Abstract
The aim of our study was to evaluate oxidative stress and thiol-disulfide homeostasis in term newborns receiving phototherapy. The study was planned as a single-blind, intervention study in a single center with level 3 neonatal intensive care unit to investigate the effect of phototherapy on the oxidative system in term newborns with hyperbilirubinemia. Neonates with hyperbilirubinemia were treated with total body exposure phototherapy technique for 18 h using a Novos® device. Blood samples of 28 term newborns were taken before and after phototherapy. Total and native thiol, total antioxidant status (TAS) and total oxidant status (TOS), and oxidative stress index (OSI) levels were measured. The 28 newborn patients included 15 (54%) males and 13 (46%) females with a mean birthweight of 3080.1 ± 366.5 g. Native and total thiol levels were found to be decreased in patients receiving phototherapy (p = 0.021, p = 0.010). Besides, significantly lower TAS and TOS levels were found after phototherapy (p < 0.001, p < 0.001). We found that decreased thiol levels were related to increased oxidative stress. We also determined significantly the lower bilirubin levels after phototherapy (p < 0.001). In conclusion, we found that phototherapy treatment induced decreased oxidative stress associated with hyperbilirubinemia in neonates. Thiol-disulfide homeostasis can be used as a marker of oxidative stress due to hyperbilirubinemia in the early period.
