Filter by:Dietary intervention efficacy trials are distinctly lacking in asthma research. This pilot study aims to provide effect size estimates and justification, clinical trial and intervention feasibility data, and procedural materials for a full-scale randomized controlled trial that will determine the efficacy and mechanisms of action of the Dietary Approaches to Stop Hypertension (DASH)—a recommended dietary pattern based on proven cardiovascular benefits—as adjunct therapy to standard care for adults with uncontrolled asthma.
Individuals with serious mental illnesses (SMI) face high rates of medical comorbidity as well as challenges in managing these conditions. A growing workforce of certified peer specialists is available to help these individuals more effectively manage their health and health care. However, there is little existing research examining the effectiveness of peer-led medical self-management programs for this population. in this trial, participants were randomized to either the Health and Recovery Peer program (HARP), a medical disease self-management program led by certified peer specialists, or to care as usual. Assessments were conducted at baseline, 3 months, and 6 months.
This will be a randomized, double-blind, single-dose, three-period balanced crossover study in adult healthy subjects. Each of the 18 subjects will be randomized to receive a treatment sequence consisting of each of the three treatments (FF 400 microgram (mcg), UMEC 500 mcg and FF 400 mcg/UMEC 500 mcg), in three consecutive periods, with a wash-out period of 7 to 10 days between the periods. The study will include a Screening period (28 days prior to first dose), Treatment period (3 single dose periods separated by two 7 to 10 days washout periods) and Follow-up period (7 to 14 days post last dose). The pharmacokinetic (PK) and safety assessments will be performed during the study at fixed timepoints.
Control of airway inflammation is the cornerstone of asthma management. The aim of the present pilot study was to assess whether, and in which magnitude, a leukotriene receptor antagonist (LTRA) added to a basic treatment of inhaled corticosteroids (ICS) + long-acting betamimetics (LABA) might improve airway hyperresponsiveness and inflammation in well-controlled patients with asthma.
The purpose of this study is to evaluate if stimulating the nerve involved with airway constriction, while undergoing procedures that are known to cause asthma exacerbations, decreases the level of asthma attack experienced.
Patients with chronic obstructive pulmonary disease (COPD) experience breathing difficulties because the airways deep in their lungs become narrowed. COPD patients use inhaler drugs to provide relief from breathlessness. However, current inhalers are inefficient as they deliver a 'coarse-mist' of drug-droplets that do not reach the deep airways. In our study, we will use an inhaler of 'fine-mist' drug-droplets, tagged with a radioactive tracer to track them. We will take images of the lungs to see if the fine-mist droplets reach the deep airways, and assess if this improves the breathing capacity in our patients. Our research may allow the development of new, more efficient inhalers to improve treatment for patients with COPD.
To evaluate the clinical efficacy, safety, tolerability and dose-response relationship, using oral corticosteroid (OCS) modulation, of 3 different doses of VR506 using a twice daily regimen from a new dry powder inhaler (nDPI) for 16 weeks in subjects with severe persistent asthma requiring OCS therapy, i.e. Step 5 treatment as defined by modified Global Initiative for Asthma (GINA) guidelines 2011.
The mission of SARP is to improve the understanding of severe asthma through integrated study of its clinical and biological features and to evaluate their changes over time. The ultimate goal of these efforts is to promote better treatments for severe asthma.
This study assessed the effect on asthma control of different dose levels and regimens of QGE031 in asthma patients that are inadequately controlled with inhaled steroid and beta-2 agonist medication. Safety was assessed also. Comparison was to placebo and omalizumab. Information from this study was planned to support the design of future studies.
In people who develop asthma after the age of 12 and who are also overweigh, there can be an increased burden of asthma symptoms, more flare-ups, and poorly-controlled asthma when compared to normal weight asthmatics. Certain factors are more abundant in the blood of individuals who are obese. One such factor is derived from the metabolism of an amino acid found in your diet, which is known as L-arginine (Amino acids are most commonly known as the building blocks of proteins, the same as the proteins found in food). This factor is called asymmetric dimethylarginine or ADMA. The balance of L-arginine to ADMA may be important to the health of subjects with asthma. The balance between L-arginine and ADMA plays an important role in producing nitric oxide (NO) in the airways. NO is normally produced in the lung and plays a major role in maintaining airways open and functioning normally. Our research has shown that in subjects with asthma who are overweight and developed asthma later in life, the combination of low L-arginine and high ADMA, may lead to lower NO levels. We are asking participants in this study to take L-citrulline, which is converted to L-arginine by your body, as a supplement for a period of one week. We anticipate that L-citrulline will restore NO levels in the airways, by increasing the ratio of L-arginine to ADMA
