RESUMO
There is debate on the role of glial fibrillary acidic protein (GFAP) as a reliable biomarker in multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD), and its potential to reflect disease progression. This review aimed to investigate the role of GFAP in MS and NMOSD. A systematic search of electronic databases, including PubMed, Embase, Scopus, and Web of Sciences, was conducted up to 20 December 2023 to identify studies that measured GFAP levels in people with MS (PwMS) and people with NMOSD (PwNMOSD). R software version 4.3.3. with the random-effect model was used to pool the effect size with its 95% confidence interval (CI). Of 4109 studies, 49 studies met our inclusion criteria encompassing 3491 PwMS, 849 PwNMOSD, and 1046 healthy controls (HCs). The analyses indicated that the cerebrospinal fluid level of GFAP (cGFAP) and serum level of GFAP (sGFAP) were significantly higher in PwMS than HCs (SMD = 0.7, 95% CI: 0.54 to 0.86, p < 0.001, I2 = 29%, and SMD = 0.54, 95% CI: 0.1 to 0.99, p = 0.02, I2 = 90%, respectively). The sGFAP was significantly higher in PwNMOSD than in HCs (SMD = 0.9, 95% CI: 0.73 to 1.07, p < 0.001, I2 = 10%). Among PwMS, the Expanded Disability Status Scale (EDSS) exhibited significant correlations with cGFAP (r = 0.43, 95% CI: 0.26 to 0.59, p < 0.001, I2 = 91%) and sGFAP (r = 0.36, 95% CI: 0.23 to 0.49, p < 0.001, I2 = 78%). Regarding that GFAP is increased in MS and NMOSD and has correlations with disease features, it can be a potential biomarker in MS and NMOSD and indicate the disease progression and disability in these disorders.

BACKGROUND: Vaccination constitutes a crucial preventive measure against COVID-19 infection. Concerns have been raised regarding the efficacy of vaccines in multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) patients due to various immunomodulatory medications and potential adverse events that may impact neurological function. This study aimed to explore the implications of COVID-19 vaccination within MS and NMSOD patients and compare it with other neurological disorders (OND). METHOD: In this cross-sectional study conducted in Isfahan, Iran, baseline data and information on COVID-19 infections and vaccinations were collected from MS, NMOSD, and OND patients between September 2021 and September 2022. The predominant neurological disorders identified among OND patients encompassed headache, epilepsy, and Parkinson's disease. Logistic regression analysis was employed to compare COVID-19 vaccination outcomes among different patient groups, presenting odds ratios (OR) with 95% confidence intervals (CI). RESULTS: The study included 1,307 participants, with 738 having MS, 96 having NMOSD, 76 having clinically isolated syndrome (CIS), and 397 having OND. Significantly higher odds of post-vaccination COVID-19 infection were detected in MS (OR = 3.86, p < 0.001) NMOSD (OR = 2.77, p = 0.015) patients than OND patients. The prior history of COVID-19 infection and the type of vaccine administered did not demonstrate significant associations with the likelihood of post-vaccination COVID-19 infection in MS and NMOSD patients (p > 0.05 for all). There were no significant differences in the rates of adverse events in MS, NMOSD, and OND patients, except the second dose, where NMOSD patients had lower odds than OND patients (OR = 0.55, p = 0.019). CONCLUSION: Although the safety profile of COVID-19 vaccination in MS and NMOSD was similar to that in OND, the rates of post-vaccination COVID-19 infection in MS and NMOSD seem higher than OND. These findings highlight the importance of regular serological monitoring and the potential advantages of supplementary vaccine doses in MS and NMOSD patients.
RESUMO
OVERVIEW: Dysphagia has been previously discussed as a potential life-threatening condition secondary to chronic neurological diseases such as multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD). However, its impact on the quality of life (QoL) of patients with NMOSD has never been studied before. This study aims to determine the frequency of dysphagia and its impact on QoL in NMOSD patients in comparison with MS people and healthy individuals. METHODS: Seventy-five MS and sixty-five NMOSD patients with an expanded disability status scale (EDSS) score ≥ 3.5 in addition to 106 healthy controls were enrolled in this cross-sectional study. All the participants completed the self-report dysphagia in MS (DYMUS) and 36-item short-form health survey (SF-36) questionnaires. In case of positive answers to at least one of the questions in DYMUS, they were asked to fill out the dysphagia handicap index (DHI) questionnaire. RESULTS: The frequency of dysphagia in NMOSD, MS, and control groups was 61.54 %, 72.97 %, and 27 %, respectively. Patients with swallowing problems had reduced scores across different swallowing-related QoL domains compared to non-dysphagic patients (p < 0.05). NMOSD (1, IQR [0-3.5]) and MS patients (2, IQR [0-4]) had a significantly higher median total DYMUS score than control (0, IQR [0-1]) (p < 0.01). However, there was no discernible difference between the two patient groups. NMOSD had the highest mean total DHI score (21.22 ± 21), followed by MS (15.25 ± 18.94) and control (7.08 ± 5.12). A significant correlation was seen in the NMOSD group between the DHI total score and the SF-36 total score (r = 0.62, p < 0.05). The DHI and SF-36 subscales showed a strong association as well. The overall SF-36 scores in both the control and MS groups was not significantly correlated with DHI. The generalized linear model analysis showed that the NMOSD group's age (p-value = 0.005), EDSS (p-value < 0.001), and total DYMUS score (p-value = 0.018) significantly affected overall health status. CONCLUSION: The presence of dysphagia significantly impacts the QoL in NMOSD patients, particularly in aspects related to swallowing. These findings underscore the critical need for diligent dysphagia screening and emphasize the importance of educating both caregivers and NMOSD patients about managing this challenging symptom.

BACKGROUND: Depression and anxiety are commonly observed in people with multiple sclerosis (pwMS). There is a growing body of literature supporting the hypothesis that personality traits can influence the mood disorders. This study aimed to investigate the personality traits and their relationships with depression and anxiety among pwMS. METHODS: 234 pwMS were involved in this cross-sectional study. Personality traits, depression, and anxiety were assessed using the NEO Five-Factor Inventory (NEO-FFI) and Hospital Anxiety and Depression Scale (HADS), respectively. Pearson's correlation coefficient and generalized linear model were employed to evaluate the relationships between demographic and clinical characteristics, NEO-FFI, and HADS subscales. RESULTS: In pwMS, longer disease duration was significantly associated with lower level of conscientiousness (ß = - 0.23, p = 0.008) and agreeableness (ß = - 0.2, p = 0.01). Moreover, higher expanded disability status scale (EDSS) of pwMS had a significant relationship with higher level of neuroticism (ß = 0.89, p = 0.01). Increased level of neuroticism was significantly correlated with lower level of extraversion (r = - 0.28, p < 0.001), openness (r = - 0.37, p < 0.001), agreeableness (r = - 0.31, p < 0.001), and conscientiousness (r = - 0.45, p < 0.001). PwMS with higher level of conscientiousness showed more extraversion (r = 0.23, p < 0.001), openness (r = 0.61, p < 0.001), and agreeableness (r = 0.41, p < 0.001). Elevated level of neuroticism was significantly associated with higher level of anxiety (ß = 0.47, p < 0.001) and depression (ß = 0.11, p < 0.001) among pwMS. CONCLUSION: The co-occurrence of depression and anxiety is probably associated with neuroticism among pwMS. Additionally, the impact of personality traits extends to influencing key disease aspects such as physical disability and disease duration in MS.

BACKGROUND: There has been no recent comprehensive epidemiological study on a large and stable population of multiple sclerosis (MS) in Isfahan. Therefore, we conducted this study to estimate the incidence and prevalence of MS in Isfahan province from 1996 to 2021. METHOD: In this population-based study, we utilized the dataset from the Vice-Chancellor's Office of Isfahan University of Medical Sciences, which registers all people diagnosed with MS (PDWM) in Isfahan province, excluding those residing in Kashan city. We measured crude incidence and prevalence of MS, separated by sex, and based on age of MS onset, as well as changes in age of MS onset during observation. RESULTS: A total of 9,909 PDWM were included in our study. The incidence during the time period of 1996-2000 was 5.4/100,000 (1.1/100,000 per year), which subsequently increased to 14.1 (2.8/100,000 per years) and 31.1 per 100,000 (6.2/100,000 per year) during 2001-2005 and 2006-2010, respectively. There was a further increase to 70.9/100,000 (14.2/100,000 per year) in 2011-2015, but it remained stable at 71.8/100,000 (12/100,000 per year) during the period of 2016-2021. In 2016, the age-standardized incidence rates of pediatric-onset, adult-onset, and late-onset MS were 1.8/100,000, 31.4/100,000, and 17.5/100,000, respectively. The prevalence of MS in 2021 was 183.9/100,000. The female/male new case ratio was 4.5 during 1996-2000, decreasing to 4.0, 3.9, 3.9, and 2.9 in the subsequent four five-year periods. The mean age of RRMS onset was 26.3 ± 8.1 between 1990 and 1999, 28.5 ± 8.3 during 2000-2009, and increased to 32.8 ± 9.6 in 2010-2019. CONCLUSION: This study shows that Isfahan has one of the highest incidence rate and prevalence ratio of MS in the region. We observed an increase in the incidence rate during the first decade, followed by stability in the last two five- and six-year periods. Further studies are needed to identify the reasons behind the change in incidence of MS in Iran.

BACKGROUND: There is often a fear of social stigma experienced by people with multiple sclerosis (pwMS), which negatively impacts the quality of their lives (QoL). Currently, no Persian-validated questionnaire is available to assess this issue in pwMS. This study aimed to assess the validaty and reliability of the Persian version of Reece Stigma Scale Multiple Sclerosis (RSS-MS) questionnaire for pwMS. METHOD: This cross-sectional was conducted between January and February 2023 in Isfahan, Iran. The demographic and clinical information and the RSS-MS and Multiple Sclerosis Impact Scale-29 (MSIS-29) questionnaires were recorded from pwMS. The content validity index (CVI) and content validity ratio (CVR) have been used to evaluate validity. To identify the factors supporting the MS-related stigma, an exploratory factor analysis (EFA) was conducted. RESULTS: The present study recruited 194 pwMS. Based on factor analysis, only two factors had eigenvalues ≥ 1.0 and exhibited high internal consistency. The Cronbach's α coefficient for internal consistency of the RSS-MS scale was 0.822. More evidence for the construct validity suggested that having higher levels of stigma is significantly correlated with psychological (r = 0.468, p-value < 0.001) and physical dimensions (r = 0.585, p-value < 0.001) of MSIS-29. Expanded Disability Status Scale, disease duration, and treatment duration did not show a significant correlation with stigma (p-value > 0.05). CONCLUSION: This study indicated that the modified version of the RSS-MS scale in the Persian language showed acceptable validity and reliability for evaluating the stigma among Persian pwMS. Furthermore, this study emphasizes the cruciality of monitoring and addressing stigma among pwMS, as it can potentially enhance medical, psychological, physical, and QoL outcomes.

Background: Fear of relapse and re-infection during the coronavirus disease 2019 (COVID-19) pandemic can affect people with chronic relapsing diseases, such as multiple sclerosis (MS). We evaluated fear of re-infection, anxiety, and relapse during the COVID-19 pandemic in Iranian people with MS. Methods: This multicenter, cross-sectional study was performed in the MS clinic of Sina Hospital, Tehran, Iran, and Hakim Private Hospital, Isfahan, Iran, between January and April 2022. We asked the participants to fill out validated Persian versions of Fear of Relapse Scale (FoR), and Beck Anxiety Inventory (BAI) questionnaires and answer a binary question about their fear of getting reinfected with COVID-19. Results were reported as mean ± standard deviation (SD) for continuous variables or frequencies for categorical variables. For continuous variables which did not have a normal distribution, we reported the median and interquartile range (IQR). Spearman correlation coefficient between anxiety score and FoR score was calculated. An independent samples t-test was used to compare continuous variables. Results: Three hundred and sixty-eight patients participated in this study. The median scores of FoR and BAI were 49.7 and 34.3, respectively. Fifty-three had new relapses in their last infection. Thirty-six percent of the patients had a fear of getting COVID-19 again, and 43% had a fear of relapse during infection. Three hundred and twenty-three had two doses of COVID-19 vaccine; the most frequent type of vaccine was Sinopharm. There was a significant difference between the median FoR scores among patients with and without relapse during the last COVID-19. There was also a significant positive correlation between anxiety score and FoR (r = 0.49, P < 0.001). Conclusion: More than one-third of enrolled cases had fear of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) re-infection. Patients who experienced exacerbation of symptoms even in the form of relapse or pseudo relapse (possible clinical relapse) had a higher fear of infection.
RESUMO
Key clinical message: According to this report, a biopsy revealed a diagnosis of neurosarcoidosis in a patient with a history of MS. The development of the disease can be slowed down by early diagnosis and appropriate treatment. Abstract: Neurosarcoidosis is a rare type of sarcoidosis that affects the central nervous system (CNS). Herein, we present a case of neurosarcoidosis with a history of multiple sclerosis (MS). Based on the pathological findings of the biopsy, a diagnosis of neurosarcoidosis was established. The administration of appropriate treatment at an early stage can assist in decelerating its progression.
RESUMO
Background: Social support and anxiety are essential for patients with chronic diseases such as multiple sclerosis (MS). During coronavirus disease 2019 (COVID-19) pandemic, the psychological well-being of subjects with MS was an important issue, and we designed this study to assess anxiety, resilience, and social support in these patients during COVID-19 pandemic stage. Methods: We used convenience sampling for this study. Inclusion criteria were definite diagnosis of MS based on McDonald criteria and age more than 18 years. Two hundred patients with MS were enrolled. Subjects were asked to fill out valid and reliable Persian versions of Connor-Davidson Resilience Scale (CD-RISC), Beck Anxiety Inventory (BAI), and Perceived Social Support Scale. We also collected demographic data (age, sex, marital status, and occupation), disease duration, and disability level [Expanded Disability Status Scale (EDSS)]. Continuous variables were presented as mean ± standard deviation (SD) (except for EDSS, as its distribution was not normal), and categorical variables were presented as frequencies. Correlation coefficients were calculated. We did a subgroup analysis and compared patients with BAI less than 30 and more than 30 (severe anxiety). A P-value less than 0.05 was considered significant. Results: Mean age and mean duration of the disease were 36.5 ± 9.3 and 6.2 ± 5.4 years, respectively. Mean BAI, social support, and resilience scores were 33.8 ± 11.4, 65.7 ± 16.7, and 62.5 ± 19.4, respectively.There was a significant positive correlation between resilience and social support scales (r = 0.44, P < 0.001), and also a significant negative correlation between resilience and BAI (r = -0.31, P < 0.001). Patients with severe anxiety (BAI > 30) had lower social support scores and resilience (social support: 70.3 ± 13.1 vs. 61.5 ± 18.6, P < 0.001; resilience: 57.3 ± 17.0 vs. 68.2 ± 19.6, P < 0.001) compared to patients with BAI ≤ 30. By considering resilience score as the dependent variable and other variables as independent variables, we found that BAI and social support scores were independent predictors. Conclusion: Social support and anxiety are independent predictors of resilience during COVID-19 pandemic in patients with MS.
