Asthma severity - GINA 2002 Asthmaseverity • Control • Symptoms • Functional limitation • over 2-4 weeks • Exacerbations over 6-12 mo
Classification of asthma: GINA 1998 Current treatment step Step 1 No controller Step 2 <500 BDP Step 3 200–1000 BDP + LABA Step 4 >1000 BDP + LABA + other Clinical features Severe persistent Moderate persistent Step 1 Symptoms <1 x week Nocturnal symptoms ≤2x month Lung function normal between episodes Intermittent Mild persistent Step 2 Symptoms >1 x week Nocturnal symptoms <1 x week Lung function normal between episodes Severe persistent Severe persistent Moderate persistent Mild persistent Step 3 Symptoms daily Nocturnal symptoms ≥1 x week FEV1 60–80% predicted Moderate persistent Severe persistent Severe persistent Severe persistent Severe persistent Severe persistent Step 4 Symptoms daily Frequent nocturnal symptoms FEV1 <60% predicted Severe persistent Severe persistent
Asthma control - GINA 2006 Asthma control • Control • Symptoms • Functional limitation • over 2-4 weeks • Exacerbations over 6-12 mo
Asthma severity- NAEPP3 (NHLBI) Asthmaseverity • Control • Symptoms • Functional limitation • over 2-4 weeks • Exacerbations over 6-12 mo • Future risks • Asthma exacerbations • Lung functionloss • Lung growth in children • Adverse reactionsfrommedications) Responsiveness to treatment
Definition of severe asthma (Geneva, 6-7 April 2009)
Asthma severity WHO definition Bousquet J et al, J Allergy Clin Immunol 2010 Asthmaseverity • Control • Symptoms • Functional limitation • over 2-4 weeks • Exacerbations over 6-12 mo • Future risks • Asthma exacerbations • Lung function loss • Lung growth in children • Adverse reactions from medications) • Level of treatment • Inhalation technique • Compliance Responsiveness to treatment

Applicability of the definition • Public health: to improve the quality of allergy care, • but also to optimize health care planning and policies. • Clinical practice: simplicity for physicians • Clinical trials • Research: Well characterized approved phenotypes • Epidemiologic studies: Well characterized approved phenotypes • Drug development • Applicable to developed and developing countries • Registries
