- Brief Summary
Obstructive sleep apnea (OSA) in children is a disorder of breathing during sleep characterized by prolonged partial upper airway obstruction and/or intermittent complete obstruction (obstructive apnea) that disrupts normal breathing during sleep1. The condition occurs in 2-5% of children and can occur at any age, but it is most common in children between the ages of 2 to 62,3. Untreated OSA is associated with lung disease, heart disease, growth delay, poor learning and behavioral problems such as inattention and hyperactivity. The most common underlying risk factor for the development of OSA is enlargement of tonsils and adenoids. Given the potential risk of complications associated with surgery of the tonsils and adenoids, medications to shrink the adenoids without requiring surgery have been considered, in particular intranasal corticosteroids (INCSs) which is a nose spray. A recent Cochrane systematic review suggested a short-term benefit of INCSs in children with mild to moderate OSA4. The authors recommended that further randomised controlled studies were required to evaluate the efficacy of INCSs in children with OSA. In particular they recommended that future studies should employ sleep studies to look for any improvement with INCSs, and should include children with more severe OSA, as these are the patients at the greatest risk of complications of surgery and would benefit most from a non-surgical treatment. The purpose of this study is therefore to explore the efficacy of INCSs in children with the full spectrum of OSA severity, including sleep study analysis., and longer term follow-up.

Group Intervention Description Nasonex Mometasone furoate nasal spray The intervention group will receive mometasone nasal sprays at the dosage outlined below for 8 weeks. For patients that are between age 3 to 11 years and if they are randomized to the medicated group, they will use pediatric dosing of Mometasone nasal sprays, 1 spray (50 mcg) in each nostril once daily for 8 weeks. For patients that are older than age 12 and if they are randomized to the medicated group, they will use adult dosing of Mometasone nasal sprays, 2 sprays (100mcg) in each nostril twice daily for 8 weeks. Saline Placebo The placebo group will receive saline nasal sprays for 8 weeks.
- Primary Outcome Measures
Name Time Method Apnea Hypopnea Index (AHI) 8 weeks This wil be measured by polysomnography.
- Secondary Outcome Measures
Name Time Method Mean arterial oxygen saturation At baseline and after each phase of treatment (i.e. after initial 8 weeks invention and again after second 8 weeks intervention) This will be measured by polysomnography.
Respiratory Disturbance Index At baseline and after each phase of treatment (i.e. after initial 8 weeks invention and again after second 8 weeks intervention) This will be measured by polysomnography.
Desaturation index At baseline and after each phase of treatment (i.e. after initial 8 weeks invention and again after second 8 weeks intervention) This will be measured by polysomnography.
Nadir of arterial oxygen saturation At baseline and after each phase of treatment (i.e. after initial 8 weeks invention and again after second 8 weeks intervention) This will be measured by polysomnography.
Avoidance of surgical treatment for OSA At baseline and after each phase of treatment (i.e. after initial 8 weeks invention and again after second 8 weeks intervention) This will be measured by polysomnography.
Clinical symptom score (based on parent repot of, for example, snoring, witnessed apnea, daytime sleepiness etc.) At baseline and after each phase of treatment (i.e. after initial 8 weeks invention and again after second 8 weeks intervention) This will be measured by polysomnography.
Respiratory arousal index At baseline and after each phase of treatment (i.e. after initial 8 weeks invention and again after second 8 weeks intervention) This will be measured by polysomnography.
Tonsillar size (on an ordinal scale from 0 [not visible] to +4 [tonsils touch]) At baseline and after each phase of treatment (i.e. after initial 8 weeks invention and again after second 8 weeks intervention) This will be measured by polysomnography.
