Background: In the autosomal recessive disorder of copper metabolism, Wilson's disease (WD), patients present hepatic, neurological, and psychiatric symptoms combined in different and unpredictable ways. Brain pathology primarily affects the basal ganglia and may cause movement, cognitive, affective, and behavioral disturbances. Personality traits have been rarely studied in the neurological form of the disease. Objective: To investigate whether patients with the neurological form of WD (WDn) have specific personality traits, especially those typical of frontobasal loop dysfunction. Methods: The personality of 29 adult WDn patients (without significant cognitive and psychiatric disorders) and 29 matched healthy controls was assessed using the Minnesota Multiphasic Personality Inventory (MMPI-2). Results: Compared to healthy individuals, patients with WDn scored higher on the following MMPI-2 scales: hypochondriasis, physical malfunctioning, bizarre sensory experiences, health concerns, and general health concerns, with no differentiation between patients and controls on the remaining MMPI-2 scales. Conclusions: Long-term treated patients with WDn did not appear to have any specific personality traits reflecting unambiguously frontobasal psychopathology, if self-report measurement is used. The more strongly exhibited features concerning their actual physical ailments and health anxiety, such as hypochondria, chronic fatigue, and poor psychophysical well-being, could result from psychological reactions to a chronic disabling brain disease. Further study of personality traits and personality disorders is warranted in patients with clearly defined forms of WD, using various measurement tools. Psychopathological disorders in different forms of WD warrant further studies.

Wilson's disease (WD) is an inherited disorder of copper metabolism with clinical symptoms related to pathological copper accumulation, which are mainly hepatic and/or neuropsychiatric. The disease is potentially treatable with pharmacological agents (chelators or zinc salts). As such, key factors for a favorable treatment outcome are early diagnosis and anti-copper treatment initiation as well as appropriate treatment monitoring for safety and efficacy. Despite the generally favorable outcome in most treated patients, almost 10% of the general population of WD patients and about 25% of patients in the group with initial neurological phenotype of disease experience early neurological deterioration. In almost 50% of patients with neurological symptoms, the symptoms persist. A search for new treatment modalities (e.g., gene therapy, molybdenum salts) aims to prevent early neurological deterioration as well as improve treatment outcomes. In addition to evaluating the clinical signs and symptoms of the disease, serum biomarkers for diagnosis and treatment monitoring are very important for WD management. Sensitive serum biomarkers of copper metabolism and liver injury are well described. However, there is a need to establish blood-based biomarkers of central nervous system (CNS) injury to help identify patients at risk of early neurological deterioration and aid in their monitoring. Based on the available literature and studies of WD patients, the authors reviewed serum biomarkers of CNS involvement in WD, as well as their potential clinical significance.

BACKGROUND:Treatment of Wilson's disease (WD), an inherited disease characterized by copper overload, is lifelong and there is the possibility that copper deficiency (CD) may occur. We systematically reviewed the literature to describe treatment patterns, symptoms and outcomes associated with CD.METHODS:Using preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines, the PubMed database was searched up to 6 April 2023.RESULTS:Across 17 articles, 20 cases of CD were described, most commonly (15 cases) in WD patients treated with zinc salts (ZS), less often on combined chelator and ZS therapy (3 cases), molybdate salts plus ZS (1), or molybdate alone (1). CD symptoms occurred insidiously, including sideroblastic anemia, neutropenia, axonal sensory neuropathy, posterior cord myelopathy and increased ratio of epileptic seizures (or epilepsy). CD diagnosis was based on symptoms and severely reduced urinary copper excretion (<20 µg/24 h [<0.3 µmol/24 h] on ZS, or <100 µg/24 h [<1.6 µmol/24 h] on chelators) with low total serum copper and ceruloplasmin.CONCLUSIONS:Awareness of CD and regular monitoring of copper metabolism is needed during WD treatment. Temporary cessation of anti-copper treatment usually reverses serum copper reductions as well as pancytopenia; however, some symptoms, especially neuropathy and myelopathy, may persist.

Liver fibrosis results from an imbalance between extracellular matrix formation and degradation. The background of liver fibrosis is chronic inflammation and subsequent microcirculation disturbance including microthrombosis. Platelets actively participate in liver fibrosis not only as a part of the clotting system but also by releasing granules containing important mediators. In fact, platelets may play a dual role in the pathophysiology of liver fibrosis as they are able to stimulate regeneration as well as aggravate the destruction of the liver. Recent studies revealed that antiplatelet therapy correlates with inhibition of liver fibrosis. However, liver impairment is associated with extensive coagulation disorders thus the safety of antiplatelet therapy is an area for detailed exploration. In this review, the role of platelets in liver fibrosis and accompanying hemostatic disorders are discussed. Additionally, results of animal and human studies on antiplatelet drugs in liver disorders and their potential therapeutic utility are presented.

INTRODUCTION:In Wilson's disease (WD), copper accumulation can result in neurological manifestations, particularly extrapyramidal symptoms. There are some data that the autonomic nervous system (ANS) may also be affected, and we aimed to systematically review available studies evaluating ANS dysfunction in WD. MATERIAL AND METHODS:We conducted a systematic review of the literature using the PubMed database (up to 31st August 2020), with search terms including "autonomic" and "function" and "Wilson's disease". RESULTS:Fourteen studies, including 297 patients with neurological, hepatic or psychiatric forms of WD were retrieved. The most frequent methods used for ANS evaluation were orthostatic tests, which were performed in seven studies, with a number of other tests less frequently used. The incidence of ANS abnormalities ranged from ~8% to 79.2%, depending on the evaluation method. ANS abnormalities in patients with WD were often clinically asymptomatic. The features of dysautonomia were more common among patients with neurological symptoms and ANS abnormalities were more common in patients with severe brain injury. Studies confirmed both sympathetic and parasympathetic ANS impairment. The pathophysiology of ANS damage was not clear but may result from central, peripheral nervous system and direct cardiac involvement. Clear improvements were observed in four studies after anti-copper therapy initiation. CONCLUSION:Both sympathetic and parasympathetic divisions of the ANS may be affected in WD. The observed ambiguities regarding ANS abnormalities in WD patients may arise from small study groups, differences in methodology, and a lack of comprehensive ANS evaluation; however, the results indicate that further studies are warranted.

Wilson’s disease is an autosomal–recessive disorder of copper metabolism caused by mutations in ATP7B and associated with neurological, psychiatric, ophthalmological and hepatic manifestations. Decoppering treatments are used to prevent disease progression and reduce symptoms, but neurological outcomes remain mixed. In this article, we review the current understanding of pathogenesis, biomarkers and treatments for Wilson’s disease from the neurological perspective, with a focus on recent advances. The genetic and molecular mechanisms associated with ATP7B dysfunction have been well characterised, but despite extensive efforts to identify genotype–phenotype correlations, the reason why only some patients develop neurological or psychiatric features remains unclear. We discuss pathological processes through which copper accumulation leads to neurodegeneration, such as mitochondrial dysfunction, the role of brain iron metabolism and the broader concept of selective neuronal vulnerability in Wilson’s disease. Delayed diagnoses continue to be a major problem for patients with neurological presentations. We highlight limitations in our current approach to making a diagnosis and novel diagnostic biomarkers, including the potential for newborn screening programmes. We describe recent progress in developing imaging and wet (fluid) biomarkers for neurological involvement, including findings from quantitative MRI and other neuroimaging studies, and the development of a semiquantitative scoring system for assessing radiological severity. Finally, we cover the use of established and novel chelating agents, paradoxical neurological worsening, and progress developing targeted molecular and gene therapy for Wilson’s disease, before discussing future directions for translational research.

Hepatic encephalopathy (HE) is a complex syndrome of neurological and psychiatric signs and symptoms that is caused by portosystemic venous shunting with or without liver disease irrespective of its etiology. The most common presentation of Wilson disease (WD) is liver disease and is frequently associated with a wide spectrum of neurological and psychiatric symptoms. The genetic defect in WD leads to copper accumulation in the liver and later in other organs including the brain. In a patient presenting with Wilsonian cirrhosis neuropsychiatric symptoms may be caused either by the metabolic consequences of liver failure or by copper toxicity. Thus, in clinical practice a precise diagnosis is a great challenge. Contrary to HE in neurological WD consciousness, is very rarely disturbed and pyramidal signs, myoclonus dominate. Asterixis and many other clinical symptoms may be present in both disease conditions and are quite similar. However details of neurological assessment as well as additional examinations could help in differential diagnosis.

Wilson's disease (WD) is a metabolic brain disease resulting from improper copper metabolism. Although pyramidal symptoms are rarely observed, subclinical injury is highly possible as copper accumulates in all brain structures. The usefulness of motor evoked potentials (MEPs) in pyramidal tracts damage evaluation still appears to be somehow equivocal. We searched for original papers assessing the value of transcranial magnetic stimulation elicited MEPs with respect to motor function of upper and lower extremity in WD. We searched PubMed for original papers evaluating use of MEPs in WD using key words: “motor evoked potentials Wilson's disease” and “transcranial magnetic stimulation Wilson's disease.” We found six articles using the above key words. One additional article and one case report were found while viewing the references lists. Therefore, we included eight studies. Number of patients in studies was low and their clinical characteristic was variable. There were also differences in methodology. Abnormal MEPs were confirmed in 20–70% of study participants. MEPs were not recorded in 7.6–66.7% of patients. Four studies reported significantly increased cortical excitability (up to 70% of patients). Prolonged central motor conduction time was observed in four studies (30–100% of patients). One study reported absent or prolonged central motor latency in 66.7% of patients. Although MEPs may be abnormal in WD, this has not been thoroughly assessed. Hence, further studies are indispensable to evaluate MEPs' usefulness in assessing pyramidal tract damage in WD.

Multiple sclerosis is a chronic demyelinating disease of the central nervous system that occurs primarily in young adults. There is no single diagnostic test to recognize the disease. The diagnostic criteria, based on clinical examination and laboratory tests, have changed considerably over time. The first guidelines involved only the results of the patient's neurological examination. The diagnostic criteria developed by Poser in 1983 were based largely on the results of additional tests, including visual evoked potentials and analysis of cerebrospinal fluid. The McDonald criteria, developed in 2001and updated in 2005 and 2010, reflected the diagnostic breakthrough caused by widespread use of magnetic resonance imaging (MRI). Currently, the diagnosis depends largely on the results of the MRI examination. An early diagnosis is particularly important for starting disease-modifying treatments.

Glucocorticosteroids (GS) are standard treatment of multiple sclerosis (MS) relapse, but no superiority of any commonly used doses is known. The aim of present study was to evaluate mRNA expression for two cytokines: IL-6 and IL-8. Ethylenediaminetetraacetic acid blood samples from 35 MS relapse patients were obtained before therapy, after 7, 14 days, and 3 months from treatment start (500 versus 1000 mg for 5 days). Significant neurological improvement measured with EDSS was independent to GS dose. Changes of mRNA cytokines expression were more evident in higher dose group but for IL-6 mainly in females.

Wilson's disease (WD) is an autosomal recessive disorder and the WD heterozygote carriers (Hzc) should not exhibit symptoms of the disease. The aim of this study was to assess 12 WD Hzc by brain Proton MR Spectroscopy. In three cases, the levels of caeruloplasmin, and in one case, serum copper, were below our normal range. In two Hzc the aspartate and alanine aminotransferase levels in the blood were slightly increased, however, no ultrasonographic liver changes were detected. The brain metabolite analysis showed a statistically significant higher mean ratio of Glx/Cr and Lip/Cr in MRS in Hzc in both the pallidum and thalami compared to control subjects. Our results suggest that WD Hzc may accumulate free copper in the basal ganglia.

The aim of this study was to determine the effectiveness of brain proton magnetic resonance spectroscopy ( 1 H‐MRS) for monitoring therapy in Wilson's disease (WD) patients. Voxels were located in the globus pallidus (right, left). We followed 17 newly diagnosed WD cases for 1‐year period. During this observation period, 6 neurological and 9 hepatic patients improved, while 2 neurological patients deteriorated. The pretreatment 1 H‐MRS analysis showed a statistically significant lower level of mI/Cr, NAA/Cr, and higher Lip/Cr in all WD patients with improvement compared with controls. In patients with hepatic signs, a statistically significant increase of mI/Cr and Glx/Cr was observed in the second (1 year posttreatment) 1 H‐MRS. In patients with neurological improvement after treatment in the follow‐up 1 H‐MRS, a statistically significant increase of NAA/Cr was noted. During neurological deterioration, a decrease of Glx/Cr and NAA/Cr was seen, in contrast to another neurologically impaired patient with liver failure exacerbation, where a decrease of mI/Cr and increase of Glx/Cr was observed. The alternations of NAA/Cr ratio in neurologically impaired patients and mI/Cr and Glx/Cr in patients with liver failure could be a sensitive marker of the clinical recovery and deterioration in those WD patients. 1 H‐MRS is a technique that can be used for accurate monitoring of treatment efficacy in WD patients. © 2008 Movement Disorder Society

Background: We recently discovered that APOE ε3/ε4 genotype in men and APOE ε2/ε3 genotype in women are associated with increased risk of death from ischemic stroke (IS). One of the main physiological roles of apolipoprotein E is participation in cholesterol metabolism. A significant association of low serum cholesterol level with increased risk of death from stroke was documented. So, we aimed to establish if an association exists between APOE genotype, serum cholesterol and 1-month mortality in IS. Methods: We studied 666 patients (330 men, 336 women) with a diagnosis of IS. Total serum cholesterol (TC) was measured with the method of Abbott Spectrum (USA). APOE genotyping was performed by PCR-RFLP method. Results:The highest frequency of low serum TC was associated with APOE ε2/ε3 genotype (both in men and in women). Low serum TC was associated with increased mortality rate only in women; this effect was evident only in females not possessing APOE ε2/ε3. Female patients with APOE ε2/ε3 genotype had high 1-month mortality rate independently from serum TC. In multiple regression analyses APOE ε3/ε4 genotype in men and APOE ε2/ε3 genotype in women predicted risk of death independently from serum TC and also from other potential pre- and post-stroke prognostic factors. Conclusion:APOE ε3/ε4 genotype in men and APOE ε2/ε3 in women are associated with increased 30-day mortality in stroke. This effect seems be independent from serum cholesterol.
