTA. We observed a good correlation between UpH by potentiometry and UpH dipstick. A UpH<5.5 on the dipstick had 100% sensitivity and negative predictive value to exclude dRTA. Conclusion: A high prevalence of RTA was found in individuals with TTR mutations. The UpH dipstick after WDT had good accuracy for screening for dRTA. Further studies are needed to evaluate the impact of early diagnosis and treatment of RTA in this population.

Resumo Introdução: A amiloidose hereditária por transtirretina (ATTRv) é uma doença sistêmica autossômica dominante grave. Afeta os sistemas nervoso periférico e autônomo, coração, rins e olhos. A deposição de amiloide foi demonstrada nos compartimentos glomerular e tubulointersticial do rim. Portanto, distúrbios de acidificação urinária, como acidose tubular renal (ATR), podem ser manifestações precoces de envolvimento renal nessa população. Objetivo: Avaliar a prevalência de ATR em indivíduos com ATTRv. Métodos: Incluímos indivíduos sintomáticos e assintomáticos com mutação na TTR, maiores de 18 anos, TFG >45 mL/min/1,73m2, sem acidose metabólica sistêmica. Realizou-se protocolo de acidificação urinária com furosemida e fludrocortisona após 12 horas de privação hídrica (teste de restrição hídrica - TRH) e medições de amônia urinária ( uNH 4 +) e acidez titulável (uTA) na urina. ATR proximal (ATRp) foi diagnosticada quando FEHCO3>10%. ATR distal (ATRd) de forma incompleta foi diagnosticada se pHu>5,3. Resultados: Selecionamos 49 indivíduos com idade média de 40 (35,5-56,5) anos, 63% mulheres, 84% caucasianos e TFG média de 85,5 ± 20,5 mL/min/1,73m2. 94% apresentaram a variante genética Val50Met; 57% eram sintomáticos. A prevalência de ATRp foi 2% e a de ATRd foi 16,3%. No subgrupo com ATRd, não houve aumento significativo na excreção de uNH 4 + e uTA. Observamos uma boa correlação entre pHU por potenciometria e pHU por fita reagente. Um pHU<5,5 na fita reagente apresentou 100% de sensibilidade e valor preditivo negativo para excluir a ATRd. ConclusÃO: Uma alta prevalência de ATR foi encontrada em indivíduos com mutações na TTR. O pHU por fita reagente após TRH teve boa precisão para triagem de ATRd. São necessários mais estudos para avaliar o impacto do diagnóstico e tratamento precoces da ATR nessa população.

A desqualificação das histórias (in)familiares: análise discursiva na suspensão e destituição do poder familiar / The disqualification of (unfamilar)family histories: discursive analysis in the suspension and destitution of family power / La descalificación de los relatos (intra)familiares: análisis discursivo en la suspensión y remoción del poder familiar / La disqualification des histoires (non)familières: analyse discursive dans la suspension et la suppression du pouvoir familial

Resumo Este estudo analisou o percurso de quatro famílias, destituídas do poder familiar, pelo Sistema de Garantia de Direitos da Criança e do Adolescente no Brasil. A análise do discurso de orientação psicanalítica foi empregada no corpus de informações de cada caso, compreendido por documentos relativos ao acompanhamento dos casos e entrevistas, realizadas com familiares e agentes institucionais. Os resultados apontam para formações discursivas que naturalizam ações judiciais punitivas de suspensão ou destituição do poder familiar, aplicadas hegemonicamente às famílias pobres, nas quais as mulheres são as principais culpabilizadas pelas falhas na gestão de cuidados. Verifica-se, também, a descontinuidade do acompanhamento, retomado quando há repetição da aplicação dessas medidas protetivas, assumindo a característica sintomática de falha. A escuta dos atores desses processos surge como uma estratégia de retificação subjetiva, ultrapassando práticas prescritivas e normativas, ratificadoras da exclusão e de criminalização da pobreza, particularmente das famílias negras.

Abstract This study analyzes the journey of four families, deprived of family power, by the Child and Adolescent Rights Guarantee System in Brazil. The psychoanalytically discourse analysis was used in the corpus of information of each case, comprised of documents relating to the accompaniment of the cases and interviews, carried out with family members and institutional agents. The results point to discursive formations that naturalizes punitive judicial actions of suspension or destitution of family power, hegemonically applied to poor families, in which women are considered as the main culprits for failures in care management. There is also discontinuity in follow-ups, resumed when the application of these protective measures is repeated, assuming the symptomatic characteristic of failure. Listening to the actors in these processes emerges as a subjective rectification strategy, going beyond prescriptive and normative practices, which ratify exclusion and the criminalization of poverty, particularly of black families.

Resumen Este estudio analizó la historia de cuatro familias, privadas de poder familiar por el Sistema de Garantía de los Derechos del Niño y del Adolescente de Brasil. El análisis del discurso de orientación psicoanalítica se utilizó en el corpus de datos de cada caso, compuesto por documentos relativos al seguimiento de los casos, y entrevistas, realizadas con familiares y agentes institucionales. Los resultados apuntan a formaciones discursivas que naturalizan acciones judiciales punitivas de suspensión o remoción del poder familiar, aplicadas hegemónicamente a familias pobres, en las que las mujeres son las principales culpabilizadas de los fallos en la gestión del cuidado. También existe discontinuidad en el seguimiento, que se reanuda cuando se repite la aplicación de estas medidas protectoras, asumiendo la característica sintomática de fallo. La escucha de los actores de estos procesos es una estrategia de rectificación subjetiva, superando las prácticas prescriptivas y normativas que ratifican la exclusión y criminalizan la pobreza, en especial de las familias negras.

Résumé Cette étude a analysé le parcours de quatre familles, privées de pouvoir familial, par le Système de Garantie des Droits de l'Enfant et de l'Adolescent au Brésil. L'analyse du discours d'orientation psychanalytique a été utilisée dans le corpus d'informations de chaque cas, composé de documents relatifs au suivi des cas et d'entretiens, réalisés avec des membres de la famille et des agents institutionnels. Les résultats indiquent des formations discursives qui naturalisent les actions judiciaires punitives de suspension ou de suppression du pouvoir familial, appliquées de manière hégémonique aux familles pauvres, dans lesquelles les femmes sont considérées les principales responsables des échecs de la gestion des soins. Il existe également une discontinuité dans le suivi, repris lors de la répétition de l'application de ces mesures de protection, assumant le caractère symptomatique de l'échec. L'écoute des acteurs de ces processus apparaît comme une stratégie de rectification subjective, dépassant les pratiques prescriptives et normatives, qui entérinent l'exclusion et la criminalisation de la pauvreté, notamment des familles noires.

Screening program for familial hyperchylomicronemia syndrome detection: Experience of a university health system

ABSTRACT Objective: Familial chylomicronemia syndrome (FCS) is a rare autosomal recessive metabolic disorder caused by mutations related to chylomicron metabolism. The objective of this study is to show the development and results of a screening program for FCS in Argentina. Materials and methods: A cross-sectional study was performed. All patients > 18 years with a triglyceride level ≥ 1,000 mg/dL in the period from January 1, 2017 to December 31, 2021 were included. The program was developed in three stages: (1) Review of electronic records and identification of suspected laboratory cases (triglyceride level ≥ 1,000 mg/dL); (2) Identification of suspected clinical cases (all suspected laboratory cases that had no relevant secondary factors) and application of the FCS score to define probable cases (score ≥ 10); (3) Perform genetic tests in probable cases. Results: Globally, 348 suspected laboratory cases (mean age of 49.9 years, 77.3% men) were included. The median triglycerides level was 1,309 mg/dL (interquartile range 1,175-1,607 mg/dL). In total, 231 patients were categorized as suspected clinical cases. After applying the FCS score, 3% of them were classified as "very likely FCS" (probable cases). Four variants of uncertain significance have been identified. No previously reported pathogenic variants were detected. Conclusion: This study shows a screening program for the detection of FCS. Although no patient was diagnosed with FCS, we believe that more programs of these characteristics should be developed in our region, given the importance of early detection of this metabolic disorder.

Brazilian consensus for diagnosis, management and treatment of hereditary transthyretin amyloidosis with peripheral neuropathy: second edition / Consenso brasileiro para o diagnóstico, manejo e tratamento da polineuropatia amiloidótica familiar associada à transtirretina: segunda edição

Abstract Hereditary transthyretin amyloidosis with peripheral neuropathy (ATTRv-PN) is an autosomal dominant inherited sensorimotor and autonomic polyneuropathy with over 130 pathogenic variants identified in the TTR gene. Hereditary transthyretin amyloidosis with peripheral neuropathy is a disabling, progressive and life-threatening genetic condition that leads to death in ~ 10 years if untreated. The prospects for ATTRv-PN have changed in the last decades, as it has become a treatable neuropathy. In addition to liver transplantation, initiated in 1990, there are now at least 3 drugs approved in many countries, including Brazil, and many more are being developed. The first Brazilian consensus on ATTRv-PN was held in the city of Fortaleza, Brazil, in June 2017. Given the new advances in the area over the last 5 years, the Peripheral Neuropathy Scientific Department of the Brazilian Academy of Neurology organized a second edition of the consensus. Each panelist was responsible for reviewing the literature and updating a section of the previous paper. Thereafter, the 18 panelists got together virtually after careful review of the draft, discussed each section of the text, and reached a consensus for the final version of the manuscript.

Resumo Polineuropatia amiloidótica familiar associada a transtirretina (ATTRv-PN) é uma polineuropatia sensitivo-motora e autonômica hereditária autossômica dominante com mais de 130 variantes patogênicas já identificadas no gene TTR. A ATTRv-PN é uma condição genética debilitante, progressiva e que ameaça a vida, levando à morte em ~ 10 anos se não for tratada. Nas últimas décadas, a ATTRv-PN se tornou uma neuropatia tratável. Além do transplante de fígado, iniciado em 1990, temos agora 3 medicamentos modificadores de doença aprovados em muitos países, incluindo o Brasil, e muitas outras medicações estão em desenvolvimento. O primeiro consenso brasileiro em ATTRv-PN foi realizado em Fortaleza em junho de 2017. Devido aos novos avanços nesta área nos últimos 5 anos, o Departamento Científico de Neuropatias Periféricas da Academia Brasileira de Neurologia organizou uma segunda edição do consenso. Cada panelista ficou responsável por rever a literatura e atualizar uma parte do manuscrito. Finalmente, os 18 panelistas se reuniram virtualmente após revisão da primeira versão, discutiram cada parte do artigo e chegaram a um consenso sobre a versão final do manuscrito.

Very low HDL levels: clinical assessment and management

ABSTRACT In individuals with very low high-density lipoprotein (HDL-C) cholesterol, such as Tangier disease, LCAT deficiency, and familial hypoalphalipoproteinemia, there is an increased risk of premature atherosclerosis. However, analyzes based on comparisons of populations with small variations in HDL-C mediated by polygenic alterations do not confirm these findings, suggesting that there is an indirect association or heterogeneity in the pathophysiological mechanisms related to the reduction of HDL-C. Trials that evaluated some of the HDL functions demonstrate a more robust degree of association between the HDL system and atherosclerotic risk, but as they were not designed to modify lipoprotein functionality, there is insufficient data to establish a causal relationship. We currently have randomized clinical trials of therapies that increase HDL-C concentration by various mechanisms, and this HDL-C elevation has not independently demonstrated a reduction in the risk of cardiovascular events. Therefore, this evidence shows that (a) measuring HDL-C as a way of estimating HDL-related atheroprotective system function is insufficient and (b) we still do not know how to increase cardiovascular protection with therapies aimed at modifying HDL metabolism. This leads us to a greater effort to understand the mechanisms of molecular action and cellular interaction of HDL, completely abandoning the traditional view focused on the plasma concentration of HDL-C. In this review, we will detail this new understanding and the new horizon for using the HDL system to mitigate residual atherosclerotic risk.

Intra-abdominal desmoid tumors in familial adenomatous polyposis: How much do clinical and surgical variables interfere with their development?

Abstract Objective: Familial Adenomatous Polyposis is a complex hereditary disease that exposes the carrier to a great risk of Colorectal Cancer (CRC). After prophylactic surgery, intra-abdominal desmoid tumors are known to be one the most important cause of death. Therefore, recognition of increased-risk patients and modification of operative strategy may be crucial. Aim: The objective of this study was to estimate the desmoid tumor risk in relation to various surgical and clinical variables. Methods: Patients who had undergone polyposis since 1958 were included in the study. After exclusion criteria were met, those who had developed desmoid tumors were selected to undergo further evaluation. Results: The study revealed that the risk of developing desmoid tumors was associated with various factors such as sex ratio, colectomy, and reoperations. On the other hand, the type of surgery, family history, and surgical approach did not affect the risk of developing desmoid tumors. The data collected from 146 polyposis patients revealed that 16% had desmoid polyps. The sex ratio was 7:1, and the median age at colectomy was 28.6 years. Family history, multiple abdominal operations, and reoperations were some of the characteristics that were common in desmoid patients. Conclusion: Recognition of clinical (female sex) and surgical (timing of surgery and previous reoperations) data as unfavorable variables associated with greater risk may be useful during the decision-making process.

Familial chylomicronemia syndrome: A comprehensive clinical and genetic approach

Abstract The familial chylomicronemia syndrome (FCS) is characterized by very high levels of circulating triglycerides. FCS is caused by lipoprotein lipase (LPL) deficiency resulting from homozygous or biallelic loss-of-function variants in the LPL or other related genes. Here, we report a case of severe hypertriglyceridemia refractory to conventional therapy in a male patient diagnosed at 33 years of age. LPL activity was below 20%. During the clinical course, the patient developed severe acute pancreatitis in addition to other complications. Two heterozygous variants (c.984G>A and c.1139+6T>C) which had not been previously reported in the major databases were identified in the LPL gene. Treatment with volanesorsen was proposed based on its approved indication as an adjunct to diet in adult patients with confirmed FCS and at high risk for pancreatitis. Volanesorsen was effective and well-tolerated, and the patient did not experience abdominal pain or any other manifestations. The assessment of genetic characterization is essential to guide treatment decisions during follow-up, in addition to the patient's history, their comorbidities and clinical stigmas.

Acometimento do Ventrículo Direito na Cardiomiopatia por Depósito de Glicogênio (PRKAG2): Análise Ecocardiográfica Convencional e Avançada / Right Ventricle Involvement by Glycogen Storage Cardiomyopathy (PRKAG2): Standard and Advanced Echocardiography Analyses

Resumo Fundamento A síndrome do PRKAG2 é uma doença hereditária autossômica dominante rara, de início precoce. Objetivamos descrever os achados ecocardiográficos do ventrículo direito (VD) usando modalidades bi e tridimensionais (2D e 3D), incluindo índices de deformação miocárdica nesta cardiomiopatia. Também objetivamos demonstrar se esta técnica poderia identificar alterações na função do VD que pudessem distinguir quaisquer achados particulares. Métodos Trinta pacientes com síndrome do PRKAG2 (R302Q e H401Q) geneticamente comprovada, 16 (53,3%) do sexo masculino, com idade média de 39,1 ± 15,4 anos, foram submetidos a exame ecocardiográfico completo. A visão de 4 câmaras com foco no VD foi adquirida para medições 2D e 3D. Os testes t de Student ou Wilcoxon-Mann-Whitney foram usados para comparar as variáveis numéricas entre 2 grupos, e p < 0,05 foi considerado significativo. Resultados Doze pacientes (40%) tiveram marca-passo implantado por 12,4 ± 9,9 anos. A espessura diastólica média da parede livre do VD foi de 7,9 ± 2,9 mm. O strain longitudinal de 4 câmaras do VD (SL4VD), incluindo a parede livre e o septo interventricular, foi de -17,3% ± 6,7%, e o strain longitudinal da parede livre do VD (SLPLVD) foi de −19,1% ± 8,5%. A razão apical do SLPLVD mediu 0,63 ± 0,15. A fração de ejeção (FE) 3D média do VD foi de 42,6% ± 10,9% e abaixo dos limites normais em 56,7% dos pacientes. Correlação positiva ocorreu entre FE 3D do VD, SL4VD e SLPLVD, principalmente para pacientes sem marca-passo (p = 0,006). Conclusão O envolvimento do VD em PRKAG2 é frequente e ocorre em diferentes graus. A ecocardiografia é uma ferramenta valiosa na detecção de anormalidades miocárdicas do VD nesta condição. O uso de SL4VD 2D, SLPLVD e FE 3D oferecem indicadores confiáveis de disfunção sistólica do VD nesta cardiomiopatia rara e desafiadora.

Abstract Background PRKAG2 syndrome is a rare, early-onset autosomal dominant inherited disease. We aimed to describe the right ventricle (RV) echocardiographic findings using two and three-dimensional (2D and 3D) modalities including myocardial deformation indices in this cardiomyopathy. We also aimed to demonstrate whether this technique could identify changes in RV function that could distinguish any particular findings. Methods Thirty patients with genetically proven PRKAG2 (R302Q and H401Q), 16 (53.3%) males, mean age 39.1 ± 15.4 years, underwent complete echocardiography examination. RV-focused, 4-chamber view was acquired for 2D and 3D measurements. Student's t or Wilcoxon-Mann-Whitney tests were used to compare numerical variables between 2 groups, and p < 0.05 was considered significant. Results Twelve patients (40%) had a pacemaker implanted for 12.4 ± 9.9 years. RV free wall mean diastolic thickness was 7.9 ± 2.9 mm. RV 4-chamber longitudinal strain (RV4LS), including the free wall and interventricular septum, was -17.3% ± 6.7%, and RV free wall longitudinal strain (RVFWLS) was −19.1% ± 8.5%. The RVFWLS apical ratio measured 0.63 ± 0.15. Mean RV 3D ejection fraction (EF) was 42.6% ± 10.9% and below normal limits in 56.7% of patients. Positive correlation occurred between RV 3DEF, RV4LS, and RVFWLS, especially for patients without a pacemaker (p = 0.006). Conclusion RV involvement in PRKAG2 syndrome is frequent, occurring in different degrees. Echocardiography is a valuable tool in detecting RV myocardial abnormalities in this condition. The use of 2D RV4LS, RVFWLS, and 3DEF offers reliable indicators of RV systolic dysfunction in this rare, challenging cardiomyopathy.

Ophthalmological manifestations of hereditary transthyretin amyloidosis / Manifestações oftalmológicas da amiloidose hereditária por transtirretina

ABSTRACT Transthyretin familial amyloidosis is the most common form of inherited systemic amyloidosis worldwide. The condition develops secondary to more than 100 different point mutations in the transthyretin gene (18q12.1). The mutations lead to abnormal amyloid deposits, mainly in the heart and peripheral nerves. Leptomeningeal and mainly ocular involvement is common. Although there are several different types of treatment available, ocular involvement, which occurs also in liver transplant recipients, remains a major challenge, progressing even in liver transplant recipients. Patients with ocular involvement require efficient ophthalmological follow-up to prevent vision loss. In this review, different forms of ocular involvement characterizing the subtypes of transthyretin mutations were described, and the effects of different treatments were summarized. Further research is necessary to fully elucidate these issues.

RESUMO A amiloidose familiar por transtirretina é a forma mais comum de amiloidose sistêmica hereditária mundialmente. A condição é secundária a mais de 100 mutações ponto diferentes no gene da transtirretina (18q12.1). Mutações levam a depósitos anormais de amilóide principalmente no coração e nos nervos periféricos. O envolvimento leptomeníngeo, e principalmente ocular também é comum. Apesar do advento de várias formas diferentes de tratamento, o envolvimento ocular ainda é um grande problema, progredindo mesmo em pacientes submetidos à transplante hepático. Nesta revisão, avaliamos as diferentes formas de envolvimento ocular presentes entre os subtipos de mutações da transtirretina e os efeitos dos diferentes tratamentos disponíveis. O envolvimento ocular é desafiador na amiloidose familiar por transtirretina, exigindo acompanhamento oftalmológico eficiente para mitigar a perda de visão. Mais pesquisas são necessárias para auxiliar na resolução dessas questões.

Retinal microvascular changes in patients with familial mediterranean fever: a study based on optical coherence tomography angiography / Alterações microvasculares da retina em pacientes com febre mediterrânea familiar: estudo baseado em angiotomografia de coerência óptica

ABSTRACT Purpose: In this study, we aimed to show whether a difference exists between retinal and choroidal microcirculation findings between patients with familial Mediterranean fever and healthy controls. Methods: Thirty-two patients with familial Mediterranean fever and 30 healthy controls were included in the study. All the patients underwent a complete ophthalmologic examination, including best-corrected visual acuity and intraocular pressure measurement. The AngioVue optical coherence tomography angiography device (Optovue, Fremont, CA) with split-spectrum amplitude-decorrelation angiography was used to evaluate and examine the retinal microvascular structure. Three-dimensional en face Optical coherence tomography angiography images were obtained by examining the macula using the 3 x 3 mm scanning protocol in the Angio Retina mode and the optic nerve using the 3 x 3 mm scanning protocol in the Angio Disk mode. All the patients' right eyes were examined. Results: A total of 62 subjects were included in the study, of whom 32 (53.3%) were female and 30 (46.7%) were male. No statistically significant difference was found between the two groups in terms of optic nerve head or radial peripapillary capillary vessel density. On examination, the superficial capillary plexuses were statistically similar between the two groups, but the deep capillary plexus vessel density in the parafovea, superior hemi, temporal, and superior areas were significantly lower in the patients with familial Mediterranean fever. Conclusions: We found that the capillary plexus vessel density was significantly lower in the parafovea, superior hemi, temporal, and superior regions in the patients with familial Mediterranean fever than in the control group. Therefore, OCTA, a noninvasive study, may be useful for understanding the systemic effects of familial Mediterranean fever.

RESUMO Objetivos: Este estudo teve como objetivo mostrar se há diferença entre os achados da microcirculação retiniana e coroidal entre pacientes com febre mediterrânica familiar e um grupo controle saudável. Métodos: Trinta e dois pacientes com febre mediterrânica familiar e 30 controles saudáveis foram incluídos neste estudo. Todos os pacientes foram submetidos a um exame oftalmológico completo, incluindo a acuidade visual melhor corrigida e medida da pressão intraocular. O aparelho AngioVue Optical coherence tomography angiography (Optovue, Fremont, CA) com angiografia de correlação de amplitude de espectro dividido foi utilizado para avaliar e examinar a estrutura microvascular da retina. As angiotomografias de coerência ópticas en face tridimensionais foram obtidas examinando o protocolo de varredura macular 3 x 3 mm (modo angio retina) e o nervo óptico com o protocolo de varredura 3 x 3 mm (modo angio-disco). Todos os olhos direitos dos pacientes foram examinados. Resultados: Foram incluídos neste estudo, 62 sujeitos, dos quais 32 (53,3%) eram do sexo feminino e 30 (46,7%) do sexo masculino. Não houve diferença estatisticamente significativa entre os dois grupos quanto à densidade dos vasos da cabeça do nervo óptico ou da densidade dos vasos capilares peripapilares radiais. Durante o exame, os plexos capilares superficiais foram estatisticamente semelhantes entre esses dois grupos, mas a densidade profunda dos vasos do plexo capilar nas areas parafovea, hemi superior, temporal e superior foram significativamente menores nos pacientes com febre mediterrânica familiar. Conclusões: Verificamos que a densidade dos vasos do plexo capilar foi significativamente menor nas regiões parafovea, hemi superior, temporal e superior em pacientes com febre mediterrânica familiar em comparação com o grupo controle. Portanto, pode ser útil usar a angiotomografia de coerência óptica, por tratar-se de um estudo não invasivo, para melhor compreensão dos efeitos sistêmicos da febre mediterrânica familiar.
