慢加急性肝衰竭防治的研究进展

慢加急性肝衰竭(ACLF)是指在慢性肝病基础之上(如病毒、酒精、药物、自身免疫性肝病等)出现的急性(通常在4周以内)肝功能失代偿表现的临床综合征,常伴随多器官功能障碍,病死率较高,同时普通治疗手段的治疗效果较差.现对ACLF的诊断标准、危险因素、内科综合治疗、人工肝支持系统、肝移植治疗以及新型冠状病毒肺炎(COVID-...     

慢加急性肝衰竭的定义、预后评估及诊治进展

慢加急性肝衰竭(ACLF)是一种在慢性肝病基础上发生肝功能急性失代偿的临床综合征,目前全球尚无统一定义标准。其显著特征是肝病进展迅速,常伴发多器官功能衰竭,短期病死率高。慢性肝病以慢性病毒性肝炎和酒精性肝病最为常见。感染、酒精、肝毒性药物等是其发生的主要诱因,但有高达40%～50%的ACLF病例没有可识别的诱发因素。早期发现并准确评估病情对ACLF患者至关重要,但目前仍缺乏早期预警并准确评估病情的理想方法。目前的治疗方法主要为器官支持和并发症的治疗,肝移植是唯一能够改善预后的治疗手段,但如何选择合适的患者以及肝移植的时机仍存在一定争议。

Stratified alpha-fetoprotein pattern accurately predicts mortality in patients with acute-on-chronic hepatitis B liver failure

Background: Alpha-fetoprotein (AFP) has been shown to predict the prognosis of liver disease in several studies. This study aimed to evaluate the prognostic value of stratified AFP in patients with acute-on-chronic hepatitis B liver failure (ACHBLF).

Methods: A total of 192 patients were included and AFP were categorized into quartiles. The prognostic value was determined for overall survival (OS) and assessed by Kaplan-Meier analysis. Univariate and multivariate Cox proportional hazard regression analyses studied the association of all independent parameters with disease prognosis.

Results: The optimal cut-off points of AFP were: (Q1) 252.3–4800.0 ng/ml, (Q2) 76.0–252.2 ng/ml, (Q3) 18.6–75.9 ng/ml, and (Q4) 0.7–18.5 ng/ml. Based on the Kaplan-Meier analysis of the OS, each AFP quartile revealed a progressively worse OS and apparent separation (log-rank P = 0.006). The second-highest quartiles of AFP (Q2) always demonstrated an extremely favorable short-term survival. Combining the lowest AFP quartiles with a serum sodium < 131mmol/L or an INR ≥ 3.3 showed a poor outcome (90-days survival of 25.0% and 11.9% respectively).

Conclusions: Stratified AFP could strengthen the predictive power for short-term survival of patients with ACHBLF. Combining AFP quartiles with low serum sodium and high INR may better predict poor outcome in ACHBLF patients.     

HBV相关慢加急性肝衰竭患者短期预后预测模型的建立与评价

目的探讨HBV相关慢加急性肝衰竭(HBV-ACLF)患者短期(12周)生存预后的预测因素,建立新型预测模型。方法收集2015年4月-2018年8月在安徽医科大学附属省立医院确诊HBV-ACLF的67例患者的临床资料,根据确诊后12周随访生存情况分为生存组(n=28)和死亡组(n=39)。收集患者临床资料,包括性别、年龄、TBil、国际标准化比值(INR)、肌酐(Cr)、血清钠、PLT、ALT、AST、Alb、血清胱抑素C(CysC),是否有急性肾损伤(AKI)。正态分布的计量资料2组间比较采用t检验,偏态分布的计量资料2组间比较采用Wilcoxon秩和检验;计数资料组间比较采用χ2检验;影响HBV-ACLF患者预后因素采用多因素logistic回归法并建立预测模型;采用受试者工作特征曲线(ROC曲线)评价预测模型,ROC曲线下面积(AUC)的比较采用DeLong法。结果死亡组患者的年龄、TBil、INR、CysC、MELD评分均高于生存组,合并AKI患者的近期生存率明显低于无AKI者(P值均<0.05)。TBil[比值比(OR)=1.013,95%可信区间(95%CI):1.003~1.024,P=0.014]、INR(OR=6.857,95%CI:1.449~32.449,P=0.015)、CysC(OR=2.826,95%CI:1.001~7.983,P=0.050)、PLT(OR=0.982,95%CI:0.964~1.000,P=0.048)是HBV-ACLF患者短期生存的独立影响因素。TBil、INR、CysC和PLT联合建立TICP模型,TICP模型的AUC(95%CI)为0.879(0.776~0.946),MELD评分的AUC(95%CI)为0.760(0.644~0.859),两者比较有差异统计学意义(Z=2.708,P=0.007)。TICP预测HBVACLF患者短期生存情况的准确度(87.05%vs 67.16%)、敏感度(84.62%vs 56.41%)、约登指数(0.70 vs 0.42)均优于MELD评分。结论TBil、INR、CysC、PLT是HBV-ACLF患者短期预后的独立影响因素,四者联合建立的TICP预测模型对患者短期生存预后具有良好的预测价值。     

Soluble mannose receptor as a predictor of prognosis of hepatitis B virus-related acute-on-chronic liver failure

BACKGROUND Hepatitis B virus-related acute-on-chronic liver failure(HBV-ACLF) is a syndrome with a high short-term mortality rate, and it is crucial to identify those patients at a high mortality risk clinically.AIM To investigate the clinical value of soluble mannose receptor(sMR) in predicting the 90-day mortality of HBV-ACLF patients.METHODS A total of 43 patients were diagnosed with HBV-ACLF between October 2017 and October 2018 at the Second Hospital of Anhui Medical University, and all of them were enrolled in this retrospective study. Their serum sMR levels were determined using an enzyme-linked immunosorbent assay. Demographic and clinical data, including gender, age, albumin level, total bilirubin(TBIL) level,international normalized ratio, HBV-DNA level, HBV serological markers,procalcitonin level, interleukin-6 level, and model for end-stage liver disease(MELD) score were accessed at the time of diagnosis of HBV-ACLF. A multivariate logistic regression analysis was used to analyze the independent risk factors for mortality.RESULTS Serum sMR level was significantly increased in HBV-ACLF patients compared with chronic hepatitis B patients and healthy controls(P 0.01). When compared with surviving patients, it was higher in those patients who succumbed to HBVACLF(P 0.05). Serum sMR level was positively correlated with MELD score(rs= 0.533, P = 0.001), HBV-DNA level(rs = 0.497, P = 0.022), and TBIL level(rs =0.894, P 0.001). Serum sMR level(odds ratio = 1.007, 95% confidence interval:1.004–1.012, P = 0.001) was an independent risk factor for the 90-day mortality inthe HBV-ACLF cases. The patients with HBV-ACLF were stratified into two groups in accordance with their serum sMR levels at the baseline(low risk: 99.84 pg/mL and high risk: ≥ 99.84 pg/mL). The 90-day mortality rates were27.3% in the low-risk group and 87.5% in the high-risk group. Furthermore, sMR level apparently improved the performance of MELD score for predicting the prognosis of patients with HBV-ACLF.CONCLUSION Serum sMR level may be a predictor of the prognosis of HBV-ACLF patients.

Score model for predicting acute-on-chronic liver failure risk in chronic hepatitis B

AIM: To establish a clinical scoring model to predict risk of acute-on-chronic liver failure(ACLF) in chronic hepatitis B(CHB) patients.METHODS: This was a retrospective study of 1457 patients hospitalized for CHB between October 2008 and October 2013 at the Beijing Ditan Hospital, Capital Medical University, China. The patients were divided into two groups: severe acute exacerbation(SAE) group(n = 382) and non-SAE group(n = 1075). The SAE group was classified as the high-risk group based on the higher incidence of ACLF in this group than in the non-SAE group(13.6% vs 0.4%). Two-thirds of SAE patients were randomly assigned to risk-model derivation and the other one-third to model validation. Univariate risk factors associated with the outcome were entered into a multivariate logistic regression model for screening independent risk factors. Each variable was assigned an integer value based on the regression coefficients, and the final score was the sum of these values in the derivation set. Model discrimination and calibration were assessed using area under the receiver operating characteristic curve and the Hosmer-Lemeshow test. RESULTS: The risk prediction scoring model includedthe following four factors: age ≥ 40 years, total bilirubin ≥ 171 μmol/L, prothrombin activity 40%-60%, and hepatitis B virus DNA 107 copies/m L. The sum risk score ranged from 0 to 7; 0-3 identified patients with lower risk of ACLF, whereas 4-7 identified patients with higher risk. The Kaplan-Meier analysis showed the cumulative risk for ACLF and ACLF-related death in the two risk groups(0-3 and 4-7 scores) of the primary cohort over 56 d, and log-rank test revealed a significant difference(2.0% vs 33.8% and 0.8% vs 9.4%, respectively; both P 0.0001). In the derivation and validation data sets, the model had good discrimination(C index = 0.857, 95% confidence interval: 0.800-0.913 and C index = 0.889, 95% confidence interval: 0.820-0.957, respectively) and calibration demonstrated by the Hosmer-Lemeshow test(χ2 = 4.516, P = 0.808 and χ2 = 1.959, P = 0.923, respectively).CONCLUSION: Using the scoring model, clinicians can easily identify patients(total score ≥ 4) at high risk of ACLF and ACLF-related death early during SAE.
