RESUMEN
Background/Aims: To study the association of infertility in patients with Budd Chiari syndrome, radiological aspects of the disease determining infertility and to see if there are improved chances of conception following radiological intervention. Methods: Retrospective search of the hospital records was done and patients with Budd Chiari syndrome, who underwent radiological intervention between January 2016 till October 2021 were initially included. Patients outside the reproductive age group, unmarried patients, patients who did not attempt conception or attempted for less than 1 year and patients having other causes of infertility were excluded. 90 patients were assessed for presence of primary or secondary infertility using infertility questionnaire. In patients with infertility, conception during 1-year follow-up period following radiological intervention, was assessed. Results: 146 patients underwent radiological intervention for Budd Chiari syndrome in the study period. 56 patients meeting the exclusion criteria were excluded from the study and subsequently 90 patients were assessed for infertility. 16.7% (15/90) of our patients with Budd Chiari syndrome had infertility, of which 7 were male, and 8 were female. Infertility is more common in younger age group (mean - 28.8 ± 4.2 years) (P < 0.001). In females, presence of pelvic venous congestion on preprocedural imaging showed significant association with infertility (P < 0.001). 6 (40%) out of 15 of patients with infertility conceived during a 1-year follow-up period after radiological intervention. Conclusion: Infertility is a common in patients with Budd Chiari syndrome, with a prevalence of 16.7%. Pelvic venous congestion is associated with women having infertility. Radiological interventions play important role in management of Budd Chiari and may help to overcome infertility in these patients.
RESUMEN
Gut metabolites via the portal vein affect several liver functions, including regeneration. Here, we investigated gut microbiota-derived metabolites in portal and peripheral serum during liver regeneration. We developed rat models of 70% partial hepatectomy (PHx) with and without prior gut microbiota modulation by three-week antibiotic (Abx) treatment. Sham without Abx were used as controls and compared to sham with Abx. Liver regeneration at day 2 following PHx was assessed by expression of proliferating cell nuclear antigen (PCNA) protein in liver tissues and cyclin genes in primary hepatocytes. High pressure liquid chromatography-mass spectrometry (HPLC-MS) based portal and peripheral venous serum metabolomics was performed to identify differentially altered metabolites (DAMs). Compared to controls, rat livers at day 2 post-PHx showed significant upregulation in the average number of PCNA-positive cells, which positively correlated with the expression of cell cycle genes in hepatocytes. In Abx-treated PHx, we observed reduced PCNA-positivity and downregulation in gene expression of various cyclins in hepatocytes compared to PHx. We identified 224 DAMs between controls vs PHx and 189 DAMs between Abx-treated PHx vs PHx in portal serum. Many common DAMs showed opposite expression trends in PHx vs controls and then Abx+PHx vs PHx in portal serum, such as sphingosine-1-phosphate and deoxycholic acid. In vitro studies with deoxycholic acid demonstrated that it enhanced the viability and proliferation of primary hepatocytes and hepatocyte organoids. The study underscores the critical role of deoxycholic acid in portal blood in enhancing hepatocyte proliferation and subsequently, liver regeneration.
RESUMEN
BACKGROUND: Propranolol, a non-selective beta-blocker, commonly used to prevent variceal bleed, but might precipitate circulatory dysfunction in severe ascites. Midodrine, an alpha-1 adrenergic agonist improves renal perfusion and systemic hemodynamics. Addition of midodrine might facilitate higher maximum tolerated dose (MTD) of propranolol, thereby less risk of variceal bleed in cirrhosis patients with severe ascites. METHODS: 140 patients with cirrhosis and severe/refractory ascites were randomized- propranolol and midodrine (Gr.A,n = 70) or propranolol alone (Gr.B,n = 70). Primary outcome was incidence of bleed at 1 year. Secondary outcomes included ascites control, achievement of target heart rate (THR), HVPG response and adverse effects. RESULTS: Baseline characteristics were comparable between two groups. Cumulative incidence of bleed at 1 year was lower in Gr.A than B (8.5%vs.27.1%,p-0.043). The MTD of propranolol was higher in Gr.A (96.67 ± 36.6 mg vs. 76.52 ± 24.4 mg; p-0.01) and more patients achieved THR (84.2%vs.55.7%,p-0.034). Significantly higher proportion of patients in Gr.A had complete resolution of ascites [17.1%vs.11.4%,p-0.014), diuretic tolerance (80%vs.60%,p-0.047) at higher doses(p-0.02) and lesser need for paracentesis. Patients in Gr.A also had greater reduction in variceal grade (75.7%vs.55.7%;p-0.01), plasma renin activity (54.4% from baseline) (p = 0.02). Mean HVPG reduction was greater in Gr.A than B [4.38 ± 2.81 mmHg(23.5%) vs. 2.61 ± 2.87 mmHg(14.5%),p-0.045]. Complications like post-paracentesis circulatory dysfunction and spontaneous bacterial peritonitis on follow-up were higher in Gr.B than A (22.8%vs.51.4%,p = 0.013 and 10%vs.15.7%, p = 0.03, respectively). CONCLUSION: Addition of midodrine facilitates effective use of propranolol in higher doses and greater HVPG reduction, thereby preventing first variceal bleed, reduced paracentesis requirements with fewer ascites- related complications in patients with cirrhosis with severe/refractory ascites.

BACKGROUND AND AIMS: Alcohol-associated hepatitis (AH) poses significant short-term mortality. Existing prognostic models lack precision for 90-day mortality. Utilizing artificial intelligence in a global cohort, we sought to derive and validate an enhanced prognostic model. APPROACH AND RESULTS: The Global AlcHep initiative, a retrospective study across 23 centers in 12 countries, enrolled patients with AH per National Institute for Alcohol Abuse and Alcoholism criteria. Centers were partitioned into derivation (11 centers, 860 patients) and validation cohorts (12 centers, 859 patients). Focusing on 30 and 90-day postadmission mortality, 3 artificial intelligence algorithms (Random Forest, Gradient Boosting Machines, and eXtreme Gradient Boosting) informed an ensemble model, subsequently refined through Bayesian updating, integrating the derivation cohort's average 90-day mortality with each center's approximate mortality rate to produce posttest probabilities. The ALCoholic Hepatitis Artificial INtelligence Ensemble score integrated age, gender, cirrhosis, and 9 laboratory values, with center-specific mortality rates. Mortality was 18.7% (30 d) and 27.9% (90 d) in the derivation cohort versus 21.7% and 32.5% in the validation cohort. Validation cohort 30 and 90-day AUCs were 0.811 (0.779-0.844) and 0.799 (0.769-0.830), significantly surpassing legacy models like Maddrey's Discriminant Function, Model for End-Stage Liver Disease variations, age-serum bilirubin-international normalized ratio-serum Creatinine score, Glasgow, and modified Glasgow Scores ( p < 0.001). ALCoholic Hepatitis Artificial INtelligence Ensemble score also showcased superior calibration against MELD and its variants. Steroid use improved 30-day survival for those with an ALCoholic Hepatitis Artificial INtelligence Ensemble score > 0.20 in both derivation and validation cohorts. CONCLUSIONS: Harnessing artificial intelligence within a global consortium, we pioneered a scoring system excelling over traditional models for 30 and 90-day AH mortality predictions.

RESUMEN
End-stage liver disease (ESLD) is a life-threatening clinical syndrome and when complicated with infection the mortality is markedly increased. In patients with ESLD, bacterial or fungal infection can induce or aggravate the occurrence or progression of liver decompensation. Consequently, infections are among the most common complications of disease deterioration. There is an overwhelming need for standardized protocols for early diagnosis and appropriate management for patients with ESLD complicated by infections. Asia Pacific region has the largest number of ESLD patients, due to hepatitis B and the growing population of alcohol and NAFLD. Concomitant infections not only add to organ failure and high mortality but also to financial and healthcare burdens. This consensus document assembled up-to-date knowledge and experience from colleagues across the Asia-Pacific region, providing data on the principles as well as evidence-based current working protocols and practices for the diagnosis and treatment of patients with ESLD complicated by infections.

BACKGROUND AND AIMS: Patients with Child-Turcotte-Pugh class B and C cirrhosis with upper gastrointestinal bleeding (UGIB) have systemic as well as localized (in the mucosa of the esophagus and stomach) fibrinolysis. The aim of this study was to evaluate the efficacy and safety of tranexamic acid in the treatment of acute UGIB in patients with cirrhosis. APPROACH AND RESULTS: A total of 600 patients with advanced liver cirrhosis (Child-Turcotte-Pugh class B or C) presenting with UGIB were randomly allocated to either the tranexamic acid (n=300) or the placebo group (n=300). The primary outcome measure was the proportion of patients developing 5-day treatment failure. Failure to control bleeding by day 5 was seen in 19/300 (6.3%) patients in the tranexamic acid group and 40/300 (13.3%) patients in the placebo group ( p =0.006). Esophageal endoscopic variceal ligation (EVL) site as a source of failure to control bleeding by day 5 among patients undergoing first-time esophageal EVL (excluding patients with a previous post-EVL ulcer as a source of bleed) was seen in 11/222 (4.9%) patients in the tranexamic acid group and 27/225 (1212.0%) patients in the placebo group ( p =0.005). However, 5-day and 6-week mortality was similar in the tranexamic acid and placebo groups. CONCLUSIONS: Tranexamic acid significantly reduces the failure to control bleeding by day 5 and failure to prevent rebleeding after day 5 to 6 weeks in patients with advanced liver cirrhosis (Child-Turcotte-Pugh class B or C) presenting with UGIB, by preventing bleeding from the EVL site.

BACKGROUND: Post-transjugular intrahepatic portosystemic shunt (TIPS) liver failure (PTLF) is a serious complication of TIPS procedure with poor patient prognosis. This study tried to investigate the incidence of PTLF following elective TIPS procedure and evaluated possible predictive factors for the same. METHODS: A retrospective analysis of patients who underwent elective TIPS placement between 2012 and 2022 and was conducted to determine development of PTLF (≥ 3-fold bilirubin and/or ≥ 2-fold INR elevation from the baseline) within 30 days following TIPS procedure. Medical record review was done and factors predicting development of PTLF and the 90-day transplant-free survival was determined. RESULTS: Thirty of 352 (8.5%) patients developed PTLF within 30 days of TIPS (mean age 54.2 ± 9.8 years, 83% male). The etiology of cirrhosis was related to non-alcoholic steatohepatitis (NASH) in 50%, alcohol in 33.3%, and hepatitis B/C virus infection in 16.7% of the patients. The mean Child-Turcotte-Pugh (CTP) score was 9.5 ± 1.2 and mean model for end stage liver disease (MELD) score was 14.6 ± 4.5 at the time of admission in patients who developed PTLF. The indication for TIPS was recurrent variceal bleed in 50% (15 of 30) and refractory ascites in 46.7% (14 of 30) patients with PTLF. Multivariate analysis identified prior HE (OR 6.1; CI 2.57-14.5, p < 0.0001) and higher baseline CTP score (OR 1.47; CI 1.07-2.04; p = 0.018) as predictors of PTLF. PTLF was associated with significantly lower 90-day transplant-free survival, as compared to patients without PTLF (40% versus 96%, p < 0.001). CONCLUSION: Almost 10% of patients with cirrhosis develop post-TIPS liver failure and is associated with significant early mortality and morbidity. Higher baseline CTP score and prior HE were identified as predictors for PTLF.

High HBV DNA levels predispose to mother to child transmission (MTCT) of HBV. Early nucleotide analogue (NA) therapy can reduce HBV DNA and minimize MTCT. We analysed immune-metabolic profile in pregnant mothers who received NA from 2nd trimester compared with untreated mothers. In 2nd trimester, there was no difference in immune profiles between Gr.1 and Gr.2 but high viral load women had downregulated pyruvate, NAD+ metabolism but in 3rd trimester, Gr.1 had significant reduction in HBV-DNA, upregulated pyruvate and NAD with increased IFN-2αA, CD8Tcells, NK cells and decreased Tregs, IL15, IL18, IL29, TGFß3 compared to Gr.2. In Gr.1, three eAg-ve women showed undetectable DNA and HBsAg. At delivery, Gr.1 showed no MTCT, with undetectable HBV DNA, HBsAg, high CD8 and NK cells in two women. We conclude, that starting NA from second trimester, reduces HBV load and MTCT, modulates NAD, induces immunity and suggest use of NA in early gestation in future trials.

BACKGROUND: Severe alcohol-associated hepatitis (SAH) presenting as acute-on-chronic liver failure (ACLF) has high mortality. Severe hepatic inflammation and ongoing hepatocellular cell death lead to rapid rise in portal pressure, a hyperdynamic circulation that might precipitate infections and organ failures. METHODS: Consecutive SAH patients were classified based on baseline HVPG measurement as 6to < 12 mmHg, 12to < 20 mmHg, and ≥ 20 mmHg. We analyzed portal hypertension severity in relation to fibrosis stage, ACLF at presentation, response to prednisolone, severity scores(MELD and Maddrey's Discriminant Function, mDF), and 90-day mortality. RESULTS: Of 819 SAH patients (94.6% ACLF, 85.4% histological cirrhosis, median MELD and mDF scores 25 and 66, respectively), 250(30.5%) had HVPG ≥ 20 mmHg. Patients with HVPG ≥ 20 mmHg more often had large esophageal varices (25.2%vs.13.2%; p-0.001), higher baseline MELD (27.1 ± 5.6vs.25.3 ± 5.2; p-0.001), and mDF(76.1 ± 16vs.68.4 ± 15.1; p-0.01) scores. No patient without ACLF had HVPG ≥ 20 mmHg. Moreover, during hospital course these patients had higher incidence of variceal bleed (17.2%vs.8.8%; p-0.001), acute kidney injury (36.4%vs.25.3%; p-0.001), and spontaneous bacterial peritonitis (6.4%vs.3.5%; p-0.05). Of 412(50.3%) eligible patients treated with prednisolone, 69.2% showed response at day 7(Lille's score < 0.45). 90-day mortality was 27.6%; and baseline MELD > 25.5[HR 1.78], HVPG ≥ 20 mmHg [HR 1.86], the presence of HE[HR 1.63], and prednisolone ineligibility due to sepsis[HR 1.27] were independent predictors. Mortality was unrelated to varices grade, variceal bleed, and histological cirrhosis. Repeat HVPG performed in 114(19.2%) patients after a median of 5.2 months showed significant decrease (3.6 mmHg; p-0.001) which correlated with improvement in MELD score(13points; p-0.05). CONCLUSION: Development of ACLF and complications in SAH are likely a result of acute rise in HVPG. "High-risk" SAH are SAH patients with HVPG ≥ 20 mmHg in the presence of ascites. Understanding the drivers for acute rise in portal pressure in SAH ACLF might help introduction of newer therapies.

BACKGROUND & AIMS: Widespread use of direct-acting antivirals for hepatitis C virus infection has been paralleled with increased numbers of patients with hepatocellular carcinoma (HCC) after achieving sustained virologic response (post-SVR HCC) worldwide. Few data compare regional differences in the presentation and prognosis of patients with post-SVR HCC. METHODS: We identified patients with advanced fibrosis (F3/F4) who developed incident post-SVR HCC between March 2015 and October 2021 from 30 sites in Europe, North America, South America, the Middle East, South Asia, East Asia, and Southeast Asia. We compared patient demographics, liver dysfunction, and tumor burden by region. We compared overall survival by region using Kaplan-Meier analysis and identified factors associated with survival using multivariable Cox regression analysis. RESULTS: Among 8796 patients with advanced fibrosis or cirrhosis who achieved SVR, 583 (6.6%) developed incident HCC. There was marked regional variation in the proportion of patients detected by surveillance (range: 59.5%-100%), median maximum tumor diameter (range, 1.8-5.0 cm), and the proportion with multinodular HCC (range, 15.4%-60.8%). The prognosis of patients highly varied by region (hazard ratio range, 1.82-9.92), with the highest survival rates in East Asia, North America, and South America, and the lowest survival rates in the Middle East and South Asia. After adjusting for geographic region, HCC surveillance was associated with early stage detection (Barcelona Clinic Liver Cancer stage 0/A, 71.0% vs 21.3%; P < .0001) and lower mortality rates (adjusted hazard ratio, 0.29; 95% CI, 0.18-0.46). CONCLUSIONS: Clinical characteristics, including early stage detection, and prognosis of post-SVR HCC differed significantly across geographic regions. Surveillance utilization appears to be a high-yield intervention target to improve prognosis among patients with post-SVR HCC globally.

Background and aims: A high proportion of hepatitis B e antigen (HBeAg)-negative chronic hepatitis B (CHB) patients develop clinical relapse after stopping long-term nucleotide analogues (NAs). The aim of this study was to assess the efficacy of pegylated interferon (PEG-IFN) alpha 2b in inducing hepatitis B surface antigen (HBsAg) loss in such patients. Methods: NAs were stopped in 118 HBeAg-negative CHB patients fulfilling the Asian Pacific Association for the Study of Liver (APASL) 2015 criteria for stopping NAs; they had received NAs for a median interquartile range (IQR) of 60 (48-84) months. Results: Overall, 82 of 118 (69.5%) patients developed clinical relapse after stopping NAs; 44 within 12 months (and treated with PEG-IFN alpha 2b 1.5 mcg/kg weekly subcutaneous injections for 48 weeks); and 38 after 12 months [and treated with tenofovir alafenamide fumarate (TAF) 25 mg daily] of follow-up. The decision to treat with either PEG-IFN or TAF was not a time-bound decision but was due to logistical problems.During the median IQR follow-up of 48 (43.5-52.5) months after the start of PEG-IFN, 14 of 44 (31.8%) patients developed clinical relapse after stopping PEG-IFN and were started on TAF. At the last follow-up visit, HBsAg was found to be negative in 7/44 (15.9%) of patients receiving PEG-IFN.Among 38 patients treated with TAF for clinical relapse, during the median IQR follow-up of 18 (12-30) months after start of TAF, no patient became HBsAg negative.36 patients did not develop clinical relapse during the follow-up, and after a median IQR follow-up of 60 (60-60) months after stopping NAs, HBsAg negative was found in 1/36 (2.8%) of patient at the last follow-up. Conclusions: Among patients with HBeAg-negative chronic hepatitis B who developed clinical relapse after stopping long-term NAs therapy and were subsequently treated with PEG-IFN alpha 2b, 15.9% achieved HBsAg loss on long-term follow-up.
RESUMEN
Background: We conducted a systematic review and meta-analysis to study the association between non-alcoholic fatty liver disease (NAFLD) and incident cardiovascular disease (CVD). Methods: We searched Medline, Embase, Cochrane database and TRIP database. Random-effects model meta-analyses were used to obtain pooled effect sizes and 95% confidence intervals. The certainty in evidence was rated using the GRADE tool. Results: Altogether 36 studies including a total of 7,068,007 participants were included in the systematic review and meta-analysis. Pooled data from 19 cohort studies demonstrated a significant increase in the risk of non-fatal CVD events in patients with NAFLD (HR 1.57, 95% CI 1.33-1.85, I2 = 95%). Pooled data from eight studies showed a significant increase in fatal CVD (HR 1.40, 95% CI 1.24-1.57, I2 =27%), and eight cohort studies suggested a significant increase in combined non-fatal and fatal CVD (HR 1.41, 95% CI 1.13-1.76, I2 =80%). Meta-analysis of studies reporting adjusted estimates in NAFLD patients with fibrosis revealed a significant increase in CVD events with acceptable level of heterogeneity (HR 1.64, 95% CI 1.25-2.16, I2 = 31%). The anticipated absolute increase in the risk of combined fatal and non-fatal CVD was estimated to be 29 more per thousand with NAFLD; that of fatal CVD events 16 more per thousand and that of non-fatal CVD events 19 more per thousand with NAFLD. The GRADE rating ranged from very low to low for overall and subgroup analyses. Conclusion: The present systematic review suggests that NAFLD increases the risk of incident CVD. Cohort studies with the ability to analyze subgroup effects based on severity, along with randomized controlled trials that provide experimental evidence demonstrating a decrease in cardiovascular disease events through the treatment of non-alcoholic fatty liver disease, are necessary to validate and reinforce these findings.
RESUMEN
Pregnancy being an immune compromised state, coronavirus disease of 2019 (COVID-19) disease poses high risk of premature delivery and threat to fetus. Plasma metabolome regulates immune cellular responses, therefore we aimed to analyze the change in plasma secretome, metabolome, and immune cells with disease severity in COVID-19 positive pregnant females and their cord blood. COVID-19 reverse transcriptase-polymerase chain reaction positive pregnant females (n = 112) with asymptomatic (Asy) (n = 82), mild (n = 21), or moderate (n = 9) disease, healthy pregnant (n = 18), COVID-19 positive nonpregnant females (n = 7) were included. Eighty-two cord blood from COVID-19 positive and seven healthy cord blood were also analyzed. Mother's peripheral blood and cord blood were analyzed for untargeted metabolome profiling and cytokines by using high-resolution mass spectrometry and cytokine bead array. Immune scan was performed only in mothers' blood by flow cytometry. In Asy severe acute respiratory syndrome coronavirus 2 infection, the amino acid metabolic pathways such as glycine, serine, l-lactate, and threonine metabolism were upregulated with downregulation of riboflavin and tyrosine metabolism. However, with mild-to-moderate disease, the pyruvate and nicotinamide adenine dinucleotide (NAD+ ) metabolism were mostly altered. Cord blood mimicked the mother's metabolomic profiles by showing altered valine, leucine, isoleucine, glycine, serine, threonine in Asy and NAD+ , riboflavin metabolism in mild and moderate. Additionally, with disease severity tumor necrosis factor-α, interferon (IFN)-α, IFN-γ, interleukin (IL)-6 cytokine storm, IL-9 was raised in both mothers and neonates. Pyruvate, NAD metabolism and increase in IL-9 and IFN-γ had an impact on nonclassical monocytes, exhausted T and B cells. Our results demonstrated that immune-metabolic interplay in mother and fetus is influenced with increase in IL-9 and IFN-γ regulated pyruvate, lactate tricarboxylic acid, and riboflavin metabolism with context to disease severity.

Background: Seizures are reported in about one-third of patients with severe liver disease in association with acute or chronic liver failure. The majority of the seizures are of focal type. Occasionally generalized tonic-clonic seizures are seen when there is ethanol withdrawal. Not much is known about ictal blinking (IB) in severe liver disease. IB is the rare form of seizures and was reported in severe liver disease recently from this institute. Oculogyric crisis (OGC) is rarely reported in relation to the severe liver disease. OGC was also noted first time in our intensive care unit. Methods: At the Institute of Liver and Biliary Sciences (ILBS), data on patients with IB and OGC were analyzed from October 2018 to January 2023 (52 months). All the patients had video electroencephalograph (video-EEG) recording after proper permission/consent. The patients were followed up later for the course of the illness. Results: A total of 16 (12M:4F) patients were seen. Majority 12 (75%) were IB and 3 OGC. EEG was abnormal in nine (75.0%) of IB patients. Brain imaging had nonspecific findings. The outcome was based on the severity and recovery of the underlying liver disease. Conclusions: Unusual facial movements in the form of IB and OGC are reported, which are most of the time missed. This report highlights the importance of recognition of these events and proper in time management to improve the outcome.
RESUMEN
Introduction: This article aims to evaluate the prognostic significance of pretreatment serum ɣ-glutamyl transpeptidase (GGT) levels in patients with intermediate (BCLC B) and advanced stage (BCLC C) hepatocellular carcinoma receiving transarterial chemoembolization (TACE) as first-line treatment. Methods: In this single-center retrospective study, a total of 608 patients with BCLC B and BCLC C class were included who received TACE as first-line treatment modality. Patients were divided into low and high GGT groups based on a cutoff value of pretreatment serum GGT levels calculated by receiver operating curve. Overall survival was evaluated with Kaplan-Meier method, and intergroup significance was calculated by log-rank test for overall patients, each BCLC B and BCLC C group. Univariate and multivariate analysis were used for significance for prognostic factors. Results: Median follow-up time was 20, 22, and 9 months for overall patients, BCLC B, and BCLC C group, respectively. Optimal cut value for GGT was calculated at 90.5 U/L. One-year and 3-year survival rates were 84.2% and 27.9% in low GGT, 49.4% and 8.6% in high-GGT group for overall patients. Multivariate analysis in overall patients showed Child-Pugh B (HR,1.801; 95%CI, 1.373-2.362, P < .001), ascites (1.393, 1.070-1.812; P = .014), multiple tumors (1.397, 1.137-1.716; P = .001), AST >40 (1.407, 1.095-1.808; P = .008), albumin <3.2 (.735, .612-.884; P = .001), AFP > 400 (1.648, 1.351-2.011; P < .001), high GGT (2.009, 1.631-2.475; P < .001), or receipt of chemo/ablation (.463, .377-.569; P < .001) as independent risk factors for overall survival. Serum GGT levels and AFP showed significant correlation in between with significance coefficient of .155 (P < .001). Conclusion: Elevated pretreatment serum GGT level was feasible and promising independent prognostic marker for overall survival in intermediate and advanced stage hepatocellular carcinoma patients treated with TACE.
RESUMEN
BACKGROUND: GCSF may improve the prognosis of severe liver disease by promoting liver regeneration and immune restoration. Our Aim was to investigate its controversial efficacy in decompensated cirrhosis, acute alcoholic hepatitis (AAH), or acute-on-chronic liver failure (ACLF) through meta-analysis. METHODS: Meta-analysis of proportions (random effect model) including 19 RCTs (1287 patients from 16 Asian and 3 European studies including 487 ACLF, 231 AAH and 569 cirrhotic patients) evaluating survival at day-28, day-90, 6 months, one year, and/or occurrence of sepsis as major outcomes. RESULTS: In patients with decompensated cirrhosis, G-CSF administration was associated with a reduction in the weight-adjusted risk of mortality of 9% at day-90 (OR=0.33; 95%CI: 0.18-0.58; p = 0.0002), 16% at 6 months (OR=0.31; 95%CI: 0.15-0.62; p = 0.0009), 26% at one year (OR=0.21; 95%CI:0.12-0.38, p<0.0001) and a weight-adjusted 28% risk reduction for sepsis (OR=0.28; 95%CI: 0.16-0.49; p<0.0001). Only Asian studies were positive. In AAH, G-CSF was associated with an 18% reduction in weight-adjusted mortality risk at day-28 (OR=0.31; 95%CI:0.11-0.83, p = 0.021), 32% at day-90 (OR=0.20; 95%CI:0.09-0.46, p<0.0001) and a weight-adjusted 42% risk reduction for sepsis (OR=0.17; 95%CI: 0.08-0.38; p<0.0001). Only Asian studies, in which corticosteroids were not given systematically in case of severe AAH, were positive. In patients with ACLF, the results on mortality at day-28 were heterogeneous, and GCSF had no beneficial effect on sepsis or survival at day-90. CONCLUSION: G-CSF may be effective in patients with decompensated cirrhosis or AAH by reducing the occurrence of sepsis and mortality. Further meta-analyses of individual data, or new, powerful and methodologically flawless therapeutic trials, are warranted to confirm these results, which harbor wide divergences between Asian and European RCTs.

Background & Aims: Lymphatic vessels (LVs) are crucial for maintaining abdominal fluid homoeostasis and immunity. In cirrhosis, mesenteric LVs (mLVs) are dilated and dysfunctional. Given the established role of vascular endothelial growth factor-C (VEGF-C) in improving LVs, we hypothesised that VEGF-C treatment could ameliorate the functions of mLVs in cirrhosis. Methods: In this study, we developed a nanoformulation comprising LV-specific growth factor, recombinant human VEGF-C (Cys156Ser) protein (E-VEGF-C) and delivered it orally in different models of rat cirrhosis to target mLVs. Cirrhotic rats were given nanoformulation without VEGF-C served as vehicles. Drainage of mLVs was analysed using tracer dye. Portal and systemic physiological assessments and computed tomography were performed to measure portal pressures and ascites. Gene expression and permeability of primary mesenteric lymphatic endothelial cells (LyECs) was studied. Immune cells in mesenteric lymph nodes (MLNs) were quantified by flow cytometry. Endogenous and exogenous gut bacterial translocation to MLNs was examined. Results: In cirrhotic rats, mLVs were dilated and leaky with impaired drainage. Treatment with E-VEGF-C induced proliferation of mLVs, reduced their diameter, and improved functional drainage. Ascites and portal pressures were significantly reduced in E-VEGF-C rats compared with vehicle rats. In MLNs of E-VEGF-C animals, CD8+CD134+ T cells were increased, whereas CD25+ regulatory T cells were decreased. Both endogenous and exogenous bacterial translocation were limited to MLNs in E-VEGF-C rats with reduced levels of endotoxins in ascites and blood in comparison with those in vehicle rats. E-VEGF-C treatment upregulated the expression of vascular endothelial-cadherin in LyECs and functionally improved the permeability of these cells. Conclusions: E-VEGF-C treatment ameliorates mesenteric lymph drainage and portal pressure and strengthens cytotoxic T-cell immunity in MLNs in experimental cirrhosis. It may thus serve as a promising therapy to manage ascites and reduce pathogenic gut bacterial translocation in cirrhosis. Impact and Implications: A human recombinant pro-lymphangiogenic growth factor, VEGF-C, was encapsulated in nanolipocarriers (E-VEGF-C) and orally delivered in different models of rat liver cirrhosis to facilitate its gut lymphatic vessel uptake. E-VEGF-C administration significantly increased mesenteric lymphatic vessel proliferation and improved lymph drainage, attenuating abdominal ascites and portal pressures in the animal models. E-VEGF-C treatment limited bacterial translocation to MLNs only with reduced gut bacterial load and ascitic endotoxins. E-VEGF-C therapy thus holds the potential to manage ascites and portal pressure and reduce gut bacterial translocation in patients with cirrhosis.
