Introducción: Emicizumab es el primer tratamiento no sustitutivo para profilaxis en hemofilia A grave. Objetivos: Describir los resultados de nuestros pacientes en profilaxis con emicizumab, según la práctica clínica habitual. Material y métodos: Seguimiento de 13 pacientes desde el inicio de la profilaxis, registro de hemorragias, cirugías, reacciones adversas y necesidad o no de tratamiento factorial. Se midieron los niveles plasmáticos en las visitas de seguimiento; la técnica ha sido coagulativa en una etapa, modificada mediante dilución 1:20. Resultados: La mediana de niveles plasmáticos fue de 52,2mg [30,7-71,9]. La profilaxis resultó segura y eficaz; solamente se contabilizó una hemorragia espontánea a lo largo del tiempo y no precisó tratamiento. No hubo episodios tromboembólicos ni reacciones graves de hipersensibilidad, anafilaxia o anafilactoides. La incidencia de reacciones en el lugar de la inyección fue del 8%. El abordaje perioperatorio en las intervenciones menores se llevó a cabo sin tratamiento factorial coadyuvante, en 2 cirugías mayores se precisó una dosis de concentrado de FVIII plasmático en el paciente con hemofilia A sin inhibidor y FVII en el paciente con inhibidor, y fue suficiente para parar la hemorragia. Conclusión: Este estudio demostró que la farmacocinética de emicizumab y su vida media aseguran niveles óptimos con tratamiento profiláctico a las dosis establecidas en la ficha técnica.(AU)

Influência do tratamento fisioterapêutico na independência funcional de pessoas com hemofilia submetidas à sinovectomia radioativa / Influence of physiotherapeutic treatment on the functional independence of people with hemophilia submitted to radioactive sinovectomy

A sinovectomia radioativa (SR) é considerada o tratamento de eleição no controle da sinovite crônica não responsiva ao tratamento conservador, sendo recomendado tratamento fisioterapêutico para a melhora da funcionalidade. Objetivo: Verificar a influência do tratamento fisioterapêutico na independência funcional e saúde articular de hemofílicos após tratamento com SR. Método: Trata-se de um estudo descritivo, retrospectivo, analítico e metodologia quali-quantitativa. Realizou-se avaliação fisioterapêutica, aplicação do HJHS para avaliação da saúde articular e Escore FISH para avaliação da independência funcional. Os participantes foram subdivididos em dois grupos de acordo com a realização ou não da fisioterapia após a SR. Resultados: Participaram do estudo 8 pessoas com hemofilia A, sexo masculino, média de idade de 19±5,3 anos. Foram 12 articulações submetidas a SR, dessas 41,67% cotovelos, 33,33% joelhos e 25% tornozelos. Na comparação dos grupos, não houve diferença estatística entre os eles nas variáveis: saúde articular e a Independência Funcional. Conclusão: O estudo é uma primeira tentativa de descrever o impacto da fisioterapia na independência funcional e saúde articular de hemofílicos submetidos à SR. Embora possua limitações, foi possível observar que o grupo que não realizou fisioterapia apresentava melhor saúde articular e melhor independência funcional previamente à SR em comparação ao grupo que realizou fisioterapia; porém, o grupo fisioterapia apresentava pior quadro global, com a funcionalidade impactada por outras articulações e não somente aquela tratada com SR, apresentando maior número de articulações alvo.

Radioactive synovectomy (RS) is considered the treatment of choice in the control of chronic synovitis resistant to conservative treatment, and physiotherapy is recommended to improve functionality after procedure. Objective: The aim was to verify the effects of physiotherapy on functional independence and joint health after RS. Method: This is a descriptive, retrospective, analytical study with qualitative/quantitative methodology. Physiotherapeutic evaluation, Hemophilia Joint Health Score (HJHS) application for joint outcome assessment and Functional Independence Score in Hemophilia (FISH) were used to measure the patient's functional ability. The participants were divided into two groups: one group underwent a physiotherapy program and one not treated with physiotherapy after RS. Results: The study included 8 people with hemophilia A, all male, their mean age was 19±5.3 years. Twelve joints were submitted to RS, in which 41.67% elbows, 33.33% knees and 25% ankles. In the comparison of the groups, there was no statistically significant difference between them in joint health and functional independence. Conclusion: The study is a first attempt to describe the impact of physiotherapy on functional independence and joint health of hemophilic patients submitted to SR. Although this study has limitations, it was possible to observe that the group not treated with physiotherapy had better joint health and better functional independence prior to SR compared to the group that underwent physiotherapy, but the group treated with physiotherapy had worse overall health and have their functionality impacted by joints other than those treated with RS, presenting a higher number of target joints.

Hemofilia adquirida tipo A

La hemofilia adquirida es un trastorno hemostático causado por la presencia de autoanticuerpos inhibidores contra el F VIII de la coagulación. Clínicamente se presenta como sangrado espontáneo, principalmente en piel y tejidos blandos, y a diferencia de la hemofilia congénita, la hemartrosis es rara. Se presenta el caso de un paciente de sexo masculino, de 60 años, previamente sano, que acude a consulta por cuadro de 8 días de evolución de aparición de hematomas a nivel de miembro superior e inferior. Durante su evolución presenta TTPA alargado y concentraciones bajas de F VIII.

Acquired hemophilia is a hemostatic disorder caused by the presence of inhibitory autoantibodies against coagulation F VIII. Clinically it presents as spontaneous bleeding, mainly in the skin and soft tissues, and unlike congenital hemophilia, hemarthrosis is rare. We present the case of a 60-year-old male patient, previously healthy, who came to the clinic due to an 8-day history of hematomas on the upper and lower limbs. During its evolution it presents prolonged APTT and low concentrations of F VIII.

Hemofilia A adquirida en el posparto: reporte de caso / Postpartum-acquired hemophilia A: case report

RESUMEN La hemofilia A adquirida es un trastorno hemorrágico poco frecuente a nivel mundial, y se caracteriza por la presencia de autoanticuerpos inhibidores dirigidos hacia un factor de la coagulación, en la mayoría de ocasiones el factor VIII. Las etiologías son variadas, entre las que se encuentra el posparto. Se presenta el caso de una paciente de 34 años con dolor lumbar, hematuria y hematoma en región glútea derecha, sin antecedentes previos de sangrado. Por extensión de las manifestaciones hemorrágicas es transferida al servicio de emergencia. Los exámenes auxiliares de perfil de coagulación, prueba de mezclas y medición de los títulos de inhibidores del factor VIII permitieron confirmar el diagnóstico. El caso resalta la importancia de considerar esta patología en una paciente puérpera con persistencia de sangrado por herida operatoria, hematoma extenso y sin historia de sangrado previo.

ABSTRACT Acquired hemophilia A is a rare bleeding disorder worldwide, characterized by the presence of inhibitory autoantibodies directed against a coagulation factor, most often factor VIII. There are several possible causes, and it can occur during the postpartum period. We present the case of a 34-year-old female patient with back pain, hematuria and a right gluteal hematoma, with no previous history of bleeding. She was transferred to the emergency department due to the extension of the hemorrhagic manifestations. Diagnosis was confirmed with the coagulation profile, mixing test and the assessment of factor VIII inhibitor tier. The case highlights the importance of considering this condition in a postpartum patient with persistent postoperative bleeding, extensive hematoma and no history of previous bleeding.

Escores de Risco Cardiovascular entre Adultos Assintomáticos com Hemofilia / Cardiovascular Risk Scores among Asymptomatic Adults with Haemophilia

Resumo Fundamento A taxa de mortalidade de pessoas com hemofilia (PCH) no Brasil está diminuindo, mas a incidência relativa de mortes associadas a doenças cardiovasculares (DCV) tem aumentado. Objetivos Nosso objetivo foi descrever o escore de risco de DCV de PCHs de acordo com a ferramenta Pooled Cohort Equations Risk (PCER) Calculator e suas recomendações de tratamento. Além disso, foram comparadas as estimativas da PCER com o respectivo escore de risco de Framingham (FRS). Métodos Este estudo transversal incluiu PCHs do sexo masculino, com idade igual ou superior a 40 anos, tratados no Centro de Tratamento Integral de Hemofilia de Pernambuco (Recife/Brasil). PCHs com um evento cardiovascular prévio ou colesterol lipídico de baixa densidade ≥ 5,0 mmol/L foram excluídas. Entrevistas, revisões de prontuários médicos e exames de sangue foram realizados. A ferramenta PCER foi utilizada para estimar o risco de DCV e compará-lo com o respectivo FRS. Um valor de p < 0,05 foi aceito como estatisticamente significativo. Resultados Trinta PCHs foram incluídas. A idade mediana foi de 51,5 [intervalo interquartil-IIQ; 46,0-59,5] anos. A prevalência de obesidade, hipertensão arterial sistêmica, diabetes mellitus, hipertrigliceridemia, hipercolesterolemia e hipoHDLemia foi de 20%, 67%, 24%, 14%, 47% e 23%, respectivamente. O escore mediano da PCER foi de 6,9% [IIQ; 3,1-13,2], com 50% de alto risco (PCER ≥ 7,5%). O uso de estatina foi sugerido para 54% das PCHs. A pressão arterial estava mal controlada em 47% das PCHs. A concordância entre PCER e FRS foi de 80% (κ = 0,60; p = 0,001). Conclusões Metade dos homens com hemofilia, com 40 anos de idade ou mais, teve um alto risco de desenvolver DCV em 10 anos, com fortes recomendações para melhorar o controle da dislipidemia e da pressão arterial.

Abstract Background The mortality rate of Brazilian people with haemophilia (PwH) is decreasing, but the relative incidence of deaths associated with cardiovascular disease (CVD) is increasing. Objectives We aimed to describe the CVD risk score of PwH according to Pooled Cohort Equations Risk (PCER) Calculator tool and its treatment recommendations. We also compared the PCER estimates with the respective Framingham Risk Score (FRS). Methods This cross-sectional study included male PwH ≥ 40 years treated at the Comprehensive Haemophilia Treatment Centre of Pernambuco (Recife/Brazil). PwH with a previous CVD event or a low-density lipid cholesterol ≥ 5.0 mmol/L were excluded. Interviews, medical file reviews, and blood tests were performed. The PCER tool was used to estimate the CVD risk and compare it with the respective FRS. A p-value < 0.05 was accepted as statistically significant. Results Thirty PwH were included. Median age was 51.5 [interquartile range-IQR; 46.0-59.5] years. The prevalence of obesity, systemic arterial hypertension, diabetes mellitus, hypertriglyceridaemia, hypercholesterolaemia, and hypoHDLaemia were 20%, 67%, 24%, 14%, 47%, and 23%, respectively. The median PCER score was 6.9% [IQR; 3.1-13.2], with 50% having a high risk (PCER ≥ 7.5%). Statin use was suggested for 54% of PwH. Blood pressure was poorly controlled in 47% of PwH. The agreement between PCER and FRS was 80% (κ = 0.60; p = 0.001). Conclusions Half of the male people with haemophilia aged 40 years or older had a 10-year high risk of developing CVD with strong recommendations to improve control of dyslipidaemia and blood pressure.

Evaluación de profilaxis con factor VIII de origen plasmático en pacientes con hemofilia A severa / Evaluation of factor VIII prophylaxis of plasmatic origin in patients with severe hemophilia A / Avaliação da profilaxia do fator VIII de origem plasmática em pacientes com hemofilia A grave

Introducción: la hemofilia A severa (HAS) es una enfermedad hemorrágica hereditaria causada por un déficit de factor VIII (FVIII) menor al 1%. Se presenta principalmente con sangrados articulares, los cuales provocan una artropatía hemofílica que afecta su independencia funcional. El uso de la profilaxis terciaria con FVIII ofrece beneficios en adultos disminuyendo la tasa anual de sangrado (TAS) y mejorando la independencia funcional. Objetivo: determinar el porcentaje de pacientes que logran mantener un nivel de FVIII mayor al 1%, conocer si existe una mejora en la independencia funcional, así como una disminución en la TAS con el régimen profiláctico empleado. Métodos: estudio observacional, analítico. Se incluyó a los pacientes con HAS que se controlaron en el Hospital de Clínicas "Dr. Manuel Quintela" durante 2020 en profilaxis con FVIII durante 12 meses. Se obtuvieron tres muestras separadas en el tiempo para dosificación de FVIII y se evaluó la TAS y la independencia funcional en cada paciente. Resultados: se analizaron ocho pacientes, todos presentaron valores de FVIII superiores al 1% a la hora y 24 horas posterior a la administración de FVIII. Los episodios de sangrado se redujeron 4,76 veces con el uso de la profilaxis (p = 0,019). La independencia funcional mostró que 5/8 pacientes mejoraron al menos 1 punto del score. Conclusiones: la profilaxis terciaria en estos pacientes fue beneficioso en reducir la TAS y mejorar su capacidad funcional.

Summary: Introduction: severe hemophilia A (SAH) is an hereditary hemorrhagic disease, caused by a factor VIII (FVIII) deficiency of less than 1%. It presents with joint bleeding mainly, which causes a hemophilic arthropathy, which affects its functional independence. The use of tertiary prophylaxis with FVIII offers benefits in adults by decreasing the annual bleeding rate (ABR) and improving functional independence. Objective: to determine the percentage of patients who manage to maintain an FVIII level greater than 1%, to know if there is an improvement in functional independence, as well as a decrease in the ABR with the prophylactic regimen used. Methods: observational, analytical study. Patients with SAH who were controlled at the Hospital de Clínicas "Dr. Manuel Quintela", during the year 2020, in prophylaxis with FVIII for 12 months were included. Three samples separated in time for FVIII dosing were obtained and the ABR and functional independence were evaluated in each patient. Results: 8 patients were analyzed, all presented FVIII higher than 1% at one hour and 24 hours after the administration of FVIII. The bleeding episodes were reduced 4.76 times with the use of Prophylaxis (p = 0.019). Functional independence showed that 5/8 patients improved at least 1 point in the Score. Conclusions: tertiary prophylaxis in these patients was beneficial in reducing SAD and improving their functional capacity.

Analysis of epidemiological and economic data of hemophilia A patients in Brazil / Análise de dados epidemiológicos e econômicos de pacientes com hemofilia A no Brasil

Objective: To describe the annual medical direct costs per hemophilia A (HA) patient in the Brazilian public healthcare system (SUS) and to understand and describe the patients' hospital journey, demographical characteristics, and the procedures in the. Methods: This retrospective analysis of DataSUS databases. Data from individuals with registries of HA treatment were gathered between January 1st, 2018, and June 30th, 2021. Besides the D66 ICD-10th code (HA), were also considered the occurrence of some procedures like factor VIII dosage and by-pass therapy dispensation or administration as inclusion criteria. Exclusion criteria were occurrence of factor IX dispensation and female patients were excluded, among others. A record linkage using sociodemographic characteristics was conducted to identify unique patients. Results: Were identified 2,298 individuals underwent ambulatory and 1,018 underwent hospital treatments. The results show that most patients are from the Southeast region of the country, white and middle-aged individuals. The median cost of HA treatment per patient-year was BRL 90.36 for ambulatory care and BRL 1,015.31 for hospital care procedures. The costs were significantly higher for more severe patients and for those between 12 and 18 years old (BRL 1,974.75 and BRL 1,049.09, respectively). Conclusion: The evidence demonstrated encourages the implementation of policies aiming to improve the quality of care provided to patients with HA. Providing referral centers for hemophiliac patients is primordial for the success of the treatment and can result in efficiency.

Além do código D66 CID-10 (HA), foi considerada a ocorrência de procedimentos como dosagem do fator VIII e dispensação ou administração de terapia de by-pass como critérios de inclusão. Dentre os critérios de exclusão, destacam-se a dispensação do fator IX e indivíduos do sexo feminino. Um pareamento de registros usando características sociodemográficas foi realizado para identificar pacientes únicos. Resultados: Foram identificados 2.298 indivíduos em tratamento ambulatorial e 1.018 em tratamento hospitalar. Os resultados mostraram que a maioria dos pacientes são da região Sudeste do país, brancos e de meia-idade. O custo médio do tratamento da HA por paciente-ano foi de R$ 90,36 para atendimento ambulatorial e de R$ 1.015,31 para atendimento hospitalar. Os custos foram significativamente maiores para pacientes mais graves e entre 12 e 18 anos (R$ 1.974,75 e R$ 1.049,09, respectivamente). Conclusão: As evidências demonstradas incentivam a implementação de políticas que visem melhorar a qualidade da assistência prestada aos pacientes com HA. A disponibilização de centros de referência para pacientes hemofílicos é primordial para o sucesso do tratamento e pode resultar em maior eficiência.

Self-efficacy for weight control and quality of life in Mexican patients with hemophilia / Autoeficacia para el control de peso y calidad de vida en pacientes mexicanos con hemofilia

Introduction: Perceived self-efficacy is closely related to an adequate quality of life en general well-being of people, but few studies have studied this relationship in people with hemophilia. Objective: To determine the degree of relationship between perceived self-efficacy for weight control and quality of life in people with and without hemophilia, comparing both variables in case-control groups. Methods: The sample made up, for convenience, of 40 participants, with two matched groups. The group of cases consisted of 20 males between 19 and 24 years of age (M = 19.50, SD = 1.47) with hemophilia type A. The control group consisted of 20 males who did not present hemophilia, matched in age and weight status, between the ages of 18 and 24 years of age (M= 19.59, SD= 1.44). Participants answered the "Self-efficacy for Weight Control" questionnaire and the World Health Organization Quality of Life Bref" questionnaire. Descriptive statistics where used to describe the factors of each instrument. Student's t-test was used to compare differences between the two groups. Results: Only the Daily physical activity dimension showed a statistical difference in the control group. According to the Pearson correlation, a positive correlation was found between the Scheduled physical activity, Daily physical activity and Physical health dimensions. Conclusions: It is concluded that physical exercise, weight control, nutritional counseling and psychological support are essential for the quality of life, especially for people with hemophilia, which complements medical treatment.

Introducción: La autoeficacia percibida está estrechamente relacionada con una adecuada calidad de vida y el bienestar en general de las personas, pero pocos estudios han analizado esta relación en personas con hemofilia. Objetivo: Determinar el grado de relación entre la autoeficacia percibida para el control de peso y la calidad de vida en personas con y sin diagnóstico de hemofilia, comparando ambas variables en grupos caso-control. Métodos: La muestra por conveniencia estuvo compuesta por 40 participantes, clasificados en dos grupos. El grupo de casos estuvo constituido por 20 varones entre 19 y 24 años de edad (M= 19,50, DE= 1,47) con diagnóstico de hemofilia tipo A. El grupo control estuvo formado por 20 varones que no presentaban hemofilia, pareados en edad y peso, con edades entre 18 y 24 años (M= 19.59, DT= 1.44). Todos los participantes respondieron el "Cuestionario de Autoeficacia para el Control de Peso" y el "Cuestionario Breve de Calidad de Vida de la Organización Mundial de la Salud". Se obtuvieron análisis descriptivos mediante medias y desviaciones estándar sobre los factores de cada instrumento. Se utilizó la prueba t de Student para la diferencia de medias. Resultados: Se hallaron diferencias entre el grupo de casos y controles solo en la dimensión Actividad física cotidiana a favor del grupo controles. De acuerdo a la correlación de Pearson, se encontró una correlación positiva entre la dimensión Actividad física programada, Actividad física cotidiana y Salud física. Conclusiones: Se constata que el ejercicio físico, el control de peso, la asesoría nutricional y el apoyo psicológico son indispensables para la calidad de vida, en especial de las personas con hemofilia, lo cual complementa el tratamiento médico.

Hemofilia A adquirida: un diagnóstico de infarto / Acquired Hemophilia A: a heart attacking diagnosis

Resumen La hemofilia A adquirida es una entidad poco reportada y potencialmente fatal, que se asocia con la aparición de autoanticuerpos contra el factor VIII de la coagulación. Si bien puede estar subestimada, se calcula una incidencia aproximada de 1 a 1.5 casos por millón de habitantes con una mortalidad reportada entre el 9 y el 33%. Se manifiesta con equimosis extensas espontáneas y sangrado en mucosas, tracto gastrointestinal o en el periodo postparto. Se debe sospechar en adultos a partir de la cuarta década de la vida con sangrados espontáneos y un tiempo parcial de tromboplastina prolongado en ausencia de anticoagulante lúpico. Se reporta el caso de un adulto mayor con cardiopatía isquémica, en quien, en el contexto de un evento coronario agudo, se diagnosticó hemofilia A adquirida ante la presencia de sangrado subcutáneo extenso en cuello, con compresión de faringe y laringe que amenazó su vida representando un verdadero reto terapéutico.

Abstract Acquired hemophilia A is an underreported and potentially fatal entity that is associated with the formation of autoantibodies against coagulation factor VIII. Although it may be underestimated, the estimated incidence is between 1-1.5 cases per million people with a reported mortality between 9 and 33%2. It presents with extensive spontaneous ecchymosis, mucosal, gastrointestinal, or postpartum bleeding. It should be suspected in adults from the fourth decade of life with spontaneous bleeding and prolonged TPT in the absence of lupus anticoagulant. We report the case of an older adult with ischemic heart disease in the context of an acute coronary syndrome, who was diagnosed with acquired hemophilia A and presented with significant cervical subcutaneous bleeding with pharyngeal and laryngeal compression that threatened his life, constituting a real therapeutic challenge.

Autoestima y estilos de afrontamiento: predictores de la calidad de vida en personas con hemofilia / Self-esteem and coping skills: predictors of quality of life in patients with hemophilia

Introducción: La hemofilia es un trastorno hemorrágico que causa dolor y daños articulares graves. Las personas con esta condición de salud suelen presentar problemas psicosociales como baja autoestima y dificultad para enfrentar la enfermedad, lo cual puede impactar negativamente en su calidad de vida relacionada a la salud (CVRS). Objetivo: Analizar el efecto predictor de la autoestima y las estrategias de afrontamiento hacia la CVRS en personas con hemofilia. Métodos: Estudio cuantitativo, no experimental, de tipo correlacional, con muestra por conveniencia, realizado en 60 participantes con hemofilia, edades comprendidas entre 15 y 67 años (media = 27,43, desviación estándar = 11,32). Se utilizaron los cuestionarios: Calidad de Vida Específica para Hemofilia, Autoestima y Afrontamiento al Dolor Crónico. Se realizaron análisis descriptivos, correlación de Pearson y análisis de regresión lineal múltiple con el método por pasos. Resultados: Se obtuvo que el nivel de CVRS fue mayormente moderado; sin embargo, se observaron niveles bajos en las dimensiones Deporte y tiempo libre y Futuro. La dimensión Éxito de la escala de autoestima correlacionó positivamente con las dimensiones Deporte y tiempo libre (r(60)= 0,59), Salud física (r(60)=0,54) y Autopercepción (r(60)=0,48) de la escala calidad de vida; además de haber mostrado un nivel alto de predicción de la calidad de vida (R 2 = 0,35, p= 0,00). Conclusiones: Se comprobó que la autoestima resulta ser una variable predictora de la CVRS de los pacientes con hemofilia. Se requiere fortalecer la autoestima y la manera de enfrentarse ante el dolor crónico en personas con este padecimiento en pro de su calidad de vida y bienestar(AU)

Introduction: Hemophilia is a bleeding disorder that causes severe pain and damage to the joints. People with this health condition often present psychosocial problems such as low self-esteem and difficulty facing their disease, which can negatively impact their health-related quality of life (HRQoL). Objective: To analyze the predictive effect of self-esteem and coping strategies towards HRQL in people with hemophilia. Methods: This was a quantitative, non-experimental, correlational study, with a convenience sample, carried out in 60 participants with hemophilia, ages between 15 and 67 years (mean = 27.43, standard deviation = 11.32). The Specific Quality of Life for Hemophilia, Self-esteem and Coping with Chronic Pain questionnaires were used. Descriptive analyzes. Pearson correlation and multiple linear regression analysis were performed with the stepwise method. Results: It was found that the level of HRQL was mostly moderate, however, low levels were observed in the Sports and free time and Future dimensions. The Success dimension of the self-esteem scale positively correlated with the Sports and free time dimensions (r(60) = 0.59). Physical health (r(60) = 0.54) and Self-perception (r(60) = 0.48) of the quality of life scale, in addition to having shown a high level of prediction of quality of life (R2 = 0.35, p = 0.00). Conclusions: It was found that self-esteem turns out to be a predictor variable of HRQL in patients with hemophilia. It is necessary to strengthen self-esteem and the way of coping with chronic pain in people with this condition in favor of their quality of life and well-being(AU)

Autonomía y dignidad en personas que viven con hemofilia / Autonomy and dignity in people living with hemophilia

INTRODUCCIÓN. La hemofilia es una condición rara hereditaria, crónica, potencialmente discapacitante e incapacitante, caracterizada por frecuentes sangrados debidos al déficit del factor VIII coagulante, Hemofilia A o del factor IX Hemofilia B. Las evaluaciones de calidad de vida en personas con hemofilia, basadas principalmente en el aspecto biológico, llevaron a considerar un importante enfoque bioético que evalúe la afectación de la autonomía y dignidad debida a la enfermedad. OBJETIVO. Registrar la percepción de la autonomía y dignidad de personas que viven con hemofilia. MATERIALES Y MÉTODOS. Estudio descriptivo transversal. Población de 92 y muestra de 28 varones mayores de 18 años con diagnóstico de hemofilia, atendidos en la Clínica de Coagulopatías Congénitas del Hospital de Especialidades Carlos Andrade Marín en el periodo marzo 2021 a agosto del 2021. Se excluyó a varones menores de 18 años atendidos en otras instituciones del Sistema Nacional de Salud. Estudio basado en el desarrollo de las capacidades centrales descritas por Martha Nussbaum. Se aplicó el test The Hemophilia Well Being Index que evaluó calidad de vida con relación al bienestar personal asociado a salud, y la herramienta Body Mapping que analizó en base al interpretativismo fenomenológico. RESULTADOS. El 100% de personas presentaron afectación en algún área de la vida investigada por el Hemophilia Well Being Index, que se confirma con las expresiones escritas y gráficas recopiladas por el Body Mapping. CONCLUSIÓN. La autonomía y dignidad se encuentran afectadas en las personas que viven con hemofilia, al igual que las capacidades centrales; es importante valorar cómo estos parámetros afectan la consecución de logros, lo que se debe considerar en estudios futuros.

INTRODUCTION. Hemophilia is a rare hereditary, chronic, potentially disabling and incapacitating condition, characterized by frequent bleeds due to deficiency of clotting factor VIII, Hemophilia A or factor IX Hemophilia B. Quality of life assessments in people with hemophilia, mainly based on the biological aspect, led to consider an important bioethical approach that evaluates the impairment of autonomy and dignity due to the disease. OBJECTIVE. To record the perception of autonomy and dignity of people living with hemophilia. MATERIALS AND METHODS. Cross-sectional descriptive study. Population of 92 and sample of 28 males over 18 years of age with a diagnosis of hemophilia, attended at the Congenital Coagulopathy Clinic of the Carlos Andrade Marin Specialty Hospital in the period March 2021 to August 2021. Males under 18 years of age attended in other institutions of the National Health System were excluded. The study was based on the development of the central capabilities described by Martha Nussbaum. The test The Hemophilia Well Being Index was applied, which evaluated quality of life in relation to personal wellbeing associated with health, and the tool Body Mapping which analyzed based on phenomenological interpretivism. RESULTS. 100% of people presented affectation in some area of life investigated by the Hemophilia Well Being Index, which is confirmed by the written and graphic expressions collected by the Body Mapping. CONCLUSION. Autonomy and dignity are affected in people living with hemophilia, as are core capacities; it is important to assess how these parameters affect achievement, which should be considered in future studies.

Statements about hemophilia A in Brazil: an expert Delphi panel / Consensos em hemofilia A no Brasil: painel Delphi de especialistas

Objective: Understanding unmet needs related to hemophilia A management in Brazil is critical for supporting decision-making. Methods: A modified Delphi consensus panel was conducted. Hematologists with extensive experience treating hemophilia in the Brazilian Public Health System were invited to answer questions regarding indicators of severe hemophilia prophylaxis effectiveness, emicizumab treatment indications, and bypassing agents used to reduce bleeding in patients with inhibitors, immune tolerance induction (ITI) use, and adherence. The consensus was defined as ≥75% of votes in Round 1 or using a 5-point Likert-type scale (1 = strongly disagree, 2 = disagree, 3 = neither agree nor disagree, 4 = agree, and 5 = strongly agree) in Round 2, which included questions not reaching minimum cut-off in the first step. Results: Nine expert panelists with extensive experience in the Brazilian Public Health System participated. The panel reached an agreement on recommendations about prophylaxis, bleeding treatment patterns, and bleeding sites. From patients' perspectives, venous access and infusion frequency were the most significant barriers to improving patient treatment. According to most experts, emicizumab will not replace ITI or long-term factor VIII therapy. Still, emicizumab was thought to be a good therapeutic option for patients with difficult venous access, patients requiring central venous access, in the presence of inhibitors, or patients experiencing infusion-related pain. Conclusion: The information gleaned from this study may be helpful to both decision-makers and those in charge of developing healthcare economic models for the treatment of hemophilia A in Brazil.

Objetivo: É fundamental entender as necessidades não atendidas relacionadas ao manejo da hemofilia A no Brasil. Métodos: Foi conduzido um painel Delphi modificado. Foram convidados hematologistas com vasta experiência no tratamento de hemofilia no SUS para responder a perguntas sobre indicadores de eficácia da profilaxia, indicações de tratamento com emicizumabe, uso de agentes de bypass, uso de indução de tolerância imunológica (ITI) e adesão. O consenso foi definido como ≥75% dos votos na rodada 1 ou usando uma escala do tipo Likert de 5 pontos (1 = discordo totalmente, 2 = discordo, 3 = não concordo nem discordo, 4 = concordo e 5 = concordo totalmente) na segunda rodada, que incluiu questões que não atingiram o corte mínimo na primeira etapa. Resultados: Nove especialistas participaram e houve consenso sobre recomendações para profilaxia, padrões de tratamento de sangramento e locais de sangramento. O acesso venoso e a frequência da infusão foram identificados como as barreiras mais significativas para melhorar o tratamento do paciente. De acordo com a maioria, emicizumabe não substituirá a ITI ou tratamento com fator VIII de longo prazo. Emicizumabe foi considerado uma boa opção terapêutica para

Equidade em situações-limite: acesso ao tratamento para pessoas com hemofilia / Equity in limit situations: access to treatment for people with hemophilia / Equidad en situaciones límite: acceso al tratamiento para personas con hemofilia

Resumo Hemofilia é uma condição hematológica rara e seu tratamento é alvo de inovação terapêutica. No encontro entre necessidades do paciente, condutas do clínico e orientação do gestor de saúde, surge o conflito: o protocolo é um mínimo ou um máximo terapêutico? As decisões clínicas em debate com a alocação de recursos levam à discussão sobre equidade nessas situações-limite. O método do presente estudo é compreensivo, mediante análise bioética de 14 decisões judiciais acerca do acesso ao tratamento de hemofilia. As decisões de garantia de acesso aos tratamentos pressupõem vinculação ética com o paciente; a clínica conserva uma dimensão de equidade ao permitir que o tratamento seja singular e as doses previstas em protocolo sejam sugestões e não limites. Do ponto de vista ético, estas são expressões de justiça, de precaução e de consideração dos interesses do paciente.

Abstract Hemophilia is a rare hematological condition and its treatment is the target of therapeutic innovation. In the meeting between patient needs, clinician conducts and guidance from the health manager, a conflict arises: is the protocol a therapeutic minimum or maximum? Clinical decisions under discussion with the allocation of resources lead to the discussion about equity in such limit situations. The method of the present study is a comprehensive bioethical analysis of 14 legal decisions about the access to hemophilia treatment. Decisions to guarantee access to treatments presuppose ethical link with the patient; the clinic retains a dimension of equity by allowing the treatment to be unique and the doses provided for in the protocol are suggestions and not limits. From an ethical point of view, these are expressions of justice, precaution and consideration of a patient's interests.

Resumen La hemofilia es un trastorno hematológico raro, cuyo tratamiento es objeto de innovación terapéutica. Ante las necesidades del paciente, la conducta del clínico y la orientación del gestor de salud, surge el conflicto: ¿el protocolo es un mínimo o un máximo terapéutico? Las decisiones clínicas en debate con la asignación de recursos plantean la discusión sobre la equidad en estas situaciones límite. Este estudio se basa en el método comprensivo a través de un análisis bioético de 14 decisiones judiciales sobre el acceso al tratamiento de la hemofilia. Las decisiones para garantizar el acceso a los tratamientos suponen un vínculo ético con el paciente; la clínica mantiene una dimensión de equidad al permitir que el tratamiento sea único y las dosis previstas en el protocolo sean sugerencias y no límites. Desde el punto de vista ético, estas son expresiones de justicia, de precaución y consideración de los intereses del paciente.
