The effects of dust storms on quality of life of allergic patients with or without asthma

Abstract

Objectives: This study aims to investigate the quality of life of allergic patients with or without asthma during dust storms.

Patients and methods: A total of 148 allergic patients (66 males, 82 females; mean age 35.7±15.5 years; range 18 to 65 years) were classified as those with (group 1, n=80) or without (group 2, n=68) concomitant asthma between January 2012 and January 2013. The quality of life [Short Form-36 (SF-36)] scores, Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ), nasal symptom and visual analog scale (VAS) scores at the time of diagnosis were obtained. The particulate matter (PM10) and sulfur dioxide (SO2) values of that day from the General Directorate of Meteorology were recorded. The day of dust storm and PM10 and SO2 measurements along with SF-36, RQLQ, nasal symptom and VAS scores were recorded again.

Results: The absolute change in the RQLQ subparameters including eye and nasal symptoms, practical problems and global scores was statistically significant (p=0.022, p=0.036, p=0.026 and p=0.032, respectively). There were statistically significant changes in the SF-36 subgroups of general health, physical functioning, vitality, and mental health (p=0.026, p=0.042, p=0.008 and p=0.026, respectively). In the multivariate logistic regression model, specific and general quality of life was 4.6 times worse in RQLQ and 3.8 times in SF-36 after the dust storm in patients with asthma, while 2.1 times worse in RQLQ and 1.9 times in SF-36 in patients with pure allergic rhinitis. The attributable risk of asthma was found to be 2.5 times higher in RQLQ and 1.9 times higher in SF-36.

Conclusion: Dust storms may deteriorate the quality of life of patients with allergic rhinitis and asthma and lead to related personal and societal problems.
