目的:探讨感染诱发AKI在慢加急性肝衰竭（ACLF）患者中的发生率、影响因素及预后。方法:回顾性研究2014至2016年住院治疗的516例慢加急性肝衰竭合并感染的患者。收集患者一般情况、临床特征，根据患者是否发生AKI及AKI严重程度分组，对其一般情况、实验室检查结果、并发症发生、生存情况进行对比分析。结果:HBV感染（67.8%）和酒精性肝病（20.0%）是主要病因。感染部位最常见于腹腔、肺部及血液。多因素分析显示血中性粒细胞计数、总胆红素、乳酸以及发生感染性休克是ACLF患者发生感染后诱发AKI的独立危险因素。感染后出现AKI患者28、90、360 d的累计病死率显著高于无AKI患者（51.6%和20.5%，70.2%和40.3%，73.4%和45.9%；n P值均< 0.01）。两组患者死亡主要发生在随访早期（0～28 d）和中期（29～90 d）。随访后期（91～360 d），两组患者病死率差异无统计学意义。n 结论:感染是ACLF患者发生AKI的重要诱因，基础肝病及感染严重程度与ACLF患者感染诱发AKI明显相关，感染后一旦发生AKI，患者病死率明显增高。“,”Objective:To investigate the incidence rate, influencing factors and prognosis of infection-induced acute renal injury (AKI) in patients with acute-on-chronic liver failure (ACLF).Methods:516 cases with acute-on-chronic liver failure complicated with infection that were hospitalized in our hospital during 2014 to 2016 were retrospectively studied. General conditions and clinical characteristics of the patients were collected, and grouped according to the presence or absence of incidence and severity of AKI. General conditions, laboratory results, occurrence of complications and survival were compared and analyzed.Results:The main causes were HBV infection (67.8%) and alcoholic liver disease (20.0%). The most common sites of infection were abdominal cavity, lung and blood. Multivariate analysis showed that neutrophil count, TBIL, lactate and septic shock were independent risk factors for infection-induced AKI in ACLF patients. The cumulative mortality in patients with AKI after infection at 28, 90 and 360 days was significantly higher than those without AKI (51.6% and 20.5%, 70.2% and 40.3%, 73.4% and 45.9%; n P < 0.01). In both groups, deaths had occurred mainly in the early (0 ~ 28 d) and middle (29 ~ 90 d) stage of follow-up period. In the late follow-up period (91-360 d), there was no statistically significant difference in mortality rate between the two groups.n Conclusion:Infection is an important inducing cause of AKI in ACLF patients. The underlying liver disease and the severity of infection are significantly related to the infection-induced AKI in ACLF patients, and once AKI occurs after infection, the mortality rate of the patients is significantly increased.
