ABSTRACT
Abstract Objective To compare the effectiveness of inhaled Magnesium Sulfate associated with Salbutamol versus Inhaled Salbutamol alone in patients with moderate and severe asthma exacerbations. Method Clinical, prospective and randomized study with patients between 3 and 14 years of age divided into two groups: one to receive inhaled salbutamol associated with magnesium sulfate (GSM), the other to receive inhaled salbutamol alone (GS). The sample consisted of 40 patients, 20 patients in each group. Severity was classified using the modified Wood-Downes score, with values between 4 and 7 classified as moderate and 8 or more classified as severe. Results Post-inhalation scores decreased both in patients who received salbutamol and magnesium and in those who received salbutamol alone, with no statistically significant difference between the groups. Conclusions Despite the benefits when administered intravenously, inhalation of the drug alone or in combination did not reduce the severity of the exacerbation.
ABSTRACT
Las experiencias adversas en la infancia (EAI) tienen un impacto considerable en la salud física y mental de los niños y adolescentes. Esta revisión bibliográfica se centra en la asociación entre estas experiencias y la incidencia de síntomas asmáticos, así como en las alteraciones inmunológicas en la población pediátrica. Los estudios revisados muestran una correlación significativa entre la exposición a EAI y el asma, destacando la importancia de un enfoque biopsicosocial para su manejo. Además, se discuten las implicancias clínicas y las precauciones necesarias al interpretar estos hallazgos.
Adverse childhood experiences (ACEs) have a significant impact on the physical and mental health of children and adolescents. This literature review focuses on the association between these experiences and the incidence of asthma symptoms, as well as immunological alterations in the pediatric population. The reviewed studies show a significant correlation between ACE exposure and asthma, highlighting the importance of a biopsychosocial approach for its management. Additionally, the clinical implications and necessary precautions when interpreting these findings are discussed.

Resumen El aparato respiratorio, desde la nariz al pulmón, se comporta como una unidad anatómica y fisiopatológica bajo un modelo holístico. Se han observado alteraciones pulmonares sin traducción clínica en pacientes con rinitis sin asma, que se manifiestan como hiperreac tividad bronquial, reducción de la función pulmonar e inflamación bronquial. Estas serían consecuencia de un fenómeno inflamatorio sistémico con impacto simultá neo en nariz y pulmón, que por razones desconocidas no tiene una expresión clínica completa, pero que podrían significar un mayor riesgo de desarrollo de asma. En esta revisión abordamos la frecuencia y caracte rísticas de las anormalidades pulmonares existentes en niños y adolescentes con rinitis crónica derivadas de nuestras investigaciones previas y, más recientemente, del proyecto "Enfermedad Alérgica Respiratoria: El Con cepto de Unidad de la Vía Aérea", línea de investigación acreditada por la Universidad Católica de Córdoba y un análisis comparativo con las evidencias aportadas por otros autores en la literatura médica.
Abstract The respiratory tract, from the nose to the lung, behaves as an anatomical and pathophysiological unit under a holistic model. Lower airway abnormalities, such as bronchial hyperresponsiveness, reduced lung function and inflammation of the bronchial mucosa without clinical expression, have been observed in pa tients with rhinitis without asthma. These would be the consequence of a common systemic inflammatory phenomenon with simultaneous impact on the nose and lung. For unknown reasons, these patients do not exhibit a full clinical expression, which could mean an increased risk of developing asthma. In this review we address the frequency and charac teristics of existing pulmonary abnormalities in children and adolescents with chronic rhinitis that derive from our previous research and, more recently, within the project "Allergic Respiratory Disease: The United Airway Con cept" supported by the Universidad Católica de Córdoba, and a comparative analysis with the evidence provided by other authors in the medical literature.
ABSTRACT
Background: Allergic respiratory maladies, particularly pediatric asthma, pose substantial challenges in public health. This cross-sectional investigation endeavours to unravel the eosinophilic landscape within nasal cytological specimens and peripheral blood samples of pediatric asthma cohorts, with a keen focus on discerning the correlation between nasal and systemic eosinophilia.Methods: Sixty-six pediatric asthma subjects, aged 6 to 18, under the care of Cheluvamba hospital in Mysuru, were meticulously recruited over an extensive 18-month period.Results: Analysis unveiled a conspicuous preponderance of male participants, with a mean age range spanning 9 to 13 years. Intriguingly, the presence of allergic rhinitis (AR) exhibited no discernible statistically significant nexus with either asthma severity or eosinophilic markers. Noteworthy findings include peripheral eosinophilia detected in 56% of subjects, juxtaposed against nasal eosinophilia observed in 20%; however, no statistically meaningful correlation emerged between nasal and peripheral eosinophilia.Conclusions: The inquiry culminated in a robust affirmation that mean nasal eosinophil count and blood absolute eosinophil count (AEC) exhibit a salient association with asthma severity and control in pediatric cohorts, irrespective of AR presence. Particularly, a discernible augmentation in mean AEC and nasal eosinophil count was discerned concomitant with exacerbating asthma severity and in cases of partial/ uncontrolled asthma.
ABSTRACT
Background: Asthma is common chronic diseases among children. The impact of asthma in children depends on complex interactions between disease severity, reaction of children towards disease, treatment efficiency, social roles, and social environment. This study aims to assess the level of knowledge, the common misconceptions and the common attitudes and practices prevalent among parents of asthmatic children, which can help paediatricians in educating parents and the public about the disease.Methods: It was hospital based cross sectional study. Parents with bronchial asthmatic children between 3 and 12 years of age were interviewed based on predefined criteria. A proforma was used to collect data of parents and disease history of children. The 45-item questionnaire with three domains: knowledge, attitude, practice of bronchial asthma was scored. Higher scores indicated better KAP.Results: Out of 90 respondents, 64.4% had poor knowledge and 35.6% had good knowledge. About 44.4% respondents had negative attitude and 81.1% had poor practice.There was a poor attitude on the usage of asthma controller medication and the time of stoppage of the medicines. Overall, the attitude was on an average scale in more than 50.0% of the respondents.Conclusions: Around 2/3rd parents had poor knowledge and negative attitude and ? had poor practice. There was a significant association for the severity and duration of the disease with the knowledge and practice There was a significant conversion of good knowledge to practice.
ABSTRACT
Resumen Introducción. El asma es una enfermedad crónica que afecta a millones de personas en todo el mundo. La calidad del aire es uno de los factores clave que puede desencadenar los síntomas del asma. Objetivo. Analizar la calidad del aire y su relación con el asma en habitantes de grandes altitudes en La Paz (Bolivia). Materiales y métodos. Se desarrolló un estudio analítico, descriptivo y retrospectivo. Se recolectaron datos de pacientes con diagnóstico de asma en el Instituto Nacional del Tórax y en el Instituto Boliviano de Biología de Altura. Además, se monitoreó la calidad del aire y su material particulado en las estaciones de la "Red de monitoreo de la calidad del aire". Resultados. El 56,9 % de los casos fueron mujeres del Instituto Nacional del Tórax y el 45,7 % del Instituto Boliviano de Biología de Altura. En ambas instituciones, la media de edad fue de 47 años y los pacientes presentaban sobrepeso u obesidad. Se registraron incrementos de material particulado fino (PM2,5) en otoño, invierno y primavera, en 2014, 2016-2019 y en las cuatro estaciones del 2015. El material particulado inhalable grueso (PM10) se incrementó en otoño e invierno del 2014 al 2020, dentro de los límites establecidos. Se observó una asociación positiva y significativa entre la concentración de material particulado PM2,5 y los parámetros espirométricos de capacidad vital forzada, flujo espiratorio máximo y el porcentaje de reversión. La relación de partículas PM10 y los parámetros espirométricos de capacidad vital forzada, volumen espiratorio máximo en el primer segundo y flujo espiratorio máximo, también fue estadísticamente significativa. Conclusión. Los casos de asma se presentaron en promedio a los 47 años y en personas con sobrepeso u obesidad. Se observó una asociación positiva entre el material particulado, PM2,5 y PM10, con los parámetros espirométricos, la cual fue más marcada con las partículas PM2,5.
Abstract Introduction. Asthma is a chronic disease affecting millions of people around the world. Air quality is a major factor in triggering asthma symptoms. Objective. To analyze air quality and asthma in high-altitude residents of La Paz, Bolivia. Materials and methods. In this analytical, descriptive, and retrospective study, we collected data from patients diagnosed with asthma at the Instituto Nacional del Tórax and the Instituto Boliviano de Biología de Altura. In addition, air quality monitoring of particulate matter was carried out at the stations of the Red de Monitoreo de la Calidad del Aire. Results. Women represented 56.9% of cases at the Instituto Nacional del Tórax and the Instituto Boliviano de Biología de Altura. In both institutions, the average age was 47 years and patients were overweight or obese. Increases in PM2.5 were recorded in autumn, winter and spring from 2014, 2016 to 2019 and 2015 in all four seasons. PM10 showed increases in autumn and winter from 2014 to 2020 within the established limits. We observed a positive and significant association between PM2,5 concentration and the spirometry parameters of forced vital capacity, peak expiratory flow,, and "reversibility percentage" or "bronchodilator response percentage". The association of PM10 and forced vital capacity, forced expiratory volume in the first second, and peak expiratory flow, was also statistically significant. Conclusion. Asthma cases occur on average at 47 years of age in overweight or obese people. We observed a positive association between particles PM2,5 and PM10 with spirometric parameters, stronger with particulate matter PM2,5.
ABSTRACT
RESUMEN Objetivo: Comparar las reconsultas por asma al servicio de urgencias (SU) durante la semana posterior al alta y explorar los factores asociados antes y después de la implementación de un protocolo asistencial. Materiales y métodos: Se realizó un estudio de cohorte retrospectivo que incluyó las consultas por crisis asmática de adultos al SU de un hospital universitario en los períodos 2016-2018 (preprotocolo) y 2019-2020 (posprotocolo). Se utilizó un modelo de regresión logística multivariado y se reportaron odds ratios (OR) e intervalo de confianza del 95 % (IC 95 %). Se consideró significativo un valor p < 0,05. Resultados: Las reconsultas fueron 38 (31,40 %) para el período preprotocolo y 33 (26,61 %) para el período posprotocolo. En el modelo de regresión multivariable, no se encontraron diferencias en las reconsultas tempranas al comparar el período posprotocolo con el período preprotocolo (OR 0,68; IC 95 %: 0,26-1,74; p = 0,421). Los factores asociados a las reconsultas tempranas fueron la edad (OR: 1,02; IC 95 %: 1,00-1,04; p = 0,017), el sexo masculino (OR 0,21 IC 95 %: 0,08-0,59; p = 0,003) y el haber tenido más de una consulta al SU en el último año (OR 6,19 IC 95 %: 2,48-15,46; p < 0,001). Conclusión: Aunque las reconsultas tempranas no disminuyeron luego de la aplicación del protocolo, se identificaron la edad y el haber tenido más de una visita al SU por asma dentro del último año como factores de riesgo para las reconsultas dentro de la semana, mientras que el sexo masculino resultó ser un factor protector.
ABSTRACT Objective: To compare revisits for asthma to the emergency department (ED) during the week following discharge and describe associated factors before and after the implementation of an assistance protocol. Materials y methods: A retrospective cohort study was conducted, including visits for asthma exacerbations in adults to the ED of a university hospital during the periods 2016-2018 (pre-protocol) and 2019-2020 (post-protocol). A multivariate logistic regression model was used, and the odds ratios (OR) with their 95% confidence intervals (95 % CI) were reported. A p-value < 0.05 was considered significant. Results: Revisits were 38 (31.40 %) for the pre-protocol period and 33 (26.61%) for the post-protocol period. In the multivariate regression model, no differences were found in early revisits when comparing the post-protocol period with the pre-protocol period (OR 0.68; 95 % CI: 0.26-1.74; p = 0.421). Factors associated with early revisits were age (OR: 1.02; 95 % CI: 1.00-1.04; p = 0.017), male sex (OR: 0.21; 95 % CI: 0.08-0.59: p = 0.003), and having had more than one visit to the ED in the last year (OR: 6.19; 95 % CI: 2.48-15.46; p < 0.001). Conclusion: Although early revisits did not decrease after the protocol implementation, age and having had more than one visit for asthma to the ED in the last year were identified as risk factors for revisits within the week, while male sex was a protective factor.
ABSTRACT
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.

Esta revisión ofrece un enfoque sistemático para establecer una prestación de atención dental segura, integral, coordinada y orientada a la familia del niño con complejidades médicas. Sugerimos que adoptar un enfoque individualizado basado en la fortaleza para la evaluación de niños con afecciones médicas complejas ofrece la base más segura para la prestación de atención en pacientes con enfermedad cardiaca y asma. 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)

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.

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.

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.
ABSTRACT
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.

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.

OBJETIVO: A relação entre exposição ambiental e risco à saúde é amplamente reconhecida e a avaliamos em cinco países da América Latina com condições culturais distintas, mas com Índices de Desenvolvimento Humano semelhantes. MÉTODOS: Estudo transversal envolvendo 3.016 indivíduos (18 a 75 anos) oriundos de: Argentina (n = 878), Brasil (n = 1.030), México (n = 272), Paraguai (n = 508) e Peru (n = 328). A seleção foi aleatória e todos responderam questionário padronizado (fatores sociodemográficos, fatores ambientais e hábitos de vida) derivado do Clinical Screening Tool for Air Pollution Risk. Segundo o estado atual de saúde, foram categorizados em: saúde regular/má/péssima ou excelente/boa. Tendo-a como desfecho, realizou-se análise multivariada.Os dados foram apresentados como razão de verossimilhança (RV) e intervalos de confiança de 95% (IC 95%), tendo-se 5% o nível de significância. RESULTADOS: Foram significantemente associados a pior percepção de situação de saúde: morar em qualquer um dos países, ter umidade na residência (OR = 1,68; IC 95%: 1,33-2,12), dirigir automóvel com janelas abertas (OR = 1,31; IC 95%: 1,03-1,65), ter baixa renda familiar (OR = 1,59; IC 95%: 1,26-2,01), nível educacional incompleto (OR = 1,54; IC 95%: 1,22-1,94), histórico pessoal/familiar de hipertensão arterial (OR = 2,25; IC 95%: 01,64-3,09), doença pulmonar obstrutiva crônica/asma (OR = 1,74; IC 95%: 1,28-2,36), diabete melito (OR = 3,74; IC 95%: 2,23-6,29), obesidade (OR = 1,84; IC 95%: 1,84-3,19) ou comorbidades oftalmológicas (OR = 1,89; IC 95%: 1,55-2,30); realizar exercícios ao ar livre (OR = 1,60; IC 95%: 1,31-1,96). CONCLUSÕES: Apesar das diferentes exposições a que foram submetidos, alguns fatores permanecem muito significativos, e ter baixa renda familiar, expor-se à poluição e ter antecedentes de doenças crônicas foram associados à percepção de condição ruim de saúde.
OBJECTIVE: The relationship between environmental exposure and health outcomes is well known.We investigated this relationship in five Latin American countries with different cultural backgrounds but similar Human Development Indexes. METHODS: This was a cross-sectional study involving 3,016 individuals (18 to 75 years old) from Argentina (n=878), Brazil (n=1030), Mexico (n=272), Paraguay (n=508), and Peru (n=328). Participants were randomly selected and responded to a standardized questionnaire (including sociodemographic and environmental factors and lifestyle habits) derived from a clinical screening tool for air pollution risk. Based on their current health status, participants were categorized as having regular/bad/very bad or excellent/good health. Multivariate analysis was conducted, and data were presented as likelihood ratios and 95% confidence intervals (95%CI).The significance level was set at 5%. RESULTS: Living in any of the study countries; indoor humidity (OR=1.68; 95%CI: 1.33-2.12); driving with the windows open (OR=1.31; 95%CI: 1.03-1.65); low family income (OR=1.59; 95%CI: 1.26-2.01); incomplete education (OR=1.54; 95%CI: 1.22-1.94); personal/family history of hypertension (OR=2.25; 95%CI: 01.643.09), chronic obstructive pulmonary disease/asthma (OR=1.74; 95%:CI: 1.28-2.36), diabetes (OR=3.74; 95%CI:2.23-6.29), obesity (OR=1.84; 95%CI: 1.84-3.19), or ocular comorbidities (OR=1.89; 95%CI: 1.55-2.30); and exercising outdoors (OR=1.60; 95%CI: 1.31-1.96) were significantly associated with a worse perceived health status. CONCLUSIONS: Despite the different exposures to which participants were subjected, some factors remain very significant. Low family income, exposure to pollution, and a history of chronic diseases were associated with the perception of a poor health condition.

INTRODUÇÃO: A asma brônquica é uma doença crônica inflamatória de alta frequência mundialmente, e em especial no Brasil, onde ocorreram mais de 100.000 internações por ano, segundo dados do DATASUS. Identificar pacientes em admissão hospitalar que poderão necessitar de leito em UTI ou uso de ventilação mecânica por conta de crises asmáticas é um desafio ao profissional de saúde, portanto, faz-se importante analisar variáveis clínicas que possam predispor agravos e avaliar pacientes mais vulneráveis, para que as condutas realizadas sejam efetivas e rápidas. OBJETIVO: Analisar o perfil clínico e epidemiológico de pacientes internados em um hospital do sul do Brasil e avaliar os preditores relacionados ao maior tempo de internação. MÉTODOS: Estudo epidemiológico observacional, do tipo transversal, que utilizou como fonte de informação dados secundários, os quais foram obtidos através de prontuários de pacientes internados em um hospital do sul do Brasil. RESULTADOS: Foram analisados 261 prontuários. Verificou-se que a população menor de 40 anos de idade teve maior prevalência, representando 57% das internações. Além disso, em relação a gênero e etnia, mulheres e caucasianos foram as populações com maiores taxas de hospitalização, sendo 63% e 87% das admissões hospitalares, respectivamente.A necessidade de internação em UTI foi encontrada em 1,1% dos casos (3 pacientes), cerca de 6,9% tiveram internações prolongadas (maiores de 3 dias), e 0,8% vieram à óbito (2 pacientes). Identificou-se que a baixa saturação de oxigênio e a alta frequência cardíaca tiveram relação significativa com internação prolongada. CONCLUSÃO: É importante analisar sinais vitais no momento das admissões hospitalares e o perfil epidemiológico dos pacientes para que as populações mais prevalentes e os fatores preditivos de desfechos mais graves possam ser acompanhados e a conduta a ser tomada seja adequada e efetiva.
INTRODUCTION: Bronchial asthma is a chronic inflammatory disease with a high worldwide frequency, especially in Brazil, where more than 100,000 asthma-related hospitalizations occur annually according to DATASUS data. Identifying patients upon hospital admission who may require an ICU bed or mechanical ventilation due to an asthma attack is a challenge for healthcare professionals. It is important to analyze clinical variables that may predispose to deterioration and evaluate more vulnerable patients to ensure that effective interventions are instituted promptly. OBJECTIVE: To analyze the clinical and epidemiological profile of patients admitted due to asthma in a hospital in southern Brazil and evaluate predictors of longer hospital stay. METHODS: Observational epidemiological study with a cross-sectional design.The source of information were secondary data obtained from medical records of patients admitted to a hospital in southern Brazil. RESULTS: Overall, 261 medical records were analyzed.Patients were predominantly under the age of 40, representing 57% of hospitalizations. In terms of gender and ethnicity, most patients were female (63%) and white (87%).Three patients (1.1%) required ICU admission, approximately 6.9% had prolonged hospitalizations (>3 days), and 2 (0.8%) died. Low oxygen saturation and elevated heart rate correlated significantly with prolonged hospitalization. CONCLUSION: Vital signs at the time of hospital admission and the epidemiological profile of patients should be analyzed, so that the most prevalent populations and predictors of severe outcomes can be monitored, and appropriate and effective measures can be taken.

Childhood asthma, which is a chronic respiratory condition, presents challenges in terms of its complications, management, and identification of environmental triggers. This review of existing literature explores the complexities surrounding asthma. It delves into complications, strategies for managing the condition, and the crucial role that environmental factors play in worsening it. Uncontrolled asthma in children has far-reaching consequences as it affects lung function, physical activity levels, and overall quality of life. Early recognition and addressing of these complications are essential to minimize long-term effects. The management of childhood asthma has evolved to focus on treatment plans, with corticosteroids being a key component. For cases, advanced therapeutic options like biologics are available. Indoor and outdoor environmental triggers have an impact on asthma exacerbations, making targeted preventive measures necessary. Education plays a role by providing caregivers and children with asthma action plans as well as proper inhaler technique guidance. Regular follow-up visits ensure assessment and adjustment of treatment plans while fostering a relationship between healthcare providers and families. Comprehensive care for childhood asthma involves an approach that includes pediatricians, pulmonologists, allergists, and respiratory therapists. The triad of interventions, environmental modifications, and educational strategies forms an encompassing framework for the management of asthma. This review highlights how crucial it is to tackle childhood asthma issues. By doing so, we can improve outcomes. Promote the overall well-being of children who are affected by this condition.
ABSTRACT
Background: Asthma is associated with high morbidity and mortality in India. This survey was undertaken to explore the perspectives of pulmonologists towards in-clinic management of patients with asthma. Methods: It was a cross-sectional survey of pulmonologists conducted across India. It was formulated to provide unbiased observations of real-world clinical practice focusing on methods of diagnosis of asthma and its treatment preferences. Results: The participants included 805 pulmonologists, with the majority primarily treating patients with asthma (62%), chronic obstructive pulmonary disease (19%) and allergic rhinitis (19%). More than 86% of pulmonologists consider clinical symptoms, history of childhood asthma, family history, and chronic allergic rhinitis for initial diagnosis. About 19-23% prefer spirometry alone or in combination with family history for confirmation of asthma. The preferred inhaled corticosteroids-long-acting bronchodilator (ICS-LABA) combination was budesonide-formoterol amongst 83% of pulmonologists. For both dry powder inhaler (DPI) and metered dose inhaler (MDI) devices, fine particle fraction per cent and delivered dose were ranked as the two most important attributes. Conclusions: Asthma is the most prevalent diagnosis among patients treated by pulmonologists on the basis of clinical presentation and medical history. The most commonly used pharmacotherapy for the treatment of asthma comprises ICS-LABA, with budesonide-formoterol being the preferred combination. Fine particle fraction per cent and magnitude of delivered dose influence the choice of asthma inhaler prescriptions the most.
ABSTRACT
ObjectiveTo investigate the possible mechanism of Guben Fangxiao Beverage (固本防哮饮) for the prevention and treatment of chronic airway inflammation during asthma remission. MethodsThirty-six female Balb/c mice were randomly divided into normal group, model group, low-, medium-, and high-dose of Guben Fangxiao Beverage group and montelukast sodium group, with 6 mice in each group. Except for the normal group, ovalbumin and respiratory syncytial virus were used in other groups to establish a mouse model of bronchial asthma in remission stage. After molding, the low-, medium-, and high-dose groups of Guben Fangxiao Beverage were respectively given 12, 24, and 36 g/(kg·d), the montelukast sodium group was given montelukast sodium granule 2.6 mg/(kg·d), and the mice in the normal group and model group were given 20 ml of double-distilled water, all by gavage, once a day for 28 days. The levels of interleukin 4 (IL-4) and interleukin 5 (IL-5) in the lung tissue of mice were detected; HE staining was used to observe the pathology of the lung tissue and to score the inflammation; DHE staining was used to observe the level of reactive oxygen species (ROS) in the lung tissue, and the activities of mitochondrial respiratory chain complexes Ⅰ, Ⅱ, Ⅲ, Ⅳ, and Ⅴ in the lung tissue were detected; the levels of serum superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA) and adenosine triphosphate (ATP) were detected; the protein expression levels of phosphorylated adenosine monophosphate-activated protein kinase (p-AMPK), nuclear factor erythroid 2-related factor 2 (Nrf2), haem oxygenase 1 (HO-1) and cAMP responsive element binding protein (CREB) in the lung tissues of the model group were detected by Western blot. ResultsCompared with the normal group, the histopathological results of the lungs of mice in the model group showed an increase in inflammatory cells around the airways and an increase in inflammatory score; DHE staining showed an increase in the level of ROS, and an increase in the levels of IL-4 and IL-5 in the lung tissues; the levels of serum SOD, CAT, and ATP were reduced, and the level of MDA was elevated; the activities of the mitochondrial respiratory chain complexes Ⅰ, Ⅱ, Ⅲ, Ⅳ, and Ⅴ of the lung tissues were reduced, and the activities of p-AMPK, Nrf2, CREB protein expression decreased (P<0.05). Compared with the model group, the lung tissue inflammatory cells and inflammation scores of mice in each Guben Fangxiao Beverage dose group and montelukast sodium group were reduced; the levels of ROS, IL-4 and IL-5 in the lung tissue were reduced; the levels of CAT and ATP in the serum increased, and the content of MDA was reduced; and the activities of mitochondrial respiratory chain complexes Ⅰ and Ⅱ, as well as the expression of CREB protein, were elevated in the lung tissue (P<0.05). Compared with the high-dose group, the MDA level of the medium-dose Guben Fangxiao Beverage group decreased (P<0.05). The activity of mitochondrial respiratory chain complex V in the medium-dose group was higher than that in the montelukast sodium group, and the activity of mitochondrial respiratory chain complex Ⅳ in the medium- and high-dose groups was higher than that in the low-dose group (P<0.05). ConclusionGuben Fangxiao Beverage can inhibit oxidative stress and improve mitochondrial function to relieve chronic airway inflammation in bronchial asthma model mice during asthma remission, and its mechanism may be related to the activation of AMPK/Nrf2/HO-1 signaling pathway.
ABSTRACT
Cough variant asthma (CVA) is a chronic respiratory disease with cough as its main symptom. The occurrence of CVA is closely related to non-specific airway inflammation, and its pathogenesis involves environmental, genetic, immune, and other factors. In recent years, the advantages of traditional Chinese medicine (TCM) in the treatment of CVA have attracted the attention of experts and scholars in China and abroad, especially its prominent role in regulating immune balance, relieving cough symptoms in CVA patients, and reducing recurrence. T Helper cells 1 (Th1), T helper cells 2 (Th2), T helper cells 17 (Th17), and regulatory T cells (Treg) are derived from CD4+ T cells. Immune imbalance of Th1/Th2 and Th17/Treg is a new hotspot in the pathogenesis of CVA and a potential key target in the treatment of CVA by TCM. Th cell subsets are in dynamic balance under physiological conditions, maintaining respiratory immune homeostasis in which pro-inflammatory cytokines and anti-inflammatory cytokines are balanced. Immature helper T cells (Th0) can be differentiated into Th1, Th2, Th17, Treg, and other cell subsets due to cytokine types in the microenvironment in the stage of CVA maturation. The proliferation of Th2 cells leads to eosinophilic airway inflammation. Excessive differentiation of Th17 cells induces neutrophil airway inflammation. Th1/Th2 and Th17/Treg cells are mutually restricted in number and function, and the immune imbalance of Th1/Th2 and Th17/Treg is easy to aggravate the generation of inflammatory response. Restoring immune balance is particularly important for the airway anti-inflammatory therapy of CVA. In this paper, the imbalance of Th1/Th2 and Th17/Treg and the pathogenesis of CVA were systematically expounded. Meanwhile, the latest research on the regulation of immune imbalance by TCM compound, single TCM, and its effective ingredients in the treatment of CVA was reviewed. It provides ideas and references for revealing the scientific connotation of TCM regulating immune balance therapy of CVA, as well as the development of clinical treatment and basic research of CVA.
