Gender-related alterations of serum trace elements and neurometabolism in the anterior cingulate cortex of patients with major depressive disorder. J Affect Disord 2024; 360:176-187. [PMID: 38723680 DOI: 10.1016/j.jad.2024.05.039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2023] [Revised: 04/08/2024] [Accepted: 05/06/2024] [Indexed: 06/04/2024]
Abstract
BACKGROUND It is widely known that sex differences have a significant impact on patients with major depressive disorder (MDD). This study aims to evaluate the sex-related connection between serum trace elements and changes in neurometabolism in the anterior cingulate cortex (ACC) of MDD patients. METHODS 109 untreated MDD patients and 59 healthy controls underwent proton magnetic resonance spectroscopy (1H-MRS) under resting conditions. We measured metabolic ratios in the ACC from both sides. Additionally, venous blood samples were taken from all participants to detect calcium (Ca), phosphorus, magnesium (Mg), copper (Cu), ceruloplasmin (CER), zinc (Zn), and iron (Fe) levels. We performed association and interaction analyses to explore the connections between the disease and gender. RESULTS In individuals with MDD, the Cu/Zn ratio increased, while the levels of Mg, CER, Zn and Fe decreased. Male MDD patients had lower Cu levels, while female patients had an increased Cu/Zn ratio. We observed significant gender differences in Cu, CER and the Cu/Zn ratio in MDD. Male patients showed a reduced N-acetyl aspartate (NAA)/phosphocreatine + creatine (PCr + Cr) ratio in the left ACC. The NAA/PCr + Cr ratio decreased in the right ACC in patients with MDD. In the left ACC of male MDD patients, the Cu/Zn ratio was inversely related to the NAA/PCr + Cr ratio, and Fe levels were negatively associated with the GPC + PC/PCr + Cr ratio. CONCLUSIONS Our findings highlight gender-specific changes in Cu homeostasis among male MDD patients. The Cu/Zn ratio and Fe levels in male MDD patients were significantly linked to neurometabolic alterations in the ACC.

Abstract
BACKGROUND AND AIMS Many children with Wilson's disease are complicated with dyslipidemia. The aim of this study was to investigate the risk factors for the development of fatty liver disease (FLD) in children with Wilson's disease. METHODS We evaluated sex, age, weight, the disease course, treatment course, clinical classification, alanine transaminase (ALT), aspartate transaminase, γ-glutamyl transpeptidase, total biliary acid, triglyceride, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, homocysteine, uric acid, fibrinogen (FBG), creatinine, procollagen III N-terminal propeptide, laminin, hyaluronic acid, type IV collagen, and performed receiver operating characteristic curve analysis to investigate the forecast value of individual biochemical predictors and combined predictive indicators to evaluate FLD in Wilson's disease. RESULTS The multivariate logistic regression analysis revealed that ALT [odds ratio (OR), 1.011; 95% confidence interval (CI), 1.004-1.02; P = 0.006], uric acid (OR, 1.01; 95% CI, 1.002-1.018; P = 0.017), FBG (OR, 3.668; 95% CI, 1.145-13.71; P = 0.037), creatinine (OR, 0.872; 95% CI, 0.81-0.925; P < 0.001), and laminin (OR, 1.01; 95% CI, 1.002-1.018; P = 0.017) acted as independent risk factors in Wilson's disease complicated with FLD. The receiver operating characteristic curves for combined predictive indicators demonstrated an area under the curve values of 0.872, which was found to be a significant predictors for FLD in Wilson's disease. CONCLUSIONS We screened out the most important risk factors, namely ALT, uric acid, creatinine, FBG, and laminin for Wilson's disease complicated with FLD. The joint prediction achieved is crucial for identifying children with Wilson's disease complicated with FLD.

Abstract
BACKGROUND AND AIMS Distinctive gut microbial profiles have been observed between patients with Wilson disease (WD) and healthy individuals. Despite this, the exact relationship and influence of gut microbiota on the advancement of WD-related liver damage remain ambiguous. This research seeks to clarify the gut microbiota characteristics in both human patients and mouse models of WD, as well as their impact on liver injury. METHODS Gut microbial features in healthy individuals, patients with WD, healthy mice and mice with early- and late-stage WD were analysed using 16S rRNA gene sequencing. Additionally, WD-afflicted mice underwent treatment with either an antibiotic cocktail (with normal saline as a control) or healthy microbiota (using disease microbiota as a control). The study assessed gut microbiota composition, hepatic transcriptome profiles, liver copper concentrations and hepatic pathological injuries. RESULTS Patients with hepatic WD and mice with WD-related liver injury displayed altered gut microbiota composition, notably with a significant reduction in Lactobacillus abundance. Additionally, the abundances of several gut genera, including Lactobacillus, Veillonella and Eubacterium coprostanoligenes, showed significant correlations with the severity of liver injury in patients with WD. In WD mice, antibiotic treatment or transplantation of healthy microbiota altered the gut microbial structure, increased Lactobacillus abundance and modified the hepatic transcriptional profile. These interventions resulted in reduced hepatic copper concentration and alleviation of WD-related liver injury. CONCLUSIONS Individuals and mice with pronounced WD-related liver injury exhibited shifts in gut microbial composition. Regulating gut microbiota through healthy microbiota transplantation emerges as a promising therapeutic approach for treating WD-related liver injury.

Abstract
BACKGROUND AND AIM In this study, we used a national cohort of patients with Wilson's disease (WD) to investigate the admissions, mortality rates, and costs over the captured period to assess specific subpopulations at higher burden. METHODS Patients with WD were selected using 2016-2019 National Inpatient Sample (NIS). The weighted estimates and patient data were stratified using demographics and medical characteristics. Regression curves were graphed to derive goodness-of-fit for each trend from which R2 and P values were calculated. RESULTS Annual total admissions per 100 000 hospitalizations due to WD were 1075, 1180, 1140, and 1330 ( R2 = 0.75; P = 0.13) from 2016 to 2019. Within the demographics, there was an increase in admissions among patients greater than 65 years of age ( R2 = 0.90; P = 0.05) and White patients ( R2 = 0.97; P = 0.02). Assessing WD-related mortality rates, there was an increase in the mortality rate among those in the first quartile of income ( R2 = 1.00; P < 0.001). The total cost for WD-related hospitalizations was $20.90, $27.23, $24.20, and $27.25 million US dollars for the years 2016, 2017, 2018, and 2019, respectively ( R2 = 0.47; P = 0.32). There was an increasing total cost trend for Asian or Pacific Islander patients ( R2 = 0.90; P = 0.05). Interestingly, patients with cirrhosis demonstrated a decreased trend in the total costs ( R2 = 0.97; P = 0.02). CONCLUSION Our study demonstrated that certain ethnicity groups, income classes and comorbidities had increased admissions or costs among patients admitted with WD.

Abstract
BACKGROUND AND AIMS Wilson's disease may progress to cirrhosis and clinically significant portal hypertension (CSPH). We aimed to assess the prevalence and prognostic impact of CSPH-related features on hepatic decompensation and transplant-free survival in patients with Wilson's disease. METHODS AND RESULTS About 137 patients with Wilson's disease (Leipzig score ≥4), followed for a median observation period of 9.0 (3.9-17.7) years at the Vienna General Hospital, were included in this retrospective study. Overall, 49 (35.8%) developed features of CSPH: 14 (10.2%) varices, 40 (29.2%) splenomegaly, 20 (14.6%) ascites, 18 (13.1%) hepatic encephalopathy and 3 (2.2%) experienced acute variceal bleeding. Overall, 8 (5.8%) patients died, including three deaths caused by CSPH-related complications. Within 10 years, compensated patients with features of CSPH developed more decompensation events (8.3% vs. 1.5% in patients without CSPH, p = 0.3) and had worse transplant-free-survival (91.7% vs. 98.6%), which further declined in patients with hepatic decompensation (26.7%, log-rank: p < 0.0001). Patients with liver stiffness <15 kPa and normal platelets (≥150 G/L) were less likely to decompensate within 10 years (2.6% vs. 8.4%, p = 0.002) and had a better 10-year transplant-free-survival (97.7% vs. 83.9%, p = 0.006). CONCLUSIONS Patients with Wilson's disease developing features of CSPH are at an increased risk for hepatic decompensation and liver-related mortality, warranting for regular screening and timely initiation of effective CSPH-directed treatments.

Abstract
Humans are continuously exposed to various heavy metals including copper, iron, cadmium, and arsenic, which were specifically selected for the current analysis because they are among the most frequently encountered environmental mankind and industrial pollutants potentially causing human health hazards and liver injury. So far, these issues were poorly assessed and remained a matter of debate, also due to inconsistent results. The aim of the actual report is to thoroughly analyze the positive as well as negative effects of these four heavy metals on human health. Copper and iron are correctly viewed as pollutant elements essential for maintaining human health because they are part of important enzymes and metabolic pathways. Healthy individuals are prepared through various genetically based mechanisms to maintain cellular copper and iron homeostasis, thereby circumventing or reducing hazardous liver and organ injury due to excessive amounts of these metals continuously entering the human body. In a few humans with gene aberration, however, liver and organ injury may develop because excessively accumulated copper can lead to Wilson disease and substantial iron deposition to hemochromatosis. At the molecular level, toxicities of some heavy metals are traced back to the Haber Weiss and Fenton reactions involving reactive oxygen species formed in the course of oxidative stress. On the other hand, cellular homeostasis for cadmium and arsenic cannot be provided, causing their life-long excessive deposition in the liver and other organs. Consequently, cadmium and arsenic represent health hazards leading to higher disability-adjusted life years and increased mortality rates due to cancer and non-cancer diseases. For unknown reasons, however, liver injury in humans exposed to cadmium and arsenic is rarely observed. In sum, copper and iron are good for the human health of most individuals except for those with Wilson disease or hemochromatosis at risk of liver injury through radical formation, while cadmium and arsenic lack any beneficial effects but rather are potentially hazardous to human health with a focus on increased disability potential and risk for cancer. Primary efforts should focus on reducing the industrial emission of hazardous heavy metals.

Abstract
BACKGROUND Wilson disease (WD) is an autosomal recessive disorder that leads to organ toxicity due to copper overload. Early diagnosis is complicated by the rarity and diversity of manifestations. OBJECTIVE To describe the diagnostic features and response to treatment in our cohort of WD patients. METHODS This was a retrospective analysis of 262 WD patients stratified by clinical presentation, complementary exams, ATP7B genotyping, and response to treatment. RESULTS Symptoms occurred at an average age of 17.4 (7-49) years, and patients were followed up for an average of 9.6 (0-45) years. Patients presented mainly with hepatic (36.3%), neurologic (34.7%), and neuropsychiatric (8.3%) forms. Other presentations were hematologic, renal, or musculoskeletal, and 16.8% of the patients were asymptomatic. Kayser-Fleischer rings occurred in 78.3% of the patients, hypoceruloplasminemia in 98.3%, and elevated cupruria/24h in 73.0%, with an increase after D-penicillamine in 54.0%. Mutations of the ATP7B gene were detected in 84.4% of alleles. Brain magnetic resonance imaging showed abnormalities in the basal ganglia in 77.7% of patients. D-penicillamine was the first choice in 93.6% of the 245 patients, and 21.1% of these patients were switched due to adverse effects. The second-line therapies were zinc and trientine. The therapeutic response did not differ significantly between the drugs (p = 0.2). Nine patients underwent liver transplantation and 82 died. CONCLUSION Wilson disease is diagnosed at a late stage, and therapeutic options are limited. In people under 40 years of age with compatible manifestations, WD could be considered earlier in the differential diagnosis. There is a need to include ATP7B genotyping and therapeutic alternatives in clinical practice.

Abstract
Wilson's disease (WD) is an autosomal recessive disorder characterized by toxic accumulation of copper in the liver, brain, and other organs. The disease is caused by pathogenic variants in the ATP7B gene, which encodes a P-type copper transport ATPase. Diagnosing WD is associated with numerous difficulties due to the wide range of clinical manifestations and its unknown dependence on the physiological characteristics of the patient. This leads to a delay in the start of therapy and the subsequent deterioration of the patient's condition. However, in recent years, molecular genetic testing of patients using next generation sequencing (NGS) has been gaining popularity. This immediately affected the detection speed of WD. If, previously, the frequency of this disease was estimated at 1:35,000-45,000 people, now, when conducting large molecular genetic studies, the frequency is calculated as 1:7026 people. This certainly points to the problem of identifying WD patients. This review provides an update on the performance of epidemiological studies of WD and describes normal physiological functions of the protein and diversified disfunctions depending on pathogenic variants of the ATP7B gene. Future prospects in the development of WD genetic diagnostics are also discussed.

Abstract
A 73-year-old woman was referred to our hospital for persistent liver dysfunction. When the patient was 45 years old, her youngest sister had been diagnosed with Wilson disease (WD). The patient therefore underwent several family screening tests, all of which were unremarkable. She had an annual medical checkup and was diagnosed with liver dysfunction and fatty liver at 68 years old. A liver biopsy and genetic testing were performed, and she was diagnosed with WD; chelation therapy was then initiated. In patients with hepatic disorders and a family history of WD, multiple medical examinations should be conducted, as the development of WD is possible regardless of age.

[PMID: 37634880 DOI: 10.1016/j.gene.2023.147728] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 07/30/2023] [Accepted: 08/21/2023] [Indexed: 08/29/2023]
Abstract
BACKGROUND Wilson disease is caused by pathogenic variants in the ATP7B gene which encodes a copper-transporting ATPase. AIMS Describe a common founder pathogenic variant among Bukharan Jews and to assess its prevalence, clinical features, and outcome. METHODS The cohort consisted of patients of Bukharan Jewish descent diagnosed with Wilson disease at a tertiary pediatric medical center in 2013-2018. Clinical and genetic data were collected and analyzed. RESULTS Six patients from 4 unrelated families who were homozygous for the c.3784G > T p.(Val1262Phe) pathogenic variant in ATP7B were identified. Five presented with elevated aminotransferase levels, and one, with acute liver failure. Mean age at diagnosis was 8.7 years (5-12.5). Serum ceruloplasmin level was extremely low in all patients (1.9-7 mg/dL; mean 3.2(. The variant was identified in a heterozygous state in 5/153 Bukharan Jews; 2/33 from our local exome database and 3/120 healthy unrelated Bukharan Jews in another cohort, for an estimated carrier frequency of ∼1:30. CONCLUSIONS We report a common founder pathogenic variant in the ATP7B gene among Bukharan Jews associated with severe early-onset Wilson disease. Given the clinical severity, high frequency of the variant, and being a treatable disease, its inclusion in pre-symptomatic screening in the Bukharan Jewish community should be considered. Furthermore, WD should be part of future genetic newborn screening programs in Israel and worldwide, to enable early treatment and prevention of future life-threatening complications.

Abstract
Background: Wilson's disease (WD) is a copper metabolism disorder caused by ATP7B gene mutations and shows an autosomal recessive pattern of inheritance. We aimed to contribute to the mutation profile of ATP7B and show demographic and phenotypic differences in this study. Materials and methods: The clinical and demographic characteristics of patients who underwent ATP7B gene sequence analysis using next-generation sequencing were evaluated to improve genotype-phenotype correlation in WD. Results: An uncertain significance (D563N) and seven likely pathogenic (Y532D, Y715Y, T977K, K1028*, E1086K, A1227Pfs*103, and E1242K) variants were identified as associated with WD. Uniparental disomy was detected in one case. Conclusion: Our work expanded the ATP7B variant spectrum and pointed to clinical heterogeneity in ATP7B variants among patients with WD. All symptomatic patients had hepatic involvement and were clinically and/or genetically diagnosed with WD in the pediatric period. T977K, A1003V, H1069Q, E1086K, and N1270S variants were associated with hepatic failure.

Abstract
Drug-induced liver injury (DILI) is an unwarranted problem and has been a scourge in the treatment of tuberculosis (TB) infection in general and children in particular. Usually, when the Antituberculosis treatment (ATT) regime is temporarily interrupted and modified, DILI subsides, and the whole treatment can be completed under supervision. We report a case of ATT-induced DILI not improving despite modification in the ATT regime, which ultimately led to the revealing of a yet unreported constellation of syndromes that included Wilson Disease, 46 XX gonadal dysgenesis, and Mayer Rokitansky Kuster Hauser (MRKH) Syndrome.

Abstract
Wilson disease is an autosomal recessive disorder affecting the ATP7B gene located on chromosome 13q. This leads to copper deposition in various organs, most importantly in the liver and brain. The genetic mutations are vast, well reported in the West but poorly documented in developing countries. Hence the diagnosis is made with a constellation of clinico-laboratory parameters which have significant overlap with other liver diseases and often pose a significant dilemma for clinicians. Diagnostic scoring systems are not fool-proof. The availability and affordability of chelators in developing countries impact the drug compliance of patients. While D-penicillamine is a potent drug, its side effects lead to drug discontinuation. Trientine is cost-prohibitive in developing countries. There is no single test to assess the adequacy of chelation. Exchangeable urinary copper is an essential upcoming diagnostic and prognostic tool. In the presence of cirrhosis, hypersplenism clouds the assessment of myelosuppression of drugs. Similarly, it may be difficult to distinguish disease tubulopathy from drug-induced glomerulonephritis. Neurological worsening due to chelators may appear similar to disease progression. Presentation as fulminant hepatic failure requires rapid workup. There is a limited window of opportunity to salvage these patients with the help of plasmapheresis and other liver-assisted devices. This review addresses the challenges and clinical dilemmas faced at beside in developing countries.

Abstract
There is uncertainty regarding Wilson's disease (WD) management. OBJECTIVES To assess, in a multicenter Spanish retrospective cohort study, whether the approach to WD is homogeneous among centers. METHODS Data on WD patients followed at 32 Spanish hospitals were collected. RESULTS 153 cases, 58% men, 20.6 years at diagnosis, 69.1% hepatic presentation, were followed for 15.5 years. Discordant results in non-invasive laboratory parameters were present in 39.8%. Intrahepatic copper concentration was pathologic in 82.4%. Genetic testing was only done in 56.6% with positive results in 83.9%. A definite WD diagnosis (Leipzig score ≥4) was retrospectively confirmed in 92.5% of cases. Chelating agents were standard initial therapy (75.2%) with frequent modifications (57%), particularly to maintenance zinc. Enzyme normalization was not achieved by one third, most commonly in the setting of poor compliance, lack of genetic mutations and/or presence of cardiometabolic risk factors. Although not statistically significant, there were trends for sex differences in number of diagnosed cases, age at diagnosis and biochemical response. CONCLUSIONS Significant heterogeneity in diagnosis and management of WD patients emerges from this multicenter study that includes both small and large reference centers. The incorporation of genetic testing will likely improve diagnosis. Sex differences need to be further explored.

Abstract
BACKGROUND Wilson disease (WD) is the most common genetic metabolic liver disease. Some studies have shown that comorbidities may have important effects on WD. Data on hepatitis B virus (HBV) infection in patients with WD are limited. AIM To investigate the prevalence and clinical impact of HBV infection in patients with WD. METHODS The clinical data of patients with WD were analyzed retrospectively, and the data of patients with concurrent WD and HBV infection were compared with those of patients with isolated WD. RESULTS Among a total of 915 WD patients recruited, the total prevalence of current and previous HBV infection was 2.1% [95% confidence interval (CI): 1.2%-3.0%] and 9.2% (95%CI: 7.3%-11.1%), respectively. The main finding of this study was the identification of 19 patients with concurrent WD and chronic hepatitis B (CHB) infection. The diagnosis of WD was missed in all but two patients with CHB infection. The mean delay in the diagnosis of WD in patients with concurrent WD and CHB infection was 32.5 mo, which was significantly longer than that in patients with isolated WD (10.5 mo). The rates of severe liver disease and mortality in patients with concurrent WD and CHB infection were significantly higher than those in patients with isolated WD (63.1% vs 19.3%, P = 0.000 and 36.8% vs 4.1%, P < 0.001, respectively). Binary logistic regression analysis revealed a significantly higher risk of severe liver disease at the diagnosis of WD in patients with current HBV infection [odds ratio (OR) = 7.748; 95%CI: 2.890-20.774; P = 0.000)] or previous HBV infection (OR = 5.525; 95%CI: 3.159-8.739; P = 0.000) than in patients with isolated WD. CONCLUSION The total prevalence of current HBV infection in patients with WD was 2.1%. The diagnosis of WD in CHB patients is usually missed. HBV infection is an independent risk factor for severe liver disease in WD patients. The diagnosis of WD should be ruled out in some patients with CHB infection.

Differences in the Time Course of Recovery from Brain and Liver Dysfunction in Conventional Long-Term Treatment of Wilson Disease. J Clin Med 2023; 12:4861. [PMID: 37510976 PMCID: PMC10381896 DOI: 10.3390/jcm12144861] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Revised: 06/30/2023] [Accepted: 07/21/2023] [Indexed: 07/30/2023] Open
Abstract
BACKGROUND The aim of this study was to demonstrate that both neurological and hepatic symptoms respond to copper chelation therapy in Wilson disease (WD). However, the time course of their recovery is different. METHODS Eighteen patients with neurological WD from a single specialized center who had been listed for liver transplantation during the last ten years and two newly diagnosed homozygous twins were recruited for this retrospective study. The mean duration of conventional treatment was 7.3 years (range: 0.25 to 36.2 years). A custom Wilson disease score with seven motor items, three non-motor items, and 33 biochemical parameters of the blood and urine, as well as the MELD score, was determined at various checkup visits during treatment. These data were extracted from the charts of the patients. RESULTS Treatment was initiated with severity-dependent doses (≥900 mg) of D-penicillamine (DPA) or triethylene-tetramin-dihydrochloride (TRIEN). The motor score improved in 10 and remained constant in 8 patients. Worsening of neurological symptoms was observed only in two patients who developed comorbidities (myasthenia gravis or hemispheric stroke). The neurological symptoms continuously improved over the years until the majority of patients became only mildly affected. In contrast to this slow recovery of the neurological symptoms, the MELD score and liver enzymes had already started to improve after 1 month and rapidly improved over the next 6 months in 19 patients. The cholinesterase levels continued to increase significantly (p < 0.0074) even further. One patient whose MELD score indicated further progression of liver disease received an orthotopic liver transplantation 3 months after the diagnosis of WD and the onset of DPA treatment. CONCLUSIONS Neurological and hepatic symptoms both respond to copper chelation therapy. For patients with acute liver failure, the first 4 months are critical. This is the time span in which patients have to wait either for a donor organ or until significant improvement has occurred under conventional therapy. For patients with severe neurological symptoms, it is important that they are treated with fairly high doses over several years.

Abstract
Background Wilson's disease (WD) is a recessive genetic disorder characterized by copper metabolism dysfunction. It is difficult to obtain an accurate diagnosis due to its variable clinical presentation. This study aimed to describe the clinical characteristics and diagnostic particularities in a series of Chinese WD patients. Methods The medical records of 371 patients with WD retrieved from January 2005 to December 2020 were retrospectively reviewed. Results The incidence of WD has a male predominance in the adult population. However, the difference in sex distribution is not significant in the pediatric population. Females have an earlier symptom onset than males. The most common initial symptoms were neuropsychiatric manifestations both in the pediatric population (49.7%) and adult population (69.8%), and there was a male predominance (61.8%). Eighty-two percent of patients presented with more than two neurologic symptoms. Fifty-two (14%) patients presented with psychiatric symptoms. The most common WD phenotype was the neuropsychiatric form (48%). The age of onset occurred earlier in patients with the hepatic phenotype than in those with the neuropsychiatric phenotype. Moreover, there was a significant difference in sex distribution regarding phenotype. Females presented with a hepatic phenotype more often than males, and the neuropsychiatric phenotype occurred more frequently in males with an older onset age. Further study showed that the age at onset was a deciding factor for predicting the neuropsychiatric phenotype among the hepatic phenotype. However, sex did not correlate with the phenotype. Conclusion Males seem to have a higher disease susceptibility, with symptom onset later than females. Males frequently present with a neuropsychiatric phenotype, while females present with a hepatic phenotype. Age at onset was a deciding factor for predicting the WD phenotype. Further studies focusing on the effect of estrogens on the pathology of WD are suggested.

Abstract
BACKGROUND & AIMS Wilson's disease is an inherited hepatoneurologic disorder caused by mutations in the copper transporter ATP7B. Liver disease from Wilson's disease is one leading cause of cirrhosis in adolescents. Current copper chelators and zinc salt treatments improve hepatic presentations but frequently worsen neurologic symptoms. In this study, we showed the function and machinery of neutrophil heterogeneity using a zebrafish/murine/cellular model of Wilson's disease. METHODS We investigated the neutrophil response in atp7b-/- zebrafish by live imaging, movement tracking, and transcriptional analysis in sorted cells. Experiments were conducted to validate liver neutrophil heterogeneity in Atp7b-/- mice. In vitro experiments were performed in ATP7B-knockout human hepatocellular carcinomas G2 cells and isolated bone marrow neutrophils to reveal the mechanism of neutrophil heterogeneity. RESULTS Recruitment of neutrophils into the liver is observed in atp7b-/- zebrafish. Pharmacologic stimulation of neutrophils aggravates liver and behavior defects in atp7b-/- zebrafish. Transcriptional analysis in sorted liver neutrophils from atp7b-/- zebrafish reveals a distinct transcriptional profile characteristic of N2 neutrophils. Furthermore, liver N2 neutrophils also were observed in ATP7B-knockout mice, and pharmacologically targeted transforming growth factor β1, DNA methyltransferase, or signal transducer and activator of transcription 3 reduces liver N2 neutrophils and improves liver function and alleviates liver inflammation and fibrosis in ATP7B-knockout mice. Epigenetic silencing of Socs3 expression by transforming growth factor β1 contributes to N2-neutrophil polarization in isolated bone marrow neutrophils. CONCLUSIONS Our findings provide a novel prospect that pharmacologic modulation of N2-neutrophil activity should be explored as an alternative therapeutic to improve liver function in Wilson's disease.

Abstract
Wilson's disease and HFE-hemochromatosis are autosomal-recessively inherited metabolic diseases of the liver. Copper overload in case of Wilson's disease and iron overload in case of hemochromatosis lead to organ damage of the liver and other organs. In order to diagnose these diseases at an early stage and introduce therapy, knowledge of the symptoms and diagnostic criteria of these diseases is important. Iron overload in hemochromatosis patients is treated with phlebotomies and copper overload in Wilson's disease patients with either chelating medications (D-penicillamine or trientine) or zinc salts. After introduction of lifelong therapy both diseases typically have a favorable disease course and further development of organ-damage can be prevented, especially with respect to liver-damage.

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
BACKGROUND Morphological changes of retina in patients with Wilson's disease (WD) can be found by optical coherence tomography (OCT), and such changes had significant differences between neurological forms (NWD) and hepatic forms (HWD) of WD. The aim of this study was to evaluate the relationship between morphological parameters of retina and brain magnetic resonance imaging (MRI) lesions, course of disease, type of disease, and sexuality in WD. METHODS A total of 46 WD patients and 40 health controls (HC) were recruited in this study. A total of 42 WD patients were divided into different groups according to clinical manifestations, course of disease, sexuality, and brain MRI lesions. We employed the Global Assessment Scale to assess neurological severity of WD patients. All WD patients and HC underwent retinal OCT to assess the thickness of inner limiting membrane (ILM) layer to retinal pigment epithelium layer and inner retina layer (ILM to inner plexiform layer, ILM-IPL). RESULTS Compared to HWD, NWD had thinner superior parafovea zone (108.07 ± 6.89 vs. 114.40 ± 5.54 μm, p < .01), temporal parafovea zone (97.17 ± 6.65 vs. 103.60 ± 4.53 μm, p < .01), inferior parafovea zone (108.114 ± 7.65 vs. 114.93 ± 5.84 μm, p < .01), and nasal parafovea zone (105.53 ± 8.01 vs. 112.10 ± 5.44 μm, p < .01) in inner retina layer. Course of disease influenced the retina thickness. Male patients had thinner inner retina layer compared to female patients. CONCLUSION Our results demonstrated that WD had thinner inner retina layer compared to HC, and NWD had thinner inner retina layer compared to HWD. We speculated the thickness of inner retina layer may be a potential useful biomarker for NWD.

Abstract
Wilson's disease (WD, MIM#277900) is an autosomal recessive disorder resulting in copper excess caused by biallelic variants in the ATP7B gene (MIM#606882) encoding a copper transporting P-type ATPase. ATP7B variants of unknown significance (VUS) are detected frequently, sometimes impeding a clear diagnosis. Functional analyses can help to classify these variants as benign or pathogenic. Additionally, variants already classified as (likely) pathogenic benefit from functional analyses to understand their pathomechanism, thus contribute to the development of personalized treatment approaches in the future. We described clinical features of six WD patients and functionally characterized five ATP7B missense variants (two VUS, three yet uncharacterized likely pathogenic variants), detected in these patients. We determined the protein level, copper export capacity, and cellular localization in an in vitro model and potential structural consequences using an ATP7B protein model based on AlphaFold. Our analyses give insight into the pathomechanism and allowed reclassification for the two VUS to likely pathogenic and for two of the three likely pathogenic variants to pathogenic.

Abstract
BACKGROUND Wilson disease (WD) is a hereditary disorder of copper metabolism, caused by mutations in the ATP7B gene. There are more than 1000 pathogenic variants identified in ATP7B. R778L is the most common ATP7B mutation in China. METHODS To estimate whether R778L is associated with the onset age of WD and other clinical variables. Genotyping results of ATP7B gene were collected in our 22 patients with WD. We then conducted a systematic review and meta-analysis in databases, using the keywords Wilson disease and R778L mutation. RESULTS After the screening, a total of 23 studies were included, including 3007 patients with WD. Patients with R778L mutation presented at an earlier age (standardized mean difference [SMD] = -0.18 [95% confidence interval, -0.28 to 0.08], P = 0.0004) and had lower ceruloplasmin concentration (SMD = -0.21 [95% confidence interval, -0.40 to -0.02], P = 0.03) than the patients without the R778L mutation. However, sex (odds ratio [OR] = 1.07 [95% confidence interval, 0.89 to 1.29], P = 0.32) and first presentation were not associated with R778L mutation in WD (hepatic: OR = 1.37 [95% confidence interval, 0.87 to 2.16, P = 0.17; neurological: OR = 0.79 [95% confidence interval, 0.48 to 1.30, P = 0.35; mix: OR = 1.04 [95% confidence interval, 0.42 to 2.53, P = 0.87; asymptomatic/others: OR = 1.98 [95% confidence interval, 0.49 to 7.96, P = 0.34). CONCLUSIONS Our results indicated that the R778L mutation is associated with an earlier presentation and lower ceruloplasmin concentration in China.

Abstract
Wilson's disease is an autosomal recessive disorder arising from pathogenic variants in the Atp7b gene on chromosome 13. The defective translated ATPase copper (Cu) transport protein produced leads to Cu accumulation, initially affecting the liver but eventually affecting other cells. It is just over 20 years since the last Best Practice on this topic in this journal. This review is an update on this, covering new disease biomarkers, pathogenesis, assumptions around clinical features and developments in therapy.

Abstract
BACKGROUND A substantial proportion of Wilson's disease (WD) patients exhibit residual neurological symptoms. Data on the prognostic value of initial clinical features and treatment choices in WD patients compliant to the therapy is relatively sparse. AIM The aim of the present study was to identify predictors of the long-term outcome of patients with WD with good treatment adherence. METHODS Forty patients with neurological form of WD were evaluated before the de-coppering treatment initiation (based on the medical records) and after mean 15.25 ± 11.24 years of the stable treatment. Severity of neurological symptoms were assessed with a tier two of Global Assessment Scale (GAS) for Wilson's Disease. RESULTS The most frequent symptoms prior to treatment initiation were dysarthria (90%), tremor (90%), clumsiness (67.5%), depression (67.5%), and gait disturbance (62.5%). Significant decrease in the frequency of dysarthria, clumsiness, tremor, gait disturbance, postural instability and an improvement in school/work performance were observed after the long-term treatment, while frequency of dysphagia, drooling, bradykinesia and rigidity, dystonic and choreatic features did not change. Overall symptom severity decreased over time. Presence of dystonia before treatment initiation was the only identified predictor of worse residual GAS score. Greater severity of residual dystonia was associated with female gender and longer disease duration. CONCLUSION Although patients with neurological form of WD compliant to de-coppering treatment had favorable disease outcome, a significant burden of residual neurological symptoms was observed after the long-term follow-up. Dystonia at disease onset was the only identified predictor of the worse long-term outcome.

Abstract
The metabolic disorder Wilson's disease (WD) is caused by copper accumulation in the tissues due to a biallelic pathogenic mutation of the gene ATP7B, encoding intracellular copper transporter ATPase-7B. As copper is a redox active metal; aberrations in its homeostasis may create favourable conditions for superoxide-yielding redox cycling and oxidative damage to the cells. We tried to characterise antioxidant defence in WD patients and to evaluate whether it is related to liver function. The blood glutathione concentration, the activity of manganese-SOD (MnSOD), catalase (Cat), glutathione peroxidase, and glutathione S-transferase glutathione (GST), and serum antioxidant potential (AOP-450) were measured in WD treatment-naive patients and healthy controls and correlated with clinical data. The blood glutathione concentration, the activity of MnSOD, Cat, glutathione peroxidase, and GST and AOP-450 are significantly decreased in WD patients. There was a positive correlation of AOP-450 with AST. Moreover, the Cat and GST activity as well as AOP-450 strongly correlated with parameters of synthetic liver function. MnSOD activity correlated positively with ALT and AST.The blood glutathione concentration, the activity of MnSOD, Cat, glutathione peroxidase, and GST and AOP-450 are significantly decreased in WD patients.

MnSOD activity correlated positively with ALT and AST. Liver injury in course of WD is linked with decreased antioxidant capacity.

J Pharm Biomed Anal 2023; 229:115355. [PMID: 37018958 DOI: 10.1016/j.jpba.2023.115355] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Revised: 03/19/2023] [Accepted: 03/20/2023] [Indexed: 03/28/2023]
Abstract
OBJECTIVE To investigate the metabolic mechanisms of Chinese and Western medicines on the metabolic network of striatal injury in a copper-loaded rat model of Wilson disease (WD) from a metabolomic perspective. METHODS We divided 60 rats into 4 groups of 15 rats each according to a random number table, namely the control group, the model group, the Bushen Huoxue Huazhuo Recipe group, and the penicillamine group, and subsequently replicated the WD copper-loaded rat model according to the literature method for a total of 12 weeks. From the 7th week onwards, each intervention group was given an equivalent dose of the corresponding drug, and the control and model groups were given an equal volume of saline gavage until the end of the model replication. We used 1H NMR metabolomics techniques combined with multivariate statistical methods to describe the changes in the striatal metabolic profile of nerve injury in Wilson's disease and to analyze the effect of different treatments on their biomarker interventions. RESULTS Nerve cell damage was evident in the WD copper-loaded rat model and could be reduced to varying degrees by different methods of intervention in the striatal nerve cells. The content of glycine, serine metabolism, and valine metabolism decreased in WD copper-loaded rat model; aspartate content increased after penicillamine intervention; glycolytic metabolism, valine metabolism, taurine metabolism, and tyrosine metabolism increased in the group of Bushen Huoxue Huazhuo Recipe. CONCLUSION Different intervention methods of Chinese and Western medicine affect aspartate, glycolysis, taurine, tyrosine, valine, and carbon metabolism in striatal tissues of WD copper-loaded rats, and can regulate the metabolism of small molecules, which in turn have certain repairing effects on nerve damage in WD copper-loaded rats.

Abstract
Copper is an essential micronutrient and also a regulated product used in organic and in conventional farming pest management. Both deficiency and excessive exposure to copper can have adverse health effects. In this Scientific Opinion, the EFSA 2021 harmonised approach for establishing health-based guidance values (HBGVs) for substances that are regulated products and also nutrients was used to resolve the divergent existing HBGVs for copper. The tightly regulated homeostasis prevents toxicity manifestation in the short term, but the development of chronic copper toxicity is dependent on copper homeostasis and its tissue retention. Evidence from Wilson disease suggests that hepatic retention is indicative of potential future and possibly sudden onset of copper toxicity under conditions of continuous intake. Hence, emphasis was placed on copper retention as an early marker of potential adverse effects. The relationships between (a) chronic copper exposure and its retention in the body, particularly the liver, and (b) hepatic copper concentrations and evidence of toxicity were examined. The Scientific Committee (SC) concludes that no retention of copper is expected to occur with intake of 5 mg/day and established an Acceptable Daily Intake (ADI) of 0.07 mg/kg bw. A refined dietary exposure assessment was performed, assessing contribution from dietary and non-dietary sources. Background copper levels are a significant source of copper. The contribution of copper from its use as plant protection product (PPP), food and feed additives or fertilisers is negligible. The use of copper in fertilisers or PPPs contributes to copper accumulation in soil. Infant formula and follow-on formula are important contributors to dietary exposure of copper in infants and toddlers. Contribution from non-oral sources is negligible. Dietary exposure to total copper does not exceed the HBGV in adolescents, adults, elderly and the very elderly. Neither hepatic copper retention nor adverse effects are expected to occur from the estimated copper exposure in children due to higher nutrient requirements related to growth.

Abstract
Wilson disease and alpha1-antitrypsin deficiency are two rare genetic diseases that may impact predominantly the liver and/or the brain, and the liver and/or the lung, respectively. The early diagnosis of these diseases is important in order to initiate a specific treatment, when available, ideally before irreversible organ damage, but also to initiate family screening. This review focuses on the non-invasive diagnostic tests available for clinicians in both diseases. These tests are crucial at diagnosis to reduce the potential diagnostic delay and assess organ involvement. They also play a pivotal role during follow-up to monitor disease progression and evaluate treatment efficacy of current or emerging therapies.

Clinical and genetic characterization of pediatric patients with Wilson's disease from Yunnan province where ethnic minorities gather. Front Genet 2023; 14:1142968.

Abstract
Background: Wilson's disease (WD) is an autosomal recessive disease that is caused by mutations in the ATP7B (a copper-transporting P-type ATPase) gene. The disease has a low prevalence and is characterized by a copper metabolism disorder. However, various characteristics of the disease are determined by race and geographic region. We aimed to discover novel ATP7B mutations in pediatric patients with WD from Yunnan province, where there is a high proportion of ethnic minorities. We also performed a comprehensive analysis of ATP7B mutations in the different ethnic groups found in Southwest China. Methods: We recruited 45 patients who had been clinically diagnosed with WD, from 44 unrelated families. Routine clinical examinations and laboratory evaluations were performed and details of age, gender, ethnic group and symptoms at onset were collected. Direct sequencing of the ATP7B gene was performed in 39 of the 45 patients and their families. Results: In this study, participants came from seven different ethnic groups in China: Han, Bai, Dai, Zhuang, Yi, Hui and Jingpo. Three out of ten patients from ethnic minorities presented with elevated transaminases, when compared to the majority of the Han patients. Forty distinct mutations (28 missense, six splicing, three non-sense, two frameshift and one mutation of uncertain significance) were identified in the 39 patients with WD. Four of the mutations were novel and the most frequent mutation was c.2333G > T (p.R778L, allelic frequency: 15.38%). Using the phenotype-genotype correlation analysis, patients from ethnic minorities were shown to be more likely to have homozygous mutations (p = 0.035) than Han patients. The patients who carried the c.2310C > G mutation had lower serum ceruloplasmin levels (p = 0.012). In patients with heterozygous mutations, c.3809A > G was significantly associated with ethnic minorities (p = 0.042). The frequency of a protein-truncating variant (PTV) in Han patients was 34.38% (11/32), while we did not find PTV in patients from ethnic minorities. Conclusion: This study revealed genetic defects in 39 pediatric patients with WD from Yunnan province. Four novel mutations were identified and have enriched the WD database. We characterized the genotypes and phenotypes in different minorities, which will enhance the current knowledge on the population genetics of WD in China.

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
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
BACKGROUND AND AIMS Wilson disease (WD) has diverse presentations that frequently mimic other liver diseases. Distinguishing WD from non-alcoholic fatty liver disease (NAFLD) and autoimmune hepatitis (AIH), can be difficult and has critical implications for medical management. This study aimed to examine the utility of histological features of WD in children compared to those with NAFLD and AIH. METHODS A review of liver biopsy slides was performed in children with a clinical and/or genetic diagnosis of WD, seen at the Hospital for Sick Children between 1981 and 2019 and compared to controls with NAFLD and AIH. 37 children with WD and 37 disease controls (20 NAFLD; 17 AIH) were included. Three pathologists, blind to clinical details and diagnosis, reviewed all liver biopsies to reach consensus. Clinical and histopathologic features were compared between groups. RESULTS Most WD cases displayed steatosis or steatohepatitis on histology (34/37), active AIH-pattern in 1 and inactive cirrhosis in 2 cases. Electron microscopy (EM) findings of mitochondrial abnormalities including dilated tips of cristae, pleomorphism, membrane duplication and dense matrix were more frequent in the WD group as compared to disease controls (p < 0.0001). In WD, dilated tips of mitochondrial cristae had a sensitivity of 91% and specificity of 86%, best among EM features. CONCLUSIONS Light microscopic findings display considerable overlap among children with WD, NAFLD and AIH. Ultrastructural findings of mitochondrial abnormalities are important to distinguish WD from NAFLD and AIH. EM examination should be considered essential in the diagnostic work-up of paediatric liver biopsies.

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 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.

Synonymous mutation in adenosine triphosphatase copper-transporting beta causes enhanced exon skipping in Wilson disease. Hepatol Commun 2022; 6:1611-1619. [PMID: 35271763 PMCID: PMC9234614 DOI: 10.1002/hep4.1922] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2021] [Revised: 11/25/2021] [Accepted: 12/22/2021] [Indexed: 12/21/2022] Open
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
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 disease (WD) is a potentially fatal genetic disorder with a broad spectrum of phenotypic presentations. Inactivation of the copper (Cu) transporter ATP7B and Cu overload in tissues, especially in the liver, are established causes of WD. However, neither specific ATP7B mutations nor hepatic Cu levels, alone, explain the diverse clinical presentations of WD. Recently, the new molecular details of WD progression and metabolic signatures of WD phenotypes began to emerge. Studies in WD patients and animal models revealed the contributions of non-parenchymal liver cells and extrahepatic tissues to the liver phenotype, and pointed to dysregulation of nuclear receptors (NR), epigenetic modifications, and mitochondria dysfunction as important hallmarks of WD pathogenesis. This review summarizes recent advances in the characterization of WD pathophysiology and discusses emerging targets for improving WD diagnosis and treatment.

Abstract
Abstract
Background
Wilson’s disease (WD) is an autosomal recessive disorder of copper metabolism caused by ATP7B (encoding a copper-transporting P-type ATPase) variants that shows various characteristics according to race and geographical region. This study was aimed to provide a comprehensive analysis of ATP7B variants in China and to investigate a plausible role of common variants in WD manifestations.
Methods
A total of 1366 patients (1302 index patients and 64 siblings) clinically diagnosed with WD (Leipzig score ≥ 4) were recruited. They underwent ATP7B gene sequencing and information of age and symptoms at onset was collected. The genotype–phenotype correlation was assessed in the index patients who were examined with two pathogenic variants and onset with hepatic (n = 276) or neurologic (n = 665) symptoms.
Results
We identified 294 potentially pathogenic ATP7B variants (112 truncating, 174 missense, 8 in-frame) in the 1302 index patients, including 116 novel variants. The most frequent variant was c.2333G>T (R778L, allele frequency: 28.96%), followed by c.2975C>T (P992L, 13.82%), c.2621C>T (A874V, 5.99%), c.2755C>G (R919G, 2.46%), and c.3646G>A (V1216M, 1.92%). In 1167 patients, both pathogentic variants were identified, of which 532 different variant combinations were found. By binary logistic regression analysis, the factor associated with neurological presentation was high age-at-onset, but not sex, protein-truncating variant (PTV), or the common missense variants (R778L, P992L, and A874V). In the neurological group, low age-at-onset was a factor associated with dystonia, gait abnormality, and salivation; high age-at-onset was a factor associated with tremor; and the sex, low age-at-onset and A874V were independent factors associated with dysarthria. In addition, PTV, R778L, and P992L were predominant in early-onset patients, whereas A874V was predominant in late-onset patients, and patients with R778L/A874V genotype displayed a higher age-at-onset than patients with R778L/R778L or R778L/P992L genotype.
Conclusions
Our work expanded the ATP7B variant spectrum and highlighted the differences among patients with WD in age-at-onset and ATP7B variants, which may provide some valuable insights into the diagnosis, counseling, and treatment of patients with WD.

Abstract
Objective: The aim of the study was to develop the early diagnostic criteria for Wilson’s disease (WD) in young children in southern China by using alanine aminotransferase (ALT) elevation as the first manifestation.Methods: A cross-sectional retrospective analysis of the clinical data and genetic test results of children with WD in southern China in the past 4 years and the follow-up of their short-term prognosis were performed in this study.Results: A total of 30 children (5.08 ± 2.06 years old) with elevated ALT as the first manifestation of WD in southern China were enrolled in this study, including 14 females and 16 males. Specifically, in all of the 30 cases (100%), the serum ceruloplasmin (CP) level was decreased, whereas the 24-h urinary copper level was increased. The genetic mutation test of the ATP7B gene was used to confirm the diagnosis. In particular, the two mutation sites, including p.R778L and p.I1148T, had the highest mutation frequencies, approximately 23.0 and 10.7%, respectively. Through follow-up, most of the children had good recovery.Conclusion: Early diagnosis and treatment of WD would substantially increase the survival rate and have a better prognosis. In addition, in 5-year-old children from southern China, early diagnosis could be performed quickly by referring to the following three parameters: elevated ALT, decreased ceruloplasmin level, and increased 24-h urinary copper level. It lays a foundation for further studies with a larger sample size.

Abstract
Wilson disease (WD) is an autosomal recessive disorder caused by mutations of the ATP7B gene, with a reported prevalence of 1:30,000-50,000. ATP7B encodes an enzyme called transmembrane copper-transporting ATPase, which is essential for copper incorporation into ceruloplasmin and for copper excretion into the bile. A lack or dysfunction of this enzyme results in a progressive accumulation of copper in several organs, especially in the liver, the nervous system, corneas, kidneys, and heart. Children with WD can present with asymptomatic liver disease, cirrhosis, or acute liver failure, with or without neurological and psychiatric symptoms. Approximately 20%-30% of WD patients present with ALF, while most of the other patients have chronic progressive hepatitis or cirrhosis if untreated. Although genetic testing has become a more important diagnostic tool for WD, the diagnosis remains based on both clinical features and laboratory investigations. The aims of treatment are to reduce copper levels and prevent its accumulation in the liver and other organs, especially in the central nervous system. Liver transplantation in WD is a life-saving option for patients presenting with liver failure and encephalopathy. For WD patients treated with chelating agents, adherence to the therapy is essential for long-term success. In this review, we also address specific issues in young adults as compared to children.

Abstract
BACKGROUND Hepatolenticular degeneration (HLD), also known as Wilson disease (WD), is a rare autosomal-recessive hereditary disease, which is often missed and misdiagnosed because of its various clinical manifestations. And WD is even more rare with giant subarachnoid cysts. In this report, we will provide a case of WD with an intracranial arachnoid cyst (IAC). CASE DESCRIPTION A 27-year-old woman was hospitalized in a traditional Chinese medicine hospital in Guangzhou with the first manifestation of a "slight involuntary tremor of her left upper limb". There was no improvement after acupuncture treatment, and then she was transferred to another large general hospital in Guangzhou. MRI examination of the head showed "left frontal, parietal and temporal giant subarachnoid cyst" and the patient underwent "left frontotemporal arachnoid cyst celiac shunt operation." After the operation, the patient's left limb shaking remained unchanged. Subsequently, the patient was referred to another big hospital in Guangzhou, considered "Parkinson's disease," and given "Medopa, Antan" and other treatments. However, the patient's limb shaking continued to increase and gradually developed to the extremities. At last, the patient was referred to our hospital, combined with the medical history, neurological signs, and auxiliary examination results, improve the examination of corneal K-F ring, blood ceruloplasmin, gene screening, and other tests; the diagnosis was confirmed as hepatolenticular degeneration. CONCLUSION After expelling copper and symptomatic treatment, the condition is improved.
