RESUMO

RESUMEN Introducción: La Bronquiolitis se ha asociado a sibilancias recurrentes. Objetivo: analizar la incidencia de sibilancias recurrentes, hospitalizaciones y atopia/asma en pacientes con antecedentes de hospitalización por bronquiolitis por RV antes de los 12 meses de edad. Materiales y Métodos: estudio de cohorte retrospectiva. Ingresaron pacientes de 2 a 4 años con sibilancias recurrentes y antecedentes de hospitalización por bronquiolitis antes de los 12 meses de edad, con retorno viral positivo por estudio molecular. Fueron estudiados los datos demográficos, hospitalizaciones, atopia personal y familiar, asma y exposición al humo. Los datos fueron analizados en SPSS utilizando estadísticas descriptivas e inferenciales. Los resultados se expresaron en RR con IC 95%. El protocolo fue aprobado por el comité de ética institucional. Resultados: Ingresaron 120 pacientes. No hubo diferencias en la incidencia de sibilancias recurrentes en el grupo expuesto y el control50,9% vs 49% respectivamente p=0,85. Las hospitalizaciones por sibilancias y la presencia de atopia fueron más frecuentes en el grupo Rinovirus, RR=1,7 (IC 95% 1,2 -2,9) p=0,03 y RR 1,6 (IC 95% 1,2 -2,2) p= 0,005 respectivamente. Conclusiones: la incidencia de sibilancias recurrentes fue similar en ambas cohortes. Las hospitalizaciones por sibilancias y la atopia/asma fue mayor en el grupo Rinovirus.


ABSTRACT Introduction: Bronchiolitis has been associated with recurrent wheezing. Objective: to analyze the incidence of recurrent wheezing, hospitalizations and atopy / asthma in patients with a history of hospitalization for rhinovirus (RV) bronchiolitis before 12 months of age. Materials and Methods: this was a retrospective cohort study. We included patients aged 2 to 4 years with recurrent wheezing and a history of hospitalization for bronchiolitis before 12 months of age, with a positive viral testing by molecular study. Demographic data, hospitalizations, personal and family history of atopy, asthma and exposure to smoke were studied. The data were analyzed in SPSS using descriptive and inferential statistics. The results were expressed in RR with 95% CI. The protocol was approved by the institutional ethics committee. Results: 120 patients were included. There were no differences in the incidence of recurrent wheezing in the exposed and control groups, 50.9% vs 49%, respectively, p = 0.85. Hospitalizations for wheezing and the presence of atopy were more frequent in the Rhinovirus group, RR = 1.7 (95% CI 1.2 -2.9) p = 0.03 and RR 1.6 (95% CI 1, 2 -2.2) p = 0.005 respectively. Conclusions: the incidence of recurrent wheezing was similar in both cohorts. Hospitalizations for wheezing and atopy / asthma were higher in the Rhinovirus group.
