Predictive factors for 28-day mortality in acute-on-chronic liver failure patients admitted to the intensive care unit

BackgroundAcute-on-chronic liver failure (ACLF) is an entity comprising an acute deterioration of liver function in cirrhotic patients, associated with organ failure(s) and high short-term mortality. We aimed to identify predictive factors for short-term mortality in patients admitted with ACLF that may benefit most from liver transplantation.MethodsRetrospective analysis of patients admitted in ACLF to a tertiary intensive care unit between 2013 and 2017 was performed. The EASL-CLIF acute-on-chronic liver failure in cirrhosis (CANONIC) criteria were used to define ACLF grade. Multivariable analysis using 28-day mortality as an end-point was performed, including severity-of-disease scores and clinical parameters.ResultsSeventy-seven patients were admitted in ACLF over the study period. The commonest aetiology of liver disease was alcohol related 52/77(68%) and the commonest precipitant of ACLF was variceal haemorrhage 38/77(49%). Overall 28-day mortality was 42/77(55%) [ACLF-(grade)1:3/42(7%); ACLF-2:10/42(24%); and, ACLF-3:29/42(69%);p = 0.002]. On multivariable analysis MELD ≥ 26 [odds ratio(OR) = 11.559; 95% confidence interval(CI):2.820–47.382;p = 0.001], ACLF-3 (OR = 3.287; 95%CI:1.047–10.325;p = 0.042) at admission and requirement for renal replacement therapy (OR = 5.348; 95%CI:1.385–20.645;p = 0.015) were independently associated with 28-day mortality.ConclusionPatients admitted with ACLF to intensive care have a high mortality rate. Defined early thresholds at admission can identify patients at the highest risk that may benefit most from liver transplantation.     

High levels of serum interleukin-6 increase mortality of hepatitis B virus-associated acute-on-chronic liver failure

BACKGROUND Patients with hepatitis B virus-associated acute-on-chronic liver failure(HBVACLF) present a complex and poor prognosis.Systemic inflammation plays an important role in its pathogenesis,and interleukin-6(IL-6) as a pro-inflammatory cytokine is related with severe liver impairment and also plays a role in promoting liver regeneration.Whether serum IL-6 influences HBV-ACLF prognosis has not been studied.AIM To determine the impact of serum IL-6 on outcome of patients with HBV-ACLF.METHODS We performed a retrospective study of 412 HBV-ACLF patients.The findings were analyzed with regard to mortality and the serum IL-6 level at baseline,as well as dynamic changes of serum IL-6 within 4 wk.RESULTS The serum IL-6 level was associated with mortality.Within 4 wk,deceased patients had significantly higher levels of IL-6 at baseline than surviving patients [17.9(7.3-57.6) vs 10.4(4.7-22.3),P = 0.011].Patients with high IL-6 levels( 11.8 pg/m L) had a higher mortality within 4 wk than those with low IL-6 levels(≤ 11.8 pg/m L)(24.2% vs 13.2%,P = 0.004).The odds ratios calculated using univariate and multivariate logistic regression were 2.10(95% confidence interval [CI]:1.26-3.51,P = 0.005) and 2.11(95%CI:1.15-3.90,P = 0.017),respectively.The mortality between weeks 5 and 8 in patients with high IL-6 levels at 4 wk was 15.0%,which was significantly higher than the 6.6% mortality rate in patients with low IL-6 levels at 4 wk(hazard ratio = 2.39,95%CI:1.05-5.41,P = 0.037).The mortality was 5.0% in patients with high IL-6 levels at baseline and low IL-6 levels at 4 wk,7.5% in patients with low IL-6 levels both at baseline and at 4 wk,11.5% in patients with low IL-6 levels at baseline and high IL-6 levels at 4 wk,and 16.7% in patients with high IL-6 levels both at baseline and at 4 wk.The increasing trend of the mortality rate with the dynamic changes of IL-6 was significant(P for trend = 0.023).CONCLUSION A high level of serum IL-6 is an independent risk factor for mortality in patients with HBV-ACLF.Furthermore,a sustained high level or dynamic elevated level of serum IL-6 indicates a higher mortality.

Assessment of scoring systems for acute-on-chronic liver failure at predicting short-term mortality in patients with alcoholic hepatitis

AIMTo assess the performance of proposed scores specific for acute-on-chronic liver failure in predicting short-term mortality among patients with alcoholic hepatitis.METHODSWe retrospectively collected data from 264 patients with clinically diagnosed alcoholic hepatitis from January to December 2013 at 21 academic hospitals in Korea. The performance for predicting short-term mortality was calculated for Chronic Liver Failure-Sequential Organ Failure Assessment (CLIF-SOFA), CLIF Consortium Organ Failure score (CLIF-C OFs), Maddrey’s discriminant function (DF), age, bilirubin, international normalized ratio and creatinine score (ABIC), Glasgow Alcoholic Hepatitis Score (GAHS), model for end-stage liver disease (MELD), and MELD-Na.RESULTSOf 264 patients, 32 (12%) patients died within 28 d. The area under receiver operating characteristic curve of CLIF-SOFA, CLIF-C OFs, DF, ABIC, GAHS, MELD, and MELD-Na was 0.86 (0.81-0.90), 0.89 (0.84-0.92), 0.79 (0.74-0.84), 0.78 (0.72-0.83), 0.81 (0.76-0.86), 0.83 (0.78-0.88), and 0.83 (0.78-0.88), respectively, for 28-d mortality. The performance of CLIF-SOFA had no statistically significant differences for 28-d mortality. The performance of CLIF-C OFs was superior to that of DF, ABIC, and GAHS, while comparable to that of MELD and MELD-Na in predicting 28-d mortality. A CLIF-SOFA score of 8 had 78.1% sensitivity and 79.7% specificity, and CLIF-C OFs of 10 had 68.8% sensitivity and 91.4% specificity for predicting 28-d mortality.CONCLUSIONCLIF-SOFA and CLIF-C OF scores performed well, with comparable predictive ability for short-term mortality compared to the commonly used scoring systems in patients with alcoholic hepatitis.

Background: Hepatitis B virus(HBV)-associated acute-on-chronic liver failure(HBV-ACLF) is a lifethreatening condition and its exact pathophysiology and progression remain unclear. The present study aimed to assess the role of serum mi RNAs in the evaluation of HBV-ACLF and to develop a model to predict the outcomes for ACLF.Methods: Serum was collected from 41 chronic hepatitis B and 55 HBV-ACLF patients in addition to30 chronic asymptomatic HBV carriers as controls. The mi RNAs expressions were measured by real-time quantitative PCR(q-PCR). Statistical analyses were conducted to assess the ability of differentially expressed mi RNAs and other prognostic factors in identifying ACLF prognosis and to develop a new predictive model.Results: Real-time q-PCR indicated that serum miR-146 a-5 p, mi R-122-3 p and mi R-328-3 p levels were significantly upregulated in ACLF patients compared to chronic hepatitis B and chronic asymptomatic HBV carriers patients. In addition, multivariate regression analyses indicated that Na+, INR, gastrointestinal bleeding and mi R-122-3 p are all independent factors that are reliable and sensitive to the prognosis of HBV-ACLF. Therefore, we developed a new model for the prediction of HBV-ACLF disease state: Y = 0.402 × Na+-1.72 × INR-4.963 × gastrointestinal bleeding(Yes = 0; No = 1)-0.278 ×(mi R-122-3 p) + 50.449. The predictive accuracy of the model was 95.3% and the area under the receiver operating characteristic curve(AUROC) was 0.847.Conclusions: Expression levels of these mi RNAs(miR-146 a-5 p, mi R-122-3 p and mi R-328-3 p) positively correlate with the severity of liver inflammation in patients with ACLF and may be useful to predict HBV-ACLF severity.     

Nomogram prediction of individual prognosis of patients with acute-on-chronic hepatitis B liver failure

Background

The current definitions and etiologies of acute-on-chronic liver failure (ACLF) are clearly very different between East and West.

HBV相关慢加急性肝衰竭患者预后及其影响因素分析*

目的 探讨影响乙型肝炎相关性慢加急性肝衰竭（ACLF）患者预后的因素。方法 2014年5月~2017年5月我院诊治的ACLF患者120例,给予内科综合治疗和人工肝治疗,回顾性分析其临床资料,应用二元多因素Logistic回归分析影响预后的因素。结果 经过3~6个月治疗,本组患者生存52例（43.3%）,死亡68例（56.7%）;两组患者性别、发病前病程、长期抗病毒和是否接受人工肝治疗等方面无显著性差异（P>0.05）,但生存组年龄≥50岁的比例和并发症发生率分别为40.4%和46.1%,均显著低于死亡组的61.8%和79.4%（P<0.05）;两组血清PAB、TBA、BUN、Cr和HBV DNA水平差异无显著性统计学意义（P>0.05）,但生存组患者血清TBIL和PT水平显著低于死亡组（P<0.05）,血清Alb、CHE、TC和AFP水平显著高于死亡组（P<0.05）;生存组肝性脑病、肝肾综合征、电解质紊乱和多种并发症发生率分别为7.7%、1.9%、15.4%和11.5%,显著低于死亡组的45.6%、14.7%、39.7%和26.5%（P<0.05）,而两组上消化道出血和自发性细菌性腹膜炎发生率比较,无显著性差异（P>0.05）;将血清TBIL、Alb、CHE、PT、TC、AFP、年龄和并发症作为自变量,预后结果作为应变量,经二元多因素Logistic回归分析发现,年龄、PT、肝性脑病、电解质紊乱和并发症发生是HBV相关的ACLF患者预后的独立影响因素。结论 了解影响乙型肝炎导致的ACLF患者预后的因素,做到早诊断,早治疗,把好可能导致死亡因素的治疗关,积极防治各种并发症,才能提高救治ACLF患者的成功率。
