Abstract
Viral hepatitis-induced acute liver failure (ALF) is a preventable cause for liver-related mortality worldwide. Viruses are the most common cause for ALF in developing nations in contrast to the west, where acetaminophen is largely responsible. Viruses may be hepatotropic or affect the liver secondary to a systemic infection. In tropical countries, infections such as leptospirosis, scrub typhus and malaria can mimic the symptoms of ALF. Differentiating these ALF mimics is crucial because they require etiology-specific therapy. Treatment of viral hepatitis-induced ALF is two-pronged and directed towards providing supportive care to prevent organ failures and antiviral drugs for some viruses. Liver transplantation (LT) is an effective modality for patients deteriorating despite adequate supportive care. Early referral and correct identification of patients who require a transplant are important. Liver support devices and plasma exchange have evolved into "bridging modalities" for LT. Preventive strategies such as hand hygiene, use of clean and potable water and inclusion of vaccines against viral hepatitis in the national program are simple yet very effective methods focusing on the preventive aspect of this disease.

Issues of intensive care and liver transplantation tactics in fulminant liver failure. BULLETIN OF THE MEDICAL INSTITUTE "REAVIZ" (REHABILITATION, DOCTOR AND HEALTH) 2023. [DOI: 10.20340/vmi-rvz.2023.1.tx.2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 03/17/2023]
Abstract
Fulminant liver failure is usually characterized as severe acute liver injury with encephalopathy and synthetic dysfunction (international normalized ratio [INR] ≥1.5) in a patient without cirrhosis or previous liver disease. Management of patients with acute liver failure includes ensuring that the patient is cared for appropriately, monitoring for worsening liver failure, managing complications, and providing nutritional support. Patients with acute liver failure should be treated at a liver transplant center whenever possible. Serial laboratory tests are used to monitor the course of a patient's liver failure and to monitor for complications. It is necessary to monitor the level of aminotransferases and bilirubin in serum daily. More frequent monitoring (three to four times a day) of blood coagulation parameters, complete blood count, metabolic panels, and arterial blood gases should be performed. For some causes of acute liver failure, such as acetaminophen intoxication, treatment directed at the underlying cause may prevent the need for liver transplantation and reduce mortality. Lactulose has not been shown to improve overall outcomes, and it can lead to intestinal distention, which can lead to technical difficulties during liver transplantation. Early in acute liver failure, signs and symptoms of cerebral edema may be absent or difficult to detect. Complications of cerebral edema include increased intracranial pressure and herniation of the brain stem. General measures to prevent increased intracranial pressure include minimizing stimulation, maintaining an appropriate fluid balance, and elevating the head of the patient's bed. For patients at high risk of developing cerebral edema, we also offer hypertonic saline prophylaxis (3%) with a target serum sodium level of 145 to 155 mEq/L (level 2C). High-risk patients include patients with grade IV encephalopathy, high ammonia levels (>150 µmol/L), or acute renal failure, and patients requiring vasopressor support. Approximately 40 % of patients with acute liver failure recover spontaneously with supportive care. Predictive models have been developed to help identify patients who are unlikely to recover spontaneously, as the decision to undergo liver transplant depends in part on the likelihood of spontaneous recovery of the liver. However, among those who receive a transplant, the one-year survival rate exceeds 80 %, making this treatment the treatment of choice in this difficult patient population.

Abstract
The global burden of deaths caused by liver failure is substantial. The Asia-Pacific region is home to more than half of the global population and accounted for 62.6% of global deaths because of liver diseases in 2015. The aetiology of liver failure varies in different countries at different times. Viruses (Hepatitis A, B and E), drugs (herbs and anti-tuberculous drugs), toxins (alcohol use) and autoimmune flares are mainly responsible of majority of liver failure in individuals with normal liver (acute liver failure; ALF); else these may precipitate liver failure in those with chronic liver disease (acute-on-chronic liver failure; ACLF). Concomitant increases in alcohol misuse and metabolic syndrome in recent years are concerning. Ongoing efforts to address liver failure-related morbidity and mortality require accurate contemporary estimates of epidemiology and outcomes. In light of the ever-changing nature of liver disease epidemiology, accurate estimates for the burden of liver failure across the countries are vital for setting clinical, research and policy priorities. In this review, we aimed to describe the current as well as changing epidemiological trends of common liver failure syndromes, ALF and ACLF in the Asia-Pacific region.

Pediatric acute liver failure: An experience of a pediatric intensive care unit from resource limited settings. Front Pediatr 2022; 10:956699.

Abstract
INTRODUCTION Pediatric acute liver failure is a rare and serious disease. Though liver transplantation is considered as the established treatment option for patients who are unlikely to recover with medical management, however, with the advancement of medical care there has been an increase in spontaneous regeneration of liver, obviating the need for liver transplantation. We identified the etiologies, outcome and prognostic factors of acute liver failure and the validity of the existing liver transplantation criteria to predict the outcome of pediatric acute liver failure. MATERIALS AND METHODS This was a retrospective study done from January 2014 to December 2019 in a tertiary pediatric critical care unit in South India. All children aged between 1 month to 18 years admitted with acute liver failure were enrolled. RESULTS Of 125 children with acute liver failure, the main etiologies were infections (32%), indeterminate (23%), paracetamol toxicity (21%), metabolic (13%) and others (11%). Dengue was the most common infection (55%). The median pediatric logistic organ dysfunction score at admission was 12 (4-27). Of 125 patients, 63.2% (n = 79) had spontaneous regeneration which was higher in paracetamol induced (92.3%) compared to non-paracetamol induced acute liver failure (55.5%). Only two patients underwent liver transplantation and 35% died. Peak alanine transaminase and use of inotropes significantly predicted the outcome of disease. Of 38 children meeting King's College Hospital criteria for liver transplantation, 57.9% had spontaneous regeneration and 36.8% died. Of 74 children meeting INR > 4 criteria, 54% (n = 40) had spontaneous regeneration and 43.2% died. INR >4 criteria was more sensitive than King's College Hospital criteria for predicting the need for liver transplantation. CONCLUSION Pediatric acute liver failure is caused by varied etiologies and infections were the commonest cause. Despite having a seriously ill cohort of patients, medical management resulted in spontaneous regeneration in the majority of children with acute liver failure. The use of inotropes, advanced hepatic encephalopathy, and peak alanine transaminase were predictors of poor outcome in children with acute liver failure and these patients could be considered for liver transplantation as available. Therefore, we may need to develop better predictors of pediatric acute liver failure in resource limited settings.

Abstract
BACKGROUND/AIM We aimed to elucidate the hemodynamic alterations in the liver of patients with acute hepatitis (AH) using computed tomography perfusion imaging. PATIENTS AND METHODS For 14 patients with AH and nine patients with no disease (ND group), we compared the mean arterial blood flow (AF), portal blood flow (PF) and perfusion index (%) [PI=AF/(AF+PF) ×100] of the right and left liver lobes and investigated their relationship with clinical factors. RESULTS The mean PI of the right lobe in the AH group (30.5±10.0%) was significantly higher than that in the ND group (20.8±9.7%) (p=0.031). For all patients of the AH and ND groups, the PI of the right lobe was increased as the prothrombin time decreased (R=-0.56, p=0.006) and as the prothrombin time-international normalized ratio increased (R=0.48, p=0.02). CONCLUSION The PI of the right liver lobe may increase in AH and may be a predictive parameter for the severity of hepatic failure.

Abstract
Acute liver failure (ALF) is not an uncommon complication of a common disease such as acute hepatitis. Viral hepatitis followed by antituberculosis drug-induced hepatotoxicity are the commonest causes of ALF in India. Clinically, such patients present with appearance of jaundice, encephalopathy, and coagulopathy. Hepatic encephalopathy (HE) and cerebral edema are central and most important clinical event in the course of ALF, followed by superadded infections, and determine the outcome in these patients. The pathogenesis of encephalopathy and cerebral edema in ALF is unique and multifactorial. Ammonia plays a crucial role in the pathogenesis, and several therapies aim to correct this abnormality. The role of newer ammonia-lowering agents is still evolving. These patients are best managed at a tertiary care hospital with facility for liver transplantation (LT). Aggressive intensive medical management has been documented to salvage a substantial proportion of patients. In those with poor prognostic factors, LT is the only effective therapy that has been shown to improve survival. However, recognizing suitable patients with poor prognosis has remained a challenge. Close monitoring, early identification and treatment of complications, and couseling for transplant form the first-line approach to manage such patients. Recent research shows that use of dynamic prognostic models is better for selecting patients undergoing liver transplantation and timely transplant can save life of patients with ALF with poor prognostic factors.

Abstract
Acute liver failure (ALF) is an infrequent, unpredictable, potentially fatal complication of acute liver injury (ALI) consequent to varied etiologies. Etiologies of ALF as reported in the literature have regional differences, which affects the clinical presentation and natural course. In this part of the consensus article designed to reflect the clinical practices in India, disease burden, epidemiology, clinical presentation, monitoring, and prognostication have been discussed. In India, viral hepatitis is the most frequent cause of ALF, with drug-induced hepatitis due to antituberculosis drugs being the second most frequent cause. The clinical presentation of ALF is characterized by jaundice, coagulopathy, and encephalopathy. It is important to differentiate ALF from other causes of liver failure, including acute on chronic liver failure, subacute liver failure, as well as certain tropical infections which can mimic this presentation. The disease often has a fulminant clinical course with high short-term mortality. Death is usually attributable to cerebral complications, infections, and resultant multiorgan failure. Timely liver transplantation (LT) can change the outcome, and hence, it is vital to provide intensive care to patients until LT can be arranged. It is equally important to assess prognosis to select patients who are suitable for LT. Several prognostic scores have been proposed, and their comparisons show that indigenously developed dynamic scores have an edge over scores described from the Western world. Management of ALF will be described in part 2 of this document.

Abstract
Acute liver failure is divided into hyperacute, acute and subacute liver failure. Ascites is a common complication of subacute liver failure. Although animal models of acute liver failure have been established, the study of the pathogenesis of subacute liver failure with ascites complication is hampered by the lack of experimental animal model. The present study aimed at providing a mouse model of subacute liver failure with ascites complication. Kunming mice were intraperitoneally injected with (-)-epigallocatechin-3-gallate (EGCG), a redox-active polyphenol from green tea, for 32 consecutive days with step-wise increased dosage. The EGCG treatment resulted in liver failure as evidenced by extensive hepatocyte necrosis observed histologically along with significant elevation of serum alanine aminotransferase, aspartate aminotransferase, total bilirubin and direct bilirubin levels as well as significant reduction of serum albumin. Liver fibrosis was not observed by Masson staining and fibrosis-associated proteins were not increased. The mortality was less than 12% and the survival mice developed noticeable ascites. Hepatic thioredoxin and glutathione systems were activated by the EGCG. These adaptive responses might render most mice tolerable to the EGCG treatment. The EGCG treatment significantly up-regulated renal urea transporter A1 and promoted its trafficking to apical membrane. These alterations, known to increase water reabsorption, may be responsible, at least in part, for the formation of the ascites. Overall, the mice treated with gradually elevated doses of EGCG exhibits some of the features observed in patients with subacute liver failure, especially ascites. This mouse model is a useful tool for investigating the pathogenesis of subacute liver failure with ascites complication.

Abstract
Background and aims Acute liver failure (ALF) is a rare disease entity with a high mortality. Management is dependent on accurate prognostication. Materials and methods One hundred consecutive patients presenting with ALF were prospectively evaluated. The King's college criteria (KCC), ALF early dynamic model (ALFED), sequential organ failure assessment (SOFA) score, and acute physiology and health evaluation II (APACHE II) scores were compared to predict mortality. Results There were significant differences in means of all the scores between survivors and nonsurvivors. The SOFA 48 hours had the highest area under receiver operating characteristic curve (AUC) (0.857) closely followed by the ALFED score (0.844). The optimal cutoff for the SOFA score at 48 hours to predict subsequent survival outcome is ≥10 and for the ALFED score is ≥5. Sequential organ failure assessment 48 hours had a good sensitivity of 87%, and the ALFED score showed a good specificity of 84%. The decision curve analysis showed that between a threshold probability of 0.13 and 0.6, use of the SOFA score provided the maximum net benefit and at threshold probabilities of >0.6, the use of ALFED score provided the maximum clinical benefit. Conclusion Dynamic scoring results in better prognostication in ALF. The SOFA 48 hours and ALFED score have good prognostication value in nonacetaminophen-induced liver failure.

Abstract
BACKGROUND AND AIMS 1~4% of acute hepatitis B (AHB) cases in adults progresses to acute liver failure (ALF).The predictors of ALF and prognosis for patients with ALF are not clear. This study investigated some of predictive and prognostic factors for AHB progression to ALF. METHODS A retrospective analysis was used to assess the clinical and laboratory features of 293 patients diagnosed with AHB; the patients were divided into the following two groups: ALF (n = 13) and non-ALF (n = 280). RESULTS In total,13 of the 293 (4.43%) patients developed ALF (10 recovered、3 died). The variables of age, anti-HBc IgM titers≥10 S/CO, HBeAg negativity, and total bilirubin (TB) at admission were significantly higher in ALF patients than in non-ALF patients. Compared to non-ALF patients, ALF patients had significantly lower values for prothrombin time activity (PTA), serum albumin, and HBV DNA. At discharge, ALF patients had lower TB normalization rates and much faster clearance of HBsAg, HBeAg and HBVDNA than non-ALF patients. In multivariate analysis, TB≥5×upper limit of normal (ULN) and HBeAg negative status were independent predictors for ALF development at admission, with 84.6% sensitivity, 85.7% specificity, a likelihood ratio of 5.91 and an area under the receiver operating characteristics curve (AUROC) of 0.850.Those who died had lower levels of peak PTA (<20%) and higher levels of peak hepatic encephalopathy (HE) grade (III-IV) than those who recovered. CONCLUSIONS Of the patients with ALF, 23.1% died. TB≥5×ULN and HBeAg negative status were the most effective and practicable factors distinguishing ALF from AHB at admission before the onset of encephalopathy. Peak PTA<20% and/or HE grade III-IV were independent predictors of a high probability of death or a need for transplantation.

Abstract
There is a strong imperative to develop valid and accurate prognostic modeling for acute liver failure (ALF). Despite the numerous clinical models that have been proposed thus far and the use of some such models, that is, King's College Criteria and Model for End-Stage Liver Disease, in clinical practice to aid decision-making, there is a significant need for improvement for determining patients' clinical course, survival, and requirement for liver transplantation. Future prognostic models shall need a stronger statistical foundation and accountability for time and variability in the clinical course of ALF and be applied for pretransplant and posttransplant outcomes.

Abstract
BACKGROUND A significant proportion of cases of acute liver failure (ALF) do not have an identifiable cause; so called "non A-E," "non A, non B, non C," "seronegative" or "indeterminate" hepatitis. However, this entity is clinically not well described. AIM To collate the known incidence and outcomes in indeterminate hepatitis. This systematic review sought to identify potential aetiologies that ought to be considered, and identify likely future objectives in classification and treatment strategies for indeterminate hepatitis. METHODS Literature review to determine aetiological factors, prevalence and outcomes relating to indeterminate hepatitis. RESULTS There is significant heterogeneity within the reported cases of indeterminate hepatitis in the literature. Some of the potential infective aetiologies which are reviewed here include: parvovirus B19 (PVB19), herpes simplex virus (HSV), Toga-Like Virus and the Annelloviridae (including SEN-V). Interestingly, this condition predominately affects middle aged women, with subacute progression of the liver failure. In addition, the prognosis of indeterminate hepatitis is poor, with reduced spontaneous survival compared with other causes of acute liver failure and increased need for emergency liver transplantation. CONCLUSIONS Whilst various pathological processes have been implicated in the development of indeterminate hepatitis, the specific cause remains elusive. There is an urgent need for general consensus on a specific definition and exclusion of confounding aetiologies with coordinated multicentre investigation of this rare condition to identify aetiology and develop therapies to reduce the significant mortality and need for emergency liver transplantation associated with this condition.

Abstract
Objective: The objective of the study is to compare the model for end-stage liver disease (MELD) with clinical prognostic indicators (CPI) specifically the change in these parameters after 48 h of admission in predicting the mortality in patients with acute liver failure (ALF) due to acute viral hepatitis. Materials and Methods: An open label, investigator-initiated prospective study was conducted that included 41 patients with acute viral hepatitis with ALF. The cases were followed prospectively till death or discharge. The MELD and CPI were calculated at admission and 48 h of admission. Results: Patients having no change or worsening in CPI score, i.e., delta CPI more negative had a higher mortality over the next 48 h compared to patients having an improvement in their respective CPI score. Delta CPI predicted adverse outcome better than the presence of any three CPI on admission (P = 0.019). Patients having no change or a worsening in MELD score, i.e., delta MELD more negative, had a higher mortality in the next 48 h compared to the patients having improvement in their respective MELD score. However, MELD >33 on admission was superior to delta MELD in predicting the adverse outcome (P = 0.019). Conclusion: Among the patients with ALF due to viral hepatitis, delta CPI was found to be superior to delta MELD in predicting the adverse outcome in patients with viral ALF (P < 0.0001).

Abstract
Background Acute liver failure (ALF) is a critical illness with a large number of viral and nonviral causes. Clinical course and etiologies in the Asian countries are different from those reported from the Western world and mortality is high. There may even be intracountry variations in large countries like India, which have differing culture, ethnicity, and environment. Data from North-east part of India is lacking. Materials and methods Acute liver failure cases (>14 years of age) seen over a period of 8 years (n = 255) were studied at a Government Medical College in Assam for their etiological and other demographic profile. Viral serology was carried out and revalidated at a laboratory in New Delhi. Results Majority of cases were <30 years of age. Commonest etiology was nonviral (non-ABCE). Amongst viral causes, hepatitis A and E were common, while hepatitis B virus (HBV) was rare. Unknown herbal medication use was very frequent in our cases with a significantly higher mortality. Mortality was highest in cases in 3rd decade of life. Statistically, international normalized ratio (INR) was the strongest predictor of death. Conclusion Unlike the rest of India, hepatitis virus is not the major cause of ALF in our part; hepatitis A being commoner than hepatitis E, and B is rare. Unknown herbal medications are major cause of mortality and is important medicosocial issue. Our study highlights the differences in the profile of ALF from other Indian and western studies, possibly due to sociocultural factors prevalent in this part.

Xie GJ, Zhang HY, Chen Q, Liu HM, You JP, Yang S, Mao Q, Zhang XQ. Changing etiologies and outcome of liver failure in Southwest China. Virol J 2016; 13:89. [PMID: 27260248 PMCID: PMC4893219 DOI: 10.1186/s12985-016-0536-0] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2015] [Accepted: 05/09/2016] [Indexed: 12/30/2022] Open
Abstract
Background The prognosis of liver failure depends greatly on the underlying cause, and there were few data about the prognosis, etiologies or trigger factors of liver failure in China based on long-term and large samples cohorts. Methods We screened out 3171 liver failure cases from 25467 patients hospitalized in our department between 2000 and 2012 according to Chinese criteria, and determined their etiologies and prognosis. Results 97.3 % cases were associated with at least one of 25 identified factors. The 3 leading etiologies were HBV (91.6 %), alcohol (18.1 %) and antiviral therapy (AVT) related hepatitis B flares (6.7 %). Acute-on-chronic liver failure (ACLF) accounted for 92.1 % of all cases. 96.5 % ACLF cases were associated with HBV, in which the percentage of AVT related flares increased from 0 % in 2000 up to 11.5 % in 2012, and hepatitis virus superinfection declined from peak 19.3 % in 2002 down to 2.5 % in 2012. Three-month spontaneous survival (SS) rate of 3171 cases was 31.4 %, but improved from 17.4 % in 2000 up to 40.4 % in 2012. SS was significantly different among various etiological groups (P = 0.000). In HBV related liver failure aged 25 to 54 years, males accounted for 87.6 %, and had a progressively decreased SS with increasing age. From 25 to 54 years, SS was lower in male than in female HBV related liver failure, and having significant difference in cases of ages 40 to 44 years (27.6 % versus 50.9 %, P = 0.001). Conclusion Etiologies of liver failure were numerous and varied in southwest China. HBV was the most leading cause of liver failure, especially in ACLF. AVT related flares had become the third leading cause of ACLF. The prognosis of liver failure remained poor, but had markedly improved in recently 3 years. Middle-aged male HBsAg carriers had an extremely higher risk for liver failure and worse prognosis compared to female.Etiologies of liver failure were numerous and varied in southwest China. HBV infection is the main cause of liver failure in southwest China, especially the major cause of ACLF. Antiviral related liver failure, especially the NUCs withdrawal induced ACLF were extremely increased, which has replaced the superinfection as the third important cause of HBV-ACLF. The prognosis of liver failure is still poor, but the spontaneous survival rate showed a trend of steady rise in recent years. The prognosis of patients with liver failure caused by different causes also exists certain difference, the more damage factors bulls the worse prognosis. The prognosis of the HBV and HCV reactivation induced by the steroids was poor.Interferon treatment of CHB in ACLF although rare, but should be taken into consideration seriously. Patients with liver failure caused by different etiologies showed larger differences of gender and age distribution. Gender and age are the important factors with the occurrence and prognosis of HBV-ACLF.

Abstract
INTRODUCTION Acute kidney injury is associated with a poor prognosis in acute liver failure but little is known of outcomes in patients undergoing transplantation for acute liver failure who require renal replacement therapy. METHODS A retrospective analysis of the United Kingdom Transplant Registry was performed (1 January 2001-31 December 2011) with patient and graft survival determined using Kaplan-Meier methods. Cox proportional hazards models were used together with propensity-score based full matching on renal replacement therapy use. RESULTS Three-year patient and graft survival for patients receiving renal replacement therapy were 77.7% and 72.6% compared with 85.1% and 79.4% for those not requiring renal replacement therapy (P<0.001 and P = 0.009 respectively, n = 725). In a Cox proportional hazards model, renal replacement therapy was a predictor of both patient death (hazard ratio (HR) 1.59, 95% CI 1.01-2.50, P = 0.044) but not graft loss (HR 1.39, 95% CI 0.92-2.10, P = 0.114). In groups fully matched on baseline covariates, those not receiving renal replacement therapy with a serum creatinine greater than 175 μmol/L had a significantly worse risk of graft failure than those receiving renal replacement therapy. CONCLUSION In patients being transplanted for acute liver failure, use of renal replacement therapy is a strong predictor of patient death and graft loss. Those not receiving renal replacement therapy with an elevated serum creatinine may be at greater risk of early graft failure than those receiving renal replacement therapy. A low threshold for instituting renal replacement therapy may therefore be beneficial.

Abstract
This prospective study was designed to evaluate whether early changes in actin-free Gc-globulin levels were associated with complications and outcomes and to identify factors associated with persistent low actin-free Gc-globulin levels in acute liver failure (ALF). Thirty-two consecutive ALF patients admitted from October 2011 to December 2012 were followed up until death or complete recovery. All had serum actin-free Gc-globulin estimation at admission and at day three or expiry. Logistic regression analysis was performed to identify independent predictors of mortality. A receiver operating characteristic curve analysis was also performed. Nonsurvivors had significantly lower median actin-free Gc-globulin levels than survivors (87.32 vs 180 mg/L; P < 0.001). A receiver operating characteristic curve analysis revealed an area under curve (AUC) of 0.771 and showed that serum actin-free Gc-globulin level of ≤124 mg/L would predict mortality with 92% sensitivity and 71.4% specificity. Patients with lower serum actin-free Gc-globulin levels and decreasing trend in serum actin-free Gc-globulin levels were found to have more mortality and developed more complications. Logistic regression analysis showed that serum actin-free Gc-globulin, total leucocyte count and serum creatinine at admission were independent predictors of mortality. Incorporating these variables, a score predicting mortality risk at admission was derived. The scoring system was compared to MELD score and King's College Criteria as individual predictor of mortality. Serum actin-free Gc-globulin level at presentation is predictive of outcome and can be used for risk stratification. Its persistent low-level predicts mortality and is correlated with various complications.

Abstract
OBJECTIVES The Model for End-Stage Liver Disease score and King's College Hospital (KCH) criteria are accepted prognostic models acute liver failure (ALF), while the use of (APACHE) scores predict to outcomes of emergency liver transplantation is rare. MATERIALS AND METHODS The present study included 87 patients with ALF who underwent liver transplantation. We calculated (KCH) criteria, as well as MELD, APACHE II, and APACHE III scores at the listing date for comparison with 3-month outcomes. RESULTS According to the Youden-Index, the best cut-off value for the APACHE II score was 8.5 with 100% sensitivity, 49% specificity, 24% positive predictive value (PPV), and 100% negative predictive value (NPV). Patients with <8.5 points had a significantly higher survival rate (P < .05). The proposed APACHE III cut-off was 80. The APACHE III score demonstrated the highest specificity and PPV (90% specificity, 50% PPV). The NPV was 92%. With a 90-point threshold the specificity increased to 98% with 75% PPV and 89% NPV. Only 1 of 4 patients with a score >90 survived transplantation (P = .001). MELD score and KCH criteria were not significant (P > .05). According to the Hosmer-Lemeshow test, only the APACHE III score adequately describe the data. CONCLUSIONS The APACHE III score was superior to KCH criteria, MELD score, and APACHE II score to predict outcomes after transplantation for ALF. It is a valuable parameter for pretransplantation patient selection.

Abstract
Untreated acute liver failure (ALF) has a poor outcome and so rapid diagnosis and management is vital if the patient is to survive. ALF has such profound and widespread physiological consequences that whenever possible, patients with ALF should be managed in an intensive care unit. Management is to support the physiology and treat the underlying cause. Advice should be sought from a centre capable of performing liver transplantation. Should recovery seem unlikely, liver transplantation is a viable treatment option in some cases.

Abstract
Hepatitis E virus is a positive strand RNA virus with three open reading frames which is transmitted predominantly through the fecal contamination of water and food. It is the most common cause of acute liver failure in endemic areas. Pregnant women especially from the Indian subcontinent and Africa are at increased risk of contracting acute HEV infection as well as developing severe complications including ALF. Transmission of HEV occurs from mother to unborn child. Both maternal and fetal complications may occur, including abortion, fetal demise, preterm labor and maternal or neonatal death. The precise reasons for increased susceptibility to HEV infection during pregnancy and associated severe disease are still an enigma. Management is supportive and termination of pregnancy is not recommended as a general rule. Prevention of infection is of vital importance, as availability of clean drinking water can reduce the burden of this disease in the community. There is a need for future research to focus on prevention of ALF in pregnancy and to study the disease pathogenesis, which is not explicitly understood at present. The availability of a vaccine may alter the natural course of the disease in this select population which is at risk.

Abstract
AIM To study the factors associated with outcome in acute liver failure (ALF) in an intensive care unit (ICU). METHODS Consecutive patients with ALF admitted to the ICU from August 2003 to April 2010 were included. Factors associated with the primary outcome, death or survival, were compared. RESULTS Of 52 patients of median age 19 years (range 3-65), 35 (67 %) died. The etiology was viral hepatitis in 66 %, drug induced (anti-tubercular therapy) in 15 % and idiopathic in 15 %. Grades III+IV encephalopathy were found in 12 (70.6 %) survivors as against 33 (94.3 %) nonsurvivors (p = 0.019). The median admission sequential organ failure assessment (SOFA) score was eight in survivors vs. 12 in nonsurvivors (p < 0.001). Median admission prothrombin time (PT) was 42 s in survivors vs. 51 in nonsurvivors (p = 0.384); 16/17 (94.1 %) survivors had normal PT on day 4 as compared to 7/35 (20 %) nonsurvivors (p < 0.001). Median PT on day 4 was 18 s in survivors against 37 in nonsurvivors (p < 0.001). Serum bilirubin, alanine aminotransferase; and serum creatinine, sodium and phosphorus were similar in survivors and nonsurvivors. Mechanical ventilation, vasopressors and dialysis were used in 65 %, 30 %, and 12 % survivors as against 100 % (p < 0.001), 51 % and 26 % nonsurvivors. Sixteen patients had upper gastrointestinal (GI) bleed. Blood cultures were positive more often in nonsurvivors (p = 0.058). On multiple regression analysis, factors independently associated with outcome included admission SOFA score >9.5 and absolute value of PT on day 4. CONCLUSIONS Grades III and IV encephalopathy, higher SOFA score at admission and a prolonged PT which did not normalize by 4 days were associated with mortality in ALF.

Abstract
OBJECTIVES We sought to determine whether markers of T-cell immune activation, including soluble interleukin 2 receptor alpha (sIL2Rα) levels predict outcome in pediatric acute liver failure and may target potential candidates for immunomodulatory therapy. METHODS We analyzed markers of immune activation in 77 patients with pediatric acute liver failure enrolled in a multinational, multicenter study. The outcomes were survival with native liver, liver transplantation (LT), and death without transplantation within 21 days after enrollment. RESULTS Adjusting for multiple comparisons, only normalized serum sIL2Rα level differed significantly among the 3 outcomes, and was significantly higher in patients who died (P=0.02) or underwent LT (P=0.01) compared with those who survived with their native liver. The 37 patients with normal sIL2Rα levels all lived, 30 with their native liver. Of the 15 subjects with markedly high sIL2Rα (≥5000 IU/mL), 5 survived with their native liver, 2 died, and 8 underwent LT. CONCLUSIONS Evidence of immune activation is present in some patients who die or undergo LT. Patients with higher sIL2Rα levels were more likely to die or undergo LT within 21 days than those with lower levels. Identifying a subset of patients at risk for poor outcome may form the foundation for targeted clinical trials with immunomodulatory drugs.

Abstract
PURPOSE To investigate the etiological characteristics of patients with liver failure in the past 10 years. METHODS Clinical and investigational data in hospitalized patients with liver failure admitted from 2002 to 2011 were retrospectively analyzed. Standard definitions and criteria were used to assess disease etiology. RESULTS Of these 3,916 patients, 3,429 (87.6 %) had acute-on-chronic liver failure (ACLF), 114 (2.9 %) acute liver failure (ALF), and 373 (9.5 %) subacute liver failure. Viral infection was the most common cause of liver failure in the 3,295 patients (84.1 %). Hepatitis of unknown etiology was deemed responsible for 371 cases of liver failure (9.5 %). Drug-induced liver injury, alcoholic hepatitis, and autoimmune hepatitis led to 120 cases (3.1 %), 109 cases (2.8 %), and 19 cases (0.5 %), respectively. The most common cause of ACLF was HBV infection (87.3 %), while the main causes of acute and subacute liver failure were hepatitis of unknown etiology (39.4 %), viral infection (36.6 %), and drug-induced liver injury (19.3 %). Our data showed that the incidence of liver failure caused by HBV gradually decreased from 86.5 % in 2002 to 69.2 % in 2011. However, the incidence of hepatitis of unknown etiology, drug-induced liver injury, and alcoholic hepatitis was increased. CONCLUSIONS HBV infection is the main cause of liver failure in China. However, the incidence of HBV-related liver failure has gradually decreased in the past 10 years. Hepatitis of unknown etiology has replaced HBV infection as the most common apparent cause of acute liver failure.

Abstract
Acute liver failure (ALF) is a life-threatening condition characterized by jaundice, encephalopathy and coagulopathy leading to multiorgan failure in a patient with no prior history of liver disease. Forty three consecutive patients of ALF admitted in Pediatric ICU were studied for etiology and prognostic factors. Etiology was established in 91% cases. Viral infections were the most common cause. Mortality rate was 44%. Increasing grade of encephalopathy, >7 days interval between the onset of prodromal symptoms and encephalopathy, blood glucose <45mg/dL, serum bilirubin > 10mg/dL and pH <7.35 or >7.45 on admission were found to be associated with increased risk of mortality.

Abstract
BACKGROUND Acute liver failure (ALF) is a clinical syndrome with very high mortality estimates ranging between 60% and 80%. AIM To investigate the explicitness and extent of variability in the used ALF definitions in the ALF prognostic literature. METHODS All studies that pertain to the prognosis of patients with ALF were electronically searched in MEDLINE (1950-2012) and EMBASE (1950-2012). Identified titles and abstracts were independently screened by three reviewers to determine eligibility for additional review. We included English articles that reported original data from clinical trials or observational studies on ALF patients. RESULTS A total of 103 studies were included. Of these studies 87 used 41 different ALF definitions and the remaining 16 studies did not report any explicit ALF definition. Four components underlying ALF definitions accounted for the differences: presence and/or grading of hepatic encephalopathy (HE); the interval between onset of disease and occurrence of HE; presence of coagulopathy and pre-existing liver disease. CONCLUSIONS The diversity in acute liver failure definitions hinders comparability and quantitative analysis among studies. There is room for improvement in the reporting of acute liver failure definitions in prognostic studies. The result of this review may be useful as a starting point to create a uniform acute liver failure definition.

Abstract
Acute liver failure (ALF) is a clinical syndrome associated with significant morbidity and mortality with a highly unpredictable outcome. We retrospectively analyzed 71 ALF patients (53 males; mean age = 27.5 ± 15.6 years) that underwent transjugular liver biopsy (TJLB) at our institution. The aims of this study are (i) to report our experience with TJLB in these patients, and (ii) to examine the role of liver histology in predicting their outcome. We also compared the histopathological findings between TJLB and explanted liver specimens in 31 patients who underwent liver transplantation (LT). Biopsy specimens were satisfactory for histopathological analyses in 69 (97.1%) patients, confirmed the clinical diagnosis in 56 (81.2%) patients, and altered the diagnosis in 13 (18.8%) patients. Minor complications were encountered in four (5.6%) patients. Percentage of hepatocyte necrosis was the only histological parameter that has significant discriminatory prognostic value, with no survivors having >75% necrosis without LT. In conclusions, TJLB is a safe technique for obtaining liver tissue in both adult and pediatric patients with ALF. Histological characteristics, mainly etiological diagnosis and degree of hepatocyte necrosis may assist in clinical decision-making for need of LT in these patients.

Abstract
BACKGROUND Patients with acute liver failure are classified according to the interval between the onset of hepatitis symptoms and the development of hepatic encephalopathy. We examined the validity of such classifications. METHODS The subjects were 1,022 patients enrolled in a nationwide survey in Japan. The intervals between the onset of the hepatitis symptoms and the development of encephalopathy were 10 days or less in 472 patients (group-A), between 11 and 56 days in 468 patients (group-B), and longer than 56 days in 82 patients (group-C). Data on a total of 104 items collected from the patients were subjected to clustering using a self-organizing map. RESULTS The patients were classified into three clusters. The first cluster consisted of 411 patients (group-A: 57%, group-B: 39%, group-C: 4%). Their incidence of complications was low; 34% underwent liver transplantation (LT), and their survival rate was 90%, while 94% of those treated without transplant were rescued. The second cluster consisted of 320 patients (21, 65, and 14% groups A, B, and C, respectively), who showed a high incidence of complications; the survival rate was 7% in the patients treated conservatively without LT. Sixteen percent underwent LT and survival rate of these patients was 52%. There was a third cluster, of 291 patients (59, 34, and 7% groups A, B, and C, respectively). Without LT, 81% of the patients died. Seven percent were treated by LT and their survival rate was 60%. CONCLUSIONS Clustering revealed that patients with acute liver failure could be classified into three clusters independent of the interval between the onset of disease symptoms and the development of encephalopathy. This technique may be useful, since the outcomes of the patients differed markedly among the clusters.

Abstract
OBJECTIVE Fulminant hepatitis B is a clinical syndrome that results from massive necrosis of liver cells leading to the development of hepatic encephalopathy. The aim of this study was to evaluate the efficacy of lamivudine in patients with fulminant hepatitis B and study the prognostic factors. METHODS A matched retrospective cohort study using data on fulminant hepatitis B patients derived from our hospital database was conducted. Forty patients receiving lamivudine treatment were selected into the lamivudine treatment group with another 40 without lamivudine treatment studied as control. They were matched for sex, age and HBeAg status with lamivudine treatment group. The mortality of patients in two groups was compared. The influential factors on the mortality were studied by Cox proportional hazards model. RESULTS The mortality of patients in the lamivudine group (n=38) was significantly lower than that of the control group (n=39) (63.2 vs. 84.6%; χ(2) =4.609, P=0.032). For patients without systemic inflammatory response syndrome (SIRS), the mortality of patients in the lamivudine group (n=25) was significantly lower than that of the control group (n=26) (52.0 vs. 80.8%; χ(2) =4.747, P=0.029). In multivariate Cox proportional hazards analyses, for patients without SIRS, age (P=0.037), ratio of total to direct bilirubin (P=0.008), treatment method (P=0.005) and the decline of hepatitis B virus (HBV) DNA load during therapy (P=0.019) were independent predictors of prognosis. CONCLUSIONS Treatment with lamivudine significantly decreases the mortality of fulminant hepatitis B patients without SIRS, and a rapid decline of HBV DNA load is one of the good predictors for the treatment outcome.

Accuracy of MELD scores in predicting mortality in decompensated cirrhosis from variceal bleeding, hepatorenal syndrome, alcoholic hepatitis, or acute liver failure as well as mortality after non-transplant surgery or TIPS. Dig Dis Sci 2011; 56:977-87.

Abstract
BACKGROUND To systematically review literature on use of model for end-stage liver disease (MELD) score to determine severity and prognosis of liver disease in various clinical situations and to evaluate its use in decisions regarding therapeutic interventions. METHODS Computerized literature searches using key medical terms; review of authors' extensive files on this subject; and personal clinical experience. RESULTS The MELD score, a prospectively developed and validated scale for severity of end-stage liver disease, utilizes serum bilirubin, serum creatinine, and international normalized ratio to predict mortality in cirrhotic patients. It has proven clinically useful in increasingly varied clinical situations. The United Network for Organ Sharing uses MELD scores, with bonus points assigned for hepatocellular cancer, to prioritize allocation of deceased donor livers for liver transplantation. This work reviews recent data demonstrating that MELD scores relatively accurately predict mortality in patients with variceal bleeding, hepatorenal syndrome, alcoholic hepatitis, and acute liver failure, as well as assess risks of non-liver transplantation surgery or transjugular intrahepatic portosystemic shunts in cirrhotic patients. MELD scores fail to predict mortality in about 15% of patients with end-stage liver disease. Incorporation of additional parameters, including serum sodium level, serum albumin level, glucose intolerance, or APACHE II score, may potentially improve prognostic accuracy. CONCLUSIONS MELD scores relatively accurately assess severity of liver disease and prognosis in patients with advanced liver disease in general, and in patients with individual complications of liver disease. It is useful in making decisions on potential therapies. Incorporating additional parameters may further improve its prognostic accuracy.

Abstract
Patients with acute liver failure are a particularly challenging group, with unique difficulties faced in treatment decisions. Life-saving therapy is available, but organ shortage, delays in transplantation, and complications in management result in a high mortality in this group of patients even after transplant. Any pharmacologic intervention that improved outcomes in this population of critically ill patients would be of great benefit. Based on available evidence, different scenarios of participation of HSCs in liver recovery are conceivable. Encouraging HSCs to differentiate into hepatocytes or supply paracrine and cellular level support to accelerate ongoing local repair mechanisms and assist a failing liver with inadequate mass and functional capacity might be directed to occur effectively in humans. Evidence within small animal models of liver injury and observations within the human population suggest that this might also be encouraged. The use of pharmacologic agents to mobilize hematopoietic stem cells is well established and effectively used in a different population of patients. As such, extending the use of these drugs, such as plerixafor, to the human population has a sound basis. However, there is a need for clarification of the mechanisms by which these cells exert their effect as well as which specific population of cells is involved in the regenerative process. To be clinically relevant in scenarios of acute liver failure, stem cell mobilizing strategies would have to impact survival when administered well after injury. Applications in other settings may also prove useful. Limits to liver resection exist where the size of the future liver remnant governs the extent of resection possible. Preexisting functional impairment may be restrictive, and strategies involving stem cells may assist the future liver remnant in both normal and functionally impaired livers. Benefit has already been reported from treatment with G-CSF in other injured tissues, including the injured myocardium and acutely injured kidney. However, as yet no clinical trial exists to assess the effects of stem cell mobilization in humans with acute liver failure. The familiarity in the use of and success demonstrated in the clinical and experimental use of plerixafor and G-CSF make exploration of hematopoietic stem cells as therapy in patients with acute liver failure appealing.

Abstract
UNLABELLED Acute liver failure (ALF) due to drug-induced liver injury (DILI), though uncommon, is a concern for both clinicians and patients. The Acute Liver Failure Study Group has prospectively collected cases of all forms of acute liver failure since 1998. We describe here cases of idiosyncratic DILI ALF enrolled during a 10.5-year period. Data were collected prospectively, using detailed case report forms, from 1198 subjects enrolled at 23 sites in the United States, all of which had transplant services. A total of 133 (11.1%) ALF subjects were deemed by expert opinion to have DILI; 81.1% were considered highly likely, 15.0% probable, and 3.8% possible. Subjects were mostly women (70.7%) and there was overrepresentation of minorities for unclear reasons. Over 60 individual agents were implicated, the most common were antimicrobials (46%). Transplant-free (3-week) survival was poor (27.1%), but with highly successful transplantation in 42.1%, overall survival was 66.2%. Transplant-free survival in DILI ALF is determined by the degree of liver dysfunction, specifically baseline levels of bilirubin, prothrombin time/international normalized ratio, and Model for End-Stage Liver Disease scores. CONCLUSION DILI is an uncommon cause of ALF that evolves slowly, affects a disproportionate number of women and minorities, and shows infrequent spontaneous recovery, but transplantation affords excellent survival.

Abstract
BACKGROUND & AIMS Current techniques for predicting outcome and requirement for emergency liver transplantation (ELT) in acute liver failure (ALF) are imperfect, though The Kings College Criteria (KCC) are the most commonly applied tools for this purpose. Their performance in identification of patients with non-paracetamol-induced ALF (non-POD ALF), who would not survive without ELT, has recently been questioned. Using quantitative techniques, we therefore performed a meta-analysis of outcome data of the KCC for prediction of survival in non-POD ALF. METHODS A systematic database search was performed and retrieved articles graded according to a pre-agreed pro-forma of methodological quality. Collated data was meta-analysed for summary sensitivity, specificity, diagnostic odds ratio (DOR) and ROC curve analysis. Pre-specified sub-group analysis was performed on the basis of methodological quality, the severity of hepatic encephalopathy (HE) of reported patients, timing of KCC application and exclusion of those who underwent ELT. RESULTS Eighteen studies with data on 1105 patients were available for production of 2x2 tables. Summary sensitivity was 68 (95% CI 59-77)%, specificity 82 (75-88)% and DOR 12.6 (6.5-26.1). Heterogeneity was detected in the DOR and related to methodological quality (I(2)=64% for all studies versus 47% for 'good' quality studies) and was lower in studies considering high grade HE or dynamic application of KCC (I(2)=0%). For data where ELT were excluded (13 studies) summary sensitivity was 68 (57-79)%, specificity 81 (72-90)% and DOR 12.2 (4.9-30.1) and a symmetric summary ROC curve was produced. Specificity was highest in studies of patients with high grade HE (93 (80-100)%) and where KCC were applied dynamically through the clinical course (88 (78-97)%). Sensitivity was reduced in studies published post 2005 compared with studies pre 1995 (58 (46-71)% versus 85 (76-82)%). CONCLUSIONS KCC for outcome in non-POD ALF have good specificity and more limited sensitivity. There is significant heterogeneity in the published data partially related to methodological quality. KCC perform best in groups with high grade encephalopathy and in historically earlier studies suggesting modern medical management of ALF may modify performance of KCC.

Abstract
The key elements that determine the host response to either the self-limited or a severe fulminant form of liver disease are unclear. We have investigated the potential association of single nucleotide polymorphisms (SNPs) in the promoter region of tumor necrosis factor-alpha (TNFalpha) in their susceptibility to acute viral hepatitis (AVH) and fulminant hepatic failure (FHF) patients exhibiting specific viral etiology. A total of 124 individuals including 64 cases comprising 27 FHF, 37 AVH, and 60 healthy controls were recruited. SNPs at -238 (G/A), -308 (G/A), -857 (C/T), and -863 (C/A) of TNFalpha were detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and confirmed by direct sequencing. Serum levels of TNFalpha were determined at admission and death or recovery. Association between the TNFalpha genotype and susceptibility to FHF was not evident; however, carrier genotypes in relation to the -308 (GA/AA) and -857 (CT/TT) loci were found to be significantly (P < or = 0.05) associated with susceptibility to AVH in relation to controls. The mean TNFalpha serum levels at admission were significantly higher (P < 0.001) in FHF than AVH patients, but no marked difference was observed between FHF-E (expired; n = 17) and FHF-S (survivors; n = 10), though the former were comparatively higher. This study suggests that SNPs at -308 and -857 of the TNFalpha promoter may represent an increased risk for the development of AVH but not for FHF in the Indian population.

Abstract
BACKGROUND AND AIM Severe acute hepatitis B is a rapid deterioration of liver function, which carries a high mortality rate. The aim of this study is to evaluate the efficacy of lamivudine in patients with severe acute hepatitis B. METHODS In this study, 80 patients with severe acute hepatitis B were randomly divided into lamivudine and the control group. For the two groups, we compared HBsAg, HBeAg seroconversion rates, serum HBV DNA-negative rate, biochemical indicators, the incidence of liver failure, and mortality. The influential factors on the mortality were studied by Cox proportional hazards model. RESULTS The improvement in serum TBiL, INR, and HBV DNA levels of the lamivudine group was significantly greater than that of the control group. The mortality of lamivudine group (7.5%, 3/40) was significantly lower than that of the control group (25.0%, 10/40) (p = 0.034). The incidence of liver failure (8.7%, 2/23) of patients receiving lamivudine within a week was significantly lower than that (35.3%, 6/17) of those who received it after a week (p = 0.038). In multivariate Cox proportional hazards analyses, age (p = 0.043), ratio of total to direct bilirubin (p = 0.009), treatment method (p = 0.006), and the decline of HBV DNA load during therapy (p = 0.017) were independent predictors of mortality. The HBsAg seroconversion rates (62.5%, 25/40) and HBeAg seroconversion rates (63.6%, 21/33) of the lamivudine group were significantly lower than those (85.0%, 34/40), (87.5%, 28/32) of the control group (p = 0.022, 0.026). CONCLUSIONS Early treatment with lamivudine leads to a greater decrease in HBV DNA level, better clinical improvement and mortality improvement in patients with severe acute hepatitis B, but with a lower seroconversion rate. A rapid decline of HBV DNA load is a good predictor for the treatment outcome.

Abstract
Acute liver failure continues to be associated with a high mortality rate, and emergency liver transplantation is often the only life-saving treatment. The short-term outcomes are decidedly worse in comparison with those for nonurgent cases, whereas the long-term results have not been reported as extensively. We report our center's experience with urgent liver transplantation, long-term survival, and major complications. From 1994 to 2007, 60 patients had emergency liver transplantation for acute liver failure. The waiting list mortality rate was 6%. The mean waiting time was 2.7 days. Post-transplantation, the perioperative mortality rate was 15%, and complications included neurological problems (13%), biliary problems (10%), and hepatic artery thrombosis (5%). The 5- and 10-year patient survival rates were 76% and 69%, respectively, and the graft survival rates were 65% and 59%. Recipients of blood group-incompatible grafts had an 83% retransplantation rate. Univariate analysis by Cox regression analysis found that cerebral edema and extended criteria donor grafts were associated with worse long-term survival. Severe cerebral edema on a computed tomography scan pre-transplant was associated with either early mortality or permanent neurological deficits. The keys to long-term success and continued progress in urgent liver transplantation are the use of good-quality whole grafts and a short waiting list time, both of which depend on access to a sufficient pool of organ donors. Severe preoperative cerebral edema should be a relative contraindication to transplantation.

Abstract
Older age is considered a poor prognostic factor in acute liver failure (ALF) and may still be considered a relative contraindication for liver transplantation for ALF. We aimed to evaluate the impact of older age, defined as age > or = 60 years, on outcomes in patients with ALF. One thousand one hundred twenty-six consecutive prospective patients from the US Acute Liver Failure Study Group registry were studied. The median age was 38 years (range, 15-81 years). One thousand sixteen patients (90.2%) were younger than 60 years (group 1), and 499 (49.1%) of these had acetaminophen-induced ALF; this rate of acetaminophen-induced ALF was significantly higher than that in patients > or = 60 years (group 2; n = 110; 23.6% with acetaminophen-induced ALF, P < 0.001). The overall survival rate was 72.7% in group 1 and 60.0% in group 2 (not significant) for acetaminophen patients and 67.9% in group 1 and 48.2% in group 2 for non-acetaminophen patients (P < 0.001). The spontaneous survival rate (ie, survival without liver transplantation) was 64.9% in group 1 and 60.0% in group 2 (not significant) for acetaminophen patients and 30.8% in group 1 and 24.7% in group 2 for non-acetaminophen patients (P = 0.27). Age was not a significant predictor of spontaneous survival in multiple logistic regression analyses. Group 2 patients were listed for liver transplantation significantly less than group 1 patients. Age was listed as a contraindication for transplantation in 5 patients. In conclusion, in contrast to previous studies, we have demonstrated a relatively good spontaneous survival rate for older patients with ALF when it is corrected for etiology. However, overall survival was better for younger non-acetaminophen patients. Fewer older patients were listed for transplantation.

Abstract
BACKGROUND/AIM Fulminant hepatic failure (FHF) is a devastating complication of acute viral hepatitis, leading to death in most cases. The etiology and predictors of outcome differ according to the geographical region. This study was conducted with the aim of evaluating the etiology, complications, and outcome of FHF in Bangladesh. PATIENTS AND METHODS In this prospective study, we included 67 consecutive cases of FHF presenting to the Department of Hepatology, Bangabandhu Sheikh Mujib Medical University, Dhaka, between November 2003 and May 2008. Thirty-nine of the patients were male and 28 were female. Data was analyzed using SPSS, version 13.0. RESULTS The mean age of the subjects was 31.9 +/- 11 .7 years. Hepatitis E virus (HEV) was the commonest etiological factor for FHF (50 cases, 74.6%); of the 50 cases with HEV infection, 43 (64.2%) were not coinfected with any other virus, four cases were Hepatitis B virus (HBV) carriers, and three had coinfection with hepatitis A virus (HAV). HBV was the cause of FHF in nine (13.4%) patients. HCV, paracetamol, and alcohol were not responsible for any of the cases. Most of the patients (57 patients, 85%) developed FHF within 2 weeks of the onset of jaundice. Of the 67 patients, 49 (73.1%) died. Cerebral edema was the single most common cause of death (48 patients, 71.6%). Other complications were renal failure (23 patients, 34.3%), sepsis (15 patients, 22.4%), electrolyte imbalance (12 patients 17.9%), and bleeding tendency (7 patients, 10.4%). Occurrence of cerebral edema, longer prothrombin time, higher grade of encephalopathy, and longer jaundice-to-encephalopathy interval had significant negative influence on outcome. CONCLUSIONS The etiology of FHF in Bangladesh is different from that in the West. Prolongation of prothrombin time and occurrence of cerebral edema are predictors of the worst prognosis.

Abstract
OBJECTIVES Cytokines as prognostic markers in acute liver failure (ALF) have not been evaluated in the Indian subcontinent with hepatitis E as the commonest aetiological agent. We investigated the clinical significance of proinflammatory/apoptotic cytokines soluble Fas ligand (sFasL) and tumour necrosis factor (TNF)-alpha in ALF of specific aetiology. METHODS A total of 82 cases, 37 ALF and 45 acute hepatitis (AH), and 60 healthy controls were recruited. Serum levels of sFasL and TNF-alpha were determined at admission and death/recovery. RESULTS Mean sFasL and TNF-alpha serum levels at admission were significantly higher (p < 0.001) in patients with ALF than AH, but no marked difference was observed between ALF-E (expired, n = 23) and ALF-S (survivors, n = 14), although the former had comparatively higher levels. ALF-E had higher than baseline TNF-alpha and sFasL concentrations at death, while in the ALF-S group the samples obtained from the patients as soon as they came out of encephalopathy, showed either lower or similar TNF-alpha and sFasL levels as found at admission. CONCLUSION The high levels of sFasL and TNF-alpha are associated with ALF. Following the trend of these cytokines can be useful in predicting death and timely referral to a transplant centre.

Abstract
BACKGROUND Acute liver failure (ALF) is a clinical syndrome characterized by the sudden onset of coagulopathy and encephalopathy. The outcome is unpredictable and is associated with high morbidity and mortality. We reviewed our experience to identify the aetiology and study the outcome of acute liver failure. METHODS A total of 1237 patients who presented with acute liver failure between January 1992 and May 2008 were included in this retrospective study. Liver transplantation was undertaken based on the King's College Hospital criteria. Data were obtained from the units prospectively collected database. The following parameters were analysed: patient demographics, aetiology, operative intervention, overall outcome, 30-day mortality and regrafts. RESULTS There were 558 men and 679 women with a mean age of 37 years (range: 8-78 years). The most common aetiology was drug-induced liver failure (68.1%), of which 90% was as a result of a paracetamol overdose. Other causes include seronegative hepatitis (15%), hepatitis B (2.6%), hepatitis A (1.1%), acute Budd-Chiari syndrome (1.5%), acute Wilson's disease (0.6%), subacute necrosis(3.2%) and miscellaneous (7.8%). Three hundred and twenty-seven patients (26.4%) were listed for liver transplantation, of which 263 patients successfully had the procedure (80.4%). The current overall survival after transplantation was 70% with a median follow-up of 57 months. After transplantation for ALF, the 1-year, 5-year and 10-year survival were 76.7%, 66% and 47.6%, respectively. The 30-day mortality was 13.7%. Out of the 974 patients who were not transplanted, 693 patients are currently alive. Among the 281 patients who died without transplantation, 260 died within 30 days of admission (26.7%). Regrafting was performed in 31 patients (11.8%), the most common indication being hepatic artery thrombosis (11 patients). CONCLUSION Paracetamol overdose was the most common cause of acute liver failure. Liver transplantation, when performed for acute liver failure, has good long-term survival.

Abstract
BACKGROUND AND AIM Acute liver failure (ALF) remains a devastating disease carrying considerable mortality. Since deceased donor liver transplantation is rarely performed in Japan, the artificial liver support system (ALS) and living donor liver transplantation (LDLT) are the main modalities used for treatment of ALF. The aim of this study was to analyze the outcome of ALF patients and to evaluate therapies for ALF according to etiology. METHODS Fifty consecutive patients with ALF were treated between January 1990 and December 2006. Prior to 1997, patients received ALS only. After 1997, ALS and/or LDLT were applied. LDLT was performed in 10 patients. RESULTS Four of 15 (27%) pre-1997 ALF patients survived, and 16 of 35 (46%) post-1997 ALF patients survived, including eight who underwent LDLT. The causes of ALF were acute hepatitis B virus (HBV) infection in 18%, severe acute exacerbation (SAE) of chronic HBV infection in 18%, autoimmune hepatitis (AIH) in 8%, and cryptogenic hepatitis in 44%. In total, 67% of the patients with ALF caused by acute HBV infection and AIH were cured without LDLT; only 11% of patients with ALF caused by SAE of HBV and 24% of cryptogenic hepatitis were successfully treated without LDLT. Notably, 80% of patients with cryptogenic hepatitis who underwent LDLT survived. CONCLUSION Since 1997, the survival rate of ALF patients has increased, mainly due to the introduction of LDLT. Liver transplantation should be performed especially in patients with ALF caused by SAE of HBV and cryptogenic hepatitis.

Abstract
OBJECTIVE To determine the clinical characteristics of patients with acute liver failure of indeterminate cause and their long-term outcome in comparison with patients with acute liver failure of obvious aetiology (acetaminophen and mushroom poisoning, Budd-Chiari syndrome, acute viral hepatitis) and other controls (idiosyncratic drug reactions, autoimmune hepatitis and Wilson's disease). MATERIAL AND METHODS All patients with acute liver failure and listed for liver transplantation in Sweden between 1984 and 2006 were included in a retrospective analysis. RESULTS A total of 71 patients with acute liver failure were identified, 33 with indeterminate cause (IDC group), 23 with obvious aetiology (OE group) and 15 other controls (OC group). Before admission to the transplant centre, IDC patients were hospitalized in the referring hospital for 9 days (4-15) versus 1.5 days (1-3) in the OE group (p<0.001) and 7 days (2-14) in the OC group (NS). Serum bilirubin was higher (p<0.001), whereas peak creatinine was lower (p=0.001) in the IDC group compared with the OE group but was not significantly different from the OC group. There were no significant differences in 1-, 3-, 5- and 10-year patient and graft survival rates between the IDC group and the OE or the OC group. CONCLUSIONS Patients with acute liver failure of indeterminate cause seem to differ from those with obvious aetiology in clinical and biochemical presentation but are similar to other controls. The overall long-term outcome seems to be similar in patients with an unknown aetiology as in those with a specific aetiology.

Abstract
BACKGROUND Living donor liver transplantation has become an accepted treatment for various terminal liver diseases. STUDY DESIGN Forty-two living donor liver transplantations performed for acute liver failure during a 10-year period at Kyushu University Hospital were reviewed. RESULTS Causes of liver failure included hepatitis B (n=12), hepatitis C (n=1), autoimmune hepatitis (n=2), Wilson's disease (n=3), and unknown causes (n=24). The graft types were: left lobe (n=33), right lobe (n=8), and lateral segment (n=1). The mean graft volume to standard liver volume ratios were 42.2+/-9.2% in left lobe grafts and 50.5+/-3.9% in right lobe grafts (p < 0.05). Extubation was significantly delayed in grade IV encephalopathy patients (73.7 +/-18.2 hours) compared with patients with other grades (p < 0.01 to grades I and II, p < 0.05 to grade III). All other patients, except one with a subarachnoid hemorrhage, had complete neurologic recovery after transplantation. The 1- and 10-year survival rates were 77.6% and 65.5%, respectively, for grafts, and 80.0% and 68.2%, respectively, for patients. CONCLUSIONS Outcomes of living donor liver transplantation for acute liver failure are fairly acceptable despite severe general conditions and emergent transplant settings. Living donor liver transplantation is now among the currently accepted life-saving treatments of choice for acute liver failure, although innovative medical treatments for this disease entity are still anticipated.

Abstract
Assessment of prognosis in fulminant hepatic failure (FHF) is essential for the need and appropriate timing of orthotopic liver transplantation (OLT). In this study we investigated the prognostic efficacy of King's College criteria, Clichy's criteria, Model for End-Stage Liver Disease (MELD), and Pediatric End-Stage Liver Disease (PELD) in 120 consecutive patients with FHF. Survival with medical therapy (18%), death without OLT (15%), and receipt of a liver transplant were similar in adults (n = 64) and children (n = 56). MELD scores were significantly higher in patients who died compared to those who survived without OLT, both in adults (38 +/- 7 vs. 26 +/- 7, P = 0.0003) and children (39 +/- 7 vs. 23 +/- 6, P = 0.0004). Using logistic regression analysis in this cohort of patients, concordance statistics were significantly higher for MELD (0.95) and PELD (0.99) when compared to King's College (0.74) and Clichy's criteria (0.68). When data was analyzed in a Cox model including patients receiving transplants and censoring the time from admission, the concordance statistic for MELD (0.77) and PELD (0.79) remained significantly higher than that of King's College criteria but not higher than that of Clichy's criteria. In conclusion, this study is the first to show that MELD and PELD are superior to King's College and Clichy's criteria to assess prognosis in FHF. However, because data was generated from a single center and included a rather low number of patients who survived or died without OLT, further confirmation of our findings is required.

Abstract
BACKGROUND Distinguishing those patients with fulminant hepatic failure (FHF) and who require transplantation from those FHF patients who will survive with receiving only intensive medical care remains problematic, and this distinction is important because of the chronic shortage of donor livers. METHODS To assess the applicability of two prognostic scoring systems, referred to as the London and Clichy criteria, we compared using both systems, at the time of admission, for 43 FHF patients (15 M/28 F; age: 3716 yrs). Acetaminophen (ACM) was the etiology for 16 patients, while the remaining 27 had other etiologies. All the patients received intensive care, and 18 (8 ACM/10 non-ACM) had investigational BAL support. RESULTS For the ACM toxicity, neither the London nor the Clichy criteria exhibited acceptable sensitivity (71 vs 86%, respectively), specificity (78 vs 56%, respectively), a positive predictive value (71 vs 60%, respectively), a negative predictive value (78 vs 83%, respectively) or predictive accuracy (75 vs 69%, respectively) to predict patient survival without transplantation. In contrast, applying the London and Clichy criteria to the FHF patients with non-ACM etiologies showed a sensitivity of 96 vs 80%, respectively, a specificity of 100 vs 100%, respectively, a positive predictive value of 100 vs 100%, respectively a negative predictive value of 67 vs 29%, respectively and a predictive accuracy of 96% vs 82%, respectively. CONCLUSIONS Overall, the London criteria more accurately predicted the need for transplantation, and neither the London criteria nor the Clichy prognostic criteria accurately predicted the outcome of those patients who suffered with FHF due to ACM. BAL support may have contributed to the survival of the patients with ACM toxicity and who didn't undergo transplantation, and this survival exceeded the predictions of both prognostic systems. Additional multicenter studies should be conducted to refine these prognostic scoring systems, and this will help physicians rapidly identify those FHF patients who can survive without undergoing liver transplantation.

Abstract
While King's Hospital Criteria (KCH) criteria are used worldwide, the Model for End-Stage Liver Disease (MELD) is a more recently developed scoring system that has been validated as an independent predictor of patient survival in conditions for liver transplantation (LT). The aim of the present study was to compare MELD and KCH criteria with other early clinical prognostic indicators (CPI) in a cohort of patients with fulminant hepatic failure (FHF). A total of 144 patients (mean age 31.7 +/- 14.7 yr; range 12-82 yr; 62 males) with FHF due to acute viral hepatitis were included into the study. Variables found significant on univariate analysis were entered into a multivariate logistic regression analysis. A total of 52 (36.1%) patients survived, the remaining 92 (63.9%) died. Univariate analysis showed that age, duration of jaundice, jaundice-encephalopathy interval (JEI), grade of encephalopathy, presence of cerebral edema, bilirubin, prothrombin time, creatinine, and MELD score were significantly different between survivors and nonsurvivors. Multivariate logistic regression identified 6 independent CPI of adverse outcome on admission: age >or=50 yr, JEI >7 days, grade 3 or 4 encephalopathy, presence of cerebral edema, prothrombin time >or=35 seconds, and creatinine >or=1.5 mg/dL. Presence of any 3 of 6 CPI was optimum in identifying survivors and nonsurvivors. A MELD score of >or=33 was found to be best discriminant between survivors and nonsurvivors by the construction of receiver operating characteristic (ROC) curves. Any 3 CPI were superior to MELD and KCH criteria in predicting the outcome (c-statistic [95% confidence interval]: CPI 0.802 [0.726-0.878], MELD 0.717 [0.636-0.789], and KCH criteria 0.676 (0.588-0.764); P values: CPI vs. MELD 0.045, CPI vs. KCH criteria 0.019, and MELD vs. KCH criteria 0.472). In conclusion, MELD and KCH criteria are not as useful as a combination of other early CPI in predicting adverse outcome in patients with FHF due to acute viral hepatitis.
