Abstract
Background Acute-on-chronic hepatitis B liver failure (ACHBLF) is a clinical syndrome with an extremely high mortality. In this study, we aim to evaluate the potential role of serum exosomal long noncoding RNA (lncRNA) growth arrest-specific 5 (GAS5) in ACHBLF and its predictive value for 3-month mortality. Methods From December 2017 to June 2022, we enrolled 110 patients with ACHBLF and 42 healthy controls (HCs). Exosomes were isolated from the serum of the participants. Serum exosomal lncRNA GAS5 was detected using quantitative real-time polymerase chain reaction (qRT-PCR). The functional role of lncRNA GAS5 on hepatocyte phenotypes was investigated through loss-of-function and gain-of-function assays. Exosomal labeling and cell uptake assay were used to determine the exosomes-mediated transmission of lncRNA GAS5 in hepatocytes in vitro. Results The serum exosomal lncRNA GAS5 was identified to be an independent predictor for 3-month mortality of ACHBLF. It yielded an area under the receiver operating characteristic curve (AUC) of 0.88, which was significantly higher than MELD score (AUC 0.73; P < 0.01). Further study found that lncRNA GAS5 could inhibit hepatocytes proliferation and increase hepatocytes apoptosis. Exosomes-mediated lncRNA GAS5 transfer promoted hepatocytes injury. The knocked down of lncRNA GAS5 weakened H2O2-induced hepatocytes injury. Conclusion We revealed that serum exosomal lncRNA GAS5 might promote hepatocytes injury and showed high predictive value for 3-month mortality in ACHBLF.

Abstract
BACKGROUND Glucocorticoids could greatly improve the prognosis of patients with acute-on-chronic hepatitis B liver failure (ACHBLF). Suppressor of cytokine signaling (SOCS) 1 methylation has been shown to be associated with mortality in ACHBLF. METHODS Eighty patients with ACHBLF were divided into group glucocorticoid (GC) and group conservative medical (CM). Sixty patients with chronic hepatitis B (CHB), and Thirty healthy controls (HCs) served as control group. SOCS1 methylation levels in peripheral mononuclear cells (PBMCs) was detected by MethyLight. RESULTS SOCS1 methylation levels were significantly higher in patients with ACHBLF than those with CHB and HCs (P < 0.01, respectively). Nonsurvivors showed significantly higher SOCS1 methylation levels (P < 0.05) than survivors in both GC and CM groups in ACHBLF patients. Furthermore, the survival rates of the SOCS1 methylation-negative group were significantly higher than that of the methylation-positive group at 1 month (P = 0.014) and 3 months (P = 0.003) follow-up. Meanwhile, GC group and CM group had significantly lower mortality at 3 months, which may be related to application of glucocorticoid. In the SOCS1 methylation-positive group, the 1-month survival rate was significantly improved, which may be related to GC treatment (P = 0.020). However, no significant difference could be observed between the GC group and CM group in the methylation-negative group (P = 0.190). CONCLUSIONS GC treatment could decrease the mortality of ACHBLF and SOCS1 methylation levels might serve as prognostic marker for favorable response to glucocorticoid treatment.

Abstract
Background Early prediction for short-term prognosis is essential for the management of hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF). In this study, we aim to establish a noninvasive model for predicting the 90-day mortality in patients with HBV–ACLF received glucocorticoid therapy. Methods Two hundred and eighty patients with HBV–ACLF were enrolled from July 2010 to June 2022. All patients received routine medicine treatment and 204 of them received additional glucocorticoid treatment. Then, the patients who received glucocorticoid treatment were randomly divided into a training cohort and a validation cohort. An early prediction model for 90-day mortality of HBV–ACLF was established in the training cohort and then validated in the validation cohort. Results HBV–ACLF patients received glucocorticoid treatment showed significantly better survival that those not (P < 0.01). In the training cohort, a noninvasive model was generated with hepatic encephalopathy grade, INR, total bilirubin, age and SIRS status, which was named HITAS score. It showed significantly better predictive value for 90-day mortality of HBV–ACLF than MELD score and Child–Turcotte–Pugh score in both the training cohort and validation cohort. Using the Kaplan–Meier analysis with cutoff points of 2.5 and 3.47, the HITAS score can classify HBV–ACLF patients into different groups with low, intermediate and high risk of death after glucocorticoid therapy. Conclusions We proposed a HITAS score, which was an early prediction model for the prognosis of HBV–ACLF. It might be used to identify HBV–ACLF patients with favorable responses to glucocorticoid treatment.

Abstract
Acute-on-chronic liver failure (ACLF) is a complex clinical syndrome, and patients often have high short-term mortality. It occurs with intense systemic inflammation, often accompanied by a proinflammatory event (such as infection or alcoholic hepatitis), and is closely related to single or multiple organ failure. Liver inflammation begins when innate immune cells (such as Kupffer cells (KCs)) are activated by binding of pathogen-associated molecular patterns (PAMPs) from pathogenic microorganisms or damage-associated molecular patterns (DAMPs) of host origin to their pattern recognition receptors (PRRs). Activated KCs can secrete inflammatory factors as well as chemokines and recruit bone marrow-derived cells such as neutrophils and monocytes to the liver to enhance the inflammatory process. Bacterial translocation may contribute to ACLF when there are no obvious precipitating events. Immunometabolism plays an important role in the process (including mitochondrial dysfunction, amino acid metabolism, and lipid metabolism). The late stage of ACLF is mainly characterized by immunosuppression. In this process, the dysfunction of monocyte and macrophage is reflected in the downregulation of HLA-DR and upregulation of MER tyrosine kinase (MERTK), which weakens the antigen presentation function and reduces the secretion of inflammatory cytokines. We also describe the specific function of bacterial translocation and the gut-liver axis in the process of ACLF. Finally, we also describe the transcriptomics in HBV-ACLF and the recent progress of single-cell RNA sequencing as well as its potential application in the study of ACLF in the future, in order to gain a deeper understanding of ACLF in terms of single-cell gene expression.

Abstract
Liver failure is characterized by serious liver decompensation and high mortality. The activation of systemic immune responses and systemic inflammation are widely accepted as the core pathogenesis of liver failure. Glucocorticoids (GCs) are most regularly utilized to suppress excessive inflammatory reactions and immunological responses. GCs have been used in the clinical treatment of liver failure for nearly 60 years. While there has been no unanimity on the feasibility and application of GC treatment in liver failure until recently. The most recent trials have produced conflicting results when it comes to the dose and time for GC therapy of different etiology of liver failure. Our review outlines the issues and options in managing GC treatment in liver failure based on an investigation of the molecular mechanism that GC may give in the treatment.

JOURNAL OF ETHNOPHARMACOLOGY 2021; 280:114411.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Acute-on-chronic liver failure (ACLF) is a key complication of chronic hepatitis, with a relatively high mortality rate and limited treatment options, which dramatically threatens human lives. Yi-Qi-Jian-Pi formula (YQJPF) is a herbal compound commonly used to treat liver failure. AIM OF THE STUDY The purpose of this research is to discuss the potential molecular biological effect and mechanism of YQJPF in ACLF. MATERIALS AND METHODS In this study, we created a rat model of ACLF by CCl4-, LPS- and D-Galactosamine (D-Gal) and an in vitro model of LPS-induced hepatocyte damage. The specific components of YQJPF and potential mechanism were explored based on bioinformatics analyses. Furthermore, we verified the effect of YQJPF on ACLF using immunohistochemistry, RT-qPCR, western blotting, and flow cytometry. RESULTS Our research demonstrated that, after YQJPF treatment, hepatocyte injury in rats was relieved. Bioinformatics analysis showed that PI3K/AKT, HIF-1, mitochondrial apoptosis pathways played prominent roles. YQJPF promoted HIF-1α protein expression and exerted protective effects against hypoxic injury, simultaneously reducing mitochondrial ROS production, suppressing hepatocyte apoptosis. Furthermore, we showed that YQJPF accelerates PI3K/AKT pathway activation, a known broad-spectrum inhibitor of PI3K. LY294002, which was used for reverse verification, suppressed the effect of YQJPF on hypoxic injury and ROS-mediated hepatocyte apoptosis. CONCLUSIONS YQJPF ameliorates liver injury by suppressing hypoxic injury and ROS-mediated hepatocyte apoptosis by modulating the PI3K/AKT pathway.

Abstract
BACKGROUND The safety and efficacy of granulocyte colony-stimulating factor (G-CSF) for the treatment of acute-on-chronic liver failure (ACLF) remain uncertain. Therefore, we conducted a meta-analysis to draw a firmer conclusion. METHODS We searched the Cochrane library, PubMed, Embase, and China Biology Medicine disc to identify relevant RCTs performed before January 2020. Risk ratios (RRs) and their 95% confidence intervals (95% CIs) were calculated using a random effects model. MAIN OUTCOME MEASURES RRs (95% CI) for 1-, 2-, and 3-month survival rates. SAMPLE SIZE Six RCTs, including three open-label studies. RESULTS The six studies included 246 subjects (121 in a G-CSF group and 125 in a control group). G-CSF administration significantly improved the 1-, 2-, and 3-month survival rates in patients with ACLF. The pooled RRs (95% CI, P) were 0.43 (0.27-0.69, P=.0004), 0.44 (0.32-0.62, P<.00001), and 0.39 (0.22-0.68, P=.0009), respectively. CONCLUSION G-CSF may be beneficial and effective in the treatment of ACLF, but further studies are needed to verify this conclusion. LIMITATIONS The sample size was small, and studies were restricted to countries in Asia. PROSPERO REGISTRATION NUMBER CRD42021225681 CONFLICT OF INTEREST: None.

Abstract
BACKGROUND The modified creatinine index (mCI), as a surrogate marker of muscle mass, has been associated with poor outcomes in patients undergoing hemodialysis. However, a single assessment may not reflect the clinical significance before an adverse clinical endpoint. OBJECTIVE Analyze mCI trajectories and their association with all-cause mortality in incident hemodialysis patients. DESIGN Retrospective observational cohort. SETTING Outpatient dialysis facility. PATIENTS AND METHODS We followed a cohort of patients who underwent maintenance hemodialysis treatment at least three times weekly for at least three months from 19 June 2010 to 29 December 2017. Clinical and laboratory features were measured at baseline. Longitudinal changes in the mCI were modeled using a joint longitudinal and survival model adjusted for baseline covariates and body mass index trajectories. MAIN OUTCOME MEASURE All-cause mortality. SAMPLE SIZE 408 with 208 males (50.7%). RESULTS The mean (SD) age was 62.2 (12.3) years. The mCI changes were evaluated for a median (interquartile range) follow-up of 2.16 (1.13, 3.73) years. Forty-six percent (n=188) of patients reached the endpoint. A steeper slope (per 0.1 unit increase in the decrease rate) in modified creatinine index was associated with increased risk of all-cause mortality (HR, 1.04; 95% CI, 1.02-1.07; P=.011). In addition, an annual 1 mg/kg/day decrease in modified creatinine index level increased the hazard of all-cause mortality by 4% (HR, 1.04; 95% CI, 1.02-1.07; P=.001). LIMITATIONS Residual kidney function was not observed in the data. Setting was single center and thus results may not be generalizable to other populations. CONCLUSION All-cause death was significantly associated with loss of muscle mass over time. Longitudinal trajectories of nutritional markers may predict the clinical outcomes in patients undergoing hemodialysis. This may also be valuable for individual risk stratification. Furthermore, early management may provide an opportunity to improve patient survival. CONFLICT OF INTEREST None.

Abstract
Acute-on-chronic liver failure (ACLF) is described as a characteristic of acute jaundice and coagulation dysfunction. Effective treatments for ACLF are unavailable and hence are urgently required. We aimed to define the effect of Yi-Qi-Jian-Pi Formula (YQJPF) on liver injury and further examine the molecular mechanisms. In this study, we established CCl4-, LPS-, and d-galactosamine (D-Gal)-induced ACLF rat models in vivo and LPS- and D-Gal-induced hepatocyte injury models in vitro. We found that YQJPF significantly ameliorates liver injury in vivo and in vitro that is associated with the regulation of hepatocyte necroptosis. Specifically, YQJPF decreased expression of receptor-interacting protein kinase 1 (RIPK1), receptor-interacting protein kinase 3 (RIPK3) and pseudokinase mixed lineage kinase domain-like (MLKL) to inhibit the migration of RIPK1 and RIPK3 into necrosome. YQJPF also reduces the expression of inflammatory cytokines IL-6, IL-8, IL-1β, and TNF-α, which were regulated by RIPK3 mediates cell death. RIPK1 depletion was found to enhance the protective effect of YQJPF. Furthermore, we showed that YQJPF significantly downregulates the mitochondrial reactive oxygen species (ROS) production and mitochondrial depolarization, with ROS scavenger, 4-hydroxy-TEMPO treatment recovering impaired RIPK1-mediated necroptosis and reducing the expression of IL-6, IL-8, IL-1β, and TNF-α. In summary, our study revealed the molecular mechanism of protective effect of YQJPF on hepatocyte necroptosis, targeting RIPK1/RIPK3-complex-dependent necroptosis via ROS signaling. Overall, our results provided a novel perspective to indicate the positive role of YQJPF in ACLF.

BACKGROUND Hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) is a severe condition with high mortality due to lack of efficient therapy. Until now, the use of methylprednisolone (MP) in HBV-ACLF is still controversial. We aimed to evaluate the efficacy and safety of MP in HBV-ACLF. METHODS Totally 171 HBV-ACLF patients from three medical centers were randomly allocated into MP group (83 patients treated with MP intravenously guttae for 7 days plus standard treatment: 1.5 mg/kg/day [day 1-3], 1 mg/kg/day [day 4-5], and 0.5 mg/kg/day [day 6-7]) and control group (88 patients treated with standard treatment). The primary endpoints were 6-month mortality and prognostic factors for 6-month survival. The survival time, cause of death, adverse events, liver function, and HBV DNA replication were analyzed. RESULTS The 6-month mortality was significantly lower in MP group than control group [32.4% vs. 42.5%, P = 0.0037]. MP treatment was an independent prognostic factor for 6-month survival [HR (95% CI) 0.547(0.308-0.973); P = 0.040]. Factors associated with reduced 6-month mortality in MP group included HBV DNA and lymphocyte/monocyte ratio (LMR) (P < 0.05). Based on ROC curve, LMR+MELD had a better predictive value for prognosis of HBV-ACLF under MP treatment. No significant difference in HBV DNA replication was observed between groups (P > 0.05). CONCLUSIONS MP therapy is an effective and safe clinical strategy in HBV-ACLF, increasing the 6-month survival rate.

Abstract
Acute-on-chronic liver failure (ACLF) is a severe life-threatening condition with high risk of multiorgan failure, sepsis, and mortality. ACLF activates a multifaceted interplay of both innate and adaptive immune response in the host which governs the overall outcome. Innate immune cells recognize the conserved elements of microbial and viral origin, both to extort instant defense by transforming into diverse modules of effector responses and to generate long-lasting immunity but can also trigger a massive intrahepatic immune inflammatory response. Acute insult results in the activation of innate immune cells which provokes cytokine and chemokine cascade and subsequently initiates aggressive systemic inflammatory response syndrome, hepatic damage, and high mortality in ACLF. Dysregulated innate immune response not only plays a critical role in disease progression but also potentially correlates with clinical disease severity indices including Child-Turcotte-Pugh, a model for end-stage liver disease, and sequential organ failure assessment score. A better understanding of the pathophysiological basis of the disease and precise immune mechanisms associated with liver injury offers a novel approach for the development of new and efficient therapies to treat this severely ill entity. Immunotherapies could be helpful in targeting immune-mediated organ damage which may constrain progression toward liver failure and eventually reduce the requirement for liver transplantation. Here, in this review we discuss the defects of different innate immune cells in ACLF which updates the current knowledge of innate immune response and provide potential targets for new therapeutic interventions.

Abstract
Acute-on-chronic hepatitis B liver failure (ACHBLF) refers to the acute deterioration of liver function during chronic hepatitis B virus infection, and is associated with high mortality, with rapid progression to death. Nucleotide-binding oligomerisation domain-like receptors (NLRs) Family Pyrin Domain Containing 3(NLRP3) inflammasome contributed to the pathogenesis of D-galactosamine and lipopolysaccharide-induced acute liver failure. However, the profile of NLRP3 in patients with ACHBLF has not been demonstrated. This study was therefore conducted to investigate the expression of NLRP3 in patients with ACHBLF and identify the effect of glucocorticoid on NLRP3. We recruited 70 patients with ACHBLF undergoing glucocorticoid treatment for 28 days, 30 patients with chronic hepatitis B (CHB), and 24 healthy controls (HCs) in this study. The relative messenger RNA (mRNA) level of NLRP3 and related genes were measured by reverse transcription polymerase chain reaction, the plasma levels of interleukin-1β (IL-1β) and interleukin-18 (IL-18) were measured by enzyme-linked immunosorbent assay. The mRNA level of NLRP3 was significantly higher in patients with ACHBLF than in patients with CHB as well as HCs (P<0.05). The plasma levels of IL-1β and IL-18 in patients with ACHBLF were significantly higher than in patients with CHB and HCs (P<0.05). The relative mRNA level of NLRP3 in surviving patients decreased significantly compared with that in patients who did not survive after glucocorticoid treatment (P<0.05). In conclusion, NLRP3 increased in patients with ACHBLF. Glucocorticoid could downregulate the expression of NLRP3 in surviving patients with ACHBLF.

Abstract
Acute-on-chronic liver failure is a common pattern of end-stage liver disease in clinical practice and occurs frequently in patients with chronic hepatitis B or HBV-related cirrhosis. New progress in recent years leads to a better understanding of this disease. Areas covered: This review updates the current comprehensive knowledge about HBV-ACLF from epidemiological studies, experimental studies, and clinical studies and provide new insights into the definition, diagnostic criteria, epidemiology, nature history, pathogenesis, treatment and prognostication of HBV-ACLF. Expert commentary: Patients with chronic hepatitis B or HBV-related cirrhosis are at risk of developing acute-on-chronic liver failure, with multi-organ failure and high short-term mortality. The precipitating events can be intra-hepatic or extra-hepatic and the underlying chronic liver injury can be cirrhotic or non-cirrhotic. Host and viral factors contribute to the susceptibility of developing HBV-ACLF. Systemic inflammation is the driver of HBV-ACLF, which can be attributed to non-sterile and sterile factors. Liver transplantation is the definitive treatment for HBV-ACLF. Cell therapy is a promising alternative to LT, but requires validation and still has concern of long-term safety. Other medical therapies, such as nucleoside analogue, artificial liver supporting and glucocorticoid may improve survival in a specific subgroup. New scoring systems improve the accuracy of prognostication in HBV-ACLF, which is critical for early identification of candidates for LT.

Abstract
OBJECTIVE To evaluate the clinical efficacy and safety of Yinchen Zhufu Decoction (, YCZFD) in the treatment of acute-on-chronic liver failure caused by hepatitis B virus (HBV-ACLF) with cold pattern in Chinese medicine (CM). METHODS This is a multi-center randomized controlled trial of integrative treatment of CM and Western medicine (WM) for the management of HBV-ACLF patients. A total of 200 HBV-ACLF patients with cold pattern were equally randomly assigned to receive YCZFD and WM (integrative treatment) or WM conventional therapy alone respectively for 4 weeks. The primary end point was the mortality for HBV-ACLF patients. Secondary outcome measures included Model for End-Stage Liver disease (MELD) score, liver biochemical function, coagulation function and complications. Adverse events during treatment were reported. RESULTS The mortality was decreased 14.28% in the integrative treatment group compared with WM group (χ(2) =6.156, P=0.013). The integrative treatment was found to signifificantly improve the MELD score (t=2.353, P=0.020). There were statistically signifificant differences in aspartate transaminase, total bilirubin, indirect bilirubin, direct bilirubin and prothrombin time between the two groups (P<0.05 or P<0.01). The complications of ascites (χ(2)=9.033, P=0.003) and spontaneous bacteria peritonitis (χ(2)=4.194, P=0.041) were improved signifificantly in the integrative treatment group. No serious adverse event was reported. CONCLUSIONS The integrative treatment of CM and WM was effective and safe for HBV-ACLF patients with cold pattern in CM. The Chinese therapeutic principle "treating cold pattern with hot herbs" remains valuable to the clinical therapy. (Trial registration No. ChiCTR-TRC-10000766).

Abstract
Liver failure (LF) is defined as severe dysfunction in hepatic synthesis, detoxification, and metabolism induced by various etiologies. Clinical presentation of LF typically includes severe jaundice, coagulation disorder, hepatic encephalopathy, and ascites. LF can be classified into acute LF, acute-on-chronic LF (ACLF), and chronic LF. ACLF has been demonstrated as a distinct syndrome with unique clinical presentation and outcomes. The severity, curability, and reversibility of ACLF have attracted considerable attention. Remarkable developments in ACLF-related conception, diagnostic criteria, pathogenesis, and therapy have been achieved. However, this disease, especially its diagnostic criteria, remains controversial. In this paper, we systemically reviewed the current understanding of ACLF from its definition, etiology, pathophysiology, pathology, and clinical presentation to management by thoroughly comparing important findings between east and west countries, as well as those from other regions. We also discussed the controversies, challenges, and needs for future studies to promote the standardization and optimization of the diagnosis and treatment for ACLF.

Abstract
Acute-on-chronic liver failure (ACLF) is a distinct clinical entity and differs from acute liver failure and decompensated cirrhosis in timing, presence of acute precipitant, course of disease and potential for unaided recovery. The definition involves outlining the acute and chronic insults to include a homogenous patient group with liver failure and an expected outcome in a specific timeframe. The pathophysiology of ACLF relates to persistent inflammation, immune dysregulation with initial wide-spread immune activation, a state of systematic inflammatory response syndrome and subsequent sepsis due to immune paresis. The disease severity and outcome can be predicted by both hepatic and extrahepatic organ failure(s). Clinical recovery is expected with the use of nucleoside analogues for hepatitis B, and steroids for severe alcoholic hepatitis and, possibly, severe autoimmune hepatitis. Artificial liver support systems help remove toxins and metabolites and serve as a bridge therapy before liver transplantation. Hepatic regeneration during ongoing liver failure, although challenging, is possible through the use of growth factors. Liver transplantation remains the definitive treatment with a good outcome. Pre-emptive antiviral agents for hepatitis B before chemotherapy to prevent viral reactivation and caution in using potentially hepatotoxic drugs can prevent the development of ACLF.

Abstract
Hepatitis B virus (HBV) associated acute-on-chronic liver failure (ACLF) is an increasingly recognized fatal liver disease encompassing a severe acute exacerbation of liver function in patients with chronic hepatitis B (CHB). Despite the introduction of an artificial liver support system and antiviral therapy, the short-term prognosis of HBV-ACLF is still extremely poor unless emergency liver transplantation is performed. In such a situation, stopping or slowing the progression of CHB to ACLF at an early stage is the most effective way of reducing the morbidity and mortality of HBV-ACLF. It is well-known that the occurrence and progression of HBV-ACLF is associated with many factors, and the outcomes of HBV-ACLF patients can be significantly improved if timely and appropriate interventions are provided. In this review, we highlight recent developments in early warning and clinical outcome prediction in patients with HBV-ACLF and provide an outlook for future research in this field.

Abstract
Over the past 2 decades, the concept of acute-on-chronic liver failure (ACLF) has been proposed as an alternate path in the natural history of decompensated cirrhosis. ACLF thus is characterized by the presence of a precipitating event (identified or unidentified) in subjects with underlying chronic liver disease leading to rapid progression of liver injury and ending in multi-organ dysfunction characterized by high short-term mortality. Multiple organ failure and an increased risk for mortality are key to the diagnosis of ACLF. The prevalence of ACLF ranges from 24% to 40% in hospitalized patients. The pathophysiological basis of ACLF can be explained using the following 4-part model: predisposing event, injury caused by a precipitating event, response to injury, and organ failure. Although several mathematic scores have been proposed for identifying outcomes with ACLF, it is as yet unclear whether these organ failure scores are truly prognostic or only reflective of the dying process. Treatment paradigms continue to evolve but consist of early recognition, supportive intensive care, and consideration of liver transplantation before onset of irreversible multiple organ failure.

Abstract
BACKGROUND Acute-on-chronic liver failure (ACLF) is increasingly recognized as a distinct clinical entity and is associated with a high short-term mortality. The most common cause of ACLF is chronic hepatitis B worldwide. Currently, there is no standardized approach for the management of ACLF and the efficacy and safety of therapeutic modalities are uncertain. DATA SOURCES PubMed and Web of Science were searched for English-language articles. The search criteria focused on clinical trials and observational studies on the treatment of patients with HBV-related ACLF. RESULTS Therapeutic approaches for ACLF in patients with chronic hepatitis B included nucleos(t)ide analogues, artificial liver support systems, immune regulatory therapy, stem cell therapy and liver transplantation. All of these therapeutic approaches have shown the potential to improve liver function and increase patients' survival rate, but most of the studies were not randomized or controlled. CONCLUSION Substantial challenges for the treatment of HBV-related ACLF remain and further basic research and randomized controlled clinical trials are needed.

Abstract
Chronic liver disease, depicted by gradual destruction and fibrosis of the liver, is a condition with high and probably increasing prevalence worldwide. Its deterioration, acute-on-chronic liver failure (ACLF), is characterized by an in-hospital mortality of up to 65%. Infectious complications are the main precipitants eliciting ACLF and concurrently the main cause of death from ACLF. Patients have a marked susceptibility to bacterial infections, which is thought to arise a consequence of an inadequate immune response to microbial challenge, termed immuneparesis. The pathophysiologic mechanisms remain poorly understood. Treatments aimed at restoring the patients' immune function may prevent onset of ACLF and death from secondary infections. A number of drugs approved for patients with liver disease bear immunomodulatory potential such as albumin, glucocorticoids, N-acetylcysteine. Specific targets have been defined that may lead to development of new immunotherapeutic agents. Here, we summarize the pathophysiology of immuneparesis in ACLF and drug candidates to restore immune function and improve survival in the future.

Abstract
BACKGROUND Acute-on-chronic liver failure is a severe, life-threatening entity and the comprehension of this disease is incomplete. Currently, a reasonable surgical model of acute-on-chronic liver failure is still lacking. The aim of this study was to establish a new model of acute-on-chronic liver failure in rats and to investigate the protective effects of methylprednisolone on this model. METHODS An obstructive jaundice model in rats was established. Two weeks later, the animals were subjected to a choledochoduodenostomy and a reduced-size hepatic ischaemia/reperfusion injury. Animals were randomly divided into a control group, a methylprednisolone injected via the tail vein group and a methylprednisolone injected via the portal vein group. The survival rates and serum levels of alanine transaminase, aspartate aminotransferase, total bilirubin, tumour necrosis factor alpha, and interferon gamma of the rats were measured and the pathological changes in liver tissues were observed. RESULTS The survival rate was significantly improved in the methylprednisolone treatment groups. Serum levels of the biochemical indexes were the lowest in the portal vein injection group. Liver tissues under microscopy presented severe pathological injury in the control group. CONCLUSION This model could be useful for further research into acute-on-chronic liver failure and methylprednisolone may be a potential therapeutic agent for this disease.

Abstract
Liver failure is a clinical syndrome of various etiologies, manifesting as jaundice, encephalopathy, coagulopathy and circulatory dysfunction, which result in subsequent multiorgan failure. Clinically, liver failure is classified into four categories: acute, subacute, acute-on-chronic and chronic liver failure. Massive hepatocyte death is considered to be the core event in the development of liver failure, which occurs when the extent of hepatocyte death is beyond the liver regenerative capacity. Direct damage and immune-mediated liver injury are two major factors involved in this process. Increasing evidence has suggested the essential role of immune-mediated liver injury in the pathogenesis of liver failure. Here, we review the evolved concepts concerning the mechanisms of immune-mediated liver injury in liver failure from human and animal studies. Both innate and adaptive immunity, especially the interaction of various immune cells and molecules as well as death receptor signaling system are discussed. In addition, we highlight the concept of "immune coagulation", which has been shown to be related to the disease progression and liver injury exacerbation in HBV related acute-on-chronic liver failure.

World J Gastroenterol 2014; 20:8558-8571. [PMID: 25024610 PMCID: PMC4093705 DOI: 10.3748/wjg.v20.i26.8558] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2013] [Revised: 12/31/2013] [Accepted: 04/09/2014] [Indexed: 02/07/2023] Open
Abstract
AIM: To longitudinally investigate cytokine gene expression and protein levels in Th17 and Treg cells, to observe T-cell phenotypes during hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACHBLF) and to analyze changes in Th17 and Treg phenotypes during disease progression.
METHODS: We measured the expression of seven Th17/Treg differentiation-related genes and serum concentrations of the corresponding cytokines in 18 ACHBLF, 18 chronic hepatitis B (CHB) disease controls and 10 healthy controls (HCs) by real-time quantitative PCR and enzyme linked immunosorbent assay. Peripheral Th17 and Treg cell frequencies were analyzed by flow cytometry.
RESULTS: From the onset of ACHBLF, patients presented with a conductive Th17 differentiation cytokine environment accompanied by high Th17 frequency and high serum IL-17 levels, which were sustained throughout the disease course. The Treg-related cytokine IL-2 and Foxp3 were also up-regulated from disease onset, and Foxp3 gene expression showed a gradually increasing trend during ACHBLF. The circular phenotype of Treg and Th17 cells showed changes from the onset of ACHGLF. At disease onset, Th17 frequency increased significantly compared with both CHB and HCs, but Treg cell frequency decreased significantly compared with CHB. During the ACHBLF event, Th17 frequency remained higher compared with HCs, but decreased sharply from the peak point to the recovery point; Treg cell frequency increased gradually during the ACHBLF event. Treg and Th17 cell counts correlated with ACHBLF development; in all patients, serum IL-17 levels significantly correlated with patient serum ALT levels. In survivors, Th17 frequency at the onset point and the Treg to Th17 ratio at the peak point correlated with the patient’s model for end stage liver disease (MELD) plus sodium (MELD-Na) score. The Treg to Th17 ratio and the Th17 frequency at onset were significant predictors of patient survival. Low Treg/Th17 cell ratios at the onset predicted poor survival. Survivors exhibited an initial decrease in the circulating Treg/Th17 ratio from the onset to the peak time, and subsequently displayed a continuous increase.
CONCLUSION: Treg and Th17 cells showed changes in genes, protein levels and T cell phenotypes during ACHBLF events. An increased Treg/Th17 ratio was associated with the survival of ACHBLF patients.

Abstract
Acute-on-chronic liver failure is a distinct syndrome characterized by a rapid progression of liver disease culminating in organ failure and death. The only definitive treatment is liver transplantation. However, there is a possible element of reversibility and hepatic regeneration if the acute insult can be tided over. Exogenously administered growth factors may stimulate hepatocytes, hepatic progenitor cells and bone marrow-derived cells to supplement hepatic regeneration. The proposed review is intended to provide an in-depth analysis of the individual components of hepatic and bone marrow niches and highlight the growing role of various growth factors in liver regeneration in health and in liver failure.

Prognoses of patients with acute-on-chronic hepatitis B liver failure are closely associated with altered SOCS1 mRNA expression and cytokine production following glucocorticoid treatment. Cell Mol Immunol 2014; 11:396-404.

Abstract
Suppressor of cytokine signaling (SOCS) 1 plays a crucial role in the immune response and might contribute to the prognoses of liver failure treated with glucocorticoid. We recruited 47 acute-on-chronic hepatitis B liver failure (ACHBLF) patients receiving glucocorticoid treatment and 30 healthy controls to determine the potential effects of glucocorticoid on the transcriptional level of SOCS1 in peripheral blood mononuclear cells. On the third and twenty-eighth days of glucocorticoid treatment, SOCS1 expression was negatively correlated with model for end-stage liver disease (MELD) score. Interleukin-6 (IL-6) and tumor-necrosis factor-α (TNF-α) levels were statistically lower, while the SOCS1 transcription level was higher in survivors than non-survivors both in pre- and post-treatment ACHBLF patients. The methylation rate of the SOCS1 promoter in ACHBLF patients was higher than in healthy control patients as determined by methylation-specific polymerase chain reaction. The mRNA level of SOCS1 in methylated promoters was significantly lower than from patients with unmethylated SOCS1 promoters. interferon (IFN)-γ-responsive and STAT1-dependent gene expression was higher in survivors and was dramatically decreased with rising expression of SOCS1 after glucocorticoid treatment. Mortality rates were significantly higher in methylated patients than for those without methylation at the end of a 90-day follow-up. Furthermore, we found that five in six surviving patients displayed demethylated SOCS1 on the twenty-eighth day after treatment, while that number was 3 in 10 in the non-survivors. These findings suggested that ACHBLF patients without SOCS1 methylation may have a favorable response to corticosteroid treatment.

Abstract
BACKGROUND & AIMS Acute-on-chronic liver failure (ACLF) is a serious hepatic ailment with impaired immunity and poor treatment options resulting high mortality. Treatment with granulocyte colony-stimulating factor(G-CSF) mobilizes CD34(+) cells in ACLF patients; however its effect on impaired immune responses remains to be elucidated. To analyse the effect of G-CSF in immune modulation in ACLF. METHODS We have analysed the frequencies of circulating and intrahepatic myeloid (mDCs) and plasmacytoid(pDCs) dendritic cells (DCs) and T cells in ACLF patients treated with G-CSF (Group A; n = 23) and placebo (Group B; n = 24) using flow cytometry. IFN-c production was compared in both groups following stimulation of PBMCs with phorbol myristate acetate (PMA). RESULTS In Group A, circulating and intrahepatic mDCs, pDCs (P < 0.04, P < 0.02) and T cells(CD3, CD4 and CD8) increased significantly post-G-CSF treatment in comparison to placebo group. Importantly in Group A, IFN-c-producing CD8 T cells were significantly decreased (P > 0.05) along with decreased serum bilirubin and international normalized ratio (INR). Intrahepatic DCs and IFN-clevel were compared in survivor and non-survivor. Non-survivors from both groups, showed decreased DCs, high IFN-c level and no improvement in clinical parameters including s-bilirubin and INR. CONCLUSIONS G-CSF therapy increased the frequencies of dendritic cells and reduced IFN-c secreting CD8 T cells with improved clinical severity indices. Decreased IFN- c production may contribute to reduced hepatocellular damage in ACLF patients.Our observations support the basis for further use of G-CSF therapy as immune modulator in these patients.

Abstract
BACKGROUND AND AIM Acute-on-chronic liver failure (ACLF) caused by hepatitis B virus (HBV) is a severe disease with high mortality. Immune injury plays an important role during the early stage of the disease. Our research aimed to investigate the safety and efficacy of dexamethasone therapy for patients with HBV-related ACLF. METHODS A total of 134 inpatients with HBV-induced ACLF were enrolled from January 2009 to December 2012. All the patients received the standard medicine treatment (SMT), among whom 31 cases underwent additional dexamethasone injection for three times (dexamethasone treatment [DMT] Group). A total of 35 patients (SMT Group) matched for baseline characters served as controls. Both the groups were followed up for 12 weeks. The survival rates, liver functions, and complications were recorded. RESULTS The 12-week cumulative survival rates were 45.7% (16/35)and 48.4% (15/31) for SMT Group and DMT Group, respectively, and no significant differences were found (P = 0.959). There were no dramatic differences in liver function and model for end-stage liver disease (MELD) score at 1, 2, 4, 8, and 12 weeks between two groups. There were no significant differences in the incidence of complications (i.e. infection, gastrointestinal bleeding, encephalopathy, hepatorenal syndrome, and ascites) from 1 to 12 weeks between Group SMT and Group DMT. More than 40 ages, MELD score more than 28 and encephalopathy were independent risk factors for the mortality of patients. CONCLUSIONS Dexamethasone cannot improve liver functions and 12-week survival rates of patients with HBV-related ACLF. Age, MELD score, and encephalopathy are independent risk factors.
