About this study

Antibiotic resistance is one of the major health threats facing global as well as domestic populations, however it is not well characterized in pediatric patients. Pediatric patients receiving cancer-directed therapy have several risk factors implicated in development of antibiotic resistance including multiple courses of antibiotics, repeated exposures to the hospital environment, indwelling devices and chemotherapy-related damage to mucosal barriers. The investigators propose to capitalize upon the unique position of St. Jude Global within the global pediatric oncology community by using its regional alliance network to describe the molecular epidemiology of antibiotic resistance in Gram-negative bacteria in this population.

Primary Objectives

  1. Describe the epidemiology and the phenotypic and previously determined molecular determinants of antimicrobial resistance in Gram-negative organisms isolated from pediatric diagnostic specimens in selected Central American and US sites with capacity to treat pediatric cancer
  2. Utilize strain typing by whole genome sequencing to describe relatedness between organisms at participating sites
Read the detailed description

Participating clinical microbiology laboratories will flag any Gram-negative bacteria meeting inclusion criteria. Bacteria will be subcultured; one sample will be lysed and shipped to St. Jude; the remaining sample will be stored onsite for the duration of the study. Samples of bacteria from both oncology and non-oncology patients will be included. Whole genome sequencing will be performed on the bacterial samples at St. Jude and the genotypic and phenotypic antimicrobial resistance testing (AST) results compared. Genotypic results will additionally be used to describe phylogenetic relationships and potential transmission events both within and between sites.

Each participating location will collect limited clinical data corresponding to disease and treatment related factors on the affected patient. This will include sociodemographic variables, oncologic diagnosis, treatment phase, presence of a central venous catheter or other foreign body, antibiotic treatment within the past month, and previous history of colonization or infection by a resistant organism.

What is being measured

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

  1. Patterns of organism and resistance in participating sites

    Number of isolated organisms by anatomic site and geographic site

    Measured: approximately 6 months after completion of data collection

  2. Patterns of organism and resistance in participating sites

    Number of antibiotic resistance genes/mutations of interest by geographic site

    Measured: approximately 6 months after completion of data collection

  3. Patterns of organism and resistance in participating sites

    Correlation of known mutations/genes of interest with drug resistance phenotype

    Measured: approximately 6 months after completion of data collection

  4. Genetic relatedness between bacteria at participating sites

    Whole genome sequencing results will be used to describe whether isolated organisms appear to be related phylogenetically.

    Measured: approximately 6 months after completion of data collection

Questions about this trial

What is this clinical trial studying?

An observational study of Antibiotic Resistant Infection, run by St. Jude Children's Research Hospital at 5 sites in 4 countries.

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 3 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in United States, El Salvador, Guatemala, Panama. 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?

Patterns of organism and resistance in participating sites (time frame: approximately 6 months after completion of data collection). The study lists 4 primary outcomes in all. 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 3 Aug 2022.
