Single inhaler combination inhaled corticosteroid–formoterol as both maintenance and reliever (SMART) compared with a step up of treatment with fixed-dose inhaled corticosteroid–long-acting β2-agonist maintenance with a short-acting β2-agonist as reliever in adolescents and adults with poorly controlled asthma in Colombia: a cost-utility analysis

Objective The aim of the present study was to determine the cost-utility of single inhaler combination inhaled corticosteroid and a long-acting β2-agonist (ICS/LABAs) as both maintenance and reliever (SMART) compared with a step-up maintenance treatment with a fixed medium to high dose of ICS combined with LABA and a short-acting β2-agonist (SABA) as reliever (ICS-LABA maintenance plus SABA) among patients aged 12 years or more with poorly controlled asthma in Colombia. Methods A Markov-type model was developed to estimate the costs and health outcomes of a simulated cohort of patients aged 12 years or more with uncontrolled asthma treated for 12 months. The main effectiveness data were obtained from a recent meta-analysis. The main outcome was the variable ‘‘quality-adjusted life-years’’ (QALYs). Results The base-case analysis showed that the budesonide/formoterol (BUD/FORM) SMART strategy was associated with lower overall treatment costs (US $3,062.37 vs. $4,462.02 average cost per patient over 12 months) and the greatest gain in QALYs (0.8511 vs. 0.8258 QALYs on average per patient over 12 months) compared with ICS-LABA maintenance plus SABA at step 4, thus leading to dominance. Conclusions In patients aged 12 years or more with uncontrolled asthma at GINA step 3 or 4, the BUD/FORM SMART strategy at either step 3 or 4 is cost-effective compared with the ICS-LABA maintenance plus SABA at step 4 strategy, because it shows a greater gain in QALYs at lower total treatment costs.

A Simulation Study of the Effect of Clinical Characteristics and Treatment Choice on Reliever Medication Use, Symptom Control and Exacerbation Risk in Moderate-Severe Asthma.

The relationship between immediate symptom control, reliever medication use and exacerbation risk on treatment response and factors that modify it have not been assessed in an integrated manner. Here we apply simulation scenarios to evaluate the effect of individual baseline characteristics on treatment response in patients with moderate-severe asthma on regular maintenance dosing monotherapy with fluticasone propionate (FP) or combination therapy with fluticasone propionate/salmeterol (FP/SAL) or budesonide/formoterol (BUD/FOR). Reduction in reliever medication use (puffs/24h), change in symptom control scores (ACQ-5), and annualised exacerbation rate over 12months were simulated in a cohort of patients with different baseline characteristics (e.g. time since diagnosis, asthma control questionnaire (ACQ-5) symptom score, smoking status, body mass index (BMI) and sex) using drug-disease models derived from large phaseIII/IV clinical studies. Simulation scenarios show that being a smoker, having higher baseline ACQ-5 and BMI, and long asthma history is associated with increased reliever medication use (p < 0.01). This increase correlates with a higher exacerbation risk and higher ACQ-5 scores over the course of treatment, irrespective of the underlying maintenance therapy. Switching non-responders to ICS monotherapy to combination therapy after 3months resulted in immediate reduction in reliever medication use (i.e. 1.3 vs. 1.0 puffs/24h for FP/SAL and BUD/FOR, respectively). In addition, switching patients with ACQ-5 > 1.5 at baseline to FP/SAL resulted in 34% less exacerbations than those receiving regular dosing BUD/FOR (p < 0.01). We have identified baseline characteristics of patients with moderate to severe asthma that are associated with greater reliever medication use, poor symptom control and higher exacerbation risk. Moreover, the effects of different inhaled corticosteroid (ICS)/long-acting beta agonist (LABA) combinations vary significantly when considering long-term treatment performance. These factors should be considered in clinical practice as a basis for personalised management of patients with moderate-severe asthma symptoms.

Clinical value of Vitamin-D combined with budesonide/formoterol and theophylline sodium glycinate sustained-release tablets in the treatment of chronic obstructive pulmonary disease patients.

To explore the clinical value of Vitamin-D combined with budesonide/formoterol (BF) and theophylline sodium glycinate (TSG) sustained-release tablets in the treatment of patients with chronic obstructive pulmonary disease (COPD). Medical records of 114 patients with CODP, treated in Wenzhou Geriatric Hospital from October 2020 to February 2023, were retrospectively analyzed. Of them, 59 received treatment with Vitamin-D combined with BF and TSG sustained-release tablets (Group-A), and 55 patients received treatment with BF combined with TSG sustained-release tablets (Group-B). Lung function indicators, blood gas status, inflammatory factors, fractional exhaled nitric oxide (FeNO), and 25-hydroxyvitamin D [25(OH)D] levels before and after the treatment in both groups were collected. After the treatment, lung function indicators, blood gas status, inflammatory factors, FeNO, and 25 (OH) D levels in both groups were significantly improved compared to pretreatment levels, and were significantly better in the Group-A compared to Group-B (P<0.05). The combination of Vitamin-D, BF, and TSG sustained-release tablets can effectively regulate the blood gas status of patients with COPD, improve lung function, regulate FeNO and 25 (OH) D, and effectively downregulate the levels of inflammatory factors, thus reducing the degree of inflammatory response.

Comparative Efficacy of Budesonide/Formoterol Versus Fluticasone/Salmeterol in Patients With Moderate-to-Severe Chronic Obstructive Pulmonary Disease: A Systematic Review and Meta-Analysis

Background/objective To compare the efficacy of budesonide/formoterol (BF) versus fluticasone/salmeterol (FS) in patients with moderate-to-severe chronic obstructive pulmonary disease (COPD). Methods The PubMed, Embase, Cochrane Library, and Web of Science databases were searched for studies comparing BF versus FS in the treatment of COPD from inception to July 17, 2023. Outcomes, including exacerbations, hospitalizations, pneumonia, emergency department (ED) visits for COPD, length of hospitalization, and number of exacerbations, were compared using risk ratio (RR) with corresponding 95% confidence interval (CI) or weighted mean difference (WMD) with 95% CI. All statistical analyses were performed using Stata version 12.0. Results Ten studies comprising a total of 136,369 participants were included. Compared with those treated with FS, patients with COPD treated with BF experienced a reduced number of exacerbations (RR 0.91 [95% CI 0.83–1.00]; p = 0.040), hospitalizations (RR 0.77 [95% CI 0.67–0.88]; p < 0.001), and frequency of pneumonia (RR 0.77 [95% CI 0.64–0.92]; p = 0.05). However, no significant difference was observed between BF and FS in terms of ED visits for COPD (RR 0.87 [95% CI 0.69–1.10]; p = 0.243), length of hospitalization (WMD −0.18 [95% CI −0.62–0.27]; p = 0.437), and number of exacerbations (WMD −0.06 [95% CI −0.28–0.16]; p = 0.602). Notably, no significant heterogeneity was noted in length of hospitalization between the two groups, whereas clear heterogeneity was observed in other outcomes (I 2 > 50%, p < 0.05). Conclusion Compared with FS, BF therapy appears to be a more promising treatment strategy for patients with moderate-to-severe COPD; however, this should be verified in further high-quality studies.

Outcomes of Patients with COPD Treated with ICS/LABA Before and After Initiation of Single-Inhaler Triple Therapy with Fluticasone Furoate/Umeclidinium/Vilanterol (FF/UMEC/VI).

Triple therapy (fluticasone furoate/umeclidinium/vilanterol; FF/UMEC/VI) has been shown to improve symptoms and reduce exacerbations in patients with chronic obstructive pulmonary disease (COPD) and a history of exacerbations. This real-world study compared exacerbation rates and healthcare resource utilization (HCRU) before and after initiation of FF/UMEC/VI in patients with COPD previously treated with inhaled corticosteroid (ICS)/long-acting β2-agonist (LABA). This retrospective cohort study included commercial and Medicare Advantage with PartD administrative claims data from September01, 2016, to March31, 2020, of patients diagnosed with COPD. The index date was the date of the first FF/UMEC/VI claim (September 2017-March 2019). The 12months prior to index (baseline) were used to assess patient characteristics and outcomes; the 12months following index (follow-up) were used to assess study outcomes. All patients had ≥ 30 consecutive days' supply of any ICS/LABA dual therapy during the 12months prior to FF/UMEC/VI initiation. Subgroup analyses included patients with ≥ 30 consecutive days' supply of budesonide/formoterol (BUD/FORM) during baseline. Analyses of patients with ≥ 1 COPD exacerbation during baseline were reported as well. The overall population included 1449 patients (mean age 70.75years; 54.18% female), of whom 540 were patients in the BUD/FORM subgroup. Significantly fewer patients experienced any exacerbation during follow-up versus baseline (overall population 53.49% vs 62.59%; p < 0.001; BUD/FORM subgroup 55.00% vs 62.41%; p = 0.004). Effects on exacerbation reduction were more pronounced among patients with ≥ 1 exacerbation during baseline. Lower COPD-related HCRU was observed during the follow-up compared with baseline for both the overall population and the BUD/FORM subgroup. Patients with COPD treated with ICS/LABA during baseline, including patients specifically treated with BUD/FORM and those with a history of ≥ 1 exacerbation, had fewer COPD exacerbations and lower COPD-related HCRU after initiating FF/UMEC/VI.

Effect of Individual Patient Characteristics and Treatment Choices on Reliever Medication Use in Moderate-Severe Asthma: A Poisson Analysis of Randomised Clinical Trials.

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). 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. 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: 250/50μg BID) on reliever use was slightly higher than that of BUD/FOR (median dose: 160/4.5μg BID), i.e. a 75.3% vs 69.3% reduction in reliever use, respectively. 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.

Comparative effectiveness and safety of inhaled corticosteroid plus long-acting β2-agonist fixed-dose combinations vs. long-acting muscarinic antagonist in bronchiectasis

ABSTRACT Background This study aimed to evaluate the effectiveness and safety of fixed-dose combination (FDC) inhaled corticosteroids/long-acting β2-agonists (ICS/LABA) in bronchiectasis. Research design and methods A retrospective cohort study analyzed electronic medical records of bronchiectasis patients initiating ICS/LABA FDC or LAMA between 2007 and 2021. All bronchiectasis diagnoses were made by radiologists using high-resolution computed tomography. Results Of the 1,736 patients, 1,281 took ICS/LABA FDC and 455 LAMA. Among the 694 propensity score matched patients, ICS/LABA FDC had comparable outcomes to LAMA, with HRs of 1.22 (95% CI 0.81–1.83) for hospitalized respiratory infection, 1.06 (95% CI 0.84–1.33) for acute exacerbation, and 1.06 (95% CI 0.66–1.02) for all-cause hospitalization. Beclomethasone/formoterol (BEC/FOR) or budesonide/formoterol (BUD/FOR) led to a lower risk of acute exacerbation compared to fluticasone/salmeterol (FLU/SAL) (BEC/FOR HR 0.59, 95% CI 0.43–0.81; BUD/FOR HR 0.68, 95% CI 0.50–0.93). BEC/FOR resulted in lower risks of hospitalized respiratory infection (HR 0.48, 95% 0.26–0.86) and all-cause hospitalization (HR 0.55, 95% 0.37–0.80) compared to FLU/SAL. Conclusion Our findings provide important evidence on the effectiveness and safety of ICS/LABA FDC compared with LAMA for bronchiectasis. BEC/FOR and BUD/FOR were associated with better outcomes than FLU/SAL.

Clinical Efficacy Analysis of Tiotropium Bromide Combined with Budesonide and Formoterol Inhalation in Treating COPD

Objective: To analyze the clinical efficacy of tiotropium bromide (TB) combined with budesonide formoterol (BUD/FM) inhalation in treating chronic obstructive pulmonary disease (COPD). Methods: 62 COPD patients admitted to the hospital between June 2020 and December 2022 were selected as samples for this study. The patients were divided into a combination group and a conventional group using the random number table method, with 31 cases in each group. The patients in the combination group were treated with TB combined with BUD/FM inhalation, whereas the patients in the conventional group were treated with BUD/FM inhalation only. The treatment efficacy and changes in lung function indicators of both groups were compared. Results: The total efficacy of treatment in the combined group was higher than that in the conventional group, and the difference was statistically significant (P &lt; 0.05). Before treatment, there was no difference in pulmonary function indicators between the two groups (P &gt; 0.05). After three months of treatment, all lung function indicators of the combined group were higher than those of the conventional group, and the difference was statistically significant (P &lt; 0.05). Conclusion: Combining TB with BUD/FM inhalation therapy increases the efficacy of treatment for patients with COPD. Besides, it also improves lung function and leads to a better prognosis.

Application of Omalizumab Combined with Enteral Nutrition in Treating Severe Allergic Asthma

To investigate the influence of omalizumab combined with enteral nutrition in treating severe allergic asthma, 102 patients in our hospital from May 2020 to May 2023 were retrospectively included, followed by dividing into a control group and a study group. The control group received only budesonide formoterol, and the study group accepted budesonide formoterol, omazumab, and an oral enteral hypernutrient polymer. After therapy, the asthma control test score, mini-asthma quality of life questionnaire score, hemoglobin level, serum total protein level, serum total immunoglobulin E level, forced expiratory volume in one second, forced expiratory volume in one second predicted, CD3+, CD4+, and CD4+/CD8+ in the study group presented higher than the control group, while CD8+, fractional concentration of exhaled nitric oxide level, and percentage of eosinophils in blood were lower. No difference was observed in the incidence of adverse reactions between the two groups (P = 0.34). To sum up, enteral nutrition combined with omalizumab can effectively inhibit airway inflammation, improve lung function, and promote the quality of life of severe allergic asthma patients with high safety, which opens a new way of biologically targeting therapy for asthma.

Shenshu Dingchuan Decoction Enhances Clinical Benefits of Budesonide/Formoterol in Chronic Bronchial Asthma Patients

We have evaluated the clinical benefits of Shenshu Dingchuan decoction in chronic bronchial asthma patients treated with budesonide or formoterol. To this end, chronic bronchial asthma patients were divided into two groups and treated with budesonide or formoterol alone (the control group) or budesonide or formoterol plus Shenshu Dingchuan decoction (the treatment group). Shenshu Dingchuan decoction combined with budesonide formoterol decreased traditional Chinese medicine syndrome scores, elevated forced expiratory volume in one second, forced vital capacity, and forced expiratory volume in one second/forced vital capacity levels, decreased fractional exhaust nitric oxide and total immunoglobulin E levels, and the elevated total effective rate after treatment. In conclusion, these observed changes reflect a marked clinical improvement in lung function.

Efficacy of Jade Wind-Barrier Powder in adjuvant treatment for children with asthma, and its influence on IFN-γ, immunoglobulin and mucin

Purpose: To study the effects of Jade Wind-Barrier Powder on peripheral blood interferon-γ (INF-γ), immunoglobulin and sputum mucin in children with asthma.Methods: Sixty-six children with asthma in remission stage were randomly separated into study and control groups. The control group was treated with budesonide formoterol powder inhaler, while the study group was orally administered Jade Wind-Barrier Powder. The therapeutic effects, and INF-γ, immunoglobulin and mucin levels in sputum, as well as pulmonary function parameters in both groups were determined. The number of acute relapses of asthma and duration of wheezing were counted in the patients. The relative effectiveness of Jade Wind-Barrier Powder in the treatment of asthma in the children was also assessed.Results: The overall response rate (ORR) in the study group was 93.94 %, which was higher than in the control group (75.76 %, p &lt; 0.05). Over the 6-month period of follow-up, the frequency of acute attacks of asthma in the study group was significantly lower while the duration of wheezing during attack was also shorter than in the control group. After treatment, pulmonary function indices in the study group were higher, whereas mucin 5AC (MUC5AC), mucin 5B (MUC5B) and mucin 1 (MUC1) levels in sputum were lower than in the control group (p &lt; 0.05).Conclusion: Jade Wind-Barrier Powder exerts therapeutic effect in children with asthma. However, further clinical trials across multi-centers are required to validate it its use in clinical practice.

Understanding the Clinical Implications of Individual Patient Characteristics and Treatment Choice on the Risk of Exacerbation in Asthma Patients with Moderate-Severe Symptoms.

The assessment of future risk has become an important feature in the management of patients with asthma. However, the contribution of patient-specific characteristics and treatment choices to the risk of exacerbation is poorly understood. Here we evaluated the effect of interindividual baseline differences on the risk of exacerbation and treatment performance in patients receiving regular maintenance doses of inhaled corticosteroids (ICS) or ICS/long-acting beta-agonists (LABA) combination therapy. Exacerbations and changes to asthma symptoms 5-item Asthma Control Questionnaire (ACQ-5) were simulated over a 12-month period using a time-to-event and a longitudinal model developed from phaseIII/IV studies in patients with moderate-severe asthma (N = 16,282). Simulations were implemented to explore treatment performance across different scenarios, including randomised designs and real-world settings. Treatment options included regular dosing with ICS monotherapy [fluticasone propionate (FP)] and combination therapy [fluticasone propionate/salmeterol (FP/SAL) or budesonide/formoterol (BUD/FOR)]. Exacerbation rate was analysed using the log-rank test. The cumulative incidence of events was summarised stratified by treatment. Being a woman, smoker, having higher baseline ACQ-5 and body mass index (BMI) and lower forced expiratory volume in the first second (FEV1) are associated with increased exacerbation risk (p < 0.01). This risk is bigger in winter because of the seasonal variation effect. Across the different scenarios, the use of FP/SAL resulted in a 10% lower annual incidence of exacerbations relative to FP or regular dosing BUD/FOR, independently of baseline characteristics. Similar differences in the annual incidence of exacerbations were also observed between treatments in obese patients (BMI ≥ 25-35kg/m2) (p < 0.01) and in patients who do not achieve symptom control on FP monotherapy. Individual baseline characteristics and treatment choices affect future risk. Achieving comparable levels of symptom control whilst on treatment does not imply comparable risk reduction, as shown by the lower exacerbation rates in FP/SAL vs. BUD/FOR-treated patients. These factors should be considered as a basis for personalised clinical management of patients with moderate-severe asthma.

Effect of budesonide formoterol combined with tiotropium bromide on pulmonary function and inflammatory factors in patients with asthma-COPD overlap syndrome.

To investigate the clinical efficacy of combining budesonide formoterol with tiotropium bromide for treating asthma-chronic obstructive pulmonary disease overlap syndrome (AOCS). The data of 104 patients with AOCS admitted to our hospital from December 2019 to December 2020 were assessed, randomly and divided into an experimental group (comprising 52 patients, receiving drug combination therapy) and a conventional group (comprising 52 patients, receiving drug therapy alone). Patients' clinical efficacy, pulmonary function, fractioned exhaled nitric oxide (FeNO), immune function, endothelial function, serum lipid peroxidation injury indexes, adverse reactions, and quality of life scores were compared. Prior to treatment, no significant differences were observed in various pulmonary function indicators, FeNO, immune function, endothelial function, and lipid peroxidation injury indexes between the two groups (P > 0.05). However, after treatment, all observation indexes in both groups improved to different levels, with the experimental group -demonstrating -significantly superior improvement, compared to the conventional group (P < 0.05). We also observed that adverse reactions in the experimental group were significantly lower than in the conventional group (P < 0.05). The combination of budesonide formoterol to tiotropium bromide in treating asthma-COPD overlap syndrome may significantly improve pulmonary function, endothelial function, and immune status of patients and encourage the recovery of serum lipid peroxidation injury; therefore, this may deserve widespread adoption and application.

EE540 Budget Impact of Anti-Inflammatory Reliever Therapy with Budesonide-Formoterol Combination in the Treatment of Mild Asthma in Costa Rica

Asthma is a heterogeneous disease characterized by airway inflammation. Daily inhaled corticosteroid (ICS) plus short-acting beta-agonist (SABA) as a reliever is the standard of care (SoC) in Costa Rica for mild asthma. Anti-inflammatory reliever (AIR) therapy with budesonide–formoterol (Bud-Form) as needed is as effective as ICS monotherapy plus SABA as a reliever in reducing oral corticosteroid use, emergency room (ER) visits and hospitalizations; however, in Costa Rica, the information on the budget impact of the efficacy of AIR in patients with mild asthma is unknown.

EE73 Budget Impact of Anti-Inflammatory Reliever Therapy with Budesonide-Formoterol Combination in the Treatment of Mild Asthma in Honduras

Asthma is a heterogeneous disease characterized by airway inflammation. Daily inhaled corticosteroid (ICS) plus short-acting beta-agonist (SABA) as a reliever is the standard of care (SoC) in Honduras for mild asthma. Anti-inflammatory reliever (AIR) therapy with budesonide–formoterol (Bud-Form) as needed is at least as effective as ICS monotherapy plus SABA as a reliever in reducing oral corticosteroid use, emergency room (ER) visits and hospitalizations; however, in Honduras, the information on the budget impact of the efficacy of AIR in patients with mild asthma is unknown.

EE185 Budget Impact of Anti-Inflammatory Reliever Therapy with Budesonide-Formoterol Combination in the Treatment of Mild Asthma in Panama

Asthma is a heterogeneous disease characterized by airway inflammation. Daily inhaled corticosteroid (ICS) plus short-acting beta-agonist (SABA) as a reliever is the standard of care (SoC) in Panama for mild asthma. Anti-inflammatory reliever (AIR) therapy with budesonide–formoterol (Bud-Form) as needed is at least as effective as ICS monotherapy plus SABA as a reliever in reducing oral corticosteroid use, emergency room (ER) visits and hospitalizations; however, in Panama, the information on the budget impact of the efficacy of AIR in patients with mild asthma is unknown.

The match between adhesive mixture powder formulations for inhalation and the inhaler device

The device or the formulation? Which one governs drug dispersibility from the inhaler? To address this question, three budesonide-containing reservoir DPIs: Novopulmon Novolizer®, Giona Easyhaler® and DuoResp Spiromax®, were analyzed using the Next Generation Impactor, NGI. Thereafter, the devices were carefully opened, emptied, and formulations were switched between devices. Finally, three ‘prototype’ formulations with carriers of different particle size were produced and tested in the Novolizer and Easyhaler devices.Among the DPI products, the two devices which have a flow path with a cyclone-type geometry, i.e., the Novolizer and the Spiromax, yielded a fine particle fraction, FPF, above 40%. The Easyhaler, which has a straight mouthpiece outlet, produced an FPF of 18%. When the Novopulmon and the DuoResp formulations were assayed in the Easyhaler device, poor fine particle fractions were obtained. To the contrary, the Giona formulation produced a high FPF when tested in the Novolizer device. The results clearly show that the device is the dominating factor to dispersibility for the investigated products. Along the same lines, all three ‘prototype’ formulations produced high fine particle fractions in the Novolizer device, with the formulation with the largest carrier giving the best performance. Tested in the Easyhaler device, the prototype formulations produced low fine particle fractions, but interestingly, the formulation with the smallest carrier particle size yielded the highest FPF. It can be concluded that there is a link between inhaler design and the effect of carrier particle size, where larger carriers provide better dispersion in cyclone-type devices while smaller carriers seem to be more beneficial for inhalers which has a straight flow path for the powder formulation.

Effectiveness of budesonide formoterol fixed-dose combination MDI in reducing cough symptoms in COVID-19 patients: A real-world evidence study.

Cough is a wearisome and exasperating symptom affecting the daily life of the infected patient. Cough due to coronavirus disease 2019 (COVID-19) causes excessive morbidity in human populations globally. Apart from the morbidity associated with cough, it also enhances the transmission of this viral infection through droplets. Therefore, curbing cough is crucial to limit its spread. Patients often administer over-the-counter products and antitussive agents, which have no proven benefit. The present study was undertaken to find out if cough associated with COVID-19 and other indicative clinical outcomes is alleviated with a budesonide/formoterol fixed-dose combination (FDC) metered-dose inhaler (MDI). A prospective observational study was conducted in mild COVID-19 patients who presented with a cough score ≥8 at presentation. Patients who were initiated on ICS-LABA MDI were observed as group A and those who were not initiated on MDI were observed as Group B. Cough symptom score (at baseline and on day 3 and day 7), the incidence of hospital admission and/or death, and need for mechanical ventilation were documented. Prescribing patterns of anti-cough medications were also noted and analysed. Compared to group B, a higher mean cough score reduction was noted for group A patients at day 3 and day 7 when compared to the baseline, and this was significant at P < 0.001. A significant negative correlation was also observed between mean latency of MDI initiation from the symptom onset and mean cough score reduction. Analysis of the proportion of patients prescribed medications to treat cough showed that overall, 10.78% did not require these, with a greater proportion in group A compared to group B. Patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) COVID-19 who were treated with ICS-LABA MDI along with usual care benefitted significantly in terms of symptom reduction compared to usual care.

Digital Coaching Using Smart Inhaler Technology to Improve Asthma Management in Patients With Asthma in Italy: Community-Based Study.

Reliance on short-acting β-2 agonists and nonadherence to maintenance medication are associated with poor clinical outcomes in asthma. Digital health solutions could support optimal medication use and therefore disease control in patients with asthma; however, their use in community settings has not been determined. The primary objective of this study is to investigate community implementation of the Turbu+ program designed to support asthma self-management, including adherence to budesonide and formoterol (Symbicort) Turbuhaler, a combination inhaler for both maintenance therapy or maintenance and reliever therapy. The secondary objective is to provide health care professionals with insights into how patients were using their medication in real life. Patients with physician-diagnosed asthma were prescribed budesonide and formoterol as maintenance therapy, at a dose of either 1 inhalation twice daily (1-BID) or 2 inhalations twice daily (2-BID), or as maintenance and reliever therapy (1-BID and reliever or 2-BID and reliever in a single inhaler), and they received training on Turbu+ in secondary care centers across Italy. An electronic device attached to the patients' inhaler for ≥90 days (data cutoff) securely uploaded medication use data to a smartphone app and provided reminders, visualized medication use, and motivational nudge messages. Average medication adherence was defined as the proportion of daily maintenance inhalations taken as prescribed (number of recorded maintenance actuations per day or maintenance inhalations prescribed per day) averaged over the monitoring period. The proportion of adherent days was defined as the proportion of days when all prescribed maintenance inhalations were taken on a given day. The Wilcoxon test was used to compare the proportion of adherent days between patients in the maintenance regimen and patients in the maintenance and reliever regimen of a given dose. In 661 patients, the mean (SD) number of days monitored was 217.2 (SD 109.0) days. The average medication adherence (maintenance doses taken/doses prescribed) was 70.2% (108,040/153,820) overall and was similar across the groups (1-BID: 6332/9520, 66.5%; 1‑BID and reliever: 43,578/61,360, 71.0%; 2-BID: 10,088/14,960, 67.4%; 2-BID and reliever: 48,042/67,980, 70.7%). The proportion of adherent days (prescribed maintenance doses/doses taken in a given day) was 56.6% (31,812/56,175) overall and was higher with maintenance and reliever therapy (1-BID and reliever vs 1-BID: 18,413/30,680, 60.0% vs 2510/4760, 52.7%; P<.001; 2-BID and reliever vs 2-BID: 8995/16,995, 52.9% vs 1894/3740, 50.6%; P=.02). Rates of discontinuation from the Turbu+ program were significantly lower with maintenance and reliever therapy compared with maintenance therapy alone (P=.01). Overall, the high medication adherence observed during the study might be attributed to the electronic monitoring and feedback mechanism provided by the Turbu+ program.

Effect of Recent Exacerbation History on the Efficacy of Once-Daily Single-Inhaler Fluticasone Furoate/Umeclidinium/Vilanterol Triple Therapy in Patients with Chronic Obstructive Pulmonary Disease in the FULFIL Trial.

BackgroundIn the FULFIL trial, once-daily single-inhaler triple therapy with fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) resulted in reduced moderate/severe exacerbation rates and conferred significant improvements in lung function and health status in patients with chronic obstructive pulmonary disease (COPD) versus twice-daily budesonide/formoterol (BUD/FOR) dual therapy.MethodsFULFIL was a Phase III, randomized, double-blind, double-dummy, parallel-group study. Patients ≥40 years of age with symptomatic COPD were randomized 1:1 to FF/UMEC/VI 100/62.5/25 mcg or BUD/FOR 400/12 mcg. In this post hoc analysis, patients were categorized by exacerbation history in the year prior to study entry (≥1 moderate/severe exacerbation [recent exacerbation] versus no recent exacerbation). Endpoints included annual rate of on-treatment moderate/severe exacerbations up to Week 24, annual rate of on-treatment severe exacerbations up to Week 24, change from baseline in trough forced expiratory volume in 1 second at Week 24, and change from baseline in health status as measured by St George’s respiratory questionnaire total score at Week 24.ResultsOf the 1810 patients in the intent-to-treat population, 1180 (65%) had one or more moderate/severe exacerbation in the year prior to entry, while 630 (35%) patients did not. FF/UMEC/VI versus BUD/FOR significantly reduced moderate/severe exacerbation rates in the recent exacerbation subgroup (mean annualized rate: 0.19 vs 0.29; rate ratio [95% confidence interval [CI]]: 0.64: [0.45, 0.91]; p=0.014) and numerically reduced moderate/severe exacerbation rates in the no recent exacerbation subgroup (mean annualized rate: 0.29 vs 0.43; rate ratio [95% CI]: 0.67 [0.43, 1.04]; p=0.073). Severe exacerbation rates were numerically reduced with FF/UMEC/VI versus BUD/FOR treatment across both subgroups. FF/UMEC/VI conferred significant improvements in lung function and health status versus BUD/FOR, regardless of recent exacerbation history.ConclusionFF/UMEC/VI reduced moderate/severe and severe exacerbation rates and improved lung function and health status versus BUD/FOR in patients with symptomatic COPD, regardless of recent exacerbation history.
