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: Multiple sclerosis (MS) is a chronic central nervous system disease, and primary progressive multiple sclerosis (PPMS) is one the main types of MS, which has unknown environmental risk factors. The present study was conducted with the aim to identify the association of waterpipe and cigarette smoking, substance abuse, and alcohol consumption with the risk of PPMS development.Methods: A population-based, case-control study was conducted in Tehran, Iran, on 146 PPMS cases and 294 controls. PPMS cases were diagnosed and confirmed by neurologists. Standard random digit dialing was used to select sex-matched healthy control participants from the same source population as the cases. Logistic regression analysis was used to estimate unadjusted and adjusted odds ratios (OR).Results: In total, 440 subjects participated in the study. PPMS was associated with ever smoking cigarettes [OR = 2.48; confidence interval (CI) = 1.44-4.27], and passive smoking (OR = 2.20; CI = 1.34-3.62). However, having ever smoked waterpipe was not significantly associated with PPMS risk (OR = 1.19; CI = 0.62-2.26). Those who had all 3 types of smoking had an accumulative OR that was 10.45 times higher than that in individuals without any type of smoking (OR: 10.45; 95% CI = 3.5-31.2). We did not find any significant association between PPMS risk and substance abuse and alcohol consumption.Conclusion: Cigarette smoking and being exposed to passive smoking are important risk factors for developing PPMS; in addition, the use of 3 types of smoking, showed an OR higher than that in those without any smoking. Considering the global increase in tobacco smoking, this finding emphasizes the importance of interventional programs for the prevention of tobacco smoking.

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: 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: 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.

Background: The environmental factors play a role as risk factors of multiple sclerosis (MS). This study aimed at gathering environmental risk factors of MS in the Middle East and North Africa (MENA). Methods: We used MEDLINE and EMBASE databases by a systematic review method. Out of a total of 123 studies, 16 studies met the eligibility criteria. Results: Totally, 47 risk factors were assessed as follows: six studies found sunlight exposure as a protective factor with the odds ratio (OR) ranging from 0.06 to 0.57. Six studies evaluated smoking as a risk factor with the OR ranging from 1.69 in all patients to 6.48 in female patients. Four studies supported measles infection as a risk factor with the OR ranging from 1.60 to 3.77, and in 3 studies, stressful events had a significant association with the OR of 1.80, 1.90, and 32.57. Conclusion: Among 47 assessed risk factors, sunlight exposure, cigarette smoking, measles infection, Epstein-Barr virus (EBV) infection, and stressful events had a significant association with MS.

Background: The association betweenmedical history and primary progressive multiple sclerosis (PPMS) development has not been well documented in the pertinent literature.The possible association between 23 medical diseases and PPMS occurrence was assessed in the present study. Methods: In order to figure out the possible association between several medical histories and PPMS occurrence, the present population-based case-control study examined 143 PPMS cases in Tehran, Iran, from 2019 to 2020. Diagnosis of PPMS was confirmed by neurologists based on the 2017 McDonald criteria. Sex-matched healthy controls (n = 143) were selected using the random-digit dialing (RDD) technique. Face-to-face and telephone interviews were conducted for gathering the data. The conditional logistic regression model was used to calculate adjusted and unadjusted odds ratio (OR) at a 95% confidence interval (CI). Results: A significant association was found between PPMS development and diseases like depression (OR = 3.12, 95% CI: 1.49-6.53), migraine (OR = 0.19, 95% CI: 0.05-0.67), infectious mononucleosis (OR = 13.16, 95% CI: 2.74-63.17), hypothyroidism (OR = 3.20, 95% CI: 1.23-8.30), and kidney failure (OR = 3.76, 95% CI: 1.41-9.99). Conclusion: Lifetime history of depression, infectious mononucleosis, hypothyroidism, and kidney failure might increase the risk of PPMS development, while individuals with positive history of migraine disease are at lower risk for developing PPMS.

Background: After intensified economic sanctions against Iran, decreased welfare of patients were more recognizable. The present study was aimed at identifying the challenges and stress level experienced by patients with multiple sclerosis (MS) regarding treatment and health care services in 2018-2019 after strengthening of economic sanctions against Iran. Methods: A cross-sectional study was conducted on MS patients in Tehran, Iran. A structured questionnaire was designed to measure the main variables addressing the challenges and stress level of MS patients with respect to receiving care and treatment services. Results: In total, 1039 MS patients were enrolled into the study. Among the patients who answered yes to the selected questions, 873 (85.8%) and 837 (86%) were concerned about medicine unavailability and supply and purchase of internationally branded medicine, respectively. Moreover, 671 (70.3%) subjects were concerned about replacing their medicines with cheaper alternatives due to financial problems and 427 (41.4%) were unwilling to continue their treatment due to the economic burden of MS. In total, 795 (82%) were concerned about the effectiveness of Iranian drugs in comparison with internationally branded drugs. Generally, 970 (93.53%) subjects had experienced increased current living costs and 711 had experienced (68.82%) reduced nutrition quality, which (OR: 2.68; 95% CI: 1.99, 3.60) was significantly higher among subjects who had an income of less than or equal to 250 US$ per month Conclusion: The sanctions can impose greater stress and hardship on patients due to the unavailability and costs of medicines. Iran should manage health care quality and provide services to prevent the adverse effects of sanctions on MS patients and guarantee patients’ right to receive well-established medication and health services.

Background: Neuromyelitis optica spectrum disorder (NMOSD) is a neuroinflammatory demyelinating disease caused by the presence of a highly specific serum autoantibody marker, NMO-immunoglobulin G (NMO-IgG), that reacts against the water channel aquaporin-4 (AQP4). The present study examined the association between NMO-IgG sero-positivity and environmental factors such as cigarette smoking.
Methods: A cross-sectional study was conducted in Sina Hospital, a tertiary referral center in Tehran, Iran. All the patients with a definite diagnosis of NMOSD were involved in this study. The enzyme-linked immunosorbent assay (ELISA) was used to examine the AQP4-IgG status. To assess the association between NMO-IgG sero-positivity and cigarette smoking, a researcher-made questionnaire covering patients’ lifestyle information on smoking habits was designed and administered using the structured face-to-face interviews with the patients.
Results: The positive and negative NMO-IgG results were found in 44 (46.8%) and 50 (53.2%) patients, respectively. The increased NMO-IgG sero-positivity odds were observed among the lifetime smokers [odds ratio (OR) = 3.24, 95% confidence interval (CI): 1.16-9.08], current smokers (OR = 6.08, 95% CI: 1.26-29.39), and passive smokers (OR = 2.22, 95% CI: 1.10-4.50).
Conclusion: Lifetime and current smoking as well as passive smoking can be regarded as risk factors for NMO-IgG sero-positivity. Smoking with its immunological effects can lead to the production of autoantibodies such as NMO-IgG.
