Matching the inhaler to the patient in COPD

Selecting the most appropriate inhalation device from the wide range available is essential for the successful management of patients with chronic obstructive pulmonary disease. Although choice is good for healthcare professionals, knowing which inhaler to prescribe is a complex consideration. Among the key factors to consider are quality of disease control, inhaler technique, inhaler resistance and inspiratory flow, inhaler design and mechanisms of drug delivery, insurance and reimbursement restrictions, and environmental impact. In this article, we offer a simple, practical tool that brings together all these factors and includes hyperlinks to other published resources from the United Kingdom, Belgium, and The Netherlands

A belgian survey on the diagnosis of asthma– COPD overlap syndrome

INTRODUCTION: Patients with chronic airway disease may present features of both asthma and COPD, commonly referred to as asthma-COPD overlap syndrome (ACOS). Recommendations on their diagnosis are diffuse and inconsistent. This survey aimed to identify consensus on criteria for diagnosing ACOS. METHODS: A Belgian expert panel developed a survey on ACOS diagnosis, which was completed by 87 pulmonologists. Answers chosen by >/=70% of survey respondents were considered as useful criteria for ACOS diagnosis. The two most frequently selected answers were considered as major criteria, others as minor criteria. The expert panel proposed a minimal requirement of two major criteria and one minor criterion for ACOS diagnosis. Respondents were also asked which criteria are important for considering inhaled corticosteroids prescription in a COPD patient. RESULTS: To diagnose ACOS in COPD patients, major criteria were "high degree of variability in airway obstruction over time (change in forced expiratory volume in 1 second >/=400 mL)" and "high degree of response to bronchodilators (>200 mL and >/=12% predicted above baseline)". Minor criteria were "personal/family history of atopy and/or IgE sensitivity to >/=1 airborne allergen", "elevated blood/sputum eosinophil levels and/or increased fractional exhaled nitric oxide", "diagnosis of asthma /=10 pack-years for (ex-)smokers"; minor criteria were "lack of response on acute bronchodilator test"; "reduced diffusion capacity"; "limited variability in airway obstruction"; "age >40 years"; "emphysema on chest computed tomography scan". CONCLUSION: Specific criteria were identified that may guide physicians to a more uniform diagnostic approach for ACOS in COPD or asthma patients. These criteria are largely similar to those used to prescribe inhaled corticosteroids in COPD

How to Choose the Right Inhaler Using a Patient-Centric Approach?

There are many different inhaler devices and medications on the market for the treatment of asthma and chronic obstructive pulmonary disease, with over 230 drug-delivery system combinations available. However, despite the abundance of effective treatment options, the achieved disease control in clinical practice often remains unsatisfactory. In this context, a key determining factor is the match or mismatch of an inhalation device with the characteristics or needs of an individual patient. Indeed, to date, no ideal device exists that fits all patients, and a personalized approach needs to be considered. Several useful choice-guiding algorithms have been developed in the recent years to improve inhaler-patient matching, but a comprehensive tool that translates the multifactorial complexity of inhalation therapy into a user-friendly algorithm is still lacking. To address this, a multidisciplinary expert panel has developed an evidence-based practical treatment tool that allows a straightforward way of choosing the right inhaler for each patient

Treatment failure and hospital readmissions in severe COPD exacerbations treated with azithromycin versus placebo - A post-hoc analysis of the BACE randomized controlled trial

Background: In the BACE trial, a 3-month (3 m) intervention with azithromycin, initiated at the onset of an infectious COPD exacerbation requiring hospitalization, decreased the rate of a first treatment failure (TF); the composite of treatment intensification (TI), step-up in hospital care (SH) and mortality. Objectives: (1) To investigate the intervention's effect on recurrent events, and (2) to identify clinical subgroups most likely to benefit, determined from the incidence rate of TF and hospital readmissions. Methods: Enrolment criteria included the diagnosis of COPD, a smoking history of ≥10 pack-years and ≥ 1 exacerbation in the previous year. Rate ratio (RR) calculations, subgroup analyses and modelling of continuous variables using splines were based on a Poisson regression model, adjusted for exposure time. Results: Azithromycin significantly reduced TF by 24% within 3 m (RR = 0.76, 95%CI:0.59;0.97, p = 0.031) through a 50% reduction in SH (RR = 0.50, 95%CI:0.30;0.81, p = 0.006), which comprised of a 53% reduction in hospital readmissions (RR = 0.47, 95%CI:0.27;0.80; p = 0.007). A significant interaction between the intervention, CRP and blood eosinophil count at hospital admission was found, with azithromycin significantly reducing hospital readmissions in patients with high CRP (> 50 mg/L, RR = 0.18, 95%CI:0.05;0.60, p = 0.005), or low blood eosinophil count (<300cells/μL, RR = 0.33, 95%CI:0.17;0.64, p = 0.001). No differences were observed in treatment response by age, FEV1, CRP or blood eosinophil count in continuous analyses. Conclusions: This post-hoc analysis of the BACE trial shows that azithromycin initiated at the onset of an infectious COPD exacerbation requiring hospitalization reduces the incidence rate of TF within 3 m by preventing hospital readmissions. In patients with high CRP or low blood eosinophil count at admission this treatment effect was more pronounced, suggesting a potential role for these biomarkers in guiding azithromycin therapy.

Sternomastoid muscle size and strength in patients with severe chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) imposes a major strain on the respiratory muscle pump, and it is conventionally thought that the inspiratory muscles of the neck adapt to this chronic overload by developing hypertrophy. Yet previous anthropometric studies have shown atrophy of the sternomastoid muscles. To solve this discrepancy, we have measured the cross-sectional area of these muscles by computed tomography. Ten stable patients with severe airflow obstruction (FEV1 = 0.76 +/- 0.12 L) and hyperinflation (FRC = 210 +/- 29% of predicted) and 10 control subjects matched for age, sex, and height were studied. The sternomastoid cross-sectional area in the patients averaged (mean +/- SD) 4.29 +/- 1.48 cm2, and that in the control subjects was 3.96 +/- 0.82 cm2. This small difference could be entirely accounted for by hyperinflation, and it was not statistically significant. Sternomastoid muscle torque in patients was also similar to that in the control subjects. In patients with severe COPD, therefore, the sternomastoid muscles are essentially normal. As a corollary, their frequent prominence on clinical examination is only apparent.Comparative StudyJournal ArticleResearch Support, Non-U.S. Gov'tSCOPUS: ar.jinfo:eu-repo/semantics/publishe

Real-life effectiveness of extrafine beclometasone dipropionate/formoterol in adults with persistent asthma according to smoking status

SummaryBackgroundThe efficacy and safety of extrafine beclomethasone dipropionate 100 μg/formoterol 6 μg (BDP/F HFA) pressurized metered dose inhaler (pMDI) in patients with moderate-to-severe persistent asthma, has been demonstrated in randomised controlled trials (RCTs). The aim of this prospective observational study was to assess real-life effectiveness in terms of asthma control in smoking (most of the time excluded from RCTs) and non-smoking asthmatics.MethodsAdult patients with persistent asthma, in whom treatment with an inhaled corticosteroid/long-acting β2-agonist (ICS/LABA) combination is indicated, were included. Pulmonary function (FEV1%pred or PEF absolute value), Asthma Control Questionnaire (ACQ) and asthma control according to GINA criteria were measured at baseline as well as 2–8 months and >8–14 months after treatment initiation with BDP/F HFA.ResultsOverall, 619 patients were enrolled by 97 investigators. In the effectiveness cohort (N = 568), at baseline, smoking asthmatics (N = 123) had higher ACQ6 (p < 0.0001) and lower asthma control (p = 0.021) than non-smoking asthmatics. Treatment with BDP/F HFA pMDI was associated with significant (p < 0.0001) improvements in pulmonary function (+7.1% in FEV1% pred), ACQ6 (−1.32) and GINA asthma control (improvement of control in 49.8% of patients). Importantly, the same treatment benefits were observed in former or current smokers compared with non-smoking asthmatics. There was a reduction in the dose of ICS from 489 ± 192 μg BDP extrafine equivalents at baseline to 265 ± 125 μg after one year. The drug was well-tolerated.ConclusionThis prospective cohort study demonstrates the real-life effectiveness and safety of BDP/F HFA in adult asthma patients, including smokers, in normal clinical practice
