Abstract
Real world data comprise information on health care that is derived from multiple sources outside typical clinical research settings. This review focuses on what real world evidence tells us about problems with the diagnosis of chronic obstructive pulmonary disease (COPD), problems with the initial and follow-up pharmacological and non-pharmacological management, problems with the management of exacerbations and problems with palliative care. Data from real world studies show errors in the management of COPD with delays to diagnosis, lack of confirmation of the diagnosis with spirometry, lack of holistic assessment, lack of attention to smoking cessation, variable adherence to management guidelines, delayed implementation of appropriate interventions, under-recognition of patients at higher risk of adverse outcomes, high hospitalisation rates for exacerbations and poor implementation of palliative care. Understanding that these problems exist and considering how and why they occur is fundamental to developing solutions to improve the diagnosis and management of patients with COPD.

Characterisation of patients with chronic obstructive pulmonary disease initiating single-device inhaled corticosteroids/long-acting β 2-agonist dual therapy in a primary care setting in England. BMJ Open Respir Res 2022; 9:9/1/e001243. [PMID: 36171051 PMCID: PMC9528685 DOI: 10.1136/bmjresp-2022-001243] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Accepted: 08/27/2022] [Indexed: 11/09/2022] Open
Abstract
Introduction Treatment pathways of patients with chronic obstructive pulmonary disease (COPD) receiving single-device dual therapies in England remain unclear. This study describes the characteristics of patients with COPD before initiating treatment with a single-device inhaled corticosteroid/long-acting β2-agonist (ICS/LABA) in primary care in England. Methods This is a retrospective, descriptive study of linked primary and secondary healthcare data (Clinical Practice Research Datalink Aurum, Hospital Episode Statistics). Patients with COPD were indexed on first prescription of fixed-dose, single-device ICS/LABA (June 2015–December 2018). Demographics, clinical characteristics, prescribed treatments, healthcare resource use (HCRU) and direct healthcare costs were assessed over 12 months pre-index. Incident users (indexed on first ever prescription) could be non-triple users (no concomitant long-acting muscarinic antagonist at index); a subset were initial maintenance therapy (IMT) users (no history of pre-index maintenance therapy). Results Overall, 13 451 incident users (non-triple users: 7448, 55.4%; IMT users: 5162, 38.4%) were indexed on beclomethasone dipropionate/formoterol (6122, 45.5%), budesonide/formoterol (2703, 20.1%) or Other ICS/LABA combinations (4626, 34.4%). Overall, 20.8% of incident users had comorbid asthma and 42.6% had ≥1 moderate-to-severe acute exacerbation of COPD pre-index. Baseline characteristics were similar across indexed therapies. At 3 months pre-index, 45.3% and 35.4% of non-triple and IMT users were receiving maintenance treatment. HCRU and direct healthcare costs were similar across indexed treatments. Prescribing patterns varied regionally. Conclusion Patient characteristics, prior treatments, prior COPD-related HCRU and direct healthcare costs were similar across single-device ICS/LABAs in primary care in England. A high proportion of patients were not receiving any respiratory medication pre-index, indicating that prescribing in primary care in England is more closely aligned with national guidelines than global treatment strategies. Comorbid asthma may have influenced prescribing decisions. Less than half of users had preindex exacerbations, suggesting that ICS/LABA is not being prescribed principally based on exacerbation history.

Abstract
Mucus gel constitutes of heavily cross-linked mucin fibers forming a viscoelastic, dense porous network that coats all the exposed epithelia not covered with the skin. The layer provides protection to the underlying gastrointestinal, respiratory, and female reproductive tracts, in addition to the organs such as the surface of eye by trapping the pathogens, irritants, environmental fine particles, and potentially hazardous foreign matter. However, this property of mucus gel poses a substantial challenge for realizing the localized and sustained drug delivery across the mucosal surfaces. The mucus permeating particles that spare the protective properties of mucus gel improve the therapeutic potency of the drugs aimed at the management of diseases, including sexually transmitted infections, lung cancer, irritable bowel disease, degenerative eye diseases and infections, and cystic fibrosis. As such, the mucoadhesive materials conjugated with drug molecules display a prolonged retention time in the mucosal gel that imparts a sustained release of the deliberated drug molecules across the mucosa. The contemporarily developed mucus penetrating materials for drug delivery applications comprise of a finer size, appreciable hydrophilicity, and a neutral surface to escape the entrapment within the cross-inked mucus fibers. Pertaining to the mucus secretion as a first line of defence in respiratory tract in response to the invading physical, chemical, and biological pathogens, the development of mucus penetrating materials hold promise as a stalwart approach for revolutionizing the respiratory drug delivery paradigm. The present review provides an epigrammatic collation of the mucus penetrating/mucoadhesive materials for achieving a controlled/sustained release of the cargo pharmaceutics and drug molecules across the respiratory mucus barrier.

Evaluation of the Clinical Effectiveness of the Salmeterol/Fluticasone Fixed-Dose Combination Delivered via the Elpenhaler ® Device in Greek Patients with Chronic Obstructive Pulmonary Disease and Comorbidities: The AEOLOS Study. J Pers Med 2021; 11:jpm11111159. [PMID: 34834511 PMCID: PMC8621702 DOI: 10.3390/jpm11111159] [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: 10/13/2021] [Revised: 11/02/2021] [Accepted: 11/03/2021] [Indexed: 11/16/2022] Open
Abstract
Background: Chronic Obstructive Pulmonary Disease (COPD) is an inflammatory lung disease characterized by airflow limitation that is not completely reversible. The fixed-dose combination of salmeterol and fluticasone propionate (SFC) has been approved as a treatment for COPD patients with a history of recurrent exacerbations and significant symptoms despite regular bronchodilator therapy. In the present study, we evaluated the change in FEV1, mMRC dyspnea score and satisfaction in COPD patients with at least one comorbidity versus those without comorbidities treated with a fixed-dose SFC via the Elpenhaler® device for 12 months. Methods: A 12-month multicenter prospective, observational study (NCT02978703) was designed. Data were collected during the enrollment visit (V0) and six (V1) and twelve months (V2) after the initiation of treatment with Elpenhaler® SFC. The evaluation of the efficacy of the fixed-dose SFC was performed by assessing the change in lung function and dyspnea as expressed by FEV1 and the mMRC dyspnea scale score in COPD patients with and without comorbidities. Results: In total 1016 patients were enrolled, following usual daily clinical practice. A statistically significant improvement was observed in FEV1 in the total study population between visits V0, V1 and V2, with a change from the baseline at V1 0.15 ± 0.22 L and at V2 0.21 ± 0.25 L (p < 0.0001 for both comparisons). This improvement was exhibited regardless of the COPD severity at the baseline, being more noticeable in GOLD 2020 groups B and C. Similarly, a significant improvement was observed in mMRC dyspnea scale values between successive visits (p < 0.0001). In patients without comorbidities, there was a significant improvement in FEV1 of 0.19 ± 0.24 L at V1 and 0.28 ± 0.27 L at V2 (p < 0.0001 for both comparisons), as well as in the mMRC dyspnea score (p < 0.0001). In patients with at least one comorbidity, a corresponding but smaller improvement in FEV1 was observed (0.11 ± 0.34 L at V1 and 0.20 ± 0.42 L at V2; p < 0.0001 for both comparisons and in the mMRC score (p < 0.0001). In the multiple linear regression analysis BMI, GOLD 2020 groups, mMRC and the presence of comorbidities at the baseline were significant factors for the change of FEV1 between V0 and V2. Conclusions: COPD patients treated for twelve months with SFC via the Elpenhaler® device showed significant improvement in lung function and dyspnea at 6 and 12 months, irrespective of the presence of comorbidities.

Abstract
OBJECTIVE This study aimed to evaluate the level of dyspnoea and the self-management strategies used to alleviate dyspnoea in lung cancer patients with concurrent pneumoconiosis, particularly oxygen therapy and bronchodilator treatment. Furthermore, the authors aimed to determine the factors associated with such self-management and to provide a basis for developing an applicable and safe treatment plan for alleviating dyspnoea. METHOD This study involved a cross-sectional survey. Data were collected using self-report questionnaires from 79 participants between January and July 2016, and self-management strategies were analysed using analysis of variance and multiple logistic regression analysis. RESULTS In terms of the self-management practices employed to relieve dyspnoea, 53.2% of the patients adjusted their oxygen intake and 70.9% used bronchodilators over the prescribed dosage. Adjusting the oxygen intake was not significantly associated with any of the patient characteristics. The factors related to increased bronchodilator use were the presence of comorbidities, cardiopulmonary function, subjective respiratory distress, activities of daily living, and the number of prescribed bronchodilators. CONCLUSION Dyspnoea is a severe critical condition, and urgent management of its clinical symptoms is required. Healthcare professionals who care for patients with lung cancer with pneumoconiosis should pay attention to the dyspnoea and manage it based on clinical evidence. Development of customised, integrated nursing treatment plans is needed to alleviate dyspnoea in patients with complications and chronic dyspnoea who have low daily activity levels.

Effectiveness and Safety of COPD Maintenance Therapy with Tiotropium/Olodaterol versus LABA/ICS in a US Claims Database. Adv Ther 2021; 38:2249-2270. [PMID: 33721209 PMCID: PMC8107175 DOI: 10.1007/s12325-021-01646-5] [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: 11/20/2020] [Accepted: 02/02/2021] [Indexed: 11/18/2022]
Abstract
Introduction In patients with chronic obstructive pulmonary disease (COPD), treatment with long-acting muscarinic antagonist (LAMA)/long-acting β2-agonist (LABA) combination therapy significantly improves lung function versus LABA/inhaled corticosteroid (ICS). To investigate whether LAMA/LABA could provide better clinical outcomes than LABA/ICS, this non-interventional database study assessed the risk of COPD exacerbations, pneumonia, and escalation to triple therapy in patients with COPD initiating maintenance therapy with tiotropium/olodaterol versus any LABA/ICS combination. Methods Administrative healthcare claims and laboratory results data from the US HealthCore Integrated Research Databasesm were evaluated for patients with COPD initiating tiotropium/olodaterol versus LABA/ICS treatment (January 2013–March 2019). Patients were aged at least 40 years with a diagnosis of COPD (but not asthma) at cohort entry. A Cox proportional hazard regression model was used (as-treated analysis) to assess risk of COPD exacerbation, community-acquired pneumonia, and escalation to triple therapy, both individually and as a combined risk of any one of these events. Potential imbalance of confounding factors between cohorts was handled using fine stratification, reweighting, and trimming by exposure propensity score (high-dimensional); subgroup analyses were conducted on the basis of blood eosinophil levels and exacerbation history. Results The total population consisted of 61,985 patients (tiotropium/olodaterol n = 2684; LABA/ICS n = 59,301); after reweighting, the total was 42,953 patients (tiotropium/olodaterol n = 2600; LABA/ICS n = 40,353; mean age 65 years; female 54.5%). Patients treated with tiotropium/olodaterol versus LABA/ICS experienced a reduction in the risk of COPD exacerbations (adjusted hazard ratio 0.76 [95% confidence interval 0.68, 0.85]), pneumonia (0.74 [0.57, 0.97]), escalation to triple therapy (0.22 [0.19, 0.26]), and any one of these events (0.45 [0.41, 0.49]); the combined risk was similar irrespective of baseline eosinophils and exacerbation history. Conclusions In patients with COPD, tiotropium/olodaterol was associated with a lower risk of COPD exacerbations, pneumonia, and escalation to triple therapy versus LABA/ICS, both individually and in combination; the combined risk was reduced irrespective of baseline eosinophils or exacerbation history.

Abstract
Some studies suggest an association between onset and/or poor control of type 2 diabetes mellitus and inhaled corticosteroid (ICS) therapy for chronic obstructive pulmonary disease (COPD), and also between increased fracture risk and ICS therapy; however, study results are contradictory and these associations remain tentative and incompletely characterized. This matched cohort study used two large UK databases (1983–2016) to study patients (≥ 40 years old) initiating ICS or long-acting bronchodilator (LABD) for COPD from 1990–2015 in three study cohorts designed to assess the relation between ICS treatment and (1) diabetes onset (N = 17,970), (2) diabetes progression (N = 804), and (3) osteoporosis onset (N = 19,898). Patients had ≥ 1-year baseline and ≥ 2-year outcome data. Matching was via combined direct matching and propensity scores. Conditional proportional hazards regression, adjusting for residual confounding after matching, was used to compare ICS vs. LABD and to model ICS exposures. Median follow-up was 3.7–5.6 years/treatment group. For patients prescribed ICS, compared with LABD, the risk of diabetes onset was significantly increased (adjusted hazard ratio 1.27; 95% CI, 1.07–1.50), with overall no increase in risk of diabetes progression (adjusted hazard ratio 1.04; 0.87–1.25) or osteoporosis onset (adjusted hazard ratio 1.13; 0.93–1.39). However, the risks of diabetes onset, diabetes progression, and osteoporosis onset were all significantly increased, with evident dose–response relationships for all three outcomes, at mean ICS exposures of 500 µg/day or greater (vs. < 250 µg/day, fluticasone propionate–equivalent). Long-term ICS therapy for COPD at mean daily exposure of ≥ 500 µg is associated with an increased risk of diabetes, diabetes progression, and osteoporosis.

Abstract
BACKGROUND The 2019 Global Initiative for Chronic Obstructive Lung Disease (GOLD) report made recommendations for the assessment, initial and subsequent treatment chronic obstructive pulmonary disease (COPD) based on biomarkers, including blood eosinophil counts. METHODS We evaluated the distribution of UK COPD patients initiating maintenance therapy and established patients by GOLD group, the prevalence of comorbidities and appropriateness of therapy using electronic patient records from the Optimum Patient Care Research Database (OPCRD). Changes in effective GOLD group, therapy and exacerbation rates over the next 2 years were analysed. FINDINGS 11,409 established COPD patients and 699 starting therapy were studied. 44·3%, 25·7%, 13·8% & 16·2% of established COPD patients and 45·2%, 28·5%, 15·7% & 10·6% initiating therapy were in GOLD groups A, B, C & D respectively.The overall proportion in each GOLD group was similar after 2 years but there was substantial movement of patients between groups. Diabetes and cardiovascular disease were the most common comorbidities in all groups in both cohorts.LAMA monotherapy was the commonest initial therapy in all GOLD groups. In both cohorts there was over-treatment with escalation, de-escalation or switching in nearly 50% during follow-up.In both cohorts, exacerbation rates were highest in group D and appeared higher in over-treated patients. INTERPRETATION Most patients are not at risk of exacerbations and co-morbidities are common. Many patients change effective GOLD group and therapy over time. Prescribing is not in accordance with guideline recommendations and many patients still appear over treated.

Abstract
OBJECTIVES Understanding inhaler preferences may contribute to improving adherence in COPD patients and improving long-term outcomes. This study aims to identify and quantify preferences for convenience-related inhaler attributes in French moderate-to-severe COPD patients, with discrete choice experiment (DCE) methodology. METHODS Attributes were defined from a literature search, clinician and patient interviews: shape, dose insertion, dose preparation, dose release, dose confirmation, dose counter and reusability. An online DCE was conducted in respondents with self-reported COPD stage 2-4 recruited through a panel. The study questionnaire included twelve choice scenarios per respondent and questions on patient characteristics, treatment and disease severity. Statistical analyses used a mixed logit regression model with random effects. Utility scores were estimated for four types of inhalers: Inhaler A - soft mist inhaler; Inhaler B - reusable soft mist inhaler; Inhaler C - multi-dose dry powder inhaler; and Inhaler D - single dose dry powder inhaler. RESULTS The study was completed by 153 patients (50 females); respondents were 50.4 years old on average; 13 different inhaler devices were reported. The most preferred inhaler is L-shaped, has dose preparation with capsule insertion and a dose counter, and is reusable. Inhaler profiles A and B had the highest utilities (mean of 1.2533 and 0.9578 respectively) compared to inhaler C (0.6315) and D (0.2200). CONCLUSIONS This study showed statistically significant results that the strongest drivers of preference in French users of inhalation devices for COPD are shape, dose counter and reusability. Convenience-related characteristics are important to patients and should be taken into account by clinicians prescribing these devices.

Trends in the utilisation of COPD therapeutic regimens before and after the introduction of LAMA/LABA combination products: A population-based study. Respir Med 2018; 143:1-7. [PMID: 30261979 DOI: 10.1016/j.rmed.2018.08.001] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2018] [Revised: 07/31/2018] [Accepted: 08/01/2018] [Indexed: 12/11/2022]
Abstract
INTRODUCTION Long-acting muscarinic antagonist/long-acting beta agonist (LAMA/LABA) combination products have recently been introduced. We sought to describe the impact of these products on patterns of chronic obstructive pulmonary disease (COPD) therapy. MATERIALS AND METHODS We used administrative healthcare data from Ontario, Canada, to identify all residents aged ≥ 65 years who were dispensed a product to treat COPD at least once between January 2010 and May 2016, and to calculate the monthly prevalence of use of 11 mutually exclusive therapeutic regimens. We also compared the characteristics of new users of LAMA/LABA and LAMA + LABA regimens. RESULTS Overall use of any COPD regimen remained stable in the year following the formulary listing of LAMA/LABA combination products in May 2015, as did the use of LABA/ICS (most commonly-used regimen). Use of LAMA/LABA and LAMA/LABA + ICS (inhaled corticosteroid) regimens rose rapidly to 283 and 56 users per 100,000 population, respectively, while concurrent falls were seen for LAMA + LABA/ICS (2047 to 1944), LAMA + LABA + ICS (30-19), and LAMA + LABA (103-63). LAMA and LABA monotherapy use declined (1764 to 1669 and 57 to 51, respectively). New users of LAMA/LABA were more likely to be male, urban-dwelling, and to have transitioned from LABA/ICS therapy than new users of LAMA + LABA, and less likely to have transitioned from LAMA or LABA monotherapy, or LAMA + ICS. They were also more likely to have visited a respirologist, and less likely to have been hospitalised, at least once in the preceding 180 days. CONCLUSIONS The introduction of LAMA/LABA combination products led to population-level changes in regimens used for COPD therapy, but no overall increase in long-acting therapy use. New users of LAMA/LABA and LAMA + LABA regimens transitioned to dual LAMA and LABA therapy through different treatment pathways.

A proposal for the withdrawal of inhaled corticosteroids in the clinical practice of chronic obstructive pulmonary disease. Respir Res 2017; 18:198.

Abstract
According to the current clinical practice guidelines for chronic obstructive pulmonary disease (COPD), the addition of inhaled corticosteroids (ICS) to long-acting β2 agonist therapy is recommended in patients with moderate-to-severe disease and an increased risk of exacerbations. However, ICS are largely overprescribed in clinical practice, and most patients are unlikely to benefit from long-term ICS therapy.Evidence from recent randomized-controlled trials supports the hypothesis that ICS can be safely and effectively discontinued in patients with stable COPD and in whom ICS therapy may not be indicated, without detrimental effects on lung function, health status, or risk of exacerbations. This article summarizes the evidence supporting the discontinuation of ICS therapy, and proposes an algorithm for the implementation of ICS withdrawal in patients with COPD in clinical practice.Given the increased risk of potentially serious adverse effects and complications with ICS therapy (including pneumonia), the use of ICS should be limited to the minority of patients in whom the treatment effects outweigh the risks.

Abstract
BACKGROUND Regular use of inhaled corticosteroids (ICS) in patients with obstructive lung diseases has been associated with a higher risk of pneumonia, particularly in COPD. The risk of pneumonia has not been previously evaluated in relation to ICS particle size and dose used. METHODS Historical cohort, UK database study of 23,013 patients with obstructive lung disease aged 12-80 years prescribed extra-fine or fine-particle ICS. The endpoints assessed during the outcome year were diagnosis of pneumonia, acute exacerbations and acute respiratory events in relation to ICS dose. To determine the association between ICS particle size, dose and risk of pneumonia in unmatched and matched treatment groups, logistic and conditional logistic regression models were used. RESULTS 14788 patients were stepped-up to fine-particle ICS and 8225 to extra-fine ICS. On unmatched analysis, patients stepping-up to extra-fine ICS were significantly less likely to be coded for pneumonia (adjusted odds ratio [aOR] 0.60; 95% CI 0.37, 0.97]); experience acute exacerbations (adjusted risk ratio [aRR] 0.91; 95%CI 0.85, 0.97); and acute respiratory events (aRR 0.90; 95%CI 0.86, 0.94) compared with patients stepping-up to fine-particle ICS. Patients prescribed daily ICS doses in excess of 700 mcg (fluticasone propionate equivalent) had a significantly higher risk of pneumonia (OR [95%CI] 2.38 [1.17, 4.83]) compared with patients prescribed lower doses, irrespective of particle size. CONCLUSIONS These findings suggest that patients with obstructive lung disease on extra-fine particle ICS have a lower risk of pneumonia than those on fine-particle ICS, with those receiving higher ICS doses being at a greater risk.

Abstract
Background Global Initiative for Chronic Obstructive Lung Disease (GOLD) global strategy (2015) provides guidance for the treatment of chronic obstructive pulmonary disease (COPD) with different first-choice options per GOLD category without specification. Objectives To evaluate the level of medical experts’ consensus on their preferred first-choice treatment within different COPD categories. Methods A two-round Delphi Panel consisting of 15 questions was completed by Belgian pulmonologists (n=31) and European (n=10) COPD experts. Results Good consensus was reached by both expert groups for long-acting bronchodilators instead of short-acting bronchodilators as first-choice treatment in GOLD A. Single bronchodilation with long-acting muscarinic antagonist (LAMA) was preferred over long-acting β2-agonist (LABA) and LABA/LAMA as first-choice treatment in GOLD B and GOLD C. For GOLD D patients based on the forced expiratory volume in 1 second (FEV1)<50%, a very good consensus was reached for LAMA/LABA as first-choice treatment. For GOLD D patients based on frequent or severe exacerbations, there was a good consensus for LABA/LAMA/inhaled corticosteroids (ICS) as first choice in the Belgian group. According to the European experts, both LABA/LAMA and LABA/LAMA/ICS could be the first choice for these patients. Conclusion Belgian and European experts recommend long-acting bronchodilators as first-choice treatment. Treatment containing ICS was found only appropriate in patients with FEV1<50% and ≥2 moderate exacerbations or 1 severe exacerbation/year.

Abstract
Inhaled corticosteroids (ICSs) belong to the armament for treatment of chronic obstructive pulmonary disease (COPD) and as such, they are widely used in real life. This is a narrative review on evidence-based papers published in the English language listed in Medline between 1990 and March 2016 discussing ICS application in COPD. Recent meta-analyses clearly show that ICSs are able to decrease the rate of exacerbation and to delay the decline of lung function, although they do not prolong life, nor stop the progression of the disease. ICSs are included in guidelines for COPD treatment, exclusively in combination with bronch-15 odilators. However, adverse effects as pneumonia, cataracts, osteoporosis, etc. seem obvious. Newer studies show that patients with COPD are not a homogeneous population, and recently several phenotypes were identified, including asthma-COPD overlap syndrome (ACOS), among others. The efficacy of ICSs seems to be unequal for different subpopulations of patients with COPD and further research is needed to address a personalized approach in the treatment of COPD patients, and to 20 identify predictors for ICS treatment success. Usage of ICSs in patients with COPD needs to be précised especially in patients with COPD without asthma.

Abstract
Tiotropium-olodaterol, formulated in the Respimat soft-mist inhaler, is an inhaled fixed-dose combination (FDC) of a long-acting muscarinic antagonist (LAMA) and a long-acting β2-agonist (LABA), commercialized under the name of Spiolto or Stiolto. The efficacy of tiotropium-olodaterol 5-5 μg once daily in adult patients with COPD was documented in eleven large, multicenter trials of up to 52 weeks duration. Tiotropium-olodaterol 5-5 μg not only improved spirometric values to a significantly greater extent than placebo but also resulted in statistically significant beneficial effects on dyspnea, markers of hyperinflation, use of rescue medication, health-related quality of life, and exercise endurance. Improvements exceeded the minimal clinically important difference (MCID) for forced expiratory volume in 1 second (FEV1), dyspnea, and quality of life. Differences between tiotropium-olodaterol 5-5 μg and the respective monocomponents were statistically significant for FEV1, dyspnea, markers of hyperinflation, use of rescue medication, and health-related quality of life, but did not reach the MCID. However, dual bronchodilatation significantly increased the number of patients who exceeded the MCID for dyspnea and quality of life. Moreover, tiotropium-olodaterol 5-5 μg was significantly more effective than salmeterol-fluticasone (FDC) twice daily at improving pulmonary function. Differences between tiotropium-olodaterol and other LAMA/LABA FDCs were not observed for FEV1 or other efficacy markers. Therefore, tiotropium-olodaterol is a valuable option in the treatment of COPD patients who remain symptomatic under monotherapy.

Abstract
International guidance on chronic obstructive pulmonary disease (COPD) management recommends the use of inhaled corticosteroids (ICS) in those patients at increased likelihood of exacerbation. In spite of this guidance, ICS are prescribed in a large number of patients who are unlikely to benefit. Given the evidence of the risks associated with ICS and the limited indications for their use, there is interest in understanding the effects of withdrawing ICS when prescribed inappropriately. In this review, we discuss the findings of large ICS withdrawal trials, with primary focus on the more recent trials using active comparators. Data from these trials indicate that ICS may be withdrawn without adverse impact on exacerbation risk and patient-reported outcomes in patients with moderate COPD and no history of frequent exacerbations. Considering the safety concerns associated with ICS use, these medications should be withdrawn in patients for whom they are not recommended, while maintaining adequate bronchodilator therapy.

Abstract
Background Management guidelines for chronic obstructive pulmonary disease (COPD) recommend that inhaled corticosteroids (ICS) are prescribed to patients with the most severe symptoms. However, these guidelines have not been widely implemented by physicians, leading to widespread use of ICS in patients with mild-to-moderate COPD. Of particular concern is the potential risk of worsening diabetic control associated with ICS use. Here we investigate whether ICS therapy in patients with COPD and comorbid type 2 diabetes mellitus (T2DM) has a negative impact on diabetic control, and whether these negative effects are dose-dependent. Methods and Findings This was a historical matched cohort study utilising primary care medical record data from two large UK databases. We selected patients aged ≥40 years with COPD and T2DM, prescribed ICS (n = 1360) or non-ICS therapy (n = 2642) between 2008 and 2012. The primary endpoint was change in HbA1c between the baseline and outcome periods. After 1:1 matching, each cohort consisted of 682 patients. Over the 12–18-month outcome period, patients prescribed ICS had significantly greater increases in HbA1c values compared with those prescribed non-ICS therapies; adjusted difference 0.16% (95% confidence interval [CI]: 0.05–0.27%) in all COPD patients, and 0.25% (95% CI: 0.10–0.40%) in mild-to-moderate COPD patients. Patients in the ICS cohort also had significantly more diabetes-related general practice visits per year and received more frequent glucose strip prescriptions, compared with those prescribed non-ICS therapies. Patients prescribed higher cumulative doses of ICS (>250 mg) had greater odds of increased HbA1c and/or receiving additional antidiabetic medication, and increased odds of being above the Quality and Outcomes Framework (QOF) target for HbA1c levels, compared with those prescribed lower cumulative doses (≤125 mg). Conclusion For patients with COPD and comorbid T2DM, ICS therapy may have a negative impact on diabetes control. Patients prescribed higher cumulative doses of ICS may be at greater risk of diabetes progression. Trial Registration ENCePP ENCEPP/SDPP/6804

Abstract
Introduction: The Global initiative for chronic Obstructive Lung Disease (GOLD) recommends treating patients with chronic obstructive pulmonary disease (COPD) based on a combined assessment of symptom severity and airflow limitation and/or exacerbation risk. According to GOLD, patients with mild-to-moderate airflow limitation and distressing symptoms such as dyspnea should be treated with a long-acting beta2-agonist (LABA) or a long-acting muscarinic antagonist (LAMA). If symptoms persist on monotherapy, GOLD recommends a combination of bronchodilators (LABA/LAMA). Methods: We performed a post-hoc analysis of data from two 26-week, prospective clinical trials to investigate the effect of treating patients with moderate-to-severe dyspnea with the once-daily LABA/LAMA combination indacaterol/glycopyrronium (IND/GLY) 110/50 µg compared with placebo, once-daily tiotropium 18 µg, and twice-daily salmeterol/fluticasone propionate (SFC) 50/500 µg. In this analysis, a Baseline Dyspnea Index (BDI) score ≤7 was used to identify dyspneic patients. Results: In dyspneic patients, IND/GLY significantly improved Transition Dyspnea Index (TDI) total scores compared with tiotropium (0.59 units; p<0.05) and SFC (0.97 units; p<0.05), and significantly increased the likelihood of a patient achieving a 1-unit improvement in TDI compared with tiotropium (odds ratio [OR] 1.87; p<0.05). IND/GLY also significantly improved trough forced expiratory volume in 1 second (FEV1) compared with tiotropium and SFC (p<0.001 and p<0.0001, respectively), and significantly reduced rescue medication use compared with tiotropium (p<0.001). Conclusions: Our analysis indicates that IND/GLY provides additional improvements in dyspnea and lung function compared with tiotropium and SFC in dyspneic patients.

The most recent international documents on the management and therapy of chronic obstructive pulmonary disease (COPD) recommend inhaled corticosteroids (ICS) in addition to long-acting bronchodilators as maintenance treatment for patients at high risk of exacerbations, namely patients with forced expiratory volume in 1 s (FEV1) of <50% predicted and/or more than one exacerbation per year. However, ICS are widely used in up to 70% of COPD patients, including those at low risk of exacerbations. In recent years, concerns about the potential adverse effects of this drug category have been raised, and both observational and clinical studies have shown that elderly subjects with COPD treated with ICS are at high risk of developing cataracts and diabetes and more severe and life-threatening conditions such as pneumonia and osteoporotic fractures. Moreover, aging is characterized by memory impairment, decline in muscle strength and body mass impaired coordination, as well as alterations in eyesight and hearing that can impede proper use of devices currently available for ICS administration. Thus, regular use of ICS in more elderly patients with COPD should follow guideline recommendations, be considered with caution, and be based upon carefully weighing up expected benefits with the risk of undesired, adverse effects.

Abstract
Prescribing patterns in chronic obstructive pulmonary disease (COPD) are often inconsistent with published guidelines. This retrospective, observational study utilised data from the Optimum Patient Care Research Database to examine the changes in COPD prescribing patterns over time and to identify predictors of physician treatment choice for patients newly diagnosed with COPD. Initial therapy was defined as the treatment(s) prescribed at or within 1 year before COPD diagnosis. Changes over time were assessed in three cohorts based on the date of diagnosis: (1) 1997-2001; (2) 2002-2006; and (3) 2007-2010. Factors affecting the odds of being prescribed any initial therapy or any initial maintenance therapy were identified by univariable and multivariable logistic regression. The analysis included 20,154 patients, 45% of whom were prescribed an initial regimen containing an inhaled corticosteroid (ICS), whereas 28% received no initial pharmacological treatment. Prescribing of ICS monotherapy decreased over time, as did the proportion of patients receiving no therapy at or within 1 year before diagnosis. Comorbid asthma, a high exacerbation rate, increased symptoms and poor lung function each increased the likelihood of being prescribed any initial therapy or initial maintenance therapy; comorbid asthma and an annual rate of ⩾3 exacerbations were the strongest predictors. In conclusion, our analyses revealed major differences between actual prescribing behaviour and guideline recommendations for patients with newly diagnosed COPD, with many patients receiving no treatment and large numbers of patients receiving ICS-containing regimens. Predictors of initial therapy were identified.

Abstract
BACKGROUND The widespread use of inhaled corticosteroids (ICSs) for COPD treatment has been questioned. Recent studies of weaning some patients with COPD off ICSs found little or no adverse consequences compared with long-acting bronchodilators. It is unclear, however, whether discontinuation of ICSs reduces the elevated risk of pneumonia associated with these drugs. METHODS Using the Quebec health insurance databases, we formed a new-user cohort of patients with COPD treated with ICSs during 1990 to 2005 and followed through 2007 or until a serious pneumonia event, defined as a first hospitalization for or death from pneumonia. A nested case-control analysis of the cohort was used to estimate the rate ratio of serious pneumonia associated with discontinuation of ICS use compared with continued use, adjusted for age, sex, respiratory disease severity, and comorbidity. RESULTS The cohort included 103,386 users of ICSs, of whom 14,020 had a serious pneumonia event during 4.9 years of follow-up (incidence rate, 2.8/100/y). Discontinuation of ICSs was associated with a 37% decrease in the rate of serious pneumonia (rate ratio [RR], 0.63; 95% CI, 0.60-0.66). The risk reduction was rapidly evident, going from 20% in the first month to 50% by the fourth month after discontinuation. The risk reduction was particularly marked with fluticasone (RR, 0.58; 95% CI, 0.54-0.61) but less so with budesonide (RR, 0.87; 95% CI, 0.78-0.97). CONCLUSIONS Discontinuation of ICS use in COPD is associated with a reduction in the elevated risk of serious pneumonia, particularly so with fluticasone.

Abstract
Background Tiotropium + olodaterol has demonstrated improvements beyond lung function benefits in a large Phase III clinical program as a once-daily maintenance treatment for COPD and may be a potential option for the initiation of maintenance treatment in COPD. Despite guideline recommendations that combined long-acting β2-agonists and inhaled corticosteroids should only be used in individuals at high risk of exacerbation, there is substantial use in individuals at lower risk. This raises the question of the comparative effectiveness of this combination as maintenance treatment in this group compared to other combination regimens. Objective The study aimed to assess the effect on lung function of once-daily tiotropium + olodaterol versus twice-daily salmeterol + fluticasone propionate in all participants with Global initiative for chronic Obstructive Lung Disease 2 or 3 (moderate to severe) COPD. Methods This was a randomized, double-blind, double-dummy, four-treatment, complete crossover study in which participants received once-daily tiotropium + olodaterol (5/5 µg and 2.5/5 µg) via Respimat® and twice-daily salmeterol + fluticasone propionate (50/500 µg and 50/250 µg) via Accuhaler® for 6 weeks. The primary end point was change in forced expiratory volume in 1 second (FEV1) area under the curve from 0 hour to 12 hours (AUC0–12) relative to the baseline after 6 weeks. Results Tiotropium + olodaterol 5/5 µg and 2.5/5 µg demonstrated statistically significant improvements in FEV1 AUC0–12 compared to salmeterol + fluticasone propionate (improvements from baseline were 317 mL and 295 mL with tiotropium + olodaterol 5/5 µg and 2.5/5 µg, and 188 mL and 192 mL with salmeterol + fluticasone propionate 50/500 µg and 50/250 µg, respectively). Tiotropium + olodaterol was superior to salmeterol + fluticasone propionate in lung function secondary end points, including FEV1 area under the curve from 0 hour to 24 hours (AUC0–24). Conclusion Once-daily tiotropium + olodaterol in participants with moderate-to-severe COPD provided superior lung function improvements to twice-daily salmeterol + fluticasone propionate. Dual bronchodilation can be considered to optimize lung function in individuals requiring maintenance treatment for COPD.

Abstract
INTRODUCTION Clinical trials have provided some evidence of a favorable effect of inhaled corticosteroids on the frequency of exacerbations and on the quality of life of patients with chronic obstructive pulmonary disease (COPD). In contrast, ICS have little or no impact on lung function decline and on mortality. STATE OF THE ART Inhaled corticosteroids are recommended only in a minority of COPD patients, those with severe disease and repeated exacerbations and probably those with the COPD and asthma overlap syndrome. However, surveys indicate that these drugs are inappropriately prescribed in a large population of patients with COPD. Overtreatment with inhaled corticosteroids exposes these patients to an increased risk of potentially severe side-effects such as pneumonia, osteoporosis, and oropharyngeal candidiasis. Moreover, it represents a major waste of health-care spending. CONCLUSION Primary care physicians as well as pulmonologists should be better aware of the benefits as well as the side-effects and costs of inhaled corticosteroids.

Abstract
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung syndrome, caused by long-term inhalation of noxious gases and particles, which leads to gradual airflow limitation. All health care professionals who care for COPD patients should have full access to high-quality spirometry testing, as postbronchodilator spirometry constitutes the principal method of COPD diagnosis. One out of four smokers 45 years or older presenting respiratory symptoms in primary care, have non-fully reversible airflow limitation compatible with COPD and are mostly without a known diagnosis. Approximately 50.0%-98.3% of patients are undiagnosed worldwide. The majority of undiagnosed COPD patients are isolated at home, are in nursing or senior-assisted living facilities, or are present in oncology and cardiology clinics as patients with lung cancers and coronary artery disease. At this time, the prevalence and mortality of COPD subjects is increasing, rapidly among women who are more susceptible to risk factors. Since effective management strategies are currently available for all phenotypes of COPD, correctly performed and well-interpreted postbronchodilator spirometry is still an essential component of all approaches used. Simple educational training can substantially improve physicians' knowledge relating to COPD diagnosis. Similarly, a physician inhaler education program can improve attitudes toward inhaler teaching and facilitate its implementation in routine clinical practices. Spirometry combined with inhaled technique education improves the ability of predominantly nonrespiratory physicians to correctly diagnose COPD, to adequately assess its severity, and to increase the percentage of correct COPD treatment used in a real-life setting.

Abstract
Fixed dose combination (FDC) dual bronchodilators that co-administer a long acting β2 -adrenoceptor agonist (LABA) and a long acting muscarinic antagonist (LAMA) are a new class of inhaled treatment for chronic obstructive pulmonary disease (COPD). This review focuses on the clinical evidence for the benefit of LABA/LAMA FDCs compared with monocomponent treatments, and also compared with active comparators that are widely used for the treatment of COPD, namely tiotropium and salmeterol-fluticasone. Novel FDC dual bronchodilators include QVA149 and umeclidinium/vilanterol (UMEC/VI). Long term clinical trials show that QVA149 and UMEC/VI are superior to monocomponent therapy in terms of trough forced expiratory volume in 1 s (FEV1), although the FEV1 improvement was limited to approximately 80-90% of the added monocomponent values. This suggests that the effect of combining a LABA and a LAMA is not fully additive. LABA/LAMA FDC were associated with the largest mean changes in symptoms and health status that were above the minimal clinically important difference, in contrast to the monocomponents. Furthermore, these LABA/LAMA FDCs demonstrated superiority over the active comparators tiotropium and salmeterol-fluticasone in terms of trough FEV1 and patient-reported outcomes. LABA/LAMA FDCs offer a simplified means of maximizing bronchodilation for COPD patients, with the improvements in lung function being mirrored by benefits in terms of symptoms and exacerbations. The use of LABA/LAMA FDCs in clinical practice is set to grow and further studies are needed to define their optimal place in treatment guidelines.

Abstract
Chronic obstructive pulmonary disease (COPD) is a serious, yet preventable and treatable, disease. The success of its treatment relies largely on the proper implementation of recommendations, such as the recently released Global Strategy for Diagnosis, Management, and Prevention of COPD (GOLD 2011, of late December 2011). The primary objective of this study was to examine the extent to which GOLD 2011 is being used correctly among Czech respiratory specialists, in particular with regard to the correct classification of patients. The secondary objective was to explore what effect an erroneous classification has on inadequate use of inhaled corticosteroids (ICS). In order to achieve these goals, a multi-center, cross-sectional study was conducted, consisting of a general questionnaire and patient-specific forms. A subjective classification into the GOLD 2011 categories was examined, and then compared with the objectively computed one. Based on 1,355 patient forms, a discrepancy between the subjective and objective classifications was found in 32.8% of cases. The most common reason for incorrect classification was an error in the assessment of symptoms, which resulted in underestimation in 23.9% of cases, and overestimation in 8.9% of the patients' records examined. The specialists seeing more than 120 patients per month were most likely to misclassify their condition, and were found to have done so in 36.7% of all patients seen. While examining the subjectively driven ICS prescription, it was found that 19.5% of patients received ICS not according to guideline recommendations, while in 12.2% of cases the ICS were omitted, contrary to guideline recommendations. Furthermore, with consideration to the objectively-computed classification, it was discovered that 15.4% of patients received ICS unnecessarily, whereas in 15.8% of cases, ICS were erroneously omitted. It was therefore concluded that Czech specialists tend either to under-prescribe or overuse inhaled corticosteroids.
