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: Failure in early diagnosis of myasthenia gravis (MG) and the risks of taking certain medications and undergoing surgery and anesthesia can lead to severe respiratory disorders and death. However, there are therapeutic measures that significantly control the disease and improve individual’s functionality.Methods: First, an expert panel was formed, and a needs assessment questionnaire was prepared for the information elements and the capabilities required for the application and provided to neurologists with a subspecialty fellowship in neuromuscular diseases. Then, based on the analyzed results, the application was designed and created in 2 versions (physician and patient), and in 2 languages (Persian and English). Eventually, a questionnaire for user interaction and satisfaction was provided to 5 relevant physicians to evaluate the application.Results: The results showed that neurologists considered all items of the needs assessment questionnaire to be 100% essential. The capabilities of the application included registering the medication name and dose, recording symptoms and complaints by the patient, completing standard questionnaires, online chat, medication reminder, sending alerts to the doctor when the patient is unwell, and providing a variety of reports. The usability evaluation showed that neurologists evaluated the application at a good level with the average score of 8.23 ± 0.47 (out of 9 points).Conclusion: In the long run, using this technology can reduce costs, improve patients’ quality of life (QOL) and health care, change health behaviors, and ultimately, improve individual’s health.

Background: Migraine is a multifactorial neurological disorder characterized by frequent moderate to severe intensity headaches. The genetic variations in synaptic and post-receptor signalling proteins have direct effect on the process of serotonergic neurotransmission.Methods: We aimed to investigate the genetic association of serotonin transporter (SERT) 5-hydroxytryptamine transporter-linked promoter region (5-HTTLPR) polymorphism and migraine risk in South-Indian population. A total of 304 subjects with migraine including with aura (MA) and without aura (MO) and 308 controls were included in the present study. The single nucleotide polymorphism (SNP) was detected using polymerase chain reaction (PCR) and confirmed by deoxyribonucleic acid (DNA) sequencing.Results: The genotyping analysis revealed insignificant relationship with migraine subjects when compared with controls (P > 0.05). The minor ‘S’ allele showed no association with odds ratio (OR) = 1.23 [95% confidence interval (CI): 0.90-1.66], heterozygote with OR = 1.18 (95% CI: 0.82-1.69), and homozygote with OR = 1.51 (95% CI: 0.52-4.35).Conclusion: Further clinical studies are required to validate the results of SERT 5-HTTLPR promoter polymorphism in diverse ethnic descents especially in Asian populations.

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: We believe that designing a new tool which is comparable in terms of both sensitivity and specificity may play an important role in rapid and more accurate diagnosis of acute ischemic stroke (AIS) in prehospital stage. Therefore, we intended to develop a new clinical tool for the diagnosis of AIS in the prehospital stage.Methods: This was a cross-sectional diagnostic accuracy study. All patients transferred to the emergency department (ED) who underwent brain magnetic resonance imaging (MRI) with impression of AIS were evaluated by 9 clinical tools for stroke diagnosis in the pre-hospital phase including Rapid Arterial Occlusion Evaluation (RACE), Cincinnati Prehospital Stroke Scale (CPSS), Los Angeles Prehospital Stroke Screen (LAPSS), Melbourne Ambulance Stroke Screen (MASS), Medic Prehospital Assessment for Code Stroke (Med PACS), Ontario Prehospital Stroke Screening Tool (OPSS), PreHospital Ambulance Stroke Test (PreHAST), Recognition of Stroke in the Emergency Room (ROSIER), and Face Arm Speech Test (FAST), and totally 19 items were reviewed and recorded. The new clinical tool was developed based on backward method of multivariable logistic regression analysis. The discrimination power of the new clinical tool for diagnosis of AIS was assessed with the area under the receiver operating characteristic curve (AUC-ROC).Results: Data from 806 patients were analyzed; of them, 57.4% were men. The mean age of the study patients was 66.9 years [standard deviation (SD) = 13.9]. In the multivariable model, 8 items remained. The AUC-ROC of the new clinical tool was 0.893 [95% confidence interval (CI): 0.869-0.917], and its best cut-off point was score ≥ 3 for positive AIS. At this cut-off point, sensitivity and specificity were 84.42% and 79.72%, respectively.Conclusion: We introduced a new nomogram-based clinical tool for the diagnosis of AIS in the prehospital stage, which has acceptable specificity and sensitivity; moreover, it is comparable with previous tools.

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: 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.
