About this study

Official title: Prolonged Apnea and Prolonged Bradycardia Following DTaP Immunization in Preterm Infants: A Randomized Multicenter Study

The purpose of this study is to examine the relationship between receipt of DTaP and the occurrence of prolonged episodes of apnea and bradycardia in preterm infants, while employing a random control study design and an objective assessment of cardiorespiratory events.

Read the detailed description

The American Academy of Pediatrics (AAP) recommends the immunization of preterm infants at two months chronological age with the diphtheria-tetanus-acellular pertussis (DTaP) vaccine, regardless of birth weight and gestational age. However, several investigators, employing historical controls and subjective observations, have reported an increased incidence in prolonged apnea and bradycardia in preterm infants following immunization. Consequently, many primary care providers do not adhere to recommended AAP guidelines. The purpose of this study is to reexamine the relationship between receipt of DTaP and the occurrence of prolonged episodes of apnea and bradycardia in preterm infants, while employing a random control study design and an objective assessment of cardiorespiratory events.

Ten participating hospitals will enroll infants < 37 completed weeks gestational age into the study when they are 56-60 days chronological age. Infants are randomly assigned into one of two groups: One group receives DTaP immunization and the control group does not (until study is completed). Physiological event recording monitors are used continuously during the next 2 days to document the incidence of prolonged apnea (respiratory pause of ≥20 sec in duration or >15 sec in duration if associated with bradycardia for ≥5 sec) and prolonged bradycardia (heart rate <80 bpm that lasted ≥10 sec) in all infants. The presence and number of episodes during the 48-hour period will be compared between the 2 groups.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Bedside recording of apnea and bradycardia with events verified by 2 independent scorers who were blinded to the study phase and immunization status of the subject.

Questions about this trial

What is this clinical trial studying?

A study testing Infanrix and Pediatrix in people with Prolonged Apnea and Prolonged Bradycardia, run by American SIDS Institute at 10 sites 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 3 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 5 Jun 2007. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites 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?

Bedside recording of apnea and bradycardia with events verified by 2 independent scorers who were blinded to the study phase and immunization status of the subject. (time frame: Six days (Three 48-hour periods).). 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 NCT00482781, which also lists 1 linked publication.

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 5 Jun 2007.
