STUDY OBJECTIVES: Patients with obstructive sleep apnea (OSA) have been shown to have high levels of inflammatory markers. Anti-inflammatory treatment with montelukast and intranasal steroids have demonstrated efficacy for mild OSA in children; this has not been fully evaluated in adults. This study investigated the response of mild OSA in adults to anti-inflammatory medical therapy.

METHODS: Adults aged ≥ 21 years with an apnea-hypopnea index (AHI) ≤ 15 events/h on polysomnography (PSG) were recruited to a prospective double-blind, randomized control trial. Patients were treated for 12 weeks with montelukast and fluticasone or placebo. All underwent a pretreatment and posttreatment PSG. Epworth Sleepiness Scale (ESS) score was obtained pretreatment and at 6 and 12 weeks posttreatment.

RESULTS: A total of 26 patients completed the study with 13 in each group. Mean age in the treatment and placebo groups were 58.3 ± 10.3 and 54.8 ± 14 years, respectively. There was no significant difference between groups reporting nasal congestion ( = .186), rhinitis ( = .666), or snoring ( = .177). There was no difference in the pretreatment ESS score ( = .077), body mass index ( = .173), or AHI ( = .535). The posttreatment PSG in the treatment group demonstrated a significant increase in total sleep time ( = .02) and percent of stage R sleep ( = .05). Neither group showed significant change in AHI. In patients in the treatment group, the 6- and 12-week follow-up ESS scores were not significantly different from pretreatment scores ( = .37-.46).

CONCLUSIONS: Intranasal steroids and montelukast did not decrease AHI; however, total sleep time and percent of stage R sleep significantly increased. Self-reported improvement could be explained by observed changes in sleep parameters. Larger prospective studies could help elucidate the effects of medical therapy on adult patients with OSA.
