ABSTRACT
BACKGROUND: Neuromyelitis optica spectrum disorder (NMOSD) can be categorised into aquaporin-4 antibody (AQP4-IgG) NMOSD or seronegative NMOSD. While our knowledge of AQP4-IgG NMOSD has evolved significantly in the past decade, seronegative NMOSD remains less understood. This study aimed to evaluate the predictors of relapses and treatment responses in AQP4-IgG NMOSD and seronegative NMOSD. METHODS: This was a multicentre, international, retrospective cohort study using the MSBase registry. Recurrent relapse risk was assessed using an Andersen-Gill model and risk of first relapse was evaluated using a Cox proportional hazards model. Covariates that putatively influence relapse risk included demographic factors, clinical characteristics and immunosuppressive therapies; the latter was assessed as a time-varying covariate. RESULTS: A total of 398 patients (246 AQP4-IgG NMOSD and 152 seronegative NMOSD) were included. The AQP4-IgG NMOSD and seronegative NMOSD patients did not significantly differ by age at disease onset, ethnicity or annualised relapse rate. Both low-efficacy and high-efficacy immunosuppressive therapies were associated with significant reductions in recurrent relapse risk, with notably greater protection conferred by high-efficacy therapies in both AQP4-IgG NMOSD (HR 0.27, 95% CI 0.15 to 0.49, p<0.001) and seronegative NMOSD (HR 0.21, 95% CI 0.08 to 0.51, p<0.001). Longer disease duration (HR 0.97, 95% CI 0.95 to 0.99, p<0.001) and male sex (HR 0.52, 95% CI 0.34 to 0.84, p=0.007) were additional protective variables in reducing the recurrent relapse risk for the AQP4-IgG NMOSD group. CONCLUSION: Although further studies are needed to improve our understanding of seronegative NMOSD, our findings underscore the importance of aggressive treatment with high-efficacy immunotherapies in both NMOSD subtypes, regardless of serostatus.
ABSTRACT
Cerebellar ataxias are a wide heterogeneous group of disorders that may present with fine motor deficits as well as gait and balance disturbances that have a significant influence on everyday activities. To review the ocular movements in cerebellar ataxias in order to improve the clinical knowledge of cerebellar ataxias and related subtypes. English papers published from January 1990 to May 2022 were selected by searching PubMed services. The main search keywords were ocular motor, oculomotor, eye movement, eye motility, and ocular motility, along with each ataxia subtype. The eligible papers were analyzed for clinical presentation, involved mutations, the underlying pathology, and ocular movement alterations. Forty-three subtypes of spinocerebellar ataxias and a number of autosomal dominant and autosomal recessive ataxias were discussed in terms of pathology, clinical manifestations, involved mutations, and with a focus on the ocular abnormalities. A flowchart has been made using ocular movement manifestations to differentiate different ataxia subtypes. And underlying pathology of each subtype is reviewed in form of illustrated models to reach a better understanding of each disorder.

BACKGROUND: Several etiologies are responsible for presentation of a twitching tongue in clinical practice. Some of these etiologies cause an isolated hyperkinetic tongue muscle, and some others cause it along with other signs and symptoms. OBJECTIVES: The present paper aims to review the causes, pathology, and presentations reported with twitchy tongue. An anatomical basis of the etiologies responsible for presentation of a twitchy tongue and hyperkinetic movement disorders of this muscle is pursued. METHOD: The reporting of this systematic review was guided by the standards of the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) Statement. All of the research papers conducted with keywords described in the method section between 2000 and 2022 were used, and review articles and articles without any human subject and without any described hyperkinetic movement disorders of the tongue were excluded. RESULTS: All of the etiologies responsible for hyperkinetic movement disorders of tongue were listed in the basis of their anatomical site of effect; cortical region, basal ganglia, cerebellum, brain stem, nucleus and nerve, and neuromuscular junction. One last remained part is the "not classified" section, which contains the etiologies with no particular anatomical origin. CONCLUSION: There are a variety of responsible etiologies for presentation of a twitchy tongue, and in the matter of a complaint of hyperkinetic tongue presentation, physicians should consider anatomical, functional, and psychological etiologies and other signs and symptoms must be participated in the diagnosis process to achieve a proper medical decision.

BACKGROUND: Diagnosis of Parkinson's disease (PD) is associated with a vast number of challenges. This study aimed to assess the overlap of PD patients' transcriptomes in the substantia nigra (SN) with peripheral blood mononuclear cells (PBMCs) to discover potential biomarkers for diagnosis. METHODS: GEO data were used to select genes with significant changes in expression level in the SN region and eligible studies. Also, transcriptome data related to blood of PD patients with other neurodegenerative diseases (ND) was considered. Differential expression genes between PD and control were evaluated in the SN and blood, and RT-qPCR was applied to validate the findings. RESULTS: At the expression level, no significant similarity in long non-coding RNA was found between the patients' SN and blood. While in silico results revealed 16 common mRNAs in SN and blood with significant expression levels. Among all overexpressed mRNAs, HSPA1A/B expression level had the highest expression difference between control and PD samples. Moreover, DGKH had the highest score of down-regulated genes in both blood and SN. The NOTCH pathway had the highest score pathway among up-regulated pathways, and the expression levels of NOTCH2, H4C8, and H2BC21 associated with this pathway had the most ability to separate the control and PD populations. Furthermore, RT-qPCR results revealed that HSPA1A/B, NOTCH2, and H4C8 were overexpressed in PD PBMCs, while DGKH expression levels were lower compared to controls. CONCLUSION: Our findings indicate that expression levels of HSPA1A/B, DGKH, and NOTCH2 could be applied as candidate biomarkers to diagnose PD patients in the SN region and PBMCs.

INTRODUCTION: Dysphagia as a consequence of multiple sclerosis (MS) puts individuals at higher risk of dehydration, malnutrition, and aspiration pneumonia. This study intended to investigate the effects of a combined program of neuromuscular electrical stimulation (NMES) and conventional swallowing therapy to improve swallow safety and efficiency, oral intake, and physical, emotional, and functional impacts of dysphagia in people with dysphagia and MS. METHODS: In this single-case experimental study with ABA design, two participants with dysphagia caused by MS underwent 12 sessions therapy during 6 weeks following a baseline of 4 evaluation sessions. They were evaluated 4 more times in the follow-up phase after therapy sessions. Scores of Mann Assessment of Swallowing Ability (MASA), DYsphagia in MUltiple Sclerosis (DYMUS), and timed test of swallowing capacity were obtained at baseline, during treatment, and in the follow-up phases. The Dysphagia Outcome and Severity Scale (DOSS) based on videofluoroscopic swallow studies, Persian-Dysphagia Handicap Index (Persian-DHI), and Functional Oral Intake Scale (FOIS) were also completed before and after treatment. Visual analysis and percentage of nonoverlapping data were calculated. RESULTS: MASA, DYMUS, FOIS, and DHI scores indicated significant improvement in both participants. Although the scores of the timed test of swallowing capacity in participant 1 (B.N.) and DOSS in participant 2 (M.A.) showed no changes, considerable improvements including reducing the amount of residue and the number of swallows required to clear bolus were seen in the posttreatment videofluoroscopic records of both participants. CONCLUSION: NMES in conjunction with conventional dysphagia therapy based on motor learning principles could improve the swallowing function and decrease disabling effects of dysphagia on different aspects of life in participants with dysphagia caused by MS.

In recent decades, multiple sclerosis (MS) diseases have been significantly prevalent in some industrial areas of Iran, such as steel industrial areas in Isfahan province (central Iran). In this study, the environmental impacts of two steel mill factories in Isfahan province and their effects on the spread of MS in the region were investigated. To examine the extent of exposure, seasonal dust samples were collected from 15 sites around the two investigated factories. The annual dust deposition rate (DDR) was then determined and the concentrations of lead (Pb), cadmium (Cd), nickel (Ni), cobalt (Co), and manganese (Mn) in the dust samples were measured. Furthermore, the concentration of the mentioned elements was determined in the nail samples taken from 40 MS patients and 40 healthy people (control) living in the study region. The interpolated map extracted from the DDR values showed the highest dust deposition around the two studied steel factories, which decreases with increasing distance from them. The enrichment factor (EF) of heavy metals was the highest at the distance between the two steel factories, decreasing by moving away from them which indicate that these two steel factories are the source of investigated heavy metals in the region. The statistical analysis also revealed significant differences (P < 0.01) between the concentration of heavy metals measured in nail samples taken from MS patients and healthy people. The mean Pb concentration measured in the nail sample taken from MS patients was more than 18 times that of healthy people (93.45 and 5.02 mg/kg, respectively). These results revealed a buildup of heavy metals in the body of MS patients much more than usual, originating from the activities of two investigated steel companies in the region.

Studies among people with multiple sclerosis (pwMS) receiving disease-modifying therapies (DMTs) have provided adequate evidence for an appraisal of COVID-19 vaccination policies among them. To synthesise the available evidence addressing the effect of MS DMTs on COVID-19 vaccines' immunogenicity and effectiveness, following the Cochrane guidelines, we systematically reviewed all observational studies available in MEDLINE, Scopus, Web of Science, MedRxiv and Google Scholar from January 2021 to January 2022 and extracted their relevant data. Immunogenicity data were then synthesised in a quantitative, and other data in a qualitative manner. Evidence from 28 studies suggests extensively lower B-cell responses in sphingosine-1-phosphate receptor modulator (S1PRM) treated and anti-CD20 (aCD20) treated, and lower T-cell responses in interferon-treated, S1PRM-treated and cladribine-treated pwMS-although most T cell evidence currently comprises of low or very low certainty. With every 10-week increase in aCD20-to-vaccine period, a 1.94-fold (95% CI 1.57 to 2.41, p<0.00001) increase in the odds of seroconversion was observed. Furthermore, the evidence points out that B-cell-depleting therapies may accelerate postvaccination humoral waning, and boosters' immunogenicity is predictable with the same factors affecting the initial vaccination cycle. Four real-world studies further indicate that the comparative incidence/severity of breakthrough COVID-19 has been higher among the pwMS treated with S1PRM and aCD20-unlike the ones treated with other DMTs. S1PRM and aCD20 therapies were the only DMTs reducing the real-world effectiveness of COVID-19 vaccination among pwMS. Hence, it could be concluded that optimisation of humoral immunogenicity and ensuring its durability are the necessities of an effective COVID-19 vaccination policy among pwMS who receive DMTs.

BACKGROUND: Multiple sclerosis (MS) is a chronic progressive disease of the central nervous system that affects the patients' quality of life. This research was conducted with the aim of identifying the barriers of quality of life in patients with MS. METHODS: This qualitative study was conducted through a conventional content analysis approach. We used the purposeful sampling with maximum diversity in terms of gender, age, education, marital status and employment. Data were collected through semi-structured interviews with 18 patients with multiple sclerosis referred to the MS Association of Isfahan. Interviews were conducted to the point of information saturation. RESULTS: Through the content analysis of the interviews, we identified 2 main categories and 11 sub-categories. The main categories include intrapersonal problems (physical problems, psychological disorders, turbulent future, functional limitations, job loss and pennilessness), and environmental barriers (disease and treatment process, fatigue of caregivers, information deficiency about MS, family tensions, lack of social support and fun and entertainment). CONCLUSIONS: In order to improve the quality of life in these patients, there is a need for attention and practical measures in the field of identified factors. By removing barriers such as providing educational and counseling services to the patients and their families, adapting the urban structure, providing financial support and adequate insurance coverage, the authorities can take measures to ensure patients' health and improve their quality of life.

BACKGROUND: Some current evidence is pointing towards an association between COVID-19 and worsening of multiple sclerosis (MS), stressing the importance of preventing COVID-19 among people with MS (pwMS). However, population-based evidence regarding the long-term post-COVID-19 course of relapsing-remitting multiple sclerosis (RRMS) was limited when this study was initiated. OBJECTIVE: To detect possible changes in MS clinical disease activity after COVID-19. METHODS: We conducted an observational study from July 2020 until July 2021 in the Isfahan MS clinic, comparing the trends of probable disability progression (PDP) - defined as a three-month sustained increase in expanded disability status scale (EDSS) score - and relapses before and after probable/definitive COVID-19 diagnosis in a cohort of people with RRMS (pwRRMS). RESULTS: Ninety pwRRMS were identified with definitive COVID-19, 53 of which were included in the final analysis. The PDP rate was significantly (0.06 vs 0.19, P = 0.04), and the relapse rate was insignificantly (0.21 vs 0.30, P = 0.30) lower post-COVID-19, compared to the pre-COVID-19 period. The results were maintained after offsetting by follow-up period in the matched binary logistic model. Survival analysis did not indicate significant difference in PDP-free (Hazard Ratio [HR] [95% CI]: 0.46 [0.12, 1.73], P = 0.25) and relapse-free (HR [95% CI]: 0.69 [0.31, 1.53], P = 0.36) survivals between the pre- and post-COVID-19 periods. Sensitivity analysis resulted similar measurements, although statistical significance was not achieved. CONCLUSION: While subject to replication in future research settings, our results did not confirm any increase in the long-term clinical disease activity measures after COVID-19 contraction among pwRRMS.

BACKGROUND: Even within the most populous countries in the Middle East, such as Iran, autoimmune encephalitis cases have been rarely reported. OBJECTIVE: We aimed to describe the demographic, clinical, and paraclinical characteristics of Iranian patients with autoimmune encephalitis positive for anti-neuronal autoantibodies. METHODS: This cross-sectional study included all patients diagnosed with autoimmune encephalitis and referred to our hospital, in Isfahan, Iran, from March 2016 to May 2020. Patients' demographic, clinical, laboratory, radiological, and electroencephalographic features were obtained from their medical records. RESULTS: We identified a total of 39 (21 females, 53.8%) patients with autoimmune encephalitis (mean age = 34.9 ± 12.8 years). The most commonly detected antibody was anti-NMDAR (n = 26, 66.7%), followed by anti-GABABR (n = 8, 20.5%), anti-Zic4 (n = 4, 10.3%), and anti-GAD65 (n = 1, 2.6%) antibodies, in descending order of frequency. Two anti-NMDAR-positive patients had a history of systemic lupus erythematosus (SLE), and four had a prior history of herpes simplex encephalitis. Clinical presentations in patients positive for anti-Zic4 antibodies included cognitive decline (n = 4, 100%), seizures (n = 3, 75%), parkinsonism (n = 1, 25%), and stiff-person syndrome (n = 1, 25%). CONCLUSION: This was the first case series of Iranian patients with autoimmune encephalitis with some interesting observations, including SLE-associated anti-NMDAR encephalitis, as well as an unusual concurrence of anti-Zic4 antibody positivity and cognitive problems, seizures, parkinsonism, and stiff-person syndrome.

BACKGROUND: In recent investigations addressing neurodegenerative diseases, especially multiple sclerosis (MS), the roles of brain-derived neurotrophic factor (BDNF) and interleukin-6 (IL-6) have been examined. METHODS: Forty-five relapsing-remitting MS (RRMS) patients, including 32 IFN-ß-treated and 13 newly identified untreated cases as well as 45 sex- and age-matched healthy controls, were recruited in the study. Plasma levels of BDNF and IL-6 were assessed using the ELISA method. Data were analyzed by SPSS (ver.21). RESULTS: There were significant differences between the case and healthy control groups in terms of the plasma levels of BDNF (p value = 0.044) and IL-6 (p value <0.001). Besides, the treatment with IFN-ß had no significant impact on the level of BDNF or IL-6 in RRMS patients as compared to healthy controls (p value = 0.716 and 0.623 for BDNF and IL-6, respectively). Furthermore, the increase in the plasma levels of BDNF and IL-6 indicated a direct correlation in the case group (r = 0.508, p value = 0.008). In detail, following the classification of the case group into 2 subgroups of IFN-ß-treated and untreated patients, a direct positive correlation was observed between the plasma levels of BDNF and IL-6 in IFN-ß-treated patients (r = 0.495, p value = 0.026). CONCLUSION: The IFN-ß treatment seems not to be effective for upregulating BDNF and IL-6 in RRMS patients.

BACKGROUND: In patients with multiple sclerosis (MS), the disease's complications and manifestations affect a person's ability to function normally and leads to further disruptions in their education, family life, job opportunities, and daily life activities, thereby reduce their quality of life. Different factors as facilitators or inhibitors affect the quality of life in patients with MS. This study aimed to explain the facilitators of quality of life in patients with MS. METHODS: This research applied qualitative methodology, utilizing semi-structured interviews with individuals with MS and their family members/caregivers. Purposeful sampling was done among people who referred to Isfahan MS Association. Participants were selected with a maximum variation in terms of gender, age, education, occupation and marital status. Interviews were continued to reach data saturation. The gathered data were concurrently analyzed by the content analysis technique. MAXQDA software version 10 was used for data management. RESULTS: Saturation was reached after eighteen interviews. A total of three main categories and 8 sub-categories were extracted from the data. The identified facilitators were: personal facilitators (leisure time and coping strategies), interpersonal facilitators (exercise therapy, social support and social organizations) and needs and suggestions for improvement (family therapy, adopting urban architecture and facilities, and supportive systems). CONCLUSIONS: Based on these findings, in order to improve the quality of life in patients with MS, we should pay attention to factors such as leisure time, spirituality and positive thinking, exercise, social support and social organizations. Health professionals, the government, community and families could help to improve patients' quality of life through adapting urban architecture, holding family therapy sessions and providing supportive systems.

OBJECTIVE: The aim of this study was to investigate the frequency of anti-N-methyl-D-aspartate receptor (anti-NMDAR) antibody positivity in patients presenting with transverse myelitis (TM) and/or optic neuritis (ON), to describe their neurologic and radiological characteristics, and to compare these characteristics with those reported in previous studies. MATERIAL AND METHODS: This study included 179 patients (ON: 96, TM: 74, ON and TM: 9) who visited Isfahan Multiple Sclerosis Center from January 2017 to September 2019, for approximately 32 months. The respective neurological examinations were performed. Demographic data of the patients, as well as findings from radiological and serological investigations were obtained. RESULTS: Frequencies of anti-NMDAR seropositivity in patients with TM, ON, and concurrent TM and ON were approximately 3.4%, 1.4%, and 11.1%, respectively. None exhibited any psychiatric symptoms. CONCLUSION: Based on the frequency of seropositivity for anti-NMDAR antibody in our patients, positivity for this antibody appears to be more frequent than previously anticipated in patients presenting with these conditions. We recommend that the anti-NMDAR antibody presence in CSF/serum be checked and considered in addition to the routine examinations performed upon confronting demyelinating conditions such as TM and ON. We suggest considering the term "NMDAR spectrum disorder" to more clearly distinguish the potentially overlapping conditions with different etiologies in patients with CNS disorders.

Multiple sclerosis is the most common progressive neurological disability in young adults. Sexual quality of life is mainly attributed to feelings of sexual attraction, showing interest and participating in sexual activity. The PLISSIT model shows 4 levels of intervention: Permission, limited Information, Specific Suggestions, and Intensive Therapy. The purpose of this study was to investigate the effect of counseling based on the PLISSIT model on the sexual quality of life of married women with multiple sclerosis referring to MS center in 2019. This randomized controlled trial study was conducted on 62 married women with multiple sclerosis. In the experimental group, based on the PLISSIT model, face-to-face counseling was conducted weekly in 4 sessions and each session lasted between 45 and 75 min. The control group received no intervention. Due to ethical issues, after completing the research, an educational guide on the quality of sexual life was given to the control group. The data collection tool was a questionnaire of sexual quality of life containing 18 questions. Data were analyzed using descriptive statistics and SPSS software. The results showed that there was no significant difference between the two groups before the intervention (P > 0.05). However, 2 weeks and 2 months after the intervention, the overall level of sexual quality of life in the experimental group was significantly better than the control group (P < 0.05). This study showed that counseling based on the PLISSIT model could have better results on the quality of life in sex.

Matrix metalloproteinase, especially Matrix metalloproteinase-9 (MMP-9) has vital roles in the disruption of blood barrier, neuroinflammation and pathogenesis of multiple sclerosis (MS) patients. The goal of this study is to estimate the plasma levels of MMP-9 in the first-degree family of MS patients. 35 untreated patients with definite RRMS (Relapsing-Remitting Multiple sclerosis) according to the McDonald criteria, 24 healthy controls (HC) and 26 high-risk families of untreated RRMS patients were enrolled in the study. Plasma levels of MMP-9 were analyzed by ELISA (enzyme-linked immunosorbent assay). Although the plasma protein levels of MMP-9 were elevated significantly in the untreated RRMS group (P < 0.05, P = 0.0203) as compared to the control group, but the family of MS patients was not significance (P = 0.208). The mean plasma MMP-9 concentration for HC, untreated RRMS and high-risk group was 322.268 pg/ml, 611.926 pg/ml and 518.939 pg/ml respectively. MMP-9 was used to understand the role of this biomarker in the pathogenesis of MS in the high-risk group. It found that plasma levels of MMP-9 in the new cases of MS were increased considerably. Confirming the importance of MMP-9 as a predictive marker in the high-risk group will be needed more researches.

BACKGROUND: With the spread of COVID-19, treatment of diseases such as multiple sclerosis (MS) should be resumed with caution due to the disease-modifying therapies (DMTs) used in this subset of patients and the immunoregulatory effects of these drugs. We aim to assess the outcome of COVID-19 infection in MS patients receiving DMTs. MATERIALS AND METHODS: This is a cross-sectional study involving 45 COVID-19-infected patients previously diagnosed with MS. The data regarding their MS status and the type of DMT taken by the patients were extracted from the Isfahan MS Institute registry and were summarized. Diagnosis of MS was based on the 2017 McDonald Criteria, and the diagnosis of COVID-19 was based on computed tomography scan and polymerase chain reaction of nasopharyngeal swabs. RESULTS: Out of the 45 MS patients infected with COVID-19, 5 had unfavorable outcomes. Two patients deceased and the other three had persistent respiratory complications on the 4-week follow-up visit. Hypertension, diabetes, seizures, and rheumatoid arthritis were among the comorbidities that the patients reported. Both patients who died received rituximab as part of their MS treatment. All other patients recovered completely. CONCLUSION: Each different drug category may possess a distinct risk for infection, therefore until robust evidence are available, the safest drug should be utilized or the therapy should be postponed, if possible, to minimize patient risk. Disease-modifying therapy use in MS patients should be cautiously applied as their effect on COVID-19 infection prognosis is not yet studied.
ABSTRACT
Emotional intelligence is a psychological component that may affect happiness level in patients with epilepsy. Given the high prevalence of depression in patients with epilepsy, as well as the limitations of studies in this regard in Iran, the aim of this study was to investigate the effect of an emotional intelligence component program on happiness in patients with epilepsy. METHODS: This randomized clinical trial study conducted on 70 patients with epilepsy who were randomly divided into two experimental and control groups of 35 patients. Emotional Intelligence Training Based on Bar-On Combined Model was provided in eight 90-minute sessions for eight weeks. Data were collected using a two-part questionnaire: demographic data and the Oxford Happiness Questionnaire (OHQ). RESULTS: The mean age of the subjects was 33.3⯱â¯10.4â¯years in the intervention group and 34.4⯱â¯9.3â¯years in the control group. The independent t-test results showed no significant difference between the two groups before the intervention (pâ¯=â¯0.195). The Mann-Whitney test results showed a significant difference between the two groups after emotional intelligence training (pâ¯<â¯0.001). CONCLUSION: Overall, the findings of this study showed that emotional intelligence training led to improvement of happiness in patients with epilepsy. According to the results of the study, it is suggested that training based on emotional intelligence components be used as an approach to improve happiness level in patients with epilepsy.

Background: Multiple sclerosis (MS) is known as a neuroinflammatory disease of the central nervous system (CNS). The neuroinflammation may induce pro-inflammatory cytokines such as Osteopontin (OPN). OPN plays an important role in the inflammation by modulating the T helper1 (Th1) and Th17 responses. Since the exact immune pathogenesis of MS is complex and not well defined and many factors are involved, the need to detect more contributing biomarkers may help in setting new therapeutic strategies.Objective: This study tried to compare plasma OPN levels in relapsing- remitting multiple sclerosis (RRMS) patients during the remission phase with healthy subjects in Isfahan province.Materials and methods: In a case-control study, plasma was collected from the 40 RRMS as well as 38 (age and sex matched) healthy individuals as a control group. PlasmaOPN level was measured and compared between the two groups by Enzyme-linked immunosorbent assays (ELISA).Result: Statistical analysis revealed that plasma OPN level was markedly higher in the case group (RRMS patients during the remission phase) compared with the control group (P- value = 0.039). Our results also showed that there was no statistically significant difference in mean of plasma OPN level among RRMS patients who were treated with interferon (IFN)-ß and those who were not (P- value = 0.332). There was also no correlation between OPN plasma level and EDSS score (r = 0.037, P- value = 0.835), age of onset (r = 0.161, P- value = 0.357) and duration of disease (r = 0.121, P- value = 0.490).Conclusion: Higher OPN plasma level in studied patients suggests that OPN increased in RRMS patients who were in remission phase. It could be hypothesized that plasma OPN level may be increased as part of the pro-inflammatory cytokine milieu taking place in MS patients. OPN may not be specific marker for MS, but targeting it might present promising therapeutic effect to MS patients.
