【摘要】:目的探討重癥急性胰腺炎(SAP)膿毒癥的發(fā)生與腸道細(xì)菌易位、炎癥及免疫抑制的關(guān)系。方法 2012年3月-2016年10月本院重癥醫(yī)學(xué)科收治的SAP患者160例,按膿毒癥診斷標(biāo)準(zhǔn)分為膿毒癥組(63例)和非膿毒癥組(97例)。采集患者胰腺周圍滲液進(jìn)行細(xì)菌培養(yǎng),同時(shí)留取尿液及血液標(biāo)本用于腸粘膜通透性、炎癥及免疫相關(guān)指標(biāo)的檢測。結(jié)果 160例SAP患者胰腺周圍滲液中共分離出225株細(xì)菌,主要為革蘭陰性菌(81.78%),包括大腸埃希菌、銅綠假單胞桿菌、產(chǎn)氣桿菌、肺炎克雷伯菌,革蘭陽性菌(18.22%)包括金黃色葡萄球菌、表皮葡萄球菌和腸球菌,膿毒癥和非膿毒癥組細(xì)菌構(gòu)成基本一致;膿毒癥組患者血清內(nèi)毒素(ET)[(0.62±0.06)EU/ml]、腫瘤壞死因子α(TNF-α)[(4.44±0.07)g/L]、白細(xì)胞介素1β(IL-1β)[(1.86±0.22)μg/L、IL-6(239.40±38.93)]、IL-8[(0.55±0.12)μg/L]水平,乳果糖與甘露醇排泄率比值(L/M)(0.54±0.08)以及外周血調(diào)節(jié)性T細(xì)胞(Treg)水平[(10.64±1.50)%]均顯著高于非膿毒癥組(P0.05),T輔助淋巴細(xì)胞1/2(Th1/Th2)值(0.84±0.34)低于非膿毒癥組(P0.05)。結(jié)論 SAP膿毒癥的發(fā)生與腸源性細(xì)菌易位、炎癥因子的過度釋放及免疫抑制等因素所導(dǎo)致的腸屏障功能受損密切相關(guān)。
[Abstract]:Objective to investigate the relationship between sepsis of severe acute pancreatitis (SAP) and intestinal bacterial translocation, inflammation and immunosuppression. Methods from March 2012 to October 2016, 160 patients with SAP were treated in our hospital. According to the diagnostic criteria of sepsis, the patients were divided into sepsis group (n = 63) and non-sepsis group (n = 97). The peripancreatic effusion was collected for bacterial culture, and urine and blood samples were collected for intestinal mucosal permeability. Results A total of 225 strains of bacteria were isolated from peripancreatic exudate of 160 patients with SAP, mainly Gram-negative bacteria, including Escherichia coli, Pseudomonas aeruginosa, Aerobacterium pneumoniae, Klebsiella pneumoniae. Gram-positive bacteria include Staphylococcus aureus, Staphylococcus epidermidis and Enterococcus, septic group and non-septic group, the bacterial composition of sepsis group is basically the same, the serum endotoxin et (0.62 鹵0.06 EUP / ml), tumor necrosis factor- 偽 (TNF- 偽) [4.44 鹵0.07g / L], IL-1 尾 [1.86 鹵0.22) 渭 g / L IL-6239.40 鹵38.93 渭 g / L] IL-8 [0.55 鹵0.12 渭 g / L] in sepsis group. The ratio of lactulose to mannitol excretion rate and the level of T cells in peripheral blood [10. 64 鹵1. 50%] were significantly higher than those in non septic patients (P 0. 05 T helper lymphocytes 1 / 2 Th1 / Th2 + 0. 84 鹵0. 34). Conclusion the occurrence of SAP sepsis is associated with the translocation of enterogenous bacteria. Excessive release of inflammatory factors and immunosuppressive factors are closely related to impaired intestinal barrier function.
