Active clinical trials for "Asthma"

Asthma is a heterogeneous disease, usually characterized by chronic airway inflammation. It is defined by the history of respiratory symptoms such as wheeze, shortness of breath, chest tightness and cough that vary over time and in intensity, together with variable expiatory airflow limitation. This definition was reached by consensus, based on consideration of the characteristics that are typical of asthma and that distinguish it from other respiratory conditions . Asthma is a problem worldwide, with an estimated 300 million affected individuals .It appears that the global prevalence of asthma ranges from 1% to 18% of the population in different countries .

Our hypothesis is that radial arterial pulse may reflect the severity and airway function in asthmatics. The aims of this study are to investigate the pulse spectrim of the radial artery in adult asthmatics, and evaluate its correlation with airy inflammation an lung funtion in asthmatics.

The purpose of this cross-sectional survey study is to describe the prevalence of asthma and Rhinitis symptoms among secondary school students in Saudi Arabia.

A questionnaire will be used in order to find out the reasons for poor adherence for long-term treatment in children with asthma. The hypotheses is maternal factors including the knowledge that asthma is a chronic disease and fear to administer inhaled steroids are major obstacles for appropriate adherence.

The objectives of this study are to use the Delphi method to assemble an expert panel representing innovation in asthma treatment, to collect freely suggested recommendation statements concerning OCS tapering (and sub-topics) among severe asthma patients from this panel for peer evaluation, and finally to determine the level of consensus for each statement from the panel as a whole.

The occurence of influenza can be a factor of imbalance of asthma. Asthma patients are recommended for annual influenza vaccination . However there is insufficient vaccination coverage of asthmatic patients despite this recommendation. The aim of this study is to evaluate the rate of influenza vaccination coverage of children with asthma aged from 6 month to 17 years of age followed in pediatric pneumology consultation at the university hospital of Nancy.

This is a cross-sectional observational study on adult asthmatics evaluating the relationship between asthma control and psychosocial factors to include intimate partner violence, stress, anxiety, depression, post-traumatic stress disorder.

Phase I: To develop and validate laboratory urine and blood test for the detection of medications commonly used in the treatment of asthma Phase II: to test the developed assay in the clinic, to determine its practicality to conduct, and its clinical utility in adherence assessment.

This evidence raises the need to determine the assistance quality care in asthma population in the influential area of Hospital Universitario Virgen de la Victoria through the assistance quality care indicators established by GEMA guidelines. The aim of this study is to obtain clinical data that allow to assess assistance quality degree in order to find improvement opportunities to achieve a better control of asthmatic patients within this influential area.

The main outcomes of this study are to establish a cohort of well-phenotyped asthma patients with a recent history of an exacerbation. We aim to describe exacerbation profiles (phenotypes) of the cohort in terms of inflammatory/biomarker profile and bacterial/viral infection status and to compare these with exacerbation events in the sister APEX cohort.
