Filter by:This study is designed to identify Felis Catus, or cat hair, sensitive asthmatics who demonstrate a late phase asthmatic response after cat hair inhalation. These subjects may be invited to participate in a planned future study investigating novel asthma treatments.
Introduction: Late-onset asthma in women is characterized by poor disease control and reduced quality of life despite intensive treatment with inhaled steroid and beta2-agonist. The condition is further worsened at menopause due to the loss of estrogen leading to increased asthma exacerbation frequency, increased airway inflammation and decreased lung function. Exercise training may increase disease control of asthma patients, but to what extent the same effect is seen in postmenopausal women with late-onset asthma is unknown. These asthma patients represent a phenotype that is characterized by low eosinophilic airway inflammation, severe symptoms, moderate obesity and poor response to conventional medicine. Thus, our hypothesis is that regular physical exercise is especially associated with an improvement in asthma control in this phenotype. The aim of this project is to test this hypothesis and to assess whether an improvement is associated with reduced local and systemic inflammation, change in heart function, lung function and/or body composition. Study design: 40 postmenopausal women with late-onset asthma are recruited via the outpatient clinic at the Respiratory Department at Bispebjerg Hospital and through advertisement. The participants are randomized 1:1 into two groups. One group performs supervised exercise training (spinning) three times per week for 12 weeks while the other group is a control group. Before and after the intervention asthma control, local and systemic inflammation, heart function and body composition is measured. Results: Analysis will be performed to detect changes within and between the groups before and after intervention. Primary outcome is change in ACQ (Asthma Control Questionnaire). Local and systemic inflammation is measured by changes in bronchial challenge to methacholine, sputum cell count and blood tests. Furthermore, secondary outcomes include change in heart function measured by stress-echocardiography and change in body composition measured by Dual-energy X-ray absorptiometry (DEXA). Conclusion: There are to date no prospective studies that can support recommendations containing asthma rehabilitation with supervised regular physical activity for postmenopausal women. Thus, this study will provide novel understanding of the importance of physical activity in a chronic disease such as asthma.
This study tests the effects of an experimental drug PC945 in people with asthma or other chronic respiratory diseases whose lungs are infected by Aspergillus fungi and Candida yeasts. PC945 may be useful in treating patients infected with Aspergillus as, unlike the usual treatments, it is inhaled into the lung and has been designed to stay there and treat the infection. Participants will continue to receive their usual treatment for their chronic respiratory disease. Half of the participants will receive PC945 and half will receive a placebo. The amount of fungus and yeast in the patients' phlegm will be measured over the course of the study. The study will take place at multiple sites in UK and will include approximately 46 participants. The maximum study duration will be about 16 weeks.
The purpose of this study to determine whether the bacteria inside the lungs of people with asthma can be modified (changed) if they are given an antibiotic and if this change is associated with an improvement in asthma symptoms.
Study of the palatability and acceptability of dexamethasone oral tablets crushed and placed in apple sauce or pudding in comparison with the IV solution mixed with sugar syrup and given orally. It is hypothesized that dexamethasone tablets crushed and administered in apple sauce or pudding will be more palatable and acceptable for pediatric patients receiving dexamethasone for an acute asthma exacerbation or croup.
The purpose of this study was to assess the pharmacokinetics (PK) of fevipiprant (QAW039) delivered as a chewable tablet (CT) in pediatric asthma subjects aged 6 to < 12 years with asthma. The results of this study will support the identification of a fevipiprant dose for subsequent pediatric efficacy studies aiming to provide an exposure similar to that of the to-be marketed adult/adolescent dose. In addition, the first data on safety and tolerability of fevipiprant in this age group was obtained.
The overall purpose of this study was to determine the efficacy of fevipiprant (150 mg and 450 mg once daily), compared with placebo, as add-on to standard-of-care asthma therapy, in terms of avoidance of corticosteroid use over 52 weeks.
Exposure to airborne allergens and pollutants is linked to symptom severity of allergies, asthma and other respiratory problems. In this study an air purifier using photo-electrochemical oxidation technology (PECO) will be used in the home environment of study participants. The investigator will assess the reduction of symptoms from allergic rhinitis/conjunctivitis and asthma.
Guidelines from the American Thoracic Society strongly recommend interval warm-up exercise before planned exercise to reduce exercise-induced bronchoconstriction severity. However, no empirical data on the effects of interval warm-up exercise on exercise-induced bronchoconstriction severity are available in obese asthmatic children, where excess fat exerts such an unfavorable burden on the respiratory system, particularly during exercise. The objective of this study is to investigate the effects of interval warm-up exercise on exercise-induced bronchoconstriction severity in obese and nonobese asthmatic children. Our approach will be to investigate exercise tolerance, respiratory function, and exercise-induced bronchoconstriction severity and the effects of (1) 8x30sec interval warm-up & (2) pretreatment with a bronchodilator compared with a no-treatment control on exercise-induced bronchoconstriction severity in 8-12 yr, prepubescent, obese and nonobese asthmatic children. [Aim]: To investigate the effects of interval warm-up exercise on exercise-induced bronchoconstriction severity. [Hypothesis]: Interval warm-up exercise will reduce exercise-induced bronchoconstriction severity after an exercise challenge test to a similar extent as bronchodilator and better than control.
The purpose of this study is to determine the beneficial effect of n-acetylcysteine (NAC), an inhaled medication that breaks down mucus, on lung function. NAC is a medication approved by the US Food and Drug Administration (FDA) for the treatment of chronic diseases of the respiratory system, including asthma. With CT lung imaging, the investigators seek to identify a subgroup of patients with asthma with a 'mucus' profile. This is a single-arm study which means all participants will receive the same treatment.
