BACKGROUND: Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a protein with anti-atherogenic and vasoprotective effects that has never been studied in newborns exposed to preeclampsia. Our aim was to examine TRAIL serum concentrations in such neonates after birth and during the transitional period.
METHODS: Serum TRAIL levels were measured on the first and fifth day of life (DOL1 and DOL5, respectively) in 38 newborns exposed to early-onset preeclampsia and 38 controls born of normotensive mothers.
RESULTS: TRAIL values on DOL1 and DOL5 did not differ between cases and controls. However, from DOL1 to DOL5 TRAIL levels increased in controls (from 20.54 ± 7.35 to 23.93 ± 11.02 pg/ml, p = 0.044) but decreased in those exposed to preeclampsia (from 25.58 ± 15.74 to 20.53 ± 10.72 pg/ml, p = 0.035). Overall, the relative change of TRAIL values from DOL1 to DOL5 was positively related to birth weight (beta coefficient 0.234, p = 0.042) and inversely related to preeclampsia (beta coefficient -0.241, p = 0.036).
CONCLUSION: Newborns exposed to early-onset preeclampsia present a decrease in serum TRAIL levels during the transitional period. This pattern is exactly the opposite from what is observed in neonates born to normotensive mothers, and most likely points towards a defective mechanism of extrauterine adaptation related to preeclampsia exposure in utero.
IMPACT: Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) levels during the transitional period do not differ between infants exposed to early-onset preeclampsia and controls The pattern of change of TRAIL levels after birth is different; TRAIL decreases in newborns exposed to preeclampsia but increases in controls The decrease of TRAIL levels during the transitional period points towards a defective mechanism of extrauterine adaptation and an altered cardiometabolic profile in newborns exposed to early-onset preeclampsia.
