Hepatocardiorenal syndrome in liver cirrhosis:Recognition of a new entity?

Emerging evidence and perspectives have pointed towards the heart playing an important role in hepatorenal syndrome(HRS),outside of conventional understanding that liver cirrhosis is traditionally considered the sole origin of a cascade of pathophysiological mechanisms directly affecting the kidneys in this context.In the absence of established heart disease,cirrhotic cardiomyopathy may occur more frequently in those with liver cirrhosis and kidney disease.It is a specific form of cardiac dysfunction characterized by blunted contractile responsiveness to stress stimuli and altered diastolic relaxation with electrophysiological abnormalities.Despite the clinical description of these potential cardiac-related complications of the liver,the role of the heart has traditionally been an overlooked aspect of circulatory dysfunction in HRS.Yet from a physiological sense,temporality(prior onset)of cardiorenal interactions in HRS and positive effects stemming from portosystemic shunting demonstrated an important role of the heart in the development and progression of kidney dysfunction in cirrhotic patients.In this review,we discuss current concepts surrounding how the heart may influence the development and progression of HRS,and the role of systemic inflammation and endothelial dysfunction causing circulatory dysfunction within this setting.The temporality of heart and kidney dysfunction in HRS will be discussed.For a subgroup of patients who receive portosystemic shunting,the dynamics of cardiorenal interactions following treatment is reviewed.Continued research to determine the unknowns in this topic is anticipated,hopefully to further clarify the intricacies surrounding the liver-heart-kidney connection and improve strategies for management.

Optimizing nutrition in hepatic cirrhosis:A comprehensive assessment and care approach

Cirrhosis is considered a growing cause of morbidity and mortality,which represents a significant public health problem.Currently,there is no effective treatment to reverse cirrhosis.Treatment primarily centers on addressing the underlying liver condition,monitoring,and managing portal hypertension-related complications,and evaluating the potential for liver transplantation in cases of decompensated cirrhosis,marked by rapid progression and the emer-gence of complications like variceal bleeding,hepatic encephalopathy,ascites,malnutrition,and more.Malnutrition,a prevalent complication across all disease stages,is often underdiagnosed in cirrhosis due to the complexities of nutritional assessment in patients with fluid retention and/or obesity,despite its crucial impact on prognosis.Increasing emphasis has been placed on the collaboration of nutritionists within hepatology and Liver transplant teams to deliver compre-hensive care,a practice that has shown to improve outcomes.This review covers appropriate screening and assessment methods for evaluating the nutritional status of this population,diagnostic approaches for malnutrition,and context-specific nutrition treatments.It also discusses evidence-based recommendations for supplementation and physical exercise,both essential elements of the standard care provided to cirrhotic patients.

Quick and easy assessment of sarcopenia in cirrhosis: Can ultrasound be the solution?

Cirrhosis is frequently associated with sarcopenia,with reported rates of over 80%in patients with decompensated alcohol-related liver disease.Sarcopenia nega-tively impacts the prognosis of cirrhotic patients and affects the response to treatment of patients with hepatocellular carcinoma(HCC).For these reasons,identifying an easy-to-perform method to assess sarcopenia in is a key element in the optimization of care in this patient population.Assessment of muscle mass by computed tomography is considered the standard of care for the diagnosis of sarcopenia,but exposure to radiation and high costs limit its application in this setting,especially for repeated assessments.We believe that ultrasound,a cheap and harmless technique also used for HCC screening in cirrhotic patients,could have an expanding role in the diagnosis and follow-up of sarcopenia in these patients.

From liver to hormones:The endocrine consequences of cirrhosis

Hepatocrinology explores the intricate relationship between liver function and the endocrine system.Chronic liver diseases such as liver cirrhosis can cause endocrine disorders due to toxin accumulation and protein synthesis disruption.Despite its importance,assessing endocrine issues in cirrhotic patients is frequently neglected.This article provides a comprehensive review of the epidemiology,pathophysiology,diagnosis,and treatment of endocrine disturbances in liver cirrhosis.The review was conducted using the PubMed/Medline,EMBASE,and Scielo databases,encompassing 172 articles.Liver cirrhosis is associated with endocrine disturbances,including diabetes,hypoglycemia,sarcopenia,thyroid dysfunction,hypogonadotropic hypogonadism,bone disease,adrenal insufficiency,growth hormone dysfunction,and secondary hyperaldosteronism.The optimal tools for diagnosing diabetes and detecting hypoglycemia are the oral glucose tolerance test and continuous glucose monitoring system,respectively.Sarcopenia can be assessed through imaging and functional tests,while other endocrine disorders are evaluated using hormonal assays and imaging studies.Treatment options include metformin,glucagon-like peptide-1 analogs,sodium-glucose co-transporter-2 inhibitors,and insulin,which are effective and safe for diabetes control.Established standards are followed for managing hypoglycemia,and hormone replacement therapy is often necessary for other endocrine dysfunctions.Liver transplantation can address some of these problems.

Chronic hepatitis B virus infection in Eastern Ethiopia:Clinical characteristics and determinants of cirrhosis

BACKGROUND Chronic hepatitis B(CHB)virus infection is a major cause of liver-associated morbidity and mortality,particularly in low-income countries.A better understanding of the epidemiological,clinical,and virological characteristics of CHB will guide appropriate treatment strategies and improve the control and management of CHB in Ethiopia.AIM To investigate the characteristics of CHB in Eastern Ethiopia and assess the efficacy and safety of antiviral treatment.METHODS This cohort study included 193 adults who were human immunodeficiency virus-negative with CHB between June 2016 and December 2019.Baseline assessments included chemistry,serologic,and viral markers.χ^(2) tests,Mann-Whitney U tests,and logistic regression analyses were used to identify the determinants of cirrhosis.Tenofovir disoproxil fumarate(TDF)was initiated using treatment criteria from the Ethiopian CHB pilot program.RESULTS A total of 132 patients(68.4%)were men,with a median age of 30 years[interquartile range(IQR):24-38].At enrollment,60(31.1%)patients had cirrhosis,of whom 35(58.3%)had decompensated cirrhosis.Khat use,hepatitis B envelope antigen positivity,and a high viral load were independently associated with cirrhosis.Additionally,66 patients(33.4%)fulfilled the treatment criteria and 59(30.6%)started TDF.Among 29 patients who completed 24 months of treatment,the median aspartate aminotransferase to platelet ratio index declined from 1.54(IQR:0.66-2.91)to 1.10(IQR:0.75-2.53)(P=0.002),and viral suppression was achieved in 80.9%and 100%of patients after 12 months and 24 months of treatment,respectively.Among the treated patients,12(20.3%)died within the first 6 months of treatment,of whom 8 had decompensated cirrhosis.CONCLUSION This study highlights the high prevalence of cirrhosis,initial mortality,and the efficacy of TDF treatment.Scaling up measures to prevent and control CHB infections in Ethiopia is crucial.

Renal resistive index measurements by ultrasound in patients with liver cirrhosis:Magnitude and associations with renal dysfunction

BACKGROUND The hemodynamic alterations seen in liver cirrhosis lead to renal vasoconstriction,ultimately causing acute kidney injury(AKI).The renal resistive index(RRI)is the most common Doppler ultrasound variable for measuring intrarenal vascular resistance.AIM To evaluate the association of the RRI with AKI in patients with liver cirrhosis and to identify risk factors for high RRI.METHODS This was a prospective observational study,where RRI was measured using Doppler ultrasound in 200 consecutive hospitalized patients with cirrhosis.The association of RRI with AKI was studied.The receiver operating characteristic(ROC)curve analysis was utilized to determine discriminatory cut-offs of RRI for various AKI phenotypes.Multivariate analysis was conducted to determine the predictors of high RRI.RESULTS The mean patient age was 49.08±11.68 years,with the majority(79.5%)being male;the predominant etiology of cirrhosis was alcohol(39%).The mean RRI for the study cohort was 0.68±0.09,showing a progressive increase with higher Child-Pugh class of cirrhosis.Overall,AKI was present in 129(64.5%)patients.The mean RRI was significantly higher in patients with AKI compared to those without it(0.72±0.06 vs 0.60±0.08;P<0.001).A total of 82 patients(41%)had hepatorenal syndrome(HRS)-AKI,29(22.4%)had prerenal AKI(PRA),and 18(13.9%)had acute tubular necrosis(ATN)-AKI.The mean RRI was significantly higher in the ATN-AKI(0.80±0.02)and HRS-AKI(0.73±0.03)groups than in the PRA(0.63±0.07)and non-AKI(0.60±0.07)groups.RRI demonstrated excellent discriminatory ability in distinguishing ATN-AKI from non-ATN-AKI(area under ROC curve:93.9%).AKI emerged as an independent predictor of high RRI(adjusted odds ratio[OR]:11.52),and high RRI independently predicted mortality among AKI patients(adjusted OR:3.18).CONCLUSION In cirrhosis patients,RRI exhibited a significant association with AKI,effectively differentiated between AKI phenotypes,and predicted AKI mortality.

Computed tomography-based radiomics to predict early recurrence of hepatocellular carcinoma post-hepatectomy in patients background on cirrhosis

BACKGROUND The prognosis for hepatocellular carcinoma(HCC)in the presence of cirrhosis is unfavourable,primarily attributable to the high incidence of recurrence.AIM To develop a machine learning model for predicting early recurrence(ER)of posthepatectomy HCC in patients with cirrhosis and to stratify patients’overall survival(OS)based on the predicted risk of recurrence.METHODS In this retrospective study,214 HCC patients with cirrhosis who underwent curative hepatectomy were examined.Radiomics feature selection was conducted using the least absolute shrinkage and selection operator and recursive feature elimination methods.Clinical-radiologic features were selected through univariate and multivariate logistic regression analyses.Five machine learning methods were used for model comparison,aiming to identify the optimal model.The model’s performance was evaluated using the receiver operating characteristic curve[area under the curve(AUC)],calibration,and decision curve analysis.Additionally,the Kaplan-Meier(K-M)curve was used to evaluate the stratification effect of the model on patient OS.RESULTS Within this study,the most effective predictive performance for ER of post-hepatectomy HCC in the background of cirrhosis was demonstrated by a model that integrated radiomics features and clinical-radiologic features.In the training cohort,this model attained an AUC of 0.844,while in the validation cohort,it achieved a value of 0.790.The K-M curves illustrated that the combined model not only facilitated risk stratification but also exhibited significant discriminatory ability concerning patients’OS.CONCLUSION The combined model,integrating both radiomics and clinical-radiologic characteristics,exhibited excellent performance in HCC with cirrhosis.The K-M curves assessing OS revealed statistically significant differences.

Advancing hepatic recompensation:Baveno VII criteria and therapeutic innovations in liver cirrhosis management

The Baveno VII criteria redefine the management of decompensated liver cirrhosis,introducing the concept of hepatic recompensation marking a significant departure from the conventional view of irreversible decline.Central to this concept is addressing the underlying cause of cirrhosis through tailored therapies,including antivirals and lifestyle modifications.Studies on alcohol,hepatitis C virus,and hepatitis B virus-related cirrhosis demonstrate the efficacy of these interventions in improving liver function and patient outcomes.Transjugular intrahepatic portosystemic shunt(TIPS)emerges as a promising intervention,effectively resolving complications of portal hypertension and facilitating recompensation.However,optimal timing and patient selection for TIPS remain unresolved.Despite challenges,TIPS offers renewed hope for hepatic recompensation,marking a significant advancement in cirrhosis management.Further research is needed to refine its implementation and maximize its benefits.In conclusion,TIPS stands as a promising avenue for improving hepatic function and patient outcomes in decompensated liver cirrhosis within the framework of the Baveno VII criteria.

Effects of Lactobacillus paracasei N1115 on gut microbial imbalance and liver function in patients with hepatitis B-related cirrhosis

BACKGROUND Hepatitis B cirrhosis(HBC)is a chronic disease characterized by irreversible diffuse liver damage and aggravated by intestinal microbial imbalance and metabolic dysfunction.Although the relationship between certain single probiotics and HBC has been explored,the impact of the complex ready-to-eat Lactobacillus paracasei N1115(LP N1115)supplement on patients with HBC has not been determined.AIM To compare the changes in the microbiota,inflammatory factor levels,and liver function before and after probiotic treatment in HBC patients.METHODS This study included 160 HBC patients diagnosed at the General Hospital of Ningxia Medical University between October 2018 and December 2020.Patients were randomly divided into an intervention group that received LP N1115 supplementation and routine treatment and a control group that received routine treatment only.Fecal samples were collected at the onset and conclusion of the 12-wk intervention period.The structure of the intestinal microbiota and the levels of serological indicators,such as liver function and inflammatory factors,were assessed.RESULTS Following LP N1115 intervention,the intestinal microbial diversity significantly increased in the intervention group(P<0.05),and the structure of the intestinal microbiota was characterized by an increase in the proportions of probiotic microbes and a reduction in harmful bacteria.Additionally,the intervention group demonstrated notable improvements in liver function indices and significantly lower levels of inflammatory factors(P<0.05).CONCLUSION LP N1115 is a promising treatment for ameliorating intestinal microbial imbalance in HBC patients by modulating the structure of the intestinal microbiota,improving liver function,and reducing inflammatory factor levels.

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 ].

Computed tomography-based multi-organ radiomics nomogram model for predicting the risk of esophagogastric variceal bleeding in cirrhosis

BACKGROUND Radiomics has been used in the diagnosis of cirrhosis and prediction of its associated complications.However,most current studies predict the risk of esophageal variceal bleeding(EVB)based on image features at a single level,which results in incomplete data.Few studies have explored the use of global multi-organ radiomics for non-invasive prediction of EVB secondary to cirrhosis.AIM To develop a model based on clinical and multi-organ radiomic features to predict the risk of first-instance secondary EVB in patients with cirrhosis.METHODS In this study,208 patients with cirrhosis were retrospectively evaluated and randomly split into training(n=145)and validation(n=63)cohorts.Three areas were chosen as regions of interest for extraction of multi-organ radiomic features:The whole liver,whole spleen,and lower esophagus–gastric fundus region.In the training cohort,radiomic score(Rad-score)was created by screening radiomic features using the inter-observer and intra-observer correlation coefficients and the least absolute shrinkage and selection operator method.Independent clinical risk factors were selected using multivariate logistic regression analyses.The radiomic features and clinical risk variables were combined to create a new radiomics-clinical model(RC model).The established models were validated using the validation cohort.BACKGROUND Radiomics has been used in the diagnosis of cirrhosis and prediction of its associated complications.However,most current studies predict the risk of esophageal variceal bleeding(EVB)based on image features at a single level,which results in incomplete data.Few studies have explored the use of global multi-organ radiomics for non-invasive prediction of EVB secondary to cirrhosis.AIM To develop a model based on clinical and multi-organ radiomic features to predict the risk of first-instance secondary EVB in patients with cirrhosis.METHODS In this study,208 patients with cirrhosis were retrospectively evaluated and randomly split into training(n=145)and validation(n=63)cohorts.Three areas were chosen as regions of interest for extraction of multi-organ radiomic features:The whole liver,whole spleen,and lower esophagus–gastric fundus region.In the training cohort,radiomic score(Rad-score)was created by screening radiomic features using the inter-observer and intra-observer correlation coefficients and the least absolute shrinkage and selection operator method.Independent clinical risk factors were selected using multivariate logistic regression analyses.The radiomic features and clinical risk variables were combined to create a new radiomics-clinical model(RC model).The established models were validated using the validation cohort.RESULTS The RC model yielded the best predictive performance and accurately predicted the EVB risk of patients with cirrhosis.Ascites,portal vein thrombosis,and plasma prothrombin time were identified as independent clinical risk factors.The area under the receiver operating characteristic curve(AUC)values for the RC model,Rad-score(liver+spleen+esophagus),Rad-score(liver),Rad-score(spleen),Rad-score(esophagus),and clinical model in the training cohort were 0.951,0.930,0.801,0.831,0.864,and 0.727,respectively.The corresponding AUC values in the validation cohort were 0.930,0.886,0.763,0.792,0.857,and 0.692.CONCLUSION In patients with cirrhosis,combined multi-organ radiomics and clinical model can be used to non-invasively predict the probability of the first secondary EVB.

Road to recompensation:BavenoⅦcriteria and transjugular intrahepatic portosystemic shunt in liver cirrhosis

Liver cirrhosis has long been considered a point of no return,with limited hope for recovery.However,recent advancements,particularly the Baveno VII criteria and the utilization of transjugular intrahepatic portosystemic shunt(TIPS),have illuminated the concept of hepatic recompensation.In this editorial we comment on the article by Gao et al published in the recent issue.This editorial provides a comprehensive overview of the evolution of understanding cirrhosis,the criteria for recompensation,and the efficacy of TIPS in achieving recompensation.We discuss key findings from recent studies,including the promising outcomes observed in patients who achieved recompensation post-TIPS insertion.While further research is needed to validate these findings and elucidate the mechanisms underlying recompensation,the insights presented here offer renewed hope for patients with decompensated cirrhosis and highlight the potential of TIPS as a therapeutic option in their management.

Transjugular intrahepatic portosystemic shunt for recompensating decompensated cirrhosis?

Transjugular intrahepatic portosystemic shunt(TIPS)is a medical procedure that has been used to manage variceal bleeding and ascites in patients with cirrhosis.It can prevent further decompensation and improve the survival of high-risk decompensated patients.Recent research indicates that TIPS could increase the possibility of recompensation of decompensated cirrhosis when it is combined with adequate suppression of the causative factor of liver disease.However,the results of the studies have been based on retrospective analysis,and further validation is required by conducting randomized controlled studies.In this context,we highlight the limitations of the current studies and emphasize the issues that must be addressed before TIPS can be recommended as a potential recompensating tool.

sTREM-1 as promising prognostic biomarker for acute-on-chronic liver failure and mortality in patients with acute decompensation of cirrhosis

BACKGROUND Acute decompensation(AD)of cirrhosis is associated with high short-term mortality,mainly due to the development of acute-on-chronic liver failure(ACLF).Thus,there is a need for biomarkers for early and accurate identification of AD patients with high risk of development of ACLF and mortality.Soluble triggering receptor expressed on myeloid cells-1(sTREM-1)is released from activated innate immune cells and correlated with various inflammatory processes.AIM To explore the prognostic value of sTREM-1 in patients with AD of cirrhosis.METHODS A multicenter prospective cohort of 442 patients with cirrhosis hospitalized for AD was divided into a study cohort(n=309)and validation cohort(n=133).Demographic and clinical data were collected,and serum sTREM-1 was measured at admission.All enrolled patients were followed-up for at least 1 year.RESULTS In patients with AD and cirrhosis,serum sTREM-1 was an independent prognosis predictor for 1-year survival and correlated with liver,coagulation,cerebral and kidney failure.A new prognostic model of AD(P-AD)incorporating sTREM-1,blood urea nitrogen(BUN),total bilirubin(TBil),international normalized ratio(INR)and hepatic encephalopathy grades was established and performed better than the model for end-stage liver disease(MELD),MELD-sodium(MELD-Na),chronic liver failure-consortium(CLIF-C)ACLF and CLIF-C AD scores.Additionally,sTREM-1 was increased in ACLF and predicted the development of ACLF during first 28-d follow-up.The ACLF risk score incorporating serum sTREM-1,BUN,INR,TBil and aspartate aminotransferase levels was established and significantly superior to MELD,MELD-Na,CLIF-C ACLF,CLIF-C AD and P-AD in predicting risk of ACLF development.CONCLUSION Serum sTREM-1 is a promising prognostic biomarker for ACLF development and mortality in patients with AD of cirrhosis.

Red cell distribution width/platelet ratio estimates the 3-year risk of decompensation in Metabolic Dysfunction-Associated Steatotic Liver Disease-induced cirrhosis

BACKGROUND For compensated advanced chronic liver disease(cACLD)patients,the first decompensation represents a dramatically worsening prognostic event.Based on the first decompensation event(DE),the transition to decompensated advanced chronic liver disease(dACLD)can occur through two modalities referred to as acute decompensation(AD)and non-AD(NAD),respectively.Clinically Significant Portal Hypertension(CSPH)is considered the strongest predictor of decompensation in these patients.However,due to its invasiveness and costs,CSPH is almost never evaluated in clinical practice.Therefore,recognizing noninvasively predicting tools still have more appeal across healthcare systems.The red cell distribution width to platelet ratio(RPR)has been reported to be an indicator of hepatic fibrosis in Metabolic Dysfunction-Associated Steatotic Liver Disease(MASLD).However,its predictive role for the decompensation has never been explored.AIM In this observational study,we investigated the clinical usage of RPR in predicting DEs in MASLD-related cACLD patients.METHODS Fourty controls and 150 MASLD-cACLD patients were consecutively enrolled and followed up(FUP)semiannually for 3 years.At baseline,biochemical,clinical,and Liver Stiffness Measurement(LSM),Child-Pugh(CP),Model for End-Stage Liver Disease(MELD),aspartate aminotransferase/platelet count ratio index(APRI),Fibrosis-4(FIB-4),Albumin-Bilirubin(ALBI),ALBI-FIB-4,and RPR were collected.During FUP,DEs(timing and modaities)were recorded.CSPH was assessed at the baseline and on DE occurrence according to the available Clinical Practice Guidelines.RESULTS Of 150 MASLD-related cACLD patients,43(28.6%)progressed to dACLD at a median time of 28.9 months(29 NAD and 14 AD).Baseline RPR values were significantly higher in cACLD in comparison to controls,as well as MELD,CP,APRI,FIB-4,ALBI,ALBI-FIB-4,and LSM in dACLD-progressing compared to cACLD individuals[all P<0.0001,except for FIB-4(P:0.007)and ALBI(P:0.011)].Receiving operator curve analysis revealed RPR>0.472 and>0.894 as the best cut-offs in the prediction respectively of 3-year first DE,as well as its superiority compared to the other non-invasive tools examined.RPR(P:0.02)and the presence of baseline-CSPH(P:0.04)were significantly and independently associated with the DE.Patients presenting baseline-CSPH and RPR>0.472 showed higher risk of decompensation(P:0.0023).CONCLUSION Altogether these findings suggest the RPR as a valid and potentially applicable non-invasive tool in the prediction of timing and modalities of decompensation in MASLD-related cACLD patients.

Risk factors for hepatocellular carcinoma in cirrhosis:A comprehensive analysis from a decade-long study

BACKGROUND Cirrhosis is a significant risk factor for the development of hepatocellular carcinoma(HCC).Variability in HCC risk among patients with cirrhosis is notable,particularly when considering the diverse etiologies of cirrhosis.AIM To identify specific risk factors contributing to HCC development in patients with cirrhosis.METHODS This retrospective study analyzed data from cirrhotic patients at Beijing Youan Hospital from January 1,2012 to September 30,2022 with at least 6 mo of followup.Patient demographics,medical histories,etiologies,and clinical characteristics were examined.Cox regression analysis was used to analyze correlations of the above parameters with hepatocarcinogenesis,while competing risk regression was used to estimate their adjusted hazard ratios accounting for death.The cumulative incidence was plotted over time.RESULTS Overall,5417 patients with cirrhosis(median age:54 years;65.8%males)were analyzed.Hepatitis B virus(HBV)was the most common etiology(23.3%),with 25%(n=1352)developing HCC over a 2.9-year follow-up period.Patients with multiple etiologies had the HCC highest incidence(30.3%),followed by those with HBV-related cirrhosis(29.5%).Significant risk factors included male sex,advanced age,hepatitis C virus(HCV)infection,elevated blood ammonia,and low platelet count.Men had a higher 5-year HCC risk than women(37.0%vs 31.5%).HBV,HCV,and HBV/HCV co-infected patients had 5-year risks of HCC of 45.8%,42.9%,and 48.1%,respectively,compared to 29.5%in nonviral hepatitis cases,highlighting the significant HCC risk from viral hepatitis,especially HBV,and underscores the importance of monitoring these high-risk groups.CONCLUSION In conclusion,HBV-related cirrhosis strongly correlates with HCC,with male sex,older age,viral hepatitis,elevated blood ammonia,and lower albumin and platelet levels increasing the risk of HCC.

Predictive model for non-malignant portal vein thrombosis associated with cirrhosis based on inflammatory biomarkers

BACKGROUND Portal vein thrombosis(PVT),a complication of liver cirrhosis,is a major public health concern.PVT prediction is the most effective method for PVT diagnosis and treatment.AIM To develop and validate a nomogram and network calculator based on clinical indicators to predict PVT in patients with cirrhosis.METHODS Patients with cirrhosis hospitalized between January 2016 and December 2021 at the First Hospital of Lanzhou University were screened and 643 patients with cirrhosis who met the eligibility criteria were retrieved.Following a 1:1 propensity score matching 572 patients with cirrhosis were screened,and relevant clinical data were collected.PVT risk factors were identified using the least absolute shrinkage and selection operator(LASSO)and multivariate logistic regression analysis.Variance inflation factors and correlation matrix plots were used to analyze multicollinearity among the variables.A nomogram was constructed to predict the probability of PVT based on independent risk factors for PVT,and its predictive performance was verified using a receiver operating characteristic curve(ROC),calibration curves,and decision curve analysis(DCA).Finally,a network calculator was constructed based on the nomograms.RESULTS This study enrolled 286 cirrhosis patients with PVT and 286 without PVT.LASSO analysis revealed 13 variables as strongly associated with PVT occurrence.Multivariate logistic regression analysis revealed nine indicators as independent PVT risk factors,including etiology,ascites,gastroesophageal varices,platelet count,D-dimer,portal vein diameter,portal vein velocity,aspartate transaminase to neutrophil ratio index,and platelet-to-lymphocyte ratio.LASSO and correlation matrix plot results revealed no significant multicollinearity or correlation among the variables.A nomogram was constructed based on the screened independent risk factors.The nomogram had excellent predictive performance,with an area under the ROC curve of 0.821 and 0.829 in the training and testing groups,respectively.Calibration curves and DCA revealed its good clinical performance.Finally,the optimal cutoff value for the total nomogram score was 0.513.The sensitivity and specificity of the optimal cutoff values were 0.822 and 0.706,respectively.CONCLUSION A nomogram for predicting PVT occurrence was successfully developed and validated,and a network calculator was constructed.This can enable clinicians to rapidly and easily identify high PVT risk groups.

Clinical review and literature analysis of hepatic epithelioid angiomyolipoma in alcoholic cirrhosis: A case report

BACKGROUND Hepatic epithelioid angiomyolipoma(HEA)has a low incidence and both clinical manifestations and imaging lack specificity.Thus,it is easy to misdiagnose HEA as other tumors of the liver,especially in the presence of liver diseases such as hepatitis cirrhosis.This article reviewed the diagnosis and treatment of a patient with HEA and alcoholic cirrhosis,and analyzed the literature,in order to improve the understanding of this disease.CASE SUMMARY A 67-year-old male patient with a history of alcoholic cirrhosis was admitted due to the discovery of a space-occupying lesion in the liver.Based on the patient’s history,laboratory examinations,and imaging examinations,a malignant liver tumor was considered and laparoscopic partial hepatectomy was performed.Postoperative pathology showed HEA.During outpatient follow-up,the patient showed no sign of recurrence.CONCLUSION HEA is difficult to make a definite diagnosis before surgery.HEA has the poten-tial for malignant degeneration.If conditions permit,surgical treatment is recom-mended.

Hematological abnormalities in liver cirrhosis

Hematological abnormalities are common in cirrhosis and are associated with various pathophysiological mechanisms.Studies have documented a prevalence of thrombocytopenia,leukopenia,and anemia in patients with compensated cirrhosis of 77.9%,23.5%,and 21.1%,respectively.These abnormalities carry significant clinical implications,including considerations for invasive procedures,infection risk,bleeding risk,and prognosis.Previously,cirrhosis was believed to predispose patients to bleeding due to alterations observed in classical coagula-tion tests such as prothrombin time,partial thromboplastin time,international normalized ratio,and thrombocytopenia.However,this understanding has evol-ved,and cirrhosis patients are now also acknowledged as being at a high risk for thrombotic events.Hemostasis in cirrhosis patients presents a complex pheno-type,with procoagulant and anticoagulant abnormalities offsetting each other.This multifactorial phenomenon is inadequately reflected by routine laboratory tests.Thrombotic complications are more prevalent in decompensated cirrhosis and may correlate with disease severity.Bleeding is primarily associated with portal hypertension,endothelial dysfunction,mechanical vessel injury,dissem-inated intravascular coagulation,endotoxemia,and renal injury.This review comprehensively outlines hematologic index abnormalities,mechanisms of hemostasis,coagulation,and fibrinolysis abnormalities,limitations of laboratory testing,and clinical manifestations of bleeding and thrombosis in patients with liver cirrhosis.

Development and validation of biomarkers related to anoikis in liver cirrhosis based on bioinformatics analysis

BACKGROUND According to study,anoikis-related genes(ARGs)have been demonstrated to play a significant impact in cirrhosis,a major disease threatening human health worldwide.AIM To investigate the relationship between ARGs and cirrhosis development to provide insights into the clinical treatment of cirrhosis.METHODS RNA-sequencing data related to cirrhosis were obtained from the Gene Expression Omnibus database.Differentially expressed genes(DEGs)between cirrhotic and normal tissues were intersected with ARGs to derive differentially expressed ARGs(DEARGs).The DEARGs were filtered using the least absolute shrinkage and selection operator,support vector machine recursive feature elimination,and random forest algorithms to identify biomarkers for cirrhosis.These biomarkers were used to create a nomogram for predicting the prognosis of cirrhosis.The proportions of diverse immune cell subsets in cirrhotic vs normal tissues were compared using the CIBERSORT computational method.In addition,the linkage between immune cells and biomarkers was assessed,and a regulatory network of mRNA,miRNA,and transcription factors was constructed relying on the biomarkers.RESULTS The comparison of cirrhotic and normal tissue samples led to the identification of 635 DEGs.Subsequent intersection of the DEGs with ARGs produced a set of 26 DEARGs.Subsequently,three DEARGs,namely,ACTG1,STAT1,and CCR7,were identified as biomarkers using three machine-learning algorithms.The proportions of M1 and M2 macrophages,resting CD4 memory T cells,resting mast cells,and plasma cells significantly differed between cirrhotic and normal tissue samples.The proportions of M1 and M2 macrophages,resting CD4 memory T cells,and resting mast cells were significantly correlated with the expression of the three biomarkers.The mRNA–miRNA–TF network showed that ACTG1,CCR7,and STAT1 were regulated by 28,42,and 35 miRNAs,respectively.Moreover,AR,MAX,EP300,and FOXA1 were found to regulate four miRNAs related to the biomarkers.CONCLUSION This study revealed ACTG1,STAT1,and CCR7 as biomarkers of cirrhosis,providing a reference for developing novel diagnostic and therapeutic strategies for cirrhosis.
