[摘要] 目的 探討肠外营养(PN)、肠内营养(EN)及益生菌对重症急性胰腺炎患者肠道细菌变化和细胞因子的影响。 方法 收集赣南医学院附属萍乡医院2017年1月至2019年12月重症急性胰腺炎患者203例,随机分为三组:肠外营养(PN)组、肠内营养(EN)组、肠内营养+益生菌(EN+益生菌)组。并评估三组APACHE Ⅱ得分、脓毒血症、多器官功能障碍综合征(MODS)发生率、死亡率、大便菌群的变化、血浆内毒素、肿瘤坏死因子α(TNF-α)、白细胞介素6(IL-6)、IL-10的水平。 结果 EN组、EN+益生菌组与PN组比较,APACHE Ⅱ评分、MODS的发生率、死亡率、粪便致病菌数、血清内毒素、TNF-α和IL-6浓度显著降低(P<0.05);粪便有益菌和血清IL-10显著升高(P<0.05)。EN+益生菌组与EN组比较,APACHE Ⅱ评分、MODS的发生率、粪便致病菌、血清内毒素、TNF-α和IL-6浓度显著降低(P<0.05);粪便有益菌和血清IL-10显著升高(P<0.05);两组死亡率比较,差异无统计学意义(P>0.05)。 结论 EN可通过改善肠道屏障功能在SAP的治疗中发挥有效作用,益生菌可与EN起协同作用,提高治疗效果。

[Abstract] Objective To explore the efficacies of parenteral nutrition (PN), enteral nutrition (EN) and probiotics on intestinal bacterial changes and cytokines in patients with severe acute pancreatitis. Methods A total of 203 patients with severe acute pancreatitis admitted to Pingxiang Hospital Affiliated to Gannan Medical University from January 2017 to December 2019 were randomLy divided into three groups, which were the PN group, the EN group and the EN combined with probiotics group. Meanwhile, the three group APACHE Ⅱ score, sepsis, MODS incidence, mortality, change of coliform, serum endotoxin, TNF-α,IL-6 and IL-10 levels were evaluated. Results Compared with the PN group, APACHE Ⅱ score, MODS incidence, mortality, fecal pathogenic bacteria, serum endotoxin, TNF-α and IL-6 concentrations in the EN group or EN combined with probiotics group decreased significantly(P<0.05), while the fecal beneficial bacteria and serum IL-10 increased significantly(P<0.05). Compared with the EN group, APACHE Ⅱ score, MODS incidence, fecal pathogenic bacteria, serum endotoxin, TNF-α and IL-6 concentrations in the EN combined with probiotics group decreased significantly, while the fecal beneficial bacteria and serum IL-10 increased significantly(P<0.05). There was no statistically significant difference of two group in mortality(P>0.05). Conclusion EN can play an effective role in the treatment of SAP by improving the intestinal barrier function, and probiotics can play a synergistic role with EN to improve the therapeutic efficacy.

重症急性胰腺炎(SAP)是常见的消化系统危重病,常引发多器官功能障碍综合征(Multiorgan dysfunction syndrome,MODS)[1],部分患者会继发胰腺坏死组织感染进入感染期,进而导致腹腔感染、肠瘘、脓毒血症、出血等一系列并发症,病死率高[2]。肠黏膜缺血、通透性增高引起肠道细菌从肠黏膜面向浆膜面、周围组织、淋巴结等处易位引起继发感染。SAP在治疗过程中过度依靠胃肠外营养引起肠道黏膜上皮营养不良而萎缩,肠黏膜屏障功能和免疫功能严重受损,产生肠道菌群易位,形成“二次打击”,加重病情。对SAP患者实施早期肠内营养(Eternal nutrition,EN)补充益生菌可有效维护肠黏膜屏障功能,降低疾病后期感染、多脏器功能衰竭的发生,改善预后[3-4]。……
