Respiratory allergy symptoms and cytokine profiles in the presence of anti-Ascaris antibody in Giardia lamblia-infected children.

Anti-Ascaris lumbricoides (Asc) IgE and IgG can immunomodulate the allergy; however, the influence of these isotypes has not been investigated in the giardiasis and allergy. Therefore, the frequency of respiratory allergy (RA) symptoms in Giardia lamblia-infected children, with or without anti-Asc IgE, IgG1, or IgG4 and Th1, Th2/Treg, and Th17 cytokine production, was evaluated. We performed a case-control study with children aged 2-10 years old selected by questionnaire and stool exams to form the groups: infected or uninfected with RA (G-RA, n = 55; nG-RA, n = 43); infected and uninfected without RA (G-nRA, n = 59; nG-nRA, n = 54). We performed blood leukocyte counts and in vitro culture. Cytokine levels in the supernatants (CBA), serum total IgE and anti-Asc IgE (ImmunoCAP), IgG1, IgG4, and total IgA (ELISA) were measured. Infection was not associated with allergy. Infected children showed increased levels of anti-Asc IgG1, IL-2, IFN-γ, IL-4, and IL-10. There was a lower frequency of allergy-related symptoms in anti-Asc IgG1-positive children than IgG1-negative (OR = 0.38; CI = 0.17-0.90, p = 0.027) and few eosinophils in G-RA than in G-nRA and more in G-nRA than in nG-nRA, whereas TNF-α levels were higher in the G-RA than in the nG-nRA group. For infected and positive anti-Asc IgG1, there was higher TNF-α and IL-10 production than G/-IgG1. IL-10 levels were lower in nG/ + IgG1 than in infected or non-infected, and both were negative for anti-Asc IgG1. Th1/Th2/IL-10 profiles were stimulated in the infected patients, and in those with circulating anti-Asc IgG1, the TNF-α production was strengthened with a lower risk for respiratory allergy symptoms.

Can physical exercise assist in controlling and reducing the severity of exercise-induced bronchospasm in children and adolescents? A systematic review.

OBJECTIVE: The aim of this study was to analyze whether physical exercise can contribute to improving the control and severity of exercise-induced bronchospasm (EIB) in children and adolescents. METHOD: This is a systematic review that used PubMed/Medline and Scopus databases as a search source, and using descriptors indexed to DeCS/Mesh. The articles were analyzed in three stages in the selection process. Methodological quality was assessed using the TESTEX scale. RESULT AND DISCUSSION: A total of 5867 articles were filtered in the initial search; however, only eight of these were included after the eligibility criteria. All presented improvements in cardiorespiratory fitness. Only two followed the international EIB diagnostic guidelines. Of these, only one described a reduction in FEV1 and considered that this improvement may influence the EIB response in children and adolescent athletes with a non-asthmatic sample. CONCLUSION: The studies analyzed in this review did not enable drawing a conclusion regarding the influence of physical exercise on EIB in asthmatics. The lack of clinical trials on EIB and physical exercise, as well as the difficulty in methodological standardization for EIB diagnosis evidence the lack of scientific knowledge in this area, serving as a stimulus for researchers to find more consolidated answers.

Reproducibility of eucapnic voluntary hyperpnoea for exercise-induced bronchoconstriction diagnosis in asthmatic children and adolescents.

BACKGROUND: Respiratory symptoms after exercise are frequently reported by asthmatic patients, and exercise-induced bronchoconstriction (EIB) is a frequent cause, which requires objective testing for diagnosis. Eucapnic voluntary hyperpnea (EVH) is recommended as a surrogate stimulus for this purpose. Its short-term reproducibility is not yet established in children and young adolescents with asthma. OBJECTIVE: To evaluate the short-term test-retest agreement and reproducibility of FEV1 changes after EVH in this population. METHODS: Asthmatic patients aged between 10 and 20 years underwent EVH for EIB diagnosis on two occasions 2-4 days apart at a specialized university clinic. FEV1 was measured at 5, 15, and 30 min after EVH with a target ventilation rate 21 times the baseline FEV1 . EIB was diagnosed as a decrease ≥10% in FEV1 from baseline. RESULTS: A total of 26 of 62 recruited individuals tested positive for EIB on both visits (positive group) and 17 on one visit only (divergent group), while 19 tested negative on both visits (negative group). The overall agreement was 72.5% (95%CI 61.6%, 83.6%), and Cohen's kappa coefficient was 0.452. Low bias (0.87%) and high intra-class correlation coefficient (0.854, 95%CI 0.758,0.912; p < .001) for FEV1 response between test days were found, but with wide limits of agreement (±20.72%). There were no differences in pre-challenge FEV1 or achieved ventilation rate between visits either between groups (p = .097 and p = .461) or within groups (p = .828 and p = .780). There were no safety issues. CONCLUSIONS: More than one EVH test should be performed in children and young adolescents with asthma to exclude EIB and minimize misdiagnosis and mistreatment.

Metotrexato em crianças e adolescentes com dermatite atópica: série de casos / Methotrexate in children and adolescents with atopic dermatitis: a case series

Introdução: A dermatite atópica é uma doença inflamatória crônica da pele que nas suas formas moderadas e graves afeta profundamente a qualidade de vida dos seus portadores e familiares. O metotrexato tem sido indicado off-label para casos graves e refratários em crianças e adolescentes, pois é uma opção terapêutica acessível e de baixo custo. Existe uma escassez de publicações envolvendo a medicação, sobretudo na faixa etária pediátrica. Objetivo e método: O presente estudo busca avaliar as características clínicas das crianças e adolescentes em uso atual ou prévio de metotrexato para tratamento de dermatite atópica moderada ou grave. Foram incluídos 10 pacientes, 60% do gênero masculino, mediana de idade no início do metotrexato de 14 anos (variando de 3 a 18 anos), e mediana do tempo de evolução da dermatite atópica de 14 anos (variando de 3 a 17 anos). Rinite alérgica e asma em 100% e 50% casos, respectivamente, e transtornos psíquicos em 60%. Resultados: Seis pacientes obtiveram melhora clínica com mediana de tempo de 9 meses (variando de 4 a 14 meses) e mediana do Scoring Atopic Dermatitis inicial de 50,5 (IIQ 13,8) e de 32,5 (IIQ 24,3) após 12 a 15 meses de tratamento. Efeitos adversos foram observados em 20% dos casos, e suspensão do metotrexato em apenas um paciente. Conclusão: Nesta série de casos com dez pacientes houve melhora clínica em seis, com poucos efeitos adversos, sendo uma alternativa terapêutica válida.

Introduction: Atopic dermatitis is a chronic inflammatory disease of the skin that in its moderate and severe forms profoundly affects the quality of life of patients and their families. Methotrexate has been used off-label for severe and refractory cases in children and adolescents, as it is an affordable and low-cost therapeutic option. There is a lack of publications addressing this medication, especially in the pediatric age group. Objective and method: The present study seeks to evaluate the clinical characteristics of children and adolescents in current or previous use of methotrexate for the treatment of moderate or severe atopic dermatitis. Ten patients were included, 60% were male, median age at the beginning of methotrexate use was 14 years (ranging from 3 to 18 years), and median time of course of atopic dermatitis was 14 years (ranging from 3 to 17 years). Allergic rhinitis and asthma were found in 100% and 50% of cases, respectively, and mental disorders in 60%. Results: Six patients achieved clinical improvement with a median time of 9 months (ranging from 4 to 14 months) and a median score in the initial Scoring Atopic Dermatitis of 50.5 (interquartile range, 13.8) and 32.5 (interquartile range, 24.3) after 12 to 15 months of treatment. Adverse effects were reported in 20% of cases, and methotrexate discontinuation in only one patient. Conclusion: In this case series of ten patients, methotrexate led to clinical improvement in six patients with few adverse effects, thus being a valid therapeutic alternative.

Use of honey associated with Ananas comosus (Bromelin) in the treatment of acute irritative cough / Uso do mel de abelha associado ao Ananas comosus (Bromelin) no tratamento da tosse irritativa aguda

Abstract Objective: To evaluate the immediate improvement rate of irritative cough in patients treated with the combination of Ananas comosus extract and honey (Bromelin®) compared with the use of honey alone (placebo group). Methods: Pragmatic, double-blind, randomized, parallel-group study with children aged between 2 and 15 years, with irritative cough for at least 24hours. The double-blind assessment of cough was through the number of observed coughing episodes and intensity score for a period of 10minutes of observation. The decrease of one point in the mean total score was considered as a therapeutic effect. Results: There was a reduction in coughing episodes in both groups, as well as in the cough score after 30minutes of drug or honey administration. The change in clinical score above two points, which could indicate marked improvement, occurred in five patients in the bromelin group and only in one in the placebo group, but without significant difference. There were no adverse events. Conclusions: The immediate improvement rate of irritative cough was similar in patients treated with combination of Ananas comosus extract and honey (Bromelin®) compared with the use of honey alone (placebo group). It is possible that honey has a therapeutic effect on mucus and cough characteristics (Clinical Trials: NCT01356693).

Resumo Objetivo: Avaliar a taxa de melhoria imediata da tosse irritativa em pacientes tratados com associação do extrato do Ananas comosus em mel de abelha (Bromelin®) e compará-la com a de uso do mel isolado (grupo placebo). Métodos: Estudo pragmático da vida real, duplo-cego, randômico, de grupos paralelos, em crianças, entre dois e 15 anos, com tosse irritativa havia pelo menos 24 horas. A avaliação da tosse foi duplo-cega foi feita por meio da avaliação do número de episódios observáveis e do escore de intensidade de tosse durante o período de 10 minutos de observação. A redução de um ponto na média do escore total foi considerada como efeito terapêutico. Resultados: Em ambos os grupos houve redução do número de episódios de tosse, assim como do escore de tosse após 30 minutos de administração do medicamento ou do mel. A mudança de escore clínico superior a dois, que poderia indicar melhoria acentuada, ocorreu em cinco pacientes do grupo com bromelina e em apenas um do placebo, mas sem diferença significante. Não ocorreram eventos adversos. Conclusões: A taxa de melhoria imediata da tosse irritativa foi similar entre pacientes tratados com associação do extrato do Ananas comosus em mel de abelha (Bromelin®) e com o uso do mel isolado (grupo placebo). É possível que haja um efeito terapêutico do mel nas características do muco e da tosse (Clinical Trials: NCT01356693).

Probiotics for the treatment of upper and lower respiratory-tract infections in children: systematic review based on randomized clinical trials / Probióticos no tratamento das infecções do trato respiratório superior e inferior nas crianças: revisão sistemática baseada em ensaios clínicos randomizados

ABSTRACT OBJECTIVES: Evaluate the effect of probiotics on the symptoms, duration of disease, and the occurrence of new episodes of upper and lower respiratory infections in healthy children. SOURCES: In order to identify eligible randomized controlled trials, two reviewers accessed four electronic databases [MEDLINE/PubMed, Scopus (Elsevier), Web of Science, and Cochrane (Cochrane VHL)], as well as ClinicalTrials.gov until January 2015. Descriptors were determined by using the Medical Subject Headings tool, following the same search protocol. SUMMARY OF THE FINDINGS: Studies showed to be heterogeneous regarding strains of probiotics, the mode of administration, the time of use, and outcomes. The present review identified 11 peer-reviewed, randomized clinical trials, which analyzed a total of 2417 children up to 10 incomplete years of age. In the analysis of the studies, reduction in new episodes of disease was a favorable outcome for the use of probiotics in the treatment of respiratory infections in children. It is noteworthy that most of these studies were conducted in developed countries, with basic sanitation, health care, and strict, well-established and well-organized guidelines on the use of probiotics. Adverse effects were rarely reported, demonstrating probiotics to be safe. CONCLUSIONS: Despite the encouraging results - reducing new episodes of respiratory infections - the authors emphasize the need for further research, especially in developing countries, where rates of respiratory infections in children are higher when compared to the high per capita-income countries identified in this review.

RESUMO OBJETIVOS: Avaliar o efeito do uso de probióticos na redução dos sintomas, da duração da doença e da ocorrência de novos episódios de infecções respiratórias superior e inferior em crianças saudáveis. FONTES DE DADOS: Com a finalidade de identificar ensaios clínicos randomizados elegíveis, dois revisores acessaram quatro bases de dados eletrônicas (Medline/PubMed, Scopus [Elsevier], Web of Science e Cochrane [The Cochrane Library]), além do ClinicalTrials.gov, até janeiro de 2015. Foram usados descritores, por meio da ferramenta Medical Subject Headings, e foi seguido um mesmo protocolo de busca. SÍNTESE DOS DADOS: Os estudos apresentaram grande heterogeneidade em relação às cepas de probióticos, à forma de administração, ao tempo de uso e aos desfechos. Identificamos 11 ensaios clínicos randomizados, revisados por pares, que analisaram 2.417 crianças até 10 anos incompletos. Na análise dos estudos, redução de novos episódios de doença foi o desfecho favorável ao uso dos probióticos no tratamento das infecções respiratórias na criança. Importante salientar que essas pesquisas foram feitas, em sua maioria, em países desenvolvidos, com condições de saneamento, de assistência à saúde e de regulamentação rigorosa ao uso de probióticos bem estabelecidos e organizados. Quanto aos efeitos adversos, pouco relatados, configuram os probióticos como seguros. CONCLUSÕES: Apesar do resultado encorajador - redução de novos episódios de infecções respiratórias - destacamos a necessidade de pesquisas futuras, principalmente em países em desenvolvimento, onde as taxas de infecções respiratórias na criança são maiores quando comparadas com as dos países de elevada renda per capita identificados nesta revisão.

Exercise-induced bronchoconstriction diagnosis in asthmatic children: comparison of treadmill running and eucapnic voluntary hyperventilation challenges.

BACKGROUND: Exercise-induced bronchoconstriction (EIB) occurs in up to 90% of young people with asthma and can be diagnosed using serial measurements of forced expiratory volume in 1 second (FEV1) after standardized exercise, usually treadmill running (TR). Eucapnic voluntary hyperventilation (EVH) is a guideline-recommended alternative challenge for EIB diagnosis. The 2 methods have not been compared for EIB diagnosis in this population. OBJECTIVE: To compare 2 methods of EIB diagnosis in children and adolescents with asthma. METHODS: Thirty-four children 8 to 18 years of age attending the allergy clinic of the Hospital das Clínicas (Recife, Brazil) from September through December 2013 were examined. All underwent a basal FEV1 determination followed by TR for 8 minutes or EVH for 6 minutes on consecutive days. The first challenge was chosen at random. Serial FEV1 determinations were obtained at 3, 5, 7, 10, 15, and 30 minutes after the challenge and the test result was considered positive if at least 2 consecutive FEV1 measurements decreased at least 10% below the basal value. RESULTS: Thirteen patients responded to the 2 challenges, 6 only after TR and 4 exclusively after EVH (agreement 71%, κ = 0.41). The 95% limits of agreement of FEV1 decreasing after the challenges were widely spread (mean 0.1%, limits 19.8% to -19.6%). CONCLUSION: The 2 tests cannot be used interchangeably and the reproducibility of the FEV1 response to the EVH challenge has to be properly evaluated to better understand its role in EIB diagnosis.

A workshop on asthma management programs and centers in Brazil: reviewing and explaining concepts.

OBJECTIVE: To report the results of a workshop regarding asthma management programs and centers (AMPCs) in Brazil, so that they can be used as a tool for the improvement and advancement of current and future AMPCs. METHODS: The workshop consisted of five presentations and the corresponding group discussions. The working groups discussed the following themes: implementation of asthma management strategies; human resources needed for AMPCs; financial resources needed for AMPCs; and operational maintenance of AMPCs. RESULTS: The workshop involved 39 participants, from all regions of the country, representing associations of asthma patients (n = 3), universities (n = 7), and AMPCs (n = 29). We found a direct relationship between a lack of planning and the failure of AMPCs. Based on the experiences reported during the workshop, the common assumptions about AMPCs in Brazil were the importance of raising awareness of managers; greater community participation; interdependence between primary care and specialized care; awareness of regionalization; and use of medications available in the public health system. CONCLUSIONS: Brazil already has a core of experience in the area of asthma management programs. The implementation of strategies for the management of chronic respiratory disease and their incorporation into health care system protocols would seem to be a natural progression. However, there is minimal experience in this area. Joint efforts by individuals with expertise in AMPCs could promote the implementation of asthma management strategies, thus speeding the creation of treatment networks, which might have a multiplier effect, precluding the need for isolated centers to start from zero.

OBJETIVO: Relatar os resultados de uma oficina de trabalho sobre programas e centros de atenção a asmáticos (PCAAs) no Brasil para que possam servir como instrumento para melhoria e avanço dos PCAAs existentes e criação de novos. MÉTODOS: A oficina de trabalho constituiu-se de cinco apresentações e discussões em grupos. Os grupos de trabalho discutiram os seguintes temas: implementação de uma linha de cuidado em asma; recursos humanos necessários para os PCAA; recursos necessários para financiar os PCAA; e manutenção do funcionamento dos PCAAs. RESULTADOS: A oficina envolveu 39 participantes de todas as regiões do país, representando associações de asmáticos (n = 3), centros universitários (n = 7) e PCAAs (n = 29). Evidenciou-se uma relação direta entre a ausência de planejamento e o insucesso dos PCAAs. Com base nas experiências brasileiras elencadas durante a oficina, as premissas comuns foram a importância da sensibilização do gestor, maior participação da comunidade, interdependência entre a atenção primária e a especializada, observação da regionalização e utilização dos medicamentos disponíveis no sistema público de saúde. CONCLUSÕES: O Brasil já tem um núcleo de experiências na área programática da asma. A implementação de uma linha de cuidado em doenças respiratórias crônicas e sua inclusão nas redes de saúde parecem ser o caminho natural. Porém, a experiência nessa área ainda é pequena. Agregar pessoas com experiência nos PCAAs na elaboração da linha de cuidado em asma encurtaria tempo na criação de redes de atenção com possível efeito multiplicador, evitando que se partisse do zero em cada local isolado.

Broncoespasmo induzido por exercício, atividade física e suas limitações em crianças e adolescentes: [revisão] / Exercise-induced bronchospasm, physical activity and its limitations in children and adolescents: [review]

O relato de sintomas respiratórios (chiado no peito, tosse ou dispneia)associados ao exercício físico percebidos pelas crianças ou seus pais,apesar de baixa sensibilidade e especificidade, tem sido frequentementeutilizado para o diagnóstico de broncoespasmo induzido por exercício(BIE) em detrimento da realização do teste formal de broncoprovocaçãocom exercício, o que pode resultar em número excessivo de pacientescom este diagnóstico. Paralelamente a isso, a preocupação com o poucotempo dedicado à realização de atividades físicas (AF) por criançase adolescentes asmáticos tem aumentado e o BIE tem sido apontadocomo um dos fatores limitantes para a prática de AF nesta população. Ospossíveis prejuízos advindos da redução das AF nessa faixa etária alertapara a necessidade de um cuidadoso diagnóstico do BIE e da corretaidentificação daqueles que realmente sofrem limitações pela doença,permitindo a instituição de medidas de controle e a prática segura de AF.Este artigo apresenta uma revisão narrativa da literatura sobre o BIE,fatores limitantes das atividades físicas em crianças e adolescentes asmáticos,o papel da história clínica no diagnóstico do BIE e a importânciade um diagnóstico confiável.

Respiratory symptoms complaints (wheezing, cough, dyspnea)associated with exercise, despite low sensitivity and specificity, hasoften been used as a reliable proxy for the diagnosis of exercise-inducedbronchospasm (EIB) instead of formal exercise bronchial provocationtest, which can result in over diagnosis. Parallel to this, concerns abouta reduction in time devoted to physical activities (PA) by asthmaticchildren and adolescents are increasing and the diagnosis of EIB has beensuggested as one of the limiting factors associated with lower PA levelsin this population. The possible physical, developmental e psychologicalconsequences of PA reduction in this age group warns about the needfor an accurate EIB diagnosis, allowing the institution of effective controlmeasures and encouragement of a safe PA practice. In this narrativeliterature review the authors discuss EIB, factors associated with PAlimitation in asthmatic children and adolescents, the role of dyspneacomplaints in relation to EIB diagnosis and the importance of a reliablediagnosis.
