Chronical Illness-related Limitations of the Ability to Cope With Rising Temperatures, Third Wave

The CLIMATE-III Observational Study examines to what extent chronically ill patients experience adverse health effects because of heat and whether the patients' specific health behavior, somatosensory amplification, risk and benefit perception, self-efficacy, health literacy, and the degree of urbanisation of the patients' administration district are associated with these effects. Study participants from Germany and Italy will be included in the sample.

Agricultural Health Study Follow-up

Background: \- The Agricultural Health Study (AHS) is looking at the long-term health effects of farming exposures including pesticides, crops, and animals. The chronic health effects of exposure to pesticides are easier to study in farmers and their spouses. They know what chemicals they use and tend to live in the same place for most of their adult lives. AHS participants are expected to report any changes in their health. This includes any new medical conditions. Researchers want to follow up on these reports to confirm their accuracy. Objectives: \- To follow up AHS participants who have self-reported that they have a new disease and confirm their diagnosis. Eligibility: \- Current AHS participants. Design: * Researchers will confirm self-reported changes in medical conditions by contacting the AHS participant to ask for more information. * The AHS participant will give permission for researchers to contact their doctor to look at their medical records. They will also be asked to provide a cheek swab or saliva sample. * Diseases of interest are rheumatoid arthritis, lupus, and Sjogren s Syndrome. Other diseases will be followed up in the future. Other diseases will be followed up in the future.

The purpose of this study is to evaluate the impact of inhaled ARO-RAGE on the late asthmatic response (LAR) following an inhaled allergen challenge in participants with mild atopic asthma.

A Study of Acupuncture for Treating Asthma

Asthma is a common chronic respiratory disease with a low clinical control rate, highlighting the need for novel therapeutic strategies. Recurrent asthma attacks emotional symptoms, such as anxiety and depression, etc. On the contrary, symptoms such as anxiety and depression worsen asthma control. Acupuncture is commonly applied as an effective traditional Chinese medical therapy for asthma. Acupoints GV14, BL13 and BL12 are adopted for the intervention of asthma. GV20 and GV29 are selected to improve emotional symptoms including depression. Nevertheless, standardized therapeutic regimens of acupuncture for asthma and its concomitant emotional symptoms are still lacking. 180 patients with mild to moderate asthma will be recruited in this multicenter randomized controlled trial, randomly assigned to the true acupuncture group, sham acupuncture group and usual care group. The primary outcome is the score of the Asthma Control Test (ACT). Secondary outcomes include the Hospital Anxiety and Depression Scale (HADS), Asthma Quality of Life Questionnaire (AQLQ), pulmonary function, and fractional exhaled nitric oxide (FeNO). The superiority of combined acupuncture therapy in improving asthma control, relieving negative emotions, and enhancing quality of life is to be verified in this study, with high quality evidence for acupuncture treatment of asthma thereby to be provided.

Effects of Abdominal Binder on Dysnea, Control Pause and Quality of Life in Asthmatic Patients

This study investigates the effects of using an abdominal binder as an adjunct to diaphragmatic breathing in asthma patients. The goal is to determine if the binder improves respiratory mechanics, specifically reducing dyspnea ,and increasing breath-hold time (control pause) and quality of life over a four-week period

The Development of the Walsh Asthma Self-management Programme and Feasibility of Implementation in Adults With Asthma in Primary Care

Asthma is a common medical condition in Ireland. Adult patients tend to have periods when their asthma is stable and periods when it worsens. In order to reduce these periods of worsening asthma, effective ongoing management is required day to day by adults with asthma. Teaching adults how to manage their asthma effectively, plays a huge role in improving their asthma and having a better overall quality of life. This education on managing asthma has many different parts to it. Most adults will discover they have asthma through their general practitioner (GP) and it will be continued to be checked and managed through their GP or general practice nurse (GPN) in their primary care clinic for the duration of their lives. This research study is taking place to find out if a new education programme, will help adults manage their asthma better and improve the symptoms of asthma, reducing its overall impact on day-to-day life. This study is also looking at how easy it is to introduce and for nurses to deliver this study within a GP/ primary care centre. This study is to find out if this education programme works in a real life setting and if it can lead to better control of asthma for adults.

Study of Lunsekimig (SAR443765) Compared With Placebo in Adults With High-risk Asthma

This is a parallel-group, Phase 2, randomized, double-blind, placebo-controlled, 2-arm study for the treatment of asthma. The purpose of this study is to assess the efficacy, safety, and tolerability of add-on therapy with subcutaneous (SC) lunsekimig compared with placebo in male and female participants (aged 18 to 80 years, inclusive) with asthma, who are not currently eligible for biologic treatments. Study details include: * The study duration will be approximately 64 weeks for participants not transitioning into the LTS study and approximately 60 weeks for participants transitioning into the LTS study. * The investigational treatment duration will be up to approximately 52 weeks. * The number of visits will be 18.

Assess Accuracy of Primary Care Asthma and COPD Diagnosis Using Oscillometry and FeNO vs Specialist Diagnosis

Current diagnostic methods for asthma and chronic obstructive pulmonary disease mostly depend on pulmonary function tests, especially spirometry. While spirometry is a foundational tool, its diagnostic accuracy is often limited by the patient's ability to perform forceful breathing maneuvers, as well as technical and reproducibility challenges, and the need for proper equipment and training. These constraints can compromise effective diagnosis of asthma and COPD in primary care settings. Prompt and accurate diagnosis by primary care physicians is essential for better patient outcomes. Although variable airflow limitation often measured as a change in FEV1 after bronchodilator is a hallmark of asthma, inconsistencies in test quality and reversibility criteria create challenges in distinguishing asthma from COPD. These complexities highlight the need for alternative diagnostic tools beyond traditional spirometry. This observational study is designed to evaluate the diagnostic accuracy and technical feasibility of using oscillometry and FeNO testing in primary care for suspected asthma and COPD, compared to conventional specialist-based diagnostics. The study will be conducted across 6 countries in the MEA, Asia, and Latin America, with two hospital sites per country. Primary care physicians will be trained in oscillometry and FeNO testing using standardized protocols and tools such as the Ambulatory Lung Diagnosis System following GINA and GOLD guidelines. Eligible patients will provide consent, complete a history and symptom questionnaire, and undergo primary care-based assessment for a provisional diagnosis. If specialist assessment cannot occur the same day, it will be done within three days. No follow-up visits are planned. Study outcomes will inform the feasibility and accuracy of integrating these methods into routine care, aiming to improve the early and reliable diagnosis of asthma and COPD.

Asthma and Technology in Emerging African American Adults

The purpose of the ATHENA Project is to test a mobile health intervention to help African American young adults better manage their asthma. The program has four components: 1) a web-based, mobile asthma program delivered to participants' mobile device, 2) meetings with an asthma nurse via video conference, 3) text messaging, and 4) physical activity tracking. Participants will be randomly assigned to one or more of these components to better meet the needs of young adults with asthma.

Boosting Referrals to Asthma Specialists for Patients Seen at the Emergency Room for an Asthma Exacerbation

This study is testing a new way to help adults with asthma get follow up care after an emergency room (ER) visit for an asthma attack. Many people who come to the ER for asthma never see an asthma specialist afterward, even though specialists can offer treatments such as advanced inhalers or biologic medicines that may prevent future attacks. The study will compare two approaches. One group will receive a telehealth appointment with an asthma specialist that is scheduled for them before they leave the ER. The other group will receive the usual care, which typically includes a standard referral but no scheduled appointment. All participants will be offered a prescription for standard controller medication at discharge. The main question the study aims to answer is whether arranging a telehealth visit directly from the ER increases the number of patients who complete a follow up appointment with an asthma specialist within three months. The study will also look at whether this approach improves asthma control, reduces repeat ER visits, and helps patients better understand and use their asthma medications. This research may help identify a practical way to improve access to asthma specialists and reduce the burden of asthma for patients who frequently rely on emergency care.

A Study to Test if a Fixed-Dose Combination of Fluticasone Propionate/Albuterol Sulfate is Effective in Preventing Asthma Exacerbations

The primary objective of the study is to assess the efficacy of high dose fluticasone propionate (Fp)/albuterol sulfate (ABS) integrated electronic module multidose dry powder inhaler (eMDPI) compared to ABS eMDPI in decreasing severe clinical asthma exacerbation (CAEs). Secondary Objectives: To evaluate the efficacy of Fp/ABS low dose compared to ABS and the effect on systemic corticosteroid (SCS) exposure To evaluate the safety and tolerability of Fp/A BS The duration for each participant will be a minimum of 28 weeks including 2 weeks of screening, 2-4 weeks of run-in period and a double blind treatment period of minimum 24 weeks, however due to the event-driven nature of this study, the duration may range up to approximately 42 months depending on the timing when the participant was enrolled to the study, and when the study reaches its completion criteria

The purpose of this study is to assess the pharmacokinetics (PK) and safety of symbicort aerosphere and symbicort pressurized metered dose inhaler (pMDI) in participants with asthma aged 4 to less than 12 years.

Efficacy of Dupilumab Added to Medium Dose Inhaled Corticosteroid/Long-acting Beta-agonist (ICS/LABA) in Comparison to ICS Dose Escalation to High Dose ICS/LABA in Adolescent and Adult Patients With Uncontrolled Asthma

This study is researching a drug called dupilumab. The study is focused on patients who have uncontrolled asthma. Asthma is a condition where the airways narrow and swell, making it difficult to breathe. Uncontrolled asthma means that patients are still having frequent symptoms while taking their current asthma medication. The aim of the study is to see which regimen is more effective: taking dupilumab with an inhaled asthma medication or only taking a higher dose of the inhaled asthma medication. The type of asthma medication that will be used is a combination inhaled corticosteroid and long-acting beta-agonist (referred to as an ICS/LABA). Some patients may also receive an additional asthma medication called a long-acting muscarinic antagonist (referred to as a LAMA) if they are already receiving a LAMA. The study is also looking at: • What side effects may happen from taking dupilumab

Role of Genetic Factors in the Development of Lung Disease

This study is designed to evaluate the genetics involved in the development of lung disease by surveying genes involved in the process of breathing and examining the genes in lung cells of patients with lung disease. The study will focus on defining the distribution of abnormal genes responsible for processes directly involved in different diseases affecting the lungs of patients and healthy volunteers. Optional CT Sub-study The standard CT scan will be compared to the low dose radiation CT scan for the 150 subjects enrolled in the sub-study to assess the variation between the two techniques. Specifically, the quantitative computer aided detection of lung CT abnormalities from LAM can be compared to assess whether low radiation dose CT exams is an alternative to conventional CT to monitor disease status. This optional sub-study will be offered to up to 100 adult subjects with lung disease and up to 50 children age 9 and older with CF. Children will not be enrolled in the optional CT sub-study unless they have had a standard CT scan for medical purposes to use in comparison. One additional low dose radiation CT scan of the chest may be done as part of this sub-study when these subjects have their next annual CT scan.

NHALES (Natural History of Asthma With Longitudinal Environmental Sampling)

Background: \- Asthma is a serious clinical and public health problem. Researchers want to collect data to better understand how bacteria and other things in the environment can affect people's asthma. Eligibility: \- Nonsmoking adults age 18 - 60 who have moderate to severe asthma. Design: * Participants will complete a medical history form before the first visit. * Study visits will include collecting medical history, and conducting physical exam, lung and smoking tests. Participants will give blood, urine, stool, dust, saliva, and sputum samples. * Participants will take tests that measure their breathing abilities. They will give saliva samples for DNA study. They will get kits to collect stool and dust samples at home. They will fill out surveys. * Participants will have visits every 6 months for 5 years. They can schedule sick visits, if needed, at no cost to the participant. For all visits, they will have asthma check-ups and get treatment, at no cost to the participant. * Some participants may take part in a sub-study that includes one 4-hour visit. They will have medical history, physical exam, and lung tests. They will have urine tests to check for pregnancy and tobacco exposure. Then they will have bronchoscopy. For this, an intravenous line will be placed in an arm vein. The nose and throat will be numbed. A flexible fiber-optic tube will be inserted into their airways through the nose. Their airways will be examined and areas of their lung will be washed. A small sample of cells will be taken.

Sample Collections From the Airways of Asthmatic Patients

Fiberoptic bronchoscopy is a procedure which involves passing a pencil-thin tube into the lung in order to collect fluid and cells from the airways. Fiberoptic bronchoscopy can collect cells from the walls of airways by gently brushing them (bronchial brushing). In addition, squirting small amounts of sterile water in to the airway and gently suctioning it back into the bronchoscope (bronchoalveolar lavage) collects cells. In this study, researchers plan to perform these tests on patients with asthma and normal volunteers. This research may help to improve the understanding of the processes involved in airway inflammation and asthma.

A Study to Evaluate Brenipatide Compared With Placebo in Adult Participants With Uncontrolled Moderate to Severe Asthma

A Dose Finding Study With an Anti-TSLP Antibody (GSK5784283) in Adults Aged 18 to 75 Years of Age With Uncontrolled Asthma

This study is trying to find the right dose of a long-lasting medicine called GSK5784283 for people with asthma that remains uncontrolled even though they are using regular asthma treatments. GSK5784283 blocks the action of an inflammatory protein called TSLP that may be contributing to your asthma. The study will be conducted in two parts - Part A (dose finding phase) and Part B (extended dosing phase). Part A will assess the lung function, asthma control, participant safety and certain markers of asthma inflammation in the air you breath out and in your blood. Part B will assess the safety and long-term effects of the repeated or single doses of GSK5784283.

Longitudinal Observational Study of Severe Asthma

Background: \- Asthma is a lung condition that causes difficulty breathing and decreased lung function. Some people with asthma have more severe disease symptoms. They may be less responsive to standard treatments such as steroids. Researchers want to compare severe asthmatics with mild or moderate asthmatics or people without asthma over a long period. This information may help identify new treatments for people whose asthma is not well controlled by standard medications. Objectives: \- To compare severe asthmatics with mild or moderate asthmatics, and healthy volunteers, to study the progression and outcomes of the disease. Eligibility: * Individuals at least 18 years of age who have been diagnosed with asthma for at least 1 year. * Healthy volunteers at least 18 years of age. Design: * This study will involve an initial visit to the NIH Clinical Center for all participants. Selected participants may be asked to return for repeat visits over a number of years. The test results from participants with asthma will be compared with those from the healthy volunteers. * All participants will be screened with a physical exam and medical history. * Participants may (but will not necessarily) have the following tests at each visit: * Complete medical history and physical exam * Blood, urine, sputum, and nasal cell samples * Breath tests and heart and lung function tests * Six-minute walk test to measure ability to exercise * Imaging studies such as chest x-rays, bone density scans, and sinus scans * Allergy skin testing * Vocal cord exam * Overnight sleep study * Participants may remain on the study for as long as they are willing to participate and do not develop health problems that will interfere with the study.
