These individuals are at significant risk of death and spirometric disease progression. This will need to be further studied and standardized as far as automated algorithms for calculation of emphysema and small airway disease and its practical application globally.

To date none of the trials with biologics have proven them to be efficacious in COPD patients.23-26 Interestingly, the GOLD committee has decided to cease from using the “asthma/COPD overlap” term and instead states that these are separate diseases that share some common characteristics and may coexist in an individual. doi: https://doi.org/10.7759/cureus.4985, 3. 2020 report. Lancet Respir Med. Four key disease characteristics - environmental exposure (cigarette smoking), clinical symptoms (dyspnea and/or chronic bronchitis), chest CT imaging abnormalities (emphysema, gas trapping and/or airway wall thickening), and abnormal spirometry - were evaluated in a group of 8784 current and former smokers who were participants in COPDGene® Phase 1. The GOLD2019 report, provided greater refinement of its ABCD paradigm by revisiting the utility of combining the ABCD classification scheme (symptoms and exacerbation frequency) with a separate scale for spirometry, Grades 1-4.2 For example, a patient with a forced expiratory volume in 1 second (FEV1) of 25%, a COPD Assessment Test (CAT) score of 25 and 2 exacerbations in the past 12 months would be a 4-D patient and triple therapy would be recommended, whereas a patient with an FEV1 of 30% but no exacerbations and a CAT score of 25 would be a 4-B and may warrant consideration for long-acting beta2-agonists/long-acting muscarinic antagonist (LABA/LAMA) without an inhaled corticosteroid (ICS) and could be considered for lung volume reduction or lung transplant due to severe emphysema and or significant small airway disease and air trapping.

This study demonstrates the utility of incorporating the 4 significant features of exposure, symptoms, CT scan characterization of emphysema and airway wall thickening and physiological measures of lung function. The COPD Genetic Epidemiology (COPDGene®) study includes over 10,000 current or former smokers in the United States enrolled between 2008 and 2011. Young KA, Strand M, Ragland MF, et al for the COPDGene Investigators. These high-risk participants fell into 3 groups: airway-predominant disease only (APD-only), emphysema-predominant disease only (EPD-only) and combined APD-EPD. COPD Chronic obstructive pulmonary disease . We propose to redefine the diagnosis of COPD through an integrated approach using environmental exposure, clinical symptoms, CT imaging and spirometric criteria. The COPDGene® articles presented in this Journal Club are thought-provoking and compelling yet there are a few important issues to put in perspective. The new year dawns with new guidelines.Global Initiative for Obstructive Lung Disease (GOLD 2020) has some major and few minor changes to offer for the management of COPD. To date, while oxygen therapy and smoking cessation have been shown to prolong survival, there are no medications that have been definitively proven to have the ability to improve survival or to change the natural course of the disease in ways that would be considered as disease modifying. Using smokers without symptoms, CT imaging abnormalities or airflow obstruction as the reference population, individuals were classified as Possible COPD, Probable COPD and Definite COPD. With this enormous database of exposure, symptoms, CT imaging, spirometry and biomarkers, the COPDGene® investigators set out to formulate a unique and new classification scheme for COPD patients by characterizing patients based on quantitative CT and physiologic and biomarker variables. COPDGene 2019: redefining the diagnosis of chronic obstructive pulmonary disease. As previously, group A patients start with short-acting bronchodilators, Group B with long-acting bronchodilators or the consideration of dual bronchodilators if they are particularly symptomatic. Also sobering is the fact that the combined airway predominant disease group and emphysema predominant disease group individuals progressed at the highest 5-year all-cause mortality. Benralizumab for the prevention of COPD exacerbations. Participants also complete 6- month interval telephone and web-based follow-ups. Blood eosinophils as a marker of response to inhaled corticosteroids in COPD. (GOLD 2020) has some major and few minor changes to offer for the management of COPD. Further, as we move forward, it is hoped that we will be able to discover new medications that may be truly disease modifying for patients with COPD. 2018;23(1):12-13. doi: https://doi.org/10.1111/resp.13200, 21. Criner GJ, Celli BR, Brightling CE, et al. The COPDGene® cohort is highly enriched with heavy smokers (average of approximately 50 pack years) with airflow limitation and therefore the findings, including associations and projections, may not be universally applicable to those with lower cigarette, (or biomass), exposure or non-smokers who demonstrate airflow limitation. Chronic obstructive pulmonary disease (COPD) remains a major cause of morbidity and mortality. of COPD (2020 Report), which aims to provide a non-biased review of the current evidence for the assessment, diagnosis and treatment of patients with COPD that can aid the clinician. With the IMPACT trial data16 bringing into question whether or not ICSs may indeed confer an improved survival benefit, we want to make sure we optimally characterize the spectrum of COPD patients to identify who are likely to benefit and whether such interventions have their greatest impact if they are started early. A substantial portion of smokers with respiratory symptoms and imaging abnormalities do not manifest spirometric obstruction as defined by population normals.

The MR-APD-only group was associated with conversion from GOLD 0 to preserved ratio-impaired spirometry (PRISm) status (odds ratio [OR] 11.3, 95% confidence interval [CI] 5.7-22.1) and GOLD 0 to GOLD 2-4 (OR 6.0, 95% CI 2.0-18.0). This marked the formation of a network of national leaders and the beginning of the Global initiative for chronic Obstructive Lung Disease (GOLD) reports.

Calverley PMA, Anzueto A, Carter K, et al. Baseline evaluations included pre-and post-bronchodilator spirometry, 6-minute walk test distance, inspiratory and expiratory computed tomography (CT) scans that included a quantitative assessment of airway wall thickness, emphysema and gas trapping.

The proposed COPDGene® 2019 diagnostic criteria would add an additional 3144 participants. The phosphodiesterase type 4 inhibitor roflumilast, and the macrolide antibiotic azithromycin have been added to help reduce the frequency of exacerbations. A new table has been added that provides a clearer outline of the decision factors to be used to decide on the use of ICSs and indicates that the strongest support is history of at least 1 hospitalization or at least 2 moderate exacerbations for COPD exacerbations or at least moderate exacerbations per year and blood eosinophil count > 300 cell/mcL and history of/or current concomitant asthma.

COPD Guidelines: The COPD-X plan Version 2.61, February 2020 Lung Foundation Australia’s COPD Guidelines Committee, manages the co-branded Lung Foundation and Thoracic Society of Australia and New Zealand’s, “The COPD-X Plan: Australian and New Zealand guidelines for the management of chronic obstructive pulmonary disease”. COPD affects millions of patients in the United States and exacerbations account for a significant proportion of healthcare expenditures each year. The study also highlights the need for such precision in understanding the underlying pathobiology as it is likely that targets for therapy will differ between those who have airway predominant disease only and those who have emphysema predominant disease only. Halpin DMG, Birk R, Brealey N, et al. The GOLD report continues to recommend initiating therapy only after patients demonstrate evidence of a threshold cutoff post-bronchodilator FEV1 to forced vital capacity (FVC) ratio of less than 70%. In the initial iterations of the GOLD guidelines such patients were considered to be GOLD 0 but this Grade was dropped in subsequent iterations of the GOLD report. 2018;81(1):13-18. doi: https://doi.org/10.4046/trd.2017.0098, 5.
