Active clinical trials for "Asthma"

In a private practice setting typical for ambulatory medicine in Germany, asthma staging according to the GINA guidelines will be correlated with "real life" treatment and self management of adult outpatients suffering from asthma. Attitudes concerning adherence, awareness, interest in shared decision making and knowledge about the disease are assessed.

The purpose of the study is to assess the blood and urine concentrations of inhaled formoterol.

The purpose of the study is to assess the blood and urine concentrations of inhaled salmeterol.

The purpose of this study is to determine whether asthmatics have different adenosine receptor expression profiles than healthy controls. We hypothesize that asthmatics will have increased adenosine receptor expression versus control subjects. We also want to study the effects of allergen inhalation on adenosine receptor expression in asthmatics. We believe that adenosine receptor expression will be upregulated after allergen inhalation. Both hypotheses are being tested in sputum and peripheral blood.

The researchers are investigating a novel technique, the multi breath nitrogen washout technique, to measure airway changes in various respiratory diseases.

The Sentinel-001 study aims to identify a combination of biomarkers suitable for triage of breathlessness.

The primary objective of this research is to monitor chronic rhinosinusitis (CRS) symptoms in asthma patients who are undergoing treatment with reslizumab. A secondary objective is to explore whether there are sub-populations that appear to benefit or not benefit from reslizumab in terms of their CRS symptoms.

The purpose of this research study is to collect lung tissue and fluid from two groups of people: those who have severe asthma, and those who do not. These samples will then be tested in a laboratory to identify differences in the lung tissue cells and fluids that may exist between these two groups of people.

Asthma is a chronic illness characterized by inflammation of the airways. Severe asthma is defined in the literature as asthma not controlled by medication. In recent years it has become known that severe asthma is a variable disease and has subtypes relating to the age of onset, type of inflammation and allergy, obesity, etc. Our aim is to characterize the phenotypes of severe asthma population in our clinic and compare the prevalent phenotypes to the phenotypes described before.

The aim of investigator´s clinical trial is to investigate 52 patients aged three to five years with viral-induced asthma and 52 patients aged three to five years with allergic asthma. Over a time-span of 5 years the investigators will explore lung function and bronchial responsiveness. The investigators plan to evaluate long-term clinical history of moderate to severe bronchial hyperresponsiveness in preschool children with asthma. Therefore factors like atopy in children, parental atopy and bronchial hyperresponsiveness will be explored.
