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

Tratamiento de la rinitis alérgica en época de pandemia. Documento de consenso de sociedades médicas de América Latina y el Caribe / Treatment of allergic rhinitis in pandemic times. Consensus statement from medical societies of Latin America and the Caribbean

La rinitis alérgica ha ido en aumento en los países latinoamericanos, dando lugar a una creciente población de pacientes que necesitan tratamiento médico para esta afección respiratoria. Su similitud con la COVID-19 en cuanto a síntomas y la posibilidad de concurrencia con esta, hacen que la rinitis alérgica sea de particular interés para los sistemas de salud. Los países de América Latina y el Caribe han sido particularmente vulnerables por múltiples desafíos, entre estos, las altas tasas de pobreza, el acceso limitado a la atención médica y las limitaciones en la prestación de servicios básicos de salud, así como la ausencia de guías de tratamiento para la rinitis alérgica en situación de pandemia. Con el objetivo de proporcionar orientación esencial para los equipos multidisciplinarios de América Latina y el Caribe con respecto a la evaluación y el tratamiento de la rinitis alérgica durante la pandemia de COVID-19, se revisó literatura científica publicada sobre tratamiento de la rinitis alérgica y COVID-19, y se consideró la opinión de profesionales líderes de sociedades científicas de la región. Se analizaron las diferentes medidas para evitar contagios, y las diferentes estrategias de tratamiento con énfasis en la terapia intranasal y el tratamiento con vacunas contra la alergia. Se formuló una declaración de posicionamiento con la intención de mantener la continuidad del servicio médico en el contexto de una pandemia y minimizar la propagación, infección y complicación asociada con el coronavirus tipo 2 del síndrome respiratorio agudo severo en pacientes con seguimiento o comenzando tratamiento para la rinitis alérgica(AU)

Allergic rhinitis has been increasing in Latin American countries, leading to a growing population of patients who need medical treatment for this respiratory condition. Its similarity to COVID-19 in terms of symptoms and the possibility of concurrence with it, make allergic rhinitis of particular interest to health systems. The countries of Latin America and the Caribbean have been particularly vulnerable due to multiple challenges, including high poverty rates, limited access to medical care and limitations in the provision of basic health services, as well as the absence of guidelines of treatment for allergic rhinitis in a pandemic situation. With the aim of to provide essential management for multidisciplinary teams in Latin America and the Caribbean regarding the evaluation and treatment of allergic rhinitis during the COVID-19 pandemic, published scientific literature on the treatment of allergic rhinitis and COVID-19 was reviewed, and the opinion of leading professionals from scientific societies in the region was considered. The different measures to avoid infections and the different treatment strategies were analyzed, with an emphasis on intranasal therapy and treatment with allergy vaccines. A position statement was formulated with the intention of maintaining continuity of medical service in the context of a pandemic and minimizing the spread, infection and complication associated with severe acute respiratory syndrome coronavirus 2 in patients undergoing or starting treatment for allergic rhinitis(AU)

Effect of daily average temperature on the incidence of allergic rhinitis in Lanzhou / 中华耳鼻咽喉头颈外科杂志

Objective: To evaluate the effect of daily average temperature on the atteck of allergic rhinitis (AR) by analyzing the changes of the outpatient visits of AR in Lanzhou. Methods: The meteorological and air pollution data of Lanzhou City and the outpatient visits of AR in Departments of Otorhinolaryngology and head and neck surgery of The First Hospital of Lanzhou University, The Second Hospital of Lanzhou University and Gansu Provincial People's Hospital from 2013 to 2017 were collected to describe the meteorological factors, air pollutants and the outpatient visits of AR. The correlation among the three factors was then analyzed by Spearman rank correlation analysis. Using the distributed lag non-linear model, the relationship between daily average temperature and the number of daily outpatient visits of AR was studied and stratified by gender and age with the long-term trend, seasonal trend and other confounding factors controlled. Results: From 2013 to 2017, the outpatient visits of AR in the above three hospitals reached 20 008 person times. Daily average temperature in Lanzhou showed a non-linear correlation to the outpatient visits of AR, with a certain lag effect. When the daily average temperature was 22 ℃ and the cumulative lag was 21 days (lag 0-21 d), the relative risk (RR) peaked at 4.851 (95%CI: 3.986-5.904). The effect of relatively low temperature (2.3 ℃, P25), relatively high temperature (19.8 ℃, P75) and high temperature (25.5 ℃, P95) on lag 0-21 d were the highest, which were 1.761 (95%CI: 1.375-2.255), 4.299 (95%CI: 3.574-5.171) and 3.656 (95%CI: 3.046-4.389), respectively. According to the stratified analysis, low and relatively low temperature had more significant effect on the outpatient visits of AR among women and people aged 0-14 years. When lag was 0-21 days, the RR value of low temperature for female outpatient visits of AR was 1.433 (95%CI: 1.105-1.860); the RR value of relatively low temperature for female outpatient visits of AR was 1.879 (95%CI: 1.460-2.419); the RR value of low temperature for AR outpatient visits for people aged 0-14 years was 1.511 (95%CI: 0.999-2.287), the RR value of relatively low temperature for AR outpatient visits for people aged 0-14 years was 2.051 (95%CI: 1.383-3.042). Relatively high temperature, on the other hand, had a more significant effect on men and people aged 15-59 years. High temperature had a greater impact on the number of AR outpatients in men and people aged 0-14 years. Conclusions: Temperature may be an important influencing factor of AR onset in Lanzhou. At relatively high temperature (19.8 ℃), the risk of AR outpatient visits is significantly increased, and the cumulative lagged effects are observed. The sensitivity of AR patients to temperature is different in different genders and ages.

Epidemiological investigation of allergic rhinitis in central cities and countrysides of Inner Mongolia region / 中华耳鼻咽喉头颈外科杂志

Objective: To investigate the prevalence of allergic rhinitis (AR) in 3 central cities (Chifeng, Hohhot, Ordos) and the surrounding rural areas of Inner Mongolia region, and to look for possible risk factors related to the disease. Methods: From March to October of 2019, a multi-stage stratified random sampling epidemiological survey was conducted in Chifeng, Hohhot, Ordos and rural areas. The AR-related factors of the population were obtained in the form of face-to-face questionnaire survey, and the skin prick test (SPT) was taken for the participants. AR disease was diagnosed according to the "Guidelines for the Diagnosis and Treatment of Allergic Rhinitis (2015, Tianjin)". The daily airborne pollen situation in the three regions was monitored during the same period. SPSS 23.0 was used to analyze all survey results. Results: A total of 6 818 questionnaires were recovered, with 6 393 valid questionnaires. The self-reported prevalence of AR was 27.72% (1 772/6 393) and the confirmed prevalence of AR was 17.10% (1 093/6 393). The prevalence of perennial AR was 1.83% (117/6 393) while the prevalence of seasonal AR was 15.27% (976/6 393). The prevalence of AR diagnosed in females was higher than that in males (19.19% vs 15.34%, χ²=16.594, P<0.001) and the prevalence of females in the two age groups of 36-45 years and 46-55 years was significantly higher than that of males (18.17% vs 9.73%, 14.13% vs 7.25%, χ2 value was 23.848, 18.772, respectively, all P<0.001). The prevalence of confirmed diagnoses in ethnic minorities was higher than that of Han nationality, and the prevalence of confirmed diagnoses in urban areas was higher than that in rural areas (23.13% vs 16.20%, 27.27% vs 9.71%, χ2 value was 24.516, 336.024, respectively, all P<0.001). The main nasal symptoms of AR patients were sneezing (91.31%), nasal congestion (85.91%) and nasal itching (85.00%). The most common concomitant disease of AR was allergic conjunctivitis (73.99%). Asthma (OR=6.629), food allergy (OR=3.236), drug allergy (OR=1.786), application of antibiotics (OR=1.553), recent home decoration (OR=2.307), and smoking (OR=1.322) were the AR related risk factors. The highest proportion of SPT positive reactions was Artemisia annua (80.15%). The peak period of clinical symptoms of AR patients in Inner Mongolia region was July to September, which was consistent with the second peak period of airborne pollen monitoring. Conclusions: The prevalence of AR in central cities and the surrounding rural areas of Inner Mongolia region is 17.10%, and Artemisia species is the most important pollen allergen in this area. History of asthma, food allergy, drug allergy, antibiotic use, home decoration and smoking history are the related risk factors for AR.

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

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

Principales aeroalérgenos en rinoconjuntivitis alérgica en la ciudad de Temuco, Chile / Aeroallergens causing rhinoconjunctivitis

Background: Allergic rhinoconjunctivitis (ARC) has a prevalence of 30% in industrialized countries. For an accurate diagnosis and treatment, it is crucial to identify the causative aeroallergen. Aim: To evaluate aeroallergen sensitization in adults with ARC in the city of Temuco, Chile. Patients and Methods: A skin test against the main aeroallergens present in Temuco was carried out in patients aged 15 to 64 years with ARC diagnosed by medical examination and the Score For Allergic Rhinitis. Results: At least one aeroallergen sensitization was present in 234 (62.4%) out of 375 patients. Pollen-sensitized patients were positive mainly for Grasses (44.4%), Plantago (27.8%), Cynodon (26.1%), Sorrel (23.5%), Birch (14.9%), Nothofagus obliqua (13.3%) and Alder (11.1%). Dust mites were the most common non-pollinic sensitizing aeroallergens, including Dermatophagoides pteronyssinus (70.1%) and Dermatophagoides farinae (62.8%). Conclusions: According to our results, skin tests in the city of Temuco should include at least dust mites, pollens of Grasses, Plantago, Cynodon, Sorrel, Birch, Nothofagus obliqua and Alder, because these allergens account for 93% of ARC cases in this city.

Síntomas respiratorios asociados a alergia alimentaria / Respiratory symptoms associated with food allergy

In the last years the frequency of allergic diseases has risen in the world; however, their actual prevalence is unknown. In this context, current estimates of clinically relevant food allergy range from 1-3 % in children and adults in the general population. Respiratory symptoms associated with food allergy are described, but they are poorly evaluated by doctors probably because they are little known. This article is a review of the latest information described in the literature regarding this relationship.

La frecuencia de enfermedades alérgicas en el mundo ha aumentado en los últimos años, sin embargo, la prevalencia real de ellas no es conocida, dentro de este contexto la alergia alimentaria con manifestación clínica significativa se estima entre 1-3% en niños y adultos en la población general. Los síntomas respiratorios asociados a esta patología están descritos, pero son poco evaluados por los médicos probablemente debido a que son poco conocidos. Este artículo es una actualización de lo descrito en la literatura en relación a esta asociación.

Epidemiological trends of allergic diseases in adolescents / Tendência epidemiológica das prevalências de doenças alérgicas em adolescentes

ABSTRACT Objective: To assess the prevalences of asthma, allergic rhinitis, and allergic rhinoconjunctivitis in adolescents in the city of Belo Horizonte, Brazil, in 2012 by administering the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire, as well as to compare the observed prevalences with those found in studies performed 10 years earlier and employing the same methodology used here. Methods: This was a cross-sectional study conducted between May and December of 2012 and involving adolescents in the 13- to 14-year age bracket. Participants were randomly selected from among adolescents studying at public schools in Belo Horizonte and completed the ISAAC questionnaire. Proportions were calculated in order to assess the prevalences of asthma, allergic rhinitis, and allergic rhinoconjunctivitis in the sample as a whole, and the chi-square goodness-of-fit test was used in order to compare the prevalences observed in 2012 with those found in 2002. Results: The prevalences of symptoms of asthma, allergic rhinitis, and allergic rhinoconjunctivitis in 2012 were 19.8%, 35.3%, and 16.3%, respectively, being significantly higher than those found in 2002 (asthma, p = 0.006; allergic rhinitis, p < 0.01; and allergic rhinoconjunctivitis, p = 0.002). Conclusions: The prevalences of asthma, allergic rhinitis, and allergic rhinoconjunctivitis among adolescents in 2012 were found to be high, having increased in comparison with those found 10 years earlier, despite efforts in prevention, diagnosis, and treatment.

RESUMO Objetivo: Avaliar as prevalências de asma, rinite alérgica e rinoconjuntivite alérgica em adolescentes da cidade de Belo Horizonte (MG) através do questionário do International Study of Asthma and Allergies in Childhood no ano de 2012, bem como compará-las com aquelas obtidas em estudos realizados 10 anos antes empregando a mesma metodologia. Métodos: Estudo transversal realizado com estudantes de 13-14 anos de idade de escolas públicas localizadas no município, selecionados de forma aleatória simples, entre maio e dezembro de 2012, com a utilização do questionário. Foram realizados cálculos das diferenças de proporções para a análise das prevalências de asma, rinite alérgica e rinoconjuntivite alérgica na amostra geral, e o teste de qui-quadrado de adesão foi utilizado para a comparação das prevalências de 2012 e 2002. Resultados: As prevalências de sintomas de asma, rinite alérgica e rinoconjuntivite alérgica em 2012 foram de 19,8%, 35,3% e 16,3%, respectivamente. Houve aumentos significativos dessas prevalências em relação ao ano de 2002 (asma, p = 0,006; rinite alérgica, p < 0.01; e rinoconjuntivite alérgica, p = 0.002). Conclusões: Foram evidenciados elevadas taxas de asma, rinite alérgica e rinoconjuntivite alérgica entre os adolescentes estudados e aumentos dessas prevalências no intervalo de 10 anos, apesar dos esforços no âmbito da prevenção, diagnóstico e tratamento dessas doenças.

Prevalence of self-reported smoking experimentation in adolescents with asthma or allergic rhinitis / Prevalência do relato de experimentação de cigarro em adolescentes com asma e rinite alérgica

Objective: To determine the prevalence of smoking experimentation among adolescents with asthma or allergic rhinitis. Methods: This was a cross-sectional study involving adolescent students (13-14 years of age) in the city of Belo Horizonte, Brazil. The participants completed the Centers for Disease Control and Prevention and International Study of Asthma and Allergies in Childhood questionnaires, both of which have been validated for use in Brazil. We calculated the prevalence of smoking experimentation in the sample as a whole, among the students with asthma symptoms, and among the students with allergic rhinitis symptoms, as well as in subgroups according to gender and age at smoking experimentation. Results: The sample comprised 3,325 adolescent students. No statistically significant differences were found regarding gender or age. In the sample as a whole, the prevalence of smoking experimentation was 9.6%. The mean age for smoking experimentation for the first time was 11.1 years of age (range, 5-14 years). Among the adolescents with asthma symptoms and among those with allergic rhinitis symptoms, the prevalence of self-reported smoking experimentation was 13.5% and 10.6%, respectively. Conclusions: The proportion of adolescents with symptoms of asthma or allergic rhinitis who reported smoking experimentation is a cause for concern, because there is strong evidence that active smoking is a risk factor for the occurrence and increased severity of allergic diseases.

Objetivo: Avaliar a prevalência da experimentação de cigarro em adolescentes com asma ou de rinite alérgica. Métodos: Estudo transversal envolvendo escolares com 13-14 anos de idade na cidade de Belo Horizonte (MG). Os escolares preencheram os questionários do Centers for Disease Control and Prevention e do International Study of Asthma and Allergies in Childhood, ambos validados para uso no Brasil. Foram calculadas as prevalências de experimentação de cigarro na população geral estudada, naqueles com sintomas de asma ou de rinite alérgica e nos subgrupos em relação ao gênero e à idade da experimentação. Resultados: A amostra foi constituída por 3.325 adolescentes. Não houve diferenças estatisticamente significativas em relação ao gênero e a idade dos participantes. Na amostra geral, a prevalência da experimentação de cigarro foi de 9,6%. A média de idade da experimentação de cigarro pela primeira vez foi de 11,1 anos (variação, 5-14 anos). Nos adolescentes com sintomas de asma e de rinite alérgica, a prevalência autorrelatada de experimentação de cigarro foi de 13,5% e 10,6%, respectivamente. Conclusões: A proporção de adolescentes com asma ou rinite alérgica que relataram ter experimentado cigarro é preocupante, visto que há fortes evidências de que o tabagismo ativo é um fator de risco para a ocorrência e maior gravidade de doenças alérgicas.

Perfil de morbilidad otorrinolaringológica en niños con síndrome de Down / Ear, nose and throat disease profile in children with Down syndrome

Introducción: Los niños con síndrome de Down (SD) tienen mayor riesgo de desarrollar enfermedad otorrinolaringológica (ORL). Recomendaciones internacionales sugieren realizar tamizaje auditivo precoz y control periódico por especialista. Nuestro objetivo fue caracterizar la enfermedad ORL en niños con SD y proponer una recomendación adaptada a nuestra realidad. Pacientes y método: Estudio transversal, descriptivo, en niños de 6 meses a 15 años con SD. Los datos se obtuvieron por medio de entrevista a los padres y revisión de fichas clínicas. Resultados: Se analizaron 134 pacientes, con una edad promedio de 44,5 meses. El 78,8% de ellos presentaba enfermedad ORL, siendo la más frecuente la rinitis alérgica y otitis con efusión. El tamizaje auditivo estaba alterado en un 25% de ellos, el 50% de los mayores de 3 años con estudio de sueño tenían apnea obstructiva del sueño. Los niños de mayor edad tuvieron estadísticamente mayor frecuencia de enfermedad ORL. Conclusiones: Esta serie muestra una alta frecuencia de enfermedad ORL en niños con SD, lo que refuerza la necesidad de realizar tamizaje auditivo, sospechar e identificar las apneas obstructivas del sueño y derivación rutinaria al especialista para optimización de las condiciones auditivas que permitan el mejor desarrollo del niño con SD.

Introduction: The children with Down syndrome (DS) are at increased risk of ear-nose-throat (ENT) disorders. International recommendations suggest early hearing screening and periodic specialist evaluation. Our goal was to characterize ENT disorders in children with DS, and propose recommendations for the Chilean population. Patients and method: Cross-sectional, descriptive study, of children with DS, between 6 months and 15 years of age. The data was obtained by a health interview to the parents and review of medical records. Results: We analyzed 134 patients with an average age of 44.5 months. The 78.8% had ENT disorders, the most frequent ENT disorders was allergic rhinitis and otitis media with effusion. Hearing screening was abnormal in a quarter of the patients, 50% of children over 3 years of age had obstructive sleep apnea diagnosed by polysomnogram. Older children had a statistically higher frequency of ENT disorders. Conclusions: This series shows a high rate of ENT disorders in children with DS, which supports recommendations for hearing screening, high suspicion of obstructive sleep apnea and routine referral to an ENT specialist for prevention and aggressive therapy in order to reduce hearing loss and improve development of the child with DS.

Introducción. El efecto que tiene la lactancia materna y la alimentación complementaria sobre la prevalencia de las enfermedades alérgicas ha mostrado resultados inconsistentes. Objetivo. Evaluar el efecto de la lactancia materna y el momento de inicio de la alimentación complementaria en la prevalencia de las enfermedades alérgicas. Población y métodos. Estudio transversal analítico con base poblacional realizado en niños de 6 a 12 años de edad inscriptos en escuelas primarias, seleccionados mediante muestreo polietápico. Se aplicó a sus padres o tutores un cuestionario estructurado para identificar enfermedades alérgicas (asma, rinitis alérgica o dermatitis atópica), antecedente de lactancia materna prolongada y edad de inicio de la alimentación complementaria. La búsqueda de asociaciones entre variables se realizó mediante regresión logística. Resultados. Se incluyeron 740 niños. La frecuencia de lactancia e" 6 meses fue 73,4% y de alimentación complementaria con d" 4 meses fue 31,9%. La lactancia materna prolongada no tuvo efecto sobre la prevalencia de las enfermedades alérgicas. Se observó un efecto protector en la frecuencia de la dermatitis atópica cuando el inicio de la alimentación complementaria era tardío, OR ajustado= 0,36; IC95%: 0,1-0,8 (p 0,019). Conclusiones. El efecto protector de la lactancia materna sobre la prevalencia de las enfermedades alérgicas no pudo ser comprobado. La prevalencia de dermatitis atópica es menor con un comienzo tardío de la alimentación complementaria.

Introduction. The effect that breastfeeding and complementary feeding practices have on the prevalence of allergic diseases has shown inconsistent results. Objective. To assess the effect of breastfeeding and the initiation of complementary feeding on the prevalence of allergic disease. Population and Methods. Analytical, crosssectional population-based study conducted in 6-12 year old children attending primary school and selected through a multistage sampling technique. A structured questionnaire was administered to parents or tutors to identify allergic diseases (asthma, allergic rhinitis, or atopic dermatitis), a history of prolonged breastfeeding and age at initiation of complementary feeding. A logistic regression analysis was used to establish associations among variables. Results. A total of 740 children were included. The frequency of breastfeeding for >6 months was 73.4%, and of complementary feeding at <4 months old was 31.9%. Prolonged breastfeeding showed no effect on the prevalence of allergic diseases. A protective effect was observed on the frequency of atopic dermatitis when complementary feeding was initiated late, adjusted OR= 0.36, 95% confidence interval (CI): 0.1-0.8 (p 0.019). Conclusions. The protective effect ofbreastfeeding against the prevalence of allergic diseases has not been demonstrated. There is a reduction in the prevalence of atopic dermatitis when complementary feeding is started late.

Temporal trends in the prevalence of asthma and rhinoconjunctivitis in adolescents / Evolução temporal na prevalência de asma e rinoconjuntivite em adolescentes

ABSTRACT OBJECTIVE To analyze the temporal trend of asthma and rhinoconjunctivitis prevalences as well as their symptoms in adolescents. METHODS Two cross-sectional studies were conducted using the same methodology and questionnaire as was used for adolescents aged 12 to 14 years in the Brazilian city of Florianopolis, SC, Southern Brazil. Based on the international protocol of the International Study of Asthma and Allergies in Childhood (ISAAC) study, adolescents were evaluated in 2001 and 3,150 in 2012. The schools included in this study were the same as in the 2001 study. These schools were randomly selected after stratification by network (public and private) and geographic location. The total average percentage variation was estimated for the prevalence of asthma and rhinoconjunctivitis and their symptoms. RESULTS The prevalence of reported asthma was 10.9% in 2001 and 14.8% in 2012, with an average variation of 2.8% in the period. The highest average variation in the period was observed among female adolescents (4.1%). In parallel a significant increase occurred in reported physician-diagnosed asthma, 7.3% in 2001 and 11,1% in 2012, with an annual variation of 4.5%. The largest increases in reported physician-diagnosed asthma were seen in female (5.9%) and male (4.5%) public school pupils. In addition, a significant increase in reported rhinoconjunctivitis occurred, with the average variation in the period being 5.2%. Reports of severe asthma symptoms remained unchanged during the period, while the annual variation for reported current wheezing (-1.3%) and wheezing during exercise (-1.2%) decreased. CONCLUSIONS The results showed a significant increase in the annual average variation for asthma and rhinoconjunctivitis prevalence during the 2001 to 2012 period.

A 9-year Trend in the Prevalence of Allergic Disease Based on National Health Insurance Data / 예방의학회지

OBJECTIVES: To investigate trends in the prevalence of allergic disease over a 9-year period. METHODS: Using National Health Insurance Service (NHIS) data, the annual number of patients with allergic disease was obtained for each regional subdivisions (small cities, counties, and districts) from 2003 to 2011. Annual populations for each sub-region were obtained and used to calculate the standardized prevalence. To compare prevalence within the study period, data was standardized spatially and temporally. For standardization, demographic data was used to obtain the registered population and demographic structure for 2010, which was used to perform direct standardization of previous years. In addition, a geographic information system (GIS) was used to visualize prevalence for individual sub-regions, and allergic diseases were categorized into five groups according to prevalence. RESULTS: The nationwide outpatient prevalence of allergic rhinitis increased approximately 2.3-fold, from 1.27% in 2003 to 2.97% in 2013, while inpatient prevalence also increased approximately 2.4-fold,. The outpatient prevalence of asthma increased 1.2-fold, and inpatient prevalence increased 1.3-fold. The outpatient prevalence of atopic dermatitis decreased approximately 12%, and inpatient prevalence decreased 5%. CONCLUSIONS: There was a large difference between prevalence estimated from actual treatment data and prevalence based on patients' self-reported data, particularly for allergic rhinitis. Prevalence must continually be calculated and trends should be analyzed for the efficient management of allergic diseases. To this end, prevalence studies using NHIS claims data may be useful.

Rinitis alérgica, prevalencia y factores de riesgo en adolescentes cubanos / Allergic rhinitis, prevalence and risk factors among Cuban adolescents

Introducción: la rinitis alérgica es una afección común que afecta el 10 por ciento-30 por ciento de la población mundial. Se desconoce la prevalencia y los factores de riesgo a escala nacional. Objetivo: estimar la prevalencia de los factores de riesgo de rinitis alérgica en adolescentes de 13 y 14 años. Métodos: estudio descriptivo transversal. Diseño muestral complejo. Encuestados 5 799 escolares (áreas urbanas y rurales del país). Se aplicó el cuestionario Estudio Internacional de Asma y Alergias en la Infancia. Se añadieron variables para evaluar exposición a posibles factores de riesgo. Se calcularon razones de disparidad (IC 95 por ciento) y se trabajaron modelos de regresión logística. Se realizó revisión bibliográfica actualizada, periodo 2008-2013, para contrastar los datos obtenidos en la encuesta nacional con los referidos en la literatura internacional. Resultados: participación de estudiantes: 86 por ciento. Prevalencia de rinitis en los últimos 12 meses: 38 por ciento; rinoconjuntivitis, 29 por ciento. Se asoció significativamente a sexo femenino: 1,68 (1,66-1,70), historia familiar de asma-alergia: 2,02 (1,99-2,05), convivencia con fumadores: 1,09 (1,07-1,11), hacinamiento en vivienda: 1,14 (1,12-1,16), ventilación inadecuada: 1,15 (1,13-1,16), tenencia de mascotas: perro, 1,25 (1,23-1,27), ubicación de vivienda y escuela en avenidas principales: 1,27 (1,24-1,29) y 1,10 (1,08-1,12) respectivamente y solucionar problemas en el núcleo familiar peleando o conversando: 1,31 (1,28-1,33). Conclusiones: la rinitis alérgica es una condición frecuente y subdiagnosticada en los adolescentes cubanos. La mayoría de los factores de riesgo identificados son modificables. La vigencia de los hallazgos encontrados descansa en que la dinámica de las enfermedades crónicas no se observan variaciones a corto plazo. Se construyó una línea de base a escala nacional, que permitirá la evaluación de la efectividad de acciones preventivas y de control(AU)

Introduction: Allergic rhinitis is a common condition affecting 10 percent-30 percent of the world population. The prevalence and risk factors for allergic rhinitis on a national scale are not known. Objective: Estimate the prevalence and risk factors for allergic rhinitis among 13- and 14-year-old adolescents. Methods: Descriptive cross-sectional study. Complex sampling design. 5 799 school children from urban and rural areas were surveyed using the questionnaire International Study of Asthma and Allergies in Childhood. Variables were added to include exposure to potential risk factors. Odds ratios (CI 95 percent) were estimated and logistic regression models were developed. An updated bibliographic review was conducted of the 2008-2013 period to contrast the data obtained by the national survey with those in the international literature. Results: Participation of students: 86 percent. Prevalence of rhinitis in the last 12 months: 38 percent; rhinoconjunctivitis: 29 percent. The condition was significantly associated with the following variables: female sex: 1,68 (1,66-1,70); a family history of asthma-allergy: 2,02 (1,99-2,05); living with smokers: 1,09 (1,07-1,11); overcrowded household: 1,14 (1,12-1,16); inadequate ventilation: 1,15 (1,13-1,16); pet ownership: dog: 1,25 (1,23-1,27); location of the home and school on main avenues: 1,27 (1,24-1,29) and 1,10 (1,08-1,12), respectively; and dealing with family problems by talking or fighting: 1,31 (1,28-1,33). Conclusions: Allergic rhinitis is a frequent though underdiagnosed condition among Cuban adolescents. Most of the risk factors identified are modifiable. Currency of the findings rests on the fact that short-term variations are not typically found in the dynamics of chronic disease. A national baseline was developed which will permit evaluation of the effectiveness of prevention and control actions(AU)

Impacto de la inmunoterapia subcutánea con Dermatophagoides farinae y Dermatophagoides pteronyssinus sobre la calidad de vida de pacientes con rinitis y asma alérgica / The impact of subcutaneous immunotherapy with Dermatophagoides farinae and Dermatophagoides pteronyssinus on the quality of life of patients with allergic rhinitis and asthma

Introducción. Como sucede en otras partes del mundo, la prevalencia de asma y rinitis alérgica en Colombia está en aumento. Se ha establecido que la inmunoterapia subcutánea con alérgenos es eficaz a largo plazo en pacientes con rinitis alérgica y asma sensibilizados a Dermophagoides. Objetivo. Proveer evidencia sobre los cambios relacionados con la calidad de vida inducidos por la inmunoterapia subcutánea en sujetos con alergia respiratoria. Materiales y métodos. Se seleccionaron 76 sujetos con diagnóstico de alergia respiratoria con sensibilización a Dermatophagoides farinae y Dermatophagoides pteronyssinus . Para la evaluación de la calidad de vida se emplearon los instrumentos Kidscreen-27 y SF-36 ( Short form 36 ). Estos instrumentos se aplicaron en dos ocasiones: durante la primera visita, en la cual se iniciaba la inmunoterapia subcutánea, y un año después de haberse iniciado el tratamiento. Resultados. Al año de estar recibiendo la inmunoterapia, los 22 sujetos que completaron el estudio presentaron cambios positivos en términos de calidad de vida. En los niños, el principal cambio se presentó en el dominio del ´entorno escolar´ mientras que en los adultos fue en el de la ´función física´ . Discusión. Se evaluaron por primera vez en Colombia los beneficios inducidos por la inmunoterapia subcutánea para ácaros de polvo en la calidad de vida de sujetos con rinitis alérgica y asma mediante los cuestionarios Kidscreen-27 y SF-36. Los resultados proveen evidencia de que la inmunoterapia subcutánea influye positivamente en la calidad de vida en sujetos con rinitis asmática y asma sensibilizados a los ácaros de polvo.

Introduction: The prevalence of asthma and allergic rhinitis in Colombia is increasing at the same rate as it is in other parts of the world. It has been determined that allergen-specific subcutaneous immunotherapy is effective in subjects with allergic rhinitis and asthma that are sensitized to house dust mites: Dermatophagoides farinae and Dermatophagoides pteronyssinus . Objective: To provide evidence on changes in the quality of life of subjects induced by allergen-specific subcutaneous immunotherapy with Dermatophagoides farinae and Dermatophagoides pteronyssinus . Materials and methods: We selected 76 subjects with a diagnosis of respiratory allergy with sensitization to Dermatophagoides farinae and Dermatophagoides pteronyssinus . The instruments used for evaluating the quality of life were Kidscreen-27 and SF-36. These instruments were applied twice for each subject: once during the first visit, and during the twelfth visit corresponding to the one-year follow-up. Results: Twenty-two subjects completed this study. After one year of treatment with allergen-specific subcutaneous immunotherapy, we found positive changes in terms of the quality of life. In children, the main change was in the School Environment domain while in adults it was in the Physical Function domain. Conclusion: We evaluated, for the first time in Colombia, benefits induced by allergen-specific subcutaneous immunotherapy for dust mites in terms of quality of life in subjects with allergic rhinitis and asthma. These results demonstrated that allergen-specific subcutaneous immunotherapy produces a positive influence on subjects sensitized to dust mites that received allergen-specific subcutaneous immunotherapy to Dermatophagoides farinae and Dermatophagoides pteronyssinus after one year.

Efficacy and Safety of Montelukast Plus Fexofenadine Fixed Dose Combination in Allergic Rhinitis : Results of Post-Marketing Study In India.

Background:Allergic rhinitis is one of the most common conditions in clinical practice. Motelukast and second generation antihistamine fexofenadine are routinely used in the management of allergic rhinitis. Individually both drugs have been found to be effective in allergic rhinitis. Fixed dose combination of montelukast 10 mg plus fexofenadine 120 mg is available in India is also used in the treatment of allergic rhinitis. Objective: To evaluate the efficacy and safety of montelukast and fexofenadine fixed dose combination in the management of patients with allergic rhinitis. Material and methods: Post marketing observational study was conducted in 809 patients from all over India. All the patients were treated with montelukast 10 mg plus fexofenadine 120 mg fixed dose combination once daily for 14 days. The primary outcome criteria was the change in total symptom score (Sum of total nasal symptom score and total ocular symptom score) at the end of study compared to baseline. The secondary outcome criteria included change in total nasal symptom score (nasal congestion, rhinorrhea, nasal itching, and sneezing) and total ocular symptom score (Itching/burning eyes, tearing/ watering eyes and eye redness) at the end of study compared to baseline and physician’s and patient’s global assessment for efficacy and tolerability. The patients were evaluated at baseline, day 7 and day 14 for efficacy evaluation while the safety parameters were assessed at screening and day 14. Results: The fixed dose combination of fexofenadine plus montelukast was significantly effective in reducing total symptom score, total nasal symptom score and total ocular symptom score (p<0.0001 for all parameters). The global assessment of efficacy evaluation by both patient and investigators demonstrated “excellent to good” efficacy in >95% of patients. Most of the study population reported “good” tolerability with the fixed drug combination. No adverse events were reported in the study. Conclusion: The fixed dose combination of fexofenadine plus montelukast was found to be efficacious and well tolerated in allergic rhinitis in Indian adult patients.

Comorbidade asma e rinite alérgica: inter-relações entre as vias aéreas superiores e inferiores / Asthma and allergic rhinitis comorbidity: interactions between upper and lower airways

Objetivo: revisar a literatura sobre as inter-relações entre as vias aéreas superiores e inferiores, com enfoque na asma e na rinite alérgica. Métodos: pesquisa não sistemática realizada nas bases Medline e LILACS nos últimos 20 anos, usando os descritores "asthma" "allergic rhinitis" "interaction" "united airways". Resultados: vários estudos clínicos, epidemiológicos, experimentais sugerem a hipótese de que asma e rinite alérgica são a expressão de uma única doença que acomete as vias aéreas. Pacientes com asma frequentemente apresentam rinite alérgica e a rinite alérgica não tratada dificulta o controle da asma. Do ponto de vista histológico, as mucosas nasais e brônquicas compartilham várias semelhanças. Alterações da mucosa nasal causam alterações mediadas por respostas fisiológicas na mucosa brônquica, e vice-versa. Esse corpo de evidências culminou com a iniciativa ARIA (Allergic Rhinitis and its Impact on Asthma), que enfatiza a necessidade de tratar a rinite alérgica no paciente com asma. Conclusões: a hipótese de que asma e rinite alérgica são a expressão de uma única doença que acomete o trato respiratório tem se consolidado e reforça a importância da busca por tratamentos que contemplem de forma integrada a comorbidade.

Objective: To review the literature about interactions between upper and lower airways with emphasis in asthma and allergic rhinitis. Methods: A non systematic review was conducted using Medline and LILACS in the last twenty years, using "asthma" "allergic rhinitis" "interaction" "united airways" as descriptors. Results: Several clinical, epidemiological, experimental studies suggest the hypothesis that asthma and allergic rhinitis are the expression of a single disease that affects the airways. Patients with Asthma often have allergic rhinitis, and untreated allergic rhinitis make asthma control difficult. From the histological point of view, the nasal and bronchial mucosa share many similarities. Changes in the nasal mucosa cause changes in bronchial mucosa, mediated by physiological responses and vice-versa. These findings led to the initiative (ARIA) Allergic Rhinitis and its Impact on Asthma, that emphasizes the need to treat allergic rhinitis in patients with asthma. Conclusions: The hypothesis that allergic rhinitis and asthma are the expression of a single disease that affects the respiratory tract has been strengthened and reinforced the importance of searching for integrated treatments that aim the seamless comorbidity (AU)
