RT Journal Article SR Electronic T1 Utility of routine screening for alpha-1 antitrypsin deficiency in patients with bronchiectasis JF Thorax JO Thorax FD BMJ Publishing Group Ltd and British Thoracic Society SP 592 OP 593 DO 10.1136/thoraxjnl-2019-214195 VO 75 IS 7 A1 Carreto, Luis A1 Morrison, Meghan A1 Donovan, Jackie A1 Finch, Simon A1 Tan, Gan Liang A1 Fardon, Tom A1 Wilson, Robert A1 Furrie, Elisabeth A1 Loebinger, Michael A1 Chalmers, James D YR 2020 UL http://thorax.bmj.com/content/75/7/592.abstract AB Alpha-1 antitrypsin deficiency (AATD) is a cause of bronchiectasis. Guidelines for bronchiectasis from the British Thoracic Society do not recommend to routinely test patients for AATD. In contrast, guidelines for AATD recommend routine screening. This contradiction, in part, results from the lack of data from large studies performing comprehensive screening. We screened 1600 patients with bronchiectasis at two centres in the UK from 2012 to 2016. In total, only eight individuals with AATD were identified representing 0.5% of the overall population. We conclude that routine screening for AATD in bronchiectasis in the UK has a low rate of detection. Further studies are required in different geographical regions, which may have a higher prevalence of AATD.
