Prognostic factors and treatment effect of standard-volume plasma exchange for acute and acute-on-chronic liver failure: A single-center retrospective study

Patients with acute liver failure (ALF) and acute-on-chronic liver failure (ACLF) have a high risk of mortality. Few studies have reported prognostic factors for patients receiving plasma exchange (PE) for liver support. We conducted a retrospective analysis using data of 55 patients with severe ACLF (n?=?45) and ALF (n?=?10) who received standard-volume PE (1–1.5 plasma volume) in the ICU. Hepatitis B virus infection accounts for the majority of ACLF (87%) and ALF (50%) patients. PE significantly improved the levels of total bilirubin, prothrombin time and liver enzymes (P<0.05). Thirteen ACLF patients (29%) and one ALF patient (10%) underwent liver transplantation. Two ALF patients (20%) recovered spontaneously without transplantation. The overall in-hospital survival rates for ACLF and ALF patients were 24% and 30%, and the transplant-free survival rates were 0% and 20%, respectively. For the 14 transplanted patients, the one-year survival rate was 86%. Multivariate analysis showed that pre-PE hemoglobin (P?=?0.008), post-PE hemoglobin (P?=?0.039), and post-PE CLIF-C ACLF scores (P?=?0.061) were independent predictors of survival in ACLF. The post-PE CLIF-C ACLF scores ≥59 were a discriminator predicting the in-hospital mortality (area under the curve?=?0.719, P?=?0.030). Cumulative survival rates differed significantly between patients with CLIF-C ACLF scores ≤ 58 and those with CLIF-C ACLF scores ≥ 59 after PE (P< 0.05). The findings suggest that PE is mainly a bridge for liver transplantation and spontaneous recovery is exceptional even in patients treated with PE. A higher improvement in the post-PE CLIF-C ACLF score is associated with a superior in-hospital survival rate.     

Ammonia predicts poor outcomes in patients with hepatitis B virus-related acute-on-chronic liver failure

BackgroundHepatic encephalopathy (HE) is a common feature of acute liver failure and has been reported to be associated with poor outcomes. Ammonia is thought to be central to the pathogenesis of HE, but its role in hepatitis B virus‐related acute‐on‐chronic liver failure (HBV‐ACLF) is unclear. The present study aimed to assess the prognostic role of ammonia level for patients with HBV‐ACLF.MethodsWe retrospectively recruited 127 patients diagnosed with HBV‐ACLF for the present study.ResultsAmmonia levels at the time of admission were higher among non‐surviving participants than in survivors. Increased ammonia level was found to be associated with severe liver disease and was identified as an independent predictor for mortality in patients with HBV‐ACLF.ConclusionsOur results suggest that high ammonia level at admission is an independent factor for predicting short‐term mortality in patients with HBV‐ACLF. Therefore, ammonia levels may represent a therapeutic target for this condition.     

RDW,NLR and RLR in predicting liver failure and prognosis in patients with hepatitis E virus infection

Background & aimsHepatitis E virus (HEV) infection contributes to substantial proportion of acute liver injury. This study aims to evaluate the ability of red cell distribution width (RDW), neutrophil to lymphocyte ratio (NLR) and RDW to lymphocyte ratio (RLR) in predicating the development of liver failure following HEV infection and the prognosis.Methods93 healthy controls, 152 current/recent HEV infected patients without liver failure (HEV-non-LF) and 62 HEV patients who developed liver failure (HEV-LF) were enrolled in the study. The clinical and laboratory characteristics on admission, including RDW, neutrophil, lymphocyte, were recorded. Additional 24 HEV-LF patients and 24 HEV-non-LF patients were enrolled to validate the diagnostic efficacy of the three parameters.ResultsRDW, NLR and RLR were higher in HEV patients developing liver failure, compared with HEV-non-LF patients. Positive associations of increased RDW, RLR, NLR and incidence of liver failure were found. The AUC of RLR for predicting HEV-related liver failure was 0.74, superior to NLR and RDW. The sensitivity and specificity of RLR for predicting HEV-related liver failure were 0.74 and 0.65 respectively, superior to NLR (0.66, 0.70) and RDW (0.58, 0.67). However, no correlation between any of the three parameters and prognosis of HEV-LF was found. In addition, the three parameters were correlated with ALB, TBIL and Child-Pugh score in HEV-non-LF subjects, other than in HEV-LF patients.ConclusionRDW, NLR and RLR are capable to predicate the development of liver failure in HEV patients, among which RLR showed the best sensitivity and specificity. These routinely available parameters shall be considered as new preliminarily diagnostic markers for fulminant hepatic damage in HEV patients.     

Hyponatremia influences the outcome of patients with acute-on-chronic liver failure: an analysis of the CANONIC study

Introduction

Hyponatremia is a marker of poor prognosis in patients with cirrhosis. This analysis aimed to assess if hyponatremia also has prognostic value in patients with acute-on-chronic liver failure (ACLF), a syndrome characterized by acute decompensation of cirrhosis, organ failure(s) and high short-term mortality.

Methods

We performed an analysis of the Chronic Liver Failure Consortium CANONIC database in 1,341 consecutive patients admitted to 29 European centers with acute decompensation of cirrhosis (including ascites, gastrointestinal bleeding, hepatic encephalopathy, or bacterial infections, or any combination of these), both with and without associated ACLF (301 and 1,040 respectively).

Results

Of the 301 patients with ACLF, 24.3% had hyponatremia at inclusion compared to 12.3% of 1,040 patients without ACLF (P <0.001). Model for end-stage liver disease, Child-Pugh and chronic liver failure-SOFA scores were significantly higher in patients with ACLF and hyponatremia compared to those without hyponatremia. The presence of hyponatremia (at inclusion or during hospitalization) was a predictive factor of survival both in patients with and without ACLF. The presence of hyponatremia and ACLF was found to have an independent effect on 90-day survival after adjusting for the potential confounders. Hyponatremia in non-ACLF patients nearly doubled the risk (hazard ratio (HR) 1.81 (1.33 to 2.47)) of dying at 90 days. However, when considering patients with both factors (ACLF and hyponatremia) the relative risk of dying at 90 days was significantly higher (HR 6.85 (3.85 to 12.19) than for patients without both factors. Patients with hyponatremia and ACLF had a three-month transplant-free survival of only 35.8% compared to 58.7% in those with ACLF without hyponatremia (P <0.001).

Conclusions

The presence of hyponatremia is an independent predictive factor of survival in patients with ACLF. In cirrhosis, outcome of patients with ACLF is dependent on its association with hyponatremia.

BACKGROUND Acute-on-chronic liver failure(ACLF),which includes hepatic and multiple extrahepatic organ failure,is a severe emergency condition that has high mortality.ACLF can rapidly progress and requires an urgent assessment of condition and referral for liver transplantation.Bacterial infections(BIs)trigger ACLF and play pivotal roles in the deterioration of clinical course.AIM To investigate the clinical characteristics and 28-d outcomes of first BIs either at admission or during hospitalization in patients with hepatitis B virus(HBV)-ACLF as defined by the Chinese Group on the Study of Severe Hepatitis B(COSSH).METHODS A total of 159 patients with HBV-ACLF and 40 patients with acute decompensation of HBV-related chronic liver disease combined with first BIs were selected for a retrospective analysis between October 2014 and March 2016.The characteristics of BIs,the 28-d transplant-free survival rates,and the independent predictors of the 28-d outcomes were evaluated.RESULTS A total of 194 episodes of BIs occurred in 159 patients with HBV-ACLF.Among the episodes,13.4%were community-acquired,46.4%were healthcare-associated,and 40.2%belonged to nosocomial BIs.Pneumonia(40.7%),spontaneous bacterial peritonitis(SBP)(34.5%),and bloodstream infection(BSI)(13.4%)were the most prevalent.As the ACLF grade increased,the incidence of SBP showed a downward trend(P=0.021).Sixty-one strains of bacteria,including 83.6%Gramnegative bacteria and 29.5%multidrug-resistant organisms,were cultivated from 50 patients with ACLF.Escherichia coli(44.3%)and Klebsiella pneumoniae(23.0%)were the most common bacteria.As the ACLF grade increased,the 28-d transplant-free survival rates showed a downward trend(ACLF-1,55.7%;ACLF-2,29.3%;ACLF-3,5.4%;P<0.001).The independent predictors of the 28-d outcomes of patients with HBV-ACLF were COSSH-ACLF score(hazard ratio[HR]=1.371),acute kidney injury(HR=2.187),BSI(HR=2.339),prothrombin activity(HR=0.967),and invasive catheterization(HR=2.173).CONCLUSION For patients with HBV-ACLF combined with first BIs,pneumonia is the most common form,and the incidence of SBP decreases with increasing ACLF grade.COSSH-ACLF score,acute kidney injury,BSI,prothrombin activity,and invasive catheterization are the independent predictors of 28-d outcomes.     

中性粒细胞/淋巴细胞比值对多发性骨髓瘤患者的预后评估价值

目的探讨外周血中性粒细胞/淋巴细胞比值(NLR)在多发性骨髓瘤(MM)患者预后中的价值。方法回顾性分析87例初诊MM患者和100例体检健康者临床资料,将MM患者以NLR平均值为临界值分为低NLR组(NLR<2.68)和高NLR组(NLR≥2.68),分析2组性别、年龄、国际分期体系(ISS)、总体生存期、实验室检查结果等资料的差异,通过Kaplan-Meier法和Cox比例风险回归模型做单因素和多因素分析,确定影响MM患者的预后因素。结果MM组的NLR值明显高于健康对照组(t=2.21,P<0.05)。与低NLR组比较,高NLR组血清β2-微球蛋白(β2-MG)、钙、肌酐水平偏高,差异有统计学意义(P<0.05)。高NLR组较低NLR组总体生存期短、5年生存率低。单因素分析和多因素分析结果显示,NLR≥2.68,β2-MG升高是MM预后不良的危险因素及独立危险因素(P<0.05)。结论NLR是MM患者预后判断的1个独立危险因素,高水平NLR患者的总体生存期短,但需大样本资料证实。
