Abstract
INTRODUCTION COPD is a leading cause of global mortality, particularly under-recognized and under-diagnosed. In 2020, it was the sixth leading cause of death in the US and has contributed to 4.72% of all-cause mortality (ACM) according to the Global Burden of Disease Study 2017. Factors influencing COPD-related mortality include smoking, aging populations, comorbidities, sarcopenia, physical capacity, and lack of effective treatments. AREAS COVERED This review discusses various factors influencing COPD-related mortality and analyzes observational studies and pivotal RCTs evaluating the impact of different therapies on ACM. EXPERT OPINION COPD significantly impacts ACM, necessitating effective management strategies. Smoking cessation is crucial in reducing mortality risk. Exacerbation management and comorbidity treatment are essential to improve patient outcomes. Various therapeutic interventions, such as smoking cessation, vaccination, long-term oxygen therapy, and lung volume reduction surgery, have shown benefits in reducing mortality. Pharmacotherapies might reduce the risk of mortality, although the current scientific evidences remain inconclusive. Advances in pharmacological interventions, tailored treatment plans, and physical activity programs are vital. More robust and long-term studies, focusing on real-world data and addressing biases in treatment allocation, are needed to conclusively determine the efficacy of different therapies in reducing ACM in COPD patients.

BMJ Open Respir Res 2024; 11:e001964. [PMID: 39304207 PMCID: PMC11418573 DOI: 10.1136/bmjresp-2023-001964] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Accepted: 09/03/2024] [Indexed: 09/22/2024] Open
Abstract
BACKGROUND Assessing medication adherence is crucial in chronic obstructive pulmonary disease (COPD) management to prevent exacerbations. However, it is unclear whether this association between adherence and exacerbations is influenced by the adherence assessment methods or thresholds used. Electronic healthcare databases are valuable to study exacerbations and adherence in real life. We aimed to systematically review the literature to identify adherence assessment methods and thresholds used in healthcare databases when investigating the association between medication adherence and COPD exacerbations and to meta-analyse the associated effect sizes. METHOD MEDLINE, Web of Science and Embase were searched for peer-reviewed articles, written in English, published up to 10 October 2022 (PROSPERO: CRD42022363449). Two reviewers independently conducted screening for inclusion and performed data extraction. A qualitative approach described the adherence assessment methods and thresholds used. A quantitative approach (meta-analysis using random effects model) estimated the association between adherence and the risk of COPD exacerbations. RESULTS Eight studies were included in the systematic review of which five studies were included in the meta-analysis. The medication possession ratio (MPR) and the proportion of days covered (PDC) were the adherence assessment methods used and 0.80 was always used as threshold to differentiate good from poor adherence. Adherence and exacerbations were mostly measured over the same time period. Poor adherence (MPR or PDC<0.80) was significantly associated with a higher COPD exacerbation risk (OR 1.40, 95% CI 1.21 to 1.62, I2=85%), regardless of the adherence assessment method used. Results were consistent when stratified by exacerbation severity. Poor adherence was also associated with a time-dependent risk of COPD exacerbations (incidence rate ratio 1.31, 95% CI 1.17 to 1.46). CONCLUSION Our systematic review with meta-analysis demonstrated a 40% increased risk of COPD exacerbations in case of poor adherence to inhaler medication.

Abstract
BACKGROUND The management of chronic obstructive pulmonary disease (COPD) lacks standardization due to the diverse clinical presentation, comorbidities, and limited acceptance of recommended approaches by physicians. To address this, a multicenter study was conducted among Italian respiratory physicians to assess consensus on COPD management and pharmacological treatment. METHODS The study employed the Delphi process using the Estimate-Talk-Estimate method, involving a scientific board and expert panel. During a 6-month period, the scientific board conducted the first Delphi round and identified 11 broad areas of COPD management to be evaluated while the second Delphi round translated all 11 items into statements. The statements were subsequently presented to the expert panel for independent rating on a nine-point scale. Consensus was considered achieved if the median score was 7 or higher. Consistently high levels of consensus were observed in the first rating, allowing the scientific board to finalize the statements without requiring further rounds. RESULTS Topics generating substantial discussion included the pre-COPD phase, patient-reported outcomes, direct escalation from a single bronchodilator to triple therapy, and the role of adverse events, particularly pneumonia, in guiding triple therapy prescriptions. Notably, these topics exhibited higher standard deviations, indicating greater variation in expert opinions. CONCLUSIONS The study emphasized the significance that Italian pulmonologists attribute to managing mortality, tailoring treatments, and addressing cardiovascular comorbidities in COPD patients. While unanimous consensus was not achieved for all statements, the results provide valuable insights to inform clinical decision-making among physicians and contribute to a better understanding of COPD management practices in Italy.

The Potential Use and Value of a Wearable Monitoring Bracelet for Patients With Chronic Obstructive Pulmonary Disease: Qualitative Study Investigating the Patient and Health Care Professional Perspectives. JMIR Form Res 2024; 8:e57108. [PMID: 39270210 DOI: 10.2196/57108] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2024] [Revised: 06/06/2024] [Accepted: 06/26/2024] [Indexed: 09/15/2024] Open
Abstract
BACKGROUND The occurrence of exacerbations has major effects on the health of people with chronic obstructive pulmonary disease (COPD). Monitoring devices that measure (vital) parameters hold promise for timely identification and treatment of exacerbations. Stakeholders' perspectives on the use of monitoring devices are of importance for the successful development and implementation of a device. OBJECTIVE This study aimed to explore the potential use and value of a wearable monitoring bracelet (MB) for patients with COPD at high risk for exacerbation. The perspectives of health care professionals as well as patients were examined, both immediately after hospitalization and over a longer period. Furthermore, potential facilitators and barriers to the use and implementation of an MB were explored. METHODS Data for this qualitative study were collected from January to April 2023. A total of 11 participants (eg, n=6 health care professionals [HCPs], 2 patients, and 3 additional patients) participated. In total, 2 semistructured focus groups were conducted via video calls; 1 with HCPs of various professional backgrounds and 1 with patients. In addition, 3 semistructured individual interviews were held with patients. The interviews and focus groups addressed attitudes, wishes, needs, as well as factors that could either support or impede the potential MB use. Data from interviews and focus groups were coded and analyzed according to the principles of the framework method. RESULTS HCPs and patients both predominantly emphasized the importance of an MB in terms of promptly identifying exacerbations by detecting deviations from normal (vital) parameters, and subsequently alerting users. According to HCPs, this is how an MB should support the self-management of patients. Most participants did not anticipate major differences in value and use of an MB between the short-term and the long-term periods after hospitalization. Facilitators of the potential use and implementation of an MB that participants highlighted were ease of use and some form of support for patients in using an MB and interpreting the data. HCPs as well as patients expressed concerns about potential costs as a barrier to use and implementation. Another barrier that HCPs mentioned, was the prerequisite of digital literacy for patients to be able to interpret and react to the data from an MB. CONCLUSIONS HCPs and patients both recognize that an MB could be beneficial and valuable to patients with COPD at high risk for exacerbation, in the short as well as the long term. In particular, they perceived value in supporting self-management of patients with COPD. Stakeholders would be able to use the obtained insights in support of the effective implementation of MBs in COPD patient care, which can potentially improve health care and the overall well-being of patients with COPD.

Remote Patient Monitoring and Machine Learning in Acute Exacerbations of Chronic Obstructive Pulmonary Disease: Dual Systematic Literature Review and Narrative Synthesis. J Med Internet Res 2024; 26:e52143. [PMID: 39250789 PMCID: PMC11420610 DOI: 10.2196/52143] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 02/29/2024] [Accepted: 07/09/2024] [Indexed: 09/11/2024] Open
Abstract
BACKGROUND Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are associated with high mortality, morbidity, and poor quality of life and constitute a substantial burden to patients and health care systems. New approaches to prevent or reduce the severity of AECOPD are urgently needed. Internationally, this has prompted increased interest in the potential of remote patient monitoring (RPM) and digital medicine. RPM refers to the direct transmission of patient-reported outcomes, physiological, and functional data, including heart rate, weight, blood pressure, oxygen saturation, physical activity, and lung function (spirometry), directly to health care professionals through automation, web-based data entry, or phone-based data entry. Machine learning has the potential to enhance RPM in chronic obstructive pulmonary disease by increasing the accuracy and precision of AECOPD prediction systems. OBJECTIVE This study aimed to conduct a dual systematic review. The first review focuses on randomized controlled trials where RPM was used as an intervention to treat or improve AECOPD. The second review examines studies that combined machine learning with RPM to predict AECOPD. We review the evidence and concepts behind RPM and machine learning and discuss the strengths, limitations, and clinical use of available systems. We have generated a list of recommendations needed to deliver patient and health care system benefits. METHODS A comprehensive search strategy, encompassing the Scopus and Web of Science databases, was used to identify relevant studies. A total of 2 independent reviewers (HMGG and CM) conducted study selection, data extraction, and quality assessment, with discrepancies resolved through consensus. Data synthesis involved evidence assessment using a Critical Appraisal Skills Programme checklist and a narrative synthesis. Reporting followed PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. RESULTS These narrative syntheses suggest that 57% (16/28) of the randomized controlled trials for RPM interventions fail to achieve the required level of evidence for better outcomes in AECOPD. However, the integration of machine learning into RPM demonstrates promise for increasing the predictive accuracy of AECOPD and, therefore, early intervention. CONCLUSIONS This review suggests a transition toward the integration of machine learning into RPM for predicting AECOPD. We discuss particular RPM indices that have the potential to improve AECOPD prediction and highlight research gaps concerning patient factors and the maintained adoption of RPM. Furthermore, we emphasize the importance of a more comprehensive examination of patient and health care burdens associated with RPM, along with the development of practical solutions.

Effects of the teach-back method on the health status of patients with chronic obstructive pulmonary disease: a real-world community-based cluster-randomized controlled trial. J Thorac Dis 2024; 16:5209-5221. [PMID: 39268140 PMCID: PMC11388232 DOI: 10.21037/jtd-23-1895] [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: 12/13/2023] [Accepted: 07/05/2024] [Indexed: 09/15/2024]
Abstract
Background The teach-back method (TBM), also known as the "show-me" method, is a technique for verifying patients' understanding of health-related information that has been recommended for improving health literacy. However, the research on TBM effect on the outcomes of chronic obstructive pulmonary disease (COPD) patients is limited. Therefore, the aim of this study was to examine the effect of a TBM intervention on the health status of COPD patients. Methods This real-world community-based cluster-randomized controlled trial enrolled 1,688 patients with COPD from 18 communities in China. Participants received either TBM plus usual care (UC) or UC only. General practitioners were trained in TBM before the intervention. The primary outcomes were depression and anxiety symptoms, as measured by the Hospital Anxiety and Depression Scale (HADS). The secondary outcomes were health-related quality of life and dyspnea, as measured by the COPD Assessment Test (CAT). Dyspnea was assessed using the modified Medical Research Council (mMRC) dyspnea scale. Data on acute exacerbations and deaths were extracted from medical records. Lung function was expressed as the forced expiratory volume in 1 second as a percentage of the predicted value [FEV1 (% pred)]. Results In total, 336 of the 853 COPD patients in the intervention group (TBM plus UC) had comorbid depression, compared with 329 of the 835 in the control group (UC only). The TBM group showed a significantly greater improvement in HADS depression and anxiety subscale scores (HADS-D and HADS-A, respectively) than the UC group at12 months (t =8.34, P<0.001; t=12.18, P<0.001). The CAT and mMRC scores were significantly lower in the TBM than UC group at 12 months (t=8.43, P<0.001; t=7.23, P<0.001). The numbers of acute exacerbations and deaths were significantly lower in the TBM than UC group at 12 months (mean MCF values were 0.35 and 0.56, respectively [difference of 0.22; 95% confidence interval (CI): -0.41, -0.02; χ2=9.63, P<0.001]. The FEV1 (% pred) was significantly higher in the TBM than UC group at 12 months (t=7.45, P<0.001). Conclusions General practitioners can use TBM interventions to effectively reduce anxiety, depression, and dyspnea symptoms, decrease the frequency of exacerbations and likelihood of death, and improve health-related quality of life and pulmonary function in patients with COPD. Trial Registration The trial was registered on the Chinese Clinical Trials Registry (reference: ChiCTR-TRC-12001958).

Abstract
INTRODUCTION Chronic obstructive pulmonary disease (COPD) is the third most common cause of death worldwide and 24% of the patients die within 5 years of diagnosis. AREAS COVERED The epidemiology of mortality and the interventions that reduce it are reviewed. The increasing global deaths reflect increases in population sizes, increasing life expectancy and reductions in other causes of death. Strategies to reduce mortality aim to prevent the development of COPD and improve the survival of individuals. Historic changes in mortality give insights: improvements in living conditions and nutrition, and later improvements in air quality led to a large fall in mortality in the early 20th century. The smoking epidemic temporarily reversed this trend.Older age, worse lung function and exacerbations are risk factors for death. Single inhaler triple therapy; smoking cessation; pulmonary rehabilitation; oxygen therapy; noninvasive ventilation; and surgery reduce mortality in selected patients. EXPERT OPINION The importance of addressing the global burden of mortality from COPD must be recognized. Steps must be taken to reduce it, by reducing exposure to risk factors, assessing individual patients' risk of death and using treatments that reduce the risk of death. Mortality rates are falling in countries that have adopted a comprehensive approach to COPD prevention and treatment.

Abstract
Chronic obstructive pulmonary disease (COPD), a heterogeneous respiratory disease driven by various genetic and environmental factors, presents significant challenges in diagnosis and management. Traditional approaches focused on phenotypic classification, but recent paradigms emphasize identifying and addressing treatable traits to personalize treatment strategies. Treatable traits facilitate personalized interventions, optimizing symptom control, and reducing exacerbation risk. Dyspnea and exacerbations, recognized as key traits, guide treatment decisions and follow-up management. Various interventions, including bronchodilators, corticosteroids, and lifestyle modifications, target specific traits like airway inflammation, mucus overproduction, and emphysema. Strategies for assessing and addressing treatable traits during initial encounters and follow-up visits enhance disease monitoring and treatment efficacy. Comprehensive trait assessment demands resources and specialized monitoring, posing barriers to widespread implementation. The lack of standardized protocols and evolving evidence further complicates decision-making and clinical practice. Despite these challenges, the shift toward treatable traits-based management signifies a pivotal advancement in COPD care, emphasizing holistic approaches tailored to individual patient needs. Recognizing and addressing treatable traits offers personalized interventions, enhancing symptom control and disease management. Embracing treatable traits-based approaches holds promise for improving clinical outcomes and enhancing the quality of life for individuals living with COPD.

Associations between outpatient care and later hospital admissions for patients with chronic obstructive pulmonary disease - a registry study from Norway. BMC Health Serv Res 2024; 24:500. [PMID: 38649963 PMCID: PMC11036724 DOI: 10.1186/s12913-024-10975-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Accepted: 04/10/2024] [Indexed: 04/25/2024] Open
Abstract
BACKGROUND Although chronic obstructive pulmonary disease (COPD) admissions put a substantial burden on hospitals, most of the patients' contacts with health services are in outpatient care. Traditionally, outpatient care has been difficult to capture in population-based samples. In this study we describe outpatient service use in COPD patients and assess associations between outpatient care (contact frequency and specific factors) and next-year COPD hospital admissions or 90-day readmissions. METHODS Patients over 40 years of age residing in Oslo or Trondheim at the time of contact in the period 2009-2018 were identified from the Norwegian Patient Registry (in- and outpatient hospital contacts, rehabilitation) and the KUHR registry (contacts with GPs, contract specialists and physiotherapists). These were linked to the Regular General Practitioner registry (characteristics of the GP practice), long-term care data (home and institutional care, need for assistance), socioeconomic and-demographic data from Statistics Norway and the Cause of Death registry. Negative binomial models were applied to study associations between combinations of outpatient care, specific care factors and next-year COPD hospital admissions and 90-day readmissions. The sample consisted of 24,074 individuals. RESULTS A large variation in the frequency and combination of outpatient service use for respiratory diagnoses (GP, emergency room, physiotherapy, contract specialist and outpatient hospital contacts) was apparent. GP and outpatient hospital contact frequency were strongly associated to an increased number of next-year hospital admissions (1.2-3.2 times higher by increasing GP frequency when no outpatient hospital contacts, 2.4-5 times higher in combination with outpatient hospital contacts). Adjusted for healthcare use, comorbidities and sociodemographics, outpatient care factors associated with lower numbers of next-year hospitalisations were fees indicating interaction between providers (7% reduction), spirometry with GP or specialist (7%), continuity of care with GP (15%), and GP follow-up (8%) or rehabilitation (18%) within 30 days vs. later following any current year hospitalisations. For 90-day readmissions results were less evident, and most variables were non-significant. CONCLUSION As increased use of outpatient care was strongly associated with future hospitalisations, this further stresses the need for good communication between providers when coordinating care for COPD patients. The results indicated possible benefits of care continuity within and interaction between providers.

INTRODUCTION The EXAcerbations of Chronic obstructive lung disease (COPD) and their OutcomeS (EXACOS) International Study aimed to quantify the rate of severe exacerbations and examine healthcare resource utilisation (HCRU) and clinical outcomes in patients with COPD from low-income and middle-income countries. METHODS EXACOS International was an observational, cross-sectional study with retrospective data collection from medical records for a period of up to 5 years. Data were collected from 12 countries: Argentina, Brazil, Chile, Colombia, Costa Rica, Dominican Republic, Guatemala, Hong Kong, Mexico, Panama, Russia and Taiwan. The study population comprised patients ≥40 years of age with COPD. Outcomes/variables included the prevalence of severe exacerbations, the annual rate of severe exacerbations and time between severe exacerbations; change in lung function over time (measured by the forced expiratory volume in 1 s (FEV1)); peripheral blood eosinophil counts (BECs) and the prevalence of comorbidities; treatment patterns; and HCRU. RESULTS In total, 1702 patients were included in the study. The study population had a mean age of 69.7 years, with 69.4% males, and a mean body mass index of 26.4 kg/m2. The mean annual prevalence of severe exacerbations was 20.1%, and 48.4% of patients experienced ≥1 severe exacerbation during the 5-year study period. As the number of severe exacerbations increased, the interval between successive exacerbations decreased. A statistically significant decrease in mean (SD) FEV1 from baseline to post-baseline was observed in patients with ≥1 severe exacerbation (1.23 (0.51) to 1.13 (0.52) L; p=0.0000). Mean BEC was 0.198 x109 cells/L, with 64.7% of patients having a BEC ≥0.1 x109 cells/L and 21.3% having a BEC ≥0.3 x109 cells/L. The most common comorbidity was hypertension (58.3%). An increasing number of severe exacerbations per year was associated with greater HCRU. DISCUSSION The findings presented here indicate that effective treatment strategies to prevent severe exacerbations in patients with COPD remain a significant unmet need in low-income and middle-income countries.

Do pulmonary rehabilitation programmes improve outcomes in patients with COPD posthospital discharge for exacerbation: a systematic review and meta-analysis. Thorax 2024; 79:438-447. [PMID: 38350731 DOI: 10.1136/thorax-2023-220333] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Accepted: 01/23/2024] [Indexed: 02/15/2024]
Abstract
INTRODUCTION Previous systematic reviews have provided heterogeneous and differing estimates for the efficacy of pulmonary rehabilitation following exacerbations of chronic obstructive pulmonary disease (COPD). The aim of this review was to examine the efficacy of pulmonary rehabilitation programmes initiated within 3 weeks of hospital discharge following an exacerbation of COPD. METHODS An update of a previous Cochrane review was undertaken using the Cochrane Airways Review Group Specialised Register. Searches were conducted from October 2015 to August 2023 for studies that initiated pulmonary rehabilitation within 3 weeks of hospital discharge. Studies assessing the impact of solely inpatient pulmonary rehabilitation were excluded. Forest plots were generated using a generic inverse variance random effects method. RESULTS Seventeen studies were included. Posthospital discharge pulmonary rehabilitation reduced hospital re-admissions (OR 0.48, 95% CI 0.30 to 0.77, I2=67%), improved exercise capacity (6 min walk test, mean difference (MD) 57 m, 95% CI 29 to 86, I2=89%; incremental shuttle walk test, MD 43 m, 95% CI 6 to 79, I2=81%), health-related quality of life (St. George's Respiratory Questionnaire, MD -8.7 points, 95% CI -12.5 to -4.9, I2=59%; Chronic Respiratory Disease Questionnaire (CRQ)-emotion, MD 1.0 points, 95% CI 0.4 to 1.6, I2=74%; CRQ-fatigue, MD 0.9 points, 95% CI 0.1 to 1.6, I2=91%), and dyspnoea (CRQ-dyspnoea, MD 1.0 points, 95% CI 0.3 to 1.7, I2=87%; modified Medical Research Council Dyspnoea Scale, MD -0.3 points, 95% CI -0.5 to -0.1, I2=60%). Significant effects were not observed for CRQ-mastery, COPD assessment test, EuroQol-5 Dimension-5 Level and mortality. No intervention-related adverse events were reported. DISCUSSION Pulmonary rehabilitation delivered posthospital discharge for exacerbation of COPD results in a reduction in hospital re-admissions and improvements in exercise capacity, health-related quality of life and dyspnoea in the absence of any intervention-related adverse events.

Exercise training initiated early during hospitalisation in individuals with chronic obstructive pulmonary disease is safe and improves exercise capacity and physical function at hospital discharge: A systematic review and meta-analysis. Respir Med 2024; 223:107554. [PMID: 38307320 DOI: 10.1016/j.rmed.2024.107554] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Revised: 01/29/2024] [Accepted: 01/30/2024] [Indexed: 02/04/2024]
Abstract
BACKGROUND AND OBJECTIVE Earlier reviews of exercise in people during exacerbation of chronic obstructive pulmonary disease (COPD) included studies where exercise training was initiated late during hospital admission or shortly following hospital discharge. Our question was: in adults hospitalised with an exacerbation of COPD, does initiating exercise training early during an admission versus not initiating exercise training during admission, change outcomes measured at discharge? METHODS Systematic review and meta-analysis. Database searches of PubMed, the Cochrane Library, PEDro and EMBASE conducted in December 2021 and updated in January 2024. Studies were included if they had at least one group that was prescribed exercise training within 48 h of hospital admission (experimental) and at least one group that received usual care which did not include prescribed exercise training (control). Outcomes included exercise capacity, physical function, adverse events and uptake of outpatient pulmonary rehabilitation programs. RESULTS Ten studies (423 participants; mean FEV1 ranging from 26 % to 50 % predicted) were included. At discharge, compared to the control group, the experimental group demonstrated better exercise capacity (standardised mean difference (SMD) 0.58, 95 % confidence interval (CI) 0.32 to 0.83; five studies, moderate effect, low certainty evidence) and physical function (SMD -0.54, 95 % CI -0.86 to -0.22; four studies, moderate effect, low certainty evidence). No observed serious adverse events were reported. None of the studies reported uptake of pulmonary rehabilitation following discharge. CONCLUSION In adults with an exacerbation of COPD, exercise training prescribed within 48 h of hospitalisation was safe and improved exercise capacity and physical function.

Abstract
Objective To describe the burden of moderate to severe exacerbations and all-cause mortality; the secondary objectives were to analyze treatment patterns and changes over follow-up. Design Observational, multicenter, retrospective, cohort study with a three year follow-up period. Setting Ten Italian academic secondary- and tertiary-care centers. Participants Patients with a confirmed diagnosis of COPD referring to the outpatient clinics of the participating centers were retrospectively recruited. Primary and Secondary Outcome Measures Annualized frequency of moderate and severe exacerbations stratified by exacerbation history prior to study enrollment. Patients were classified according to airflow obstruction, GOLD risk categories, and divided in 4 groups: A = no exacerbations; B = 1 moderate exacerbation; C = 1 severe exacerbation; D = ≥2 moderate and/or severe exacerbations. Overall all-cause mortality stratified by age, COPD category, and COPD therapy. A logistic regression model assessed the association of clinical characteristics with mortality. Results 1111 patients were included (73% males), of which 41.5% had a history of exacerbations. As expected, the proportion of patients experiencing ≥1 exacerbation during follow-up increased according to pre-defined study risk categories (B: 79%, C: 84%, D: 97.4%). Overall, by the end of follow-up, 45.5% of patients without a history of exacerbation experienced an exacerbation (31% of which severe), and 13% died. Deceased patients were significantly older, more obstructed and hyperinflated, and more frequently active smokers compared with survivors. Severe exacerbations were more frequent in patients that died (23.5%, vs 10.2%; p-value: 0.002). Chronic heart failure and ischemic heart disease were the only comorbidities associated with a higher odds ratio (OR) for death (OR: 2.2, p-value: 0.001; and OR: 1.9, p-value: 0.007). Treatment patterns were similar in patients that died and survivors. Conclusion Patients with a low exacerbation risk are exposed to a significant future risk of moderate/severe exacerbations. Real life data confirm the strong association between mortality and cardiovascular comorbidities in COPD.

Development of a performance-based toolkit of the treatable traits of functioning in hospitalised patients with exacerbation of COPD: a survey-based study protocol. ERJ Open Res 2024; 10:00809-2023. [PMID: 38651092 PMCID: PMC11033727 DOI: 10.1183/23120541.00809-2023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Accepted: 01/05/2024] [Indexed: 04/25/2024] Open
Abstract
Background The management of COPD has been based on the premise of identifying problems that guide personalised treatment based on a multidimensional assessment, known as treatable traits. Exacerbation of COPD (ECOPD) results in physical and functional impairments, limitation of daily activities and negative impact on patients' quality of life and prognosis. In this context, identifying treatable traits in patients with ECOPD is essential to properly guide individualised patient care. There is a need to develop a performance-based toolkit to identify the main treatable traits of functioning in hospitalised patients with ECOPD. Methods and analysis This is a study protocol of a survey method observational study to develop a performance-based toolkit. The study will include the following steps: 1) definition of treatable traits by both physiotherapists who provide or have provided care to hospitalised patients with ECOPD on a regular basis, and patients who have experienced at least one ECOPD which required hospitalisation; 2) selection of the most appropriate measures (markers) for each treatable trait based on established criteria and a previous systematic review; and 3) implementation of the toolkit in a pilot/feasibility study with hospitalised patients with ECOPD. Conclusion The development of a feasible performance-based toolkit with the best markers for each key treatable trait of functioning in hospitalised patients with ECOPD will make it possible to create individualised patient care for the specific demands of these patients.

Abstract
The respiratory pathogen nontypeable Haemophilus influenzae (NTHi) is the most common cause of exacerbation of chronic obstructive pulmonary disease (COPD), of which an excessive inflammatory response is a hallmark. With the limited success of current medicines there is an urgent need for the development of novel therapeutics that are both safe and effective. In this study, we explored the regulatory potential of pomegranate-derived peptides Pug-1, Pug-2, Pug-3, and Pug-4 on NTHi-induced inflammation. Our results clearly showed that to varying degrees the Pug peptides inhibited NTHi-induced production of IL-1β, a pivotal cytokine in COPD, and showed that these effects were not related to cytotoxicity. Pug-4 peptide exhibited the most potent inhibitory activity. This was demonstrated in all studied cell types including murine (RAW264.7) and human (differentiated THP-1) macrophages as well as human lung epithelial cells (A549). Substantial reduction by Pug-4 of TNF-α, NO and PGE2 in NTHi-infected A549 cells was also observed. In addition, Pug-4 strongly inhibited the expression of nuclear-NF-κB p65 protein and the NF-κB target genes (determined by IL-1β, TNF-α, iNOS and COX-2 mRNA expression) in NTHi-infected A549 cells. Pug-4 suppressed the expression of NLRP3 and pro-IL-1β proteins and inhibited NTHi-mediated cleavage of caspase-1 and mature IL-1β. These results demonstrated that Pug-4 inhibited NTHi-induced inflammation through the NF-κB signaling and NLRP3 inflammasome activation. Our findings herein highlight the significant anti-inflammatory activity of Pug-4, a newly identified peptide from pomegranate, against NTHi-induced inflammation. We therefore strongly suggest the potential of the Pug-4 peptide as an anti-inflammatory medicine candidate for treatment of NTHi-mediated inflammation.

Abstract
Purpose Chronic obstructive pulmonary disease (COPD) concurrent with respiratory failure (RF) is devastating, and may result in death and disability. Systemic immune-inflammation index (SII) is a new prognostic biomarker linked to unfavorable outcomes of acute coronary syndrome, ischemic stroke, and heart failure. Nonetheless, its role in COPD is rarely investigated. Consequently, this study intends to assess the accuracy of SII in predicting the prognosis of COPD. Patients and Methods The clinical information was retrospectively acquired from the Medical Information Mart for Intensive Care-IV database. The outcomes encompassed the incidence of RF and mortality. The relationship between different SII and outcomes was examined utilizing the Cox proportional-hazards model and restricted cubic splines. Kaplan-Meier analysis was employed for all-cause mortality. Results The present study incorporated 1653 patients. During hospitalization, 697 patients (42.2%) developed RF, and 169 patients (10.2%) died. And 637 patients (38.5%) died during long-term follow-up. Higher SII increased the risk of RF (RF: HR: 1.19, 95% CI 1.12-1.28, P<0.001), in-hospital mortality (HR: 1.22, 95% CI 1.07-1.39, P=0.003), and long-term follow-up mortality (HR: 1.12, 95% CI 1.05-1.19, P<0.001). Kaplan-Meier analysis suggested a significantly elevated risk of all-cause death (log-rank P<0.001) in patients with higher SII, especially during the short-term follow-up period of 21 days. Conclusion SII is closely linked to an elevated risk of RF and death in COPD patients. It appears to be a potential predictor of the prognosis of COPD patients, which is helpful for the risk stratification of this population. However, more prospective studies are warranted to consolidate our conclusion.

Abstract
Lung tissue has a certain regenerative ability and triggers repair procedures after injury. Under controllable conditions, lung tissue can restore normal structure and function. Disruptions in this process can lead to respiratory system failure and even death, causing substantial medical burden. The main types of respiratory diseases are chronic obstructive pulmonary disease (COPD), idiopathic pulmonary fibrosis (IPF), and acute respiratory distress syndrome (ARDS). Multiple cells, such as lung epithelial cells, endothelial cells, fibroblasts, and immune cells, are involved in regulating the repair process after lung injury. Although the mechanism that regulates the process of lung repair has not been fully elucidated, clinical trials targeting different cells and signaling pathways have achieved some therapeutic effects in different respiratory diseases. In this review, we provide an overview of the cell type involved in the process of lung regeneration and repair, research models, and summarize molecular mechanisms involved in the regulation of lung regeneration and fibrosis. Moreover, we discuss the current clinical trials of stem cell therapy and pharmacological strategies for COPD, IPF, and ARDS treatment. This review provides a reference for further research on the molecular and cellular mechanisms of lung regeneration, drug development, and clinical trials.

Abstract
Vilanterol is a once-daily dose inhaler prescribed for asthma and chronic obstructive pulmonary disease. This study involved an investigation of vilanterol stability under acidic, basic, oxidative, thermal, and photolytic stress conditions. UPLC method was developed and validated for the analysis of vilanterol with its degradants. The drug was stable under photolytic and thermal stress conditions and degraded under acidic, basic, and oxidative stress conditions. Degradation kinetics was performed for acidic, basic and oxidative stress conditions. Kinetics parameters, K, half-life time (t1/2) and shelf-life time (t90) were assessed, and the degradation followed first order reaction. The method was linear from 0.10 to 100.00 µg mL-1 with accuracy, inter-day and intra-day precision from 99.45 to 100.02%, 0.391-0.694 and 0.041-0.345, respectively. Mass spectrometry was employed to elucidate the structure of the degradants, and the results revealed that certain degradation products were comparable to vilanterol metabolites. The World Anti-Doping Agency has prohibited the presence of vilanterol and its metabolites in athletes' urine except for exercise bronchoconstriction with limited dose. So, quantification of vilanterol in the presence of its degradants was performed in human urine. The results revealed that the method was linear in range of 1.00 to 100.00 µg mL-1. Samples collection and experimental protocol was performed according to the guidelines of the Research Ethics Committee of the Faculty of Pharmacy, the British University in Egypt with approval No. CH-2305.

Int J Chron Obstruct Pulmon Dis 2024; 19:281-296. [PMID: 38292138 PMCID: PMC10824610 DOI: 10.2147/copd.s423993] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Accepted: 12/19/2023] [Indexed: 02/01/2024] Open
Abstract
Purpose Chronic obstructive pulmonary disease (COPD) and asthma are associated with chronic inflammation of the respiratory tract; despite some overlap of symptoms, they are considered separate disorders. Triple therapy is recommended for patients with COPD and asthma whose symptoms remain uncontrolled despite dual therapy. There are limited real-world studies evaluating outcomes among patients with COPD and asthma who are receiving inhaled triple therapy. This United States (US)-based real-world study aimed to evaluate clinical and economic outcomes among patients with COPD and asthma receiving single-inhaler triple therapy (fluticasone furoate/umeclidinium/vilanterol [FF/UMEC/VI]). Patients and Methods Retrospective pre-post study using claims data from the Optum Clinformatics® database. Patients with COPD and asthma were indexed on the first date of FF/UMEC/VI prescription (1 October 2017-31 March 2019). Each patient acted as their own control. Patients were required to have continuous health plan enrollment for 12 months prior to (pre-treatment) and following (post-treatment) index. Exacerbations, all-cause and COPD-related healthcare resource utilization, and costs were compared before and after FF/UMEC/VI initiation. Results Overall, 2743 patients were included (mean age: 71 years; 64% female). Cardiovascular disease was the most prevalent comorbidity during both the pre- and post-treatment periods (90% for both periods). There was a lower proportion of patients with ≥1 COPD exacerbation or ≥1 asthma exacerbation post-treatment versus pre-treatment (51% vs 57%, p<0.0001, and 22% vs 32%, p<0.0001, respectively). Fewer patients had ≥1 all-cause office visit post-treatment versus pre-treatment (99.3% vs 99.7%, p=0.0329); more patients had ≥1 COPD-related office visit post-treatment versus pre-treatment (89.6% vs 87.5%, p=0.0035). Total all-cause healthcare costs were significantly higher post-treatment versus pre-treatment ($72,809 vs $63,734, p<0.0001). The driver of increased costs appeared to be primarily non-COPD-related (COPD-related costs: post-treatment $27,779 vs pre-treatment $25,081, p=0.0062). Conclusion FF/UMEC/VI reduced exacerbations among patients with COPD and asthma in a real-world setting in the US.

Real-World Effectiveness of Fluticasone Furoate/Umeclidinium/Vilanterol Once-Daily Single-Inhaler Triple Therapy for Symptomatic COPD: The ELLITHE Non-Interventional Trial. Int J Chron Obstruct Pulmon Dis 2024; 19:205-216. [PMID: 38249826 PMCID: PMC10800114 DOI: 10.2147/copd.s427770] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Accepted: 12/08/2023] [Indexed: 01/23/2024] Open
Abstract
Purpose Real-life effectiveness data on once-daily single-inhaler triple therapy (odSITT) with the inhaled corticosteroid fluticasone furoate (FF), the long-acting muscarinic antagonist umeclidinium (UMEC), and the long-acting β2-agonist vilanterol (VI) in patients with chronic obstructive pulmonary disease (COPD) are important to complement evidence from well-controlled randomized clinical trials. Effectiveness of odSITT was quantified by assessing health status and symptoms in usual care. Patients and Methods ELLITHE was a single-country (Germany), multicenter, open-label, non-interventional effectiveness study between 2020 and 2022, evaluating the effect of treatment initiation with FF/UMEC/VI 100/62.5/25 µg once-daily via the ELLIPTA inhaler on improvements in clinical outcomes versus baseline in COPD patients. The primary endpoint was the change in the total COPD Assessment Test (CAT) score between baseline and month 12. Key secondary endpoints included change in CAT score over time, occurrence of exacerbations until month 12, changes in forced expiratory volume in one second (FEV1), inhaler adherence, and safety. Results Nine hundred and six patients were included (age 66.6 years, 55.6% male, mean FEV1 52.6% of predicted, mean CAT 21.5 units, 1.4 exacerbations/year pre-study). About 63.9% of patients were escalated from dual therapies, and 18% were switched from multiple-inhaler triple therapies. Reductions in CAT score at month 12 were statistically significant and above the threshold of clinical importance (-2.6 units; p < 0.0001). CAT score also improved at interim visits. CAT improvements were more pronounced in patients with high baseline scores and better inhaler adherence. Exacerbations during follow-up were rare (0.2 events/year) compared to pre-study (1.4 events/year). FEV1 was improved by 93 mL (p < 0.0001). No new safety effects were observed. Conclusion In usual care, treatment with odSITT resulted in significant and clinically relevant improvements of CAT score and FEV1 in COPD patients, regardless of the occurrence of exacerbations. These findings challenge the current guideline recommendations for SITT only in patients experiencing exacerbations.

Abstract
Introduction Considering the role of bacteria in the onset of acute exacerbation of COPD (AECOPD), we hypothesized that the use of influenza-Streptococcus pneumoniae vaccination, oral probiotics or inhaled amikacin could prevent AECOPD. Methods In this pilot prospective, muti-central, randomized trial, moderate-to-very severe COPD subjects with a history of moderate-to-severe exacerbations in the previous year were enrolled and assigned in a ratio of 1:1:1:1 into 4 groups. All participants were managed based on the conventional treatment recommended by GOLD 2019 report for 3 months, with three groups receiving additional treatment of inhaled amikacin (0.4 g twice daily, 5-7 days monthly for 3 months), oral probiotic Lactobacillus rhamnosus GG (1 tablet daily for 3 months), or influenza-S. pneumoniae vaccination. The primary endpoint was time to the next onset of moderate-to-severe AECOPD from enrollment. Secondary endpoints included CAT score, mMRC score, adverse events, and survival in 12 months. Results Among all 112 analyzed subjects (101 males, 96 smokers or ex-smokers, mean ± SD age 67.19 ± 7.39 years, FEV1 41.06 ± 16.09% predicted), those who were given dual vaccination (239.7 vs. 198.2 days, p = 0.044, 95%CI [0.85, 82.13]) and oral probiotics (248.8 vs. 198.2 days, p = 0.017, 95%CI [7.49, 93.59]) had significantly delayed onset of next moderate-to-severe AECOPD than those received conventional treatment only. For subjects with high symptom burden, the exacerbations were significantly delayed in inhaled amikacin group as compared to the conventional treatment group (237.3 vs. 179.1 days, p = 0.009, 95%CI [12.40,104.04]). The three interventions seemed to be safe and well tolerated for patient with stable COPD. Conclusion The influenza-S. pneumoniae vaccine and long-term oral probiotic LGG can significantly delay the next moderate-to-severe AECOPD. Periodically amikacin inhalation seems to work in symptomatic patients. The findings in the current study warrants validation in future studies with microbiome investigation.Clinical trial registration:https://clinicaltrials.gov/, identifier NCT03449459.

Abstract
In Japan, exacerbations are underreported compared with other countries, possibly due in part to a failure to recognize them. This study aimed to create a simple chronic obstructive pulmonary disease (COPD) Exacerbation Recognition Tool (CERT-J) specifically for Japanese patients. Patients ≥40 years with confirmed COPD or asthma-COPD overlap were included. Focus groups were held to identify words and phrases used by patients to describe symptoms associated with an exacerbation, resulting in candidate items being identified. Following cognitive debriefing, the items were refined based on item frequency, level of endorsement and effect of demographic factors. Exploratory factor analysis (EFA) was then performed to inform an expert panel's choice of items to form the new tool. A total of 41 patients were included in the focus groups and nine patients performed the cognitive debrief. Following this, the expert panel identified 26 items for testing in a further 100 patients (mean age 72 years, forced expiratory volume in 1 s 54.8% predicted and 1.8 exacerbations in the preceding 12 months). Eleven items were associated with breathlessness or activity limitation and seven of these were the most frequently endorsed. EFA identified four factors, with one (breathlessness) being dominant. The expert panel recommended that the CERT-J should include six items: breathlessness and activity limitation (3 items), cough (1 item) and phlegm (2 items). The final CERT-J should benefit patients with COPD by providing them with an increased understanding and recognition of exacerbations.Clinical Trial Registration: GSK K.K (jRCT1080224526).

Abstract
Purpose Readmission of chronic obstructive pulmonary disease (COPD) has been used as a measure of performance for COPD care. This study aimed to determine the rate of readmission of COPD in tertiary care hospital in Malaysia and its associated factors. Patients and Methods A retrospective cohort study was conducted at a tertiary care hospital in Malaysia from 1st January to 21st May 2019. Seventy admissions for COPD exacerbation involving 58 patients were analyzed. Results The majority of the patients were male (89.8%), had a mean age of 71.95 ± 7.24 years and a median smoking history of 40 (IQR = 25) pack-years, 84.5% were in GOLD group D and 91.4% had a mMRC grading of 2 or greater. Approximately 60.3% had upper or lower respiratory tract infection as the cause of exacerbation; one in five patients had uncompensated hypercapnic respiratory failure at presentation, and 27.6% needed mechanical ventilatory support. Approximately 43.1% of patients had a history of exacerbation that required hospitalisation in the past year. The mean blood eosinophil concentration was 0.38 ± 0.46 x109 cells/L. The 30-day readmission rate was 20.3%, revisit rate to the emergency room within 30 days after discharge was 3.4%, and in-hospital mortality rate was 1.7%. Among all characteristics, a higher baseline mMRC grade (p = 0.038) and history of exacerbation in the past 1 year (p < 0.001) were statistically associated with 30-day readmission. Conclusion The 30-day readmission rate for COPD exacerbation in a Malaysian tertiary hospital is similar to the rates in high-income countries. Exacerbation in the previous year and a higher baseline mMRC grading were significant risk factors for 30-day readmission in patients with COPD. Strategies of COPD management should concentrate on improvement of symptoms control by optimisation of pharmacotherapy, and early initiation of pulmonary rehabilitation, and structured integrated care programs to reduce readmission rates.

Impact of acute exacerbations of COPD on patients' health status beyond pulmonary function: A scoping review. Pulmonology 2023; 29:518-534. [PMID: 35715333 DOI: 10.1016/j.pulmoe.2022.04.004] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2021] [Revised: 03/30/2022] [Accepted: 04/10/2022] [Indexed: 11/21/2022] Open
Abstract
This scoping review summarized the evidence regarding the impact of acute exacerbations of COPD (AECOPD) on patients' health status beyond pulmonary function. PubMed, Embase, and Web of Science were searched. Prospective cohort studies assessing the health status of patients with COPD in a stable phase of the disease and after a follow-up period (where at least one AECOPD occurred) were included. An integrated assessment framework of health status (i.e., physiological functioning, complaints, functional impairment, quality of life) was used. Twenty-two studies were included. AECOPD acutely affected exercise tolerance, quadriceps muscle strength, physical activity levels, symptoms of dyspnoea and fatigue, and impact of the disease. Long-term effects on quadriceps muscle strength, symptoms of dyspnoea and depression, and quality of life were found. Repeated exacerbations negatively impacted the fat-free mass, levels of dyspnoea, impact of the disease and quality of life. Conflicting evidence was found regarding the impact of repeated exacerbations on exercise tolerance and physical activity levels. AECOPD have well-established acute and long-term adverse effects on health status beyond pulmonary function; nevertheless, the recovery trajectory and the impact of repeated exacerbations are still poorly studied. Further prospective research is recommended to draw firm conclusions on these aspects.

[PMID: 37915323 PMCID: PMC10616861 DOI: 10.3389/fmed.2023.1195481] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Accepted: 10/02/2023] [Indexed: 11/03/2023] Open
Abstract
Background This study assesses whether out-of-hospital coaching of re-hospitalized, severe COPD patients by specialized respiratory nurses is feasible in terms of cost-effectiveness, implementation, and recipient acceptability. The coaching was aimed at improving patients' health management abilities, motivation for healthy behavior, strengthening the professional and informal care network, stimulating physiotherapy treatment and exercise training, improving knowledge on symptom recognition and medication use, and providing safety and support. Methods Cost-effectiveness of 6 months of out-of-hospital coaching was assessed based on a before-after intervention design, with real-life data and one-year follow-up. A total of 170 patients were included. Primary (questionnaires, meeting reports) and secondary data (insurance reimbursement data) were collected in one province in the Netherlands. The implementing and recipient acceptability was assessed based on the number of successfully delivered coaching sessions, questionnaire response rate, Patient Reported Experience Measure, and interviews with coaches. Results Post-intervention, the COPD-related hospitalization rate was reduced by 24%, and patients improved in terms of health status, anxiety, and nutritional status. Patients with a high mental burden and a poor score for health impairment and wellbeing at the start of the intervention showed the greatest reduction in hospitalizations. The coaching service was successfully implemented and considered acceptable by recipients, based on patient and coach satisfaction and clinical use of patient-reported measures. Conclusion The study demonstrates the value of coaching patients out-of-hospital, with a strong link to primary care, but with support of hospital expertise, thereby adding to previous studies on disease- or self-management support in either primary or secondary care settings. Patients benefit from personal attention, practical advice, exercise training, and motivational meetings, thereby improving health status and reducing the likelihood of re-hospitalization and its associated costs.

[PMID: 37832130 PMCID: PMC10578682 DOI: 10.1097/md.0000000000035474] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2023] [Accepted: 09/13/2023] [Indexed: 10/15/2023] Open
Abstract
Chronic respiratory diseases (CRDs) are among the leading cause of mortality worldwide. While pharmacological approaches are commonly used to manage symptoms, non-pharmacological management of CRDs is considered crucial in preventing disease progression and improving patient self-efficacy. To describe the perceived effectiveness of non-pharmacological management of CRDs among CRD patients and determine whether the CRD patients perceptions of the effectiveness of non-pharmacological management are associated with their demographic characteristics. An analytic cross-sectional study design was utilized. The non-pharmacological management practices of CRD patients and their perception of the effectiveness of these therapeutic measures were assessed using a researcher-developed questionnaire. Data collection took place in primary healthcare centers in Al Ahsa, Saudi Arabia from October 2021 to March 2022. The proportion of CRD patients who perceived that non-pharmacological interventions were effective was computed. Binary logistic regression was performed to determine the association between the demographic characteristics of the respondents and their perception of the effectiveness of non-pharmacological management. Among the 390 respondents, 42% perceived that non-pharmacological measures were effective. Half of the respondents believed that smoking cessation, influenza vaccination, improving physical activity, and nutrition support helped alleviate CRD symptoms, while less than half of the respondents considered pulmonary rehabilitation, educational programs, and oxygen therapy effective measures to control symptoms. Women were found to be 3.24 times more likely to perceive non-pharmacological interventions as effective (P < .0000) compared to men. Those with university-level education were 66.6% less likely to consider non-pharmacological interventions to be effective (P < .0000) than those who completed preuniversity-level education. Age and marital status did not significantly influence perceptions of effectiveness. Differences in the perceptions of the effectiveness of various non-pharmacological measures to alleviate CRD symptoms existed among the CRD patients of Al Ahsa. The perception of effectiveness was significantly associated with the patient's gender and educational attainment.

Performance-based outcome measures to assess functionality in hospitalised patients with COPD exacerbations: a systematic review of the measurement properties. Eur Respir Rev 2023; 32:230013. [PMID: 37437913 DOI: 10.1183/16000617.0013-2023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Accepted: 05/12/2023] [Indexed: 07/14/2023] Open
Abstract
INTRODUCTION Hospitalised patients with exacerbations of COPD (ECOPD) may have physical and functional impairments that impact morbidity and readmission. Therefore, it is crucial to properly identify reduced functionality in these patients to support a personalised rehabilitation. The objective of this study is to summarise and compare the measurement properties of functionality performance-based outcome measures for hospitalised patients with ECOPD. METHODS A systematic review based on the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) was performed. The PubMed, Embase, PEDro and Cochrane databases were searched using terms related to functionality, hospitalised patients with ECOPD and measurement properties. Studies were selected and extracted by two researchers. The COSMIN Risk of Bias checklist was applied to assess the methodological quality of the studies and measurement property results were compared with the criteria for good measurement properties. Quality of evidence was graded using a modified Grades of Recommendation, Assessment, Development and Evaluation approach. RESULTS 13 studies were included with nine outcome measures, namely the 6-min pegboard ring test, the de Morton mobility index, the incremental shuttle walk test (ISWT), the 6-min walk test (6MWT), maximum inspiratory pressure (MIP), the Berg balance scale, 4-m gait speed, handgrip strength and the 6-min stepper test. Construct validity was rated as sufficient, except for the ISWT. Responsiveness, assessed only for MIP, was considered insufficient and measurement errors for the ISWT and 6MWT were insufficient, with a very low quality of evidence for all measurement properties. CONCLUSION Measurement properties of performance-based outcome measures to assess functionality in patients hospitalised with ECOPD are still scarce, with very low evidence supporting validity and a lack of evidence of responsiveness and reliability. Further studies are needed to address this topic and guide assertive and personalised management.

Abstract
The prevalence of chronic obstructive pulmonary disease (COPD) is increasing worldwide and is currently the third leading cause of death globally. The long-term inhalation of toxic substances, mainly cigarette smoke, deteriorates pulmonary function over time, resulting in the development of COPD in adulthood. Periodontal disease is an inflammatory condition that affects most adults and is caused by the bacteria within dental plaque. These bacteria dissolve the gums around the teeth and the bone that supports them, ultimately leading to tooth loss. Periodontal disease and COPD share common risk factors, such as aging and smoking. Other similarities include local chronic inflammation and links with the onset and progression of systemic diseases such as ischemic heart disease and diabetes mellitus. Understanding whether interventions for periodontal disease improve the disease trajectory of COPD (and vice versa) is important, given our rapidly aging society. This review focuses on the putative relationship between COPD and periodontal disease while exploring current evidence and future research directions.

Abstract
BACKGROUND Nalmefene is an opioid system modulator with antagonist activity at the μ and δ receptors and partial agonist activity at the κ receptor. Previous studies have suggested that nalmefene could improve respiratory function in patients with chronic obstructive pulmonary disease (COPD). However, there is no comprehensive systematic review published regarding the clinical efficacy of nalmefene. METHODS We explored the following electronic bibliographic databases: EMBASE, Web of Science, PubMed, Wanfang, and Chinese national knowledge infrastructure. To collect data from randomized controlled trials on the therapy of COPD coupled with type II respiratory failure and nalmefene + noninvasive ventilator treatment. The retrieved articles were screened to determine the final inclusion criteria and to extract relevant data, such as the clinical efficacy rate, pulmonary function, blood gas analysis, and adverse reactions. In our study, we used relative risk and weighted mean deviation, as well as a 95% confidence interval for describing nalmefene effectiveness and safety while treating COPD with type II respiratory failure. RESULTS The outcomes of the meta-analysis demonstrated that the clinical efficacy rate of the nalmefene + noninvasive ventilation group was higher than that of the naloxone + noninvasive ventilation and noninvasive ventilation groups. Moreover, the improvement indices of pH value, partial pressure and saturation of blood oxygen, partial pressure of carbon dioxide, and pulmonary function of the nalmefene + noninvasive ventilation group were better than those of the noninvasive ventilation group, and there was no increase in the occurrence of adverse drug reactions. CONCLUSION Nalmefene combined with noninvasive ventilation can significantly improve the blood gas index and lung function in patients with COPD combined with type II respiratory failure.

Abstract
Background The most important problem of chronic obstructive pulmonary disease (COPD) patients is acute exacerbation. Researching this experience and examining its relationship with death is extremely important in patient care. Methods This study was conducted to reveal the experiences of individuals with a history of acute exacerbations of chronic obstructive pulmonary disease (AECOPDs) and their thoughts on death by qualitative empirical research. The study was conducted in a pulmonology clinic between July and September 2022. In-depth face-to-face interviews were conducted with patients in their rooms using a semi-structured form created specifically for the study and used as a data collection tool. With patient consent, interviews were recorded and documented. During the data analysis phase, the Colaizzi method was used. The study was presented in accordance with the Consolidated Criteria for Reporting Qualitative Research (COREQ) checklist for qualitative research. Results The study was completed with 15 patients. A total of 13 of the patients were male and the mean age was 65 years. Patient statements were coded after the interviews and collected under 11 sub-themes. These sub-themes were categorized under the following main themes: recognizing AECOPDs, AECOPD instant experiences, post-AECOPD, and thoughts on death. Conclusion Patients were able to recognize the symptoms of an AECOPD, that the severity of the symptoms increased during the exacerbation, that they felt regret or anxiety about re-exacerbation, and that all of these factors contributed to their fear of death.

Abstract
Background GOLD 2023 defines an exacerbation of COPD (ECOPD) by a deterioration of breathlessness at rest (BaR), mucus and cough. The severity of an ECOPD is determined by the degree of BaR, ranging from 0 to 10. However, it is not known which symptom is the most important one to detect early of an ECOPD, and which symptom that predicts future ECOPDs best. Thus, the purpose of the present study was to find out which symptom is the most important one to monitor. Methods We analysed data on COPD symptoms from the telehealth study The eHealth Diary. Frequent exacerbators (n = 27) were asked to daily monitor BaR and breathlessness at physical activity (BaPA), mucus and cough, employing a digital pen and symptom scales (0-10). Twenty-seven patients with 105 ECOPDs were analysed. The association between symptom development and the occurrence of exacerbations was evaluated using the Andersen-Gill formulation of the Cox proportional hazards model for the analysis of recurrent time-to-event data with time-varying predictors. Results According to the criteria proposed by GOLD 2023, 42% ECOPDs were mild, 48% were moderate and 5% were severe, while 6% were undefinable. Mucus and cough improved over study time, while BaR and BaPA deteriorated. Mucus appeared earliest, which was the most prominent feature of the average exacerbation, and worsening of mucus increased the risk for a future ECOPD. There was a 58% increase in the risk of exacerbation per unit increase in mucus score. Conclusion This study suggests that mucus worsening is the most important COPD symptom to monitor to detect ECOPDs early and to predict future risk för ECOPDs. In the present study, we also noticed a pronounced difference between GOLD 2022 and 2023. Hence, GOLD 2023 defined the ECOPD severity much lower than GOLD 2022 did.

Abstract
Purpose Chronic obstructive pulmonary disease (COPD) is characterized by high morbidity and mortality, with a considerable consumption of healthcare resources (HRU). This study aims to obtain real world evidence regarding the consequences of COPD exacerbations and to provide updated data on the burden of this disease and its treatment. Patients and Methods A retrospective study in seven Spanish regions was conducted among COPD patients diagnosed between 1/01/2010 and 31/12/2017. The index date was the diagnosis of COPD and patients were followed until lost to follow-up, death or end of the study, whichever occurred first. Patients were classified by patient pattern (incident or prevalent), type and severity of exacerbations, and treatments prescribed. Demographic and clinical characteristics were evaluated, together with the incidence of exacerbations, comorbidities, and the use of HRU, during the baseline (12 months before the index date) and the follow-up periods by incident/prevalent and treatment prescribed. Mortality rate was also measured. Results The study included 34,557 patients with a mean age of 70 years (standard deviation: 12). The most frequent comorbidities were diabetes, osteoporosis, and anxiety. Most patients received inhaled corticosteroids (ICS) with long-acting beta agonists (LABA), or long-acting muscarinic agonists (LAMA), followed by LABA with LAMA. Incident patients (N=8229; 23.8%) had fewer exacerbations than prevalent patients (N=26328; 76.2%), 0.3 vs 1.2 exacerbations per 100 patient-years. All treatment patterns present a substantial disease burden, which seems to increase with the evolution of the disease (ie moving from initial treatments to combination therapies). The overall mortality rate was 40.2 deaths/1000 patient-years. General practitioner visits and tests were the HRU most frequently required. The frequency and severity of exacerbations positively correlated with the use of HRU. Conclusion Despite receiving treatment, patients with COPD suffer a considerable burden mainly due to exacerbations and comorbidities, which require a substantial use of HRU.

Abstract
The role of pulmonary free fatty acid receptor 4 (FFAR4) is not fully elucidated and we aimed to clarify the impact of FFAR4 on the pulmonary immune response and return to homeostasis. We employed a known high-risk human pulmonary immunogenic exposure to extracts of dust from swine confinement facilities (DE). WT and Ffar4-null mice were repetitively exposed to DE via intranasal instillation and supplemented with docosahexaenoic acid (DHA) by oral gavage. We sought to understand if previous findings of DHA-mediated attenuation of the DE-induced inflammatory response are FFAR4-dependent. We identified that DHA mediates anti-inflammatory effects independent of FFAR4 expression, and that DE-exposed mice lacking FFAR4 had reduced immune cells in the airways, epithelial dysplasia, and impaired pulmonary barrier integrity. Analysis of transcripts using an immunology gene expression panel revealed a role for FFAR4 in lungs related to innate immune initiation of inflammation, cytoprotection, and immune cell migration. Ultimately, the presence of FFAR4 in the lung may regulate cell survival and repair following immune injury, suggestive of potential therapeutic directions for pulmonary disease.

Abstract
INTRODUCTION Recent evidence suggests a high prevalence of undiagnosed chronic obstructive pulmonary disease (COPD). These individuals are at risk of exacerbations and delayed treatment. We analyzed an at-risk population for the prevalence of abnormal spirometry to provide clarity into who should undergo early spirometry. METHODS We analyzed data from the COPDGene study. Participants with ≥10 pack-years of smoking were included. Individuals with self-reported or physician-diagnosed COPD, asthma, chronic bronchitis, emphysema and/or were on inhalers were excluded. Parsimonious multivariable logistic regression models identified factors associated with abnormal spirometry, defined as either airflow obstruction (AFO) or preserved ratio impaired spirometry. Variables were selected for the final model using a stepwise backward variable elimination process which minimized Akaike information criterion (AIC). Similarly, during the 5-year follow-up period, we assessed factors associated with incident diagnosis of COPD. RESULTS Of 5055 individuals, 1064 (21%) had undiagnosed AFO. Age, pack-years, current smoking and a history of acute bronchitis were associated with AFO while body mass index, female sex, and Black race were inversely associated. Among 2800 participants with 5-year follow-up, 532 (19%) had an incident diagnosis of COPD. Associated risk factors included mMRC ≥2, chronic productive cough, respiratory exacerbations during the follow-up period, and abnormal spirometry. Age was inversely associated. CONCLUSIONS The prevalence of undiagnosed COPD is high in at-risk populations. We found multiple factors associated with undiagnosed COPD and incident diagnosis of COPD at follow up. These results can be used to identify those at risk for undiagnosed COPD to facilitate earlier diagnosis and treatment.

Abstract
Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of mortality in our environment and was usually considered to be confined to the lung territory. The latest studies suggest that it is a systemic disease whose most probable etiopathogenesis is a state of low-intensity chronic inflammation that worsens during exacerbations. And recent scientific evidence has highlighted that cardiovascular diseases are one of the main causes of hospitalization and mortality in these patients. This relationship must be understood considering that both systems, the pulmonary and the cardiovascular, are closely related constituting the cardiopulmonary axis. Therefore, the therapeutic approach to COPD should not only include the treatment of respiratory complications, but also the prevention and treatment of cardiovascular diseases, which are very common in these patients. In this sense, in the last years, studies have been carried out that analyze the effect of the different types of inhaled therapy on all-cause mortality and cardiovascular mortality in particular.

Abstract
Background In the InforMing the Pathway of COPD Treatment (IMPACT) trial, single-inhaler fluticasone furoate (FF) /umeclidinium (UMEC) /vilanterol (VI) significantly reduced severe exacerbation rates and all-cause mortality (ACM) risk versus UMEC/VI among patients with chronic obstructive pulmonary disease (COPD). This post hoc analysis aimed to define the risk of ACM during and following a moderate/severe exacerbation, and further determine the benefit-risk profile of FF/UMEC/VI versus FF/VI and UMEC/VI using a cardiopulmonary composite adverse event (AE) endpoint. Methods The 52-week, double-blind IMPACT trial randomized patients with symptomatic COPD and ≥1 exacerbation in the prior year 2:2:1 to once-daily FF/UMEC/VI 100/62.5/25mcg, FF/VI 100/25mcg, or UMEC/VI 62.5/25mcg. Post hoc endpoints included the risk of ACM during, 1-90 and 91-365 days post moderate or severe exacerbation and time-to-first cardiopulmonary composite event. Results Of the 10,355 patients included, 5034 (49%) experienced moderate/severe exacerbations. Risk of ACM was significantly increased during a severe exacerbation event compared with baseline (hazard ratio [HR]: 41.22 [95% confidence interval (CI) 26.49-64.15]; p<0.001) but not significantly different at 1-90 days post-severe exacerbation (HR: 2.13 [95% CI: 0.86-5.29]; p=0.102). Moderate exacerbations did not significantly increase the risk of ACM during or after an exacerbation. Cardiopulmonary composite events occurred in 647 (16%), 636 (15%), and 356 (17%) patients receiving FF/UMEC/VI, FF/VI, and UMEC/VI, respectively; FF/UMEC/VI significantly reduced cardiopulmonary composite event risk versus UMEC/VI by 16.5% (95% CI: 5.0-26.7; p=0.006). Conclusion Results confirm a substantial mortality risk during severe exacerbations, and an underlying CV risk. FF/UMEC/VI significantly reduced the risk of a composite cardiopulmonary AE versus UMEC/VI.

Abstract
INTRODUCTION Patients with overlap syndrome (OS), that is obstructive sleep apnea (OSA) and chronic obstructive pulmonary disease (COPD), are at increased risk of acute exacerbations related to COPD (AECOPD). We assessed the effect of CPAP compliance on AECOPD, symptoms and pulmonary function in OS patients. METHODS Consecutive OS patients underwent assessment at baseline and at 12 months under treatment with CPAP of: AECOPD and hospitalizations, COPD Assessment Test (CAT) and modified British Medical Research Council (mMRC) questionnaires, pulmonary function testing and 6-min walking test (6MWT). RESULTS In total, 59 patients (54 males) with OS were followed for 12 months and divided post hoc according to CPAP compliance into: group A with good (≥4 h CPAP use/night, n = 29) and group B with poor (<4 h CPAP use/night, n = 30) CPAP compliance. At 12 months, group A showed improvements in FEV1 (p = 0.024), total lung capacity (p = 0.024), RV/TLC (p = 0.003), 6MWT (p < 0.001) and CAT (p < 0.001). COPD exacerbations decreased in patients with good CPAP compliance from baseline to 12 months (17 before vs. 5 after, p = 0.001), but not in those with poor compliance (15 before vs. 15 after, p = 1). At multivariate regression analysis, COPD exacerbations were associated with poor CPAP compliance (β = 0.362, 95% CI: 0.075-0.649, p = 0.015). CONCLUSIONS When compared to poorly compliant patients, OS patients with good CPAP compliance had a lower number of AECOPD and showed improved lung function and COPD related symptoms.

Abstract
Objective Devices for Automated Oxygen Administration (AOA) have been developed to optimize the therapeutic benefit of oxygen supplementation. We aimed to investigate the effect of AOA on multidimensional aspects of dyspnea and as-needed consumption of opioids and benzodiazepines, as opposed to conventional oxygen therapy, in hospitalized patients with Acute Exacerbation of COPD (AECOPD). Method and Patients A multicenter randomized controlled trial across five respiratory wards in the Capital Region of Denmark. Patients admitted with AECOPD (n=157) were allocated 1:1 to either AOA (O2matic Ltd), a closed loop device automatically delivering oxygen according to the patient's peripheral oxygen saturation (SpO2), or conventional nurse-administered oxygen therapy. Oxygen flows and SpO2 levels were measured by the O2matic device in both groups, while dyspnea, anxiety, depression, and COPD symptoms were accessed by Patient Reported Outcomes. Results Of the 157 randomized patients, 127 had complete data for the intervention. The AOA reduced patients' perception of overall unpleasantness significantly on the Multidimensional Dyspnea Profile (MDP) with a difference in medians of -3 (p=0.003) between the intervention group (n=64) and the control group (n=63). The AOA also provided a significant between group difference in all single items within the sensory domain of the MDP (all p-values≤0.05) as well as in the Visual Analogue Scale - Dyspnea (VAS-D) within the past three days (p=0.013). All between group differences exceeded the Minimal Clinical Important Difference of the MDP and VAS-D, respectively. AOA did not seem to have an impact on the emotional response domain of the MDP, the COPD Assessment Test, the Hospital Anxiety and Depression Scale, or use of as-needed opioids and/or benzodiazepines (all p-values>0.05). Conclusion AOA reduces both breathing discomfort and physical perception of dyspnea in patients admitted with AECOPD but did not seem to impact the emotional status or other COPD symptoms.

Abstract
In chronic obstructive pulmonary disease (COPD), comorbidities and worse functional status predict worse outcomes, but how these predictors compare with regard to different outcomes is not well studied. We thus compared the role of cardiovascular comorbidities for mortality and exacerbations. Data from baseline and up to four follow-up visits of the COSYCONET cohort were used. Cox or Poisson regression was employed to determine the relationship of predictors to mortality or mean annual exacerbation rate, respectively. Predictors comprised major comorbidities (including cardiovascular disease), lung function (forced expiratory volume in 1 s [FEV1], diffusion capacity for carbon monoxide [TLCO]) and their changes over time, baseline symptoms, exacerbations, physical activity, and cardiovascular medication. Overall, 1817 patients were included. Chronic coronary artery disease (p = 0.005), hypertension (p = 0.044) and the annual decline in TLCO (p = 0.001), but not FEV1 decline, were predictors of mortality. In contrast, the annual decline of FEV1 (p = 0.019) but not that of TLCO or cardiovascular comorbidities were linked to annual exacerbation rate. In conclusion, the presence of chronic coronary artery disease and hypertension were predictors of increased mortality in COPD, but not of increased exacerbation risk. This emphasizes the need for broad diagnostic workup in COPD, including the assessment of cardiovascular comorbidity.Clinical Trials: NCT01245933.

Abstract
Introduction Patient perception of the burden of chronic bronchitis symptoms in chronic obstructive pulmonary disease (COPD) can be assessed using patient-reported outcome measures (PROMs). The Cough and Sputum Assessment Questionnaire (CASA-Q) was developed and tested for this purpose. This study reviewed the performance of the CASA-Q in published online studies and tested a novel approach to complement traditional methods of qualitative content validation. Methods A targeted literature search was performed to identify published clinical studies of COPD using the CASA-Q as an endpoint. The performance of the questionnaire was examined in relation to other study endpoints, including clinical and functional measurements and other PROMs. Assessment of the content validity of the CASA-Q was carried out by comparing the content and structure of the questionnaire with published qualitative patient data from previously conducted online social media listening (SML) and online bulletin board (OBB) studies. Results In the interventional clinical trials, CASA-Q change scores were consistent with study objectives and other endpoints, including FEV1 and other PROMs. Two observational studies showed cross-sectional correlations with other PROMs like the St.-George's Respiratory Questionnaire (SGRQ) and COPD assessment test (CAT) scores. Qualitative data from the SML and OBB patient studies were consistent with the content and structure of the CASA-Q, supporting the content validity of the measure. Conclusion Results suggest that the CASA-Q is appropriately responsive to changes in cough and sputum symptoms and clinical impact in trials of COPD. The mapping of qualitative findings from online SML and OBB studies to CASA-Q domains and items confirm the content validity of the instrument. These results suggest the CASA-Q can be a valuable tool for evaluating treatment effect in COPD trials.

Abstract
INTRODUCTION Frequent exacerbation phenotype of chronic obstructive pulmonary disease (COPD) represents a more concerning disease subgroup requiring better prevention and intervention, of which airway microbiome provides new perspective for further exploration. METHODS To investigate whether frequent exacerbators of COPD have distinguishable sputum microbiome during clinical stability, COPD patients at high disease grades with or without frequent exacerbation were recruited for sputum microbiome analysis. Sputum samples were collected during clinical stability and underwent 16S rRNA sequencing, which was then subjected for amplicon sequence variants (ASVs)-based microbiome analysis. RESULTS Our results revealed that compared with healthy controls and infrequent exacerbators, frequent COPD exacerbators have distinguishably dysbiotic sputum microbiome, as featured by fewer ASVs features, lower alpha diversity, distinct beta diversity patterns. Further taxonomic compositional analysis illustrated the structural distinctions between frequent COPD exacerbators and infrequent exacerbators at differential taxa levels and highlighted Stenotrephomonas due to its prominent elevation in frequent COPD exacerbators, providing a promising candidate for further exploration of microbiome biomarker. Moreover, we also demonstrated that frequent exacerbation phenotype is distinguishable from infrequent exacerbation phenotype with respect of functional implications. CONCLUSION Our study demonstrated the first positive correlation between the frequent exacerbation phenotype of COPD and the sputum microbiome during clinical stability in a single-center Chinese COPD cohort and provide potential diagnostic and therapeutic targets for further investigation.

Abstract
PURPOSE Our study aimed to compare the predictive value of the COPD Assessment Test (CAT) score at baseline and short-term change in CAT for future exacerbations in chronic obstructive pulmonary disease (COPD) patients. METHODS This was a multicentre prospective study. Patients with COPD were recruited into the study and followed up for one year. CAT score and exacerbation in the previous year were collected at baseline. Change in CAT was defined as CAT score changing between baseline and the 6-month follow-up. Exacerbation was recorded during the one-year follow-up from 0th to 12th month. RESULT A total of 536 patients were enrolled for final analysis. The mean baseline CAT score was 14.5 ± 6.6 and the median (IQR) change in CAT was -2 (8). On Cox regression analysis, baseline CAT score, change in CAT and history of exacerbation were independent risk factors for exacerbation in the one-year follow-up. Compared with the r value of correlation between baseline CAT score and frequency of exacerbations during the one-year follow-up (r = 0.286, p < .001), that correlation between the change in CAT and frequency of exacerbations during follow-up was higher (r = 0.421, p < .001). The receiver operating characteristic (ROC) curves showed that change in CAT had a better predictive capacity for future exacerbation than baseline CAT (0.789 versus 0.609, p = .001). The ROC showed that change in CAT also had a better predictive capacity for future exacerbation than exacerbation in the previous year (0.789 versus 0.689, p = .011). CONCLUSION The correlation between baseline CAT score and future exacerbation was weak, however, the correlation between change in CAT and future exacerbation was moderate. Change in CAT in the short term had a better predictive value for future exacerbations of COPD than baseline CAT and exacerbation in the previous year.

Effect of Influenza Vaccine on Prevention of Acute Attack of Chronic Airway Disease in Elderly Population. Vaccines (Basel) 2022; 10:vaccines10101750. [PMID: 36298615 PMCID: PMC9611550 DOI: 10.3390/vaccines10101750] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2022] [Revised: 10/12/2022] [Accepted: 10/17/2022] [Indexed: 11/17/2022] Open
Abstract
This study investigated the effect of influenza vaccination on prevention of acute attacks in elderly patients with chronic airway disease and provides evidence for the prevention and control strategy of chronic airway disease in the elderly population. A total of 348 elderly patients in Linquan County, Anhui Province, China, who were also in stationary phases of chronic airway disease and were vaccinated with either the tetravalent or trivalent influenza vaccine were selected. The number of patients with acute attacks, the number of outpatients with acute attacks, the number of outpatients, the number of inpatients, the total cost of patients, the cost of outpatients, the cost of hospitalization, and the length of hospitalization were collected before vaccination and after a one-year follow-up. There was no significant difference in age and sex ratio among the two vaccination groups. The ratios of acute attacks, outpatient visits, and hospitalizations and number of outpatient visits, number of hospitalizations, total medical expenses, outpatient expenses, and hospitalization expenses were significantly higher before vaccination than those after vaccination in both the trivalent-vaccination group and tetravalent-vaccination group. Additionally, there was no significant difference in the length of stay between before and after vaccination in either the trivalent-vaccination group or tetravalent-vaccination group. The protection effect between the trivalent-vaccination group and tetravalent-vaccination group was not significant. Influenza vaccination can effectively prevent the acute attack of chronic airway disease and delay the progress of chronic airway disease.

Effect of Recent Exacerbation History on the Efficacy of Once-Daily Single-Inhaler Fluticasone Furoate/Umeclidinium/Vilanterol Triple Therapy in Patients with Chronic Obstructive Pulmonary Disease in the FULFIL Trial. Int J Chron Obstruct Pulmon Dis 2022; 17:2043-2052. [PMID: 36072608 PMCID: PMC9443998 DOI: 10.2147/copd.s367701] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Accepted: 08/17/2022] [Indexed: 12/04/2022] Open
Abstract
Background In the FULFIL trial, once-daily single-inhaler triple therapy with fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) resulted in reduced moderate/severe exacerbation rates and conferred significant improvements in lung function and health status in patients with chronic obstructive pulmonary disease (COPD) versus twice-daily budesonide/formoterol (BUD/FOR) dual therapy. Methods FULFIL was a Phase III, randomized, double-blind, double-dummy, parallel-group study. Patients ≥40 years of age with symptomatic COPD were randomized 1:1 to FF/UMEC/VI 100/62.5/25 mcg or BUD/FOR 400/12 mcg. In this post hoc analysis, patients were categorized by exacerbation history in the year prior to study entry (≥1 moderate/severe exacerbation [recent exacerbation] versus no recent exacerbation). Endpoints included annual rate of on-treatment moderate/severe exacerbations up to Week 24, annual rate of on-treatment severe exacerbations up to Week 24, change from baseline in trough forced expiratory volume in 1 second at Week 24, and change from baseline in health status as measured by St George’s respiratory questionnaire total score at Week 24. Results Of the 1810 patients in the intent-to-treat population, 1180 (65%) had one or more moderate/severe exacerbation in the year prior to entry, while 630 (35%) patients did not. FF/UMEC/VI versus BUD/FOR significantly reduced moderate/severe exacerbation rates in the recent exacerbation subgroup (mean annualized rate: 0.19 vs 0.29; rate ratio [95% confidence interval [CI]]: 0.64: [0.45, 0.91]; p=0.014) and numerically reduced moderate/severe exacerbation rates in the no recent exacerbation subgroup (mean annualized rate: 0.29 vs 0.43; rate ratio [95% CI]: 0.67 [0.43, 1.04]; p=0.073). Severe exacerbation rates were numerically reduced with FF/UMEC/VI versus BUD/FOR treatment across both subgroups. FF/UMEC/VI conferred significant improvements in lung function and health status versus BUD/FOR, regardless of recent exacerbation history. Conclusion FF/UMEC/VI reduced moderate/severe and severe exacerbation rates and improved lung function and health status versus BUD/FOR in patients with symptomatic COPD, regardless of recent exacerbation history.

Int J Chron Obstruct Pulmon Dis 2022; 17:1827-1834. [PMID: 35983166 PMCID: PMC9379107 DOI: 10.2147/copd.s367062] [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: 03/19/2022] [Accepted: 07/21/2022] [Indexed: 11/30/2022] Open
Abstract
Purpose Dyspnea is a leading symptom of COPD that causes presentations in emergency departments or negatively impacts on them. Guideline-based inhalation therapies are intended to reduce dyspnea in COPD patients. This study analyzed how common guideline recommended inhalation therapy regimens are occurring in clinical practice among COPD patients presenting to emergency departments due to adverse drug reactions in polytherapy using data of the German ADRED database. Patients and Methods In total, 269 COPD cases were identified. In a further analysis, all cases were analyzed for documented GOLD stage and guideline-recommended inhalation therapy for COPD. Dyspnea and other symptoms identified during ED presentation were analyzed and compared between patients who did and did not receive the guideline’s recommended inhalation therapy. Results In this observation, 41% (n = 46) of all 112 cases with a documented COPD and GOLD stage received an underdosed therapy according to current guidelines. Dyspnea was the most common identified symptom (32%, n = 36) in this cohort and occurred more often in patients who received an underdosage of inhalation therapy (p < 0.01). Conclusion Patients with COPD presenting to ED with ADRs show a high rate of non-guideline-recommended inhalation therapy and present more often with dyspnea compared to those COPD patients who received an adequate dosing of inhalation therapy.

Deep Learning-Based Computed Tomography Features in Evaluating Early Screening and Risk Factors for Chronic Obstructive Pulmonary Disease. CONTRAST MEDIA & MOLECULAR IMAGING 2022; 2022:5951418. [PMID: 36051929 PMCID: PMC9410847 DOI: 10.1155/2022/5951418] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Revised: 07/06/2022] [Accepted: 07/09/2022] [Indexed: 11/18/2022]
Abstract
This research aimed to investigate the diagnostic effect of computed tomography (CT) images based on a deep learning double residual convolution neural network (DRCNN) model on chronic obstructive pulmonary disease (COPD) and the related risk factors for COPD. The questionnaire survey was conducted among 980 permanent residents aged ≥ 40 years old. Among them, 84 patients who were diagnosed with COPD and volunteered to participate in the experiment and 25 healthy people were selected as the research subjects, and all of them underwent CT imaging scans. At the same time, an image noise reduction model based on the DRCNN was proposed to process CT images. The results showed that 84 of 980 subjects were diagnosed with COPD, and the overall prevalence of COPD in this epidemiological survey was 8.57%. Multivariate logistic regression model analysis showed that the regression coefficients of COPD with age, family history of COPD, and smoking were 0.557, 0.513, and 0.717, respectively (P < 0.05). The diagnostic sensitivity, specificity, and accuracy of DRCNN-based CT for COPD were greatly superior to those of single CT and the difference was considerable (P < 0.05). In summary, advanced age, family history of COPD, and smoking were independent risk factors for COPD. CT based on the DRCNN model can improve the diagnostic accuracy of simple CT images for COPD and has good performance in the early screening of COPD.
