Abstract Objective: Identify associated factors for recurrent wheezing (RW) in male and female infants. Methods: Cross-sectional multicentric study using the standardized questionnaire from the Estudio Internacional sobre Sibilancias en Lactantes (EISL). The questionnaire was applied to parents of 9345 infants aged 12-15 months at the time of immunization/routine visits. Results: One thousand two hundred and sixty-one (13.5%) males and nine hundred sixty-three (10.3%) females have had RW (≥3 episodes), respectively (p10 colds episodes (OR = 3.46; IC 95% 2.35-5.07), air pollution (OR = 1.33; IC 95% 1.12-1.59), molds at home (OR = 1.23; IC 95% 1.03-1.47), Afro-descendants (OR = 1.42; IC 95% 1.20-1.69), bronchopneumonia (OR = 1.41; IC; 1.11-1.78), severe episodes of wheezing in the first year (OR = 1.56; IC 95% 1.29-1.89), treatment with bronchodilators (OR = 1.60; IC 95% 1.22-2,1) and treatment with oral corticosteroids (OR = 1,23; IC 95% 0.99-1,52). Associated factors for RW for females were passive smoking (OR = 1.24; IC 95% 1.01-1,51), parents diagnosed with asthma (OR = 1.32; IC 95% 1,08-1,62), parents with allergic rhinitis (OR = 1.26; IC 95% 1.04-1.53), daycare attendance (OR = 1.48; IC 95% 1.17-1,88), colds in the first 6 months of life (OR = 2.19; IC 95% 1.69-2.82), personal diagnosis of asthma (OR = 1.84; IC 95% 1.39-2.44), emergency room visits (OR = 1.78; IC 95% 1.44-2.21), nighttime symptoms (OR = 2.89; IC 95% 2.34-3.53) and updated immunization (OR = 0.62; IC 95% 0.41-0.96). Conclusion: There are differences in associated factors for RW between genders. Identification of these differences could be useful to the approach and management of RW between boys and girls.

Abstract Objective Allergic sensitization is one of the key components for the development of allergies. Polysensitization seems to be related to the persistence and severity of allergic diseases. Furthermore, allergic sensitization has a predictive role in the development of allergies. The aim of this study was to characterize the pattern of sensitization of atopic patients treated at different pediatric allergy referral centers in Brazil. Methods A nation-wide transversal multicenter study collected data on patients attended in Brazil. Peripheral blood samples were collected to determine the serum levels of allergen-specific IgE. If allergen-specific IgE was higher than 0.1 kUA/L, the following specific components were quantified. Results A total of 470 individuals were enrolled in the study. Mite sensitization was the most frequent kind in all participants. A high frequency of sensitization to furry animals and grasses featured in the respiratory allergies. Regarding components, there was a predominance of sensitization to Der p 1 and Der p 2. It has been verified that having a food allergy, atopic dermatitis, or multimorbidity are risk factors for the development of more severe allergic disease. Conclusion Studies on the pattern of allergic sensitization to a specific population offer tools for the more effectual prevention, diagnosis, and treatment of allergic diseases. Sensitization to dust mites house was the most prevalent in the evaluated sample. High rates of sensitization to furry animals also stand out. Patients with food allergy, atopic dermatitis, or multimorbidity appear to be at greater risk for developing more severe allergic diseases.

RESUMO Objetivo O objetivo deste estudo foi avaliar a cinética diafragmática, a função respiratória e a dosagem sérica de leptina e citocinas inflamatórias (IL-6 e TNF-α) em três grupos clínicos: obeso, asmático e saudável. Métodos Estudo clínico-exploratório realizado com 73 jovens (12-24 anos, sendo 42,5% do sexo masculino) alocados em três grupos: obesidade (GO, n = 33), índice de massa corporal (IMC z-score) ≥ + 2 e asmáticos leves controlados (GA, n = 26), classificados pela GINA, e grupo controle saudável (GC, n = 14). Os participantes foram submetidos à ultrassonografia diafragmática, espirometria, pressão respiratória máxima, níveis séricos de leptina e níveis de IL-6 e TNF-α em hemocultura total. Resultados A espessura do diafragma foi maior no GO em comparação ao GA e GC (2,0 ± 0,4 vs 1,7 ± 0,5 e 1,6 ± 0,2, respectivamente, com p < 0,05). A ventilação voluntária máxima (VVM) foi significativamente menor no GO e GA em relação ao GC (82,8 ± 21,4 e 72,5 ± 21,2 vs 102,8 ± 27,3, respectivamente, com p < 0,05). O GO tem a maior taxa de leptina entre todos os grupos (com os outros dois grupos, p < 0,05). Os três grupos tinham níveis semelhantes de TNF-α e IL-6. Conclusão A hipertrofia muscular encontrada no diafragma de indivíduos obesos pode ser justificada pelo aumento do trabalho respiratório imposto pela condição crônica da doença. Esse aumento de espessura não ocorreu em asmáticos leves controlados. Os marcadores IL-6 e TNF-α não detectaram evidências de inflamação muscular, embora fosse esperado que a leptina estivesse alterada em indivíduos obesos. Pacientes obesos e asmáticos apresentaram menor resistência pulmonar do que os saudáveis.

ABSTRACT Objective The aim of this study was to assess the diaphragm kinetics, respiratory function, and serum dosage of leptin and inflammatory cytokines (IL-6 and TNF-α) in three clinical groups: obese, asthmatic, and healthy. Methods This is a clinical exploratory study performed on 73 youths (12-24 years of age, 42.5% male) allocated into three groups: obesity (OG, n=33), body mass index (BMIz-score) ≥ +2, asthmatic (AG, n=26) controlled mild asthmatics, classified by GINA, and Healthy Control Group (CG, n=14). The participants were subjected to diaphragmatic ultrasound, spirometry, maximal respiratory pressure, serum leptin levels, and IL-6 and TNF-α whole blood cell culture levels. Results Diaphragm thickness was higher in OG in comparison to AG and CG (2.0±0.4 vs 1.7±0.5 and 1.6±0.2, both with p<0.05). Maximal voluntary ventilation (MVV) was significantly lower in OG and AG in relation to the CG (82.8±21.4 and 72.5±21.2 vs 102.8±27.3, both with p<0.05). OG has the highest leptin rate among the groups (with the other two groups had p<0.05). All groups had similar TNF-α and IL-6 levels. Conclusion The muscular hypertrophy found in the diaphragm of the obese individuals can be justified by the increase in respiratory work imposed by the chronic condition of the disease. Such increase in thickness did not occur in controlled mild asthmatics. The IL-6 and TNF-α markers detected no evidence of muscle inflammation, even though leptin was expected to be altered in obese individuals. Both obese and asthmatic patients had lower pulmonary resistance than the healthy ones.

Resumo O SARS-CoV-2 é o responsável pela pandemia da COVID-19. O sistema imunológico é fator determinante no combate à infecção viral e, quando atua equilibrada e eficientemente, a doença é autolimitada e benigna. Uma parcela significativa da população, porém, apresenta resposta imune exacerbada. Os indivíduos diabéticos, hipertensos, obesos e com doenças cardiovasculares, infectados pelo vírus, apresentam maior chance de progredir para formas graves. Essas doenças estão relacionadas a processos inflamatórios crônicos e disfunção endotelial. Os receptores do tipo Toll estão presentes nas células de defesa e participam da imunopatologia de doenças cardiovasculares e metabólicas, levando à produção de citocinas pró-inflamatórias quando ativados. Devido à ação viral e à hiperativação do sistema imune, estados de hiperinflamação, hiperativação plaquetária, disfunção endotelial e hipercoagulabilidade são desenvolvidos, predispondo a tromboses venosas e arteriais. Discutiremos sobre a interação entre a COVID-19, a imunidade, o endotélio e a coagulação, como também sobre as possíveis causas de doenças cardiometabólicas impactarem negativamente na evolução da COVID-19.

Abstract SARS-CoV-2 is responsible for the COVID-19 pandemic. The immune system is a determinant factor in defense against viral infections. Thus, when it acts in a balanced and effective manner the disease is self-limited and benign. Nevertheless, in a significant proportion of the population, the immune response is exaggerated. When infected, patients with diabetes, hypertension, obesity, and cardiovascular disease are more likely to progress to severe forms. These diseases are related to chronic inflammation and endothelial dysfunction. Toll-like receptors are expressed on immune cells and play an important role in the physiopathology of cardiovascular and metabolic diseases. When activated, they can induce release of inflammatory cytokines. Hypercoagulability, hyperinflammation, platelet hyperresponsiveness, and endothelial dysfunction occur in immune system hyperactivity caused by viral activity, thereby increasing the risk of arterial and venous thrombosis. We discuss the interactions between COVID-19, immunity, the endothelium, and coagulation, as well as why cardiometabolic diseases have a negative impact on COVID-19 prognosis.

RESUMO Objetivo: Avaliar o nível de atividade física (AF) em asmáticos, comparando com não asmáticos, em estudo populacional. Métodos: Estudo transversal com adolescentes de 13 a 14 anos que participaram do estudo International Study of Asthma and Allergies in Childhood (ISAAC). Os indivíduos foram classificados em três grupos: indivíduos com asma ativa, indivíduos com diagnóstico de asma e assintomáticos respiratórios. Para avaliar o nível de AF, foi utilizado o Questionário Internacional de Atividade Física (IPAQ) versão curta. A análise consistiu na comparação de indivíduos com asma ativa, com diagnóstico de asma e assintomáticos, sendo o nível de significância considerado de 5%. Resultados: Participaram da pesquisa 1.591 adolescentes, 791 (49,7%) do sexo masculino. Apresentaram asma ativa 222 (14,0%) indivíduos e diagnóstico de asma 284 (17,8%). Foram fisicamente ativos 55,1% da população. Adolescentes com diagnóstico de asma foram mais ativos do que seus pares não asmáticos (64,4 versus 53,3%; p=0,001). Conclusões: Adolescentes com diagnóstico de asma apresentavam-se fisicamente mais ativos do que seus pares não asmáticos.

ABSTRACT Objective: To assess the level of physical activity in asthmatics in comparison with non-asthmatics in a population study. Methods: Cross-sectional study with 13 to 14-year-old adolescents who participated in the International Study of Asthma and Allergies in Childhood (ISAAC). The subjects were classified into three groups: individuals with active asthma, individuals diagnosed with asthma, and respiratory asymptomatic individuals. To evaluate the level of physical activity, the International Physical Activity Questionnaire (IPAQ-short version) was used. The analysis consisted of comparing individuals with active asthma, diagnosed as asthmatic and asymptomatic, with a significance level of 5%. Results: The participants were 1,591 adolescents, of which 791 (49.7%) were male. There were 222 (14.0%) individuals with active asthma and 284 (17.8%) asthma diagnoses; 55% of the population were physically active. Adolescents diagnosed with asthma were more active than their non-asthmatic peers (64.4 versus 53.3%; p=0.001). Conclusions: Adolescents diagnosed with asthma were more physically active than their non-asthmatic peers.

RESUMO Objetivo: Avaliar se houve associação entre a ocorrência de fratura após trauma físico e o uso de glicocorticoides nos 12 meses precedentes ao trauma, em crianças e adolescentes atendidos em uma emergência. Métodos: No período de abril a outubro de 2015 foi conduzido em uma emergência pediátrica um estudo tipo caso controle, em pacientes de 3 a 14 anos incompletos, vitimados por trauma físico, com e sem fratura. Os dados analisados foram obtidos pela consulta dos prontuários, pelo exame físico dos pacientes e por entrevista dos responsáveis, comparando-se uso de glicocorticoides nos últimos 12 meses, características demográficas, índice de massa corpórea, ingesta de leite, intensidade do trauma, prática de exercício físico e tabagismo passivo domiciliar nos dois grupos de pacientes. Resultados: Estudaram-se 104 pacientes com trauma físico, 50 com fratura e 54 sem fratura. O uso de glicocorticoides ocorreu em 15,4% dos pacientes estudados, sem diferença estatisticamente significante entre os dois grupos. A faixa etária de 10 a 14 anos incompletos, o trauma grave e a prática de exercício físico predominaram entre os pacientes com fratura. Conclusões: Este estudo não mostrou associação entre o uso prévio de glicocorticoides e a ocorrência de fraturas em crianças e adolescentes. A faixa etária de 10 a 14 anos incompletos, o trauma grave e a prática de exercício físico associaram-se com maior risco para fraturas.

ABSTRACT Objective: To assess the association between traumatic fractures and glucocorticoids taken 12 months prior to a trauma, in children and adolescents seen at an emergency room. Methods: A case-control study was conducted from April to October 2015, at a pediatric emergency hospital with patients aged 3- to 14 years-old, who had suffered physical trauma. Some of the patients had a fracture and some did not. The data analyzed were obtained from medical records, physical examination of the patients, and interview with the patients’ caregivers. Glucocorticoid use in the past 12 months, demographic variables, body mass index, milk intake, trauma intensity, physical activity and smoking in the household were compared between the two patient groups. Results: A total of 104 patients with physical trauma were studied - 50 had a fracture and 54 did not. Of all the patients, 15.4% had previously used glucocorticoids, and there were no statistically significant differences between the groups. The age range of 10- to 14 years-old, severe trauma and physical activity were more prevalent among patients with a bone fracture. Conclusions: This study did not find an association between previous glucocorticoid use and the occurrence of fractures in children and adolescents. The age range of 10- to 14 years-old, severe trauma, and physical activity were associated with an increased risk for fractures.

RESUMO Objetivo: identificar a acurácia do teste de contagem em uma única respiração para determinar a capacidade vital lenta em pacientes hospitalizados e avaliar sua repetibilidade entre o mesmo examinador. Métodos: estudo de diagnóstico em que a escolha das técnicas foi aleatoriamente atribuída. A área sob a curva (característica de operação do receptor) foi calculada a partir da capacidade vital lenta (20ml/kg) para avaliar as melhores características psicométricas do teste de contagem em uma única respiração para este ponto de corte. A repetibilidade observada pelo mesmo examinador foi avaliada usando o coeficiente de correlação intraclasse. Resultados: foram analisados (característica de operação do receptor/capacidade vital lenta=20ml/Kg), foi encontrado o valor de 21 em teste de contagem em uma única respiração com uma sensibilidade de 94,44% e especificidade de 76,62% (área abaixo da curva=0,93, p<0,005). O valor do coeficiente de correlação intraclasse para o teste de contagem foi 0,976 com p>0,005. Conclusão: o teste de contagem em uma única respiração foi uma técnica válida, repetitiva e pode ser uma importante opção de rastreamento para avaliação da função pulmonar na ausência de equipamentos específicos. Essa técnica abre perspectivas no que se refere à substituição da medição da capacidade vital lenta em hospitais que não possuem equipamento espirométrico ou em pacientes que apresentam uma doença contagiosa com risco de contaminação e propagação de doença de um paciente para outro.

ABSTRACT Purpose: to identify the accuracy of the single-breath counting test to determine slow vital capacity in hospitalized patients and to evaluate the repeatability of the same examiner. Methods: a diagnostic study and the choice of techniques were randomly assigned. The area under the curve (receiver operating characteristic) was calculated from the slow vital capacity (20ml/kg) to evaluate the best psychometric characteristics of single-breath counting Test for this cutoff point. Repeatability observed by the same examiner was assessed using the Intraclass Correlation Coefficient. Results: 516 patients hospitalized for various diseases were analyzed. In the curve analysis (receiver operating characteristic/slow vital capacity=20ml/Kg), the value of 21 in single-breath counting test with a sensitivity of 94.44% and specificity of 76.62% (area under the curve =0.93, p<0.005) was found. The intraclass correlation coefficient value for the single-breath counting test was 0.976 with p>0.005. Conclusion: the single-breath counting test was a valid and repetitive technique, and may be an important screening option for assessment of lung function in the absence of specific equipment. This technique opens perspectives to replace slow vital capacity measurement in hospitals, which lack spirometric equipment, or in patients who may have a contagious disease, which has a risk of contamination and spread of disease from one patient to another.

Abstract Introduction The guidelines on allergic rhinitis aim to update knowledge about the disease and care for affected patients. The initiative called "Allergic Rhinitis and its Impact on Asthma", initially published in 2001 and updated in 2008 and 2010, has been very successful in disseminating information and evidence, as well as providing a classification of severity and proposing a systemized treatment protocol. In order to include the participation of other medical professionals in the treatment of allergic rhinitis, it is important to develop algorithms that accurately indicate what should and can be done regionally. Objective To update the III Brazilian Consensus on Rhinitis - 2012, with the creation of an algorithm for allergic rhinitis management. Methods We invited 24 experts nominated by the Brazilian Association of Allergy and Immunology, Brazilian Association of Otorhinolaryngology and Head and Neck Surgery and Brazilian Society of Pediatrics to update the 2012 document. Results The update of the last Brazilian Consensus on Rhinitis incorporated and adapted the relevant information published in all "Allergic Rhinitis and its Impact on Asthma" Initiative documents to the Brazilian scenario, bringing new concepts such as local allergic rhinitis, new drugs and treatment evaluation methods. Conclusion A flowchart for allergic rhinitis treatment has been proposed.

Abstract: En | Text: En | PDF: En

Allergic asthma is a chronic, complex inflammatory disease of the airway. Despite extensive studies on the immunomodulation of T helper (Th) cell pathways (i.e., Th1 and Th2) in asthma, little is known about the effects of Th17 pathway modulation, particularly that involving peroxisome proliferator-activated receptors (PPARs). In response, two new thiazolidinedione derivatives-namely, LPSF-GQ-147 and LPSF-CR-35 were synthesized and evaluated for their immunomodulatory effects on Th17-related cytokines, including interferon γ (IFNγ), interleukin IL-6, IL-17, and IL-22 in the peripheral blood mononuclear cells of asthmatic children. Both compounds were nontoxic even at high concentrations (i.e., 100 µM). The LPSF-CR-35 compound significantly reduced the levels of IL-17A (p = .039) and IFNγ (p = .032) at 10 µM. For IL-22 and IL-6, significant reduction occurred at 100 µM (p = .039 and p = .02, respectively). Conversely, LPSF-GQ-147 did not significantly inhibit the production of the tested cytokines, the levels of all of which were more efficiently reduced by LPSF-CR-35 than methylprednisolone, the standard compound. Real-time polymerase chain reaction assay confirmed that LPSF-GQ-147 has significant PPARγ modulatory activity. Such data indicate that both LPSF-CR-35 and LPSF-GQ-147 are promising candidates as drugs for treating inflammation and asthma.

Resumo Objetivo: Verificar se lactentes com alergia à proteína do leite de vaca (APLV) apresentam níveis inadequados de vitamina D. Métodos: Estudo transversal, envolveu 120 crianças de até dois anos, um grupo com APLV e outro de comparação, captadas dos ambulatórios de Gastroenterologia Pediátrica, Alergologia Pediátrica e Puericultura de um hospital universitário, no Nordeste brasileiro. Foi aplicado um formulário e foram coletadas amostras sanguíneas para a análise da vitamina D, foram considerados inadequados os níveis < 30 ng/mL. Níveis de vitamina D foram expressos em média e desvio padrão e a frequência dos graus de suficiência e demais variáveis, em proporções. Resultados: Lactentes com APLV, quando comparados com os saudáveis, apresentaram uma menor média do nível da vitamina D (30,93 vs. 35,29 ng/mL) (p = 0,041) e maior frequência de deficiência (20,3% vs. 8,2) (p = 0,049). Maior frequência de níveis inadequados de vitamina D foi observada nas crianças com APLV que estavam em aleitamento materno exclusivo/predominante (p = 0,002). Independentemente do período de exposição solar, a frequência de um status inadequado de vitamina D foi semelhante entre os grupos (p = 0,972). Conclusões: Menores níveis de vitamina D foram observados em lactentes com APLV, especialmente naqueles em aleitamento materno exclusivo/predominante, que configura esse como um possível grupo de risco para essa deficiência.

Abstract Objective: To verify whether infants with cow's milk protein allergy have inadequate vitamin D levels. Methods: This cross-sectional study included 120 children aged 2 years or younger, one group with cow's milk protein allergy and a control group. The children were recruited at the pediatric gastroenterology, allergology, and pediatric outpatient clinics of a university hospital in the Northeast of Brazil. A questionnaire was administered to the caregiver and blood samples were collected for vitamin D quantification. Vitamin D levels <30 ng/mL were considered inadequate. Vitamin D level was expressed as mean and standard deviation, and the frequency of the degrees of sufficiency and other variables, as proportions. Results: Infants with cow's milk protein allergy had lower mean vitamin D levels (30.93 vs.35.29 ng/mL; p = 0.041) and higher deficiency frequency (20.3% vs.8.2; p = 0.049) than the healthy controls. Exclusively or predominantly breastfed infants with cow's milk protein allergy had higher frequency of inadequate vitamin D levels (p = 0.002). Regardless of sun exposure time, the groups had similar frequencies of inadequate vitamin D levels (p = 0.972). Conclusions: Lower vitamin D levels were found in infants with CMPA, especially those who were exclusively or predominantly breastfed, making these infants a possible risk group for vitamin D deficiency.

RESUMO Objetivo: Realizar tradução, adaptação e validação da Itch Severity Scale (ISS-Ped) para medir a gravidade de prurido em crianças e adolescentes com dermatite atópica. Métodos: Estudo metodológico de validação de instrumento, seguindo protocolos recomendados. Após a definição da versão traduzida, com participação de um profissional com experiência em validação de instrumentos, três professores de inglês, um professor de linguística e sete alergologistas, a Escala de Gravidade de Prurido (ISS-Ped) foi aplicada a 42 responsáveis por pacientes entre 2 e 18 anos de idade com dermatite atópica e a 42 responsáveis por indivíduos sem doença cutânea pruriginosa da mesma faixa etária. Resultados da escala foram comparados com a gravidade da dermatite atópica e o controle da doença, e entre os dois grupos. Resultados: A clareza das questões foi maior que 90%. A ISS-Ped mostrou forte correlação positiva com a gravidade da dermatite atópica (Pearson: 0,74; p<0,001) e boa correlação com o controle da doença (coeficiente de correlação ponto bisserial: 0,65; p<0,001), além de ótima consistência interna (α de Cronbach: 0,96) e adequada reprodutibilidade pela concordância do teste e reteste (coeficiente de correlação intraclasse variando de 0,89 a 0,99 com IC95% e p<0,001). Conclusões: A ISS-Ped apresentou-se viável, válida e confiável, sendo atingida equivalência satisfatória. A escala traduzida mostrou-se adequada para avaliar a gravidade do prurido em crianças e adolescentes com dermatite atópica, permitindo comparações na prática clínica e entre pesquisas de diferentes centros.

ABSTRACT Objective: To translate, adapt and validate the Itch Severity Scale to a Brazilian version (ISS-Ped) in order to measure the severity of pruritus in children and adolescents with atopic dermatitis. Methods: This is a methodological study of validation of an instrument following recommended protocols. The translated version was evaluated by a group of experts including one professional with experience in instrument validation, three English teachers, one linguistics teacher and seven allergists. After this, the scale was applied to 42 parents of children aged between 2 and 18 years old with atopic dermatitis, and 42 parents of children without pruritic diseases. Results were evaluated according to the severity of atopic dermatitis and disease control, and they were compared between groups with and without atopic dermatitis. Results: More than 90% of the questions were clear to the parents. The ISS-Ped showed a strong positive correlation with the severity of atopic dermatitis (Pearson: 0.74; p<0.001) and a good correlation with the control of dermatitis (point-biserial correlation coefficient: 0.65; p<0.001). The scale showed excellent internal consistency (Cronbach’s α: 0.96) and adequate test and retest agreement (95% confidence interval of intraclass correlation coefficient: 0.89-0.99; p<0.001). Conclusions: The ISS-Ped is a feasible, valid, reliable and satisfactorily equivalent. The translated scale was appropriate to assess the severity of itching in children and adolescents with eczema, allowing comparisons in the clinical practice and in the research setting.
