Abstract
OBJECTIVE To assess the incremental cost-effectiveness of SFC compared with MON for the control of persistent asthma in children. METHODS We conducted an economic evaluation on a 12-week prospective randomized open-label parallel-group comparison of SFC versus MON in children with symptomatic asthma receiving inhaled corticosteroids and short-acting β2-agonists. Asthma-related medication, unscheduled physician contacts and hospitalizations were collected prospectively. The main effectiveness measure was percentage of asthma-controlled week with no short-acting β2-agonist use during the study period. The analysis was conducted from the Mexican healthcare perspective using 2010 unit cost prices, and only direct costs were considered, all costs are reported in US dollar. . The model was made fully probabilistic to reflect the joint uncertainty in the model parameters. RESULTS Over the whole treatment period, the median percentages of asthma-controlled weeks were 83.3% in the SFC group and 66.7% in the MON group (SFC-MON difference, 16.7%; 95% CI, 8.3-16.7; P < 0.001 in favor of SFC). The mean total cost of the SFC regimen was $ 2,323 compared with $ 3,230 for the MON regimen. The SFC was the dominant strategy (both more effective and less expensive) using the SFC was associated with an incremental cost per additional asthma-controlled of $ (5,467). Probabilistic sensitivity analysis tested numerous assumptions about the model cost and efficacy parameters and found that the results were robust to most changes. CONCLUSIONS This analysis demonstrates that, compared with MON, SFC may be cost saving from the Mexican health care perspective for the treatment of pediatric patients with asthma. SFC provided a reduction in the number of severe exacerbations, frequent asthma symptoms and rescue medication use. Incremental cost-effectiveness analysis indicated the dominance of SFC because of both lower costs and greater efficacy.

Abstract
BACKGROUND The purpose of this study was to clarify the association between morphological phenotypes according to the predominance of emphysema and efficacy of long-acting muscarinic antagonist and β(2) agonist bronchodilators in patients with chronic obstructive pulmonary disease (COPD). METHODS Seventy-two patients with stable COPD treated with tiotropium (n = 41) or salmeterol (n = 31) were evaluated for pulmonary function, dynamic hyperinflation following metronome-paced incremental hyperventilation, six-minute walking distance, and St George's Respiratory Questionnaire (SGRQ) before and 2-3 months following treatment with tiotropium or salmeterol. They were then visually divided into an emphysema dominant phenotype (n = 25 in the tiotropium-treated group and n = 22 in the salmeterol-treated group) and an emphysema nondominant phenotype on high-resolution computed tomography, and the efficacy of the two drugs in each phenotype was retrospectively analyzed. RESULTS Tiotropium significantly improved airflow limitation, oxygenation, and respiratory impedance in both the emphysema dominant and emphysema nondominant phenotypes, and improved dynamic hyperinflation, exercise capacity, and SGRQ in the emphysema dominant phenotype but not in the emphysema nondominant phenotype. Salmeterol significantly improved total score for SGRQ in the emphysema phenotype, but no significant effects on other parameters were found for either of the phenotypes. CONCLUSION These findings suggest that tiotropium is more effective than salmeterol for airflow limitation regardless of emphysema dominance, and also can improve dynamic hyperinflation in the emphysema dominant phenotype, which results in further improvement of exercise capacity and health-related quality of life.

Abstract
BACKGROUND Treatment guidelines recommend the use of inhaled long-acting bronchodilators to alleviate symptoms and reduce the risk of exacerbations in patients with moderate-to-very-severe chronic obstructive pulmonary disease (COPD) but do not specify whether a long-acting anticholinergic drug or a β(2)-agonist is the preferred agent. We investigated whether the anticholinergic drug tiotropium is superior to the β(2)-agonist salmeterol in preventing exacerbations of COPD. METHODS In a 1-year, randomized, double-blind, double-dummy, parallel-group trial, we compared the effect of treatment with 18 μg of tiotropium once daily with that of 50 μg of salmeterol twice daily on the incidence of moderate or severe exacerbations in patients with moderate-to-very-severe COPD and a history of exacerbations in the preceding year. RESULTS A total of 7376 patients were randomly assigned to and treated with tiotropium (3707 patients) or salmeterol (3669 patients). Tiotropium, as compared with salmeterol, increased the time to the first exacerbation (187 days vs. 145 days), with a 17% reduction in risk (hazard ratio, 0.83; 95% confidence interval [CI], 0.77 to 0.90; P<0.001). Tiotropium also increased the time to the first severe exacerbation (hazard ratio, 0.72; 95% CI, 0.61 to 0.85; P<0.001), reduced the annual number of moderate or severe exacerbations (0.64 vs. 0.72; rate ratio, 0.89; 95% CI, 0.83 to 0.96; P=0.002), and reduced the annual number of severe exacerbations (0.09 vs. 0.13; rate ratio, 0.73; 95% CI, 0.66 to 0.82; P<0.001). Overall, the incidence of serious adverse events and of adverse events leading to the discontinuation of treatment was similar in the two study groups. There were 64 deaths (1.7%) in the tiotropium group and 78 (2.1%) in the salmeterol group. CONCLUSIONS These results show that, in patients with moderate-to-very-severe COPD, tiotropium is more effective than salmeterol in preventing exacerbations.

Abstract
BACKGROUND Acute lung injury complicates approximately 25-30% of subjects undergoing oesophagectomy. Experimental studies suggest that treatment with beta agonists may prevent the development of acute lung injury by decreasing inflammatory cell infiltration, activation and inflammatory cytokine release, enhancing basal alveolar fluid clearance and improving alveolar capillary barrier function. METHODS/DESIGN The Beta Agonist Lung Injury TrIal (prevention) is a multi-centre, randomised, double blind, placebo-controlled trial. The aim of the trial is to determine in patients undergoing elective transthoracic oesphagectomy, if treatment with inhaled salmeterol 100 mcg twice daily started at induction of anaesthesia and continued for 72 hours thereafter compared to placebo affect the incidence of early acute lung injury and other clinical, resource and patient focused outcomes. The primary outcome will be the development of acute lung injury within 72 hours of oesophagectomy. The trial secondary outcomes are the development of acute lung injury during the first 28 days post operatively; PaO2: FiO2 ratio; the number of ventilator and organ failure free days, 28 and 90 day survival; health related quality of life and resource utilisation. The study aims to recruit 360 patients from 10 UK centres. TRIAL REGISTRATION NUMBER Current Controlled Trials ISRCTN47481946.

Abstract
OBJECTIVES To quantify healthcare use and costs associated with chronic obstructive pulmonary disease (COPD) among patients discharged from a COPD-related hospitalization or emergency department (ED) visit on a regimen of fluticasone propionate-salmeterol combination versus other inhaled maintenance therapies. STUDY DESIGN Retrospective cohort study. METHODS Managed care enrollees with an index hospitalization (with a primary or secondary [ie, in the second position] diagnosis of COPD) or ED visit (with a primary diagnosis of COPD) were identified for placement into study cohorts during a 60-day period following the index date. Time to COPD-related events and healthcare costs were compared during up to 1 year of follow-up between the 2 cohorts. RESULTS The sample comprised 5677 patients (1291 in the fluticasone propionate-salmeterol cohort and 4386 in the other maintenance therapies cohort). The adjusted rate of COPD-related hospitalizations or ED visits was 35% lower in the fluticasone propionate-salmeterol cohort (P <.05). Adjusted COPD-related total (medical plus pharmacy) costs were lower in the fluticasone propionate-salmeterol cohort ($240 vs $279 per patient per month, P <.05), mostly because of lower medical costs ($113 vs $160 per patient per month, P <.05). Pharmacy costs did not differ between fluticasone propionate-salmeterol and other maintenance therapies. Results were similar in the subset of patients 65 years or older. CONCLUSIONS Initiation of fluticasone propionate-salmeterol after discharge from a COPD-related hospitalization or ED visit significantly reduced the risk of a recurrent event during the ensuing months and decreased COPD-related medical costs, without an increase in COPD-related pharmacy costs, in a real-world setting.

Abstract
Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease and responses to therapies are highly variable. The aim of this study was to identify the predictors of pulmonary function response to 3 months of treatment with salmeterol/fluticasone in patients with COPD. A total of 127 patients with stable COPD from the Korean Obstructive Lung Disease (KOLD) Cohort, which were prospectively recruited from June 2005 to September 2009, were analyzed retrospectively. The prediction models for the FEV(1), FVC and IC/TLC changes after 3 months of treatment with salmeterol/fluticasone were constructed by using multiple, stepwise, linear regression analysis. The prediction model for the FEV(1) change after 3 months of treatment included wheezing history, pre-bronchodilator FEV(1), post-bronchodilator FEV(1) change and emphysema extent on CT (R = 0.578). The prediction models for the FVC change after 3 months of treatment included pre-bronchodilator FVC, post-bronchodilator FVC change (R = 0.533), and those of IC/ TLC change after 3 months of treatment did pre-bronchodilator IC/TLC and post-bronchodilator FEV(1) change (R = 0.401). Wheezing history, pre-bronchodilator pulmonary function, bronchodilator responsiveness, and emphysema extent may be used for predicting the pulmonary function response to 3 months of treatment with salmeterol/fluticasone in patients with COPD.

Abstract
Different strategies for disease control in real clinical practice are compared in terms of dynamics of functional parameters in patients with persistent bronchial asthma. This prospective multicentre surveillance study was carried out in 19 Russian clinics using the common protocol. The patients were divided in 3 groups in accordance with the changes of basal antiinflammatory therapy during the study period. Group A--stepwise increase in the extent of combined salmoterol/fluticason therapy, group B--long-term stable-dose salmoterol/fluticason therapy, group C--salmoterol/fluticason therapy with gradual decrease of the dose and/or transition to an alternative variant. Statistical analysis using Statistica 6.0 program included data from 543 patients. The results suggest that the two first modalities increased the level of control (ACT test) and improved characteristics of external respiration throughout the study period. Strategy 3 was associated with a decrease in the external respiration function and the level of control.

Abstract
OBJECTIVE To compare the effectiveness of budesonide/formoterol fumarate dihydrate (BFC) and fluticasone propionate/salmeterol (FSC), two combination inhaled corticosteroid/long-acting beta-agonist (ICS/LABA) products approved for the treatment of chronic obstructive pulmonary disease (COPD) in the US with respect to cost, therapy adherence, and related healthcare utilization. The effectiveness of these two treatments has not previously been compared in a US COPD population. METHODS A retrospective cohort study assessed COPD-related outcomes using administrative claims data among ICS/LABA-naïve patients. Patients initiating BFC were propensity matched to FSC patients. Cost and effectiveness were measured as total healthcare expenditures, exacerbation events (hospitalizations, emergency department visits, or outpatient visits associated with oral corticosteroid or antibiotic prescription fills), and treatment medication adherence. Differences in COPD symptom control were assessed via proxy measure through claims for rescue medications and outpatient encounters. RESULTS Of the 6770 patients (3385 BFC and 3385 FSC), fewer BFC patients had claims for short-acting beta agonists (SABA) (34.7% vs 39.5%; p<0.001) and ipratropium (7.8% vs 9.8%, p<0.005) than FSC patients, but no substantial differences were seen in other clinical outcomes including tiotropium or nebulized SABA claims, COPD-related outpatient visits, or exacerbation events. There were no significant differences in total COPD-related medical costs in the 6-month period after initiation of combination therapy. LIMITATIONS This was a retrospective observational study using claims data and accuracy of COPD diagnoses could not be verified, nor was information available on severity of disease. The results and conclusions of this study are limited to the population observed and the operational definitions of the study variables. CONCLUSIONS For most outcomes of interest, BFC and FSC showed comparable real-world effectiveness.

Abstract
Development new treatments for chronic obstructive respiratory disease is still a far away dream. Naturally, researchers focused on improving efficiency of existent molecules. A new beta-2 adrenergic class was born recently: the ultra-LABA's. First player that was already adopted in current practice is indacaterol. Indacaterol is a beta-2 adrenergic rapidly acting, with an onset of action in 5 minutes, like salbutamol and formoterol but with a sustained bronchodilator effect, that last for 24 hours, like tiotropium. Indacaterol clinical study program, INERGIZE, followed three main directions: prove superiority over placebo, evaluate indacaterol among others established bronchodilators routinely used in COPD management and establish long-term safety profile. In patients with moderate-severe COPD, indacaterol, both 150 and 300 microg showed a rapidly and sustained improvement in pulmonary function, increasing FEV1 with 130-180 ml (p < 0.001) versus placebo (INLIGHT 1). Comparing to salmeterol, there was a superior improvement in FEV1, that starts from day 1 and last unchanged till the end of study (p < 0.01 vs salmeterol; INLIGHT 2). Over 12 mcg formoterol twice daily, 300 microg indacaterolul, once daily showed superiority in improving pulmonary (p < 0.001 vs formoterol; Involve), that is present form day 2, with no ceiling effects over one year, unlike formoterol. As an outcome for secondary objectives, indacaterol proved superior improvement in breathlessness at 12 weeks, (TDI score, p < 0.01 vs formoterol). Regarding exacerbations, indacaterol was at least as effective in reducing exacerbations, as formoterol. Open-label study over tiotropium, INHANCE, compared indacaterol, 150 and 300 microg, with tiotropium, 18 microg, both once daily, for 6 month. At 12 weeks, primary objective for all indacaterol studies, both indacaterol doses showed FEV1 improvement of 180 ml versus 140 ml for tiotropium (p < or = 0.01). % of patients with improvement in TDI score > 1 unit at the end of the study was in favour of indacaterol 300 microg (p < or = 0.01). Authors conclusion was that once daily indacaterol is at least as effective as tiotropium, in its symptoms and health status. The availability of a new once daily bronchodilator, that maximize efficiency of beta-2 adrenergics may provide clinicians with more flexibility in treating COPD, and may increase adherence to treatments for patients.

Abstract
BACKGROUND Despite the use of inhaled corticosteroid (ICS) becoming increasingly widespread, many problems related to asthma management still need to be addressed. One of them, obesity, has been reported to exert a harmful influence on asthma control. However, there have been few reports focusing not only on both obesity and its influence on Japanese asthma patients but also on the Japanese definition of obesity, as defined by the Japan Society for the Study of Obesity (JASSO). AIMS & METHODS The aim of this study was to confirm the influence of obesity, as defined by the JASSO, on asthma management in Japanese asthmatic patients. Using data from the Niigata Asthma Treatment Study Group 2008 questionnaire survey, differences between the "normal" group (18.5 kg/m(2) ≤ BMI <25 kg/m(2)) and the "obese" group (25 kg/m(2) ≤ BMI) were analyzed. RESULTS There was a significantly lower step 1 rate (19.4% v.s. 26.8%) and a higher proportion of patients using inhaled salmeterol (43.6% v.s. 35.8%) and leukotriene receptor antagonist (49.8% v.s. 40.8%) in the obese group relative to the normal group, although there were no significant differences in indicators of asthma control, including asthma control test scores. CONCLUSION This study investigated influences of JASSO-defined obesity on asthma severity and management in a clinical setting in Japan. It is possible that there are strong interactions between asthma and obesity, such as obesity causing decreased ICS therapy efficacy and leukotriene (LT)-related inflammation, although further investigation is necessary.

Abstract
BACKGROUND Asthma is a major health problem and has significant mortality around the world. Although the symptoms can be controlled by drug treatment in most patients, effective low-risk, non-drug strategies could constitute a significant advance in asthma management. An increasing number of patients with asthma are attracted by acupuncture and moxibustion. Therefore, it is of importance that scientific evidence about the efficacy of this type of therapy is regarded. Our past researches suggested heat-sensitive moxibustion might be effective in treatment of asthma. Our objective is to investigate the effectiveness of heat-sensitive moxibustion compared with conventional drug treatment. METHODS/DESIGN This study is comprised of a multi-centre (12 centers in China), randomized, controlled trial with two parallel arms (A: heat-sensitive moxibustion; B: conventional drug). Group A selects heat- sensitive acupoints from the rectangle region which consist of two outer lateral lines of dorsal Bladder Meridian of Foot-Taiyang, and two horizontal lines of BL13(Fei Shu) and BL17 (Ge Shu);6 inch outer the first and second rib gap of anterior chest. Group B treats with fluticasone/salmeterol (seretide). The outcome measures will be assessed over a 3-month period before each clinic visit at days 15, 30, 60, and 90. Follow-up visit will be at 3, 6 months after the last treatment session. Adverse event information will be collected at each clinic visit. DISCUSSION This trial will utilize high quality trial methodologies in accordance with CONSORT guidelines. It may provide evidence for the effectiveness of heat-sensitive moxibustion as a treatment for chronic moderate persistent asthma. Moreover, the result may propose a new type moxibustion to control asthma. TRIAL REGISTRATION The trial is registered at Chinese Clinical Trials Registry: ChiCTR-TRC-09000599.

Abstract
OBJECTIVE To probe a better therapy for chronic persistent asthma. METHODS Thirty-six cases of chronic persistent asthma were randomly divided into a beat-sensitive moxibustion group (17 cases) and a western medication group (19 cases). In heat-sensitive moxibustion group, the sensitization points between Feishu (BL 13) and Geshu (BL 17) were selected with heat-sensitive moxibustion; in western medication group, Seretide inhalant was applied. The patients of both groups were continuously treated for 3 months and the therapeutic effects were evaluated by clinical symptom scores and pulmonary ventilation function test. RESULTS After treatment, the effective rate of 88.2% (15/17) in heat-sensitive moxibustion group was superior to that of 47.4% (9/19) in western medication group (P < 0.05); the clinical symptom scores and pulmonary ventilation function were obviously improved in the two groups, and the heat-sensitive moxibustion group was superior to the western medication group (all P < 0.05). CONCLUSION For chronic persistent bronchial asthma, heat-sensitive moxibustion can improve the clinical symptoms and the pulmonary ventilation function, and it is better than Seretide inhalant.

Abstract
BACKGROUND Long-acting beta-agonist (LABA) therapy improves symptoms in patients whose asthma is poorly controlled by an inhaled glucocorticoid alone. Alternative treatments for adults with uncontrolled asthma are needed. METHODS In a three-way, double-blind, triple-dummy crossover trial involving 210 patients with asthma, we evaluated the addition of tiotropium bromide (a long-acting anticholinergic agent approved for the treatment of chronic obstructive pulmonary disease but not asthma) to an inhaled glucocorticoid, as compared with a doubling of the dose of the inhaled glucocorticoid (primary superiority comparison) or the addition of the LABA salmeterol (secondary noninferiority comparison). RESULTS The use of tiotropium resulted in a superior primary outcome, as compared with a doubling of the dose of an inhaled glucocorticoid, as assessed by measuring the morning peak expiratory flow (PEF), with a mean difference of 25.8 liters per minute (P<0.001) and superiority in most secondary outcomes, including evening PEF, with a difference of 35.3 liters per minute (P<0.001); the proportion of asthma-control days, with a difference of 0.079 (P=0.01); the forced expiratory volume in 1 second (FEV1) before bronchodilation, with a difference of 0.10 liters (P=0.004); and daily symptom scores, with a difference of -0.11 points (P<0.001). The addition of tiotropium was also noninferior to the addition of salmeterol for all assessed outcomes and increased the prebronchodilator FEV1 more than did salmeterol, with a difference of 0.11 liters (P=0.003). CONCLUSIONS When added to an inhaled glucocorticoid, tiotropium improved symptoms and lung function in patients with inadequately controlled asthma. Its effects appeared to be equivalent to those with the addition of salmeterol. (Funded by the National Heart, Lung, and Blood Institute; ClinicalTrials.gov number, NCT00565266.).

Abstract
OBJECTIVE While several studies have examined adherence to controller medications for the treatment of COPD, few systematic reviews have taken the translational step to identifying important and necessary areas for further research. The objective of this study was to review data on the outcomes of adherence to various controller therapies in patients with COPD in an effort to help prescribers understand adherence properties for each therapy. RESEARCH DESIGN AND METHODS This is a systematic review of studies investigating adherence to an array of controller pharmaceutical regimens. The studies were obtained from PubMed during 2008 and 2009 using the following key words: chronic obstructive pulmonary disease, COPD, adherence, controller medication, and persistence. Only articles encompassing adherence or persistence data to controller medications and published after 1990 were utilized. RESULTS After the search results were filtered for only the articles that pertained to adherence or persistence measurements in COPD, 35 articles remained; and finally, discounting those articles not published in English, articles which did not compare treatments for COPD, as well as those which were review articles, ten applicable articles remained. Each of these found low levels of medication adherence and/or persistence among patients receiving medications for COPD. Patients receiving fluticasone/salmeterol (FSC) and tiotropium (TIO) for treatment showed the highest adherence among all controller medications. Patients who were married, older, and white were more likely to adhere to their medications. CONCLUSION Characteristics of the medication used (i.e. dosing schedule, formulation, etc.) as well as patient characteristics affect the adherence/persistence to medications for the treatment of COPD. Further patient education is necessary in order to effectively improve disease management and patient outcomes in COPD. There is a need for future research and educational efforts to improve adherence in COPD and more clearly identify specific behavioral and treatment characteristics associated with specific COPD medications that can facilitate adherence.

Abstract
We tested a set of boron containing arylethanolamine derivatives on the human and guinea pig β(2) adrenoceptor (β(2)AR) 3-D structures by docking methodology. The compound with the highest affinity based on docking analysis, (R)-4-(2-(tert-butylamino)-1-hydroxyethyl)-2-(hydroxymethyl)phenyl hydrogen phenylboronate (boronterol) was synthesized, characterized and tested in guinea pig tracheal rings at basal tone and with histamine-induced contractions. Boronterol was at least eightfold more potent than salbutamol as a smooth muscle relaxant drug (judged by the EC(50) values) and showed a similar maximal relaxant effect as isoproterenol. ICI118,551 showed competitive antagonism on the relaxing effect of boronterol. These results suggest the β(2)AR agonist action of boronterol.

Abstract
BACKGROUND International guidelines recommend long-acting bronchodilators in patients who remain symptomatic despite adequate treatment with short-acting bronchodilators. The purpose of this study is to estimate the effect of tiotropium, a long-acting anticholinergic inhalant, on exacerbation and hospitalisation frequency. METHODS Electronic databases (Medline, Embase, INAHTA, CRD databases, and the Cochrane Library) were searched for randomised controlled trials, comparing tiotropium to placebo, or other bronchodilators. Outcomes were the exacerbation frequency and hospitalisation frequency. Data were pooled using the generic inverse variance method for continuous outcomes. RESULTS Nine studies reported comparisons with placebo (n = 8), ipratropium (short-acting anticholinergic inhalant, n = 1), and salmeterol (long-acting β₂-agonist inhalant, n = 1). Only two studies reported adequate concealment of allocation. Tiotropium reduces the number of exacerbations per patient year by 0.31 (95% CI 0.46- 0.17) compared to placebo, and by 0.23 (95% CI 0.31- 0.15) compared to ipratropium. A significant difference in exacerbation frequency between tiotropium and salmeterol was found (-0.16; 95% CI -0.29 - -0.03) based on approximations of the results of one study.The number of hospitalisations is reduced by 0.04 (95% CI 0.08- 0.01) per patient year compared to placebo and by 0.06 (95% CI -0.09 - -0.03) per patient year compared to ipratropium. CONCLUSIONS Statistically significant but clinically small effects were found for tiotropium compared to placebo and ipratropium. The comparison with salmeterol is significant for exacerbation frequency but not for hospitalisation frequency. Publication bias may be present.
