Intervention/exposure

Description of intervention(s) / exposure
Within 6 hours of onset of suspected late-onset sepsis or NEC patients will receive Pentoxifylline intravenous infusion 1ml/kg/h for 12h/day (60mg/kg/day) for 2 days followed by 1ml/kg/h for 6hr/day (30mg/kg/day) for 4 days if NEC or sepsis diagnosis is confirmed.

Outcomes
Primary outcome [1] 297331 0
The primary outcome is to describe the pharmacokinetic profile (absorption, distribution, metabolism, and excretion) of Pentoxifylline in preterm infants with suspected sepsis or NEC. Pentoxifylline plasma levels will be determined by means of liquid chromatography-mass spectrometry.
Timepoint [1] 297331 0
At time of suspected or confirmed sepsis or NEC while an inpatient from birth. Four small (0.2ml each) blood samples will be taken before, at 6-12hr, 12-24h and >24h after the start of the initial PTX dose. If they are diagnosed with confirmed or probably sepsis or NEC (based on blood culture, abdominal X-ray and CRP equal or greater than 20mg/L) after 48hr they will continue on PTX for 4 additional days at 6hr/day (30mg/kg/day) and one additional blood sample will be taken once during this time. We will also utilise any leftover blood samples taken for routine blood tests once these are complete. This will allow us to opportunistically analyse and integrate into our analysis the small remaining blood samples that would normally be discarded. The use of a population pharmacokinetic model allows for this utilisation of unplanned samples, unlike traditional pharmacokinetic studies. PTX levels will be determined and the optimal population pharmacokinetics model (with the inclusion of significant covariates such as weight and gestational age) obtained from which simulations of alternative dose regimens will be performed.
Secondary outcome [1] 320746 0
Safety of Pentoxifylline. All enrolled infants will be closely monitored as per NICU guidelines (continuous cardiorespiratory monitoring) and any possible side effects will be assessed and reported to the local ethics committee without delay.
Timepoint [1] 320746 0
Until discharge from the neonatal unit.
Secondary outcome [2] 320795 0
Mortality. Did the baby survive until discharge from the neonatal unit ?

Secondary outcome [3] 320866 0
Need for NEC surgery. Any NEC related surgical intervention will be recorded.
