Abstract
Novel pharmacotherapies introduce additional options to providers and patients in how to best treat chronic obstructive pulmonary disease (COPD). Emerging data question the role of inhaled corticosteroids in COPD treatment, particularly as combination dual bronchodilator pharmacotherapies demonstrate robust results. For those maximized on pharmacotherapy with continued dyspnea or exacerbations or both, emerging bronchoscopic procedures may offer additional therapy in select patients. This review focuses on data supporting the use of novel ultra bronchodilators, particularly in combination, and on the role for inhaled corticosteroid withdrawal and new bronchoscopic procedures.

Abstract
Chronic obstructive pulmonary disease (COPD) kills more than 3 million people worldwide every year. Despite progress in the treatment of symptoms and prevention of acute exacerbations, few advances have been made to ameliorate disease progression or affect mortality. A better understanding of the complex disease mechanisms resulting in COPD is needed. Smoking cessation programmes, increasing physical activity, and early detection and treatment of comorbidities are further key components to reduce the burden of the disease. However, without a global political and economic effort to reduce tobacco use, to regulate environmental exposure, and to find alternatives to the massive use of biomass fuel, COPD will remain a major health-care problem for decades to come.

Abstract
Severe emphysema patients who have been treated with endobronchial coils have been shown to initially benefit, but slowly decline in the years thereafter. Re-treating a patient with endobronchial coils could potentially lead to new improvements and may again reduce the rate of further decline. To our knowledge, until now, no results are published about patients who are re-treated. The primary aim of this study is to investigate the safety and feasibility of re-treating severe emphysema patients with endobronchial coils, using the PneumRx coil system. Furthermore, as secondary aim, we will evaluate the efficacy of re-treating these patients. Patients who at least 2 years ago were treated with endobronchial coils and responded clinically meaningful to this treatment were included in the study and re-treated. Safety was evaluated by the number of reported adverse events. Efficacy was evaluated 6 months after re-treatment, and measured by the change in quality of life, exercise capacity and pulmonary function testing. Eight patients were re-treated at a median of 1382 days (range 849-1545) after initial coil treatment with a median additional of 12 (10-15) coils per patient. During treatment, and until 6 months of follow-up, no unexpected adverse events occurred. Quality of life, exercise capacity and lung function did not change significantly 6 months after re-treatment. The results of this pilot study suggest that re-treating patients with endobronchial coils is feasible and safe. However, larger studies are needed to confirm these results and to investigate the efficacy and thus the clinical relevance.

Abstract
BACKGROUND Alpha-1 antitrypsin deficiency (AATD) is a rare genetic condition predisposing individuals to chronic obstructive pulmonary disease (COPD). The treatment is generally extrapolated from COPD unrelated to AATD; however, most COPD trials exclude AATD patients; thus, this study sought to systematically review AATD-specific literature to assist evidence-based patient management. METHODS Standard review methodology was used with meta-analysis and narrative synthesis (PROSPERO-CRD42015019354). Eligible studies were those of any treatment used in severe AATD. Randomized controlled trials (RCTs) were the primary focus; however, case series and uncontrolled studies were eligible. All studies had ≥10 participants receiving treatment or usual care, with baseline and follow-up data (>3 months). Risk of bias was assessed appropriately according to study methodology. RESULTS In all, 7,296 studies were retrieved from searches; 52 trials with 5,632 participants met the inclusion criteria, of which 26 studies involved alpha-1 antitrypsin augmentation and 17 concerned surgical treatments (largely transplantation). Studies were grouped into four management themes: COPD medical, COPD surgical, AATD specific, and other treatments. Computed tomography (CT) density, forced expiratory volume in 1 s, diffusing capacity of the lungs for carbon monoxide, health status, and exacerbation rates were frequently used as outcomes. Meta-analyses were only possible for RCTs of intravenous augmentation, which slowed progression of emphysema measured by CT density change, 0.79 g/L/year versus placebo (P=0.002), and associated with a small increase in exacerbations 0.29/year (P=0.02). Mortality following lung transplant was comparable between AATD- and non-AATD-related COPD. Surgical reduction of lung volume demonstrated inferior outcomes compared with non-AATD-related emphysema. CONCLUSION Intravenous augmentation remains the only disease-specific therapy in AATD and there is evidence that this slows decline in emphysema determined by CT density. There is paucity of data around other treatments in AATD. Treatments for usual COPD may not be as efficacious in AATD, and further studies may be required for this disease group.

Abstract
Bronchoscopic interventions are valuable adjuncts to the pharmacologic therapy for chronic obstructive pulmonary disease (COPD). But different phenotypes of COPD patients showed different clinical responses to the same or similar therapy. The optimal selection of bronchoscopic interventions for COPD patients also needs to be based on the phenotypes. According to the different phenotypes, novel interventional pulmonology techniques which were used for COPD treatments in daily clinical practice or clinical trials have been described extensively throughout our current review.

Abstract
BACKGROUND In the recent years, a variety of bronchoscopic lung volume reduction (BLVR) procedures have emerged that may provide a treatment option to participants suffering from moderate to severe chronic obstructive pulmonary disease (COPD). OBJECTIVES To assess the effects of BLVR on the short- and long-term health outcomes in participants with moderate to severe COPD and determine the effectiveness and cost-effectiveness of each individual technique. SEARCH METHODS Studies were identified from the Cochrane Airways Group Specialised Register (CAGR) and by handsearching of respiratory journals and meeting abstracts. All searches are current until 07 December 2016. SELECTION CRITERIA We included randomized controlled trials (RCTs). We included studies reported as full text, those published as abstract only and unpublished data, if available. DATA COLLECTION AND ANALYSIS Two independent review authors assessed studies for inclusion and extracted data. Where possible, data from more than one study were combined in a meta-analysis using RevMan 5 software. MAIN RESULTS AeriSealOne RCT of 95 participants found that AeriSeal compared to control led to a significant median improvement in forced expiratory volume in one second (FEV1) (18.9%, interquartile range (IQR) -0.7% to 41.9% versus 1.3%, IQR -8.2% to 12.9%), and higher quality of life, as measured by the St Georges Respiratory Questionnaire (SGRQ) (-12 units, IQR -22 units to -5 units, versus -3 units, IQR -5 units to 1 units), P = 0.043 and P = 0.0072 respectively. Although there was no significant difference in mortality (Odds Ratio (OR) 2.90, 95% CI 0.14 to 62.15), adverse events were more common for participants treated with AeriSeal (OR 3.71, 95% CI 1.34 to 10.24). The quality of evidence found in this prematurely terminated study was rated low to moderate. Airway bypass stentsTreatment with airway bypass stents compared to control did not lead to significant between-group changes in FEV1 (0.95%, 95% CI -0.16% to 2.06%) or SGRQ scores (-2.00 units, 95% CI -5.58 units to 1.58 units), as found by one study comprising 315 participants. There was no significant difference in mortality (OR 0.76, 95% CI 0.21 to 2.77), nor were there significant differences in adverse events (OR 1.33, 95% CI 0.65 to 2.73) between the two groups. The quality of evidence was rated moderate to high. Endobronchial coilsThree studies comprising 461 participants showed that treatment with endobronchial coils compared to control led to a significant between-group mean difference in FEV1 (10.88%, 95% CI 5.20% to 16.55%) and SGRQ (-9.14 units, 95% CI -11.59 units to -6.70 units). There were no significant differences in mortality (OR 1.49, 95% CI 0.67 to 3.29), but adverse events were significantly more common for participants treated with coils (OR 2.14, 95% CI 1.41 to 3.23). The quality of evidence ranged from low to high. Endobronchial valvesFive studies comprising 703 participants found that endobronchial valves versus control led to significant improvements in FEV1 (standardized mean difference (SMD) 0.48, 95% CI 0.32 to 0.64) and scores on the SGRQ (-7.29 units, 95% CI -11.12 units to -3.45 units). There were no significant differences in mortality between the two groups (OR 1.07, 95% CI 0.47 to 2.43) but adverse events were more common in the endobronchial valve group (OR 5.85, 95% CI 2.16 to 15.84). Participant selection plays an important role as absence of collateral ventilation was associated with superior clinically significant improvements in health outcomes. The quality of evidence ranged from low to high. Intrabronchial valvesIn the comparison of partial bilateral placement of intrabronchial valves to control, one trial favoured control in FEV1 (-2.11% versus 0.04%, P = 0.001) and one trial found no difference between the groups (0.9 L versus 0.87 L, P = 0.065). There were no significant differences in SGRQ scores (MD 2.64 units, 95% CI -0.28 units to 5.56 units) or mortality rates (OR 4.95, 95% CI 0.85 to 28.94), but adverse events were more frequent (OR 3.41, 95% CI 1.48 to 7.84) in participants treated with intrabronchial valves. The lack of functional benefits may be explained by the procedural strategy used, as another study (22 participants) compared unilateral versus partial bilateral placement, finding significant improvements in FEV1 and SGRQ when using the unilateral approach. The quality of evidence ranged between moderate to high. Vapour ablationOne study of 69 participants found significant mean between-group differences in FEV1 (14.70%, 95% CI 7.98% to 21.42%) and SGRQ (-9.70 units, 95% CI -15.62 units to -3.78 units), favouring vapour ablation over control. There was no significant between-group difference in mortality (OR 2.82, 95% CI 0.13 to 61.06), but vapour ablation led to significantly more adverse events (OR 3.86, 95% CI 1.00 to 14.97). The quality of evidence ranged from low to moderate. AUTHORS' CONCLUSIONS Results for selected BLVR procedures indicate they can provide significant and clinically meaningful short-term (up to one year) improvements in health outcomes, but this was at the expense of increased adverse events. The currently available evidence is not sufficient to assess the effect of BLVR procedures on mortality. These findings are limited by the lack of long-term follow-up data, limited availability of cost-effectiveness data, significant heterogeneity in results, presence of skew and high CIs, and the open-label character of a number of the studies.

Abstract
Background Lung volume reduction coil (LVRC) treatment is established in daily endoscopic lung volume reduction routine. The aim of this study was to evaluate the safety and efficacy of LVRC treatment. Patients and methods This was a retrospective analysis of 86 patients (male/female: 40/46, mean age: 64±7 years) with severe COPD and bilateral incomplete fissures. A total of 10 coils were unilaterally implanted in a single lobe, and 28 out of 86 patients were treated bilaterally. At 90-, 180-, and 365-day follow-up, changes in pulmonary function test (PFT), 6-minute walk test (6MWT) and modified Medical Research Council (mMRC) dyspnea scale, as well as possible complications, were recorded. Results At 90 days, the forced expiratory volume in 1 second did improve (P<0.001), but the improvement was not sustained at the 180- and 365-day follow-up (baseline: 0.71±0.21 vs 0.77±0.23 vs 0.73±0.22 vs 0.70±0.18 L). Both vital capacity and residual volume improved significantly (P<0.001) at the 90- and 180-day follow-up, but the improvement was lost after 365 days. Total lung capacity decreased at the 90-day follow-up but returned to baseline values at the 180- and 365-day follow-up. 6MWT (P=0.01) and mMRC (P=0.007) also improved at 90 and 180 days (Δ6MWT of 31±54 and 20±60 m, respectively), but the improvement was also lost at the 365-day follow-up. No significant further improvement was evident at any point in the follow-up after the second procedure. A total of 4 out of 86 patients passed away due to complications. Significant complications in the first 3 months and then at 12 months included the following: severe hemoptysis in 4 (3.5%) and 4 (3.5%) patients, pneumonia requiring hospitalization in 32 (28.1%) and 9 (7.9%) patients and pneumothorax in 7 (6.1%) and 2 (1.7%) patients, respectively. Milder adverse events included self-limited hemoptysis, pneumonias, or COPD exacerbations treated orally. Conclusion LVRC improved PFT, 6MWT and mMRC initially, but the improvement was lost after 365 days. Furthermore, we observed 4 deaths and significant severe complications, which need to be further elucidated.

Abstract
INTRODUCTION The goal of our systematic review and meta-analysis is to examine the therapeutic effectiveness of bronchoscopic lung volume reduction (BLVR), and to compare it with medical management and lung volume reduction surgery. METHODS Variables of interest were absolute change in FEV1, 6MWT, and SGRQ. Meta-analysis was performed for the BLVR modalities with ≥3 trials. Of the 18 shortlisted publications, only valves (four trials; n = 159) and coils (six trials; n = 194) qualified for meta-analysis. To avoid redundant reporting for valves, only the data for intact fissure subjects were analyzed. Outcome data are presented as the mean difference from baseline with 95% confidence interval at 6-months follow-up. RESULTS For BLVR using valves, the pooled mean difference (PMD) for FEV1 was 0.146 L (95% CI 0.111-0.181; p < 0.001), 6MWT was 45.225 meters (95% CI 26.954-63.495; p < 0.001), and SGRQ was -8.825 points (95% CI -14.824 to -2.825; p = 0.004). All the PMDs were statistically significant and higher than their respective minimal clinically important difference (MCID). For BLVR using coils, the PMD for FEV1 was 0.080 L (95% CI 0.057-0.104; p < 0.001), 6MWT was 45.320 meters (95% CI 28.040-62.600; p < 0.001), and SGRQ was -10.570 points (95% CI -13.299 to -7.841; p < 0.001). All three variables showed statistically significant PMDs but that for FEV1 was smaller than the MCID. Data from BLVR modalities with <3 major publications are reviewed in the discussion section. CONCLUSIONS BLVR offers early promise in the palliation of advanced emphysema. Better characterization of patients to identify phenotypes that will derive sustained benefit is needed.

Abstract
Advanced emphysema is a lung disease in which alveolar capillary units are destroyed and supporting tissue is lost. The combined effect of reduced gas exchange and changes in airway dynamics impairs expiratory airflow and leads to progressive air trapping. Pharmacological therapies have limited effects. Surgical resection of the most destroyed sections of the lung can improve pulmonary function and exercise capacity but its benefit is tempered by significant morbidity. This issue stimulated a search for novel approaches to lung volume reduction. Alternative minimally invasive approaches using bronchoscopic techniques including valves, coils, vapour thermal ablation, and sclerosant agents have been at the forefront of these developments. Insertion of endobronchial valves in selected patients could have benefits that are comparable with lung volume reduction surgery. Endobronchial coils might have a role in the treatment of patients with emphysema with severe hyperinflation and less parenchymal destruction. Use of vapour thermal energy or a sclerosant might allow focal treatment but the unpredictability of the inflammatory response limits their current use. In this Review, we aim to summarise clinical trial evidence on lung volume reduction and provide guidance on patient selection for available therapies.

Abstract
Bronchoscopic lung volume reduction (BLVR) is a minimally invasive treatment for severe emphysema, providing treatment options for patients who are unable to undergo lung volume reduction surgery (LVRS) or lung transplantation. Current BLVR techniques include bronchoscopic volume reduction with valve implants, use of a lung volume reduction coil (LVRC), bronchoscopic thermal vapor ablation (BTVA), biological lung volume reduction (BioLVR), and use of airway bypass stents (ABS). To date, several randomized controlled trials of these bronchoscopic therapies have been conducted in patients with emphysema, and bronchoscopic volume reduction with valve implants remains the best approach thus far. Recent studies indicate that BLVR may be of great value in improving lung function, exercise capacity, and quality of life and that BLVR has the potential to replace conventional surgery for patients with severe emphysema. Optimal patient selection and the proper selection of the BLVR technique in accordance with patient characteristics are crucial to the success of BLVR. More multicenter, prospective, randomized controlled trials need to be conducted in the future to optimize the current selection strategy and evaluate the safety, efficiency, and long-term benefit of BLVR techniques.
