Active clinical trials for "Asthma"

This study aims at determining the patterns of asthma remission, the prevalence of these different patterns, the various factors associated with such remissions and possible recurrences of asthma, in order to determine the mechanisms involved in these processes. The investigators therefore want to document these specificities in subjects in complete remission of their asthma, and those in only symptomatic remission of their asthma, in comparison with mildly symptomatic asthmatic subjects and healthy controls.

This patient follow-up programme was designed to describe the extent of Symbicort use in patients prescribed Symbicort as maintenance and reliever therapy in routine clinical practice in comparison with the already documented use of Symbicort as maintenance and reliever therapy in clinical therapies

In our previous study of Methacholine Challenge Tests (MCT) in preschool children, we found that wheeze detection was associated with significant reduction in flows and vital capacity values. We hypothesized that this finding is associated with trapped-air rather than the children's loss of cooperation/concentration. Objectives: To test this hypothesis by attempting plethysmography measurements during MCT.

To identify risk factors which predispose individuals to develop asthma and other manifestations of allergic disease on exposure to laboratory animals in the workplace.

To develop and implement asthma controlling strategies for inner city and high risk populations.

To develop and implement asthma controlling strategies for inner city and high risk populations.

To investigate whether isocyanate-induced asthma is dependent on isocyanate antigen-driven T-cell mediated, airway inflammation.

This study aims to characterise cough in severe asthma through an observational cross-sectional analysis of patients stratified by inflammatory biomarker profile using a number of subjective and objective cough measurement tools.

Multicenter, cross-sectional study to recruit a random sample of 6000 children via school class registers: 3000 children aged 13-14 years and 3000 children aged 6-7 years.

This study is a cross-sectional, non-interventional study based on existing data (NISed).
