Objectives Antioxidant response plays a key role in bronchopulmonary dysplasia (BPD) pathogenesis. The glutathione-S-tranferases pi 1 (GSTP1) and cytochrome P450 (CYP) detoxification enzymes protect cells from oxidative damage. The aim of the study was to investigate whether the A(313)G GSTP1 and G(516)T CYP2B6 inactivating polymorphisms could be associated with BPD susceptibility. Study Design To test this hypothesis, we conducted a case-control study enrolled 138 premature neonates ≤32 weeks of gestational age; of the 138, 46 developed BPD and 92 did not develop BPD...

Objective Omega-3 fatty acids are vital for brain and retinal maturation. It is not clear if early use of ω-3 fatty acids in the form of fish-oil lipid emulsions (FLEs) prevents retinopathy of prematurity (ROP) in preterm infants. The aim of this meta-analysis is to evaluate whether early administration of parenteral FLEs reduces ROP requiring laser therapy or severe ROP ≥stage 3 in preterm infants. Methods A literature search was performed to identify studies comparing parenteral FLEs with soybean-based lipid emulsions (SLEs) in preventing ROP...
