A large study that reviewed longitudinally collected data from the national Swedish Patient Register found that head trauma in adolescents was associated with an increased risk of subsequent diagnosis of multiple sclerosis.
In this MRI and histopathological study, the investigators showed that cortical T1w/T2w ratio was unrelated to myelin density, but had a strong correlation with dendritic density. Furthermore, abnormal values within the posterior cingulate cortex correlated with impairment in cognitive domains.
A review of patients with relapsing-remitting multiple sclerosis who discontinued fingolimod therapy showed that five out of 46 (10.9 %) of these patients developed a rebound phenomenon between 4 to 16 weeks, where disease activity returns and often exceeds pre-treatment levels.
A study of intrathecal immune markers in neuro-immunological diseases revealed increased numbers of activated T and B cells in both relapsing and progressive multiple sclerosis, but they were preferentially embedded in the brain tissue in progressive multiple sclerosis.
Interim analysis at 3 years post-treatment of a study of high-dose immunosuppression and autologous hematopoietic stem cell transplant for relapsing remitting-multiple sclerosis demonstrates sustained disease control but also shows potential risks associated with this treatment.
