Filter by:The study will consist of three phases: Phase A: General population survey for estimation of the prevalence of asthma, and prospective collection of resource utilization and quality-of-life data for 12 months, Phase B: comparison of healthcare resource usage collected prospectively to the data collected using administrative data in the population recruited in Phase A, and Phase C: Economic modeling of asthma to extrapolate the findings across Canada and into the future years.
This is a prospective cohort study that aims to determine the current demographics, clinical characteristics, comorbidities, treatment status and exacerbations of asthma patients. The primary objective of this study is to determine the current demographics, clinical characteristics, comorbidities, treatment status and exacerbations of asthma patients. The secondary objectives include: (1) to review the current practices of symptom control assessment, (2) to determine the choice of pharmacological regimen, rate of guideline adherence and real-world clinical practice in managing asthma patients, (3) to evaluate the pattern of lung function parameters (spirometry and forced oscillometry technique [FOT]) in adult asthma patients, (4) to evaluate the effect of ageing on the trend of change in lung function parameters (spirometry and FOT) in adult asthma patients, (5) to identify biomarkers that help to categorize different asthma phenotypes and predict subsequent prognosis, (6) to determine the risk factors of uncontrolled asthma and asthma exacerbation, (7) to evaluate the impact of comorbidities on asthma control. 400 out-patient asthma patients are planned to be recruited and they will be followed up for 3 years.
The investigators' aim was to evaluate the population pharmacokinetics of montelukast in infants and children and define the appropriate dose in order to optimize Montelukast treatment in this vulnerable population.
The purpose of this study is to compare absorption of salmeterol and fluticasone from Salmeterol/fluticasone Easyhaler test products to the commercially available product Seretide Diskus
Asthma, abbreviation for bronchial asthma, is one of the common chronic airways disease that threatens human health. Typical symptoms of asthma are recurrent wheezing, shortness of breath, chest tightness and cough, usually occurring at night or early morning. However, there are still some patients with only persistent clinical manifestations of chest tightness. Concerned about this group of patients, we presented a subgroup of bronchial asthma, namely, chest tightness variant asthma (CTVA). This asthma subgroup usually lacks asthma-specific clinical features such as wheezing, shortness of breath, wheezing, and therefore often misdiagnosed for a long time. In order to further understand the clinical characteristics, pathogenesis, and prognosis of patients with CTVA, we conducted a national multicenter observation study to further understand CTVA. Finally, we plan to clarify whether CTVA is a relatively independent asthma phenotype. Meanwhile, reducing misdiagnosis and perform an appropriate treatment of CTVA.
Physical activity is mandatory to the optimal development and health of children. The presence of asthmatic manifestations may influence the comportment of children and its family toward exercise and practice of sports. There no scientific argument to advice a reduction of physical activity in asthmatic children, but previous studies showed that physical activity is reduced in asthmatic children. The aim of this observational study is to evaluate the existing factors leading to this reduction of physical activity in asthmatic children and their families.
The overall purpose of the study is to compare the patterns of neurocircuitry activation in severe asthmatics vs. mild to moderate and healthy controls. The Investigators hypothesize that neurocircuitry activation increases with asthma severity, producing different neurocircuitry patterns for severe asthmatics than those of mild to moderate asthmatics or non-asthmatics.
Investigators aimed to evaluate the clinical efficacy of integrated traditional Chinese and Western medicine in the treatment of asthma, and to further optimize the prescription of Chinese medicine treatment.
The investigators compared the effectiveness of pulmonary rehabilitation program on asthma control in patients with uncontrolled and partially controlled asthma.
A randomized, multicenter, double-blind, placebo- controlled parallel-group study to determine the efficacy and safety of QAW039, compared with placebo, when added to standard-of-care (SoC) asthma therapy in adult and adolescent (≥ 12 years) patients with uncontrolled asthma with respect to change from baseline in forced expiratory volume in 1 second (FEV1) at the end of 12 weeks of treatment.
