    威尔逊病是一种常染色体隐性遗传疾病,由于铜代谢缺陷,导致铜的异常积累和肝脏损伤,大脑,肾脏和其他器官。
    为了描述临床特征,儿童Wilson病的实验室调查和结果。
    通过回顾2018年1月至2023年3月之间的医疗记录,在印度南部一家三级保健医院的儿科部门进行了一项回顾性观察性研究。通过低血清铜蓝蛋白和/或高尿铜排泄的存在以及临床和眼科特征,证实了威尔逊病的诊断。
    共32例。演示时的平均(SD)年龄为110(36)个月,M:F比为1.6:1。在19(60%)患者中观察到孤立的肝脏受累,而13(40%)患者有神经系统表现,无论是作为一个孤立的实体或结合肝脏表现。在31例(96%)患者中检测到低血清铜蓝蛋白水平。所有患者的尿铜水平均升高。21例患者开始接受D青霉胺治疗,而11例患者接受锌联合螯合疗法治疗。18例患者(56%)接受定期随访。
    儿童Wilson病的临床表现多样,从较常见的肝脏或神经系统表现到较不常见的非典型疾病。诊断基于临床和眼科特征,并结合低铜蓝蛋白和高尿铜形式的生化异常。大多数患者可以用螯合疗法进行医学管理。
    UNASSIGNED: Wilson disease is an autosomal recessive disorder owing to defective copper metabolism which causes abnormal accumulation of copper and damage to the liver, brain, kidneys and other organs.
    UNASSIGNED: To describe the clinical features, laboratory investigations and outcome of Wilson disease in children.
    UNASSIGNED: A retrospective observational study was conducted in the paediatric department of a tertiary- care hospital in South India by reviewing medical records between January 2018 and March 2023. The diagnosis of Wilson disease was confirmed by the presence of low serum ceruloplasmin and/or high urine copper excretion in combination with clinical and ophthalmological features.
    UNASSIGNED: A total of 32 cases were analysed. The mean (SD) age at presentation was 110 (36) months with a M:F ratio of 1.6:1. Isolated hepatic involvement was seen in 19 (60%) patients while 13 (40%) patients had a neurological presentation, either as an isolated entity or in combination with hepatic manifestations. Low serum ceruloplasmin levels were detected in 31 (96%) patients. Urine copper levels were elevated in all patients. Twenty-one patients were commenced on D penicillamine while 11 patients were treated with a combination chelation therapy with zinc. Eighteen patients (56%) were on regular follow-up.
    UNASSIGNED: The clinical presentation of Wilson disease in children is diverse, varying from the more common hepatic or neurological manifestations to the less common atypical forms of the disease. Diagnosis is based on clinical and ophthalmological features in combination with biochemical abnormalities in the form of low ceruloplasmin and high urinary copper. The majority of patients can be medically managed with chelation therapy.

    OBJECTIVE: Aim: To determine the effect of the developed complex treatment of patients with peritonitis on the dynamics of humoral factors of nonspecific reactivity in the course of the disease.
    METHODS: Materials and Methods: The study included 124 patients with toxic and terminal stages of peritonitis, who were divided into 3 groups. Group I (main) included 39 patients whose complex treatment included cytochrome C. Group II (main) included 41 patients whose complex treatment included cytochrome C and a solution containing levocarnitine and arginine hydrochloride. The comparison group comprised 44 patients who did not receive the specified drugs. The patients underwent determination of the levels of fibronectin, ceruloplasmin, and procalcitonin in the serum during the course of the disease.
    RESULTS: Results: In patients of the I and II main groups, the use of the proposed treatment contributed to the optimization of the production of acute phase proteins: a decrease in procalcitonin production during the study, optimization of ceruloplasmin and fibronectin production, especially in the II main group. In patients of the comparison group, decompensation in the production of humoral inflammatory factors was determined, associated with a significant increase in fibronectin production, a decrease in ceruloplasmin content, and an increase in procalcitonin throughout the entire period.
    CONCLUSIONS: Conclusions: The use of cytochrome C and a solution containing levocarnitine and arginine hydrochloride in the complex treatment of patients with disseminated peritonitis helps to optimize the production of acute phase proteins, which leads to a decrease in inflammation and the preservation of factors of nonspecific humoral activity at a subcompensated level.

    作为阿尔茨海默病(AD)的潜在治疗方法,已经对淀粉样蛋白-β(Aβ)种类的产生的减少进行了深入的研究。然而,Aβ物种的降解,另一种潜在的有益方法,很少探索。
    研究多铜氧化酶(MCOS)在降解Aβ肽中的潜力及其对AD治疗的潜在益处。
    我们通过电泳研究了MCO的降解效率,并使用全内反射荧光显微镜验证了铜蓝蛋白(CP)-Aβ相互作用,荧光光度计,和荧光偏振测量。我们还通过使用诱导的多能干(iPS)神经元细胞和脑切片的电生理分析研究了抗坏血酸氧化酶(AO)的治疗效果。
    我们发现CP,人类血液中重要的MCO,可以降解Aβ肽。我们还发现其他MCO也可以诱导Aβ降解。值得注意的是,我们发现,在测试的MCO中,AO的降解作用最强。使用iPS神经元细胞,我们观察到AO可以挽救Aβ寡聚体诱导的神经元毒性。此外,我们对脑切片的电生理分析表明,AO可以预防Aβ诱导的海马突触传递缺陷.
    据我们所知,我们的报告是第一个证明MCOS具有降解肽/蛋白质的功能。需要进一步的研究来探索MCOS对未来AD治疗的可能益处。
    UNASSIGNED: Reduction of the production of amyloid-β (Aβ) species has been intensively investigated as potential therapeutic approaches for Alzheimer\'s disease (AD). However, the degradation of Aβ species, another potential beneficial approach, has been far less explored.
    UNASSIGNED: To investigate the potential of multi-copper oxidases (MCOs) in degrading Aβ peptides and their potential benefits for AD treatment.
    UNASSIGNED: We investigated the degradation efficiency of MCOs by using electrophoresis and validated the ceruloplasmin (CP)-Aβ interaction using total internal reflection fluorescence microscopy, fluorescence photometer, and fluorescence polarization measurement. We also investigated the therapeutic effect of ascorbate oxidase (AO) by using induced pluripotent stem (iPS) neuron cells and electrophysiological analysis with brain slices.
    UNASSIGNED: We discovered that CP, an important MCO in human blood, could degrade Aβ peptides. We also found that other MCOs could induce Aβ degradation as well. Remarkably, we revealed that AO had the strongest degrading effect among the tested MCOs. Using iPS neuron cells, we observed that AO could rescue neuron toxicity which induced by Aβ oligomers. In addition, our electrophysiological analysis with brain slices suggested that AO could prevent an Aβ-induced deficit in synaptic transmission in the hippocampus.
    UNASSIGNED: To the best of our knowledge, our report is the first to demonstrate that MCOs have a degrading function for peptides/proteins. Further investigations are warranted to explore the possible benefits of MCOs for future AD treatment.

    Wilson病是一种罕见的遗传性疾病,其特征是由于ATP-7B基因突变导致铜代谢异常。该病例报告详细介绍了一名14岁的男性儿童表现出严重的广泛性肌张力障碍,刚性,肌阵挛性抽搐,构音障碍,唾液流口水过多.在眼科检查期间,确定了Kayser-Fleischer戒指。皮质和皮质下区域的对称高强度,包括基底神经节和脑干,在脑磁共振成像(MRI)上发现。此外,观察到双侧额顶区的扩散限制。威尔逊病的诊断通过进一步的诊断评估得到证实,如血清铜蓝蛋白水平和尿铜排泄。用青霉胺开始治疗,抗惊厥药,和支持性措施,导致三个月的随访期后部分恢复。该病例强调了在威尔逊病中识别非典型MRI脑部发现的重要性,这有助于早期诊断和适当的管理,以防止不可逆的神经损伤。
    Wilson\'s disease is a rare genetic disorder characterized by abnormal copper metabolism due to mutations in the ATP-7B gene. This case report details the presentation of a 14-year-old male child exhibiting severe generalized dystonia, rigidity, myoclonic jerks, dysarthria, and excessive salivary drooling. During ophthalmic examination, Kayser-Fleischer rings were identified. Symmetrical hyperintensities in cortical and subcortical areas, including the basal ganglia and brainstem, were noted on brain magnetic resonance imaging (MRI). Additionally, diffusion restriction in the bilateral fronto-parietal region was observed. The diagnosis of Wilson\'s disease was confirmed through further diagnostic assessments, such as serum ceruloplasmin levels and urine copper excretion. Treatment was initiated with penicillamine, anticonvulsants, and supportive measures, resulting in partial recovery after a three-month follow-up period. This case emphasizes the significance of identifying atypical MRI brain findings in Wilson\'s disease, which aids in early diagnosis and appropriate management to prevent irreversible neurological damage.

    铜蓝蛋白血症(ACP)是一种罕见的遗传性疾病,由于CP(铜蓝蛋白)基因突变而在成年期出现,导致铁积累和神经变性。临床上,ACP有一系列的症状,包括轻度小细胞性贫血,糖尿病,肝病,视网膜病变,进行性神经系统症状,如小脑共济失调,非自愿运动,帕金森病,情绪和行为障碍,和认知障碍。我们介绍了一名53岁的女性,有一级血缘史和一个患有贫血的姐妹。六岁的时候,她出现了虚弱,导致需要输血和铁治疗的急性溶血性贫血多次住院。她表现出后来的记忆障碍,减缓了理解,社会退出,和学校停课。51岁时,她出现了步态障碍,无法解释的跌倒,和认知能力下降。一年后,头颅CT显示慢性双侧硬膜下血肿。53岁时,她有无音,右偏瘫,扩散刚度,口腔肌张力障碍,动眼神经麻痹,和智力退化。MRI显示浅表皮质和软脑膜含铁血黄素沉积以及各个深部脑区的双侧信号异常。EEG显示阵发性异常,腹部MRI显示肝铁超负荷。实验室测试证实ACP。该病例突出了ACP的罕见和严重的神经系统和全身表现,强调早期诊断和干预此类退行性疾病以预防不可逆的神经系统并发症的重要性。
    Aceruloplasminemia (ACP) is a rare genetic disorder that manifests in adulthood due to mutations in the CP (ceruloplasmin) gene, causing iron accumulation and neurodegeneration. Clinically, ACP presents with a range of symptoms, including mild microcytic anemia, diabetes mellitus, liver disease, retinopathy, progressive neurological symptoms such as cerebellar ataxia, involuntary movements, parkinsonism, mood and behavior disorders, and cognitive impairment. We present the case of a 53-year-old female with a history of first-degree consanguinity and a sister with anemia. At six years old, she developed asthenia, leading to multiple hospitalizations for acute hemolytic anemia requiring transfusions and iron therapy. She exhibited later memory disturbances, slowed comprehension, social withdrawal, and school discontinuation. At the age of 51, she developed gait disturbances, unexplained falls, and cognitive decline. One year later, cranial CT revealed a chronic bilateral subdural hematoma. On admission at 53, she had anarthria, right hemiparesis, diffuse rigidity, mouth dystonia, oculomotor paralysis, and intellectual deterioration. MRI showed superficial cortical and leptomeningeal hemosiderin deposits and bilateral signal anomalies in various deep brain regions. EEG revealed paroxysmal anomalies and abdominal MRI indicated hepatic iron overload. Laboratory tests confirmed ACP. This case highlights the rare and severe neurological and systemic manifestations of ACP, emphasizing the importance of early diagnosis and intervention in such degenerative diseases to prevent irreversible neurological complications.

    背景:威尔逊氏病(WD)是一种罕见的常染色体隐性遗传疾病,可导致铜循环和排泄受损。WD的最初表现在临床上有所不同,这使得早期诊断非常困难。睡眠障碍被描述为WD的常见症状,但最初的表现是罕见的。
    方法:本研究旨在介绍一名以急性失眠为首发表现的WD患者。颅磁共振成像显示双侧壳核和尾状核广泛病变,call体压力区,中脑,还有Pons.有趣的是,罕见但特征性的WD体征,比如大熊猫的脸,“在这种情况下显示。通过降低的铜蓝蛋白水平和ATP7B(腺苷三磷酸酶铜转运β多肽)基因突变进一步建立WD诊断。
    结论:我们将急性失眠描述为一名21岁男性患者中WD的初始表现。及时诊断允许早期消除铜的药物治疗,具有很高的预后重要性,因为在这一点上,患者可能对治疗更有反应。
    BACKGROUND: Wilson\'s disease (WD) is a rare autosomal recessive disease that causes impaired copper circulation and excretion. The initial manifestations of WD vary clinically, which makes early diagnosis very difficult. Sleep disorders have been described as common symptoms of WD, but the initial manifestations are in rare cases.
    METHODS: This study aims to present a patient with acute insomnia as the initial manifestation of WD. Cranial magnetic resonance imaging showed extensive lesions in the bilateral putamen and caudate nucleus, pressure area of corpus callosum, midbrain, and pons. Interestingly, rare but characteristic signs of WD, such as \"face of the giant panda,\" were shown in this case. WD diagnosis was further established by decreased ceruloplasmin level and ATP7B (adenosine-triphosphatase copper transporting beta polypeptide) gene mutations.
    CONCLUSIONS: We describe acute insomnia as the initial manifestation of WD in a 21-year-old male patient. Timely diagnosis allows for early copper-eliminating pharmacotherapy, which is of high prognostic importance, as the patient may be more responsive to treatment at this point.

    一名女性青少年有9个月的进行性非自愿运动史,最初表现为手指震颤,并演变成四肢的摆动运动,导致在过去的4个月中无法行走。同时,她患上了构音障碍.神经,她表现出正常的力量,僵硬和轻快的深肌腱反射,足底反射下降。增强MRI显示双侧尾状叶高强度,基底神经节和脑桥,表明威尔逊病。肝功能检查和超声检查正常,而裂隙灯检查证实了Kayser-Fleischer环。血清铜蓝蛋白低,24小时尿铜升高(125.5mcg),全外显子组测序鉴定出杂合子ATP7B突变,确认诊断。孤立的神经系统受累而没有肝脏受累是一种极为罕见的表现,需要临床专业知识来描述威尔逊病作为一种可能的病因。
    A female adolescent presented with a 9 month history of progressive involuntary movements, initially manifesting as finger tremors and evolving into flinging motions of the extremities, resulting in an inability to walk over the last 4 months. Concurrently, she developed dysarthria. Neurologically, she exhibited normal power, rigidity and brisk deep tendon reflexes, with a downgoing plantar reflex. Contrast-enhanced MRI revealed hyperintensity in bilateral caudate lobes, basal ganglia and pons, indicative of Wilson\'s disease. Liver function tests and ultrasound were normal while Kayser-Fleischer rings were confirmed by slit lamp examination. Serum ceruloplasmin was low, 24-hour urine copper was elevated (125.5 mcg) and whole exome sequencing identified a heterozygous ATP7B mutation, confirming the diagnosis. Isolated neurological involvement without hepatic involvement is an extremely rare presentation and needs clinical expertise to delineate Wilson\'s disease as a possible aetiology.

    目的:评估Wilson病很复杂,既没有铜蓝蛋白,血清或尿铜,是可靠的。两个新指数,准确的非铜蓝蛋白铜(ANCC)和相对ANCC被开发并应用于71名患者的队列,作为威尔逊病注册研究的一部分。
    方法:使用强阴离子交换色谱与三重四极杆电感耦合等离子体质谱法,开发了元素铜蛋白形态用于全铜蓝蛋白定量。使用梯度洗脱分离血清蛋白,并使用氧反应模式和Cu-EDTA作为校准标准在m/z63(63Cu+)和48(32S16O+)下测量。通过从总血清铜减去铜蓝蛋白结合铜来计算ANCC,RelANCC是作为ANCC存在的总铜的百分比。
    结果:使用两种认证的参考材料建立了全铜蓝蛋白测量的准确性,平均回收率为94.2%。患者样品中含铜物质的总和与总铜浓度之间的回归分析是可接受的(斜率=0.964,截距=0,r=0.987)和差异图,铜的平均差为0.38μmol/L。血清铜浓度为0.48和3.20μmol/L时,全铜蓝蛋白的日内精密度分别为5.2和5.6%CV,浓度为0.80和5.99μmol/L时的中间精密度分别为6.4和6.4%CV。分别。全铜蓝蛋白的检测限(LOD)和定量下限(LLOQ)分别为0.08和0.27μmol/L,分别。
    结论:ANCC和相对ANCC是威尔逊病(WD)重要的新的诊断和监测生物标志物指标。
    OBJECTIVE: Assessment of Wilson disease is complicated, with neither ceruloplasmin, nor serum or urine copper, being reliable. Two new indices, accurate non-ceruloplasmin copper (ANCC) and relative ANCC were developed and applied to a cohort of 71 patients, as part of a Wilson Disease Registry Study.
    METHODS: Elemental copper-protein speciation was developed for holo-ceruloplasmin quantitation using strong anion exchange chromatography coupled to triple quadrupole inductively coupled plasma mass spectrometry. The serum proteins were separated using gradient elution and measured at m/z 63 (63Cu+) and 48 (32S16O+) using oxygen reaction mode and Cu-EDTA as calibration standard. The ANCC was calculated by subtraction of the ceruloplasmin bound copper from the total serum copper and the RelANCC was the percentage of total copper present as the ANCC.
    RESULTS: The accuracy of the holo-ceruloplasmin measurement was established using two certified reference materials, giving a mean recovery of 94.2 %. Regression analysis between the sum of the copper containing species and total copper concentration in the patient samples was acceptable (slope=0.964, intercept=0, r=0.987) and a difference plot, gave a mean difference for copper of 0.38 μmol/L. Intra-day precision for holo-ceruloplasmin at serum copper concentrations of 0.48 and 3.20 μmol/L were 5.2 and 5.6 % CV and the intermediate precision at concentrations of 0.80 and 5.99 μmol/L were 6.4 and 6.4 % CV, respectively. The limit of detection (LOD) and lower limit of quantification (LLOQ) for holo-ceruloplasmin were 0.08 and 0.27 μmol/L as copper, respectively.
    CONCLUSIONS: ANCC and Relative ANCC are important new diagnostic and monitoring biomarker indices for Wilson disease (WD).

    目的:本研究旨在说明中国女性卵巢储备功能减退的铜状态,尤其是铜的影响,铜蓝蛋白,非铜蓝蛋白结合铜(NCC)和CuZn超氧化物歧化酶(SOD1)。
    方法:本病例对照,横断面调查包括卵巢储备减少的女性(DOR组,n=35)和匹配的正常卵巢储备(NOR组,n=35)。血清中的铜水平,铜蓝蛋白,NCC,SOD1促卵泡激素,黄体生成素,雌二醇,睾丸激素,并对抗苗勒管激素进行了检测和分析。
    结果:血清铜浓度(60.88%),DOR组NCC(54.75%)和SOD1(54.75%)明显高于NOR组(均P<0.001),在大多数亚组中,三种标记物的浓度较高(P<0.001)。相关性分析验证了铜状态与卵巢功能受损的相关性。此外,线性回归分析显示,NCC和SOD1水平与抗苗勒管激素呈负相关(P<0.05或0.001)。
    结论:我们的探索发现铜显著增加,DOR中的NCC和SOD1级别,并建议可能的链接。铜状态有望作为DOR的预测标记。
    OBJECTIVE: This study aimed to illustrate the copper status of diminished ovarian reserve in Chinese women, especially the effects of copper, ceruloplasmin, non-ceruloplasmin-bound copper (NCC) and CuZn superoxide dismutase (SOD1).
    METHODS: This case-control, cross-sectional investigation included women with diminished ovarian reserve (DOR group, n = 35) and matched normal ovarian reserve (NOR group, n = 35). The serum levels of copper, ceruloplasmin, NCC, SOD1, follicle-stimulating hormone, luteinizing hormone, estradiol, testosterone, and anti-Müllerian hormone were tested and analyzed.
    RESULTS: The serum copper concentrations (60.88%), NCC (54.75%) and SOD1 (54.75%) in the DOR group were significantly higher than those in the NOR group (all P < 0.001), and the concentrations of the three markers were higher in most subgroups (P < 0.001). The correlation analysis verified the correlation between copper status and impaired ovarian function. Additionally, linear regression analysis showed that NCC and SOD1 levels were negatively correlated with anti-Müllerian hormone (P < 0.05 or 0.001).
    CONCLUSIONS: Our exploration found significant increases in copper, NCC and SOD1 levels in DOR and suggests a possible link. Copper status is expected to serve as the predictive marker for DOR.
