Background: It may take a long time to diagnose multiple sclerosis (MS) since the emergence of primary symptoms. This study aimed to use count regression models to compare their fit and to identify factors affecting delay in the diagnosis of MS.Methods: Data were collected from the Nationwide MS Registry of Iran (NMSRI) for Mazandaran Province, Iran, using census sampling until April 2022. The four models of Poisson regression, negative binomial (NB) regression, zero-inflated Poisson (ZIP) regression, and zero-inflated negative binomial (ZINB) regression were used in this study.Results: In this study on 2894 patients, 74.0% were women, and 8.5% had a family history of MS. The mean ± standard deviation (SD) of the patients’ age was 34.96 ± 9.41 years, and the mean delay in diagnosis was 12.32 ± 33.26 months, with a median of 0 (Q1-Q3: 0-9). The NB regression model showed the best performance, and factors, including a history of hospitalization and the year of symptom onset, had significant effects on a delayed diagnosis. Besides, the Expanded Disability Status Scale (EDSS) score was significantly different before and after 2017; it was also associated with sex, type of MS, and history of hospitalization.Conclusion: The mean diagnostic delay and the mean age of MS diagnosis are critical in Mazandaran Province. Patients with MS develop the disease at an early age and are diagnosed with a long delay. The time of symptom onset is a significant factor in the diagnosis of MS, and in recent years, there have been improvements in the diagnostic process.

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.

Background: Data on perioperative risk stratification in patients with multiple sclerosis (MS) are limited. In this regard, the present study was conducted to investigate Iranian specialists’ approach to surgical counseling for patients with MS (PwMS).Methods: 21 MS specialists were asked about 11 case scenarios with different MS disease statuses, disease-modifying therapies (DMTs), and urgency of the operation. The reasons for refusing surgery or factors that have to be considered before surgery were studied.Results: Overall, Fleiss Kappa was estimated to be 0.091 [95% confidence interval (CI): 0.090-0.093, P < 0.001] indicating a very poor level of agreement among responders.Conclusion: PwMS face surgery for various reasons. Risk assessment of surgery, the effect of various drugs such as anesthetics and DMT on patients, as well as many other aspects of MS are issues challenging the practitioners. Clarifying the various dimensions of these issues requires further research.

Background: Multiple sclerosis (MS) is a neurological disease with a high burden and disability. There are reports of various medications’ side effects on patients with MS. The aim of the study is to determine the characteristics and medicine usage distribution among patients with MS in Chaharmahal and Bakhtiari Province in Iran.Methods: This registry-based cross-sectional study was performed among MS cases in Chaharmahal and Bakhtiari Province. The epidemiological data were collected from the nationwide MS registry of Iran (NMSRI) from 2019 to 2022. The information collected included age, sex, family history, type of MS, age at MS onset and diagnosis, MS symptoms, physical condition, and history of medication use. All tests were performed at a significance level of 0.05 using SPSS software.Results: A total of 416 patients included in this study. Among them, 325 individuals (78%) were women with mean ± standard deviation (SD) of age of 37.35 ± 8.51 years. No significant difference was observed between men and women in terms of age, type of MS disease, family history of MS, and physical condition (P > 0.05). The results showed that the Expanded Disability Status Scale (EDSS) score in female patients (1.41) was different from the EDSS score in male patients (1.77) (P < 0.05). Most of the patients often used interferon beta (IFN-β).Conclusion: The results provided new insight into the epidemiology and medicine patterns of patients with MS in Chaharmahal and Bakhtiari Province. The epidemiological situation of MS in this province is similar to other parts of Iran. Planning according to national programs is suggested for the management and control of MS.

Background: Fingolimod is approved in relapsing-remitting multiple sclerosis (RRMS) with the recommended dose of 0.5 mg daily. To tackle possible adverse events, some clinicians may reduce the dose of fingolimod, mainly in the alternate-day form. We systematically reviewed the literature for efficacy measures of this method.Methods: PubMed (Medline®), Web of Science, Embase, Scopus, and the Cochrane Library databases were searched until April 9, 2021. Clinical studies (other than case reports and case series), in English, were included. Then, publications concerning alternate dose fingolimod (including every other day, every two or three days) were selected. Those studies concerning reduced daily dose (any daily dose less than 0.5 mg/day) were excluded to focus on alternate dosing.Results: Four observational studies were included. Data on Ohtani et al. study were limited. Three other studies were of good quality based on the Newcastle-Ottawa Scale. A total of 296 patients on the standard dose were compared to 276 patients on the alternate dosage. The most common reason for switching to the alternate dose was lymphopenia, followed by elevated liver enzymes. Two studies concluded that the alternate dosing could be a safe, yet effective strategy in patients with intolerable adverse effects of daily dose. However, Zecca et al. warned about the high possibility of disease reactivation. Due to the differences in outcome measures of the studies, meta-analysis was not applicable.Conclusion: This systematic review highlights the ambiguity of evidence on safety and efficacy of alternate dosing of fingolimod, encouraging further research on the subject.

Background: Glatiramer acetate (GA) and Interferon (IFN) beta-1a are used as first-line disease-modifying treatments for multiple sclerosis (MS). In this systematic review, we summarized case reports and case series of adverse side effects of GA and IFN beta-1a in MS patients.Methods: Without any restrictions, PubMed, Scopus, Web of Sciences, and Embase databases, and gray literature were systemically searched until June 2022. Articles were screened and data were extracted based on a predefined table by two independent reviewers. The risk of bias was assessed using the Joanna Briggs Institute (JBI) tool.Results: We identified 2103 records from the preliminary search. After deduplication and screening, 172 articles were included in the systematic review. In total, 229 individuals (52 men, 173 women, and 4 unknown) were included in the study. The most common adverse events were cutaneous (32.75%), hepatic (13.54%), allergic (8.3%), and neurological (5.68%) side effects. Furthermore, most reported side effects were related to autoimmune diseases or hypersensitivity reactions.Conclusion: GA and IFN beta-1a are associated with several side effects which may be related to the immunomodulatory function of medication or other injection-related reactions.

Background: People with multiple sclerosis (MS) and their physicians recognize cognitive retention as an important desired outcome of disease-modifying therapies (DMTs). In this study, we attempted to gather the opinions of Iranian MS experts regarding the treatment approach toward clinical cases with different physical and cognitive conditions.Methods: Opinions of 20 MS specialists regarding the best approach to 6 case scenarios (with different clinical, cognitive, and imaging characteristics) were gathered via a form.Results: The estimated kappa of 0.16 [95% confidence interval (CI): 0.159-0.163; P < 0.001] suggested a poor degree of agreement on the treatment choice among the professionals.Conclusion: Although most specialists agreed with treatment escalation in cases with cognitive impairment, there was no general agreement. Furthermore, there was not enough clinical evidence in the literature to develop consensus guidelines on the matter.

Background: Coronavirus 2019 (COVID-19) vaccination is recommended for people with multiple sclerosis (MS). This study evaluated the side effects of Sinopharm and AstraZeneca vaccines in MS patients.Methods: In this cross-sectional study among MS patients in Kermanshah province, Iran, who received Sinopharm or AstraZeneca vaccine, sampling was performed through convenience sampling according to the nationwide MS registry of Iran (NMSRI). Demographic and clinical information of the participants and data on the side effects of vaccines were collected by telephone after the first dose. The data were analyzed in SPSS software.Results: 264 vaccinated MS patients (217 with Sinopharm and 47 with AstraZeneca) were studied. In the Sinopharm and AstraZeneca groups, respectively, 58.5% and 73.3% of patients had side effects that were not significantly different between the 2 groups (P = 0.064). In the AstraZeneca group, the severity of side effects and prevalence of taking painkillers were significantly higher (P < 0.050) and the interval between vaccination and side effects onset was significantly shorter (P = 0.013). The most commonly experienced side effects in the Sinopharm group were fatigue (29.0%), myalgia (24.9%), fever (24.0%), and headache (21.7%), and in the AstraZeneca group were fever (59.6%), chills (51.1%), myalgia (40.4%), and fatigue (34.0%). Logistic regression by controlling for confounding variables showed that considering some factors as confounding factors did not show a significant difference between the 2 vaccines in the experience of side effects (P = 0.104).Conclusion: The AstraZeneca vaccine caused more severe side effects in MS patients than the Sinopharm vaccine. Most of the side effects were moderate in severity and transient.

Background: Multiple sclerosis (MS) is a debilitating, non-traumatic, neurological disorder in young adults and can reduce quality of life (QoL) by interfering with the ability to work, leisure activities, and routine living tasks. Various studies have shown the dissatisfaction of people with MS in different areas of care services. Regarding the patients' dissatisfaction with care services, in this study, we sought to identify the care challenges of MS patients in Iran. Methods: This cross-sectional study was conducted in 2016-2018 using a researcher-made questionnaire (designed by MS Specialists in an MS research center). The questionnaire examines the care challenges in four areas: 1) costs of medication, hospitalization, and rehabilitation services, 2) family support, insurance system, and job protection, 3) access to transportation system and treatment team, 4) quality of the provided care and services.Results: Completed questionnaires were received from 945 respondents. The mean age of responders was 35.92 years. In total, 731 (77.8) participants were women and 208 (22.2) were men. Academic education was reported among 615 (65.3) participants and 367 (40.2) were employed during the study, while 99 (10.5) of the subjects were not able to walk a minimum of 20 meters. The prioritization of care services challenges is as follows: the cost of pharmaceutical services (49.1), lack of telephone counseling (47.4), uninsured home rehabilitation (44.7), lack of qualified care centers (41.2), and rehabilitation costs (40.2).Conclusion: We found that patients who could not walk at least 20 meters and unemployed individuals had more problems and lower QoL. The patients who had non-academic education had more challenges with the cost of medication, transportation, and lack of familial support. This study shows the challenges of MS patients in receiving health care in Iran that vary in age, education, employment, and ability to walk. As the abovementioned challenges are of great importance in determining the QoL of people with MS, an appropriate solution is provided in this study to overcome these challenges.

Background: It seems that patients with multiple sclerosis (MS) are at a higher risk for coronavirus disease 2019 (COVID-19) implications due to being subjected to immunomodulatory or immunosuppressive treatments. Besides, obesity as a risk factor may lead to more adverse consequences. The relationship between obesity and COVID-19 morbidity and outcomes in Iranian patients with MS still remains unclear.Methods: A cross-sectional study was conducted in Sina Hospital, Tehran, Iran. Patients with MS were asked to complete an online questionnaire in the Google Form format. Demographic information, clinical information including MS disease-related factors, COVID-19-related factors, and anthropometric information were recorded. Totally, 492 patients filled the questionnaire during two weeks in November 2021, by the response rate of 21.6%. Body mass index (BMI) was categorized based on the standard classification of the World Health Organization (WHO). The logistic regression was used to examine the risk of morbidity and chi-square test/one-way analysis of variance (ANOVA) was employed to determine the difference regarding severity and symptoms among groups.Results: In the fully adjusted model, the odds ratio (OR) of COVID-19 morbidity in class II obese participants was significantly 5.41 times higher than that in the normal BMI group [OR: 5.41, 95% confidence interval (CI): 1.00-29.09]. COVID-19 severity was significantly different among BMI groups (P = 0.024). Respiratory symptoms (P = 0.05) as well as gastrointestinal (GI) symptoms (P < 0.01) of COVID-19 were more prevalent among class I and class II obese patients compared with overweight, normal weight, and underweight groups. Moreover, no one in the class I and class II obesity groups reported COVID-19 morbidity without any symptoms (P = 0.04).Conclusion: The results of the current study support the view that obesity could play a key role in susceptibility to COVID-19 morbidity and severity of the symptoms in patients with MS. The findings recommended that neurologists pay more attention to patients' BMI during this pandemic.

Background: Fatigue is a common complaint of patients with multiple sclerosis (MS), adversely affecting their quality of life. There is a lot of evidence showing that carnitine deficiency is linked to fatigue development and severity in some conditions. This study aimed to evaluate the association between free L-carnitine serum levels and the severity of fatigue in patients with MS.Methods: This case-control study included 30 patients with relapsing-remitting MS (RRMS) in two age-matched equal-number groups according to the presence or absence of fatigue. Fatigue was scored using the valid questionnaire of Fatigue Severity Scale (FSS) and serum level of free L-carnitine was measured simultaneously. Finally, the association between serum level of free L-carnitine and fatigue severity was evaluated in patients with MS.Results: The mean value of FSS in patients with fatigue was 48.80 ± 8.55, which was nearly two-fold higher than the group without fatigue. We found a significant correlation between the serum level of free L-carnitine and FSS and showed that the patients with fatigue had a significantly lower serum level of free L-carnitine compared to patients without fatigue (P < 0.001).Conclusion: Present study demonstrated that patients with lower serum levels of free L-carnitine were more likely to experience fatigue. We recommend that a higher dietary intake of carnitine might be a useful complementary treatment for MS-related fatigue.

Background: This study was conducted to evaluate the relationship between retinal layer thickness (RLT) and cognition in patients with multiple sclerosis (MS).Methods: We searched PubMed, Scopus, Embase, Web of Science, and Google Scholar. The search strategy included the MeSH and text words as [“ora serrata” OR “retina” OR (“coherence tomography” AND “optical”) OR “OCT tomography” OR (tomography AND OCT) OR “optical coherence tomography” OR “OCT” OR “retinal thickness” OR “inner plexiform layer” OR “nerve fiber layer” OR “ganglion cell layer” OR “inner nuclear layer” OR “outer plexiform layer” OR “outer nuclear layer” OR “external limiting membrane” OR “inner segment layer” OR “outer segment layer” OR “retinal pigment epithelium”] AND [“cognition”* OR “cognitive function”* OR (function* AND cognitive)] AND [(sclerosis AND multiple) OR (sclerosis AND disseminated) OR "disseminated sclerosis" OR "multiple sclerosis" OR "acute fulminating"].Results: The literature search revealed 1090 articles; after deleting duplicates, 980 remained. Finally, 14 studies were included. Totally, 1081 patients were evaluated. Mean age ranged from 31 to 55 years. In some studies, there was a correlation between cognition and retinal thickness, while others did not confirm this finding. Some authors found cognitive impairment (CI) in patients with MS with RLT.Conclusion: The results of this systematic review show that there are discrepancies between the results of studies regarding the relationship between RLT and cognition status in patients with MS. Further studies with more included original studies and meta-analysis are recommended.

Background: The purpose of this study was to evaluate the validity and reliability of the Persian version of Patient Determined Disease Steps (PDDS) in both patients with multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD).Methods: One hundred and forty-five patients were enrolled between May and September 2020 by consecutive sampling. Participants were asked to complete timed 25-foot walk (T25FW), 12-item Multiple Sclerosis Walking Scale (MSWS-12), and Multiple Sclerosis Quality of Life-54 (MSQOL-54). Patients also completed Timed Up and Go (TUG) and six-minute walk (6MW) tests. Construct validity was assessed by calculating correlation between PDDS and ambulatory and demographic items. The intra-class correlation coefficient (ICC) was used to evaluate reliability.Results: One hundred and eleven patients with MS and 34 with NMOSD with disease duration of 7.6 ± 5.8 years were enrolled. Twenty-seven percent were men and mean Expanded Disability Status Scale (EDSS) was 1.8 ± 1.8.There was a significant positive correlation between EDSS and PDSS (rho = 0.64, P < 0.001) which was evident in MS subgroups and NMOSD [secondary progressive MS (SPMS): rho = 0.64, P < 0.001; relapsing-remitting MS (RRMS): rho = 0.47, P < 0.001; NMOSD: rho = 0.52, P = 0.001]. PDDS had also significant positive correlation with TUG, T25FW, and MSWS-12. PDDS had also significant negative correlation with 6MW test. PDDS had weak correlation with demographic variables. The ICC was calculated as 0.99 for PDDS.Conclusion: The Persian version of PDDS provides valid and reliable instrument to assess MS/NMOSD-related disability.

Background: Fatigue is a common complication associated with multiple sclerosis (MS). The aim of this study was to evaluate the impact of dalfampridine and amantadine on fatigue in patients with MS.Methods: This was a randomized, double-blind, clinical trial on patients with MS. The recruited patients were adults (≥ 18 years old) diagnosed with MS; their Expanded Disability Status Scale (EDSS) was between 0.0 and 5.5, and their fatigue was confirmed by the Modified Fatigue Impact Scale (MFIS). They were randomly assigned to the amantadine (100 mg twice daily) and dalfampridine (10 mg twice daily) for eight weeks. The primary outcome was the improvement of fatigue score, and the secondary outcome was assessment of quality of life by the Short-Form Health Survey (SF-36) and any reported side effects.Results: A total of 69 patients were recruited, and 54 of them were analyzed. The mean MFIS significantly improved in both groups after one and two months compared to baseline: amantadine: first month: 40.63 ± 14.35 (P = 0.040), second month: 36.56 ± 17.12 (P = 0.010); dalfampridine: first month: 38.29 ± 15.23 (P = 0.001), second month: 34.26 ± 18.30 (P = 0.001). However, the amount of changes from baseline was not significantly different (amantadine, P = 0.090; dalfampridine, P = 0.130). The amount of changes in quality of life showed no significant improvement (P = 0.210).Conclusion: The results showed that dalfampridine was not different with amantadine in improving fatigue in patients with MS; besides, it showed an acceptable safety profile. Therefore, it can be considered as a possible beneficial therapeutic agent in MS fatigue.

Background: Despite special global considerations which have been made to prioritize vaccination of people with multiple sclerosis (MS), some are reluctant to get vaccinated. This study was aimed to evaluate the attitude toward coronavirus disease-2019 (COVID-19) vaccine and its probable correlations.Methods: Considering the study objectives, two valid questionnaires including Fear of COVID-19 Scale (FCV-19S) and attitude questionnaires were administered pre and post COVID-19 vaccination among people with MS.Results: The questionnaires were administered among 349 people with MS pre and post vaccination. The mean age of participants was 38.78 ± 8.68 (range: 19 to 64) years. They all received the first dose of COVID-19 vaccine (Sinopharm). Although about 90% of participants felt satisfied after getting vaccinated and respected the preventive actions like social distancing and wearing face mask after vaccination, about 40% of them did not recommend vaccination to other patients. None of the demographic data was predictor of attitude score in COVID-19 vaccine and the only effective factor regarding fear of COVID-19 among people with MS was gender (P = 0.001). It was found that the more a patient’s fear score was, the more he/she felt satisfied after vaccination. Those patients who had got the influenza vaccine last year felt more satisfied with the vaccine and accepted the COVID-19 vaccine easier than others.Conclusion: This study revealed that there was an inverse correlation between fear of coronavirus and less trust in the vaccine in patients with MS. However, it should be mentioned that the patients felt more satisfied after COVID-19 vaccination.

Background: Cognitive impairments in patients with multiple sclerosis (MS) are suggested as a prognostic factor for disease development, and consequently higher disability and more deficits in daily and social activities. In this regard, we aimed to investigate the association between quality of life (QOL) and cognitive function in patients with MS.Methods: We conducted a cross-sectional study on patients with relapsing-remitting MS (RRMS). General characteristic variables were carried out, and then all patients underwent assessments such as Multiple Sclerosis Quality of Life-54 (MSQOL-54), Minimal Assessment of Cognitive Function in Multiple Sclerosis (MACFIMS), Expanded Disability Status Scale (EDSS), Beck Depression Inventory-II (BDI-II), and North American Adult Reading Test (NAART).Results: In the present study, a total of 92 patients, including 76 women with a mean disease duration of 6.82 ± 4.80 years were involved. Results of simple Pearson correlation revealed a significant positive relation between California Verbal Learning Test (CVLT) total learning with MSQOL mental health (r = 0.267, P = 0.017) and physical health (r = 0.299, P = 0.007). After adjusting for potential confounders, there was a negative correlation between MSQOL mental health with Delis-Kaplan Executive Function System (D-KEFS) (r = -0.303, P = 0.015) and Judgment of Line Orientation (JLO) (r = -0.310, P = 0.013). Besides, MSQOL physical health was negatively associated with Brief Visuospatial Memory Test-Revised (BVMT-R) in the adjusted model (r = -0.270, P = 0.031).Conclusion: There is a statistically significant association between specific aspects of cognitive decline and QOL. Therefore, more attention should be paid to cognitive impairment in patients with MS as based on our findings, it is significantly associated with QOL.

Background: Now that the majority of the population has been immunized with two-dose vaccines, debates over the third booster dose have been raised. We studied the viewpoint of cases with multiple sclerosis (MS) on this matter.Methods: In a cross-sectional study, a google form containing questions about participants’ characteristics, the history of coronavirus disease 2019 (COVID-19) infection and vaccination, and opinions on the third dose was designed.Results: Of 1067 responders, only 16 (1.5%) were not vaccinated at all. The most used vaccine type was Sinopharm BBIBP COVID-19 vaccine (BBIBP-CorV) (n = 1002, 93.9%). Generally, 58 (5.4%) cases were hospitalized due to COVID-19. Of those with full vaccination, 134 (13.3%) got COVID-19 infection after the second dose. Only 13 participants (1%) did not agree with the third dose, while 564 (53.0%) believed that a booster dose was needed. Of all, 488 (45.7%) declared that they did not have a final idea and would follow the instructions by the experts. A significant association was found between not receiving the first two doses and not believing in the third dose (P = 0.001). 692 patients declared their reasoning for the importance of the third dose. All the cases who thought the administered vaccine was not efficient enough had received Sinopharm BBIBP-CorV. Those who got infected after full vaccination were more uncertain about the efficacy of the vaccine [odds ratio (OR): 2.6, 95% confidence interval (CI): 1.6-4.2].Conclusion: It seems that the majority of the Iranian patients with MS expect the authorities to administer a third booster dose, especially if scientifically validated.

Background: Sleep disorders are major but neglected symptoms in patients with multiple sclerosis (MS). This study aimed to describe the sleep status in patients with MS.Methods: We selected mildly-disabled [Expanded Disability Status Scale (EDSS) score < 4] patients with relapsing-remitting MS (RRMS). After determining the level of vitamin D in a blood sample of the patients, the validated Persian versions of Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), and snoring, tiredness, observed apnea, high blood pressure, body mass index (BMI), age, neck circumference, and gender (STOP-Bang) questionnaires were filled and the sleep condition was described. Besides, the impact of age, sex, disease duration, and EDSS on sleep status was determined.Results: 37.87% of 103 included patients with MS had poor sleep quality. 21.35% rate of subthreshold, 10.67% rate of moderate, and 1.94% rate of severe insomnia were also observed. Only 1.94% of patients had a high risk of obstructive sleep apnea (OSA). There was a significant relation between Beck Depression Inventory (BDI) score with ISI (r = 0.45, P < 0.01), PSQI (r = 0.53, P < 0.01), and STOP (r = 0.20, P = 0.03). A significant correlation between STOP with BMI (r = 0.24, P = 0.01) and age (r = 0.21, P = 0.03) was also observed. Sleep status was not significantly different in groups of the patients based on vitamin D, overweight, or sex.Conclusion: Poor sleep quality is a common finding among mildly-disabled patients with MS. There is also a 33.99% rate of subthreshold or clinical insomnia in different severities. Quality of sleep and insomnia is not significantly correlated to BMI, level of vitamin D, and sex in patients with MS.

Background: A growing number of clinical trials have investigated the role of diet in multiple sclerosis (MS) patients. We systematically reviewed the literature for clinical trials to assess the impact of different kinds of diets on MS-related outcomes.Methods: We searched MEDLINE, EMBASE, and Web of Science for relevant studies published before July 2019. The clinical trials included a defined dietary intervention and MS outcomes, including fatigue, relapse rate (RR), quality of life (QOL), and disability.Results: In the present review, 15 trials on 669 MS patients were included. The 2 plant-based diet trials, 1 was low-fat and the other was low-calorie, included in the review showed a large effect (ES: 0.6 to 0.7) on fatigue compared to the regular diet. The other plant-based diet was a low-protein diet and showed moderate to large effects on disability and RR compared to the Western diet. Moreover, 2 studies showed the clinically meaningful effects of the ketogenic diet (KD) on QOL and disability compared to the regular diet. In addition, 2 studies compared fish oil (FO) to placebo and found a small effect on disability (ES: 0.1 to 0.3). There were 2 studies that evaluated evening primrose oil and hemp seed oil and showed medium to large effect (ES: 0.7 to 1.5) on RR compared to olive oil. Finally, we found 2 studies that showed high flavonoid cocoa had a moderate effect (ES: 0.4) on fatigue and a small effect (ES: 0.04) on QOL compared to low flavonoid cocoa.Conclusion: Plant-based diet is a backbone for dietary recommendations in MS patients although low-fat, low-calorie, and KD diets with the addition of fish oil, vegetable oil, and flavonoids could be helpful.

Background: Depression and anxiety are the most prevalent psychological symptoms in patients with multiple sclerosis (MS) and have a significant impact on quality of life (QOL) and disability progression in the patients. Therefore, it is very important to find ways to reduce the impact of these disorders on patients with MS. The data suggest that self-disclosure may be beneficial in improving symptoms of depression and anxiety in many chronic diseases. Due to the scarcity of related studies, this cross-sectional research aimed to evaluate the relations between self-disclosure, anxiety, and depression in patients with MS. Methods: 112 patients with MS from several referral outpatient MS clinics participated in the study. Data were extracted using socio-demographic questionnaire to determine clinical variables and patient characteristics, Distress Disclosure Index (DDI) to assess self-disclosure, Hospital Anxiety and Depression Scale (HADS) to evaluate mood states, and Kurtzke Expanded Disability Status Scale (EDSS) recorded by an experienced neurologist. Results: Multiple linear regression analysis with controlling disease variables demonstrated distress disclosure as an independent factor to predict anxiety and depression in the patients (P < 0.05). Results also presented a significant, positive relationship between hospitalization history and disability levels with anxiety and depression. These findings clearly state that these two variables can accurately predict a heightened state of anxiety and depression in patients with MS. Conclusion: This study provides empirical support for the positive role of disclosure in decreasing the negative emotions in MS. Further studies are needed to clarify the effects of disclosing MS in different cultural and situational contexts.

Background: Pediatric-onset multiple sclerosis (POMS) is an autoimmune demyelinating disorder of the central nervous system (CNS), affecting individuals younger than 18 years of age. We sought to characterize the epidemiological and clinical features of patients with POMS in Isfahan, Iran, from April 1997 to March 2020.Methods: The medical records of patients with POMS in the databases of Isfahan Department of Public Health and Isfahan Multiple Sclerosis Society (IMSS) were retrospectively reviewed. The 2006 and 2016 Isfahan Province population censuses were used as reference values for assessing the temporal trend of POMS.Results: From April 1997 to March 2020, 509 individuals under18 years of age were diagnosed with POMS in Isfahan. 404 of these patients (79.4%) were girls, and 105 patients (20.6%) were boys (a female to male ratio of 3.85:1). Most of the patients (83%) were monosymptomatic at onset, with optic neuritis and brainstem-cerebellar disorders being the most frequent initial presentations. Mean ± standard deviation (SD) of age at disease diagnosis was 15.8 ± 2.5 years (ranging from 3 to 18, mode = 18). From April 2019 to March 2020, the crude prevalence and the crude incidence rate of the POMS were 5.42 per 100000 and 1.86 per 100000, respectively. Poisson regression analysis revealed a 3.4% increase in the incidence rate of POMS from April 1997 to March 2020 [relative rate:1.034, 95% confidence interval (CI): 1.021-1.048].Conclusion: The female to male ratio in our cohort was significantly higher than any other studies conducted previously. The high female to male ratio and increasing incidence of the disease suggest increasing regionalization of care.

Background: The national multiple sclerosis (MS) registry is aimed at monitoring and improving quality of care and providing feedback to improve health outcomes by systematic recording of data. In 2018, the nationwide MS registry of Iran (NMSRI) was initiated for collecting epidemiological data and information on health care provision for patients with MS. The aim of the current study was to introduce the role of implementing coronavirus disease 2019 (COVID-19) scale-up registry protocol in NMSRI and arrange the national MS generality with information obtained during the COVID-19 pandemic. Methods: The NMSRI group set up a program with crucial elements to collect the data of patients with MS who developed COVID-19. All MS cases with confirmed diagnosis of COVID-19 were enrolled in this study. New elements were considered to be added into the dataset, including demographic characteristics, definite diagnosis of COVID-19 and its symptoms, history of comorbidities, history of medications and hospitalization, changes in magnetic resonance imaging (MRI), and infection outcomes. Results: The COVID-19 data collection program was designed in NMSRI to collect data of MS cases with COVID-19 infection. The data collection protocol was explained to neurologists through an online training workshop. To the date of the study, 21 centers from 17 provinces of Iran were involved in the COVID-19 databases promoting NMSRI and 612 participants were registered successfully. Conclusion: We extended an agreement on data collection and developed it in NMSRI with various contributors to discover a critical need for COVID-19 awareness and monitor clinical training in MS.
