Abstract
AIMS To determine the lived experiences of people with COPD who isolated at home during the coronavirus disease 2019 (COVID-19) pandemic, and explore how these experiences affected health and patient-reported outcomes. METHODS Keyword searches were performed in five bibliographic databases. Critical interpretative synthesis (CIS) methods were used to interrogate and understand patterns across studies. RESULTS 23 studies were identified; three employed qualitative methods and 20 quantitative methods. Application of CIS methods highlighted a core synthetic concept that appeared to underpin experiences and outcomes, that of a heightened perception of risk. Using the Risk Perception Model as a framework, we found that cognitive factors such as knowledge of underlying health status and the transmissibility of COVID-19; experiential factors including previous episodes of breathlessness and hospitalisation; and sociocultural factors such as access to trusted sources of information, influenced perceptions of risk. In turn, this influenced behaviour, which translated to outcomes such as reduced hospitalisations, deconditioning and social isolation as people avoided "high-risk" situations and settings. CONCLUSIONS Patients with COPD who isolated at home during the COVID-19 pandemic had a heightened perception of risk which was influenced by cognitive, experiential and sociocultural factors. The consequences of this were varied and included both positive (reduced exacerbations and hospitalisations) and negative (social isolation, deconditioning, diminished capacity for self-care) outcomes. Understanding risk and the impacts it can have could help clinicians to support people with COPD return to their pre-pandemic way of living and enable better communication of ongoing risk from respiratory viral illness.

Abstract
Chronic obstructive pulmonary disease (COPD) is significant cause of morbidity and mortality worldwide. There is mounting evidence suggesting that COPD patients are at increased risk of severe COVID-19 outcomes; however, it remains unclear whether they are more susceptible to acquiring SARS-CoV-2 infection. In this comprehensive review, we aim to provide an up-to-date perspective of the intricate relationship between COPD and COVID-19. We conducted a thorough review of the literature to examine the evidence regarding the susceptibility of COPD patients to COVID-19 infection and the severity of their disease outcomes. While most studies have found that pre-existing COPD is associated with worse COVID-19 outcomes, some have yielded conflicting results. We also discuss confounding factors such as cigarette smoking, inhaled corticosteroids, and socioeconomic and genetic factors that may influence this association. Furthermore, we review acute COVID-19 management, treatment, rehabilitation, and recovery in COPD patients and how public health measures impact their care. In conclusion, while the association between COPD and COVID-19 is complex and requires further investigation, this review highlights the need for careful management of COPD patients during the pandemic to minimize the risk of severe COVID-19 outcomes.

Real-World COPD Management Over 3 Years at the Community Health Service Center of Shanghai During the COVID-19 Pandemic in China. Int J Chron Obstruct Pulmon Dis 2023; 18:349-364. [PMID: 36960355 PMCID: PMC10029936 DOI: 10.2147/copd.s391908] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2022] [Accepted: 03/06/2023] [Indexed: 03/19/2023] Open
Abstract
Objective To evaluate the real-world situation for the management of chronic obstructive pulmonary disease (COPD) and poorly controlled disease risk factors in the Chinese community. Methods This retrospective multicentre study analysed data from COPDMICand MICHC in Shanghai Songjiang District, Shanghai, China. The differences in COPD Assessment Test (CAT), the modified Medical Research Council (mMRC) dyspnea scale, and the number of emergency cases, emergency visits, inpatient cases, and hospitalisations from January 2018 to December 2020 were analysed. The impact of coronavirus disease 2019 (COVID-19) on COPD management was also assessed. Results For 2020 versus 2018, analysis of 468 COPD cases from COPDMIC matched with MICHC data showed significantly more patients with improved mMRC grades, significantly fewer emergency cases and emergency visits, and significantly fewer hospitalisation cases and hospitalisations. Differences in the number of emergency visits and hospitalisations per capita were statistically significant. Compared to GOLD 3-4, GOLD 1-2 patients showed significant improvements in CAT score, mMRC grade, the number of emergency visits and hospitalisations per capita. Treatment adherence from 2018 to 2020 was 25%, 29.1%, and 6.8%, and the proportion of medication regimens consistent with guidelines was 43.44%, 50.98%, and 71.87%, respectively. Higher treatment adherence resulted in significantly improved CAT scores and mMRC grades and fewer emergency department visits and hospitalisations per capita. Conclusion Combined with remote management tools, patients with COPD achieved continuous improvement in symptoms and exacerbations over 3 years. In the context of COVID-19 prevention/control measures, improvements were significant for patients with GOLD 1-2 COPD but limited with GOLD 3-4. Pharmacologic treatment significantly improved clinical symptoms and reduced emergency visits and hospitalisations. Severe airflow limitation and poor adherence to pharmacologic treatment were important risk factors for lack of disease remission.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel coronavirus that causes an acute respiratory tract infection known as coronavirus disease 2019 (COVID-19). SARS-CoV-2 enters cells by binding the ACE2 receptor and coreceptors notably TMPRSS2 or Cathepsin L. Severe COVID-19 infection can lead to acute lung injury. Below we describe the current evidence of the impact of common chronic lung diseases (CLDs) on the development of COVID-19. The impact of treatment of CLD on COVID-19 and any risk of vaccination in patients with CLD are considered.

Abstract
Objective: To analyze all chronic obstructive pulmonary disease (COPD) drugs-related articles that were indexed in the Web of Science Core Collection (WOSCC) database until August 28, 2021 using bibliometric analysis, in order to provide a reliable reference for the treatment of COPD. Methods: A comprehensive search was conducted to analyze all COPD drugs-related articles using WOSCC database from inception to August 28, 2021. Abstracts and potentially eligible articles, which were retrieved during literature search, were screened by two reviewers. Besides, the CiteSpace (5.8.R1) software was utilized to analyze the overall structure of the network, the network clusters, the links between clusters, the key nodes or pivot points, and the pathways. Results: A total of 2552 COPD-drugs related articles were retrieved. From the perspective of categorization of published articles based on country, the United States is the country with the largest number of published articles and completed clinical trials, highlighting the important role of this country in the treatment of COPD. However, in terms of the proportion of ongoing clinical trials, China has the highest proportion, suggesting that China will play a more pivotal role in the medication of COPD in the future. From the perspective of cooperation among countries, the cooperation among European countries was closer than that among Asian countries. In the recent three decades, the top 20 institutions, with a particular concentration on the treatment of COPD, were from North America and Europe. The co-citation analysis showed that, among 2,552 articles, 53154 citations were recorded, and the co-citation network indicated that 24 clusters could be achieved. Conclusion: The administration of bronchodilators and pulmonary drug delivery systems, as well as consideration of elderly COPD patients remained the hotspots, while triple therapy and comorbidity of COPD, as well as the prevention and treatment of elderly COPD patients had been frontiers in recent years.

Abstract
OBJECTIVE The objective of this study is to analyze chronic obstructive pulmonary disease exacerbation rates and the effect of patients' behavioral changes on the exacerbations during the pandemic. MATERIAL AND METHODS This study was conducted in a reference hospital for chest diseases and patients who were hospitalized with an exacerbation of chronic obstructive pulmonary disease between March 11, 2019, and March 11, 2020, were designated. Patients' chronic obstructive pulmonary disease exacerbations requiring emergency department visits and/or hospitalization were com- pared between the pre-pandemic and pandemic periods. Each patient was surveyed with 25 questions using telemedicine. RESULTS Of all the 256 patients, 203 (79%) were male and the mean age was 66 ± 10 years. Compared to the previous year, emer- gency department visits and hospitalizations in our hospital were significantly lower and less frequent (P < .0001, for both). Smoking habits decreased in 9% of patients, and 60% had hardly spent time outdoors. Only 3 patients reported to spend time indoors. The household mask-use rate while contacting the patient was 50%. As a chronic obstructive pulmonary disease patient, 33% expressed themselves as "feeling better." Overall, 92(36%) patients were recorded not to have any exacerbation, and 34 (13%) to have no attacks of worsening were managed at home. Novel exacerbation risk was found to independently correlate with younger age (odds ratio: 0.944, CI: 0.904-0.986, P = .010) and having more frequent episodes of exacerbation in the pre-pandemic period (odds ratio: 1.2, CI: 1.025-1.405, P = .023). CONCLUSION Chronic obstructive pulmonary disease patients specifically benefited from confinements, restrictions, and lifestyle changes. Further studies are needed to better identify the most critical factors leading to these positive outcomes. A permanent patient management guideline for chronic obstructive pulmonary disease patients could be formulated where the weight of lifestyle factors is elevated.

Abstract
Objectives: The coronavirus-19 (COVID-19) pandemic has claimed more than 5 million lives worldwide by November 2021. Implementation of lockdown measures, reallocation of medical resources, compounded by the reluctance to seek help, makes it exceptionally challenging for people with non-communicable diseases (NCD) to manage their diseases. This review evaluates the spill-over impact of the COVID-19 pandemic on people with NCDs including cardiovascular diseases, cancer, diabetes mellitus, chronic respiratory disease, chronic kidney disease, dementia, mental health disorders, and musculoskeletal disorders.Methods: Literature published in English was identified from PubMed and medRxiv from January 1, 2019 to November 30, 2020. A total of 119 articles were selected from 6,546 publications found.Results: The reduction of in-person care, screening procedures, delays in diagnosis, treatment, and social distancing policies have unanimously led to undesirable impacts on both physical and psychological health of NCD patients. This is projected to contribute to more excess deaths in the future.Conclusion: The spill-over impact of COVID-19 on patients with NCD is just beginning to unravel, extra efforts must be taken for planning the resumption of NCD healthcare services post-pandemic.

Abstract
BACKGROUND Studies have shown a decline in hospitalizations due to acute exacerbations of COPD (AECOPD) during the coronavirus disease 2019 (COVID-19) pandemic. However, the impact of the pandemic in AECOPD of all severities in longitudinal cohorts of patients is lacking. METHODS We conducted analysis of 123 individuals with COPD who have been followed since 2017. AECOPDs of mild (treatment at home), moderate (emergency department or urgent visit evaluation), and severe (hospitalization) type were assessed by chart review and patient interview. Compliance with preventive measures to avoid COVID-19 infection was assessed in 2020. Differences between the rate of AECOPD by year was analyzed as well as differences in preventive measures by COPD disease severity. RESULTS During the COVID-19 pandemic in 2020, there was a significant reduction in AECOPDs in our cohort with 26 participants (21%) having an exacerbation compared to 46 (37%) in 2019, 52 (42%) in 2018, and 44 (36%) in 2017. Mean exacerbation rates decreased 54% overall and 74% in frequent exacerbators compared with the prior 3-year average. The decrease was noted in AECOPDs of all severities. Overall, there was a high rate of reported compliance with social distancing and face mask use that was significantly higher in the group with more severe COPD based on symptoms and forced expiratory volume in 1 second. CONCLUSIONS Individuals with COPD, including frequent exacerbators, showed a marked decrease in AECOPD during the COVID-19 pandemic and high adherence to recommended preventive measures. Evaluation of the impact of preventive strategies on AECOPD in a non-pandemic setting may be of value and requires further study.

Abstract
OBJECTIVES We conducted a systematic literature review and meta-analysis of observational studies to investigate the association between diabetes, hypertension, body mass index (BMI) or smoking with the risk of death in patients with COVID-19 and to estimate the proportion of deaths attributable to these conditions. METHODS Relevant observational studies were identified by searches in the PubMed, Cochrane library and Embase databases through 14 November 2020. Random-effects models were used to estimate summary relative risks (SRRs) and 95% CIs. Certainty of evidence was assessed using the Cochrane methods and the Grading of Recommendations, Assessment, Development and Evaluations framework. RESULTS A total of 186 studies representing 210 447 deaths among 1 304 587 patients with COVID-19 were included in this analysis. The SRR for death in patients with COVID-19 was 1.54 (95% CI 1.44 to 1.64, I2=92%, n=145, low certainty) for diabetes and 1.42 (95% CI 1.30 to 1.54, I2=90%, n=127, low certainty) for hypertension compared with patients without each of these comorbidities. Regarding obesity, the SSR was 1.45 (95% CI 1.31 to 1.61, I2=91%, n=54, high certainty) for patients with BMI ≥30 kg/m2 compared with those with BMI <30 kg/m2 and 1.12 (95% CI 1.07 to 1.17, I2=68%, n=25) per 5 kg/m2 increase in BMI. There was evidence of a J-shaped non-linear dose-response relationship between BMI and mortality from COVID-19, with the nadir of the curve at a BMI of around 22-24, and a 1.5-2-fold increase in COVID-19 mortality with extreme obesity (BMI of 40-45). The SRR was 1.28 (95% CI 1.17 to 1.40, I2=74%, n=28, low certainty) for ever, 1.29 (95% CI 1.03 to 1.62, I2=84%, n=19) for current and 1.25 (95% CI 1.11 to 1.42, I2=75%, n=14) for former smokers compared with never smokers. The absolute risk of COVID-19 death was increased by 14%, 11%, 12% and 7% for diabetes, hypertension, obesity and smoking, respectively. The proportion of deaths attributable to diabetes, hypertension, obesity and smoking was 8%, 7%, 11% and 2%, respectively. CONCLUSION Our findings suggest that diabetes, hypertension, obesity and smoking were associated with higher COVID-19 mortality, contributing to nearly 30% of COVID-19 deaths.

[PMID: 34568353 PMCID: PMC8455871 DOI: 10.3389/fmed.2021.663514] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Accepted: 06/30/2021] [Indexed: 01/08/2023] Open
Abstract
Objective: To assess CT features of COVID-19 patients with different smoking status using quantitative and semi-quantitative technologies and to investigate changes of CT features in different disease states between the two groups. Methods: 30 COVID-19 patients with current smoking status (29 men, 1 woman) admitted in our database were enrolled as smoking group and 56 COVID-19 patients without smoking history (24 men, 32 women) admitted during the same period were enrolled as a control group. Twenty-seven smoking cases and 55 control cases reached recovery standard and were discharged. Initial and follow-up CT during hospitalization and follow-up CT after discharge were acquired. Thirty quantitative features, including the ratio of infection volume and visual-assessed interstitial changes score including total score, score of ground glass opacity, consolidation, septal thickening, reticulation and honeycombing sign, were analyzed. Results: Initial CT images of the smoking group showed higher scores of septal thickening [4.5 (0–5) vs. 0 (0–4), p = 0.001] and reticulation [0 (0–5.25) vs 0 (0–0), p = 0.001] as well as higher total score [7 (5–12.25) vs. 6 (5–7), p = 0.008] with statistical significance than in the control group. The score of reticulation was higher in the smoking group than in the control group when discharged [0.89 (0–0) vs. 0.09 (0–0), p = 0.02]. The score of septal thickening tended to be higher in the smoking group than the control group [4 (0–4) vs. 0 (0–4), p = 0.007] after being discharged. Quantitative CT features including infection ratio of whole lung and left lung as well as infection ratio within HU (−750, −300) and within HU (−300, 49) were higher in the control group of initial CT with statistical differences. The infection ratio of whole lung and left lung, infection ratio within HU (−750), and within HU (−750, −300) were higher in the control group with statistical differences when discharged. This trend turned adverse after discharge and the values of quantitative features were generally higher in the smoking group than in the control group without statistical differences. Conclusions: Patients with a history of smoking presented more severe interstitial manifestations and more residual lesion after being discharged. More support should be given for COVID-19 patients with a smoking history during hospitalization and after discharge.

PLoS One 2021; 16:e0255659. [PMID: 34343205 PMCID: PMC8330941 DOI: 10.1371/journal.pone.0255659] [Citation(s) in RCA: 82] [Impact Index Per Article: 27.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2021] [Accepted: 07/21/2021] [Indexed: 01/28/2023] Open
Abstract
BACKGROUND Reports have suggested a reduction in exacerbations of chronic obstructive pulmonary disease (COPD) during the coronavirus disease 2019 (COVID-19) pandemic, particularly hospital admissions for severe exacerbations. However, the magnitude of this reduction varies between studies. METHOD Electronic databases were searched from January 2020 to May 2021. Two independent reviewers screened titles and abstracts and, when necessary, full text to determine if studies met inclusion criteria. A modified version of the Newcastle-Ottawa Scale was used to assess study quality. A narrative summary of eligible studies was synthesised, and meta-analysis was conducted using a random effect model to pool the rate ratio and 95% confidence intervals (95% CI) for hospital admissions. Exacerbation reduction was compared against the COVID-19 Containment and Health Index. RESULTS A total of 13 of 745 studies met the inclusion criteria and were included in this review, with data from nine countries. Nine studies could be included in the meta-analysis. The pooled rate ratio of hospital admissions for COPD exacerbations during the pandemic period was 0.50 (95% CI 0.44-0.57). Findings on the rate of community-treated exacerbations were inconclusive. Three studies reported a significant decrease in the incidence of respiratory viral infections compared with the pre-pandemic period. There was not a significant relationship between exacerbation reduction and the COVID-19 Containment and Health Index (rho = 0.20, p = 0.53). CONCLUSION There was a 50% reduction in admissions for COPD exacerbations during the COVID-19 pandemic period compared to pre-pandemic times, likely associated with a reduction in respiratory viral infections that trigger exacerbations. Future guidelines should consider including recommendations on respiratory virus infection control measures to reduce the burden of COPD exacerbations beyond the pandemic period.

The Risk of COVID-19 Related Hospitalsation, Intensive Care Unit Admission and Mortality in People With Underlying Asthma or COPD: A Systematic Review and Meta-Analysis. Front Med (Lausanne) 2021; 8:668808. [PMID: 34222281 PMCID: PMC8242585 DOI: 10.3389/fmed.2021.668808] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2021] [Accepted: 05/17/2021] [Indexed: 12/13/2022] Open
Abstract
Background: Several underlying diseases have been associated with unfavorable COVID-19 related outcomes including asthma and Chronic Obstructive Pulmonary Disease (COPD), however few studies have reported risks that are adjusted for confounding variables. This study aimed to examine the adjusted risk of COVID-19 related hospitalsation, intensive care unit (ICU) admission, and mortality in patients with vs. without asthma or COPD. Methods: A systematic review of major databases was undertaken for studies published between 1/12/2019 and 19/4/2021. Studies reporting the adjusted (for one or more confounder) risks of either hospitalsation, ICU admission, or mortality in asthmatics or COPD patients (control group = no asthma or no COPD) were identified. Risk of bias was determined via the QUIPS tool. A random effect meta-analysis was undertaken. Findings: 37 studies were eligible for analysis, with a total of 1,678,992 participants. The pooled ORs of COVID-19 hospitalsation in subjects with asthma and COPD was 0.91 (95% CI 0.76-1.09) and 1.37 (95% CI 1.29-1.46), respectively. For ICU admission, OR in subjects with asthma and COPD was 0.89 (95% CI 0.74-1.07) and 1.22 (95% CI 1.04-1.42), respectively. For mortality, ORs were 0.88 (95% CI 0.77-1.01) and 1.25 (95% CI 1.08-1.34) for asthma and COPD, respectively. Further, the pooled risk of mortality as measured via Cox regression was 0.93 (95% CI 0.87-1.00) for asthma and 1.30 (95% CI 1.17-1.44) for COPD. All of these findings were of a moderate level of certainty. Interpretation: COPD was significantly associated with COVID-19 related hospital admission, ICU admission, and mortality. Asthma was not associated with negative COVID-19 related health outcomes. Individuals with COPD should take precautions to limit the risk of COVID-19 exposure to negate these potential outcomes. Limitations include differing population types and adjustment for differing cofounding variables. Practitioners should note these findings when dealing with patients with these comorbidities.

Abstract
Introduction: The role of COPD in COVID-19 is not yet well understood. However, there is increasing evidence showing that COPD patients with COVID-19 have a higher risk of presenting a serious infection, a greater likelihood of requiring ICU support, and a higher mortality than other groups.Areas covered: In this article, we address some critical questions on COVID-19 as they pertain to COPD. In particular, we discuss whether the usual algorithms of pharmacological and non-pharmacological management in COPD still apply.Expert opinion: Patients with COPD must continue their regular therapy, regardless of whether they are affected by COVID-19. Corticosteroids reduce mortality in COVID-19 patients in need of supportive oxygen therapy or invasive mechanical ventilation. It is essential that a COPD patient who has tested positive for SARS-CoV-2 is closely followed over time because any delay in diagnosis and initiation of appropriate therapy could negatively affect his/her prognosis. However, we still do not know if COVID-19 infection occurs and evolves differently in each of the recognized COPD phenotypes and, therefore, whether it needs a different management. There are other open questions concerning COVID-19 and COPD that need to be considered. Future studies are absolutely necessary to answer these questions.

Impact of COVID-19 lockdown on the incidence and mortality of acute exacerbations of chronic obstructive pulmonary disease: national interrupted time series analyses for Scotland and Wales. BMC Med 2021; 19:124. [PMID: 33993870 PMCID: PMC8126470 DOI: 10.1186/s12916-021-02000-w] [Citation(s) in RCA: 36] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Accepted: 04/30/2021] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND The COVID-19 pandemic and ensuing national lockdowns have dramatically changed the healthcare landscape. The pandemic's impact on people with chronic obstructive pulmonary disease (COPD) remains poorly understood. We hypothesised that the UK-wide lockdown restrictions were associated with reductions in severe COPD exacerbations. We provide the first national level analyses of the impact of the COVID-19 pandemic and first lockdown on severe COPD exacerbations resulting in emergency hospital admissions and/or leading to death as well as those recorded in primary care or emergency departments. METHODS Using data from Public Health Scotland and the Secure Anonymised Information Linkage Databank in Wales, we accessed weekly counts of emergency hospital admissions and deaths due to COPD over the first 30 weeks of 2020 and compared these to the national averages over the preceding 5 years. For both Scotland and Wales, we undertook interrupted time-series analyses to model the impact of instigating lockdown on these outcomes. Using fixed-effect meta-analysis, we derived pooled estimates of the overall changes in trends across the two nations. RESULTS Lockdown was associated with 48% pooled reduction in emergency admissions for COPD in both countries (incidence rate ratio, IRR 0.52, 95% CI 0.46 to 0.58), relative to the 5-year averages. There was no statistically significant change in deaths due to COPD (pooled IRR 1.08, 95% CI 0.87 to 1.33). In Wales, lockdown was associated with 39% reduction in primary care consultations for acute exacerbation of COPD (IRR 0.61, 95% CI 0.52 to 0.71) and 46% reduction in COPD-related emergency department attendances (IRR 0.54, 95% CI 0.36 to 0.81). CONCLUSIONS The UK-wide lockdown was associated with the most substantial reductions in COPD exacerbations ever seen across Scotland and Wales, with no corresponding increase in COPD deaths. This may have resulted from reduced transmission of respiratory infections, reduced exposure to outdoor air pollution and/or improved COPD self-management.

Abstract
In people recovering from COVID-19, there is concern regarding potential long-term pulmonary sequelae and associated impairment of functional capacity. Data published thus far indicate that spirometric indices appear to be generally well preserved, but that a defect in diffusing capacity (DLco) is a prevalent abnormality identified on follow-up lung function; present in 20-30% of those with mild to moderate disease and 60% in those with severe disease. Reductions in total lung capacity were commonly reported. Functional capacity is also often impaired, with data now starting to emerge detailing walk test and cardiopulmonary exercise test outcome at follow-up. In this review, we evaluate the published evidence in this area, to summarise the impact of COVID-19 infection on pulmonary function and relate this to the clinico-radiological findings and disease severity.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has affected millions of people worldwide, and pneumonia affects 90% of patients. This raises the possibility of millions of people with altered lung function. Few data exist to date on pulmonary function after SARS-CoV-2 infection, but alteration of diffusion capacity of CO (D LCO) is the most frequently described abnormality. First, we present original data on lung function at 3 months after SARS-CoV-2 infection and discuss the effect of using European Coal and Steel Community (ECSC) or Global Lung Function Initiative (GLI) reference equations to diagnose diffusion capacity. Second, we review existing data on D LCO alteration after SARS-CoV-2 infection and discuss the implication of restrictive disorder in D LCO alteration. Last, we discuss the pathophysiology of D LCO alteration and try to disentangle vascular damage and fibrosis.

Abstract
Viral infections are known to be the main trigger for Chronic obstructive pulmonary disease (COPD) exacerbations. Face masks are acknowledged for effective viral aerosol shedding reduction. COVID-19 pandemic generated an opportunity to study the impact of face masks and confinement on droplet transmission diseases, usually implicated in acute exacerbations of COPD (AECOPD). We aimed to evaluate the variation on severe AECOPD (sAECOPD) rate in a Portuguese COPD cohort during the first COVID-19 lockdown and following months. This retrospective self-controlled study enrolled 322 adult patients followed at COPD-specialized consultation in a tertiary hospital from February 2016 to July 2020, of whom 286 met inclusion criteria. Severe AECOPD events were registered from March 2020 (beginning of state of emergency) until July 2020. From 2016 to 2019 there was a mean of 38 patients per year with sAECOPD. During 2020, 11 patients experienced sAECOPD. Over the course of 2020 there was a 73.4% (p < 0.001) decrease in sAECOPD events comparing with previous years' average. After the end of State of Emergency, the rate of sAECOPD events also declined by 74.6% (p < 0.001) comparing with the same timeline of previous years. Results were consistent and statistically significant when comparing 2020 with each of previous years for every period of analysis. Our findings suggest a sustained decrease in the rate of sAECOPD during confinement and in the following months. The widespread use of face mask and social distancing during COVID-19 pandemic may play an important role in preventing the transmission of respiratory infections and consequently reducing sAECOPD.
