Abstract
Wilson disease is an inherited, autosomal recessive, copper accumulation and toxicity disorder that affects about 30 individuals per million. This rare disease is caused by mutations in the gene encoding a copper-transporting P-type ATPase, which is important for copper excretion into bile, leading to copper accumulation in the liver. Toxic copper concentrations can also be found in the brain and kidney, and clinical phenotypes include hepatic, haemolytic, neurologic and psychiatric diseases. Diagnosis is based on the combination of clinical features and findings such as increased urinary copper excretion, reduced levels of serum ceruloplasmin, high concentrations of copper in liver tissues and Kayser-Fleischer rings. Genetic studies are also becoming available for clinical use, but the utility of direct mutation analysis is limited. Wilson disease can be treated, and early diagnosis is essential: the goal of therapy is to reduce copper accumulation either by enhancing its urinary excretion or by decreasing its intestinal absorption. Medical therapies include penicillamine, trientine, zinc and tetrathiomolibdate. Liver transplantation is a relatively successful treatment option when medical therapy fails or in case of acute liver failure, even though it is also characterized by short- and long-term complications.

Abstract
Wilson's disease is a rare metabolic disorder that may lead to fulminant hepatitis and subsequent liver failure. Herein, we present a case of split liver transplantation performed on a patient with acute Wilson's disease. A 27-year-old female with acute presentation of Wilson's disease and advanced neurological impairment, received a Right Split liver Graft (Segments: IV, V, VI, VII and VIII) transplant. The graft was obtained by an in situ splitting technique. The graft implantation was performed in a standard fashion. No acute rejection episodes of the organ occurred. The postoperative course was uneventful. The graft function, ceruloplasmine level and copper levels progressively normalized. The patient totally recovered from neurological symptoms and the Kayser-Fleischer rings disappeared within one month. At 13 months of follow-up, the patient presented with no symptoms and in good condition. The current literature reports high preoperative mortality rate in patients that underwent partial liver graft for acute hepatic failure. However, our experience indicates that in situ split technique of liver may be a feasible and effective alternative to whole graft transplantation in urgent cases. Moreover, to our knowledge, this is the first successfully case of in situ split liver transplantation for acute Wilson's disease described in literature.

Abstract
Liver transplantation has become an accepted treatment for several metabolic liver diseases. With advances in organ transplantation and immunosuppressive strategies, survival rates following liver transplantation are generally excellent. When the primary metabolic defect is hepatic in origin, liver transplantation not only replaces the dysfunctional organ but also cures the underlying metabolic defect. For conditions in which the primary metabolic defect is extrahepatic, liver transplantation is usually performed for hepatic complications, although disease recurrence may occur. This article reviews common metabolic liver diseases treated with liver transplantation in the adult population.

Abstract
Neurologic complications (NCs) are a significant cause of morbidity and mortality in patients who undergo liver transplantation (LT). The aim of this study was to evaluate the incidence and type of NCs and associated factors in pediatric LT patients. We retrospectively reviewed NCs in the medical records of 40 consecutive infants, children, and adolescents who underwent LT at our institution. The subjects consisted of 23 boys and 17 girls (median age, 8.5 +/- 0.85 yr; range, 11 months to 17 yr). The indications for LT were Wilson's disease in 10 patients, fulminant hepatic failure (FHF) in nine, and other types of chronic liver disease in 21. NCs were found in 14 patients (35%). Those 14 individuals experienced a total of 16 episodes of NCs (two separate episodes in two of the patients). The most common NCs were seizure (seven episodes in six patients) and posterior leukoencephalopathy syndrome (PLES; five episodes in four patients). Seizure was the presenting symptom in three episodes of PLES. Two episodes of diffuse encephalopathy were observed in two patients, and two episodes of psychiatric symptoms occurred in two patients. We also noted one episode of tremor in one patient, one episode of acute dystonic reaction in one patient, and one episode of headache in one patient. Patients with Wilson's disease had a higher incidence of NCs (60%) than did patients without Wilson's disease (26.7%); however, this difference was not significant. The incidence of NCs was 44% in patients with FHF and 35% in those without FHF. That difference also was not significant. Immunosuppressive agents were the primary cause of 13 of the 16 episodes of NC. Uremia with hypertension, hypoxia, and hypomagnesemia caused one neurologic episode each. NCs, which are frequent in the first 30 days after pediatric LT, did not affect survival in this group. NCs were reversed by the discontinuation or reduction of immunosuppressive agents in 12 episodes, correction of hypomagnesemia and the reduction of immunosuppressive agents in one episode, and the correction of uremia and hypertension in one episode. Refractory epilepsy developed in one patient, and death unrelated to NCs occurred in one. The mortality rate was 7.1% (n = 1) in patients with NCs and 15.4% (n = 4) in those without NCs (p = 0.64). NCs are an important complication after LT. It is essential that each transplantation team collaborate with pediatric neurologists to ensure the rapid and accurate diagnosis of NCs in infants, children, and adolescents after LT and to prevent the delay of appropriate treatment.

Abstract
We described six children with heritable liver disease and hepatocellular carcinoma treated with living-related liver transplantation. Underlying liver diseases were type-1 tyrosinemia (three patients), progressive familial intrahepatic cholestasis type II (two patients), and Wilson's disease (one patient). Two of the tumors were found incidentally during liver transplantation. Number of nodules was 12, 15, 3, 2, and 1 (in two patients). Three patients were treated with chemotherapy before the procedure. Chemotherapy was not given to any patient after liver transplantation. The mean follow-up was 17.7 +/- 6 months (range: 7-24). All patients are tumor recurrence free. Both graft and patient survival rates are 100% at a median of 18.5 months follow-up. Physicians in charge of treating children with heritable liver disease should screen them periodically for the development of hepatocellular carcinoma. Liver transplantation may offer these children better survival rates.

Abstract
Fulminant Wilson's disease (WD) is almost invariably fatal, and liver transplantation is the only life-saving treatment. Decompensated chronic WD usually responds to chelation therapy. Our aim was to validate 3 published scoring systems for deciding between chelation treatment and liver transplantation in patients with chronic decompensated and fulminant WD. Model for end-stage liver disease (MELD) score, as well as WD prognostic index (WPI) and its recently revised version (RWPI) were evaluated as predictors of the safety for chelation therapy. A group of 14 adult patients with decompensated chronic WD who improved on penicillamine treatment were compared with 21 patients with fulminant WD. The diagnosis of WD was based on increased urinary copper excretion and confirmed by elevated liver copper content and/or mutation analysis of the WD gene. The MELD score, WPI, and RWPI were calculated for all patients with WD. The accuracy of the MELD score, WPI, and RWPI for prediction of response to chelation therapy in patients with decompensated chronic WD was 0.968, 0.980, and 0.993, respectively. None of the decompensated chronic WD patients had a MELD score >30, RWPI >11, or WPI >7. RWPI showed the highest accuracy and the lowest false negativity compared with WPI and MELD. In conclusion, our data indicate that RWPI, originally proposed for pediatric patients, is also useful for adults.

Abstract
OBJECTIVE To summarize the experience in donor selection and surgical outcomes of living related liver transplantation (LRLT) for Wilson's disease (WD). METHODS Thirty-two WD patients, 29 children and 3 being over 14, underwent LRLT because of chronic advanced liver disease (29 cases) or fulminant hepatic failure (3 cases) among which 13 cases showed neurological dysfunction. The donors, including 7 fathers and 25 mothers, had their serum ceruloplasmin levels within normal limit or slightly lower and their 24-hour urine copper < 100 microg. The modes of operation included orthotopic partial liver transplantation (31 cases) and orthotopic accessory partial liver transplantation (1 case). The patients were followed p for 3-63 months postoperatively. RESULTS Two patients die in the intraoperative period, and 2 died of bile leakage and severe rejection combined with infection. Twenty-eight patients survived, of which 2 had hepatic artery thrombosis and underwent retransplantation of cadaveric liver, one had anatomic stenosis 8 months after the original transplantation and underwent Roux-en-Y hepaticojejunostomy, 2 had chronic rejection 22 and 28 months after the LRLT respectively and were successfully rescued by switching their primary immunosuppressor from cyclosporine A to FK506. Eleven patients with neurological dysfunctions all showed long-term survival and their extrapyramidal signs and speech disorders, and dyskinesia all were alleviated. CONCLUSION LRLT is the treatment of choice for WD patients with chronic advanced liver disease and fulminant hepatic failure. After LRLT the disorders of the nervous system are alleviated.

Abstract
Wilson's disease is a hereditary disorder of copper metabolism that results in the accumulation of copper in the body, primarily in the liver, brain, and cornea. Hepatocellular carcinoma, in contrast to other causes of cirrhosis, is seldom associated with Wilson's disease. We present a 12-yr-old boy with Wilson's disease in whom hepatocellular carcinoma was incidentally diagnosed in the pathologic specimen examined after liver transplantation.

Abstract
Among 71 patients, 19 (26.7%) experienced tacrolimus-related complications including 15 neurologic reactions and four problems with nephrotoxicity. Seven of these patients received grafts from cadaveric donors and 12 from living donors. Nine patients were children. The cohort included 5 female and 14 male subjects of mean age 26 +/- 20 (min 6, max 65) years. The common indications for the liver transplantation were cholestatic and metabolic diseases in pediatric patients, and viral hepatitis in adult patients. Blood tacrolimus levels were within the normal range. All patients with neurologic complications received antiepileptic therapy and drug conversion to rapamycin in 4 cases and to cyclosporine (CsA) in 11 cases. Six cases with Wilson disease and all cases with tyrosinemia experienced neurologic complications, which reversed in all but one case. In four cases with nephrotoxicity, we switched to rapamycin. Renal function improved in all cases. Patients with Wilson disease and tyrosinemia were more susceptible to the neurologic side effects of tacrolimus. In these cases we recommend the use of drugs with fewer neurologic side effects. Tacrolimus also has nephrotoxic effects, which can be reversed by converting to rapamycin.

Abstract
Acquired (non-Wilsonian) hepatocerebral degeneration (AHD) is a chronic brain disorder caused by liver dysfunction and long-standing portal-systemic shunting. It typically presents with dysathria, ataxia, tremor, involuntary movements and altered mental status, and often does not respond to conventional medical therapy for hepatic encephalopathy. There is scarce and conflicting information regarding the clinical course of AHD after liver transplantation (OLT). We present a case of a 47-year-old woman with hepatitis C (HCV) cirrhosis who developed severe manifestations of AHD after multiple bouts of hepatic encephalopathy. Her first OLT was complicated with primary nonfunction requiring immediate retransplantation. The second OLT led to complete clinical and radiological resolution of the AHD. However the patient developed recurrence of AHD 11 months post-transplant due to recurrent HCV and chronic rejection leading to cirrhosis of the graft. The patient developed severe neurological symptoms, despite mild synthetic graft dysfunction. A third OLT led again to disappearance of the clinical and radiological manifestations of AHD. AHD may show complete resolution after OLT; however it may rapidly recur following recurrent liver disease or graft dysfunction.

Abstract
OBJECTIVE To summarize our clinical experience in adult-to-adult living donor liver transplantation (ALDLT). METHODS Clinical data of 12 patients with ALDLT performed in our center from September 2000 to June 2005 were analyzed, retrospectively. RESULTS Left lobe (segments II, III, IV, including the middle hepatic veins) transplantation was performed in 3 patients and right lobe (segments V, VI, VII, VIII, with or without the middle hepatic veins) transplantation was performed in 9 patients. Donors: There were no operative deaths. The median operative time was 6.20+/-1.40 hours and their blood loss ranged from 300 ml to 1200 ml. Postoperative complications included biliary fistula (1 donor) and wound fat liquefaction (1 donor). During a 6-12 months follow-up, no long-term complications were found. Recipients: The operating time ranged from 5 to 11 hours and their blood loss ranged from 800 to 7000 ml. Modified outflow reconstruction, microvascular reconstruction of the hepatic artery and duct-to-duct biliary reconstruction were done during the recipient operations. The median cold ischemia time was 1.90+/-0.50 hours. The median anhepatic phase of recipients was 1.63+/-0.43 hours. Graft/recipient weight ratio (GRWR) was (1.20+/-0.26)%. One recipient presented a postoperative complication of biliary fistula and another recipient died 1 month after the operation from serious infection. The other 11 recipients had long-term survivals. CONCLUSION ALDLT is an effective treatment for decompensated end-stage liver disease patients and is relatively safe for the donors.

Abstract
Wilson's disease is a genetic disorder characterized by accumulation of copper in many organs and tissues. Phenotypic manifestations are wide-ranging from neuropsychiatric disorders, to severe liver disease requiring liver transplantation. Clinical presentation is not often related to the genetic defect and siblings may have different type of disease. Liver transplantation is indicated for all patients with Wilson's disease and decompensated liver cirrhosis unresponsive to medical therapy, but its efficacy in resolving the neurological symptoms is still controversial, because as far now, very different outcomes have been reported. We describe here on the exceptional case of two homozygotic twins, both with liver cirrhosis due to Wilson's disease, one of them with severe neuropsychiatric involvement, who both underwent liver transplantation and subsequently had very different outcome despite same genetic background. The presence of neurological clinical manifestations in Wilson's disease should recommend caution indicating liver transplantation, because irreversible brain damage may exist.

Abstract
Feasibility of duct-to-duct biliary reconstruction in adult living related liver transplantation (LRLTx) has been recently reported; however, little has been known of its surgical outcome in children. To assess the feasibility and safety of duct-to-duct biliary reconstruction in children, the surgical outcomes of duct-to-duct biliary reconstruction were retrospectively analyzed. The subjects were three children who underwent LRLTx in our hospital each utilizing allografts with a right lobe, a left robe and a lateral segment, respectively. The cause of end-stage liver disease in each of them was fulminant Wilson's disease, fulminant hepatic failure and unresectable hepatoblastoma. Duct-to-duct anastomosis was performed in younger patients and adolescents with interrupted and continuous sutures, respectively. The diameter of bile duct in allografts was from 4 to 6 mm and 12 or 13 stitches were required for anastomosis. Post-operative choledochography from the external tube showed neither stenosis nor leakage and the tube was evacuated within 3 months after LRLTx. No biliary complications were observed with the median follow-up of 28 months. In conclusion, our results show that duct-to-duct biliary reconstructions in pediatric LRLTx seemed to be feasible and safe. Further studies are required to elucidate its real impact on pediatric LRLTx.

Abstract
A retrospective data analysis on liver transplantation for Wilson's disease (WD) was performed among Italian Liver Transplant Centers. Thirty-seven cases were identified. The main indication for liver transplantation was chronic advanced liver disease in 78% of patients. Mixed hepatic and neuropsychiatric symptoms were recorded in 32.3%. Eight patients presented with fulminant liver failure; 44.8% were on medical treatment. Patient and graft survival at 3 months, 12 months, 3 years, 5 years, and 10 years after transplantation were, respectively, 91.8%, 89.1%, 82.9%, 75.6%, and 58.8%, and 85.3%, 83.0%, 77.1%, 70.3%, and 47.2%. Neurological symptoms significantly improved after orthotopic liver transplantation (OLT), but the survival of patients with mixed hepatic and neuropsychiatric involvement was significantly lower than in patients with liver disease alone (P = 0.04). WD characterized by hepatic involvement alone is a rare but good indication for liver transplantation when specific medical therapy fails. Patients with neuropsychiatric signs have a significantly shorter survival even though liver transplantation has a positive impact on neurological symptoms. In conclusion, a combination of hepatic and neuropsychiatric conditions deserves careful neurological evaluation, which should contraindicate OLT in case of severe neurological impairment.

Abstract
Orthotopic liver transplantation has been applied to the treatment of Wilson's disease (WD), living-related liver transplantation (LRLT) has also been indicated for WD with increasing frequency. Between January 2001 and November 2003, 22 LRLTs were performed on patients (19 pediatric, three adults) with WD in liver transplantation center. Two patients were transplanted because of a presentation coexistent with fulminant hepatic failure. Twenty presented with chronic advanced liver disease with (n = 9) or without (n = 11) associated neurologic manifestations. All the recipients had low serum ceruloplasmin levels with a mean value of 12.8 +/- 3.2 mg/dl before transplantation and increased to an average of 26.0 +/- 3.6 mg/dl after LRLT at the latest evaluation. The survival patients with neurologic manifestations such as tremor, dysarthia, dysphagia, dystonia and sialorrhea had improved after LRLT. This suggests that LRLT not only resolves the hepatic but also ameliorates the neurologic consequences of WD.

Abstract
Liver transplantation with liver grafts from deceased donors is the treatment of choice for patients suffering from Wilson's disease (WD) with end-stage liver disease. There are few reports, however, on the use of liver grafts from living-related donors for WD. Five (two pediatric and three adult recipients) underwent living-related liver transplantation (LRLT) for WD at the University of Tokyo. Two patients presented with fulminant hepatic failure with hemolysis, and the other three presented with decompensating cirrhosis, one with an overlapping neurologic WD. All recipients had a low serum ceruloplasmin level (median: 18 mg/dL), high urinary copper level (mean: 1119 microg/d), and presented with Kayser-Fleischer rings before transplantation. Although one patient died from early graft thrombosis unrelated to WD, the other four patients have shown an excellent long-term prognosis. Following successful transplantation, there was a significant reduction in urinary copper excretion (median: 64 microg/d) in all patients. The neurologic symptoms of WD in one patient, however, worsened after 2 months and gradually subsided, but not completely, over the 2-yr follow-up. For advanced liver failure in WD, we consider LRLT a valuable life-saving option. The improvement of neurologic symptoms, however, requires further evaluation.

Abstract
Surgical techniques that have been used during liver transplantation (LT) together with patient's coagulation profile and institutional practices are reported to have an effect on transfusion requirements. The aim of this study is to evaluate the transfusion requirement in both cadaveric (CDLT, n = 22) and living donor (LDLT, n = 24) pediatric LT performed in our institution. Balanced general anesthesia was used for all patients. Transfusion requirements were met to maintain a hemoglobin concentration of 8-10 g/dL, platelet level >50 x 10(3)/mL, prothrombin time <20 s and hemodynamic course with observing heart rate, arterial and central venous blood pressures and hourly urine output. Blood loss was replaced by using whole blood. Both groups' perioperative total blood and fresh-frozen plasma (FFP) volumes transfused, fluid requirements and hemodynamic courses, standard coagulation profile and metabolic variables determined in time periods of operations, patients' preoperative characteristics, operative features and postoperative events were compared. The mean transfusion requirements were 37.1 +/- 33.4 and 74.8 +/- 90.8 mL/kg of whole blood (p = 0.059) and 34.5 +/- 24.9 and 51.5 +/- 59.7 mL/kg of FFP for CDLT and LDLT, respectively (p = 0.519). The mean ages and mean body weights of the CDLT patients were higher than LDLT patients (9.7 +/- 5.3 vs. 6.6 +/- 4.4 yr, p = 0.015 and 32.4 +/- 17.7 vs. 21.0 +/- 14.8 kg, p = 0.032, respectively) while the mean operation time (493 +/- 135 vs. 323 +/- 93 min, p = 0.0001) and PELD score (13.1 +/- 11.2 vs. 20.1 +/- 11.8, p = 0.036) were higher for LDLT. In the entire population, multiple regression analysis showed that age, body weight and operation time have a significant combined effect on blood consumption (r2= 0.29, p = 0.003) meanwhile operation time was found to be an effective single variable (p = 0.002). None of the single or combined variables was found to have a significant effect on FFP consumption (r2= 0.17, p = 0.63) and crystalloid use (r2= 0.19, p = 0.11). Hemodynamic courses of both groups were similar. The incidences of metabolic acidosis and hypothermia during the anhepatic periods were higher in the CDLT group (p < 0.05). However, transfusion requirement in the ICU were higher in LDLT group [6.9 +/- 2.2 (n = 6) vs. 18.6 +/- 19 (n = 11) mL/kg, p < 0.05] after LT. As a result of this study in a pediatric patient population, no statistical significance was found in whole blood transfusion and FFP requirements between CDLT and LDLT. Duration of the operation was the primary factor effecting transfusion volume showing the importance of continued small volume losses during uncomplicated LT in this small sized patient population. Transfusion need for pediatric LT should be individualized for each patient based on the intraoperative conditions including surgical and patient features.

Abstract
BACKGROUND In Japan ABO-incompatible liver transplantation has been done on >100 occasions up to 2003. However, <30% are cases involving adults. The difficultly of ABO-incompatible liver transplantation is associated with the high frequency of humoral rejection and local disseminated intravascular coagulation (DIC), leading to many postoperative complications. We report a successful case of adult ABO-incompatible liver transplantation with the use of an intrahepatic artery infusion. METHODS A 36-year-old man with Wilson disease, underwent living donor liver transplantation from an ABO-incompatible donor. The immunosuppressive therapy included multiple perioperative plasmaphereses, splenectomy, and treatment with tacrolimus, methylprednisolone, and cyclophosphamide. The dose and blood level of tacrolimus were the same as in ABO-compatible cases. In addition to these therapies, we administered an intrahepatic arterial infusion with prostaglandin (PG) E1 alone. RESULTS After perioperative plasmapheresis and cyclophosphamide, antidonor blood group antibody titers remained undiluted and without vascular complications throughout the postoperative course, but there was a tendency for bleeding that continued for 10 days after transplantation. On postoperative day 10, a reexploration was performed for intraabdominal bleeding. During another operation on postoperative day 59 a biloma was found and drained. The patient has now survived for 120 days after transplantation with normal liver function. CONCLUSIONS Beneficial effect of intrahepatic artery infusion with PGE1 seems to be useful in adult ABO-incompatible liver transplantation.

Abstract
Wilson's disease (WD) is a rare liver-based disorder of copper metabolism. Prognostic criteria described by our group in 1986 to predict death without transplantation have not been universally validated. The clinical features of 88 children were reviewed, retrospectively in 74 and prospectively in 14. Data from the retrospectively recruited patients that died or survived on long-term chelation were used to evaluate the validity of our old scoring system and to devise a new prognostic index, then assessed in the 14 prospectively recruited patients. Using the old scoring system, 5 children scoring > or = 7, the cutoff value for death without transplantation, survived, whereas 4 scoring < or = 7 died (sensitivity 87% and specificity 90%). A new index based on serum bilirubin, international normalized ratio, aspartate aminotransferase (AST), and white cell count (WCC) at presentation identified a cutoff score of 11 for death and proved to be 93% sensitive and 98% specific, with a positive predictive value of 88%. When the new index was evaluated prospectively in 14 patients, it predicted the need for transplantation in only the 4 who required it, although 1 child with a score of 11 survived on medical treatment. In conclusion, the new Wilson Index is more sensitive and specific in predicting mortality without transplantation than the old scoring system, but needs to be validated in a larger number of patients.

Abstract
The orthotopic liver transplantation (OLT) allows survival of children followed for severe hepatic injury, provided that the immunosuppressive treatment is prolonged. The nephrotoxicity of cyclosporine predicts the long-term outcome of the adult patients receiving a liver transplant. The aim of this study was to determine the long-term outcome of renal function in children receiving OLT. This study included 12 children, with a median for age of 7.1 yr (2-15 yr) at the time of OLT. The duration of follow-up was at least 4 yr, being 7 yr in 10 patients and more than 10 yr in seven. Renal function was evaluated with the serum level of creatinine, calculated glomerular filtration rate (cGFR), and measurement of glomerular filtration rate using chrome 51 ethylenediaminetetraacetate ((51)Cr EDTA) clearance performed at least once during follow-up. The doses and the serum concentrations (C(0)) of cyclosporine were reported at each study time. The cGFR decreased significantly 2 yr after the OLT [median (range): 106 mL/min/1.73 m(2) (71-150) at the time of OLT vs. 85 mL/min/1.73 m(2) (57-128) 2 yr after the OLT, p = 0.03], and decreased again between 7 and 10 yr after OLT [median (range): 99 mL/min/1.73 m(2) (76-125) 7 yr after OLT vs. 81 mL/min/1.73 m(2) (66-140) 10 yr after OLT, p = 0.04]. Six patients developed chronic renal failure (cGFR from 57 to 80 mL/min/1.73 m(2)) 2 yr after OLT associated with high doses of cyclosporine [median (range): 8.8 mg/kg/day (3.5-13)]. The cGFR overestimated renal function by 16% compared with the isotopic measurement of GFR (p = 0.03). Using the (51)Cr EDTA measurement, six of seven patients followed up more than 10 yr after OLT presented mild (n = 3) or moderate (n = 3) chronic renal failure. In our study, the majority of OLT recipients developed a chronic renal failure 10 yr after transplantation. Cyclosporine seems to be the most important factor responsible for the impairment of renal function. The use of the mycophenolate mofetil, a new immunosuppressive agent, allowing a reduction in the dose of cyclosporine, could minimize renal dysfunction. While awaiting the results of a prospective long-term study, close drug monitoring is advised.

Abstract
Fulminant hepatic failure (FHF) accounts for 10-15% of pediatric liver transplants in the USA annually. Because the onset of FHF may be the first presentation of Wilson's disease (WD) and autoimmune hepatitis (AIH) in previously asymptomatic adolescents, determination of the etiology of FHF is critical as treatment and prognosis differ between these two entities. Patients with AIH may be salvaged by medical treatment. On the contrary, liver transplantation is currently the only life saving therapeutic option available for patients with WD who present with fulminant liver failure. To establish the diagnosis of WD and AIH in the setting of FHF remains challenging for diagnosticians and decisions regarding liver transplantation may be necessary before a diagnosis is firmly established. We report a previously asymptomatic patient who presented with FHF and clinical and laboratory features suggestive of both WD and AIH and who underwent successful therapeutic liver transplantation before the diagnosis of WD could be confirmed.

Abstract
BACKGROUND AND AIM The toxic milk (tx) mouse is a non-fatal animal model for the metabolic liver disorder, Wilson's disease. The tx mouse has a mutated gene for a copper-transporting protein, causing early copper accumulation in the liver and late accumulation in other tissues. The present study investigated the efficacy of liver cell transplantation (LCT) to correct the tx mouse phenotype. METHODS Congenic hepatocytes were isolated and intrasplenically transplanted into 3-4-month-old tx mice, which were then placed on various copper-loaded diets to examine its influence on repopulation by transplanted cells. The control animals were age-matched untransplanted tx mice. Liver repopulation was determined by comparisons of restriction fragment length polymorphism ratios (DNA and mRNA), and copper levels were measured by atomic absorption spectroscopy. RESULTS Repopulation in recipient tx mice was detected in 11 of 25 animals (44%) at 4 months after LCT. Dietary copper loading (whether given before or after LCT, or both) provided no growth advantage for donor cells, with similar repopulation incidences in all copper treatment groups. Overall, liver copper levels were significantly lower in repopulated animals (538 +/- 68 microg/g, n = 11) compared to non-repopulated animals (866 +/- 62 microg/g, n = 14) and untreated controls (910 +/- 103 microg/g, n = 6; P < 0.05). This effect was also seen in the kidney and spleen. Brain copper levels remained unchanged. CONCLUSION Transplanted liver cells can proliferate and correct a non-fatal metabolic liver disease, with some restoration of hepatic copper homeostasis after 4 months leading to reduced copper levels in the liver and extrahepatic tissues, but not in the brain.
