Role of fractional exhaled nitric oxide in asthma
Chronic inflammation in asthma is a key feature of the disease and monitoring is an essential component of asthma management. Inflammation is present in both central and peripheral bronchi and can be measured by non invasive markers, such as fractional exhaled nitric oxide (FeNO). FeNO is increased in asthmatics, as compared to normal subjects and is lowered by inhaled corticosteroids (ICS) with a dose-response relationship that is more evident for asthmatic patients with high levels of FeNO. FeNO measuring is easy to be performed in almost all patients including children and can be helpful as a tool contributing to asthma diagnosis and evaluation of the response to antinflammatory therapy with ICS. Smoking affects FeNO measurements and this has to be considered when evaluating patients with asthma who smoke. The different measurement of bronchial and alveolar FeNO can give information on the distribution of inflammation in the bronchial tree and is of particular interest for clinical pharmacology. Nonetheless, the clinical application of FeNO still needs to be clarified but it is clearly nowadays one of the most used non-invasive markers giving information on the inflammatory component of the disease
BDP/formoterol MART asthma exacerbation benefit increases with blood eosinophil level
A number of studies have evaluated the effectiveness of a âMaintenance And Reliever Therapyâ (MART) regimen combining in a single inhaler the rapid-acting, long-acting ÎČ2-agonist (LABA) formoterol fumarate (FF) with an inhaled corticosteroid (ICS) in asthma. Such a regimen is now established for the treatment of moderate-to-severe asthma in adolescents and adults in many guidelines. Furthermore, rescue short-acting ÎČ2-agonists (SABAs) are no longer recommended as sole therapy even for patients with mild asthma, and an ICS/FF combination used as needed is the preferred reliever therapy
Beclomethasone/formoterol fixed combination for the management of asthma: patient considerations
Drugs for asthma and other chronic obstructive diseases of the lungs should be preferably delivered by the inhalation route to match therapeutic effects with low systemic exposure. Inhaled drugs are delivered to the lungs via different devices, mainly metered dose inhalers and dry powder inhalers, each characterized by specific inhaler technique and instructions for use. The patientâdevice interaction is part of the prescribed therapy and can have a relevant impact on adherence and clinical outcomes. The most suitable device should be considered for each patient to assure the correct drug intake and adherence to the prescribed therapy. The development of new drugs/devices in the past decades improved the compliance with inhaler and possibly drug delivery to the bronchi. The present review focuses on the recently developed beclomethasone/formoterol extrafine fixed combination and technical aspects of drug delivery to the lungs in patientâs perspective

Effects of beclomethasone/formoterol fixed combination on lung hyperinflation and dyspnea in COPD patients
Background: Chronic obstructive pulmonary disease (COPD) is a common disease characterized by airflow obstruction and lung hyperinflation leading to dyspnoea and exercise capacity limitation.Objectives: the present study was designed to evaluate whether an extra-fine combination of beclomethasone and formoterol (BDP/F) was effective in reducing air trapping in COPD patients with hyperinflation. Fluticasone salmeterol (FP/S) combination treatment was the active control.Methods: COPD patients with FEV1 <65% and plethysmographic functional residual capacity 120% of predicted were randomized to a double-blind, double-dummy, 12 week, parallel group, treatment with either BDP/F 400/24 \ub5g/day or FP/S 500/100\ub5g/day. Lung volumes were measured with full body plethysmography and dyspnoea was measured with transition dyspnoea index.Results: 18 patients were evaluable for intention to treat. A significant reduction in air trapping and clinically meaningful improvement in transition dyspnoea index total score was detected in the BDP/F group but not in the FP/S group. Functional residual capacity, residual volume (RV) and total lung capacity significantly improved from baseline in the BDP/F group only. With regard to group comparison, a significantly greater reduction in RV was observed with BDP/F vs. FP/S. Conclusion: BDP/F extra-fine combination is effective in reducing air trapping and dyspnoea in COPD patients with lung hyperinflation
The Coexistence of asthma and Chronic Ostructive Pulmonary Disease (COPD): prevalence and risk factors in young, middle-aged and elderly people from the general population
Background: The joint distribution of asthma and chronic obstructive pulmonary disease (COPD) has not been well described. This study aims at determining the prevalence of self-reported physician diagnoses of asthma, COPD and of the asthma-COPD overlap syndrome and to assess whether these conditions share a common set of risk factors.
Methods: A screening questionnaire on respiratory symptoms, diagnoses and risk factors was administered by mail or phone to random samples of the general Italian population aged 20â44 (n = 5163) 45â64 (n = 2167) and 65â84 (n = 1030) in the frame of the multicentre Gene Environment Interactions in Respiratory Diseases (GEIRD) study.
Results: A physician diagnosis of asthma or COPD (emphysema/chronic bronchitis/COPD) was reported by 13% and 21% of subjects aged <65 and 65â84 years respectively. Aging was associated with a marked decrease in the prevalence of diagnosed asthma (from 8.2% to 1.6%) and with a marked increase in the prevalence of diagnosed COPD (from 3.3% to 13.3%). The prevalence of the overlap of asthma and COPD was 1.6% (1.3%â2.0%), 2.1% (1.5%â2.8%) and 4.5% (3.2%â5.9%) in the 20â44, 45â64 and 65â84 age groups. Subjects with both asthma and COPD diagnoses were more likely to have respiratory symptoms, physical impairment, and to report hospital admissions compared to asthma or COPD alone (p<0.01). Age, sex, education and smoking showed different and sometimes opposite associations with the three conditions.
Conclusion: Asthma and COPD are common in the general population, and they coexist in a substantial proportion of subjects. The asthma-COPD overlap syndrome represents an important clinical phenotype that deserves more medical attention and further research.</br
Short term efficacy of nebulized beclomethasone in mild-to-moderate wheezing episodes in pre-school children
<p>Abstract</p> <p>Background</p> <p>Few data are available on the usefulness of short term treatment with low-medium dose of inhaled corticosteroids (ICS) in pre-school children with wheezing exacerbations.</p> <p>Methods</p> <p>To compare the efficacy of one week treatment with 400 ÎŒg b.i.d. nebulized beclomethasone dipropionate (BDP), plus nebulized 2500 ÎŒg prn salbutamol (BDP group), versus nebulized b.i.d. placebo, plus nebulized prn 2500 ÎŒg salbutamol (placebo group), a post-hoc analysis was performed on data obtained in 166 pre-school children with multiple-trigger wheezing, recruited during an acute wheezing episode.</p> <p>Results</p> <p>The percentage of symptom-free days (SFDs) was significantly higher in the BDP group (54.7%) than in the placebo group (40.5%; p = 0.012), with a 35% relative difference. Day-by-day analysis showed that the percentage of SFDs was already higher in the BDP group after 2 days (7.4%), the difference reaching statistical significance at day 6 (12.3%; p = 0.035). Cough score was also reduced in the BDP group (0.11) as compared with the placebo group (0.39; p = 0.048), the difference reaching statistical significance after 5 days of treatment (0.18 and 0.47 respectively; p = 0.047). The mean number of nebulizations per day of prn salbutamol was lower in the BDP group as compared to the placebo group (0.26 and 0.34, respectively), but the difference was not significant (p = 0.366). There were no differences in positive effects of BDP treatment between children with and without risk factors for asthma.</p> <p>Conclusions</p> <p>A 1-week treatment with nebulized BDP and prn salbutamol is effective in increasing SFDs and improving cough in children with wheezing, providing a clinical rationale for the short term use of ICS in episodic wheeze exacerbations in pre-school children.</p> <p>Trial Registration</p> <p>ClinicalTrials.gov (<a href="http://www.clinicaltrials.gov/ct2/show/NCT00497523">NCT00497523</a>)</p
Determinants and impact of suboptimal anthma control in Europe: the international cross-sectional and longitudinal assessment on asthma control (Liaison study)
Background: according to the Global Initiative of Asthma, the aim of asthma treatment is to gain and maintain control. In the INTERNATIONAL CROSS-SECTIONAL AND LONGITUDINAL ASSESSMENT ON ASTHMA CONTROL (LIAISON) study, we evaluated the level of asthma control and quality of life (QoL), as well as their determinants and impact in a population consulting specialist settings. Methods: LIAISON is a prospective, multicentre, observational study with a cross-sectional and a 12-month longitudinal phase. Adults with an asthma diagnosis since at least 6 months, receiving the same asthma treatment in the 4 weeks before enrolment were included. Asthma control was assessed with the 6-item Asthma Control Questionnaire (ACQ) and QoL with the MiniAsthma Quality of Life Questionnaire (MiniAQLQ). Results: overall, 8111 asthmatic patients were enrolled in 12 European countries. Asthma control was suboptimal in 56.5 % of patients and it was associated with poorer asthma-related QoL, higher risk of exacerbations and greater consumption of healthcare resources. Variables associated with suboptimal control were age, gender, obesity, smoking and comorbidities. Major determinants of poor asthma control were seasonal worsening and persisting exposure to allergens/irritants/triggers, followed by treatment-related issues. Conclusions: the cross-sectional phase results confirm that suboptimal control is frequent and has a high individual and economic impact. Trial registration: The clinicaltrials.gov identifier is NCT01567280
