Abstract

Oxidative stress (OS) is strongly involved in the pathogenesis of many fetal and newborn diseases. A low efficient antioxidant systems in preterm babies are not able to counteract the harmful effects of free radicals (FRs), leading to "FRs-related disease" of newborns promoting cellular, tissue and organ damages. The dangerous effects of FRs are linked to their property of being very unstable molecules and their ability to react with lipids, proteins, polysaccharides, nucleic acids, causing functional alterations within the cell, until cell death. OS is difficult to be measured in vivo, because FRs have a very short half-life. Actually, measurements of lipid peroxidation reach high specificity and sensitivity with the discovery of stable compounds, isoprostanes. Recent studies evaluating the damaging effects of FRs in the perinatal period, have observed a direct relation between the degree of OS and the severity of oxidative damage in the course of pregnancy and in perinatal period, with an interesting predictive role of OS biomarkers for diseases resulting from oxidative injury. The validation of a biomarker profile for early identification of newborns at high risk of OS, will pave the way to new clinical preventative or therapeutic approaches to reduce the prevalence of neonatal disability.
