Clinical study on the relationship between liver cirrhosis,ascites,and hyponatremia

BACKGROUND Cirrhosis is a common liver disease,and ascites is one of the common clinical conditions.However,the clinical manifestations of ascites combined with hyponatremia as a high-risk condition and its relationship to patient prognosis have not been fully studied.AIM To explore the clinical manifestations,prognostic factors,and relationships of ascites with hyponatremia in patients with cirrhosis to provide better diagnostic and treatment strategies.METHODS In this study,we retrospectively analyzed the clinical data of 150 patients diagnosed with cirrhosis and ascites between 2017 and 2022.Patients were divided into two groups:ascites combined with hyponatremia group and ascites group.We compared the general characteristics,degree of hyponatremia,complications,treatment,and prognosis between the two groups.RESULTS In the study results,patients in the ascites combined with hyponatremia group showed an older average age(58.2±8.9 years),64.4%were male,and had a significantly longer hospitalization time(12.7±5.3 d).Hyponatremia was more severe in this group,with a mean serum sodium concentration of 128.5±4.3 mmol/L,which was significantly different from the ascites group of 137.6±2.1 mmol/L.Patients with ascites and hyponatremia were more likely to develop hepatic encephalopathy(56.2%vs 39.0%),renal impairment(45.2%vs 28.6%)and infection(37.0%vs 23.4%).Regarding treatment,this group more frequently used diuretics(80.8%vs 62.3%)and salt supplements(60.3%vs 38.9%).Multiple logistic regression analysis identified older age[Odds ratio(OR)=1.06,P=0.025]and male gender(OR=1.72,P=0.020)as risk factors for hyponatremia combined with ascites.Overall,patients with ascites and hyponatremia present a clear high-risk status,accompanied by severe complications and poor prognosis.CONCLUSION In patients with cirrhosis,ascites with hyponatremia is a high-risk condition that is often associated with severe complications.

Changes in the etiology of liver cirrhosis and the corresponding management strategies

We read with interest the article by Xing Wang,which was published in the recent issue of the World Journal of Hepatology 2023;15:1294-1306.This article focuses particularly on the prevalence and trends in the etiology of liver cirrhosis(LC),prognosis for patients suffering from cirrhosis-related complications and hepatocellular carcinoma(HCC),and management strategies.The etiology of cirrhosis varies according to geographical,economic,and population factors.Viral hepatitis is the dominant cause in China.Vaccination and effective treatment have reduced the number of people with viral hepatitis,but the overall number is still large.Patients with viral hepatitis who progress over time to LC and HCC remain an important population to manage.The increased incidence of metabolic syndrome and alcohol consumption is likely to lead to a potential exponential increase in metabolic dysfunction-associated steatotic liver disease(MASLD)-associated LC and alcoholic liver disease in the future.Investigating the evolution of the etiology of LC is important for guiding the direction of future research and policy development.These changing trends indicate a need for greater emphasis on tackling obesity and diabetes,and implementing more effective measures to regulate alcohol consumption in order to reduce the occurrence of MASLD.In an effort to help cope with these changing trends,the authors further proposed countermeasures for healthcare authorities doctors,and patients.

Development and validation of a nomogram for predicting in-hospital mortality of intensive care unit patients with liver cirrhosis

BACKGROUND Liver cirrhosis patients admitted to intensive care unit(ICU)have a high mortality rate.AIM To establish and validate a nomogram for predicting in-hospital mortality of ICU patients with liver cirrhosis.METHODS We extracted demographic,etiological,vital sign,laboratory test,comorbidity,complication,treatment,and severity score data of liver cirrhosis patients from the Medical Information Mart for Intensive Care IV(MIMIC-IV)and electronic ICU(eICU)collaborative research database(eICU-CRD).Predictor selection and model building were based on the MIMIC-IV dataset.The variables selected through least absolute shrinkage and selection operator analysis were further screened through multivariate regression analysis to obtain final predictors.The final predictors were included in the multivariate logistic regression model,which was used to construct a nomogram.Finally,we conducted external validation using the eICU-CRD.The area under the receiver operating characteristic curve(AUC),decision curve,and calibration curve were used to assess the efficacy of the models.RESULTS Risk factors,including the mean respiratory rate,mean systolic blood pressure,mean heart rate,white blood cells,international normalized ratio,total bilirubin,age,invasive ventilation,vasopressor use,maximum stage of acute kidney injury,and sequential organ failure assessment score,were included in the multivariate logistic regression.The model achieved AUCs of 0.864 and 0.808 in the MIMIC-IV and eICU-CRD databases,respectively.The calibration curve also confirmed the predictive ability of the model,while the decision curve confirmed its clinical value.CONCLUSION The nomogram has high accuracy in predicting in-hospital mortality.Improving the included predictors may help improve the prognosis of patients.

Contemporary concepts of prevention and management of gastroesophageal variceal bleeding in liver cirrhosis patients

This editorial describes the contemporary concepts of prevention and management of gastroesophageal variceal bleeding in liver cirrhosis(LC)patients according to the current guidelines.Gastroesophageal variceal bleeding is the most dangerous complication of portal hypertension in LC patients.Risk stratification and determination of an individual approach to the choice of therapeutic measures aimed at their prevention and management has emerged as one of the top concerns in modern hepatology.According to the current guidelines,in the absence of clinically significant portal hypertension,etiological and nonetiological therapies of LC is advisable for the primary preventing gastroesophageal variceal bleeding,whereas its presence serves as an indication for the administration of non-selectiveβ-blockers,among which carvedilol is the drug of choice.Non-selectiveβ-blockers,as well as endoscopic variceal ligation and transjugular intrahepatic portosystemic shunt can be used to prevent recurrence of gastroesophageal variceal bleeding.Pharmacotherapy with vasoactive drugs(terlipressin,somatostatin,octreotide),endoscopic variceal ligation,endovascular techniques and transjugular intrahepatic portosystemic shunt are recommended for the treatment of acute gastroesophageal variceal bleeding.Objective and accurate risk stratification of gastroesophageal variceal bleeding will allow developing individual strategies for their prevention and management,avoiding the first and further decompensation in LC,which will improve the prognosis and survival of patients suffering from it.

Causal association between 731 immunocyte phenotypes and liver cirrhosis: A bidirectional two-sample mendelian randomization analysis

BACKGROUND Liver cirrhosis is a progressive hepatic disease whose immunological basis has attracted increasing attention.However,it remains unclear whether a concrete causal association exists between immunocyte phenotypes and liver cirrhosis.AIM To explore the concrete causal relationships between immunocyte phenotypes and liver cirrhosis through a mendelian randomization(MR)study.METHODS Data on 731 immunocyte phenotypes were obtained from genome-wide assoc-iation studies.Liver cirrhosis data were derived from the Finn Gen dataset,which included 214403 individuals of European ancestry.We used inverse variable weighting as the primary analysis method to assess the causal relationship.Sensitivity analyses were conducted to evaluate heterogeneity and horizontal pleiotropy.RESULTS The MR analysis demonstrated that 11 immune cell phenotypes have a positive association with liver cirrhosis[P<0.05,odds ratio(OR)>1]and that 9 immu-nocyte phenotypes were negatively correlated with liver cirrhosis(P<0.05,OR<1).Liver cirrhosis was positively linked to 9 immune cell phenotypes(P<0.05,OR>1)and negatively linked to 10 immune cell phenotypes(P<0.05;OR<1).None of these associations showed heterogeneity or horizontally pleiotropy(P>0.05).CONCLUSION This bidirectional two-sample MR study demonstrated a concrete causal association between immunocyte phenotypes and liver cirrhosis.These findings offer new directions for the treatment of liver cirrhosis.

Fat necrosis of liver in a patient with mixed type liver cirrhosis

To the Editor: Fatty liver diseases, including nonalcoholic fatty liver disease and alcohol related fatty liver disease, have become a major public health concern [ 1, 2 ]. Fatty liver diseases have been shown to progress through various stages, from steatosis or necrosis with inflammation and hepatocyte damage to the development of fibrosis and eventual cirrhosis with an increased risk of carcinoma [ 2, 3 ].

Diagnosis and Management of Biliary Strictures after Deceased-Donor Liver Transplantation Based on Clinical Practice

Biliary complications are still the main complications for liver transplantation recipients. Biliary strictures comprise the major part of all biliary complications after deceased-donor liver transplantation (LT). Biliary strictures following LT are divided into anastomotic strictures (AS) and non-anastomotic strictures (NAS). A Limitation of current published researches is that most studies aren’t based on clinical practice. The aim of this review is to summarize risk factors, clinical presentation, diagnosis and management in post-LT biliary strictures.

Primary liver transplantation vs transplant after Kasai portoenterostomy in children with biliary atresia: A retrospective Brazilian single-center cohort

BACKGROUND Biliary atresia(BA)is the most common indication for pediatric liver transplantation,although portoenterostomy is usually performed first.However,due to the high failure rate of portoenterostomy,liver transplantation has been advocated as the primary procedure for patients with BA.It is still unclear if a previous portoenterostomy has a negative impact on liver transplantation outcomes.AIM To investigate the effect of prior portoenterostomy in infants un-dergoing liver transplantation for BA.METHODS This was a retrospective cohort study of 42 pediatric patients with BA who underwent primary liver transplantation from 2013 to 2023 at a single tertiary center in Brazil.Patients with BA were divided into two groups:Those undergoing primary liver transplantation without portoenterostomy and those undergoing liver transplantation with prior portoenterostomy.Continuous variables were compared using the Student’s t-test or the Kruskal-Wallis test,and categorical variables were compared using theχ2 or Fisher’s exact test,as appropriate.Multivariable Cox regression analysis was performed to determine risk factors for portal vein thrombosis.Patient and graft survival analyses were conducted with the Kaplan–Meier product-limit estimator,and patient subgroups were compared using the two-sided log-rank test.RESULTS Forty-two patients were included in the study(25[60%]girls),23 undergoing liver transplantation without prior portoenterostomy,and 19 undergoing liver transplantation with prior portoenterostomy.Patients with prior portoenterostomy were older(12 vs 8 months;P=0.02)at the time of liver transplantation and had lower Pediatric End-Stage Liver Disease scores(13.2 vs 21.4;P=0.01).The majority of the patients(35/42,83%)underwent livingdonor liver transplantation.The group of patients without prior portoenterostomy appeared to have a higher incidence of portal vein thrombosis(39 vs 11%),but this result did not reach statistical significance.Prior portoenterostomy was not a protective factor against portal vein thrombosis in the multivariable analysis after adjusting for age at liver transplantation,graft-to-recipient weight ratio,and use of vascular grafts.Finally,the groups did not significantly differ in terms of post-transplant survival.CONCLUSION In our study,prior portoenterostomy did not significantly affect the outcomes of liver transplantation.

Endoscopic ultrasound-guided biliary drainage vs percutaneous transhepatic bile duct drainage in the management of malignant obstructive jaundice

BACKGROUND Malignant obstructive jaundice(MOJ)is a condition characterized by varying degrees of bile duct stenosis and obstruction,accompanied by the progressive development of malignant tumors,leading to high morbidity and mortality rates.Currently,the two most commonly employed methods for its management are percutaneous transhepatic bile duct drainage(PTBD)and endoscopic ultrasound-guided biliary drainage(EUS-BD).While both methods have demonstrated favorable outcomes,additional research needs to be performed to determine their relative efficacy.To compare the therapeutic effectiveness of EUS-BD and PTBD in treating MOJ.METHODS This retrospective analysis,conducted between September 2015 and April 2023 at The Third Affiliated Hospital of Soochow University(The First People’s Hospital of Changzhou),involved 68 patients with MOJ.The patients were divided into two groups on the basis of surgical procedure received:EUS-BD subgroup(n=33)and PTBD subgroup(n=35).Variables such as general data,preoperative and postoperative indices,blood routine,liver function indices,myocardial function indices,operative success rate,clinical effectiveness,and complication rate were analyzed and compared between the subgroups.RESULTS In the EUS-BD subgroup,hospital stay duration,bile drainage volume,effective catheter time,and clinical effect-iveness rate were superior to those in the PTBD subgroup,although the differences were not statistically significant(P>0.05).The puncture time for the EUS-BD subgroup was shorter than that for the PTBD subgroup(P<0.05).Postoperative blood routine,liver function index,and myocardial function index in the EUS-BD subgroup were significantly lower than those in the PTBD subgroup(P<0.05).Additionally,the complication rate in the EUS-BD subgroup was lower than in the PTBD subgroup(P<0.05).CONCLUSION EUS-BD may reduce the number of punctures,improve liver and myocardial functions,alleviate traumatic stress,and decrease complication rates in MOJ treatment.

Branched chain amino acids in hepatic encephalopathy and sarcopenia in liver cirrhosis:Evidence and uncertainties

Liver cirrhosis is commonly associated with nutritional alterations,reported in 20% of patients with compensated disease and over 60% of patients with decompensated cirrhosis.Nutritional disturbances are associated with a worse prognosis and increased risk of complication.Serum levels of branched-chain amino acids(BCAAs)are decreased in patients with liver cirrhosis.The imbalance of amino acids levels has been suggested to be associated with the development of complications,such as hepatic encephalopathy and sarcopenia,and to affect the clinical presentation and prognosis of these patients.Several studies investigated the efficacy of BCAAs supplementation as a therapeutic option in liver cirrhosis,but uncertainties remain about the real efficacy,the best route of administration,and dosage.

Therapeutic possibilities of gut microbiota modulation in acute decompensation of liver cirrhosis

The formation of liver cirrhosis(LC) is an unfavorable event in the natural history of chronic liver diseases and with the development of portal hypertension and/or impaired liver function can cause a fatal outcome. Decompensation of LC is considered the most important stratification variable for the risk of death. It is currently postulated that decompensation of LC occurs through an acute(including acute-on-chronic liver failure) and non-acute pathway. Acute decompensation of LC is accompanied by the development of life-threatening complications, characterized by an unfavorable prognosis and high mortality.Progress in understanding the underlying molecular mechanisms has led to the search for new interventions, drugs, and biological substances that can affect key links in the pathogenesis of acute decompensation in LC, for example the impaired gut-liver axis and associated systemic inflammation. Given that particular alterations in the composition and function of gut microbiota play a crucial role here, the study of the therapeutic possibilities of its modulation has emerged as one of the top concerns in modern hepatology. This review summarized the investigations that describe the theoretical foundations and therapeutic potential of gut microbiota modulation in acute decompensation of LC. Despite the encouraging preliminary data, the majority of the suggested strategies have only been tested in animal models or in preliminary clinical trials;additional multicenter randomized controlled trials must demonstrate their efficacy in larger patient populations.

Study of liver cirrhosis over twenty consecutive years in adults in Southern China

BACKGROUND Liver cirrhosis(LC)is a prevalent and severe disease in China.The burden of LC is changing with widespread vaccination of hepatitis B virus(HBV)and antiviral therapy.However,the recent transition in etiologies and clinical features of LC cases requiring hospitalization is unclear.AIM To identify the transition in etiologies and clinical characteristics of hospitalized LC patients in Southern China.METHODS In this retrospective,cross-sectional study we included LC inpatients admitted between January 2001 and December 2020.Medical data indicating etiological diagnosis and LC complications,and demographic,laboratory,and imaging data were collected from our hospital-based dataset.The etiologies of LC were mainly determined according to the discharge diagnosis,and upper gastrointestinal bleeding,ascites,hepatic encephalopathy,spontaneous bacterial peritonitis,hepatocellular carcinoma(HCC),portal vein thrombosis,hepatorenal syndrome,and acute-on-chronic liver failure(ACLF)were considered LC-related complications in our study.Changing trends in the etiologies and clinical characteristics were investigated using logistic regression,and temporal trends in proportions of separated years were investigated using the Cochran-Armitage test.In-hospital prognosis and risk factors associated with in-hospital mortality were also invest igated.RESULTS A total of 33143 patients were included in the study[mean(SD)age,51.7(11.9)years],and 82.2%were males.The mean age of the study population increased from 51.0 years in 2001-2010 to 52.0 years in 2011-2020(P<0.001),and the proportion of female patients increased from 16.7%in 2001-2010 to 18.2%in 2011-2020(P=0.003).LC patients in the decompensated stage at diagnosis decreased from 68.1%in 2001-2010 to 64.6%in 2011-2020(P<0.001),and the median score of model for end-stage liver disease also decreased from 14.0 to 11.0(P<0.001).HBV remained the major etiology of LC(75.0%)and the dominant cause of viral hepatitis-LC(94.5%)during the study period.However,the proportion of HBV-LC decreased from 82.4%in 2001-2005 to 74.2%in 2016-2020,and the proportion of viral hepatitis-LC decreased from 85.2%in 2001-2005 to 78.1%in 2016-2020(both P for trend<0.001).Meanwhile,the proportions of LC caused by alcoholic liver disease,autoimmune hepatitis and mixed etiology increased by 2.5%,0.8%and 4.5%,respectively(all P for trend<0.001).In-hospital mortality was stable at 1.0%in 2011-2020,whereas HCC and ACLF manifested the highest increases in prevalence among all LC complications(35.8%to 41.0%and 5.7%to 12.4%,respectively)and were associated with 6-fold and 4-fold increased risks of mortality(odds ratios:6.03 and 4.22,respectively).CONCLUSION LC inpatients have experienced changes in age distribution and etiologies of cirrhosis over the last 20 years in Southern China.HCC and ACLF are associated with the highest risk of in-hospital mortality among LC complications.

Machine perfusion and the prevention of ischemic type biliary lesions following liver transplant:What is the evidence?

The widespread uptake of different machine perfusion(MP)strategies for liver transplant has been driven by an effort to minimize graft injury.Damage to the cholangiocytes during the liver donation,preservation,or early posttransplant period may result in stricturing of the biliary tree and inadequate biliary drainage.This problem continues to trouble clinicians,and may have catastrophic consequences for the graft and patient.Ischemic injury,as a result of compromised hepatic artery flow,is a well-known cause of biliary strictures,sepsis,and graft failure.However,very similar lesions can appear with a patent hepatic artery and these are known as ischemic type biliary lesions(ITBL)that are attributed to microcirculatory dysfunction rather than main hepatic arterial compromise.Both the warm and cold ischemic period duration appear to influence the onset of ITBL.All of the commonly used MP techniques deliver oxygen to the graft cells,and therefore may minimize the cholangiocyte injury and subsequently reduce the incidence of ITBL.As clinical experience and published evidence grows for these modalities,the impact they have on ITBL rates is important to consider.In this review,the evidence for the three commonly used MP strategies(abdominal normothermic regional perfusion[A-NRP],hypothermic oxygenated perfusion[HOPE],and normothermic machine perfusion[NMP])for ITBL prevention has been critically reviewed.Inconsistencies with ITBL definitions used in trials,coupled with variations in techniques of MP,make interpretation challenging.Overall,the evidence suggests that both HOPE and A-NRP prevent ITBL in donated after circulatory death grafts compared to cold storage.The evidence for ITBL prevention in donor after brain death grafts with any MP technique is weak.

Racial and gender-based disparities and trends in common psychiatric conditions in liver cirrhosis hospitalizations:A ten-year United States study

BACKGROUND Chronic liver disease is associated with various neuropsychiatric conditions.There are currently no large studies assessing and comparing the prevalence of psy-chiatric illnesses based on patient profiles and the etiology of cirrhosis.AIM To examine the trends of hospitalizations among psychiatric conditions in cirrhosis.METHODS We used the National Inpatient Sample database 2016-2019 for the primary diagnosis of liver cirrhosis.The outcomes included the prevalence,trends,and associations of psychiatric diagnoses in these hospitalizations.Chi-square for categorical variables and the Wilcoxon rank test for continuous variables were utilized.RESULTS The prevalence of generalized anxiety disorder(GAD)in liver cirrhosis hospitalizations increased from 0.17%in 2009 to 0.92%in 2019(P<0.001).The prevalence of depression increased from 7%in 2009 to 12%in 2019(P<0.001).Attention deficit hyperactivity disorder(ADHD)prevalence increased from 0.06%to 0.24%.The prevalence of schizophrenia increased from 0.59%to 0.87%(P<0.001).Schizoaffective disorder prevalence increased from 0.10%to 0.35%(P<0.001).Posttraumatic stress disorder(PTSD)prevalence displayed increasing trends from 0.36%in 2009 to 0.93%in 2019(P<0.001).The prevalence of suicidal ideation increased from 0.23%to 0.56%in 2019.Cirrhosis related to alcoholic liver disease[adjusted odds ratios(aOR)1.18,95%CI 1.08-1.29,P<0.001]and non-alcoholic fatty liver disease(NAFLD)(aOR 1.14,95%CI 1.01-1.28,P=0.025)was associated with depression more than other causes.Alcohol-and NAFLD-associated cirrhosis had a stronger link to psychiatric disorders.Females had a higher association with GAD(aOR 2.56,95%CI 2.14-3.06,P<0.001),depression(aOR 1.78,95%CI 1.71-1.84,P<0.001),bipolar disorder(aOR 1.64,95%CI 1.52-1.77,P<0.001]and chronic fatigue(aOR 2.31,95%CI 1.31-4.07,P<0.001)when compared to males.Blacks,Hispanics,and Asian/Native Americans had a significantly lower association with GAD,depression,bipolar disorder,PTSD,and ADHD when compared to the white race.CONCLUSION The prevalence of psychiatric comorbidities in liver cirrhosis hospitalizations has increased over the last decade.Females had a higher association with psychiatric disorders compared to males.Blacks,Hispanics,and Asian/Native Americans had lower associations with psychiatric comorbidities compared to the white race.

Difference and clinical value of metabolites in plasma and feces of patients with alcohol-related liver cirrhosis

BACKGROUND Alterations in plasma and intestinal metabolites contribute to the pathogenesis and progression of alcohol-related liver cirrhosis(ALC).AIM To explore the common and different metabolites in the plasma and feces of patients with ALC and evaluate their clinical implications.METHODS According to the inclusion and exclusion criteria,27 patients with ALC and 24 healthy controls(HCs)were selected,and plasma and feces samples were collected.Liver function,blood routine,and other indicators were detected with automatic biochemical and blood routine analyzers.Liquid chromatography-mass spectrometry was used to detect the plasma and feces metabolites of the two groups and the metabolomics of plasma and feces.Also,the correlation between metabolites and clinical features was analyzed.RESULTS More than 300 common metabolites were identified in the plasma and feces of patients with ALC.Pathway analysis showed that these metabolites are enriched in bile acid and amino acid metabolic pathways.Compared to HCs,patients with ALC had a higher level of glycocholic acid(GCA)and taurocholic acid(TCA)in plasma and a lower level of deoxycholic acid(DCA)in the feces,while L-threonine,L-phenylalanine,and L-tyrosine increased simultaneously in plasma and feces.GCA,TCA,L-methionine,L-phenylalanine,and L-tyrosine in plasma were positively correlated with total bilirubin(TBil),prothrombin time(PT),and maddrey discriminant function score(MDF)and negatively correlated with cholinesterase(CHE)and albumin(ALB).The DCA in feces was negatively correlated with TBil,MDF,and PT and positively correlated with CHE and ALB.Moreover,we established a P/S BA ratio of plasma primary bile acid(GCA and TCA)to fecal secondary bile acid(DCA),which was relevant to TBil,PT,and MDF score.CONCLUSION The enrichment of GCA,TCA,L-phenylalanine,L-tyrosine,and L-methionine in the plasma of patients with ALC and the reduction of DCA in feces were related to the severity of ALC.These metabolites may be used as indicators to evaluate the progression of alcohol-related liver cirrhosis.

A Case of Acute Upper Gastrointestinal Bleeding in Liver Cirrhosis Complicated by Acute Cerebral Infarction and Acute Myelitis

Background: Acute upper gastrointestinal bleeding in liver cirrhosis combined with acute cerebral infarction is uncommon in clinical work, and then combined with acute myelitis is even rarer and more complex, which poses a greater challenge to clinical diagnosis and treatment. This paper reports a case of acute upper gastrointestinal bleeding in liver cirrhosis complicated by acute cerebral infarction and acute myelitis, which be hoped to provide a reference for clinical work. Methods: We retrospectively evaluated the clinical information of a 68-year-old female admitted to the Digestive Medical Department with acute gastrointestinal bleeding and appeared limb movement disorder on the third day. Results: The patient was eventually diagnosed with acute upper gastrointestinal bleeding in liver cirrhosis complicated by acute cerebral infarction and acute myelitis. Conclusions: When patients with liver cirrhosis have abnormal neurological symptoms, in addition to liver cirrhosis-related complications, doctors need to consider cerebrovascular diseases and myelitis.

Evaluation of the nutritional status of patients with liver cirrhosis

BACKGROUND Progressive malnutrition coexists with liver diseases,particularly in patients with cirrhosis.Early diagnosis of malnutrition in patients with advanced stages of chronic liver disease and the implementation of appropriate nutritional treatment for malnourished patients should be an integral part of the therapeutic process.AIM To evaluate the nutritional status of patients with various severities of advanced liver fibrosis,using various nutritional status parameters.METHODS This study involved 118 patients with liver cirrhosis who were classified into three groups according to their Child-Pugh score.The nutritional status of the patients in each group was assessed using different methods.The average values obtained from the measurements were calculated for each research group.The influence of disease stage on the examined parameters of nutritional status was determined using one-way analysis of variance.To investigate the relationship between the parameters determining nutritional status and the stage of disease advancement,a correlation analysis was performed.RESULTS The Child-Pugh A group had the highest mean body weight(76.42 kg),highest mean body mass index(BMI)(26.72 kg/m²),and largest mean arm circumference(27.64 cm).In the Child-Pugh B group,the mean scores of all examined variables were lower than those of the Child-Pugh A group,whereas the mean body weight and BMI of the Child-Pugh C group were higher than those of the Child-Pugh B group.There was a very strong correlation between the Child-Pugh classification and subjective global assessment score;a very strong correlation between the Child-Pugh classification and arm circumference;a strong correlation between the Child-Pugh classification and body weight,albumin concentration,fat-free mass index,muscle mass index,phase angle,and BMI;and an average correlation between Child-Pugh classification and fat mass index.Notably,these indicators deteriorated with disease progression.CONCLUSION Advanced liver fibrosis leads to the deterioration of many nutritional status parameters.The extent of malnutrition increases with the progression of liver fibrosis.The Child-Pugh score reflects the nutritional status.

Risk Factors of Liver Cirrhosis in Chad: Large Proportion of Cases without Clear Etiology

Background: In comparison to other forms of chronic liver diseases, cirrhosis is generally poorly studied in sub Saharan Africa. In Chad, more particularly, no data are available despite the burden of liver diseases considered as the first cause of hospitalizations in the country. Methods: We conducted a retrospective analysis of 268 patients with liver cirrhosis attending care at the University Reference Hospital between 2007 and 2016. Results: This series of liver cirrhoses was characterized by a weak mal predominance (M:F = 1.7). The age of onset occurs significantly earlier in women than in men (40.6 ± 12.0 vs. 44.4 ± 13.4, p = 0.0171). The principal risk factor was persistent infection with hepatitis B virus (49% of cases) followed distantly by infection with hepatitis C virus (13%) and excessive alcohol consumption (10%). Men were more frequently carrying HBV surface antigen than women (65.6% vs 35.9% p = 0.0019). HBV-associated liver cirrhosis was overall more severe than diseases from other causes. A large proportion of cirrhosis (30%), observed primarily in women (48.1% vs 24.1%, p = 0.0036), was considered are cryptogenic. Conclusions: The etiological spectrum of liver cirrhosis remains to be properly defined in Chad. This lack of knowledge prevents the implementation of an efficient policy of prevention. A significant effort should be secured to characterize hitherto neglected infectious, lifestyle or genetic risk factors responsible of this form of terminal disease and improve subsequently liver health of local populations.

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.

Molecular Mechanism of Zhizi Ganjiang Decoction in Regulating Liver Cirrhosis Based on BATMAN-TCM Platform

[Objectives]To explore the molecular mechanism of Zhizi Ganjiang Decoction in the treatment of liver cirrhosis based on the network pharmacology.[Methods]The BATMAN-TCM server was used to predict the potential targets of Zhizi Ganjiang Decoction,and the GeneCards database searched for targets related to liver cirrhosis;Cytoscape 3.5.1 software was used to construct compound-cirrhosis target interaction network and protein interaction network;then gene ontology(GO)enrichment analysis,Reactome pathway enrichment analysis,and KEGG-based biological pathway enrichment analysis were performed.[Results]The compound-disease-target network of Zhizi Ganjiang Decoction was constructed.The PPI network of Zhizi Ganjiang Decoction targets constructed based on String contained 130 nodes and 689 interaction relationships.The key nodes mainly involved nuclear hormone receptor-like domain superfamily and ligand binding domain,serpentine type 7TM GPCR chemoreceptor and chemoreceptor Srx,rhodopsin family transmembrane receptors,zinc finger NHR/GATA type nuclear hormone receptors and ligand binding domains,PI3-kinase family p85 binding domain,phosphoinositide(PI)3-kinase catalytic domain and other categories.GO enrichment analysis pathway related entries mainly involved steroid hormone receptor activity,nuclear receptor activity,transcription factor activity,direct ligands regulation sequence-specific DNA binding,G protein-coupled amine receptor activity,steroid binding,catecholamine binding,neurotransmitter receptor activity,adrenergic receptor activity,ammonium ion binding,and oxidoreductase activity,etc.KEGG channel analysis mainly involved neuroactive ligand-receptor interaction,aldosterone regulates sodium reabsorption,regulates lipolysis in adipocytes,regulates inflammatory mediators of TRP channels,tyrosine metabolism,calcium signaling pathway,cAMP signaling pathway,and nonalcoholic fatty liver diseases.[Conclusions]The research results suggest that Zhizi Ganjiang Decoction regulates the process of liver cirrhosis mainly through aldosterone regulation of sodium reabsorption,regulation of lipolysis in adipocytes,regulation of inflammatory mediators of TRP channels,calcium signaling pathways,and nonalcoholic fatty liver diseases.This reflects the multi-target and holistic action characteristics of the Chinese herbal compounds,and is expected to provide new ideas for further research on the molecular mechanism of Zhizi Ganjiang Decoction.
