Abstract
INTRODUCTION Even though increased use of reliever medication, including short-acting beta agonists (SABA), provides an indirect measure of symptom worsening, there have been limited efforts to assess how different patterns of reliever use correlate with symptom control and future risk of exacerbations. Here, we evaluate the effect of individual baseline characteristics on reliever use in patients with moderate-severe asthma on regular maintenance therapy with fluticasone propionate (FP) or combination therapy with fluticasone propionate/salmeterol (FP/SAL) or budesonide/formoterol (BUD/FOR). METHODS A drug-disease model describing the number of 24-h puffs and overnight occasions was developed with data from five clinical studies (N = 6212). The model was implemented using a nonlinear mixed effects approach and a Poisson function, considering clinical and demographic baseline characteristics. Goodness of fit and model predictive performance were assessed. Heatmaps were created to summarise the effect of concurrent baseline factors on reliever utilisation. RESULTS The final model accurately described individual patterns of reliever use, which is significantly increased with time since diagnosis, smoking, higher Asthma Control Questionnaire (ACQ-5) score and higher body mass index (BMI) at baseline. Whilst the number of puffs decreases slowly after an initial drop relative to the start of treatment, exacerbating patients utilise significantly more reliever than those who do not exacerbate. The mean effect of FP/SAL (median dose: 250/50 μg BID) on reliever use was slightly higher than that of BUD/FOR (median dose: 160/4.5 μg BID), i.e. a 75.3% vs 69.3% reduction in reliever use, respectively. CONCLUSIONS The availability of individual-level patient data in conjunction with a parametric approach enabled the characterisation of interindividual differences in the patterns of reliever use in patients with moderate-severe asthma. Taken together, individual demographic and clinical characteristics, as well as exacerbation history, can be considered an indicator of the degree of asthma control. High SABA reliever use suggests suboptimal clinical management of patients on maintenance therapy.

JAMIA Open 2023; 6:ooad091. [PMID: 37900973 PMCID: PMC10602590 DOI: 10.1093/jamiaopen/ooad091] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Revised: 09/21/2023] [Accepted: 10/17/2023] [Indexed: 10/31/2023] Open
Abstract
Objective Changes in short-acting beta-agonist (SABA) use are an important signal of asthma control and risk of asthma exacerbations. Inhaler sensors passively capture SABA use and may provide longitudinal data to identify at-riskpatients. We evaluate the performance of several ML models in predicting daily SABA use for participants with asthma and determine relevant features for predictive accuracy. Methods Participants with self-reported asthma enrolled in a digital health platform (Propeller Health, WI), which included a smartphone application and inhaler sensors that collected the date and time of SABA use. Linear regression, random forests, and temporal convolutional networks (TCN) were applied to predict expected SABA puffs/person/day from SABA usage and environmental triggers. The models were compared with a simple baseline model using explained variance (R2), as well as using average precision (AP) and area under the receiving operator characteristic curve (ROC AUC) for predicting days with ≥1-10 puffs. Results Data included 1.2 million days of data from 13 202 participants. A TCN outperformed other models in predicting puff count (R2 = 0.562) and day-over-day change in puff count (R2 = 0.344). The TCN predicted days with ≥10 puffs with an ROC AUC score of 0.952 and an AP of 0.762 for predicting a day with ≥1 puffs. SABA use over the preceding 7 days had the highest feature importance, with a smaller but meaningful contribution from air pollutant features. Conclusion Predicted SABA use may serve as a valuable forward-looking signal to inform early clinical intervention and self-management. Further validation with known exacerbation events is needed.

Abstract
BACKGROUND We know that excessive short-acting β2-agonists (SABA) use in asthma may be associated to high exacerbation risks. We studied whether such excessive SABA consumption is connected with different higher oral corticosteroid (OC) prescriptions in the two sexes. METHODS In our prescribing database, we searched subjects aged 18-40 years that were prescribed at least one SABA package/year and/or at least two ICS or two ICS/LABA boxes/year to identify asthmatics. Their OC prescriptions/year were also examined. Subjects were divided into 4 groups according to SABA packages/year prescribed (0, 1-2,3-6 and ≥7), considering sexes separately. RESULTS Individuals recruited were 9,102. Subjects with at least one OC prescription were higher in each group and were females (P<0.001). The OC packages/year number was also more elevated in women especially those with >7 SABA prescriptions/year (0.96 in males vs. 2.64 in females, P<0.001). 94.7%/93.6% males/females, who never used SABA, took at least one ICS/LABA (mean 5.84/5.48 packages/year), while the subject percentage adhering to ICS/LABA dropped to 28-47% (mean 0.94-3.82 packages/year) in those who used SABA (P<0.001). Higher SABA prescriptions were associated with an increasing OC dispensation (β=0.057, P<0.0001). We observed also a greater risk of using >3 OC packages/year in subjects with 3-6 (OR: 2.98 [95% CI: 2.19-4.06], P<0.001) and ≥7 (OR: 3.49 [95% CI: 2.39-5.10], P<0.001) SABA prescriptions compared to those that never used SABA. Besides, we found that using ICS (OR:0.51 [95% CI: 0.35-0.75], P<0.001) or ICS/LABA (OR:0.07 [95% CI: 0.05-0.09], P<0.001) may significantly reduce SABA prescriptions. CONCLUSIONS Poor adherence to maintenance treatment appears to associated with excessive SABA prescriptions that may lead to a higher OC consumption particularly noticeable in women.

The Anti-Inflammatory Reliever (AIR) Algorithm Study: a protocol for a single-group study of an AIR stepwise approach to the treatment of adult asthma. ERJ Open Res 2023; 9:00239-2023. [PMID: 37753283 PMCID: PMC10518889 DOI: 10.1183/23120541.00239-2023] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Accepted: 07/03/2023] [Indexed: 09/28/2023] Open
Abstract
Background The stepwise approach to long-term asthma management, which traditionally incorporates short-acting β2-agonist reliever therapy, has been a core feature of asthma guidelines for over 30 years. There have been no studies, however, directly investigating the use of an entire guideline-recommended track. Recently, inhaled corticosteroid-formoterol has been recommended as the preferred reliever therapy in adult asthma, in accordance with a stepwise "Anti-Inflammatory Reliever" (AIR) treatment track. Objective The aim of this study was to evaluate the AIR stepwise approach recommended by the New Zealand adolescent and adult asthma guidelines, in combination with a novel algorithm for transitioning between treatment steps. Methods This 52-week, open-label, single-group study will recruit 100 adults aged 18 to 75 years with mild, moderate and moderate-severe asthma (ACTRN12620001010987). Participants will be allocated to budesonide-formoterol 200/6 µg, one actuation as needed (Step 1), one actuation twice daily and as needed (Step 2), or two actuations twice daily and one as needed (Step 3). Treatment steps will be adjusted throughout the study, in response to reliever use and asthma attacks, according to a stepwise AIR algorithm. Following a 26-week period of investigator-led transitions, participants will adjust their own treatment step. The primary outcome is participant satisfaction as measured by the Global Satisfaction score of the Treatment Satisfaction Questionnaire for Medication. Secondary outcomes will assess efficacy and safety, and describe patterns of medication use and participant flow through the treatment steps. Conclusion This is the first trial to assess the AIR treatment track and algorithm. The results will provide knowledge to guide the clinical use of this approach.

Abstract
Background Previous studies indicate that the percent recovery index (PRI: the percentage increase from the maximally reduced FEV1 after bronchodilator inhalation), one of the indexes of methacholine bronchial provocation, may predict acute asthma exacerbations in childhood and elderly asthmatics. It is known that childhood (<12) and elder (>60) asthmatics may be different to adult patients in many aspect including prognosis. However, in adults, a research for predicting value of PRI to exacerbation is still absence. Besides exacerbation, predicting value of PRI to poor asthma control is also unknown. We try to detect whether PRI can predict poor asthma control and exacerbation in adults in this research. Meanwhile, we try to detect whether treatment can influence PRI. Methods In 61 adults with asthma, baseline PRI was measured during enrollment. And then baseline PRI was evaluated as a predictor of exacerbation or poor asthma control at an upcoming 3-month follow-up. The covariates included age, sex, BMI, previous exacerbation, smoking status and baseline lung function. After treatment for 3 months, PRI was measured again and compared with baseline PRI. Results After the 3-month follow-up, we found that baseline PRI was significantly related to asthma exacerbation (P = 0.023), poor asthma control (ACT at 3 months, P = 0.014), decreased quality of life (decrease of MiniAQLQ, P = 0.010) and cumulative number of EDHO at 3 months (P = 0.039). Meanwhile, no significant correlation was observed between baseline PRI and inflammation factors (FENO, CaNO, and EOS). Finally, PRI was dramatically reduced after standard treatment for 3 months. Conclusion PRI is efficient in the prediction of poor asthma control and exacerbation in adults. The predictive value of PRI may rely on the inherent property of asthmatic airway smooth muscle (ASM) independent of inflammation factors. Effective treatment can alleviate PRI dramatically and that indicate PRI may also be valuable in evaluation of curative effect.

Abstract
PURPOSE Machine learning models informed by sensor data inputs have the potential to provide individualized predictions of asthma deterioration. This study aimed to determine if data from an integrated digital inhaler could be used to develop a machine learning model capable of predicting impending exacerbations. PATIENTS AND METHODS Adult patients with poorly controlled asthma were enrolled in a 12-week, open-label study using ProAir® Digihaler®, an electronic multi-dose dry powder inhaler (eMDPI) with integrated sensors, as reliever medication (albuterol, 90 µg/dose; 1-2 inhalations every 4 hours, as needed). Throughout the study, the eMDPI recorded inhaler use, peak inspiratory flow (PIF), inhalation volume, inhalation duration, and time to PIF. A model predictive of impending exacerbations was generated by applying machine learning techniques to data downloaded from the inhalers, together with clinical and demographic information. The generated model was evaluated by receiver operating characteristic area under curve (ROC AUC) analysis. RESULTS Of 360 patients included in the predictive analysis, 64 experienced a total of 78 exacerbations. Increased albuterol use preceded exacerbations; the mean number of inhalations in the 24-hours preceding an exacerbation was 7.3 (standard deviation 17.3). The machine learning model, using gradient-boosting trees with data from the eMDPI and baseline patient characteristics, predicted an impending exacerbation over the following 5 days with an ROC AUC of 0.83 (95% confidence interval: 0.77-0.90). The feature of the model with the highest weight was the mean number of daily inhalations during the 4 days prior to the day the prediction was made. CONCLUSION A machine learning model to predict impending asthma exacerbations using data from the eMDPI was successfully developed. This approach may support a shift from reactive care to proactive, preventative, and personalized management of chronic respiratory diseases.

Abstract
The risks of overusing short-acting β2-agonists (SABA), including an
increase in asthma-related deaths, are many and well known. The Global
Initiative on Asthma (GINA) 2019 and 2020 updates recommend as-needed inhaled
corticosteroid (ICS)/formoterol as the preferred rescue medication in mild
asthma as monotherapy and also in moderate to severe asthma when the maintenance
and reliever therapy (MART) strategy is used. Using SABA for symptom relief,
however, was the standard of treatment for many years, and consequently this
practice persists, particularly in patients not taking ICS regularly. Here, we
examine the rationale for this shift from a long-standing recommendation for
as-needed SABA treatment to the use of as-needed ICS/formoterol and consider
clinical evidence on strategies for asthma treatment and patient management.

Abstract
Use of digital communication technologies (DCT) shows promise for enhancing outcomes and efficiencies in asthma care management. However, little is known about the impact of DCT interventions on healthcare personnel requirements and costs, thus making it difficult for providers and health systems to understand the value of these interventions. This study evaluated the differences in healthcare personnel requirements and costs between usual asthma care (UC) and a DCT intervention (Breathewell) aimed at maintaining guidelines-based asthma care while reducing health care staffing requirements. We used data from a pragmatic, randomized controlled trial conducted in a large integrated health system involving 14,978 patients diagnosed with asthma. To evaluate differences in staffing requirements and cost between Breathewell and UC needed to deliver guideline-based care we used electronic health record (EHR) events, provider time tracking surveys, and invoicing. Differences in cost were reported at the patient and health system level. The Breathewell intervention significantly reduced personnel requirements with a larger percentage of participants requiring no personnel time (45% vs. 5%, p < .001) and smaller percentage of participants requiring follow-up outreach (44% vs. 68%, p < .001). Extrapolated to the total health system, cost for the Breathewell intervention was $16,278 less than usual care. The intervention became cost savings at a sample size of at least 957 patients diagnosed with asthma. At the population level, using DCT to compliment current asthma care practice presents an opportunity to reduce healthcare personnel requirements while maintaining population-based asthma control measures.

The Burden of Short-Acting β 2-Agonist Use in Asthma: Is There an Italian Case? An Update from SABINA Program. Adv Ther 2021; 38:3816-3830.

Abstract
Introduction Preliminary results from the SABINA (SABA use INAsthma) program showed lower overuse of short-acting β2-agonist (SABA) in Italy compared to other European countries. The aim of the present study was to ascertain whether SABINA’s results might have been affected by the Italian National Health System and pharmaceutical market dynamics, by examining patients’ characteristics in relation to SABA prescription/purchase habits. Methods Multiple approaches were used: (1) a retrospective study using the General Practitioners’ (GPs) Italian IQVIA Longitudinal Patient Database (LPD) to assess SABA overuse (more than two canisters/year) and its association with exacerbation risk; (2) a survey conducted across 200 Italian pharmacies to calculate the proportions of SABA purchases without a prescription; (3) a cross-sectional study on the specialists’ IQVIA Patient Analyzer database to understand the SABA prescription habits of specialists. Results Among SABA users identified through IQVIA LPD, the proportion of patients having more than two SABA canisters/year was 32%. Overall, patients prescribed more than two SABA canisters/year by GPs had 30% higher risk of exacerbations than patients with a maximum of two SABA canisters/year. The joint evaluation of IQVIA LPD and survey’s findings revealed that IQVIA LPD tracks three out of four SABA canisters dispensed. The survey showed that, on average, SABA users purchased four canisters/year. Patients prescribed SABA by specialists were more frequently men, younger, thinner, and had higher spirometry values. Conclusion SABA overuse is common in Italy, with a share of consumption not regulated by medical prescriptions. Because SABA overuse increases exacerbation risk, changes to national guidelines should be encouraged to ensure implementation of global recommendations.

Racine G, Forget A, Moullec G, Jiao T, Blais L, Lemiere C. Predictors of Asthma Control and Exacerbations: A Real-World Study. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY-IN PRACTICE 2021; 9:2802-2811.e2. [PMID: 33962067 DOI: 10.1016/j.jaip.2021.04.049] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 06/05/2020] [Revised: 04/12/2021] [Accepted: 04/19/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND Achieving optimal asthma control and minimizing the risk of exacerbation are the main goals of asthma treatment. OBJECTIVE This study aimed to assess the predictors of poor asthma control and asthma exacerbations within a population of moderate to severe asthmatic patients treated in a tertiary-care center. METHODS We conducted a cohort study assessing 738 patients enrolled in the Quebec registry in respiratory health (RESP) with a diagnosis of asthma confirmed by a respirologist and treated in a tertiary care center from April 2010 to March 2016. Sociodemographic and clinical data, including Asthma Control Questionnaire score, were collected at enrollment in the registry (ie, cohort entry) and patients were followed for a 2-year period thereafter. The information regarding exacerbations that occurred during follow-up was collected in administrative databases (Régie d l'assurance médicale du Québec [RAMQ], Maintenance et exploitation des données pour l'étude de la clientèle hospitalière [MED-ECHO], and medication data registry [reMed]). RESULTS We assessed 738 subjects (64% women). Psychological distress (odds ratio [OR] 1.91; 95% confidence interval [95% CI] 1.21-3.02), smoking (OR 3.72; 95% CI 1.72-8.05]), and poor lung function, forced expiratory volume in 1 second less than 50% (OR 4.1; 95% CI 1.48-11.34]) appeared as significant factors associated with uncontrolled asthma. Occurrence of previous asthma exacerbations (hazard ratio [HR] 6.25; 95% CI 4.01-9.75]), poor asthma control (HR 1.60; 95% CI 1.07-2.38]), forced expiratory volume in 1 second between 50% and 80% (HR 2.25; 95% CI 1.58-3.34]), and older age (HR 2.26; 95% CI 1.37-3.74]) were associated with asthma exacerbations. Adherence to asthma treatment was very low in patients with (44.4% ± 34.4%) and without asthma exacerbations (37.5% ± 33.0%). CONCLUSIONS Psychological distress and current smoking are modifiable factors that need to be addressed in tailored behavioral interventions to improve asthma control. Asthma exacerbations are mostly associated with the intrinsic severity of the disease.

Abstract
The use of remote monitoring and virtual visits has accelerated to support socially-distanced patient care during the COVID-19 pandemic. Despite the necessity of this expansion, ambiguity in coding is hindering adoption and patient access, most notably for remote physiologic monitoring due to a lack of definition of the term “physiologic”. In this analysis, we describe the history of remote monitoring code development, present several examples in respiratory disease and other chronic conditions in which gaps and confusion remain and suggest ways to clarify and broaden coverage to ensure equitable access to remote monitoring.

Abstract
Many asthma patients remain uncontrolled despite guideline-based therapies. We examined real-life asthma control in Japanese patients prescribed with inhaled corticosteroid/long-acting β2-agonist (ICS/LABA). Patients (≥12 years) with ≥2 asthma diagnoses, newly initiated on medium-/high-dose ICS/LABA (Japanese asthma guidelines), from 01 April 2009 to 31 March 2015 were included, using Japan Medical Data Center Claims Database. Primary objective: proportion of patients with uncontrolled asthma in the year following ICS/LABA initiation. Secondary objectives: predictors of uncontrolled asthma and healthcare resource utilization. In medium-dose (N = 24,937) and high-dose (N = 8661) ICS/LABA cohorts, 23% and 21% patients, respectively, were uncontrolled. Treatment step up and exacerbation were most common indicators of uncontrolled asthma. Predictors of uncontrolled asthma, analyzed by multivariable Cox model, included systemic corticosteroid use, exacerbation history, comorbidities, and being female. In both cohorts, healthcare resource utilization was higher in patients with uncontrolled asthma. Over 20% patients with persistent asthma who initiated medium- or high-dose ICS/LABA were uncontrolled, highlighting unmet need for novel therapies in these patients.

Abstract
BACKGROUND Multiple phenotypes exist within the classification of severe asthma. However, characteristics of patients with not well-controlled severe asthma have not been well identified. METHODS Japanese patients with asthma (age ≥ 20 years) were enrolled at the Keio University Hospital and its affiliated hospitals in this observational study (Keio Severe Asthma Research Program). Among them, patients with severe asthma (those undergoing Global Initiative for Asthma [GINA] 2018 step 4 or 5 treatment) were included in this analysis and investigated clinical characteristics based on asthma control status. RESULTS Of the 154 patients (men, 46.8%; age, 60.1 ± 14.9 years), 87 (56.5%) had not well-controlled (partly controlled and uncontrolled) asthma (GINA step 4, 42 patients; step 5, 45 patients). Overall, there were no significant differences in clinical characteristics between patients with well-controlled and not well-controlled asthma. However, cluster analysis revealed that distinct 5 clusters (cluster 1, well-controlled; cluster 2, eosinophilic; cluster 3, non-type 2 inflammation; cluster 4, high periostin; and cluster 5, late-onset type 2 inflammation), and clusters 2-5 were not well-controlled. Among them, cluster 3 was characterized by low eosinophil counts, low periostin levels, and less frequent olfactory disturbance, and this cluster had the worst asthma control. CONCLUSIONS Japanese patients with severe asthma were divided into well-controlled and not-well controlled asthma, and we confirmed heterogeneity of not well-controlled severe asthma. These patients, especially non-type 2 phenotype, require a further therapeutic approach. (University Hospital Medical Information Network Clinical Trials Registry, UMIN000002980).

Abstract
Asthma attacks (exacerbations) are common, accounting for over 90 000 UK hospital admissions per annum. They kill nearly 1500 people per year in the UK, have significant associated direct and indirect costs and lead to accelerated and permanent loss of lung function. The recognition of asthma as a heterogeneous condition with multiple phenotypes has revolutionised the approach to the long-term management of the condition, with greater emphasis on personalised treatment and the introduction of the treatable traits concept. In contrast asthma attacks are poorly defined and understood and our treatment approach consists of bronchodilators and systemic corticosteroids. This review aims to explore the current limitations in the description, assessment and management of asthma attacks. We will outline the risk factors for attacks, strategies to modify this risk and describe the recognised characteristics of attacks as a first step towards the development of an approach for phenotyping and personalising the treatment of these critically important events. By doing this, we hope to gradually improve asthma attack treatment and reduce the adverse effects associated with recurrent courses of corticosteroids.

Abstract
Although the “panic” word has been abundantly linked to the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) pandemic in the press, in the scientific literature very few studies have considered whether the current epidemic could predispose to the onset or the aggravation of panic attacks or panic disorder. Indeed, most studies thus far have focused on the risk of increase and aggravation of other psychiatric disorders as a consequence of the SARS-CoV-2 epidemic, such as obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), and generalized anxiety disorder (GAD). Yet, risk of onset or aggravation of panic disorder, especially the subtype with prominent respiratory symptoms, which is characterized by a fear response conditioning to interoceptive sensations (e.g., respiratory), and hypervigilance to these interoceptive signals, could be expected in the current situation. Indeed, respiratory symptoms, such as coughs and dyspnea, are among the most commonly associated with the SARS-CoV-2 (59–82% and 31–55%, respectively), and respiratory symptoms are associated with a poor illness prognosis. Hence, given that some etiological and maintenance factors associated with panic disorder – i.e., fear conditioning to abnormal breathing patterns attributable or not to the COVID-19 (coronavirus disease 2019), as well as hypervigilance towards breathing abnormalities – are supposedly more prevalent, one could expect an increased risk of panic disorder onset or aggravation following the COVID-19 pandemic in people who were affected by the virus, but also those who were not. In people with the comorbidity (i.e., panic disorder or panic attacks and the COVID-19), it is particularly important to be aware of the risk of hypokalemia in specific at-risk situations or prescriptions. For instance, in the case of salbutamol prescription, which might be overly used in patients with anxiety disorders and COVID-19, or in patients presenting with diarrhea and vomiting. Hypokalemia is associated with an increased risk of torsade de pointe; thus, caution is required when prescribing specific psychotropic drugs, such as the antidepressants citalopram and escitalopram, which are first-line treatments for panic disorder, but also hydroxyzine, aiming at anxiety relief. The results reviewed here highlight the importance of considering and further investigating the impact of the current pandemic on the diagnosis and treatment of panic disorder (alone or comorbid with the COVID-19).

Abstract
L’état de panique associé à la pandémie liée au SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) incite à s’interroger sur les troubles anxieux que cette situation pourrait générer ou aggraver. Si la littérature a déjà fourni des projections généralistes en la matière, les données concrètes concernent à ce stage davantage le trouble de stress post-traumatique et le trouble obsessionnel compulsif, tandis que quelques évaluations s’intéressent au cadre nosographie du trouble anxieux généralisé. Le trouble panique ne se voit que peu ou pas cité et l’évocation de la « panique », au sens social, la supplante largement. Bien que d’une légitimité clinique encore débattue, le trouble panique qualifié de « respiratoire » pourrait se voir augmenter en nombre et/ou être intensifié chez les patients qui en présentent déjà. D’éventuelles situations co-morbides entre un tel trouble et la COVID-19 (coronavirus disease 2019) doivent inciter à certaines précautions en matière de prescriptions médicamenteuses, notamment en lien avec les traitements ou situations, sources d’hypokaliémie : (i) le salbutamol, source potentielle de surconsommation, notamment chez les patients anxieux ; (ii) l’infection par le SARS-CoV-2 et plus encore en cas de diarrhées et/ou vomissements. L’hypokaliémie est associée à un risque accru de torsade de pointe, il convient donc également d’être prudent en matière de prescription de psychotropes à risque : comme avec le citalopram et l’escitalopram, des antidépresseurs indiqués dans le trouble panique ou encore l’hydroxyzine, à visée anxiolytique. Ces données sont de nature à resituer l’importance de la prise en considération du trouble panique dans le cadre de la pandémie en cours.

Abstract
Despite the availability of effective asthma treatments, some patients are poorly controlled because of overreliance on short-acting β2-agonists (SABAs) and underuse of inhaled corticosteroids (ICSs). To identify patient characteristics and outcomes associated with SABA overreliance and ICS underuse, we conducted a targeted literature review of the quantitative evidence on asthma medication use. Articles evaluating SABA and/or ICS use in patients with asthma (aged ≥12 years), published between January 2012 and March 2018, were identified using MEDLINE and EMBASE. We observed that studies classified SABA usage as "overuse," "high use," "excess use," "extreme overuse," "suboptimal use," and "inappropriate use." Multiple thresholds were used to define overuse of SABA (≥3 to ≥12 canisters/y). SABA overreliance was prevalent, with approximately 20% of adults using 3 or more canisters per year (≥12 inhalations/wk). Similarly, inappropriate ICS use, classified as "suboptimal," "high use," "underuse," and "unlicensed use," was defined by varying thresholds. Specific patient populations, such as older adults, smokers, and patients with low income, were more susceptible to SABA overreliance and ICS underuse. Overreliance on SABAs was associated with increased risk of severe exacerbations, asthma-related hospitalizations, emergency department visits, and asthma-related costs. These findings emphasize the prevalence and related burden of SABA overreliance at the potential expense of appropriate ICS use.

Abstract
The objective was to evaluate a multidisciplinary guideline-driven disease management program focused on achievement of asthma control among sustained patients with confirmed asthma in Louisiana and to assess factors affecting achievement of asthma control. Data were extracted from the electronic health records of 1596 adults with confirmed asthma, sustained care for >1 year in the outpatient setting, and ≥2 recorded Asthma Control Test (ACT) scores. Multivariable logistic regression modeling was used to assess the association of demographic variables, comorbidities, and process measures with the best achieved asthma control as represented by the highest ACT score. Most subjects were female (81.1%) and African American (63.9%). Approximately half of them (48.9%) were able to achieve asthma control (ACT ≥20). The most prevalent comorbidities were hypertension (79.8%), rhinitis (55.3%), and obesity (50.5%). Most patients received pulmonary function testing (PFT) (88.6%), controller medication therapy (85.5%), or written asthma action plans (92.7%). Asthma control was positively associated with presence of PFT (OR = 1.63, 95% CI: 1.13, 2.37) and being a "never" smoker (OR = 1.49, 95% CI: 1.08, 2.04). Asthma control was less likely to be achieved by patients who were African American (OR = 0.68, 95% CI: 0.52, 0.87), had more comorbidities (OR = 0.89, 95% CI: 0.83, 0.96), or were on more medications (OR = 0.79, 95% CI: 0.72, 0.88). Asthma control was achieved in 48.9% of an adult, primarily African American population with the implementation of comprehensive guideline-driven care. Furthermore, this is the first study to observe that the presence of PFT may be associated with asthma control.

Abstract
In a woman's life, asthma can affect her in a variety of ways, with the onset of premenstrual asthma currently under-diagnosed. It is estimated that about 20% of women with asthma have premenstrual asthma, which is more common in patients with severe asthma. Women with asthma are at high risk of exacerbations and of severe asthma. Asthma is the most common chronic disease during pregnancy with potential maternal and foetal complications. Asthma medications are safe for the foetus and it is essential to continue pre-existing treatment and adapt it to the progress of asthma during the pregnancy. Sex steroids modulate the structure and function of bronchial and immune cells. Understanding their role in asthma pathogenesis is complicated by the ambivalent effects of bronchodilating and pro-inflammatory oestrogens as well as the diversity of response to their association with progesterone. Menopausal asthma is a clinical entity and is part of one of the phenotypes of severe non-allergic and low steroid-sensitive asthma. Targeted assessment of the domestic and professional environment allows optimization of asthma management.

Abstract
Clinically, the treatments against asthma like β2 agonist focus on controlling the symptoms rather than inhibiting recurrence radically. This study aims to evaluate the efficacy and mechanism of a potent Chinese prescription Yu-Ping-Feng-San (YPFS) against asthma recurrence. We here established an optimized house dust mite (HDM)-induced asthma recurrence mice model with typical asthmatic responses such as significantly augmented airway hyperresponsiveness (AHR), elevated serum IgE, pulmonary type 2 cytokines IL-5 and IL-13 levels, pathological changes including thickening bronchial wall, inflammatory infiltration of lung tissue, etc. Moreover, all typical asthmatic pathological features were prominently alleviated by YPFS applied during remission phase ahead of second elicitation, which was even more effective than three different types of medications dexamethasone, montelukast and salbutamol, which were commonly applied in clinical practice, administered during recurrence phase. Besides, we found that desmoglein 1 (DSG1) remained deficient when asthmatic responses regressed whereas tight junction (TJ) claudin 1 (CLDN1) or adherin junction (AJ) E-cadherin restored spontaneously. In vitro, DSG1 interference resulted in increased thymic stromal lymphopoietin (TSLP) secretion, and epithelial barrier compromise evidenced by significantly elevated transepithelial electrical resistance (TEER) and increased 4-kDa FITC-dextran influx. YPFS could downregulate TSLP production and restore HDM-induced DSG1 deficiency and barrier destruction, which was further reversed by shDSG1. Collectively, administration of YPFS in remission prominently alleviated HDM-induced asthma relapse by restoring DSG1 and decreasing TSLP overexpression, which might be the key factors contributing to chronic asthma relapse. Our data not only demonstrated the pivotal role of DSG1 in asthma pathogenesis, but also provided a novel and potent therapeutic strategy against chronic asthma.

Abstract
BACKGROUND Tools for quantification of asthma severity are limited. OBJECTIVE We sought to develop a continuous measure of asthma severity, the Asthma Severity Scoring System (ASSESS), for adolescents and adults, incorporating domains of asthma control, lung function, medications, and exacerbations. METHODS Baseline and 36-month longitudinal data from participants in phase 3 of the Severe Asthma Research Program (NCT01606826) were used. Scale properties, responsiveness, and a minimally important difference were determined. External replication was performed in participants enrolled in the Severe Asthma Research Program phase 1/2. The utility of ASSESS for detecting treatment response was explored in participants undergoing corticosteroid responsiveness testing with intramuscular triamcinolone and participants receiving biologics. RESULTS ASSESS scores ranged from 0 to 20 (8.78 ± 3.9; greater scores reflect worse severity) and differed among 5 phenotypic groups. Measurement properties were acceptable. ASSESS was responsive to changes in quality of life with a minimally important difference of 2, with good specificity for outcomes of asthma improvement and worsening but poor sensitivity. Replication analyses yielded similar results, with a 2-point decrease (improvement) associated with improvements in quality of life. Participants with a 2-point or greater decrease (improvement) in ASSESS scores also had greater improvement in lung function and asthma control after triamcinolone, but these differences were limited to phenotypic clusters 3, 4, and 5. Participants treated with biologics also had a 2-point or greater decrease (improvement) in ASSESS scores overall. CONCLUSIONS The ASSESS tool is an objective measure that might be useful in epidemiologic and clinical research studies for quantification of treatment response in individual patients and phenotypic groups. However, validation studies are warranted.

Abstract
Asthma is a chronic inflammatory disorder of the airways. Disease presentation varies greatly in terms of cause, development, severity, and response to medication, and thus the condition has been subdivided into a number of asthma phenotypes. There is still an unmet need for the identification of phenotype-specific markers and accompanying molecular tools that facilitate the classification of asthma phenotype. To this end, we utilised a range of molecular tools to characterise a well-defined group of female adults with poorly controlled atopic asthma associated with house dust mite (HDM) allergy, relative to non-asthmatic control subjects. Circulating messenger RNA (mRNA) and microRNA (miRNA) were sequenced and quantified, and a differential expression analysis of the two RNA populations performed to determine how gene expression and regulation varied in the disease state. Further, a number of circulating proteins (IL-4, 5, 10, 13, 17 A, Eotaxin, GM-CSF, IFNy, MCP-1, TARC, TNFα, Total IgE, and Endotoxin) were quantified to determine whether the protein profiles differed significantly dependent on disease state. Finally, we utilised a previously published assessment of the circulating “blood microbiome” performed using 16S rRNA amplification and sequencing. Asthmatic subjects displayed a range of significant alterations to circulating gene expression and regulation, relative to healthy control subjects, that may influence systemic immune activity. Notably, several circulating mRNAs were detected in just the asthma group or just in the control group, and many more were observed to be expressed at significantly different levels in the asthma group compared to the control group. Proteomic analysis revealed increased levels of inflammatory proteins within the serum, and decreased levels of the bacterial endotoxin protein in the asthmatic state. Comparison of blood microbiome composition revealed a significant increase in the Firmicutes phylum with asthma that was associated with a concomitant reduction in the Proteobacteria phylum. This study provides a valuable insight into the systemic changes evident in the HDM-associated asthma, identifies a range of molecules that are present in the circulation in a condition-specific manner (with clear biomarker potential), and highlights a range of hypotheses for further study.

Abstract
Atopic bronchial asthma based on allergy history and chronic inflammation is hazardous to patients due to the risk of exacerbation. The sign of severe exacerbation is considered an abundant number and high activity of granulocytes in respiratory system and blood. Relationships between the ability of cells in blood to produce reactive radicals and their metabolites and the severity of asthma remain largely unclear. Kinetics of respiratory burst evoked by microbe particles in blood samples of patients was studied to reveal the most significant predictors distinguishing states of moderate exacerbation and out of exacerbation. Asthmatic patients with exacerbation (n = 18) or out of exacerbation (n = 62) and healthy individuals (n = 43) were characterized on respiratory function, cell count in blood and kinetics of generation of reactive radicals and their metabolites during phagocytosis. Mean values of respiratory parameters forced expiratory volume in 1 s and peak expiratory flow rate in patients with exacerbation were significantly differed compared with same of patients out of exacerbation and healthy individuals. Mean values of cell count in blood did not significantly differed in patients with exacerbation and out of exacerbation. Receiver operating characteristic analysis showed that both cell count and respiratory indexes did not discriminate patients with exacerbation from out of exacerbation. A delayed response to opsonized zymosan was revealed in patients with exacerbation compared to other examinees: lengthened lag-time and Tmax, reduced production of reactive species. Tmax was the most statistically significant predictor to discriminate bronchial asthma exacerbation from bronchial asthma out of exacerbation (area under curve >90%, p < 10-5) and controls (area under curve >80%, p < 10-5). Thus kinetic parameters of the phagocyte response to opsonized zymosan in the whole blood are the best predictors of bronchial asthma exacerbation in comparison with respiratory parameters and blood cell count. This test can be used for immunological monitoring of bronchial asthma status to prevent exacerbation.

Abstract
A major burden of severe asthma is the future risk of adverse health outcomes. Patients with severe asthma are prone to serious exacerbation and deterioration of lung function and may experience side effects of medications such as oral corticosteroids (OCSs). However, such future risk is not easily measurable in daily clinical practice. In particular, currently available tools to measure asthma control and asthma-related quality of life incompletely predict the future risk of medication-related morbidity. This is a significant issue in asthma management. This review summarizes the current evidence of future risk in patients with severe asthma. As future risk is poorly perceived by controlled asthmatics, our review focuses on the risk in patients with ‘controlled’ severe asthma. Of note, it is likely that long-term OCS therapy may not prevent future asthma progression, including lung function decline. In addition, the risk of drug side effects increases even during low-dose OCS therapy. Thus, novel treatments are highly desirable for reducing future risks without any loss of asthma control.

Abstract
Asthma is a common condition affecting 8.3% of the adult population in the United States. The disease is characterized by chronic airway inflammation that leads to airway hyperresponsiveness and obstruction that results in coughing, wheezing, shortness of breath, and a feeling of chest tightness. The diagnosis and classification of asthma is based on reported symptoms, physical examination findings, and spirometry. Pharmacologic therapy is prescribed using a stepwise approach that begins with inhaled short-acting beta2 -agonists for intermittent asthma with the addition of daily inhaled corticosteroids for more persistent cases. Individuals with asthma are reevaluated on a regular basis to monitor symptoms, and pharmacologic treatments are adjusted as needed. Familiarity with the stepwise approach for asthma management and confidence in the efficacy and safety profiles of inhaled medications will assist clinicians in successful management of asthma in the primary care setting.

Abstract
The general aim of this study is to create a cohort of asthma patients with varying grades of severity in order to gain greater insight into the mechanisms underlying the genesis and course of this disease. The specific objectives focus on various studies, including imaging, lung function, inflammation, and bronchial hyperresponsiveness, to determine the relevant events that characterize the asthma population, the long-term parameters that can determine changes in the severity of patients, and the treatments that influence disease progression. The study will also seek to identify the causes of exacerbations and how this affects the course of the disease. Patients will be contacted via the outpatient clinics of the 8 participating institutions under the auspices of the Spanish Respiratory Diseases Networking System (CIBER). In the inclusion visit, a standardized clinical history will be obtained, a clinical examination, including blood pressure, body mass index, complete respiratory function tests, and FENO will be performed, and the Asthma Control Test (ACT), Morisky-Green test, Asthma Quality of Life Questionnaire (Mini AQLQ), the Sino-Nasal Outcome Test 22 (SNOT-22), and the Hospital Anxiety and Depression scale (HADS) will be administered. A specific electronic database has been designed for data collection. Exhaled breath condensate, urine and blood samples will also be collected. Non-specific bronchial hyperresponsiveness testing with methacholine will be performed and an induced sputum sample will be collected at the beginning of the study and every 24 months. A skin prick test for airborne allergens and a chest CT will be performed at the beginning of the study and repeated every 5 years.

Abstract
OBJECTIVE Pulmonary rehabilitation (PR) is an important therapeutic approach in asthmatic patients. Lack of asthma control is associated with high morbidity, poor health outcomes, and decrease in quality of life (QOL). However, there is no clear information about the effectiveness of PR in patients with differing levels of asthma control. This study aimed to compare the efficacy of PR in patients with uncontrolled and partially controlled asthma. METHODS Before undergoing an 8-week outpatient PR program, patients were classified according to the asthma control test (ACT) as having partially controlled asthma or uncontrolled asthma. Changes in asthma control, exercise capacity, dyspnea perception, pulmonary function tests, arterial blood gas analysis, QOL, and psychological symptoms before and after PR were compared between groups. RESULTS A total of 49 patients, 21 of whom were in partially controlled and the rest 28 were in uncontrolled asthma, participated in the study. After PR, asthma control perceived dyspnea, exercise capacity, QOL, anxiety, and depression significantly improved in both groups (p < 0.05). When the two groups were compared in terms of the benefits of PR, the improvement in ACT score was significantly greater in patients with uncontrolled asthma than in partially controlled asthma (p < 0.001), whereas the improvements in other parameters were similar between groups (p > 0.05). CONCLUSIONS Improvement in asthma control is greater in patients with uncontrolled asthma than in patients with partially controlled asthma after PR. Therefore, patients with uncontrolled asthma, in particular, should be given opportunities to benefit from PR programs.

Abstract
BACKGROUND Asthma is often associated with other diseases. To identify and manage comorbidities is important, as these conditions may increase the disease burden. OBJECTIVE To describe the prevalence of comorbidities, disease burden and mortality across age groups in a large Swedish primary care real-life asthma population. METHODS Observational cohort study of asthma patients, all ages, identified from electronic medical records by ICD-10-CM code, data from 36 primary care centers. Data were linked to national mandatory Swedish health registers. Comorbidities were identified by ICD-10-CM codes and collected from electronic medical records and the National Patient Registers, mortality data from the Cause of Death Register. Exacerbations were defined as hospitalizations due to asthma, and/or emergency visits at hospital and/or prescription claims of oral steroids. RESULTS In total 33,468 patients (58% women) were included. The most prevalent comorbidities were acute upper respiratory tract infection (53%), rhinitis (25%), acute lower respiratory tract infection (25%), hypertension (21%), anxiety and depression (20%). The comorbidities associated with highest risk for an exacerbation were COPD OR 1.98 (95%CI: 1.80-2.19), nasal polyps OR 1.75 (95%CI: 1.49-2.05) and rhinitis OR 1.52 (95%CI: 1.41-1.63). All-cause mortality was similar to the Swedish population, 1011 deaths per 100,000 person/year compared with 1058 deaths (standardized risk = 0.99 [95%CI:0.95-1.04]). The pulmonary related death rate was greater in the study population versus the Swedish population (122 versus 72 per 100,000person/year). CONCLUSION Comorbid disease was frequent in this large real-life asthma population with an impact on exacerbations. To identify and treat comorbidities with impact on asthma outcomes are essential to improve asthma care.

Abstract
BACKGROUND A "frequent exacerbator phenotype" has been described, mostly in the population of patients with severe asthma. Further data are needed on such exacerbation-prone patients in milder asthma. AIM To compare the characteristics of frequent and nonfrequent exacerbators in asthma of different severities and to assess the stability of the exacerbator status. METHODS This was an observational study comparing baseline data from frequent (≥2 exacerbations in the past year) and nonfrequent (<2 exacerbations in the past year) exacerbators. Patients were also followed up for one year. Information regarding clinical, physiologic, and inflammatory characteristics was collected at baseline and one-year follow-up. RESULTS Forty-seven frequent and 53 nonfrequent exacerbators were recruited. No specific clinical, physiologic, or inflammatory characteristic was observed in the frequent as compared to the nonfrequent exacerbators at baseline. Fifty-eight percent of patients reporting frequent exacerbations at baseline remained in this group after one year of follow-up. Forty-two and 62% of patients with, respectively, mild-to-moderate asthma and severe asthma had frequent exacerbations. In a post hoc analysis according to asthma severity, frequent exacerbators with severe asthma had a higher body mass index and poorer asthma control, although they reported higher adherence to medication, in comparison to frequent exacerbators with mild-to-moderate asthma. No specific characteristics could discriminate between frequent and nonfrequent exacerbators of the same asthma severity. CONCLUSIONS Frequent exacerbators with severe asthma present some specific characteristics not observed in frequent exacerbators with mild-to-moderate disease. However, the latter group should be identified to reassess treatment needs and potential contributing factors.

Abstract
Background Healthcare systems are under increasing strain, predominantly due to chronic non-communicable diseases. Connected healthcare technologies are becoming ever more capable and their components cheaper. These innovations could facilitate both self-management and more efficient use of healthcare resources for common respiratory diseases such as asthma and chronic obstructive pulmonary disease. However, newer technologies can only facilitate major changes in practice, and cannot accomplish them in isolation. Focus of review There are now large numbers of devices and software offerings available. However, the potential of such technologies is not being realised due to limited engagement with the public, clinicians and providers, and a relative paucity of evidence describing elements of best practice in this complex and evolving environment. Indeed, there are clear examples of wasted resources and potential harm. We therefore call on interested parties to work collaboratively to begin to realize the potential benefits and reduce the risks of connected technologies through change in practice. We highlight key areas where such partnership can facilitate the effective and safe use of technology in chronic respiratory care: developing data standards and fostering inter-operability, making collaborative testing facilities available at scale for small to medium enterprises, developing and promoting new adaptive trial designs, developing robust health economic models, agreeing expedited approval pathways, and detailed planning of dissemination to use. Conclusion The increasing capability and availability of connected technologies in respiratory care offers great opportunities and significant risks. A co-ordinated collaborative approach is needed to realize these benefits at scale. Using newer technologies to revolutionize practice relies on widespread engagement and cannot be delivered by a minority of interested specialists. Failure to engage risks a costly and inefficient chapter in respiratory care.

THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY-IN PRACTICE 2017; 5:1663-1670.e5. [PMID: 28499773 DOI: 10.1016/j.jaip.2017.04.006] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 09/17/2016] [Revised: 03/29/2017] [Accepted: 04/04/2017] [Indexed: 01/11/2023]
Abstract
BACKGROUND Achieving and maintaining symptom control is a primary goal of asthma management. Although factors associated with the likelihood of achieving symptom control have been studied, there are unanswered questions on the stability of symptom control, that is, the tendency of individuals to remain at a given symptom control level over time. OBJECTIVE The objective of this study was to evaluate the stability of symptom control using a longitudinal cohort of mild-moderate asthmatics. METHODS Participants reported symptom control using the Global Initiative for Asthma criteria at 5 assessments during the 1-year follow-up period. We described variability in the stability of symptom control between individuals, and used a random-effects logistic regression model to evaluate the impact of a suite of factors on the stability of symptom control. RESULTS A total of 429 individuals (67% female, mean age 51.6) contributed 2141 study visits. Individuals varied from completely stable in symptom control (18% remained at the same control level in all 5 visits) to completely unstable (12% changed the control level between all subsequent visits). Only 4% of between-individual variation in the stability of symptom control was explained by the included exposures, and a secondary analysis indicated that the history of symptom control stability was the best predictor of current stability. CONCLUSIONS The tendency to remain at a given control level varies significantly among patients with asthma. Only a small fraction of this variability is explained by observable characteristics. In the absence of predictors, a previous history of symptom control stability is the best indicator of future stability and should be considered when monitoring symptom control.

Abstract
Asthma is one of the most common chronic diseases worldwide affecting more than 300 million people. Symptoms are often non-specific and include coughing, wheezing, chest tightness, and shortness of breath. Asthma may be highly variable within the same individual over time. Although asthma results in death only in extreme cases, the disease is associated with significant morbidity, reduced quality of life, increased absenteeism, and large costs for society. Asthma can be diagnosed based on report of characteristic symptoms and/or the use of several different diagnostic tests. However, there is currently no gold standard for making a diagnosis, and some degree of misclassification and inter-observer variation can be expected. This may lead to local and regional differences in the treatment, monitoring, and follow-up of the patients. The Danish National Database for Asthma (DNDA) is slated to be established with the overall aim of collecting data on all patients treated for asthma in Denmark and systematically monitoring the treatment quality and disease management in both primary and secondary care facilities across the country. The DNDA links information from population-based disease registers in Denmark, including the National Patient Register, the National Prescription Registry, and the National Health Insurance Services register, and potentially includes all asthma patients in Denmark. The following quality indicators have been selected to monitor trends: first, conduction of annual asthma control visits, appropriate pharmacological treatment, measurement of lung function, and asthma challenge testing; second, tools used for diagnosis in new cases; and third, annual assessment of smoking status, height, and weight measurements, and the proportion of patients with acute hospital treatment. The DNDA will be launched in 2016 and will initially include patients treated in secondary care facilities in Denmark. In the nearby future, the database aims to include asthma diagnosis codes and clinical data registered by general practitioners and specialised practitioners as well.

Age dictates a steroid-resistant cascade of Wnt5a, transglutaminase 2, and leukotrienes in inflamed airways. J Allergy Clin Immunol 2016; 139:1343-1354.e6.

Abstract
BACKGROUND Airway remodeling is a detrimental and refractory process showing age-dependent clinical manifestations that are mechanistically undefined. The leukotriene (LT) and wingless/integrase (Wnt) pathways have been implicated in remodeling, but age-specific expression profiles and common regulators remained elusive. OBJECTIVE We sought to study the activation of the LT and Wnt pathways during early- or late-onset allergic airway inflammation and to address regulatory mechanisms and clinical relevance in normal human bronchial epithelial cells (NHBEs) and nasal polyp tissues. METHODS Mice were sensitized with house dust mite (HDM) allergens from days 3, 15, or 60 after birth. Remodeling factors in murine bronchoalveolar lavage fluid, lung tissue, or human nasal polyp tissue were analyzed by means of Western blotting, immunoassays, or histology. Regulatory mechanisms were studied in cytokine/HDM-stimulated NHBEs and macrophages. RESULTS Bronchoalveolar lavage fluid LT levels were increased in neonatal and adult but reduced in juvenile HDM-sensitized mice. Lungs of neonatally sensitized mice showed increased 5-lipoxygenase levels, whereas adult mice expressed more group 10 secretory phospholipase A2, Wnt5a, and transglutaminase 2 (Tgm2). Older mice showed colocalization of Wnt5a and LT enzymes in the epithelium, a pattern also observed in human nasal polyps. IL-4 promoted epithelial Wnt5a secretion, which upregulated macrophage Tgm2 expression, and Tgm2 inhibition in turn reduced LT release. Tgm2, group 10 secretory phospholipase A2, and LT enzymes in NHBEs and nasal polyps were refractory to corticosteroids. CONCLUSION Our findings reveal age differences in LT and Wnt pathways during airway inflammation and identify a steroid-resistant cascade of Wnt5a, Tgm2, and LTs, which might represent a therapeutic target for airway inflammation and remodeling.

Abstract
Asthma affects about 300 million people globally and accounts for 1 in every 250 deaths in the world. Approximately 12 million people in the United States each year experience an acute exacerbation of their asthma, a quarter of which require hospitalization. Acute asthma should be differentiated from poor asthma control. Patients with acute asthma will exhibit increasing shortness of breath, chest tightness, coughing, and/or wheezing. In contrast, poor asthma control typically presents with a diurnal variability in airflow and is a characteristic that is usually not seen during an acute exacerbation. The history should include a review of comorbidities, adherence to medications, previous episodes of near-fatal asthma, and whether the patient has experienced multiple emergency department visits or hospitalizations, particularly those requiring admission to an intensive care unit involving respiratory failure, intubation, and mechanical ventilation. Patient education is important to ensure that the patient understands that asthma is mostly a chronic disease and necessitates the avoidance of allergens, prevention of infections, adherence with routine vaccinations, management of comorbid conditions, and adherence to treatment regimens. This article is a structured review of the available literature regarding the diagnosis and management of acute asthma.

Abstract
BACKGROUND Overuse of short-acting beta-agonists (SABA) is described in asthma, but little is known about overuse of SABA in chronic obstructive pulmonary disease (COPD). METHODS Prospective 3-month cohort study of patients with moderate-to-severe COPD who were provided a portable electronic inhaler sensor to monitor daily SABA use. Subjects wore a pedometer for 3 seven-day periods and were asked to complete a daily diary of symptoms and inhaler use. Overuse was defined as >8 actuations of their SABA per day while clinically stable. RESULTS Among 32 participants, 15 overused their SABA inhaler at least once (mean 8.6 ± 5.0 puffs/day), and 6 overused their inhaler more than 50% of monitored days. Compared to those with no overuse, overusers had greater dyspnea (modified Medical Research Council Dyspnea Scale: 2.7 vs. 1.9, p = 0.02), were more likely to use home oxygen (67% vs. 29%, p = 0.04), and were more likely to be on maximal inhaled therapy (long-acting beta-agonist, long-acting antimuscarinic agent, and an inhaled steroid: 40% vs. 6%, p = 0.03), and most had completed pulmonary rehabilitation (67% vs. 0%, p < 0.001). However, 27% of overusers of SABA were not on guideline-concordant COPD therapy. CONCLUSIONS Overuse of SABA was common and associated with increased disease severity and symptoms, even though overusers were on more COPD-related inhalers and more had completed pulmonary rehabilitation. More research is needed to understand factors associated with inhaler overuse and how to improve correct inhaler use.

Abstract
Background The SmartTouch Ventolin monitor (Adherium, Auckland, New Zealand) is an electronic monitor for use with a Ventolin metered dose inhaler, which records the date and time of inhaler actuations. This technology has the potential to allow in-depth analysis of patterns of inhaler use in clinical trial settings. The aim of this study was to determine the accuracy of the SmartTouch Ventolin monitor in recording Ventolin actuations. Methods 20 SmartTouch Ventolin monitors were attached to Ventolin metered dose inhalers. Bench testing was performed over a 10-week period, to reflect the potential time frame between visits in a clinical trial. Inhaler actuations were recorded in a paper diary, which was compared with data uploaded from the monitors. Results 2560 actuations were performed during the 10-week study period. Monitor sensitivity for diary-recorded actuations was 99.9% with a lower 97.5% confidence bound of 99.7%. The positive predictive value for diary-recorded actuations was 100% with a 97.5% lower confidence bound of 99.9%. Conclusions The SmartTouch Ventolin monitor is highly accurate in recording and retaining electronic data. It can be recommended for use in clinical trial settings in which training and quality control systems are incorporated into study protocols to ensure accurate data acquisition.

The wave of digital health is continuously growing and promises to transform healthcare and optimize the patients' experience. Asthma is in the center of these digital developments, as it is a chronic disease that requires the continuous attention of both health care professionals and patients themselves. The accurate and timely assessment of the state of asthma is the fundamental basis of digital health approaches and is also the most significant factor toward the preventive and efficient management of the disease. Furthermore, the necessity of inhaled medication offers a basic platform upon which modern technologies can be integrated, namely the inhaler device itself. Inhaler-based monitoring devices were introduced in the beginning of the 1980s and have been evolving but mainly for the assessment of medication adherence. As technology progresses and novel sensing components are becoming available, the enhancement of inhalers with a wider range of monitoring capabilities holds the promise to further support and optimize asthma self-management. The current article aims to take a step for the mapping of this territory and start the discussion among healthcare professionals and engineers for the identification and the development of technologies that can offer personalized asthma self-management with clinical significance. In this direction, a technical review of inhaler based monitoring devices is presented, together with an overview of their use in clinical research. The aggregated results are then summarized and discussed for the identification of key drivers that can lead the future of inhalers.

BMJ Open Respir Res 2015; 2:e000097. [PMID: 26629345 PMCID: PMC4653861 DOI: 10.1136/bmjresp-2015-000097] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2015] [Revised: 09/17/2015] [Accepted: 09/18/2015] [Indexed: 01/07/2023] Open
Abstract
BACKGROUND Electronic monitoring of inhaled asthma therapy is suggested as the 'gold standard' for measuring patterns of medication use in clinical trials. The SmartTurbo (Adherium (NZ) Ltd, Auckland, New Zealand) is an electronic monitor for use with a turbuhaler device (AstraZeneca, UK). The aim of this study was to determine the accuracy of the SmartTurbo in recording Symbicort actuations over a 12-week period of use. METHODS Twenty SmartTurbo monitors were attached to the base of 20 Symbicort turbuhalers. Bench testing in a research facility was undertaken on days 0, 5, 6, 7, 8, 9, 14, 21, 28, 56 and 84. Patterns of 'low-use' (2 sets of 2 actuations on the same day) and 'high-use' (2 sets of 8 actuations on the same day) were performed. The date and time of actuations were recorded in a paper diary and compared with data uploaded from the SmartTurbo monitors. RESULTS 2800 actuations were performed. Monitor sensitivity was 99.9% with a lower 97.5% confidence bound of 99.6%. The positive predictive value was 99.9% with a 97.5% lower confidence bound of 99.7%. Accuracy was not affected by whether the pattern of inhaler use was low or high, or whether there was a delay in uploading the actuation data. CONCLUSIONS The SmartTurbo monitor is highly accurate in recording and retaining electronic data in this 12-week bench study. It can be recommended for use in clinical trial settings, in which quality control systems are incorporated into study protocols to ensure accurate data acquisition.

Abstract
Gender differences in asthma incidence, prevalence and severity have been reported worldwide. After puberty, asthma becomes more prevalent and severe in women, and is highest in women with early menarche or with multiple gestations, suggesting a role for sex hormones in asthma genesis. However, the impact of sex hormones on the pathophysiology of asthma is confounded by and difficult to differentiate from age, obesity, atopy, and other gender associated environmental exposures. There are also gender discrepancies in the perception of asthma symptoms. Understanding gender differences in asthma is important to provide effective education and personalized management plans for asthmatics across the lifecourse.

Abstract
Purpose Bronchial asthma (BA) is a chronic inflammatory disorder of the airways, featuring variable and often reversible airflow limitations. An accurate assessment of BA control is difficult in practice, especially in the elderly, requiring the assessment of several clinical and paraclinical parameters that are influenced not only by asthma, but also by comorbidities. The purpose of this study was to evaluate the predictors of uncontrolled BA in a group of elderly patients from western Romania. Patients and methods We retrospectively evaluated 126 elderly patients (aged $ 65 years), who were consecutively evaluated in the Pulmonology Department of Victor Babes Hospital, Timisoara, Romania, between March 2009 and July 2012. We collected demographic data, performed pulmonary function testing and an asthma control test (ACT), and evaluated the level of BA control based on the 2012 Global Initiative for Asthma guidelines. Statistical processing of the data was done using the Epi Info and STATA programs. Results In our study group, 36 (29%) patients were men and 90 (71%) were women; their mean age was 74.42±8.32 years (range: 65–85 years). A total of 14.28% of patients were smokers. About 30.15% of patients had an ACT score <19, 54.76% had an ACT score 20–24, and 15.09% had an ACT of 25. Moreover, 59.52% had normal spirometry results. Infectious exacerbations were found in 58.73% of patients. A history of allergies was demonstrated in 48.41% of patients, 34.12% had occupational exposure, and 82.53% of patients were treated with inhaled corticosteroids. Our results showed that 30.15% of patients had uncontrolled BA. We found six predictive factors for uncontrolled BA: infectious exacerbation, occupational exposure, mixed (obstructive and restrictive) ventilatory dysfunction, persistent airway obstruction on spirometry, duration of disease in months, and current smoking status. Infectious exacerbations, persistent airway obstructions, and occupational exposure were the most powerful predictors. Conclusion Elderly patients represent an important group that is at risk for developing uncontrolled BA. Predictors may identify those elderly patients with uncontrolled BA and facilitate early medical interventions.
