Palliative long-term abdominal drains vs large volume paracenteses for the management of refractory ascites in end-stage liver disease

BACKGROUND Long-term abdominal drains(LTAD)are a cost-effective palliative measure to manage malignant ascites in the community,but their use in patients with end-stage chronic liver disease and refractory ascites is not routine practice.The safety and cost-effectiveness of LTAD are currently being studied in this setting,with preliminary positive results.We hypothesised that palliative LTAD are as effective and safe as repeat palliative large volume paracentesis(LVP)in patients with cirrhosis and refractory ascites and may offer advantages in patients’quality of life.AIM To compare the effectiveness and safety of palliative LTAD and LVP in refractory ascites secondary to end-stage chronic liver disease.METHODS A retrospective,observational cohort study comparing the effectiveness and safety outcomes of palliative LTAD and regular palliative LVP as a treatment for refractory ascites in consecutive patients with end-stage chronic liver disease followed-up at our United Kingdom tertiary centre between 2018 and 2022 was conducted.Fisher’s exact tests and the Mann-Whitney U test were used to compare qualitative and quantitative variables,respectively.Kaplan-Meier survival estimates were generated to stratify time-related outcomes according to the type of drain.RESULTS Thirty patients had a total of 35 indwelling abdominal drains and nineteen patients underwent regular LVP.The baseline characteristics were similar between the groups.Prophylactic antibiotics were more frequently prescribed in patients with LTAD(P=0.012),while the incidence of peritonitis did not differ between the two groups(P=0.46).The incidence of acute kidney injury(P=0.014)and ascites/drain-related hospital admissions(P=0.004)were significantly higher in the LVP group.The overall survival was similar in the two groups(log-rank P=0.26),but the endpoint-free survival was significantly shorter in the LVP group(P=0.003,P<0.001,P=0.018 for first ascites/drain-related admission,acute kidney injury and drain-related complications,respectively).CONCLUSION The use of LTAD in the management of refractory ascites in palliated end-stage liver disease is effective,safe,and may reduce hospital admissions and utilisation of healthcare resources compared to LVP.

Endoscopic ultrasound-guided intraportal injection of autologous bone marrow in patients with decompensated liver cirrhosis:A case series

BACKGROUND Recently,stem cell therapy has been extensively studied as a promising treatment for decompensated liver cirrhosis(DLC).Technological advances in endoscopic ultrasonography(EUS)have facilitated EUS-guided portal vein(PV)access,through which stem cells can be precisely infused.AIM To investigate the feasibility and safety of fresh autologous bone marrow injection into the PV under EUS guidance in patients with DLC.METHODS Five patients with DLC were enrolled in this study after they provided written informed consent.EUS-guided intraportal bone marrow injection with a 22G FNA needle was performed using a transgastric,transhepatic approach.Several parameters were assessed before and after the procedure for a follow-up period of 12 mo.RESULTS Four males and one female with a mean age of 51 years old participated in this study.All patients had hepatitis B virus-related DLC.EUS-guided intraportal bone marrow injection was performed in all patients successfully without any complications such as hemorrhage.The clinical outcomes of the patients revealed improvements in clinical symptoms,serum albumin,ascites,and Child-Pugh scores throughout the 12-mo follow-up.CONCLUSION The use of EUS-guided fine needle injection for intraportal delivery of bone marrow was feasible and safe and appeared effective in patients with DLC.This treatment may thus be a safe,effective,non-radioactive,and minimally invasive treatment for DLC.

Acute-on-chronic liver failure in a multi-ethnic Asian city:A comparison of patients identified by Asia-Pacific Association for the Study of the Liver and European Association for the Study of the Liver definitions

AIM To explore the applicability of the Asia-Pacific Association for the Study of the Liver(APASL) and European Association for the Study of the Liver(EASL) guidelines for acute-on-chronic liver failure(ACLF) in profiling patients and determining the outcome.METHODS Patients admitted to a tertiary hospital in Singapore with acute decompensation of liver disease from January 2004to July 2014 are screened for ACLF according to the APASL and EASL criteria. The patients' data(including basic demographics, information about existing chronic liver disease, information about the acute decompensation, relevant laboratory values during admission, treatment, and outcome) are retrospectively analyzed to determine the background, precipitating factors and outcome.RESULTS A total of 458 liver patients is analyzed, and 78 patients with ACLF are identified. Sixty-three patients(80.8%) meet the APASL criteria, 64 patients(82.1%) meet the EASL criteria, and 49 patients(62.8%) fulfilled both criteria. The most common causes of acute liver injury are bacterial infections(59.0%), hepatitis B flare(29.5%), and variceal bleeding(24.4%). The common aetiologies of the underlying chronic disease included hepatitis B(43.6%), alcoholic(20.5%) and cryptogenic(11.5%) liver disease. The overall mortality rate is 61.5%. Increased age, the number of organ failures(as per CLIF-SOFA score), peak creatinine, INR, and amylase levels are associated with increased mortality or the need for liver transplantation. 14.3% of patients undergo liver transplantation with a 100% 1-year survival rate. CONCLUSION Both APASL and EASL criteria have identified ACLF patients with high three-month mortality, but those who fulfill APASL criteria alone have a better survival.

Hepatic recompensation according to Baveno VII criteria via transjugular intrahepatic portosystemic shunt

Transjugular intrahepatic portosystemic shunt is a therapeutic modality done through interventional radiology.It is aimed to decrease portal pressure in special situations for patients with decompensated liver disease with portal hypertension.It represents a potential addition to the therapeutic modalities that could achieve hepatic recompensation in those patients based on Baveno VII criteria.

Pregnancy Complicated With a Giant Pancreatic Tumor and Decompensation of Liver Cirrhosis:A Case Report and Literature Review

Pregnancy with solid pseudopapillary tumor of the pancreas(SPTP)is rare.Because pregnancy hormones may cause tumor progression,the management and treatment of SPTP need to balance the safety of pregnant women and fetuses with surgical treatment.We reported a case of a giant pancreatic tumor diagnosed during pregnancy that was considered to be SPTP.Examinations also showed hepatitis B virus infection and severe decompensation of liver cirrhosis.Medical termination of pregnancy was performed.The patient has lived with the tumor until now without surgery.We retrieved the published case reports,summarized the clinical characteristics of pregnancy with SPTP,and explored its management during the perinatal period.Most patients with SPTP have a good prognosis with good maternal and fetal outcomes,and it is important to choose an appropriate treatment method and timing.However,pregnancy combined with decompensated liver cirrhosis needs to be terminated in a timely manner because of its high-risk status.

Acute-on-chronic liver failure：recent update

Acute on chronic liver failure（ACLF） was first described in 1995 as a clinical syndrome distinct to classic acute decompensation.Characterized by complications of decompensation,ACLF occurs on a background of chronic liver dysfunction and is associated with high rates of organ failure and significant short-term mortality estimated between45%and 90%.Despite the clinical relevance of the condition,it still remains largely undefined with continued disagreement regarding its precise etiological factors,clinical course,prognostic criteria and management pathways.It is concerning that,despite our relative lack of understanding of the condition,the burden of ACLF among cirrhotic patients remains significant with an estimated prevalence of 30.9%.This paper highlights our current understanding of ACLF,including its etiology,diagnostic and prognostic criteria and pathophysiology.It is evident that further refinement of the ACLF classification system is required in order to detect high-risk patients and improve short-term mortality rates.The field of metabolomics certainly warrants investigation to enhance diagnostic and prognostic parameters,while the use of granulocyte-colony stimulating factor is a promising future therapeutic intervention for patients with ACLF.

Efficacy of dexamethasone and N-acetylcysteine combination in preventing post-embolization syndrome after transarterial chemoembolization in hepatocellular carcinoma

BACKGROUND Conventional transarterial chemoembolization(cTACE)is the current standard treatment for intermediate-stage hepatocellular carcinoma(HCC).Postembolization syndrome(PES)is complex clinical syndrome that presents as fever,abdominal pain,nausea,and vomiting.Either dexamethasone(DEXA)or Nacetylcysteine(NAC)is used to prevent PES;however,the synergistic effect of their combined therapy for preventing PES and liver decompensation has not been determined.AIM To evaluate the efficacy of DEXA and NAC combination in preventing PES and liver decompensation after cTACE.METHODS Patients with Barcelona Clinic Liver Cancer stage A or B HCC who were scheduled for TACE were prospectively enrolled.All patients were randomly stratified to receive NAC and DEXA or placebo.The dual therapy(NAC+DEXA)group received intravenous administration of 10 mg DEXA every 12 h,NAC 24 h prior to cTACE(150 mg/kg/h for 1 h followed by 12.5 mg/kg/h for 4 h),and a continuous infusion of 6.25 mg/h NAC plus 4 mg DEXA every 12 h for 48 h after cTACE.The placebo group received an infusion of 5%glucose solution until 48 h after procedure.PES was defined by South West Oncology Group toxicity code grading of more than 2 that was calculated using incidence of fever,nausea,vomiting,and pain.RESULTS One-hundred patients were enrolled with 50 patients in each group.Incidence of PES was significantly lower in the NAC+DEXA group compared with in the placebo group(6%vs 80%;P<0.001).Multivariate analysis showed that the dual treatment is a protective strategic therapy against PES development[odds ratio(OR)=0.04;95%confidence interval(CI):0.01-0.20;P<0.001).Seven(14%)patients in the placebo group,but none in the NAC+DEXA group,developed post-TACE liver decompensation.A dynamic change in Albumin-Bilirubin score of more than 0.5 point was found to be a risk factor for post-TACE liver decompensation(OR=42.77;95%CI:1.01-1810;P=0.049).CONCLUSION Intravenous NAC+DEXA administration ameliorated the occurrence of PES event after cTACE in patients with intermediate-stage HCC.

Development and validation of a prognostic nomogram for decompensated liver cirrhosis

BACKGROUND Decompensated liver cirrhosis(DLC)is a stage in the progression of liver cirrhosis and has a high mortality.AIM To establish and validate a novel and simple-to-use predictive nomogram for evaluating the prognosis of DLC patients.METHODS A total of 493 patients with confirmed DLC were enrolled from The First Affiliated Hospital of Nanchang University(Nanchang,Jiangxi Province,China)between December 2013 and August 2019.The patients were divided into two groups:a derivation group(n=329)and a validation group(n=164).Univariate and multivariate Cox regression analyses were performed to assess prognostic factors.The performance of the nomogram was determined by its calibration,discrimination,and clinical usefulness.RESULTS Age,mechanical ventilation application,model for end-stage liver disease(MELD)score,mean arterial blood pressure,and arterial oxygen partial pressure/inhaled oxygen concentration were used to construct the model.The Cindexes of the nomogram in the derivation and validation groups were 0.780(95%CI:0.670-0.889)and 0.792(95%CI:0.698-0.886),respectively.The calibration curve exhibited good consistency with the actual observation curve in both sets.In addition,decision curve analysis indicated that our nomogram was useful in clinical practice.CONCLUSION A simple-to-use novel nomogram based on a large Asian cohort was established and validated and exhibited improved performance compared with the Child-Turcotte-Pugh and MELD scores.For patients with DLC,the proposed nomogram may be helpful in guiding clinicians in treatment allocation and may assist in prognosis prediction.

Status epilepticus as an initial manifestation of hepatic encephalopathy:A case report

BACKGROUND Status epilepticus in patients with hepatic encephalopathy (HE) is a rare butserious condition that is refractory to antiepileptic drugs, and current treatmentplans are vague. Diagnosis may be difficult without a clear history of cirrhosis.Liver transplantation (LT) is effective to alleviate symptoms, however, there arefew reports about LT in the treatment of status epilepticus with HE. To ourknowledge, this is the first report of status epilepticus present as initialmanifestation of HE.CASE SUMMARY A 59-year-old woman with a 20-year history of heavy drinking was hospitalizedfor generalized tonic-clonic seizures. She reported no history of episodes of HE,stroke, spontaneous bacterial peritonitis, ascites or gastrointestinal bleeding.Neurological examination revealed a comatose patient, without papilledema.Laboratory examination suggested liver cirrhosis. Plasma ammonia levels uponadmission were five times normal. Brain computed tomography (CT) was normal,while abdominal CT and ultrasound revealed mild ascites, liver cirrhosis andsplenomegaly. Electroencephalography (EEG)showed diffuse slow waves rhythm,consistent with HE, and sharp waves during ictal EEG corresponding to clinicalsemiology of focal tonic seizures. The symptoms were reversed by continuousantiepileptic treatment and lactulose. She was given oral levetiracetam, and focalaware seizures occasionally affected her 10 mo after LT.CONCLUSION Status epilepticus could be an initial manifestation of HE. Antiepileptic drugs combined with lactulose are essential for treatment of status epilepticus with HE,and LT is effective to prevent the relapse.

Spontaneous Bacterial Peritonitis and Short-Term Prognosis in a Group of Decompensated Cirrhotic Patients in Yaounde: A Cross-Sectional Study

Introduction: Spontaneous bacterial peritonitis (SBP) is among the most common infections in cirrhotic patients. Data on SBP are rare in Cameroon. This prompted us to carry out this study on patients with decompensated cirrhosis of the liver in Yaounde University Hospital Centre (YUHC). Methods: We carried out a cross-sectional study from December 2015 to June 2016 in three units of YUHC. All patients with decompensated liver cirrhosis were included. Our sampling was consecutive. Diagnosis of cirrhosis was performed, based on clinical, biological and ultrasound criteria. A neutrophil count greater than 250 cell/mm3 in ascites fluid defined an SBP. Data on socio-demography, clinical presentation, and outcomes were collected. Results: We included 34 decompensated cirrhotic patients (15 males). Patients mean age was 57.5 ± 2 years (SBP positive: 48.7 ± 21.3 versus without SBP: 59.8 ± 19.5, p = 0.22). SBP diagnosis was made in 6 (17.7%) patients. Compared to patients with decompensated liver cirrhosis and without SBP, positive SBP patients had a higher pulse rate (p = 0.002) and respiratory rate (p = 0.02). The patients with SBP were more likely to present these other clinical features: pulse rate >100 (RR: 4.2, [95% CI: 0.7 - 27.7];p = 0.02), presence of jaundice (RR: 3.4, [95% CI: 0.6 - 21.1];p = 0.09), being from female gender (RR: 3.2, [95% CI: 0.5 - 19.9]; p = 0.11), advanced liver disease (Child C class) (RR: 2.4, [95% CI: 0.4 - 14.5], p = 0.66), low-plasma albumin (less than 20 g/L) (RR: 1.7, [95% CI: 0.8 - 3.9], p = 0.08), respiratory rate > 30 (RR: 1.6, [95% CI: 0.6 - 3.3], p = 0.05) and fever/hypothermia (RR: 1.5, [95% CI: 0.6 - 3.4];p = 0.22). Evolution after a 72-hours antibiotherapy was stationary in four cases and unfavorable in two patients, resulting in death. Conclusion: SBP prevalence was 17.7%. SBP patients were younger, from female sex, tachycardia and polypnea, presenting with fever/hypothermia and signs of advanced liver disease than non-SBP patients. Improvement of our technical platform will be useful to determine the cause of cirrhosis and identify the different germs responsible for SBP.

Plasma copeptin concentration is a predictor of tolvaptan efficacy in patients with hepatic ascites

Aims:No solid evidence-based opinion was raised regarding predictors of the degree of ascites reduction with tolvaptan.This retrospective cohort study aimed to examine whether serum copeptin concentration is a useful predictor of this.Methods:The study population consisted of 80 patients with liver cirrhosis treated with tolvaptan for hepatic ascites effusions at Nara Medical University Hospital from May 2014 to December 2018.Forty-three patients who lost>1.5 kg of body weight in the first week after starting tolvaptan were classified as good responders and the remaining 37 as poor responders.Various laboratory parameters were measured immediately before the start of tolvaptan therapy to examine factors associated with predicting its efficacy.Results:In the univariate analysis,no significant differences with respect to age(67.6 vs.69.8 years,p>0.05),sex,body mass index(24.8 vs.23.7 kg/m^(2),p>0.05),Child-Pugh score(9.4 vs.9.7,p>0.05),and Model for End-stage Liver Disease score(11 vs.12,p>0.05)were found between the two groups.Conversely,aspartate transferase and alanine transaminase(ALT)levels were significantly lower in the good response group(52.9±56.3 vs.68.8±50.7 U/L,p<0.05;26.2±30.6 vs.40.5±33.5 U/L,p<0.01),whereas serum copeptin and serum sodium concentrations were significantly higher(57.1±15.0 vs.45.8±16.0 pg/mL,p<0.01;136.3±3.4 vs.133.8±5.8 mEq/L,p<0.05).In the multivariate analysis,serum copeptin concentration and ALT were statistically significant factors(p<0.01,p<0.05).Regression analysis of the association between the tolvaptan efficacy for refractory ascites and pretreatment serum copeptin concentration showed that a copeptin concentration cutoff of 45.9 pg/mL could predict treatment efficacy with a sensitivity,specificity,and area under the curve of 76.7%,59.5%,and 0.71%,respectively.Conclusion:Serum copeptin concentration may be a predictor of tolvaptan efficacy for refractory ascites effusion in Japanese patients with liver cirrhosis.

Efficacy and feasibility of radiofrequency ablation for decompensated cirrhotic patients with hepatocellular carcinoma

Background Most HCC patients with decompensation of liver function lost the chance of surgical and/or interventional treatment. The aim of this study was to evaluate feasibility and outcome of radiofrequency ablation （RFA） in treating hepatocellular carcinoma （HCC） patients with poor liver function （Child-Pugh class C）, who are not suitable for surgery or hepatic artery chemo-embolization.Methods Thirteen HCC patients （the number of tumors was 17） with liver function of Child-Pugh C （scores： 10.2±0.4）were included in the study. Among the patients, 8 were male and 5 were female with the average age of （61.6±10.9）years old. The average size of HCC was （3.8±1.0） cm. Two patients were recurrent HCC and 30.8% of the patients had multiple tumors （2-3 tumors）. All the patients were treated with RFA.Results There were 22 RFA sessions （1-4 sessions per patient） in all, average ablations per tumor at first session was 3.1. One week after RFA, the liver enzymes elevated in 9 patients （69.2%）, in 7 of them, the liver enzyme returned to pre-RFA level in 1-3 months. One month after RFA, the Child-Pugh grading was 10.3±0.8 （Child-Pugh C）, while that of pre-RFA was 10.2±0.4 （Child-Pugh C）, with no significant difference. Computer tomography （CT） one month after RFA showed that the tumor necrosis rate was 88.2% （15/17）. Five patients had 2-4 repeated RFA due to HCC recurrence.During the follow-up of 2-69 months in this group, survival rate of one year was 53.8%, two years was 30.8%, and three year was 15.4%. The incidence of RFA-related complications was 13.6% （3/22 sessions）, including 1 case of GI hemorrhage and 1 sub-capsular hemorrhage of the liver. One patient with HCC over 5 cm who had fever and liver abscess after RFA, and was dead 2 months later due to liver function failure.Conclusions Minimal invasive RFA provides possible treatment modality for HCC patients with poor liver function, who are not candidates for surgical and/or interventional therapy. For large HCC, due to the required extended treatment region, special attention should be paid to the possibility of acute liver failure.
