摘要:

目的 探讨组织学绒毛膜羊膜炎(HCA)对胎龄小于34周早产儿临床结局的影响。方法 回顾性收集2019年1月—2022年12月青岛市妇女儿童医院住院的497例胎龄<34周早产儿及孕母资料。根据胎盘病理是否诊断为HCA分为HCA组(257例)及对照组(240例)。采用倾向性评分匹配方法进行1︰1匹配,将胎龄、出生体质量、性别、剖宫产、妊娠期糖尿病、妊娠期高血压、胎盘早剥、胎膜早破、产前糖皮质激素及辅助生殖等10项指标进行匹配。比较2组早产儿主要并发症及存活率的差异。结果 156对早产儿匹配成功。匹配前HCA组早发败血症(EOS)和支气管肺发育不良(BPD)发生率显著高于对照组(26.1% vs. 7.5%,45.1% vs. 25.8%,P<0.01)。匹配后HCA组EOS发生率显著高于对照组(24.4% vs. 7.7%,P<0.01),新生儿呼吸窘迫综合征(NRDS)发生率显著低于对照组(34.0% vs. 46.8%,P<0.05)。匹配前后2组早产儿存活率及其他并发症发生率差异无统计学意义(P>0.05)。结论 经倾向性评分匹配后,暴露于HCA的早产儿合并EOS风险更高,但NRDS的发病风险降低。HCA对早产儿的存活率及其他并发症无显著影响。

Abstract:

Objective To explore the effect of histologic chorioamnionitis (HCA) on clinical outcomes of preterm infants with a gestational age <34 weeks. Methods This retrospective study enrolled 497 cases of premature infants with a gestational age <34 weeks and their mothers who were hospitalized in the Qingdao Women and Children's Hospital from January 2019 to December 2022. According to whether the pathology of placenta was diagnosed as HCA or not, patients were divided into the HCA group (257 cases) and the control group (240 cases). The propensity score matching analysis was performed at a ratio of 1︰1. Ten items were matched, including gestational age, birth weight, gender, cesarean section, gestational diabetes mellitus, gestational hypertension, placental abruption, premature rupture of membranes, use of antenatal glucocorticoids and assisted reproductive technology. The differences of major complications and survival rate were compared between the two groups. Results A total of 156 pairs premature infants were successfully matched. Before matching, the incidences of early-onset sepsis (EOS) and bronchopulmonary dysplasia (BPD) were higher in the HCA group than those of the control group (26.1% vs. 7.5%, 45.1% vs. 25.8%, P<0.01). The incidence of EOS was higher in the HCA group than that of the control group after matching (24.4% vs. 7.7%, P<0.01), and the incidence of neonatal respiratory distress syndrome (NRDS) was significantly lower in the HCA group than that in the control group after matching (34.0% vs. 46.8%, P<0.05). There were no significant differences in survival rate and the incidences of other complications between the two groups before and after matching (P > 0.05). Conclusion Preterm infants exposed to HCA have a higher risk of EOS and a lower risk of NRDS after propensity score matching. HCA has no significant effect on survival rate and other complications of premature infants.
