Abstract
Since the 1980s it is known that immune responses to the Epstein-Barr virus (EBV) are elevated in multiple sclerosis (MS) patients. Recent seroepidemiologial data have shown that this alteration after primary EBV infection identifies individuals with a more than 30-fold increased risk to develop MS. The mechanisms by which EBV infection might erode tolerance for the central nervous system (CNS) in these individuals, years prior to clinical MS onset, remain unclear. In this review I will discuss altered frequencies of EBV life cycle stages and their tissue distribution, EBV with CNS autoantigen cross-reactive immune responses and loss of immune control for autoreactive B and T cells as possible mechanisms. This discussion is intended to stimulate future studies into these mechanisms with the aim to identify candidates for interventions that might correct EBV specific immune control and/or resulting cross-reactivities with CNS autoantigens in MS patients and thereby ameliorate disease activity.

Abstract
Multiple sclerosis remains one of the most common causes of neurological disability in the young adult population (aged 18-40 years). Novel pathophysiological findings underline the importance of the interaction between genetics and environment. Improvements in diagnostic criteria, harmonised guidelines for MRI, and globalised treatment recommendations have led to more accurate diagnosis and an earlier start of effective immunomodulatory treatment than previously. Understanding and capturing the long prodromal multiple sclerosis period would further improve diagnostic abilities and thus treatment initiation, eventually improving long-term disease outcomes. The large portfolio of currently available medications paved the way for personalised therapeutic strategies that will balance safety and effectiveness. Incorporation of cognitive interventions, lifestyle recommendations, and management of non-neurological comorbidities could further improve quality of life and outcomes. Future challenges include the development of medications that successfully target the neurodegenerative aspect of the disease and creation of sensitive imaging and fluid biomarkers that can effectively predict and monitor disease changes.

Abstract
Our registry-based cross-sectional study covered 27,508 PwMS in Tehran with a point incidence rate and prevalence of 7.87 and 194.62 per 100,000 in 2021, respectively. We found that the incidence and prevalence of MS in Tehran are still on an upward trend which requires general attention and measures to overcome. The proportion of men with a family history of MS was significantly higher. Whilst IMSS deals with economic difficulties, it continues to collect new PwMS to reach regional-level coverage in Tehran for better MS care services.

Abstract
This research aimed to assess gray matter (GM), white matter (WM), lesions of multiple sclerosis (MS) and the therapeutic effect using diffusion kurtosis imaging (DKI). From January 2018 to October 2019, 78 subjects (48 of MS and 30 of health) perform routine MR scan and DKI of cervical spinal cord. The MS patients were divided into 2 groups according to the presence or absence of T2 hyperintensity. DKI-metrics were measured in the lesions, normal-appearing GM and WM. Significant differences were detected in DKI metrics between MS and healthy (P < .05) and between patients with cervical spinal cord T2-hyperintense and without T2-hyperintense (P < .001). Compared to healthy, GM-mean kurtosis (MK), GM-radial kurtosis, and WM-fractional anisotropy, WM-axial diffusion were statistically reduced in patients without T2-hyperintense (P < .05). Significant differences were observed in DKI metrics between patients with T2-hyperintense after therapy (P < .05), as well as GM-MK and WM-fractional anisotropy, WM-axial diffusion in patients without T2-hyperintense (P < .05); Expanded Disability Status Scale was correlated with MK values, as well as Expanded Disability Status Scale scores and MK values after therapy. Our results indicate that DKI-metrics can detect and quantitatively evaluate the changes in cervical spinal cord micropathological structure.

Prognostic significance of neurofilament light in Fingolimod therapy for Multiple Sclerosis: A systemic review and meta-analysis based on randomized control trials. Mult Scler Relat Disord 2023; 69:104416. [PMID: 36495843 DOI: 10.1016/j.msard.2022.104416] [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: 10/10/2022] [Revised: 11/11/2022] [Accepted: 11/14/2022] [Indexed: 11/18/2022]
Abstract
OBJECTIVE This research was conducted to assess Neurofilament light chain (NfL) as prognostic factor for Multiple Sclerosis and effect of Fingolimod on plasma levels of NfL. MATERIALS AND METHODS A systemic search was conducted from electronic databases (PubMed/Medline, Cochrane Library, and Google Scholar) from inception to 7th September 2022. All statistical analyses were conducted in Review Manager 5.4.1. Studies meeting inclusion criteria were selected. Only those studies that involved Multiple sclerosis patients in which plasma levels of NfL was provided and Fingolimod was used in the treatment group. Fixed-effect model was used to pool the studies to assess NfL as prognostic factor, which was reported in the Hazards ratio (HR) and their corresponding 95% confidence interval (CI). Moreover, effect of Fingolimod on NfL levels was analysed qualitatively. RESULTS Five Randomized Controlled Trials were used in the study. Four studies were used in quantitative analysis which showed increased NfL was related to significant increase in cognitive disability worsening (HR= 1.66 [1.35, 2.05]; p< 0.00001; I2= 0%). The qualitative analysis method was employed to evaluate the factors correlating with increased NfL levels in Multiple Sclerosis patients. Five studies evaluated that there was significant decrease in NfL levels when Fingolimod was used as compared to placebo. 4 studies were included to correlated NfL levels with clinical and MRI parameters and association was found between increasing NfL levels and relapses, active/new T2 lesions and percentage of brain volume change. CONCLUSION The results of our meta-analysis and systematic review demonstrated statistically significant effect of NfL as a prognostic marker with its level being decreased significantly when Fingolimod was used for treating Multiple Sclerosis.

Abstract
Background Admittedly, little is known about the epidemiological signatures of familial multiple sclerosis (FMS) in different geographical regions of Iran. Objective To determine the epidemiology and the risk of FMS incidence in several provinces of Iran with a different ethnic population including, Fars, Tehran, Isfahan (Persians), and Mazandaran (Mazanis), Kermanshah (Kurds), and Chaharmahal and Bakhtiari (Lors). Methods This cross-sectional registry-based study was performed on nationwide MS registry of Iran (NMSRI) data collected from 2018 to 2021. This system, registers baseline characteristics, clinical presentations and symptoms, diagnostic and treatments at regional and national levels. Results A total of 9200 patients including, 7003 (76.1%) female and 2197 (23.9%) male, were participated. About 19% of patients reported a family history of MS; the order from highest to lowest FMS prevalence was as follows: Fars (26.5%), Chaharmahal and Bakhtiari (21.1%), Tehran (20.5%), Isfahan (20.3%), Mazandaran (18.0%), and Kermanshah (12.5%). Of all FMS cases, 74.7% (1308 cases) were female and 25.3% (442 cases) were male. FMS occurrence was much more common in females than males (P-value = 0.001). Further, the mean age at onset was 30 years among FMS cases. A substantially higher probability of relapsing-remitting MS and secondary-progressive MS was found among FMS cases than sporadic MS (SMS) (P_value = 0.001). There was no significant difference in Expanded Disability Status Scale (EDSS) scores between FMS and SMS. The majority of FMS cases were observed among first-degree relatives, with the highest rate in siblings. There was a significant association between MS risk and positive familial history in both maternal and paternal aunt/uncle (P_value = 0.043 and P_value = 0.019, respectively). Multiple sclerosis occurrence among offspring of females was higher than males (P_value = 0.027). Conclusions In summary, our findings imply a noteworthy upward trend of FMS in Iran, even more than the global prevalence, which suggests a unique Atlas of FMS prevalence in this multi-ethnic population. Despite the highest rate of FMS within Persian and Lor ethnicities, no statistically significant difference was observed among the provinces.

Abstract
Multiple sclerosis is a complex, autoimmune-mediated disease of the central nervous system characterized by inflammatory demyelination and axonal/neuronal damage. The approval of various disease-modifying therapies and our increased understanding of disease mechanisms and evolution in recent years have significantly changed the prognosis and course of the disease. This update of the Multiple Sclerosis Therapy Consensus Group treatment recommendation focuses on the most important recommendations for disease-modifying therapies of multiple sclerosis in 2021. Our recommendations are based on current scientific evidence and apply to those medications approved in wide parts of Europe, particularly German-speaking countries (Germany, Austria, and Switzerland).

RNA Sequencing of CD4 + T Cells in Relapsing-Remitting Multiple Sclerosis Patients at Relapse: Deciphering the Involvement of Novel genes and Pathways. J Mol Neurosci 2021; 71:2628-2645. [PMID: 34286457 DOI: 10.1007/s12031-021-01878-8] [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: 06/11/2021] [Accepted: 06/18/2021] [Indexed: 10/20/2022]
Abstract
CD4+ T cells are known as a noteworthy potential modulator of inflammation in multiple sclerosis (MS). In the current study, we investigated the transcriptome profile of CD4+ T cells in patients with relapsing-remitting MS (RRMS) at the relapse phase. We performed RNA sequencing of CD4+ T cells isolated from four relapsing-remitting MS (RRMS) patients at the relapse phase and four age- and sex-matched healthy controls. The edgeR statistical method was employed to determine differentially expressed genes (DEGs). Gene set enrichment analysis was subsequently performed. Applying a physical interaction network, genes with higher degrees were selected as hub genes. A total of 1278 and 1034 genes were defined at significantly higher or lower levels, respectively, in CD4+ T cells of RRMS patients at the relapse phase as compared with healthy controls. The top up- and downregulated genes were JAML and KDM3A. The detected DEGs were remarkable on chromosomes 1 and 2, respectively. The DEGs were mainly enriched in the pathways "regulation of transcription, DNA-templated," "regulation of B cell receptor signaling pathway," "protein phosphorylation," "epidermal growth factor receptor signaling pathway," and "positive regulation of neurogenesis." Moreover, 16 KEGG pathways mostly associated with the immune system and viral infections were enriched. In the constructed physical interaction networks, UBA52 and TP53 were shown to be the most highly ranked hub genes among upregulated and downregulated genes, respectively. By applying global transcriptome profiling of CD4+ T cells, we deciphered the involvement of several novel genes and pathways in MS pathogenesis. The present results must be confirmed by in vivo and in vitro studies.

Abstract
Multiple sclerosis is a highly heterogeneous disease, and the detection of neuroaxonal damage as well as its quantification is a critical step for patients. Blood-based serum neurofilament light chain (sNfL) is currently under close investigation as an easily accessible biomarker of prognosis and treatment response in patients with multiple sclerosis. There is abundant evidence that sNfL levels reflect ongoing inflammatory-driven neuroaxonal damage (e.g. relapses or MRI disease activity) and that sNfL levels predict disease activity over the next few years. In contrast, the association of sNfL with long-term clinical outcomes or its ability to reflect slow, diffuse neurodegenerative damage in multiple sclerosis is less clear. However, early results from real-world cohorts and clinical trials using sNfL as a marker of treatment response in multiple sclerosis are encouraging. Importantly, clinical algorithms should now be developed that incorporate the routine use of sNfL to guide individualized clinical decision-making in people with multiple sclerosis, together with additional fluid biomarkers and clinical and MRI measures. Here, we propose specific clinical scenarios where implementing sNfL measures may be of utility, including, among others: initial diagnosis, first treatment choice, surveillance of subclinical disease activity and guidance of therapy selection.

Abstract
Background Iran is one of the countries with a high prevalence of multiple sclerosis (MS) and COVID-19.MS patients receiving the immunomodulatory or immunosuppressive therapy have a higher risk of infection. Due to the significance of determining the risk factors for getting COVID-19 among MS patients, the present study was designed to assess the risk of infection following the pulse steroid therapy. Methods This cross-sectional study included all MS patients that received corticosteroids in Tehran from December 2019 to August 2020 during the COVID-19 pandemic spread. The subjects’ clinical records including their sex, age, the type of MS, the type of medication, the number of days using corticosteroids, the status of prednisolone intake, and the number of days receiving prednisolone after the corticosteroid therapy were obtained. Moreover, main outcomes such as COVID-19 infection and the occurrence of death were recorded by patient’s visits and follow-up phone calls. COVID-19 infection was confirmed by physicians according to the clinical performance of RT-PCR, chest CT scan, and antibody tests. Results Totally, 133 MS cases participated in the study, and the pulse therapy was completed for 104 (78.2%) patients up to 5−7 days. 89 (66.9%) cases used the prednisolone tablet following the pulse therapy. Overall, the infection by Covid-19 was observed in 8 (6%) cases, among whom 5 (71.4%) cases received the pulse therapy for 5−7 days and 4 (57.1%) cases had a history of taking the prednisolone tablet. The age of less than 40 years (OR = 1.03; 95% CI (0.23−4.51)), male sex (OR = 0.35; 95% CI (0.03−3.34)), and the RRMS type (OR = 2.87; 95% CI (0.52−15.72)) had no effect on the risk of Covid-19 infection. In addition, there was not statistically significant difference between subjects with the short-term pulse therapy duration (3−4 days) (OR 0.68 (0.12–3.74) and those with the long-term pulse therapy duration (5−7 days). Similarly, no statistically significant difference was observed between subjects taking prednisolone (OR = 1.62 (0.34–7.61) and those not taking prednisolone. Furthermore, there was no significant association between different medication groups and the risk of Covid-19 infection (p < 0.05). No death occurred due to Covid-19 infection among the subjects. Conclusion COVID-19 infection was more common among female and younger patients as well as patients with a longer duration of the pulse therapy and prednisolone intake. There was no significant association between the pulse steroid therapy in MS patients and the risk of infection by COVID-19 in the Iranian population.

Abstract
Background: Diagnostic criteria for multiple sclerosis have evolved over time, with the most recent being the 2017 McDonald criteria. Evidence is lacking regarding the validity of the 2017 McDonald criteria among the Asian population. Therefore, this study aims to evaluate the diagnostic performance of the 2017 McDonald criteria in Chinese patients with clinically isolated syndrome (CIS). Methods: A total of 93 patients with initial findings suggestive of CIS in a tertiary hospital in China from 2012 to 2017 were included in this retrospective study. Baseline and follow-up data were reviewed. Diagnostic performance (sensitivity, specificity, accuracy), was assessed and survival analysis was performed for the 2017 and 2010 McDonald criteria respectively. Results: Among the 93 Chinese patients with CIS, 57 were female (61.3%) and the median (interquartile range) age of onset was 37 (31.3–41.8) years. The 2017 McDonald criteria displayed a higher sensitivity (75.0% versus 14.6%, p < 0.0001), lower specificity (47.1% versus 100.0%, p < 0.05) but an overall higher accuracy (67.7% versus 36.9%, p < 0.0001) when compared with the 2010 iteration. The novel criteria allow for a better detection of MS at baseline (40.8% versus 9.9%, p < 0.0001). Conclusion: The 2017 McDonald criteria had a higher sensitivity but lower specificity than the 2010 iteration. Overall it facilitated an earlier and more accurate diagnosis of multiple sclerosis in Chinese patients with CIS.

HIV-1 Tat protein attenuates the clinical course of experimental autoimmune encephalomyelitis (EAE). Int Immunopharmacol 2019; 78:105943. [PMID: 31830622 DOI: 10.1016/j.intimp.2019.105943] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2019] [Revised: 09/04/2019] [Accepted: 09/26/2019] [Indexed: 01/01/2023]
Abstract
A growing body of evidence has shown that the human immunodeficiency virus (HIV) infection is associated with a significantly decreased risk of developing multiple sclerosis (MS) in patients with acquired immunodeficiency virus (AIDS). It is thought that two mechanisms are in charge of protection against MS, which include immunosuppression induced by chronic HIV infection (depletion of CD4 + T cells) and antiretroviral medications. HIV-1 encodes several regulatory (Tat and Rev) and accessory (Vpr, Vif, Vpu, and Nef) proteins that have immunosuppressive and immunomodulatory properties. HIV-1 Tat protein is a strongly immunosuppressive agent and can cross the blood-brain barrier (BBB). In this study, we examined the effect of HIV-1 Tat, which is classified into clade B and C, on inflammation, gliosis, apoptosis, and behavioral function in a murine model of MS called experimental autoimmune encephalomyelitis (EAE). For this aim, mice were immunized with myelin oligodendrocyte glycoprotein 35-55 (MOG35-55), followed by pertussis toxin to induce paralysis in EAE mice. After the induction of EAE in mice, the animals intraperitoneally received serial doses of HIV-1 Tat clade B and C (5, 10, and 20 µg/kg body weight) when the early clinical manifestations of EAE were initiated. The results showed that the administration of both clades of the Tat protein led to a marked decrease in the clinical score of EAE mice, as well as improvement in motor-neuron functions. In line with this, Tat considerably reduced the number of apoptotic cells in the sacral region of the spinal cord through the upregulation expression of the Bcl-2 protein. Besides, proinflammatory cytokines such as, IFN-γ, TNF-α, IL-6, and IL-17 were significantly diminished in the serum and spinal cord of EAE mice receiving HIV-1 Tat clade B and C. Conversely, anti-inflammatory cytokines, including IL-10 and IL-4 were elevated in the serum and spinal cord of EAE mice receiving HIV Tat clade B and C when compared with the control group. The immunohistochemical analysis indicated that HIV-1 Tat clade B and C mitigated microgliosis and astrogliosis. The flow cytometry analysis demonstrated that the number of Th1 and Th17cells was significantly decreased in response to TAT administration while the frequency of Th2 cells was markedly increased in the peripheral blood of mice with EAE without influencing the number of T regulatory cells (CD4 + CD25 + forkhead box protein 3 + ). It seems that HIV-1 Tat could be a bona fide therapeutic protein for the alleviation of MS since it has beneficial roles in the suppression of neuroinflammation in MS pathology.

Cognitive performance and cognitive workload in multiple sclerosis: Two different constructs of cognitive functioning? Mult Scler Relat Disord 2019; 38:101505. [PMID: 31743847 DOI: 10.1016/j.msard.2019.101505] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2019] [Revised: 09/24/2019] [Accepted: 11/04/2019] [Indexed: 12/26/2022]
Abstract
BACKGROUND Cognitive impairment in individuals with Multiple Sclerosis (iwMS) is traditionally diagnosed using performance measures on cognitive tests. Yet, performance on cognitive tests does not convey the amount of mental effort or cognitive workload it takes to complete the task. The main aim was to evaluate whether cognitive performance and cognitive workload are two different constructs of cognitive functioning in iwMS. METHODS IwMS were categorized into cognitive impairments (iwMS+, n = 10) and no cognitive impairments (iwMS-, n = 12) using their performance on Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS). Their scores on BICAMS, Stroop, and trail making tests were compared to age- and education-matched controls (n = 22). Cognitive workload was assessed using the self-reported NASA Task Load Index and the Index of Cognitive Activity, derived from pupillary response. RESULTS IwMS+ performed worse on most cognitive tests compared to iwMS- and controls. However, iwMS+ did not report or exhibit greater cognitive workload compared to the other groups. Potential confounding variables, such as sex, use of antidepressants, and symptoms of depression, fatigue, and dysautonomia did not influence the lack of correlation between cognitive performance and cognitive workload in all three groups. CONCLUSION Cognitive performance and cognitive workload seem to measure different cognitive constructs of cognitive functioning in MS. Our results suggest that iwMS+ do not show effective allocation of cognitive resources to compensate for deteriorated performance in cognitive tests.
