Pitfalls in respiratory allergy management: alexithymia and its impact on patient-reported outcomes.

OBJECTIVES: Alexithymia is a personality trait characterized by a limited ability to identify and express emotions and it represents a possible risk factor for disease development and management. The objective of the study is to evaluate alexithymia in patients with persistent asthma and comorbid rhinitis and its relation with patient-reported outcomes (PROs). METHODS: Alexithymia, quality of life, illness perception, and stress were assessed, as well as rhinitis symptoms and asthma control in out-patients classified according to GINA and ARIA guidelines. RESULTS: Out of 115 patients, 19% turned out to be alexithymic (TAS-20 ≥ 61). Concerning alexithymia level, no difference was detected between males and females (χ(2) = 0.317) and among GINA levels (χ(2) = 0.22). Alexithymics had significantly lower Asthma Control Test scores when compared with non-alexithymics (15.86 vs. 19; p = .02). Alexithymics had a worse quality of life (p .001), and inertia (p < .001). CONCLUSION: Alexithymia is present in a relevant percentage of subjects and, as it can modulate illness perception, quality of life, and stress, it should be considered in disease management
