- 摘要:
- 目的 探讨儿童肝移植围手术期肠黏膜屏障功能受损与耐碳青霉烯类肠杆菌(carbapenem-resistant enterobacteria,CRE)定植的相关性,以及术后肠黏膜损伤修复的一般规律。方法 本研究为回顾性研究,以2022年11月1日至2022年12月31日在天津市第一中心医院行肝移植术的40例胆道闭锁婴幼儿作为研究对象,根据肛拭子检测结果将患儿分为CRE定植组和无CRE定植组。分别于术前24 h、术后24 h、术后7 d抽取静脉血检测D-乳酸及二胺氧化酶。比较两组患儿术后D-乳酸及二胺氧化酶的差异及变化,初步分析肝移植术后肠黏膜损伤及修复的一般规律。结果 无论在CRE定植组还是无CRE定植组,D-乳酸及二胺氧化酶水平在术后24 h均达到峰值,CRE定植组术后24 h与术前24 h的D-乳酸、术后24 h与术后7 d的D-乳酸,无CRE定植组术后24 h与术前24 h的D-乳酸、术后24 h与术后7 d的D-乳酸,CRE定植组与无CRE定植组术后24 h的D-乳酸比较,差异均有统计学意义(P<0.05)。CRE定植组术后24 h与术前24 h的二胺氧化酶、术后24 h与术后7 d的二胺氧化酶[(0.22±0.04) U/L比(0.18±0.06) U/L],无CRE定植组术后24 h与术前24 h的二胺氧化酶、术后24 h与术后7 d的二胺氧化酶,CRE定植组与无CRE定植组术后24 h的二胺氧化酶比较,差异均有统计学意义(P<0.05)。而两组术前24 h与术后7 d的D-乳酸及二胺氧化酶水平以及两组之间术前24 h、术后7 d的D-乳酸及二胺氧化酶水平差异均无统计学意义(P>0.05)。结论 D-乳酸及二胺氧化酶作为肠黏膜损伤的敏感指标,在肝移植围手术期有相似的变化趋势,术后24 h内达到峰值;随着肠黏膜屏障功能的修复,在术后1周左右接近术前水平。有CRE定植的患儿肝移植术后肠黏膜屏障功能的损伤程度较无CRE定植的患儿更严重。
- Abstract:
- Objective To explore the correlation between intestinal mucosal barrier function impairment and rectal colonization of carbapenem-resistant enterobacteria (CRE) during pediatric liver transplantation (LT) and summarize the general rules of postoperative intestinal mucosal impairment and repairing.Methods From November 1st,2022 to December 31st,2022,40 children with biliary atresia (BA) undergoing LT were assigned into two groups of CRE colonization and non-CRE colonization according to the results of anal swabs.At 24 h pre-operation,24 h post-operation and Day 7 post-operation,venous blood samples were collected for detecting the levels of D-lactic acid and diamine oxidase (DAO).The inter-group differences and changes of D-lactic acid and DAO were compared.And general rules of intestinal mucosal impairment and repairing post-LT was preliminarily examined.Results The levels of D-lactic acid and DAO peaked at 24 h post-operation in both groups.In CRE colonization group,D-lactic acid of 24 h post-operation and 24 h pre-operation,24 h post-operation and Day 7 post-operation .In non-CRE colonization group,D-lactic acid of 24 h post-operation and 24 h pre-operation,24 h post-operation and Day 7 post-operation ; D-lactic acid of 24 h post-operation in CRE colonization and non-CRE colonization groups.The differences were statistically significant (P<0.05); In CRE colonization group,DAO of 24 h post-operation and 24 h pre-operation [(0.22±0.04) vs.(0.16±0.05) U/L],24 h post-operation and Day 7 post-operation .In non-CRE colonization group,DAO of 24 h post-operation and 24 h pre-operation [(0.17±0.01) vs. (0.13±0.02)U/L],24 h post-operation and Day 7 post-operation,DAO of 24 h post-operation in CRE colonization and non-CRE colonization groups .The differences were statistically significant (P<0.05).However,the levels of D-lactic acid and DAO at 24 h pre-operation and Day 7 post-operation had no significant differences in neither groups.The levels of D-lactic acid and DAO at 24 h pre-operation and Day 7 post-operation had no significant inter-group differences.Conclusions Intestinal mucosal injury peaked within 24 h post-LT and returned to the preoperative level within 1 week.In CRE colonization group,intestinal mucosal barrier injury was more severe than that in non-CRE colonization group.
