The Impact of Allergic Rhinitis on Asthma and Its Effect on the Quality of Life of Asthmatic Patients

Background Allergic rhinitis (AR) and asthma are one of the most common diseases in the Kingdom of Saudi Arabia. Asthma and AR patients report significant reductions in their daily activities due to this condition. Therefore, measuring health-related quality of life (HRQOL) in adult asthmatic and AR patients and evaluating the use of allergic rhinitis treatment modalities to improve asthma control may help prevent future respiratory complications, improve patient quality of life, and reduce morbidity. Methods This cross-sectional observational study was conducted through an online self-administrated questionnaire distributed electronically on social media through “Survey Monkey” (http://www.surveymonkey.com) from April 2 to September 18, 2021. The study targeted adult patients with asthma and/or allergic rhinitis residing in the Riyadh region of Saudi Arabia. The study compared and evaluated HRQOL between three groups: asthmatic patients with concomitant AR, patients with asthma only, and patients with AR only. Results A total of 811 questionnaires were analyzed. Of those, 23.1% were diagnosed with asthma and 64% were diagnosed with allergic rhinitis; from those who were diagnosed with AR, 27.2% were asthmatics. A statistically significant association was observed between receiving AR medications and asthma control in respondents with intermittent AR (P < 0.001). However, no association was observed between asthma control and receiving medications for AR in respondents with persistent AR (P = 0.589). The average scores for all eight-item short-form (SF-8) QOL dimensions were lower in patients with combined asthma and AR than in patients with AR only and asthma only (P < 0.001). Conclusions This study suggested that AR was associated with more severe asthma and quality of life impairment.
