Abstract
BACKGROUND Acute liver failure (ALF) may be the first and most dramatic presentation of Wilson's disease (WD). ALF due to WD (WD-ALF) is difficult to distinguish from other causes of liver disease and is a clear indication for liver transplantation. There is no firm recommendation on specific and supportive medical treatment for this condition. AIM To critically evaluate the diagnostic and therapeutic management of WD-ALF patients in order to improve their survival with native liver. METHODS A retrospective analysis of patients with WD-ALF was conducted in two pediatric liver units from 2018 to 2023. RESULTS During the study period, 16 children (9 males) received a diagnosis of WD and 2 of them presented with ALF. The first was successfully treated with an unconventional combination of low doses of D-penicillamine and zinc plus steroids, and survived without liver transplant. The second, exclusively treated with supportive therapy, needed a hepatotransplant to overcome ALF. CONCLUSION Successful treatment of 1 WD-ALF patient with low-dose D-penicillamine and zinc plus steroids may provide new perspectives for management of this condition, which is currently only treated with liver transplantation.

Delle Cave V, Di Dato F, Iorio R. Wilson's Disease with Acute Hepatic Onset: How to Diagnose and Treat It. CHILDREN (BASEL, SWITZERLAND) 2024; 11:68. [PMID: 38255382 PMCID: PMC10814100 DOI: 10.3390/children11010068] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 12/19/2023] [Accepted: 01/05/2024] [Indexed: 01/24/2024]
Abstract
Wilson's disease (WD) with acute onset poses a diagnostic challenge because it is clinically indistinguishable from other acute liver diseases. In addition, serum ceruloplasmin and urinary copper excretion, the first-line diagnostic tools for WD, can show false positive results in the case of acute liver failure, and the diagnostic role of genetic analysis is limited by the time required to perform it. In the case of fulminant onset, there is a clear indication of liver transplantation. "New Wilson Index" is frequently used to discriminate between patients who need liver transplantation versus those who can be successfully managed by medical treatment, but its reliability remains controversial. Timely referral of patients with acute liver failure due to WD may be a key factor in improving patient survival. Although liver transplant very often represents the only chance for such patients, maximum effort should be made to promote survival with a native liver. The management of these aspects of WD is still a matter of debate and will be the subject of this review.

Distribution of non-ceruloplasmin-bound copper after i.v. 64Cu injection studied with PET/CT in patients with Wilson disease. JHEP Rep 2023; 5:100916. [PMID: 37886434 PMCID: PMC10597763 DOI: 10.1016/j.jhepr.2023.100916] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 08/31/2023] [Accepted: 08/31/2023] [Indexed: 10/28/2023] Open
Abstract
Background & Aims In Wilson disease (WD), copper accumulation and increased non-ceruloplasmin-bound copper in plasma lead to liver and brain pathology. To better understand the fate of non-ceruloplasmin-bound copper, we used PET/CT to examine the whole-body distribution of intravenously injected 64-copper (64Cu). Methods Eight patients with WD, five heterozygotes, and nine healthy controls were examined by dynamic PET/CT for 90 min and static PET/CT up to 20 h after injection. We measured 64Cu activity in blood and tissue and quantified the kinetics by compartmental analysis. Results Initially, a large fraction of injected 64Cu was distributed to extrahepatic tissues, especially skeletal muscle. Thus, across groups, extrahepatic tissues accounted for 45-58% of the injected dose (%ID) after 10 min, and 45-55% after 1 h. Kinetic analysis showed rapid exchange of 64Cu between blood and muscle as well as adipose tissue, with 64Cu retention in a secondary compartment, possibly mitochondria. This way, muscle and adipose tissue may protect the brain from spikes in non-ceruloplasmin-bound copper. Tiny amounts of cerebral 64Cu were detected (0.2%ID after 90 min and 0.3%ID after 6 h), suggesting tight control of cerebral copper in accordance with a cerebral clearance that is 2-3-fold lower than in muscle. Compared to controls, patients with WD accumulated more hepatic copper 6-20 h after injection, and also renal copper at 6 h. Conclusion Non-ceruloplasmin-bound copper is initially distributed into a number of tissues before being redistributed slowly to the eliminating organ, the liver. Cerebral uptake of copper is extremely slow and likely highly regulated. Our findings provide new insights into the mechanisms of copper control. Impact and implications Maintaining non-ceruloplasmin-bound copper within the normal range is an important treatment goal in WD as this "free" copper is considered toxic to the liver and brain. We found that intravenously injected non-ceruloplasmin-bound copper quickly distributed to a number of tissues, especially skeletal muscle, subcutaneous fat, and the liver, while uptake into the brain was slow. This study offers new insights into the mechanisms of copper control, which may encourage further research into potential new treatment targets. Clinical trial number 2016-001975-59.

Abstract
Wilson's disease is a rare genetic condition that affects copper metabolism, resulting in tissue copper accumulation and resultant organ damage. We report a case of a young woman who presents with Wilson's disease complicated by hemolysis, impaired hepatic function, coagulopathy, and acute kidney injury. She was treated with plasmapheresis as a bridge to a liver transplant. Her mental state, renal function, and bilirubin level improved after starting plasmapheresis. She successfully underwent a liver transplant and remained stable post-liver transplant. We share our experience on the use of plasmapheresis in treating Wilson's disease.

Abstract
Wilson disease (WD) is caused by autosomal variants affecting the ATP7B gene on chromosome 13, resulting in alterations in physiological copper homeostasis and copper accumulation. Excess copper clinically manifests in many organs, most often in the central nervous system and liver, ultimately causing cirrhosis and death. Often considered a pediatric or young adult disease, WD actually affects patients of all ages, and aging patients need to be regularly managed with long-term follow-up. Despite over a century of advances in diagnosis and treatment, WD is still associated with diagnostic challenges and considerable disability and death, in part due to delays in diagnosis and limitations in treatment. Standard-of-care treatments are considered generally effective when the diagnosis is timely but are also limited by efficacy, safety concerns, multiple daily dosing, and adherence. This expert perspective review seeks to facilitate improvements in the awareness, understanding, diagnosis, and management of WD. The objectives are to provide a full overview of WD and streamline updated diagnosis and treatment guidance, as recently published by the American Association for the Study of Liver Diseases, in a practical way for clinical use.

Abstract
INTRODUCTION Wilson's disease may lead to cirrhosis, but timely medical treatment could slow down its progression. Clinical markers helping early diagnosis are essential. Decreased fetuin-A concentration has been reported in cirrhosis of different etiologies. The aim of this study was to investigate whether decreased serum fetuin-A concentration could identify patients with Wilson's disease who developed cirrhosis. MATERIALS AND METHODS In this cross-sectional study we determined the serum fetuin-A concentration of 50 patients with Wilson's disease. We analyzed the data of patients with liver involvement, comparing cirrhotic and non-cirrhotic patients. RESULTS Among patients with liver involvement those with cirrhosis had significantly lower fetuin-A and albumin level, white blood cell and platelet count. Fetuin-A negatively correlated with disease duration, bilirubin level, positively with total protein and albumin concentration, but not with copper and ceruloplasmin concentrations or markers of systemic inflammation. In multivariate analysis with fetuin-A and the Nazer score or its parameters only fetuin-A was a significant determinant of having cirrhosis. In receiver operator curve analysis among patients with liver involvement the fetuin-A level of 523 μg/ml was associated with cirrhosis with 82% sensitivity and 87% specificity. The presence of the H1069Q mutation was not associated with alteration in fetuin-A concentration. CONCLUSIONS The serum concentration of fetuin-A is a sensitive marker of liver cirrhosis in Wilson's disease, independently of the H1069Q mutation, ceruloplasmin concentration or systemic inflammation.

Abstract
The silver anniversary of the discovery of the Wilson disease gene ATP7B was a couple of years ago, and we continue to make progress both in our understanding of copper transportation using animal models as well as earlier diagnosis by availing of genetic testing. Wilson disease is multisystemic and the hepatic manifestations are seen more frequently in childhood, whereas neurologic manifestations are more common in adults; presentation may range from subtle changes to end-stage liver disease with or without encephalopathy as well as neuropsychiatric manifestations. Treatment remains with zinc and chelating agents such as D-penicillamine and trientine but newer agents and gene therapy are in clinical trials. Liver transplantation becomes necessary when medical therapy is not enough. Molecular diagnosis and genetic counseling is important.

Abstract
BACKGROUND The prognosis of Wilson's disease (WD) has changed radically since the introduction of medical therapy with chelators and zinc. However, there is an unmet need for methods to evaluate the long-term treatment response and the liver disease progression in order to identify treatment failures. The galactose elimination capacity test (GEC) is a physiological measure of the total metabolic capacity of the liver, and a strong predictor of long- and short-term mortality in patients with liver cirrhosis. Our aim was to investigate if the GEC test is useful for evaluation of treatment response and prediction of treatment failures in WD patients. METHODS We included all patients with WD in Denmark from 1992 through 2017 and retrieved data on GEC along with data on transplantation and death. RESULTS In total, 37 patients had completed one or more GEC tests. Of these, 31 were alive (three transplanted) and six were dead (two transplanted). A total of 24 patients had completed more than one GEC test. All 18 alive, nontransplanted patients showed improvement in GEC values following onset of treatment, except one patient, who was clinically confirmed with treatment failure. All six patients who underwent liver transplantation or died had a prior decline in their GEC. The difference in GEC development between patients alive and not transplanted and patients dead or transplanted was significant (p < .001). Index GEC values could not predict transplantation or death (p = .26). CONCLUSION The GEC test is a promising tool for monitoring treatment response and identifying treatment failures in patients with WD.

Abstract
OBJECTIVES Liver transplantation (LT) in Wilson disease (WD) is a life-saving option for patients presenting with liver failure and encephalopathy. Patients without encephalopathy can avoid LT and treated successfully with chelation therapy. It is essential to predict the risk of fatal outcomes where LT is required. We aim to critically analyse the validity of the WD Index prospectively from a cohort of WD patients managed at our institution. METHODS WD Index and other clinical data from 2005 to 2018, recorded prospectively as part of clinical management, were analysed. RESULTS Over 13-year period, 52 children with WD (29 boys) with median age at diagnosis of 11.69 (range 3.92-17.26) years were studied. Of these, 17 were diagnosed as part of family screening, 17 presented with abnormal liver enzyme, and 18 with acute hepatic decompensation (AHD) as per PALF definition. Patients presented with abnormal liver enzyme and in the pre-symptomatic group had WD Index <11, and none of them required LT. WD Index is still a good predictor for LT in WD patients with AHD, providing a sensitivity of 80%, specificity of 100%, positive-predictive, and negative-predictive value of 100% and 80%, respectively. Patients presented with an index of 8-10 also required LT at median duration of 58 days (IQR 48-135 days). CONCLUSIONS WD patients presenting with AHD who had an index of ≥11 do require LT. Children with a WD Index of 8 to 10 within the first 2 months of admission require close monitoring as LT may become necessary.

Abstract
OBJECTIVES In children, acute liver failure (ALF) is a severe condition with high mortality. As some patients need liver transplantation (LT), it is essential to predict the fatal evolution and to refer them early for LT if needed. Our study aimed to evaluate the prognostic criteria and scores for assessing the outcome in children with ALF. METHODS Data of 161 children with ALF (54.66% female, mean age 7.66 ± 6.18 years) were analyzed based on final evolution (32.91% with fatal evolution or LT) and etiology. We calculated on the first day of hospitalization the PELD score (109 children), MELD, and MELD-Na score (52 children), and King's College Criteria (KCC) for all patients. The Nazer prognostic index and Wilson index for predicting mortality were calculated for nine patients with ALF in Wilson's disease (WD). RESULTS PELD, MELD, and MELD-Na scores were significantly higher in patients with fatal evolution (21.04 ± 13.28 vs. 13.99 ± 10.07, p = 0.0023; 36.20 ± 19.51 vs. 20.08 ± 8.57, p < 0.0001; and 33.07 ± 8.29 vs. 20.08 ± 8.47, p < 0.0001, respectively). Moreover, age, bilirubin, albumin, INR, and hemoglobin significantly differed in children with fatal evolution. Function to etiology, PELD, MELD, MELD-Na, and KCC accurately predicted fatal evolution in toxic ALF (25.33 vs. 9.90, p = 0.0032; 37.29 vs. 18.79, p < 0.0001; 34.29 vs. 19.24, p = 0.0002, respectively; with positive predicting value 100%, negative predicting value 88.52%, and accuracy 89.23% for King's College criteria). The Wilson index for predicting mortality had an excellent predictive strength (100% sensibility and specificity), better than the Nazer prognostic index. CONCLUSIONS Prognostic scores may be used to predict the fatal evolution of ALF in children in correlation with other parameters or criteria. Early estimation of the outcome of ALF is essential, mainly in countries where emergency LT is problematic, as the transfer to a specialized center could be delayed, affecting survival chances.

Abstract
BACKGROUND Wilson's disease (WD) is a rare cause of acute liver failure (ALF) and has a high fatality rate. Rapid and accurate diagnosis is important for ALF because of WD (ALF-WD). Our objective was to establish a simple, rapid, and accurate diagnostic test to distinguish ALF-WD from non-WD ALF (NWDALF) in children. MATERIALS AND METHODS The data from all cases with pediatric ALF were retrospectively collected and analyzed. We performed receiver operator characteristics curve (ROC) analysis and confirmed the optimum cut-off points. RESULTS Fifty-eight patients with pediatric ALF (12 with WD, 46 with other etiologies) were included. Older age was observed in ALF-WD compared to NWDALF (11.16 ± 2.51 years vs. 3.34 ± 3.81 years, p < 0.001). An analysis based on routine biochemical testings revealed that total bilirubin (TBil), direct bilirubin, indirect bilirubin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), AST:ALT ratio, alkaline phosphatase (ALP), ALP:TBil ratio, serum albumin, gamma-glutamyl transferase, cholinesterase, hemoglobin, and platelet were statistically significant between the ALF-WD and NWDALF groups. The optimum cut-off points were obtained through ROC analysis. A scoring system was formed by assigning a score of 1 or 0 to patients who met the 13 cut-off points. Using ROC analysis, we determined a cut-off point of ≥ 6.5 for ALF-WD with 91.7% sensitivity and 97.8% specificity (p < 0.0001). In addition, a best cut-off point of ≥ 1.5 based on only five variables (ALT, AST, AST:ALT ratio, ALP, and ALP:TBil ratio), had 100% sensitivity and 91.3% specificity for ALF-WD (p < 0.0001). Based on this, when age was calculated as the sixth indicator, the best cut-off value of ≥ 2.5 had 100% sensitivity and 97.8% specificity (p < 00.0001). CONCLUSION Our study developed a new scoring system that consists of simple laboratory tests with good sensitivity and specificity and can be used by clinicians to quickly distinguish ALF-WD from NWDALF in children.

Pop TL, Grama A, Stefanescu AC, Willheim C, Ferenci P. Acute liver failure with hemolytic anemia in children with Wilson’s disease: Genotype-phenotype correlations? World J Hepatol 2021; 13:1428-1438. [PMID: 34786177 PMCID: PMC8568583 DOI: 10.4254/wjh.v13.i10.1428] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Revised: 06/23/2021] [Accepted: 09/03/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Wilson’s disease (WD) is a rare autosomal recessive inherited disorder of copper metabolism. Acute liver failure (ALF) and hemolytic anemia represent the most severe presentation of WD in children. No clear genotype-phenotype correlations exist in WD. Protein-truncating nonsense, frame-shift, or splice-site variants may be associated with more severe disease. In contrast, missense variants may be associated with late-onset, less severe disease, and more neurological manifestations. Recently, a gene variant (HSD17B13:TA, rs72613567) with a possible hepatic protective role against toxins was associated with a less severe hepatic phenotype in WD.
AIM To analyze the possible genotype-phenotype correlations in children with WD presented with ALF and non-immune hemolytic anemia.
METHODS The medical records of children with WD diagnosed and treated in our hospital from January 2006 to December 2020 were retrospectively analyzed. The clinical manifestations (ALF with non-immune hemolytic anemia or other less severe forms), laboratory parameters, copper metabolism, ATP7B variants, and the HSD17B13:TA (rs72613567) variant were reviewed to analyze the possible genotype-phenotype correlations.
RESULTS We analyzed the data of 51 patients with WD, 26 females (50.98%), with the mean age at the diagnosis of 12.36 ± 3.74 years. ALF and Coombs-negative hemolytic anemia was present in 8 children (15.67%), all adolescent girls. The Kayser-Fleisher ring was present in 9 children (17.65%). The most frequent variants of the ATP7B gene were p.His1069Gln (c.3207A>G) in 38.24% of all alleles, p.Gly1341Asp (c.4021G>A) in 26.47%, p.Trp939Cys (c.2817G>T) in 9.80%, and p.Lys844Ter (c.2530A>T) in 4.90%. In ALF with hemolytic anemia, p.Trp939Cys (c.2817G>T) and p.Lys844Ter (c.2530A>T) variants were more frequent than in other less severe forms, in which p.His1069Gln (c.3207A>G) was more frequent. p.Gly1341Asp (c.4021G>A) has a similar frequency in all hepatic forms. For 33 of the patients, the HSD17B13 genotype was evaluated. The overall HSD17B13:TA allele frequency was 24.24%. Its frequency was higher in patients with less severe liver disease (26.92%) than those with ALF and hemolytic anemia (14.28%).
CONCLUSION It remains challenging to prove a genotype-phenotype correlation in WD patients. In children with ALF and hemolytic anemia, the missense variants other than p.His1069Gln (c.3207A>G) and frame-shift variants were the most frequently present in homozygous status or compound heterozygous status with site splice variants. As genetic analysis is usually time-consuming and the results are late, the importance at the onset of the ALF is questionable. If variants proved to be associated with severe forms are found in the pre-symptomatic phase of the disease, this could be essential to predict a possible severe evolution.

Abstract
Wilson's disease (WD) is an autosomal recessive genetic disorder of copper metabolism leading to liver or brain injury due to accumulation of copper. Diagnosis is based on: clinical features, biochemical tests including plasma ceruloplasmin concentration, 24h urinary copper excretion, copper content in the liver, and molecular analysis. Pharmacological therapy comprises chelating agents (penicillamine, trientine) and zinc salts which seem to be very effective. Still, poor compliance is a major problem. Adolescents and patients with psychiatric disorders usually have problems with adherence to treatment. As transition is a vulnerable period transition ''training'' should start before the planned transfer, preferably already in early adolescence in cooperation between adult and pediatric clinics. Response to treatment is assessed based on physical examination, normal liver function tests and monitoring of copper metabolism markers. Liver transplantation has a well-defined role in Wilsonian acute hepatic failure according to the prognostic score. The long-term survival in WD patients seems to be very similar as for the general population if disease is early diagnosed and correctly treated. WD patients with a longer delay from diagnosis to therapy and who present with neurological and psychiatric symptoms have worse quality of life.

Abstract
OBJECTIVES To describe a cohort of Wilson disease (WD) pediatric cases, and to point out the diagnostic particularities of this age group and the long-term outcome. METHODS Clinical data of 182 pediatric patients included in the French WD national registry from 01/03/1995 to 01/06/2019 were gathered. RESULTS Diagnosis of WD was made at a mean age of 10.7 ± 4.2 years (range 1-18 years). At diagnosis, 154 patients (84.6%) had hepatic manifestations, 19 (10.4%) had neurological manifestations, and 9 patients (4.9%) were asymptomatic. The p.His1069Gln mutation was the most frequently encountered (14% of patients).Neurological patients were diagnosed at least 1 year after they presented their first symptoms. At diagnosis, the median urinary copper excretion (UCE) was 4.2 μmol/24 hours (0.2-253). The first-line treatment was d-penicillamine (DP) for 131 (72%) patients, zinc salts for 24 (13%) patients, and Trientine for 17 (9%) patients. Liver transplantation was performed in 39 (21.4%) patients, for hepatic indications in 33 of 39 patients or for neurological deterioration in 6 of 39 patients, mean Unified Wilson's Disease Rating Scale of the latter went from 90 ± 23.1 before liver transplantation (LT) to 26.8 ± 14.1 (P < 0.01) after a mean follow-up of 4.3 ± 2.5 years. Overall survival rate at 20 years of follow-up was 98%, patient and transplant-free combined survival was 84% at 20 years. CONCLUSION Diagnosis of WD can be challenging in children, particularly at the early stages of liver disease and in case of neurological presentation; hence the support of clinical scores and genetic testing is essential. Diagnosis at early stages and proper treatment ensure excellent outcomes, subject to good long-term treatment compliance. LT is a valid option for end-stage liver disease not responding to treatment and can be discussed for selected cases of neurological deterioration.

Diagnosis of Wilson Disease and Its Phenotypes by Using Artificial Intelligence. Biomolecules 2021; 11:biom11081243.

Abstract
WD is caused by ATP7B variants disrupting copper efflux resulting in excessive copper accumulation mainly in liver and brain. The diagnosis of WD is challenged by its variable clinical course, onset, morbidity, and ATP7B variant type. Currently it is diagnosed by a combination of clinical symptoms/signs, aberrant copper metabolism parameters (e.g., low ceruloplasmin serum levels and high urinary and hepatic copper concentrations), and genetic evidence of ATP7B mutations when available. As early diagnosis and treatment are key to favorable outcomes, it is critical to identify subjects before the onset of overtly detrimental clinical manifestations. To this end, we sought to improve WD diagnosis using artificial neural network algorithms (part of artificial intelligence) by integrating available clinical and molecular parameters. Surprisingly, WD diagnosis was based on plasma levels of glutamate, asparagine, taurine, and Fischer's ratio. As these amino acids are linked to the urea-Krebs' cycles, our study not only underscores the central role of hepatic mitochondria in WD pathology but also that most WD patients have underlying hepatic dysfunction. Our study provides novel evidence that artificial intelligence utilized for integrated analysis for WD may result in earlier diagnosis and mechanistically relevant treatments for patients with WD.

Abstract
Wilson's disease (WD) is a rare condition caused by copper accumulation primarily in the liver and secondly in other organs, such as the central nervous system. It is a hereditary autosomal recessive disease caused by a deficiency in the ATP7B transporter. This protein facilitates the incorporation of copper into ceruloplasmin. More than 800 mutations associated with WD have been described. The onset of the disease frequently includes manifestations related to the liver (as chronic liver disease or acute liver failure) and neurological symptoms, although it can sometimes be asymptomatic. Despite it being more frequent in young people, WD has been described in all life stages. Due to its fatal prognosis, WD should be suspected in all patients with unexplained biochemical liver abnormalities or neurological or psychiatric symptoms. The diagnosis is established with a combination of clinical signs and tests, including the measurement of ceruloplasmin, urinary copper excretion, copper quantification in liver biopsy, or genetic assessment. The pharmacological therapies include chelating drugs, such as D-penicillamine or trientine, and zinc salts, which are able to change the natural history of the disease, increasing the survival of these patients. In some cases of end-stage liver disease or acute liver failure, liver transplantation must be an option to increase survival. In this narrative review, we offer an overview of WD, focusing on the importance of clinical suspicion, the correct diagnosis, and treatment.

Abstract
Background Wilson’s disease (WD) manifesting as acute liver failure (ALF) is a life-threatening condition, and spontaneous recovery is rare. Diagnostic scores like the alkaline phosphatase elevation/total bilirubin elevation ratio and aspartate aminotransferase/alanine aminotransferase ratio can distinguish WD from other ALF etiologies. Liver transplantation plays a major role in treating these patients, and the revised Wilson Index is useful in patient selection for this procedure. The aim of this study was to evaluate diagnostic scores, treatments, and outcomes of a large cohort of patients with WD-ALF. Material/Methods Twenty adult patients of a historical cohort admitted from January 2001 to December 2017 were prospectively observed. Demographic, clinical, laboratory, and radiology data, and treatment, time on the waiting list for liver transplantation, and outcomes were recorded. Results No diagnostic laboratory scores were 100% positive in patients with WD-ALF. Cut-off values for the alkaline phosphatase/total bilirubin ratio and aspartate aminotransferase/alanine aminotransferase ratio were met by 65.0% and 80.0% of patients, respectively. All patients met at least 1 criterion for high risk of death (Nazer or revised Wilson Index) and qualified for liver transplantation. In 9 patients, albumin dialysis was used before surgery. Survival after liver transplantation was 85.0% and 74.4% after 1 month and 1 year, respectively. Conclusions Further research on a novel diagnostic score in WD-ALF is warranted. Adult patients suspected to have WD as the cause of ALF should be treated in the referral liver transplantation unit. Liver transplantation makes long-term survival possible for patients with this critical illness.

Abstract
OBJECTIVES Since 2005, a New Wilson Index (NWI) ≥11 is used as a predictor of death without transplantation in fulminant Wilson disease (WD). Plasma exchange is advocated as a new treatment modality. METHODS We present a patient with fulminant WD treated with plasma exchange. All published cases applying plasma exchange for fulminant WD were reviewed systematically. RESULTS A 14-year-old girl presented with hemolysis and fulminant liver failure. She had no encephalopathy; NWI was 14. As a bridge to transplantation plasma exchange was started immediately. Complete remission was achieved with plasma exchange and later chelation therapy with D-penicillamine. She is now at 3-year transplant-free survival. Literature review identified 37 patients presenting with fulminant WD and NWI ≥11 who were treated with plasma exchange. Seventeen of these patients (ie, 46%) recovered without transplantation. CONCLUSIONS Multiple case reports and case series demonstrate transplant free survival after plasma exchange and subsequent chelation therapy, despite a NWI ≥11. Plasma exchange affects the clinical course and is a therapeutic option in children and young adults presenting with fulminant WD.

Abstract
Wilson's disease (WD) is a rare cause of acute liver failure (ALF) that is thought to have a uniformly fatal outcome without liver transplantation (LT). Previous studies proposed diagnostic and prognostic criteria for WD-ALF. It is not known whether these apply to WD patients presenting as severe acute liver injury (ALI) without encephalopathy. From 2008 to 2018, 822 patients with ALI in the US Acute Liver Failure Study Group (ALFSG) registry were enrolled and prospectively followed. The diagnosis of WD-ALI was confirmed in 8 patients. Serum biochemical diagnostic ratios predicting WD-ALF (alkaline phosphatase [ALP]:total bilirubin(TB) and aspartate aminotransferase [AST]:alanine aminotransferase [ALT]) were determined in these patients, and predictors of prognosis for WD-ALI were evaluated. Of these 8 ALI-WD patients, 5 received an LT. Ratios of both ALP:TB of <4 and AST:ALT of >2.2 on study admission were met in 4 LT patients. All LT patients were female. The Model for End-Stage Liver Disease scores on admission were generally higher in LT patients. All transplanted patients had an initial revised WD score of >11 (>10 predicting poor outcome without LT in WD-ALF), whereas in non-LT patients, 2 had scores of 9, and 1 a score of 13. Also, 3 LT patients were started on chelation therapy, 2 were started on plasmapheresis, and 1 was started on Molecular Adsorbent Recirculating System therapy. All non-LT patients were treated with chelation. At 21 days, all patients were alive and discharged from the hospital. In conclusion, some patients with ALI due to WD may survive without LT. Revised Wilson index scores >10 predict poor outcome in most patients with WD-ALI, as they do for WD-ALF, and they correlate positively with the ALI model in this cohort. Biochemical ratios for WD diagnosis appear more applicable to ALF compared with WD-ALI.

Abstract
BACKGROUND Wilson's disease is a rare cause of acute liver failure and is highly fatal without liver transplantation. Fast and accurate diagnostic methods are needed for fulminant Wilson's disease (FWD). In this study, we aimed to develop an early, simple and accurate diagnostic method to differentiate FWD from nonwilsonian acute liver failure (NWALF) causes using routine biochemical data. METHODS The medical records of 24 paediatric FWD and 120 paediatric NWALF cases diagnosed at the Department of Pediatric Gastroenterology, Hepatology, and Nutrition between January 2007 and February 2017 were retrospectively reviewed. RESULTS Using receiver operator characteristics curve (ROC) analysis, we have determined the best cut-off point for laboratory findings in FWD. Patients meeting these cut-off points were assigned one point and others were assigned zero point. We then formed a new variable consisting of the combination of 14 variables and performed a new ROC analysis. We obtained a cut-off point of ≥4.5 for FWD. The diagnostic performance of the score was characterized by a sensitivity of 0.889, a specificity of 0.879 (P < .001). A scoring system based only on aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase, AST/ALT ratio, uric acid and haemoglobin had a best cut-off point of ≥2.5 for FWD, which had a sensitivity of 0.875, a specificity of 0.867 (P < .001). CONCLUSIONS Our study demonstrated that biochemical markers offer almost as reliable, fast and accurate diagnosis of FWD as offered by ceruloplasmin and 24-hour urinary copper.

Abstract
BACKGROUND Wilson disease (WD) is a rare copper metabolism disorder with symptoms including hepatic disorders, neuropsychiatric abnormalities, Kayser-Fleischer rings, and hemolysis in association with acute liver failure (ALF). Osteoarthritis is a rare manifestation of WD. We experienced a case of WD with arthritic pain in the knee and liver cirrhosis. Here, we report the clinical course in a WD patient with arthritic pain and liver cirrhosis receiving combination therapy with Zn and a chelator and discuss the cause of arthritic pain.
CASE SUMMARY We present an 11-year-old boy who developed osteoarthritis symptoms and ALF, with a New Wilson Index Score (NWIS) of 12. He was diagnosed with WD with decreased serum ceruloplasmin and copper levels, increased urinary copper excretion, and ATP7B gene mutations detected on gene analysis. There was improvement in the liver cirrhosis, leading to almost normal liver function and liver imaging, one year after receiving combination therapy with Zn and a chelator. Moreover, his arthritic pain transiently deteriorated but eventually improved with a decrease in the blood alkaline phosphatase levels following treatment.
CONCLUSION Patients with WD who develop ALF with an NWIS > 11 may survive after treatment with Zn and chelators, without liver transplantation, when they present with mild hyperbilirubinemia and stage ≤ II hepatic encephalopathy. Osteoarthritis symptoms may improve with long-term Zn and chelator therapy without correlation of liver function in WD.

Abstract
Wilson disease is a rare hereditary disorder of copper metabolism. The genetic defect is caused by various mutations in the copper-transporting enzyme ATP7B, located mainly in the liver and brain. Clinical symptoms are highly variable, with any combination of hepatic and/or neurological or psychiatric manifestations. The age of onset varies from early childhood to young adults and can even be manifested in later ages. The clinical diagnosis is based on a combination of clinical, biochemical and molecular markers. Treatment using chelating agents and zinc salts is effective when started early or even better at presymptomatic stages of the disease.

Effects of Super Nutritional Hepatic Copper Accumulation on Hepatocyte Health and Oxidative Stress in Dairy Cows. Vet Med Int 2019; 2019:3642954. [PMID: 31191898 PMCID: PMC6525807 DOI: 10.1155/2019/3642954] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2019] [Revised: 04/08/2019] [Accepted: 04/21/2019] [Indexed: 01/13/2023] Open
Abstract
Concerns regarding excessive hepatic copper concentrations in dairy cows have increased. The objective of this study was to determine the association of hepatic copper concentrations with evidence of liver disease. Blood and liver samples were collected at the time of slaughter in cull dairy cows (n=100). Liver samples were analyzed for copper using inductively coupled plasma mass spectrometry and crude fat using liquid-liquid extraction and gravimetry. Serum samples were analyzed for glutamate dehydrogenase, γ-glutamyltransferase, sorbitol dehydrogenase, aspartate aminotransferase activities, and bile acid concentrations. Liver samples were examined histologically for inflammation, fibrosis, and rhodanine staining. Animals were stratified by hepatic copper concentration and samples in the highest and lowest quintiles (Q5 and Q1) were evaluated for oxidative stress. Systemic indices of oxidative stress included serum reactive oxygen and nitrogen species (RONS) and total antioxidant potential (AOP). Tissue-level oxidative stress was assessed by immunohistochemistry using 4-hydroxynonenal (4HNE) and 3-nitrotyrosine (3NIT) stains to score the relative abundance and distribution of oxidized lipid and protein products, respectively. Mean hepatic copper concentration was 496.83 μg/g and median 469.72 μg/g and ranged from 70.56 to 1264.27 μg/g dry tissue. No association was found between hepatic copper concentrations and clinicopathological or histological evidence of hepatic damage or dysfunction. There was a significant increase in the amount of IHC staining of 4HNE and 3NIT in Q5 compared with Q1. Moreover, the IHC staining mirrored the distribution of the copper-specific stain rhodanine. These results demonstrate that cows with elevated hepatic copper concentrations had no evidence of active liver disease but had increased hepatic oxidative stress.

Abstract
In Wilson disease (WD) severity of disease can vary widely, depending on time of diagnosis. Early treatment can prevent the development of symptoms in patients. In all patients, lifelong medical treatment is indicated. Currently available medical regimens include the copper chelators for example D-penicillamine (DPA) or trientine (TETA), acting to increase copper excretion and zinc salts (ZS), which reduce copper uptake. In this chapter, we discuss considerations regarding choice of drug and safety limitations.

Abstract
INTRODUCTION AND AIM Wilson's disease (WD) is an uncommon cause of acute liver failure (ALF). Our aim was to describe clinical features, diagnostic findings, treatments, and outcomes of patients with ALF due to WD. MATERIAL AND METHODS Retrospective medical record reviews of all patients with ALF due to WD in eight years in Uruguay. RESULTS WD was the cause of six (15%) of thirty-nine ALF cases. All patients were females, with a mean age of 18 years. Four patients presented with hyperacute liver failure and two with acute failure. Jaundice was the main complaint of all patients. Mean total bilirubin (TB), alkaline phosphatase (AP), AST, and ALT were 27.5 mg/dL, 45.5 lU/l, 156 IU/L, and 51 IU/L, respectively. Ceruloplasmin levels were low in four patients, urinary cooper was high in four, and two had Kayser-Fleischer rings. All patients had Coombs-negative hemolytic anemia, acute kidney injury, histochemical identifiable copper, and advanced fibrosis on liver histology. The average MELD score was 36. All patients were treated with d-penicillamine and listed for urgent liver transplantation (LT). Prometheus® was performed in one patient. Three patients died: two without LT and one after LT. Three patients survived: one without LT (New Wilson Index<11) and two with LT. The referral time to the program and the total time (referral plus waiting list time) were longer for non-survivors than for survivors (14 vs. 3 days and 23 vs. 8 respectively). CONCLUSION All cases had typical clinical, analytical and histopathology characteristics. Early referral was determinant of prognosis.

Abstract
Wilson disease (WD) is an autosomal recessively-inherited disorder of copper metabolism and characterised by a pathological accumulation of copper. The ATP7B gene encodes for a transmembrane copper transporter essential for biliary copper excretion. Depending on time of diagnosis, severity of disease can vary widely. Almost all patients show evidence of progressive liver disease. Neurological impairments or psychiatric symptoms are common in WD patients not diagnosed during adolescence. WD is a treatable disorder, and early treatment can prevent the development of symptoms in patients diagnosed while still asymptomatic. This is why the early diagnosis of WD is crucial. The diagnosis is based on clinical symptoms, abnormal measures of copper metabolism and DNA analysis. Available treatment includes chelators and zinc salts which increase copper excretion and reduce copper uptake. In severe cases, liver transplantation is indicated and accomplishes a phenotypic correction of the hepatic gene defect. Recently, clinical development of the new copper modulating agent tetrathiomolybdate has started and direct genetic therapies are being tested in animal models. The following review focuses especially on biochemical markers and how they can be utilised in diagnosis and drug monitoring.

Abstract
BACKGROUND AND AIMS Acute on chronic liver failure (ACLF) is an emerging entity whose unique pathogenesis, presentation, and outcome are different from those with decompensated cirrhosis. Patients with Wilson disease (WD) often present with ACLF. The outcome in this setting and predictors of mortality have not been well delineated. We describe the clinical features, laboratory characteristics, and prognostic factors in patients with WD with ACLF. We compared the outcome in those without criteria for ACLF. PATIENTS AND METHODS We analyzed the admission characteristics of 68 patients with WD presenting with features of ACLF among a cohort of WD patients from 1997 to 2017. WD was diagnosed as per European association for the study of the liver (EASL)/Leipzig criteria and ACLF by the Asia-Pacific Association of Study of Liver and World Gastroenterology Organization consensus criteria. Factors associated with mortality were analyzed by univariate followed by multivariate analysis and receiver operating characteristic curve. RESULTS Of the 272 patients with WD, 68 fulfilled criteria for ACLF. The mean age was 14.4 years (Range 5-42 years). Males constituted 38/68 (56%). Acute viral or drug induced hepatitis as precipitating factors was seen in 11.7%. Forty-nine patients (49/67; 73%) died including 30/32 (93.8%) with encephalopathy and 45/62 (72.6%) with ascites. Prognostic factors on univariate analysis significant for mortality included encephalopathy, international normalized ratio, white blood cell count and model for end-stage liver disease (MELD) score. On multivariate analysis, only encephalopathy was significant with 82% accuracy in differentiating survivors versus non-survivors. Post mortem liver biopsy in 21 patients and explant biopsy in 2 patients showed features of cirrhosis in all. CONCLUSIONS WD with ACLF is associated with a high mortality Precipitating factors such as viral and drug-induced hepatitis was seen in 11.7% patients. Liver histology in patients subjected to biopsy showed cirrhosis in all. Only encephalopathy is a prognostic marker of non-survival with an accuracy of 82%.

Abstract
Clinical practice guidelines for Wilson's disease (WD) have been published by the American Association for the Study of Liver Diseases and European Association for the Study of the Liver in 2008 and 2012, respectively. Their focus was on the hepatic aspects of the disease. Recently, a position paper on pediatric WD was published by the European Society of Pediatric Gastroenterology Hepatology and Nutrition. A need was felt to harmonize guidelines for the hepatic, pediatric, and neurological aspects of the disease and contextualize them to the resource-constrained settings. Therefore, experts from national societies from India representing 3 disciplines, hepatology (Indian National Association for Study of the Liver), pediatric hepatology (Indian Society of Pediatric Gastroenterology, Hepatology and Nutrition), and neurology (Movement Disorders Society of India) got together to evolve fresh guidelines. A literature search on retrospective and prospective studies of WD using MEDLINE (PubMed) was performed. Members voted on each recommendation, using the nominal voting technique. The Grades of Recommendation, Assessment, Development and Evaluation system was used to determine the quality of evidence. Questions related to diagnostic tests, scoring system, and its modification to a version suitable for resource-constrained settings were posed. While ceruloplasmin and 24-h urine copper continue to be important, there is little role of serum copper and penicillamine challenge test in the diagnostic algorithm. A new scoring system - Modified Leipzig score has been suggested with extra points being added for family history and serum ceruloplasmin lower than 5 mg/dl. Liver dry copper estimation and penicillamine challenge test have been removed from the scoring system. Differences in pharmacological approach to neurological and hepatic disease and global monitoring scales have been included. Rising bilirubin and worsening encephalopathy are suggested as indicators predicting need for liver transplant but need to be validated. The clinical practice guidelines provide recommendations for a comprehensive management of WD which will be of value to all specialties.

Abstract
Wilson disease (WD) is a potentially treatable, inherited disorder of copper metabolism that is characterized by the pathological accumulation of copper. WD is caused by mutations in ATP7B, which encodes a transmembrane copper-transporting ATPase, leading to impaired copper homeostasis and copper overload in the liver, brain and other organs. The clinical course of WD can vary in the type and severity of symptoms, but progressive liver disease is a common feature. Patients can also present with neurological disorders and psychiatric symptoms. WD is diagnosed using diagnostic algorithms that incorporate clinical symptoms and signs, measures of copper metabolism and DNA analysis of ATP7B. Available treatments include chelation therapy and zinc salts, which reverse copper overload by different mechanisms. Additionally, liver transplantation is indicated in selected cases. New agents, such as tetrathiomolybdate salts, are currently being investigated in clinical trials, and genetic therapies are being tested in animal models. With early diagnosis and treatment, the prognosis is good; however, an important issue is diagnosing patients before the onset of serious symptoms. Advances in screening for WD may therefore bring earlier diagnosis and improvements for patients with WD.

Abstract
Liver transplantation (LT) is a rescue therapy for life-threatening complications of Wilson's disease (WD). However, data on the outcome of WD patients after LT are scarce. The aim of our study was to analyze a large pediatric WD cohort with the aim of investigating the longterm outcome of pediatric WD patients after LT and to identify predictive factors for patient and transplant survival. This is a retrospective cohort study using data of all children (<18 years) transplanted for WD enrolled in the European Liver Transplant Registry from January 1968 until December 2013. In total, 338 patients (57.6% female) transplanted at 80 different European centers (1-26 patients per center) were included in this study. The median age at transplantation was 14.0 years (interquartile range [IQR], 11.2-16.1 years); patients were followed up for a median of 5.4 years (IQR, 1.0-10.9 years) after LT. Overall patient survival rates were high with 87% (1-year survival), 84% (5-year survival), and 81% (10-year survival); survival rates increased considerably with the calendar year (P < 0.001). Early age at LT, living donation, and histidine tryptophan ketoglutarate preservation liquid were identified as risk factors for poor patient survival in the multivariate analysis. LT is an excellent treatment option for pediatric patients with WD and associated end-stage liver disease. Longterm outcome in these patients is similar to other pediatric causes for LT. Overall patient and graft survival rates improved considerably over the last decades. To improve future research in the field, the vast variability of allocation strategies should be harmonized and a generally accepted definition or discrimination of acute versus chronic WD needs to be found.

Abstract
BACKGROUND Clinical presentations of Wilson's disease (WD) in childhood ranges from asymptomatic liver disease to cirrhosis or acute liver failure, whereas neurological and psychiatric symptoms are rare. The basic diagnostic approach includes serum ceruloplasmin and 24-hour urinary copper excretion. Final diagnosis of WD can be established using a diagnostic scoring system based on symptoms, biochemical tests assessing copper metabolism, and molecular analysis of mutations in the ATP7B gene. Pharmacological treatment is life-long and aims at removal of copper excess by chelating agents as D-penicillamine, trientine, or inhibition of intestinal copper absorption with zinc salts. Acute liver failure often requires liver transplantation. This publication aims to provide recommendations for diagnosis, treatment, and follow-up of WD in children. METHODS Questions addressing the diagnosis, treatment, and follow-up of WD in children were formulated by a core group of ESPGHAN members. A systematic literature search on WD using MEDLINE, EMBASE, Cochrane Database from 1990 to 2016 was performed focusing on prospective and retrospective studies in children. Quality of evidence was assessed according to the GRADE system. Expert opinion supported recommendations where the evidence was regarded as weak. The ESPGHAN core group and ESPGHAN Hepatology Committee members voted on each recommendation, using the nominal voting technique.

Abstract
BACKGROUND Experience with zinc in treating symptomatic hepatic Wilson's disease (WD) is limited. AIM To study the efficacy of Penicillamine followed by zinc in treating symptomatic hepatic Wilson's disease. METHODS We retrospectively analyzed case records of 31 symptomatic hepatic WD patients for whom disease severity scores (Child's, model for end-stage liver disease (MELD), Nazer's, and New Wilson Index (NWI) score) and 24-h urinary copper were compared at 3-time points-baseline at presentation, at transition from penicillamine to zinc and at end of follow up. RESULTS Thirty-one patients (median age 11 [5-24] years) with symptomatic hepatic WD were studied; ten had associated neuropsychiatric manifestations of WD. Penicillamine was changed to zinc sulfate either due to financial constraints (28 patients) or due to adverse effects of penicillamine (3 patients). At presentation (baseline), six patients belonged to Child's class A, five to Child's B, and 17 to Child's C. Duration of initial penicillamine chelation therapy was 134 (2-320) weeks, and of subsequent zinc therapy was 363 (35-728) weeks. There was a significant improvement in liver function tests and disease severity scores (Child's, MELD, Nazer's, and NWI score) at the transition from penicillamine to zinc compared to baseline. This improvement was maintained until the end of study period with 90% survival at 10 (2-20) years. Fifteen of the 17 Child's C cirrhotic patients showed significant improvement in disease severity scores from baseline until end of follow up. CONCLUSIONS Penicillamine followed by zinc may be a safe and effective treatment in resource-constrained setting for symptomatic hepatic WD patients in all grades of baseline disease severity. Some patients with decompensated cirrhosis due to WD may be managed with medical treatment, avoiding liver transplantation.

Abstract
Wilson's disease (WD) is a rare autosomal recessive disorder characterized by abnormal copper accumulation. Presenting a broad variety of phenotypes and, thus, being a chameleon within the group of metabolic diseases, the manifold clinical symptoms of WD can include hepatologic, neurologic, and psychiatric manifestations. Early onset presentations in infancy and late-onset manifestations in adults older than 70 years of age have been described. If the typical laboratory blood test values are missing, the diagnosis of WD may be difficult and often involves a combination of different parameters. Novel test methods like the identification of the relative exchangeable copper have not been validated within a sufficient cohort of WD patients as of yet and therefore do not currently play a crucial role within the clinical setting. Consequently any patient with reasonable suspected diagnosis of WD needs to be presented to a (pediatric) gastroenterologist and/or (pediatric) neurologist. Different medical treatments including drugs such as copper chelating agents are commonly used in the clinical setting. Liver transplantation may be the ultima ratio in selected patients. Dietary changes involving a low copper diet play only a minor role. Due to the fact the use of tetrathiomolybdate is still not approved, the treatment of advanced and progressive neurologic symptoms remains a major challenge. In any case, life-long medical supervision and treatment governed by a specialist is absolutely essential. Early diagnosis and early and life-long treatment lead to better prognoses and do not negatively influence the overall life expectancy.

Abstract
Wilson's disease is a rare, inherited autosomal recessive disease of copper metabolism, in which the causative gene, ATP7B, results in absent or reduced function of the ATP7B transporter important for biliary excretion of copper and incorporation of copper into caeruloplasmin. Affected patients accumulate excessive copper within the liver, brain and other tissues. A disease mainly of children, adolescents and young adults; clinical features vary from the asymptomatic state to chronic liver disease, acute liver failure, and neuropsychiatric manifestations. Diagnosis requires a high index of suspicion and is based on a combination of clinical signs, biochemical tests, hepatic copper content assay and mutation analysis of the ATP7B gene; to date, there are more than 500 mutations of ATP7B in patients with Wilson's disease. Early recognition and treatment can result in an excellent prognosis whereas untreated disease is almost always fatal. Drug therapies include chelating agents, such as penicillamine or trientine, and zinc salts. Liver transplantation is curative correcting the underlying pathophysiology and is traditionally indicated in acute liver failure or end-stage liver disease refractory to medical therapy. This review provides an overview of various aspects of Wilson's disease including molecular basis of the disease, clinical features, diagnostic and management strategies with their current limitations.

Abstract
Background Wilson’s disease (WD) is an autosomal recessive disorder of copper metabolism resulting in multifaceted neurological, hepatic, and psychiatric symptoms. The objective of the study was to comparatively assess two clinical rating scales for WD, the Unified Wilson’s Disease Rating Scale (UWDRS) and the Global Assessment Scale for Wilson’s disease (GAS for WD), and to test the feasibility of the patient reported part of the UWDRS neurological subscale (termed the “minimal UWDRS”). Methods In this prospective, monocentric, cross-sectional study, 65 patients (median age 35 [range: 15–62] years; 33 female, 32 male) with treated WD were scored according to the two rating scales. Results The UWDRS neurological subscore correlated with the GAS for WD Tier 2 score (r = 0.80; p < 0.001). Correlations of the UWDRS hepatic subscore and the GAS for WD Tier 1 score with both the Model for End Stage Liver Disease (MELD) score (r = 0.44/r = 0.28; p < 0.001/p = 0.027) and the Child-Pugh score (r = 0.32/r = 0.12; p = 0.015/p = 0.376) were weak. The “minimal UWDRS” score significantly correlated with the UWDRS total score (r = 0.86), the UWDRS neurological subscore (r = 0.89), and the GAS for WD Tier 2 score (r = 0.86). Conclusions The UWDRS neurological and psychiatric subscales and the GAS for WD Tier 2 score are valuable tools for the clinical assessment of WD patients. The “minimal UWDRS” is a practical prescreening tool outside scientific trials.

Abstract
Wilson's disease is an autosomal recessive disorder of copper metabolism, whose prevalence in the general population is 1/30000. Common manifestations are hepatic and neuropsychiatric, and in children, hepatic symptoms are most common. Copper chelating agents are effective in most cases, except for those who suffer from decompensated cirrhosis or fulminant liver disease. Liver transplantation, especially liver related living transplantation that has confirmed to be an effective method, has increasingly become a main method for treating children with late stage Wilson's disease.

Abstract
In Wilson disease (WD) defective AT7B function leads to biliary copper excretion and pathologic copper accumulation, particularly in liver and brain, where it induces cellular damage. Liver disease most often precedes neurologic or psychiatric manifestations. In most patients with neurologic or psychiatric symptoms there is some degree of liver disease at the time of disease presentation. Hepatic manifestations of WD can be extremely variable. Patients with clinically asymptomatic WD are often found by family screening or identified on routine laboratory testing. Others may have a clinical picture of chronic active hepatitis or of end-stage liver disease with cirrhosis. A minority present with acute liver failure, often on the background of advanced fibrosis. Complications from liver disease may be related to portal hypertension and concomitant liver disease may accelerate the course of liver disease. Liver cancer may occur in patients with WD, most commonly when cirrhosis and inflammation are present. The prognosis of patients with WD is excellent, especially for those without cirrhosis at the time of diagnosis, but requires timely initiation of appropriate therapy specific for WD and for the patient's liver disease independent of WD.

Abstract
Clinical presentation of Wilson disease can vary widely; therefore diagnosis is not always straightforward. Wilson disease is not just a disease of children and young adults, but may present at any age. The key features of Wilson disease are liver disease and cirrhosis, neuropsychiatric disturbances, Kayser-Fleischer rings, and acute episodes of hemolysis, often in association with acute liver failure. Diagnosis is particularly difficult in children and in adults presenting with active liver disease. None of the available laboratory tests is perfect and may not be specific for Wilson disease. A detailed neurologic examination is required for all cases. Neuroimaging and electrophysiologic methods are helpful. To overcome the diagnostic challenge, several clinical signs (Kayser-Fleischer rings, neurologic symptoms) and laboratory features (copper in serum, urine, liver; serum ceruloplasmin; genetic testing) are scored 0 (absent) to 2 (present) and the Leipzig score is calculated. If the score is ≥4, the diagnosis of Wilson disease is very likely. For asymptomatic siblings of index patients, mutation analysis is the most reliable approach.

Abstract
Liver transplantation (LT) is a life-saving and curative treatment for Wilson disease (WD), providing restoration of function of the liver and mitigation of portal hypertension. Indications for LT in patients with WD include acute liver failure or end-stage liver disease not treatable by medical therapy. LT is also used to treat hepatocellular carcinoma when it develops in patients with WD when tumor resection is not feasible. LT solely for neurologic or psychiatric WD remains controversial. Living liver donation as well as cadaveric orthotopic and auxiliary LT are options for transplantation for WD. Outcomes for LT for WD are excellent, and supportive measures while awaiting transplantation help bridge the patient to a more successful outcome. Future hepatocyte or stem cell transplantation may augment or supplant current LT for WD.

Abstract
Liver transplantation (LT) is the only proven treatment for pediatric acute liver failure (PALF). However, over a period of time, spontaneous native liver survival is increasingly reported, making us wonder if we are overtransplanting children with acute liver failure (ALF). An effective prognostic model for PALF would help direct appropriate organ allocation. Only patients who would die would undergo LT, and those who would spontaneously recover would avoid unnecessary LT. Deriving and validating such a model for PALF, however, encompasses numerous challenges. In particular, the heterogeneity of age and etiology in PALF, as well as a lack of understanding of the natural history of the disease, contributed by the availability of LT has led to difficulties in prognostic model development. Several prognostic laboratory variables have been identified, and the incorporation of these variables into scoring systems has been attempted. A reliable targeted prognostic model for ALF in Wilson's disease has been established and externally validated. The roles of physiological, immunological, and metabolomic parameters in prognosis are being investigated. This review discusses the challenges with prognostic modeling in PALF and describes predictive methods that are currently available and in development for the future.

Abstract
Although Wilsons's disease (WD) may be treated with copper chelation (to remove copper) or zinc salts (to prevent absorption) to alleviate or prevent symptom development in most patients, there are WD patients for whom medical therapy is inadequate and survival would be unlikely without liver transplantation. Liver transplantation is indicated for the ∼5% of WD patients with acute liver failure as the first presentation of disease, most commonly in the second decade of life, or those who present with end-stage liver disease and severe hepatic insufficiency, most commonly in the third and fourth decades. Liver transplantation restores normal biliary copper excretion (thereby preventing disease recurrence) and promotes removal of copper from extrahepatic sites. Outcomes of liver transplantation for WD are excellent, including both cadaveric and living donors.

Abstract
Fulminant Wilson's disease (WD) is life-threatening. The revised WD prognostic index (RWPI) has been used to predict the severity of the disease, with a score ≥11 indicating fatal outcome without liver transplantation (LTx). We here report the case of a 10-year-old female patient with fulminant WD (RWPI, 16) who recovered fully after plasma exchange and continuous hemodiafiltration, followed by treatment with copper chelate agents. To the best of our knowledge, there have been five fulminant WD patients with RWPI ≥ 11 including the present patient, in whom LTx was not done. Based on the therapeutic modalities in these five cases, non-surgical treatment (blood purification and copper chelate agents) may be able to avoid LTx in fulminant WD even with very high RWPI, although preparation for LTx is necessary.

Abstract
BACKGROUND AND AIMS Wilson disease (WD) associated acute liver failure (ALF) affects children more than adults. The predictors of mortality and outcome in patients without encephalopathy are not clear. We investigated the ability of prognostic factors and various models including model for end-stage liver disease (MELD) to predict mortality among children with WD and ALF. METHODS We analyzed the admission characteristics in 61 children <18 years with WD and ALF. Factors associated with mortality on univariate Cox regression analysis were analyzed by forward stepwise Cox hazards regression. The prognostic models such as Nazer's model, revised Kings College Model, and pediatric end-stage liver disease/model for end-stage liver disease (PELD/MELD) score were compared. RESULTS Of the 145 children < 18 years with WD, 61 experienced ALF of whom 33 (54%) died, including 22/27 (81.5%) with encephalopathy and 11/34 (32.4%) without encephalopathy. The mean age of children with ALF was 9.7 years, 38(62.3%) were boys. Prognostic factors significant for mortality included encephalopathy, international normalized ratio, total proteins, total and direct bilirubin, alkaline phosphatase, serum creatinine, and white blood cell count. Forward stepwise Cox proportional hazards regression identified encephalopathy (hazard ratio 2.88; CI 1.1-7.4) and total bilirubin (hazard ratio 1.05; CI: 1.02-1.09) as predictors of outcome. The area under the receiver operating curve (AUC) of the Nazer index, revised King's College Criteria, and PELD/MELD were 0.74, 0.76, and 0.75, respectively. CONCLUSIONS Mortality in children with WD and ALF is 54% including 81.5% with encephalopathy and 32.4% without encephalopathy. The prognostic models, MELD/PELD score, Nazer index and Kings College Criteria are comparable with a AUC between 0.74-0.76.
