The risk factors related to progression to hepatic decompensation(HD) and acute-on-chronic liver failure(ACLF) in patients with severe acute exacerbation(SAE) of chronic HBV infection remain unknown.AIM To identify risk factors related to progression to HD and ACLF in compensated patients with SAE of chronic HBV infection.METHODS The baseline characteristics of 164 patients with SAE of chronic HBV infection were retrospectively reviewed. Independent risk factors associated with progression to HD and ACLF were identified. The predictive values of our previously established prediction model in patients with acute exacerbation(AE model) and the model for end-stage liver disease(MELD) score in predicting the development of ACLF were evaluated.RESULTS Among 164 patients with SAE, 83(50.6%) had compensated liver cirrhosis(LC),43 had progression to HD without ACLF, and 29 had progression to ACLF within 28 d after admission. Independent risk factors associated with progression to HD were LC and low alanine aminotransferase. Independent risk factors for progression to ACLF were LC, high MELD score, high aspartate aminotransferase(AST) levels, and low prothrombin activity(PTA). The area under the receiver operating characteristic of the AE model [0.844, 95%confidence interval(CI): 0.779-0.896] was significantly higher than that of MELD score(0.690, 95%CI: 0.613-0.760, P < 0.05) in predicting the development of ACLF.CONCLUSION In patients with SAE of chronic HBV infection, LC is an independent risk factor for progression to both HD and ACLF. High MELD score, high AST, and low PTA are associated with progression to ACLF. The AE model is a better predictor of ACLF development in patients with SAE than MELD score.展开更多

METHODS: A retrospective study was conducted from January 1, 2011 to January 1, 2012. Forty patients with ACHBLF (mean age 44.48 ± 12.28 years, range 18-69 years), 40 patients with chronic hepatitis B (CHB) (mean age 39.45 ± 12.22 years, range 21-57 years) and 20 ageand sex-matched healthy controls (mean age 38.35 ± 11.97 years, range 28-60 years) were included in this study. Flow cytometry was used to analyze the frequency of CD163+ peripheral blood mononuclear cells (PBMCs) and surface protein expression of CD163. Real-time transcription-polymerase chain re-action was performed to assess relative CD163 mRNA levels in PBMCs. Plasma soluble CD163 (sCD163) levels were measured by enzyme-linked immunosorbent assay. Clinical variables were also recorded. Comparisons between groups were analyzed by Kruskal-Wallis H test and Mann-Whitney U test. Statistical analyses were performed using SPSS 15.0 software and a P value < 0.05 was considered statistically significant. RESULTS: Flow cytometry showed that the population of CD163+ PBMCs was significantly greater in ACHBLF patients than in CHB patients and healthy controls (47.9645% ± 17.1542%, 32.0975% ± 11.0215% vs 17.9460% ± 6.3618%, P < 0.0001). However, there were no significant differences in mean fluorescence intensity of CD163+ PBMCs within the three groups (27.4975 ± 11.3731, 25.8140 ± 10.0649 vs 20.5050 ± 6.2437, P = 0.0514). CD163 mRNA expression in ACHBLF patients was significantly increased compared with CHB patients and healthy controls (1.41 × 10 -2 ± 2.18 × 10 -2 , 5.10 × 10 -3 ± 3.61 × 10 -3 vs 37.0 × 10 -4 ± 3.55 × 10 -4 , P = 0.02). Plasma sCD163 levels in patients with ACHBLF were significantly increased compared with CHB patients and healthy controls (4706.2175 ± 1681.1096 ng/mL, 1089.7160 ± 736.8395 ng/mL vs 435.9562 ± 440.8329 ng/mL, P < 0.0001). In ACHBLF patients, plasma sCD163 levels were significantly positively associated with model for end-stage liver disease scores (r = 0.5075, P = 0.008), hepatitis B virus-DNA (r = 0.6827, P < 0.0001), and negatively associated with prothrombin activity (r = -0.3348, P = 0.0347), but had no correlation with total bilirubin (r = 0.2551, P = 0.1122). Furthermore, sCD163 was obviously elevated in non-surviving patients compared with surviving patients with ACHBLF (5344.9080 ± 1589.5199 ng/mL vs 3641.7333 ± 1264.5228 ng/mL, P = 0.0321). CONCLUSION: CD163 and sCD163 may be related to disease severity and prognosis in ACHBLF patients.展开更多

From 2009 to 2015, 236 patients diagnosed with HBV-related ACLF at our center were recruited for this 3-month followup study. Demographic data and serum lactate levels were collected from the patients. The MELD scores with or without serum lactate levels from survival and nonsurvival groups were recorded and compared.RESULTS Two hundred and thirty-six patients with HBV-ACLF were divided into two groups: survival group(S) andnon-survival group(NS). Compared with the NS group, the patients in survival the S group had a significantly lower level of serum lactate(3.11 ± 1.98 vs 4.67 ± 2.43, t = 5.43, P < 0.001) and MELD score(23.33 ± 5.42 vs 30.37 ± 6.58, t = 9.01, P = 0.023). Furthermore, serum lactate level was positively correlated with MELD score(r = 0.315, P < 0.001). Therefore, a modified MELD including serum lactate was developed by logistic regression analysis(0.314 × lactate + 0.172 × MELD-5.923). In predicting 3-month mortality using the MELD-LAC model, the patients from the S group had significantly lower baseline scores(-0.930 ± 1.34) when compared with those from the NS group(0.771 ± 1.32, t = 9.735, P < 0.001). The area under the receiver operating characteristic curve(AUROC) was 0.859 calculated by using the MELD-LAC model, which was significantly higher than that calculated by using the lactate level(0.790) or MELD alone(0.818). When the cutoff value was set at-0.4741, the sensitivity, specificity, positive predictive value and negative predictive value for predicting short-term mortality were 91.5%, 80.10%, 94.34% and 74.62%, respectively. When the MELD-LAC scores at baseline level were set at-0.5561 and 0.6879, the corresponding mortality rates within three months were 75% and 90%, respectively.CONCLUSION The short-term prognosis of HBV-related ACLF was improved by using a modified MELD including serum lactate from the present 6-year clinical study.展开更多

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.展开更多

This study was undertaken to evaluate the short-term efficacy of entecavir versus lamivudine on hepatitis B e antigen (HBeAg)-negative patients with ACLF. METHODS: The data of 182 HBeAg-negative patients with ACLF were retrospectively collected from patient profiles of the hospital. In these patients, 93 HBeAg-negative patients with ACLF were treated orally with 0.5 mg of entecavir and 89 were treated orally with 100 mg of lamivudine every day. The gender and age were matched between the two groups. Biochemical items, the model for end-stage liver disease (MELD) score, and HBV DNA level were matched at baseline between the two groups and monitored during treatment. The 3-month mortalities of the two groups were compared. RESULTS: No significant differences were found in biochemical items, MELD score, and HBV DNA level at baseline (P】0.05). HBV DNA level decreased within 3 months in both groups (P【0.05), regardless of the pretreatment MELD score. In patients with the same range of pretreatment MELD scores, treatment duration, posttreatment HBV DNA levels, percentage of HBV DNA level 【2.7 lg copies/mL, biochemical items, MELD scores and 3-month mortality were similar in the two groups (all P】0.05). Pretreatment MELD score was not related to posttreatment HBV DNA levels (P】0.05), but related to a 3-month mortality in both groups (both P【0.001).CONCLUSIONS: In HBeAg-negative patients with ACLF, the short-term efficacy of entecavir versus lamivudine was similar. The degree of pretreatment liver failure significantly affected the outcome of treatment.展开更多

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.展开更多

There is a direct relationship between HBVACLFand gastrointestinal barrier function. However, the nutritional status ofHBV-ACLF patients has been poorly studied.AIMTo investigate the nutritional risk and nutritional status of HBV-ACLF patientsand evaluated the impact of nutritional support on the gastrointestinal barrier and28-d mortality.METHODSNutritional risk screening assessment and gastrointestinal barrier biomarkers ofpatients with HBV-ACLF (n = 234) and patients in the compensatory period ofliver cirrhosis (the control group) (n = 234) were compared during the periodbetween 2016 and 2018. Changes were analyzed after nutritional support in HBVACLFpatients. Valuable biomarkers have been explored to predict 28-d death.The 28-d survival between HBV-ACLF patients with nutritional support (n = 234)or no nutritional support (2014-2016) (n = 207) was compared.RESULTSThe nutritional risk of the HBV-ACLF patients was significantly higher than thatof the control group. The nutritional intake of the patients with HBV-ACLF waslower than that of the control group. The decrease in skeletal muscle and fatcontent and the deficiency of fat intake were more obvious (P < 0.001). Thecoccus-bacillus ratio, secretory immunoglobulin A, and serum D-lactate weresignificantly increased in HBV-ACLF patients. The survival group had a lowernutritional risk, lower D-lactate, and cytokine levels (endotoxin, tumor necrosisfactor alpha, interleukin-10, and interleukin-1). Interleukin-10 may be a potentialpredictor of death in HBV-ACLF patients. The 28-d survival of the nutritionalsupport group was better than that of the non-nutritional support group (P =0.016).CONCLUSIONPatients with HBV-ACLF have insufficient nutritional intake and high nutritionalrisk, and their intestinal barrier function is impaired. Individualized and dynamicnutritional support is associated with a better prognosis of 28-d mortality in HBVACLFpatients.展开更多

文摘BACKGROUND Stromal cell derived factor-1(SDF-1)plays a pivotal role in the recruitment of stem cells to injured livers.However,the changes of SDF-l in patients with hepatitis B virus(HBV)-related acute-on-chronic liver failure(ACLF)have yet to be elucidated.AIM To study the SDF-1 changes in patients with HBV-related ACLF.METHODS 30 patients with HBV-related ACLF,27 patients with chronic hepatitis B and 20 healthy individuals are involved in our study.The SDF-l mRNA expression in liver tissue was detected by quantitative real-time polymerase chain reaction.Immunohistochemical staining was performed to illustrate the expression of SDFl,CXC receptor 4(CXCR4)and Ki67.The serum SDF-l concentrations were also detected by enzyme-linked immunosorbent assays.RESULTS The expression of SDF-1 mRNA from ACLF patients was remarkably higher than that from other patients(both P<0.05).The expression of SDF-l,CXCR4 and Ki67 from ACLF were the highest among the three groups(all P<0.01).The serum SDF-l levels in ACLF patients were significantly lower than that in other patients(both P<0.01).Moreover,in ACLF patients,the serum SDF-1 Levels were positively correlated with serum total bilirubin and international normalized ratio.In addition,the serum SDF-l levels in survival were significantly lower compared with the non-survivals(P<0.05).The area under the curve for the serum SDF-1 level in predicting 28-d mortality was 0.722(P<0.05).CONCLUSION This study provides the SDF-1 changes in patients with HBV-related ACLF.The SDF-1 Level at admission may serve as a promising prognostic marker for predicting short-term prognosis.

文摘BACKGROUND Post-hepatectomy liver failure(PHLF)is a common consequence of radical partial hepatectomy in hepatocellular carcinoma(HCC).AIMS To investigate the relationship between preoperative antiviral therapy and PHLF,as well as assess the potential efficacy of hepatitis B virus(HBV)DNA level in predicting PHLF.METHODS A retrospective study was performed involving 1301 HCC patients with HBV who underwent radical hepatectomy.Receiver operating characteristic(ROC)analysis was used to assess the capacity of HBV DNA to predict PHLF and establish the optimal cutoff value for subsequent analyses.Logistic regression analyses were performed to assess the independent risk factors of PHLF.The increase in the area under the ROC curve,categorical net reclassification improvement(NRI),and integrated discrimination improvement(IDI)were used to quantify the efficacy of HBV DNA level for predicting PHLF.The P<0.05 was considered statistically significant.RESULTS Logistic regression analyses showed that preoperative antiviral therapy was independently associated with a reduced risk of PHLF(P<0.05).HBV DNA level with an optimal cutoff value of 269 IU/mL(P<0.001)was an independent risk factor of PHLF.All the reference models by adding the variable of HBV DNA level had an improvement in area under the curve,categorical NRI,and IDI,particularly for the fibrosis-4 model,with values of 0.729(95%CI:0.705-0.754),1.382(95%CI:1.341-1.423),and 0.112(95%CI:0.110-0.114),respectively.All the above findings were statistically significant.CONCLUSION In summary,preoperative antiviral treatment can reduce the incidence of PHLF,whereas an increased preoperative HBV DNA level has a correlative relationship with an increased susceptibility to PHLF.

文摘Background:It has been demonstrated that thymosinβ4(Tβ4)could inflect the severity of acute-on-chronic hepatitis B liver failure(ACHBLF),but the relationship between its methylation status and the prognosis of liver failure is not clear.This study aimed to determine Tβ4 promoter methylation status in patients with ACHBLF and to evaluate its prognostic value.Methods:The study recruited 115 patients with ACHBLF,80 with acute-on-chronic hepatitis B pre-liver failure(pre-ACHBLF),and 86 with chronic hepatitis B(CHB).In addition,there were 36 healthy controls(HCs)from the Department of Hepatology,Qilu Hospital of Shandong University.The 115 patients with ACHBLF were divided into three subgroups:33 with early stage ACHBLF(E-ACHBLF),42 with mid-stage ACHBLF(M-ACHBLF),and 40 with advanced stage ACHBLF(A-ACHBLF).Tβ4 promoter methylation status in peripheral blood mononuclear cells(PBMCs)was measured by methylation-specific polymerase chain reaction,and mRNA was detected by quantitative real-time polymerase chain reaction.Results:Methylation frequency of Tβ4 was significantly higher in patients with ACHBLF than in those with pre-ACHBLF,CHB or HCs.However,expression of Tβ4 mRNA showed the opposite trend.In patients with ACHBLF,Tβ4 promoter methylation status correlated negatively with mRNA levels.The 3-month mortality of ACHBLF in the methylated group was significantly higher than that in the unmethylated group.Also,Tβ4 promoter methylation frequency was lower in survivors than in non-survivors.When used to predict the 1-,2-,and 3-month incidence of ACHBLF,Tβ4 methylation status was better than the model for end-stage liver disease(MELD)score.The predictive value of Tβ4 methylation was higher than that of MELD score for the mortality of patients with E-ACHBLF and M-ACHBLF,but not for A-ACHBLF.Conclusions:Tβ4 methylation might be an important early marker for predicting disease incidence and prognosis in patients with ACHBLF.

文摘BACKGROUND The lymphocyte-to-white blood cell ratio(LWR)is a blood marker of the systemic inflammatory response.The prognostic value of LWR in patients with hepatitis B virus-associated acute-on-chronic liver failure(HBV-ACLF)remains unclear.AIM To explore whether LWR could stratify the risk of poor outcomes in HBV-ACLF patients.METHODS This study was conducted by recruiting 330 patients with HBV-ACLF at the Department of Gastroenterology in a large tertiary hospital.Patients were divided into survivor and non-survivor groups according to their 28-d prognosis.The independent risk factors for 28-d mortality were calculated by univariate and multivariate Cox regression analyses.Patients were divided into low-and high-LWR groups according to the cutoff values.Kaplan-Meier analysis was performed according to the level of LWR.RESULTS During the 28-d follow-up time,135 patients died,and the mortality rate was 40.90%.The LWR level in non-surviving patients was significantly decreased compared to that in surviving patients.A lower LWR level was an independent risk factor for poor 28-d outcomes(hazard ratio=0.052,95%confidence interval:0.005-0.535).The LWR level was significantly negatively correlated with the Child-Turcotte-Pugh,model for end-stage liver disease,and Chinese Group on the Study of Severe Hepatitis B-ACLF II scores.In addition,the 28-d mortality was higher for patients with LWR<0.11 than for those with LWR≥0.11.CONCLUSION LWR may serve as a simple and useful tool for stratifying the risk of poor 28-d outcomes in HBVACLF patients.

文摘BACKGROUND There have been no reports of acute-on-chronic liver failure(ACLF)during treatment of chronic hepatitis C(CHC)with direct-acting antivirals(DAAs).CASE SUMMARY We report a 50-year-old male patient with CHC.The patient sought medical attention from the Department of Infectious Diseases at our hospital due to severe yellowing of the skin and sclera,which developed 3 mo previously and attended two consecutive hospitals without finding the cause of liver damage.It was not until 1 mo ago that he was diagnosed with CHC at our hospital.After discharge,he was treated with DAAs.During treatment,ACLF occurred,and timely measures such as liver protection,enzyme lowering,anti-infective treatment,and suppression of inflammatory storms were implemented to control the condition.CONCLUSION DAA drugs significantly improve the cure rate of CHC.However,when patients have factors such as autoimmune attack,coinfection,or unclear hepatitis C virus genotype,close monitoring is required during DAA treatment.

文摘BACKGROUND In China,hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) is the most common liver failure characterized by serious clinical syndromes of liver decompensation with a very high mortality.Bacterial and/or fungal infections are the most common complications that are associated with high short-term mortality.Bacterial translocation from the intestine,impaired hepatic clearance,and immune paralysis of circulating immune cells are thought to contribute to infectious complications in liver failure.The control of bacterial and fungal infections is the key to improving HBV-ACLF outcomes.Active prevention,early diagnosis,and timely treatment of bacterial and fungal infections are essential for treating HBV-ACLF.AIM To investigate the frequency and role of bacterial and fungal infections in patients with HBV-ACLF.METHODS Patients with HBV-ACLF hospitalized at Taihe Hospital,Hubei University of Medicine from January 2014 to December 2017 were retrospectively enrolled.Patient-related information was retrieved from the hospital case database,including general information,blood biochemistry,complications,etc.According to the occurrence of secondary infection or not,the patients were divided into an infection group and a non-infection group.The sites,types,and incidences of bacterial and fungal infections and the influence of infections on the prognosis of HBV-ACLF were statistically analyzed.The risk factors for infections were assessed by unconditional logistic regression.RESULTS There were 174 cases of HBV-ACLF that met the enrollment criteria,of which 114 (65.52%) were diagnosed with infectious complications.Infections occurred in the abdominal cavity (87 cases),respiratory tract (51 cases),urinary tract (18 cases),and biliary tract (10 cases).Patients with infectious complications had a significantly higher 28-d mortality (70.18%,80/114) than those without (40.00%,24/60)(70.18% vs 40.00%,P < 0.05).And patients with infectious complications had a much higher incidence of non-infectious complications (54.39%,62/114)(54.39% vs 15.00%,P < 0.05),leading to an extremely high 28-d mortality of 88.71%(55/62)(P < 0.05).The grade of liver failure,period of hospital stay ≥ 30 d,age ≥ 45 years,and percentage of neutrophils > 70% were identified as risk factors for infectious complications.CONCLUSION The high incidence of infectious complications in patients with HBV-ACLF is associated with severity and deterioration of the disease and may contribute to the extremely high mortality of these patients.

文摘BACKGROUND Reports on bacterial infection(BI)in decompensated cirrhosis(DC)is mainly from alcoholic cirrhosis.The role of BI as a trigger or complication of acute-onchronic liver failure(ACLF)in patients with hepatitis B virus decompensated cirrhosis(HBV-DC)remains to be investigated.AIM To investigate the impact of BI on the outcomes of the patients with HBV-DC admitted into the hospital with or without ACLF.METHODS This retrospective study included patients with HBV-DC admitted to two tertiary centers in China.In-hospital overall survival,90-d transplant-free survival,5-year post-discharge survival,and cumulative incidence of ACLF were evaluated.Risk factors for death were analyzed considering liver transplantation as a competing event.RESULTS A total of 1281 hospitalized HBV-DC patients were included;284 had ACLF at admission.The overall prevalence of BI was 28.1%.The patients with BI had a significantly lower in-hospital survival and transplant-free 90-d survival than those without,in both the patients admitted with and without ACLF.The presence of BI significantly increased the risk of developing ACLF[subdistribution hazard ratio(sHR)=2.52,95%CI:1.75-3.61,P<0.001]in the patients without ACLF.In the patients discharged alive,those who had an episode of BI had a significantly lower 5-year transplant-free survival.BI was an independent risk factor for death in the patients admitted without ACLF(sHR=3.28,95%CI:1.93-5.57),while in ACLF admissions,the presence of pneumonia,but not other type of BI,independently increased the risk of death(sHR=1.87,95%CI:1.24-2.82).CONCLUSION BI triggers ACLF in patients with HBV-DC and significantly impairs short-term survival.HBV-DC patients should be monitored carefully for the development of BI,especially pneumonia,to avoid an adverse outcome.

文摘Background:Acute-on-chronic liver failure(ACLF)is a life-threatening syndrome defined as acute decompensation in patients with chronic liver disease.Liver transplantation(LT)is the most effective treatment.We aimed to assess the impact of cirrhosis-related complications pre-LT on the posttransplant prognosis of patients with ACLF.Methods:This was an observational cohort study conducted between January 2018 and December 2020.Clinical characteristics,cirrhosis-related complications at LT and patient survival post-LT were collected.All liver recipients with ACLF were followed for 1 year post-LT.Results:A total of 212 LT recipients with ACLF were enrolled,including 75(35.4%)patients with ACLF-1,64(30.2%)with ACLF-2,and 73(34.4%)with ACLF-3.The median waiting time for LT was 11(4-24)days.The most prevalent cirrhosis-related complication was ascites(78.8%),followed by hepatic encephalopathy(57.1%),bacterial infections(48.1%),hepatorenal syndrome(22.2%)and gastrointestinal bleeding(11.3%).Survival analyses showed that patients with complications at LT had a significantly lower survival probability at both 3 months and 1 year after LT than those without complications(all P<0.05).A simplified model was developed by assigning one point to each complication:transplantation for ACLF with cirrhosis-related complication(TACC)model.Risk stratification of TACC model identified 3 strata(≥4,=3,and≤2)with high,median and low risk of death after LT(P<0.001).Moreover,the TACC model showed a comparable ability for predicting the outcome post-LT to the other four prognostic models(chronic liver failure-consortium ACLF score,Chinese Group on the Study of Severe Hepatitis B-ACLF score,model for end-stage liver disease score and Child-Turcotte-Pugh score).Conclusions:The presence of cirrhosis-related complications pre-LT increases the risk of death post-LT in patients with ACLF.The TACC model based on the number of cirrhosis-related complications pre-LT could stratify posttransplant survival,which might help to determine transplant timing for ACLF.

文摘AIM:To investigate the short-term and long-term efficacy of entecavir versus lamivudine in patients with spontaneous reactivation of hepatitis B presenting as acute-on-chronic liver failure(ACLF).METHODS:This was a single center,prospective cohort study.Eligible,consecutive hospitalized patients received either entecavir 0.5 mg/d or lamivudine 100mg/d.All patients were given standard comprehensive internal medicine.The primary endpoint was survival rate at day 60,and secondary endpoints were reduction in hepatitis B virus(HBV)DNA and alanine aminotransferase(ALT)levels,and improvement in Child-Turcotte-Pugh(CTP)and model for end-stage liver disease(MELD)scores at day 60 and survival rate at week 52.RESULTS:One hundred and nineteen eligible subjects were recruited from 176 patients with severe acute exacerbation of chronic hepatitis B:65 were included in the entecavir group and 54 in the lamivudine group(full analysis set).No significant differences were found in patient baseline clinical parameters.At day 60,entecavir did not improve the probability of survival(P=0.066),despite resulting in faster virological suppression(P<0.001),higher rates of virological response(P<0.05)and greater reductions in the CTP and MELD scores(all P<0.05)than lamivudine.Intriguingly,at week 52,the probability of survival was higher in the entecavir group than in the lamivudine group[42/65(64.6%)vs 26/54(48.1%),respectively;P=0.038].The pretreatment MELD score(B,1.357;95%Cl:2.138-7.062;P=0.000)and virological response at day30(B,1.556;95%Cl:1.811-12.411;P=0.002),were found to be good predictors for 52-wk survival.CONCLUSION:Entecavir significantly reduced HBV DNA levels,decreased the CTP and MELD scores,and thereby improved the long-term survival rate in patients with spontaneous reactivation of hepatitis B presenting as ACLF.

文摘BACKGROUND Acute exacerbation in patients with chronic hepatitis B virus(HBV) infection results in different severities of liver injury. The risk factors related to progression to hepatic decompensation(HD) and acute-on-chronic liver failure(ACLF) in patients with severe acute exacerbation(SAE) of chronic HBV infection remain unknown.AIM To identify risk factors related to progression to HD and ACLF in compensated patients with SAE of chronic HBV infection.METHODS The baseline characteristics of 164 patients with SAE of chronic HBV infection were retrospectively reviewed. Independent risk factors associated with progression to HD and ACLF were identified. The predictive values of our previously established prediction model in patients with acute exacerbation(AE model) and the model for end-stage liver disease(MELD) score in predicting the development of ACLF were evaluated.RESULTS Among 164 patients with SAE, 83(50.6%) had compensated liver cirrhosis(LC),43 had progression to HD without ACLF, and 29 had progression to ACLF within 28 d after admission. Independent risk factors associated with progression to HD were LC and low alanine aminotransferase. Independent risk factors for progression to ACLF were LC, high MELD score, high aspartate aminotransferase(AST) levels, and low prothrombin activity(PTA). The area under the receiver operating characteristic of the AE model [0.844, 95%confidence interval(CI): 0.779-0.896] was significantly higher than that of MELD score(0.690, 95%CI: 0.613-0.760, P < 0.05) in predicting the development of ACLF.CONCLUSION In patients with SAE of chronic HBV infection, LC is an independent risk factor for progression to both HD and ACLF. High MELD score, high AST, and low PTA are associated with progression to ACLF. The AE model is a better predictor of ACLF development in patients with SAE than MELD score.

文摘AIM: To assess CD163 expression in plasma and peripheral blood and analyze its association with disease in acute-on-chronic hepatitis B liver failure (ACHBLF) patients. METHODS: A retrospective study was conducted from January 1, 2011 to January 1, 2012. Forty patients with ACHBLF (mean age 44.48 ± 12.28 years, range 18-69 years), 40 patients with chronic hepatitis B (CHB) (mean age 39.45 ± 12.22 years, range 21-57 years) and 20 ageand sex-matched healthy controls (mean age 38.35 ± 11.97 years, range 28-60 years) were included in this study. Flow cytometry was used to analyze the frequency of CD163+ peripheral blood mononuclear cells (PBMCs) and surface protein expression of CD163. Real-time transcription-polymerase chain re-action was performed to assess relative CD163 mRNA levels in PBMCs. Plasma soluble CD163 (sCD163) levels were measured by enzyme-linked immunosorbent assay. Clinical variables were also recorded. Comparisons between groups were analyzed by Kruskal-Wallis H test and Mann-Whitney U test. Statistical analyses were performed using SPSS 15.0 software and a P value < 0.05 was considered statistically significant. RESULTS: Flow cytometry showed that the population of CD163+ PBMCs was significantly greater in ACHBLF patients than in CHB patients and healthy controls (47.9645% ± 17.1542%, 32.0975% ± 11.0215% vs 17.9460% ± 6.3618%, P < 0.0001). However, there were no significant differences in mean fluorescence intensity of CD163+ PBMCs within the three groups (27.4975 ± 11.3731, 25.8140 ± 10.0649 vs 20.5050 ± 6.2437, P = 0.0514). CD163 mRNA expression in ACHBLF patients was significantly increased compared with CHB patients and healthy controls (1.41 × 10 -2 ± 2.18 × 10 -2 , 5.10 × 10 -3 ± 3.61 × 10 -3 vs 37.0 × 10 -4 ± 3.55 × 10 -4 , P = 0.02). Plasma sCD163 levels in patients with ACHBLF were significantly increased compared with CHB patients and healthy controls (4706.2175 ± 1681.1096 ng/mL, 1089.7160 ± 736.8395 ng/mL vs 435.9562 ± 440.8329 ng/mL, P < 0.0001). In ACHBLF patients, plasma sCD163 levels were significantly positively associated with model for end-stage liver disease scores (r = 0.5075, P = 0.008), hepatitis B virus-DNA (r = 0.6827, P < 0.0001), and negatively associated with prothrombin activity (r = -0.3348, P = 0.0347), but had no correlation with total bilirubin (r = 0.2551, P = 0.1122). Furthermore, sCD163 was obviously elevated in non-surviving patients compared with surviving patients with ACHBLF (5344.9080 ± 1589.5199 ng/mL vs 3641.7333 ± 1264.5228 ng/mL, P = 0.0321). CONCLUSION: CD163 and sCD163 may be related to disease severity and prognosis in ACHBLF patients.

文摘AIM:To determine the prognostic value of circulating indicators of cell death in acute-on-chronic liver failure(ACLF)patients with chronic hepatitis B virus(HBV)infection as the single etiology.METHODS:Full length and caspase cleaved cytokeratin 18(detected as M65 and M30 antigens)represent circulating indicators of necrosis and apoptosis.M65and M30 were identified by enzyme-linked immunosorbent assay in 169 subjects including healthy controls(n=33),patients with chronic hepatitis B(CHB,n=55)and patients with ACLF(n=81).According to the 3-mo survival period,ACLF patients were defined as having spontaneous recovery(n=33)and non-spontaneous recovery which included deceased patients and those who required liver transplantation(n=48).RESULTS:Both biomarker levels significantly increased gradually as liver disease progressed(for M65:P<0.001 for all;for M30:control vs CHB,P=0.072;others:P<0.001 for all).In contrast,the M30/M65 ratio was significantly higher in controls compared with CHB patients(P=0.010)or ACLF patients(P<0.001).In addition,the area under receiver operating characteristic curve(AUC)analysis demonstrated that both biomarkers had diagnostic value(AUC≥0.80)in identifying ACLF from CHB patients.Interestingly,it is worth noting that the M30/M65 ratio was significantly different between spontaneous and non-spontaneous recovery in ACLF patients(P=0.032).The prognostic value of the M30/M65 ratio was compared with the Model for End-Stage Liver Disease(MELD)and Child-Pugh scores at the 3-mo survival period,the AUC of the M30/M65ratio was 0.66 with a sensitivity of 52.9%and the highest specificity of 92.6%(MELD:AUC=0.71;sensitivity,79.4%;specificity,63.0%;Child-Pugh:AUC=0.77;sensitivity,61.8%;specificity,88.9%).CONCLUSION:M65 and M30 are strongly associated with liver disease severity.The M30/M65 ratio may be a potential prognostic marker for spontaneous recovery in patients with HBV-related ACLF.
文摘AIM To investigate whether the short-term prognosis of hepatitis B virus(HBV)-related acute-on-chronic liver failure(ACLF) could be improved by using a modified model for end-stage liver disease(MELD) including serum lactate.METHODS This clinical study was conducted at the First Affiliated Hospital, Fujian Medicine University, China. From 2009 to 2015, 236 patients diagnosed with HBV-related ACLF at our center were recruited for this 3-month followup study. Demographic data and serum lactate levels were collected from the patients. The MELD scores with or without serum lactate levels from survival and nonsurvival groups were recorded and compared.RESULTS Two hundred and thirty-six patients with HBV-ACLF were divided into two groups: survival group(S) andnon-survival group(NS). Compared with the NS group, the patients in survival the S group had a significantly lower level of serum lactate(3.11 ± 1.98 vs 4.67 ± 2.43, t = 5.43, P < 0.001) and MELD score(23.33 ± 5.42 vs 30.37 ± 6.58, t = 9.01, P = 0.023). Furthermore, serum lactate level was positively correlated with MELD score(r = 0.315, P < 0.001). Therefore, a modified MELD including serum lactate was developed by logistic regression analysis(0.314 × lactate + 0.172 × MELD-5.923). In predicting 3-month mortality using the MELD-LAC model, the patients from the S group had significantly lower baseline scores(-0.930 ± 1.34) when compared with those from the NS group(0.771 ± 1.32, t = 9.735, P < 0.001). The area under the receiver operating characteristic curve(AUROC) was 0.859 calculated by using the MELD-LAC model, which was significantly higher than that calculated by using the lactate level(0.790) or MELD alone(0.818). When the cutoff value was set at-0.4741, the sensitivity, specificity, positive predictive value and negative predictive value for predicting short-term mortality were 91.5%, 80.10%, 94.34% and 74.62%, respectively. When the MELD-LAC scores at baseline level were set at-0.5561 and 0.6879, the corresponding mortality rates within three months were 75% and 90%, respectively.CONCLUSION The short-term prognosis of HBV-related ACLF was improved by using a modified MELD including serum lactate from the present 6-year clinical study.

文摘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.
文摘BACKGROUND: Selection of drugs for antiviral therapy of patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF) remains difficult. This study was undertaken to evaluate the short-term efficacy of entecavir versus lamivudine on hepatitis B e antigen (HBeAg)-negative patients with ACLF. METHODS: The data of 182 HBeAg-negative patients with ACLF were retrospectively collected from patient profiles of the hospital. In these patients, 93 HBeAg-negative patients with ACLF were treated orally with 0.5 mg of entecavir and 89 were treated orally with 100 mg of lamivudine every day. The gender and age were matched between the two groups. Biochemical items, the model for end-stage liver disease (MELD) score, and HBV DNA level were matched at baseline between the two groups and monitored during treatment. The 3-month mortalities of the two groups were compared. RESULTS: No significant differences were found in biochemical items, MELD score, and HBV DNA level at baseline (P】0.05). HBV DNA level decreased within 3 months in both groups (P【0.05), regardless of the pretreatment MELD score. In patients with the same range of pretreatment MELD scores, treatment duration, posttreatment HBV DNA levels, percentage of HBV DNA level 【2.7 lg copies/mL, biochemical items, MELD scores and 3-month mortality were similar in the two groups (all P】0.05). Pretreatment MELD score was not related to posttreatment HBV DNA levels (P】0.05), but related to a 3-month mortality in both groups (both P【0.001).CONCLUSIONS: In HBeAg-negative patients with ACLF, the short-term efficacy of entecavir versus lamivudine was similar. The degree of pretreatment liver failure significantly affected the outcome of treatment.

文摘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.

文摘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/mL)had a higher mortality within 4 wk than those with low IL-6 levels(≤11.8 pg/mL)(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.

文摘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.

文摘BACKGROUNDHepatitis B virus-associated acute-on-chronic liver failure (HBV-ACLF) is animportant type of liver failure in Asia. There is a direct relationship between HBVACLFand gastrointestinal barrier function. However, the nutritional status ofHBV-ACLF patients has been poorly studied.AIMTo investigate the nutritional risk and nutritional status of HBV-ACLF patientsand evaluated the impact of nutritional support on the gastrointestinal barrier and28-d mortality.METHODSNutritional risk screening assessment and gastrointestinal barrier biomarkers ofpatients with HBV-ACLF (n = 234) and patients in the compensatory period ofliver cirrhosis (the control group) (n = 234) were compared during the periodbetween 2016 and 2018. Changes were analyzed after nutritional support in HBVACLFpatients. Valuable biomarkers have been explored to predict 28-d death.The 28-d survival between HBV-ACLF patients with nutritional support (n = 234)or no nutritional support (2014-2016) (n = 207) was compared.RESULTSThe nutritional risk of the HBV-ACLF patients was significantly higher than thatof the control group. The nutritional intake of the patients with HBV-ACLF waslower than that of the control group. The decrease in skeletal muscle and fatcontent and the deficiency of fat intake were more obvious (P < 0.001). Thecoccus-bacillus ratio, secretory immunoglobulin A, and serum D-lactate weresignificantly increased in HBV-ACLF patients. The survival group had a lowernutritional risk, lower D-lactate, and cytokine levels (endotoxin, tumor necrosisfactor alpha, interleukin-10, and interleukin-1). Interleukin-10 may be a potentialpredictor of death in HBV-ACLF patients. The 28-d survival of the nutritionalsupport group was better than that of the non-nutritional support group (P =0.016).CONCLUSIONPatients with HBV-ACLF have insufficient nutritional intake and high nutritionalrisk, and their intestinal barrier function is impaired. Individualized and dynamicnutritional support is associated with a better prognosis of 28-d mortality in HBVACLFpatients.

文摘Background:Hepatitis B virus-related acute-on-chronic liver failure(HBV-ACLF)has a high short-term mortality.However,the treatment progression for HBV-ACLF in China in the past decade has not been well characterized.The present study aimed to determine whether the HBV-ACLF treatment has significantly improved during the past decade.Methods:This study retrospectively compared short-term(28/56 days)survival rates of two different nationwide cohorts(cohort I:2008-2011 and cohort II:2012-2015).Eligible HBV-ACLF patients were enrolled retrospectively.Patients in the cohorts I and II were assigned either to the standard medical therapy(SMT)group(cohort I-SMT,cohort II-SMT)or artificial liver support system(ALSS)group(cohort IALSS,cohort II-ALSS).Propensity score matching analysis was conducted to eliminate baseline differences,and multivariate logistic regression analysis was used to explore the independent factors for 28-day survival.Results:Short-term(28/56 days)survival rates were significantly higher in the ALSS group than those in the SMT group(P<0.05)and were higher in the cohort II than those in the cohort I(P<0.001).After propensity score matching,short-term(28/56 days)survival rates were higher in the cohort II than those in the cohort I for both SMT(60.7%vs.53.0%,50.0%vs.39.8%,P<0.05)and ALSS(66.1%vs.56.5%,53.0%vs.44.4%,P<0.05)treatments.The 28-day survival rate was higher in patients treated with nucleos(t)ide analogs than in patients without such treatments(P=0.046).Multivariate logistic regression analysis revealed that ALSS(OR=0.962,95%CI:0.951-0.973,P=0.038),nucleos(t)ide analogs(OR=0.927,95%CI:0.871-0.983,P=0.046),old age(OR=1.028,95%CI:1.015-1.041,P<0.001),total bilirubin(OR=1.002,95%CI:1.001-1.003,P=0.004),INR(OR=1.569,95%CI:1.044-2.358,P<0.001),COSSH-ACLF grade(OR=2.683,95%CI:1.792-4.017,P<0.001),and albumin(OR=0.952,95%CI:0.924-0.982,P=0.002)were independent factors for 28-day mortality.Conclusions:The treatment for patients with HBV-ACLF has improved in the past decade.
