OBJECTIVE: Initiation of continuous positive airway pressure (CPAP) in children with severe obstructive sleep apnea syndrome (OSAS) is challenging and the distinct features of the subset of children requiring CPAP are poorly defined. Asthma often coexists with OSAS in children. The goal of this study was to explore the influence of asthma in the need for CPAP therapy in children with severe OSAS. HYPOTHESIS: Asthmatic children with severe OSAS have higher probability of needing CPAP than children with severe OSAS without asthma. METHODS: Cross-sectional study of clinical presentation, individual risk factors, and initial overnight polysomnogram (PSG) parameters in children with severe OSAS. Severe OSAS was defined as an obstructive apnea hypopnea index ≥10/h. The association between asthma and CPAP initiation was studied individually and adjusted by pertinent covariates. RESULTS: Four hundred eligible children (mean age 7 years, ±SD 5.3) with severe OSAS were enrolled and 133 individuals (33%) were identified to have asthma. The proportion of children needing CPAP was significantly higher in asthmatics with severe OSAS (29%) compared to those with OSAS alone (14%) (P < 0.01). Multivariate analysis demonstrated that the association between asthma and the need of CPAP in pediatric severe OSAS was independent of demographics, OSAS severity, obesity, and history of adenotonsillectomy (P < 0.01). CONCLUSION: Asthmatic children with severe OSAS have higher probability of needing CPAP independent of relevant covariables. This study further substantiates the link between OSAS and asthma in children and suggests the diagnosis of asthma may influence the need of CPAP therapy for severe OSAS.
