About this study

Official title: Impact of Respiratory Virus Infections and Bacterial Microbiome Shifts on Lymphocyte and Respiratory Function in Infants Born Prematurely or Full Term

This clinical study will investigate the relationships between sequential respiratory viral infections, patterns of intestinal and respiratory bacterial colonization, and adaptive cellular immune phenotypes which are associated with increased susceptibility to respiratory infections and long term respiratory morbidity in preterm and full term infants. This is a prospective, cohort study, enrolling at a single center via two sites (URMC and URMC-affiliated Highland Hospital and Rochester General Hospital). Enrollment will be accomplished in approximately 15 - 36 months. The study will enroll 280 subjects, 150 pre-term and 130 full-term.

Read the detailed description

This clinical study will investigate the relationships between sequential respiratory viral infections, patterns of intestinal and respiratory bacterial colonization, and adaptive cellular immune phenotypes which are associated with increased susceptibility to respiratory infections and long term respiratory morbidity in preterm and full term infants. This is a prospective, cohort study, enrolling at a single center via two sites (URMC and URMC-affiliated Highland Hospital and Rochester General Hospital). Enrollment will be accomplished in approximately 15 - 36 months. The study will enroll 280 subjects, 150 pre-term and 130 full-term. This protocol does not study an agent or intervention. However, the bronchodilator, albuterol, a beta 2 agonist, will be administered as part of the Respiratory Inductive Plethysmography (RIP) pulmonary function assessments. All infants will remain in the study up to 3 years plus 17 weeks, depending on gestational age at birth. The full-term infants are expected to be typically developing newborns and generally healthy. Enrolled newborns will have a sample of cord blood (CB) for evaluation of lymphocyte phenotype and baseline neutralizing antibody titers. Maternal saliva samples will be collected to test exposure to environmental tobacco smoke. A nose, throat and rectal swab will be obtained for the assessment of the respiratory and gut microbiome and testing for known respiratory pathogens and pathogen discovery. Prior to hospital discharge, infants will have an evaluation of lymphocyte phenotype and function, and will undergo a respiratory assessment via RIP prior to and after a bronchodilator. Co-morbidities, familial and environmental risk factors for atopy, asthma and respiratory symptoms will be assessed. Following hospital discharge, all babies (full-term and former preterm infants) will be followed longitudinally through 3 years CGA as outpatients. During the first year of follow-up, all infants will have rectal and nose, throat swabs obtained monthly. Screening for symptomatic respiratory dysfunction and illnesses will also occur during the time of follow-up as per schedule.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Respiratory Inductive PlethysmographyDevice

    Respiratory Inductive Plethysmography (RIP) will be used to document thoracoabdominal motion, relative minute ventilation, and apnea during the minimally invasive respiratory assessments (NIRAs). Both Full and Preterm Infants will undergo a respiratory assessment via RIP prior to and after a bronchodilator (albuterol)

Questions about this trial

What is this clinical trial studying?

An observational study of Respiratory Tract Infection, run by University of Rochester at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Calculate presence of at/near term gestation cellular immune response to mitogen and antigen specific responses to > /=1 viral pathogens isolated over 1st 2yrs CGA via lymphocyte assessment (time frame: 2 years CGA). The study lists 14 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01789268, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Mar 2022.
