Delivery room SLI is more effective than intermittent bag and mask inflation for improving short-term respiratory outcome in preterm infants, without significant adverse effects.
Objective This study aimed to evaluate soluble cluster of differentiation 14 subtype (sCD14-ST), also named presepsin, as an early marker for the diagnosis of culture-proven early-onset sepsis (EOS) in neonates and to assess its relation to disease severity and mortality.
Study Design Out of 60 neonates with risk factors of EOS, 31 neonates were diagnosed as having culture-proven EOS. They were compared with 20 nonseptic controls. We obtained blood samples on day 1 of life for sCD14-ST measurement and sepsis screening. Blood samples were repeated on day 3 in EOS neonates.
Results sCD14-ST was significantly higher in EOS neonates than controls (p < 0.001). Neonates who later developed septic shock had significantly higher day 1 sCD14-ST level than those who did not (p < 0.001). Furthermore, neonates who died had significantly higher day 1 sCD14-ST than survivors (p < 0.001). On day 3, there was a significant decline in sCD14-ST levels than initial levels among survivors. There was a significant positive correlation between day 1 sCD14-ST level and Tollner's sepsis severity score.
Conclusion sCD14-ST could be used as a powerful diagnostic and prognostic marker of EOS. Its quantitative measurement at birth could be a good predictor of sepsis severity and mortality.
Low 25(OH)D level is far frequent among Egyptian preterm neonates. Vitamin D deficiency is an independent risk factor for development of RDS in preterm neonates.
We assessed oxidant-antioxidant status and evaluated the role of lipid peroxidation, oxidative DNA damage, and protein oxidation in the development and severity of neonatal respiratory distress syndrome (RDS). METHODS: Forty preterm neonates with RDS were compared with another 40 preterm neonates without RDS enrolled as controls. Total antioxidant capacity (TAC), malondialdehyde (MDA), advanced oxidation protein products (AOPPs), 8-hydroxy-2deoxyguanosine (8-OHdG), and trace elements (copper and zinc) were measured in cord blood (day 0) for all neonates and repeated on day 3 for the RDS group. RESULTS: Day 0 serum levels of MDA, AOPPs, and 8-OHdG were significantly higher in neonates with RDS than controls with a further increase on day 3. Days 0 and 3 levels of TAC, copper, and zinc were significantly lower in the RDS group compared with controls. Elevated serum levels of 8-OHdG and AOPPs were associated with severe RDS, invasive mechanical ventilation, and high mortality rate. 8-OHdG and AOPPs were positively correlated with MDA, oxygenation index, duration of ventilation, and duration of hospitalization. CONCLUSIONS: Increased lipid, protein, and DNA oxidation is accompanied by alterations in the antioxidant defense status, which may play a role in the pathogenesis and severity of RDS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
