Predictive Value of Serum Lactate Levels for Mortality in Patients with Hepatitis B-Related Decompensated Cirrhosis: A Retrospective Analysis

Aims/Background Decompensated cirrhosis is characterized by the progression of cirrhosis from an asymptomatic state to elevated portal pressure and marked deterioration of liver function. This pathological condition progresses rapidly following onset, significantly raising the risk for mortality. The aim of this study is to explore the association between serum lactate concentrations and mortality rates in individuals with hepatitis B-induced decompensated cirrhosis and to evaluate its potential as a clinical prognostic indicator. Methods This retrospective analysis involved 200 individuals (134 men and 66 women) diagnosed with decompensated cirrhosis related to hepatitis B and hospitalized between March 2017 and May 2023. Out of these patients, 162 survived while 38 did not. Clinical information and laboratory results, including the Model for End-Stage Liver Disease (MELD) score, Child-Pugh score, and serum lactate levels, were collected. Logistic regression was applied to identify mortality risk factors from the patient sample and groups categorized according to gender. The predictive value of serum lactate levels for mortality was assessed using the area under the curve (AUC), i.e., receiver operating characteristic (ROC) curve. Results The surviving patient group showed significantly lowered MELD scores, Child-Pugh scores, and serum lactate levels compared to those who were deceased (p < 0.05). Multivariate analysis revealed that the MELD score, Child-Pugh score, and serum lactate levels were independent predictors of mortality in patients with decompensated hepatitis B cirrhosis, with odds ratios (OR) of 1.321, 1.432, and 49.082, respectively (p = 0.012, 0.028, and <0.001, respectively). Additionally, the OR for serum lactate levels was notably higher in female patients compared to male patients (46.824 vs. 30.451). Thus, the MELD score, Child-Pugh score, and serum lactate levels are effective predictors for mortality in cirrhosis patients (AUCs = 0.628, 0.675, and 0.809; p = 0.014, 0.001, and <0.001, respectively), with serum lactate levels showing the most excellent predictive efficacy profile (sensitivity 65.8% and specificity 97.5%). Additionally, the AUC value for serum lactate levels was lower in male patients (0.785) compared to female patients (0.875), indicating that changes in serum lactate levels were more sensitive in female patients. In summary, serum lactate concentration is a prognostic indicator of mortality in individuals with decompensated cirrhosis due to hepatitis B, exhibiting higher predictive significance in female patients. Conclusion Deceased patients with decompensated cirrhosis linked to hepatitis B exhibit markedly increased serum lactate levels. Thus, monitoring serum lactate levels offers an effective tool for predicting patient prognosis, exhibiting higher sensitivity for disease detection in female patients.

Case report: CAR-T therapy demonstrated safety and efficacy in relapsed/refractory diffuse large B-cell lymphoma patients complicated with hepatitis B-related cirrhosis

Chimeric antigen receptor T-cell (CAR-T) therapy has demonstrated both efficacy and safety in relapsed/refractory diffuse large B-cell lymphoma (DLBCL) patients infected with hepatitis B virus (HBV). However, its applicability in individuals with liver cirrhosis remains largely unexplored due to the potential for unpredictable complications. Here, we report three cases (P1, P2, and P3) of relapsed/refractory DLBCL with HBV-related cirrhosis treated with CAR-T cell infusion. P1 and P2 received CAR-T cell infusion following a conditioning regimen of fludarabine and cyclophosphamide (FC) for lymphodepletion, while P3 received the SEAM (semustine, etoposide, cytarabine, and melphalan) regimen and autologous stem cell transplantation bridging CAR-T cell infusion. P1 and P2 achieved rapid complete remission (CR), whereas P3 initially exhibited stable disease a month after CAR-T infusion and subsequently achieved CR after local radiation salvage therapy and lenalidomide maintenance. With a median follow-up of 42 months after CAR-T, the progression-free survival rate was 100%. Notably, during follow-up, these patients experienced complications associated with cirrhosis, including endoscopic variceal bleeding, HBV reactivation, or the diagnosis of hepatic malignancy. Our findings suggest that CAR-T therapy is applicable and effective for the treatment of DLBCL patients with HBV-related cirrhosis, albeit necessitating monitoring for potential hepatic complications.

Risk assessment of hepatocellular carcinoma in patients with hepatitis B-related cirrhosis and hypertension: a propensity score matching-based retrospective cohort study

To analyze the factors affecting the risk of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B-associated cirrhosis (CHB-Cir) complicated by essential hypertension (EH) and explore the impact of EH on HCC risk in patients with CHB-Cir. This study was conducted among the patients with CHB-Cir with or without EH received antiviral therapy in the Infectious Disease Department, Third Affiliated Hospital of Xinxiang Medical University from January, 2017 to January, 2024. The cases with insufficient follow-up time or missing data were excluded. The patients were subjected to propensity score matching in a 1:1 ratio to form an EH group and a non-EH group. The Kaplan-Meier method was used to compare the cumulative incidence of HCC between the two groups, and the Cox proportional hazards regression model was used to analyze the risk of HCC and the factors affecting HCC risk. A total of 390 CHB-Cir patients (274 male and 116 female patients) were enrolled in this study, including 195 with EH and 195 without EH. In these patients, EH was significantly correlated with the occurrence of HCC (HR=1.69, P=0.002). Multivariate analysis suggested that the male gender (HR=1.73, P=0.005), a family history of liver cancer (HR=2.23, P < 0.001), elevated alpha-fetoprotein (HR=2.83, P=0.001), elevated glutathione reductase (HR=1.53, P=0.046), reduced high-density lipoprotein (HR=1.46, P=0.027), and elevated low-density lipoprotein (HR=2.29, P=0.003) were all significantly correlated with HCC occurrence, while elevated triglycerides (HR= 0.37, P < 0.001) was a protective factor against HCC. In the EH group, treatment with non-RASIs drugs (HR=2.77, P=0.021) and no treatment/diuretic treatment (HR=7.18, P < 0.001) were significantly correlated with HCC occurrence. Hypertension increases the risk of HCC in patients with CHB-Cir, suggesting the importance of controlling hypertension in these patients.

A comprehensive evaluation system for ultrasound-guided infusion of human umbilical cord-derived MSCs in liver cirrhosis patients.

Infusion of mesenchymal stem cells (MSCs) via portal vein is one of the main ways for MSCs transplantation to treat liver cirrhosis (LC). As the tissue of LC showed diffuse fibrosis and thickened Glission sheath, the soft pig-tail catheter, or central venous catheter can not successfully insert the portal vein. Thus, our study used an improved method and performed a relatively comprehensive system to evaluate the effect for human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) transplantation. Fifteen patients with hepatitis B-related cirrhosis were enrolled in the study, and we performed hUC-MSCs transplantation via portal vein by using an 16-G needle and 0.035-inch guide wire combined with 7FR "retentional metal stiffner trocar" of pig-tail catheter under the guidance of contrast-enhanced ultrasound. Serum liver function, fibrotic indicators, tissue stiffness, coagulation function, and hemodynamics were measured at weeks 4, 12, and 24 after MSCs transplantation. Liver biopsy was performed before and 24 weeks after hUC-MSCs transplantation. After hUC-MSCs transplantation, the prothrombin time was lower than before. The levels of hyaluronic acid and IV-C(Type IV collagen) in fibrotic indicators were significantly reduced, and the Young's modulus was also decreased. Moreover, liver biopsy showed that the lytic necrosis of hepatocyte was decreased. In liver hemodynamics, the portal vein diameter was decreased after hUC-MSCs transplantation. hUC-MSCs transplantation can alleviate liver damage caused by LC. The improved "retentional metal stiffner trocar" of pig-tail catheter was safe and effective in the infusion of hUC-MSCs transplantation, which is worth promoting in clinical practice.

Screening of Cancer-Specific Biomarkers for Hepatitis B-Related Hepatocellular Carcinoma Based on a Proteome Microarray

Hepatocellular carcinoma (HCC) is associated with one of the highest mortality rates among cancers, rendering its early diagnosis clinically invaluable. Serum biomarkers, specifically alpha-fetoprotein (AFP), represent the most promising and widely used diagnostic biomarkers for HCC. However, its detection rate is low in the early stages of HCC progression, and distinguishing specific false positives for other liver-related diseases, such as cirrhosis and acute hepatitis, remains challenging. Therefore, this study was conducted to identify biomarkers for hepatitis B (HBV)-related liver diseases by screening differentially expressed autoantibodies against tumor-associated antigens (TAAbs). We designed a large-scale multistage investigation, encompassing initial screening, HCC-focused, and ELISA validation cohorts to identify potential TAAbs in HBV-related liver diseases, spanning from healthy control (HC) individuals to patients with chronic hepatitis B (CHB), hepatitis B-related cirrhosis (HBC), and HCC, using protein microarray technology. The differential biological characteristics of TAAbs were analyzed using bioinformatics analysis. Validation of tumor-specific biomarkers for HCC was performed using ELISA. In the screening cohort, 547 candidate TAAbs were identified in the HCC group compared to those in the HC group. In the HCC-focused cohort, 64, 61, and 65 candidate TAAbs were identified in the CHB, HBC, and HCC groups, respectively, compared to those in the HC group. Thirty-four proteins exhibited continuously elevated expression from HCs to patients with CHB, HBC, and HCC. Among these, nine were identified as cancer-specific proteins. In the validation cohort, UBE2Z, CNOT3, and EID3 were correlated with liver function indicators in patients with hepatitis B-related HCC. Overall, UBE2Z, CNOT3, and EID3 emerged as cancer-specific biomarkers for HBV-related liver disease, providing a scientific basis for clinical application.

A case study of consecutive pregnancies in a woman with liver cirrhosis and portal hypertension

Pregnancy in women with liver cirrhosis is a high-risk one that requires multidisciplinary care. Variceal bleeding occurs in up to half of women having associated portal hypertension and confers the greatest risk. Despite advances made in the management of such cases, maternal morbidity remains high. Pregnancy is rare in women with liver cirrhosis due to reduced natural fertility rates. We report a case of two consecutive pregnancies in a woman with liver cirrhosis. A 29-year-old primipara with hepatitis B-related liver cirrhosis with portal hypertension who had been on tenofovir for the past seven years. The first pregnancy was spontaneously conceived but the second was by assisted conception. Both pregnancies were complicated by recurrent episodes of variceal bleeding that necessitated multiple endoscopic variceal band ligation (EVBL) during pregnancy. Medical advancement has enabled women with cirrhosis to have more pregnancies with reduced maternal and perinatal morbidities. Multidisciplinary management is vital to achieving favourable pregnancy outcomes.

Fibrinogen dysfunction and fibrinolysis state in patients with hepatitis B-related cirrhosis

ABSTRACT Objective To assess the fibrinogen function in patients with hepatitis B-related cirrhosis and explore the relationship between dysfibrinogenemia and bleeding and thrombotic events. Methods Medical records and laboratory data of the patients with hepatitis B-related cirrhosis were collected. Patients were categorized into three groups based on the Child-Pugh score. Fibrinogen activity and antigen, fibrinogen-bound sialic acid (FSA), fibrinogen polymerization and fibrinolysis kinetic analysis, thrombin-antithrombin complex (TAT) and plasmin-α2-antiplasmin complex (PAP) were detected. Results Eighty patients with seventeen, thirty-eight and twenty-five in Child-Pugh A, B and C, respectively, were included. Seventeen patients experienced bleeding events and eight patients had thrombotic events. Fibrinogen activity and antigen levels were reduced with the severity of cirrhosis. Twenty-two patients exhibited dysfibrinogenemia. The FSA levels in patients with non-dysfibrinogenemia and those with dysfibrinogenemia were increased to 1.25 and 1.37 times of healthy controls, negatively correlated with fibrinogen activity (ρ = −0.393, p = 0.006). Compared to healthy controls, the amount of clot formation was reduced (p < 0.001), the polymerization was delayed (p < 0.001) and the rate of fibrinolysis was reduced (p < 0.001). The TAT levels were significantly increased in the Child-Pugh C patients compared to the Child-Pugh B patients (p = 0.032) while the PAP levels were comparable among 3 groups (p = 0.361). Conclusion Sialylation of fibrinogen is one of the main causes of modifications of fibrinogen in patients with hepatitis B-related cirrhosis. The polymerization and fibrinolysis functions of fibrinogen are impaired. The degree of impaired fibrinolysis function is more severe than that of polymerization function, and may be partly related to the occurrence of thrombotic events.

Associations between single nucleotide polymorphisms of cytokines and hepatitis B virus-related liver cirrhosis: A case-controlstudy.

Various inflammatory and immune cytokines play key roles in the progression of hepatitis B virus (HBV)-related liver cirrhosis (LC). This study explored the relationship between single nucleotide polymorphisms (SNPs) in cytokines with the combined effect of polymorphisms and gender-polymorphisms interaction and LC risk. In this study, a case-control design was used, samples were selected from 45 patients with hepatitis B-related cirrhosis and 45 age-gender-matched chronic HBV-infected patients without cirrhosis attending the tumor hospital of Wuwei Academy of Medical Sciences. Fifteen SNPs were examined using a real-time polymerase chain reaction allelic discrimination system. Logistic regression was utilized to assess cytokine-associated SNPs and the association between SNPs and LC progression in HBV-infected patients. The multivariate-adjusted logistic model revealed that the GG/AG dominant model (OR, 16.38; 95% CI, 1.13-236.70) and G allele (OR, 5.93; 95% CI, 0.98-36.01) of rs1800896 were associated with an increased risk of cirrhosis in CHB patients. Instead, rs2227306 CT presented a reduced cirrhosis risk (OR, 0.22; 95% CI, 0.04-1.38). Rs2055979 AA/AC was negatively associated with the risk of cirrhosis, potentially reversed in males (p = 0.021). Rs1799964 CC/CT was positively related to the risk of cirrhosis but reduced the risk of cirrhosis in males (OR, 0.13; 95% CI, 0.022-0.808; p = 0.028). Both rs1799964 TT and rs1799724 CT/TT genotype showed a synergistic effect in reducing the risk of cirrhosis with rs1800896 AA (OR, 0.08; 95% CI, 0.01-1.43 and OR, 0.12; 95% CI, 0.01-2.21). Polymorphisms rs1800896 and rs2227306 are potentially associated with the risk of cirrhosis. For the first time, the study highlights that the rs2055979 AA/AC and rs1799964 CC/CT polymorphism interact with gender and its potential reversal of cirrhosis risk in males. Furthermore, rs1800896 AA showed a synergistic effect with rs1799964 TT and rs1799724 CT/TT to prevent the progression of HBV infection to cirrhosis.

Relationship Between Serum HBV-RNA Levels, Sero-biochemical Indices, and Clinicopathological Parameters in Patients with Hepatitis B Virus

Background: Studies have indicated that HBV RNA exhibits a distinct profile, and the plasma amino acid profile significantly correlates with the different stages of HBV infection. Objectives: This study investigates the relationship between HBV RNA and the plasma amino acid profile and the levels of HBeAg, HBsAg, HBV DNA levels, and other clinical indexes in diagnosing chronic HBV infection diseases. Methods: In this observational study, a total of 155 patients were included. They were categorized as Hepatitis B virus carriers, chronic Hepatitis B (CHB), Hepatitis B-related cirrhosis, and hepatocellular carcinoma patients. Following routine laboratory techniques, the DNA, RNA, serological indexes (HBsAg, HBsAb, HBeAg, HBeAb, and HBcAb), biochemical indexes (ALT, AST), and the concentration of amino acids were determined from the serum. Results: Any relationship between different parameters considered was determined with the chi-square test, correlation, and multivariate logistic regression analysis. We observed that the HBV DNA and RNA levels were significantly higher in patients with chronic Hepatitis B compared to other groups (P &lt; 0.01). The HBV RNA levels significantly correlated with methionine levels (P &lt; 0.05) and not with other amino acids considered in this study. Further, the HBV DNA levels emerged as an independent risk factor for HBV RNA levels, and the area under the ROC curve was 0.840 (P &lt; 0.01) when the levels of HBV RNA, HBV DNA, and methionine were combined to diagnose chronic Hepatitis B. Conclusions: Our study shows that the levels of HBV RNA are correlated with methionine metabolism levels, and this relationship can be used to diagnose and predict the efficacy of treatment for different stages of HepatitisHepatitis B virus infectious diseases.

Comparison of Autolumo A2000 Plus and Architect i2000 for detection of hepatitis B virus serological markers

Serological detection of hepatitis B virus markers plays a vital role in the diagnosis, treatment, prognosis, and therapeutic surveillance of hepatitis B. To compare the diagnostic performance of Autolumo A2000Plus and Abbott Architect i2000 systems in the detection of hepatitis B infection markers. A total of 6 HBV seroconversion panels and 743 participants were enrolled in this study, including 383 HBV-infected patients and 360 healthy adults. Clinical diagnostic information, laboratory results, and HBV genotyping were collected to evaluate the diagnostic performance of the A2000Plus and i2000 systems in detecting HBV infection markers. The results showed that the total percent agreement of HBV markers was all >90 % in both detection systems among the six seroconversion panels and 743 serum samples from the population. The χ2 values of the Chi-square test among hepatitis B virus serological markers in both analyzers were between 550.7 and 743.0, p < 0.0001. HBV marker consistency test results show perfect consistency between the two analyzers, with Kappa values ranging from 0.854 to 1.000. For specific samples, including Hepatitis B patients with Genotype C, chronic hepatitis B, hepatitis B-related cirrhosis, and hepatocellular carcinoma, spearman correlation analysis showed HBsAg correlation coefficients ranging from 0.8532 to 0.9745, p < 0.001 in both analyzers. In conclusion, Autolumo A2000Plus diagnostic performance in consistency and correlation is comparable to Abbott Architect i2000 when detecting markers of hepatitis B infection. The Autolumo A2000Plus system can be used as a reliable instrument for HBV marker detection.

Obliteration of portal venules contributes to portal hypertension in biliary cirrhosis.

The effects of the obliteration of portal venules (OPV) in cirrhotic portal hypertension are poorly understood. To investigate its contribution to portal hypertension in biliary cirrhosis and its underlying mechanism,we evaluated OPV using two-dimensional (2D) histopathology in liver explants from patients with biliary atresia (BA, n = 63), primary biliary cholangitis (PBC, n = 18), and hepatitis B-related cirrhosis (Hep-B-cirrhosis, n = 35). Then, three-dimensional (3D) OPV was measured by X-ray phase-contrast CT in two parallel models in rats following bile duct ligation (BDL) or carbon tetrachloride (CCl4) administration, representing biliary cirrhosis and post-necrotic cirrhosis, respectively. The portal pressure was also measured in the two models. Finally, the effects of proliferative bile ducts on OPV were investigated. We found that OPV was significantly more frequent in patients with biliary cirrhosis, including BA (78.57 ± 16.45%) and PBC (60.00 ± 17.15%), than that in Hep-B-cirrhotic patients (29.43 ± 14.94%, p < 0.001). OPV occurred earlier, evidenced by the paired liver biopsy at a Kasai procedure (KP), and was irreversible even after a successful KP in the patients with BA. OPV was also significantly more frequent in the BDL models than in the CCl4 models, as shown by 2D and 3D quantitative analysis. Portal pressure was significantly higher in the BDL model than that in the CCl4 model. With the proliferation of bile ducts, portal venules were compressed and irreversibly occluded, contributing to the earlier and higher portal pressure in biliary cirrhosis. OPV, as a pre-sinusoidal component, plays a key role in the pathogenesis of portal hypertension in biliary cirrhosis. The proliferated bile ducts and ductules gradually take up the 'territory' originally attributed to portal venules and compress the portal venules, which may lead to OPV in biliary cirrhosis. © 2024 The Pathological Society of Great Britain and Ireland.

Evaluate the clinical efficacy of traditional Chinese Medicine as the neoadjuvant treatment in reducing the incidence of hepatocellular carcinoma in patients with hepatitis B-related cirrhosis: A systematic review and meta-analysis

BackgroundTraditional Chinese Medicine (TCM), has been used for hepatocellular carcinoma (HCC) at every therapeutic stage, even before tumor formation. However, the efficacy of TCM in reducing the incidence of HCC in patients with chronic hepatitis B-related cirrhosis remains unclear. This study aims to address this gap. MethodsPublications were collected from PubMed, EMBASE, Cochrane Library, Web of Science, CNKI, Sino Med, VIP, and Wan Fang Databases. Relative risk (RR) was calculated with a 95 % confidence interval (CI). Heterogeneity was assessed. The Cochrane Collaboration's tool was used to assess the risk of bias. Results10 studies with 2702 patients showed that the combination therapy significantly reduced the incidence of HCC in patients with post-hepatitis B cirrhosis at 1, 3, and 5 years. However, the preventive effects of TCM were in compensated cirrhosis, but not the decompensated cirrhosis. Furthermore, TCM correlated with improved liver function and enhanced virological response. ConclusionCombination therapy with TCM demonstrated the certain potential in reducing the incidence of HCC in patients with hepatitis B cirrhosis. This is attrinuted to the improvement of liver function and enhancement of the viral response. However, the efficacy of TCM in the field still needs more high-quality RCTs to provide stronger evidence in the future.

Lobe-Based Hepatic Uptake Index of Gd-EOB-DTPA on Contrast-Enhanced MRI to Quantitatively Discriminate between Compensated and Decompensated Hepatitis B-Related Cirrhosis.

To use hepatic uptake index (HUI) of liver lobes on gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI) to discriminate between patients with hepatitis B-related cirrhosis in compensated and decompensated statuses. Forty-four consecutive patients with hepatitis B-related cirrhosis who underwent Gd-EOB-DTPA-enhanced MRI were divided into compensated and decompensated statuses based on clinical evaluation. Volume and signal intensity of individual lobes were retrospectively measured to calculate HUI of the right liver lobe (RHUI), medial (MHUI) and lateral (LHUI) left liver lobes, and caudate lobe (CHUI). Spearman's rank correlation analyses were performed to evaluate relationships of lobe-based HUI with Child-Pugh and model for end-stage liver disease (MELD) scoring system scores in compensated and decompensated statuses. The Mann-Whitney U-test was used to compare the lobe-based HUI between compensated and decompensated statuses. The performance of lobe-based HUI in distinguishing cirrhosis was evaluated using receiver operating characteristic (ROC) analysis, and the area under the ROC curve (AUC) was calculated as a measure of accuracy. Delong's method was used for statistical analysis to elucidate which HUI is optimal. Compensated and decompensated liver cirrhosis were confirmed in 25 (56.82%) and 19 (43.18%) patients, respectively. According to Spearman's rank correlation analysis, RHUI, MHUI, LHUI, and CHUI were all significantly associated with Child-Pugh and MELD scores (all P values <0.05). Receiver operating characteristic analysis demonstrated that among all lobe-based HUI parameters, RHUI could best perform the previous discrimination with a cut-off of 485.73 and obtain an AUC of 0.867. The AUC of RHUI improved and was significantly different from that of MHUI, LHUI, and CHUI (P = 0.03, P = 0.007, and P < 0.001, respectively, Delong's test). The RHUI could help quantitatively discriminate hepatitis B-related cirrhosis between compensated and decompensated statuses.

Predictive value of blood coagulation and routine blood indices for rebleeding after endoscopic treatment in hepatitis B-related cirrhotic patients with esophagogastric fundal varices: a logistic regression model analysis.

To evaluate the predictive value of blood coagulation and routine blood indices for rebleeding after endoscopic treatment of ruptured esophagogastric fundal varices (EGVB) in cirrhotic patients with hepatitis B infection. This retrospective analysis included 248 patients with hepatitis B-related cirrhosis and EGVB who received initial endoscopic treatment from October 2019 to March 2022 and were followed up for 12 months. Patients were divided into rebleeding and non-rebleeding groups. Laboratory indices were analyzed, and univariate and multivariate analyses identified predictors of rebleeding. The efficacy of a logistic regression model was evaluated using Receiver Operating Characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA), and a risk factor nomogram was constructed for assessing the predictive efficiency of those risk factors. Univariate analysis showed significant differences in portal vein diameters and lower Child-Pugh scores in the rebleeding group in contrast to those in the non-rebleeding group. Key laboratory markers such as platelet count (PLT), albumin (ALB), alanine aminotransferase (ALT), lymphocytes (LYM), and prognostic nutritional index (PNI) were lower, while prothrombin time (PT) and lactate levels (LN) were higher in the rebleeding group than those in the non-rebleeding group. Multivariate analysis identified portal vein diameter, PLT, ALT, PT, LYM, and PNI as significant predictors of rebleeding. The logistic model demonstrated high accuracy (AUC=0.986) and clinical value, validated by ROC curves, calibration curves (C-index =0.986), and DCA results. A risk factor predictive nomogram was successfully constructed. This study developed a logistic regression model with a nomogram for predicting EGVB-related rebleeding in patients with hepatitis B-related cirrhosis, achieving an AUC of 0.986, indicating high accuracy and significant clinical relevance.

An improved model based on quantitative features of right liver lobe, maximum varices, and portal vein system measured on magnetic resonance imaging to predict oesophagogastric variceal haemorrhage secondary to hepatitis B-related cirrhosis.

In patients with hepatitis B-related cirrhosis, it is important to predict those at high-risk of oesophagogastric variceal haemorrhage (OVH) to decide upon prophylactic treatment. Our published model developed with right liver lobe volume and diameters of portal vein system did not incorporate maximum variceal size as a factor. This study thus aimed to develop an improved model based on right liver lobe volume, diameters of maximum oesophagogastric varices (OV) and portal vein system obtained at magnetic resonance imaging (MRI) to predict OVH. Two hundred and thirty consecutive individuals with hepatitis B-related cirrhosis undergoing abdominal enhanced MRI were randomly grouped into training (n=160) and validation sets (n=70). OVH was confirmed in 51 and 23 participants in the training and validation sets during 2-year follow-up period, respectively. Spleen, total liver, right lobe, caudate lobe, left lateral lobe, and left medial lobe volumes, together with diameters of maximum OV and portal venous system were measured on MRI. In the training set, univariate analyses and binary logistic regression analyses were conducted to determine independent predictors. The performance of the model for predicting OVH constructed based on independent predictors from the training set was evaluated with receiver operating characteristic (ROC) analysis and validated in the validation set. The model for predicting OVH was established based on right liver lobe volume and diameters of the maximum OV, left gastric vein, and portal vein [odds ratio (OR) =0.991, 2.462, 1.434, and 1.582, respectively; all P values <0.05]. The logistic regression model equation [-0.009 × right liver lobe volume + 0.901 × maximum OV diameter (MOVD) + 0.361 × left gastric vein diameter (LGVD) + 0.459 × portal vein diameter (PVD) - 7.842] with a cutoff value of -0.656 for predicting OVH obtained excellent performance with an area under ROC curve (AUC) of 0.924 [95% confidence interval (CI): 0.878-0.971]. The Delong test showed negative statistical difference in the model performance between the training and validation sets, with a P value >0.99. The model could help well screen those patients at high risk of OVH for timely intervention and avoiding the fatal complications.

Prevalence, clinical characteristics, and outcomes of spontaneous portosystemic shunt in patients with hepatitis B-related cirrhosis: A multicenter study from China

The impact of spontaneous portosystemic shunt (SPSS) on decompensated events and mortality for patients with hepatitis B-related cirrhosis remains poorly investigated.To evaluate the prevalence, clinical characteristics, and outcomes of SPSS among patients with hepatitis B-related cirrhosis.Patients who were diagnosed with hepatitis B-related cirrhosis were retrospectively recruited. All eligible patients were classified into SPSS and non-SPSS groups and their clinical characteristics and outcomes were compared and analyzed.Of the 1282 patients included in this study, SPSS was identified in 488 patients (38.1%). SPSS group had more severe liver function impairment, higher prevalence and severity of esophageal and gastric varices (EGV), and a higher prevalence of EGV bleeding (EGVB), portal vein thrombosis (PVT), hepatic encephalopathy (HE), ascites, and hepatocellular carcinoma (HCC, all P<0.05). During the follow-up period, SPSS group experienced a significantly higher incidence of EGVB, PVT, and HE (all P<0.05); however, there was no significant difference in the incidence of ascites, HCC, and mortality between the two groups (all P>0.05).With hepatitis B-related cirrhosis, SPSS was common and characterized by severe liver damage and a high prevalence of decompensated events. Moreover, patients with SPSS had higher risks of EGVB, PVT, and HE.

Uncovering the immune microenvironment and molecular subtypes of hepatitis B-related liver cirrhosis and developing stable a diagnostic differential model by machine learning and artificial neural networks.

Background: Hepatitis B-related liver cirrhosis (HBV-LC) is a common clinical disease that evolves from chronic hepatitis B (CHB). The development of cirrhosis can be suppressed by pharmacological treatment. When CHB progresses to HBV-LC, the patient's quality of life decreases dramatically and drug therapy is ineffective. Liver transplantation is the most effective treatment, but the lack of donor required for transplantation, the high cost of the procedure and post-transplant rejection make this method unsuitable for most patients. Methods: The aim of this study was to find potential diagnostic biomarkers associated with HBV-LC by bioinformatics analysis and to classify HBV-LC into specific subtypes by consensus clustering. This will provide a new perspective for early diagnosis, clinical treatment and prevention of HCC in HBV-LC patients. Two study-relevant datasets, GSE114783 and GSE84044, were retrieved from the GEO database. We screened HBV-LC for feature genes using differential analysis, weighted gene co-expression network analysis (WGCNA), and three machine learning algorithms including least absolute shrinkage and selection operator (LASSO), support vector machine recursive feature elimination (SVM-RFE), and random forest (RF) for a total of five methods. After that, we constructed an artificial neural network (ANN) model. A cohort consisting of GSE123932, GSE121248 and GSE119322 was used for external validation. To better predict the risk of HBV-LC development, we also built a nomogram model. And multiple enrichment analyses of genes and samples were performed to understand the biological processes in which they were significantly enriched. And the different subtypes of HBV-LC were analyzed using the Immune infiltration approach. Results: Using the data downloaded from GEO, we developed an ANN model and nomogram based on six feature genes. And consensus clustering of HBV-LC classified them into two subtypes, C1 and C2, and it was hypothesized that patients with subtype C2 might have milder clinical symptoms by immune infiltration analysis. Conclusion: The ANN model and column line graphs constructed with six feature genes showed excellent predictive power, providing a new perspective for early diagnosis and possible treatment of HBV-LC. The delineation of HBV-LC subtypes will facilitate the development of future clinical treatment of HBV-LC.

Early occurrence of acute myelomonocytic leukemia (M4/M5) after liver transplantation: a case report

IntroductionAcute myeloid leukemia is a rare event in post-liver-transplantation recipients. In the present report, we described a case of extramedullary acute myeloid leukemia, M4/M5 subtype, following orthotopic liver transplant.Case presentationThe patient was a 50-year-old Iranian woman who underwent orthotopic liver transplant due to hepatitis B-related cirrhosis (Child C, MELD (model for end-stage liver disease score) = 22). Orthotopic liver transplant was performed using the piggy back technique in January 2022. Induction immunosuppressive therapy was 1 gm methylprednisolone for 3 days followed by a triple maintenance immunosuppressive regimen including mycophenolate mofetil, prednisolone, and tacrolimus. About 5 months after orthotopic liver transplant in June 2022, the patient presented with leukocytosis, with white blood cell count of 99.4 × 103/µl, and physical examination revealed only cervical lymphadenopathy. Biopsy of cervical lymph nodes showed a myeloid tumor. She was immediately hospitalized. Eight hours after hospitalization, the patient gradually developed lethargy and decreased O2 saturation to approximately 89%. Flow cytometry demonstrated the markers of a myelomonocytic acute myeloid leukemia (M4/M5). Cytoreduction was immediately started by intensive leukopheresis followed by induction therapy. Because of a septic complication during the induction therapy, further chemotherapy was discontinued and broad-spectrum antibiotics and antifungal treatments started. Unfortunately, our patient died of severe septic shock 42 days after hospitalization.ConclusionAcute myeloid leukemia is a rare phenomenon after liver transplantation, and it can follow a rapidly fatal clinical course.

A Practical Model for Predicting Esophageal Variceal Rebleeding in Patients with Hepatitis B-Associated Cirrhosis.

Variceal rebleeding is a significant and potentially life-threatening complication of cirrhosis. Unfortunately, currently, there is no reliable method for stratifying high-risk patients. Liver stiffness measurements (LSM) have been shown to have a predictive value in identifying complications associated with portal hypertension, including first-time bleeding. However, there is a lack of evidence to confirm that LSM is reliable in predicting variceal rebleeding. The objective of our study was to evaluate the ability of generating a extreme gradient boosting (XGBoost) algorithm model to improve the prediction of variceal rebleeding. This retrospective analysis examined a cohort of 284 patients with hepatitis B-related cirrhosis. XGBoost models were developed using laboratory data, LSM, and imaging data to predict the risk of rebleeding in the patients. In addition, we compared the XGBoost models with traditional logistic regression (LR) models. We evaluated and compared the two models using the area under the receiver operating characteristic curve (AUROC) and other model performance parameters. Lastly, we validated the models using nomograms and decision curve analysis (DCA). During a median follow-up of 66.6 weeks, 72 patients experienced rebleeding, including 21 (7.39%) and 61 (21.48%) patients who rebleed within 6 weeks and 1 year, respectively. In brief, the AUC of the LR models in predicting rebleeding at 6 weeks and 1 year was 0.828 (0.759-0.897) and 0.799 (0.738-0.860), respectively. In contrast, the accuracy of the XGBoost model in predicting rebleeding at 6 weeks and 1 year was 0.985 (0.907-0.731) and 0.931 (0.806-0.935), respectively. LSM and high-density lipoprotein (HDL) levels differed significantly between the rebleeding and nonrebleeding groups, with LSM being a reliable predictor in those models. The XGBoost models outperformed the LR models in predicting rebleeding within 6 weeks and 1 year, as demonstrated by the ROC and DCA curves. The XGBoost algorithm model can achieve higher accuracy than the LR model in predicting rebleeding, making it a clinically beneficial tool. This implies that the XGBoost model is better suited for predicting the risk of esophageal variceal rebleeding in patients.
