Abstract
BACKGROUND The timing and selection of patients for liver transplantation in acute liver failure are great challenges. This study aimed to investigate the effect of Glasgow coma scale (GCS) and APACHE-II scores on liver transplantation outcomes in patients with acute liver failure. METHOD A total of 25 patients with acute liver failure were retrospectively analyzed according to age, etiology, time to transplantation, coma scores, complications and mortality. RESULTS Eighteen patients received transplants from live donors and 7 had cadaveric whole liver transplants. The mean duration of follow-up after liver transplantation was 39.86+/-40.23 months. Seven patients died within the perioperative period and the 1-, 3-, 5-year survival rates of the patients were 72%, 72% and 60%, respectively. The parameters evaluated for the perioperative deaths versus alive were as follows: the mean age of the patients was 33.71 vs 28 years, MELD score was 40 vs 32.66, GCS was 5.57 vs 10.16, APACHE-II score was 23 vs 18.11, serum sodium level was 138.57 vs 138.44 mmol/L, mean waiting time before the operation was 12 vs 5.16 days. Low GCS, high APACHE-II score and longer waiting time before the operation (P<0.01) were found as statistically significant factors for perioperative mortality. CONCLUSION Lower GCS and higher APACHE-II scores are related to poor outcomes in patients with acute liver failure after liver transplantation.

Abstract
Mushroom poisoning is a relatively rare cause of acute liver failure (ALF). The present paper analyzes the pathogenesis, clinical features, prognostic indicators, and therapeutic strategies of ALF secondary to ingestion of Amanita phalloides, which represents the most common and deadly cause of mushroom poisoning. Liver damage from Amanita phalloides is related to the amanitins, powerful toxins that inhibit RNA polymerase II resulting in a deficient protein synthesis and cell necrosis. After an asymptomatic lag phase, the clinical picture is characterized by gastrointestinal symptoms, followed by the liver and kidney involvement. Amatoxin poisoning may progress into ALF and eventually death if liver transplantation is not performed. The mortality rate after Amanita phalloides poisoning ranges from 10 to 20%. The management of amatoxin poisoning consists of preliminary medical care, supportive measures, detoxification therapies, and orthotopic liver transplantation. The clinical efficacy of any modality of treatment is difficult to demonstrate since randomized, controlled clinical trials have not been reported. The use of extracorporeal liver assist devices as well as auxiliary liver transplantation may represent additional therapeutic options.

Abstract
One of the major causes of mortality in patients with acute liver failure (ALF) is the development of hepatic encephalopathy (HE) which is associated with increased intracranial pressure (ICP). High ammonia levels, increased cerebral blood flow and increased inflammatory response have been identified as major contributors to the development of HE and the related brain swelling. The general principles of the management of patients with ALF are straightforward. They include identifying the insult causing hepatic injury, providing organ systems support to optimize the patient's physical condition, anticipation and prevention of development of complications. Increasing insights into the pathophysiological mechanisms of ALF are contributing to better therapies. For instance, the evident role of cerebral hyperemia in the pathogenesis of increased ICP has led to a re-evaluation of established therapies such as hyperventilation, N-acetylcysteine, thiopentone sodium and propofol. The role of systemic inflammatory response in the pathogenesis of increased ICP has also gained importance supporting the concept that antibiotics given prophylactically reduce the risk of developing sepsis during the course of illness. Moderate hypothermia has also been established as a therapy able to reduce ICP in patients with uncontrolled intracranial hypertension and to prevent increases in ICP during orthopic liver transplantation. Ornithine phenylacetate, a new drug in the treatment of liver failure, and liver replacement therapies are still being investigated both experimentally and clinically. Despite many advances in the understanding of the pathophysiological basis and the management of intracranial hypertension in ALF, more clinical trials should be conducted to determine the best therapeutic management for this difficult clinical event.

Abstract
Acute liver failure is a disorder which impacts on multiple organ systems and results from hepatocellular necrosis in a patient with no previous history of chronic liver disease. It typically culminates in the development of liver dysfunction, coagulopathy and encephalopathy, and is associated with high mortality in poor prognostic groups. In acute liver failure, some patients may develop cerebral edema and increased intracranial pressure although recent data suggest that intracranial hypertension is less frequent than previously described, complicating 29% of acute cases who have proceeded to grade 3/4 coma. Neurological manifestations are primarily underpinned by the development of brain edema. The onset of encephalopathy can be rapid and dramatic with the development of asterixis, delirium, hyperreflexia, clonus, seizures, extensor posturing and coma. Ammonia plays a definitive role in the development of cytotoxic brain edema. Patients with acute liver failure have a marked propensity to develop renal insufficiency and hence impaired ammonia excretion. The incidence of both bacterial and fungal infection occurs in approximately one third of patients. The relationship between inflammation, as opposed to infection, and progression of encephalopathy is similar to that observed in chronic liver disease. Intracranial pressure monitoring is valuable in identifying surges in intracranial hypertension requiring intervention. Insertion of an intracranial bolt should be considered only in the subgroup of patients who have progressed to grade 4 coma. Risk factors for developing intracranial hypertension are those with hyperacute and acute etiologies, progression to grade 3/4 hepatic encephalopathy, those who develop pupillary abnormalities (dilated pupils, sluggishly responsive to light) or seizures, have systemic inflammation, an arterial ammonia >150 μmol/L, hyponatremia, and those in receipt of vasopressor support. Strategies employed in patients with established encephalopathy (grade 3/4) aim to maintain freedom from infection/inflammatory milieu, provide adequate sedation, and correct hypo-osmolality.

Abstract
AIM: To examine the epidemiologic and clinical characteristics of hepatitis B virus (HBV) related liver failure in patients in China.
METHODS: This study was conducted with a retrospective design to examine 1066 patients with HBV-related liver failure in the southwest of China.
RESULTS: There were more male than female patients. Young and middle-aged people comprised most of the patients. Farmers and laborers comprised the largest proportion (63.09%). Han Chinese accounted for 98.12%, while minority ethnic groups only accounted for 0.88% of patients. A total of 43.47% patients had a family history of HBV-related liver failure and 56.66% patients had a history of drinking alcohol. A total of 42.59% patients with HBV-related liver failure had definite causes. With regard to the clinical manifestation of HBV-related liver failure, the symptoms were: hypodynamia, anorexia and abdominal distension. Total bilirubin (TBIL) and alanine aminotransferase (ALT) levels were altered in 46.23% of patients with evident damage of the liver. Univariate logistic regression analysis showed that the patients’ prognoses were correlated with ALT, aspartate aminotransferase, albumin, TBIL, prothrombin activity (PTA), and alpha-fetoprotein levels, and drinking alcohol, ascites, hepatorenal syndrome, infection and ≥ 2 complications. Multifactor logistic regression analysis showed that the activity of thrombinogen and the number of complications were related to the prognosis.
CONCLUSION: Alcohol influences the patients’ prognosis and condition. PTA and complications are independent factors that can be used for estimating the prognosis of HBV-related liver failure.

Abstract
BACKGROUND/AIMS The aim of our study was to provide a predictive model for early recognition of the risk of short-term development of hepatic encephalopathy (HE) in patients with symptomatic acute liver disease (ALD). METHODS From a retrospective analysis of 220 patients with ALD, prothrombin time (PT) equal to, or lower than, 80% of normal, was set as the registration criteria in the subsequent patient cohorts of the study. Then, a HE-prediction model was derived by a logistic regression analysis of data in 259 new patients, and prospectively validated in 124 other patients, both groups of patients were affected by ALD unrelated to paracetamol (non-P ALD). RESULTS The following HE-prediction model was established: lambda = [0.692 x ln(1 + total bilirubin(mg/dL))] - 0.065 x PT(%) + [1.388 x Age(years)] + [0.868 x Etiology] - 1.156, where Age is 1 in patients older than 50 years and Etiology is 1 when the cause of non-P ALD is flare-up of type B hepatitis, auto-immune hepatitis or unknown, and 0 otherwise. In the validation group, according to the model-based risk of subsequent development of HE, sensitivity and specificity of the model were 100% and 69.0%, respectively, in patients with an evaluated risk lower than 20%, and 62.5% and 93.1%, respectively, in those with an evaluated risk equal to, or greater than, 50%. CONCLUSION In Japanese patients with symptomatic non-P ALD, our model, which includes four of the five items used in the King's College Hospital criteria, represents an acceptable, effective model to allow early detection of the risk of short-term development of HE. Using this model in other populations requires further validation specific to each of them.

Abstract
BACKGROUND/AIM The incidence of acute hepatitis B viral (HBV) infection in adults has increased in recent years in Serbia. Most icteric patients with acute hepatitis B resolve their infection and do not require treatment. Fulminant hepatitis B is a severe form of acute infection complicated by encephalopathy and liver failure. Subgroups of fulminant hepatitis B including hyperacute, acute and subacute are defined by the interval between jaundice and encephalopathy. Fulminant hepatic failure or subacute hepatitis B infection we observed in about 1% of all cases. In cases of fulminant hepatic failure or subacute form of HBV infection orthotopic liver transplantation can be life-saving operation, but in our country this procedure is difficult to achieve. Lamivudine has been established as a safe and effective antiviral agent for the treatment of chronic HBV hepatitis. METHODS In our pilot study performed at the Institute of Infectious and Tropical Diseases in Belgrade, Serbia in the period between 2002 and 2006 we treated 10 patients with clinically verified subacute HBV infection with lamivudine, 100 mg orally per day. RESULTS The most of the treated patients (9/10; 90%) survived subacute form of hepatitis B. After a few weeks of the treatment serum aminotransferase levels and other liver-function tests were normalized. Also, after a four-month lamivudine treatment all the patients lost HBsAg. Lamivudine was discontinued after six months in all the patients. In addition, six months after lamivudine was discontinued the patients remained well with normal results on liver-function tests. CONCLUSION The obtained results suggest significant efficacy of lamivudine in patients with subacute hepatitis B. Also, we suggest that lamivudine therapy should be administered early in progression of subacute disease since it could be life-saving treatment in some patients, especially in the countries (like Serbia) where orthotopic liver transplantation is difficult to achieve.

Abstract
UNLABELLED Pregnant patients with acute liver failure (ALF) are believed to have a worse outcome than nonpregnant women and men with ALF. However objective data supporting this supposition are scant. Therefore, the current study compared the outcome, complications, and causes of ALF among pregnant women and girls with age-matched nonpregnant women and girls and men and boys with ALF. One thousand fifteen consecutive ALF patients in the reproductive age group, admitted at the All India Institute of Medical Sciences, New Delhi, from January 1986 to December 2006, were included in the study. A total of 249 (38.5%) women were pregnant. They were compared with 341 nonpregnant women and girls and 425 men and boys, aged 15 to 45 years. The mortality rate of pregnant women and girls (53.8%) was similar to age-matched nonpregnant women and girls (57.2%), and men and boys (57.9%); P = 0.572. The clinical and biochemical features, disease severity, and complications were also similar in the three groups. A significantly higher proportion of ALF was attributable to hepatitis E virus (HEV) among women and girls who were pregnant (59.4%), as compared with both nonpregnant women and girls (30.4%), and men and boys (23.1%); P < 0.001. However, the outcome of HEV-related ALF was independent of the sex and pregnancy status of the patients (P = 0.103). Mortality in HEV-ALF and non-HEV-ALF patients in pregnant women and girls was 51% (74/145) and 54.7% (52/95)(P > 0.1), respectively. The outcome of pregnant ALF patients was also unrelated to the trimester of pregnancy. The mortality of non-HEV-related ALF among the pregnant women and girls (54.7%), age-matched nonpregnant women and girls (61.7%), and men and boys (62.8%) were also similar (P > 0.1). CONCLUSION The mortality of pregnant patients with ALF is similar to that of nonpregnant women and girls and men and boys and is independent of the cause or trimester. Pregnancy per se should not be regarded as a poor prognostic factor for a patient with ALF.

Abstract
BACKGROUND Drug-induced liver injury associated with antiepileptic drugs (AED) is well recognized. The frequency of the most common AED is rare but the consequences can be very serious leading to death or liver transplantation due to acute liver failure induced by these drugs. CLINICAL FEATURES Hypersensitivity features are found in more than 70% of patients with phenytoin-induced liver injury, whereas this is only observed in 30% of carbamazepine-associated hepatotoxicity and very rarely with valproate (VPA)-induced liver injury. PATHOPHYSIOLOGY The underlying mechanisms behind hepatotoxicity induced by AED are not clear. Reactive metabolites from AED can, in some cases, lead to direct cytotoxicity and liver cell necrosis, whereas in other cases this may lead to neoantigen formation inducing immunoallergic mechanisms. TREATMENT No specific therapy is of proved value in severe hepatotoxicity due to AED. However, N-acetylcystein is an appropriate treatment in patients with clinically significant liver injury due to phenytoin and carbamazepine. In patients with VPA-associated liver injury, carnitine that is an important co-factor in the mitochondrial beta-oxidation of fatty acids is the recommended treatment. Early referral of patients with severe liver reactions and coagulopathy to liver transplant centers before encephalopathy can be the difference between liver transplantation and death.

Abstract
The rapid aggravation of a patient affected by acute liver disease, including the occurrence of acute liver failure, a life-threatening complication, may be due in some cases to recently administered drugs or other xenibiotics. A previously healthy Indian man affected by acute hepatitis E developed acute liver failure after a 5-day treatment by herbal medicines. Pressure on health authorities and education of the general population should help to obviate such avoidable deaths. Physicians have the responsibility to convince their patients affected by acute liver disease not to take medicines for symptomatic relief, especially herbal medicines, up to recovery. The hypothesis is proposed that some of the fatal cases of acute hepatitis E in pregnant women, a common observation in India, could result from an earlier consumption of herbal medicines at the onset of the symptoms of acute hepatitis E.

Abstract
The cause of acute liver failure (ALF) is a major determinant of its outcome. Acetaminophen (paracetamol) overdose is a leading cause of ALF in some developed countries, whereas in others, such as Spain, it is extremely rare. To analyze the etiology, characteristics, and outcome of ALF in Spain, we performed a retrospective analysis of 267 patients whom we observed from 1992 to 2000. Seventeen tertiary-care hospitals with active liver transplantation (LT) programs contributed data. Causes of ALF were viral hepatitis in 98 (37%; hepatitis B virus in 75 patients), unknown in 86 (32%), drug or toxic reactions in 52 (19.5%; acetaminophen overdose in 6), and miscellaneous in 31 (11.6%). Overall survival was 58%. LT was performed in 150 patients, with a survival of 69%. Despite fulfilling criteria, 51 patients were not transplanted because of contraindications; their survival was only 7.8%. Forty-seven (85.5%) of 55 patients without transplant criteria survived. Hepatitis B virus is the most common cause of ALF in Spain, although the origin of 30% of cases remains undetermined. Acetaminophen overdose represents a very rare cause of ALF. LT was performed in >50% of cases. Patients without transplant criteria had a very good prognosis; those who fulfilled these criteria but who had contraindications for transplantation had a high mortality rate.

Abstract
UNLABELLED The Model for End-Stage Liver Disease (MELD) scoring system has been established as a reliable measure of short-term mortality risk in patients with end-stage chronic liver disease. The aim of this study was to evaluate the prognostic value of the MELD scoring as a predictor of fulminant hepatic failure (FHF) and death in patients with acetaminophen poisoning. Prospectively, serial measurements of the 3 MELD components--INR, bilirubin, and creatinine--were performed in 460 patients with acetaminophen-induced liver injury. Starting on the first day after the day of overdose, MELD score was significantly higher in patients who eventually developed hepatic encephalopathy (HE) than in those who did not. HE developed in 63 of 142 patients with a MELD score above 18 at 48-72 hours after the overdose (positive predictive value 44%) compared with 2 of 182 patients with a MELD score of 18 or below (negative predictive value 99%). Among 124 patients with FHF, a threshold MELD score of 33 on the day after the onset of HE had sensitivity of 60%, specificity of 69%, positive predictive value of 65%, and negative predictive value of 63%. However, the discriminative power of MELD score was not superior to that of INR alone or of the King's College Hospital criteria. CONCLUSION MELD score may be useful as a predictor of FHF in patients admitted with acetaminophen toxicity. However, as a predictor of death from FHF, MELD score did not provide more information than the King's College Hospital criteria or INR alone.

Abstract
A 65-year-old Japanese man was hospitalized because of acute hepatitis and severe cholestasis due to hepatitis E virus (HEV) infection combined with a drug reaction to a cold preparation. He died of disseminated intravascular coagulation and severe intestinal bleeding due to systemic cytomegalovirus reactivation following the development of severe eruptions with marked eosinophilia due to drug hypersensitivity to taurine and ursodeoxycholate preparations. The close interaction between viral infection or reactivation and drug hypersensitivity was considered as a pathophysiology in this case, which emphasizes the need for further study of the immunological mechanism of the interaction.
