The Coexistence of Asthma and Chronic Obstructive 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 20–44 (n = 5163) 45–64 (n = 2167) and 65–84 (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 65–84 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%–2.0%), 2.1% (1.5%–2.8%) and 4.5% (3.2%–5.9%) in the 20–44, 45–64 and 65–84 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.

Beclomethasone/formoterol versus budesonide/formoterol combination therapy in asthma

The present study was designed to compare the fixed combination of beclomethasone and formoterol in a hydrofluoroalkane Modulite® (Chiesi Farmaceutici, Parma, Italy) pressurised metered-dose inhaler (pMDI), with a combination of budesonide and formoterol administered via a Turbuhaler® (AstraZeneca, Lund, Sweden) dry powder inhaler (DPI). This was a phase III, multinational, multicentre, double-blind, double-dummy, randomised, two-arm parallel groups, controlled study design. After a 2-week run-in period, 219 patients with moderate-to-severe asthma were randomised to a 12-week treatment with beclomethasone 200 μg plus formoterol 12 μg b.i.d. delivered via a pMDI or budesonide 400 μg plus formoterol 12 μg b.i.d. delivered via a DPI. The analysis of noninferiority on primary outcome, morning peak expiratory flow in the last 2 weeks of treatment, showed no difference between groups. A statistically significant improvement from baseline in lung function, symptoms and rescue medication use was observed in both groups at all time-points. No differences were observed between treatments in either rate of asthma exacerbations or frequency of adverse events. The new fixed combination of beclomethasone and formoterol in hydrofluoroalkane Modulite® pressurised metered-dose inhaler is equivalent to the marketed combination of budesonide and formoterol in terms of efficacy and tolerability profile.

Beclomethasone/formoterol vs fluticasone/salmeterol inhaled combination in moderate to severe asthma

Background:  Recommended treatment for moderate to severe asthma is the combination of an inhaled corticosteroid and a long‐acting beta2‐agonist. The present study was designed to compare a new fixed combination of extrafine beclomethasone and formoterol, with the fixed combination fluticasone and salmeterol.

Real-life prospective study on asthma control in Italy: Cross-sectional phase results

OBJECTIVES To estimate the prevalence of partly controlled and uncontrolled asthmatic patients, to evaluate quality of life and healthcare resource consumption. METHODS Cross-sectional phase followed by a 12-month prospective phase. Asthma Control Test and the EQ-5D were used. RESULTS 2853 adult patients recruited in 56 Hospital Respiratory Units in Italy were evaluated: 64.4% had controlled asthma, 15.8% partly controlled asthma and 19.8% were uncontrolled. The mean (SD) EQ-5D score was 0.86 (0.17) in controlled, 0.75 (0.20) in partly controlled and 0.69 (0.23) in uncontrolled patients (p<0.001 between groups). The number of patients requiring hospitalization or emergency room visits was lower in controlled (1.8% and 1.6%, respectively) than in partly controlled (5.1% and 11.5%) and uncontrolled (6.4% and 18.6%). A combination of an inhaled corticosteroid and a long-acting beta-2 agonist was the reported therapy by 56.0% of patients, with the rate of controlled asthma and improved quality of life being higher in patients on extrafine beclomethasone/formoterol compared to budesonide/formoterol (p<0.05) and fluticasone/salmeterol (p<0.05 for quality of life). CONCLUSIONS Asthma control is achieved in a good proportion of Italian patients. Differences may be detected in a real-life setting in favor of extrafine beclomethasone/formoterol combination.

Asthma control in patients receiving inhaled corticosteroid and long-acting beta2-agonist fixed combinations. A real-life study comparing dry powder inhalers and a pressurized metered dose inhaler extrafine formulation.

BackgroundAlthough patients have more problems using metered dose inhalers, clinical comparisons suggest they provide similar control to dry powder inhalers. Using real-life situations this study was designed to evaluate asthma control in outpatients with moderate to severe persistent asthma and to compare efficacy of fixed combinations of inhaled corticosteroids (ICS) and long acting beta-agonists (LABA).MethodsThis real-life study had a cross-sectional design. Patients using fixed combinations of ICS and LABA had their asthma control and spirometry assessed during regular visits.Results111 patients were analyzed: 53 (47.7%) received maintenance therapy of extrafine beclomethasone-formoterol (BDP/F) pressurized metered dose inhaler (pMDI), 25 (22.5%) fluticasone-salmeterol (FP/S) dry powder inhaler (DPI), and 33 (29.7%) budesonide-formoterol (BUD/F) DPI. Severity of asthma at time of diagnosis, assessed by the treating physician, was comparable among groups. Asthma control was achieved by 45.9% of patients; 38.7% were partially controlled and 15.3% were uncontrolled. In the extrafine BDF/F group, asthma control total score, daytime symptom score and rescue medication use score were significantly better than those using fixed DPI combinations (5.8 ± 6.2 vs. 8.5 ± 6.8; 1.4 ± 1.8 vs. 2.3 ± 2.1; 1.8 ± 2.2 vs. 2.6 ± 2.2; p = 0.0160; p = 0.012 and p = 0.025, respectively) and the mean daily ICS dose were significantly lower.ConclusionspMDI extrafine BDP/F combination demonstrated better asthma control compared to DPIs formulated with larger particles. This could be due to the improved lung deposition of the dose or less reliance on the optimal inhalation technique or both.

Biochemical interaction between effects of beclomethasone dipropionate and salbutamol or formoterol in sputum cells from mild to moderate asthmatics

Background:  Several in vitro studies demonstrate that corticosteroids and long‐acting β2 agonists may have a complementary and synergistic mode of action on the inflammatory processes in asthma.

Regular vs prn nebulized treatment in wheeze preschool children

Background:  International guidelines recommend regular treatment with inhaled glucocorticoids for children with frequent wheezing; however, prn inhaled bronchodilator alone or in combination with glucocorticoid is also often used in practice. We aimed to evaluate whether regular nebulized glucocorticoid plus a prn bronchodilator or a prn nebulized bronchodilator/glucocorticoid combination is more effective than prn bronchodilator alone in preschool children with frequent wheeze.

Inhaled beclometasone dipropionate/formoterol extra-fine fixed combination in the treatment of asthma: evidence and future perspectives.

Background: Combinations of a long-acting β2-agonist (LABA) and an inhaled corticosteroid (ICS) are effective and safe options in asthma management. Objective: To review available data on a recently developed combination of beclometasone dipropionate (BDP) and formoterol (F) given via a pressurized metered-dose inhaler. Methods: Published data on preclinical and clinical studies were reviewed. Results/conclusion: In the treatment of asthma, BDP/F was shown to be at least as effective and well-tolerated as other available combinations of ICS and LABA with the advantage of a better cost effectiveness, and more effective in improving asthma control than BDP and formoterol given via separate inhalers. The extra-fine BDP/F combination appears to be a valuable therapeutic option in the management of asthma.

1-year prospective real life monitoring of asthma control and quality of life in Italy

ObjectivesThe study aimed at prospectively evaluating the evolution of asthma control in Italy, to evaluate the reasons for lack of asthma control, perceived quality of life (QoL) and association with level of asthma control, the impact of pharmacological treatment, the number of exacerbations and the healthcare resource consumption.MethodsPRISMA (PRospectIve Study on asthMA control) was an observational study performed in asthmatic patients including a cross-sectional phase and a 12-month prospective phase. Asthma control was assessed with the Asthma Control Test™ (ACT) and QoL was evaluated with EuroQoL-5D questionnaire filled in and collected during 5 clinic visits together with all the other data.ResultsThe prospective phase included 1017 patients with uncontrolled (55.7%) or partly controlled asthma (44.3%). Out of the 739 patients evaluable after 12 months, 22.2% achieved full asthma control (ACT score = 25) and 58.7% reached a good control (ACT score: 20–24). The improvement in asthma control was associated with improved QoL and reduced hospital visits. The main reasons for lack of asthma control were comorbidities, continued exposure to irritants/triggers and poor adherence to therapy. The frequency of exacerbations was lower in patients with controlled asthma.A fixed combination therapy with an inhaled corticosteroid and a long-acting β2 agonist was reported by 77.0% of patients. A better asthma control and improved QoL were achieved with extrafine beclomethasone/formoterol compared to either budesonide/formoterol or fluticasone/salmeterol.ConclusionsAn improvement in asthma control and QoL can be achieved during a 1-year monitoring in a real life setting. Extrafine beclomethasone/formoterol was associated with significant benefit in terms of asthma control and QoL compared to large-particles combinations.ClinicalTrials.gov number NCT01110460.
