RESUMO
Purpose: The TRITRIAL study assessed the effects of beclometasone dipropionate/formoterol fumarate/glycopyrronium (BDP/FF/G) fixed combination in patients with chronic obstructive pulmonary disease (COPD) in a real-world setting, focusing on patient's experience and perspective through the use of patients reported outcomes. Patients and Methods: TRITRIAL was a multicenter, prospective, observational study conducted on patients with moderate-severe COPD treated with BDP/FF/G fixed therapy for 12 months. The main objective was to evaluate the impact of BDP/FF/G on health status through the COPD Assessment Test (CAT) score. Additional assessments included adherence and satisfaction, measured by the TAI-10/12 questionnaire and a specifically designed eight-item questionnaire, quality of life through the EQ-5D-5L test, sleep quality through the COPD and Asthma Sleep Impact Scale (CASIS), as well as safety and disease-related outcomes. Results: Data from 655 patients were analyzed in the study. The mean total CAT score significantly improved (from 22.8 at baseline to 18.1 at 6 months and 16.5 at 12 months; p < 0.0001), as well as all the eight CAT sub-items, which decreased on average by 0.5-0.9 points during the study. Adherence and usability of the inhaler also improved during the study, with a decrease in poor compliance (from 30.1% to 18.3%) and an increase in good compliance (from 51.8% to 58.3%) according to the TAI score. Patients also benefited from significantly improved quality of life (EQ Index from 0.70 to 0.80; EQ-5D VAS score from 55.1 to 63.1) and sleep quality (CASIS score from 41.1 to 31.8). Finally, patients reported a significant reduction in exacerbation during the study. Conclusion: TRITRIAL showed that the BDP/FF/G fixed combination is effective and safe in patients with moderate-severe COPD and poorly controlled disease, improving patients' HRQoL, sleep quality, adherence and inhaler usability and reducing COPD symptoms and the risk of exacerbation in a real-life setting.

In this article, we discuss the importance of real-world data in the treatment of patients with asthma and specifically the role of maintenance and reliever therapy (MART) with beclometasone dipropionate (BDP)/formoterol fumarate dihydrate (FF) delivered through a dry-powder inhaler (DPI) that contains an extrafine formulation. We also present the design of the NEWTON study. This multinational, multicenter, prospective, observational study will evaluate the real-world use of extrafine BDP/FF via a DPI as maintenance therapy and MART in patients with moderate to severe asthma. The study's primary outcome will be the proportion of patients improving their asthma control. Digitally collected patient-reported outcomes, such as the 5-item Asthma Control Questionnaire, the EuroQol 5-dimension 5-level, and the Test of the Adherence to Inhalers, will be used to assess the patient's asthma control, quality of life, and treatment adherence. Moreover, a new patient-reported outcome, the "Speed of change in health feeling" questionnaire, will be validated in a subgroup of patients. Overall, the results of this study will provide a real-life assessment of patients who perceived clinical benefits in a large cohort of asthmatics in Europe treated as per current clinical practice.
RESUMO
BACKGROUND: The fixed triple combination Beclometasone dipropionate/Formoterol fumarate/Glycopyrronium (BDP/FF/G, Trimbow®), an extrafine formulation in a unique pressurized metered dose inhaler, is indicated for the maintenance treatment in adult patients with moderate to severe COPD, not adequately treated by ICS/LABA or LABA/LAMA. Besides the evidence from three randomized controlled trials, the impact of fixed triple therapy has not been extensively evaluated in a real-world population of COPD patients. TRITRIAL (TRIple Therapy in Real life: Impact on Adherence and HeaLth status) is a non-interventional study to assess the effect of BDP/FF/G in a real world setting in Italy. DESIGN: TRITRIAL is a 12-month, multicenter, cohort, prospective, longitudinal observational study. Two follow-up visits will be performed at 6 and 12 months, respectively. The study includes the collection of anamnestic clinical and functional data before the start of BDP/FF/G. The study is built for digital conduction, from signature of the informed consent on a dedicated web platform, to the collection of questionnaires and clinical data on the eCRF. POPULATION: A total of 800 patients with COPD ranging from Global Initiative for Obstructive Lung Disease (GOLD) stages 2 to 4, receiving therapy with BDP/FF/G according to the Summary of Product Characteristics and local clinical practice, will be recruited. All concomitant therapies will be permitted for the duration of the study. EVALUATIONS: The primary endpoint is the change of CAT score at 12 months versus baseline. Secondary endpoints are adherence, health-related quality of life, sleep quality, disease-related outcomes (lung function and COPD exacerbations), device usability, economic resources consumption, and safety. CONCLUSION: TRITRIAL study is expected to give relevant information about effectiveness of BDP/FF/G fixed triple therapy in a real-life setting of patients with COPD, where adherence, usability of inhalers and patient's preference of the device are crucial factors for the success of the therapy.

Environmental agents, including viral and bacterial infectious agents, are involved in the alteration of physicochemical and biological parameters in the nasal epithelium. Hyaluronan (HA) has an important role in the regulation of tissue healing properties. High molecular weight HA (HMW-HA) shows greater anti-inflammatory responses than medium molecular weight HA (MMW-HA) and low molecular weight HA (LMW-HA). We investigated the effect of HMW-HA, MMW-HA and LMW-HA on the regulation of physicochemical and biological parameters in an "in vitro" model that might mimic viral infections of the nasal epithelium. Human nasal epithelial cell line RPMI2650 was stimulated with double-stranded RNA (dsRNA) Poly(I:C) for 5 days in air-liquid-interface (ALI) culture (3D model of airway tissue). dsRNA Poly(I:C) treatment significantly decreased transepithelial electrical resistance (TEER) in the stratified nasal epithelium of RPMI2650 and increased pH values, rheological parameters (elastic G' and viscous G"), and Muc5AC and Muc5B production in the apical wash of ALI culture of RPMI2650 in comparison to untreated cells. RPMI2650 treated with dsRNA Poly(I:C) in the presence of HMW-HA showed lower pH values, Muc5AC and Muc5B production, and rheological parameters, as well as increased TEER values in ALI culture, compared to cells treated with Poly(I:C) alone or pretreated with LMW-HA and MMW-HA. Our 3D "in vitro" model of epithelium suggests that HMW-HA might be a coadjuvant in the pharmacological treatment of viral infections, allowing for the control of some physicochemical and biological properties affecting the epithelial barrier of the nose during infection.

RESUMO
AIMS: Beclomethasone/formoterol (BDP/FOR) has been reported to be more effective than its separate components in airway disease control and in airway inflammation improvement. However, BDP/FOR effects on cytokine-induced inflammation in structural cells have not been described and whether these effects occur in a cell- and mediator-dependent manner has not been fully elucidated. We sought to evaluate BDP and/or FOR effects on endothelial ICAM-1, E-selectin, IL-8 and on bronchial epithelial ICAM-1 and IL-8. Specific intracellular signaling pathways were also investigated. MATERIALS AND METHODS: Surface adhesion molecule expression and IL-8 release induced by TNF-alpha were measured by ELISA. Intracellular signaling pathways were investigated by a) EMSA and Western blot analysis to evaluate NF-κB DNA-binding and MAPK-p38 phosphorylation; b) PDTC/SB203580 as NF-κB/p38 inhibitors; c) forskolin/H-89 as PKA activator/inhibitor. KEY FINDINGS: BDP/FOR additively reduced endothelial E-selectin and IL-8 as well as bronchial epithelial ICAM-1 and IL-8. BDP/FOR and SB203580 showed the highest inhibitory effect on epithelial IL-8, whereas endothelial ICAM-1 was never affected by BDP/FOR and PDTC. TNF-alpha-induced NF-κB DNA-binding and MAPK-p38 phosphorylation were not influenced by BDP/FOR. Forskolin mimicked FOR effects; H-89 partially reversed the BDP/FOR inhibition in a mediator-dependent manner. SIGNIFICANCE: The BDP/FOR inhibition degree was related to the inflammatory mediator- and cell-type considered. FOR additively enhanced BDP effects by partially involving both dependent- and independent-PKA mechanisms. Our results might contribute to highlight the strong relationship between specific molecular pathways and different sensitivity to the corticosteroid/ß2-agonist effects and to clarify the molecular mechanisms underlying the BDP/FOR anti-inflammatory activity in vivo.

IL-17A is involved in the activation of oxidative stress and inflammation in nasal epithelial cells. Hyaluronan (HA) in its high molecular weight form (HMW-HA) shows anti-inflammatory responses in contrast to low and medium molecular weight HA (LMW-HA and MMW-HA). The aim of this study was to investigate the pro- or anti-inflammatory biologic function of HA at different molecular weight in an in vitro model of nasal inflammation IL-17A mediated. We evaluated the ERK1/2 and IκBα phosphorylation, NF-κB signal pathway activation, ROS production, IL-8 and NOX-4 protein, and mRNA levels, in nasal epithelial cells RPMI 2650 stimulated with recombinant human (rh) IL-17A. Furthermore, the cells were treated with HMW-HA, MMW-HA, LMW-HA, and U0126. Our results showed that rhIL-17A increased the ERK1/2, IκBα phosphorylation and NF-κB signal pathway activation, ROS production, IL-8 and NOX-4 proteins, and mRNA levels. The addiction of HMW-HA or U0126 showed a significant downregulatory effect on inflammation due to the rhIL-17A stimulation in nasal epithelial cells. IL-17A is able to generate oxidative stress and inflammation via the activation of ERK1/2/NF-κB pathway in nasal epithelial cells. The HMW-HA might represent a coadjuvant of the classic anti-inflammatory/antioxidative treatment of nasal epithelial cells during IL-17A nasal inflammation.

BACKGROUND: According to the Global Initiative of Asthma, the aim of asthma treatment is to gain and maintain control. In the INTERNATIONAL CROSS-SECTIONAL AND LONGITUDINAL ASSESSMENT ON ASTHMA CONTROL (LIAISON) study, we evaluated the level of asthma control and quality of life (QoL), as well as their determinants and impact in a population consulting specialist settings. METHODS: LIAISON is a prospective, multicentre, observational study with a cross-sectional and a 12-month longitudinal phase. Adults with an asthma diagnosis since at least 6 months, receiving the same asthma treatment in the 4 weeks before enrolment were included. Asthma control was assessed with the 6-item Asthma Control Questionnaire (ACQ) and QoL with the MiniAsthma Quality of Life Questionnaire (MiniAQLQ). RESULTS: Overall, 8111 asthmatic patients were enrolled in 12 European countries. Asthma control was suboptimal in 56.5 % of patients and it was associated with poorer asthma-related QoL, higher risk of exacerbations and greater consumption of healthcare resources. Variables associated with suboptimal control were age, gender, obesity, smoking and comorbidities. Major determinants of poor asthma control were seasonal worsening and persisting exposure to allergens/irritants/triggers, followed by treatment-related issues. CONCLUSIONS: The cross-sectional phase results confirm that suboptimal control is frequent and has a high individual and economic impact. TRIAL REGISTRATION: The clinicaltrials.gov identifier is NCT01567280 .

Interleukin-17A (IL-17A), cigarette smoke and oxidative/nitrosative stress are involved in inflammatory airway diseases, and the mechanisms behind these processes are still poorly understood. We investigated whether recombinant human IL-17A (rhIL-17A), in combination with cigarette smoke extracts (CSE), increases the levels of inducibile nitric oxide synthase (iNOS), reactive oxygen species, nitrotyrosine (NT) and the activation of signal transducer and activator of transcription 1 (STAT-1) in normal human bronchial epithelial cells (16HBE). The effect of beclomethasone dipropionate (BDP), formoterol and their combination was also evaluated. We demonstrated that rhIL-17A or CSE alone increases iNOS expression, reactive oxygen species and NT production and STAT-1 downstream signalling activation in terms of STAT-1ser727 and STAT-1tyr701 phosphorylation. The combination of both stimuli further increased iNOS, ROS, NT and STAT-1ser727 phosphorylation. The silencing of STAT-1 expression partially reduced the levels of iNOS, reactive oxygen species and NT generated by rhIL-17A and inhibited the effect of CSE alone in 16HBE cells. The treatment of the cells with the MEK1/2 inhibitor U0126 (1,4-diamino-2,3-dicyano-1,4-bis (o-aminophenylmercapto butadiene) abolished the expression of iNOS and STAT-1ser727 phosphorylation generated by rhIL-17A. 16HBE treated with BDP or formoterol alone partially suppressed the effect of IL-17A or CSE on ROS, NT, and STAT-1 activation. Furthermore the use of the drugs in combination showed an additive effect in 16HBE. Our findings demonstrate that IL-17A increases oxidative/nitrosative markers, likely via ERK1/2 downstream signalling and STAT-1 pathway activation in human bronchial epithelial cells. BDP and formoterol treatment reduces this effect showing an additive effect used in combination.

BACKGROUND: According to international guidelines, the goal of asthma management is to achieve and maintain control of the disease, which can be assessed using composite measures. Prospective studies are required to determine how these measures are associated with asthma outcomes and/or future risk. The 'InternationaL cross-sectIonAl and longItudinal assessment on aSthma cONtrol (LIAISON)' observational study has been designed to evaluate asthma control and its determinants, including components of asthma management. METHODS/DESIGN: The LIAISON study will be conducted in 12 European countries and comprises a cross-sectional phase and a 12-month prospective phase. Both phases will aim at assessing asthma control (six-item Asthma Control Questionnaire, ACQ), asthma-related quality of life (Mini Asthma Quality of Life Questionnaire, Mini-AQLQ), risk of non-adherence to treatment (four-item Morisky Medication Adherence Scale, MMAS-4), potential reasons for poor control, treatment strategies and associated healthcare costs.The cross-sectional phase will recruit > 8,000 adult patients diagnosed with asthma for at least 6 months and receiving the same asthma treatment in the 4 weeks before enrolment.The prospective phase will include all patients with uncontrolled/poorly controlled asthma at the initial visit to assess the proportion reaching control during follow-up and to examine predictors of future risk. Visits will take place after 3, 6 and 12 months. DISCUSSION: The LIAISON study will provide important information on the prevalence of asthma control and on the quality of life in a broad spectrum of real-life patient populations from different European countries and will also contribute to evaluate differences in management strategies and their impact on healthcare costs over 12 months of observation. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT01567280.

OBJECTIVES: The study aimed at prospectively evaluating the evolution of asthma control in Italy, to evaluate the reasons for lack of asthma control, perceived quality of life (QoL) and association with level of asthma control, the impact of pharmacological treatment, the number of exacerbations and the healthcare resource consumption. METHODS: PRISMA (PRospectIve Study on asthMA control) was an observational study performed in asthmatic patients including a cross-sectional phase and a 12-month prospective phase. Asthma control was assessed with the Asthma Control Test™ (ACT) and QoL was evaluated with EuroQoL-5D questionnaire filled in and collected during 5 clinic visits together with all the other data. RESULTS: The prospective phase included 1017 patients with uncontrolled (55.7%) or partly controlled asthma (44.3%). Out of the 739 patients evaluable after 12 months, 22.2% achieved full asthma control (ACT score = 25) and 58.7% reached a good control (ACT score: 20-24). The improvement in asthma control was associated with improved QoL and reduced hospital visits. The main reasons for lack of asthma control were comorbidities, continued exposure to irritants/triggers and poor adherence to therapy. The frequency of exacerbations was lower in patients with controlled asthma.A fixed combination therapy with an inhaled corticosteroid and a long-acting ß2 agonist was reported by 77.0% of patients. A better asthma control and improved QoL were achieved with extrafine beclomethasone/formoterol compared to either budesonide/formoterol or fluticasone/salmeterol. CONCLUSIONS: An improvement in asthma control and QoL can be achieved during a 1-year monitoring in a real life setting. Extrafine beclomethasone/formoterol was associated with significant benefit in terms of asthma control and QoL compared to large-particles combinations.ClinicalTrials.gov number NCT01110460.

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