Recomendaciones ALAT para el uso de vacunas respiratorias. Guía de práctica clínica basada en evidencias / ALAT Recommendations for the Use of Respiratory VaccinesEvidence-Based Clinical Practice Guideline

Introducción: Las infecciones respiratorias son las enfermedades respiratorias con mayor mortalidad en el mundo. Las causadas por Streptococcus pneumoniae, virus de influenza, Bordetella pertussis, SARS-CoV-2 y el Virus Sincitial Respiratorio, cuentan hoy día con vacunas seguras y efectivas. Este documento representa una guía de práctica clínica (GPC) de la Asociación Latinoamericana de Tórax (ALAT), elaborada por iniciativa de los departamentos de enfermedades infecciosas y pediatría, con el objetivo de establecer recomendaciones sobre vacunas respiratorias, utilizando la evidencia disponible. Método: Se estableció un grupo de desarrollo de las guías conformado por cinco médicos responsables globales del proyecto, se crearon cinco subgrupos de trabajo, uno por cada vacuna, con expertos neumólogos de adulto, pediatras e infectólogos invitados, que generaron preguntas clínicas. Se trabajó con un grupo de expertos metodólogos que transformaron preguntas clínicas en preguntas PICO, seleccionándose nueve preguntas por método DELPHI. Luego, se utilizó el sistema GRADE (Grading of Recommendations Assessment, Development and Evaluation) para evaluar la evidencia disponible. Resultados: Se obtuvieron recomendaciones para población adulta y pediátrica de las vacunas de neumococo, influenza, tos ferina, COVID-19 y Virus Respiratorio Sincitial basadas en preguntas PICO. También se agregaron recomendaciones basadas en preguntas narrativas relacionadas al uso de vacunas respiratorias en población con enfermedades respiratorias crónicas como asma, EPOC y fibrosis pulmonar.

Introduction: Respiratory infections are the leading cause of respiratory disease-related mortality worldwide. Infections caused by Streptococcus pneumoniae, influenza virus, Bordetella pertussis, SARS-CoV-2 and Respiratory Syncytial Virus (RSV) now have safe and effective vaccines available.This document represents a Clinical Practice Guideline (CPG) by the Latin American Thoracic Association (ALAT), developed through the initiative of the departments of in-fectious diseases and pediatrics, with the goal of establishing recommendations on respiratory vaccines using the available evidence. Method: A guideline development group was established, composed of five lead physicians responsible for the overall project. Five working subgroups were created, one for each vaccine, involving invited experts in adult pulmonology, pediatrics, and infectious diseases, who formulated clinical questions. A group of expert methodologists then transformed these clinical questions into PICO questions, with nine questions selected using the DELPHI method. The GRADE (Grading of Recommendations Assessment, Development and Evaluation) system was then used to assess the available evidence. Results: Recommendations were obtained for the adult and pediatric populations for pneumococcal, influenza, pertussis, COVID-19 and Respiratory Syncytial Virus vaccines based on PICO questions. Additionally, recommendations based on narrative questions related to the use of respiratory vaccines in populations with chronic respiratory diseases such as asthma, COPD, and pulmonary fibrosis were included.

As vacinas contra a covid-19 em plataformas de vídeos curtos no Brasil: o caso do Kwai / Covid-19 vaccines on short video platforms in Brazil: the case of Kwai / Las vacunas contra la covid-19 en plataformas de videos cortos en Brasil: el caso del Kwai

Neste artigo, analisamos as temáticas, os posicionamentos, as formas expressivas, os atores legitimados e os recursos visuais e sonoros empregados na produção de 482 vídeos sobre vacinas, publicados de 2020 a 2022 na plataforma de vídeos curtos Kwai. A partir de análise temática e de análise de conteúdo, identificamos que os vídeos apresentaram, em sua maioria, posicionamento favorável ou neutro em relação às vacinas e que ressaltaram as experiências pessoais com a vacinação. Não obstante, utilizaram sobretudo um tom hu-morístico no tratamento do assunto, com potencial desinformativo quanto aos efeitos colaterais das vacinas. Concluímos assim que, por um lado, o Kwai tem sido utilizado para expressão de experiências positivas com a vacinação, que podem estimular a adesão aos imunizantes, mas, por outro, tem sido também espaço para a circulação de percepções negativas e temores que podem suscitar dúvidas quanto à segurança das vacinas.

In this article, we analyze the themes, positions, expressive forms, legitimized actors, and both visual and sound resources used in the production of 482 videos about vaccines, published from 2020 to 2022 on the short video platform Kwai. Based on thematic analysis and content analysis, we identified that the videos predominantly presented a favorable or neutral stance toward vaccines and that they highlighted personal experiences with immunization. However, they mainly used a humorous tone when dealing with the subject, thereby potentially disseminating misinformation regarding the adverse effects of vaccines. We thus conclude that, on the one hand, Kwai has been used to express positive experiences with vaccination, which can stimulate adherence to vaccinations, but, on the other hand, it has also been a space for the circulation of negative perceptions and fears that can raise doubts regarding the safety of vaccines.

En este artículo, analizamos los temas, posiciones, formas expresivas, actores legitimados y recursos visuales y sonoros utilizados en la producción de 482 videos sobre vacunas publicados de 2020 a 2022 en la plataforma de videos cortos Kwai. A partir del análisis temático y de contenido, identificamos que los videos presentaban, en su mayoría, una posición favorable o neutral con relación a las vacunas y que destacaban experiencias per-sonales con la vacunación. Sin embargo, al abordar el tema, utilizaron, principalmente, un tono humorístico, con potencial desinformativo sobre los efectos secundarios de las vacunas. De ese modo, concluimos que, por un lado, el Kwai tiene sido utilizado para expresar experiencias positivas con la vacunación que pueden estimular la adhesión a las vacunas, pero, por otro lado, también tiene sido un espacio para la circulación de percepciones negativas y miedos que pueden plantear dudas sobre la seguridad de las vacunas.

Este artigo se baseia em uma pesquisa que teve como objetivoapreender os sentidos atribuídos por brasileiros à primeira dose da imunização contra a covid-19. Trata-se de uma análise netnográfica. Os dados foram coletados em 2021 por meio da hashtag VACINAPARATODOS no Instagram. Os métodos utilizados para análise de dados foram: análise de similitude, com auxílio do software IRAMUTEQ e da análise do Discourse of the collective subject (discurso do sujeito coletivo), de Lefevre. Os resultados apontaram como ideias centrais: a emoção positiva e o sentimento de gratidão; a emoção negativa e o sentimento atribuído às vidas perdidas e ao negacionismo; o significado da primeira dose e o sentimento de esperança; a imunização e o exercício da cidadania: ato de consciência, responsabilidade e respeito. Os sentidos atrelados à oportunidade de acesso à vacina mostraram a dualidade de sentimentos que vão desde sensações positivas de reconhecimento e valorização até sentimentos negativos, de revolta e indignação, diante da hesitação vacinal e dos discursos antivacina.

This article bases on a research that aimed to understand the meanings attributed by Brazilians to the first dose of immunization against covid-19. A netnographic analysis was carried out. The data was collected in 2021 using the hashtag VACINAPARATODOS on Instagram. The methods used analyse the data were: similarity analysis, with the aid of the IRAMUTEQ software and of the analysis of Discourse of the collective subject, developed by Lefevre. The results pointed out the following central ideas: positive emotion and a feeling of gratitude; the negative emotion and a feeling attributed to lost lives and to denialism; the meaning of the first dose and the feeling of hope; the immunization and the exercise of citizenship: an act of conscience, responsibility and respect. The meanings linked to the opportunity to access the vaccine showed a duality of feelings ranging from positive feelings of recognition and appreciation to negative feelings of revolt and indignation, in the face of vaccine hesitancy and of the anti-vaccine discourses.

Neumonía bacteriana en niños en Ecuador: una mirada al impacto de las vacunas / Bacterial pneumonia in children in Ecuador: a look at the impact of vaccines

INTRODUCCIÓN: La neumonía adquirida en la comunidad es una de las enfermedades con mayor prevalencia en la comunidad pediátrica en nuestro país. De las diferentes etiologías que pueden causarlas, la neumonía ocasionada por Streptococcus pneumoniae puede ser prevenida con el uso de inmunización. Actualmente se disponen de tres tipos de vacunas antineumocócicas conjugadas autorizadas de uso pediátrico de forma sistemática. OBJETIVO: Identificar la prevalencia de neumonía bacteriana en niños bajo 5 años de edad, que requirieron hospitalización comparando la vacuna neumocócica recibida: 10 valente (PCV10) versus 13 valente (PCV13). PACIENTES Y MÉTODOS: Estudio de descriptivo, retrospectivo. Se incluyeron pacientes hospitalizados bajo 5 años de edad, con diagnóstico de neumonía bacteriana mediante codificación CIE10 en un hospital de tercer nivel de la ciudad de Quito-Ecuador, durante el año 2019. RESULTADOS: Se estudiaron 175 pacientes de los cuales 74 cumplieron con criterios clínicos de neumonía, de estos 46 recibieron PCV10 y 28 recibieron vacuna PCV13. DISCUSIÓN Y CONCLUSIONES: La prevalencia de neumonía bacteriana fue mayor en los pacientes inmunizados con PCV10 lo que sugiere una relación de menor probabilidad de neumonía con el uso de la vacuna PCV13.

BACKGROUND: Community-acquired pneumonia is one of the most prevalent diseases in the pediatric community in our country, of the different etiologies that can cause them, pneumonia caused by Streptococcus pneumoniae can be prevented with the use of immunization. Currently there are three types of authorized pneumococcal conjugate vaccines for pediatric use in a systematic way. AIM: To identify the prevalence of bacterial pneumonia in children under 5 years of age who required hospitalization by comparing the pneumococcal vaccine received: 10 valent (PCV10) versus 13 valent (PCV13). METHODS: Descriptive, retrospective study. Hospitalized patients under 5 years of age with a diagnosis of bacterial pneumonia by ICD10 coding in a third level hospital in the city of Quito - Ecuador during 2019 were included. Results: 175 patients were studied, of which 74 patients met clinical criteria for pneumonia, of these 46 received PCV10 and 28 received PCV13 vaccine. DISCUSSION AND CONCLUSIONS: The prevalence of bacterial pneumonia was higher in patients immunized with PCV10, suggesting a relationship of lower probability of pneumonia with the use of the PCV13 vaccine.

A rat model of rheumatoid arthritis: TDZD-8 is associated with the protection against the induction of the synovium knee joint IL-17A/GSK3beta/ROS/alpha-SMA axis of fibrosis / Un modelo de rata de artritis reumatoide: TDZD-8 está asociado con la protección contra la inducción del eje de fibrosis de la articulación sinovial de la rodilla IL-17A/GSK3ß/ROS/α-SMA

SUMMARY: Rheumatoid arthritis (RA) that affects the synovial knee joint causes swelling of the synovial membrane and tissue damage. Interleukin-17A (IL-17A) and the enzyme glycogen synthase kinase-3β (GSK3β) are involved in the pathogenesis of RA. The link between IL-17A, GSK3β, the oxidative stress, and the profibrogenic marker alpha-smooth muscle actin (α-SMA) with and without TDZD-8, GSK3β inhibitor has not been studied before. Consequently, active immunization of rats was performed to induce RA after three weeks using collagen type II (COII) injections. The treated group received daily injection of 1 mg/kg TDZD-8 for 21 days following the immunization protocol (COII+TDZD-8). Blood and synovium tissue samples were harvested at the end of the experiment. RA development was confirmed as corroborated by a substantial increase in blood levels of the highly specific autoantibody for RA, anti-citrullinated protein antibody as well as augmentation of reactive oxidative species (ROS) levels measured as lipid peroxidation. RA induction also increased synovium tissue levels of IL-17A and the profibrogenic marker, α-SMA. All these parameters seemed to be significantly (p<0.0001) ameliorated by TDZD-8. Additionally, a significant correlation between IL-17A, ROS, and α-SMA and biomarkers of RA was observed. Thus, knee joint synovium RA induction augmented IL-17A/GSK3β/ROS/α-SMA axis mediated arthritis in a rat model of RA, which was inhibited by TDZD-8.

La artritis reumatoide (AR) que afecta la articulación sinovial de la rodilla provoca inflamación de la membrana sinovial y daño tisular. La interleucina-17A (IL-17A) y la enzima glucógeno sintasa quinasa-3β (GSK3β) están involucradas en la patogenia de la AR. No se ha estudiadol vínculo entre IL-17A, GSK3β, el estrés oxidativo y el marcador profibrogénico actina de músculo liso alfa (α-SMA) con y sin inhibidor de TDZD-8, GSK3β. En consecuencia, se realizó una inmunización activa de ratas para inducir la AR después de tres semanas usando inyecciones de colágeno tipo II (COII). El grupo tratado recibió una inyección diaria de 1 µg/ kg de TDZD-8 durante 21 días siguiendo el protocolo de inmunización (COII+TDZD-8). Se recogieron muestras de sangre y tejido sinovial al final del experimento. El desarrollo de AR se confirmó como lo corroboró el aumento sustancial en los niveles sanguíneos del autoanticuerpo altamente específico para AR, el anticuerpo antiproteína citrulinada, así como el aumento de los niveles de especies oxidativas reactivas (ROS) medidos como peroxidación lipídica. La inducción de AR también aumentó los niveles de tejido sinovial de IL-17A y el marcador profibrogénico, α-SMA. Todos estos parámetros parecían mejorar significativamente (p<0,0001) con TDZD-8. Además, se observó una correlación significativa entre IL- 17A, ROS y α-SMA y biomarcadores de AR. Por lo tanto, la inducción de AR en la sinovial de la articulación de la rodilla aumentó la artritis mediada por el eje IL-17A/GSK3β/ROS/α-SMA en un modelo de rata de AR, que fue inhibida por TDZD-8.

Vacunación contra el SARS-CoV-2 en el personal de salud / Vaccination against SARS-CoV-2 in health personnel

Introducción: El virus Sars-cov2 es el causante de una enfermedad respiratoria, cuyo grado de severidad es variable, de formas sintomáticas leves a graves. Debido a que no se ha encontrado un tratamiento eficaz para hacerle frente a esta patología, se ha puesto el foco en la prevención mediante vacunas. Una población objetivo de la primera y segunda fase de vacunación a nivel país, fue el personal de salud, por lo que se realiza una encuesta para determinar qué tipo de patologías de base presentan, rango etario predominante, si presentaron algún efecto adverso, y cuántas dosis de inmunización recibieron. Objetivos: Describir el porcentaje de vacunación contra Sars-cov2 en el personal de salud, las enfermedades de base, efectos adversos presentados y describir los motivos por el que se evita la vacunación. Materiales y métodos: Se realizó un estudio descriptivo, observacional y transversal mediante una encuesta en línea (Google Forms). En el cuestionario se registraron las siguientes variables: sexo, edad, profesión dentro del área de salud, departamento de residencia, enfermedad de base, dosis principales y de refuerzo recibidas, efectos adversos presentados, necesidad de atención médica posterior y razones por las que no se han aplicado todas las dosis. Resultados: La mayoría de los encuestados fueron parte del personal médico (85.4%), en su mayoría se encontraban entre los 20-29 años y los 40-49 años. El 48.6% no presenta patologías de base. El 96.3% de la población recibió 2 dosis de la vacuna para Sars-cov2. El 46.3% recibió 2 dosis de refuerzo. Discusión: La predisposición a completar el esquema fue más baja de lo esperado, siendo menor de la mitad. La predisposición para recibir la vacuna contra el COVID-19, en la población general fue de 52,02%. Cabe recalcar que el éxito de un programa de vacunación depende de la proporción de la población que desee vacunarse. Conclusión: La vacunación es un medio de prevención por lo que su promoción es un paso importante para evitar la enfermedad grave. Es necesario realizar una buena educación a toda la población sobre la eficacia, las dosis necesarias para obtener inmunidad, los efectos adversos y los motivos que deben retrasar la colocación de las dosis, porque, como se menciona anteriormente, el éxito de un programa de vacunación depende de la proporción de la población que desee vacunarse.

Introduction: The Sars-cov2 virus is the cause of a respiratory disease, whose degree of severity is variable, from mild to severe symptomatic forms. Since no effective treatment has been found to deal with this pathology, the focus has been on prevention through vaccination. A target population for the first and second phase of vaccination at the country level was health personnel. So a online survey is performed to determine what type of underlying pathologies they present, the age range predominance, the side effects displayed and how many doses they received. Objectives: Describe the percentage of vaccination against Sars-cov2 in health personnel, the underlying diseases, adverse effects and, to describe the reasons why vaccination is avoided. Materials and methods: A descriptive, observational and cross-sectional study is carried out using an online survey (Google Forms). The following variables were recorded in the questionnaire: sex, age, profession within the health area, department of residence, underlying disease, main and booster doses received, adverse effects presented, need for subsequent medical attention and reasons why they did not have been applied all the doses. Results: Most of the respondents were part of the medical staff (85.4%), the majority were between 20-29 years and 40-49 years. The 48.6% do not present basic pathologies. The 96.3% of the population received 2 doses of the Sars-cov2 vaccine. 46.3% received 2 booster doses. Discussion: The predisposition to complete the scheme was lower than expected, being less than a half. The predisposition to receive the COVID-19 vaccine in the general population was 52.02%. It should be emphasized that the success of a vaccination program depends on the proportion of the population that wishes to be vaccinated. Conclusion: Vaccination is a way of prevention, so its promotion is an important step to avoid a serious disease. It is necessary to give a good education to the entire population about the efficacy, the necessary doses to obtain immunity, the adverse effects and the reasons that should delay the doses, because, as mentioned above, the success of a vaccination program depends on the proportion of the population that wants to be vaccinated.

Preparation of chitosan hydrochloride stabilized emulsion and its immunostimulatory effect / 生物工程学报

In order to increase the ability of oil-emulsion adjuvant to stimulate cellular immunity, chitosan hydrochloride with positive charge was selected to stabilize oil-in-water emulsion (CHE). In this paper, model antigen ovalbumin was selected to prepare vaccines with emulsion adjuvant, commercial adjuvant or no adjuvant. The emulsion was characterized by measuring the particle size, electric potential and antigen adsorption rate. BALB/c mice were immunized by intramuscular injection. Serum antibody levels, the numbers of IL-4-secreting cells in splenocytes, cytotoxic T lymphocyte (CTL) response, and the expression of central memory T cells were measured to evaluate the immunostimulatory effect. The results showed that chitosan hydrochloride can effectively stabilize the emulsion. The emulsion size is about 600 nm, and the antigen adsorption rate is more than 90%. After immunization, CHE could increase serum antibodies levels and increase IL-4 secretion. Expression of CTL surface activation molecules was also increased to stimulate CTL response further and to increase the CD44+CD62L+ in T cells proportion. CHE as adjuvant can stimulate humoral and cellular immunity more efficiently, and is expected to extend the duration of protection.

Preparation of Mycobacterium tuberculosis EsxV lipid nanoparticles subunit vaccine and its immunological characteristics / 生物工程学报

To prepare a lipid nanoparticle (LNP)-based subunit vaccine of Mycobacterium tuberculosis (Mtb) antigen EsxV and study its immunological characteristics, the LNP containing EsxV and c-di-AMP (EsxV: C: L) was prepared by thin film dispersion method, and its encapsulation rate, LNP morphology, particle size, surface charge and polyphase dispersion index were measured. BALB/c mice were immunized with EsxV: C: L by nasal drops. The levels of serum and mucosal antibodies, transcription and secretion of cytokines in lung and spleen, and the proportion of T cell subsets were detected after immunization. EsxV: C: L LNPs were obtained with uniform size and they were spherical and negatively charged. Compared with EsxV: C immunization, EsxV: C: L mucosal inoculation induced increased sIgA level in respiratory tract mucosa. Levels of IL-2 secreted from spleen and ratios of memory T cells and tissue-resident T cells in mice were also elevated. In conclusion, EsxV: C: L could induce stronger mucosal immunity and memory T cell immune responses, which may provide better protection against Mtb infection.

Evaluation of the humoral immunity in mice induced by foot-and-mouth disease virus-like particles-ZIF-8 complexes with different sizes / 生物工程学报

To further enhance the immune effect of the foot-and-mouth disease (FMD) virus-like particles (VLPs) vaccine, this study prepared FMDV VLPs-zeolitic imidazolate (framework-8, ZIF-8) complexes with different particle sizes. We used a biomimetic mineralization method with Zn2+ and 2-methylimidazole in different concentration ratios to investigate the effect of size on the immunization effect. The results showed that FMDV VLPs-ZIF-8 with three different sizes were successfully prepared, with an approximate size of 70 nm, 100 nm, and 1 000 nm, respectively. Cytotoxicity and animal toxicity tests showed that all three complexes exhibited excellent biological safety. Immunization tests in mice showed that all three complexes enhanced the titers of neutralizing and specific antibodies, and their immune effects improved as the size of the complexes decreased. This study showed that ZIF-8 encapsulation of FMDV VLPs significantly enhanced their immunogenic effect in a size-dependent manner.

Objective To produce rabbit polyclonal antibody against mouse testis expressed 38 (TEX38). Methods Full-length open reading frame sequence of TEX38 was amplified and inserted into the pET-30a-(+) vector to construct pET-30a-TEX38 prokaryotic plasmid. The recombinant plasmid was transformed into E.coli BL21, and expression was induced with isopropyl β-D-thiogalactopyranoside (IPTG). New Zealand white rabbits were immunized with TEX38 protein after purification and denaturation, then TEX38 polyclonal antibodies were collected from rabbit serum samples. ELISA was performed to detect the antibody titer. Western blot and immunofluorescence staining were performed to determine the specificity of TEX38 polyclonal antibodies. Results The pET-30a-TEX38 recombinant plasmid was constructed, and TEX38 prokaryotic protein was expressed and purified successfully. After immunization, the titer of TEX38 antibody reached 1:1 000 000. Western blot analysis and immunofluorescence staining showed that TEX38 was localized in the mouse spermatogenic cells and sperms with a good specificity. Conclusion The rabbit polyclonal antibody against mouse TEX38 is successfully produced, and the expression of TEX38 in mouse spermatogenic cells and sperms is validated.

A systematic review in health economics research on the expansion of human papilloma virus vaccination population to men / 中华预防医学杂志

Objective: To systematically collect and evaluate the health economics research of Human papilloma virus(HPV) vaccination population expansion to men, and to provide evidence for optimizing HPV vaccine immunization strategies. Methods: Health economics research studies on male HPV vaccination published in databases including PubMed, Web of Science, CNKI, and Wanfang Database from January 2010 to September 2022 were collected according to the systematic evaluation research design. The quality of the studies was assessed using the health economics evaluation reporting standards (2022 edition) (CHEERS 2022), with full score of 28. The results of the studies were reviewed and analyzed systematically. Results: A total of 21 studies complies with the criteria were included, all of which was foreign research. The average CHEERS score of the literatures was 25.71 points, range from 23 to 28 points. 85.71% (12/14) studies of the gender-neutral population showed that including male in HPV vaccination were more consistent with the cost effectiveness than female vaccination alone under certain conditions (target at adolescents of 10 to 15 years old or adults under 26 years old). 80.00% (4/5) of the studies target at ordinary men only were proved that male vaccination with HPV vaccine was in line with the cost-effectiveness. 2 studies targeting men who have sex with men (MSM) were both concluded that it met the cost-effectiveness. In addition, the results of 2 gender-neutral population studies and 1 study on men alone showed that extending HPV vaccination to men did not conform to cost effectiveness. The main reasons for the non-cost-effectiveness included the high price of vaccines and the age of vaccination. Conclusion: The quality of the health economics evaluation studies on expanding HPV vaccination to the male population is high. Vaccination targeting adolescents and young men as well as special groups (such as MSM) are likely to be cost-effective, and vaccinations for other groups are still need further evaluated. It is recommended that relevant research should be conducted to provide evidence for expanding the scope of HPV vaccination to men in China.

Establishing adult vaccination system to improve the quality of immunization services over the life course / 中华预防医学杂志

The scientific setting and standardized management of adult vaccination clinics will improve the accessibility of vaccination services, thereby increasing the vaccination rate. Currently, some provinces and cities in China have been exploring the construction of adult vaccination systems for many years, effectively improving the level of vaccination services, and forming some useful experiences and models. However, the construction of China's adult vaccination system is not yet perfect, and the service mode needs to be optimized. In the future, we should continue to improve the guarantee measures for adult vaccination, scientifically lay out the network, optimize the service mode, and improve the overall quality of immunization services over the life course.
