Background The revised 2011 GOLD strategy presented a new classification and treatment of usual Chronic Obstructive Pulmonary disease (COPD) based on symptom assessment by CAT or mMRC and risk assessment based on exacerbations estimated from the spirometric grade or number of exacerbations in previous year (1). This new strategy has not previously been applied to patients with Alpha one antitrypsin deficiency (AATD). Aims To apply new GOLD strategy/categories in AATD and assess comparable symptom thresholds and predictability of mortality, future exacerbations and lung function decline (FEV1, Kco) and the role of comorbidities. Results The results have validated the strategy/classification in AATD with a suggested threshold of 13 rather than 10 for CAT to match with mMRC 1. Mortality and Kco decline was worse in the more severe category D which also had patients with more comorbidity. Applying COTE index to patients with AATD did not help in predicting mortality. Conclusion The new GOLD classification helps identify AATD patients who are at risk of poorer outcome based on lung function decline, mortality and exacerbation risk with patients in group D being most at risk. Presence of comorbidities does not appear to influence outcomes in AATD although they do tend to indicate a poorer quality of life. References 1.
