Active clinical trials for "Asthma"

The overall objective of the study is to determine the efficacy of corticosteroids in preventing recurrent wheezing and asthma in high-risk, first-time severe wheezing children with rhinovirus infection, stratified by rhinovirus genome load. The secondary objectives are to determine duration and severity of each acute episode with acute expiratory breathing difficulty, the number of episodes with acute expiratory breathing difficulty, degree of pulmonary hyperreactivity and quality of life within 24 months after study entry.

Asthma is caused by or worsened by different things in different people. It is because of these differences that not all people with asthma respond the same to all treatments and medicines. If the investigators can better identify the changes in the airways or breathing pipes in patients with asthma, the investigators may be able to help patients make better choices about the medicines or treatments that are most likely to work best for each patient. This research study is about one specific factor that is known to affect asthma in some patients. It involves an increase in the activity of an enzyme that is in people's airways. An enzyme is something that helps a chemical reaction to occur. The enzyme the investigators are studying in this research study is called GSNOR (S-nitrosoglutathione reductase) , and when the activity of this enzyme is increased, the result is that there is less GSNO (S-nitrosoglutathione) . GSNO is a chemical that protects people's airways. The initials stand for S-nitrosoglutathione, (pronounced s-nahy-troh-soh-gloo-tuh-thahy-ohn), and it is naturally produced by the body. It has an important role in regulating respiratory function (breathing) and preventing inflammation (swelling) in the respiratory tract (throat, airways, and lungs). The amount of GSNO found in the body is controlled by the enzyme GSNOR (S-nitrosoglutathione reductase). GSNOR breaks down GSNO. Too much GSNOR leads to low levels of GSNO, and that can cause inflammation (swelling) and loss of airway function in some asthma patients. The only way to measure GSNOR levels currently is with a bronchoscopy procedure where a scope is inserted into the patient's airways, often under sedation. This research study is being done to test the accuracy of another type of test that can be done in the doctor's office, rather than in a procedure area. This non-invasive diagnostic test, called a GSNO Challenge test, may be able to identify which asthma patients have increased activity of the airway enzyme GSNOR. The investigators are also studying the phenotypes (observable traits) in asthma patients with increased levels of GSNOR. If this research study is successful, in the future (after this research study is done). The investigators may be able to offer a cost-effective and non-invasive way to identify patients who have higher GSNOR activity levels and offer personalized treatments. The GSNO Challenge test includes giving an investigational drug to breathe in (inhale). The investigational drug is GSNO. "Investigational" means the drug is not approved by any regulatory agencies including the Food and Drug Administration (FDA), and is still being tested for safety and effectiveness. The research is registered with the FDA, but again the GSNO treatment in this study (administered during the GSNO challenge testing) is not an approved treatment or diagnostic test for asthma.

A parallel group, randomized controlled trial to compare the effectiveness of an eight-week Nordic walking program plus three educational sessions and usual care in contrast to three educational sessions and usual care in patients with asthma. The researchers hypothesize that Nordic walking program plus educational sessions and usual care is superior to educational sessions and usual care in terms of exercise tolerance, physical activity, asthma and symptoms control, dyspnea, lung function, handgrip strength, quality of life, quality of sleep, rate of medication intake, treatment adherence, and healthcare use in patients with asthma

Clinical exploring study of Weiyang Yuping Decoction in preventing acute attacks of mild to moderate intermittent asthma Based on the theory of "Preventing disease from exacerbating" in Chinese medicine.

The goal of this pilot interventional study is to learn about the implementation of a home monitoring program (using remote study visits and lung function testing) in children with asthma. The main questions to answer are: Do participants find the program to be feasibile, acceptable and accessible? What factors are associated with completion of the program? Does the program have an effect on asthma control and daytime sleepiness?

This study is a phase 2 study of SHR-1905 in subjects with severe uncontrolled asthma. The purpose of the study is to evaluate efficacy and safety of SHR-1905 in subjects with severe uncontrolled asthma.

Asthma self-management is dependent on support and education. To facilitate self-management have we developed and CE-mark a novel digital self-management system called Asthmatuner (Medituner AB, Sweden).The primary aim of this program is to evaluate if self-management with Asthmatuner improves asthma control more than traditional self-management. RCT with two arms, Asthmatuner or traditional asthma management, during at least 6 months. Thereafter, the study continues to be observational from 6- 12 months. Eligible patients with doctor's diagnosed asthma that are managed within the municipality of Tiohundra and Astrid Lindgren Children's Hospital will be invited to participate. Approximately 800 patients, adults and schoolchildren of the age of 6 years will be recruited.Outcomes: Asthma Control Test, number of exacerbations, unplanned healthcare visits, Medicine Adherence Report Scale and lung function.

Research has over decades showed that marine food carries nutritional characteristics that promote human health. As seen in epidemiological studies and based on in vitro and in vivo studies, it is hypothesized that unrefined salmon oil as dietary supplement have anti-inflammatory effect. However, there is sufficient preliminary data to indicate bioactive compounds effect for clinical use, and further clinical trials investigating effect are needed. This trial will investigate the potential anti-inflammatory effect in adults diagnosed with asthma.

This project consists of a psychological intervention in patients and their families with different chronic diseases in order to carry out a comparative study between medical pathologies to know which are the protective or risk variables for the adaptation to the disease.

Asthma is a chronic inflammatory respiratory disease that affects people of all ages and of both sexes. It is a common disease and is present in 8-10 % of the population. Despite drug treatment, many patients have poor control of their asthma with an impact on quality of life and restriction of daily activities. The purpose of this study in primary care is to investigate if measurement of airway inflammation (FeNO) can improve the treatment results and the overall care of adult patients with asthma. The main question in the study is whether the use of FeNO measurements can reduce the number of deterioration periods. The study is conducted under real clinical conditions where the effect of the intervention is measured (pragmatic intervention study). Eight to twelve primary health care centers with functional asthma / COPD clinics are selected within the Stockholm County and are randomly assigned to two groups with four to six primary health care centers each, an active group and a control group (cluster randomization). Instruments for FeNO measurements are made available to the active group and this group is also trained on FeNO measurements and how the value should be interpreted and used to control the treatment, while the control group continues to take care of their asthma patients as usual. The study can lead to improved treatment decisions and patients gaining an increased understanding of their asthma by being informed on the actual degree of inflammation in the airways. Optimized treatment can provide better asthma control with increased quality of life and fewer periods of deterioration, which results in reduced burden on healthcare and lower costs for patients and society.
