    UNASSIGNED: Preliminary evidence suggests that Qigong (QG), a mind-body therapy, may help address symptoms of multiple sclerosis (MS), but the heterogeneity of QG content and delivery may affect its feasibility, acceptability, and efficacy.
    UNASSIGNED: To survey researchers, clinicians, and QG instructors with experience working with people with MS to identify key components of MS-specific QG guidelines and protocols.
    UNASSIGNED: We conducted an online survey to identify QG forms and movements considered helpful for MS, reasons for selection, characteristics of effective learning environments, and recommended dosage and frequency of practice. Quantitative data were analyzed using summary statistics. Qualitative data were analyzed using reflexive thematic analysis.
    UNASSIGNED: Forty-seven experts, including QG instructors, clinicians, and QG and MS researchers, completed the survey. Respondents had a mean (SD) of 20 (11) years of QG teaching experience, 26 (12) years of clinical practice, 24 (9) years of QG research experience, 13 (5) years of MS research experience, and worked with at least 3 (2) people with MS. Approximately 125 QG forms/movements were recommended. Some forms were specifically recommended to address MS symptoms (e.g., emotional regulation, balance and coordination, muscle strength and flexibility, immune regulation, and circulation). Some respondents felt that any QG form could be beneficial if basic principles were met (e.g., intentional movement, posture, focused awareness, rhythmic breathing/movement, and a relaxed mind and body). Instructor qualities included the ability to convey information clearly, being caring and compassionate, proficient in QG, and having basic knowledge of MS. To promote confidence in learning QG, recommendations included having simple, easy-to-learn movements with modifications based on physical ability. We provide a sample protocol based on these recommendations.
    UNASSIGNED: This study provides expert guidance for developing a QG protocol for an MS population, including content and delivery recommendations.

    背景:尽管干扰素β(IFNβ)早已被批准为多发性硬化症(MS)的疾病改善疗法(DMT),流感样综合征(FLS)仍然是干扰素治疗的常见不良反应。鉴于昼夜节律在调节生理过程中的重要性,我们旨在评估接受IFNβ治疗的MS患者的时间型和干扰素注射时间与FLS评分之间的关系。
    方法:对118名MS患者进行了横断面研究,这些患者被转诊到ZanjanVali-e-Asr医院的神经内科门诊注射干扰素。邀请纳入人员完成早晚问卷(MEQ)评估患者的时间型。从患者记录中提取以下数据:年龄,性别,干扰素治疗的持续时间,服用干扰素的类型,干扰素注射时间(早/晚),FLS得分,MS亚型,和止痛药的使用。所有发现的数据均导入并在SPSSver.26中进行统计分析。
    结果:根据患者记录,114例(96.6%)患者经历过不同严重程度的干扰素后注射FLS。统计分析显示患者的时间型和FLS评分之间没有显著关系。然而,夜间注射患者的FLS评分明显较高.
    结论:干扰素注射时间与FLS评分显著相关,晚上注射后FLS评分较高。然而,FLS评分与患者的时间型无显著关系.建议需要进行使用实验室测试(例如褪黑激素测量)评估昼夜节律的进一步研究,以研究昼夜节律与干扰素注射后FLS的关联。
    BACKGROUND: Although Interferon-beta (IFNβ) has long been approved as a disease-modifying therapy (DMT) for Multiple sclerosis (MS), flu-like syndrome (FLS) persists as a common adverse effect of interferon therapy. Given the importance of circadian rhythm in regulating physiological processes, we aimed to assess the relationship between patient\'s chronotype and time of interferon injection with FLS score in MS patients receiving IFNβ.
    METHODS: A cross-sectional study was conducted on 118 MS patients who were referred to the clinic of neurology of Zanjan Vali-e-Asr Hospital for interferon injection. The included were invited to complete a morningness-eveningness questionnaire (MEQ) assessing patients\' chronotype. The following data were extracted from patients\' record: age, gender, duration of interferon treatment, type of interferon taken, time of interferon injection (morning/evening), FLS score, MS subtype, and usage of pain killers. All data found were imported and statistically analyzed in SPSS ver.26.
    RESULTS: According to the patients\' record, 114 (96.6%) patients had experienced post-interferon injection FLS with different severities. Statistical analysis revealed no significant relationship between the patient\'s chronotype and FLS score. Nevertheless, the FLS score was significantly higher in those who had evening injections.
    CONCLUSIONS: Time of interferon injection was significantly associated with FLS score, with higher FLS score following evening injection. However, no significant relationship was found between the FLS score and the patient\'s chronotype. It is recommended that further studies assessing circadian rhythm using laboratory tests such as melatonin measurement need to be undertaken to investigate the association of circadian rhythm with post-interferon injection FLS.

    多发性硬化症(MS)是一种影响中枢神经系统的长期自身免疫性疾病,以炎症为标志,脱髓鞘,和神经变性。虽然MS的确切原因尚不清楚,最近的研究表明,环境因素,特别是饮食,可能会影响疾病的风险和进展。因此,咖啡的潜在神经保护作用,世界上最受欢迎的饮料之一,由于其丰富的生物活性化合物含量而引起了人们的极大关注。本章探讨了咖啡消费对多发性硬化症患者的影响,强调像咖啡因这样的咖啡化合物,多酚,二萜可以减轻炎症和氧化应激,同时增强神经功能。它突出了咖啡因在调节腺苷受体方面的作用,特别是A1R和A2AR,在MS的神经炎症和神经保护中起重要作用。小胶质细胞的双重作用,促进炎症的同时也有助于神经保护,还强调了咖啡因的影响。此外,A2AR作为MS治疗靶点的潜力和咖啡的非A2AR依赖性神经保护益处。在本章中,我们建议饮用咖啡对MS患者没有有害影响,并且在更大程度上对公共卫生没有影响。并告知未来的研究方向和临床实践,最终改善与MS一起生活的个人的结果。
    Multiple Sclerosis (MS) is a long-term autoimmune disorder affecting the central nervous system, marked by inflammation, demyelination, and neurodegeneration. While the exact cause of MS remains unknown, recent research indicates that environmental factors, particularly diet, may influence the disease\'s risk and progression. As a result, the potential neuroprotective effects of coffee, one of the most popular beverages worldwide, have garnered significant attention due to its rich content of bioactive compounds. This chapter explores the impact of coffee consumption on patients with Multiple Sclerosis, highlighting how coffee compounds like caffeine, polyphenols, and diterpenes can reduce inflammation and oxidative stress while enhancing neural function. It highlights caffeine\'s effect in regulating adenosine receptors, specifically A1R and A2AR, which play important roles in neuroinflammation and neuroprotection in MS. The dual role of microglial cells, which promote inflammation while also aiding neuroprotection, is also highlighted concerning caffeine\'s effects. Furthermore, the potential of A2AR as a therapeutic target in MS and the non-A2AR-dependent neuroprotective benefits of coffee. In this chapter we suggest that the consumption of coffee has no harmful effect on an MS patient and to a larger extent on public health, and informs future research directions and clinical practice, ultimately improving outcomes for individuals living with MS.

    多发性硬化症(MS)是中枢神经系统(CNS)的衰弱折磨,涉及神经元轴突的脱髓鞘和神经变性,导致残疾,在疾病的进行性形式中变得更加明显。MS中神经变性的参与强调了对有效的神经保护方法的需要,需要鉴定新的治疗靶标。在这里,我们利用多种电感耦合等离子体质谱方法,将整合的元素分析工作流程应用于受MS影响的人脊髓组织.这些分析揭示了原子铜的变化是疾病的一个值得注意的方面。互补基因表达和生化分析表明,铜水平的变化与铜处理基因的表达和铜酶的下游功能的改变相吻合。在以轴索脱髓鞘为特征的疾病急性期,实验性自身免疫性脑脊髓炎(EAE)小鼠模型中大量复制了人类MS脊髓中观察到的铜相关问题,病变形成,和运动神经元丢失。用中枢神经系统渗透铜调节化合物CuII(atsm)治疗EAE小鼠导致铜酶功能恢复,改善髓鞘形成和病变体积,和神经保护。这些发现支持靶向铜扰动作为MS的治疗策略,其中CuII(atsm)显示出最初的希望。
    Multiple sclerosis (MS) is a debilitating affliction of the central nervous system (CNS) that involves demyelination of neuronal axons and neurodegeneration resulting in disability that becomes more pronounced in progressive forms of the disease. The involvement of neurodegeneration in MS underscores the need for effective neuroprotective approaches necessitating identification of new therapeutic targets. Herein, we applied an integrated elemental analysis workflow to human MS-affected spinal cord tissue utilising multiple inductively coupled plasma-mass spectrometry methodologies. These analyses revealed shifts in atomic copper as a notable aspect of disease. Complementary gene expression and biochemical analyses demonstrated that changes in copper levels coincided with altered expression of copper handling genes and downstream functionality of cuproenzymes. Copper-related problems observed in the human MS spinal cord were largely reproduced in the experimental autoimmune encephalomyelitis (EAE) mouse model during the acute phase of disease characterised by axonal demyelination, lesion formation, and motor neuron loss. Treatment of EAE mice with the CNS-permeant copper modulating compound CuII(atsm) resulted in recovery of cuproenzyme function, improved myelination and lesion volume, and neuroprotection. These findings support targeting copper perturbations as a therapeutic strategy for MS with CuII(atsm) showing initial promise.

    多发性硬化(MS)是一种严重影响中枢神经系统(CNS)的衰弱性疾病。除了神经症状,它的特征还在于神经精神合并症,如焦虑和抑郁。磷酸二酯酶-5抑制剂(PDE5Is)如西地那非和他达拉非已被证明具有抗抑郁样作用,但是支撑这种效应的机制还没有完全描述。为了解决这个问题,我们使用MS的EAE模型,行为测试,免疫荧光,免疫组织化学,westernblot,和16SrRNA测序。这里,我们表明,实验性自身免疫性脑脊髓炎(EAE)小鼠的抑郁样行为是由于神经炎症,突触可塑性降低,谷氨酸能神经传递功能障碍,糖皮质激素受体(GR)耐药,血脑屏障(BBB)通透性增加,免疫细胞浸润到中枢神经系统,以及炎症,肠道通透性增加,和远端结肠的免疫细胞浸润。此外,16SrRNA测序显示,EAE小鼠的行为功能障碍与肠道菌群的变化有关,例如Firmicutes和酵母菌的丰度增加和变形杆菌的减少,副杆菌属,和Desulfovibrio.此外,我们检测到Erypelotrichaceae和Desulfovibrionaceae的丰度增加,而约氏乳杆菌的丰度减少。令人惊讶的是,我们发现他达拉非可能通过针对上述所有疾病方面发挥抗抑郁样作用.总之,我们的工作表明,EAE中的焦虑和抑郁样行为与大量神经免疫和肠道微生物群介导的机制相关,他达拉非可能通过靶向这些机制发挥抗抑郁样作用.利用他达拉非这些作用机制的知识对于为抑郁症患者的未来临床试验铺平道路很重要。
    Multiple Sclerosis (MS) is a debilitating disease that severely affects the central nervous system (CNS). Apart from neurological symptoms, it is also characterized by neuropsychiatric comorbidities, such as anxiety and depression. Phosphodiesterase-5 inhibitors (PDE5Is) such as Sildenafil and Tadalafil have been shown to possess antidepressant-like effects, but the mechanisms underpinning such effects are not fully characterized. To address this question, we used the EAE model of MS, behavioral tests, immunofluorescence, immunohistochemistry, western blot, and 16 S rRNA sequencing. Here, we showed that depressive-like behavior in Experimental Autoimmune Encephalomyelitis (EAE) mice is due to neuroinflammation, reduced synaptic plasticity, dysfunction in glutamatergic neurotransmission, glucocorticoid receptor (GR) resistance, increased blood-brain barrier (BBB) permeability, and immune cell infiltration to the CNS, as well as inflammation, increased intestinal permeability, and immune cell infiltration in the distal colon. Furthermore, 16 S rRNA sequencing revealed that behavioral dysfunction in EAE mice is associated with changes in the gut microbiota, such as an increased abundance of Firmicutes and Saccharibacteria and a reduction in Proteobacteria, Parabacteroides, and Desulfovibrio. Moreover, we detected an increased abundance of Erysipelotrichaceae and Desulfovibrionaceae and a reduced abundance of Lactobacillus johnsonii. Surprisingly, we showed that Tadalafil likely exerts antidepressant-like effects by targeting all aforementioned disease aspects. In conclusion, our work demonstrated that anxiety- and depressive-like behavior in EAE is associated with a plethora of neuroimmune and gut microbiota-mediated mechanisms and that Tadalafil exerts antidepressant-like effects probably by targeting these mechanisms. Harnessing the knowledge of these mechanisms of action of Tadalafil is important to pave the way for future clinical trials with depressed patients.

    中枢神经系统(CNS)与嗜神经病毒感染诱导神经炎症和免疫反应,这与神经炎症和神经退行性疾病的发展有关,包括多发性硬化症(MS)。先天和适应性免疫反应的激活,涉及小胶质细胞,巨噬细胞,T和B细胞,虽然需要在中枢神经系统内有效控制病毒,也与神经病理学有关。在病理事件下,如中枢神经系统病毒感染,小胶质细胞/巨噬细胞发生反应,导致免疫细胞从外围渗入大脑,破坏中枢神经系统稳态并有助于疾病的发病机理。Theiler鼠脑脊髓炎病毒(TMEV)诱导的脱髓鞘疾病(TMEV-IDD),作为MS的小鼠模型该小鼠模型为我们对感染后MS的病理生理学的理解做出了重大贡献。小胶质细胞/巨噬细胞可以被激活成两种不同的状态,TMEV感染期间的经典激活状态(M1状态)和替代激活状态(M2状态)。M1具有启动炎症反应并分泌促炎细胞因子的能力,和M2样的小胶质细胞/巨噬细胞是抗炎的,其特征在于分泌抗炎细胞因子。本文旨在讨论小胶质细胞/巨噬细胞M1/M2样极化在TMEV感染中的作用。并探讨平衡小胶质细胞/巨噬细胞M1/M2样极化对MS的潜在治疗作用。
    The infection of the central nervous system (CNS) with neurotropic viruses induces neuroinflammation and an immune response, which is associated with the development of neuroinflammatory and neurodegenerative diseases, including multiple sclerosis (MS). The activation of both innate and adaptive immune responses, involving microglia, macrophages, and T and B cells, while required for efficient viral control within the CNS, is also associated with neuropathology. Under pathological events, such as CNS viral infection, microglia/macrophage undergo a reactive response, leading to the infiltration of immune cells from the periphery into the brain, disrupting CNS homeostasis and contributing to the pathogenesis of disease. The Theiler\'s murine encephalomyelitis virus (TMEV)-induced demyelination disease (TMEV-IDD), which serves as a mouse model of MS. This murine model made significant contributions to our understanding of the pathophysiology of MS following subsequent to infection. Microglia/macrophages could be activated into two different states, classic activated state (M1 state) and alternative activated state (M2 state) during TMEV infection. M1 possesses the capacity to initiate inflammatory response and secretes pro-inflammatory cytokines, and M2-liked microglia/macrophages are anti-inflammatory characterized by the secretion of anti-inflammatory cytokines. This review aims to discuss the roles of microglia/macrophages M1/M2-liked polarization during TMEV infection, and explore the potential therapeutic effect of balancing M1/M2-liked polarization of microglia/macrophages on MS.

    多发性硬化症(MS)是一种慢性炎性疾病,其特征是对中枢神经系统的神经退行性影响。MS的复杂性及其给患者带来的重大挑战使探索有效治疗成为研究的关键领域。在调查的各种机制中,炎症在MS进展中的作用尤其令人感兴趣。体内的炎症反应受到各种细胞机制的调节,其中一个涉及核苷酸结合寡聚化结构域(NOD)-,富含亮氨酸的重复序列(LRR)-,和含pyrin结构域(PYD)的蛋白3(NLRP3)。NLRP3充当细胞内的传感器,在控制炎症反应中起关键作用。它的激活是导致NLRP3炎性体复合物组装的关键步骤,对MS等炎症性疾病具有深远意义的过程。NLRP3炎性体的激活与随后的胱天蛋白酶1和gasderminD(GsdmD)的激活密切相关,信号通路是炎症过程的核心。GsdmD,Gasdermin蛋白家族的重要成员,特别值得注意的是它在焦转细胞死亡中的作用,一种与细胞凋亡不同的程序性细胞死亡形式,其特征在于其炎症性质。该途径的激活通过加重神经系统内的炎症反应而显著地促进MS的病理。鉴于MS中不受调节的炎症的有害影响,针对这些炎症过程的治疗方法为缓解患者所经历的症状提供了有希望的途径。这篇综述深入研究了退化途径的复杂性,强调NLRP3炎性体的形成如何诱导此类途径以及治疗药物的潜在干预点。通过抑制这些途径中的关键步骤,有可能减轻炎症反应,从而为患有MS的人提供救济。了解这些机制不仅为MS的病理生理学提供了启示,而且为开发旨在通过调节机体炎症反应来控制疾病进展的新型治疗策略铺平了道路。
    Multiple sclerosis (MS) stands as a chronic inflammatory disease characterized by its neurodegenerative impacts on the central nervous system. The complexity of MS and the significant challenges it poses to patients have made the exploration of effective treatments a crucial area of research. Among the various mechanisms under investigation, the role of inflammation in MS progression is of particular interest. Inflammatory responses within the body are regulated by various cellular mechanisms, one of which involves the nucleotide-binding oligomerization domain (NOD)-, leucine-rich repeat (LRR)-, and pyrin domains (PYD)-containing protein 3 (NLRP3). NLRP3 acts as a sensor within cells, playing a pivotal role in controlling the inflammatory response. Its activation is a critical step leading to the assembly of the NLRP3 inflammasome complex, a process that has profound implications for inflammatory diseases like MS. The NLRP3 inflammasome\'s activation is intricately linked to the subsequent activation of caspase 1 and gasdermin D (GsdmD), signaling pathways that are central to the inflammatory process. GsdmD, a prominent member of the Gasdermin protein family, is particularly noteworthy for its role in pyroptotic cell death, a form of programmed cell death that is distinct from apoptosis and is characterized by its inflammatory nature. This pathway\'s activation contributes significantly to the pathology of MS by exacerbating inflammatory responses within the nervous system. Given the detrimental effects of unregulated inflammation in MS, therapeutics targeting these inflammatory processes offer a promising avenue for alleviating the symptoms experienced by patients. This review delves into the intricacies of the pyroptotic pathways, highlighting how the formation of the NLRP3 inflammasome induces such pathways and the potential intervention points for therapeutic agents. By inhibiting key steps within these pathways, it is possible to mitigate the inflammatory response, thereby offering relief to those suffering from MS. Understanding these mechanisms not only sheds light on the pathophysiology of MS but also paves the way for the development of novel therapeutic strategies aimed at controlling the disease\'s progression through the modulation of the body\'s inflammatory response.

    背景:多发性硬化(MS)是一种慢性自身免疫性疾病,中枢神经系统的炎症性神经系统疾病。利鲁唑和富马酸二甲酯(DMF)是FDA批准的两种治疗肌萎缩侧索硬化症(ALS)和MS的药物。利鲁唑(苯并噻唑衍生物)通过拮抗N-甲基-D-天冬氨酸(NMDA)受体来抑制神经末梢的谷氨酸释放,和DMF上调抗氧化途径。
    目的:在此,使用分子杂交策略,我们通过一些常见的连续合成途径合成了利鲁唑和DMF的一些新的混合结构,以评估其在MS治疗中的髓鞘再生的潜在活性。
    方法:分子对接实验评估了所提出的结构与NMDA活性位点的结合亲和力。基于众所周知的化学合成程序合成和纯化设计的结构。之后,在C57Bl/6Cuprizone诱导的脱髓鞘MS模型中对其活性进行体内评估。
    结论:基于对接研究,所提出的衍生物被认为是足够有效的(与依芬地尔(-6.98)和利鲁唑(-4.42)相比,所有衍生物的ΔG结合为-7.2至-7.52)。使用光谱法确认所需衍生物的正确结构。基于体内研究,D4和D6衍生物表现出最好的药理学结果,尽管与对照相比,只有D6显示出统计学上的显着差异。此外,对于D4和D6衍生物,髓鞘染色证实call体变性减少。因此,D4和D6衍生物是开发具有针对MS病症的治疗价值的新型NMDA拮抗剂的有希望的候选物。
    BACKGROUND: Multiple Sclerosis (MS) is a chronic autoimmune, inflammatory neurological disease of the CNS. Riluzole and dimethyl fumarate (DMF) are two FDA-approved drugs to treat amyotrophic lateral sclerosis (ALS) and MS. Riluzole (a benzothiazole derivative) inhibits glutamate release from nerve terminals by antagonizing the N-Methyl-D-Aspartate (NMDA) receptor, and DMF upregulates anti-oxidative pathways.
    OBJECTIVE: Herein, using molecular hybridization strategy, we synthesized some new hybrid structures of Riluzole and DMF through some common successive synthetic pathways for evaluating their potential activity for remyelination in MS treatment.
    METHODS: Molecular docking experiments assessed the binding affinity of proposed structures to the NMDA active site. The designed structures were synthesized and purified based on well-known chemical synthesis procedures. Afterward, in vivo evaluation for their activity was done in the C57Bl/6 Cuprizone-induced demyelination MS model.
    CONCLUSIONS: The proposed derivatives were recognized to be potent enough based on docking studies (ΔGbind of all derivatives were -7.2 to -7.52 compare to the Ifenprodil (-6.98) and Riluzole (-4.42)). The correct structures of desired derivatives were confirmed using spectroscopic methods. Based on in vivo studies, D4 and D6 derivatives exhibited the best pharmacological results, although only D6 showed a statistically significant difference compared to the control. Also, for D4 and D6 derivatives, myelin staining confirmed reduced degeneration in the corpus callosum. Consequently, D4 and D6 derivatives are promising candidates for developing new NMDA antagonists with therapeutic value against MS disorders.

    利妥昔单抗已在冰岛用于治疗MS患者十多年。然而,利妥昔单抗对白细胞群的长期影响尚未阐明.通过回顾性分析2012年至2023年在冰岛国立大学医院接受利妥昔单抗治疗的349例患者的流式细胞术数据,我们评估了利妥昔单抗的长期疗效以及疗效是否为剂量依赖性(1000mgvs500mg).当与1000mg相比时,在用500mg作为初始剂量的利妥昔单抗治疗的患者中,B细胞耗竭的功效没有检测到差异。长期使用利妥昔单抗导致接受3-8剂量利妥昔单抗(1.5-8年治疗)的患者T细胞计数增加(p=0.0015)。增加发生在CD4+(p=0.0028)和CD8+T细胞(p=0.0015)中,并导致CD4/CD8比率降低(p=0.004)。最显着的差异在于重塑näive和效应CD8T细胞之间的平衡。利妥昔单抗长期治疗的临床意义及其对T细胞池的影响需要进一步探讨。由于两组患者之间没有检测到B细胞耗竭的差异,1000mg作为初始剂量可能过量,提示个性化给药方案可能具有治疗和经济优势.
    Rituximab has been used to treat MS patients in Iceland for over a decade. However, long-term effect of rituximab on leukocyte populations has not yet been elucidated. By retrospective analysis of flow cytometric data from 349 patients visiting the neurological ward at The National University Hospital of Iceland from 2012 to 2023 for rituximab treatment, the long-term effect of rituximab and whether the effect was dose dependent (1000mg vs 500mg) was evaluated. No difference was detected in efficacy of B cell depletion in patients treated with 500mg as an initial dose of rituximab when compared to 1000mg. Long-term use of rituximab led to an increase in T cell count (p=0,0015) in patients receiving 3-8 doses of rituximab (1.5-8 years of treatment). The increase occurred in both CD4+ (p=0,0028) and CD8+ T cells (p=0,0015) and led to a decrease in the CD4/CD8 ratio (p=0,004). The most notable difference lies in reshaping the balance between näive and effector CD8+ T cells. The clinical implications of long-term treatment with rituximab and its effect on the T cell pool needs to be explored further. Since no difference in B cell depletion was detected between the two patient groups, 1000mg as an initial dose might be excessive, suggesting a personalized dosing regimen might have therapeutic and financial advantages.

    (1)背景:多发性硬化症(MS)是一种慢性,复杂,脱髓鞘疾病与微量元素水平的改变密切相关。尽管关于微量元素在MS中的作用的第一个研究发表在20世纪70年代,五十年来,人们一直不知道微量元素是否可以成为这种异质性神经系统疾病的一部分。(2)材料和方法:为了朝着潜在的解决方案前进,我们进行了系统评价和荟萃分析,以阐明神经重要的必需微量元素的循环水平是否存在差异(锌,Fe,Co,Cu,Mn,和Se)在MS病例和对照之间。(3)结果:与对照组相比,该研究揭示了受MS影响的个体中显著较低的血清/血浆Zn和Fe水平和较高的Cu水平。同时,MS病例和对照组之间的血清/血浆Co水平没有发现显着差异,Mn,或者Se。因此,在MS患者的补充/营养策略中应考虑铁和锌的损失.另一方面,由于高血清Cu水平表明MS患者的血液负担,铜应该从矿物质补充策略中排除。此外,所有三种微量元素(Fe,Zn,和铜)应从病因学的角度考虑,and,最重要的是,应监测其在MS患者血流中的水平.(4)结论:本研究强调了在MS管理中个性化和针对性策略的途径。
    (1) Background: Multiple sclerosis (MS) is a chronic, complex, and demyelinating disease closely associated with altered levels of trace elements. Although the first studies into the role of trace elements in MS were published in the 1970s, for five decades it has remained unknown whether trace elements can be part of this heterogeneous neurological disease. (2) Materials and methods: To drive toward at a potential solution, we conducted a systematic review and meta-analysis to elucidate whether there were differences in circulating levels of neurologically important essential trace elements (Zn, Fe, Co, Cu, Mn, and Se) between MS cases and controls. (3) Results: This study revealed significantly lower serum/plasma Zn and Fe levels and higher Cu levels in MS-affected individuals compared to controls. At the same time, no significant differences were found between the MS cases and controls regarding their serum/plasma levels of Co, Mn, or Se. Thus, the loss of Fe and Zn should be considered in supplementation/nutrition strategies for MS patients. On the other hand, since high serum Cu levels indicate a burden on the bloodstreams of MS patients, Cu should be excluded from mineral supplement strategies. Furthermore, all three trace elements (Fe, Zn, and Cu) should be considered from an etiological point of view, and, most importantly, their levels in the bloodstreams of MS patients should be monitored. (4) Conclusions: This study highlights the way for personalized and targeted strategies in the management of MS.
