Rinitis alérgica en pediatría: recomendaciones para su diagnóstico y tratamiento / Allergic rhinitis in pediatrics: recommendations for diagnosis and treatment

La rinitis alérgica (RA) es una de las enfermedades crónicas más frecuentes de la infancia. Sin embargo, permanece subdiagnosticada y subtratada. Su prevalencia ha aumentado en los últimos años y varía del 2 % al 25 %. Los síntomas de la RA incluyen estornudos, prurito, rinorrea y congestión nasal. Un correcto diagnóstico y tratamiento de la RA y sus comorbilidades, tales como rinosinusitis con o sin poliposis nasal, conjuntivitis, otitis media, asma bronquial e infecciones del tracto respiratorio, son importantes para reducir el impacto negativo en la afectación de la calidad de vida del paciente y sus familiares, y los gastos sanitarios que ocasiona. La inmunoterapia alérgeno específica, en pacientes correctamente seleccionados, previene nuevas sensibilizaciones y reduce la hiperreactividad bronquial asociada a la RA. Considerando todos estos factores, el Comité Nacional de Alergia de la Sociedad Argentina de Pediatría propone recomendaciones basadas en la evidencia actual.

Allergic rhinitis (AR) is one of the most common chronic diseases in children. However, it remains underdiagnosed and undertreated. Its prevalence has increased in recent years and varies from 2 to 25 %. Symptoms include sneezing, itching, runny nose, and nasal congestion. A correct diagnosis and treatment of AR and its comorbidities such as rhinosinusitis with or without nasal polyposis, conjunctivitis, otitis media, bronchial asthma and respiratory tract infections, are important to reduce the negative impact on the quality of life of the patient and their relatives, and in medical costs. Specific allergen immunotherapy, in correctly selected patients, prevents new sensitizations and reduces bronchial hyperreactivity associated with AR. Taking into account all these reasons, the National Allergy Committee of the Sociedad Argentina de Pediatría proposes current evidence based recommendations

Evaluation of the efficacy of endoscopic posterior nasal neurectomy with pharyngeal neurectomy of allergic rhinitis combined with chronic rhinosinusitis with nasal polyps / 临床耳鼻咽喉头颈外科杂志

Objective:To investigate the effect of posterior nasal neurectomy（PNN） with pharyngeal neurectomy （PN） on chronic sinusitis with nasal polyps （CRSwNP）complicated with perennial allergic rhinitis （PAR）. Methods:83 patients with perennial allergic rhinitis combined with chronic group-wide sinusitis with nasal polyps who attended our hospital from July 2020 to July 2021 were selected. All patients underwent conventional functional endoscopic sinusitis surgery（FESS）+ nasal polypectomy. Patients were divided according to whether they underwent PNN+PN. 38 cases in the experimental group underwent FESS combined with PNN+PN; 44 cases in the control group underwent conventional FESS alone. All patients underwent the VAS, RQLQ, and MLK before treatment, and at 6 months and 1 year after surgery. Meanwhile, other relevant data were collected and the preoperative and postoperative follow-up data were collected and analyzed to assess the differences between the two groups. Results:The total postoperative follow-up period was 1 year. The recurrence rate of nasal polyps at 1 year postoperatively and the nasal congestion VAS score at 6 months postoperatively were not statistically significant in the two groups（P>0.05）. However, the patients in the experimental group had statistically significantly lower effusion and sneezing VAS scores, MLK endoscopy scores and RQLQ scores at 6 months and 1 year postoperatively, and nasal congestion VAS scores at 1 year postoperatively compared to the control group（P<0.05）. Conclusion:For patients with perennial AR complicated with CRSwNP, the combination of the PNN+PN in FESS can significantly improve the short-term curative effect, and PNN+PN is a safe and effective surgical treatment.

Bioinformatics analysis of nasal epithelial cell gene expression in seasonal and perennial allergic rhinitis / 中华耳鼻咽喉头颈外科杂志

Objective: Transcriptome sequencing and bioinformatics analysis were performed on the gene expression of nasal epithelial cells in patients with seasonal allergic rhinitis (AR) and perennial AR, so as to obtain the differences in the gene expression of nasal epithelial cells between seasonal AR and perennial AR. Methods: The human nasal epithelial cell line(HNEpC) was cultured in vitro, treated with 100 μg/ml mugwort or house dust mite (HDM) extracts for 24 hours. Total cell RNA was extracted, and quantitative real-time polymerase chain reaction (qPCR) was used to detect the expression of cytokines, including IL-6, IL-8, IL-33 and thymic stromal lymphopoietin (TSLP). From November 2019 to November 2020, 3 seasonal AR patients, 3 perennial AR patients, and 3 healthy controls who attended the Department of Otolaryngology Head and Neck Surgery, China-Japan Union Hospital of Jilin University were analyzed. The patients' primary nasal epithelial cells were cultured in vitro, treated with corresponding allergens for 24 hours. Total RNA was extracted for transcriptome sequencing, and the sequencing results were analyzed by bioinformatics. Results: The qPCR results showed that the cytokines IL-6, IL-8, IL-33 and TSLP of HNEpC treated with mugworts extracts and HDM extracts had the same trend of change. After the nasal epithelial cells from patients with seasonal AR and perennial AR were treated with corresponding allergens, there were differences in biological processes and signal pathways between those and control. Gene ontology (GO) enrichment analysis showed that the differentially expressed genes (DEG) in AR patients allergic to mugwort were mainly enriched in the oxidation-reduction process, the negative regulation of apoptosis process, and the cell adhesion; the DEG in AR patients allergic to HDM were mainly enriched in cell adhesion, the negative regulation of cell proliferation and the response to drug. Enrichment analysis of Kyoto Encyclopedia of Genes and Genomes (KEGG) signaling pathway showed that the DEG of AR patients allergic to mugwort were significantly enriched in arachidonic acid metabolism, p53 signaling pathway and transforming growth factor β (TGF-β) signaling pathway, while the DEG of AR patients allergic to HDM were mainly enriched in cells cycle, Fanconi anemia pathway and DNA replication. Gene Set Enrichment Analysis (GSEA) showed that the inflammatory response, TNF-α/NF-κB signaling pathway and IL-2/STAT5 signaling pathway were significantly up-regulated in AR patients allergic to mugwort, indicating the promotion of inflammatory response; and AR patients allergic to HDM had significant down-regulation of G2M, E2F, and MYC, indicating the inhibition of cell proliferation. The protein-protein interaction network showed that TNF and CDK1 were the most interacting proteins in mugwort and HDM allergic AR patients, respectively. Conclusion: Seasonal AR and perennial AR may affect the different biological processes and signal pathways of nasal epithelial cells, leading to differences in the occurrence and development of AR.

Rhinophototherapy, an alternative treatment of allergic rhinitis: Systematic review and meta-analysis / Rinofototerapia, uma alternativa para o tratamento de rinite alérgica: revisão sistemática e metanálise

Abstract Introduction: Allergic rhinitis is a chronic inflammatory disease of the nasal mucosa, mediated by immunoglobulin E, affecting 1 in 6 individuals. The treatment aims at attaining symptomatic control with minimal side effects, a requirement for new alternative therapies, including phototherapy, as it has an immunosuppressive and immunomodulatory effect. Objective: To identify the effectiveness of phototherapy in the treatment of allergic rhinitis through a meta-analysis. Methods: We searched Web of Science, Scielo, PubMed, SCOPUS, PEDro, and LILACS databases, using the terms: ''intranasal irradiation'', ''phototherapy'' and ''allergic rhinitis''. The R software Metafor package was used for the meta-analysis and the effect size was calculated for each symptom individually. Results: All symptoms decreased considerably after phototherapy: rhinorrhea (ES• = -1.35; p < 0.0001; I2 = 91.84%), sneezing (ES• = -1.24; p < 0.0001; I2 = 91.43%), nasal pruritus (ES• = -1.10; p < 0.0001; I2 = 91.43%); nasal obstruction (ES• = -1.11; p < 0.0001; I2 = 91.88%). The effects were more significant in perennial allergic rhinitis than in the seasonal type. Conclusion: Considering the effect size and the statistical significance attained in our study, rhinophototherapy showed to be an effective treatment for reducing the nasal symptom scores triggered by AR.

Conclusão: Considerando-se a magnitude do efeito e a significância estatística alcançadas em nosso estudo, a rinofototerapia demonstrou-se um tratamento eficaz para a redução dos escores dos sintomas nasais desencadeados pela rinite alérgica.

The efficacy and safety of ciclesonide for the treatment of perennial allergic rhinitis: a systematic review and meta-analysis / Eficácia e segurança da ciclesonida no tratamento da rinite alérgica perene: uma revisão sistemática e metanálise

Abstract Introduction: Allergic rhinitis is a chronic inflammatory disease which affects 1 out of 6 individuals. Perennial allergic rhinitis accounts for 40% of AR cases. Ciclesonide is one of the relatively new intranasal steroid for allergic rhinitis. Objective: The purpose of this study was to evaluate the efficacy and safety of ciclesonide in the treatment of perennial allergic rhinitis. Methods: We searched Pubmed, Scientific Citation Index, Embase, Clinical Trial Registries for randomized controlled trials and Cochrane Central Register of Controlled Trials to find out the randomized controlled Trial comparing ciclesonide with placebo for PAR. Results: Eight studies were included. In comparison with placebo groups, ciclesonide groups significantly decreased Reflective Total Nasal Symptom Score (MD = −0.56; 95% CI −0.72 to 0.39, p < 0.00001) with heterogeneity (p = 0.19, I2 = 24%), Instantaneous Total Nasal Symptom Score (MD = −0.57; 95% CI −0.75 to −0.39, p < 0.00001) with heterogeneity (p = 0.34, I2 = 11%). A significant effect for Reflective Nasal Symptom Score Subtotal (MD = −0.15; 95% CI −0.18 to −0.13, p < 0.00001) with heterogeneity (p = 0.12, I2 = 24%) was also demonstrated. Rhinoconjunctivitis quality of life questionnaire score (RQLQs) (MD = −0.27; 95% CI −0.39 to −0.15, p < 0.00001) with heterogeneity (p = 0.58, I 2 = 0%) in the treatment of ciclesonide was also significantly reduced. In addition, the difference in Treatment-Emergent Adverse Events between the two groups was not significant. Conclusion: Ciclesonide can improve perennial allergic rhinitis without increasing adverse events. Ciclesonide may be another valuable choice for perennial allergic rhinitis in the future.

Omalizumabe para o tratamento da asma alérgica grave / Omalizumab for the treatment of severe allergic asthma

Contexto: A asma é uma doença heterogênea, geralmente caracterizada por inflamação crônica das vias aéreas. A OMS estima que atualmente existam 235 milhões de pessoas com asma no mundo. Estima-se que, aproximadamente 5% dos pacientes asmáticos apresentem asma grave não é controlada com CI e LABA. O Protocolo Clínico e Diretrizes Terapêuticas (PCDT) da Asma do Ministério da Saúde classifica a asma em intermitente, persistente leve, persistente moderada e persistente grave. Para o tratamento da asma grave, o PCDT recomenda o uso de altas doses de CI associado a LABA; no caso da doença não ser controlada com esses medicamentos, pode-se aumentar a dose dos medicamentos e associar corticoide oral na dose mínima efetiva. Pergunta: O uso do omalizumabe é eficaz e seguro como terapia adicional ao tratamento padrão em pacientes diagnosticados com asma alérgica grave não controlada apesar do uso de média ou alta dose de CI associado a LABA (terapia padrão), quando comparado à terapia padrão isolada? Evidências científicas: Os dados da literatura científica demonstraram que o omalizumabe é um medicamento eficaz em reduzir a incidência de exacerbações, em curto e médio prazo, e em melhorar a qualidade de vida dos pacientes com asma grave não controlada com doses moderadas a altas de CI, associados ou não a LABA. Na maioria dos estudos controlados em adultos, o omalizumabe não mostrou reduções significativas na redução de hospitalizações e atendimentos em emergência ou consultas não programada, quando comparado ao controle. Num estudo que incluiu crianças e adolescentes, o omalizumabe reduziu as hospitalizações relacionadas à asma, mas no estudo que avaliou somente crianças, não houve diferenças entre o omalizumabe e placebo nesse desfecho. O efeito poupador de corticosteroide oral do omalizumabe foi demonstrado nos estudos observacionais. Nos pacientes com asma mais grave, que necessitam do uso de corticosteroide sistêmico e que seriam o grupo que mais se beneficiaria do uso do omalizumabe, as evidências científicas possuem limitações metodológicas. Poucos estudos avaliaram a eficácia do omalizumabe em crianças com asma grave, que provavelmente seriam os maiores beneficiados pela redução das doses de corticosteroides. Discussão: Apesar das evidências científicas demonstrarem a eficácia do omalizumabe na redução de exacerbações e na melhora da qualidade de vida dos pacientes com asma alérgica grave não controlada apesar do uso de média ou alta dose de CI associado a um LABA, as evidências científicas relacionadas aos benefícios do omalizumabe nos pacientes com doença mais grave, que necessitam de corticosteroides orais de forma contínua ou frequente, ainda são limitadas. Além disso, os dados econômicos apresentados possuem limitações importantes em sua construção, podendo determinar uma tecnologia potencialmente pouco custo-efetiva e de elevado impacto orçamentário. Decisão: Não incorporar o omalizumabe para o tratamento da asma alérgica grave não controlada com uso de média ou alta dose de corticoide inalatório associado a um beta 2-agonista de longa ação, no âmbito do Sistema Único de Saúde ­ SUS, dada pela Portaria SCTIE-MS nº 28 publicada no Diário Oficial da União (DOU) nº 130, de 08 de julho de 2016.

Near-Road Exposure and Impact of Air Pollution on Allergic Diseases in Elementary School Children: A Cross-Sectional Study

PURPOSE: The study aims to classify schools based on traffic pollutants and their complex sources, to assess the environment, to determine the state of allergic diseases among students using the International Study of Asthma and Allergies in children (ISAAC) questionnaire, and to assess their connection to air pollutants. MATERIALS AND METHODS: A total of seven schools were divided into three categories according to the characteristics of their surrounding environments: three schools in traffic-related zones, two schools in complex source zones I (urban), and two schools in complex source zones II (industrial complex). ISAAC questionnaires were administered and the 4404 completed questionnaires were analyzed. RESULTS: The frequency of asthma treatment during the past 12 months showed a significant increase (p<0.05) with exposure to NO2 [1.67, 95% confidence intervals (CIs) 1.03-2.71] in the complex source zones. The frequency of allergic rhinitis treatment during the past 12 months increased significantly with exposure to Black Carbon (1.60, 95% CIs 1.36-1.90) (p<0.001), SO2 (1.09, 95% CIs 1.01-1.17) (p<0.05), NO2 (1.18, 95% CIs 1.07-1.30) (p<0.01) for all subjects. CONCLUSION: In terms of supporting children's health, care, and prevention related to major spaces for children, such as school zones, spaces used in coming to and leaving school, playgrounds, and classrooms are essential to ensuring not only the safety of children from traffic accidents but also their protection from local traffic pollutants and various hazardous environmental factors.

Evaluation of the prevalence of stress and its phases in acute myocardial infarction in patients active in the labor market / Avaliação da prevalência do estresse e suas fases no infarto agudo do miocárdio em pacientes atuantes no mercado de trabalho

Introduction: Acute myocardial infarction is a social health problem of epidemiological relevance, with high levels of morbidity and mortality. Stress is one of the modifiable risk factors that triggers acute myocardial infarction. Stress is a result of a set of physiological reactions, which when exaggerated in intensity or duration can lead to imbalances in one's organism, resulting in vulnerability to diseases. Objective: To identify the presence of stress and its phases in hospitalized and active labor market patients with unstable myocardial infarction and observe its correlation with the life of this population with stress. Methods: The methodology used was a quantitative, descriptive and transversal research approach conducted with a total of 43 patients, who were still active in the labor market, presenting or not morbidities. Data collection occurred on the fourth day of their hospitalization and patients responded to Lipp's Stress Symptom Inventory for adults. Results: Thirty-one patients (72.1%) presented stress and twelve (27.8%) did not. In patients with stress, the identified phases were: alert - one patient (3.2%); resistance -twenty-two patients (71.0%); quasi-exhaustion - six patients (19.4%) and exhaustion - two patients (6.5%). All women researched presented stress. Conclusion: The results suggest a high level of stress, especially in the resistance phase, in the male infarcted population, hospitalized and active in the labor market. .

Introdução: O infarto agudo do miocárdio é um problema de saúde coletiva com altos índices de morbimortalidade com relevância epidemiológica. O estresse é um dos fatores de risco modificáveis desencadeantes do infarto agudo do miocárdio. O estresse é composto por um conjunto de reações fisiológicas que, se exageradas em intensidade ou duração, podem levar a um desequilíbrio do organismo, propiciando vulnerabilidade às doenças. Objetivo: Identificar a presença ou não do estresse e as fases do mesmo, em pacientes com infarto agudo do miocárdio, ativos no mercado de trabalho. Métodos: Pesquisa de abordagem quantitativa, descritiva e transversal que analisou 43 pacientes com diagnóstico de infarto agudo do miocárdio entre 21 e 65 anos, ativos no mercado de trabalho com ou sem comorbidades. A coleta de dados ocorreu no quarto dia de hospitalização; os pacientes responderam ao Inventário de Sintomas de Stress para adultos de Lipp. Resultados: A média de idade foi de 50,3 anos. A incidência de infarto agudo do miocárdio nos homens foi de 91% e nas mulheres de 9%. Em relação à escolaridade até o segundo grau entre homens e mulheres foi de 16% e com segundo grau completo ou mais, de 84%. Apresentaram estresse 31 pacientes (72,1%), não apresentaram estresse 12 (27,9%). Nos pacientes com estresse, as fases identificadas foram: alerta: 1 paciente (3,2%); resistência: 22 pacientes (71,0%); quase-exaustão: 6 pacientes (19,4%) e exaustão: 2 pacientes (6,5%). Todas as mulheres da pesquisa apresentaram estresse. Conclusão: Os resultados encontrados sugerem um elevado nível de estresse, principalmente na fase de resistência, na população de cardiopatas em infarto agudo do miocárdio ativos no mercado de trabalho. .

The comparison of efficacy between 3 and 4-year duration showed no significant difference in global clinical outcomes (all P > 0.05).</p><p><b>CONCLUSIONS</b>Patients receiving 2 year' SLIT achieve more clinical benefits than those who receiving 1-year duration. The higher efficacy of 3-year duration compared with 2-year duration is supported by a significant improvement in VAS. Besides, the comparison between 3 and 4-year duration shows no significant difference in global clinical outcomes. Therefore, 3 years' duration is optimal in this study.</p>

Effects of nasal symptoms on the psychological statuses of adults with moderate-to-severe persistent allergic rhinitis / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the psychological statuses of Chinese adults with moderate-to-severe persistent allergic rhinitis, and evaluate the effects of nasal symptoms on their psychological statuseses.@*METHOD@#The Symptom Checklist-90 (SCL-90) or self-reporting Inventory was employed to analyze the psychological statuses of 539 adults with moderate-to-severe persistent allergic rhinitis.@*RESULT@#The SCL-90 scores of the adults with moderate-to-severe persistent allergic rhinitis were statistically higher than those of non-allergic adults in terms of somatization, depression, anxiety and hostility. No statistical discrepancies existed in gender or age. The course of disease contributed to somatization and compulsion. The effects of nasal symptoms included two aspects: nasal obstruction had a conspicuous impact on somatization, compulsion, interpersonal sensitivity, depression, anxiety and psychosis, while nasal itching contributed to somatization, depression and anxiety.@*CONCLUSION@#The psychological statuses of adults with moderate-to-severe persistent allergic rhinitis is evidently worse than that of non-allergic adults. Symptoms such as nasal obstruction and itching had an obvious impact on outpatients' psychological statuses.

Efficacy of sublingual immunotherapy with Dermatophagoides farinae drops on patients with allergic rhinitis of different symptom severity / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To evaluate the efficacy of sublingual immunotherapy (SLIT) with Dermatophagoides farinae drops for allergic rhinitis (AR) of different symptom severity.@*METHOD@#This retrospective analysis to receive SLIT treatment of 143 cases of patients with allergic rhinitis, according to the severity of disease symptoms divid- ed into two groups, moderate group (62 patients) and severe group (81 patients). Before SLIT and after SLIT for half year, 1 year and 1. 5-2.0 years, the TNSS, TMS and sign scores of patients with allergic rhinitis were evaluated.@*RESULT@#The TNSS, TMS and sign scores had continuously improved significantly after SLIT for half year, 1 year and 1.5-2.0 years in two groups as compared with baseline (P 0.05). Half year after SLIT treatment, in two groups for sign scores, there were significant differences (Z = 3.32, P 0.05) and TMS (Z = 0.37, P > 0.05). 1 and 1.5-2.0 years after SLIT, there were no significant differences in two groups for TNSS, TMS and sign scores (P > 0.05).@*CONCLUSION@#SLIT with Dermatophagoides farinae drops for 1.5-2.0 years is effective in the patients with allergic rhinitis of different symptom severity. And equivalent efficacy could be achieved for different symptom severity.

Clinical diagnosis and treatment of allergic pharyngitis / 临床耳鼻咽喉头颈外科杂志

Although the concept of united airway disease has been widely accepted, most scholars emphasize only the effect of rhino-sinusitis while ignoring the pharyngeal factors to the lower airway, especially to the allergic pharyngitis (AP), which still lacks enough awareness. First of all, absence of unified diagnostic standard leads to the lack of epidemiological data, which, results in doctors' personal experience but no guideline in treatments. In addition, it is still not clear that the role of AP in the allergic airway diseases and its relationship with asthma. However, the number of patients with AP has been increasing obviously in daily clinic practice. Combined with the previous observation, this paper does a systematic review about the clinical problems of AP, expecting to give a hand to the clinical diagnosis and treatment of AP.

Prevalencia de alergias en niños entre 5 y 14 años con trastorno de déficitde atención e hiperactividad. Medellín, 2012 / Prevalence of allergies in children between 5 and 14 years of age with Attention Deficit and Hyperactivity Disorder. Medellin, 2012

Las enfermedades alérgicas y el trastorno por déficit de atención son entidades frecuentes enla niñez. Alguno autores han sugerido una asociación entre estas.Objetivos: Establecer la prevalencia de alergias en niños con déficit de atención y sus características clínicasy socio-demográficas en la consulta de neurología hecha por los autores.Materiales y Métodos: Estudio descriptivo, prospectivo, de corte transversal, con muestreo no aleatorio yselección de los casos de forma consecutiva. Se entrevistaron 113 niños que cumplían los criterios de inclusión,entre junio y diciembre de 2012. La información fue consignada en un formulario que contenía variables sociodemográficasy clínicas relacionadas con el déficit de atención y con los diferentes tipos de alergias.Resultados: Entre los pacientes entrevistados, la enfermedad alérgica mas frecuente fue la rinitis alérgica conel 37.2%, seguida por el asma, con 31.9%. Sin embargo, solo el asma presentó mayor prevalencia en pacientescon trastorno de déficit de atención e hiperactividad que en la población general. La dermatitis atópica se presentóen 8.8% y alergia alimentaria en 2.7%. En el análisis exploratorio, los niños con dermatitis atópica fueronlos únicos que presentaron una asociación significativa con insomnio (OR 4.23; IC 95%, 1.06-16; p=0.02).Conclusiones: La prevalencia de asma fue mayor en los pacientes estudiados con trastorno de déficit deatención e hiperactividad que la reportada en estudios poblacionales.

Desequilíbrio imunológico periférico mediado por células Th17/Treg em pacientes com rinite alérgica / Peripheral Th17/Treg cell-mediated immunity imbalance in allergic rhinitis patients

Introdução: A rinite alérgica (RA) é uma doença não infecciosa da mucosa nasal mediada por IgE após o contato com alérgenos. Objetivo: Investigar as células Th17 periféricas e CD4 + CD25 + Foxp3 + células T reguladoras (Treg) e a expressão sérica de citocinas em pacientes com RA. Métodos: De março a maio de 2012, foi coletado o sangue periférico de 14 pacientes com RA (grupo RA) e seis indivíduos saudáveis (grupo controle). A detecção das células Th17 e células Treg foi realizada através da citometria de fluxo e os níveis séricos de IL -17 e TGF- β1. Foram medidos por ELISA. Resultados: A percentagem de células Th17 no grupo RA foi bem maior do que no grupo controle (p < 0,01). A proporção de células Treg no grupo RA também foi drasticamente menor quando comparada ao grupo controle (p < 0,01). No grupo RA, o nível sérico de IL-17 foi significativamente maior do que no grupo controle (p < 0,01). Conclusão: O desequilíbrio de células Th17/Treg periféricas desempenha um papel importante na patogênese da RA. .

Introduction: Allergic rhinitis (AR) is an IgE-mediated non-infectious disease of the nasal mucosa following contact with allergens. Objective: To investigate the peripheral Th17 cells and CD4 + CD25 + Foxp3 + regulatory T (Treg) cells and the expression of cytokines in the serum of AR patients. Methods: The peripheral blood of 14 patients with AR (AR group) and six healthy subjects (control group) was collected from March to May of 2012. Flow cytometry was performed to detect the Th17 cells and Treg cells, and enzyme-linked immunosorbent assay (ELISA) to measure the serum levels of IL-17 and TGF-β1. Results: The proportion of Th17 cells in the AR group was markedly higher than that in the control group (p < 0.01). The proportion of Treg cells in the AR group was also dramatically reduced when compared with the control group (p < 0.01). In the AR group, serum IL-17 levels were markedly higher than those in the control group (p < 0.01). In the AR group, serum TGF-β1 levels were significantly lower than those in the control group (p < 0.01). Conclusion: The imbalance of peripheral Th17/Treg cells plays an important role in the pathogenesis of AR. .

Respiratory allergy to moth: the importance of sensitization to Bombyx mori in children with asthma and rhinitis / Alergia respiratória à mariposa: importância da sensibilização à Bombyx mori em crianças com asma e rinite

OBJECTIVE: this study aimed to prepare a silkworm moth (Bombyx mori) antigenic extract and to perform skin prick tests with this extract in patients with allergic respiratory diseases; to evaluate serum specific immunoglobulin E (IgE) to Bombyx mori using ImmunoCAP(r) system and to report the frequency of positivity between the two methods and with clinical data. METHODS: this was a cross-sectional study with 99 children and adolescents diagnosed with asthma and/or allergic rhinitis, who had skin reactivity to at least one of the six aeroallergens tested. Clinical data were evaluated: skin prick tests with Bombyx mori in-house extract, and total and specific IgE analysis using ImmunoCAP(r) were performed. RESULTS: the frequency of Bombyx mori specific IgE was found to be 52.5% and 60% using the skin prick test and ImmunoCAP(r), respectively. An association between a positive skin test for Bombyx mori and the presence of allergic rhinitis, atopic dermatitis, and urticaria was observed, but the same was not true for asthma or allergic conjunctivitis. There was no relation with the severity of asthma or rhinitis symptoms. CONCLUSIONS: a high frequency of sensitization to Bombyx mori was observed in a selected population of patients with respiratory allergic diseases in the city of Curitiba, state of Paraná, Brazil. The extract prepared from the wings of this moth species is effective in demonstrating this sensitivity. .

OBJETIVO: preparar extrato antigênico da mariposa do bicho-da-seda (Bombyx mori) e realizar testes cutâneos com esse extrato em pacientes com doenças respiratórias alérgicas, avaliar IgE sérica específica para Bombyx mori usando o sistema ImmunoCAP(r) e comparar a frequência de positividade entre os dois métodos e com dados clínicos. MÉTODOS: Estudo transversal com 99 crianças e adolescentes com diagnóstico de asma e/ou rinite alérgica, que apresentaram reação cutânea a pelo menos um dos seis aeroalérgenos testados. Os dados clínicos foram avaliados; testes cutâneos com extrato de Bombyx mori e análise de IgE total e específica por ImmunoCAP(r) foram realizados. RESULTADOS: a frequência de IgE específica para Bombyx mori foi de 52,5% e 60%, respectivamente, pelo teste cutâneo e ImmunoCAP(r). Foi observada uma associação entre o teste cutâneo positivo para Bombyx mori e a presença de rinite alérgica, dermatite atópica e urticária, mas o mesmo não ocorreu para a asma ou conjuntivite alérgica. Não houve relação com a gravidade dos sintomas de asma ou rinite. CONCLUSÕES: alta frequência de sensibilização à Bombyx mori foi encontrada em uma população selecionada de pacientes com doenças alérgicas respiratórias na cidade de Curitiba, estado do Paraná, Brasil. O extrato preparado a partir das asas dessa espécie de mariposa é eficaz em demonstrar essa sensibilidade. .
