Barriers and Unmet Educational Needs Regarding Implementation of Medication Adherence Management Across Europe: Insights from COST Action ENABLE. J Gen Intern Med 2024:10.1007/s11606-024-08851-2. [PMID: 38941058 DOI: 10.1007/s11606-024-08851-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Accepted: 05/31/2024] [Indexed: 06/29/2024]
Abstract
BACKGROUND Medication adherence is essential for the achievement of therapeutic goals. Yet, the World Health Organization estimates that 50% of patients are nonadherent to medication and this has been associated with 125 billion euros and 200,000 deaths in Europe annually. OBJECTIVE This study aimed to unravel barriers and unmet training needs regarding medication adherence management across Europe. DESIGN A cross-sectional study was conducted through an online survey. The final survey contained 19 close-ended questions. PARTICIPANTS The survey content was informed by 140 global medication adherence experts from clinical, academic, governmental, and patient associations. The final survey targeted healthcare professionals (HCPs) across 39 European countries. MAIN MEASURES Our measures were barriers and unmet training needs for the management of medication adherence across Europe. KEY RESULTS In total, 2875 HCPs (pharmacists, 40%; physicians, 37%; nurses, 17%) from 37 countries participated. The largest barriers to adequate medication adherence management were lack of patient awareness (66%), lack of HCP time (44%), lack of electronic solutions (e.g., access to integrated databases and uniformity of data available) (42%), and lack of collaboration and communication between HCPs (41%). Almost all HCPs pointed out the need for educational training on medication adherence management. CONCLUSIONS These findings highlight the importance of addressing medication adherence barriers at different levels, from patient awareness to health system technology and to fostering collaboration between HCPs. To optimize patient and economic outcomes from prescribed medication, prerequisites include adequate HCP training as well as further development of digital solutions and shared health data infrastructures across Europe.

Abstract
Poor adherence is an important factor in unstable disease control and treatment failure. There are multiple ways to monitor a patient's adherence, each with their own advantages and disadvantages. The reasons for poor adherence are multi-factorial, inter-related and often difficult to target for improvement. Although practitioners can implement different methods of adherence, the ultimate aim is to improve health outcomes for the individual and the health care system. Asthma is a common airway disease, particularly diagnosed in children, often treated with inhaled corticosteroids and long-acting bronchodilators. Due to the disease's tendency for exacerbations and consequently, when severe will require unscheduled health care utilisation including hospital admissions, considerable research has been done into the effects of medication adherence on asthma control. This review discusses the difficulties in defining adherence, the reasons for and consequences of poor adherence, and the methods of recording and improving adherence in asthma patients, including an in-depth analysis of the uses of smart inhalers.

Abstract
INTRODUCTION Once-daily inhalers have been shown to improve adherence leading to lesser discontinuation compared to twice- or thrice-daily inhalers in management of asthma. Combination of Vilanterol and Fluticasone Furoate (VI/FF) is approved for management of asthma and COPD and is available as a dry powder inhaler. Pressurized-Metered Dose Inhalers (pMDIs) offer ease-of-use and therapy alternatives for patients with low inspiratory flow. This study assessed the efficacy and safety of a new once-daily pMDI containing VI/FF in individuals diagnosed with persistent asthma. METHODS This phase 3, double-blind, randomized controlled study assessed the non-inferiority of VI/FF (12.5 mcg/50 mcg & 12.5 mcg/100 mcg; 2 puffs once-daily) over Formoterol Fumarate and Fluticasone Propionate (FOR/FP, 6 mcg/125 mcg & 6 mcg/250 mcg; 2 puffs twice-daily) in patients with persistent asthma. Primary outcome was change from baseline in trough FEV1 at the end of study (12 weeks). Adverse events and number of exacerbations were used to evaluate safety. RESULTS A total of 330 patients were randomized into VI/FF (165) and FOR/FP (165). Trough FEV1 significantly improved in both the groups at week 12, with a mean difference (VI/FF minus FOR/FP) being 54.75 mL (95% CI, 8.42-101.08 mL, p = 0.02). The low dose VI/FF had similar efficacy to that of low dose FOR/FP and high dose VI/FF had similar efficacy to high dose FOR/FP. No serious adverse events were reported during the study. CONCLUSION Once daily VI/FF pMDI was non-inferior to twice daily FOR/FP pMDI in patients with persistent asthma.

Abstract
The Spanish Guideline on the Management of Asthma, better known by its acronym in Spanish GEMA, has been available for more than 20 years. Twenty-one scientific societies or related groups both from Spain and internationally have participated in the preparation and development of the updated edition of GEMA, which in fact has been currently positioned as the reference guide on asthma in the Spanish language worldwide. Its objective is to prevent and improve the clinical situation of people with asthma by increasing the knowledge of healthcare professionals involved in their care. Its purpose is to convert scientific evidence into simple and easy-to-follow practical recommendations. Therefore, it is not a monograph that brings together all the scientific knowledge about the disease, but rather a brief document with the essentials, designed to be applied quickly in routine clinical practice. The guidelines are necessarily multidisciplinary, developed to be useful and an indispensable tool for physicians of different specialties, as well as nurses and pharmacists. Probably the most outstanding aspects of the guide are the recommendations to: establish the diagnosis of asthma using a sequential algorithm based on objective diagnostic tests; the follow-up of patients, preferably based on the strategy of achieving and maintaining control of the disease; treatment according to the level of severity of asthma, using six steps from least to greatest need of pharmaceutical drugs, and the treatment algorithm for the indication of biologics in patients with severe uncontrolled asthma based on phenotypes. And now, in addition to that, there is a novelty for easy use and follow-up through a computer application based on the chatbot-type conversational artificial intelligence (ia-GEMA).

Abstract
BACKGROUND Indacaterol acetate (IND), a long-acting β2-agonist in combination with mometasone furoate (MF), an inhaled corticosteroid (ICS), is being explored as a once-daily (od) treatment for asthma in children. This study examined the efficacy, safety, and systemic exposure of IND 75 µg and IND 150 µg in children with persistent asthma. METHODS In this Phase IIb, multicenter, randomized, double-blind, parallel-group study, pediatric patients (aged ≥ 6 to < 12 years) with persistent asthma were randomized (1:1) to receive either IND 75 µg od or IND 150 µg od via Breezhaler® in combination with ICS background therapy. The primary endpoint was change from baseline in pre-dose trough forced expiratory volume in one second (FEV1) after two weeks of treatment. RESULTS In total, 80 patients received IND 75 µg (n = 39) or IND 150 µg (n = 41). The study met its primary endpoint; both doses demonstrated improvements in pre-dose trough FEV1 from baseline to Day 14 (mean change [Δ]: 212 mL, IND 75 µg; 171 mL, IND 150 µg). The secondary spirometry parameters (post-dose FEV1 after 1-h, post-dose forced vital capacity; morning and evening peak expiratory flow) also improved. Overall, 36.1% in IND 75 μg group and 25% patients in IND 150 μg group achieved a decrease from baseline in Pediatric Interviewer-administered Asthma Control Questionnaire score of ≥ 0.5 units. A dose-dependent increase in plasma IND concentration was noted between the two groups. Both IND doses demonstrated an acceptable safety profile. CONCLUSIONS Once-daily IND 75 μg and IND 150 μg via Breezhaler® in combination with background ICS therapy provided substantial bronchodilation in children with asthma and were well tolerated. Taken together, these clinical and systemic exposure findings support IND 75 μg as the most appropriate dose for evaluation in Phase III trials in combination with MF in pediatric asthma. TRIAL REGISTRATION ClinicalTrials.gov (NCT02892019; 08-Sep-2016).

Abstract
BACKGROUND Patients with asthma and chronic obstructive pulmonary disease (COPD) may be prescribed once- or twice-daily dosing of controller inhalers. OBJECTIVE To assess differences in controller adherence by dosing schedule and age. METHODS Electronic medication monitors (EMMs) captured the date and time of inhaler actuations over 90 days in patients using the Propeller Health platform. Prescribed inhaler schedule was self-reported. Once- versus twice-daily schedule comparisons were assessed retrospectively using regressions adjusting for age. RESULTS A total of 6294 patients with asthma and 1791 patients with COPD were included. On average, once-daily users had significantly higher median (interquartile range [IQR]) daily adherence than twice-daily users (asthma: 63.3 [IQR: 31.1, 86.7]% vs 50.3 [IQR: 21.1, 78.3]%, P < .001; COPD: 83.3 [IQR: 57.2, 95.6]% vs 64.7 [IQR: 32.8, 88.9]%, P < .001). This pattern persisted in all age groups, with the exception of 4- to 17-year-olds in asthma. The lowest adherence was in the young adult population (18- to 29-year-olds). The percentage of patients who achieved ≥80% adherence was significantly higher among once- versus twice-daily users in asthma (34.3% vs 23.6%, P < .001) and COPD (54.8% vs 38.6%, P < .001). The adjusted odds of once- versus twice-daily users achieving ≥80% adherence was 1.36 (95% confidence interval: 1.19-1.56, P < .001) in asthma and 1.73 (95% confidence interval: 1.38-2.17, P < .001) in COPD. Most once-daily patients with COPD took their medication in the morning versus at night; there was no difference in morning versus afternoon/evening administration in all other asthma and COPD groups. CONCLUSION Patients with asthma and COPD who were prescribed once-daily versus twice-daily medications were more likely to adhere to their inhalers. Patients with COPD had higher adherence than those with asthma, possibly reflecting, in part, the older cohort age. The effect of greater adherence on exacerbations is a topic for future analysis.

Abstract
INTRODUCTION Despite efficacious treatment for chronic obstructive pulmonary disease (COPD), medication adherence remains quite poor, with most estimates based on electronic monitoring devices ranging from 20-30%. This degree of nonadherence represents a significant missed opportunity to realize the benefits of treatment of this disease. AREAS COVERED In this article, we review research on the prevalence of nonadherence among patients with COPD, the association of nonadherence with health outcomes, barriers to adherence in this patient population, and potential interventions. EXPERT OPINION Integrating research into practice involves assessing patients' adherence, identifying modifiable barriers to adherence, open discussion of these barriers with patients, and tailored interventions to address them. These interventions may include treatment of previously unrecognized comorbid disease, providing educational or behavioral interventions, optimizing prescribing strategies, use of adherence aids, or addressing cost and other access barriers. Electronic inhaler monitors are promising interventions for both monitoring and improving adherence. However, remaining concerns about integration into patient care, data management, cost, acceptability, and ethical and privacy issues must be overcome prior to their implementation in clinical practice.

Abstract
Background Recently, the Rome classification was proposed in which objective and readily measurable variables were integrated to mark exacerbations of COPD (ECOPD) severity. The aim of this study is to investigate the distribution of a real-world patient population with hospitalised ECOPD according to the current classification across the newly proposed severity classification. We assume that a significant proportion of hospitalised patients will have a mild or moderate event. Methods The Rome classification was applied to a cohort of 364 COPD patients hospitalised at the Department of Respiratory Medicine of Maastricht University Medical Center (MUMC) with a severe ECOPD. Differences in in-hospital, 30- and 90-day mortality were compared between mild, moderate and severe ECOPD according to the new classification. Moreover, data were stratified by the different severity classes and compared regarding general disease characteristics and clinical parameters. Results According to the Rome proposal, 52 (14.3%) patients had a mild ECOPD, 204 (56.0%) a moderate and 108 (29.7%) a severe ECOPD. In-hospital mortality in mild, moderate and severe events was 3.8%, 6.9% and 13.9%, respectively. Most clinical parameters indicated a significantly worse condition in patients classified in the severe group, compared to those in mild or moderate groups. Conclusion Most of the events, traditionally all classified as severe because of the hospitalisation, were classified as moderate, while almost 15% were mild. The results of this study provide insight into the heterogeneity of hospitalised ECOPD and show that the newly proposed Rome criteria can differentiate between events with different short-term mortality rates.

Abstract
Poor medication adherence is a pervasive issue with considerable health and socioeconomic consequences. Although the underlying reasons are generally understood, traditional intervention strategies rooted in patient-centric education and empowerment have proved to be prohibitively complex and/or ineffective. Formulating a pharmaceutical in a drug delivery system (DDS) is a promising alternative that can directly mitigate many common impediments to adherence, including frequent dosing, adverse effects and a delayed onset of action. Existing DDSs have already positively influenced patient acceptability and improved rates of adherence across various disease and intervention types. The next generation of systems have the potential to instate an even more radical paradigm shift by, for example, permitting oral delivery of biomacromolecules, allowing for autonomous dose regulation and enabling several doses to be mimicked with a single administration. Their success, however, is contingent on their ability to address the problems that have made DDSs unsuccessful in the past.

Abstract
OBJECTIVE Although there is a high risk of drug resistance, empiric treatment is a common approach for pneumonia management. In this respect, it is relevant to know treatment outcomes of patients with pneumonia. This study aimed to assess treatment outcomes and its associated factors among pneumonia patients treated at two public hospitals in Harar, eastern Ethiopia. DESIGN Retrospective follow-up study. SETTING Jugal General Hospital and Hiwot Fana Specialised University Hospital in Harar, eastern Ethiopia. PARTICIPANTS Patients admitted and treated for pneumonia in the two public hospitals in eastern Ethiopia between April 2020 and April 2021. PRIMARY OUTCOME The primary outcome was unfavourable treatment outcome (died or transferred to intensive care unit) for pneumonia patients. RESULTS A total of 693 patients with pneumonia were included in the study. 88 (12.7%) of these patients had an unfavourable treatment outcome, which included 14 (2%) transfers to the intensive care unit and 74 (10.7%) deaths. Patients with comorbidity (adjusted OR, AOR=2.96; 95% CI: 1.47 to 5.97) and with clinical features including abnormal body temperature (AOR=4.03; 95% CI: 2.14 to 7.58), tachycardia (AOR=2.57; 95% CI: 1.45 to 4.55), bradypnoea or tachypnoea (AOR=3.92; 95% CI:1.94 to 7.92), oxygen saturation below 90% (AOR=2.52; 95% CI:1.37 to 4.64) and leucocytosis (AOR=2.78, 95%, CI:1.38 to 5.58) had a significantly increased unfavourable treatment outcome. CONCLUSION We found that nearly one out of eight patients with pneumonia had unfavourable treatment outcomes. It was considerably high among patients with comorbidities and apparent abnormal clinical conditions. Therefore, taking into account regionally adaptable intervention and paying close attention to pneumonia patients admitted with comorbidity and other superimposed abnormal conditions might help improve the treatment outcomes of these populations.

THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2022; 10:2904-2913.e6. [PMID: 35752431 DOI: 10.1016/j.jaip.2022.06.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Revised: 05/23/2022] [Accepted: 06/08/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Treatment guidelines recommend triple therapy for patients with asthma who remain uncontrolled on inhaled corticosteroid/long-acting β2-agonist therapy. Previously, triple therapy was only available via multiple inhalers. Single-inhaler fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) is approved as maintenance treatment for asthma; however, real-world information on adherence and persistence is limited. OBJECTIVE To compare adherence and persistence among adult patients with asthma receiving single-inhaler FF/UMEC/VI versus multiple-inhaler triple therapy (MITT) in the United States. METHODS This retrospective cohort study used IQVIA PharMetrics Plus data to evaluate patients with asthma who initiated once-daily FF/UMEC/VI 100/62.5/25 mcg or MITT between September 18, 2017, and September 30, 2019. Inverse probability weighting and multivariable regression adjusted for differences in characteristics between the FF/UMEC/VI and MITT cohorts. Adherence was assessed using proportion of days covered (PDC) and proportion of patients achieving PDC ≥0.8 and PDC ≥0.5. Non-persistence was identified as a >45-day gap between fills. RESULTS The study included 1396 FF/UMEC/VI and 5115 MITT initiators. Three months after initiation, FF/UMEC/VI users had significantly higher mean PDC versus MITT users (0.68 vs 0.59; P < .001) and 31% more likely to be adherent (PDC ≥0.8; 40.6% vs 31.3%; adjusted risk ratio [95% confidence interval (CI)]: 1.31 [1.13-1.54]; P < .001). Similar patterns were observed at 6 and 12 months post initiation. In addition, FF/UMEC/VI users were 49% more likely to persist at 12 months than MITT users (25.9% vs 15.1%, adjusted hazard ratio [95% CI]: 1.49 [1.39-1.60]; P < .001). CONCLUSIONS Patients with asthma initiating triple therapy with FF/UMEC/VI had significantly better adherence and persistence compared with MITT initiators.

Abstract
In little over a generation, the ingenuity of scientists and clinician researchers has developed inhaled medications and pathway-specific biological agents that control the inflammation and physiology of asthma. Unfortunately, whether it is because of cost or difficulty understanding why or how to use inhaled medications, patients often do not take these medications. The consequences of poor treatment adherence, loss of control and exacerbations, are the same as if the condition remained untreated. Furthermore, poor adherence is difficult to detect without direct measurement. Together this means that poor treatment adherence is easily overlooked and, instead of addressing the cause of poor adherence, additional medicines may be prescribed. In other words, poor treatment adherence is a risk for the patient and adds cost to healthcare systems. In this article, we discuss the rationale for and the delivery of successful interventions to improve medication adherence in asthma. We contextualize these interventions by describing the causes of poor treatment adherence and how adherence is assessed. Finally, future perspectives on the design of new interventions are described.

Adherence to inhaled corticosteroids prescribed once vs twice daily in children with asthma. Ann Allergy Asthma Immunol 2022; 128:423-431.e3.

Abstract
BACKGROUND Suboptimal adherence to inhaled corticosteroids (ICS) is associated with poor asthma control. Adult studies suggest that simplification of ICS regimen leads to better adherence. OBJECTIVE We aimed to determine whether once-daily, compared with twice-daily, ICS dosing was associated with better adherence among children with asthma. METHODS We conducted a retrospective observational study of children with asthma prescribed with either once-daily or twice-daily ICS monotherapy between 2011 and 2019. Our primary adherence outcome was the proportion of prescribed days covered (PPDC)-that is, the number of days for which the drug was dispensed by the pharmacy divided by the number of days for which it was prescribed. The impact of once-daily vs twice-daily ICS regimen on adherence was evaluated using linear multivariable regression analysis adjusting for covariates. Secondary outcomes included the proportion of patients with greater than or equal to 75% adherence analyzed using logistic regression models. RESULTS A total of 232 children (61% boys; mean age of 5.8 [3.6] years) were included; 120 children were prescribed once-daily, and 112 twice-daily, ICS. The median PPDC was 66.8% for the once-daily and 57.9% for the twice-daily group (P = .03). Children prescribed once-daily ICS had a 7.2% (95% confidence interval, 1.3-13.1) greater mean PPDC compared with the twice-daily group and greater odds of having PPDC greater than or equal to 75% (71.4% vs 45.5%; odds ratio, 1.80; 95% confidence interval, 1.01-3.26). CONCLUSION Our findings suggest that once-daily dosing of ICS is associated with better medication adherence than twice-daily dosing. Whether the gain in adherence leads to better asthma control and health outcomes remains to be evaluated.

Abstract
OBJECTIVES To compare median change in morning peak expiratory flow rate (PEFR) and clinical asthma control in children receiving total daily dosage of inhaled budesonide administered either as once-daily or divided twice-daily dose. METHODS It was a randomized, parallel group, open label, noninferiority trial on 80 children aged 5-12 y with mild or moderate well-controlled asthma. Baseline parameters were recorded and subjects received inhaled budesonide either as once-daily or divided twice-daily dose. Primary outcome was median change in morning PEFR. Secondary outcomes included median change in evening and diurnal variation in PEFR, asthma symptom control as per Global Initiative for Asthma, 2017 and Asthma Control Questionnaire, and spirometric measurements taken at the clinic. RESULTS The median [interquartile range (IQR)] increase in morning PEFR was more in children receiving once-daily as compared to those receiving twice-daily inhaled budesonide (by 6:00 L/min; IQR: -44.00-63.00 L/min vs. 4:00 L/min; IQR: -67.50-67.50 L/min, p 0.222; 95% CI: -1.37 to 19.08). Other spirometric variables and symptoms scores were also nonsignificant except median change in evening PEFR which was in favor of twice-daily regimen. CONCLUSION Once-daily administration of inhaled budesonide is noninferior to twice-daily administration of equivalent daily dosage of inhaled budesonide.

Abstract
INTRODUCTION Inhaled corticosteroids (ICS) are known to increase the risk of systemic and local adverse effects, especially with high doses and long-term use. Hence, considerable resources are invested to improve pharmacokinetic/pharmacodynamic (PK/PD) properties of ICS, effective delivery systems and novel combination therapies to enhance the risk-to-benefit ratio of ICS. AREAS COVERED There is an unmet need for new solutions to achieve optimal clinical outcomes with minimal dose of ICS. This paper gives an overview of novel treatment strategies regarding the safety of ICS therapy on the basis of the three most recent molecules introduced to our everyday clinical practice - ciclesonide, mometasone furoate, and fluticasone furoate. Advances in aerosol devices and new areas of inhalation therapy are also discussed. EXPERT OPINION Current progress in improving the risk-to-benefit ratio of ICS through dose and delivery probably established pathways for further developments. This applies both to the improvement of the PK/PD properties of ICS molecules but also includes technical aspects that lead to simplified applicability of the device with simultaneous optimal drug deposition in the lungs. Indubitably, the future of medicine lies not only in the development of new molecules but also in technology and digital revolution.

Abstract
INTRODUCTION Fixed-dose long-acting beta2-agonist (LABA)/inhaled corticosteroid (ICS) combinations and add-on therapies as needed are the mainstay for maintenance therapy in asthma. However, more than 40% of patients have an inadequately controlled disease. The development of triple fixed-dose combinations consisting of long-acting muscarinic antagonist (LAMA)/LABA/ICS has paved the way for a new approach to reach therapeutic goals of an optimal control of symptoms and an effective prevention of future exacerbations. AREAS COVERED A search was conducted on PubMed (MEDLINE), using the MeSH terms [asthma] + [indacaterol] + [glycopyrronium] +[mometasone furoate] + [treatment], until October 2021. Original data from clinical trials, prospective and retrospective studies and reviews were selected. Clinical studies with IND/MF/GLY (Enerzair Breezhaler) are summarized, and its place in current asthma therapy is examined. EXPERT OPINION Triple therapy has been shown to be an effective and safe therapeutic option for asthma patients who remain uncontrolled despite ICS/LABA combination. The recently approved single-inhaler indacaterol/glycopyrronium/mometasone fixed dose combination has demonstrated to significantly reduce exacerbations, improve FEV1, symptoms and quality of life compared to ICS/LABA, including, salmeterol/fluticasone combination. Moreover, once-daily dosing may improve adherence.

Abstract
BACKGROUND Myasthenia gravis (MG) is an autoimmune disease involving the neuromuscular junction. Myasthenic crisis (MC), which is characterized by respiratory failure and the requirement of mechanical ventilation in patients with MG, is still a medical emergency despite the decrease in mortality with the advances in acute management. Hemogram is a cost-effective test for evaluating hematological complications and systemic inflammation, and hemogram data have been used to predict various clinical outcomes of several diseases. The relationship between hemogram and MG has been discussed, but the role of hemogram data in predicting the prognosis of MC patients has not been established. METHODS To identify whether hemogram data can predict in-hospital mortality in patients with MC, we retrospectively investigated 188 myasthenic crisis events from the Chang Gung Research Database between April 2001 and March 2019. Demographic and clinical characteristics were collected, as well as hemogram data before intubation and extubation. The endpoints were mortality during mechanical ventilation and mortality after extubation. RESULTS The overall in-hospital mortality rate was 22%. Multivariate logistic regression analysis for predicting mortality during mechanical ventilation showed that old age at MC onset (OR = 1.039, p = 0.022), moderate-to-severe anemia (OR = 5.851, p = 0.001), and extreme leukocytosis (OR = 5.659, p = 0.022) before intubation were strong predictors of mortality, while acute management with plasma exchange or double-filtration plasmapheresis (PE/DFPP) significantly decreased mortality (OR = 0.236, p = 0.012). For predicting mortality after extubation, moderate-to-severe anemia before extubation (OR = 8.452, p = 0.017) and non-treated with disease-modifying therapy before MC (OR = 5.459, p = 0.031) were crucial predictive factors. CONCLUSION This study demonstrated that both old age at MC onset and moderate-to-severe anemia are important predictors of in-hospital mortality in patients with MC, and extreme leukocytosis is another crucial predictor of mortality during mechanical ventilation. The suggested mechanism is that anemia-induced hypoxia may enhance the release of proinflammatory cytokines, exacerbate systemic inflammation, and lead to multiple organ dysfunction syndrome and, finally, mortality.

Abstract
Problematic severe asthma remains a significant challenge to manage, accounting for the majority of healthcare utilization among children with asthma. The heterogeneity is recognized and the clinical phenotypes of "difficult-to-treat" asthma (DA) and "severe therapy-resistant asthma" (STRA) help to guide management. Recent evidence supports molecular distinctions between these phenotypes and shows poor correlations between peripheral and airway markers of inflammation, especially in STRA. Airway neutrophils in the context of childhood severe asthma have been explored, but their role in disease causation, protection, or as bystanders remain unknown, and thus, treatment implications are unclear. Several novel management strategies, including once-daily maintenance therapy, single-device maintenance and reliever therapy, and novel biological treatments are being increasingly used for DA and STRA. However, pediatric data for efficacy of novel treatments is scarce, and when available, is restricted to adolescents. The aim of this review is to highlight recent advances in objective biomarkers that aid stratification and management of childhood severe asthma and to highlight gaps in pediatric evidence. Specifically, the urgent need for efficacy studies to improve the management of problematic severe asthma in children younger than 12 years.

Abstract
BACKGROUND The management of medication nonadherence of patients with asthma or chronic obstructive pulmonary disease (COPD) remains challenging. Given the multitude of underlying causes, a personalized approach is required. The Test of Adherence to Inhalers (TAI) can identify reasons for nonadherence, but it does not provide guidance regarding how to act effectively after results. OBJECTIVE To develop a practical, evidence-based decision support toolkit for health care professionals managing adult patients with asthma and/or COPD, by matching TAI-identified adherence barriers to proven effective adherence-enhancing interventions. METHODS We performed a literature review in PubMed and Embase identifying interventions that enhanced medication adherence in adult patients with asthma and/or COPD. Randomized controlled trials published in English with full texts available were included. Effective interventions assessed by the Cochrane risk of bias tool were categorized, matched with specific TAI responses, and developed into a practical TAI Toolkit. The Toolkit was assessed for content and usability (System Usability Scale) by a multidisciplinary group of health care professionals. RESULTS In total, 40 randomized controlled trials were included in the review. Seven effective interventions categories were identified, informing the TAI Toolkit: reminders, educational interventions, motivational strategies, feedback on medication use, shared decision-making, simplifying the medication regimen, and multiple component interventions. Health care professionals rated the TAI Toolkit with a mean System Usability Scale score of 71.4 (range, 57.5-80.0). CONCLUSIONS Adherence can be improved using the different interventions that the TAI Toolkit helps select. The TAI Toolkit was well-received by health care professionals. Further research is required to test its validity, practicality, and effectiveness in practice.

Abstract
Inhaled corticosteroids (ICS) are a mainstay of treatment in eosinophilic asthma. Many studies have explored the dose-response effect of different formulations of ICS through direct or indirect bronchoprovocation testing. Such studies are important for investigating efficacy and identifying the relative potency between formulations. However, lack of consistency in methods and designs has hindered the comparability of study findings. This review discusses current knowledge of the dose-response, or lack thereof, of different formulations of ICS through direct and indirect bronchoprovocation testing. The strengths and weaknesses of past studies inform recommendations for future methodological considerations in this field, such as utilizing a randomized double-blind crossover design, enrolling participants likely to respond to ICS therapy, and carefully selecting treatment durations and washout periods to assess incremental improvement in airway hyperresponsiveness while reducing the likelihood of a carryover effect.

Abstract
In December 2019, a cluster of pneumonia caused by a novel coronavirus (2019-nCoV), officially known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), emerged in Wuhan, Hubei province, China. Cytokine storm is an uncontrolled systemic inflammatory response resulting from the release of large amounts of pro-inflammatory cytokines and chemokines that occurs at phase 3 of viral infection. Such emergence led to the development of many clinical trials to discover efficient drugs and therapeutic protocols to fight with this single-stranded RNA virus. Corticosteroids suppress inflammation of the lungs during the cytokine storm, weaken immune responses, and inhibit the elimination of pathogen. For this reason, in COVID-19 corticosteroid therapy, systemic inhibition of inflammation is observed with a wide range of side effects. The present review discusses the effectiveness of the corticosteroid application in COVID-19 infection and the related side effects of these agents. In summary, a number of corticosteroids, including and especially methylprednisolone and dexamethasone, have demonstrated remarkable efficacy, particularly for COVID-19 patients who underwent mechanical ventilation.

Association of patient weight status with plasma surfactant protein D, a biomarker of alveolar epithelial injury, in children with acute respiratory failure. Pediatr Pulmonol 2020; 55:2730-2736.

Abstract
AIMS AND OBJECTIVES Alveolar epithelial injury is a key determinant of acute respiratory failure (ARF) severity. Plasma surfactant protein D (SP-D), a biomarker of alveolar epithelial injury, is lower in obese adults with ARF compared to their lean peers. We aimed to determine if children with ARF have similar variance in plasma SP-D associated with their weight status on admission. METHODS Plasma SP-D was measured on days 0, 1, or 2 in children (1-18 years) with ARF enrolled in the genetic variation and biomarkers in children with acute lung injury and RESTORE studies. Weight classification (underweight, normal, overweight, and obese) was based on body mass index or weight-for-height z-scores. Associations between weight group and SP-D on each day were tested. RESULTS Inclusion criteria were met in 212 subjects, 24% were obese. There were no differences among weight groups in SP-D levels on days 0 and 1. However, on day 2, there was a statistically significant linear trend for lower SP-D levels as weight increased in both the univariate analysis (P = .02) and when adjusting for age, ethnicity, and diagnosis of pediatric acute respiratory distress syndrome (P = .05). CONCLUSIONS Obesity was associated with lower plasma SP-D levels on day 2 of ARF. This finding may be explained by altered ARF pathogenesis in obese individuals or a reduced incidence of ventilator-induced lung injury.

Abstract
The topic of 24-hour management of COPD is related to day-to-night symptoms management, specific follow-up and patients’ adherence to therapy. COPD symptoms strongly vary during day and night, being worse in the night and early morning. This variability is not always adequately considered in the trials. Night-time symptoms are predictive of higher mortality and more frequent exacerbations; therefore, they should be a target of therapy. During night-time, in COPD patients the supine position is responsible for a different thoracic physiology; moreover, during some sleep phases the vagal stimulation determines increased bronchial secretions, increased blood flow in the bronchial circulation (enhancing inflammation) and increased airway resistance (broncho-motor tone). Moreover, in COPD patients the circadian rhythm may be impaired. The role of pharmacotherapy in this regard is still poorly investigated. Symptoms can be grossly differentiated according to the different phenotypes of the disease: wheezing recalls asthma, while dyspnea is strongly related to emphysema (dynamic hyperinflation) or obstructive bronchiolitis (secretions). Those symptoms may be different targets of therapy. In this regard, GOLD recommendations for the first time introduced the concept of phenotype distinction suggesting the use of inhaled corticosteroids (ICS) particularly when an asthmatic pattern or eosiophilic inflammations are present, and hypothesized different approaches to target symptoms (ie, dyspnea) or exacerbations. Pharmacotherapy should be evaluated and possibly directed on the basis of circadian variations, for instance, supporting the use of twice-daily rapid-action bronchodilators and evening dose of ICS. Recommendations on day and night symptoms monitoring strategies and choice of the specific drug according to patient’s profile are still not systematically investigated or established. This review is the summary of an advisory board on the topic “24-hour control of COPD and role of pharmacotherapy”, held by five pulmonologists, experts in respiratory pathophysiology, pharmacology and sleep medicine. ![]()

Fixed-dose combination of indacaterol/glycopyrronium/mometasone furoate once-daily versus salmeterol/fluticasone twice-daily plus tiotropium once-daily in patients with uncontrolled asthma: A randomised, Phase IIIb, non-inferiority study (ARGON). Respir Med 2020; 170:106021. [PMID: 32843164 DOI: 10.1016/j.rmed.2020.106021] [Citation(s) in RCA: 33] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2020] [Revised: 05/06/2020] [Accepted: 05/10/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND The efficacy and safety of once-daily (o.d.) fixed-dose combination of indacaterol (IND), glycopyrronium (GLY) and mometasone furoate (MF) via Breezhaler® versus concurrent administration of salmeterol/fluticasone (SAL/FLU) twice-daily (b.i.d.) via Accuhaler®+Tiotropium (TIO) o.d. via Respimat® was evaluated in patients with uncontrolled asthma. METHODS Patients (aged ≥18 years), symptomatic (Asthma Control Questionnaire [ACQ]-7 ≥1.5) despite treatment with long-acting β2-agonist/inhaled corticosteroid medium- or high-dose, received IND/GLY/MF high- (150/50/160 μg) or medium-dose (150/50/80 μg) o.d. or SAL/FLU high-dose (50/500 μg) b.i.d.+Tio 5 μg o.d. for 24 weeks. The primary objective was to confirm the non-inferiority of either dose of IND/GLY/MF to SAL/FLU high dose + TIO in terms of Asthma Quality of Life Questionnaire (AQLQ). Additional endpoints: ACQ-7, lung function, health status (St George's Respiratory Questionnaire [SGRQ]), exacerbations, and safety after 24 weeks. RESULTS IND/GLY/MF high- and medium-dose met the primary endpoint, confirming non-inferiority to SAL/FLU high dose + TIO for AQLQ (least square mean treatment difference [Δ]: 0.073 and -0.038, respectively; both p < 0.001). IND/GLY/MF high-dose improved ACQ-7 (Δ: -0.124; p = 0.004), trough FEV1 (Δ: 96 mL; p < 0.001), peak expiratory flow (morning [Δ: 9.56 L/min; p = 0.005], evening [Δ: 9.15 L/min; p = 0.006]) and SGRQ (Δ: -2.00; p = 0.04) versus SAL/FLU high dose + TIO. Improvements in these endpoints were comparable for IND/GLY/MF medium-dose and SAL/FLU high dose + TIO. Adverse events were generally comparable across treatments. CONCLUSIONS IND/GLY/MF high- and medium-dose o.d. via a single inhaler were non-inferior to SAL/FLU high-dose b.i.d. + TIO o.d. via two inhalers for AQLQ. IND/GLY/MF high-dose o.d. improved lung function, asthma control and health status versus SAL/FLU high dose + TIO, while IND/GLY/MF medium-dose had comparable efficacy but at a corresponding lower steroid dose.

Abstract
OBJECTIVE This real-world observational study compared medication adherence and persistence among patients with asthma receiving the once-daily inhaled corticosteroid/long-acting β2-agonist (ICS/LABA) fluticasone furoate/vilanterol (FF/VI) versus the twice-daily ICS/LABAs budesonide/formoterol (B/F) and fluticasone propionate/salmeterol (FP/SAL). METHODS This retrospective cohort study conducted using IQVIATM Health Plan Claims Data included patients with asthma ≥18 years of age initiating ICS/LABA therapy with FF/VI, B/F, or FP/SAL between January 1, 2014 and June 30, 2016 (index date). Patients had ≥12 months and ≥3 months of continuous eligibility pre- and post-index date, respectively. Patients receiving FF/VI were separately matched 1:1 with patients receiving B/F or FP/SAL using propensity score matching (PSM) and multivariable regression to balance baseline covariates between cohorts. The primary endpoint was medication adherence, measured by proportion of days covered (PDC). Secondary endpoints included proportion of patients achieving PDC ≥ 0.5 and PDC ≥ 0.8 and persistence with index medication, measured by time to discontinuation (>45-day gap in therapy). RESULTS After PSM, 3,764 and 3,339 patients receiving FF/VI were matched with patients receiving B/F or FP/SAL, respectively. Mean PDC was significantly higher for FF/VI versus B/F (0.453 vs 0.345; adjusted p < 0.001) and FP/SAL (0.446 vs 0.341; adjusted p < 0.001). The proportion of patients achieving PDC ≥ 0.5 or PDC ≥ 0.8, and treatment persistence were significantly higher for FF/VI versus B/F and FP/SAL (all p < 0.001). CONCLUSIONS In this real-world study, patients initiating FF/VI had better adherence and lower risk of discontinuing treatment versus B/F or FP/SAL, suggesting that once-daily ICS/LABA treatment might improve adherence and persistence compared with twice-daily alternatives.

Abstract
Despite the availability of treatment guidelines and inhaled medications for asthma and chronic obstructive pulmonary disease (COPD), much remains to be done to lessen the burden of these respiratory diseases for patients. The challenge of selecting effective and efficacious drugs for patients is a key focus area for healthcare professionals. Here we discuss the concept of "drivers of effectiveness"- features of a medicine which may increase or decrease its effectiveness in the presence of real-world factors - and highlight the importance of considering these drivers in the early stages of drug development, and exploring their impact in carefully designed pragmatic trials. Using the Salford Lung Studies (SLS) in asthma and COPD as an illustrative example, we discuss various features of the inhaled corticosteroid/long-acting β2-agonist combination, fluticasone furoate/vilanterol (FF/VI), as potential drivers of effectiveness that may have contributed to the improved patient outcomes observed with initiation of FF/VI versus continuation of usual care in the UK primary care setting.

Abstract
Patients with asthma that is uncontrolled despite high intensity medication can present in both primary and specialist care. An increasing number of novel (and expensive) treatments are available for patients who fail conventional asthma therapy, but these may not be appropriate for all such patients. It is essential that a rigorous evaluation process be undertaken for these patients to identify those with biologically severe asthma who will require novel therapies, and those who may improve with control of contributory factors. In this article, we describe three key steps in the diagnostic evaluation process for severe asthma. The first step is confirmation of asthma diagnosis with objective evidence of variable airflow obstruction. The second involves management of contributory factors such as non-adherence, poor inhaler technique, ongoing asthma triggers, and comorbidities. The third step involves phenotyping and endotyping of patients with severe asthma. We provide a practical approach to implementing these measures in both primary and secondary care.

Abstract
OBJECTIVE To describe the prevalence of common barriers to asthma medication adherence and examine associations between patient-reported asthma controller adherence and asthma control, therapy adherence barriers, and asthma management characteristics. METHODS Previously developed asthma-specific tool was pilot tested on a convenience sample of adult patients with persistent asthma. The following data were collected via patient survey: demographic characteristics and comorbidities, adherence, asthma control, and asthma management characteristics. Descriptive and inferential statistics were used to address the study objective. RESULTS The patients (N = 93) were 45.4 (17.2) years of age, and 66.7% were female. The majority had poor (68.8%) adherence, with 61.3% of patients having controlled asthma. There was no significant association between adherence and asthma control. The mean number of barriers for good and poor adherence groups differed significantly: 2.0 ± 1.1 and 5.4 ± 2.4, respectively (P < .0001). Having an asthma action plan (AAP) was the only asthma management characteristic significantly related to adherence. The majority of patients with poor adherence did not have an AAP (76.6%), whereas 81.5% of patients with good adherence did have an AAP (P < 0.0001). CONCLUSIONS The use of this survey tool confirmed presence of asthma-specific barriers, thus using this specialized approach may lead to more effective, targeted counseling in community pharmacy settings.

Abstract
BACKGROUND Although efficacy and safety of fluticasone furoate/vilanterol (FF/VI) and budesonide/formoterol (BUD/F) have been demonstrated in clinical studies, real-world comparisons of utilization have not been performed. OBJECTIVE To compare similar patients with asthma initiating FF/VI or BUD/F on measures of adherence, persistence, and the asthma medication ratio (AMR). METHODS This was a retrospective cohort study of commercial and Medicare Advantage with Part D enrollees initiating FF/VI or BUD/F for asthma. Adult patients (≥18 years) with at least 15-month (12-month preindex and 3-month postindex) continuous enrollment and 1 or more asthma diagnosis code were eligible for the study. Patients with a history of fixed-dose inhaled corticosteroid/long-acting β-agonist and other respiratory disorders (chronic obstructive pulmonary disease, cystic fibrosis, acute respiratory failure) in the baseline period were excluded. Propensity-score matching was used to balance cohorts on baseline characteristics. Logistic regression and Cox-proportional hazard models were used to assess differences. RESULTS A total of 9951 patients met all criteria. After propensity-score matching, 1725 patients were matched in each cohort. Subjects who initiated FF/VI had a significantly higher mean proportion of days covered (P < .001), had 86% greater odds of having a proportion of days covered value of greater than or equal to 0.80 (adjusted odds ratio, 1.86; 95% CI, 1.51-2.30), 26% lower risk of discontinuation (adjusted hazard ratio, 0.74; 95% CI, 0.69-0.79), and 36% greater odds of an AMR of greater than or equal to 0.50 (adjusted odds ratio, 1.36; 95% CI, 1.23-1.50) compared with BUD/F. CONCLUSIONS Adherence and treatment persistence were low in both cohorts; however, patients initiating once-daily FF/VI were more likely to be adherent, have an AMR of greater than or equal to 0.5, and were less likely to discontinue therapy compared with patients initiating twice-daily BUD/F (GlaxoSmithKline Study HO1617302/206482).

Abstract
Introduction There is a paucity of data describing prescribing patterns and adherence to therapy of inhaled corticosteroids (ICS) in combination with long-acting β2-agonists (LABA) in the Japanese population in clinical practice. Methods This was a non-interventional, retrospective, cohort study of patients who were prescribed medication for asthma, using data from the Japan Medical Data Center Claims Database. Data from patients aged ≥ 15 years with a prescription of asthma drugs between December 2014 and October 2015 (Day 0, the index date when asthma medication was initiated) were analysed in 12-month pre-index and post-index periods. Part 1 focused on baseline characteristics and epidemiological outcomes in the pre- and post-index period in the overall asthma population, whereas comparing medication adherence [number of prescribed days per year and proportion of days covered (PDC)] between ICS/LABA-naïve patients treated with once-daily fluticasone furoate/vilanterol (FF/VI) and twice-daily fluticasone propionate/salmeterol (FP/SAL) was the primary endpoint in Part 2. Results Of the available patient data (N = 2,953,652), 28,699 patients were identified as having asthma. ICS/LABA was the main asthma treatment prescribed; 11,167 (38.9%) patients were continuous ICS/LABA users. In ICS/LABA-naïve asthma patients, treatment with once-daily FF/VI was associated with higher medication adherence compared with twice-daily FP/SAL; mean [standard deviation (SD)] number of prescribed days per year was 97.8 (115.9) for FF/VI versus 80.5 (92.7) for FP/SAL (p = 0.04), mean (SD) PDC was 26.7% (31.5) for FF/VI versus 21.9% (24.8) for FP/SAL (p = 0.04). FF/VI was also associated with a lower rate of treatment discontinuation and no difference in use of short-acting beta2-agonists or oral corticosteroids compared with FP/SAL. Conclusions ICS/LABA was the major prescribed asthma treatment in Japan. Medication adherence was greater with FF/VI, which may indicate that patients are more likely to adhere to once-daily FF/VI versus twice-daily FP/SAL.

Abstract
Introduction: Poor adherence to inhaled medication is a commonly encountered problem among children with asthma. However, there is a relatively paucity of data regarding the adherence of children with severe asthma, as well as the merit of any interventions to improve this adherence. Objectives: The aim of this systematic review was to identify the available literature on the rate of adherence and the influence of interventions in improving adherence to controller inhaled medication, in children with severe asthma. Methods: A systematic literature search was performed in MEDLINE/PubMed, Cochrane Library, and Scopus databases. Studies were included in the present review if their target population were children and/or adolescents with severe asthma and presented data on medication adherence before and after a given intervention. Results: A total of seven studies, conducted in USA, Canada, and UK, and published between 2012 and 2018, met the inclusion criteria. Adherence to controller medication was assessed via either objective or subjective measures (questionnaires), or a combination of them. Interventions included communication during pediatric visits and audio-taped medical visits, individualized care programs, electronic monitoring devices, interactive website and peak-flow prediction with feedback. Adherence rates for the baseline (before intervention) or for the control groups ranged from 28 to 67%. In general, there was a significant improvement of adherence after intervention with rates increasing to 49-81%. Conclusion: Adherence rate in children with severe asthma is not satisfactory but it can be improved after proper interventions. Nevertheless, the heterogeneity among adherence assessment tools, and the variety of interventions, in combination with the lack of studies focusing on severe asthma, highlight the need for further research in this field.

Abstract
OBJECTIVE We aimed to demonstrate non-inferiority of once-daily fluticasone furoate/vilanterol 100/25 µg (FF/VI) to twice-daily fluticasone propionate/salmeterol 250/50 µg (FP/SAL) in adults/adolescents with asthma well controlled on inhaled corticosteroid/long-acting β2 agonist (ICS/LABA). METHODS This was a randomized, double-blind, double-dummy, parallel-group, 24-week study (NCT02301975/GSK study 201378). Patients whose asthma met study-defined criteria for control were randomized 1:1:1 to receive FF/VI, FP/SAL or twice-daily FP 250 µg for 24 weeks. Primary endpoint was change from baseline in evening trough forced expiratory volume in 1 second (FEV1). Secondary endpoints included rescue-/symptom-free 24-hour periods. Safety was also assessed. RESULTS The intent-to-treat (ITT) population included 1504 randomized and treated patients (504 FF/VI; 501 FP/SAL; 499 FP); mean age 43.5 years, 64% female. FF/VI demonstrated non-inferiority (using a margin of -100 mL) to FP/SAL for evening trough FEV1 at Week 24 (ITT: 19 mL [95% confidence interval (CI) -11 to 49]; per protocol population [N = 1336]: 6 mL [95% CI -27 to 40]). Improvement in evening trough FEV1 at Week 24 for both FF/VI (123 mL; p < 0.001) and FP/SAL (104 mL; p < 0.001) was greater than FP. FF/VI increased rescue-/symptom-free 24-hour periods by 1.2%/1.2% compared with FP/SAL. All treatments were well tolerated. On-treatment adverse event (AE) rates were 43% to 45% across arms; there were no drug-related serious AEs. CONCLUSIONS FF/VI was non-inferior to FP/SAL for evening trough FEV1 at 24 weeks. These data suggest that patients well controlled on FP/SAL could step across to FF/VI without loss of control.

Abstract
BACKGROUND Once-daily inhaled corticosteroids (ICSs) are widely used as first-line therapy in patients with asthma. OBJECTIVE To compare the efficacy of ICSs administered once daily in the morning or evening as determined by lung function. METHODS Medline, Embase, and the Cochrane Central Register were searched for relevant clinical trials. The primary outcome was lung function assessed as trough forced expiratory volume in 1 second and peak expiratory flow at end point. RESULTS Eight randomized clinical trials involving 1,234 patients were analyzed. The total number of patients treated with once-daily ICS in the morning and evening was 628 and 606, respectively. Pooled estimates showed that ICS administered once daily in the evening resulted in mild improvements in trough forced expiratory volume in 1 second (mean difference 0.05 L; 95% confidence interval 0.01-0.09; P = .026; I2 = 22.5%) and morning peak expiratory flow (mean difference 13.92 L/min; 95% confidence interval 5.77-22.06; P = .001; I2 = 13%) at end point compared with morning dosing. The change in use of rescue medicine and the incidence of adverse events with once-daily ICS were not significantly different between the 2 dosing times. CONCLUSION Compared with morning dosing, ICSs administered once daily in the evening seemed to provide some benefits in lung function for patients with asthma. However, because of methodologic limitations, further large-scale randomized clinical trials for dosing time of once-daily ICSs are needed.

Abstract
Although a minority of asthma patients suffer from severe asthma, they represent a major clinical challenge in terms of poor symptom control despite high-dose treatment, risk of exacerbations, and side effects. Novel biological treatments may benefit patients with severe asthma, but are expensive, and are only effective in appropriately targeted patients. In some patients, symptoms are driven by other factors than asthma, and all patients with suspected severe asthma ('difficult asthma') should undergo systematic assessment, in order to differentiate between true severe asthma, and 'difficult-to-treat' patients, in whom poor control is related to factors such as poor adherence or co-morbidities. The Nordic Consensus Statement on severe asthma was developed by the Nordic Severe Asthma Network, consisting of members from Norway, Sweden, Finland, Denmark, Iceland and Estonia, including representatives from the respective national respiratory scientific societies with the aim to provide an overview and recommendations regarding the diagnosis, systematic assessment and management of severe asthma. Furthermore, the Consensus Statement proposes recommendations for the organization of severe asthma management in primary, secondary, and tertiary care.

Abstract
INTRODUCTION This study was aimed at evaluating whether once-daily regimens (od-r) show benefits in adherence when compared to twice-daily (td-r). METHODS Prospective, multicenter, 6-month follow-up study with two visits. The main objective was to compare adherence assessed by the electronic prescription refill rate (EPRR) and by the 10-item Test of Adherence to Inhalers (TAI) in patients with od-r and td-r. Suboptimal adherence was defined as TAI < 50 or EPRR ≤ 80%. The effect of suboptimal adherence on meaningful clinical outcomes and the concordance between EPRR and TAI were also examined. RESULTS One hundred and ninety-seven patients (47.3 ± 15.9 years, 65% women) were included and 180 completed the study. TAI score was <50 in 29.8% od-r patients and 46.9% in td-r (p = 0.01) and EPRR was ≤80% in 22.6% and 37.5% respectively (p = 0.02). The correlation between the two methods was moderate (rho = 0.548; p < 0.001). There were no significant differences in FEV1 (%), symptoms or exacerbations between patients with optimal and suboptimal adherence. During follow-up, five patients (6%) with o-dr and 17 patients (17.7%) with t-dr suffered an exacerbation (p = 0.013). At visit two, 13.1% of the patients with o-dr and 31.3% with t-dr had uncontrolled asthma (p = 0.003), although more patients with o-dr were receiving inhaled corticosteroids in the high-dose stratum (25.8% vs. 11.5%; p = 0.001). CONCLUSION Mean adherence rates were greater with od-r than with td-r, but we did not observe an effect on clinical outcomes.

Abstract
PURPOSE OF THE REVIEW The six-minute walk test (6MWT) is a submaximal exercise test for evaluating physical functional capacity. This review aims to report the research on the use of the 6MWT in chronic heart failure (CHF) that has been published in the past 5 years. RECENT FINDINGS The 6MWT distance does not accurately reflect peak VO2. Minimal clinically important difference in the 6MWT distance, and additional measurements, such as heart rate recovery, can assist in the interpretation of the 6MWT distance, so management decisions can be made. Incorporating mobile apps and information technology in measuring the 6MWT distance extends the usefulness of this simple walk test and improve remote monitoring of patients with CHF. The 6MWT is a useful tool in CHF programs. However, interpretation of the 6MWT distance must be with caution. With the advancement in technology, the 6MWT has the potential to facilitate the monitoring of people living in rural and remote areas.

Electronic cigarette vapor alters the lateral structure but not tensiometric properties of calf lung surfactant. Respir Res 2017; 18:193.

Abstract
Background Despite their growing popularity, the potential respiratory toxicity of electronic cigarettes (e-cigarettes) remains largely unknown. One potential aspect of e-cigarette toxicity is the effect of e-cigarette vapor on lung surfactant function. Lung surfactant is a mixture of lipids and proteins that lines the alveolar region. The surfactant layer reduces the surface tension of the alveolar fluid, thereby playing a crucial role in lung stability. Due to their small size, particulates in e-cigarette vapor can penetrate the deep lungs and come into contact with the lung surfactant. The current study sought to examine the potential adverse effects of e-cigarette vapor and conventional cigarette smoke on lung surfactant interfacial properties. Methods Infasurf®, a clinically used and commercially available calf lung surfactant extract, was used as lung surfactant model. Infasurf® films were spread on top of an aqueous subphase in a Langmuir trough with smoke particulates from conventional cigarettes or vapor from different flavors of e-cigarettes dispersed in the subphase. Surfactant interfacial properties were measured in real-time upon surface compression while surfactant lateral structure after exposure to smoke or vapor was examined using atomic force microscopy (AFM). Results E-cigarette vapor regardless of the dose and flavoring of the e-liquid did not affect surfactant interfacial properties. In contrast, smoke from conventional cigarettes had a drastic, dose-dependent effect on Infasurf® interfacial properties reducing the maximum surface pressure from 65.1 ± 0.2 mN/m to 46.1 ± 1.3 mN/m at the highest dose. Cigarette smoke and e-cigarette vapor both altered surfactant microstructure resulting in an increase in the area of lipid multilayers. Studies with individual smoke components revealed that tar was the smoke component most disruptive to surfactant function. Conclusions While both e-cigarette vapor and conventional cigarette smoke affect surfactant lateral structure, only cigarette smoke disrupts surfactant interfacial properties. The surfactant inhibitory compound in conventional cigarettes is tar, which is a product of burning and is thus absent in e-cigarette vapor.

Modelling the effect of beliefs about asthma medication and treatment intrusiveness on adherence and preference for once-daily vs. twice-daily medication. NPJ Prim Care Respir Med 2017; 27:61.

Abstract
People with asthma who do not adhere to their maintenance medication may experience poorer asthma control and need more healthcare support than those who adhere. People (N = 1010) aged 18–55 years with self-reported asthma, taking one or more asthma maintenance medication(s), from five European countries, participated in a survey using validated scales (Medication Adherence Report Scale [MARS], Asthma Control Test™ [ACT], Beliefs about Medicine Questionnaire [BMQ] and the Asthma Treatment Intrusiveness Questionnaire [ATIQ]). We performed a post hoc evaluation of adherence to maintenance medication, asthma control, beliefs about medication, preferences for once-daily vs. twice-daily asthma maintenance medication and treatment intrusiveness, using structural equation modelling to investigate the relationships between these factors. Most participants reported potential problems with asthma control (ACT < 19: 76.8% [n = 776]), low adherence (median MARS = 3.40) and preferred once-daily medication (73.5% [n = 742/1010]). Non-adherence was associated with worse asthma control (r = 0.262 [P < 0.001]) and a expressed preference for once-daily medication over a "twice daily medication that works slightly better" (test statistic [T] = 2.970 [P = 0.003]). Participants reporting non-adherence/preferring once-daily medication had negative beliefs about their treatment (BMQ necessity-concerns differential: r = 0.437 [P < 0.001]/T = 6.886 [P < 0.001]) and found medication intrusive (ATIQ: r = −0.422 [P < 0.001]/T = 2.689[P = 0.007]). Structural equation modelling showed complex relationships between variables, including: (1) high concerns about treatment associated with increased perceived treatment intrusiveness and reduced adherence, which influenced asthma control; (2) high concerns about treatment and healthcare seeking behaviour, which were predictive of preferring twice-daily asthma medication. Concerns about medication and perceived treatment intrusiveness were predictive of poor adherence, and were associated with preference for once-daily asthma medication. Confirm the utility of the PAPA model and NCF in explaining nonadherence linked to poor asthma control. Encouraging adherence to maintenance medication for asthma requires a dual approach that considers patient perceptions as well as practicalities. While doctors may prescribe patients with appropriate medication to control asthma, many patients do not adhere to their maintenance regime. The reasons for this are complex, revolving around patient beliefs about long-term medication. Robert Horne at University College London, UK, and co-workers modelled data collected from interviews with 1010 adult patients from five European countries. Over a quarter of patients reported non-adherence and this was linked to concerns about ICS and perceived treatment intensiveness. Patients' beliefs about ICS and the concept of medication 'intrusiveness' were key factors in non-adherence. Understanding individual patient goals, eliciting patient concerns and addressing practical barriers should help encourage adherence.

Abstract
Inhaled therapies are the backbone of asthma and chronic obstructive pulmonary disease management, helping to target therapy at the airways. Adherence to prescribed treatment is necessary to ensure achievement of the clinician's desired therapeutic effect. In the case of inhaled therapies, this requires patients' acceptance of their need for inhaled therapy together with successful mastery of the inhaler technique specific to their device(s). This article reviews a number of challenges and barriers that inhaled mode of delivery can pose to optimum adherence-to therapy initiation and, thereafter, to successful implementation and persistence. The potential effects on adherence of different categories of devices, their use in multiplicity, and the mixing of device categories are discussed. Common inhaler errors identified by the international Implementing Helping Asthma in Real People (iHARP) study are summarized, and adherence intervention opportunities for health care professionals are offered. Better knowledge of common errors can help practicing clinicians identify their occurrence among patients and prompt remedial actions, such as tailored education, inhaler technique retraining, and/or shared decision making with patients regarding suitable alternatives. Optimizing existing therapy delivery, or switching to a suitable alternative, can help avoid unnecessary escalation of treatment and health care resources.

Abstract
INTRODUCTION A fixed-dose inhalation of a long-acting β-agonist (LABA) and inhaled corticosteroids (ICS) is commonly recommended for moderate to severe asthmatic patients not adequately controlled by an ICS only. In order to improve the patients' adherence and the control of disease there is a noteworthy interest for the next generation inhaled β adrenoreceptor agonists maintaining an over 24 hours bronchodilatation and used once-daily (ultra-LABAs). This review focuses on the currently available evidences on the clinical role of any single ultra-LABAs in the treatment of asthmatic patients. Areas covered: New ultra-LABAs have been developed in recent years for the treatment of asthma. In particular, several evidences in asthmatic patients include indacaterol, vilanterol, olodaterol, and abediterol. Expert opinion: Pharmacologically, all new ultra-LABAs considered have demonstrated a good ability to maintain a true bronchodilatation for over 24 hours and a good safety profile. This aspect could be a key point to improve the patient's perspective, the adherence to the treatment regimens and therefore the control of disease. At this time, however, limited data are available and no ultra-LABA+ICS may be recommended as preferred.

Abstract
INTRODUCTION The impact of asthma and chronic obstructive pulmonary disease (COPD) on individuals' lives may be substantial, yet clinical practice often focuses only on symptoms. We aimed to better understand the perspective of asthma or COPD patients and to identify condition-related burden, life impact, priorities, unmet needs, and treatment goals. METHODS Individuals aged at least 18 years with asthma or COPD were identified by a recruitment panel via clinical referrals, support groups, consumer networks, and a patient database. Interviews were carried out individually (by telephone) or in focus groups (with no more than five participants per group). A semi-structured interview guide was used with prespecified topics, informed by a literature review, that were considered impactful in asthma or COPD (symptoms and daily-life impact, satisfaction with current treatment, important aspects of treatment, adherence, and ideal treatment). RESULTS Overall, 72 people participated in focus groups/individual interviews (asthma n = 18/n = 21; COPD n = 15/n = 18). "Shortness of breath" was the most frequently reported symptom; however, participants discussed the life impact of their condition more than symptoms alone. Reported physical impacts included the inability to sleep and socialize, while emotional impacts included "embarrassment, stigma, and/or self-consciousness", "fear and/or panic", and "sadness, anxiety, and/or depression". Coping mechanisms for normal activities included continuing at reduced pace and avoidance. Treatment preferences centered on resolving impacts; improved sleep, "speed of action", and "length of relief" were the most frequently reported ideal treatment factors. CONCLUSION Patients with asthma or COPD experience substantial quality of life limitations and tend to focus on these in their expressions of concern, rather than symptoms per se. Life impacts of these conditions may have implications beyond those commonly appreciated in routine practice; these considerations will be applied to a future discrete choice experiment survey.

Abstract
BACKGROUND Despite its proven efficacy in improving symptoms and reducing exacerbations, many patients with asthma are not fully adherent to their steroid inhaler. Suboptimal adherence leads to poorer clinical outcomes and increased health service utilisation, and has been identified as a contributing factor to a third of asthma deaths in the UK. Reasons for non-adherence vary, and a variety of interventions have been proposed to help people improve treatment adherence. OBJECTIVES To assess the efficacy and safety of interventions intended to improve adherence to inhaled corticosteroids among people with asthma. SEARCH METHODS We identified trials from the Cochrane Airways Trials Register, which contains studies identified through multiple electronic searches and handsearches of other sources. We also searched trial registries and reference lists of primary studies. We conducted the most recent searches on 18 November 2016. SELECTION CRITERIA We included parallel and cluster randomised controlled trials of any duration conducted in any setting. We included studies reported as full-text articles, those published as abstracts only and unpublished data. We included trials of adults and children with asthma and a current prescription for an inhaled corticosteroid (ICS) (as monotherapy or in combination with a long-acting beta2-agonist (LABA)). Eligible trials compared an intervention primarily aimed at improving adherence to ICS versus usual care or an alternative intervention. DATA COLLECTION AND ANALYSIS Two review authors screened the searches, extracted study characteristics and outcome data from included studies and assessed risk of bias. Primary outcomes were adherence to ICS, exacerbations requiring at least oral corticosteroids and asthma control. We graded results and presented evidence in 'Summary of findings' tables for each comparison.We analysed dichotomous data as odds ratios, and continuous data as mean differences or standardised mean differences, all using a random-effects model. We described skewed data narratively. We made no a priori assumptions about how trials would be categorised but conducted meta-analyses only if treatments, participants and the underlying clinical question were similar enough for pooling to make sense. MAIN RESULTS We included 39 parallel randomised controlled trials (RCTs) involving adults and children with asthma, 28 of which (n = 16,303) contributed data to at least one meta-analysis. Follow-up ranged from two months to two years (median six months), and trials were conducted mainly in high-income countries. Most studies reported some measure of adherence to ICS and a variety of other outcomes such as quality of life and asthma control. Studies generally were at low or unclear risk of selection bias and at high risk of biases associated with blinding. We considered around half the studies to be at high risk for attrition bias and selective outcome reporting.We classified studies into four comparisons: adherence education versus control (20 studies); electronic trackers or reminders versus control (11 studies); simplified drug regimens versus usual drug regimens (four studies); and school-based directly observed therapy (three studies). Two studies are described separately.All pooled results for adherence education, electronic trackers or reminders and simplified regimens showed better adherence than controls. Analyses limited to studies using objective measures revealed that adherence education showed a benefit of 20 percentage points over control (95% confidence interval (CI) 7.52 to 32.74; five studies; low-quality evidence); electronic trackers or reminders led to better adherence of 19 percentage points (95% CI 14.47 to 25.26; six studies; moderate-quality evidence); and simplified regimens led to better adherence of 4 percentage points (95% CI 1.88 to 6.16; three studies; moderate-quality evidence). Our confidence in the evidence was reduced by risk of bias and inconsistency.Improvements in adherence were not consistently translated into observable benefit for clinical outcomes in our pooled analyses. None of the intervention types showed clear benefit for our primary clinical outcomes - exacerbations requiring an oral corticosteroid (OCS) (evidence of very low to low quality) and asthma control (evidence of low to moderate quality); nor for our secondary outcomes - unscheduled visits (evidence of very low to moderate quality) and quality of life (evidence of low to moderate quality). However, some individual studies reported observed benefits for OCS and use of healthcare services. Most school or work absence data were skewed and were difficult to interpret (evidence of low quality, when graded), and most studies did not specifically measure or report adverse events.Studies investigating the possible benefit of administering ICS at school did not measure adherence, exacerbations requiring OCS, asthma control or adverse events. One study showed fewer unscheduled visits, and another found no differences; data could not be combined. AUTHORS' CONCLUSIONS Pooled results suggest that a variety of interventions can improve adherence. The clinical relevance of this improvement, highlighted by uncertain and inconsistent impact on clinical outcomes such as quality of life and asthma control, is less clear. We have low to moderate confidence in these findings owing to concerns about risk of bias and inconsistency. Future studies would benefit from predefining an evidence-based 'cut-off' for acceptable adherence and using objective adherence measures and validated tools and questionnaires. When possible, covert monitoring and some form of blinding or active control may help disentangle effects of the intervention from effects of inclusion in an adherence trial.

Abstract
Muenke syndrome constitutes the most common syndromic form of craniosynostosis, occurring in 1 in 30,000 live births. The phenotype is variable, ranging from no clinical findings to complex presentation. Facilitating reproductive decision making for couples at genetic risk of having a child with Muenke syndrome is an important aspect of genetic counselling. Prenatal genetic testing for Muenke syndrome is accurate; however the value of testing is uncertain with a variable phenotype. The purpose of this study was to explore attitudes towards prenatal testing in couples where one partner had tested positive for the Muenke mutation. We used a qualitative approach based on thematic analysis and collected data using individual semi-structured interviews with eight parents. Five key themes were: The Muenke journey; Impact and knowledge of diagnosis; Knowledge and attitude to prenatal testing; Stigma and sharing of information; and Information retention. Knowledge of Muenke syndrome and prenatal testing was poor. Genetic information was provided when treatment of their affected child was their paramount concern. Couples reported not sharing genetic information with family due to fear of stigmatisation. Couples cannot make reproductive decisions if lacking appropriate understanding of the choices: timely genetic counselling regarding prenatal testing is needed when relevant to them.

Abstract
BACKGROUND Studies in adults and adolescents have demonstrated that tiotropium is efficacious as an add-on therapy to inhaled corticosteroids (ICSs) with or without other maintenance therapies in patients with moderate or severe symptomatic asthma. OBJECTIVE We sought to assess the efficacy and safety of once-daily tiotropium Respimat add-on therapy to high-dose ICS with 1 or more controller medications, or medium-dose ICS with 2 or more controller medications, in the first phase III trial of tiotropium in children with severe symptomatic asthma. METHODS In this 12-week, double-blind, placebo-controlled, parallel-group trial, 401 participants aged 6 to 11 years were randomized to receive once-daily tiotropium 5 μg (2 puffs of 2.5 μg) or 2.5 μg (2 puffs of 1.25 μg), or placebo (2 puffs), administered through the Respimat device as add-on to background therapy. RESULTS Compared with placebo, tiotropium 5 μg, but not 2.5 μg, add-on therapy improved the primary end point, peak FEV1 within 3 hours after dosing (5 μg, 139 mL [95% CI, 75-203; P < .001]; 2.5 μg, 35 mL [95% CI, -28 to 99; P = .27]), and the key secondary end point, trough FEV1 (5 μg, 87 mL [95% CI, 19-154; P = .01]; 2.5 μg, 18 mL [95% CI, -48 to 85; P = .59]). The safety and tolerability of tiotropium were comparable with those of placebo. CONCLUSIONS Once-daily tiotropium Respimat 5 μg improved lung function and was well tolerated as add-on therapy to ICS with other maintenance therapies in children with severe symptomatic asthma.

Abstract
INTRODUCTION Asthma is a prevalent disease affecting millions of individuals. Despite receiving guideline therapy with inhaled corticosteroids (ICS) with or without a long-acting β2-agonist (LABA), a proportion of patients remain symptomatic or have suboptimal lung function. There is therefore an unmet need for additional therapies to improve asthma control. The long-acting anticholinergic tiotropium, delivered via the Respimat inhaler, is approved for the treatment of asthma in the EU, the USA, and other countries. Phase III investigation in adults has demonstrated that tiotropium improves lung function and asthma control, with a safety profile comparable with that of placebo. Areas covered: Clinical trials in adolescent patients (aged 12-17 years) with moderate or severe symptomatic asthma have shown that tiotropium Respimat as add-on to ICS, with or without other maintenance therapies, is a well-tolerated and efficacious bronchodilator showing trends toward improved asthma control, similar to data in adult patients. Expert opinion: Tiotropium Respimat may be of benefit as add-on maintenance therapy to medium- or high-dose ICS with or without LABA; however, further data are needed to directly compare the efficacy of ICS plus tiotropium versus ICS plus LABA in adolescents with symptomatic asthma, and to establish the long-term effects on airway modeling.
