Asthma

Background: \- Innate immunity is the process by which white blood cells and other parts of the immune system sense and respond to potential infections by causing an inflammation. Researchers are interested in studying how the body responds to certain environmental factors, and whether the body s response can contribute to chronic illnesses or diseases such as asthma and certain types of cancers. Objectives: \- To examine how specific genes and proteins in blood cells respond to environmental exposures. Eligibility: \- Healthy volunteers between 18 and 45 years of age. Design: * The study will involve one visit of 45 to 60 minutes. * Participants will be screened with a brief physical examination and finger stick to determine if they are eligible to donate blood for the study, and will complete a questionnaire about any medications or other drugs (e.g., cigarettes) they may be taking. * Participants will provide a blood sample for research purposes.

The purpose of this study is to assess the safety and efficacy of brenipatide at different dose levels compared with placebo in participants with moderate-to-severe asthma. Study participation will last approximately 65 weeks, including screening, treatment, and follow-up periods.

Despite the overwhelming focus on genetic and genomic causes of human disease over the past two decades, it has been estimated that genetics is currently known to explain only 20% and 40% of the etiology of common disease. Thus, it is becoming increasingly apparent that human disease is a consequence of both genetic susceptibility and environmental exposures. Importantly, while individuals cannot change their genetic composition, we do have the ability both personally and as a society, to influence our environment, promoting health and decreasing the risk of disease. The Personalized Environment and Genes Study (PEGS) aims to determine how the environment and gene-environment interactions can inform our understanding of human health and disease. As science has evolved, so too has the science of this project. This evolution was reflected in a change in the title of this project from the Environmental Polymorphisms Registry (EPR) to the Personalized Environment and Genes Study (PEGS) to more accurately reflect the science that can be conducted. PEGS is a unique resource because of the depth of environmental phenotyping which includes extensive information from exposome surveys, as well as whole genome sequencing on a significant number of participants in the cohort. While it is small relative to genomic cohorts, none of these have the extensive environmental data that is present in PEGS. In addition, other cohorts with deep environmental data lack the depth of genomic data that is present in PEGS. Importantly, PEGS has already provided important analytic advances that are of great interest to and can be confirmed in larger cohorts such as All of Us. The Personalized Environment and Genes Study (PEGS) aims to provide a resource for environmental health translational research by examining gene-environment interactions in health and disease. PEGS is an extension of two previous efforts where it began as a pilot study, the Environmental Polymorphisms Study (EPS; IRB# 02E9004) and was approved subsequently as a full protocol titled the Environmental Polymorphisms Registry (EPR) (IRB #04-E-N0053 and transitioned to its current ID# 04-E-0053). The EPR was envisioned as a phenotype-by-genotype registry of participants who had donated DNA samples, and who had agreed to be contacted for follow-up clinical translational studies based on their DNA genotypes. At the time, the only information available was a participant s age, sex, race, and ethnicity. Further phenotyping of a participant and/or any biospecimens obtained were investigated during a follow-up translational clinical study on participants recruited based on their genotype (hence phenotype-by-genotype) and the PEGS was the first recruit-by- genotype study at the NIH. Following a period focused on recruiting approximately 15,000 participants to enable genotyping of rare (approximately 1% minor allele frequency) single nucleotide polymorphisms (SNPs), the PEGS Consortium Project was undertaken in 2010- 2011 to examine, using the DNA of nearly 4,000 participants, approximately 700 SNPs in approximately 80 environmental response genes that work in concert with environmental exposures to elicit a phenotype. Several clinical follow-up studies, genotype-phenotype association studies, and publications have resulted from the PEGS Consortium Project. To expand phenotype information available to researchers, the Health and Exposure Questionnaire was administered between 2013-2014. In 2017, a more detailed Exposome Questionnaire which includes questions relating to the external and internal exposome was administered. This was an important resource through which to integrate exposures with genotype-phenotype association studies. Whole genome sequencing has now been performed on approximately 4700 participants who were reconsented for this purpose, as indicated above. Questionnaire data was fully adjudicated and combined in a robust and searchable database. With the increased power of the data available, the project was renamed as the Personalized Environment and Genes Study (PEGS) and rolled out in Sept. 2021.

The purpose of this study is to assess how well JNJ-95597528 works when compared to placebo in adult participants with moderate to severe asthma (long-term condition that affects the airways in your lungs).

Asthma affects the lower respiratory tract (bronchi), whereas chronic rhinosinusitis with nasal polyposis (CRSwNP) involves the upper airways. Despite this anatomical distinction, the upper and lower airways form a continuous respiratory tract and share common pathophysiological mechanisms. Consequently, asthma and CRSwNP frequently coexist, and several therapeutic strategies are effective for both conditions. Given these overlaps, we hypothesize that a multidisciplinary consultation involving both a pulmonologist and an ENT specialist could be more effective than separate consultations for patient care. We also believe that this innovative organization that would benefit the healthcare system. To test this hypothesis, we are conducting a study whose primary objective is to assess whether joint consultations lead to a reduction in oral corticosteroid need over the year following the initial consultation, by enabling more personalized treatment strategies. Secondary outcomes will include the frequency of asthma exacerbations, frequency of ENT-related events, respiratory symptoms, quality of life, and healthcare ressources utilization. We will compare outcomes between two patient groups: one receiving joint consultation from both specialists, and the other managed through standard, separate consultations as per current clinical practice.

This study will evaluate the effect of triple ICS/LAMA/LABA therapy with a BDP/FF/GB 100/6/12.5 µg on asthma control outcomes relative to ICS/LABA therapy with BDP/FF 200/6 μg in a population with asthma poorly controlled.

The purpose of this study is to compare how two different formulations of the study medicine (GSK5784283) move through the body over time (pharmacokinetic \[PK\] study) in healthy adults. The aim of the study is to see how the body processes GSK5784283 and determine if the study medicine is safe, how well it is tolerated by the body and if the study medicines being tested work in the body in the same way.

This study is to find out if an Extra Virgin Olive-Oil-based Water (EVOOW) mix, removes more Fluticasone Propionate (FP) from the mouth than Water alone. 2 strengths of the EVOOW mix will be tested, one with equal parts EVOO and Water (50/50) and one with 3 parts EVOO and 1 part Water (75/25). Removing more FP deposits may help decrease the risk for obstructive sleep apnea (OSA), candidiasis (thrush), and speech and swallow dysfunction. Participants will be on study for up to 3 weeks.

This study will evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and potential efficacy of ENV-294 in adults with moderate to severe asthma who are receiving background treatment with inhaled corticosteroids (ICS) and long-acting beta₂-agonists (LABA). Participants will take oral ENV-294 or placebo once daily for 12 weeks. The study includes a screening period of up to 28 days before randomization to confirm eligibility. Study visits and assessments will be conducted to monitor safety, measure drug levels in the blood, and evaluate effects on asthma control and lung function.

Asthma is a chronic inflammatory airway disease associated with variable airflow limitation and persistent respiratory symptoms. Vitamin D has been proposed as a potential biomarker related to immune regulation, asthma control, pulmonary function, and oxidative stress balance. This prospective cross-sectional observational study aims to investigate the association between serum 25-hydroxyvitamin D \[25(OH)D\] concentrations, asthma control, pulmonary function parameters, and erythrocyte oxidative stress biomarkers among Egyptian adults with bronchial asthma. A total of 200 adult asthma patients will be recruited from Abbassia Chest Hospital, Cairo, Egypt. Participants will undergo clinical assessment, Asthma Control Test (ACT), post-bronchodilator spirometry, serum vitamin D measurement, and oxidative stress biomarker assessment including malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPx), and reduced glutathione (GSH). Participants will be categorized according to serum 25(OH)D concentrations into vitamin D deficient, insufficient, and sufficient groups. No intervention or treatment assignment will be performed. 5\. Detailed Description

The secondary objectives are to determine duration and severity of each acute episode with acute expiratory breathing difficulty, the number of episodes with acute expiratory breathing difficulty, degree of pulmonary hyperreactivity and quality of life within 24 months after study entry.

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.

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.

The primary purpose of this study is to evaluate the effects of Fluticasone Furoate (FF)/ Umeclidinium (UMEC)/ Vilanterol (VI) on lung function compared with FF/VI after 24 weeks of treatment.
