Abstract
Chronic obstructive pulmonary disease patient care must include confirming a diagnosis with postbronchodilator spirometry. Because of the clinical heterogeneity and the reality that airflow obstruction assessed by spirometry only partially reflects disease severity, a thorough clinical evaluation of the patient should include assessment of symptom burden and risk of exacerbations that permits the implementation of evidence-informed pharmacologic and nonpharmacologic interventions. This guideline provides recommendations from a comprehensive systematic review with a meta-analysis and expert-informed clinical remarks to optimize maintenance pharmacologic therapy for individuals with stable COPD, and a revised and practical treatment pathway based on new evidence since the 2019 update of the Canadian Thoracic Society (CTS) Guideline. The key clinical questions were developed using the Patients/Population (P), Intervention(s) (I), Comparison/Comparator (C), and Outcome (O) model for three questions that focuses on the outcomes of symptoms (dyspnea)/health status, acute exacerbations, and mortality. The evidence from this systematic review and meta-analysis leads to the recommendation that all symptomatic patients with spirometry-confirmed COPD should receive long-acting bronchodilator maintenance therapy. Those with moderate to severe dyspnea (modified Medical Research Council ≥ 2) and/or impaired health status (COPD Assessment Test ≥ 10) and a low risk of exacerbations should receive combination therapy with a long-acting muscarinic antagonist/long-acting ẞ2-agonist (LAMA/LABA). For those with a moderate/severe dyspnea and/or impaired health status and a high risk of exacerbations should be prescribed triple combination therapy (LAMA/LABA/inhaled corticosteroids) azithromycin, roflumilast or N-acetylcysteine is recommended for specific populations; a recommendation against the use of theophylline, maintenance systemic oral corticosteroids such as prednisone and inhaled corticosteroid monotherapy is made for all COPD patients.

Abstract
BACKGROUND Inhaled corticosteroids (ICSs) are associated with an increased risk of pneumonia among patients with chronic obstructive pulmonary disease (COPD). The introduction of extrafine particle ICS has aimed to improve the distribution of medicine in the airways by altering deposition within the lungs, potentially affecting efficacy and side effects. It remains unclear if extrafine particle ICS administration alters the risk of pneumonia compared with standard particle size ICS. METHODS An observational cohort study including all Danish COPD outpatients receiving ICS from 2010 to 2017. The primary outcome was pneumonia hospitalisation in the different ICS particle dosing regimens. The primary analysis was an adjusted Cox proportional hazards model. For sensitivity analysis, a subgroup analysis of patients receiving spray devices was done. Further, we created a propensity score matched cohort, in which we matched for the same covariates as adjusted for in the main analysis. RESULTS A total of 35 691 patients were included of whom 1471 received extrafine particle ICS. Among these patients, 4657 were hospitalised due to pneumonia. Patients with COPD receiving extrafine particle ICS had a lower risk of hospitalisation due to pneumonia compared with patients receiving standard particle size ICS in our primary analysis (HR 0.75; 95% CI 0.63 to 0.89; p=0.002), subgroup analysis (HR 0.54; 95% CI 0.45 to 0.65; p<0.0001) and the propensity-matched population (HR 0.72; 95% CI 0.60 to 0.87; p=0.0006). INTERPRETATION The use of extrafine particle ICS administration was associated with a lower risk of pneumonia hospitalisation in patients with COPD compared with those who received standard size treatment.

Abstract
BACKGROUND Maintenance and reliever therapy (MART) with inhaled corticosteroid (ICS)/formoterol effectively reduces exacerbations in asthma. We aimed to investigate its efficacy compared with fixed-dose fluticasone/salmeterol in chronic obstructive pulmonary disease (COPD). METHODS Patients with COPD and ≥1 exacerbation in the previous 2 years were randomly assigned to open-label MART (Spiromax budesonide/formoterol 160/4.5 µg 2 inhalations twice daily+1 prn) or fixed-dose therapy (Diskus fluticasone propionate/salmeterol combination (FSC) 500/50 µg 1 inhalation twice daily+salbutamol 100 µg prn) for 1 year. The primary outcome was rate of moderate/severe exacerbations, defined by treatment with oral prednisolone and/or antibiotics. RESULTS In total, 195 patients were randomised (MART Bud/Form n=103; fixed-dose FSC n=92). No significant difference was seen between MART and FSC therapy in exacerbation rates (1.32 vs 1.32 /year, respectively, rate ratio 1.05 (95% CI 0.79 to 1.39); p=0.741). No differences in lung function parameters or health status were observed. Total ICS dose was significantly lower with MART than FSC therapy (budesonide-equivalent 928 µg/day vs 1747 µg/day, respectively, p<0.05). Similar proportions of patients reported adverse events (MART Bud/Form: 73% vs fixed-dose FSC: 68%, p=0.408) and pneumonias (MART: 5% vs FSC: 1%, p=0.216). CONCLUSIONS This first study of MART in COPD found that budesonide/formoterol MART might be similarly effective to fluticasone/salmeterol fixed-dose therapy in moderate to severe patients with COPD, at a lower daily ICS dosage. Further evidence is needed about long-term safety.

Different inhaled corticosteroid doses in triple therapy for chronic obstructive pulmonary disease: systematic review and Bayesian network meta-analysis. Sci Rep 2022; 12:15698. [PMID: 36127353 PMCID: PMC9489688 DOI: 10.1038/s41598-022-18353-y] [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: 03/29/2022] [Accepted: 08/10/2022] [Indexed: 11/25/2022] Open
Abstract
A systematic review and Bayesian network meta-analysis is necessary to evaluate the efficacy and safety of triple therapy with different doses of inhaled corticosteroids (ICS) in stable chronic obstructive pulmonary disease (COPD). We selected 26 parallel randomized controlled trials (41,366 patients) comparing triple therapy with ICS/long-acting beta-agonist (LABA), LABA/long-acting muscarinic antagonist (LAMA), and LAMA in patients with stable COPD for ≥ 12 weeks from PubMed, EMBASE, the Cochrane Library, and clinical trial registries (search from inception to June 30, 2022). Triple therapy with high dose (HD)-ICS exhibited a lower risk of total exacerbation in pre-specified subgroups treated for ≥ 48 weeks than that with low dose (LD)-ICS (odds ratio [OR] = 0.66, 95% credible interval [CrI] = 0.52–0.94, low certainty of evidence) or medium dose (MD)-ICS (OR = 0.66, 95% CrI = 0.51–0.94, low certainty of evidence). Triple therapy with HD-ICS exhibited a lower risk of moderate-to-severe exacerbation in pre-specified subgroups with forced expiratory volume in 1 s < 65% (OR = 0.6, 95% CrI = 0.37–0.98, low certainty of evidence) or previous exacerbation history (OR = 0.6, 95% CrI = 0.36–0.999, very low certainty of evidence) than triple therapy with MD-ICS. Triple therapy with HD-ICS may reduce acute exacerbation in patients with COPD treated with other drug classes including triple therapy with LD- or MD-ICS or dual therapies.

Abstract
Purpose To determine the clinical and economic impact of inhaled corticosteroid (ICS) withdrawal in Spanish patients with COPD receiving triple therapy (TT) with ICS, long-acting β2-agonist (LABA), and long-acting muscarinic antagonist (LAMA). Patients and Methods This was an observational, retrospective study of BIG-PAC database medical records. Patients aged ≥40 years receiving TT from 2016 to 2018 were followed for 1 year. Two cohorts were identified: patients continuing TT (ICS+LABA+LAMA), and patients receiving TT with ICS withdrawn (LABA+LAMA). Variables included medication, exacerbations (moderate and severe), pneumonia, mortality, health resource use (HRU), and cost per patient/year. Cohorts were compared using propensity score matching (PSM). Multivariate statistical analysis using analysis of covariance and Cox proportional risks was conducted. Results Of 6541 patients included, 5740 (87.8%) continued TT and 801 (12.2%) had ICS withdrawn. Patients with ICS withdrawal were younger, had lower disease burden, higher ICS doses, and more exacerbations compared with those continuing ICS. PSM matched 795 patients in each cohort. Mean age was 68.5 years (SD: 11.2), 69.9% were male, and mean Charlson index was 2.0. Patients with ICS withdrawal had more total exacerbations in the 12 months following withdrawal compared with patients continuing TT (36.6% vs 31.4%; p=0.030). No significant differences were found for pneumonia (3.3% vs 3.6%; p=0.583) and mortality (9.9% vs 7.5%; p=0.092). Median time to first exacerbation was shorter in patients with ICS withdrawal compared with those continuing ICS (HR: 0.69, 95% CI: 0.57–0.83; p<0.001). Mean health cost per patient/year among patients with ICS withdrawal was higher than those continuing TT (€2993 vs €2130; p<0.001). Conclusion ICS withdrawal in patients with COPD receiving TT was associated with increased exacerbations, HRU, and costs compared with continuing TT, with health and economic impacts on patients and the Spanish National Healthcare System, respectively. Pneumonia and mortality rates were similar between groups.

Costs and Clinical Consequences of Compliance with COPD GOLD Recommendations or National Guidelines Compared with Current Clinical Practice in Belgium, Germany, Sweden, and the United States.

Abstract
Purpose The objective of this study was to assess the clinical and cost benefits of treating patients with chronic obstructive pulmonary disease (COPD) according to global and national guidelines compared to real-life clinical practice in the United States and three European countries (Belgium, Germany, Sweden). Patients and Methods A cost-consequence model was developed to compare current prescribing patterns with two alternative scenarios, the first aligned with the Global Initiative for Chronic Obstructive Lung Disease (GOLD 2022) recommendations and the second with national guidelines. Costs and clinical outcomes were modeled for these alternative scenarios over a time horizon of one year, based on real-world evidence and health insurance data. Results Current clinical practice in each of the countries was inconsistent with published recommendations. A redistribution to prescribing patterns according to global and national recommendations led to a substantial decrease in the use of inhaled corticosteroid (ICS) containing therapies of more than 80% and 44%, respectively. There was a reduced incidence of up to 16% of mild-to-moderate pneumonia and up to 29% of severe pneumonia. Exacerbations decreased across all countries apart from Sweden, where a small increase in the rate of exacerbations was due to the redistribution of some patients currently undergoing inhaled triple therapy to non-ICS-containing therapies. Adapting treatment to recommendations could provide potential cost savings of up to 13% in estimated annual direct costs, resulting predominantly from the reduction in cost of healthcare resource use, including hospitalization associated with treating incident pneumonia, particularly severe pneumonia. Cost savings for prevalent adult patients with COPD on long-acting inhaler therapy ranged from €31 to €675 per patient per year. Conclusion Redistribution of COPD patients from current clinical practice to treatment according to published recommendations would provide clinical benefits and substantial cost savings.

J Clin Med 2022; 11:jcm11154491. [PMID: 35956108 PMCID: PMC9369741 DOI: 10.3390/jcm11154491] [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: 06/23/2022] [Revised: 07/26/2022] [Accepted: 07/29/2022] [Indexed: 12/04/2022] Open
Abstract
Background: Triple fixed-dose combination (FDC) therapy is recommended in severe chronic obstructive pulmonary disease (COPD) patients experiencing frequent exacerbations and/or symptoms not controlled by dual FDCs. Since no randomized controlled trials (RCTs) have directly compared the different inhaled corticosteroid/long-acting β2-adrenoceptor agonist/long-acting muscarinic antagonist (ICS/LABA/LAMA) FDCs, we performed a meta-analysis to compare the impact of the current available ICS/LABA/LAMA FDCs in COPD. Methods: A meta-analysis was performed by connecting beclomethasone dipropionate/formoterol fumarate/glycopyrronium bromide or glycopyrrolate (BDP/FOR/GLY), budesonide (BUD)/GLY/FOR, and fluticasone furoate/umeclidinium bromide/vilanterol (FF/UMEC/VI) FDCs via ICS/LABA or LABA/LAMA FDCs arms. The safety and efficacy profiles were investigated, and the Implemented Bidimensional Surface under the cumulative ranking curve analysis (IBiS) was carried out. Protocol registration: CRD42022301189. Results: Data from 21,809 COPD patients were extracted from the ETHOS, IMPACT, KRONOS, and TRILOGY studies. No significant (p > 0.05) differences were detected across the triple FDCs with respect to the risk of exacerbation, trough forced expiratory volume in the first second (FEV1), transition dyspnea index (TDI), St. George’s Respiratory Questionnaire (SGRQ), risk of serious adverse events (SAEs), cardiovascular (CV) SAEs, pneumonia, and all-cause mortality. According to IBiS score, BDP/FOR/GLY 200/12/25 µg twice daily (BID) was the FDC reporting the best combined efficacy/safety profile (area 41.41%), although FF/UMEC/VI 100/62.5/25 µg once daily (QD) showed the greatest efficacy profile (50.54%). The protection against mortality related to the dose of ICS. Conclusions: All triple FDCs are effective and safe in COPD regardless of the regimen of administration (twice daily vs. once daily), with no relevant difference in the risk of CV SAEs and pneumonia.

Abstract
Administration of inhaled corticosteroids (ICS) is one of the most controversial issues in the treatment of stable chronic obstructive pulmonary disease (COPD). Associations between these drugs and increased incidence of severe pneumonia and other respiratory infections have already been reported in literature, as well as effects on the immune system and on the lung microbiota. ICS vary in their pharmacodynamic and pharmacokinetic properties, despite being widely considered therapeutically similar. The use of ICS requires, therefore, a deep knowledge of their pharmacokinetics and pharmacodynamics to obtain the maximum benefit and the least side effects. Defining new phenotypes-endotypes of COPD may lead to novel pharmacological and therapeutic scenarios while define the correct indications for prescription of ICS. Titration is certainly an important means by which these objectives can be achieved.

Abstract
Chronic obstructive pulmonary disease (COPD) has a significant impact on healthcare systems and health-related quality of life. Increased prevalence of smoking is an important factor contributing to high burden of COPD in the Middle East and Africa (MEA). Several other factors including sedentary lifestyle, urbanization, second-hand smoke, air pollution, and occupational exposure are also responsible for the upsurge of COPD in the MEA. Frequent COPD exacerbations accelerate disease progression, progressively deteriorate the lung function, and negatively affect quality of life. This consensus is based on review of the published evidence, international and regional guidelines, and insights provided by the expert committee members from the MEA region. Spirometry, though the gold standard for diagnosis, is often unavailable and/or underutilized leading to underdiagnosis of COPD in primary care settings. Low adherence to the treatment guidelines and delayed use of appropriate combination therapy including triple therapy are additional barriers in management of COPD in MEA. It is necessary to recognize COPD as a screenable condition and develop easy and simple screening tools to facilitate early diagnosis. Knowledge of the disease symptomatology at patient and physician level and adherence to the international or regional guidelines are important to create awareness about harmful effects of smoking and develop national guidelines to focus on prevention on COPD. Implementation of vaccination program and pulmonary rehabilitation are equally valuable to manage patients with COPD at local and regional level. We present recommendations made by the expert panel for improved screening, diagnosis, and management of COPD in MEA.

Abstract
Chronic obstructive pulmonary disease (COPD) is one of the leading global causes of morbidity and mortality. A hallmark of COPD is progressive airflow obstruction primarily caused by cigarette smoke (CS). CS exposure causes an imbalance favoring pro- over antioxidants (oxidative stress), leading to transcription factor activation and increased expression of inflammatory mediators and proteases. Different cell types, including macrophages, epithelial cells, neutrophils, and T lymphocytes, contribute to COPD pathophysiology. Alteration in cell functions results in the generation of an oxidative and inflammatory microenvironment, which contributes to disease progression. Current treatments include inhaled corticosteroids and bronchodilator therapy. However, these therapies do not effectively halt disease progression. Due to the complexity of its pathophysiology, and the risk of exacerbating symptoms with existing therapies, other specific and effective treatment options are required. Therapies directly or indirectly targeting the oxidative imbalance may be promising alternatives. This review briefly discusses COPD pathophysiology, and provides an update on the development and clinical testing of novel COPD treatments.

Personalising add-on treatment with inhaled corticosteroids in patients with chronic obstructive pulmonary disease: a benefit-harm modelling study. LANCET DIGITAL HEALTH 2021; 3:e644-e653. [PMID: 34452874 DOI: 10.1016/s2589-7500(21)00130-8] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/04/2020] [Revised: 06/11/2021] [Accepted: 06/16/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND Since the benefit-harm balance of adding inhaled corticosteroids to long-acting β2-agonists (LABA) and long-acting muscarinic antagonists (LAMA) for patients with chronic obstructive pulmonary disease is unclear, we evaluated this addition for a range of patient profiles. METHODS Analyses considered the effects of low-to-moderate doses of inhaled corticosteroids, LABA, and LAMA compared with LABA and LAMA alone, outcome incidences, and preference weights assigned to averted moderate-to-severe exacerbations (benefit) and severe pneumonia, candidiasis, and dysphonia (harm). Using exponential models, we estimated the preference weight-adjusted 2-year net clinical benefit (ie, benefits outweighing harms) indices. Exacerbation risk thresholds for triggering inhaled corticosteroids, LABA, and LAMA were established when the probability of a 2-year net clinical benefit reached 60%. We estimated the proportion of patients benefiting from added inhaled corticosteroids using an externally validated prediction model for acute exacerbations in primary care. FINDINGS Adding low-to-moderate dose inhaled corticosteroids to LABA and LAMA provided a net clinical benefit in patients with a 2-year baseline exacerbation risk of 54-83%. Low-dose inhaled corticosteroids showed a net clinical benefit if the baseline risk was 40-91%, but not at higher doses. The benefit was modified by blood eosinophil count (BEC) and age. Although no net benefit was associated with a BEC of less than 150 cells per μL, patients with a BEC of 150 cells per μL or more had a net benefit from low-dose inhaled corticosteroids with a 2-year exacerbation risk of 32-95% in those aged 40-79 years and 41-93% in those older than 80 years. A moderate dose of inhaled corticosteroids showed a net benefit in patients younger than 80 years with a BEC of 150 cells per μL or more at 52-86% 2-year exacerbation risk. Depending on the subgroups, the proportion of patients with a net benefit from added inhaled corticosteroids ranged from 0 to 68%. INTERPRETATION The net clinical benefit of adding different inhaled corticosteroid doses to LABA and LAMA varies greatly with exacerbation risk, BEC, and age. Personalised treatment decisions based on these factors and predicted exacerbation risks might reduce overtreatment and undertreatment with inhaled corticosteroids. FUNDING None.

Efficacy and safety of single-inhaler triple therapy of glycopyrronium, formoterol and fluticasone in patients with COPD: a double-blind, randomised controlled trial. ERJ Open Res 2021; 7:00255-2021. [PMID: 34322547 PMCID: PMC8311133 DOI: 10.1183/23120541.00255-2021] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Accepted: 05/07/2021] [Indexed: 11/05/2022] Open
Abstract
BACKGROUND The aim of this work was to investigate the safety and efficacy of single-inhaler triple therapy with 12.5 μg glycopyrronium (GB)/12 μg formoterol fumarate (FF)/250 μg fluticasone propionate (FP), compared to 50 μg GB co-administered with a fixed dose of 12 μg FF/250 μg FP in subjects with COPD. METHODS This was a phase 3, randomised, double-blind, active-control, parallel-group, noninferiority study conducted at 20 sites across India. COPD patients aged ≥40 to ≤75 years, with forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) <0.70, using mono/dual therapy with inhaled corticosteroids (ICSs), long-acting muscarinic antagonists (LAMAs), or long-acting β-agonists (LABAs) for ≥1 month, were included. Subjects were randomised 1:1 to GB/FF/FP or GB+FF/FP for 12 weeks. The primary efficacy end-point was the change from baseline in trough FEV1 at the end of 12 weeks. The study is registered with the Clinical Trials Registry of India (identifier number: CTRI/2019/01/017156). RESULTS Between 23 March 2019 and 14 February 2020, 396 subjects were enrolled, with 198 patients each in the fixed-triple (GB/FF/FP) and open-triple (GB+FF/FP) groups. The difference in least-square mean (LSM) changes in pre-dose FEV1 from baseline at 12 weeks was noninferior between the groups (p<0.05). The LSM change from baseline in post-dose FEV1 was comparable (p=0.38). A superiority test showed comparable efficacy (p=0.12) for the difference in mean change from baseline in trough FEV1 between the groups. Adverse events (mild or moderate) were recorded in 25.3% and 24.9% of subjects in the GB/FF/FP and GB+FF/FP groups. CONCLUSIONS Fixed triple therapy with GB/FF/FP provides comparable bronchodilation and lung function improvement as open-triple therapy. It is safe and well tolerated in symptomatic COPD patients with a history of exacerbations.

Impact of health technology assessment on prescribing patterns of inhaled fixed-dose combination triple therapy in chronic obstructive pulmonary disease. JOURNAL OF MARKET ACCESS & HEALTH POLICY 2021; 9:1929757. [PMID: 34122781 PMCID: PMC8174477 DOI: 10.1080/20016689.2021.1929757] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/14/2020] [Revised: 05/03/2021] [Accepted: 05/07/2021] [Indexed: 06/12/2023]
Abstract
Background: Evidence suggests that triple therapy for patients with chronic obstructive pulmonary disease (COPD) is being used in a broader range of patients than recommended by guidelines, which may have health and cost implications. Objective: To explore the relationship between national health technology assessment (HTA) agency appraisals and market penetration of two fixed-dose combination (FDC) triple therapies. Study design: HTAs from Q3 2017 to Q1 2020 from 10 countries were evaluated. Intervention: Glycopyrronium bromide/formoterol fumarate/beclomethasone (Trimbow®) and umeclidinium/vilanterol/fluticasone furoate (Trelegy™ Ellipta®). Main outcome measure: HTA restrictions and prescribing rates (days of therapy). Results: Seven countries (70%) imposed restrictions on use including prescription only for patients stable on free-combination triple therapy or not controlled on dual therapy, requirement of a specialist prescription or therapeutic plan, prescription only for patients with severe COPD, and use as second-line therapy or later. In general, countries that have imposed restrictions on the use of FDC triple therapies have seen a lower than average uptake. Conclusion: Payer guidance on prescribing FDC triple therapy may potentially support more appropriate prescribing in line with clinical guidelines. It is important for payers to consider which restrictions would ensure the most efficient use of scarce resources.

Abstract
Objective To determine the clinical and economic consequences of inhaled corticosteroid doses and particle size in patients on triple-inhalation therapy for COPD. Methods Patients aged ≥40 years who initiated treatment with multi-inhaler triple-inhaled therapy between 1 January 2015 and 31 March were included and followed for 1 year. Patients were grouped according to inhaled corticosteroid (ICS) dose (low/medium/high) and particle size device (extrafine/non-extrafine particles). Outcome variables were moderate and severe exacerbations, pneumonia and healthcare resource use (HCRU) costs. A multivariate analysis was performed for model correction (p<0.05). Results A total of 2185 patients (mean age 72.3 years, 82.9% male) were analysed. Of these, 849 (38.9%) patients received low-dose ICS, 612 medium-dose ICS (28.0%) and 724 (33.1%) high-dose ICS. Exacerbations occurred more frequently with increasing IC dose (low: 26.4%, medium: 28.7% and high: 30.4%; p=0.047), as did the proportion of pneumonia (3.4%, 4.2% and 6.9%, respectively (p=0.041)). The annual mean cost/unit was € 2383 for low dose, € 2401 for medium dose and € 2625 for high dose (p=0.024). Four hundred and sixty-two (31.6%) patients used an extrafine particle device and 999 (68.4%) a non-extrafine particle device: the proportion of exacerbations was 24.0% vs 30.4% (p=0.012), and the annual mean cost/unit was € 2090 vs € 2513, respectively (p<0.001). The number of exacerbations was directly correlated with FEV1 (β= −0.157), age (β=0.071), Charlson index (β=0.050) and device type (extrafine: β=0.049) (p<0.02). Conclusion In patients with COPD receiving multi-inhaler triple therapy, higher ICS doses were not associated with a further reduction in exacerbations, whereas we found an increased risk of pneumonia. The use of inhaler devices delivering extrafine ICS particle was associated with a lower rate of exacerbations, resulting in lower overall HCRU costs.

Abstract
The heterogeneity of chronic obstructive pulmonary disease (COPD) creates many diagnostic, prognostic, treatment and management challenges, as the pathogenesis of COPD is highly complex and the underlying cellular and molecular mechanisms remain poorly understood. A reliable, easy-to-measure, clinically relevant biomarker would be invaluable for improving outcomes for patients. International and national guidance for COPD suggests using blood eosinophil counts as a biomarker to help estimate likely responsiveness to inhaled corticosteroids (ICS) and, potentially, to aid effective management strategies. However, with the mechanism underlying the association between higher eosinophil levels and ICS effect unknown, use of the blood eosinophil count in COPD continues to be widely debated by the respiratory community. Two international meetings involving respiratory medicine specialists, immunologists and primary and secondary care clinicians were held in November 2018 and March 2019, facilitated and funded by GlaxoSmithKline plc. The aims of these meetings were to explore the role of eosinophils in the disease processes of COPD and as prognostic and diagnostic markers, and to identify areas of deficient knowledge that warrant further research. The consensus views of the attendees on key topics, contextualised with current literature, are summarised in this review article, with the aim of aiding ongoing research into the disease processes of COPD and the development of biomarkers to aid clinical management. Under certain conditions, eosinophils can be recruited to the lung, and increasing evidence supports a role for eosinophilic inflammation in some patients with COPD. Infiltration of eosinophils across the bronchial vascular epithelium into the airways is promoted by the actions of immunoregulatory cells, cytokines and chemokines, where eosinophil-mediated inflammation is driven by the release of proinflammatory mediators. Multiple studies and two meta-analyses suggest peripheral blood eosinophils may correlate positively with an increased likelihood of exacerbation reduction benefits of ICS in COPD. The studies, however, vary in design and duration and by which eosinophil levels are viewed as predictive of an ICS response. Generally, the response was seen when eosinophil levels were 100–300 cells/µL (or higher), levels which are traditionally viewed within the normal range. Some success with interleukin-5-targeted therapy suggests that the eosinophilic phenotype may be a treatable trait. The use of biomarkers could help to stratify treatment for COPD—the goal of which is to improve patient outcomes. Some evidence supports eosinophils as a potential biomarker of a treatable trait in COPD, though it is still lacking and research is ongoing. A unified consensus and a practical, accessible and affordable method of utilising any biomarker for COPD was thought to be of most importance. Challenges around its utilisation may include presenting a clear and pragmatic rationale for biomarker-driven therapy, guidance on ICS withdrawal between primary and secondary care and a lack of financial incentives supporting broad application in clinical practice. Future treatments should, perhaps, be more targeted rather than assuming the primary disease label (COPD or asthma) will define treatment response.

Abstract
Although nanoscaled metal-organic frameworks (nanoMOFs) are promising drug carriers, their appropriate formulation remains almost unexplored and basically restricted to intravenous routes. Lungs, beneficiating from a large absorption surface and low enzymatic presence, are a very attractive target for both local and systemic delivery. However, pulmonary nanoMOF formulation is a pending and defying task. Thus, we propose a pioneer nanoMOF-based microsphere system as a potential platform for pulmonary administration. A biocompatible nanoMOF was successfully encapsulated in mannitol by a simple and continuous spray-drying technique. Upon intratracheal administration to rats, the resulting formulation, exhibiting optimal properties (i.e., homogeneity, size, density, and spray-drying process yield), was able to release the intact nanoMOF carrier uniformly along the lungs, reaching the bronchioles and alveoli.

Abstract
Chronic obstructive pulmonary disease (COPD) is characterized by abnormal inflammation and impaired airway immunity, providing an opportunistic platform for nontypeable Haemophilus influenzae (NTHi) infection. In this context, therapies targeting not only overactive inflammation without significant adverse effects, but also infection are of interest. Increasing evidence suggests that polyphenols, plant secondary metabolites with anti-inflammatory and antimicrobial properties, may be protective. Here, a Cistus salviifolius plant extract containing quercetin, myricetin, and punicalagin was shown to reduce NTHi viability. Analysis of these polyphenols revealed that quercetin has a bactericidal effect on NTHi, does not display synergies, and that bacteria do not seem to develop resistance. Moreover, quercetin lowered NTHi airway epithelial invasion through a mechanism likely involving inhibition of Akt phosphorylation, and reduced the expression of bacterially-induced proinflammatory markers il-8, cxcl-1, il-6, pde4b, and tnfα. We further tested quercetin’s effect on NTHi murine pulmonary infection, showing a moderate reduction in bacterial counts and significantly reduced expression of proinflammatory genes, compared to untreated mice. Quercetin administration during NTHi infection on a zebrafish septicemia infection model system showed a bacterial clearing effect without signs of host toxicity. In conclusion, this study highlights the therapeutic potential of the xenohormetic molecule quercetin against NTHi infection.

Abstract
INTRODUCTION Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) brings a serious impact on patients' quality of life, and has extremely high morbidity and mortality worldwide. Although there are many therapies being developed to alleviate symptoms and reduce mortality, a few studies have supported which treatment method is the best. Traditional Chinese medicine (TCM) has shown good potential in the prevention and treatment of AECOPD, especially in terms of supplementation and reduction of dosage and adverse effect of Western medicine. The purpose of this study is to compare the effectiveness of combination of TCM and Western medicine with conventional therapy alone for AECOPD, and to ensure whether the combined therapy may reduce the use of systemic glucocorticoid in AECOPD without influencing efficacy. METHODS AND ANALYSIS A multicentre, randomised, double-blind, placebo-controlled study was conducted to enrol a total of 360 eligible patients who will be randomised into integrated Chinese and Western medicine group A, B and Western standard Medicine group C. After 5 days of intervention and 1 month of follow-up, the efficacy and safety of Xin Jia Xuan Bai Cheng Qi Decoction in patients with AECOPD will be observed. The results of evaluation indicators include: clinical symptoms, biochemical indicators such as blood gas analysis, inflammatory markers, hospitalisation time, TCM syndrome evaluation, biological indicators such as airway, intestinal flora sequencing. ETHICS AND DISSEMINATION This trail has been approved by the Ethics Committee of China-Japan Friendship Hospital. The results will be disseminated in international peer-reviewed journals and be presented in academic conferences. The results will also be disseminated to patients by telephone, inquiring on patient's poststudy health status during the follow-up. TRIAL REGISTRATION NUMBER ChiCTR1800016915.

[PMID: 31572533 PMCID: PMC6755452 DOI: 10.3892/etm.2019.7898] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2019] [Accepted: 07/30/2019] [Indexed: 12/14/2022] Open
Abstract
Short-term efficacy and safety of prednisone in herpes zoster and the effect on IL-6 and IL-10 were investigated. A total of 125 patients (aged 40–70 years) with acute infective herpes zoster who were admitted to Daqing Oilfield General Hospital were selected and divided into 3 groups according to different treatment methods: low-dose (n=44), middle-dose (n=42) and high-dose (n=39) groups. The therapeutic effect, visual analogue scale (VAS) pain score, pain relieving and disappearing time, herpes stopping and disappearing time, incrustation and decrustation time, and incidence of adverse reactions in the three groups were recorded. The changes of IL-6 and IL-10 levels in the peripheral blood of patients before and after treatment were detected by enzyme-linked immunosorbent assay (ELISA) in order to analyze their relationship with pain degree and the time of symptom remission and subsidence. There were no significant differences in cure rate, significant effective rate, effective rate, ineffective rate and total effective rate among the three groups (P>0.05). The pain relieving and disappearing time in the middle-dose group were shorter than those in the low- and high-dose groups (P<0.05). The levels of IL-6 and IL-10 showed no statistical differences in the 3 groups before treatment (P>0.05). Pearson correlation analysis showed that IL-6 was positively correlated with VAS pain score, pain relieving and disappearing time, herpes stopping and disappearing time, incrustation and decrustation time (P<0.05), while IL-10 was negatively correlated with the above indicators (P<0.05). In conclusion, middle-dose prednisone has similar short-term efficacy to high-dose prednisone in the treatment of herpes zoster, but with lower complication and higher safety. IL-6 and IL-10 are closely related to the pain degree and the time of symptom remission and subsidence, which may provide a reference for clinical evaluation of the therapeutic effect of patients with herpes zoster.

Int J Chron Obstruct Pulmon Dis 2019; 14:1267-1280. [PMID: 31354256 PMCID: PMC6572750 DOI: 10.2147/copd.s207775] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2019] [Accepted: 05/17/2019] [Indexed: 12/17/2022] Open
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.
