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.

Prospective Multicentre Study on Symptoms in First-onset Bronchial Asthma in Children and Adolescents
Bronchial asthma may present with symptoms other than the commonly reported complaints (cough, chest tightness, shortness of breath and wheezing). Less common symptoms include chronic or recurrent productive cough, inspiratory dyspnoea or recurrent pneumonia. Children presenting with these symptoms are often diagnosed with asthma bronchiale and benefit from antiasthmatic management.

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.

Asthma Symptom Perception Study
Asthma affects 8% of the United States population ages \>60 years and causes considerable harm: older adults are 4 times more likely to die from asthma and have twice the risk of hospitalization. The burden of asthma is notably greater among minoritized older adults. Research suggests that perception of expiratory airflow limitation may be a major determinant of asthma outcomes in older adults, and that older adults are substantially less aware of airway obstruction than younger adults. These observations suggest that perception of airflow limitation is a potential target for improving outcomes of older patients with asthma. The research team completed a pilot randomized controlled trial (RCT) of an intervention that trains older adults with asthma to better perceive expiratory airway obstruction through feedback via peak expiratory flow (PEF) prediction and couples this feedback with motivational interviewing (MI) to promote change in asthma self-management behaviors. Compared to an attention control, the intervention improved PEF, perception of airflow limitation and asthma control. In this project, the research team will conduct a fully powered RCT to test the intervention's efficacy among 300 adults ages ≥60 years with uncontrolled asthma who are on controller medications (daily maintenance or as needed) recruited from underserved inner-city medical practices in New York City. Patients will be randomized to the intervention or a time and attention matched educational control. The intervention and control will be delivered in 3 sessions over 6 weeks. The study will test the impact of the intervention on perception of expiratory airflow limitation in older adults with asthma, examine the efficacy of the intervention for improvements in lung function (PEF), self-reported asthma control (Asthma Control Questionnaire \[ACQ\] scores), quality of life (Asthma Quality of Life Questionnaire \[AQLQ\] scores), and emergency department and hospital use, and test the intervention's impact on mean daily ICS dose used (daily maintenance and as needed). Data will be collected at baseline, 1-month, 6-months (primary analyses of effectiveness) and 12-months post-intervention. In secondary analyses, the research team will test the sustainability of treatment effects with vs. without the booster treatment session (active booster vs. attention control booster) delivered immediately after the 6-month assessment on outcomes at 12-months.

Personalized Environment and Genes Study
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. ...

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....

Airway Redox and Gender Determinants in Severe Asthma
The investigators will study the biologic and chemical differences that cause the greater incidence, and severity of asthma in women as compared to men. Severe asthma affects boys more than girls, while severe asthma in adults is predominantly a disease of women. The investigators aim to identify the processes that occur in the body that are behind the onset of severe asthma in young women during the teenage years, and the resolution of severe asthma in boys. To further evaluate gender influences on asthma, asthmatic women at different stages of their menstrual cycle (period) will be also studied. The investigators aim to use biomarkers to develop testing procedures that will identify different types or characteristics of asthma in men and women; and to follow patients over time to uncover relevant clinical outcomes of biomarkers. The investigators anticipate that they will 1) develop clinically relevant tests to identify unique types or characteristics of asthma and severe asthma; 2) determine outcomes over time of biochemically-defined types of asthma; and 3) identify the reasons for why adult women are affected more than men with severe asthma.

The Extended Salford Lung Study ("Ex-SLS") Data Access Project
The Salford Lung Study (SLS) subjects represent a group of COPD and asthma patients whose disease is extremely well-characterised over a short time period. Subjects in the SLS originally consented for information relevant to the study to be shared with the sponsor (GSK). These data were limited to three years prior to randomisation and the twelve-month interventional treatment period. Broadened access to patients' data would allow SLS subjects' entire disease journey to be researched, presenting a rare opportunity to improve scientific and clinical understanding of COPD/asthma disease risk, treatment and progression. This proposal seeks to collect additional subject-level data from SLS patients via their electronic medical records (encompassing past and future data for up to 10 years from the date of consent) and via a one-off patient questionnaire administered at the time of consent.

A Trial Evaluating Novel Technologies for the Diagnosis of Asthma The LUNG-TECH Trial
This trial aims to evaluate novel diagnostic technologies for asthma in 3 different pathways providing the necessary evidence-base to allow adoption into clinical practice: * Pathway 1 evaluates whether the technology can distinguish between people with asthma and healthy volunteers, and other respiratory conditions in a well characterised secondary-care population and whether the parameters they measure correlate with the current standard diagnostic tests; * Pathway 2 assesses whether the technology can accurately diagnose asthma (either independently or alongside current diagnostic tests) in a primary care population of patients where there is a clinical suspicion of asthma; * Pathway 3 explores the ability of the technology to identify clinically important phenotypic characteristics which are difficult to measure in primary care and/or significantly impact on patient management and treatment The novel technology and devices will be entered into the pathway most suited to their stage of development, with this study design also allowing information collected for participants with a confirmed diagnosis of asthma in pathways 1 or 2 to be included in pathway 3. Participants will undergo the investigations currently used to diagnose asthma as well as using the novel devices being investigated in the relevant pathway.

Addressing Quality of Life, Clinical Outcomes, and Mechanisms in Uncontrolled Asthma Following the DASH Dietary Pattern
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.

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.
