RATIONALE:

Smoking is one of the most significant triggers for asthma patients. The aim of this study was to evaluate the differences between smoker asthma (S) patients with non-smoker (NS) and ex-smoking (ES) patients in terms of symptoms, risk factors and comorbidities.

METHODS:

A web-based data entry of 500 patients living in the urban area of Istanbul/Turkey who were followed for at least one year after asthma diagnosis was made via Microsoft Access 2013. The registered respiratory symptoms, habits, risk factors, comorbidities of NS, ES, and S patients were compared statistically.

RESULTS:

Number and percentage of the NS, ES and S groups and their mean age were respectively 353 (70.6%) 39.9 ± 15.4; 88 (17.6) 44.8 ± 12.7; and 59 (11.8%) 38.0 ± 15.4. No group difference was found between cough, wheeze, chest tightness and dyspnea symptoms; asthma ratios in parents; body mass index; non-steroid anti-inflammatory hypersensitivity; pollen, mite, mold, pet sensitivity; heating methods in both home and workplace; allergic conjunctivitis, rhinitis and or sinusitis comorbidities (p>0.05). Percentage of allergic dermatitis and hypertension was lower in NS group (3.4%, 3.4% respectively) compared to ES and S groups (12.7% 17% and 13.9%, 10.2% respectively with p<0.02, p<0.03) and reflux was lower in S group (41.6%) compared to other groups (59.1%; 57.6% with p<0.003).

CONCLUSIONS:

Smoker and ex-smoker asthma patients of the urban area had similar asthma symptoms and risk factors but they had higher hypertension and allergic dermatitis comorbidities than non-smoker asthma patients.
