RESUMO Objetivo Investigar o nível de conscientização sobre imunodeficiências primárias entre os médicos do Instituto Nacional de Salud del Niño. Métodos Estudo transversal com todos os residentes de pediatria e pediatras que faziam parte do corpo clínico do Instituto Nacional de Salud del Niño quando o estudo foi realizado (2017-2019). Médicos atuantes na unidade de imunologia e nos setores de cirurgia foram excluídos. Foram estudados três aspectos da conscientização sobre imunodeficiências primárias: educação, conhecimento geral e suspeita diagnóstica e ações adotadas frente à suspeita. Resultados A amostra foi composta por 83 médicos com mediana de idade de 33 anos, em sua maioria mulheres (71,1%) e metade residentes em pediatria. Durante a graduação, 43,1% relataram participação em cursos sobre imunodeficiências primárias, e 39,2% participação em conferências relacionadas. Durante o programa de residência, 25,9% relataram participação em cursos sobre imunodeficiências primárias, e 60,3% participação em conferências relacionadas. Entre os pediatras, 50% relataram participação em cursos sobre imunodeficiências primárias e 53,1% participação em conferências relacionadas. Apenas 39,8% dos médicos declararam conhecer os 10 sinais de alerta propostos pela Fundação Jeffrey Modell. Mais da metade dos médicos considerou a falta de acesso a exames laboratoriais o principal desafio no diagnóstico das imunodeficiências primárias. Conclusão Este estudo revelou conscientização limitada sobre imunodeficiências primárias entre os médicos do corpo clínico do Instituto Nacional de Salud del Niño. Embora a maioria dos médicos tenha suspeitado de imunodeficiências primárias em pacientes com histórico de infecções recorrentes e uso frequente de antibióticos, nem todos conheciam os 10 sinais de alerta propostos pela Fundação Jeffrey Modell e nem todos foram capazes de descrever os exames complementares solicitados nos casos suspeitos.

ABSTRACT Objective To investigate the level of awareness of primary immunodeficiency diseases among physicians working at Instituto Nacional de Salud del Niño. Methods Cross-sectional study including pediatric residents and pediatricians working at the Instituto Nacional de Salud del Niño during the study period (2017-2019). Physicians working at the immunology unit and surgery departments were excluded. Three aspects of awareness of primary immunodeficiency diseases were investigated: education, general knowledge, and diagnostic suspicion and actions taken in the face of suspicion. Results This sample comprised 83 physicians with a median age of 33 years. Most physicians were women (71.1%) and half were pediatric residents. During their undergraduate studies, 43.1% had taken primary immunodeficiency disease courses, and 39.2% had attended conferences on this topic. During their residency training, 25.9% had taken primary immunodeficiency disease courses, and 60.3% had participated in conferences on this topic. Among pediatricians, 50% had taken primary immunodeficiency disease courses, and 53.1% had attended conferences on this topic. Only 39.8% of physicians reported being familiar with the list of 10 warning signs developed by the Jeffrey Modell Foundation. More than half of physicians considered the lack of access to laboratory tests the major challenge in making diagnosis of primary immunodeficiency diseases. Conclusion This study revealed limited awareness of primary immunodeficiency diseases among physicians working at Instituto Nacional de Salud del Niño. Although most physicians suspected primary immunodeficiency diseases in patients with a history of recurrent infections and frequent use of antibiotics, not all of them were familiar with the list of 10 warning signs proposed by the Jeffrey Modell Foundation, nor were they able to describe ancillary tests requested in suspected cases.

ABSTRACT There is currently no vaccine available and no specific medication against Coronavirus 2019 disease (COVID-19). The treatment is mainly based on support measures. In this context, several potentially useful therapies have been approved for use in clinical trials, such as convalescent plasma transfusion (CPT). PubMed was searched for studies on convalescent plasma and COVID-19, SARS or MERS. Studies on clinical efficacy in diseases caused by other coronaviruses (SARS-CoV and MERS-CoV) showed clinical improvement, increase of neutralizing antibodies, decreased mortality and absence of adverse events during and after treatment. We found 13 studies on this type of treatment used in patients with severe and critical COVID-19. Despite limitations regarding methodology, number of patients and the protocols for the analysis of donors’ convalescent plasma, patients who received CPT showed clinical improvement, improvement of ventilatory patterns, resolution of lung injuries, decreased mortality, improvement of laboratory parameters, increase of neutralizing antibodies, decreased viral load and low frequency of adverse events.

RESUMEN Actualmente no existe vacuna disponible ni medicación específica contra la enfermedad por coronavirus 2019 (COVID-19). El tratamiento se basa fundamentalmente en medidas de soporte. En este contexto, se han aprobado múltiples terapias de potencial utilidad para su uso en ensayos clínicos, como la transfusión de plasma convaleciente (TPC). Se realizó una búsqueda en PubMed de estudios sobre plasma convaleciente y COVID-19, SARS o MERS. Los estudios sobre la eficacia clínica en enfermedades causadas por otros coronavirus (SARS-CoV y MERS-CoV) evidenciaron mejoría clínica, aumento de anticuerpos neutralizantes, disminución de la mortalidad y ausencia de eventos adversos durante y después del tratamiento. En el caso de la COVID-19, se encontraron 13 estudios en pacientes con la COVID-19 grave y crítica. Aunque existen limitaciones en la metodología, en el número de pacientes y en los protocolos para el análisis del plasma convaleciente de los donantes, los pacientes que recibieron TPC evidenciaron mejoría clínica, mejoría de patrones ventilatorios, resolución de lesiones pulmonares, disminución de mortalidad, mejoría de parámetros laboratoriales, aumento de anticuerpos neutralizantes, disminución de carga viral y baja frecuencia de eventos adversos.

Currently, there is no available vaccine or specific medication against Coronavirus Disease 2019 (COVID-19). The treatment is fundamentally based on supportive measures. In recent weeks, in various parts of the world, including our country, there have been flexibilities for the scientific community to conduct clinical trials with potentially useful therapies, such as the case of convalescent plasma transfusion (CPT) of patients with COVID-19. A MEDLINE search of studies on convalescent plasma and COVID-19, SARS or MERS was performed. Studies on the clinical efficacy of this treatment in diseases caused by other coronaviruses (SARS-CoV and MERS-CoV) showed clinical improvement, increased neutralizing antibodies, decreased mortality and the absence of adverse events during and after treatment. In the case of COVID-19, 6 studies were found of the use of this treatment in patients with severe COVID-19 (in mechanical ventilation and with acute respiratory distress syndrome). Although there are limitations in the methodology, number of patients and protocols for the analysis of convalescent plasma from donors, the patients who received CPT showed clinical improvement, improvement in ventilatory patterns, resolution of lung lesions, decreased mortality, improvement in laboratory parameters, increased neutralizing antibodies, decreased viral load and absence of adverse events. We also present a protocol for carrying out TPC and proposals for its implementation and use in our country.

En el caso del COVID-19, se encontraron 6 estudios del uso de este tratamiento en pacientes con COVID-19 severo (en ventilación mecánica y con síndrome de distrés respiratorio agudo). Aunque existen limitaciones en la metodología, número de pacientes y protocolos para el análisis del plasma convaleciente de los donantes, los pacientes que recibieron TPC evidenciaron mejoría clínica, mejoría de patrones ventilatorios, resolución de lesiones pulmonares, disminución de mortalidad, mejoría de parámetros laboratoriales, aumento de anticuerpos neutralizantes, disminución de carga viral y ausencia de eventos adversos. Presentamos además un protocolo de realización de TPC y propuestas para su implementación y uso en nuestro país.

ABSTRACT In order to determine the profile of sensitization to aeroallergens in pediatric patients with asthma and / or allergic rhinitis, a cross-sectional study was carried out in 411 patients using an allergy skin test. Age, sex, total IgE level and eosinophils were analyzed. The mean age was 8.1 ± 3.7 years and 60.6% were male. The average of the eosinophils and the level of total IgE was 450.1 ± 377.3 cells / mm3 and 861.7 ± 757.6 IU / mL, respectively. Mites were the most frequent sensitizing allergens (79.8%) and Dermatophagoides farinae (65.2%) was the most common. Polysensitization was present in 76.2% of patients. Sensitization was evident in the majority of patients with asthma and / or allergic rhinitis and was associated with age, age groups and total IgE level.

RESUMEN Con el objetivo de determinar el perfil de sensibilización a aeroalérgenos en pacientes pediátricos con asma y/o rinitis alérgica se realizó un estudio transversal en 411 pacientes usando una prueba cutánea de alergia. Se analizó la edad, sexo, nivel de IgE total y eosinófilos. La edad media fue de 8,1 ± 3,7 años y el 60,6% fueron varones. La media de los eosinófilos y el nivel de IgE total fue de 450,1 ± 377,3 células/mm3 y 861,7 ± 757,6 IU/mL, respectivamente. Los ácaros fueron los alérgenos sensibilizantes más frecuentes (79,8%) y el Dermatophagoides farinae (65,2%) fue el más común. La polisensibilización estuvo presente en el 76,2% de los pacientes. La sensibilización se evidenció en la mayoría de los pacientes con asma y/o rinitis alérgica y estuvo asociada con la edad, grupos etarios y nivel de IgE total.
