About this study

Official title: Growth of Airways and Lung Parenchyma

The purpose of this study is to evaluate the growth of the lung and how easily gas can be taken up by the lung in healthy infants born at full term without any breathing problems and infants born prematurely.

Read the detailed description

SPECIFIC AIM # 1: Determine the relationship between parenchymal tissue and alveolar volume with normal lung growth early in life We hypothesize that during the first two years of life that parenchymal surface area and alveolar volume increase with somatic growth; however, the ratio of surface area to volume remains constant, while ventilation within the lung becomes more homogenous.

SPECIFIC AIM # 2: Determine the pulmonary sequelae of premature birth and assess the effectiveness of early treatment strategies upon the pulmonary sequelae.

We hypothesize that premature birth impedes growth and development of the lung parenchyma and the airways at a corrected-age of 1-year. In addition, initiating continuous positive airway pressure (CPAP) and a permissive ventilatory strategy in very premature infants at birth will improve lung growth and lung function compared to treatment with early surfactant and conventional ventilation.

What participants receive

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

Study groups in NCT00419588
Study groupRoleWhat they receive
1-Healthy InfantsGroup 1: We have recruited 50 healthy infants born >37 weeks gestation, and between 2 and 36 months of age. Infants were excluded for any of the following reasons. 1. Congenital cardio-respiratory disease 2. Hospitalization for respiratory illness 3. Treatment with asthma medications for more than one time 4. Small for gestational age at birth 5. More than one respiratory illness 6. More than one episode of wheezing
3-Premature InfantsGroup 3: We will recruit 115 infants born prematurely, 23-35 weeks gestation. Subjects will be evaluated at the corrected age between 2 and 24 months. The subjects will have no oxygen requirements, and be clinically stable outpatients when evaluated. Infants will be excluded for any of the following reasons. 1. Congenital cardio-respiratory disease 2. Severe developmental delay
2-Healthy Infants CTGroup 2: The investigators recruited 50 infants born at > 37 weeks gestation and they were evaluated between 2 and 36 months of age when scheduled for high resolution computed tomography (HRCT) imaging for non-respiratory medical problems. Subjects were enrolled and HRCT of the chest were obtained. Infants were excluded for the following reasons: 1. Congenital cardio-respiratory disease 2. Hospitalization for respiratory illness 3. Treatment with asthma medications

What is being measured

Questions about this trial

What is this clinical trial studying?

An observational study of Infant, Premature, Diseases and Bronchopulmonary Dysplasia, run by Indiana University 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 4 inclusion and 2 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 4 Mar 2020. 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?

Pulmonary function Test (time frame: day of testing). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 4 Mar 2020.
