    摘要:

    目的 探究肝硬化食管胃底静脉曲张破裂出血患者microRNA-183-5p(miR-183-5p)水平与经颈静脉肝内门腔静脉分流术(TIPS)后再出血的关系。方法 前瞻性选取2017年2月—2020年10月在西安交通大学医学院附属三二〇一医院接受TIPS治疗的食管胃底静脉曲张破裂出血患者178例作为研究对象。根据随访过程中是否再出血将患者分为再出血组和未再出血组。采用实时荧光定量聚合酶链反应检测患者TIPS前(T1)、TIPS后24 h(T2)和TIPS后7 d(T3)的miR-183-5p水平。随访患者TIPS后再出血情况,分析miR-183-5p与TIPS后再出血的关系。结果 两组患者性别、年龄、肝硬化病因、Child-Pugh分级、血小板计数、凝血酶原时间和国际标准化比率比较,差异均无统计学意义(P >0.05)。再出血组的白蛋白、血钠和血钙水平均低于未再出血组(P <0.05),门静脉内径大于未再出血组,重度食管静脉曲张占比高于未再出血组(P <0.05)。两组患者T1、T2、T3的miR-183-5p水平比较,经重复测量设计的方差分析,结果 ①不同时间点miR-183-5p有差异(P <0.05);②两组患者miR-183-5p有差异(P <0.05);③两组患者miR-183-5p变化趋势有差异(P <0.05)。T1-miR-183-5p的曲线下面积和敏感性最高,分别为0.827(95% CI:0.768,0.886)和74.55%(95% CI:61.00,85.30),T3时miR-183-5p的特异性最高,为88.62%(95% CI:81.60,93.60)。一般多因素Logistic回归分析结果显示:血钠> 136.62 mmoL/L[O^R=0.177(95% CI:0.073,0.429)]、血钙> 2.07 mmoL/L[O^R=0.386(95% CI:0.160,0.928)]和T1时miR-183-5p> 1.19[O^R=0.079(95% CI:0.029,0.216)]是肝硬化食管胃底静脉曲张破裂出血患者TIPS后发生再出血的保护因素(P <0.05),门静脉内径> 1.30 cm[O^R=3.094(95% CI:1.290,7.421)]和重度食管静脉曲张[O^R=8.342(95% CI:2.086,33.367)]是肝硬化食管胃底静脉曲张破裂出血患者TIPS后发生再出血的危险因素(P <0.05)。模型A的C-index为0.771,模型B的C-index为0.867。模型A的平均绝对误差值为0.025,模型B的平均绝对误差值为0.028;模型B预测肝硬化食管胃底静脉曲张破裂出血患者TIPS后发生再出血的净收益高于模型A。结论 肝硬化食管胃底静脉曲张破裂出血患者TIPS前miR-183-5p水平高,则发生再出血的风险低。基于miR-183-5p构建的模型B对预测肝硬化食管胃底静脉曲张破裂出血患者TIPS后发生再出血有一定价值。

    Abstract:

    Objective To investigate the relationship between microRNA-183-5p (miR-183-5p) levels and rebleeding after transjugular intrahepatic portosystemic shunt (TIPS) in cirrhosis patients with esophageal and gastric variceal bleeding.Methods A total of 178 cirrhosis patients with esophageal and gastric variceal bleeding treated with TIPS in the 3201 Hospital Affiliated to Xi’an Jiaotong University Health Science Center from February 2017 to October 2020 were prospectively selected. The patients were then divided into rebleeding group and non-rebleeding group. The levels of miR-183-5p prior to TIPS (T1), 24 h after TIPS (T2) and 7 days after TIPS (T3) were measured by quantitative real-time polymerase chain reaction (qRT-PCR). The occurrence of rebleeding after TIPS was followed up and the relationship between miR-183-5p and the occurrence of rebleeding after TIPS was analyzed.Results There was no difference in the gender, age, the cause of cirrhosis, the distribution of Child-Pugh classification, the platelet count, prothrombin time, and the international normalized ratio between the two groups. The levels of albumin, blood sodium and blood calcium in the rebleeding group were lower than those in the non-rebleeding group (P < 0.05). The inner diameter of portal veins and the frequency of severe esophageal varices in the rebleeding group were higher than those in the non-rebleeding group (P < 0.05). The levels of miR-183-5p at T1, T2, and T3 were compared between the two groups, and the repeated-measures analysis of variance demonstrated that the levels of miR-183-5p were different among the time points (P < 0.05) and between the groups (P < 0.05). The change trends of miR-183-5p levels were also different between the two groups (P < 0.05). The area under the receiver operating characteristic (ROC) curve [0.827 (95% CI: 0.768, 0.886) ] and the sensitivity [74.55% (95% CI: 61.00, 85.30) ] of the miR-183-5p level at T1, and the specificity of the miR-183-5p level at T3 [88.62% (95% CI: 81.60, 93.60) ], were the highest for determining the occurrence of rebleeding after TIPS in cirrhosis patients with esophageal and gastric variceal bleeding (P < 0.05). The multivariable Logistic regression analysis revealed that blood sodium > 136.62 mmol/L [O^R = 0.177 (95% CI: 0.073, 0.429)], blood calcium > 2.07 mmol/L [O^R = 0.386 (95% CI: 0.160, 0.928)] and the miR-183-5p level at T1 > 1.19 [O^R = 0.079 (95% CI: 0.029, 0.216) ] were independent protective factors for rebleeding after TIPS in cirrhosis patients with esophageal and gastric variceal bleeding (P < 0.05), and that the inner diameter of portal veins > 1.30 cm [O^R = 3.094 (95% CI: 1.290, 7.421) ] and severe esophageal varices [O^R = 8.342 (95% CI: 2.086, 33.367) ] were independent risk factors for rebleeding after TIPS in cirrhosis patients with esophageal and gastric variceal bleeding (P < 0.05). The concordance index (C-index) of model A (including blood sodium, blood calcium, inner diameter of portal veins and severity of esophageal varices) was 0.771, and the mean absolute error of model A was 0.025. The C-index of model B (including blood sodium, blood calcium, inner diameter of portal veins, severity of esophageal varices and the miR-183-5p level at T1) was 0.867, and the mean absolute error of model B was 0.028. The net benefit of model B to determine the occurrence of rebleeding after TIPS in cirrhosis patients with esophageal and gastric variceal bleeding was higher than that of model A.Conclusions High miR-183-5p levels before TIPS in cirrhosis patients with esophageal and gastric variceal bleeding suggest a low risk of rebleeding. The prediction model established based on the level of miR-183-5p is valuable in determining whether rebleeding occurs after TIPS in cirrhosis patients with esophageal and gastric variceal bleeding.
