Natural History of Bronchiectasis

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

Background: * Bronchiectasis is a disease characterized by airways that are inflamed, abnormally dilated, and chronically infected. Individuals with bronchiectasis have a history of chronic and recurring respiratory infections. Depending on the underlying cause, these infections may involve the entire respiratory tract, resulting in sinus, ear, and lung disease. * Bronchiectasis continues to be a significant problem in developing countries and in specific groups of individuals, particularly in people who have cystic fibrosis. Although treatments are available or under development for bronchiectasis related to cystic fibrosis, many of the disease-specific treatments may not be effective for bronchiectasis not related to cystic fibrosis. Objectives: \- To study the natural history of bronchiectasis to identify inherited and immune factors that may explain why certain individuals have chronic recurring infections. Eligibility: * Individuals 5 years of age and older who have an established diagnosis of bronchiectasis or a history of chronic/recurring respiratory infections. * Direct family members (e.g., parents, siblings, children) of patients in the study may also be asked to participate. Design: * Potential participants will be screened with an initial clinic evaluation and full medical history, as well as a general quality of life and respiratory symptom questionnaire. * The following standard procedures may be done as part of the study: air sampling from the nose; imaging studies, which may include an x-ray or computed tomography (CT), lung function tests; and collection of samples of blood, urine, and sputum (phlegm or mucus). Other tests may be performed as required by the researchers, and will be explained to patients as needed. * Both patients and relatives (if asked to participate) will provide the following samples: blood or buccal (cheek swab) cells for genetic testing, sputum, and urine. * To prevent infections and potential disease progression, patients may receive standard medical care and treatment for bronchiectasis and related infections during this protocol.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Ages Eligible for Study:5 Years to 100 Years
Sexes Eligible for Study:ALL
Accepts Healthy Volunteers:Yes
Standard Ages:CHILD, ADULT, OLDER_ADULT
Inclusion CriteriaExclusion Criteria
  1. 1. Children age 5 years and above and adults referred to the NIH with chronic or recurring respiratory infections will be eligible for participation.
  2. 2. Males and females will be considered without regard to race or ethnicity or upper age limit.
  3. 3. Emphasis will be primarily on non CF bronchiectasis for elucidation of mechanisms of infection susceptibility. However, select patients with cystic fibrosis or acquired immune defects (such as HIV) may be studied if relevant host defects are suspected, if needed for comparison purposes, or to evaluate and study the management of chronic pathogen associated conditions such as nontuberculous mycobacterial infections or allergic bronchopulmonary aspergillosis.
  4. 4. Subjects must have a primary or referring physician
  5. 5. Subjects must be willing to have samples stored
  1. 1. We wish to avoid enrolling subjects, especially children, who have common respiratory problems (aeroallergen sensitivity, asthma, gastric esophageal reflux) that are not associated with an underlying abnormality in host defenses. Evidence of significance of chronic or recurring infections suggestive of an underlying airway surface or systemic host defense defect should be documented by one or more of the following: a) sinus or lower airway cultures positive for bacterial, fungal, or mycobacterial pathogens characteristic of these defects; or b) radiographic evidence of sinusitis with mucosal thickening and/or air-fluid levels; or c) radiographic evidence of bronchiectasis; d) severity of otitis media requiring placement of tympanic membrane pressure equalization tubes; e) severity of sinusitis requiring surgical intervention.
  2. 2. Patients who are unable or unwilling to provide informed consent either directly or via appropriately designated surrogate.
  3. 3. Any patient who, in the opinion of the Investigator, is unable or unwilling to comply with regular follow-up or is unlikely to provide pertinent information regarding disease progression or response to treatment may be excluded from longitudinal follow-up.
