Abstract
BACKGROUND & AIMS Wilson disease (WD) is a rare hereditary, debilitating disease that is fatal if untreated. Given its low prevalence, collecting longitudinal information on large cohorts of patients is challenging. Analysis of health insurance databases offers an approach to meet this challenge. The aim of this study was to evaluate longitudinal trends in the presentation and management of patients with WD identified in the French national health insurance database (SNDS). METHODS This retrospective, longitudinal, observational study identified people with WD in the SNDS database through hospitalisation diagnosis codes and long-term illness status between 2009 and 2019 inclusive. For each patient, data were extracted on hospitalisations, liver transplantation, mortality, WD-specific treatments (d-penicillamine, trientine and zinc), disability status and sick leave. RESULTS 1,928 patients with WD were identified, of whom 1,520 (78.8%) were analysed. Prevalence of WD in 2019 was estimated as 2.2 cases per 100,000. Of the 670 patients first documented between 2010 and 2019, 76.1% were hospitalised at least once for a mean duration of 4.63±10.6 days. 152 patients (10.0%) underwent liver transplantation and 205 died (13.5%). The mean age at death was 57.9 ± 23.1 years. 665 patients (43.8%) received a WD-specific treatment at least once. 167 patients (17.1%) received a government disability pension and 624 (41.1%) benefited from long-term illness status due to WD. CONCLUSIONS Unexpectedly, less than half of patients with WD received treatment recommended in practice guidelines, which may contribute to a high disease burden in terms of hospitalisations, disability and reduced life expectancy. Improving treatment rates, building patient awareness of long-term disease impact or developing a new paradigm of treatment could make a significant contribution to reducing the disease burden.

Biomolecules 2022; 12:biom12121791. [PMID: 36551217 PMCID: PMC9775970 DOI: 10.3390/biom12121791] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 11/24/2022] [Accepted: 11/26/2022] [Indexed: 12/02/2022] Open
Abstract
The aim of this study was to demonstrate that pseudocholinesterase (CHE) serum level is a useful diagnostic biomarker for untreated Wilson's disease (WD). Between 2013 and 2019, about 75 patients were referred to the outpatient department of the University of Düsseldorf with suspected Wilson's disease. In 31 patients with suspected Wilson's disease (WD-SUS-group), WD was excluded by means of investigations other than analysis of blood and urine. A total of 27 parameters of blood and urine in these 31 patients were compared to those of 20 de novo patients with manifest WD (WD-DEF-group), which parameter showed the highest significance level of difference between the WD-DEF-group and the WD-SUS-group. Thereafter, receiver operating characteristics (ROC-curves) were analyzed to evaluate which parameter showed the largest area under the curve (AUC) to detect WD. Finally, a logistic regression analysis was performed to analyze which combination of parameters allowed the best classification of the 51 patients either into the WD-DEF-group or into the WD-SUS-group. CHE showed the highest significance level for a difference between the WD-DEF- and WD-SUS-group, had the highest AUC, and, in combination with ceruloplasmin, allowed 100% correct classification. Without CHE, no other combination of parameters reached this level of correct classification. After the initiation of treatment, which regularly results in an improvement in CHE, the high diagnostic accuracy of this biomarker was lost. Cholinesterase turns out to be an excellent biomarker for differentiation between untreated de novo patients with manifest WD and heterozygotic gene carriers.

Abstract
Abstract
Background
Wilson disease (WD) is an inherited disorder of copper metabolism commonly involving the liver, cornea, and brain. Its incidence is increasing day by day worldwide. Early diagnosis and prompt treatment are the key for best outcome.
Material and methods
A cross-sectional descriptive study was done from January 2014 to December 2019. Sixty children of both genders between 3 and 18 years were diagnosed by clinical and laboratory profile meeting selected criteria.
Results
Mean age was 8.42 ± 2.6 years and male female ratio was 1.5:1. Consanguinity of marriage was found in 38.3% cases. Seventy percent of cases were hepatic, 16.7% were neuropsychiatric, 5.0% were hepatic with neuropsychiatric, and 8.3% cases were manifested asymptomatically. Asymptomatic and hepatic WD were reported between 3 and 10 years and most of the neuropsychiatric and hepatic with neuropsychiatric manifested after 10 years of age. More than 50% cases improved, a little more than 20% children died, 18.4% were unchanged and 6.6% were hepatic added neuropsychiatric manifestations. Most of the asymptomatic (100%) and hepatic (61.9%) cases improved. High mortality was found with 76.9% cases of acute liver failure (ALF), 7.7% case of chronic liver disease (CLD) and 25% cases of CLD with portal hypertension (CLD and PH). Most of the neuropsychiatric cases (90.0%), and approximately two-third (66.6%) of hepatic with neuropsychiatric cases remained unchanged. Neuropsychiatric manifestations were added in 15.4% cases of CLD and 25% cases of CLD with PH patient. The treatment was well tolerated in 66% children without any side effects. Low WBC (6.3%) and platelet count (4.3%), vomiting (6.3%), anorexia (4.3%), loss of taste (4.3%), rash (4.3%), and proteinuria (2.1%) were found in few cases.
Conclusion
Majority of the children were presented with hepatic manifestations. More than half of patients with WD treated by D-penicillamine (DP) were improved. Significant mortality was found in acute liver failure whereas neuropsychiatric presentations had persistent abnormalities. No major side effects of DP was observed in most of the cases. Early diagnosis and prompt treatment were crucial for better outcome.

Abstract
Copper is an essential trace element in an organism, and changes in copper levels in vivo often indicate a diseased state. Copper and immunity have been discussed since the last century, with copper deficiency significantly affecting the development and function of the immune system, such as increased host susceptibility to various pathogens, decreased number and impaired function of neutrophils, reduced antibacterial activity of macrophages, decreased proliferation of splenocytes, impaired B cell ability to produce antibodies and impaired function of cytotoxic T lymphocyte and helper T cells. In the past 20 years, some studies have shown that copper ions are related to the development of many tumors, including lung cancer, acute lymphoid leukaemia, multiple myeloma and other tumors, wherein copper ion levels were significantly elevated, and current studies reveal that copper ions are involved in the development, growth and metastasis of tumors through various pathways. Moreover, recent studies have shown that copper ions can regulate the expression of PD-L1, thus, attention should be paid to the important role of copper in tumor immunity. By exploring and studying copper ions and tumor immunity, new insights into tumor immunity could be generated and novel therapeutic approaches to improve the clinical prognosis of patients can be provided.

Abstract
BACKGROUND Single daily dose (SDD) is a good way to improve adherence by simplifying treatment. Efficacy data concerning patients with Wilson disease (WD) taking an SDD are lacking. AIM To report the effectiveness of the use of SDD for the treatment of WD. METHODS This retrospective study included WD patients followed in the French National Network who received an SDD in maintenance phase. The treatment failure was defined as a composite criterion with the occurrence of at least one of the following criterion: death, transplantation, increase of transaminases >2xULN, hepatic decompensation, neurological aggravation, severe side effects related to treatment, and/or discontinuation of treatment. RESULTS A total of 26 patients received an SDD (D-penicillamine=13, trientine=8, zinc=5) after a median interval of 152 months after diagnosis. After one year, two patients had treatment failure: transaminitis in one, continuation of neurological deterioration in the other related to a poor compliance. After a median duration of 41 months on SDD, 3 other patients had treatment failure (transaminitis=2, treatment discontinuation=1). There was no death, no liver transplantation, no hepatic decompensation, and no severe side effects related to treatment during the follow-up. Moreover, transaminases and serum exchangeable copper were not significantly different 1 year post-switch and at last follow-up compared to baseline. CONCLUSIONS Maintenance therapy simplification through the use of an SDD could be considered in some WD patients. In this pilot study, SDD was effective in 21/26 patients (81%) without any concern regarding safety.

Abstract
BACKGROUND AND OBJECTIVES Wilson's disease (WD) is an inherited disorder with perturbations in copper metabolism and can cause multiorgan damage. This study aims to explore cardiac findings mainly based on electrocardiography (ECG) in WD patients. METHODS We retrospectively enrolled adult patients who were diagnosed with WD between January 2011 and December 2020. Demographic and clinical data were collected and reevaluated. RESULTS A total of 126 patients were included. There were 71 men and 55 women. The mean age was 27.2 years. Ninety-nine had hepatic presentation as the initial symptom and 27 had neuropsychiatric presentation as the initial symptom. Thirty-seven patients (29.4%) had cardiac manifestations. Of these patients, nine presented apparent cardiac symptoms (three with discontinuous chest tightness, three with dizziness, two with palpitation and one with atypical chest pain) and 28 had asymptomatic electrocardiography (ECG) abnormalities. Among the nine patients, four had second- or third-degree atrioventricular block, three had ST-segment change and two had ventricular tachycardia. ECG abnormalities in the 28 patients included increase in the width of the QRS complex in 8, atrial premature beats in 8, T-wave inversion in 5, P-wave inversion in 2, sinus bradycardia in 2, ST-segment change in 2, and coexistence of sinus bradycardia and T-wave inversion in 1. No statistical difference (P = 0.32) existed in the occurrence of ECG abnormalities between patients with hepatic presentation (27/99) and those with neuropsychiatric presentation (10/27). CONCLUSION Cardiac involvement is not rare in adult WD patients. We suggest that cardiac evaluation should be routinely performed in the population.

Abstract
OBJECTIVES Wilson disease is an inherited disorder that results in copper accumulation in the tissues with liver injury and failure. Orthotopic liver transplant is one of the treatments of choice for this disease. The aim of this study was to compare the neurological symptoms, before and after orthotopic livertransplant, of patients with liver cirrhosis due to Wilson disease, who represent a special group of patients with liver failure. MATERIALS AND METHODS Between 2007 and 2020, there were 24 patients with Wilson disease resistant to medical treatment who underwent deceased donor orthotopic livertransplant and were followed up for 1 year, 5 years, and 10 years for evaluation with neurological scoring systems. Patients were also evaluated for postoperative complications and survival. RESULTS Of the 24 patients evaluated, there were 13 (54.2%) female patients and 11 (45.8%) male patients, and the mean age was 34 years (range, 14-57 years). One of the patients died from early postoperative sepsis. After orthotopic livertransplant, disease scores returned to normal in 16 patients and improved in the remaining patients. Before transplant, all patients required help in their daily activities. After transplant, there were significant improvements in some symptoms, and the patients became more independent in their daily lives. CONCLUSIONS Our study shows that orthotopic liver transplant provides significant improvement in neurological symptoms and quality of life in patients with Wilson disease.

Abstract
BACKGROUND Wilson's disease (WD) is an autosomal recessive inherited disorder of copper metabolism resulting from various mutations in the ATP7B gene. Despite good knowledge and successful treatment options, WD is a severe disease that leads to disability, destructively affecting the quality of life of patients. Currently, none of the available laboratory tests can be considered universal and specific for the diagnosis of WD. Therefore, the introduction of genetic diagnostic methods that allow for the identification of the root cause at any stage over the course of the disease gave hope for an earlier solution of diagnostic issues in patients with WD. METHODS A method for the genetic diagnosis of WD based on ARMS PCR, DreamTaq Green PCR Master Mix and modified primers has been developed. This method is able to detect 14 mutant alleles: p.His1069Gln, p.Glu1064Lys, p.Met769HisfsTer26, p.Gly710Ser, p.Ser744Pro, p.Ala1135GlnfsTer13, p.Arg778Leu, p.Arg1041Trp, p.Arg616Gln, p.Arg778Gly, p.Trp779*, p.Val834Asp, p.Gly943Ser and p.3222_3243+21del43. RESULTS The primers for all mutations were highly specific with an absence of wild-type amplification. All the results were validated by direct DNA Sanger sequencing. CONCLUSIONS This fast and economical method provides coverage for the identified common mutations, thereby making ARMS PCR analysis using DreamTaq Green PCR Master Mix and modified primers feasible and attractive for large-scale routine use.

Abstract
OBJECTIVES Determining 24-hour urinary copper excretion (UCE) levels is useful for diagnosing Wilson's disease (WD) and for treatment monitoring. Exchangeable copper (ExC) is a novel potential marker, but its long-term changes have never been described in patients under chelation therapy. Our aim was to describe the long-term changes in ExC levels compared to UCE levels in symptomatic WD pediatric patients under chelation therapy. METHODS A retrospective, descriptive, and analytical study including all patients under 18 years of age, diagnosed between 2006 and 2020, and treated with chelation therapy was conducted at the National Reference Center for WD in Lyon. Ceruloplasmin levels, serum copper, 24 h-UCE, ExC, and liver enzymes at diagnosis and during follow-up were analyzed. RESULTS Our study included 36 patients, predominantly with hepatic form of WD (n = 31). The median [interquartile range (IQR)] age at diagnosis was 10.5 (8.4-13.1) years, and the median (IQR) follow-up duration was 6.3 (3.3-8.8) years. At diagnosis, the median (IQR) ExC value was 1.01 (0.60-1.52) µmol/L. There was a significant decrease during the first year of chelation treatment ( P = 0.0008), then a stabilization. The median (IQR) ExC values was 0.38 (0.22-0.63) µmol/L at 12-18 months and 0.43 (0.31-0.54) µmol/L at 5 years of chelation treatment ( P = 0.4057). Similarly, there was a significant decrease in 24-hour UCE ( P < 0.001) during the first year of chelation treatment, then a stabilization. CONCLUSIONS Our study showed a significant decrease in ExC and 24-hour UCE levels during the first year of follow-up; The dynamics of both biomarkers were similar along the follow-up, demonstrating their usefulness in clinical practice for monitoring WD.

Abstract
OBJECTIVES Wilson disease (WD) is a rare autosomal recessive disease caused by an ATP7B gene mutation. Liver cirrhosis is an important issue that affects the clinical management and prognosis of WD patients. Blood routine examination is a potential biomarker for predicting the occurrence of liver cirrhosis in WD. We aim to construct a predictive model for the occurrence of liver cirrhosis using general clinical information, blood routine examination, urine copper, and serum ceruloplasmin through a machine learning approach. METHODS Case-control study of WD patients admitted to West China Fourth Hospital between 2005 and 2020. Patients with a score of at least four in scoring system of WD were enrolled. A machine learning model was constructed by EmpowerStats software according to the general clinical data, blood routine examination, 24 h urinary copper, and serum ceruloplasmin. RESULTS This study analyzed 346 WD patients, of which 246 were without liver cirrhosis. And we found platelet large cell count (P-LCC), red cell distribution width CV (RDW-CV), serum ceruloplasmin, age at diagnosis, and mean corpuscular volume (MCV) were the top five important predictors. Moreover, the model was of high accuracy, with an area under the receiver operating characteristic curve of 0.9998 in the training set and 0.7873 in the testing set. CONCLUSIONS In conclusion, the predictive model for predicting liver cirrhosis in WD, constructed by machine learning, had a higher accuracy. And the most important indices in the predictive model were P-LCC, RDW-CV, serum ceruloplasmin, age at diagnosis, and MCV.

Abstract
Objectives Wilson's disease (WD) is an autosomal recessively inherited disorder with a reported prevalence of 33-68/100,000 in Asian countries not including India. There is a paucity of research in India on prevalence, pattern, and profile of neuropsychological deficits among these patients. The objectives of the study were to profile neuropsychological differences between patients with WD and age- and education-matched healthy controls. Material and Methods A hospital-based, cross-sectional, and comparative study using strategic combination of neuropsychological tests. Persons with neurological WD receiving IP care over a 3-month period were compared with matched controls. The inclusion criteria were diagnoses of Chu Stage 1 and Chu Stage 2 neurological WD, age 15-45 years, illness of minimum 6 months, and diagnosis confirmed by low serum ceruloplasmin. Exclusion criteria were evidence or clinical suspicion of intellectual disability and past or current psychiatric illness. Results Median age of patients - 17.5, median age of controls - 18. R software was used to analyze the results. For all cases and controls, time taken to administer the set of tests was always <30 min. Non-parametric tests were chosen considering the data distribution. Statistically significant differences with P < 0.05 are noted in domains of processing speed, frontal executive function, focused attention, verbal, and visual memory in descending order. Conclusion A strategic compilation of easily performed bedside neuropsychological tests demonstrated differences between the two groups. This combination can be rapidly administered in the clinical setting and hence improve change tracking. This may aid in early identification and hence, earlier initiation of therapy with a possibility of improved clinical outcomes.

Abstract
OBJECTIVES To evaluate and compare pregnancy outcomes in women with Wilson's disease (WD) undergoing different therapies during pregnancy. MATERIAL AND METHODS Retrospective review of medication in WD patients during pregnancy and the outcomes. RESULTS Of 26 pregnancies, zinc was used in 14 (53.8%), D-penicillamine in 4 (15.4%) patients, and 8 (30.8%) were untreated. Spontaneous abortion was observed in 8 (30.8%) pregnancies - untreated patients (4/8 pregnancies), zinc (2/14 pregnancies) and D-penicillamine (2/4 pregnancies) -, healthy outcome in 12 (46.1%) and birth defects in 6 (23.1%). All cases of birth defects occurred in patients using zinc therapy (6/14 pregnancies). CONCLUSIONS A remarkably high frequency of fetal complications shed lights on the potentially harmful effect of WD drugs during childbearing age. Zinc's safety profile may have to be better evaluated during pregnancy, as all of birth defects occurred with zinc therapy.

Abstract
Background Neurological Wilson's disease (WD) presentation in the pediatric population is rare, and liver transplantation (LT) in these patients remains controversial. The aim of the present study was to assess the role of brain magnetic resonance imaging (MRI) in predicting reversion of brain lesions and neurological outcomes in pediatric WD patients after LT. Methods Patients with confirmed WD (Leipzig score ≥4), disease onset in pediatric age (<18 years), neurological involvement, and submitted to LT were selected. Clinical records and pre- and post-LT brain MRI were evaluated. Results Six patients met the pre-defined inclusion criteria, one of whom died shortly after LT and was excluded. The indication for LT was end-stage liver disease in two patients and neurological worsening despite optimized treatment in three patients. After LT, the neurological picture progressively improved in all patients. Pre-LT brain MRI showed T1-weighted hyperintensities in four patients, which quickly resolved afterward. T2-weighted hyperintensities were observed in four patients before LT, completely resolving in one patient, stabilizing in two, and improving in one after LT. A direct correlation could not be found between clinical and neuroradiological improvement. Progressive clinical improvement was observed even in patients with irreversible brain MRI changes. Conversely, some patients with normal MRI had only slight neurological improvement. Conclusions The pattern of T2-weighted hyperintensities after LT was unpredictable and did not correlate with neurological outcomes, suggesting that these changes may not entail irreversible clinical damage. Therefore, brain MRI does not seem to have prognostic value for assessing clinical response to LT.

Abstract
Wilson disease is an inherited disorder of copper metabolism with an autosomal recessive inheritance pattern (hepatolenticular degeneration). In this case, a 13-year-old child was seen with overall exhaustion, sporadic abdominal discomfort, and shrinking handwriting during the previous 12 months. On clinical examination there was hepatosplenomegaly. Routine blood work revealed anemia, leukopenia, thrombocytopenia, elevated total and indirect bilirubin, alkaline phosphatase and transaminitis. Serum ceruloplasmin is decreased, urine copper excretion is increased. Slit lamp examination revealed Kayser-Fleischer rings in both eyes. Ultrasonography (USG) abdomen confirmed hepatosplenomegaly, coarse echotexture of the liver. MRI Brain revealed the bilateral and diffuse and symmetric hyperintensity of caudate and lentiform nuclei, which are consistent with the neuro-parenchymal changes of Wilson’s disease. We report this case due to its rare incidence and atypical presentation and to highlight the importance of clinical examination in reaching the diagnosis.

Abstract
Dacomitinib, the second-generation epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI), has been used as a first-line treatment in non-small cell lung cancer (NSCLC) patients harboring EGFR mutation. In this case, we report a patient with drug-induced liver injury (DILI) associated with the use of dacomitinib. A 59-year-old man with stage IV NSCLC was prescribed with dacomitinib; 37 days after dacomitinib administration, he was admitted to our hospital because of jaundice. Laboratory examinations revealed elevated serum levels of liver enzymes and bilirubin. Following the immediate discontinuation of dacomitinib, liver enzymes decreased but bilirubin continued to rise. Total bilirubin reached the peak (18-fold) on day 26 after dacomitinib termination and normalized on day 146 after dacomitinib discontinuation. A "probable" cause of DILI by dacomitinib was determined based on the Roussel Uclaf Causality Assessment Method. The severity of DILI was assessed as acute liver failure. To our knowledge, this is the first case of DILI caused by dacomitinib monotherapy in a real-world setting. Clinicians should pay particular attention to the possibility of DILI during dacomitinib treatment.

Abstract
Background In Wilson’s disease (WD), early neurological deterioration after treatment initiation is associated with poor outcomes; however, data on this phenomenon are limited. Our study analysed the frequency and risk factors of early neurological deterioration in WD. Methods Early neurological deterioration, within 6 months from diagnosis, was defined based on the Unified Wilson’s Disease Rating Scale (UWDRS): any increase in part II or an increase of ≥ 4 in part III. In total, 61 newly diagnosed WD patients were included. UWDRS scores, brain magnetic resonance imaging (MRI) scores, copper metabolism parameters, treatment type and serum neuro-filament light chain (sNfL) concentrations at diagnosis were analysed as potential risk factors of early deterioration. Results Early neurological deterioration was observed in 16.3% of all WD patients; all cases of worsening occurred in the neurological phenotype (27.7%). Higher scores were seen in those who deteriorated compared with those who did not for UWDRS part II (4.3 ± 5.0 vs 2.0 ± 5.9; p < 0.05), UWDRS part III (21.5 ± 14.1 vs 9.3 ± 16.4; p < 0.01) and MRI-assessed chronic damage (3.2 ± 1.6 vs 1.4 ± 2.2; p = 0.006); all these variables indicated the initial severity of neurological disease. Pre-treatment sNfL concentrations were significantly higher in patients who deteriorated compared with those who did not (33.2 ± 23.5 vs 27.6 ± 62.7 pg/mL; p < 0.01). In univariate logistic regression amongst all patients, chronic damage MRI scores, UWDRS part III scores and sNfL concentrations predicated early deterioration. In the neurological WD, only sNFL were a significant predictor. In bivariate logistic regression amongst all patients, sNfL remained the only significant predictor of deterioration when corrected for MRI scores. Conclusion sNfL concentrations are a promising biomarker of the risk of early neurological deterioration in WD.

ATP7B Genotype and Chronic Liver Disease Treatment Outcomes in Wilson Disease: Worse Survival With Loss-of-Function Variants. Clin Gastroenterol Hepatol 2022; 21:1323-1329.e4. [PMID: 36096368 DOI: 10.1016/j.cgh.2022.08.041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2021] [Revised: 08/22/2022] [Accepted: 08/27/2022] [Indexed: 02/07/2023]
Abstract
BACKGROUND AND AIMS Although a good genotype-phenotype correlation has not been established in Wilson disease (WD), patients with loss-of-function (LOF) ATP7B variants demonstrate different clinical and biochemical characteristics. We aim to describe long-term treatment outcomes in the chronic liver disease (CLD) phenotype and evaluate an association with LOF variants. METHODS This was a single-center retrospective review of WD patients with at least 1 variant in ATP7B. Demographic, biochemical, genetic, and clinical parameters were obtained. The composite clinical endpoint of liver transplantation or death was used for probands with CLD phenotype on chelators. RESULTS Of 117 patients with hepatic WD: 71 had CLD, 27 had fulminant hepatic failure requiring urgent liver transplantation, and 19 were diagnosed through family screening. Median age at diagnosis was 13.1 (interquartile range, 9.7-17.6) years. In total, 91 variants in ATP7B were identified in the study population. At least 1 LOF variant was present in 60 (51.3%) patients. During median follow-up of 10.7 (interquartile range, 6.7-18.9) years, 10 (14.1%) of the probands with CLD reached the composite endpoint. There was a worse transplant-free survival for patients prescribed chelation therapy in patients with at least 1 LOF variant (P = .03). CONCLUSIONS Patients with WD and CLD phenotype on chelators, who have at least 1 LOF variant in ATP7B, have a worse prognosis during long-term follow up. This subgroup of patients requires close monitoring for signs of progressive liver disease. Sequencing of ATP7B may be used in the diagnosis of WD, and in addition, it may provide useful prognostic information for patients with hepatic WD.

Abstract
Wilson’s disease (WD) is an inherited disorder of copper metabolism associated with mutations in ATP7B gene. We have shown that the administration of an adeno-associated vector (AAV) encoding a mini version of human ATP7B (VTX-801) provides long-term correction of copper metabolism in a murine WD model. In preparation of a future clinical trial, we have evaluated by positron emission tomography (PET) the value of 64Cu biodistribution, excretion pattern, and blood kinetics as pharmacodynamic biomarkers of VTX-801 effects. Six-week-old WD mice were injected intravenously with increasing doses of VTX-801 and 3 weeks or 3 months later with [64Cu]CuCl2. Untreated WD and wild-type (WT) mice were included as controls. Control WD mice showed increased hepatic 64Cu retention, reduced fecal excretion of the radiotracer, and altered 64Cu blood kinetics (BK) compared with WT mice. VTX-801 treatment in WD mice resulted in a significant reduction of hepatic 64Cu accumulation, the restoration of fecal 64Cu excretion, and the correction of 64Cu BK. This study showed that VTX-801 restores physiological copper metabolism in WD mice, confirming the mechanism of action of VTX-801, and demonstrated the translational potential of [64Cu]CuCl2-PET to explore VTX-801 pharmacodynamics in a minimally invasive and sensitive manner in WD patients.

Abstract
Background Huppke–Brendel (HB) syndrome is an autosomal recessive disease caused by variants in the SLC33A1 gene. Since 2012, less than ten patients have been reported, none survived year six. With neurologic involvement and ceruloplasmin deficiency, it may mimic Wilson disease (WD). Objectives and methods We report the first adult patient with HB. Results The patient suffered from moderate intellectual disability, partial hearing loss, spastic ataxia, hypotonia, and unilateral tremor of parkinsonian type. At age 29, she was diagnosed with WD based on neurology, elevated 24H urinary copper, low ceruloplasmin, and pathological 65Cu test. Approximately 25 years later, genetic testing did not support WD or aceruloplasminemia. Full genome sequencing revealed two likely pathogenic variants in SLC33A1 which combined with re-evaluation of neurologic symptoms and MRI suggested the diagnosis of HB. Conclusion Adult patients with HB exist and may be confused with WD. Low ceruloplasmin and the absence of ATP7B variants should raise suspicion.

Abstract
Symptoms of Wilson disease (WD) vary and additional factors such as autoimmunity may play an important role in WD pathogenesis. The presence of antinuclear antibodies (ANA), anti-neutrophil cytoplasmic antibodies, neuronal surface antibodies, and onconeural antibodies in WD was investigated using standardized indirect immunofluorescence assays and Western Blot analysis. The presence of all studied autoantibodies was higher in WD patients in comparison to healthy subjects, but there was no statistically significant difference in autoantibodies frequency according to disease manifestation. D-penicillamine treatment was associated with a higher presence of ANA than zinc sulfate but without an increase in autoimmune diseases rate.

Abstract
OBJECTIVES Trientine dihydrochloride (TETA-2HCl) has been used for the treatment of Wilson disease for over 30 years. The current study was designed to systematically evaluate existing data to further define the long-term outcome of the efficacy and tolerability of TETA-2HCl in Wilson disease patients. METHODS Medical records of 77 Wilson disease patients were reviewed to collect data on hepatic and neurologic symptoms, copper (Cu) homeostasis and adverse events. Data were collected for 48 months after initiation of TETA-2HCl after withdrawal of D-penicillamine treatment. RESULTS Mean duration of TETA-2HCl treatment was 8 years (range 5 months-32.5 years). Over the course of TETA-2HCl treatment, 35% of patients had no hepatic symptoms whereas in 49.4% of patients, hepatic symptoms improved. They remained unchanged in 10.4% of patients and worsened in 5.2% of patients. No patients progressed to acute hepatic failure or necessity of a liver transplant. During TETA-2HCl treatment, 46.7% of patients had no neurologic symptoms; in 14.3% of patients, neurologic symptoms improved whereas in 36.4% of patients, they remained stable and worsened in 2.6% of patients. During the evaluation period, 12 patients discontinued TETA-2HCl treatment due to: anemia ( N = 1), inadequate hepatic response ( N = 2), switch to zinc treatment ( N = 8) and patient's decision to withdraw from treatment ( N = 1). Treatment-emergent adverse events were reported by 24.7% of the patients of which gastrointestinal disorders (9.1%) and nervous system disorders (5.2%) were most reported. CONCLUSIONS TETA-2HCl is well-tolerated and effective in Wilson disease patients following the withdrawal of treatment with D-penicillamine. ClinicalTrials.govIdentifier : NCT02426905.

Abstract
Zinc inhibits intestinal copper uptake, an effect utilized for treating Wilson’s disease (WD). We used copper-64 (64Cu) PET/CT to examine how much four weeks of treatment with different zinc regimens reduced the hepatic 64Cu content after oral 64Cu administration and test if alternative regimens were noninferior to the standard regimen of zinc acetate 50 mg × 3 daily. Forty healthy persons were randomized to four different zinc protocols. The WD standard treatment zinc acetate 50 mg × 3 reduced the hepatic 64Cu content from 26.9 ± 7.5% to 13.3 ± 5.6% of the administered 64Cu. Zinc gluconate 50 mg × 3 was noninferior (P = 0.02) (35.8 ± 9.0% to 17.4 ± 7.5%). Zinc acetate 150 mg × 1 (33.1 ± 9.9% to 17.4 ± 7.5%) and zinc gluconate 150 mg × 1 (28.1 ± 6.7% to 22.0 ± 6.7%) were less effective. These effects were intra- and inter-individually highly variable, and 14% had no effect of any zinc regimen, which may explain disparities in zinc treatment efficacy in WD patients.

Abstract
BACKGROUND Wilson’s disease (WD) is a rare inherited disorder of copper metabolism. Treatment consists of chelating agents, but side effects are common. We describe a patient who developed colitis during trientine treatment leading to decompensation of liver cirrhosis.
CASE SUMMARY A healthy 51-year-old woman was diagnosed with liver cirrhosis due to decompensation with ascites. Etiologic evaluation raised suspicion of hereditary hemochromatosis because of compound heterozygosity HFE p.C282Y/p.H63D, and phlebotomy was started. Re-evaluation showed low ceruloplasmin, increased urinary copper excretion and the presence of Kayser-Fleischer rings. WD was confirmed by genetic analysis. Because of decompensated cirrhosis, she was referred for liver transplant evaluation. Simultaneously, treatment with trientine was initiated. Liver function initially stabilized, and the patient was not accepted for a liver transplant. Shortly after this, she developed severe hemorrhagic colitis, most probably a side effect of trientine. During that episode, she decompensated with hepatic encephalopathy. Because of a second decompensating event, she was accepted for liver transplantation, and an uneventful transplantation was carried out after clinical improvement of colitis.
CONCLUSION Despite WD being a rare disorder, it is important to consider because it can present with a plethora of symptoms from childhood to an elderly age. Colitis should be recognized as a serious adverse drug reaction to trientine treatment that can result in decompensated liver disease.

Abstract
Wilson’s disease (WD) is a rare, treatable genetic disorder with multi-organ symptoms related mainly to copper accumulation. Most patients become aware of the disease as young adults, thus knowledge on fertility, pregnancy course and outcome is very important both for patients and physicians. The aim of this study was to perform a systematic review and meta-analysis of pregnancy outcomes in women with WD. This systematic literature review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies were identified by searching the PubMed database (up to 12 January 2022) and by screening reference lists. We found 49 publications, including 13 retrospective studies and 36 series and case reports on pregnancy outcomes in WD patients. In total, descriptions of 449 pregnant women with 822 pregnancies were retrieved. Successful deliveries were achieved in 78.3% (644/822) of all pregnancies. Spontaneous abortions were observed in 21.7% (178/822) of pregnancies, more frequently in patients who were untreated 68.6% (96/140). Analyzing maternal outcome, 2.2% (18/822) of pregnancies were associated with the aggravation of neurological symptoms. Symptoms of hepatic deterioration were observed in 4.6% (38/822) of cases. These were usually transient and recovered after pregnancy; however, death due to liver failure was observed in 0.2% (2/822) of cases. Birth defects occurred in 4.7% (39/822) of pregnancies. The available meta-analysis showed statistically significant positive associations between anti-copper treatment and pregnancy outcome. Our results document the significance of anti-copper treatment as the main factor leading to successful pregnancy, as well as positive outcomes for women with WD.

Abstract
Wilson’s disease (WD) is a hereditary disorder of copper metabolism, producing abnormally high levels of non-ceruloplasmin-bound copper, the determinant of the pathogenic process causing brain and hepatic damage and dysfunction. Although the disease is invariably fatal without medication, it is treatable and many of its adverse effects are reversible. Diagnosis is difficult due to the large range and severity of symptoms. A high index of suspicion is required as patients may have only a few of the many possible biomarkers. The genetic prevalence of ATP7B variants indicates higher rates in the population than are currently diagnosed. Treatments have evolved from chelators that reduce stored copper to zinc, which reduces the toxic levels of circulating non-ceruloplasmin-bound copper. Zinc induces intestinal metallothionein, which blocks copper absorption and increases excretion in the stools, resulting in an improvement in symptoms. Two meta-analyses and several large retrospective studies indicate that zinc is equally effective as chelators for the treatment of WD, with the advantages of a very low level of toxicity and only the minor side effect of gastric disturbance. Zinc is recommended as a first-line treatment for neurological presentations and is gaining acceptance for hepatic presentations. It is universally recommended for lifelong maintenance therapy and for presymptomatic WD.

Abstract
The insertion of a ureteral stent provides acute care by restoring urine flow and alleviating urinary retention or dysfunction. The problems of encrustation, bacterial colonization and biofilm formation become increasingly important when ureteral stents are left in place for a longer period of time. One way to reduce encrustation and bacterial adherence is to modify the stent surface with a diamond-like carbon coating, in combination with copper doping. The biocompatibilities of the Elastollan® base material and the a-C:H/Cu-mulitilayer coating were tested in synthetic urine. The copper content in bladder tissue was determined by atomic absorption spectroscopy and in blood and in urine by inductively coupled plasma mass spectrometry. Encrustations on the materials were analyzed by scanning electron microscopy, energy dispersive X-ray spectroscopy and Fourier transform infrared spectroscopy. A therapeutic window for copper ions of 0.5–1.0 mM was determined to kill bacteria without affecting human urothelial cells. In the rat animal model, it was found that copper release did not reach toxic concentrations in the affecting tissue of the urinary tract or in the blood. The encrustation behavior of the surfaces showed that the roughness of the amorphous carbon layer with the copper doping is probably the causal factor for the higher encrustation.

Abstract
Wilson disease (WD) is a genetic disorder of copper metabolism caused by variants in the ATP7B gene, which are inherited in an autosomal recessive pattern. Despite all the advances made on pathogenesis, cellular biology, and genetics, to date, WD remains a diagnostic and therapeutic challenge. With this series of cases, we aim to illustrate the main challenges that clinicians may encounter when dealing with patients with WD: the difficulties with clinical diagnosis, the therapeutic management of WD and the indication for advanced therapies, management during pregnancy, and genotype-phenotype correlations.

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 Bibliometric have been widely applied to the evaluation of academic productivity. However, those of individuals or institutions on a specific disease have not been explored. The aim of the present study is to conduct a bibliometric analysis of particular rare disease and investigate whether those doctors and hospitals with higher index screened by this method specialize in this disease. Methods A representative rare disease, Wilson disease (WD), was searched on Clarivate Analytics’ Web of Science and Elsevier’s Scopus, which was published in English between 1 January 2001 and 31 December 2020. Clinical authors and medical institutions with the most papers were screened, and their total number of publications and citations, h-index and g-index were computed and then ranked by h-index. Results A total of 6856 and 6193 papers and 200 and 160 authors were got from WoS and Scopus, respectively. Scopus provided 160 institutions. The above bibliometric indices were calculated in 100 researchers and 80 institutions, and top 30 authors (Top-30a) and top 20 institutions (Top-20i) of them based on the h-index were listed in the tables. Top-30a came from seven specialties and 13 countries whose median (interquartile range) h-index was 14 (12–19.5) (range 10–28) which was located between associate and full professors in some other disciplines. Top-20i was distributed in 13 countries whose mean ± standard deviation of the h-index was 15 ± 4.9 (range 10–27). Conclusions The related specialists and medical institutions of WD screened by specific disease bibliometric analysis are eminent and credible and benefit WD patients to obtain reliable medical treatment. This model may be suitable for other rare diseases. Supplementary Information The online version contains supplementary material available at 10.1186/s13023-022-02459-7.

Low Copper Diet—A Therapeutic Option for Wilson Disease? CHILDREN 2022; 9:children9081132. [PMID: 36010023 PMCID: PMC9406399 DOI: 10.3390/children9081132] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 07/11/2022] [Accepted: 07/27/2022] [Indexed: 11/17/2022]
Abstract
Wilson’s disease (WD) is an autosomal recessive inherited disease in which a pathological storage of copper in various organs is the mean pathophysiological mechanism. The therapy consists of drug therapy with chelating agents or zinc. For patients, nutrition is always an important issue. The aim of this review was to determine whether there are clear recommendations for a low copper diet for WD patients, or whether the essential trace element zinc plays a role? We were able to show that some of the foods with high copper content would have to be consumed in such large quantities that this is regularly not the case. Furthermore, there are also different absorption rates depending on the copper content. A lower copper intake only prevents the re-accumulation of copper. In summary, consistent adherence to drug therapy is more important than a strict diet. Only two foods should be consistently avoided: Liver and Shellfish.

Efficacy and Safety of Two Salts of Trientine in the Treatment of Wilson’s Disease. J Clin Med 2022; 11:jcm11143975. [PMID: 35887738 PMCID: PMC9325285 DOI: 10.3390/jcm11143975] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 06/30/2022] [Accepted: 07/06/2022] [Indexed: 11/24/2022] Open
Abstract
Background: Wilson’s disease (WD) is one of the few genetic disorders that can be successfully treated with pharmacological agents. Copper-chelating agents (D-penicillamine and Trientine salts) and zinc salts have been demonstrated to be effective. There are two salts of trientine. Trientine dihydrochloride salt (TETA 2HCL) is unstable at room temperature and requires storage at 2–8 °C. Trientine tetrahydrochloride (TETA 4HCL) is a more stable salt of trientine that can be stored at room temperature. No comparative study between both of the salts of trientine has been performed to date. As the two chemical forms were available in France between 1970 and 2009, we conducted a study to evaluate their efficacy and safety profiles. Methods: This retrospective cohort study was conducted by reviewing data from the national WD registry in France. Forty-three WD patients who received TETA 2HCL or TETA 4HCL monotherapy for at least one year until 2010 were included. The primary endpoints were hepatic and neurological outcomes. Secondary endpoints were the events leading to a discontinuation of medication. Results: Changes in medication were common, leading to the analysis of 57 treatment sequences of TETA 4HCL or TETA 2HCL. The mean duration of treatment sequence was significantly longer in the TETA 4 HCL group (12.6 years) than in the TETA 2HCL group (7.6 years) (p = 0.011). Ten patients experienced both trientine salts: eight stopped TETA 4 HCL (six had a hepatologic phenotype and two had a neurological phenotype) because this treatment was not available anymore (mean duration 7.4 years). Three of these patients already experienced TETA 2 HCL before the sequence. Two patients with a hepatologic phenotype (one had a previous sequence of TETA 4 HCL before) stopped TETA 2 HCL because of cold storage issues (mean duration 42.8 years). The total number of sequences was 57. All of the patients were clinically stable. No difference in efficacy was detected. Both treatments were well tolerated, except for a case of recurrence of lupus erythematosus-like syndrome in the TETA 2HCL group. The major reason for interruption of TETA 4HCL was due to a discontinuation in production of this salt. The reasons for stopping TETA 2HCL were mainly due to adherence issues largely attributed to the cold storage requirement. Conclusions: The two salts of trientine were effective in treating patients with WD. However, interruption of TETA 2HCL was frequent, linked to the cold storage requirement. As adherence to treatment is a key factor in the successful management of WD, physicians need to be even more vigilant in detecting adherence difficulties in patients receiving treatment with TETA 2HCL.

Different Response Behavior to Therapeutic Approaches in Homozygotic Wilson's Disease Twins with Clinical Phenotypic Variability: Case Report and Literature Review. Genes (Basel) 2022; 13:genes13071217.

Abstract
Background: Wilson’s disease (WD) is an autosomal-recessive disorder of copper deposition caused by pathogenic variants in the copper-transporting ATP7B gene. There is not a clear correlation between genotype and phenotype in WD regarding symptom manifestations. This is supported by the presentation of genetically identical WD twins with phenotypic discordance and different response behavior to WD-specific therapy. Case Presentation: One of the female homozygous twins (age: 26 yrs) developed writing, speaking, swallowing and walking deficits which led to in-patient examination without conclusive results but recommended genetic testing. Both sisters were tested and were heterozygous for the C.2304dupC;p(Met769Hisf*26) and the C.3207C>A;p(His1069Gln) mutation. Self-medication of the affected sibling with 450 mg D-penicillamine (DPA) did not prevent further deterioration. She developed a juvenile parkinsonian syndrome and became wheelchair-bound and anarthric. A percutaneous endoscopic gastrostomy was applied. Her asymptomatic sister helped her with her daily life. Despite the immediate increase of the DPA dose (up to 1800 mg within 3 weeks) in the severely affected patient and the initiation of DPA therapy (up to 600 mg within 2 weeks) in the asymptomatic patient after the first visit in our institution, liver function tests further deteriorated in both patients. After 2 months, the parkinsonian patient started to improve and walk again, but experienced several falls, broke her right shoulder and underwent two necessary surgical interventions. With further consequent copper elimination therapy, liver dysfunction improved in both patients, without need for orthotopic liver transplantation (LTX) in the severely affected patient. Her excellent recovery of liver and brain dysfunction was only transiently interrupted by the development of a nephrotic syndrome which disappeared after switching to Cuprior®. Unfortunately, she died from fulminant pneumonia. Conclusion: Despite identical genetic disposition, WD symptom presentations may develop differently in monozygotic twins, and they may need to be placed on a very different therapeutical regimen. The underlying gene-environment interaction is unclear so far.

Abstract
A woman in her 30s with unclear history of cirrhosis presented to the emergency department with 8 months of worsening bilateral hand tremors, falls, depressed mood, altered mental status, difficulty swallowing and faecal/urinary incontinence. The patient was diagnosed with liver cirrhosis 6 years prior based on outside hospital ultrasound and liver biopsy. The hospital inpatient neurology team was promptly consulted for evaluation of worsening mental status. Kayser-Fleischer rings were visible without slit-lamp examination on clinical exam, as were prominent hand tremors and ataxia on finger-nose-finger task. Brain MRI showed increased T2/FLAIR (fluid-attenuated inversion recovery) signal within the thalami, midbrain and pons demonstrating a 'double panda sign'. Laboratory findings confirmed a diagnosis of Wilson's disease. Penicillamine and subsequent zinc therapy were initiated. Patient was eventually discharged home with plans for outpatient physical therapy and hepatology management. Two months from presentation, the patient reported significant improvement in ataxia, motor function, swallow function and incontinence.

Abstract
INTRODUCTION Wilson's disease (WD) is a genetic disorder with pathological copper accumulation and associated clinical symptoms in various organs, particularly the liver and brain. Neurological disease is assessed with the clinical Unified Wilson's Disease Rating Scale (UWDRS). There is a lack of quantitative objective markers evaluating brain involvement. Recently, a semiquantitative brain magnetic resonance imaging (MRI) scale has been proposed, which combines acute toxicity and chronic damage measures into a total score. The relationship between MRI brain pathology and the MRI scale with disease form and neurological severity was studied in a large cohort. METHODS We retrospectively assessed 100 newly diagnosed treatment-naïve patients with WD with respect to brain MRI pathology and MRI scores (acute toxicity, chronic damage, and total) and analyzed the relationship with disease form and UWDRS part II (functional impairment) and part III (neurological deficits) scores. RESULTS Most patients had the neurological form of WD (55%) followed by hepatic (31%) and presymptomatic (14%). MRI examination revealed WD-typical abnormalities in 56% of patients, with higher pathology rates in neurological cases (83%) than in hepatic (29%) and presymptomatic (7%) cases. UWDRS part II and III scores correlated with the MRI acute toxicity score (r = 0.55 and 0.55, respectively), chronic damage score (r = 0.39 and 0.45), and total score (0.45 and 0.52) (all P < 0.01). CONCLUSIONS Brain MRI changes may be present even in patients without neurological symptoms, although not frequently. The semiquantitative MRI scale correlated with the UWDRS and appears to be a complementary tool for severity of brain injury assessment in WD patients.

Abstract
Wilson disease (WD) is caused by biallelic pathogenic variants in adenosine triphosphatase copper-transporting beta (ATP7B); however, genetic testing identifies only one or no pathogenic ATP7B variant in a number of patients with WD. Synonymous single-nucleotide sequence variants have been recognized as pathogenic in individual families. The aim of the present study was to evaluate the prevalence and disease mechanism of the synonymous variant c.2292C>T (p.Phe764=) in WD. A cohort of 280 patients with WD heterozygous for a single ATP7B variant was investigated for the presence of c.2292C>T (p.Phe764=). In this cohort of otherwise genetically unexplained WD, the allele frequency of c.2292C>T (p.Phe764=) was 2.5% (14 of 560) compared to 7.1 × 10-6 in the general population (2 of 280,964 in the Genome Aggregation Database; p < 10-5 ; Fisher exact test). In an independent United Kingdom (UK) cohort, 2 patients with WD homozygous for p.Phe764= were identified. RNA analysis of ATP7B transcripts from patients homozygous or heterozygous for c.2292C>T and control fibroblasts showed that this variant caused high expression of an ATP7B transcript variant lacking exon 8. Conclusion: The synonymous ATP7B variant c.2292C>T (p.Phe764=) causes abnormal messenger RNA processing of ATP7B transcripts and is associated with WD in compound heterozygotes and homozygotes.

Abstract
Aim Wilson's disease (WD) is a rare autosomal recessive disease, that can involve any organ of the body, the main ones being the liver and the brain. These patients can have varied presentations, ranging from having no symptoms to having neurological manifestations to features of chronic liver disease (CLD). Those patients that end up having CLD are prognosticated via the Child-Turcotte-Pugh (CTP) score and the Model for End-stage Liver Disease (MELD) score. However, two specific scores exist for prognostication in patients having WD, namely, the Nazar score and the Dhawan score. However, these are yet to be validated nor has their use been implemented in clinical practice. Materials and methods Our study involved 65 patients with WD, comprising both the pediatric and the adult population. We aimed at evaluating the clinical manifestations the lab parameters and the management of these patients. Furthermore, we tried validating the Nazar and the Dhawan score and later compared them with the CTP and the MELD score, which are well-known prognostic tools in CLD. Results Our patients were subdivided into the pediatric (more than 50%) and the adult group. The most common presenting complaint noted in both groups was abdominal distension. Values of the urine copper and serum ceruloplasmin did not defer between the pediatric and adult patients. Hepatic involvement is frequently seen in the pediatric age-group. Also, CTP class C was chiefly seen in pediatrics 17/33 (51.5%), while CTP class B was in adults 13/32 (40.6%). The mean Nazar score was 3 ± 3, while the mean Dhawan score was 5 ± 4. The main treatment offered for both groups was zinc along with penicillamine. Conclusion Our study showed the Dhawan score was comparable to the CTP and the MELD score in terms of predicting the disease severity of WD in our patient population.

Abstract
Background Histopathological studies in Wilson's disease (WD) have revealed increased copper and iron concentrations in the deep gray matter nuclei. However, the commonly used mean bulk susceptibility only reflects the regional metal concentration rather than the total metal content, and regional atrophy may affect the assessment of mean bulk susceptibility. Our study aimed to quantitatively assess the changes of metal concentration and total metal content in deep gray matter nuclei by quantitative susceptibility mapping to distinguish patients with neurological and hepatic WD from healthy controls. Methods Quantitative susceptibility maps were obtained from 20 patients with neurological WD, 10 patients with hepatic WD, and 25 healthy controls on a 3T magnetic resonance imaging system. Mean bulk susceptibility, volumes, and total susceptibility of deep gray matter nuclei in different groups were compared using a linear regression model. The area under the curve (AUC) was calculated by receiver characteristic curve to analyze the diagnostic capability of mean bulk susceptibility and total susceptibility. Results Mean bulk susceptibility and total susceptibility of multiple deep gray matter nuclei in patients with WD were higher than those in healthy controls. Compared with patients with hepatic WD, patients with neurological WD had higher mean bulk susceptibility but similar total susceptibility in the head of the caudate nuclei, globus pallidus, and putamen. Mean bulk susceptibility of putamen demonstrated the best diagnostic capability for patients with neurological WD, the AUC was 1, and the sensitivity and specificity were all equal to 1. Total susceptibility of pontine tegmentum was most significant for the diagnosis of patients with hepatic WD, the AUC was 0.848, and the sensitivity and specificity were 0.7 and 0.96, respectively. Conclusion Brain atrophy may affect the assessment of mean bulk susceptibility in the deep gray matter nuclei of patients with WD, and total susceptibility should be an additional metric for total metal content assessment. Mean bulk susceptibility and total susceptibility of deep gray matter nuclei may be helpful for the early diagnosis of WD.

Abstract
Objective We reported the case of a patient with Wilson's disease (WD) with acute-onset visual impairment and summarized previously reported cases to make physicians aware of the complicated clinical expressions of WD and improve diagnosis efficiency. Methods The patient was recruited from the Second Affiliated Hospital of Zhejiang University School of Medicine. Clinical data, including cranial images, laboratory tests, and ophthalmic findings were obtained. The PubMed database was searched for published cases of WD with visual impairment. Results We reported a 22-year-old male who presented with hand tremor, personality change, and acute-onset binocular vision blurring. WD was considered to be closely correlated with neuropsychiatric and ocular involvements. After low-copper diet and regular copper-chelation therapy, the related symptoms improved compared to before. Six WD cases of optic neuropathy have been reported, including ours. The patients usually had neurological and/or hepatic symptoms for a period without any treatment. All the reported cases manifested as acute episodes of visual changes, and the ocular manifestations improved after copper-chelation treatment. Conclusions Excess copper accumulation may be a rare cause of visual impairment in patients with WD. While the etiology behind patients' acute-onset visual impairment remained uncertain, the possibility of WD should be considered through neuropsychiatric and hepatic symptoms, corneal K-F rings, decreased serum ceruloplasmin, and low likelihood or exclusion of other causes. Clinicians need to recognize this rare manifestation and give appropriate treatment to avoid misdiagnosis and unnecessary overtreatment.

Abstract
Diagnosis of AIH is based on a combination of clinical, laboratory and histological information. It has been formalised by diagnostic scoring systems, to which liver biopsy contributes substantially. Diagnostic biopsy is thus, desirable in nearly all patients. An adequate biopsy size, provision by clinicians of adequate information to histopathologists and active discussion at regular meetings are all important for accurate histological diagnosis. Recently, the specificity of some features previously thought to suggest AIH has been questioned, and new recommendations for histological diagnosis have been proposed, although not yet validated. The histology of acutely presenting AIH and that of severe or fulminant AIH include some characteristic features. Primary biliary cholangitis, primary sclerosing cholangitis and non-alcoholic fatty liver disease may co-exist with AIH on biopsy. Liver biopsy also enables grading of severity of inflammation and staging of fibrosis. Presence of cirrhosis is a poor prognostic marker. Repeat liver biopsy after achieving biochemical remission, although not performed routinely, enables assessment of (a) histological remission, a favourable prognostic indicator and (b) fibrosis progression. It can thus help determine further management.

Abstract
Introduction Most neurodegenerative and chronic liver disorders are associated with sleep disturbances (SD). SD may be expected to occur in patients with Wilson’s disease (WD), an inherited disorder of copper metabolism that mostly affects the liver and brain; however, there is a lack of observations, particularly in treatment-naïve WD patients. Methods We evaluated SD in 19 newly diagnosed treatment-naïve WD patients. All patients completed the Beck Depression Inventory (BDI), the Athens Insomnia Scale (AIS) and the Epworth Sleepiness Scale (ESS), and underwent nightlong video polysomnography (vPSG). Results of vPSG in WD patients were compared with results from 19 sex- and age-matched healthy controls. Results Depressive symptoms were not reported by patients on routine examination although three patients were diagnosed with mild depression. No patients reported SD during routine examination; three patients had insomnia according to the AIS and all patients scored 0 on the ESS. Despite the lack of reporting of SD by patients, significant differences were observed between WD patients and controls following vPSG analysis: WD patients had shorter mean total sleeping time (366.2 vs. 451.7 min), a lower percentage of rapid-eye movement (15.4 vs. 20.6%), longer sleep latency (36.7 vs. 10.4 min) and lower sleep efficiency (76.2 vs. 93.8%) (all P ≤ 0.01). SD tended to be worse in patients with neurological WD compared with hepatic WD. Conclusions As SD may precede depression and severely affect quality of life, our findings suggest that patients with WD should be screened for SD with suitable methods.

Abstract
Background Wilson disease (WD) is caused by mutations in the copper-transporting P-type adenosine triphosphatase encoded by the ATP7B gene. In this study, we screened and identified the ATP7B mutations among unrelated Vietnamese pediatric patients. Methods One-hundred-thirteen pediatric patients with clinically diagnosed WD were recruited. DNA samples were extracted from peripheral blood. Mutations in the ATP7B gene were identified by Sanger sequencing. Results Approximately 98% of the clinically diagnosed WD patients carried ATP7B mutations. A total of 35 different ATP7B variants were detected, including five novel mutations (L658P, L792P, T977K, IVS4 + 1G > A and IVS20 + 4A > G). Remarkably, this study revealed that S105* was the most prevalent variant (32.27%), followed by L1371P (9.09%), I1148T (7.27%), R778L (6.36%), T850I (5.45%), V176Sfs*28 and IVS14-2A > G (4.55%). Most ATP7B mutations were located in the exon 2 (37.73%), exon 16 (10.00%), exon 8 (9.55%), exon 20 (9.09%), exon 10 and exon 18 (5.45%), exon 14 (5.00%), exon 13 and intron 14 (4.55%). We developed a streamlined procedure to quickly characterize mutations in the ATP7B gene in the Vietnamese children, starting with sequencing exon 2 and subsequently to exons 8,10,13-16,18, and 20 to allow quick diagnosis of clinically suspected patients. Conclusion The mutational spectrum and hotspots of ATP7B gene in the Vietnamese population were fairly different from other East Asian populations. A streamlined procedure was developed to screen exon 2 in ATP7B gene among suspected WD patients to reduce genetically diagnostic cost, to facilitate early detection and intervention in countries with limited resources.

Abstract
BACKGROUND AND AIMS Wilson's disease (WD) is a genetic disease with systemic accumulation of copper that leads to symptoms from the liver and brain. However, the underlying defects in copper transport kinetics are only partly understood. We sought to quantify hepatic copper turnover in patients with WD compared with heterozygote and control subjects using PET with copper-64 (64 Cu) as a tracer. Furthermore, we assessed the diagnostic potential of the method. APPROACH AND RESULTS Nine patients with WD, 5 healthy heterozygote subjects, and 8 healthy controls were injected with an i.v. bolus of 64 Cu followed by a 90-min dynamic PET scan of the liver and static whole-body PET/CT scans after 1.5, 6, and 20 h. Blood 64 Cu concentrations were measured in parallel. Hepatic copper retention and redistribution were evaluated by standardized uptake values (SUVs). At 90 min, hepatic SUVs were similar in the three groups. In contrast, at 20 h postinjection, the SUV in WD patients (mean ± SEM, 31 ± 4) was higher than in heterozygotes (24 ± 3) and controls (21 ± 4; p < 0.001). An SUV-ratio of hepatic 64 Cu concentration at 20 and 1.5 h completely discriminated between WD patients and control groups (p < 0.0001; ANOVA). By Patlak analysis of the initial 90 min of the PET scan, the steady-state hepatic clearance of 64 Cu was estimated to be slightly lower in patients with WD than in controls (p = 0.04). CONCLUSIONS 64 Cu PET imaging enables visualization and quantification of the hepatic copper retention characteristic for WD patients. This method represents a valuable tool for future studies of WD pathophysiology, and may assist the development of therapies, and accurate diagnosis.

Abstract
Wilson's disease is an autosomal-recessive disorder of copper metabolism with hepatic, neurological, psychiatric, ophthalmological, haematological, renal, and rheumatological manifestations. Making a diagnosis can be challenging given that no single test can confirm or exclude the disease, and diagnostic delays are common. Treatment protocols vary and adverse effects, including paradoxical neurological worsening, can occur. In this Review, we provide a practical guide to the diagnosis of Wilson's disease. We include recommendations on indications for testing, how to interpret results, and when additional investigations are required. We also cover treatment initiation, ideally under the guidance of a specialist centre for Wilson's disease, and the principles behind long-term management. This guidance was developed by a multidisciplinary group of Wilson's disease experts formed through the British Association for the Study of the Liver. The guidance has been endorsed by the British Society of Gastroenterology and approved by the Association of British Neurologists.

Abstract
Wilson's disease (WD) is an inherited disorder of copper metabolism caused by mutations in the ATP7B gene. This condition is characterized by the accumulation of copper in the liver and other organs and tissues causing hepatic and neuropsychiatric manifestations. This paper reviews the diagnostic performance and limitations of the biochemical tests commonly used to detect this underdiagnosed disease. It also provides some recommendations and suggests a set of standardized laboratory comments. At present, a rapid, simple, reliable biochemical test that confirms diagnosis of WD is not available. However, diagnosis can be established based on serum ceruloplasmin and urinary copper excretion. Total serum copper should be employed with caution, since it has a low negative predictive value. The use of estimated non-ceruloplasmin-bound copper is not recommended. Nevertheless, measured relative exchangeable copper has very high sensitivity and specificity and emerges as a potential gold standard for the biochemical diagnosis of WD. The development of novel assays for WD detection makes this disorder a potential candidate to be included in newborn screening programs.
