摘要:

目的 系统评价早产儿口服补充二十二碳六烯酸(DHA)和花生四烯酸(ARA)对坏死性小肠结肠炎(NEC)的影响,并阐明其关联性。 方法 检索PubMed、中国知网和万方等7个中英文数据库,收集建库至2025年10月关于早产儿口服补充DHA和ARA与NEC相关性的研究。2名研究者独立完成文献筛选与资料提取,并通过漏斗图及Egger检验评估发表偏倚。以相对危险度(RR)及95%置信区间(CI)作为效应指标,进行Meta分析。 结果 共纳入10项研究,其中6项为低偏倚风险,4项偏倚风险不确定。Meta分析,口服补充DHA和ARA对NEC发生率无明显影响(RR=1.01,95%CI:0.72~1.43,P=0.94)。亚组和敏感性分析,补充形式(DHA联合ARA补充或单独DHA补充)、剂量水平(高或低剂量),不同胎龄(胎龄≥28周或胎龄<28周),均未对NEC的发生率产生明显影响;对Bell分期≥Ⅱ级早产儿的NEC发生率无影响。 结论 早产儿口服补充DHA和ARA尚未显示对NEC发生率具有显著保护作用,其在NEC防治中的临床价值仍需进一步研究验证。

Abstract:

Objective To systematically evaluate the effect of oral supplementation of docosahexaenoic acid (DHA) and arachidonic acid (ARA) on the incidence of necrotizing enterocolitis (NEC) in the preterm infants, and to clarify the correlation. Methods Seven Chinese and English databases including PubMed, CNKI, and Wanfang were searched for studies on the association between oral DHA and ARA supplementation and NEC in the preterm infants from inception to October 2025. Two researchers independently completed literature screening and data extraction. The publication bias was assessed using funnel plots and Egger’s test. Relative risk (RR) and 95% confidence interval (CI) were used as effect indicators, and Meta analysis was performed. Results A total of 10 studies were included, including 6 studies with low risk of bias and 4 studies with unclear risk. The Meta-analysis results showed that oral DHA and ARA supplementation had no significant effect on the incidence of NEC (RR=1.01, 95%CI: 0.72-1.43, P=0.94). The subgroup and sensitivity analyses results indicated that the form of supplementation (DHA combined with ARA or DHA alone), the dose level (high or low dose), and different gestational ages of the preterm infants didn’t significantly affect the incidence of NEC; no significant effect was observed on the NEC incidence of preterm infants with Bell stage≥Ⅱ grade. Conclusion Oral supplementation of DHA and ARA in the preterm infants has not been shown to have a significant protective effect on the incidence of NEC, and its clinical value in the prevention and treatment of NEC still needs to be further verified by research.
