The objective of this study was to determine the immune responses to candidate viral triggers of multiple sclerosis in patients and healthy siblings raised in the same family household. Virus antigen-specific IgG responses to Epstein-Barr virus-derived gene products as well as to human herpersvirus-6, human cytomegalovirus, and measles virus were evaluated in 25 multiple sclerosis patients and compared with 49 healthy full-siblings. IgG responses to the latent Epstein-Barr virus-encoded nuclear antigen-1 (EBNA1) were selectively increased in individuals with multiple sclerosis compared with their unaffected siblings. We conclude that elevated IgG responses towards EBNA1 are associated with the development of multiple sclerosis.

Background And Objectives: Peripartum mood and anxiety disorders constitute the most frequent form of maternal morbidity in the general population, but little is known about peripartum mental illness in mothers with multiple sclerosis (MS). We compared the incidence and prevalence of peripartum mental illness among mothers with MS, epilepsy, inflammatory bowel disease (IBD), and diabetes and women without these conditions.
Methods: Using linked population-based administrative health data from ON, Canada, we conducted a cohort study of mothers with MS, epilepsy, IBD, and diabetes and without these diseases (comparators) who had a live birth with index dates, defined as 1 year before conception, between 2002 and 2017.

To examine the effects of self-paced combined high-intensity interval training and resistance training (HIIT-RT) on oxidative stress, inflammation lipid profile and body composition in people with multiple sclerosis (PwMS). Twenty-three PwMS were randomly assigned to either a control group (CG, n = 12) or a training group (TG, n = 11). The TG performed a 12-week self-paced HIIT-RT (3 times/week).

Optic neuritis (ON) is the inflammation of the optic nerve. 'Typical' ON is commonly associated with multiple sclerosis (MS) and its classic triad includes sudden loss of vision, pain with eye movement and dyschromatopsia. It usually has good visual outcome irrespective of treatment.
