Seguimiento de niños con diagnóstico de asma grave antes y durante la pandemia por COVID-19 / Follow-up of children diagnosed with severe asthma before and during the COVID-19 pandemic

En la pandemia por COVID-19 se exploraron estrategias de atención para garantizar el seguimiento de niños con asma grave. Estudio prospectivo, observacional, comparativo. Se incluyeron pacientes del programa de asma grave de un hospital pediátrico de tercer nivel (n 74). Se evaluó el grado de control, exacerbaciones y hospitalizaciones durante un período presencial (PP), marzo 2019-2020, y uno virtual (PV), abril 2020-2021. En el PP, se incluyeron 74 pacientes vs. 68 (92 %) del PV. En el PP, el 68 % (46) de los pacientes presentaron exacerbaciones vs. el 46 % (31) de los pacientes en el PV (p 0,003). En el PP, se registraron 135 exacerbaciones totales vs. 79 en el PV (p 0,001); hubo una reducción del 41 %. En el PP, el 47 % (32) de los pacientes tuvieron exacerbaciones graves vs. el 32 % (22) de los pacientes en el PV (p 0,048). Hubo 91 exacerbaciones graves en el PP vs. 49 en el PV (p 0,029), reducción del 46 %. No hubo diferencias en las hospitalizaciones (PP 10, PV 6; p 0,9). La telemedicina fue efectiva para el seguimiento de pacientes con asma grave

During the COVID-19 pandemic, health care strategies were explored to ensure the follow-up of children with severe asthma. This was a prospective, observational, and comparative study. Patients in the severe asthma program of a tertiary care children's hospital were included (n: 74). The extent of control, exacerbations, and hospitalizations during an in-person period (IPP) (March 2019­2020) and an online period (OP) (April 2020­2021) was assessed. A total of 74 patients were enrolled in the IPP compared to 68 (92%) in the OP. During the IPP, 68% (46) of patients had exacerbations versus 46% (31) during the OP (p = 0.003). During the IPP, 135 total exacerbations were recorded compared to 79 during the OP (p = 0.001); this accounted for a 41% reduction. During the IPP, 47% (32) of patients had severe exacerbations versus 32% (22) during the OP (p = 0.048). A total of 91 severe exacerbations were recorded during the IPP compared to 49 during the OP (p = 0.029); the reduction was 46%. No differences were observed in terms of hospitalization (IPP: 10, OP: 6; p = 0,9). Telemedicine was effective for the follow-up of patients with severe asthma.

Sulfato de magnesio y aminofilina en el tratamiento de niños, niñas y adolescentes hospitalizados. Perfil de uso y respuesta terapéutica

Introducción: Sulfato de magnesio (MgSO4) y aminofilina son broncodilatadores intravenosos utilizados en el tratamiento de niños con broncoobstrucción (BO). La evidencia disponible para recomendar su uso es escasa. Objetivo: Caracterizar el perfil de uso y la respuesta terapéutica al MgSO4 y aminofilina en el tratamiento de la BO en niños hospitalizados en un centro de referencia de Uruguay. Materiales y métodos: Estudio descriptivo de corte transversal mediante revisión de historias y entrevistas. Se incluyeron a todos los menores de 15 años que utilizaron estos fármacos. Se evaluó la respuesta terapéutica a la administración de ambos fármacos en forma exclusiva y concomitante y la presencia de efectos adversos. Resultados: Se incluyeron 102 niños, mediana de edad 4 años, ≤5 años 62%. Los principales diagnósticos fueron: crisis asmática 56% y neumonía viral 31%. Recibieron ambos fármacos 48%, únicamente aminofilina 28% y exclusiva de MgSO4 24%. Se observó buena respuesta terapéutica a la administración: exclusiva de MgSO4 67%, consecutiva de MgSO4 y aminofilina 45% y exclusiva de aminofilina en 34%. En 38,2% se registró al menos un efecto adverso, 64% eran menores de 5 años, riesgo aumentado en 1,5 veces. Conclusiones: Se registraron variadas indicaciones, la mayoría en niños asmáticos y en un porcentaje menor indicaciones fuera de prospecto. Menos de la mitad presentaron buena respuesta luego de la administración de MgSO4 y/o aminofilina. En un porcentaje no despreciable se registraron efectos adversos, predominaron en menores de 5 años. Son necesarios nuevos estudios para continuar caracterizando el perfil de uso y seguridad de estos fármacos.

Introduction: Magnesium sulfate (MgSO4) and aminophylline are intravenous bronchodilators used in the treatment of children with bronchoobstruction (BO). The evidence available to recommend their use is scarce. Objective: To characterize the use profile and therapeutic response to MgSO4 and aminophylline in the treatment of BO in children hospitalized in a reference center in Uruguay. Materials and methods: This was a descriptive cross-sectional study through review of clinical histories and interviews. All children under 15 years of age who used these drugs were included. The therapeutic response to the administration of both drugs exclusively and concomitantly and the presence of adverse effects were evaluated. Results: 102 children were included, median age was 4 years, 62% were ≤5 years. The main diagnoses were: asthmatic crisis, 56% and viral pneumonia, 31%. 48% received both drugs, 28% only aminophylline and 24% exclusively MgSO4. Good therapeutic response was observed to the administration: MgSO4 exclusively, 67%, MgSO4 followed by aminophylline, 45% and aminophylline exclusively in 34%. At least one adverse effect was recorded in 38.2%, of these, 64% were under 5 years of age, risk increased by 1.5 times. Conclusions: Various indications were recorded, the majority in asthmatic children and a smaller percentage off-label indications. Less than half had a good response after the administration of MgSO4 and/or aminophylline. Adverse effects were recorded in a non-negligible percentage, predominating in children under 5 years of age. New studies are necessary to continue characterizing the use and safety profile of these drugs.

El objetivo de esta revisión es brindar una visión razonada de atención en el paciente comprometido sistémicamente, basados en protocolos internacionales, y una serie de pasos y modificaciones que deben ser consideradas al momento del manejo odontológico. Se realizó la búsqueda científica en bases digitales contemplando información en idiomas inglés y español, acerca del manejo del paciente dependiendo de su diagnóstico médico y sus complicaciones. Concluimos que el tratamiento dental de pacientes pediátricos con enfermedades sistémicas se puede llevar a cabo de manera eficiente en presencia de un equipo dental bien equipado y apoyo de los padres. Un dentista pediátrico juega un papel importante en el alivio de la ansiedad del niño, manteniendo una relación positiva y haciendo que los servicios de atención se conviertan en experiencias cómodas y libres de complicaciones para pacientes infantiles con enfermedades sistémicas de base, como cardiopatías y/o asma (AU)

This review provides a systematic approach to establishing safe, comprehensive, coordinated, and family-oriented dental care delivery for the child with medical complexities. We suggest that adopting an individualized, strength-based approach to evaluating children with complex medical conditions provides the surest basis for delivering care to heart disease and asthma patients. This review aims to provide a reasoned care approach for the patient with a systemic compromise based on international protocols and a series of steps and modifications that should be considered during dental management. A scientific search was conducted in digital databases, including information in English and Spanish, on managing patients according to their medical diagnosis and complications. We conclude that dental treatment of pediatric patients with systemic diseases can be carried out efficiently in the presence of a well-equipped dental team and parental support. A pediatric dentist plays a vital role in relieving the child's anxiety, maintaining a positive relationship, and making care services become comfortable and complication-free experiences for pediatric patients with underlying systemic diseases, such as heart disease and/or asthma (AU)

Guia prático para o uso de imunobiológicos em doenças alérgicas - ASBAI / Practical guide for the use of immunobiologic agents in allergic diseases - ASBAI

Os anticorpos monoclonais são uma nova classe de medicamentos que representa um marco na evolução da terapia de doenças alérgicas graves. Além de possibilitar uma terapia imunológica alvo específico, proporciona maior controle de sintomas, redução de exacerbações, melhoria da qualidade de vida e da segurança. A eficácia e a segurança dos anticorpos monoclonais no tratamento de doenças alérgicas estão bem documentadas nos estudos clínicos pivotais, de extensão e de vida real. No Brasil, estão licenciados atualmente pela Agência Nacional de Vigilância Sanitária (ANVISA) imunobiológicos para asma, dermatite atópica (DA), esofagite eosinofílica (EoE), granulomatose eosinofílica com poliangeíte (GEPA), rinossinusite crônica com pólipo nasal (RSCcPN), síndromes hipereosinofílicas (SHE) e urticária crônica espontânea (UCE). Com a incorporação do uso dessas novas terapias no dia a dia do médico alergologista e imunologista, naturalmente emergem aspectos práticos que exigem orientações práticas perante as evidências científicas mais atuais, a fim de se manter a boa prática médica, com uso criterioso e consciente pelo especialista capacitado. Assim, nesse guia prático, abordaremos os imunobiológicos aprovados até o momento para doenças alérgicas graves, com objetivo de auxiliar o especialista em Alergia e Imunologia na prescrição e manejo dessas medicações, incluindo indicações, contraindicações, monitoramento da eficácia e segurança, notificação de eventos adversos, bem como aspectos associados aos cuidados com vacinas, populações especiais, acesso, transporte, armazenamento e aplicação domiciliar.

Monoclonal antibodies are a new class of drugs that represent a milestone in the evolution of therapy for severe allergic diseases. In addition to allowing targeted immunologic therapy, they can improve symptom control, reduce exacerbations, and increase quality of life and safety. The efficacy and safety of monoclonal antibodies in the treatment of allergic diseases are well documented in pivotal, extension, and real-life clinical studies. In Brazil, immunobiologic agents are currently licensed by the National Health Surveillance Agency (ANVISA) for use in asthma, atopic dermatitis (AD), eosinophilic esophagitis (EoE), eosinophilic granulomatosis with polyangiitis (EGPA), chronic rhinosinusitis with nasal polyps (CRSwNP), hypereosinophilic syndrome (HES), and chronic spontaneous urticaria (CSU). With the incorporation of these new therapies into the daily practice of the allergist and immunologist, practical aspects will naturally emerge and require practical guidelines in light of the most current scientific evidence in order to maintain good medical practice, with judicious and conscious use by a qualified specialist. Therefore, in this practical guide, we will address the immunobiologic agents currently approved for severe allergic diseases, aiming to assist allergy and immunology specialists in the prescription and practical management of these medications, including indications, contraindications, efficacy and safety monitoring, adverse event reporting, as well as health care factors associated with vaccination, special populations, access, transport, storage, and home use.

Perfil etiológico, sociodemográfico e desfechos dos pacientes com asma internados por síndrome respiratória aguda grave (SRAG) no Brasil de 2020 a 2022: uma análise de 83.452 internações / Etiology, sociodemographic profile, and outcomes of patients with asthma hospitalized for severe acute respiratory illness (SARI) in Brazil from 2020 to 2022: an analysis of 83,452 hospitalizations Braian

Introdução: A asma é uma das doenças crônicas mais frequentes na população brasileira. O objetivo deste estudo foi determinar as etiologias, o perfil sociodemográfico e os fatores de risco para óbito entre pacientes com asma internados por síndrome respiratória aguda grave (SRAG) no Brasil entre 2020 e 2022. Métodos: A partir do banco de dados SIVEP-Gripe, incluímos todos os pacientes com idade maior que 5 anos registrados no banco de 01/01/2020 até 21/07/2022, hospitalizados por SRAG, com antecedente de asma e com desfechos conhecidos. Como exposições, foram estudadas a idade, sexo, região de moradia, etnia e agentes etiológicos virais isolados. Os desfechos foram internação em unidade de terapia intensiva, necessidade de ventilação mecânica e óbito. Para calcular a razão de chances entre exposição e desfechos, utilizamos modelos lineares generalizados mistos multinível. Resultados: Foram incluídas na análise 83.452 internações, sendo 14.062 crianças e adolescentes, e 69.390 adultos. A mortalidade aumentou com a idade, indo de 0,6% entre 5-10 anos para 33% nos maiores que 60 anos. Na população pediátrica, morar na região Norte e Nordeste e ter entre 10-20 anos foram associados a maior mortalidade (OR 2,14 IC95% 1,41- 3,24 e OR 3,73 IC95% 2,65-5,26 respectivamente). Quanto aos agentes etiológicos, apenas o SARS-CoV-2 conferiu maior risco de óbito (OR 5,18 IC95% 3,62-7,42). Entre adultos, sexo feminino e etnias não brancas foram protetoras (OR 0,87 IC95% 0,83-0,9 e OR 0,90; IC95% 0,85-0,94 respectivamente) para óbito. Faixas etárias mais avançadas, morar nas regiões Norte e Nordeste e o diagnóstico de COVID-19 foram associados a maior mortalidade. Conclusões: Há importantes vulnerabilidades sociodemográficas nos desfechos das internações de pacientes com asma por SRAG, com maior mortalidade nas regiões Norte-Nordeste, entre adolescentes na faixa etária pediátrica e entre idosos nos adultos. Além disso, destaca-se o protagonismo da COVID-19 entre as infecções associadas a maior mortalidade.

Introduction: Asthma is one of the most common chronic diseases affecting the Brazilian population. We aimed to determine the etiology, sociodemographic profile, and risk factors for death in patients with asthma hospitalized for severe acute respiratory illness (SARI) in Brazil from 2020 to 2022. Methods: We included all patients over 5 years of age registered in the Influenza Epidemiological Surveillance Information System (SIVEP Gripe) database of the Brazilian Ministry of Health from January 1, 2020 to July 21, 2022 hospitalized for SARI. Patients had to have a history of asthma and known outcomes. As exposures, age, sex, region of residence, ethnicity, and viral etiological agent were evaluated. The outcomes measured were admission to an intensive care unit, need for mechanical ventilation, and death. We used multilevel generalized linear mixed models to calculate the odds ratio between exposure and outcomes. Results: A total of 83,452 hospitalizations were included, of which 14,062 were children and adolescents and 69,390 were adults. Mortality increased with age, ranging from 0.6% in those aged 5-10 years to 33% in those over 60 years. In the pediatric population, living in the north and northeast regions (OR 2.14, 95%CI 1.41-3.24) and having between 10-20 years (OR 3.73, 95%CI 2.65-5.26) were associated with higher mortality. As for etiologic agents, only SARS-CoV-2 was associated with a higher risk of death (OR 5.18, 95%CI 3.62-7.42). Among adults, female sex (OR 0.87, 95%CI 0.83-0.9) and non-White ethnicities (OR 0.90, 95%CI 0.85-0.94) were protective factors against death. Older age groups, living in the north and northeast regions, and a diagnosis of COVID-19 were associated with higher mortality. Conclusions: There are important sociodemographic vulnerabilities in the outcomes of patients with asthma hospitalized for SARI, with higher mortality rates in the north and northeast regions, among adolescents in the pediatric age group, and among older adults. Furthermore, COVID-19 was one of the main infections associated with higher mortality.

Asma ocupacional: a propósito de un caso

Se presenta el caso de un trabajador de 31 años que desempeña tareas en un molino de granos desde hace 12 años y que ha desarrollado asma ocupacional. El objetivo del artículo es presentar los fundamentos utilizados para sostener el origen profesional del asma adquirido. Se describen las tareas laborales que desarrolla, materiales y medios de trabajo que utiliza. Se analiza en particular la exposición laboral a polvo orgánico y su vinculación temporal con la sintomatología respiratoria. Esta información permite comprender la importancia de las condiciones en las que realiza el trabajo y la exposición a un factor de riesgo, el polvo orgánico, para el desarrollo de la patología respiratoria laboral. Se realizaron mediciones de volumen máximo espiratorio pulmonar, con técnica de pico flujo, durante la jornada laboral y fuera de ésta. Se observaron variaciones del flujo espiratorio mayores a 20%, tanto durante la jornada laboral como fuera de ella, con similar patrón sintomático, según relata el trabajador. Se concluyó que existe evidencia del nexo causal entre el asma y el trabajo, por lo que se plantea el diagnóstico de asma ocupacional. Se destaca la importancia de evaluar los riesgos laborales en cada actividad para implementar planes de vigilancia de la salud, tanto del operario como del ambiente de trabajo, para prevenir la aparición como la evolución de esta u otras patologías que en muchos casos generan incapacidad para la tarea y deterioro de la calidad de vida de los trabajadores.

We present the case of a 31-year-old worker who has been working in a grain mill for 12 years and has developed work-related asthma. The objective of this article is to present the foundations used to support the occupational origin of the acquired asthma. The study describe the work tasks performed, the materials used, and the working methods. The work-related exposure to organic dust and its temporal relationship with respiratory symptoms is particularly analyzed. This information allows us to understand the importance of working conditions and exposure to organic dust, a risk factor, for the development of this work-related respiratory pathology. Measurements of maximum expiratory lung volume were made using the peak flow technique during and outside of the workday. Expiratory flow variations greater than 20% were observed, both during and outside of the workday, which followed a similar symptomatic pattern as reported by the worker. The study concluded that there is evidence of a causal link between asthma and work, thus suggesting the diagnosis of work-related asthma. The importance of assessing occupational risks in each activity to implement health surveillance plans for both workers and the work environment is highlighted, aiming to prevent the onset and progression of this and other pathologies that often result in work incapacity and deterioration of workers' quality of life.

Apresentamos o caso de um paciente de 31 anos de idade que trabalha em um moinho de grãos há 12 anos e desenvolveu asma ocupacional. O objetivo do artigo é apresentar a justificativa da origem ocupacional da asma adquirida. Descrevemos as tarefas realizadas, os materiais e os meios de trabalho utilizados. Analisamos especialmente a exposição ocupacional à poeira orgânica e sua conexão temporal com a sintomatologia respiratória. Essas informações nos permitem entender a importância das condições em que o trabalho é realizado e a exposição a um fator de risco, a poeira orgânica, para o desenvolvimento da patologia respiratória ocupacional. As medições do volume pulmonar expiratório máximo foram realizadas com a técnica de pico de fluxo durante e fora da jornada de trabalho. Observamos variações no fluxo expiratório superiores a 20%, tanto durante quanto fora do horário de trabalho, com um padrão sintomático semelhante ao relatado pelo trabalhador. Concluímos que há evidências de um nexo causal entre asma e trabalho e, portanto, propomos o diagnóstico de asma ocupacional. Destacamos a importância de avaliar os riscos ocupacionais em cada atividade para implementar planos de vigilância da saúde tanto do trabalhador quanto do ambiente de trabalho, a fim de evitar o surgimento e a evolução dessa ou de outras patologias que, em muitos casos, geram incapacidade para a tarefa e deterioração da qualidade de vida dos trabalhadores.

Paciente varón de tres años con sibilancias y tos crónica / Three-Year-Old Male with Wheezing and Chronic Cough

Se presenta el caso de un niño de 3 años con diagnóstico de asma, rinitis alérgica, características craneofaciales dismórficas e infecciones respiratorias altas y bajas recurrentes, manejado como asma desde un inicio. Como parte del estudio de comorbilidades, se decide realizar una prueba del sudor que sale en rango intermedio y más tarde se encuentra una mutación, donde se obtiene un resultado positivo para una copia que se asocia a fibrosis quística. Se revisará el caso, así como el diagnóstico, clínica y tratamiento del síndrome metabólico relacionado con el regulador de conductancia transmembrana de fibrosis quística (CRMS).

We present the case of a 3-year-old boy with a diagnosis of asthma, allergic rhinitis, dysmorphic craniofacial characteristics and recurrent upper and lower respiratory infections, managed as asthma from the beginning. As part of the study of comorbidi-ties, it was decided to carry out a sweat test that came out in the intermediate range and later one mutation was found, where a positive result was obtained for a copy that is associated with cystic fibrosis. The case will be reviewed, as well as the diagnosis, symptoms and treatment of the metabolic syndrome related to the cystic fibrosis trans-membrane conductance regulator (CRMS).

Cuidando do ambiente ­ Logística reversa e dispositivos inalatórios / Caring for the environment: reverse logistics and inhalation devices

A asma é uma das doenças crônicas mais prevalentes e representa um problema de saúde pública global que afeta mais de 300 milhões de pessoas em todo o mundo, com um aumento adicional estimado de 100 milhões até 2025. A asma é uma doença típica de origem ambiental com exposição a infeções, alérgenos, poluentes e outros fatores estressores implicados na sua patogênese. O impacto ambiental causado pelos dispositivos inalatórios é cada vez mais importante, e pouco abordado ou valorizado. Até 88% dos profissionais de saúde não têm conhecimento que os dispositivos de aerossol dosimetrado contêm gás propelente que afeta a camada de ozônio e causa aquecimento global. São necessárias estratégias alternativas de tratamento se quisermos evitar a piora das alterações climáticas. Portanto, diante desse cenário existem oportunidades de ouro para tornar o tratamento da asma mais eficaz, moderno, seguro e ecológico.

Asthma is one of the most prevalent chronic diseases and represents a global public health problem, affecting more than 300 million people worldwide, with an estimated additional increase of 100 million cases by 2025. Asthma is a textbook disease of environmental origin, with exposure to infections, allergens, pollutants, and other environmental stressors implicated in its pathogenesis. The environmental impact of inhalation devices is increasingly important and has been rarely addressed and undervalued. Up to 88% of healthcare professionals are unaware that metered-dose aerosol devices contain a propellant gas that affects the ozone layer and causes global warming. Alternative treatment strategies are needed if we are to avoid worsening climate change. Given this scenario, there are excellent opportunities to make asthma treatment more effective, modern, safe, and eco-friendly.

Maternal overweight and obesity before pregnancy as predictors of childhood asthma in children under five years: a retrospective cohort in Peru / Sobrepeso y obesidad materna antes del embarazo como predictores de asma infantil en menores de cinco años: una cohorte retrospectiva en Perú

Abstract Objectives: to estimate the role of maternal overweight and obesity before pregnancy as predictors of childhood asthma in a population of Peruvian children under five years. Methods: we carried out a retrospective cohort study of children aged five years or less and their mothers from the Regional Hospital of Ayacucho and the María Auxiliadora Hospital in Lima, Peru. We included children who were born between 2013 and 2014 and follow them up until 2018 and 2019, respectively. The diagnosis of overweight and obesity of the mother before pregnancy and asthma in the child were registered in their clinical histories. Crude (cRR) and adjusted relative risks (aRR) and 95% confidence intervals (CI95%) were obtained using a generalized lineal model of the Poisson family with link log and robust variances. Results: we evaluated 431 medical records and found that 20.9% of the children had asthma, 26.7% of the mothers were overweight, and 20.2% were obese before pregnancy. In the adjusted regression model, overweight (aRR=2.94; CI95%= 1.54-5.60) and maternal obesity (aRR=5.10; CI95%= 2.73-9.51) were predictors of an increased risk of childhood asthma. Conclusions: maternal overweight and maternal obesity increased the risk of her children developing asthma threeand five-fold, respectively.

Resumen Objetivos: estimar el papel del sobrepeso y la obesidad materna antes del embarazo como predictores de asma infantil en una población de niños peruanos menores de cinco años. Métodos: realizamos un estudio de cohorte retrospectivo de niños de cinco años o menos y sus madres del Hospital Regional de Ayacucho y del Hospital María Auxiliadora de Lima, Perú. Se incluyeron niños nacidos entre 2013 y 2014 y se les dio seguimiento hasta 2018 y 2019, respectivamente. El diagnóstico de sobrepeso y obesidad de la madre antes del embarazo y asma en el niño fueron registrados en sus historias clínicas. Los riesgos relativos crudos (cRR) y ajustados (RRa) y los intervalos de confianza del 95% (IC95%) se obtuvieron mediante un modelo lineal generalizado de la familia de Poisson con log de enlace y varianzas robustas. Resultados: se evaluaron 431 historias clínicas y se encontró que el 20,9% de los niños tenían asma, el 26,7% de las madres tenían sobrepeso y el 20,2% eran obesas antes del embarazo. En el modelo de regresión ajustada, el sobrepeso (aRR=2,94; IC95%= 1,54-5,60) y obesidad materna (RRa=5,10; IC95%= 2,73-9,51) fueron predictores de un mayor riesgo de asma infantil. Conclusiones: el sobrepeso materno y la obesidad materna aumentaron tres y cinco veces el riesgo de que sus hijos desarrollaran asma, respectivamente.

Disfunções respiratórias felinas: caracterizando e diferenciando a asma e bronquite felinas / Feline respiratory dysfunctions: characterizing and differentiating feline asthma and bronchitis / Disfunciones respiratorias felinas: caracterización y diferenciación del asma y bronquitis felinas

As doenças respiratórias são consideradas doenças graves e potencialmente deletérias. Dentre elas, a asma e a bronquite crônica caracterizam-se como disfunções respiratórias que ameaçam constantemente o bem-estar dos gatos. Os pacientes apresentam mudanças na estrutura respiratória, reversíveis ou não, devido ao extenso quadro inflamatório, que obstrui o fluxo de ar, permite o acúmulo de muco e reduz o lúmen das vias aéreas. Os gatos acometidos apresentam tosses, respiração ruidosa, dispneia, e, em muitos casos, assumem posição ortopneica. O diagnóstico pode ser obtido através de exames de rotina, uso de radiografias torácicas, coleta e análise de fluidos broncoalveolares, e testes alergênicos. O manejo terapêutico baseia-se, combinado ou não, no uso de drogas como broncodilatadores, antiinflamatórios esteroidais, mucolíticos, antibióticos, agentes inalatórios e mudanças ambientais com objetivo de redução da exposição aos possíveis agentes alergênicos responsáveis pela incitação do quadro respiratório.

Respiratory diseases are considered serious and potentially harmful diseases. Among them, asthma and chronic bronchitis are characterized as respiratory disorders that constantly threaten the well-being of cats. The patients present changes in the respiratory structure, reversible or not, due to the extensive inflammatory condition, which obstructs the air flow, allows the accumulation of mucus and reduces the lumen of the airways. Affected cats have coughs, wheezing, dyspnoea, and in many cases assume an orthopneic position. The diagnosis can be obtained through routine exams, use of chest x-rays, collection and analysis of bronchoalveolar fluids, and allergen testing. Therapeutic management is based, combined or not, on the use of drugs such as bronchodilators, steroidal anti-inflammatory, mucolytics, antibiotics, inhalational agents and environmental changes in order to reduce exposure to possible allergenic agents responsible for the incitation of the respiratory condition.

Las enfermedades respiratorias son consideradas enfermedades graves y potencialmente dañinas. Entre ellos, el asma y la bronquitis crónica se caracterizan por ser trastornos respiratorios que amenazan constantemente el bienestar de los gatos. Los pacientes presentan cambios en la estructura respiratoria, reversibles o no debido al cuadro inflamatorio extenso, que obstruye el flujo de aire, permite la acumulación de moco y reduce la luz de las vías respiratorias. Los gatos afectados presentan tos, respiración ruidosa, disnea y, en muchos casos, adoptan una posición ortopneica. El diagnóstico se puede obtener mediante exámenes de rutina, uso de radiografías de tórax, recolección y análisis de líquidos broncoalveolares, y pruebas de alérgenos. El manejo terapéutico se basa, combinado o no, en el uso de fármacos como broncodilatadores, antiinflamatorios esteroides, mucolíticos, antibióticos, agentes inhalatorios y cambios ambientales con el objetivo de reducir la exposición a posibles agentes alergénicos responsables de incitar la afección respiratoria.

Birth weight and asthma in young adults of a Brazilian birth cohort / Peso ao nascer e asma em adultos jovens de um coorte brasileiro de nascimentos

Abstract This article aims to evaluate the association between birth weight and asthma in adulthood, estimated by employing structural equation modeling. Cohort study with 1,958 participants aged 23-25 years from Ribeirão Preto, São Paulo, Brazil. Standardized questionnaires were applied and pulmonary function evaluated, including bronchial reactivity with methacholine. A theoretical model was proposed to explore the effects of birth weight and asthma in adulthood. Asthma, socioeconomic status at birth (Birth SES), and current socioeconomic status (Adult SES) were obtained by constructs. Maternal age, sex, skin color, body mass index (BMI), smoking, parental asthma history, history of respiratory infection before five years old, history of hospitalization for lung disease before two years old, and atopy were the studied variables. 14.1% of participants were diagnosed with asthma. Birth weight was associated with asthma (Standardized Coefficient - SCtotal=-0.110; p=0.030), and an indirect effect was also observed (SCindirect=-0.220; p=0.037), mediated by hospitalization before two years and respiratory infection before five years. Lower birth weight showed an increased risk of asthma in adulthood and the SES Birth and Adult SES variables underlie this association.

Resumo O objetivo deste artigo é avaliar associação entre peso ao nascer e asma na vida adulta pela análise de equações estruturais. Estudo de coorte com 1.958 participantes de 23-25 anos, residentes em Ribeirão Preto, São Paulo, Brasil. Foram aplicados questionários padronizados e avaliado a função pulmonar, incluindo hiper-reatividade brônquica com metacolina. O modelo teórico foi proposto para explorar os efeitos do peso ao nascer e asma na vida adulta. Asma, status socioeconômico ao nascimento (SES Nascimento) e status socioeconômico adulto (SES adulto) foram obtidos por um construto. Variáveis estudadas: idade materna, idade, sexo, cor da pele, índice de massa corporal (IMC), tabagismo, história de asma dos pais, história de infecção respiratória antes dos cinco anos, história de internação por doença pulmonar antes dos dois anos e atopia. 14,1% dos participantes foram diagnosticados com asma. Peso ao nascer foi associado com asma (Coeficiente Padronizado - CPtotal=-0,110; p=0,030), e foi observado efeito indireto (CPindireto=-0,220; p=0,037), mediado por internação antes dos dois anos e infecção respiratória antes dos 5 anos. Menor peso ao nascer aumentou o risco para asma na vida adulta e as variáveis SES Nascimento e SES adulto foram subjacentes a esta associação.

Overprescription of short-acting β2 agonists: reflections from the SABINA study in Brazil / Prescrição excessiva de β2-agonistas de curta duração: reflexões a partir do estudo SABINA no Brasil

ABSTRACT Objective: To assess prescription patterns for short-acting b2 agonists (SABAs) and other asthma medications in asthma patients treated by specialists and participating in the SABA use IN Asthma (SABINA) study in Brazil. Methods: This was an observational, cross-sectional study conducted at five sites in different regions of Brazil. The primary endpoints were to record SABA prescriptions and obtain data on over-the-counter (OTC) SABA purchases at the pharmacy. Results: Data on 218 asthma patients were analyzed. Of those 218 patients, 80.3% were prescribed SABAs in addition to their maintenance therapy, with a mean of 11.2 SABA canisters in the previous 12 months. Of those patients, 71.4% were prescribed ≥ 3 canisters and 42.2% were prescribed ≥ 10 canisters. None of the patients were prescribed SABA monotherapy. A total of 14.2% of the patients reported purchasing SABAs OTC at a pharmacy without a prescription. Of those, 48.4% purchased ≥ 3 SABA canisters. A fixed-dose combination of an inhaled corticosteroid and a long-acting b2 agonist was prescribed to 95.0% of the patients. In the year before the study visit, 45.0% of the patients received at least one course of oral corticosteroid burst treatment. Asthma was well controlled in 43.1% of the patients, partly controlled in 34.9%, and uncontrolled in 22.0%. Patients reported a mean of 1.1 severe asthma exacerbations, with 49.1% experiencing 1 or more severe exacerbations. Conclusions: Overprescription and OTC purchases of SABAs are common in Brazil, possibly leading to the need for courses of oral corticosteroids. The health care community should collaborate to implement evidence-based recommendations and promote health education to improve asthma management in Brazil.

RESUMO Objetivo: Avaliar os padrões de prescrição de short-acting b2 agonists (SABAs, b2-agonistas de curta duração) e outros medicamentos para asma em pacientes tratados por especialistas e participantes do estudo SABA use IN Asthma (SABINA) no Brasil. Métodos: Trata-se de um estudo transversal observacional realizado em cinco locais em diferentes regiões do Brasil. Os desfechos primários foram registrar as prescrições de SABAs e obter dados a respeito da compra de SABAs sem receita médica na farmácia. Resultados: Foram analisados dados a respeito de 218 pacientes com asma. Dos 218 pacientes, 80,3% receberam prescrição de SABA além da terapia de manutenção, com uma média de 11,2 frascos de SABA nos 12 meses anteriores. Destes, 71,4% receberam prescrição de ≥ 3 frascos e 42,2% receberam prescrição de ≥ 10 frascos. Nenhum dos pacientes recebeu prescrição de monoterapia com SABA. Do total de pacientes, 14,2% relataram que compraram SABAs sem receita médica na farmácia. Destes, 48,4% compraram ≥ 3 frascos de SABA. Foram prescritas doses fixas combinadas de corticosteroide inalatório e b2-agonista de longa duração para 95,0% dos pacientes. No ano anterior à visita do estudo, 45,0% dos pacientes receberam pelo menos um ciclo de tratamento de curta duração com corticosteroide oral. A asma estava bem controlada em 43,1% dos pacientes, parcialmente controlada em 34,9% e não controlada em 22,0%. Os pacientes relataram uma média de 1,1 exacerbações graves da asma, sendo que 49,1% apresentaram uma ou mais exacerbações graves. Conclusões: A prescrição excessiva e a compra de SABAs sem receita médica são comuns no Brasil e possivelmente levam à necessidade de uso de corticosteroides orais. A comunidade de profissionais de saúde deve colaborar para implantar recomendações baseadas em evidências e promover a educação em saúde para melhorar o manejo da asma no Brasil.

Telehealth for children and adolescents with chronic pulmonary disease: systematic review / Telessaúde para crianças e adolescentes com doenças pulmonares crônicas: revisão sistemática

Abstract Objective: To revise the impact of telehealth on the quality of life, reduction in pulmonary exacerbations, number of days using antibiotics, adherence to treatment, pulmonary function, emergency visits, hospitalizations, and the nutritional status of individuals with asthma and cystic fibrosis. Data source: Four databases were used, MEDLINE, LILACS, Web of Science and Cochrane, as well as manual searches in English, Portuguese and Spanish. Randomized clinical trials, published between January 2010 and December 2020, with participants aged 0 to 20 years, were included. Data synthesis: Seventy-one records were identified after the removal of duplicates; however, twelve trials were eligible for synthesis. Included trials utilized: mobile phone applications (n=5), web platforms (n= 4), mobile telemedicine unit (n=1), software with an electronic record (n=1), remote spirometer (n=1), and active video games platform (n=1). Three trials used two tools, including telephone calls. Among the different types of interventions, improvement in adherence, quality of life, and physiologic variables were observed for mobile application interventions and game platforms compared to usual care. Visits to the emergency department, unscheduled medical appointments, and hospitalizations were not reduced. There was considerable heterogeneity among studies. Conclusions: The findings suggest that better control of symptoms, quality of life, and adherence to treatment can be attributed to the technological interventions used. Nevertheless, further research is needed to compare telehealth with face-to-face care and to indicate the most effective tools in the routine care of children with chronic lung diseases.

RESUMO Objetivo: Revisar o impacto da telessaúde na qualidade de vida, redução das exacerbações pulmonares, número de dias em uso de antibióticos, adesão ao tratamento, função pulmonar, visitas à emergência, hospitalizações e estado nutricional de indivíduos com asma e fibrose cística. Fontes de dados: Foram utilizadas quatro base de dados, sendo, MEDLINE, LILACS, Web of Science e Cochrane, além de pesquisas manuais nos idiomas inglês, português e espanhol. Foram incluídos ensaios clínicos randomizados, publicados no período de janeiro de 2010 a dezembro de 2020, com participantes de 0 a 20 anos. Síntese dos dados: Setenta e um registros foram identificados após a remoção das duplicatas e doze estudos foram elegíveis para síntese. Os ensaios utilizaram aplicativos para celular (n=5), plataformas da web (n= 4), unidade de telemedicina móvel (n=1), software com registro eletrônico (n=1), espirômetro remoto (n=1) e plataforma ativa de videogames (n=1). Três ensaios utilizaram duas ferramentas, incluindo chamadas telefônicas. Entre os diferentes tipos de intervenções, observou-se melhora na adesão, qualidade de vida e de variáveis fisiológicas para intervenções de aplicativos móveis e plataformas de jogos em comparação com os cuidados habituais. Visitas ao pronto-socorro, consultas médicas não agendadas e internações não foram reduzidas. Houve considerável heterogeneidade entre os estudos. Conclusões: Os achados sugerem que a melhora do controle dos sintomas, da qualidade de vida e da adesão ao tratamento podem ser atribuídos às intervenções tecnológicas utilizadas. No entanto, mais pesquisas são necessárias para comparar a telessaúde com o atendimento presencial e indicar as ferramentas mais efetivas na rotina de cuidados à população infantil com doenças crônicas pulmonares.

Análisis comparativo de la Iniciativa Global para el Asma y las guías sudamericanas para el diagnóstico, manejo y prevención del asma en pacientes pediátricos

Fundamento: el asma es una enfermedad inflamatoria crónica con una alta prevalencia en Sudamérica, por lo que requiere un diagnóstico adecuado, manejo óptimo y medidas de prevención respaldados por evidencia científica constantemente actualizada. Objetivo: realizar un análisis comparativo entre la Iniciativa Global para el Asma y las guías sudamericanas para el diagnóstico, manejo y prevención del asma en pacientes pediátricos. Métodos: estudio de tipo observacional descriptivo que compara la guía Iniciativa Global para el Asma del año 2023 con guías nacionales de los países sudamericanos Colombia, Argentina, Chile, Uruguay, Venezuela y Perú, en los siguientes parámetros: recomendaciones diagnósticas, recomendaciones en el manejo y estrategias de prevención. Resultados: se encontraron diferencias en las recomendaciones de prevención y educación en las guías analizadas, mientras que la Iniciativa Global para el Asma y algunas guías sudamericanas mencionan medidas de prevención, otras guías no las mencionan o tienen información limitada al respecto. En los exámenes auxiliares, todas las guías mencionan la realización de espirometría para evaluar la función pulmonar, pero existen diferencias con la inclusión de otros exámenes, como el test de alergia o la medición de óxido nítrico exhalado. Conclusiones: se requiere una mayor estandarización y actualización de las guías sudamericanas para garantizar un manejo adecuado y consistente del asma en la región.

Foundation: Asthma is a chronic inflammatory disease with a high prevalence in South America, which requires proper diagnosis, optimal management and prevention measures supported by constantly updated scientific evidence. Objective: to carry out a comparative analysis between the Global Initiative for Asthma and the South American guidelines for the diagnosis, management and prevention of asthma in pediatric patients. Methods: descriptive observational study that compares the 2023 Global Initiative for Asthma guideline with national guidelines from the South American countries Colombia, Argentina, Chile, Uruguay, Venezuela and Peru, in the following parameters: diagnostic recommendations, management recommendations and prevention strategies. Results: differences were found in prevention and education recommendations in the guides analyzed, while the Global Initiative for Asthma and some South American guides mention prevention measures, other guides do not mention them or have limited information in this regard. In auxiliary tests, all guidelines mention performing spirometry to evaluate lung function, but there are differences with the inclusion of other tests, such as the allergy test or the measurement of exhaled nitric oxide. Conclusions: Greater standardization and updating of South American guidelines is required to guarantee adequate and consistent management of asthma in the region.

Beneficios que reciben los pacientes asmáticos tras la aplicación de un tratamiento fisioterapéutico y rehabilitador

El asma bronquial sigue siendo la enfermedad crónica más frecuente en la infancia. Su prevalencia continúa aumentando a pesar de que en la actualidad se disponen de eficaces manuales terapéuticos para el correcto manejo de los principales síntomas de la enfermedad. El tratamiento no farmacológico de este padecimiento se fundamenta en tres pilares esenciales: la educación sobre la enfermedad, las guías para profesionales y pacientes y la fisioterapia respiratoria. Los pacientes que tienen un tratamiento fisioterapéutico y rehabilitador de manera habitual, tienen una mejoría significativa en el control del asma, especialmente si estos se practican bajo la supervisión de un fisioterapeuta. Los beneficios que los pacientes asmáticos logran con la fisioterapia y la rehabilitación son numerosos y uno de los efectos más importante es el impacto positivo sobre la calidad de vida.

Bronchial asthma continues to be the most common chronic disease in childhood. Its prevalence continues to increase despite the fact that effective therapeutic manuals are currently available for the correct management of the main symptoms of the disease. The non-pharmacological treatment of this condition is based on three pillars: education about the disease, guides for professionals and patients, and respiratory physiotherapy. Patients who have regular physiotherapy and rehabilitation treatment have a significant improvement in asthma control, especially if these are practiced under the supervision of a physiotherapist. The benefits that asthmatic patients achieve with physiotherapy and rehabilitation are numerous and one of the most important effects is the positive impact on quality of life.

Evaluación del control del Asma en República Dominicana: una perspectiva clínica / Evaluation of Asthma Control in the Dominican Republic: a Clinical Perspective

Introducción: El asma es una patología respiratoria caracterizada por inflamación cró-nica y reversible de las vías aéreas. Esta se asocia con factores de riesgo modificables y no modificables que influyen sobre su control y exacerbaciones. En países como Puer-to Rico y Cuba, la prevalencia del asma es significativamente mayor a la global (22,8%, 23% y 6,6%, respectivamente).

Introduction: Asthma is a respiratory pathology characterized by chronic and reversible airway inflammation. It is associated with modifiable and non-modifiable risk factors that influence its control and exacerbations. In countries such as Puerto Rico (22.8 %) and Cuba (23 %), the prevalence of asthma is significantly higher than the global prevalence (6.6 %).

High-flow nasal cannula and non-invasive mechanical ventilation in pediatric asthma exacerbation: two-year prospective observational study in intensive care / Cánula nasal de alto flujo y ventilación no invasiva en asma pediátrico grave: estudio observacional prospectivo de dos años de duración en cuidados intensivos

Abstract Background: Asthma is a common cause of admission to the pediatric intensive care unit (PICU). We described and analyzed the therapies applied to children admitted to a tertiary PICU because of asthma. Later, we evaluated high-flow nasal cannula (HFNC) use in these patients and compared their evolution and complications with those who received non-invasive ventilation. Methods: We conducted a prospective observational study (October 2017-October 2019). Collected data: epidemiological, clinical, respiratory support therapy needed, complementary tests, and PICU and hospital stay. Patients were divided into three groups: (1) only HFNC; (2) HFNC and non-invasive mechanical ventilation (NIMV); and (3) only NIMV. Results: Seventy-six patients were included (39 female). The median age was 2 years and 1 month. The median pulmonary score was 5. The median PICU stay was 3 days, and the hospital stay was 6 days. Children with HNFC only (56/76) had fewer PICU days (p = 0.025) and did not require NIMV (6/76). Children with HFNC had a higher oxygen saturation/fraction of inspired oxygen ratio ratio (p = 0.025) and lower PCO2 (p = 0.032). In the group receiving both therapies (14/76), NIMV was used first in all cases. No epidemiologic or clinical differences were found among groups. Conclusion: HFNC was a safe approach that did not increase the number of PICU or hospital days. On admission, normal initial blood gases and the absence of high oxygen requirements were useful in selecting responders to HFNC. Further randomized and multicenter clinical trials are needed to verify these data.

Resumen Introducción: El asma es una causa frecuente de ingreso en la unidad de cuidados intensivos pediátricos (UCIP). En este, cuadro el uso de cánula nasal de alto flujo (CNAF) se ha visto extendido. En este trabajo se describe el tratamiento global en la UCIP ante el ingreso por asma en un hospital monográfico pediátrico y se evalúa la respuesta al uso de la CNAF, comparando la evolución de los pacientes con aquellos que recibieron ventilación no invasiva (VNI). Métodos: Se llevó a cabo un estudio observacional prospectivo (de octubre del 2017 a octubre del 2019). Se describieron epidemiología, clínica, tratamiento y soporte respiratorio. Para la comparación se crearon tres grupos de pacientes: 1) solo CNAF; 2) CNAF y VNI; y 3) solo VNI. Resultados: Se incluyeron 76 pacientes. La mediana de edad fue de dos años y un mes; la mediana de índice pulmonar fue 5. La mediana de ingreso en UCIP fue de tres días y de ingreso hospitalario, seis días. Los niños con solo CNAF (56/76) mostraron menos días de UCIP (p = 0.025) y no requirieron VNI (6/76). También mostraron mayor SatO2/FiO2 (saturación de oxígeno/fracción de oxígeno inspirado) (p = 0.025) y menor nivel de PCO2 (presión parcial de CO2) (p = 0.032). La VNI se utilizó primero siempre en el grupo que recibió ambas modalidades (14/76). No se encontraron diferencias epidemiológicas o clínicas entre grupos. Conclusiones: En nuestra serie, el uso de CNAF no aumentó los días de ingreso en la UCIP ni de hospital. Tampoco requirió cambio a VNI. Al ingreso, una gasometría normal y bajo requerimiento de oxígeno permitieron seleccionar a los pacientes respondedores. Se necesitan más ensayos multicéntricos clínicos aleatorizados para verificar estos datos.

Sensibilización cutánea a aero alérgenos en niños con rinitis y asma / Skin sensitization to aero-allergens in children with rhinitis and asthma

Introducción: Las enfermedades alérgicas son muy comunes en la población pediátrica. Entre las causas frecuentes se encuentran los aeroalérgenos del ambiente, y la identificación de estos es de gran ayuda tanto para el diagnóstico como para el tratamiento. Objetivos: Determinar la frecuencia de aeroalérgenos, por medio de la determinación de Inmunoglobulina E (IgE) específica a alérgenos comunes por la prueba de sensibilidad cutánea en pacientes pediátricos con síntomas de asma y rinitis alérgica. Materiales y Métodos: Diseño observacional, descriptivo, prospectivo, transversal, población de pacientes de 4 a 17 años con síntomas compatibles con asma y rinitis alérgica que acudieron a un centro asistencial pediátrico en el periodo de estudio. Se realizó por medio de las Pruebas de punción cutánea (PCP). Resultados: La edad media de los pacientes fue de 8 años, 57% pacientes de sexo masculino y 43% de sexo femenino. El 53% de los pacientes presenta rinitis y asma, 45% solo rinitis y el 2% solo asma. El 79% de los pacientes presentó reacción positiva de sensibilización alérgica por medio de la PCP. Teniendo en cuenta la sensibilización por tipo de aeroalérgenos se tuvo que el 64% de los pacientes tuvo reacción positiva a ácaros, 19% a animales 18% a cucarachas, 8% a pólenes y 6% a hongos. Conclusión: La gran mayoría de pacientes con asma padecía rinitis alérgica concomitante y los ácaros del polvo fueron los aeroalérgenos más frecuentemente determinados en las pruebas cutáneas de alergia en niños con asma y rinitis de nuestra población.

Introduction: Allergic diseases are very common in the pediatric population. Among the frequent causes are aeroallergens from the environment and the identification of these is a great help for diagnosis and treatment. Objectives: To determine the frequency of aeroallergens, through the determination of Immunoglobulin E (IgE) specific to common allergens by the skin sensitivity test in pediatric patients with symptoms of asthma and allergic rhinitis. Materials and Methods: Observational, descriptive, prospective, cross-sectional design, population of patients from 4 to 17 years old with symptoms compatible with asthma and allergic rhinitis who attended a pediatric care center during the study period. It was carried out by means of Skin Puncture Tests (PCP). Results: The mean age of the patients was 8 years, 57% male patients and 43% female. 53% of the patients presented Rhinitis and Asthma, 45% only Rhinitis and 2% only Asthma. 79% of the patients presented a positive allergic sensitization reaction through PCP. Taking into account the sensitization by type of aeroallergens, 64% of the patients had a positive reaction to mites, 19 % to animals 18% to cockroaches, 8% to pollens and 6% to fungi. Conclusion: The vast majority of patients with asthma suffered from concomitant allergic rhinitis and dust mites were the most frequently determined aeroallergens in allergic skin tests in children with asthma and rhinitis in our population.
