    • Abstract:
      Objective: Studies show high comorbidity of mood disorders in asthma. As asthma is a highly heterogeneous disease with different phenotypes it can be expected that there is a difference in this association with different asthma phenotypes. The aim of our cross-sectional study was to assess the association of specific asthma phenotypes with anxiety and/or depression and their impact on asthma control. Methods: A cross-sectional study in 201 consecutive adult outpatients with asthma (≥18 years of age) was conducted. Each patient underwent physical examination, detailed medical history, Hospital Anxiety and Depression Scale, Asthma Control Questionnaire, Asthma Control Test, together with measurements of lung function and fraction of exhaled nitric oxide. Phenotypes were assessed using cluster analysis, and a multivariate analysis was used to identify associations of mood disorders with different phenotypes. Results: Five asthma phenotypes were identified: allergic (AA, 43.8%), aspirin-exacerbated respiratory disease (AERD, 21.9%), late-onset (LOA, 18.9%), obesity-associated (OAA, 10.0%), and respiratory infections associated asthma (RIAA, 5.5%). A multivariate analysis showed a significant association of anxiety with LOA and comorbid hypertension (LOA, odds ratio (OR) = 2.12; hypertension, OR = 2.37, p = 0.012), and depression with AA, RIAA, hypertension, and ACQ score (AA, OR = 6.07; RIAA, OR = 4.73; hypertension, OR = 5.67; ACQ, OR = 1.87; p < 0.001). Comorbid anxiety/depression was associated with AA, LOA, RIAA, hypertension, and ACQ score (AA, OR = 10.15; LOA, OR = 2.98; RIAA, OR = 6.29; hypertension, OR = 5.15; ACQ, OR = 1.90; p < 0.001. Conclusion: Mood disorders were significantly associated with AA, LOA, and infection-associated asthma, together with comorbid hypertension and the level of asthma control. [ABSTRACT FROM AUTHOR]
