Active clinical trials for "Asthma"

The primary aim of this study will be to evaluate the effects of Lyprinol® supplementation on airway inflammation and the bronchoconstrictor response to dry air hyperpnea in individuals with asthma. The investigators hypothesize that Lyprinol® supplementation, compared to placebo, will significantly attenuate airway inflammation and hyperpnea-induced bronchoconstriction in asthmatic individuals.

The overall goal is to identify best practices for improving health outcomes for patients with asthma using comparative effectiveness research within an Agency for Healthcare Research and Quality (AHRQ) Practice-Based Research Network (PBRN). This goal will be achieved by completing the following aims: (1) Create a centralized database for comparative effectiveness research on asthma by combining clinical and billing data from one of the largest healthcare systems in the country (Carolinas Healthcare System) with data from the school system, Medicaid, and patient and community-level datasets; (2) Deploy a fully developed integrated approach to asthma management based on the Chronic Care Model; (3) Develop and implement a "shared decision making" approach for asthmatic patients from disadvantaged backgrounds; (4) Implement an electronic data collection system for an existing CDC funded school-based asthma intervention that will allow program evaluation and link school nurses with providers; (5) Evaluate and compare the effectiveness of these three asthma management strategies on: overall healthcare consumption and medical costs; quality of life, school absenteeism and performance; asthma clinical measures; and medication utilization; and (6) Disseminate findings across the state via the statewide PBRN and other network partners. This project has the potential to impact over 30,000 asthma patients across the Carolinas including many patients from disadvantaged backgrounds.

Purpose of the study The purpose of this study is to pilot an adapted Coping Skills Training (CST) intervention for feasibility and preliminary efficacy with a sample of children 8 to 12 years of age and their parents. The participants in this study at Children's Hospital of Wisconsin are dealing with one of three chronic health conditions (Rheumatologic Conditions, Epilepsy,Spina Bifida, and Asthma). Research Questions/Study Aims The research questions addressed in the full study are: What is the impact of CST on child depression, QOL, health motivation, attitude toward illness, and self-management efficacy? What is the impact of CST on parent depression, perception of child's quality of life, perception of impact of CHC on family, and family conflict?

The purpose of this study is to determine the effectiveness of a tailored problem solving intervention in increasing adherence to asthma management behaviors in African American adolescents with asthma.

The study will assess the efficacy of a three-part Emergency Department (ED)-based "Asthma Belief and Control" intervention on healthcare utilization, asthma controller medication use, symptoms, and quality of life during the 6 months following an Emergency Department visit.

Bronchial asthma is a common respiratory disease characterized by chronic airway inflammation, which have been affecting about 1-18% of the population in the world, causing tremendous economic burden for the patients and countries. Generally, asthma is a heterogeneous disease, and it could be classified into many types on the basis of symptoms, that is, typical asthma, cough variant asthma, and chest tightness variant asthma etc. Typical asthma (TA) is defined according to the history of repeated respiratory symptoms such as wheeze, shortness of breath, chest tightness, and cough, usually with reversible airflow limitation, airway hyper-responsiveness, and airway remodeling. Cough variant asthma (CVA) is characterized by the single manifestation, recurrent cough, which could be improved after the use of bronchodilators. However, according to different guidelines, it is still controversial on the treatment of CVA and TA. The guidelines of Global Initiative for Asthma(GINA) in 2014 put forward the treatment of TA patients, but did not list the treatment specific to CVA. The guideline of ACCP（American College of Chest Physicians） and cough guidelines of China are proposed to treat the CVA effectively with bronchial diastolic drug. Inhaled corticosteroids (ICS) and leukotriene receptor antagonists are effective for the treatment of CVA. Currently, more and more studies supported that application of ICS combined with bronchial dilation agents is more beneficial to CVA patients. Budesonide/formoterol is a compound of ICS and long-acting beta2-agonist(LABA), which can not only be used as a maintenance medication, but also be used as a relief medication, namely, budesonide/formoterol treatment regimen for SMART (Symbicort as both maintenance and reliever therapy). Most studies show that SMART treatment can be used in the treatment of TA patients. But the study on whether budesonide/formoterol can be used to treat CVA is still little. To provide basis for clinical medication guidance for patients with CVA and TA, this study will enroll 30 patients with TA or CVA , who will be required to adopt the SMART regimen in the following 6 months.The symptom score, airway inflammation, pulmonary function and airway reactivity changes, will be measured every mouth. After the study finished, the investigators will compare the difference between the two groups.

Nocturnal worsening of asthma is common. It is characterized by overnight exacerbation of asthma symptoms such as shortness of breath, chest tightness, coughing, and wheezing, increased need of asthma medications and airway hyperresponsiveness, and decline in lung function (1). Nocturnal asthma has been attributed in part to circadian variations in lung function and airway inflammation. However, other factors including sleep, supine posture and lung volume may also contribute to nocturnal asthma. Current treatments often improve nighttime asthma symptoms. Nevertheless, nocturnal asthma is still common. Up to 2/3rd of asthma patients report nocturnal asthma symptoms, and many asthma related events occur at night, indicating poor asthma control. Results from an ongoing study suggest that in asthma while subjects were supine, fluid shifted out of the legs and accumulated in the thorax (rostral fluid shift) contributing to lower airway narrowing in asthma. A previou study has shown that wearing compression stockings during the day reduces fluid retention in the legs, reduces nocturnal rostral fluid shift out of the legs, and improves sleep apnea (2, 3). The aims of the proposed study is investigate whether off-the-shelf, below the knee compression stockings will attenuate nocturnal fluid shift and lower airway narrowing in asthma.

The anti-interleukin-5 monoclonal antibody mepolizumab is approved as an add-on therapy in Europe, Canada, USA, and other countries, to standard of care for the treatment of patients with severe eosinophilic asthma. Mepolizumab has been shown to reduce exacerbation rates and dependency on oral corticosteroid use in clinical trials in patients with severe eosinophilic asthma compared with placebo, both in addition to standard of care. Other trials had also showed that treatment with mepolizumab resulted in significant improvements in quality of life (SGRQ) and asthma control (ACQ-5 score) . Mepolizumab has only recently been approved in Brazil. There is still no data regarding its efficacy and safety in the Brazilian population and it is important to emphasize that no Brazilian center participated in the previous large, international and multicentric phase III mepolizumab studies. Therefore, it is crucial to perform a local study in order to validate external results in the Brazilian population.

The proposed study will investigate the effect of a polyunsaturated fatty acid / lipid mixture (LCPUFAs) on the clinical symptoms, bronchial inflammation and lung function in allergic asthma in a bronchial allergen provocation (BAP) model. For this purpose, patients with stable episodic asthma and dust mite allergy will underwent BAP before and after supplementation with LCPUFAs. The clinical symptoms, bronchial inflammation, exhaled NO increase and lung function decline (FEV1) will be analyzed.

To compare the efficacy and safety profiles of Fluticasone Propionate 100 mcg and Salmeterol 50 mcg Inhalation Powder (test product) and ADVAIR DISKUS (fluticasone propionate 100 mcg and salmeterol 50 mcg inhalation powder) (reference product) and to show that the efficacy of the 2 active products is superior to that of placebo in the treatment of subjects with asthma.
