Abstract

Introduction: Allergic rhinitis (AR) is a disease affecting not only the nose and eye but also sleep and emotion, leading to impairment of daily activity.
Night-time symptoms with daytime sleepiness can directly or indirectly reduce performance at work or school. The aim of this study was to evaluate the night-time symptoms and daytime sleepiness among patients with AR.

Patients and methods: This study was conducted from March 2011 until March 2012 involving 354 patients with AR, aged between 12 and 75 years.
All patients were interviewed for night-time symptoms, and a validated Malay version of Epworth Sleepiness Scale (ESS) questionnaire was used. Clinical and nasoendoscopic examinations were done.

Results: Most patients with AR reported nasal obstruction as the most bothersome night-time symptoms (43.5%). Other bothersome night-time symptoms were nasal or eyes itchiness (37.3%), repeated sneezing (39.2%), rhinorrhoea (36.7%), headache (24.8%), and facial pain or pressure (18.3%). Most patients (71.2%) had ESS less than or equal to 10 (normal); 22.8% had mild daytime sleepiness (ESS=11–15) and 6.8% had severe daytime sleepiness (ESS>15).

Conclusion: The relationship between nasal obstruction and daytime sleepiness is significant (P=0.0036). The presence of nasal obstruction is an indicator of daytime sleepiness among patients with AR.

Keywords: allergic rhinitis, daytime sleepiness, night-time symptoms.
