“… 25 In this systematic review, we included the data of ECLIPSE, and the data about COPD or smoking population from the COPDGene and FHS in the study by Putman et al 13 The data of the other cohort were excluded because the COPD/emphysema subpopulation was not defined. Studies by Washko et al 7 Ash et al 17 and Menon et al 27 analyzed the COPDGene cohort. We included these 3 studies in this systematic review because Ash et al 17 and Menon et al 27 investigated the impact of ILAs on individuals with emphysema, and Washko et al 7 examined the interaction between ILAs and COPD/emphysema.…”

Background Both COPD and interstitial lung abnormalities (ILAs) are conditions associated with smoking and age. The impact of coexistent ILAs on the manifestations and outcomes of COPD or emphysema awaits evaluation. Methods We searched PubMed and Embase using Medical Subject Headings terms in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results Eleven studies were included in the review. The sample size of the studies ranged from 30 to 9579. ILAs were reported in 6.5% to 25.7% of the patients with COPD/emphysema, higher than that reported in the general populations. COPD/emphysema patients with ILAs were older, mostly male, and had a higher smoking index than those without ILAs. Hospital admission and mortality were increased in COPD patients with ILAs compared to those without ILAs, whereas the frequency of COPD exacerbations was discrepant in 2 of the studies. The FEV 1 and FEV 1 % predicted tended to be higher in the group with ILAs, but not significantly in most of the studies. Conclusion ILAs were more frequent in subjects with COPD/emphysema than in the general population. ILAs may have a negative impact on hospital admission and mortality of COPD/emphysema. The impact of ILAs on lung functions and exacerbations of COPD/emphysema was discrepant in these studies. Further prospective studies are warranted to provide high-quality evidence of the association and interaction between COPD/emphysema and ILAs.
