Small Airway Obstruction in Asthma COPD ACOS

The data including spirometry, lung volume, impulse oscillometry, sputum data, demographic characters within 6 months are collected for later analysis. Sputum supernatants and cytospins are used to determine inflammatory and anti-inflammatory responses in those patients.

Phase N/A

VCSIP Follow-up Study

The overall aims of this protocol are to determine whether prenatal supplementation with vitamin C to pregnant smokers can improve pulmonary function and decrease wheeze at 5 years of age in their offspring. This is a continuation of the VCSIP trial, to follow the offspring through 5 years of age. ...

Phase N/A

Multiple Breath Washout a Clinimetric Dataset

Lung Clearance Index (LCI) has been shown to be more sensitive and perhaps more applicable in early stages of lung disease when compared to currently utilised physiological outcome measures, and yet it is not approved by regulatory agencies as a recognised surrogate outcome measure. This may highlight some of the ...

Phase N/A

Sorting and Expression Profiling of Airway Cells From Humans (The SEARCH Study)

The airway epithelium is critical for normal lung function and changes in the epithelium are central to the development of asthma. Precise regulation of gene transcription is essential for airway epithelial cell differentiation and transcription changes lead to many abnormalities seen in asthma. Despite the dominant role of enhancers in ...

Using Breath Metabolites to Determine Specific Virus Infection in Asthmatic Patients

Respiratory virus infections cause a majority of asthma exacerbations in the fall to spring months. Current diagnostic platforms for respiratory viruses have limitations including cost, availability, and invasiveness. The use of noninvasive breath collection to analyze breath metabolites may be used to differentiate virus-infected asthmatics from other causes of acute ...

Phase N/A

Measures of Respiratory Health (MRH)

Functional abnormalities associated with lung disease such as cystic fibrosis (CF) occur in early childhood, but have historically gone undetected until the onset of clinical symptoms, at which point irreversible lung damage may have already occurred (1-3). Consequently, over the last ten years the focus of clinical care has shifted ...

Phase N/A

Mechanisms of Exacerbation of Asthma

In this study, we will explore mechanisms of exacerbation in asthma by careful characterization studies in asthmatics presenting in acute severe exacerbation. Specifically, we will determine the frequency of secretor status in these subjects by blood and saliva testing, and we will also perform a detailed cellular and biochemical analysis ...

Phase N/A

Environmental Polymorphisms Registry

We are establishing a registry-based cohort and repository of biological (e.g. blood, urine,saliva, etc.) and environmental (e.g. household dust) specimens (approximately 20,000 participants) in which the donated specimens are linked to the donor s identities, contact information, and some basic demographics through a personal identification number (PIN). Specimens are available ...

Phase N/A

Stress and Treatment Response in Puerto Rican Children With Asthma

Puerto Rican (PR) children share a disproportionate burden from asthma in the U.S. The investigators have demonstrated that in PR children, a variety of psychological stressors -including physical or sexual abuse, exposure to violence, and parental psychopathology- are associated with worse asthma outcomes. Puerto Rican children also have reduced response ...

Observational Study of Characteristics Treatment and Outcomes With Severe Asthma in the United States (CHRONICLE)

The CHRONICLE Study is a multi-center, non-interventional, prospective cohort study of adults with severe asthma who do not achieve control with high-dose ICS therapy with additional controllers and/or require systemic corticosteroid or monoclonal antibody therapy. This study will provide a contemporary description of the epidemiology and medical management of United ...
