Abstract:
Objective To study the changes of serum interleukin-8 (IL-8) and interleukin-10 (IL-10) in preterm infants delivered from mothers with chorioamnionitis (CA) and the possible effects on bronchopuhmonary dysplasia (BPD) and brain injury of preterm infants.Method From October 2014 to October 2015,clinical data from mothers without clinical manifestations of CA giving birth to a preterm baby (gestational age:26 to 33 weeks) were collected in Changzhou Maternal and Child Health Hospital and Suzhou Municipal Hospital.The infants were assigned to CA group and non-CA group according to their mother's placenta pathology.The levels of serum IL-8 and IL-10 were measured using enzyme-linked immunosorbent assay (ELISA) on day 1 and day 7,while the levels of WBC,CRP and PCT were measured at birth.The incidences of BPD and brain injury were also reviewed.Result A total of 67 preterm infants were included,with 51 in the CA group and 16 non-CA group.The levels of IL-8 were significantly higher in the CA group than the non-CA group on both day 1 and day 7 [(21.6 ±9.7) ng/L vs.(7.3 ±2.3) ng/L,(26.6 ± 12.9) ng/L vs.(7.3 ± 2.1) ng/L].The IL-10 levels were significantly lower on day 1 [(1.92±0.17) ng/Lvs.(2.04±0.18) ng/L] and higher on day 7 [(2.42±0.60) ng/L vs.(2.03 ±0.18) ng/L] in the CA group.Significant differences existed on the incidences of BPD (54.9％ vs.25.0％) and brain injury (74.5％ vs.43.8％) between the two groups (P ＜ 0.05).The levels of CRP and PCT were higher in CA group (P ＜ 0.05) and the WBC was similar between the two groups (P ＞ 0.05).In CA group,on both day 1 and day 7,infants with BPD had similar IL-8 and IL-10 levels comparing with infants without BPD(P ＞ 0.05),also were infants with brain injury comparing with infants without brain injury.Conclusion Chorioamnionitis in pregnant women may affect serum cytokines levels in premature infants and lead to high incidences of BPD and brain injury.
