Dengue induced acute liver failure:A meta summary of case reports

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.

Lymphocyte-to-white blood cell ratio is associated with outcome in patients with hepatitis B virus-related acute-on-chronic liver failure

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.

Risk factors for progression to acute-on-chronic liver failure during severe acute exacerbation of chronic hepatitis B virus infection

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.

Effect of extracorporeal bioartificial liver support system on fulminant hepatic failure rabbits

AIM To evaluate the possibility of usingcultured human hepatocytes as a bridge betweenbioartificial liver and liver transplantation.METHODS In this experiment,the efficacy ofextracorporeal bioartificial liver support system(EBLSS)consisting of spheriodal human livercells and cultured hepatocytes supernatant wasassessed in vivo using galactosamine inducedrabbit model of fulminant hepatic failure.RESULTS There was no difference of survivalbetween the two groups of rabbits,but in thesupported rabbits serum alanineaminotransferase,total bilirubin and creatininewere significantly lower and hepatocyte necrosiswas markedly milder than those in controlanimals.In addition,a good viability of humanliver cells was noted after the experiment.CONCLUSION EBLSS plays a biologic role inmaintaining and compensating the function ofthe liver.

Prognostic value of M30/M65 for outcome of hepatitis B virus-related acute-on-chronic liver failure

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. M65 and 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/M65 ratio 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.

Artificial liver support in pigs with acetaminophen-induced acute liver failure

AIM To establish a reversible porcine model of acute liver failure(ALF) and treat it with an artificial liver system. METHODS Sixteen pigs weighing 30-35 kg were chosen and administered with acetaminophen(APAP) to induce ALF. ALF pigs were then randomly assigned to either an experimental group(n = 11), in which a treatment procedure was performed, or a control group(n = 5). Treatment was started 20 h after APAP administration and continued for 8 h. Clinical manifestations of all animals, including liver and kidney functions, serum biochemical parameters and survival times were analyzed. RESULTS Twenty hours after APAP administration, the levels of serum aspartate aminotransferase, total bilirubin, creatinine and ammonia were significantly increased, while albumin levels were decreased(P < 0.05). Prothrombin time was found to be extended with progression of ALF. After continuous treatment for 8 h(at 28 h), aspartate aminotransferase, total bilirubin, creatinine, and ammonia showed a decrease in comparison with the control group(P < 0.05). A cross-section of livers revealed signs of vacuolar degeneration, nuclear fragmentation and dissolution.Concerning survival, porcine models in the treatment group survived for longer times with artificial liver system treatment(P < 0.05). CONCLUSION This model is reproducible and allows for quantitative evaluation of new liver systems, such as a bioartificial liver. The artificial liver system(ZHj-3) is safe and effective for the APAP-induced porcine ALF model.

Progress in hepatitis B virus-related acute-on-chronic liver failure treatment in China:A large,multicenter,retrospective cohort study using a propensity score matching analysis

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.

Efficacy of liver transplantation for acute hepatic failure:asingle-center experience

BACKGROUND:Acute hepatic failure (AHF) is a devastating clinical syndrome with a high mortality rate.The outcome of AHF varies with etiology,but liver transplantation (LT) can significantly improve the prognosis and survival rate of such patients.This study aimed to detect the role of LT and artificial liver support systems (ALSS) for AHF patients and to analyze the etiology and outcome of patients with this disease.METHODS:A retrospective analysis was made of 48 consecutive patients with AHF who fulfilled the Kings College Criteria for LT at our center.We analyzed and compared the etiology,outcome,prognosis,and survival rates of patients between the transplantation (LT) group and the non-transplantation (N-LT) group.RESULTS:AHF was due to viral hepatitis in 25 patients (52.1%;hepatitis B virus in 22),drug or toxic reactions in 14 (29.2%;acetaminophen in 6),Wilson disease in 4 (8.3%),unknown reasons in 3 (6.3%),and miscellaneous conditions in 2 (4.2%).In the LT group,36 patients (7 underwent living donor LT,and 29 cadaveric LT) had an average model for endstage liver disease score (MELD) of 35.7.Twenty-eight patients survived with good graft function after a follow-up of 27.3± 4.5 months.During the waiting time,6 patients were treated with ALSS and 2 of them died during hospitalization.The 30-day,12-month,and 18-month survival rates were 77.8%,72.2%,and 66.7%,respectively.In the N-LT group,12 patients had an average MELD score of 34.5.Four patients were treated with ALSS and all died during hospitalization.The 90-day and 1-year survival rates were only 16.7% and 8.3%,respectively.CONCLUSIONS:Hepatitis is the most prominent cause of AHF at our center.Most patients with AHF,who fulfill the Kings College Criteria for LT,did not survive longer without LT.ALSS did not improve the prognosis of AHF patients,but may extend the waiting time for a donor.Currently,LT is still the most effective way to improve the prognosis of AHF patients.

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

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

Fulminant Hepatitis Associated with Chronic Consumption of 3,4-Methylenedioxy-Methamphetamine;Case Report

The amphetamine derivative 3,4-methylenedioxymethamphetamine (MDMA), also called ecstasy, is a neurotoxin widely consumed among young people that has increased in recent years because it is a recreational drug, of which immediate effects are known such as a greater sensation of well-being, extroversion, increased sensory perception. However, its long-term effects have been described very little in the medical literature, including damage to the heart, central nervous system, kidney, etc. One of its little-known effects is hepatotoxicity, of which few cases are known associated with fulminant hepatitis, which is a rapidly deteriorating condition that is generally associated with a syndrome of multiple organ dysfunction and death. Therefore, it is very important to know this type of damage in the short and long term. The following case is of a 39-year-old man who came to our service due to jaundice syndrome and the only history of MDMA consumption, who as the days went by met the criteria for fulminant liver failure, with damage to multiple organs (organ dysfunction syndrome).

Nursing of Artificial Liver Support System in the Treatment of Severe

Objective:Research on nursing method of artificial liver support system applied in severe hepatitis patients.Methods:Selected 50 severe hepatitis patients in our hospital during the period of January 2018 and January 2019,observed and analyzed the clinical intervention effect of all treated by artificial liver support system cooperating with related nursing methods.Results:After the treatment,the clinical symptoms and abdominal distension of the patients were relieved,whose spirit took a turn for the better and the jaundice subsided.Among these patients,68%got improved enough to be released,26.00%gave up for financial concerns and 6.00%died.Before and after treatment,the patients’PT and INR,APTT,TT improved obviously,and the difference were quite a lot(P<0.05),while ALT and ALB showed few without any statistical significance(P>0.05).Conclusion:During the treatment and intervention of severe hepatitis patients with artificial liver support system,effective nursing interventions are needed,mainly including completely preoperative,intraoperative and postoperative care so as to ensure the treatment effect and promote the recovery of intervention,which has remarkable significance to clinical development.

Experimental study of bioartificial liver with cultured human liver cells

AIM To establish an extracorporeal bioartificial liver support system (EBLSS) using cultured human liver cells and to study its support effect for fulminant hepatic failure (FHF).METHODS The liver support experiment of EBLSS consisting of aggregates cultured human liver cells, hollow fiber bioreactor, and circulation unit was carried out in dizhepatic dogs.RESULTS The viability of isolated hepatocytes and nonparenchymal liver cells reached 96%. These cells were successfully cultured as multicellular spheroids with synthetic technique. The typical morphological appearance was retained up to the end of the artificial liver experiment. Compared with the control dogs treated with EBLSS without liver cells, the survival time of artificial liver support dogs was significantly prolonged. The changes of blood pressure, heart rate and ECG were slow. Both serum ammonia and lactate levels were significantly lowered at the 3rd h and 5th h. In addition, a good viability of human liver cells was noted after 5 h experiment.CONCLUSION EBLSS playing a metabolic role of cultured human hepatocytes, is capable of compensating the function of the liver, and could provide effective artificial liver support and therapy for patients with FHF.

Acute fatty liver of pregnancy associated with severe acute pancreatitis:A case report

Acute fatty liver of pregnancy is a rare disease that affects women in the third trimester of pregnancy. Although infrequent, the disease can cause maternal mortality. The diagnosis is not always clear until the pregnancy is terminated, and significant complications, such as acute pancreatitis, can occur. Pancreatic involvement typically only occurs in severe cases after the development of hepatic and renal impairment. To date, little knowledge is available regarding how the disease causes pancreatitis. Treatment involves supportive measures and pregnancy interruption. In this report, we describe a case of a previously healthy 26-year-old woman at a gestational age of 27 wk and 6 d who was admitted with severe abdominal pain and vomiting. This case illustrates the clinical and laboratory overlap between acute fatty liver of pregnancy and pancreatitis, highlighting the difficulties in differentiating each disease. Furthermore, the hypothesis for this overlapping is presented, and the therapeutic options are discussed.

目的探讨乙型肝炎病毒(HBV)相关肝衰竭患者人工肝治疗预后预测指标的应用意义。方法回顾性分析2019年1月至2021年12月于赣州市第五人民医院初次接受人工肝治疗的90例HBV相关肝衰竭患者的临床资料,按人工肝治疗方法分为血浆置换(PE)组和PE+血液滤过透析(CHDF)治疗(PE+CHDF)组,每组45例。收集患者临床资料,比较两组治疗前后肝功能及凝血功能变化,随访患者肝移植情况,单因素及多因素Logistic回归分析人工肝治疗后患者90d预后的影响因素。并按照患者90d预后结局分为存活组及死亡组,比较两组各项生化指标及终末期肝病模型(MELD)评分、MELD联合血清钠(Na)评分等指标对预后的预测价值。结果治疗4周,PE+CHDF组好转率为93.33%,高于PE组的71.11%,差异有统计学意义(P<0.05)。治疗后,两组丙氨酸氨基转移酶(ALT)、天门冬氨酸氨基转移酶(AST)、总胆红素(TBiL)水平均低于治疗前,凝血酶原时间(PT)短于治疗前,且PE+CHDF组ALT、AST、TBiL水平均低于PE组,PT短于PE组,差异有统计学意义(P<0.05);PE+CHDF组与PE组白蛋白(ALB)水平与治疗前及组间比较差异无统计学意义。存活组与死亡组性别、年龄、ALT水平、AST水平、ALB水平、HBV-DNA、肌酐(Cr)水平、肝性脑病、肝硬化占比、腹水、肝肾综合征占比比较差异无统计学意义;存活组TBiL水平、单核细胞-淋巴细胞比例(MLR)、中性粒细胞-淋巴细胞比例(NLR)、Cr水平、MELD评分、MELD-Na评分、NLR、国际标准化比值(INR)均低于死亡组,PT短于死亡组,甲胎蛋白高于死亡组,差异有统计学意义(P<0.05)。多因素Logistic回归分析结果显示,NLR升高、MELD评分升高、MELD-Na升高、MLR升高是人工肝治疗后患者90d死亡的危险因素(P<0.05)。Spearson相关性分析结果显示,NLR、MLR、MELD评分、MELD-Na评分与90d预后呈正相关(r>0,P<0.05)。MELD预测短期预后的灵敏度为82.14%、特异度为80.65%,MELD-Na评分预测短期预后的灵敏度为92.90%、特异度为88.71%,NLR预测短期预后的灵敏度为96.43%、特异度为98.39%%,MLR预测短期预后的灵敏度为92.86%、特异度为98.39%。结论MELD评分、NLR、MLR、MELD-Na评分对判定人工肝治疗短期预后均具有重要意义,可作为预测患者短期预后的重要因子。
