Potential Peripartum Markers of Infectious-Inflammatory Complications in Spontaneous Preterm Birth

الملخص EN

Spontaneous preterm birth significantly contributes to the overall neonatal morbidity associated with preterm deliveries.

Nearly 50% of cases are associated with microbial invasion of the amniotic cavity followed by an inflammatory response.

Robust diagnostic tools for neonates jeopardized by infection and inflammation may thus decrease the overall neonatal morbidity substantially.

Amniotic fluid retrieved during labor retains fetal and pregnancy-related protein fingerprint and its sampling does not place any unwanted stress on women.

Using exploratory and targeted methods we analyzed proteomes of amniotic fluid sampled at the end of spontaneous preterm labor prior to delivery from women with and without infection and inflammation.

Exploratory data indicated several amniotic fluid proteins to be associated with infectious-inflammatory complications in spontaneous preterm birth.

LC-SRM analysis subsequently verified statistically significant changes in lipocalin-1 (P=0.047 and AUC = 0.67, P=0.046), glycodelin (P=0.013 and AUC = 0.73, P=0.013), and nicotinamide phosphoribosyltransferase (P=0.018 and AUC = 0.71, P=0.01).
