Abstract

Inflammation disease of the airway such as obstructive sleep apnea and asthma are linked with each other. We conducted a cross-sectional descriptive examination on 54 asthmatic children from 6 to 17 years old, managed at the National Children's Hospital to determine the rate of obstructive sleep apnea and describe the clinical and subclinical characteristics of this special group. Obstructive sleep apnea was diagnosed by respiratory polygraphy. 29/54 (53.7%) asthmatic children of 8.38 years old have obstructive sleep apnea, of which 26/29 (89.65%) children had mild and moderate persistent asthma with increased FENO (21.55 ± 19).0 ppb). 17/29 (58.62%) asthmatic children had mild obstructive sleep apnea, moderate persistent asthmatic children had higher prevalence of moderate obstructive sleep apnea (41.38% vs 13.79%, p< 0.05). OSA diagnosis and treatment is essential for the management of asthmatic children.
