Filter by:Service men and women returning from deployment are significantly more likely to develop asthma and severe respiratory symptoms from airway obstruction. Why this happens is not well known, but exposure to diesel, burn pits, biomass smoke, and sandstorms are thought to play a role. Ultimately, patients with deployment related asthma develop a complex airway disease that does not respond well to standard asthma medications. Therefore, it is imperative that safe and affordable treatments that could improve quality of life and symptoms are studied. It has been previously shown that adult patients with poorly controlled asthma have an abnormal regulation of an amino acid called L-arginine and airway nitric oxide (FeNO), a gaseous molecule normally produced in the airways of healthy people. In healthy people, nitric oxide is present in amounts that help keep the airways open. However, in some patients with asthma, nitric oxide and L-arginine are often low. The investigators' preliminary data in obese asthmatics show that L-citrulline, which is an amino acid that can be metabolized into L-arginine, improved lung function and asthma control, while increasing the levels of FeNO. This is potentially shifting the paradigm in how investigators think of asthma management, as rising FeNO is often thought of being a bad sign. Based on this, the study investigators hypothesize that an L-citrulline-based drug strategy will normalize nitric oxide metabolism, suppress oxidative inflammatory responses and improve airway function in obese patients with asthma. The study proposal presents a clinical trial approach to treat deployment related asthma patients using L-citrulline as an add-on therapy to improve asthma control. If this confirms the investigators' previous study results, the investigators will be in route for developing the only precision-based therapy available to treat this asthma phenotype. These study results will potentially show that L-citrulline is a safe, tolerable medication that can make a significant impact on the respiratory health of a large segment of our active and veteran population at a reasonable cost.
This study examines the implications of providing hospital-level care in rural homes.
This is a randomized placebo-controlled trial of semaglutide, an FDA-approved therapy for the treatment of type 2 diabetes mellitus and obesity, in adults with symptomatic asthma despite the use of inhaled steroids and with excess body weight. This study will test the central hypothesis that semaglutide will improve asthma control and reduce airway inflammation due to direct effects on the respiratory tract in adult asthma associated with obesity.
Asthma is a chronic respiratory disease whose goal of therapeutic, educational and preventive care is to prevent the onset of acute crisis, the most serious of which are life threatening. A general population survey shows a greater prevalence of asthma in the French West Indies compared to hexagonal France, but there is no data to our knowledge on asthma exacerbations requiring pre and intra-hospital emergency services, nor on the clinical severity or on the adequacy of the therapeutic care. Asthma exacerbations, in particular serious forms requiring immediate admission to the Emergency Department or Intensive Care Unit or leading to hospitalization, can be considered as a failure in the prevention of crisis and therefore disease control. The management of acute or subacute asthma exacerbations is however well codified in expert recommendations, renewed annually by the Global Initiative for Asthma (GINA). These recommendations specify not only the initial care, but also the strategy and modalities of return home and post-emergency follow-up. Recently the French Language Resuscitation Society (SRLF) and the French Society of Emergency Medicine (SFMU) jointly published formalized expert recommendations (RFE) on the management of asthma exacerbations (Le Conte 2019). These RFEs still remain the benchmark in France for adequate management of asthma exacerbations for adults and children. Despite these updated recommendations, field observations often show inadequate care, both in the emergency and in the post-emergency period.
The goal of the ALOHA trial is to investigate the efficacy of improved diet quality following a DASH behavioral intervention that has shown promising results in adults with uncontrolled asthma. DASH stands for Dietary Approaches to Stop Hypertension. This healthy diet is known to help people with high blood pressure manage their health. But physicians do not know if the DASH diet can also benefit patients with uncontrolled asthma. Researchers in the ALOHA study are trying to find out the answer to this important question. Researchers at UIC are studying how 2 asthma care programs compare in terms of helping adults with uncontrolled asthma to improve their quality of life. Researchers also want to learn what might explain the differences in patient outcomes that they may see between the 2 programs. The primary outcome will be asthma-specific quality of life. If the DASH behavioral intervention is found to benefit people with uncontrolled asthma, it would provide a practical, safe, and acceptable public-health intervention in the form of dietary modification to reduce the burden of asthma.
This is a randomised, placebo-controlled, double-blind study to assess the efficacy and safety of Atuliflapon administered once daily over a 12-week treatment period to adult participants with moderate to severe uncontrolled asthma.
The onset of smartphone usage has provided new opportunities for managing patients outside the walls of healthcare facilities. The development of asthma-specific smartphone applications represents an excellent area for partnership between developers and medical teams for delivering therapeutic education at the required time and in a personalised way. Within this context, the overall goal of the AsthmaTrain study is to perform a first, small pilot study comparing a new French-language chat-bot guided asthma patient education programme (the 'Vik' application) with the classic, authority-approved patient education program at the University Hospitals of Montpellier, Montpellier, France. The primary objective is to compare a population of adult patients with asthma and participating in a standard patient education programme with a similar population participating in Vik-guided education programme in terms of change in overall scores on the Asthma Quality of Life Questionnaire (AQLQ).
This study will determine if airway resistance to airflow and pressure, measured by Impulse Oscillometry, is impacted in subjects with vocal cord disorders and whether these measurements are different when compared to subjects with asthma.
The purpose of this open-label 12-month extension study is to continue to characterize the long-term safety, efficacy and immunogenic profile of GSK3511294 (Depemokimab) in participants with severe asthma with an eosinophilic phenotype following completion of clinical studies 206713 or 213744.
Childhood asthma is the most common chronic respiratory disease in childhood. The essence of asthma is chronic airway inflammation and airway hyperresponsiveness.The physiological characteristics of children and adults are very different, and the compensatory ability is very strong. There are often no obvious symptoms at the early stage of attack, or only intermittent or persistent cough of different degrees, without typical chest tightness and asthma.However, at this time, certain physiological indicators such as blood oxygen, heart rate, respiratory rate may have been significantly abnormal.If the disease continues to deteriorate and progresses to decompensation, it can quickly move from an asymptomatic state to a failure stage.Therefore, dynamic and accurate acquisition of real-time vital signs and assessment is of great significance for early warning and improvement of prognosis of asthma attacks in children.Intelligent wearable devices can be used to acquire real-time physiological index data of users, such as heart rate, blood oxygen, exercise and sleep dynamic data.An in-depth analysis of long-term and multi-scene dynamic data before and after asthma attacks can establish an early warning model for children with acute asthma attacks by wearable wrist smart devices, which may provide important help for severity assessment, follow-up tracking and out-of-hospital prevention and control of the disease.
