Abstract		Background: Peri-intraventricular hemorrhage (P/IVH) is a common neonatal morbidity among premature infants. The aim of the study was to examine the association between placental and/or fetal inflammation and the onset of P/IVH in premature infants. Methods: A prospective study included 125 infants with gestational age 23-29 weeks. Placentas were examined for the presence of chorioamnionitis and funisitis, cord blood was sampled for the measurement of cytokines (IL-6 and IL-8). Fetal inflammation was defined as levels of IL-6 higher than 7.6 pg/ml. P/IVH was defined as early if diagnosed within the 1st day after birth; thereafter P/IVH was defined as late. Results: Adjusted for the influence of gestational age, early-onset sepsis (OR 3.2, p = 0.045) and no or incomplete antenatal steroid course (OR 6.0, p = 0.001) significantly predicted early P/IVH. Funisitis (OR 1.6, p = 0.06) and fetal inflammation (OR 2.6, p = 0.06) were only partially associated with early hemorrhage. Contrary to that, respiratory distress syndrome (OR 3.4, p = 0.04), mechanical ventilation (OR 5.9, p = 0.008), low blood pressure (OR 3.5, p = 0.02), and vasopressors (OR 5.7, p = 0.002) were associated with late P/IVH. In multivariate analysis no or incomplete steroid course remained independent predictors for early and use of vasopressors for late P/IVH. The interaction of fetal inflammation and vaginal delivery with no or incomplete steroid course increased the risk of early P/IVH. Conclusions: These results indicate different risk factors for early and late P/IVH. Neither funisitis nor fetal inflammation independently predicts the onset of P/IVH. However, the interaction of fetal inflammation and vaginal delivery with no or incomplete antenatal steroid course increase the risk of early but not also late P/IVH.
