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:Serum thymosinβ4 levels were measured in 30 patients with acute-on-chronic liver failure(ACLF), 31 patients with chronic liver failure(CLF),30 patients with compensated liver cirrhosis(CR)and 32 patients with chronic hepatitis B and 30 healthy controls.Serum thymosinβ4 levels were measured by enzyme-linked immunosorbent assay and Child-Pugh and model for end-stage liver disease(MELD)scores were calculated for each patient on admission.RESULTS:Compared with healthy controls,serum thymosinβ4 levels in ACLF,CLF,CR and chronic hepatitis B patients were significantly lower,6.5047 (4.7879-10.5314)μg/mL vs 0.4632(0.2759-0.8768) μg/mL,0.6981(0.5209-1.2008)μg/mL,1.8053 (0.8110-2.3397)μg/mL,3.7803(1.8570-6.4722)μg/mL, respectively(P<0.001).The levels of thymosinβ4 in liver failure(ACLF or CLF)patients were markedly lower than that in CR(P<0.001),and a difference was also found between CLF and ACLF patients(P=0.038).In patients with chronic liver disease,there was a positive relationship between thymosinβ4 levels and albumin, choline esterase,and platelet(P<0.001),and negative relationship with alanine aminotransferase(P=0.020), aspartate aminotransferase,total bilirubin,international normalized ratio of prothrombin time,and Child-Pugh and MELD scores(P<0.001).Of the 61 liver failure patients,the thymosinβ4 levels of non-survivors were significantly lower than that of survivors(P=0.007). Receiver operating characteristics analysis identified a thymosinβ4 cutoff level of 0.5708μg/mL for predicting poor prognosis in all liver failure patients.The serial thymosinβ4 values were observed in 13 liver failure inpatients.Lower initial values were observed in the death.While greater improvement in thymosinβ4 value was found in those who recovered from the disease. CONCLUSION:Serum thymosinβ4 can be used as an important potential predictor for liver failure caused by chronic HBV infection.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

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

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 Neutrophil-lymphocyte ratio(NLR),fibrosis index based on four factors(Fib4),aspartate aminotransferase-to-platelet ratio index(APRI)can be used for prognostic evaluation of hepatocellular carcinoma.However,no study has established an individualized prediction model for the prognosis of hepatocellular carcinoma based on these factors.AIM To screen the factors that affect the prognosis of hepatocellular carcinoma and establish a nomogram model that predicts postoperative liver failure after hepatic resection in patients with hepatocellular carcinoma.METHODS In total,220 patients with hepatocellular carcinoma treated in our hospital from January 2022 to January 2023 were selected.They were divided into 154 participants in the modeling cohort,and 66 in the validation cohort.Comparative analysis of the changes in NLR,Fib4,and APRI levels in 154 patients with hepatocellular carcinoma before liver resection and at 3 mo,6 mo,and 12 mo postoperatively was conducted.Binary logistic regression to analyze the influencing factors on the occurrence of liver failure in hepatocellular carcinoma patients,roadmap prediction modeling,and validation,patient work characteristic curves(ROCs)to evaluate the predictive efficacy of the model,calibration curves to assess the consistency,and decision curve analysis(DCA)to evaluate the model’s validity were also conducted.RESULTS Binary logistic regression showed that Child-Pugh grading,Surgical site,NLR,Fib4,and APRI were all risk factors for liver failure after hepatic resection in patients with hepatocellular carcinoma.The modeling cohort built a column-line graph model,and the area under the ROC curve was 0.986[95%confidence in terval(CI):0.963-1.000].The patients in the validation cohort utilized the column-line graph to predict the probability of survival in the validation cohort and plotted the ROC curve with an area under the curve of the model of 0.692(95%CI:0.548-0.837).The deviation of the actual outcome curves from the calibration curves of the column-line plots generated by the modeling and validation cohorts was small,and the DCA confirmed the validity.CONCLUSION NLR,Fib4,and APRI independently influence posthepatectomy liver failure in patients with hepatocellular carcinoma.The column-line graph prediction model exhibited strong prognostic capability,with substantial concordance between predicted and actual events.

文摘On the basis of real-world clinical data,the study aimed to explore the effect and mechanisms of the treatment plan of“traditional Chinese medicine(TCM)regulating liver regeneration.”A total of 457 patients with HBV-related liver failure were retrospectively collected.The patients were divided into three groups:the modern medicine control group(MMC group),patients treated with routine medical treatment;the control group combining traditional Chinese and Western medicine(CTW),patients treated with routine medical treatment plus the common TCM formula;and the treatment group of“TCM regulating liver regeneration”(RLR),patients treated with both routine medical treatment and the special TCM formula of RLR.After 8 weeks of treatment,the mortality of patients in the RLR group(12.31%)was significantly lower than those in the MMC(50%)and CTW(29.11%)groups.Total bilirubin level significantly decreased and albumin increased in the RLR group when compared with the MMC and CTW groups(P<0.05).In addition,there were significant differences in the expression of several cytokines related to liver regeneration in the RLR group compared with the MMC group.RLR treatment can decrease jaundice,improve liver function,and significantly reduce the mortality in patients with HBV-related liver failure.The mechanism may be related to the role of RLR treatment in influencing cytokines related to liver regeneration.

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 Acute liver failure(ALF)may be the first and most dramatic presentation of Wilson’s disease(WD).ALF due to WD(WD-ALF)is difficult to distinguish from other causes of liver disease and is a clear indication for liver transplantation.There is no firm recommendation on specific and supportive medical treatment for this condition.AIM To critically evaluate the diagnostic and therapeutic management of WD-ALF patients in order to improve their survival with native liver.METHODS A retrospective analysis of patients with WD-ALF was conducted in two pediatric liver units from 2018 to 2023.RESULTS During the study period,16 children(9 males)received a diagnosis of WD and 2 of them presented with ALF.The first was successfully treated with an unconventional combination of low doses of D-penicillamine and zinc plus steroids,and survived without liver transplant.The second,exclusively treated with supportive therapy,needed a hepatotransplant to overcome ALF.CONCLUSION Successful treatment of 1 WD-ALF patient with low-dose D-penicillamine and zinc plus steroids may provide new perspectives for management of this condition,which is currently only treated with liver transplantation.
文摘Acute liver failure(ALF)is a rare cause of liver-related mortality worldwide,with an estimated annual global incidence of more than one million cases.While drug-induced liver injury,including acetaminophen toxicity,is the leading cause of ALF in the Western world,viral infections remain a significant cause of ALF and the most common cause in many developing nations.Given the high mortality rates associated with ALF,healthcare providers should be aware of the broad range of viral infections that have been implicated to enable early diagnosis,rapid treatment initiation when possible,and optimal management,which may include liver transplantation.This review aims to provide a summary of viral causes of ALF,diagnostic approaches,treatment options,and expected outcomes.
文摘BACKGROUND Dengue fever is the most common cause of viral hemorrhagic fever,with more than 400 million cases being reported annually,worldwide.Even though hepatic involvement is common,acute liver failure(ALF)is a rare complication of dengue fever.AIM To analyze the demographic profile,symptomology,hospital course and outcomes of patients presenting with ALF secondary to dengue infection by reviewing the published case reports.METHODS A systematic search was performed from multiple databases including PubMed,Reference Citation Analysis,Science Direct,and Google Scholar.The search terms used were"dengue"OR"severe dengue"OR"dengue shock syndrome"OR"dengue haemorrhagic syndrome"OR"dengue fever"AND"acute liver failure"OR"hepatic failure"OR"liver injury".The inclusion criteria were:(1)Case reports or case series with individual patient details;(2)Reported acute liver failure secondary to dengue infection;and(3)Published in English language and on adult humans.The data were extracted for patient demographics,clinical sympto-matology,clinical interventions,hospital and intensive care unit course,need for organ support and clinical outcomes.RESULTS Data from 19 case reports fulfilling the predefined inclusion criteria were included.The median age of patients was 38 years(inter quartile range:Q3-Q126.5 years)with a female preponderance(52.6%).The median days from diagnosis of dengue to development of ALF was 4.5 d.The increase in aspartate aminotransferase was higher than that in alanine aminotransferase(median 4625 U/L vs 3100 U/L).All the patients had one or more organ failure,with neurological failure present in 73.7%cases.42.1%patients required vasopressor support and hepatic enceph-alopathy was the most reported complication in 13(68.4%)cases.Most of the patients were managed conser-vatively and 2 patients were taken up for liver transplantation.Only 1 death was reported(5.3%).CONCLUSION Dengue infection may rarely lead to ALF.These patients may frequently require intensive care and organ support.Even though most of these patients may improve with supportive care,liver transplantation may be a therapeutic option in refractory cases.

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Acute on chronic liver failure(ACLF)is a disease entity with a high mortality rate.The acute event arises from drugs and toxins,viral infections,bacterial sepsis,interventions(both surgical and non-surgical)and vascular events on top of a known or occult chronic liver disease.ACLF secondary to reactivation of chronic hepatitis B virus is a distinct condition;the high mortality of which can be managed in the wake of new potent antiviral therapy.For example,lamivudine and entecavir use has shown definite short-term survival benefits,even though drug resistance is a concern in the former.The renoprotective effects of telbivudine have been shown in a few studies to be useful in the presence of renal dysfunction.Monotherapy with newer agents such as tenofovir and a combination of nucleos(t)ides is promising for improving survival in this special group of liver disease patients.This review describes the current status of potent antiviral therapy in patient with acute on chronic liver failure due to reactivation of chronic hepatitis B,thereby providing an algorithm in management of such patients.

文摘AIM:To investigate whether serum thymosinβ4 can provide diagnostic or prognostic information in liver failure patients caused by chronic hepatitis B virus(HBV) infection. METHODS:Serum thymosinβ4 levels were measured in 30 patients with acute-on-chronic liver failure(ACLF), 31 patients with chronic liver failure(CLF),30 patients with compensated liver cirrhosis(CR)and 32 patients with chronic hepatitis B and 30 healthy controls.Serum thymosinβ4 levels were measured by enzyme-linked immunosorbent assay and Child-Pugh and model for end-stage liver disease(MELD)scores were calculated for each patient on admission.RESULTS:Compared with healthy controls,serum thymosinβ4 levels in ACLF,CLF,CR and chronic hepatitis B patients were significantly lower,6.5047 (4.7879-10.5314)μg/mL vs 0.4632(0.2759-0.8768) μg/mL,0.6981(0.5209-1.2008)μg/mL,1.8053 (0.8110-2.3397)μg/mL,3.7803(1.8570-6.4722)μg/mL, respectively(P<0.001).The levels of thymosinβ4 in liver failure(ACLF or CLF)patients were markedly lower than that in CR(P<0.001),and a difference was also found between CLF and ACLF patients(P=0.038).In patients with chronic liver disease,there was a positive relationship between thymosinβ4 levels and albumin, choline esterase,and platelet(P<0.001),and negative relationship with alanine aminotransferase(P=0.020), aspartate aminotransferase,total bilirubin,international normalized ratio of prothrombin time,and Child-Pugh and MELD scores(P<0.001).Of the 61 liver failure patients,the thymosinβ4 levels of non-survivors were significantly lower than that of survivors(P=0.007). Receiver operating characteristics analysis identified a thymosinβ4 cutoff level of 0.5708μg/mL for predicting poor prognosis in all liver failure patients.The serial thymosinβ4 values were observed in 13 liver failure inpatients.Lower initial values were observed in the death.While greater improvement in thymosinβ4 value was found in those who recovered from the disease. CONCLUSION:Serum thymosinβ4 can be used as an important potential predictor for liver failure caused by chronic HBV infection.
文摘Acute hepatic failure due to hepatitis B virus(HBV)can occur both during primary infection as well as after reactivation of chronic infection.Guidelines recommend considering antiviral therapy in both situations,although evidence supporting this recommendation is weak.Since HBV is not directly cytopathic,the mechanism leading to fulminant hepatitis B is thought to be primarily immunemediated.Therefore,immunosuppression combined with antiviral therapy might be a preferred therapeutic intervention in acute liver failure in hepatitis B.Here wereport our favourable experience in three hepatitis B patients with fulminant hepatic failure who were treated by combining high-dose steroid therapy with standard antiviral treatment,which resulted in a rapid improvement of clinical and liver parameters.

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.
