ABSTRACT
Background: People with chronic diseases of the immune system, such as multiple sclerosis (MS), are at risk for Covid-19 disease. However, more research is needed with long-term follow-up. The aim of the study was to follow up people with MS (PwMS) for up to three months after AstraZeneca vaccination for the recurrence of MS and Covid-19 infection. Method(s): This study was a case study (descriptive-analytical) of follow-up type. The study population was PwMS over 18 years of age in Kermanshah province who received both doses of the AstraZeneca vaccine. This study was conducted from August to November 2021. Sampling was done with existing methods based on the National MS Registry of Iran (NMSRI). Demographic information of patients was extracted from NMSRI. A researcher-made form was used to collect information by telephone three months after vaccination about clinical characteristics, Covid-19 infection, and recurrence of MS. Data were analyzed using SPSS-25 software. Result(s): Study participants were 40 MS patients with a mean (SD) age of 39.27 (8.8) years, including 32 (80.0%) women. A mean of 9.39 (4.6) years had passed since The patients were diagnosed with MS, and 29 (76.4%) had RR type MS. Four patients (10%) relapsed between the second dose and three months later, of whom two (50%) had sensory symptoms, one (25%) had optic nerve involvement, and one (25%) had motor symptoms and pyramidal pathway involvement. The symptoms of Covid-19 were mild in three patients (10%), while severe symptoms developed in one patient (10%) who received rituximab. Among the patients, no cases of thrombosis were observed. Infusion therapy, a leg fracture, and kidney stones were the only hospitalized cases. Conclusion(s): Covid-19 and MS relapse prevalence did not differ significantly in the three months before and after vaccination. There is a need for further studies with a longer follow-up period.Copyright © 2022 Razazian et al. Published by Tehran University of Medical Sciences.
ABSTRACT
Background: Coronavirus Disease 2019 (COVID-19) is a highly contagious disease that resulted in 4533645 deaths until September first, 2021. Multiple Sclerosis (MS) patients receive immunosuppressive drugs. Thus, there is a concern that these drugs will reduce the patient's immune system resistance against COVID19. Objective(s): This study aimed to evaluate the epidemiology of COVID19 and its impact on MS patients in our university hospital in Tehran City, Iran. Material(s) and Method(s): A cross-sectional study was conducted based on hospital-based registry data from May 2020 to March 2021. Among more than 500 registered MS patients in Imam Khomeini Hospital in Tehran City, Iran, referring within our study period, 84 patients reported SARS-COV2 infection. The diagnosis of MS was confirmed by the McDonald criteria. Moreover, the diagnosis of COVID-19 in MS patients was established by the real-time-PCR technique and chest computed tomography. Result(s): Out of 84 MS patients with SARS-COV2 infection, 55(65.5%) were women, and their mean age was 37.48 years. The most commonly used medications by MS patients were Rituximab 20 (26.3%) and Dimethyl Fumarate 14(18.4%). Totally, 9(10.8%) of the patients needed to be hospitalized due to COVID-19, with a mean hospitalization duration of 5.88 days. A total of 1 (1.2%) death was reported. Conclusion(s): Compared to the healthy population, COVID-19 is not more serious in MS patients. Most MS patients with COVID-19 infection were not hospitalized and continued their medication during the infection.Copyright © 2022 The Authors.

ABSTRACT
Background: Disease-modifying drugs (DMDs) are an inseparable part of multiple sclerosis (MS) management, which have dramatically changed the prognosis and course of the disease. A change during DMD therapy, which includes switching or stopping (temporary or permanent) medication, can manipulate the goals and has various causes such as side effects, ineffectiveness of treatment, patient's preference, presence of concurrent diseases and pregnancy. Therefore, we aimed to investigate the patterns and causes of DMD change in patients with MS (PwMS) in Tehran, Iran. The understanding will help us identify opportunities to improve adherence and ultimately patient outcomes and health system efficiency through effective education, and recognition of more tolerable or simpler regimens. The aim of this study is to identify rate and pattern of DMDs among PwMS in Tehran. Material(s) and Method(s): The study population of this cross-sectional was all PwMS in Tehran province who had changed their DMD for any reason in the last 5 years until June 2, 2022. The basic information was extracted through nationwide MS registry of Iran (NMSRI), Tehran, where all MS data including diagnosis had been confirmed by trained neurologists based on the 2017 revisions of the McDonald criteria. Moreover, supplementary unregistered data were gathered through telephone follow-ups carried out by 6 trained physicians with precise quality checks. The questionnaires covered 5 aspects of MS including demographics, disease history, diagnosis, progress and treatment. DMDs were classified into 10 general classes. All participants were asked to attribute the change to distinct categories following a written pre-existing consent. IBM SPSS (version 23) was used for statistical analysis. All the steps taken were in complete adherence with the tenets of the declaration of Helsinki. Result(s): Among 1999 enrolled patients with a mean age of 36.9+/-9.4 and total disease duration of 7.06+/-5.8 years, 1315 experienced change (Group 1) during study period, while 684 did not (Group 2). There was no difference in terms of demographic characteristics between the two groups. On the other hand, Group 1 had longer disease durations and more comorbidities (P <0.001). Getting infected with COVID-19 more than 4 times was observed to be significantly higher in Group 1 (P =0.032). Unlike Patients with PPMS and RRMS, SPMS patients showed higher EDSS scores when experiencing no DMD change. The most widely used DMDs were interferons, while ocrelizumab was the least used drug. Corona virus had the most effect on the change of ocrelizumab. Conclusion(s): DMD change generally occurs independent of socioeconomic level. Since most of the patients (65.8%) experienced DMD change, which serves as the biggest cost component in PwMS, the economic aspects of MS management in this field should be considered in the future.Copyright © 2022
ABSTRACT
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. Method(s): 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. Result(s): 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(s): 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.Copyright © 2021 Iranian Neurological Association, and Tehran University of Medical Sciences Published by Tehran University of Medical Sciences.

ABSTRACT
Background: It is currently recommended to vaccinate against SARS CoV-2 for people with multiple sclerosis (MS), but it is uncertain what effect it will have on people with MS (PwMS). Objectives: We aimed to compare the side effects of the first and second doses of the Sinopharm vaccine in PwMS. Materials & Methods: This descriptive-analytical follow-up study was conducted on PwMS patients in Kermanshah province, Iran, who received the Sinopharm vaccine using the nationwide MS registry of Iran (NMSRI) by available methods between May and August 2021. Using a researcher-made questionnaire, demographic and clinical information about PwMS, as well as side effects from the Sinopharm vaccine were collected by telephone 5-14 days after the first and second doses. Data were analyzed using SPSS software version 25. Results: Study participants included 188 PwMS, including 148 females (78.7%) and 40 males (21.3%). PwMS had Median age of 42.66±11.1 years and Median 9.57±7.0 for disease duration. In the 1st dose, the prevalence of side effects was significantly higher than in the second dose (58.5% vs 47.0%, P=0.012). Fatigue (30.1%), myalgia (29.8%), fever (25.0%), and headache (22.3%) were the most common in the first dose, and fatigue (27.1%), headache (18.6%), myalgia (17.5%) and fever (14.9%) were the most common in the second dose. COVID-19 was present in 51 people (27.3%) before vaccination. Conclusion: Sinopharm vaccine side effects were significantly more prevalent in the first dose than in the second dose. Most side effects are moderate in severity and transient. © 2018 The Authors. This is an open access article under the CC-By-NC license.

ABSTRACT
Background: Recent Covid-19 outbreak around the world turned into an international public health concern. Generally, people who receives immunosuppressive treatments or have an underlying disease are more likely to be infected. Multiple sclerosis (MS) patients also may have higher risk of infection due to the taking immunosuppressive or immunomodulatory drugs. Our objectives were to identify the epidemiological characteristics of Covid-19 in patients with MS for improve quality of care and achievement to better diagnosis and treatment in MS patients in Iran. Material(s) and Method(s): The present data were obtained from a hospital-based registry in Imam Khomeini hospital, Tehran, Iran. Totally, 88 MS patients who was infected by Covid-19 were registered from May, 2020 to March 2021. Demographic and clinical data was collected (2). Result(s): 55 (65.5%) of participants were female by the mean age (SD) of 37.48 ± 10.05 years. Covid-19 diagnosis of 4 (4.5%) of patients was based on positive PCR test. The most MS treatment was receiving by patients was Rituximab (20 (22.7%)) following by Dimethyl Fumarate (14 (15.9%)), Fingolimod (10 (11.4%)), Glatiramer acetate (8 (9.1%)), Interferon β-1a (IM) (5 (5.7%)), Interferon β-1a (SQ) (5 (5.7%)), Interferon β-1b (3 (3.4%)), Triflunomide (2 (2.3%)) and Natalizumab (1 (1.1%)). The mean (SD) interval from the last Rituximab injection to Covid-19 infection was 3.80 ± 3.40 months. 37 (42.0%) MS patients continued to take their drugs after Covid-19 infection, while 10 (11.4%) of them stopped taking MS medicine and 7 (8.0%) of them was taking no treatment for controlling MS. 2 (2.3%) of participants was diagnosed by MS after Covid-19 infection. 9 (9.7%) subjects hospitalized due to Covid-19 infection. The mean (SD) duration of hospitalization was 5 ± 7.81 days. One (1.1%) death cases was reported. Conclusion(s): Our findings revealed valuable data of Covid-19 characteristics in patients with MS which could be useful for improving health services for MS patients during the Covid-19 pandemic (3-4).

ABSTRACT
Introduction: Iran is one of the countries with high prevalence of multiple sclerosis (MS) and COVID-19 infection. 2,691,352 patients with COVID- 19 have been identified including 75,568 deaths in Iran until May 12, 2021. Objectives: To determine Epidemiology and the risk of COVID- 19 infection among MS patients in Iran. Methods: The nationwide MS registry of Iran (NMSRI) has set up a COVID-19 infection program in 9 provinces of Iran in 2020. All MS cases with confirmed diagnosis of Covid-19 infection were registered in NMSRI. This system, registering baseline characteristics, clinical presentations and symptoms, diagnostic and treatments, hospital course and outcomes, identification the risk factors that develop Covid-19 infection and improving quality of care among MS patients in regional and national level. The neurologist registers new events into the dataset including demographic characteristics, definite diagnosis of COVID-19 and its symptoms, history of comorbidities, history of hospitalization, Changes in MRI and infection outcomes. Results: A total number of 408 MS cases including 320 (78.4%) females and 88 (21.6%) males enrolled in the study. The majority of subjects 299 (73.3%) had relapsing remitting MS. The mean (SD) of EDSS score was 1.88 (1.80) and 1.91 (1.92) before and after Covid-19 infection respectively (p value ≥0.05). Most common symptoms of infection included body aches 246 (60.3%), weakness and lethargy 242 (59.3%), fever 222 (54.4%), loss of sense of taste 206 (50.5%) and dry cough 167 (40.9%) respectively. The most common comorbidity was diabetes among 15 (3.7%) cases. Totally 77 (16.04%) cases were hospitalized and 4 (1%) were died. Conclusions: This study will provide valuable and novel epidemiological knowledge on Iranian MS patients with COVID-19. COVID-19 infection was more common among female and increased EDSS among subjects. The infection symptoms and mortality rate of COVID-19 in MS subjects are comparable to the general population.
