Inhaled Corticosteroids May Not Affect the Clinical Outcomes of Pneumonia in Patients with Chronic Obstructive Pulmonary Disease. Tuberc Respir Dis (Seoul) 2024; 87:319-328. [PMID: 38369876 PMCID: PMC11222099 DOI: 10.4046/trd.2023.0176] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2023] [Revised: 02/05/2024] [Accepted: 02/17/2024] [Indexed: 02/20/2024] Open
Abstract
BACKGROUND Although inhaled corticosteroids (ICS) is reportedly associated with a higher risk of pneumonia in chronic obstructive pulmonary disease (COPD), the clinical implications of ICS have not been sufficiently verified to determine their effect on the prognosis of pneumonia. METHODS The electronic health records of patients hospitalized for pneumonia with underlying COPD were retrospectively reviewed. Pneumonia was confirmed using chest radiography or computed tomography. The clinical outcomes of pneumonia in patients with COPD who received ICS and those who received long-acting bronchodilators other than ICS were compared. RESULTS Among the 255 hospitalized patients, 89 met the inclusion criteria. The numbers of ICS and non-ICS users were 46 and 43, respectively. The CURB-65 (confusion, uremia, respiratory rate, blood pressure, age ≥65 years) scores at the initial presentation of pneumonia were comparable between the two groups. The proportions of patients with multilobar infiltration, pleural effusion, and complicated pneumonia in the radiological studies did not vary between the two groups. Additionally, the defervescence time, proportion of mechanical ventilation, intensive care unit admission, length of hospital stays, and mortality rate at 30 and 90 days were not significantly different between the two groups. ICS use and blood eosinophils count were not associated with all pneumonia outcomes and mortality in multivariate analyses. CONCLUSION The clinical outcomes of pneumonia following ICS use in patients with COPD did not differ from those in patients treated without ICS. Thus, ICS may not contribute to the severity and outcomes of pneumonia in patients with COPD.

Abstract
INTRODUCTION Despite the proven benefits of inhaled corticosteroid (ICS)-containing triple therapy for chronic obstructive pulmonary disease (COPD), clinicians limit patient exposure to ICS due to the risk of pneumonia. However, there are multiple factors associated with the risk of pneumonia in patients with COPD. This post hoc analysis of IMPACT trial data aims to set the risks associated with ICS into a context of specific patient-related factors that contribute to the risk of pneumonia. 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 fluticasone furoate (FF)/umeclidinium (UMEC)/vilanterol (VI), FF/VI or UMEC/VI. Annual rate of on-treatment pneumonias in the intent-to-treat population associated with age, body mass index (BMI), percent predicted forced expiratory volume in 1 s (FEV1) and blood eosinophil count (BEC) was evaluated. RESULTS This analysis revealed that the annual rate of pneumonia showed the lowest risk at the age of 50 years. The 95% confidence intervals (CI) between ICS-containing and non-ICS containing treatments diverged in ages > 63 years, suggesting a significantly increased ICS-related risk in older patients. In contrast, the annual rate of pneumonia rose in both groups below BMI of 22.5 kg/m2, but above that, there was no relationship to pneumonia rate and no differential effect between the two groups. The relationship between BEC and pneumonia was flat up to > 300/µL cells with ICS-containing treatment and then rose. In contrast, the rate of pneumonia with non-ICS containing treatment appeared to increase at a lower level of BEC (~ 200/µL). CONCLUSIONS There was little evidence of a differential effect of older age, lower BMI, lower FEV1 and BEC on the pneumonia rate between ICS-containing and non-ICS containing treatments. This analysis points to the need for a balanced approach to risk versus benefit in the use of ICS-containing treatments in COPD. CLINICAL TRIAL REGISTRATION IMPACT ClinicalTrials.gov number, NCT02164513.

Bufei Yishen formula protects the airway epithelial barrier and ameliorates COPD by enhancing autophagy through the Sirt1/AMPK/Foxo3 signaling pathway. Chin Med 2024; 19:32. [PMID: 38413976 PMCID: PMC10900682 DOI: 10.1186/s13020-024-00905-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2023] [Accepted: 02/17/2024] [Indexed: 02/29/2024] Open
Abstract
OBJECT Bufei Yishen formula (BYF), a traditional Chinese medicine alleviates COPD symptoms and suppresses airway epithelial inflammation. In this study, we determined whether BYF protects the airway epithelial barrier from destruction in COPD rats. METHODS The protective effects of BYF on the airway epithelial barrier were examined in a rat COPD model. BEAS-2B epithelial cells were exposed to cigarette smoke extract (CSE) to determine the effect of BYF on epithelial barrier function. Transcriptomic and network analyses were conducted to identify the protective mechanisms. RESULTS Oral BYF reduced the severity of COPD in rats by suppressing the decline in lung function, pathological changes, inflammation, and protected airway epithelial barrier function by upregulating apical junction proteins, including occludin (OCLN), zonula occludens (ZO)-1, and E-cadherin (E-cad). BYF treatment reduced epithelial permeability, and increased TEER as well as the apical junction proteins, OCLN, ZO-1, and E-cad in BEAS-2B cells exposed to CSE. Furthermore, 58 compounds identified in BYF were used to predict 421 potential targets. In addition, the expression of 572 differentially expressed genes (DEGs) was identified in CSE-exposed BEAS-2B cells. A network analysis of the 421 targets and 572 DEGs revealed that BYF regulates multiple pathways, of which the Sirt1, AMPK, Foxo3, and autophagy pathways may be the most important with respect to protective mechanisms. Moreover, in vitro experiments confirmed that nobiletin, one of the active compounds in BYF, increased apical junction protein levels, including OCLN, ZO-1, and E-cad. It also increased LC3B and phosphorylated AMPK levels and decreased the phosphorylation of FoxO3a. CONCLUSIONS BYF protects the airway epithelial barrier in COPD by enhancing autophagy through regulation of the SIRT1/AMPK/FOXO3 signaling pathway.

Abstract
Chronic obstructive pulmonary disease (COPD) is one of the major causes of disability and death. Maintenance use of inhaled bronchodilator(s) is the cornerstone of COPD pharmacological therapy, but inhaled corticosteroids (ICSs) are also commonly used. This narrative paper reviews the role of ICSs as maintenance treatment in combination with bronchodilators, usually in a single inhaler, in stable COPD subjects. The guidelines strongly recommend the addition of an ICS in COPD subjects with a history of concomitant asthma or as a step-up on the top of dual bronchodilators in the presence of hospitalization for exacerbation or at least two moderate exacerbations per year plus high blood eosinophil counts (≥300/mcl). This indication would only involve some COPD subjects. In contrast, in real life, triple inhaled therapy is largely used in COPD, independently of symptoms and in the presence of exacerbations. We will discuss the results of recent randomized controlled trials that found reduced all-cause mortality with triple inhaled therapy compared with dual inhaled long-acting bronchodilator therapy. ICS use is frequently associated with common local adverse events, such as dysphonia, oral candidiasis, and increased risk of pneumonia. Other side effects, such as systemic toxicity and unfavorable changes in the lung microbiome, are suspected mainly at higher doses of ICS in elderly COPD subjects with comorbidities, even if not fully demonstrated. We conclude that, contrary to real life, the use of ICS should be carefully evaluated in stable COPD patients.

Pragmat Obs Res 2024; 15:1-16. [PMID: 38274639 PMCID: PMC10807314 DOI: 10.2147/por.s438031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Accepted: 12/28/2023] [Indexed: 01/27/2024] Open
Abstract
Background Combined ICS and long-acting bronchodilators (LABD) more effectively reduce COPD exacerbations than LABD therapy alone. Corticosteroid-related adverse effects, including pneumonia, limit ICS use. Previous data suggest this risk is lower for extrafine beclometasone (ef-BDP). We compared pneumonia risk among new users of fixed dose ICS/LABD formulations containing ef-BDP, versus patients initiating LABD without any ICS. Methods A propensity-matched historical cohort study design used data from OPCRD. COPD patients with ≥1 year of continuous data who initiated LABD or ICS/LABD formulations containing ef-BDP were matched. Primary outcome was time to pneumonia event, as treated, using either sensitive (physician diagnosed) or specific (physician diagnosed and x-ray or hospital admission confirmed) definitions, with non-inferiority boundary of 15%. Results 23,898 COPD patients were matched, who were 68±11 years, 54.3% male and 56% current-smokers, while 43% were former-smokers. Initiation of ef-BDP/LABD was not associated with an increased risk of pneumonia versus LABD, for either a sensitive 0.89 (0.78-1.02), P = 0.08 or a specific 0.91 (0.78-1.05), P = 0.18 definition of pneumonia. The probability of remaining pneumonia free 1-year after ef-BDP/LABD was 98.4%, which was comparable to LABD at 97.7%, and was sustained up to 6 years of observation; non-inferiority criterion was met for both definitions. Initiation of ef-BDP/LABD was also associated with a reduced risk of developing LRTIs in the propensity matched cohort. Conclusion Risk of pneumonia when using ICS for the management of COPD reported in several randomised controlled trials may not be relevant with ef-BDP in a diverse real-world clinical population.

The safety and efficacy of Chinese herbal medicine for pneumonia prevention in high-risk elder residents in the nursing home: A randomized, double-blind clinical trial. JOURNAL OF ETHNOPHARMACOLOGY 2024; 318:117017. [PMID: 37562462 DOI: 10.1016/j.jep.2023.117017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Revised: 06/27/2023] [Accepted: 08/07/2023] [Indexed: 08/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Nursing home-associated pneumonia (NHAP) is a common type of infection among long-term care residents. Moreover, the mortality of NHAP is also higher than community-acquired pneumonia (CAP). In traditional Chinese medicine (TCM), the decoctions of Banxia Houpo Tang (BHT) and Ding Chuan Tang (DCT) are two formulas supporting the lungs' natural defense systems, helps to expel mucus and promote detoxification. AIM OF THE STUDY We designed a concentrated Chinese herbal extract formula called BDT1, that combines the compounds of BHT and DCT. In this study, we evaluated the safety and efficacy of BDT1 for NHAP prevention in high-risk older residents in the nursing home. MATERIALS AND METHODS In this randomized, double-blind, placebo-controlled trial, 160 participants aged over 65 years old living in the nursing home were randomly assigned 1:1 to the BDT1 and placebo group. Besides regular medicine, participants received either BDT1 or a placebo for 12 consecutive weeks. The primary outcome was the hospitalization rate for pneumonia in the intervention period and half-year follow-up. The microscopic examination of Gram-stained sputum was also evaluated before and after the trial. Data were analyzed by using the Chi-square test and Wilcoxon Signed Ranks Test with SPSS. RESULTS A total of 160 participants were enrolled into two study groups in this study, which was completed with 143 participants analyzed, including 70 subjects in the BDT1 group and 73 subjects in the placebo group. After the 12-week medical treatment, the hospitalization rate for pneumonia was 10.0% and 34.2% in the BDT1 and placebo group respectively. The risk of pneumonia in half a year was lower in the BDT1 group (adjusted hazard ratio = 0.422, 95% CI = 0.226-0.791). Compared to the placebo group, the level of Gram-negative bacilli in the BDT1 group is significantly declined in sputum samples (p < 0.05). CONCLUSION In conclusion, the cumulative incidence of pneumonia and related-hospitalization rates declined significantly after 12-weeks of BDT1 treatment. Besides, Chinese herbal medicine BDT1 is a safe therapy without hepatotoxicity or nephrotoxicity.

Maintenance of airway epithelial barrier integrity via the inhibition of AHR/EGFR activation ameliorates chronic obstructive pulmonary disease using effective-component combination. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 118:154980. [PMID: 37499344 DOI: 10.1016/j.phymed.2023.154980] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 07/01/2023] [Accepted: 07/15/2023] [Indexed: 07/29/2023]
Abstract
BACKGROUND Airway epithelial barrier dysfunction is highly related to the pathogenesis of chronic obstructive pulmonary disease (COPD). Effective-component combination (ECC) derived from Bufei Yishen formula (BYF) is an effective treatment regimen for patients with COPD and has previously been found to attenuate COPD and airway epithelial inflammation in rats. PURPOSE To determine the mechanism underlying the protective effects of ECC-BYF against the disruption of the airway epithelial barrier in COPD. METHODS The protective effects of ECC-BYF on the airway epithelial barrier were investigated in a rat COPD model. BEAS-2B epithelial cells were stimulated with cigarette smoke extract (CSE) to determine the direct effects of ECC-BYF on epithelial barrier function and aryl hydrocarbon receptor (AHR)/ epidermal growth factor receptor (EGFR) signaling. RESULTS The results revealed that ECC-BYF attenuated COPD in rats and maintained the airway epithelial barrier by upregulating the expression of apical junction proteins, including occludin (OCC), zonula occludens (ZO)-1, and E-cadherin (E-cad). In BEAS-2B cells, ECC-BYF decreased permeability, increased transepithelial electrical resistance, and prevented the decrease in OCC, ZO-1, and E-cad expression induced by CSE exposure. In addition, transcriptomics and network analysis revealed that the protective effects of ECC-BYF may be related to multiple signaling pathways, including ErbB, AHR, and PI3K-Akt-mTOR pathways. ECC-BYF treatment suppressed the protein levels of p-EGFR and p-ERK1/2 and mRNA levels of CYP1A1 in CSE-exposed BEAS-2B cells as well as the protein levels of p-EGFR, p-ERK1/2, and CYP1A1 in the lungs of rats with COPD. In BEAS-2B cells, the AHR agonist FICZ weakened the protective effect of ECC-BYF on the epithelial barrier by suppressing the increase in ZO-1 and OCC expression induced by ECC-BYF and preventing the inhibitory effects of ECC-BYF on EGFR phosphorylation. CONCLUSIONS This is the first study to demonstrate the protective effect of ECC-BYF on airway epithelial barrier function. The underlying mechanism may be associated with the suppression of the AHR/EGFR pathway to promote apical junction protein adhesion.

The use of inhaled corticosteroids (ICS) for the maintenance of bronchodilator treatment in patients with chronic obstructive pulmonary disease (COPD) is controversial. While some patients achieve clinical benefits, such as fewer exacerbations and improved symptoms, others do not, and some experience undesired side effects, such as pneumonia. Thus, we reviewed the evidence related to predictors of ICS therapy treatment response in patients with COPD. The first priority clinical markers when considering the efficacy of ICS are type 2 inflammatory biomarkers, followed by a history of suspected asthma and recurrent exacerbations. It is also necessary to consider any potential infection risk associated with ICS, and several risk factors for pneumonia when using ICS have been clarified in recent years. In this article, based on the evidence supporting the selection of ICS for COPD, we propose an ICS composite that can be added to the COPD (ICO) chart for use in clinical practice. The chart divided the type 2 biomarkers into three ranges and provided recommendations (recommend, consider, and against) by combining the history of suspected asthma, history of exacerbations, and risk of infection.

A Proposal to Differentiate ACO, Asthma and COPD in Vietnam. J Pers Med 2022; 13:jpm13010078. [PMID: 36675738 PMCID: PMC9863084 DOI: 10.3390/jpm13010078] [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: 11/15/2022] [Revised: 12/26/2022] [Accepted: 12/27/2022] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND In low- and middle-income countries, such as Vietnam, the population is exposed to multiple risks, leading to frequent allergic asthma, COPD and their overlap (ACO). We aimed to differentiate asthma and COPD, so that recommended treatments can be applied. METHODS We hypothesized that during life, the cumulative exposure to noxious particles increases the relative prevalence of COPD, while due to immuno-senescence, the prevalence of allergic asthma decreases with age. Among 568 patients with chronic respiratory symptoms, five phenotypes were defined, based on responsiveness to a bronchodilator (BD), diffusion capacity and cumulative smoking. Then the relative prevalence of each phenotype was related with age. RESULTS the smoker BD irreversible patients were considered "COPD", while the full BD responders and non-smoking BD incomplete responders were "asthmatics". The other patients were ACO, distributed as "like-COPD" or "like-asthma", based on decreased or normal diffusion capacity. The relative prevalence of asthma, COPD and ACO were 26, 42 and 32% (18% "like-asthma", 14% "like-COPD"). CONCLUSION Vietnamese patients with chronic respiratory symptoms were considered as falling into asthma or COPD groups, based on cumulative smoking, spirometry with reversibility and diffusion capacity. The relative prevalence of asthma and COPD were 44 and 56%, respectively, most of which did not require corticosteroids.

Abstract
OBJECTIVES International guidelines only advocate the use of inhaled corticosteroids (ICSs) in patients with chronic obstructive pulmonary disease (COPD) experiencing recurring exacerbations and eosinophilic inflammation. However, ICSs are commonly used in patients with COPD and without exacerbations and signs of eosinophilic inflammation, thus possibly increasing the risk of hospitalization for pneumonia. Thus, we aimed to determine the risk of hospitalization for pneumonia associated with increasing cumulated ICS doses among patients with COPD to establish whether there is dose dependency. METHODS A retrospective cohort study included all patients with COPD treated at a respiratory outpatient clinic in Denmark. The patients were divided into four groups based on their average daily ICS exposure. The dose-response relationship was investigated using a multivariable Cox proportional hazard regression analysis. RESULTS In total, 52 100 patients were included, who were divided into the no-use (n = 15 755), low-dose (n = 12 050), moderate-dose (n = 12 488), and high-dose (n = 11 807) groups. ICS use was strongly associated with hospitalization for pneumonia (hazard ratio [HR], 1.3; CI, 1.2-1.3) (ICS vs. no ICS). The risk of hospitalization for pneumonia increased with every dosing group step: low dose: HR, 1.1 (CI, 1.0-1.2); moderate dose: HR, 1.2 (CI, 1.1-1.3), and high dose: HR, 1.5 (CI, 1.4-1.6); "no use" was the reference. Sensitivity analyses confirmed these findings. CONCLUSIONS In the dose-response relationship analysis, ICS dose were associated with a substantially increased risk of hospitalization for pneumonia of up to 50%. Our data support that ICSs should be administered at the lowest possible dose and only to patients with COPD who have a documented need.

Abstract
Chronic obstructive pulmonary disease (COPD) is a global public health burden that stands out as a leading cause of mortality around the world, especially in less developed countries. COPD treatment should be centered on the individual necessities of each patient, integrating pharmacological therapy, immunization, nutritional support, pulmonary rehabilitation and control of comorbidities. Combining a long-acting antimuscarinic (LAMA) with a long-acting beta2-agonist (LABA) bronchodilator has proven to be more effective than monotherapy with LABA or LAMA, in terms of the functional improvement of forced expiratory volume (FEV1), symptoms and life quality and may be helpful in patients with progressive dyspnea. The eosinophil blood count is a simple biomarker that could guide personalized treatment strategies by identifying patients with greater clinical benefits of inhaled corticosteroid (ICS) treatment. However, one critical concern is the increased risk of pneumonia in individuals treated with ICS.

Abstract
Chronic obstructive pulmonary disease (COPD) is associated with a poor prognosis in patients with non-small cell lung cancer (NSCLC). However, the impact of COPD treatment on the survival of patients with advanced NSCLC remains uncertain. We retrospectively investigated COPD patients among patients newly diagnosed with advanced NSCLC between September 2005 and August 2019 at a university hospital. The clinical characteristics, lung function, and survival outcomes were analyzed and compared between patients who did and did not receive COPD treatment. Among 221 patients with advanced NSCLC and COPD, 124 patients received treatment for COPD and 97 patients did not receive treatment for COPD. Forced expiratory volume in 1 s (FEV1) % predicted value was greater in the no-treatment group than in the COPD treatment group (p < 0.001). The median overall survival (OS) of the treatment group was 10.7 months, while that of the no-treatment group was 8.7 months (p = 0.007). In the multivariate analysis, COPD treatment was independently associated with improved OS (hazard ratio 0.71, 95% confidence interval 0.53−0.95, and p = 0.021). COPD treatment was associated with improved OS in patients with advanced NSCLC and COPD. Therefore, pretreatment spirometry and maximal treatment for COPD may offer a chance of optimal management for patients with advanced NSCLC.

Abstract
Background and objective Chronic obstructive pulmonary disease (COPD) patients with a body mass index (BMI) < 25 kg/m2 are prone to develop adverse event of pharmacological treatment for frequent exacerbation. As chronic bronchitis (CB) is one of the strong risk factors of exacerbation, we investigated the associations between BMI and COPD exacerbations in patients with CB. Methods Patients with COPD were included from the Korean COPD Subgroup Study (KOCOSS), a multicenter observational cohort study. CB was defined using the St. George’s Respiratory Questionnaire and the participants were categorized according to BMI cut-off of 25 kg/m2. Exacerbations during a 1-year follow-up were compared among four groups: non-CB with BMI ≥ 25 kg/m2, non-CB with BMI < 25 kg/m2, CB with BMI ≥ 25 kg/m2, and CB with BMI < 25 kg/m2. Results Among the 1264 patients with COPD, 451 (35.7%) had CB and 353 (27.9%) had both CB and BMI < 25 kg/m2. The COPD exacerbation risk increased across the non-CB with BMI < 25 kg/m2, CB with BMI ≥ 25 kg/m2, and CB with BMI < 25 kg/m2 groups (adjusted incidence rate ratio [95% confidence interval] 1.21 [0.89–1.62], 1.20 [0.77–1.88], and 1.41 [1.02–1.91], respectively, compared to the non-CB with BMI ≥ 25 kg/m2 group). Conclusions COPD patients having both CB and a BMI < 25 kg/m2 are at higher risk of exacerbations. Considering that a BMI < 25 kg/m2 often limits treatment options preventing exacerbations, modified guidelines might be needed for non-obese CB patients in Asia.

Abstract
Background Inhaled corticosteroids (ICS) afford therapeutic benefits in some COPD patients, but their widespread use is cautioned due to an increased risk of developing pneumonia. Subclass variations exist, and the risk profile differs for individual ICS. Formulation particle size has been identified as a potential effect modifier. The present study compared the risk of pneumonia among new COPD users of fixed-dose combination inhalers containing fine-particle fluticasone (fp-FDC-F) versus extrafine particle beclometasone (ef-FDC-BDP). Methods A propensity matched historical cohort study was conducted using data from the Optimum Patient Care Research Database. COPD patients aged ≥40 years with ≥1 year of continuous medical data who initiated fp-FDC-F or ef-FDC-BDP were compared. The primary outcome was time to pneumonia event, as treated, using either sensitive (physician diagnosed) or specific (physician diagnosed and x-ray or hospital admission confirmed) definitions. Results A total of 13,316 patients were matched. Initiation of fp-FDC-F (mean dosage furoate 99 µg; propionate 710 µg) was associated with an increased risk of pneumonia versus ef-FDC-BDP (mean beclometasone dose 395 µg), irrespective of definition (sensitive HR 1.38 95% CI 1.14–1.68; specific HR 1.31 95% CI 1.05–1.62). Conclusion In the current investigation, we found that in comparison to extrafine beclomethasone, commencing a formulation containing fluticasone is associated with an increased risk of developing pneumonia. These observations support the idea that not all ICS are equal in their adverse effects and subclass variations exist and should be carefully considered in the treatment choice.

Abstract
Although pharmacological treatment of COPD is codified in different guidelines and strategy documents, there is abundant evidence of discrepancy between what they suggest and what health professionals prescribe, especially in low-risk groups where there is widespread overprescription of triple therapy. It is therefore necessary to clarify when the use of triple therapy is indicated in COPD patients and when it is preferable to maintain treatment with dual bronchodilation. In this article, we discuss our views based on our experience and what is reported in the literature and try to give answers to these two questions. The evidence generated by pivotal RCTs supports the use of triple therapy in patients who present for the first time and have severe airway obstruction, are symptomatic, have had frequent moderate or severe exacerbations in the previous year, and have peripheral eosinophilia. However, it is difficult to determine whether step-up is useful in all other cases because the available data are quite conflicting. It is likely that the inconsistency in the information generated by the various available studies may explain the prescribing behaviour of many physicians who do not adhere to recommendations of guidelines and strategies. However, it is necessary to establish whether and when the addition of an ICS to the LAMA/LABA combination is effective, to determine whether triple therapy can induce an additional clinical benefit over dual bronchodilation, irrespective of a preventive effect on COPD exacerbations, to establish its value, and to examine whether cost differences can support the use of triple therapy over combined LAMA/LABA therapy in real life.

Abstract
Inhaled corticosteroids (ICS) have a class effect of increasing pneumonia risk in patients with COPD. However, pneumonia incidence varies widely across clinical trials of ICS use in COPD. This review clarifies methodological differences in defining and recording pneumonia events in these trials and discusses factors that could contribute to the varying pneumonia incidence. Literature searches and screening yielded 40 relevant references for inclusion. Methods used to capture pneumonia events in these studies included investigator-reported pneumonia adverse events, standardised list of signs or symptoms, radiographic confirmation of suspected cases and/or confirmation by an independent clinical end-point committee. In general, more stringent pneumonia diagnosis criteria led to lower reported pneumonia incidence rates. In addition, studies varied in design and population characteristics, including exacerbation history and lung function, factors that probably contribute to the varying pneumonia incidence. As such, cross-trial comparisons are problematic. A minimal set of standardised criteria for diagnosis and reporting of pneumonia should be used in COPD studies, as well as reporting of patients’ pneumonia history at baseline, to allow comparison of pneumonia rates between trials. Currently, within-trial comparison of ICS-containing versus non-ICS-containing treatments is the appropriate method to assess the influence of ICS on pneumonia incidence. Trials of ICS in COPD use varying methods of reporting pneumonia incidence, which influence the interpretation of results. A minimal set of standardised criteria for pneumonia diagnosis would allow comparison of pneumonia incidence between trials.https://bit.ly/3nbkdoL

Abstract
Chronic obstructive pulmonary disease (COPD) is a main cause of death due to interplaying factors, including comorbidities that interfere with symptoms and response to therapy. It is now admitted that COPD management should be based on clinical symptoms and health status and should consider the heterogeneity of patients' phenotypes and treatable traits. This precision medicine approach involves a regular assessment of the patient's status and of the expected benefits and risks of therapy. The cornerstone of COPD pharmacological therapy is inhaled long-acting bronchodilation. In patients with persistent or worsened symptoms, factors likely to interfere with treatment efficacy include the patient's non-adherence to therapy, treatment preference, inhaler misuse and/or comorbidities, which should be systematically investigated before escalation is considered. Several comorbidities are known to impact symptoms, physical and social activity and lung function. The possible long-term side-effects of inhaled corticosteroids contrasting with their over-prescription in COPD patients justify the regular assessment of their benefits and risks, and de-escalation under close monitoring after a sufficient period of stability is to be considered. While commonly used in clinical trials, the relevance of routine blood eosinophil counts to guide therapy adjustment is not fully clear. Patients' characteristics, which define phenotypes and treatable traits and thus guide therapy, often change during life, forming the basis of the concept of clinical trajectory. The application of individual trajectory-based management of COPD in clinical practice therefore implies that the benefit:risk ratio is regularly reviewed according to the evolution of the patient's traits over time to allow optimised therapy adjustments.

Abstract
INTRODUCTION Inhaled corticosteroids (ICS) are known to increase the risk of systemic and local adverse effects, especially with high doses and long-term use. Hence, considerable resources are invested to improve pharmacokinetic/pharmacodynamic (PK/PD) properties of ICS, effective delivery systems and novel combination therapies to enhance the risk-to-benefit ratio of ICS. AREAS COVERED There is an unmet need for new solutions to achieve optimal clinical outcomes with minimal dose of ICS. This paper gives an overview of novel treatment strategies regarding the safety of ICS therapy on the basis of the three most recent molecules introduced to our everyday clinical practice - ciclesonide, mometasone furoate, and fluticasone furoate. Advances in aerosol devices and new areas of inhalation therapy are also discussed. EXPERT OPINION Current progress in improving the risk-to-benefit ratio of ICS through dose and delivery probably established pathways for further developments. This applies both to the improvement of the PK/PD properties of ICS molecules but also includes technical aspects that lead to simplified applicability of the device with simultaneous optimal drug deposition in the lungs. Indubitably, the future of medicine lies not only in the development of new molecules but also in technology and digital revolution.

Abstract
OBJECTIVE To review the 2020 Global Initiative for Chronic Obstructive Lung Disease (GOLD) report recommendations and create an algorithm to assist clinicians in determining which chronic obstructive pulmonary disease (COPD) patients qualify for inhaled corticosteroid (ICS) de-escalation. Data Sources: A literature search of MEDLINE/PubMed from 2002 to August 2021 was conducted using the search terms inhaled corticosteroids, chronic obstructive pulmonary disease, and de-escalation and review of the reference lists of identified articles for pertinent citations. STUDY SELECTION AND DATA EXTRACTION Relevant studies and articles were included if they focused on the utilization of ICS in COPD. DATA SYNTHESIS The 2020 GOLD report only recommends triple therapy with ICS, long acting beta agonists, and long acting muscarinic antagonists for patients with frequent exacerbations, frequent hospitalizations, or elevated blood eosinophil counts. Despite this clear framework, patients are prescribed ICS without these characteristics. Available evidence suggests that these patients can be de-escalated from ICS therapy without concern for worsening lung function or exacerbations. Relevance to Patient Care and Clinical Practice: Patients with COPD may be experiencing more risk than benefit on ICS therapy. Clinicians should be knowledgeable on how to evaluate patient therapy for appropriateness and know how to safely deprescribe ICS given their limited efficacy in many COPD patients. CONCLUSION There remains no specific guidance on how to de-escalate patients off an ICS when the therapy is not indicated. Use of clinical evidence with stepwise algorithms can be models to approach de-escalation of ICS in patients with COPD.

Abstract
PURPOSE To assess if early multiple-inhaler triple therapy (MITT) initiation in patients with chronic obstructive pulmonary disease (COPD) reduces subsequent healthcare resource utilization (HCRU), direct medical costs, and acute exacerbations of COPD (AECOPDs). PATIENTS AND METHODS This retrospective, longitudinal cohort study used electronic health records and linked hospital administrative data in England. COPD patients with an AECOPD between July 2012 and May 2016 (index), and who subsequently started MITT within 180 days were eligible. Patients with an AECOPD 6 months prior to index were excluded. HCRU, direct healthcare costs, and AECOPDs were assessed in the following 24-month period for early (≤30 days) and delayed (31-180 days) MITT initiators. RESULTS A total of 934 patients were included in the analysis and categorized as early (n=367, 39%) or delayed (n=567, 61%) MITT initiators. Mean patient age was 68.5 years and 53.2% were male. A significantly higher proportion of delayed MITT initiators required ≥1 outpatient appointment (all-cause) compared with early MITT initiators (87% vs 79%; p=0.0016). A significantly higher proportion of delayed MITT initiators required ≥1 COPD‑related inpatient stay versus early MITT initiators (47% vs 40%; p=0.0262). Over the 24-month follow-up, mean all-cause and COPD-related total healthcare costs were significantly higher in delayed MITT initiators compared with early MITT initiators (all‑cause: £11,348 vs £8126; p=0.0011; COPD-related: £7307 vs £4535; p=0.0009). CONCLUSION Delayed initiation of multiple-inhaler triple therapy was associated with higher all-cause and COPD-related costs, suggesting that earlier initiation of triple therapy in COPD patients may help reduce the economic burden on the healthcare system.

Abstract
The Global Initiative for Chronic Obstructive Lung Disease 2021 Report recommends inhaled corticosteroid (ICS)-containing regimens as part of pharmacological treatment in patients with chronic obstructive lung disease (COPD) and frequent exacerbations, particularly with eosinophilic inflammation. However, real-world studies reveal overprescription of ICS in COPD, irrespective of disease presentation and inflammatory endotype, leading to increased risk of side effects, mainly respiratory infections. The optimal use of ICS in COPD therefore remains an area of intensive research, and additional biomarkers of benefit and risk are needed. Although the interplay between inflammation and infection in COPD is widely acknowledged, the role of the microbiome in shaping lower airway inflammation has only recently been explored. Next-generation sequencing has revealed that COPD disease progression and exacerbation frequency are associated with changes in the composition of the lung microbiome, and that the immunosuppressive effects of ICS can contribute to potentially deleterious airway microbiota changes by increasing bacterial load and the abundance of potentially pathogenic taxa such as Streptococcus and Haemophilus. Here, we explore the relationship between microbiome, inflammation, ICS use and disease phenotype. This relationship may inform the benefit:risk assessment of ICS use in patients with COPD and lead to more personalised pharmacological management.

Abstract
Inhaled corticosteroids (ICSs) are indicated for the prevention of exacerbations in COPD; however, a significant proportion of patients at low risk of exacerbations are treated with ICSs. We conducted a systematic review including a diversity of types of study designs and safety outcomes with the objective of describing the risk of adverse effects associated with the long-term use of ICSs in patients with COPD.A total of 90 references corresponding to 83 studies were included, including 26 randomised clinical trials (RCTs), 33 cohort studies, and 24 nested case-control (NCC) studies. Analysis of 19 RCTs showed that exposure to ICSs for ≥1 year increased the risk of pneumonia by 41% (risk ratio 1.41, 95% CI 1.23-1.61). Additionally, cohort and NCC studies showed an association between ICSs and risk of tuberculosis and mycobacterial disease. There was a strong association between ICS use and local disorders such as oral candidiasis and dysphonia. The association between ICSs and the risk of diabetes and fractures was less clear and appeared significant only at high doses of ICSs.Since most patients with COPD are elderly and with frequent comorbidities, an adequate risk-benefit balance is crucial for the indication of ICSs.

[PMID: 34154582 PMCID: PMC8218448 DOI: 10.1186/s12931-021-01777-x] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2021] [Accepted: 06/10/2021] [Indexed: 11/25/2022] Open
Abstract
Background Recently, the addition of inhaled corticosteroid (ICS) to long-acting muscarinic antagonist (LAMA) and long-acting beta-agonist (LABA) combination therapy has been recommended for patients with COPD who have severe symptoms and a history of exacerbations because it reduces the exacerbations. In addition, a reducing effect on mortality has been shown by this treatment. However, the evidence is mainly based on one large randomized controlled trial IMPACT study, and it remains unclear whether the ICS add-on treatment is beneficial or not. Recently, a large new ETHOS trial has been performed to clarify the ICS add-on effects. Therefore, we conducted a systematic review and meta-analysis to evaluate the efficacy and safety including ETHOS trial. Methods We searched relevant randomized control trials (RCTs) and analyzed the exacerbations, quality of life (QOL), dyspnea symptom, lung function and adverse events including pneumonia and mortality, as the outcomes of interest. Results We identified a total of 6 RCTs in ICS add-on protocol (N = 13,579). ICS/LAMA/LABA treatment (triple therapy) significantly decreased the incidence of exacerbations (rate ratio 0.73, 95% CI 0.64–0.83) and improved the QOL score and trough FEV1 compared to LAMA/LABA. In addition, triple therapy significantly improved the dyspnea score (mean difference 0.33, 95% CI 0.18–0.48) and mortality (odds ratio 0.66, 95% CI 0.50–0.87). However, triple therapy showed a significantly higher incidence of pneumonia (odds ratio 1.52, 95% CI 1.16–2.00). In the ICS-withdrawal protocol including 2 RCTs, triple therapy also showed a significantly better QOL score and higher trough FEV1 than LAMA/LABA. Concerning the trough FEV1, QOL score and dyspnea score in both protocols, the differences were less than the minimal clinically important difference. Conclusion Triple therapy causes a higher incidence of pneumonia but is a more preferable treatment than LAMA/LABA due to the lower incidence of exacerbations, higher trough FEV1 and better QOL score. In addition, triple therapy is also superior to LABA/LAMA due to the lower mortality and better dyspnea score. However, these results should be only applied to patients with symptomatic moderate to severe COPD and a history of exacerbations. Clinical Trial Registration: PROSPERO; CRD42020191978.

Abstract
INTRODUCTION In the IMPACT trial, single-inhaler triple therapy fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) reduced moderate/severe exacerbation rates versus FF/VI or UMEC/VI dual therapy in patients with chronic obstructive pulmonary disease (COPD); however, pneumonia incidence was higher in FF-containing arms. As COPD is a growing problem in Asia, we compared the efficacy and safety of FF/UMEC/VI in Asia versus non-Asia regions. METHODS IMPACT was a double-blind, 52-week trial in symptomatic COPD patients with ≥ 1 moderate/severe exacerbation in the prior year. This pre-specified analysis evaluated the annual rate of moderate/severe exacerbations, change from baseline in trough forced expiratory volume in 1 s, and St George's Respiratory Questionnaire total score, mortality, and safety (including pneumonia) in Asia versus non-Asia regions. RESULTS The intent-to-treat population comprised 10,355 patients (Asia n = 1644 [16%]). Rate ratios (95% confidence intervals) for moderate/severe exacerbations with FF/UMEC/VI were 0.89 (0.76-1.05) versus FF/VI and 0.86 (0.71-1.04) versus UMEC/VI in Asia, and 0.84 (0.79-0.90) and 0.74 (0.68-0.80) in non-Asia. Efficacy of FF/UMEC/VI on other endpoints was similar in both regions. There was an increased incidence of investigator-reported pneumonia in patients in Asia (FF/UMEC/VI: 13%; FF/VI: 14%; UMEC/VI: 6%) compared with non-Asia (FF/UMEC/VI: 6%; FF/VI: 5%; UMEC/VI: 4%). The increased risk of pneumonia in patients in Asia was most marked in patients with lower body mass index, lower lung function, and taking inhaled corticosteroids. In post hoc analysis of adjudicated on-treatment all-cause mortality, probabilities of death were numerically lower in both regions with FF/UMEC/VI (Asia: 1.16%; non-Asia: 1.35%) and FF/VI (Asia: 1.77%; non-Asia: 1.21%) versus UMEC/VI (Asia: 1.91%; non-Asia: 2.23%). CONCLUSIONS FF/UMEC/VI provides similar benefits in COPD patients in Asia and non-Asia regions. Clinical benefits of treatment, including reduction in mortality risk, should be weighed against risk of pneumonia, taking account of all known risk factors.

Abstract
Rationale: In the IMPACT (Informing the Pathway of COPD Treatment) trial, single-inhaler fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) triple therapy reduced exacerbation risk versus FF/VI and UMEC/VI and mortality risk versus UMEC/VI. However, pneumonia incidence was higher in the inhaled corticosteroid (FF)-containing arms, raising questions about the relative benefit of exacerbation reduction compared with the increased risk of pneumonia.Objectives: Determine benefit-risk of the three treatments by evaluating time-to-first and rates of composite exacerbation or pneumonia outcomes.Methods: We evaluated time-to-first (prespecified) and rates (post hoc) of investigator-reported pneumonia, serious pneumonia leading to hospitalization or death, and the composite endpoints of 1) moderate (required antibiotics/corticosteroids)/severe (hospitalized) exacerbation or pneumonia and 2) severe exacerbation or serious (hospitalized) pneumonia. Analyses were repeated for radiographically confirmed pneumonia (post hoc).Results: Moderate/severe exacerbations occurred in 47%, 49%, and 50% of patients randomized to FF/UMEC/VI, FF/VI and UMEC/VI, and pneumonias in 8%, 7%, and 5%, respectively. FF/UMEC/VI reduced the risk of combined moderate/severe exacerbation or pneumonia (time-to-first) versus FF/VI (hazard ratio, 0.87 [95% confidence interval (CI), 0.82-0.92]) and UMEC/VI (0.87 [0.81-0.94]), as well as the risk of combined severe exacerbation or serious pneumonia versus UMEC/VI (0.83 [0.72-0.96]). FF/UMEC/VI reduced the rate of combined moderate/severe exacerbation or pneumonia (rate ratio, 0.78 [0.72-0.84]) and combined severe exacerbation or serious pneumonia (rate ratio, 0.76 [0.65-0.89]) versus UMEC/VI. Results were similar for radiographically confirmed pneumonia endpoints.Conclusions: Despite higher incidence of pneumonia in FF-containing arms, these composite exacerbation/pneumonia outcomes support a favorable benefit-risk profile of FF/UMEC/VI versus FF/VI and UMEC/VI in patients with symptomatic chronic obstructive pulmonary disease and a history of exacerbations.

Abstract
Pharmacological treatment for chronic obstructive pulmonary disease (COPD) aims to alleviate symptoms and reduce the future risk of events such as exacerbations, disease progression and death. The heterogeneity of COPD results in variable responses to pharmacological interventions. COPD treatment has evolved towards a precision medicine approach, integrating clinical and biomarker information in order to optimize treatment decisions for each individual. The evidence supporting the use of blood eosinophil counts to predict responses to inhaled corticosteroids (ICS) in COPD patients has led to the adoption of this biomarker for use in clinical practice. The development of novel double and triple inhaled combination treatments containing long-acting bronchodilators with or without ICS has involved some landmark randomized controlled trials in COPD patients. These studies have provided valuable evidence to direct the use of different classes of combination treatments. However, there are still some unresolved questions and debates. This review article describes the advances in the pharmacological treatment of COPD, particularly the personalization of treatment. The evidence base for current recommendations is discussed, and controversial issues are dissected.

Abstract
There is limited information about the initiation of triple therapy (TT) in patients with chronic obstructive pulmonary disease (COPD) in primary care. This was an observational, population-based study in patients identified from a primary care electronic medical records database in Catalonia from 2011 to 2015 aimed to identify the use of TT in patients with newly diagnosed COPD. A total of 69,668 newly diagnosed patients were identified of whom 11,524 (16.5%) initiated TT, of whom 8626 initiated TT at or immediately after COPD diagnosis. Among them, 72.3% were GOLD A/B, 14.6% were frequent exacerbators, and 7.1% had asthma-COPD overlap (ACO). Variables associated with TT initiation were: male sex, older age, previous exacerbations, ACO, a previous treatment regimen containing an inhaled corticosteroid, previous pneumonia, and history of lung cancer. A significant number of COPD patients in Primary Care initiated TT shortly after or even before an established COPD diagnosis.

Abstract
Randomized controlled trials (RCTs) are preferred by payers for health technology assessments and coverage decisions. However, the inclusion of a highly selective patient population and the rigorously controlled conditions in RCTs may not be reflective of real-world clinical practice. Real-world evidence (RWE) obtained from an analysis of real-world data (RWD) from observational studies can bridge gaps in evidence not addressed by RCTs and is thus valuable to public and private payers for decision-making. Through a broad literature search to obtain insights into payers' experience, we found that payers have concerns about real-world studies with respect to data quality, poor internal validity, potential bias, and lack of meaningful endpoints. However, they valued RWE to fill evidence gaps not addressed by RCTs, such as high-quality, real-world, long-term effectiveness and safety data; head-to-head drug comparisons; cost analyses for tiering formulary placement; medication use and adherence patterns; identification of relevant responder and non-responder patient subpopulations; and patient-reported outcomes (PROs). RWE can be used to assess clinically meaningful endpoints and gauge the impact of interventions on the quality of healthcare. Here, we review how payers use or can use RWD on the comparative effectiveness and safety of treatments, PROs, medication adherence and persistence, prescribing patterns, healthcare resource utilization, and patient characteristics and/or biomarkers associated with treatment response when making health technology assessments and payer coverage decisions across therapeutic areas.

Abstract
OBJECTIVES Chronic obstructive pulmonary disease (COPD) is becoming a leading cause of morbidity and mortality in China. In the IMPACT trial, fluticasone furoate[FF]/umeclidinium[UMEC]/vilanterol[VI] single-inhaler triple therapy demonstrated lower rates of moderate/severe exacerbations than dual therapy with FF/VI or UMEC/VI in patients with symptomatic COPD and a history of exacerbations. This analysis investigates the China cohort and its consistency with the overall ITT population. METHODS 10,355 patients were randomized 2:2:1 to once-daily FF/UMEC/VI 100/62.5/25 µg, FF/VI 100/25 µg, or UMEC/VI 62.5/25 µg for 52 weeks. Endpoints included: annual rates of exacerbations, time-to-first on-treatment moderate/severe exacerbation and change from baseline in trough forced expiratory volume in 1 s (FEV1) at Week-52. Clinical trial registration is NCT02164513 (CTT116855). RESULTS 535 patients (5.2%) were from China. Annual on-treatment moderate/severe exacerbation rate was 0.81 with FF/UMEC/VI versus 0.96 with FF/VI (rate ratio: 0.84; 95% confidence interval [CI]: 0.64, 1.11; p = .227) and 0.80 with UMEC/VI (rate ratio: 1.02; 95% CI: 0.72, 1.44; p = .929). Hazard ratio for time-to-first moderate/severe exacerbation was 0.84 (95% CI: 0.63, 1.11; p = .218) for FF/UMEC/VI versus FF/VI and 0.89 (95% CI: 0.62, 1.27; p = .516) versus UMEC/VI. Significant improvements in mean change from baseline in trough FEV1 were observed for FF/UMEC/VI versus FF/VI (treatment difference 137 mL; 95% CI: 86, 188; p < .001) and UMEC/VI (63 mL; 0, 125; p = .050). Health status was improved with FF/UMEC/VI versus both dual therapies. Results were similar to the overall ITT population. No new safety signals were identified. CONCLUSIONS Single-inhaler triple therapy with FF/UMEC/VI versus FF/VI or UMEC/VI reduced the rate and risk of exacerbations, and improved lung function and health status in the China cohort similar to the overall ITT population. No new safety signals were identified.

Abstract
Introduction Inhaled corticosteroids (ICSs) are recommended for patients with frequent exacerbation of chronic obstructive pulmonary disease (COPD). However, accumulating evidence has indicated the risk of pneumonia from the use of ICS. This study aimed to investigate the association between ICS and pneumonia in the real-world clinical setting. Methods A retrospective cohort study was performed using nationwide population data from the Korea National Health Insurance Service. Subjects who had a new diagnosis of COPD and who received inhaled bronchodilators without a diagnosis of pneumonia before the initiation of bronchodilators were identified. Subjects were followed up until their first diagnosis of pneumonia. The risk of pneumonia in ICS users was compared to that in non-ICS users. Results A total of 87,594 subjects were identified and 1:1 matched to 22,161 ICS users and non-ICS users. More ICS users were diagnosed with pneumonia compared to non-ICS users (33.73% versus 24.51%, P<0.0001). The incidence rate per 100,000 person-years was 8904.98 for ICS users and 6206.79 for non-ICS users. The hazard ratio (HR) of pneumonia for ICS users was 1.62 (95% CI 1.54–1.70). The HR of subjects prescribed with the lowest ICS cumulative dose was 1.35 (1.27–1.43). The HR increased to 1.51 (1.42–1.60), 1.96 (1.85–2.09), and 2.03 (1.89–2.18) as the cumulative dose increased. Pneumonia was strongly associated with fluticasone propionate (1.79 (1.70–1.89)) and fluticasone furoate (1.80 (1.61–2.01)) use, compared to the use of other types of ICS. Conclusion ICS increases the risk of pneumonia in patients with COPD. Hence, ICS should be carefully prescribed in patients with risk factors for pneumonia while considering the cumulative doses and subtypes of ICS.

Abstract
Introduction: The current recommendations of chronic obstructive pulmonary disease (COPD) suggest to escalate from inhaled corticosteroid/long-acting β2-adrenoceptor agonist (ICS/LABA) treatment to triple therapy in patients experiencing persistent breathlessness, exercise limitation, or exacerbation. The addition of an ICS to LABA/long-acting muscarinic antagonist (LAMA) combination is recommended for frequently exacerbating patients with high levels of blood eosinophils. Nowadays, three triple therapies have been approved as fixed-dose combinations (FDCs) for the treatment of COPD: beclomethasone dipropionate/formoterol fumarate/glycopyrronium bromide (BDP/FOR/GLY), fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI), and budesonide/glycopyrronium bromide/formoterol fumarate (BUD/GLY/FOR).Areas covered: This narrative review evaluates the efficacy and safety profile of triple FDC therapy for the treatment of COPD, by evaluating the data originating from pivotal randomized-controlled trials (RCTs).Expert opinion: The currently approved triple FDCs exert a protective effect against the risk of COPD exacerbation compared to ICS/LABA and LABA/LAMA, with some concerns regarding the risk of pneumonia for some specific FDCs. Since the assessed RCTs were characterized by important confounders, the obtained results should be interpreted with caution. Indeed, FDCs provide advantages in terms of improved adherence to treatment and lower errors in COPD management; however, direct head-to-head comparisons are needed to establish real differences between the currently approved triple FDCs.

Abstract
Pharmacological medications used for the treatment of COPD patients have increased significantly. Long-acting bronchodilators have been recognized as the mainstay of the treatment of stable COPD, while ICS are usually added in patients with COPD who experience exacerbations, despite bronchodilator treatment. In the latest years, several studies have been published showing the beneficial effect of adding ICS on dual bronchodilation in patients suffering from more severe disease comparing triple therapy with several therapeutic regiments including dual bronchodilation and providing a message that this triple therapy might be more appropriate for COPD patients. However, not all COPD patients have a desirable response to ICS treatment while long-term ICS use in COPD is associated with several side effects. In this report, we aimed to provide a review of the current knowledge on the importance of dual bronchodilation on COPD patients and to compare its use with triple therapy, by covering a wide spectrum of topics. Finally, we propose an algorithm on performing treatment step up from dual bronchodilation to triple therapy and step down from triple to double bronchodilation considering the current evidence.

Abstract
Inhaled corticosteroids (ICSs), when used in combination with long-acting bronchodilators, reduce the risk of exacerbations and improve health-related quality of life in patients with chronic obstructive pulmonary disease (COPD) compared with bronchodilator or ICS therapy alone. Potential side effects of ICSs include adverse effects on glycemic control, bone density, cataract formation, skin changes, oral candidiasis, and pulmonary infections. Pneumonia is observed at increased rates in COPD patients, in particular those with greater airflow limitation, low body mass index, advanced age, and male gender, and ICSs may increase this risk. Risk assessment is essential in selecting appropriate patients for ICS-containing therapy.

Abstract
INTRODUCTION In 2011, the GOLD recommendations for the treatment of Chronic Obstructive Pulmonary Disease (COPD) introduced new clinical elements to classify the severity of the disease and to guide pharmacological choice. For the first time in the GOLD documents, treatment decision was no longer guided only by pulmonary function, but by a more complex combination of pulmonary function and clinical aspects. The recent versions of the GOLD recommendations introduce new aspects for the clinicians and pose new question for the management of the disease. In addition, inflammatory biomarkers and blood eosinophil levels, have been considered to guide treatment selection. AREA COVERED The evolution of disease management proposed by the GOLD document opens several areas of debate. A series of roundtable discussions among respiratory physicians took place in Italy to address key clinical questions. Particularly, the role of lung function and the use of biomarkers, the adherence to international guidelines and the possibility to personalize the pharmacological approach in COPD patients have been discussed, summarized and analyzed. EXPERT OPINION The authors believe that the development of a precision medicine approach tailoring the specific treatment for each patient is the goal of COPD management and may be achieved by considering the phenotypic classification of COPD patients.

Abstract
This study sought to examine whether supplementation of Black Seed Oil (BSO) can improve pulmonary function tests (PFTs), inflammation, and oxidant-antioxidant markers in COPD patients. The study involved 100 patients of mild to moderate COPD divided randomly into 2 groups who were appointed to receive standard medication only (control group) or with additional Black Seed Oil (BSO group). They were assessed initially and after 3 months, 44 patients responded in control group and 47 patients in BSO group. BSO group evidenced a significant decreasing in oxidant and inflammatory markers; thiobarbituric acid reactive-substances (TBARS), protein carbonyl (PC) content, interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α), a significant increase in antioxidants; superoxide dismutase (SOD), catalase (CAT), reduced glutathione (GSH), glutathione peroxidase (GPx), vitamin C, and E, and a significant improvement in PFTs versus control group and baseline levels. Supplementation of Black Seed Oil may be an effective adjunct therapy to improve pulmonary functions, inflammation, and oxidant-antioxidant imbalance in COPD patients.

Abstract
ICS are anti-inflammatory agents which have been suggested to benefit people with worsening symptoms of COPD, by improving lung function, reducing exacerbation of disease, and enhancing overall quality of life. This systematic review and meta-analysis explored the association of the risk of pneumonia in COPD patients that were undergoing treatment using ICS alone or together with LABAs or LAMAs. PubMed, Cochrane Library and EMBASE were systematically searched through August 1, 2019; only double-blinded randomized controlled trials were eligible for this study. Eighteen randomized controlled trials were included. ICS treatment was linked to increased pneumonia incidence (RR, 1.47; 95% CI, 1.26-1.71; p < 0.001; I2 = 39.6%). Patients treated with salmeterol/fluticasone were more likely to have experience pneumonia-related adverse events than those treated using budesonide/formoterol or beclomethasone/formoterol. In subgroup analyses, pneumonia risk was found to be higher in the subgroups: >65 years old, lowest baseline forced expiratory volume in the first second of expiration (FEV1) < 50% of the predicted value, highest ICS dose, and long duration of ICS use. Furthermore, we compared fluticasone propionate with fluticasone furoate and determined that pneumonia incidence was higher in the former group and pneumonia incidence rose as doses rose in these two groups. However, no difference was observed between the budesonide and beclomethasone groups. ICS treatment was linked to an elevated pneumonia risk, different kinds of ICS lead to different rates of pneumonia.

Abstract
To examine clinical outcomes of theophylline use in patients with chronic obstructive pulmonary disease (COPD) receiving inhaled corticosteroids (ICS) and long-acting beta-2 agonists (LABA). Electronic data from five hospitals located in Northern Thailand between January 2011 and December 2015 were retrospectively collected. Propensity score (PS) matching (2:1 ratio) technique was used to minimize confounding factors. The primary outcome was overall exacerbations. Secondary outcomes were exacerbation not leading to hospital admission, hospitalization for exacerbation, hospitalization for pneumonia, and all-cause hospitalizations. Cox's proportional hazards models were used to estimate adjusted hazard ratio (aHR) and 95% confidence interval (CI). After PS matching, of 711 patients with COPD (mean age: 70.1 years; 74.4% male; 60.8% severe airflow obstruction), 474 theophylline users and 237 non-theophylline users were included. Mean follow-up time was 2.26 years. Theophylline significantly increased the risk of overall exacerbation (aHR: 1.48, 95% CI: 1.11-1.96; p = 0.008) and exacerbation not leading to hospital admission (aHR: 1.47, 95% CI: 1.06-2.03; p = 0.020). Theophylline use did not significantly increase the risk of hospitalization for exacerbation (aHR: 1.11, 95% CI: 0.79-1.58; p = 0.548), hospitalization for pneumonia (aHR: 1.28, 95% CI: 0.89-1.84; p = 0.185), and all-cause hospitalizations (aHR: 1.03, 95% CI: 0.80-1.33; p = 0.795). Theophylline use as add-on therapy to ICS and LABA might be associated with an increased risk for overall exacerbation in patients with COPD. A large-scale prospective study of theophylline use investigating both safety and efficacy is warranted.

[PMID: 32471423 PMCID: PMC7257245 DOI: 10.1186/s12931-020-01360-w] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2019] [Accepted: 04/12/2020] [Indexed: 02/06/2023] Open
Abstract
Background The comparative efficacy of inhaled corticosteroid/long-acting muscarinic antagonist/long-acting β2-agonist (ICS/LAMA/LABA) triple therapy administered via single or multiple inhalers in patients with chronic obstructive pulmonary disease (COPD) has not been evaluated comprehensively. We conducted two replicate trials comparing single- with multiple-inhaler ICS/LAMA/LABA combination in COPD. Methods 207608 and 207609 were Phase IV, 12-week, randomized, double-blind, triple-dummy non-inferiority trials comparing once-daily fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) 100/62.5/25 μg via Ellipta inhaler, with twice-daily budesonide/formoterol (BUD/FOR) 400/12 μg via metered-dose inhaler plus once-daily tiotropium (TIO) 18 μg via HandiHaler. Patients had symptomatic COPD and forced expiratory volume in 1 s (FEV1) < 50% predicted, or FEV1 < 80% predicted and ≥ 2 moderate or 1 severe exacerbations in the prior year. The primary endpoint in both trials was weighted mean change from baseline (wmCFB) in 0–24-h FEV1 at Week 12. Secondary endpoints included CFB in trough FEV1 at Day 84 and 85. Other endpoints included serial FEV1 and health status outcomes at Week 12. Safety was evaluated descriptively. Results The modified per-protocol population included 720 and 711 patients in studies 207608 and 207609 (intent-to-treat population: 728 and 732). FF/UMEC/VI was non-inferior to BUD/FOR+TIO for wmCFB in 0–24-h FEV1 at Week 12 (Study 207608 treatment difference [95% confidence interval]: 15 mL [− 13, 43]; Study 207609: 11 mL [− 20, 41]). FF/UMEC/VI improved trough FEV1 CFB versus BUD/FOR+TIO at Day 84 and 85 (Day 85 treatment difference: Study 207608: 38 mL [10, 66]; Study 207609: 51 mL [21, 82]) and FEV1 at 12 and 24 h post-morning dose at Week 12 in both studies. No treatment differences were seen in health status outcomes. Safety profiles were similar between treatments; pneumonia occurred in 7 (< 1%) patients with FF/UMEC/VI and 9 (1%) patients with BUD/FOR+TIO, across both studies. Conclusions FF/UMEC/VI was non-inferior to BUD/FOR+TIO for wmCFB in 0–24-h FEV1 at Week 12 in patients with COPD. Greater improvements in trough and serial FEV1 measurements at Week 12 with FF/UMEC/VI versus BUD/FOR+TIO, together with similar health status improvements and safety outcomes including the incidence of pneumonia, suggest that once-daily single-inhaler FF/UMEC/VI triple therapy is a viable option for patients looking to simplify their treatment regimen. Trial registration GSK (207608/207609; NCT03478683/NCT03478696).

Abstract
Chronic obstructive pulmonary disease (COPD) is characterized by airflow limitation with persistent respiratory symptoms. Current therapeutics for COPD are largely borrowed from the drug armamentarium for the treatment of asthma, which has different pathophysiological mechanisms from COPD. COPD has been linked to dysregulated expression of mRNAs and noncoding (nc)RNAs including miRNAs, PIWI-interacting (pi)RNAs, long noncoding (lnc)RNAs, and circular (circ)RNAs. This review highlights and discusses some recent advances towards development of RNA therapeutics for COPD.

Association of Guideline-Recommended COPD Inhaler Regimens With Mortality, Respiratory Exacerbations, and Quality of Life: A Secondary Analysis of the Long-Term Oxygen Treatment Trial. Chest 2020; 158:529-538.

Abstract
BACKGROUND Although inhaled therapy reduces exacerbations among patients with COPD, the effectiveness of providing inhaled treatment per risk stratification models remains unclear. RESEARCH QUESTION Are inhaled regimens that align with the 2017 Global Initiative for Chronic Obstructive Lung Disease (GOLD) strategy associated with clinically important outcomes? STUDY DESIGN AND METHODS We conducted secondary analyses of Long-term Oxygen Treatment Trial (LOTT) data. The trial enrolled patients with COPD with moderate resting or exertional hypoxemia between 2009 and 2015. Our exposure was the patient-reported inhaled regimen at enrollment, categorized as either aligning with, undertreating, or potentially overtreating per the 2017 GOLD strategy. Our primary composite outcome was time to death or first hospitalization for COPD. Additional outcomes included individual components of the composite outcome and time to first exacerbation. We generated multivariable Cox proportional hazard models across strata of GOLD-predicted exacerbation risk (high vs low) to estimate between-group hazard ratios for time to event outcomes. We adjusted models a priori for potential confounders, clustered by site. RESULTS The trial enrolled 738 patients (73.4% men; mean age, 68.8 years). Of the patients, 571 (77.4%) were low risk for future exacerbations. Of the patients, 233 (31.6%) reported regimens aligning with GOLD recommendations; most regimens (54.1%) potentially overtreated. During a 2.3-year median follow-up, 332 patients (44.9%) experienced the composite outcome. We found no difference in time to composite outcome or death among patients reporting regimens aligning with recommendations compared with undertreated patients. Among patients at low risk, potential overtreatment was associated with higher exacerbation risk (hazard ratio, 1.42; 95% CI, 1.09-1.87), whereas inhaled corticosteroid treatment was associated with 64% higher risk of pneumonia (incidence rate ratio, 1.64; 95% CI, 1.01-2.66). INTERPRETATION Among patients with COPD with moderate hypoxemia, we found no difference in clinical outcomes between inhaled regimens aligning with the 2017 GOLD strategy compared with those that were undertreated. These findings suggest the need to reevaluate the effectiveness of risk stratification model-based inhaled treatment strategies.

Abstract
OBJECTIVES To evaluate the degree to which evidence from large clinical trials can be applied to patients treated in a local hospital cohort of COPD outpatients. METHODS The authors selected seventeen RCTs identified in a systematic way from GOLD 2019 consensus document, and applied their inclusion and exclusion criteria to a real-world cohort of a previous cross-sectional study of 303 COPD outpatients included consecutively. RESULTS When the inclusion criteria of the 17 RCTs were applied to a real-world cohort of COPD outpatients, only a small portion of them were eligible to participate in the referred trials, from 4.29% to 60.07%. However, when both the inclusion and the exclusion criteria were applied, only as little as 3.63% to as much as 40.59% of patients were eligible to participate. Hence, only a small fraction of patients from this cohort could benefit from the findings of these RCTs. CONCLUSIONS There is a need to complement the efficacy evidence provided by large RCTs according to the extent to which their results, designed to target significant patient populations, can be applied to typical patients treated in routine clinical practice.

Abstract
BACKGROUND Patients with chronic obstructive pulmonary disease (COPD) are at risk of exacerbations and pneumonia; how the risk factors interact is unclear. METHODS This post-hoc, pooled analysis included studies of COPD patients treated with inhaled corticosteroid (ICS)/long-acting β2 agonist (LABA) combinations and comparator arms of ICS, LABA, and/or placebo. Backward elimination via Cox's proportional hazards regression modelling evaluated which combination of risk factors best predicts time to first (a) pneumonia, and (b) moderate/severe COPD exacerbation. RESULTS Five studies contributed: NCT01009463, NCT01017952, NCT00144911, NCT00115492, and NCT00268216. Low body mass index (BMI), exacerbation history, worsening lung function (Global Initiative for Chronic Obstructive Lung Disease [GOLD] stage), and ICS treatment were identified as factors increasing pneumonia risk. BMI was the only pneumonia risk factor influenced by ICS treatment, with ICS further increasing risk for those with BMI <25 kg/m2. The modelled probability of pneumonia varied between 3 and 12% during the first year. Higher exacerbation risk was associated with a history of exacerbations, poorer lung function (GOLD stage), female sex and absence of ICS treatment. The influence of the other exacerbation risk factors was not modified by ICS treatment. Modelled probabilities of an exacerbation varied between 31 and 82% during the first year. CONCLUSIONS The probability of an exacerbation was considerably higher than for pneumonia. ICS reduced exacerbations but did not influence the effect of risks associated with prior exacerbation history, GOLD stage, or female sex. The only identified risk factor for ICS-induced pneumonia was BMI <25 kg/m2. Analyses of this type may help the development of COPD risk equations.

Abstract
Background Asthma-COPD overlap (ACO) is a disease that shares clinical features of both asthma and COPD. The purpose of this study is to investigate the prevalence and clinical features of ACO. Methods We retrospectively reviewed data for 170 patients with persistent airflow limitation and diagnosed them according to "The Japanese Respiratory Society Guidelines for the Management of ACO 2018". Results Of the 170 patients, 111 were diagnosed as follows : COPD (74 patients, 66.6%), ACO (34 patients, 30.6%), and asthma (3 patients, 2.8%). There was no significant difference in clinical features between ACO and COPD patients. The following pulmonary function tests were significantly lower in ACO than in COPD patients : forced expiratory volume in 1 second/forced vital capacity, peak expiratory flow, maximal mid-expiratory flow, and the maximum expiratory flow at 50%and75%. The following respiratory impedance parameters were significantly higher in ACO than in COPD patients : respiratory resistance (Rrs) at 5 Hz (R5), Rrsat 20 Hz (R20), R5-R20, and low-frequency reactance area. Conclusions About 30% of patients with persistent airflow limitation were diagnosed with ACO. ACO patients had lower lung function and higher respiratory impedance compared with COPD patients. J.

Abstract
Introduction Antibiotics are routinely given to people with chronic obstructive pulmonary disease (COPD) presenting with lower respiratory tract infection (LRTI) symptoms in primary care. Population prescribing habits and their consequences have not been well-described. Methods We conducted a retrospective analysis of antibiotic prescriptions for non-pneumonic exacerbations of COPD from 2010 to 2015 using the UK primary care Optimum Patient Care Research Database. As a proxy of initial treatment failure, second antibiotic prescriptions for LRTI or all indications within 14 days were the primary and secondary outcomes, respectively. We derived a model for repeat courses using univariable and multivariable logistic regression analysis. Results A total of 8.4% of the 9042 incident events received further antibiotics for LRTI, 15.5% further courses for any indication. Amoxicillin and doxycycline were the most common index and second-line drugs, respectively (58.7% and 28.7%), mostly given for 7 days. Index drugs other than amoxicillin, cardiovascular disease, pneumococcal vaccination and more primary care consultations were statistically significantly associated with repeat prescriptions for LRTI (p<0.05). The ORs and 95% CIs were: OR 1.28, 95% CI 1.10 to 1.49; OR 1.37, 95% CI 1.13 to 1.66; OR 1.33, 95% CI 1.14 to 1.55 and OR 1.05, 95% CI 1.02 to 1.07, respectively. Index duration, inhaled steroid use and exacerbation frequency were not statistically significant. The derived model had an area under the curve of 0.61, 95% CI 0.59 to 0.63. Discussion The prescription of multiple antibiotic courses for COPD exacerbations was relatively common-one in twelve patients receiving antibiotics for LRTI had a further course within 2 weeks. The findings support the current preference for amoxicillin as index drug within the limitations of this observational study. Further clinical trials to determine best practice in this common clinical situation appear required.

Abstract
BACKGROUND Single inhaler triple therapies providing an inhaled corticosteroid, a long-acting muscarinic antagonist, and a long-acting β2-agonist (ICS/LAMA/LABAs) are an emerging treatment option for chronic obstructive pulmonary disease (COPD). Nevertheless, questions remain regarding the optimal patient population for triple therapy as well as the benefit:risk ratio of ICS treatment. METHODS ETHOS is an ongoing, randomized, double-blind, multicenter, parallel-group, 52-week study in symptomatic patients with moderate-to-very severe COPD and a history of exacerbation(s) in the previous year. Two doses of single inhaler triple therapy with budesonide/glycopyrrolate/formoterol fumarate metered dose inhaler (BGF MDI 320/18/9.6 μg and 160/18/9.6 μg) will be compared to glycopyrrolate/formoterol fumarate (GFF) MDI 18/9.6 μg and budesonide/formoterol fumarate (BFF) MDI 320/9.6 μg, all formulated using co-suspension delivery technology. Outcomes include the rate of moderate/severe (primary endpoint) and severe COPD exacerbations, symptoms, quality of life, and all-cause mortality. Sub-studies will assess lung function and cardiovascular safety. STUDY POPULATION From June 2015-July 2018, 16,044 patients were screened and 8572 were randomized. Preliminary baseline demographics show that 55.9% of patients had experienced ≥2 moderate/severe exacerbations in the previous year, 79.1% were receiving an ICS-containing treatment at study entry, and 59.9% had blood eosinophil counts ≥150 cells/mm3. CONCLUSIONS ETHOS will provide data on exacerbations, patient-reported outcomes, mortality, and safety in 8572 patients with moderate-to-very severe COPD receiving triple and dual fixed-dose combinations. For the first time, ICS/LAMA/LABA triple therapy with two different doses of ICS will be compared to dual ICS/LABA and LAMA/LABA therapies. CLINICAL TRIAL REGISTRATION NUMBER NCT02465567.

Abstract
Chronic obstructive pulmonary disease (COPD) is a major disease in Asia. However, how to manage specifically Asian COPD patients has not been proposed. Awareness of COPD is very low and underdiagnosis/undertreatment is common in Asian countries. Low utilization of pulmonary function test and inhalers is also a problem. Moreover, high smoking prevalence and air pollution are barriers to managing Asian patients with COPD. The relatively low body mass index of Asian patients with COPD can increase their risk for experiencing adverse effects from COPD drugs. Physicians should consider the unique features of Asian populations with COPD such as the high prevalence rates of bronchiectasis and tuberculosis-destroyed lungs, biomass smoke exposure and parasitic infection.

Abstract
Observational studies indicate that overutilization of inhaled corticosteroids (ICS) is common in patients with chronic obstructive pulmonary disease (COPD). Overprescription and the high risk of serious ICS-related adverse events make withdrawal of this treatment necessary in patients for whom the treatment-related risks outweigh the expected benefits. Elaboration of an optimal, universal, user-friendly algorithm for withdrawal of ICS therapy has been identified as an important clinical need. This article reviews the available evidence on the efficacy, risks, and indications of ICS in COPD, as well as the benefits of ICS treatment withdrawal in patients for whom its use is not recommended by current guidelines. After discussing proposed approaches to ICS withdrawal published by professional associations and individual authors, we present a new algorithm developed by consensus of an international group of experts in the field of COPD. This relatively simple algorithm is based on consideration and integrated assessment of the most relevant factors (markers) influencing decision-making, such a history of exacerbations, peripheral blood eosinophil count, presence of infection, and risk of community-acquired pneumonia.
