Active clinical trials for "Asthma"

Asthma is the most common chronic respiratory disease worldwide. Despite advances in asthma management, control of the disease is still a challenge especially among children. Information and communications technology (ICT) have been recently used in clinical practice to increase awareness of diseases, encourage patients to engage in the management of their conditions and improve monitoring and surveillance. The investigators of this study will test a new digital platform combining online/offline content aimed to improve asthma control and reduce exacerbations and unnecessary consultations in children with difficult-to-control asthma. A randomised controlled trial enrolling 60 patients allocated in two groups has been designed. The intervention group (IG) will be granted free access during 6 months to a web-based platform. During this period, patient will have access to online/off line content to improve disease awareness, monitor signs and symptoms and will also get the support of a respiratory coach. In addition, patients in this group will receive an electronic peak flow meter to register daily variations in maximal expiratory flow and an electronic device to connect to their inhaler to track adequate intake of inhaled medication. The control group (CG) will receive usual care consisted of scheduled visitations to medical doctors every 4 - 8 weeks. Both groups will be evaluated at baseline, post-intervention (6 months) and at follow up (one year) in the following variables: age, gender, asthma severity classification according to international guidelines, date of diagnosis, weight, height, Body Mass Index (BMI), forced expiratory volume in 1 second (FEV1), Asthma Control Questionnaire score, treatment received for asthma, number of exacerbations in the previous 6 months and concomitant diseases. Exacerbations will be defined as any worsening in asthma symptoms that requires an increase in the usual therapy, an unscheduled physician visit, treatment in the emergency room or hospitalization.

Asthma, a disease characterized by chronic airway inflammation and hyper -responsiveness, is a common disease that affects all age groups. Asthma may be manifested as irreversible airflow obstruction in some patients. Although the pathogenesis of asthma is not well understood, increased oxidative stress due to an imbalance of oxidants and antioxidants has been found to be associated with asthma. In asthma, inflammation-related oxidative stress is driven by exposure to a variety of triggers, including allergens and viruses, which activate components of both the innate and acquired immune responses. Protection by escaping from triggering factors or standardization of asthma medication is difficult and usually is not enough for effective treatment. On the other hand, correction of antioxidative systems may be more efficacious in the control of asthmatic inflammation and asthma symptoms. Little is known about the role of asymmetric dimethylarginine in the pathogenesis of asthmatic airway inflammation. The lung is a major source of asymmetric dimethylarginine that can promote oxidative stress by a reduction in nitric oxide synthesis which would result in higher levels of peroxynitrite, that causes oxidative cell damage, and exacerbate airway inflammation. asymmetric dimethylarginine can modify lung function, increase airway hyper-reactivity even in non-inflamed airways, and promote lung collagen production and deposition. Increased asymmetric dimethylarginine in serum has been found to be associated with the severity of symptoms of asthma in obese adults. Malondialdehyde is an oxidant marker of pulmonary oxidative stress, and lipid peroxidation. Paraoxonase, an antioxidant enzyme may play a protective role in asthma. It hydrolyzes lipid peroxides and prevents low-density lipoprotein oxidation.

Asthma affects 8% of the entire population. 4-5% of asthma sufferers have severe asthma, characterised by recurrent exacerbations (worsening of symptoms leading to the person having a bout of corticosteroids and/or antibiotics), significant symptoms and lack of response to the most widely used therapy, corticosteroids. There is now new types of treatments (antibody drugs) which are licensed to manage severe asthma such as Anti-IL5. There is evidence Anti-IL5 and other similar antibody drugs are effective at reducing asthma exacerbations and reduce the need for oral corticosteroids for those that have severe asthma. However, some patients respond poorly to Anti-IL5 and the investigators would like to find out why this happens. It is hoped that the investigators can identify the mechanism of poor treatment response to Anti-IL5. It is also hoped that the investigators can understand why symptoms worsen to the point of requiring antibiotics and/or steroids (also known as an exacerbation) for those prescribed Anti-IL5.

In the coronavirus 2019 pandemic, on-the-job training for asthma counseling becomes more difficult. Telecounseling as a training platform becomes a mainstream of training during the pandemic. This study is designed to fill the knowledge gap for telecounseling as a training platform for asthma counseling among nurses.

This study evaluates the change in the composition of Volatil Organic Compounds (VOC) in patients treated by monoclonal antibody for severe asthma.

Feilike HeJi is produced by Guizhou Jianxing Pharmaceutical Co. LTD. For the treatment of phlegm heat caused by lung cough phlegm yellow, bronchial asthma, bronchitis, see the syndrome of proprietary Chinese medicine (approval number: Z20025136) approved by the state and the drug from radix scutellariae, radix peucedani, radix stemonae, red gentian root of deal, phoenix tree, spreading hedyotis herb, red tube 7 flavour, with qingrejiedu, antitussive expectorant effect. In order to fully understand the safety of Feilike HeJi in clinical practice and fulfill the responsibility of production enterprises for patients, the production enterprises initiated this study to further evaluate the safety and understanding of the function characteristics of Feilike HeJi in a wide range of people, so as to guide the clinical rational drug use.

The aim of the present study is to explore if the "Health Lung" application of smart phone and portable spirometry "ezOxygen" can further improve asthma control for chronic asthma adult patients with well asthma control (ACT 20~24, but not 25), compared to hospital-based usual care in a medical center.

To Assess the Utility of Impulse Oscillometry on a Differential Diagnosis among the Patients with ACOS,asthma and COPD over Age 40.

This study was designed as retrospective chart review to test our hypothesis whether there are the differences in inflammatory and anti-inflammatory mediators between asthmatic and ACOS patients with small airway obstruction, and COPD

The investigators will compare the circulating fibrocyte proportion in asthmatic patients with obstructive sleep apnea (OSA) and not with OSA In addition, the investigators will compare the expression of epidermal growth factor receptor (EGFR), endothelin A receptor (ETAR) and connective tissue growth factor (CTGF) The association of those factors and annual decline of forced expiratory volume in 1 second (FEV1) will be performed
