Filter by:It is planned to conduct a study of nitric oxide metabolites (nitrates and nitrites), L-arginine, arginase-1, and asymmetric dimethylarginine in patients with bronchial asthma and chronic obstructive pulmonary disease, followed by observation to assess the prognosis of the disease.
The aim is to test the efficacy of AIM2ACT and long-term maintenance of treatment effects in a fully-powered randomized controlled trial with 160 early adolescents with poorly controlled persistent asthma, ages 12-15 years, and a caregiver
According to the definition provided by the GINA guidelines, asthma is characterized by a variable and reversible limitation of expiratory airflow and by the following symptoms: wheezing, dyspnoea, thoracic constriction and/or cough. The type and the severity of airflow limitation can vary over time (1) depending on external agents, such as physical exercise, polluting agents, climate changes and viral infections. The therapy is mainly based on the use of inhaled corticosteroids and bronchodilators. Patients affected by severe asthma (~ 10% of total prevalence of asthma and at high risk of exacerbations and/or hospitalization) may not control their symptoms, even if exposed to maximal doses of inhalation therapy.The behavioural sciences can potentially help to find the psychological factors behind scarce adherence and to develop strategies with the aim of improving the interactive processes between patients, medical doctors and health care professionals
The SECOND SOUFFLE survey focuses on aspects of care and quality of life in a period when the landscape of severe asthma is changing in the context of biotherapies. Moreover survey on care pathway and quality of life of the asthmatic severe population according to their phenotype have never been done. It is likely to bring results in a relatively fast time, results that can lead to guide the criteria collected in RAMSES a national severe asthma cohort and future research tracks of this cohort.
A double-blinded, placebo-controlled, prospective, multicenter randomized of 2 active treatment groups, compared to 1 placebo group, for the determination of the efficacy and safety of subcutaneous immunotherapy in patients with rhinitis/rhinoconjunctivitis with mild to moderate asthma, sensitised to Dermatophagoides pteronyssinus and /or Dermatophagoides farinae.
The effects of regular exercise on asthma control has not yet been well demonstrated. The aim of this study is to investigate the impact of submaximal physical exercise on quality of life, on symptomatic control, and on bronchial and systemic inflammatory markers in patients with persistant asthma.
Often when people with asthma get a virus caused by the common cold (rhinovirus), they also experience an increase or worsening of their asthma symptoms. The purpose of this study is to see if the study medication dupilumab helps prevent those with mild to moderate asthma from having increased asthma symptoms, after being exposed to an experimental rhinovirus inoculation. This is a study about dupilumab which is a drug approved by the U.S. Food and Drug Administration (FDA) for treatment of moderate to severe asthma. Dupilumab is a medication that blocks pathways that cause asthmatic inflammation in the lungs, leading to symptoms and worsening lung function. During this study, subjects will be given either dupilumab or placebo and will subsequently be exposed to the the "common" cold virus (rhinovirus). The virus that the investigators are using has been safely used before in many studies like this involving thousands of volunteers, and the safe use of the virus in this research study has been reviewed by the FDA. The investigators will track asthma symptoms during the study with lung function tests, questionnaires, specimen collection, biomarkers, and physical exams. For data analysis the investigators will assess the samples collected to determine changes in the treatment groups. The investigators will also asses the symptom scores and deviations from baseline measures for lung function.
To test the preliminary efficacy of the TASC adherence promotion intervention for adolescents with asthma in a feasibility randomized controlled trial compared to treatment as usual control arm.
The anti-interleukin (IL)-5 receptor benralizumab inhibits eosinophilic inflammation but its potential effect on airway remodeling remains unknown. The main objective of this study is to assess the effect of benralizumab in an in vitro model of airway remodeling using cells obtained from asthmatic patients.
Asthma affects 1 in every 12 persons in the U.S., resulting in 1.9 million ED visits annually; however, the impact of ED care on patient-reported outcomes after acute exacerbations is unknown. The proposed research will train a physician-scientist to develop a novel instrument to assess patient-reported outcomes after adult ED asthma visits, evaluate the association between ED clinical processes and patient-reported outcomes, and test the association between patient-reported outcomes and subsequent acute care utilization. The candidate will acquire skills in patient-centered research, instrument development and validation, and risk adjusted outcome measurement that will enable her transition to independence.
