Abstract
Background: The onset of primary progressive multiple sclerosis (PPMS) can be triggered by sun exposure and physical activity. The present study aimed to determine the risk of sun exposure and physical activity in PPMS development.
Methods: The case-control study recruited PPMS cases and healthy controls from the general population from September 2019 to September 2020 in Tehran, Iran. The selection of sex-matched controls from the same source population of cases was performed. Sun exposure was assessed in terms of exposure time in two age groups of 13-19 years and over 20 years in winter and summer.
Results: This study examined 146 PPMS cases and 294 controls. The sun exposure in summer in the age group 13-19 was negatively associated with the incidence of the disease (OR=0.68 (CI=0.57-0.82)). This relationship was also observed in the groups of men (OR=0.55 (CI=0.40-0.74)) and women (OR=0.70 (CI=0.53-0.91)). Exposure to sunlight in winter in the age group 13-19 was negatively associated with the incidence of the disease (OR=0.28 (CI=0.19-0.42)). In the group over 20 years, sun exposure was negatively associated with disease incidence in summer (OR=0.49 (CI=0.36-0.66)). Exposure to sunlight on average in winter in the age group over 20 years was negatively associated with the incidence of the disease (OR=0.14 (CI=0.07-0.28)) which in the male group OR=0.12 (0.04-0.32)) and women (OR=0.06 (CI=0.02-0.21)) were seen. Regarding physical activity, only physical activity above 4000 MET per week in the group of women was negatively associated with the incidence of the disease (OR=5.30 (CI=1.05-26.59), but in other groups, this negative relationship was not observed.
Conclusion: Exposure to sunlight in winter and summer had a negative relationship with the incidence of the disease. Physical activity was only negatively associated with the incidence of the disease in very high doses and women.

Volume 80, Issue 6 (September 2022)
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.
Methods: 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.
Results: 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: 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.
