ABSTRACT

OBJECTIVES: The aim of this cross-sectional study was to evaluate whether interleukin 10 (IL10) and transforming growth factor β1 (TGFβ1) gene polymorphisms were associated with persistent IgE-mediated cow's milk allergy in 50 Brazilian children. The diagnostic criteria were anaphylaxis triggered by cow's milk or a positive double-blind, placebo-controlled food challenge. Tolerance was defined as the absence of a clinical response to a double-blind, placebo-controlled food challenge or cow's milk exposure. METHOD: The genomic DNA of the 50 patients and 224 healthy controls (HCs) was used to investigate five IL10 gene polymorphisms (-3575A/T, -2849A/G, -2763A/C, -1082G/A, -592C/A) and one TGFβ1 polymorphism (-509C/T). RESULTS: Among the five IL10 polymorphisms analyzed, homozygosis for the G allele at the -1082 position was significantly higher in the patients compared with the healthy controls (p = 0.027) and in the persistent cow's milk allergy group compared with the healthy controls (p = 0.001). CONCLUSIONS: Homozygosis for the G allele at the IL10 -1082G/A polymorphism is associated with the persistent form of cow's milk allergy. .

ABSTRACT

OBJETIVO: Avaliar a associação entre obesidade e asma pela comparação entre idade, gênero, classificação inicial e controle da asma, valores de volume expiratório forçado no primeiro segundo (VEF1) e fluxo expiratório forçado entre 25 e 75% (FEF25-75%) basais com os índices de massa corpórea (IMC) em adolescentes asmáticos. MÉTODOS: Estudo transversal envolvendo 120 pacientes (1,9 masculino:1 feminino) asmáticos com mediana de idade de 14,1 anos (9 a 20,1 anos), classificados quanto ao controle e gravidade da asma e avaliados pela espirometria utilizando VEF1 e FEF25-75% basais. Esses dados foram descritos pela frequência, médias e desvio padrão ou medianas e variação, sendo analisados pelos testes de ANOVA, teste t não pareado, teste exato de Fisher, Kruskal-Wallis e pela correlação de Pearson, considerando-se significante p<0,05. RESULTADOS: Não houve diferença entre os gêneros em relação à classificação inicial da asma e ao nível de controle. Receberam classificação inicial persistente 91,7% (100 casos), sendo que 106 casos (88,3%) encontravam-se parcial ou totalmente controlados. Não houve diferença estatística entre os pacientes controlados e os demais em relação ao IMC. Não foram encontradas correlações significantes entre zIMC e VEF1 e entre zIMC e FEV25-75%, analisando-se todos os pacientes e apenas pacientes com sobrepeso ou obesos. CONCLUSÕES: Neste estudo, não foi encontrada correlação significante entre sobrepeso/obesidade e asma, utilizando-se parâmetros clínicos, antropométricos e espirométricos.


OBJECTIVE: To relate obesity and asthma by comparing gender, age, initial classification of asthma, clinical control, basal forced expiratory volume in one second (FEV1) and forced expiratory flow between 25 and 75% (FEF25-75%) with rates of body mass index (BMI) in asthmatic adolescents. METHODS: Cross-sectional study involving 120 asthmatics patients (1.9 male: 1 female) with a mean age of 14.1 years (9 to 20.1 years of age), classified according to asthma severity and control, and evaluated by spirometry using their basal FEV1 and FEF25-75%. The data were described by frequency, mean and standard deviation or median and range and analyzed by ANOVA, unpaired t test, Fischer's exact test, Kruskal-Wallis and Pearson's correlation, considering significant p​​​​<0.05. RESULTS: There was no difference between gender in relation to the initial classification and the level of asthma control; 91.7% (100 cases) received initial classification as persistent and 106 cases (88.3%) were partially or totally controlled. There was no statistical difference between controlled patients and the others in relation to BMI. No significant correlations were found between zBMI and FEV1 and between zBMI and FEF25-75%, analyzing all patients and only patients with overweight or obese. CONCLUSIONS: In this study, no significant correlation was found between overweight/obesity and asthma using clinical, anthropometric and spirometric parameters.


OBJETIVO: Evaluar la asociación entre obesidad y asma por la comparación entre edad, género, clasificación inicial y control del asma, valores de volumen espiratorio forzado en el primer segundo (VEF1) y flujo espiratorio forzado entre 25 y 75% basal (FEF25-75%) con los índices de masa corporal (IMC) en adolescentes asmáticos. MÉTODOS: Estudio transversal implicando a 120 pacientes (1,9M:1F) asmáticos con mediana de edad de edad de 14,1 años (9 a 20,1 años), clasificados respecto al control y gravedad del asma, y evaluados por la espirometría utilizando su VEF1 y FEF25-75% basales. Estos datos fueron descriptos por la frecuencia, promedios y desviaciones estándar o medianas y variación y analizados por las pruebas de ANOVA, prueba t no pareada, Prueba exacto de Fisher, Kruskal-Wallis y por la correlación de Pearson considerándose significantes valores de p<0,05. RESULTADOS: No hubo diferencia entre los géneros respecto a la clasificación inicial del asma y el nivel de control. Recibieron clasificación inicial persistente 91,7% (100 casos), siendo que 106 casos (88,3%) estaban parcial o totalmente controlados. No hubo diferencia estadística entre los pacientes controlados y los restantes respecto al IMC. No se encontraron correlaciones significantes entre zIMC y VEF y entre zIMC y FEF25-75% al analizar todos los pacientes y solamente los pacientes con sobrepeso u obesos. CONCLUSIONES: En este estudio, no fue encontrada correlación significante entre sobrepeso/obesidad y asma, utilizándose parámetros clínicos, antropométricos y espirométricos.
