Filter by:The purpose of this study is to assess the effect of one of five possible study medications used in the treatment of asthma on blood plasma cortisol levels in children aged 5-11 years with persistent asthma.
The specific hypothesis for this study is that there are fundamental differences in T effector and T regulatory cell responses in the lung to allergens in allergic asthma (AA) when compared to allergic nonasthmatics (ANA) that account for the difference in clinical responses. We will address this by comparing T cell responses in AA versus ANA subjects. These experiments will correlate T cell responses with measures of airway physiology using state-of-the art lung imaging and examine mechanisms controlling T cell activation in the airways of AA and the function of airway T regulatory cells during AA.
Cat allergies are a major trigger of asthma. Therapies are being developed to control the allergic response to cats. We are interested in measuring a type of white blood cell which is linked to cat allergies, which will help us understand how to use new therapies in people who suffer from cat allergies and asthma. We will study cat-allergic individuals with stable, mild asthma who will be exposed to cat allergens. We will measure various white blood cells, including the cells that are linked to cat allergies, to determine whether the number of these cells changes following cat exposure. These cells will be measured from the blood and bone marrow by removing samples using a needle. These cells will also be measured from the lungs by inserting a bronchoscope into the airways and drawing up fluid containing cells. This study will improve our understanding of the harmful versus protective role of these cat-specific cells, and will allow for development of better drugs for treatment of asthma triggered by cat exposure.
The purpose of this study is to determine the type and degree of inflammatory parameters in peripheral blood of asthma patients compared to analysis of induced sputum. 115 asthma patients visiting the outpatient clinic of the University Medical Center will be included. Blood samples are obtained and sputum induction is performed. Hypothesis: in asthma the analysis of type and degree of inflammation in peripheral blood by changes in phenotypes of leukocytes is at least as reliable as analysis of cells obtained from induced sputum
Asthma is a frequently occurring inflammatory lung disease that affects the whole bronchial tree including the small airways (<2mm). Since the introduction of the solution hydrofluoroalkane (HFA) technology it is possible to generate medication with small particles of approximately 1-2 μm, and therefore to reach the small airways. However, at this moment the investigators have no reliable instruments to identify the asthmatic subjects who particularly benefit from treatment with inhaled small particles. Recently the investigators research group investigated whether provocation with small and large particles AMP is able to identify responders and non-responders to treatment with small and large particles of inhaled corticosteroids. This provocation technique gave promising results but needs further optimization. The aim of this study is to determine the optimal particle size of dry powder adenosine to assess small airway involvement in asthma. Secondary, to provide insight in the associations between the standard test, executed with nebulized AMP, and the new test, executed with dry powder Adenosine.
To provide the efficacy, safety and pharmacokinetics of indacaterol acetate in patients with persistent asthma to support dose selection of indacaterol in fixed dose combination QMF149.
The purpose of this study is to investigate the safety of different doses of sublingual tablets of house dust mite allergen extracts in adults with house dust mite-associated allergic asthma.
Undertake a study of educational intervention in primary schools in Andalusia HYPOTHESIS: There are differences in quality of life associated with asthma (as measured by the questionnaire PAQLQ) and the level of asthma control in students with asthma aged 11 and 12 years who receive an educational intervention with their peers without asthma versus those receiving standard information in schools. OBJECTIVES: To compare the control of asthma symptoms, quality of life in asthma and asthma knowledge among a group receiving an educational intervention delivered by specialist teachers of physical education (MEEF) in Primary Schools (CEIP) and control. MÉTODOS group: Randomized controlled single-blind. POPULATION: Students of 11 and 12 years old in Andalusia Sample size: 258 children / children with asthma for a mean contrast (alpha error of 3.4%. 80% power, a confidence level of 95% considering 20% loss. 2580 students will be enrolled prevalence of asthma 10%) . Conglomerates of the CEIP in urban, rural, public and private-reached. INTERVENTION: Training MEEF with the educational program "Sports and Health Asthma and subsequent delivery, then the students MEEF are 5th and 6th grade ( 3 sessions). CONTROL: The standard instruction in schools. OUTCOME VARIABLES: Quality of life (Juniper) and "control del asthma en niños"(CAN) in asthmatics, Knowledge (NAKQ questionnaire) and attitudes toward asthma (all students and teachers). Pre-intervention (T0), post-intervention at 5-6 months (T1) Independent variables: Sex, suffering or not asthma, intervention / control, type CEIP. STATISTICAL ANALYSIS: Comparison of continuous variables: T Students (If normal distribution) "Mann-Whitney (If non-normal distribution). To study qualitative variables chi-square test (normal distribution) and Kruskal-Wallis ( no-normal distribution).
The mission of the SARP is to improve the understanding of severe asthma through integrated study of its clinical and biological features and to evaluate their changes over time. The ultimate goal of these efforts is to promote better treatments for severe asthma.
The Acetaminophen Versus Ibuprofen in Children with Asthma study will test the primary hypothesis that in preschool children 12-59 months of age with persistent asthma on standardized asthma therapy, the number of asthma exacerbations requiring systemic corticosteroids will be more frequent in children randomized to receive acetaminophen as compared to those randomized to receive ibuprofen on an as needed basis for fevers and pain.
