Lung deposition of extrafine inhaled corticosteroid (ICS)-containing fixed combinations drug in COPD patients using Functional Respiratory Imaging (F…

2018

Introduction: FRI is a novel computational fluid dynamics (CFD)-based technique using formulation profile and patients lung CT scan to simulate aerosol deposition. Aims and objectives: To evaluate lung deposition of pressurized metered dose inhaler (pMDI) extrafine beclometasone dipropionate/formoterol fumarate/glycopyrronium (BDP/FF/G Trimbow®) with pMDI extrafine BDP/FF (Foster®) pMDI and compared them with reference gamma scintigraphy data. Methods: FRI was used to assess, in silico, the deposition of pMDI combination products (BDP/FF/G and BDP/FF) in 20 moderate to severe COPD patients. FRI combined high-resolution lung CT scans of each patient with in silico computational flow simulati…

Exploring the relevance and extent of small airways dysfunction in asthma (ATLANTIS): baseline data from a prospective cohort study

2019

BACKGROUND: Small airways dysfunction (SAD) is well recognised in asthma, yet its role in the severity and control of asthma is unclear. This study aimed to assess which combination of biomarkers, physiological tests, and imaging markers best measure the presence and extent of SAD in patients with asthma.METHODS: In this baseline assessment of a multinational prospective cohort study (the Assessment of Small Airways Involvement in Asthma [ATLANTIS] study), we recruited participants with and without asthma (defined as Global Initiative for Asthma severity stages 1-5) from general practices, the databases of chest physicians, and advertisements at 29 centres across nine countries (Brazil, Chi…

2021

Background: Functional respiratory imaging (FRI) is a computational fluid dynamics-based technique using three-dimensional models of human lungs and formulation profiles to simulate aerosol deposition. Methods: FRI was used to evaluate lung deposition of extrafine beclomethasone dipropionate (BDP)/formoterol fumarate (FF)/glycopyrronium bromide (GB) and extrafine BDP/FF delivered through pressurized metered dose inhalers and to compare results with reference gamma scintigraphy data. FRI combined high-resolution computed tomography scans of 20 patients with moderate-to-severe chronic obstructive pulmonary disease (mean forced expiratory volume in 1 second 42% predicted) with in silico comput…

Routine Use of Budesonide/Formoterol Fixed Dose Combination in Elderly Asthmatic Patients: Practical Considerations

2017

Asthma has been demonstrated to be as common in the elderly as in younger age groups. Although no specific recommendations exist to manage the disease differently in older individuals, functional features and clinical presentations may be affected by age per se, and by age-related conditions, such as comorbidities and polypharmacy. In this review article, we aimed to explore the efficacy and safety in elderly asthmatic patients of one of the most currently used inhaled treatments for asthma, that is, the fixed-dose combination of budesonide/formoterol. We attempted to address some practical questions that are relevant to the daily practice of clinicians. We focused on the efficacy and real-…

Lung deposition of extrafine vs non-extrafine triple therapies in patients with COPD using Functional Respiratory Imaging (FRI)

2019

Introduction: FRI is a validated computational fluid dynamics (CFD)-based technique using aerosol delivery performance profile, patients’ high-resolution lung CT scans and patient-derived inhalation profiles to simulate aerosol lung deposition. Aims and Objectives: To evaluate lung deposition patterns of extrafine beclometasone dipropionate/formoterol fumarate/glycopyrronium [BDP/FF/G; TRIMBOW®] pressurized metered dose inhaler (pMDI) and non-extrafine fluticasone furoate/vilanterol/umeclidinium [FluF/VI/UMEC; TRELEGY® ELLIPTA®] dry powder inhaler (DPI) in patients with stable COPD and moderate to very severe airflow obstruction. Methods: Intrathoracic depositions of the inhaled corticoster…

Anti-muscarinic drugs as preventive treatment of exercise-induced bronchoconstriction (EIB) in children and adults.

2020

Regular physical activity is strongly recommended to prevent chronic respiratory diseases, including asthma. On the other hand, vigorous physical training may trigger airway symptoms and bronchoconstriction. The transient airway narrowing occurring because of exercise is named exercise-induced bronchoconstriction (EIB). Despite management according to guidelines, a significant proportion of patients experiences uncontrolled EIB, which thus represents a relevant unmet medical need. In particular, although prevention and treatment of EIB are effectively based on the use of beta-2 bronchodilator drugs, high heterogeneity in individual responses has been reported. Furthermore, even though beta-…
