Introductıon: Considerable overlaps exist between asthma phenotypes and the clinical significance of these overlaps remains undetermined. The objective of this study is to analyze the characteristics of asthma overlap phenotypes using data from the Turkish Adult Asthma Registry (TAAR). Methods: This cross-sectional registry study included 2053 adult patients (74.8% female) with asthma. Results: Overall, 39.3% (n = 697) had allergic–eosinophilic (AE), 26.0% (n = 461) had allergic–non-eosinophilic (ANE), 21.3% (n = 377) had non-allergic–eosinophilic (NAE), and 13.4% (n = 237) had non-allergic–non-eosinophilic (NANE) asthma. Severe asthma exacerbations and emergency department (ED) visits were more frequent in the AE (28.3%, 31.2%, respectively) and NAE groups (36.0%, 34.0%, respectively) than in the ANE (14.3%, 20.6%, respectively) and NANE groups (12.6%, 16.7%, respectively) (p < 0.001). FEV1 values were significantly lower in the AE group than in the ANE and NANE groups (p < 0.001, p = 0.048, respectively) and in the NAE group than in the ANE group (p < 0.001). Risk factors for poor asthma control included living in rural areas, asthma-related ED visits, FEV1 < 60% in the NAE; being overweight, chronic rhinosinusitis, oral corticosteroids use, age < 40 years in the NANE; FEV1 < 80% in the AE; and severe asthma exacerbations, ED visits for AE and ANE groups. Conclusıon: The considerable overlap between allergic and eosinophilic asthma phenotypes has clinical implications as increased rates of asthma exacerbations and healthcare utilization. The clinical heterogeneity among asthma phenotypes based on a single biomarker highlights the importance of multidimensional asthma phenotyping.

Background: Asthma is one of the most common causes of chronic respiratory disease, and countries with low socioeconomic status have both a high prevalence of asthma and asthma-related death. Objective: In this study, we aimed to determine socioeconomic levels of asthmatic patients according to a national database and investigate the effects of social markers on disease control in our region. Methods: This is an analysis of data from 2053 adult asthma patients from a multicentre chart study in Turkey. Socioeconomic status (SES) data were collected from questionnaires and this form was sent to the patients via e-mail. Parameters related to social status and poor disease control were analyzed. Results: Illiteracy (OR:2.687 [95% CI: 1.235–5.848]; p = 0.013) and lower household income (OR:1,76 [95% CI: 1.002–3.09]; p = 0.049) were found as independent risk factors for hospitalization in the multivariate logistic regression analysis. Therewithal, being aged between 40 and 60 (OR: 1.435 [95% CI: 1.074–1.917]; p = 0.015), illiteracy (OR: 2.188 [95% CI: 1.262–3.795]; p = 0.005) and being employed (OR: 1.466 [95% CI: 1.085–1.847]; p = 0.011) were considered as independent risk factors for systemic corticosteroid use at least 3 days within last 1 year. Conclusion: As a result of our national database, education level, household income and working status briefly socioeconomic status have impacts on asthma control. Identification of social markers in asthma and better recognition of risk factors based on the population gives us clues to provide better asthma control in the future.
