Trial summary

Sepsis has its greatest impact in the prematurely born (preterm) population. Neonatal sepsis (sepsis within the first month of life) causes over one million deaths worldwide annually, and is one of the most common, difficult and costly problems to diagnose, treat and prevent.

About this study

Sepsis has its greatest impact in the prematurely born (preterm) population. Neonatal sepsis (sepsis within the first month of life) causes over one million deaths worldwide annually, and is one of the most common, difficult and costly problems to diagnose, treat and prevent. The preterm infant can suffer rates of sepsis up to 1000-fold higher than the full-term infant, and bears the brunt of the associated mortality and lifelong sepsis-survivor morbidity.

The project is enabled by several novel, validated, microfluidic technologies that are robust and easy to use with little training. These technologies provide comprehensive measures of the functionality of blood PMN population; a critical cellular component of innate immunity. The study team will also extract high-quality nucleic acids from microfluidic-sorted PMNs for transcriptomic analyses. Collectively, these techniques require a total of 250 microliters (µL) of blood, which makes them particularly useful for preterm infants where sample volume is limited, and facilitates serial assessments with unprecedented temporal resolution of key functions of PMNs.

These studies, integrated with bioinformatics approaches, will generate new tools for diagnosing sepsis in the newborn and predicting clinical outcomes. Such approaches have the capability to dramatically change the clinical management of the preterm infant, and potentially improve long-term outcomes while reducing hospital costs.

Read the detailed description

Blood samples will be collected from two populations: preterm infants and term infants.

  1. Preterm neonates (<32 weeks) the study team will collect a baseline 250 µl blood sample on day four of life and then approximately every three days, as is possible, until twenty-one days of life. In addition, for preterm neonates who have suspected sepsis, an additional 250 µl blood sample will be obtained on the day of suspected sepsis. After day twenty-one of life, 250 µl blood will be sampled one time per week until discharge, when a final 250 µl blood sample will be collected. The amount drawn for study related blood collections will not exceed the lesser of 50 ml or 3.0 ml/kg in an 8-week period.
  2. Term neonates (>36 weeks) the study team will be collect a single 250 µl blood sample with the routine screen for metabolic disorders when they are >24 hours old. This will be the only study related blood collection for term neonates.

For all infants, term and preterm, the following data will be collected while the neonate is hospitalized: Demographic information (age, date of birth), past and present medical records, laboratory, microbiology, and all other test results, X-ray, CT, MRI, US and all other imaging test results, records about any medication received during admission, records of physical exam during admission, records of all vital signs and hemodynamic monitoring during admission, records of any procedure or intervention during admission, and condition at the discharge and discharge location.

What participants receive

  • Blood Collection PretermOther

    Blood will be collected on day 4 of life and then approximately every 3 days until 21 days of life. Thereafter, one sample will be collected weekly until discharge. For preterm neonates that have suspected sepsis an additional sample will be collected within 24-48 hours of the initial sepsis evaluation.

  • Blood Collection TermOther

    A single 250 µl blood sample will be collected once the term neonate is >24 hours old.

What is being measured

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

  1. Prediction of Sepsis in Premature Neonates

    The study team will determine whether blood neutrophil migration phenotype using a microfluidic-based approach can be used to predict the onset of sepsis, as well as poor outcome from sepsis, in premature neonates. From peripheral blood, the study team will measure speed, directionality, and persistence of neutrophil chemotaxis using microfluidic devices. The goal is to prospectively identify and validate biomarkers that can stratify neonates who will become septic and have a protracted clinical course. To complement these functional assays, the study team will determine if transcriptomic profiling adds to the diagnostic resolution generated through these functional analyses.

    Measured: Days 4-21

Secondary outcomes (1)
  1. Neutrophil Function of Premature Neonate during Development

    The study team will determine whether premature neonates restore a more normal neutrophil migration phenotype and genomic profile as they reach their developmental milestones during NICU admission

    Measured: Days 22-180
