Therapeutic options for reducing sleep impairment in allergic rhinitis, rhinosinusitis, and nasal polyposis.

BACKGROUND

Patients with inflammatory disorders of the upper airways, such as allergic rhinitis, rhinosinusitis, and nasal polyposis, often have significant sleep disturbances. Poor sleep can lead to fatigue, daytime somnolence, impaired daytime functioning as reflected in lower levels of productivity at work or school, and a reduced quality of life. Although the exact mechanisms by which these inflammatory nasal conditions disturb sleep is not fully understood, congestion appears to be a key factor and is generally the most common and bothersome symptom for patients with these conditions. Successful therapy should improve patients' sleep and well-being without introducing any negative effects on sleep. SCOPE OF LITERATURE SEARCH: Literature searches of Medline, Embase, and abstracts from medical/scientific conferences were conducted for the period of 1995 through mid-2006 for primary and review articles and conference presentations about sleep disturbance related to allergic rhinitis, rhinosinusitis, and nasal polyposis. These searches also sought to identify articles examining how treatments for those diseases improved sleep and, consequently, patients' quality of life. Surveys of the impact of congestion on patients' quality of life and their sleep also were consulted. Clinical studies were selected for discussion if they were randomized, double-blind, and placebo-controlled. Limitations of this review include the absence of any direct comparisons of the effectiveness of different drugs on improving sleep and shortcomings in the statistical methods of the patient surveys.

RESULTS

Intranasal corticosteroids (INSs) are the most effective medication for reducing congestion in patients with inflammatory nasal conditions. There is a growing amount of evidence that a reduction in congestion with INSs is associated with improved sleep, reduced daytime sleepiness, and enhanced patient quality of life.

CONCLUSIONS

Relief of sleep impairment associated with inflammatory disorders of the nose and sinuses can be addressed with INS therapy.
