We aimed to evaluate the clinical characteristics of COPD-related hospital admissions and mortality in relation to the presence of COVID-19.Patients and Methods: We conducted a case–control study of patients admitted in four teaching hospitals throughout Spain between March 15 and April 30, 2020. Hospital admissions of respiratory cause with and without PCR-proven SARS-CoV-2 infection in patients with COPD were evaluated. Baseline and episode-related clinical characteristics were analyzed. Logistic regression analysis was performed to evaluate the risk for mortality.Results: During the study period, 2101 patients were admitted for respiratory worsening, 1200 (57.1%) with COVID-19. A total of 228 (10.8%) were admitted due to COPD worsening, of whom 52 (22.8%) tested positive for COVID-19. COPD patients with COVID-19, when compared to those without COVID-19, were more frequently males with better lung function (FEV1 postbronchodilator 71% vs 46% respectively, p< 0.001) and had higher mortality (44.9% vs 13.6% respectively, p< 0.001) despite similar age, comorbidities, total days of hospitalization and admission to intensive care unit. COVID-19 and eosinopenia were the strongest risk factors for mortality in the multivariate analysis in the overall COPD population. Inhaled corticosteroid use was not associated to mortality.Conclusion: Hospitalizations for ECOPD without COVID-19 were more frequent than COPD with COVID-19 during the first outbreak, but the latter were associated with higher mortality and low eosinophil counts that warrant further analysis.Keywords: COPD exacerbation, mortality, inhaled corticosteroids, hospitalization

Twelve patients were subjected to TBCB and 13 to forceps transbronchial lung biopsy (TBLB).Results: The diagnostic yield was significantly higher among the TBCB group (83.3%), and increased to 100% with clinicopathological correlation vs the TBLB group (38.5%, P=0.041). Granulomatous diseases (24%, either sarcoidosis or hypersensitivity pneumonitis) were the commonest pathology, followed by malignancy (12%) in both groups. TBCB sizes were 2.5–5 mm vs 1-3 mm in TBLB (P

Image-enhanced bronchoscopy may offer a less invasive method for studying bronchial microvasculature in COPD. Objectives: To evaluate endobronchial mucosal vasculature and changes in COPD by image-enhanced i-scan3 bronchoscopy and correlate them pathologically by analyzing bronchial mucosal biopsies. Methods: This case–control study analyzed 29 COPD patients (41.4% Global initiative for chronic Obstructive Lung Disease B [GOLD B] and 58.6% GOLD D) and ten healthy controls admitted at Alexandria Main University Hospital, Egypt. Combined high-definition white light bronchoscopy (HD WLB) with i-scan3 was used to evaluate endobronchial mucosal microvasculature. The vascularity was graded according to the level of mucosal red discoloration (ie, endobronchial erythema) from decreased discoloration to normal, mild, moderate, and severe increased red discoloration (G-1, G0, G+1, G+2, and G+3, respectively) and scored by three bronchoscopists independently. Bronchial mucosal biopsies were taken for microvascular density counting using anti-CD34 antibody as angiogenesis marker. Results: Different grades of endobronchial erythema were observed across/within COPD patients using combined HD WLB + i-scan3, with significant agreement among scorers (P=0.031; median score of G+1 [G-1–G+2]) being higher in GOLD D (P=0.001). Endobronchial erythema significantly correlated with COPD duration, exacerbation frequency, and body mass index (P

Endobronchial erythema significantly correlated with COPD duration, exacerbation frequency, and body mass index ( P <0.05). Angiogenesis was significantly decreased among COPD patients versus controls (10.6 [8-13.3] vs 14 [11-17.1]; P =0.02). Mucosal surface changes (including edema, atrophy, and nodules) were better visualized by the combined HD WLB + i-scan3 rather than HD WLB alone., Conclusion: Combined HD WLB + i-scan3 seems to be valuable in evaluating mucosal microvasculature and surface changes in COPD, which may represent vasodilatation rather than angiogenesis.
