Abstract
BACKGROUND & AIMS Acute liver failure patients who meet poor prognostic criteria have high early mortality without emergency liver transplantation. A recent study however, reported that patients that survive spontaneously have a poorer outcome compared with patients undergoing transplantation. In this single centre study, we aimed to confirm or refute this observation. METHODS Early survivors (acute liver failure patients who survived 90 days after the ICU admission) were assessed for long-term outcomes in four distinctive cohorts, incorporating aetiology (Acetaminophen overdose or non-Acetaminophen overdose), and management strategy (conservative or liver transplantation). Chi Squared or Fisher test were used to compare outcomes among the four cohorts (P < 0.05) and Kaplan-Meier curve (Log Rank test) to represent cumulative survival. RESULTS Two hundred consecutive acute liver failure patients between 1990 and 2014 were included; mean age 38.3, ±12.8, male 70, 35%. 124/200 (62%) early survivors were identified; 13/124 (10.5%) acetaminophen patients underwent transplantation and 48/124 (38.7%) survived spontaneously; 36/124 (29.0%) non-acetaminophen underwent transplantation and 27/124 (21.8%) survived spontaneously. A total of 11/124 (8.9%) died subsequently (median survival 5.3± IQR 9.1), three spontaneous survivors and eight transplanted patients (P = 0.025); of the eight transplanted patients, six died of transplant related complications and two of suicide. CONCLUSION The results of this study suggest that although liver transplantation is a life-saving procedure for acute liver failure patients, they have a worse long-term outcome compared with spontaneous survivors. Novel therapies to increase the percentage of spontaneous survivors are urgently needed.

Abstract
The case for using emergency liver transplantation in acute liver failure was made two decades ago by a series of single centre experiences. The development of models identifying a poor prognosis assisted the selection of patients for liver transplantation but none of these delivers both high sensitivity and specificity for prediction of death. Enhanced sensitivity favours the individual patient while enhanced specificity targets the pool of organs available at those who will derive greatest benefit. The non-transplant survival rates have improved considerably for certain cohorts of patients and these prognostic models have not been adjusted to reflect these changes. The presumption of transplant benefit can no longer be taken as established in paracetamol-related acute liver failure and a policy review is appropriate. In other scenarios, such as seronegative hepatitis and the phenotype of sub-acute liver failure, spontaneous survival rates remain low and the basis for liver transplantation remains sound. Outcomes after liver transplantation are improving but are not yet comparable to elective transplantation. The understanding of factors associated with failure after liver transplantation is improving but accurate definition of futility has not yet been attained.

Abstract
Liver transplantation is now an integral part of the management of acute liver failure. The challenge for clinicians is to select the appropriate candidates with a combination of need and high likelihood of benefiting from the transplant. This is achieved through a combination of prognostic modelling and ongoing clinical evaluation. Although the outcomes after liver transplantation are good the survival rates do not quite match those achieved after elective transplantation.

Abstract
BACKGROUND Fulminant hepatic failure (FHF) is a rare condition. Several series have been reported either by individual centres or in multicentre studies but, to our knowledge, this is the first report from a Portuguese population and might be a good example of FHF cases in a SouthWestern European population. AIMS To present the experience in FHF of a Portuguese Hepatogastroenterological Intensive Care Unit. MATERIALS AND METHODS Retrospective study of 61 cases of FHF consecutively admitted between February 1992 and October 2006. Definition and classification of FHF were those suggested by Trey and Davidson (1970) and O'Grady et al. (1993), respectively. Criteria and contraindications for hepatic transplantation (HT) were those proposed by Bernuau et al. (1991) and Muñoz (1993), respectively. RESULTS Fifty-seven per cent of patients were women and median age was 37 years (range: 8-73). Most common cause of FHF was indeterminate (26%) followed by viral (23%) and drug-induced (23%), with 51% of cases with a hyperacute evolution. Global HT rate was 54% with criteria for HT present in 87% of the patients resulting in an applicability rate of 62%. Overall survival was 69% and transplant-free survival was 15%; transplanted patients had survival rates of 70 and 68% at 6 and 12 months, respectively. CONCLUSIONS Drug-induced and viral agents were responsible for almost half of FHF cases with a clear predominance of hyperacute presentation. The HT rate was 54% and the applicability rate was 62%. The overall 1 year survival of 69% might reflect the adequacy of the HT criteria used.

Abstract
BACKGROUND/AIMS Acute liver failure (ALF) in children has been associated with an overall mortality of approximately 70% in the pretransplant era and 50-80% survival in those undergoing orthotopic liver transplantation. There is currently no system for staging severity of ALF in children. The aim of this study was to characterize pediatric ALF in a tertiary hospital and to derive a scoring system to stratify severity of ALF based on predicted mortality. METHODS Prospective data collection of 81 children from December 1993-2003 who presented with ALF. Data recorded included peak laboratory values, clinical characteristics, and survival. RESULTS Transplant-free survival was 56% with overall survival including those undergoing OLT of 72%. Transplantation rate was 22% with transplant survival of 72%. Of the peak laboratory values analyzed, total bilirubin, prothrombin time/INR, and ammonia were the most predictive of death or a need for liver transplant. A simple risk staging system was developed based on the ability of these three laboratory measurements to predict mortality. CONCLUSIONS The survival in pediatric ALF has improved in recent years. Risk staging for ALF could potentially be used in clinical research for risk-adjusted outcomes analysis and to help stratify patients for clinical studies according to mortality risk.

Abstract
Severe acetaminophen hepatotoxicity frequently leads to acute liver failure (ALF). We determined the incidence, risk factors, and outcomes of acetaminophen-induced ALF at 22 tertiary care centers in the United States. Detailed prospective data were gathered on 662 consecutive patients over a 6-year period fulfilling standard criteria for ALF (coagulopathy and encephalopathy), from which 275 (42%) were determined to result from acetaminophen liver injury. The annual percentage of acetaminophen-related ALF rose during the study from 28% in 1998 to 51% in 2003. Median dose ingested was 24 g (equivalent to 48 extra-strength tablets). Unintentional overdoses accounted for 131 (48%) cases, intentional (suicide attempts) 122 (44%), and 22 (8%) were of unknown intent. In the unintentional group, 38% took two or more acetaminophen preparations simultaneously, and 63% used narcotic-containing compounds. Eighty-one percent of unintentional patients reported taking acetaminophen and/or other analgesics for acute or chronic pain syndromes. Overall, 178 subjects (65%) survived, 74 (27%) died without transplantation, and 23 subjects (8%) underwent liver transplantation; 71% were alive at 3 weeks. Transplant-free survival rate and rate of liver transplantation were similar between intentional and unintentional groups. In conclusion, acetaminophen hepatotoxicity far exceeds other causes of acute liver failure in the United States. Susceptible patients have concomitant depression, chronic pain, alcohol or narcotic use, and/or take several preparations simultaneously. Education of patients, physicians, and pharmacies to limit high-risk use settings is recommended.

Abstract
OBJECTIVE To review the outcome of acute liver failure (ALF) and the effect of liver transplantation in children in Australia. METHODOLOGY A retrospective review was conducted of all paediatric patients referred with acute liver failure between 1985 and 2000 to the Queensland Liver Transplant Service, a paediatric liver transplant centre based at the Royal Children's Hospital, Brisbane, that is one of three paediatric transplant centres in Australia. RESULTS Twenty-six patients were referred with ALF. Four patients did not require transplantation and recovered with medical therapy while two were excluded because of irreversible neurological changes and died. Of the 20 patients considered for transplant, three refused for social and/or religious reasons, with 17 patients listed for transplantation. One patient recovered spontaneously and one died before receiving a transplant. There were 15 transplants of which 40% (6/15) were < 2 years old. Sixty-seven per cent (10/15) survived > 1 month after transplantation. Forty per cent (6/15) survived more than 6 months after transplant. There were only four long-term survivors after transplant for ALF (27%). Overall, 27% (6/22) of patients referred with ALF survived. Of the 16 patients that died, 44% (7/16) were from neurological causes. Most of these were from cerebral oedema but two patients transplanted for valproate hepatotoxicity died from neurological disease despite good graft function. CONCLUSIONS Irreversible neurological disease remains a major cause of death in children with ALF. We recommend better patient selection and early referral and transfer to a transplant centre before onset of irreversible neurological disease to optimize outcome of children transplanted for ALF.

Abstract
The systemic inflammatory response syndrome (SIRS) in acute liver failure (ALF), in which infection is common, has not been studied. In this study, SIRS components were recorded on admission and during episodes of infection, in 887 ALF patients admitted to a single center during an 11-year period. Overall, 504 (56.8%) patients manifested a SIRS during their illness, with a maximum of 1, 2, and 3 concurrent SIRS components in 166, 238, and 100 patients, respectively. In 353 (39.8%) patients who did not become infected, a SIRS on admission was associated with a more critical illness, subsequent worsening of encephalopathy, and death. Infected patients more often developed a SIRS and one of greater magnitude. The magnitude of the SIRS in 273 patients with bacterial infection correlated with mortality, being 16.7%, 28.4%, 41.2%, and 64.7% in patients with 0, 1, 2, and 3 maximum concurrent SIRS components, respectively. Similar correlations with mortality were seen for SIRS associated with fungal infection, bacteremia, and bacterial chest infection. Fifty-nine percent of patients with severe sepsis died, as did 98% of those with septic shock. A significant association was found between progressive encephalopathy and infection. Infected patients with progressive encephalopathy manifested more SIRS components than other infected patients. For patients with a SIRS, the proportions of infected and noninfected patients manifesting worsening encephalopathy were similar. In ALF, the SIRS, whether or not precipitated by infection, appears to be implicated in the progression of encephalopathy, reducing the chances of transplantation and conferring a poorer prognosis.

Abstract
Mortality is high in patients with fulminant hepatic failure (FHF). Neurologic complications of encephalopathy and cerebral edema are major contributors to mortality. Orthotopic liver transplantation has improved survival in these patients. However, the complexity of medical and surgical problems in this patient population, coupled with a severe shortage of organs, requires careful patient selection. The aim of this study was to describe the neurologic outcome of children with FHF who developed radiologically apparent cerebral edema. The hospital and outpatient records and radiologic studies of 20 children with FHF admitted to Children's Hospital of Pittsburgh from 1981-1995 who developed encephalopathy and computed tomographic evidence of cerebral edema were reviewed. Fourteen patients died (70%), three were left with severe neurologic deficits (15%), and three were left with moderate deficits (15%). Survival was correlated with a lesser degree of coma. Histopathologic examination of eight brains demonstrated cerebral edema and widespread ischemic neuronal necrosis in all eight. The presence of radiographic cerebral edema in children with FHF is an objective measure that indicates a very poor prognosis. Termination of care is a reasonable option. Comprehensive monitoring of cerebral function and intracranial pressure is required in children with FHF. Orthotopic liver transplantation should be performed in children with severe and worsening encephalopathy before the development of radiographically apparent cerebral edema.

Abstract
Fulminant hepatic failure is a devastating illness that carries considerable mortality and affects patients with previously healthy livers. Although the etiology of FHF remains unclear in a significant number of cases, viral hepatitis and drug-induced liver injury account for the majority of identifiable causes. The clinical presentation varies widely, but is always characterized by the presence of encephalopathy. Markedly elevated transaminases are seen, but do not correlate with extent of liver injury. Prothrombin time, bilirubin, creatinine, and arterial pH are prognostic indicators of survival in FHF. FHF and its consequences must be readily recognized so that appropriate triage and treatment can be administered. All patients should be managed in an intensive care setting pending transfer to a liver transplantation center. Supportive care remains the mainstay of treatment, with liver transplantation reserved for select patients.

Abstract
Fulminant hepatic failure is associated with high mortality. Liver transplantation is an effective therapy that improves survival, and because of donor organ shortage and urgency, a bioartificial liver could act as an effective bridge to liver transplantation in patients with fulminant hepatic failure. We discuss the place of the bioartificial liver in the treatment of other causes of liver failure.

Abstract
BACKGROUND Liver transplantation is the therapeutic choice for fulminant hepatic failure in children. METHODS All 66 cases of fulminant hepatic failure in the pediatric population seen at UCLA from May, 1985 to November, 1993 were reviewed to determine changes in survival rates since the advent of liver transplantation. We evaluated the clinical course and events leading to the exclusion of surgical management of nonsurvivors, who otherwise would have benefited from a liver transplant. We also compared the latter's clinical course with the nontransplant survivors to determine parameters for screening patients for liver transplantation. RESULTS Fifty-one patient (77%) were put on the transplant list initially but eventually, only 38 (58%) patients underwent orthotopic liver transplantation (OLT) and of these 30 (79%) patients survived. Of the remaining 29 (42%) patients who did not undergo liver transplantation, only 10 (36%) patients survived. Nine patients died while waiting for a donor liver secondary to complications of hepatic failure. The majority of nonsurvivors in the OLT and no-OLT groups succumbed because of irreversible neurologic deterioration. In the no-OLT group, comparisons between survivors and non-survivors were made. There were no significant demographic differences. It took a mean of 8 days (+/-8) versus 22 days (+/-15), (p = 0.009), from onset of illness to first hospital admission for survivors and nonsurvivors, respectively. Time to reach stage II encephalopathy was a mean of 5 days (+/-5) for survivors versus 18 days (+/-16), (p = 0.05) for nonsurvivors. Nonsurvivors were transferred to the transplant center at a mean of 12.2 days (+/-12) after being first admitted elsewhere as compared to a mean of 1.9 days (+/-18) for survivors, (p = 0.02). Mean prothrombin time decreased by a mean of 13.4 s/day (+/-16) for survivors as against 2.25 s/day (+/-6) for nonsurvivors, (p = 0.06). Mean peak total bilirubin for nonsurvivors was 460 mumol/L (27 mg/dl) versus 220 mumol/L (13 mg/dl) for survivors, (p = 0.06). Nonsurvivors died at a mean of 30 days (+/-19) from onset and survivors' liver tests started to improve at a mean of 11 days (+/-9) from onset. CONCLUSIONS From these studies, we conclude that liver transplantation remains the therapeutic choice for fulminant hepatic failure in children. Early referral and closer follow-up is necessary for timely admission to liver transplant centers to enable screening and proper preparation of these patients for liver transplantation.

Abstract
Acute liver failure (ALF) remains a major cause of morbidity and mortality. Before the availability of liver transplantation only 20% of patients with ALF survived. The clinical dilemma relates to the prognostication of these patients, as early liver transplantation has been associated with better outcomes. The eligibility for liver transplantation must therefore be quickly established. The patient's age, aetiology of disease, interval between the onset of jaundice and encephalopathy, blood pH, prothrombin time, serum bilirubin and serum creatinine levels has been identified as useful prognostic markers. The degree of hepatocyte necrosis on liver biopsy and estimated hepatic volume by computed tomography may also be valuable predictors of survival; however, further studies are needed.

Abstract
Fulminant hepatic failure (FHF) in the absence of serum markers of hepatitis A (HAV) or B (HBV) infection or another cause is called non-A, non-B (NANB) FHF. The pathogenetic role of viral infection in NANB FHF remains controversial. To better define this relationship, we studied patients who underwent orthotopic liver transplantation (OLT) for FHF. Thirty-six patients with FHF underwent transplantation between 1987 and 1992. Pre-OLT serum was available for 24 patients, 14 with NANB FHF (all female; mean age, 32 years), and 10 (3 males, 7 females; mean age, 20 years) with a defined origin for FHF who formed the control group. Sera were tested using polymerase chain reaction for HAV, HCV, HDV, and HEV RNA and HBV DNA, and also serologically for antibodies to these viruses. In the NANB group, pre-OLT serum was negative for all viruses tested. Four patients in the control group had HBV serologically, 2 with HBV DNA in serum. One of these 4 also had hepatitis C and one hepatitis D infection. There was no difference in intensive care unit or hospital stay between the groups. The only significant difference in laboratory data was for peak creatinine pre-OLT (0.94 mg/dL in NANB v 1.62 mg/dL; P < .05). Two patients in the NANB groups and 3 in the control group required early retransplantation for graft primary nonfunction. One case of NANB FHF appeared to recur at 6 months but not after subsequent retransplantation. NANB FHF is not associated with hepatitis A, B, C, D, or E in plasma. It has a later age of onset but a similar clinical course to other forms of FHF and appears to preferentially affect women.

In this cohort we examined the impact of pretransplant renal failure on mortality and morbidity following orthotopic liver transplantation (OLTx). Twenty-seven patients (18 female, 9 male) with a median age of 43.5 years (range 19-65 years) underwent OLTx. FHF was due to idiosyncratic drug reaction (n = 4), paracetamol overdose (n = 3), seronegative hepatitis (n = 17), hepatitis B (n = 1), veno-occlusive disease (n = 1), and Wilson's disease (n = 1). Renal failure was present in 14 patients, 7 of whom died (whereas there was 100% survival in patients without renal failure). Pretransplant renal failure was associated with prolonged mechanical ventilation (13 days vs 6 days, P = 0.05), prolonged intensive care stay (17 days vs 8 days, P = 0.01) and prolonged hospital stay (27 vs 21 days, P = NS). Pretransplant renal failure did not predict renal dysfunction at 1 year after OLTx. We conclude that the survival of patients transplanted for FHF is inferior to that of patients transplanted for chronic liver disease (67% vs 88% 1-year survival in Birmingham). For patients with FHF undergoing transplantation, pretransplant renal failure strongly predicts poor outcome with significantly greater consumption of resources.

Abstract
OBJECTIVE The authors report on the experience of orthotopic liver transplantation in fulminant hepatitis at Paul Brousse Hospital. SUMMARY BACKGROUND DATA Liver transplantation is a breakthrough in the treatment of patients with fulminant hepatitis. However, the indications, the timing for transplantation, the type of transplantation, and the use of ABO incompatible grafts in this setting still are debated. METHODS Transplantation was indicated in patients with confusion or coma and factor V less than 20%, younger than 30 years of age, and confusion or coma and factor V less than 30% older than 30 years of age. RESULTS Among 139 patients who met the aforementioned criteria for transplantation, 1 recovered, 22 died before transplantation, and 116 underwent transplants with a 1-year survival of 68%. Survival was 83% in patients with grade 1 and 2 comas at transplantation versus 56% (p < 0.001) in those with grade 3 comas; it was 51% versus 81% (p < 0.001) in those transplanted with high risk (ABO-incompatible, split, or steatotic) and low-risk grafts, respectively. In a multivariate analysis, steatotic and partial grafts were predictive of poorer patient survival, and ABO incompatibility was predictive of poorer graft survival. CONCLUSIONS Orthotopic liver transplantation is an effective treatment in fulminant hepatitis. Use of high-risk grafts permitted transplantation of 83% of patients, but was responsible for higher mortality.

Abstract
This investigation summarizes and evaluates the results of a clinical protocol that we designed to care for patients with acute liver failure (ALF). Adult patients with ALF were enrolled in the protocol. Grade II portal-systemic encephalopathy prompted admission to the intensive care unit (ICU). Patients who met the clinical criterion were activated for liver transplantation. Intracranial pressure (ICP) was monitored in patients with grade III encephalopathy. An increase in ICP was treated with hyperventilation, diuretics, barbiturates, or a combination thereof. Survival was considered to have occurred if the patient left the hospital alive. Our series included 25 patients. Orthotopic liver transplantation (OLT) was performed on 19 patients, 12 of whom survived. Only 2 of 6 patients who did not undergo transplantation survived. Ten of 11 patients who underwent transplantation before reaching grade IV encephalopathy survived. Only 2 of 8 patients who underwent transplantation after reaching grade IV survived (P = .006). The causes of death included cerebral edema (3 patients), disseminated aspergillosis (3 patients), and other (5 patients). ICP was monitored in 11 patients. Increased pressure was documented by seven of the monitors placed. There was one focal hemorrhage secondary to a subdural monitor. Outcome is improved if transplantation occurs before grade IV encephalopathy. ICP monitoring can be accomplished without significant risk of hemorrhage. In our series, infection with aspergillus occurred frequently and with fatal outcome.

Abstract
OBJECTIVE To describe a series of consecutive patients with fulminant hepatic failure (FHF) and to present a new classification system for brain edema, an important cause of mortality in such patients. DESIGN We reviewed 22 computed tomographic (CT) scans of the brain in 12 patients with FHF and classified the severity of cerebral edema by using predefined criteria. RESULTS No cerebral edema was detected on CT scans in four patients with stage 1 or 2 hepatic encephalopathy at the time of admission, but it was noted in seven of eight patients with stage 3 or 4 hepatic encephalopathy. The severity of brain edema on CT scans was significantly correlated (P < 0.001) with the stage of hepatic encephalopathy. Three of the four patients who had stage 1 or 2 hepatic encephalopathy at the time of initial assessment ultimately had a good outcome. Of seven patients with stage 3 encephalopathy, two had rapid deterioration to brain death, three died of nonneurologic causes, and two had a good outcome after liver transplantation. One patient with stage 4 hepatic encephalopathy died, and autopsy showed cerebral edema. CONCLUSION Stage 3 or 4 hepatic encephalopathy is associated with cerebral edema that can be detected on CT scans. The clinical and radiologic signs of cerebral edema in patients who have progression to stage 3 hepatic encephalopathy can be reversed with conventional treatment of increased intracranial pressure. Whether early recognition and treatment of cerebral edema result in increased survival of patients with FHF remains to be determined.

Abstract
Cerebral edema and intracranial hypertension, commonly present in fulminant hepatic failure, may lead to brainstem herniation and limit the survival of comatose patients awaiting liver transplantation before a donor organ becomes available. Also, they are likely responsible for postoperative neurological morbidity and mortality. Although intracranial pressure monitoring has been proposed to aid clinical decision making in this setting, its use in the prevention of brainstem herniation preoperatively, in the selection of patients for liver transplantation who have the potential for neurological recovery and in the maintenance of cerebral perfusion during liver transplantation has not been examined in detail. To address these issues, we established a protocol for intracranial pressure monitoring in comatose patients with fulminant hepatic failure as part of their preoperative and intraoperative management. Twenty adults and three children underwent intracranial pressure monitoring. Ten patients required preoperative medical therapy with mannitol, barbiturates or both for a rise in intracranial pressure above 25 mm Hg. Four patients had a sustained lowering of intracranial pressure, three of whom survived hospitalization. Six patients had intracranial hypertension refractory to medical management, were removed from a waiting list for a donor organ and died with brainstem herniation. Of the remaining 17 patients, 3 died of other causes while awaiting a donor organ, 2 recovered spontaneously without neurological sequelae and 12 underwent liver transplantation. All but one patient undergoing liver transplantation had transient intraoperative intracranial hypertension develop, requiring medical treatment. The 12 patients who had transplants recovered neurologically and were discharged from the hospital.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Neuropathologic findings are described in 37 patients autopsied after one or more orthotopic liver transplants. Gross or microscopic lesions were observed in almost all patients, including anoxic-ischemic change, hemorrhages and/or infarcts, and opportunistic infections by fungi (most commonly Aspergillus) and rarely viruses (cytomegalovirus). Central pontine and extra-pontine myelinolysis was commonly observed, and appeared to result from severe multifactorial metabolic abnormalities in the perioperative period. Low-grade (microglial nodule) encephalitis without an obvious pathogen was often encountered. Common clinical neurologic abnormalities included encephalopathy, seizures (myoclonic, focal or generalized), obtundation and coma. These were found more commonly than focal findings, but clinical features in a given patient were not uniformly predictive of underlying neuropathologic change.

Abstract
The Acute Hepatic Failure Study Group (AHFSG) has conducted a double-blinded, randomized evaluation of hydrocortisone in patients with acute hepatic failure. From July 1975 through August 1978, a 38-month period, 18 medical centers in the United States and one in Canada participated in this trial. A total of 64 patients were accessed and found eligible to participate in the study; two of them were subsequently eliminated from our analysis. Eighteen patients received placebo; 23 received 400 mg hydrocortisone per day, and 21 patients were administered 800 mg hydrocortisone per day. We did not observe any therapeutic effect of hydrocortisone, and the survival rates for placebo versus 400 mg and versus 800 mg hydrocortisone per day were 22%, 9%, and 24%, respectively. Fulminant hepatitis associated with drug hepatotoxicity or non-A, non-B hepatitis seemed to have a worse prognosis than fulminant B, although these differences were not significant. Serum alpha-fetoprotein had a modest prognostic value of survival and seemed to be limited to fulminant B. The AHFSG recommends, therefore, that corticosteroid use in acute hepatic failure with hepatic encephalopathy be discontinued.

Abstract
Amanita phalloides mushroom poisoning is an increasingly common and potentially lethal problem for which liver transplantation offers definitive therapy in selected patients. When significant liver dysfunction appears, early transfer to a liver transplant center is important to identify appropriate candidates and to begin the search for a donor organ. The clinical course of five severely poisoned patients, four of whom underwent liver transplantation, is reviewed. Indications for transplantation included primarily a markedly prolonged prothrombin time that was only partially correctable and a constellation of findings including metabolic acidosis, hypoglycemia, hypofibrinogenemia, and increased serum ammonia, following a marked elevation in serum aminotransferase levels. Unlike viral fulminant hepatic failure, grade III or IV hepatic encephalopathy, marked elevation of the serum bilirubin level, and azotemia were not indications for transplantation. Resected livers demonstrated hepatocyte viability of 0% to 30%. Manifestations of Amanita poisoning complicating preoperative and/or postoperative care included severe diarrhea, gastrointestinal hemorrhage, hypophosphatemia, bowel edema, and marrow suppression with lymphopenia, thrombocytopenia, and neutropenia. All five patients are well 1 year later. This largest experience with liver transplantation for Amanita poisoning further defines the early clinical and laboratory indications for, and the unique complicating features of, transplantation in this setting.
