IntroductionDefinition No consensual definition: 1 Different disease: lack of response to usual treatment2: 1) resistance to corticosteroids (CS) 2) altered response to CS because of modified airways structure.

Introduction Characteristics of severe/ difficult to treat asthma patients • Predominance of female1 • High level of corticosteroids use3 • Increased in healthcare utilization1 • High level of neutrophils in sputum1 • High number of activated T lymphocytes4 1) Wenzel S.E., A different disease, many diseases or mild asthma gone bad?

Introduction Characteristics of severe/ difficult to treat asthma patients • Chronic airway inflammationcentral and peripheral5 • High air-trapping and obstruction1 • Low diffusing capacity1 • Forced expiratory volume during the first second (FEV1) ≤60% of predicted6 • Peak expiratory flow (PEF) variability over 30%6 • Wenzel S.E., A different disease, many diseases or mild asthma gone bad?

IntroductionRationale • Psychological aspects of severe/ difficult to treat asthma have been insufficiently studied7; • Psychosocial problems are a known risk factor for dying from asthma8; • High costs of the severe asthma due to hospitalizations, emergency and domiciliary care7. 7) Osborne M., Deffebach M., The Epidemiology and Natural History of Asthma Outcomes and Treatment Regimens (TENOR)Study, Annals of Allergy, Asthma and Immunology, 2004 8) Barton C.A., McKenzie D.P., Walters E.H., Abramson M.J., Interactions between psychosocial problems and management of asthma: who is at risk of dying?, The Journal of asthma, May 2005; 42(4):249-56
Introduction Aims of the study To compare psychological and social characteristics in adult patients with severe asthma and patients with mild to moderate asthma; Relevant Questions that may be answered in this study • Is depression related to severe asthma? • Is there any relation between anxiety scores and the severity of asthma? • Is there any association between severe asthma and the age of severe asthma patients? • Is social status related to severe asthma? • Is there any relation between schooling and the severity of asthma? • May factors as age and gender cause overfitting?
Instruments • Self-Anxiety (Zung, 1975) • Depression Inventory (Beck, 1961) • Asthma Control Questionnaire (Juniper, 1999) • Mini-Asthma Quality of Life Questionnaire (Juniper, 1998) • Spirometry • Peak Expiratory Flow (PEF) • Forced Expiratory volume in 1st second (FEV1)

Inconsistent results Social-economic status: Low social status may determine worse physical condition, wich explain frequent emergency care (10) , but not influence severity of asthma Depression: Depressive symptoms associated with asthma severity (10) Severe asthma individuals with low levels of depression after asthma treatment (12) Depression is a heavier factor in the severity of asthma than anxiety (11) Lavoie, K.L., Cartier, A., Labrecque, M., Bacon, S.L., Lemière, C., Malo, J.-L., Lacoste, G., (...), Ditto, B.Are psychiatric disorders associated with worse asthma control and quality of life in asthma patients?
