About this study

Official title: Prospective, Community-based, Longitudinal Dynamic Birth Cohort Study of Respiratory and Gastrointestinal Pathogen Identification in Brisbane Infants.

In this study, the investigator will be approaching pregnant women to undertake 2 years of weekly respiratory and nappy specimen collection from their healthy new born infant. These specimens will be mailed to the Queensland Paediatric Infectious Diseases (Qpid) Laboratory where they will be stored and batched tested for viruses and bacteria. As well as this, parents will keep a simple daily symptom diary for their child, allowing us to match detection of viruses and bacteria to periods when the study child did or did not have symptoms. This will help our understanding of what finding these viruses and bacteria in specimens from children really means.

Read the detailed description

This will be a prospective, community-based longitudinal birth cohort study of respiratory and gastrointestinal pathogen detection in Brisbane infants. The enrollment target of 138 children will take 2 years to achieve, each child will be followed until their second birthday, and a final year will be required for specimen and data analysis; for a total duration of the study of 5 years.

Women are to be recruited antenatally over a period of two years from study commencement (mid-2010). These hospitals serve communities from the north of Brisbane, a city of almost 2 million people, and every year each has roughly 5,200 (RBWH) and 1,700 (North West) annual deliveries respectively. The investigators will follow 138 infants from birth until their second birthday. Where a family drops out of the study or is lost to follow-up, they will be replaced to maintain overall person-time for the study.

The progressive 2 year recruitment plan allows for seasonal and year-to-year variation in respiratory virus activity. Eligible infants will be healthy term babies without conditions that predispose to more frequent or severe infectious episodes.

Parents will keep a simple, daily, infection symptom diary, completed using tick boxes and numbers, which the investigators will request be returned on a 4-weekly basis. A similar diary was used for a 12-month cohort study conducted in Melbourne (2003-2004) with excellent return rate and acceptability by study families.

Study families are to be contacted monthly by their preferred method of communication (telephone, SMS, or email) to encourage continued performance of study tasks and answer study related questions.

Parents will be asked to identify acute respiratory illness (ARI) and acute gastroenteritis (AGE) in study children. These are defined as:

  • ARI: presence of at least one yellow OR at least two blue symptoms on a single day; and
  • AGE: three or more watery or looser-than-normal stools OR vomiting on a single day.

When an ARI or AGE occur, parents will be asked to complete an impact diary for the duration of illness. Parents will be asked to contact us in the event of hospitalisation due to any cause. Parents will be asked to provide consent for hospital/GP release of information to allow study staff to collect details of episodes of care.

Cord blood will also be collected at birth and stored for later identification of pathogen-specific antibodies and immune mediators linked to disease susceptibility. A respiratory and stool swab will be collected from study neonates within one day of birth. At this visit, the investigators will collect a respiratory swab from the parent/s of the child - this will allow us to compare presence of pathogens in the neonate and parents, and will be the only time parents will be swabbed. Parents will be trained in the process of collecting the study swabs at this visit. All material and instructions required for this process will be provided to parents at no cost. Telephone and visiting support to assist and guide specimen collection will be available for study parents at all stages during the study.

Parents will be asked to routinely collect two specimens on the same day of the week as the initial visit, weekly until the end of the study. The specimens are:

  • a combined anterior nares swab, collected from both nostrils using a single, rayon-budded swab. The swab comes with its own transport tube containing a VTM-soaked sponge in the base. The completed swab is placed in the transport tube and the VTM sponge is squeezed to bath the swab; and
  • a stool swab from a dirty nappy, collected and handled using the swab similar to the anterior nares swab.

Both swabs are mailed back to Qpid Laboratory as soon as possible after collection, using pre-addressed, reply post, padded envelopes.

All specimens will be batch tested for a variety of pathogens using validated PCR methods developed at Qpid. Samples from children with ARI or AGE for whom a known agent cannot be identified, will be made available for further investigations for the presence of as yet unidentified viruses.

What is being measured

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

  1. Acute respiratory illness (ARIs) and acute gastrointestinal (AGE) illness rates per 10,000 child-days in healthy children in the first two years of life

    This measure will be calculated using counts of ARIs and AGE in study children during the first two years of life as the numerator, and person-time in child-months on the study as the denominator.

    Measured: Two years

Secondary outcomes (2)
  1. Pathogen-specific rate of episodes of ARI and AGE per 10,000 child-days in healthy children in the first two years of life

    Viral and bacterial testing will allow to calculate pathogen-specific rates: This measure will be calculated using counts of pathogen-specific ARIs and AGE in study children during the first two years of life as the numerator, and person-time in child-months on the study as the denominator.

    Measured: 2 years

  2. Detection of novel pathogens in healthy children in the first 2 years of life.

    A subset of samples collected during this study will be used to attempt to identify previously undetected pathogens in children, through microarray technology and random primer PCR testing.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

An observational study of Respiratory Tract Infections and Gastrointestinal Infections, run by The University of Queensland at 2 sites in Australia.

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 5 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 31 Mar 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Australia. 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?

Acute respiratory illness (ARIs) and acute gastrointestinal (AGE) illness rates per 10,000 child-days in healthy children in the first two years of life (time frame: Two years). 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 NCT01304914, which also lists 6 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 31 Mar 2016.
