Filter by:Salbutamol use is increased in areas with high levels of ozone pollution and the potential consequences of this are not well known. The purpose of this study is to examine the effect of salbutamol on lung function and inflammation in people with asthma and/or EIB exercising in ozone air pollution. To examine this, we are planning a randomized cross over trial where people with asthma and/or EIB complete sub maximal exercise in four conditions on four separate days. The four condition are: ozone + salbutamol, filtered air + salbutamol, ozone + placebo medication, and filtered air + placebo medication.
Bioequivalence study between two inhaler products of fixed dose combination of fluticasone propionate and salmeterol xinafoate inhalation powder
The study compares Buventol® Easyhaler® and Bufomix® Easyhaler® to the current standard treatment during methacholine challenge test. The trial will also provide inspiratory flow profile data for Easyhaler inhaler. This trial is designed to provide a further evidence for the use of Easyhaler in diagnostic bronchial challenge tests and on the use of Easyhaler inhaler during obstructive event.
Retrospective, multicenter, routine clinical practice study with consecutive inclusion of adult patients with severe eosinophilic asthma receiving benralizumab treatment.
The purpose of this study is to characterize and compare the molecular gene expression profile in endobronchial biopsies and cells recovered in bronchial washings from study subjects who have asthma of varying disease severity and who are on maintenance inhaled corticosteroid (ICS) treatment, with that for healthy control subjects. These studies will produce transcriptomic profiles of gene expression associated with asthma disease severity. The investigators will also culture epithelial cells from study participant endobronchial brushings, including those with asthma of varying disease severity and healthy control subjects, to examine differences in the response to corticosteroids (CS) in vitro. These studies will test whether intrinsic differences exist between the responses to ICS in each group. 60 participants will be recruited with 15 of each mild, moderate and severe asthma as defined by the Global Initiative for Asthma (GINA) guidelines, as well as 15 healthy controls. Participants will undergo an initial visit to obtain informed consent, bloodwork and to assess asthma control using the Asthma Control Questionnaire (ACQ); if >1.5, ICS dose will be increased, as per GINA strategy, for a 2 week 'stabilization' phase. Repeat ACQ, spirometry and sputum induction will be performed at visit 2. Bronchoscopy will be performed at visit 3, 2-4 weeks after visit 2. Mucosal biopsies, bronchial brushings and bronchial washings will be performed and processed as per our prior methods. Mucosal biopsies will be homogenized and processed for RNA, or fixed for later sectioning and histological examination. Biopsy RNA will be assessed for quality and subjected to RNA-sequencing of all human genes (mRNA-seq). Bronchial washing cells will be collected for differential cell counting and mRNA-seq analysis. Bronchial epithelial cells (BECs) from the brushings will be cultured. BECs treated with CS and inflammatory cytokines will allow comparative assessment of BEC responses.
Asthma is the most common chronic condition among children and many children seek emergency department (ED) care. A key aspect of ED asthma management at the time of discharge is appropriate outpatient referral. Part of the challenge for ED providers is determining which patients require intensive outpatient support as ED providers often do not have the time or familiarity with the asthma guidelines to appropriately stratify asthma severity. Thus, the aim of this study is to determine whether the proportion of children referred to outpatient asthma care can be improved by incorporating a previously validated tool [the Pediatric Asthma Control and Communication Instrument for the Emergency Department (PACCI- ED)] into ED clinical care.
Primary objective: - Describe the characteristics of enrolled severe asthma patients Secondary objectives: - Assess the control of asthma under dupilumab (Dupixent®) treatment until 1 year - Assess the clinical objectives of the asthma care - Assess comorbidities associated with Type 2 inflammation - Assess safety during the year of treatment
This study will be conducted to evaluate the effects of an educational asthma program on the frequency of emergency department visits and identifying factors associated with frequent emergency department visits by asthmatic children and determine its effect on asthma severity and quality of life among asthmatic children and their caregivers.
The purpose of study is to provide an objective data for evaluating the efficacy and safety of Chinese medicine (CM) formula combined with inhaled corticosteroid in the treatment of asthmatic children. Investigators will recruit eighty-six mild to moderate asthmatic children aged 4-11 years old with regular ICS usage and they will be randomized into two groups in this double-blind trial. Forty-three subjects will receive CM (CM group; Ma-Hsing-Kan-Shih-Tang in combination with Liu-Jun-Zi-Tang) and the other forty-three subjects will receive placebo (placebo group; 10% CM) for 12 weeks. Investigators will compare these two groups by questionnaires of Childhood Asthma Control Test (cACT), the Integrated Therapeutics Group Child Asthma Short Form (ITG-CASF), Pediatric Asthma Caregiver's Quality of Life Questionnaire (PACQLQ), the pulmonary function test and blood test including Complete Blood Count with Differential Count (CBC/DC), total IgE, Eosinophil Cationic Protein (ECP) and IL-4/IL-5/IL-13. Adverse events, renal and liver function test will be evaluated to investigate the safety of CM formula as well.
Using "big data" and artificial intelligence techniques, it becomes possible to envision algorithms for managing childhood asthma on a daily basis. In order to develop such tools, it is necessary to determine with asthma stakeholders (children, parents, doctors) the parameters that future algorithms should seek to maximize / minimize. The main objective of the study is to quantify the respective importance of each of the goals that children with asthma, parents, and their doctors seek to achieve when taking / supervising / prescribing a background therapy.
