RESUMEN

OBJECTIVE: To determine whether polymorphisms of the IL10 and IL17 genes are associated with severe asthma control and bronchodilator reversibility in children and adolescents with severe asthma. METHODS: This was a cross-sectional study, nested within a prospective cohort study of patients with severe asthma. Two outcomes were evaluated: asthma control and bronchodilator reversibility. We extracted DNA from peripheral blood and genotyped three single nucleotide polymorphisms: rs3819024 and rs2275913 in the IL17A gene; and rs3024498 in the IL10 gene. For the association analyses, we performed logistic regression in three genetic models (allelic, additive, and dominant). RESULTS: The rs3024498 C allele in the IL10 gene was associated with failure to achieve asthma control despite regular treatment (p = 0.02). However, the G allele of the IL17A rs3819024 polymorphism was associated with failure to respond to stimulation with a b2 agonist. The rs2275913 polymorphism of the IL17A gene showed no relationship with asthma control or bronchodilator reversibility. CONCLUSIONS: In pediatric patients with severe asthma, the IL10 polymorphism appears to be associated with failure to achieve clinical control, whereas the IL17A polymorphism appears to be associated with a worse bronchodilator response. Knowledge of the involvement of these polymorphisms opens future directions for pharmacogenetic studies and for the implementation of individualized therapeutic management of severe asthma in pediatric patients.

RESUMO Objetivo: Determinar se existe relação entre polimorfismos dos genes IL10 e IL17 e controle da asma grave e reversibilidade com broncodilatador em crianças e adolescentes com asma grave. Métodos: Estudo transversal, aninhado em um estudo prospectivo de coorte com pacientes com asma grave. Foram avaliados dois desfechos: controle da asma e reversibilidade com broncodilatador. Extraímos DNA do sangue periférico e genotipamos três polimorfismos de nucleotídeo único: rs3819024 e rs2275913 no gene IL17A e rs3024498 no gene IL10. Para as análises de associação, realizamos regressão logística em três modelos genéticos (alélico, aditivo e dominante). Resultados: O alelo C do polimorfismo rs3024498 do gene IL10 apresentou relação com asma que permaneceu descontrolada mesmo com tratamento regular (p = 0,02). No entanto, o alelo G do polimorfismo rs3819024 do gene IL17A apresentou relação com ausência de resposta ao estímulo com b2-agonista. O polimorfismo rs2275913 do gene IL17A não apresentou relação com controle da asma ou reversibilidade com broncodilatador. Conclusões: Em pacientes pediátricos com asma grave, o polimorfismo do gene IL10 parece estar relacionado com ausência de controle clínico, ao passo que o polimorfismo do gene IL17A parece estar relacionado com pior resposta ao broncodilatador. O conhecimento a respeito do envolvimento desses polimorfismos abre perspectivas futuras para estudos farmacogenéticos e para a implantação de manejo terapêutico individualizado da asma grave em pacientes pediátricos.

RESUMEN

OBJECTIVE: To evaluate the effectiveness of home visits in a group of children and adolescents with severe asthma by using the inhalation technique score and adherence rates to drug treatment. METHOD: A 12-month randomized controlled trial involving patients aged between three and 17 years under regular follow-up treatment at a pediatric pulmonology outpatient clinic of a university hospital in southeastern Brazil. A group of patients received only outpatient consultations and the other group received home visits from nurses in addition to outpatient consultations. The differences between groups were analyzed through the outcomes of inhalation technique scores and treatment adherence rate. RESULTS: Participation of 29 patients. In the intervention group, there was a statistically significant increase in inhalation technique scores (p<0.05) and elimination of critical errors between the first and the second evaluation, and results were maintained in the third evaluation. In the control group, there were no significant changes in inhalation technique scores. Rates of adherence to drug treatment in both groups did not rise. CONCLUSION: Home visits were effective for improving inhalation technique scores in patients with severe asthma. Brazilian Registry of Clinical Trials: RBR-8GZWZP.

Resumen Objetivo: Evaluar la efectividad de la visita domiciliaria en un grupo de niños y adolescentes con asma severa, utilizando el score de la técnica inhalatoria y las tasas de adhesión al tratamiento medicamentoso. Método: Estudio experimental randomizado controlado, con duración de 12 meses, que incluyó a pacientes con edades entre tres y 17 años, acompañados regularmente en un ambulatorio de neumología pediátrica de un hospital universitario de la región Sureste de Brasil. Un grupo de pacientes recibió solo consultas ambulatorias y el otro grupo, además de las consultas ambulatorias, recibió visitas de la enfermera en el hogar. Fueron analizadas las diferencias entre los grupos en los resultados: scores de la técnica inhalatoria y tasa de adhesión al tratamiento. Resultados: Participaron 29 pacientes. En el grupo intervención, hubo aumento estadísticamente significativo de los scores de la técnica inhalatoria (p<0,05) y eliminación de errores críticos de la primera a la segunda evaluación, resultados que se mantuvieron en la tercera. No hubo modificaciones significativas en la técnica inhalatoria del grupo de control. Las tasas de adhesión al tratamiento medicamentoso en ambos grupos no se elevaron. Conclusión: La visita domiciliaria fue eficaz en mejorar los scores de técnica inhalatoria en pacientes con asma severa. Registro Brasileño de Ensayos Clínicos: RBR-8GZWZP
