BACKGROUND: Newborns are at high risk of sepsis. At present there is no definitive "rule in" blood test for sepsis at the point of clinical concern. A positive blood culture remains the gold standard test for neonatal sepsis, however laboratory markers that correlate prospectively with culture positive sepsis could aid clinicians in making decisions regarding administration of empiric antibiotic therapies.
METHODS: This multi-site, prospective observational study will take place in two neonatal intensive care units (National Maternity Hospital and Rotunda Hospital, Dublin). Neonates born at less than 34 weeks will be enroled and informed consent obtained prior to late onset sepsis work up. If at any point subsequently during their neonatal intensive care stay they develop signs and symptoms of possible sepsis requiring blood culture, an additional sodium citrate sample will be obtained. Infants will be categorised into three groups as follows: (i) culture positive sepsis, (ii) culture negative sepsis where an infant receives 5 days of antibiotics (iii) non sepsis. Our primary outcome is to establish if differential platelet/endothelial activation can prospectively identify neonatal culture positive late onset sepsis.
TRIAL REGISTRATION NUMBER: NCT05530330 IMPACT: Preterm infants are a high risk group for the development of sepsis which is a major cause of mortality in this population. Platelets have been associated with host response to invasive bacterial infections both in animal models and translational work. A positive blood culture is the gold standard test for neonatal sepsis but can be unreliable due to limited blood sampling in the very low birth weight population. This study hopes to establish if platelet/endothelial associated plasma proteins can prospectively identify late onset neonatal sepsis.
