Active clinical trials for "Asthma"

Asthma and COPD have a significant impact on public health, affecting about 8 million people in France and generating health care costs of 5.5 billion euros, almost 50% of which are dedicated to long-term treatments are essentially inhaled therapies. The good control of the disease depends on the patient's compliance, but also on the proper use of the devices used for the administration of inhaled drugs under penalty of the degradation of the control of the disease with major medical and medico-economic consequences. Thus, education of these patients in the use of devices must be an integral part of medical care. It comes up against the complexity of the therapeutic arsenal on the one hand and on the other hand with its time-consuming nature: this makes it incompatible with a realization in consultation. The "ARGOS" process is a telemonitoring project for the support of therapeutic education, consisting in setting up a concrete and real-time relay between prescribers and patients for the education of inhaled therapeutics. Its objective is to provide the answer to what is currently an "unmet need" in the management of asthma and COPD, with the prospect of a positive impact on the observance of these treatments and by consequently their clinical and economic efficiency.

The multiple breath washout (MBW) is one of pulmonary function test that displays flow and gas concentration plotted against time, and shows an exponential decay in end-tidal gas concentration (washout curve). A number of of indices to describe the washout curve have been proposed, the most commonly reported is the Lung Clearance Index (LCI). This is a simple measure of ventilation heterogeneity derived from MBW, that can be used after challenge with a short action bronchodilator and in response to inhaled steroids, both in the conductive airways as acinar. Patients with moderate and severe asthma are characterized by an abnormality in both, conductive and the acinar airway. Therefore the following research question could be: what are the abnormalities in the heterogeneity of ventilation in children with mild and moderate asthma, with respect to the healthy population measured by MBW, and whether these alterations persist after challenge with inhaled steroids and B2 agonists short-acting.

This cross sectional study will be carried out on 30 subjects who will be recruited from the outpatient clinic of Chest Department, Tanta University Hospital. They will be classified into 3 groups: Group I: It will include 10 healthy volunteer subjects. Group II: It will include 10 asthmatic patients. Group III: It will include 10 COPD patients. miR-7, miR-20a, miR-21, miR-22, miR-145 and miR-155 will be measured in serum samples from all subjects

Particulate matter(PM) exposure has been shown to increase the morbidity and mobility of a variety of respiratory diseases, including COPD and asthma. This study focus on the effects of PM on the pulmonary function and acute exacerbation of COPD and asthma patients in China, where PM exposure is much heavier than the United States and European countries.

The study objective is to investigate the safety and effectiveness of Spiriva Respimat in patients with mild to moderate persistent asthma under real-world use

The primary objective of this study is to demonstrate differences in ILC2 blood levels between asthma patients and control patients.

An observational study to investigate the compliance of home nebulizer therapy among children aged 0-14 years old clinically diagnosed with asthma

Smoking occurs frequently in patients with asthma. Recent surveys on smoking prevalence report 21-26% current smokers in populations of patients with asthma. Detrimental effects of active smoking in asthma include worse asthma control, an impaired response to corticosteroids and accelerated lung function decline.

Previous studies have demonstrated that exhaled nitric oxide can be useful to monitor the efficacy of anti-inflammatory treatment as well as to predict a risk of asthma relapse in asthmatic patients. The aim of the present study is to evaluate the time course of exhaled nitric oxide in mild asthmatic patients, stopping regular treatment with inhaled corticosteroids, if it is possible, in relationship with symptoms and lung function.

The aim of the study is to measure the inspiratory flow that the different patient groups (asthmatic children, adults and elderly, as well as chronic obstructive pulmonary disease (COPD) patients) generate through empty Easyhaler (two versions) and Turbuhaler inhalers. In addition, the handling and acceptability of the inhalers will be compared in asthmatic children.
