The goal of this observational study is to determine the prevalence of remission among adults with mild-to-moderate asthma, as well as the factors associated with remission in Thailand. The main question the study aims to answer is: What is the prevalence of remission among adults with severe asthma in Thailand? Participants will complete a questionnaire on asthma symptoms and undergo pulmonary function testing and a blood test once.
Research is being conducted into chronic respiratory diseases, including chronic obstructive pulmonary disease (COPD), asthma, interstitial lung disease, and bronchiectasis. The investigation specifically focuses on sleep-disordered breathing (SDB) in individuals with chronic respiratory disease. SDB encompasses a range of conditions, the most common of which is obstructive sleep apnoea. In obstructive sleep apnoea, periodic pauses in breathing (apnoea) lead to reduced blood oxygen levels. To detect these events, patients typically undergo sleep studies that involve monitoring oxygen saturation, heart rate, and respiratory patterns during sleep. When chronic respiratory disease and SDB coexist, breathing disturbances during sleep may be exacerbated. To identify SDB, sleep studies are commonly used to assess oxygen levels, heart rate, and breathing patterns. The objective of this research is to identify differences between patients with chronic respiratory diseases who have SDB and those who do not. This will be achieved by analysing sleep study data using a novel analytical approach. The aim is to determine whether this method can yield more detailed insights into the underlying pathophysiology of these conditions.
The goal of this clinical trial is to learn if community-based exercise training can benefit patients aged 18 to 85 with diminished cardiovascular and pulmonary function. The main aim of this study is: • Establish a community or home-based fitness training program for patients with cardiopulmonary insufficiency to improve adherence, safety, and efficacy while alleviating the burden on both patients and society. Researchers will compare community-based exercise training to non-exercise training to see if community-based exercise training works to improve cardiovascular and pulmonary function. Participants will: * Engage in community or home exercise training for 40-60 minutes, five times weekly, during a duration of eight weeks. Exercise modalities are primarily determined by the patients' individual preferences and habits, such as brisk walking, running, swimming, cycling, and hiking. * Adjust the exercise intensity according to their cardiopulmonary exercise test and the person's perceived exertion level. * Utilize fitness bracelets or watches to document statistics during workouts and submit them to the experimenter weekly, covering the five days of exercise within that week. * refrain from making any dietary modifications throughout the trial.
Acute asthma exacerbations are an important public health problem and a major cause of disease progression and healthcare burden for people with asthma. Frequent acute exacerbations are likely to be a distinct asthma phenotype. Further research is needed to identify risk factors for frequent acute exacerbations, but previous studies have mostly been cross-sectional studies at a single time point or prospective studies based on smaller sample sizes. Moreover, most of the studies on frequent acute exacerbations have been conducted in severe or refractory asthma, whereas a certain proportion of non-severe asthmatics may also experience frequent acute exacerbations, the risk factors of which remain to be further evaluated. The main objectives of this project are to compare the baseline clinical, inflammatory, pathophysiological, comorbidities, environmental pollutants and meteorological exposure characteristics of patients with frequent acute exacerbations and those with non-frequent acute exacerbations irrespective of asthma severity, and to develop a disease prediction model for frequent acute exacerbations; and to develop a cohort of patients with frequent acute exacerbations of asthma, observe their prognosis and response to treatment, and search for prognostic factors associated with them. The successful implementation of this study will help in the early identification of patients with frequent acute exacerbations, clarify the factors associated with poor prognosis in this group of patients, and thus provide an individualized plan for the treatment and prevention of this type of patients, which is of great significance in achieving good asthma control, reducing the burden of disease, decreasing the cost of healthcare, and saving clinical healthcare resources and costs.
Chronic inflammatory pulmonary diseases, including asthma, chronic obstructive pulmonary disease (COPD), bronchiectasis, cystic fibrosis (CF), primary ciliary dyskinesia (PCD) and interstitial lung diseases (ILD) are characterised by lung inflammation and remodelling. Clinical, functional, microbiological, biological, pathological and prognostic features are highly variable and heterogeneous. Several phenotypes have been described within the same pathology, as similar phenotypic traits between different pathologies, or the coexistence of components of several diagnoses in the same patient, suggesting shared underlying mechanisms that could represent new therapeutic targets, beyond the initial medical diagnosis. The objectives of this prospective study are to analyze the phenotypic characteristics (clinical, demographic, biological, morphological, pathological, and microbiological characteristics) together with respiratory exposures and underlying mechanisms involving airway epithelium and inflammation processes in a cohort of patients diagnosed with asthma, COPD, bronchiectasis, CF, PCD and ILD.
The aim of this project is to study the effect of an intragastric balloon (IGB) on asthma control in obese patients. Obese patients with uncontrolled asthma will be recruited and randomly assigned to two intervention arms : an intragastric balloon combined with diet and exercise versus diet and exercise alone (control group). The primary endpoint will be the proportion of patients with an improvement based on an Asthma Control Questionnaire (ACQ) score ≥ 0.5 at 1 year compared to baseline.
The goal of this intervention study is to assess the effectiveness of low-cost humidity and mold reduction interventions in the home for reducing pediatric asthma. The study will have two groups, a treatment group that receives the healthy home interventions during the study and a second control group that will receive these after the study. We will compare pediatric asthma before and three months after the healthy home interventions are performed.
This is the registry of control participants for patients with various respiratory diseases. We screened healthy volunteers who visited Seoul National Hospital Healthcare System Gangnam Center for routine health check-up, and enrolled patients who agree to participate in the study. The participants undergo baseline questionnaires, provide blood specimen and information of the results of health check-up. We will include participants as controls if they have no significant respiratory symptom and no significant radiographic abnormality. The data from this registry will be compared with those from other registry of various respiratory diseases
Non-communicable chronic diseases (NCDs) affect approximately 30% of the adult global population, significantly impacting respiratory function and quality of life. Pulmonary and cardiovascular rehabilitation has proven to be an effective therapeutic intervention for managing respiratory symptoms and cardiovascular and improving functional capacity in patients with chronic respiratory conditions. The objective of this study is to evaluate the effects of the pulmonary and cardiovascular rehabilitation program on users of the physical therapy service of CECOM of UNICAMP related to functional capacity, quality of life and respiratory variables after 3 months of the program. Candidates for the pulmonary rehabilitation program are users diagnosed with chronic obstructive pulmonary disease (COPD), pulmonary emphysema, pulmonary fibrosis, asthma or other lung disease. Candidates for the cardiovascular rehabilitation program are users diagnosed with: infarction (AMI), myocardial revascularization surgery, coronary angioplasty, stable angina, valve replacement, chronic heart failure and who meet the criteria for phase III of cardiovascular rehabilitation. They should be referred to physical therapy by the cardiologist with complementary exams and exercise test. The program's assessment will consist of: anamnesis, analysis and recording of complementary exams, physical assessment (weight, height, BMI, cardiac and pulmonary auscultation, blood pressure, heart rate, peripheral oxygen saturation, respiratory muscle strength), functional capacity (six-minute walk test) and quality of life (questionnaire). The program will include aerobic exercises on a treadmill or stationary bike with an intensity between 50-70% of the reserve HR, below the ischemic thresholds. It will also include peripheral muscle strength exercises for the upper and lower limbs, in addition to respiratory muscle training for lung disease patients.
Spirometry is now the gold standard technique for assessing lung function in humans. From the shape of a flow-volume curve measured while the patient, trained by the practitioner, performs forced breaths, the forced vital capacity (FVC) and the forced expiratory volume in one second (FEV1) can be deduced and the pulmonologist is able to detect and characterize respiratory diseases as well as to evaluate current treatments. This technique is non-invasive and simple. It is widely available, robust, reproducible and sensitive to intervention. However, it requires proactive cooperation from the patient and only measures global pulmonary ventilation, without locoregional information. An innovative strategy and an original study framework have been developed in the BioMaps laboratory to establish local maps of flow-volume curves across the lung and to jointly analyze ventilatory function and mechanical behavior at any point in the lung: 3D magnetic resonance spirometry. As respiratory mechanics fundamentally supports ventilatory function, this technique should open a new avenue to non-invasively explore lung function while providing a better diagnosis of regional lung diseases.
Asthma is one of the most prevalent chronic respiratory diseases in children, and accurate phenotyping and disease monitoring remain challenging in routine clinical practice. This observational cohort study aims to investigate the clinical value of multimodal tongue and pulse information in the syndrome diagnosis and phenotypic characterization of pediatric asthma. Children aged 5-18 years with a confirmed diagnosis of asthma will be enrolled at Shanghai Children's Medical Center and followed in routine outpatient care. Standardized tongue images and pulse wave data will be collected using validated acquisition devices during visits when lung function testing is performed. Quantitative features extracted from tongue and pulse data will be integrated with clinical information, including asthma stage, lung function parameters, eosinophil counts, allergic sensitization status, and Asthma Control Questionnaire-5 (ACQ-5) scores. The primary objective is to evaluate the associations between tongue-pulse multimodal features and asthma clinical stages and pulmonary function. Secondary objectives include exploring their relationships with airway inflammation and asthma control status. This study seeks to establish a non-invasive, objective, and quantifiable approach to asthma phenotyping, providing evidence for integrating traditional diagnostic features with modern clinical data to support precision management of pediatric asthma.
This is a study to determine the safety, pharmacodynamics (PD), and pharmacokinetics (PK) of CDX-622 in adults with mild to moderate asthma.
Respiratory conditions impose an enormous burden on the individual and the society. According to the WHO World Health Report 2000, the top five respiratory diseases - including asthma and COPD - account for 17% of all deaths and 13% of all Disability-Adjusted Life Years (DALYs). Obstructive lung diseases are among the most common chronic diseases in working-aged populations affecting \~40 million individuals in Europe. The greatest economic burden of respiratory diseases on health services and lost production in the EU is due to COPD and asthma, at about €20 billion each for healthcare and €25 billion and €15 billion, respectively, for lost production. For Norway, there are no estimates of asthma prevalence for the country as a whole, but 80/1000 women and 55/1000 men used asthma medication in 2013 according to the national prescription register. Estimated annual deaths in Norway due to COPD were 4070 in 2015, which is 30% higher than for lung cancer. Unfortunately, a substantial proportion of patients are still difficult to treat. This underlines the need for better primary prevention and more knowledge regarding causes and exacerbating factors. Several risk factors for chronic respiratory diseases are identified, most important tobacco smoke, closely followed by air pollution and occupational exposure. However, according to recent reviews there is a lack of understanding regarding environmental risk factors and mechanisms of how these affect respiratory health, the importance of biological markers and comorbidity, and of socioeconomic risk factors. Moreover, there is a need for assessment of interactions between risk factors and between the individual and the environment. Telemark has a high proportion of craft- and industrial workers providing exposure contrasts. Furthermore, the use of medication against respiratory diseases and the rate of sick leave are higher in Telemark than elsewhere in Norway. Moreover, the county has a high rate of disability. There are previous studies from other parts of Norway, which have estimated the occurrence of respiratory diseases and provided valuable knowledge regarding some risk factors. However, these studies use crude measures of self-reported exposure and do not provide sufficient information on how to target intervention and implement effective prevention. In contrast to the Telemark study, these studies have not included register data or advanced modelling of environmental exposure.
This study is an observational multicenter cross-sectional study. Planned study population consists of 5 000 adult patients with uncontrolled SA receiving treatment according to standard of care (except biologics). Planned number of study site is 50 outpatient centers with experience of uncontrolled SA treatment in about 50 regions of Russia (in order to describe characteristics of patients with uncontrolled SA in different regions in the most comprehensive way). This non-interventional study does not imply any intervention into a routine clinical practice, and does not provide for any diagnostic and therapeutic procedures other than those used in routine practice.
Asthma is a chronic inflammatory disease of the airways that results in tissue remodeling, airflow limitation, and bronchial hyperresponsiveness. This study aims to evaluate the long-term effects of photobiomodulation using an LED vest in the management of pediatric asthma. It is a randomized clinical trial involving children aged 6 to 17 years diagnosed with mild to moderate asthma, divided into two groups: an intervention group (using a vest with active LEDs) and a control group (using the vest turned off, simulating the intervention without light emission). The methodology includes clinical and functional assessments such as spirometry, the Asthma Control Test (ACT), the GINA questionnaire, and the Incremental Step Test (IST), which measures exercise tolerance. Photobiomodulation through LEDs promotes cellular biostimulation without thermal effects, modulating inflammatory processes and optimizing tissue regeneration. It is expected that the LED vest will contribute to improving pulmonary function, enhancing quality of life, and complementing conventional treatments. This project aims to advance the clinical application of photobiomodulation as an accessible and effective therapeutic alternative for pediatric asthma.
The OXIGENE study is a research project that aims to better understand how the immune system behaves in people with lung diseases such as asthma, COPD, pneumonia, tuberculosis, and viral lung infections. By analyzing a single blood sample, the study examines how certain immune cells react during inflammation and infection, and whether lasting changes in these cells influence how strongly the body responds to disease. Although participants do not receive direct medical benefit, the results may help improve future diagnosis and treatment of lung diseases by providing deeper insight into immune responses.
The aim of the study is to evaluate the impact of CPAP treatment on asthma control in patients with severe uncontrolled asthma and obstructive sleep apnea (OSA)
The study aims to demonstrate the superiority of GSK5784283 compared to placebo in reducing the annualized rate of clinically meaningful asthma exacerbations.
Aim 2: Conduct a pilot RCT of SaMBA-WTC to determine feasibility and preliminary impact in preparation for a fully powered trial. (7M-24M) The investigators will conduct a pilot RCT (n=58) of the SaMBA-WTC model vs. an attention control. Data will be collected on the primary outcomes (asthma control \[asthma control test, ACT\], medication use, inhaler technique) as well as on other secondary outcomes including measures of physical function, self-management behaviors, feasibility and fidelity at baseline, at intervention completion at 3 months, and for sustainability at 6 months. This project will prepare the team for all aspects of a subsequent larger efficacy trial of SaMBA-WTC.
