Brief Summary
The Chairman of the Veterans' Disability Benefits Commission reported at a recent US Senate hearing that asthma, chronic obstructive pulmonary disease (COPD), and sleep apnea are among the top 13 most frequent diagnoses leading to disability under the Department of Defense and the VA system statutes. Recent research finds that sleep apnea is more common among asthma and COPD individuals, and this may be caused by inhaled corticosteroid use. Many Veterans are currently using inhaled corticosteroids, and many more will be prescribed such medications, given their recent inclusion in international treatment guidelines. As such, this study addresses a critical need by researching the role of a potent inhaled corticosteroid in promoting sleep apnea, the determinants of this response, and the ways through which it occurs. Results from this study will form the foundation for future research aimed at expanding understanding of the effects of inhaled corticosteroids on the upper airway, as well as developing means to prevent or counteract them.

Limitations and Caveats
Study was terminated early due to low accrual. The original scientific question remains unanswered. Based on the experience with this study, a multi-center study would be necessary to accrue sufficient participants to answer the question.
