Women and multiple sclerosis: From gender medicine to precision medicine
No full textSex-based differences in multiple sclerosis (MS) are evident in various aspects of the disease, including biological processes, clinical presentation, MRI findings, and disease outcomes. The emerging field of precision medicine offers a promising approach to addressing the complexity of MS. By leveraging genetic markers, biomarkers, and other biological factors, precision medicine aims to tailor treatments to individual patients. However, the potential impact of sex and gender on treatment outcomes remains largely unexplored. Here, we examine how the two sexes/genders differ in MS, what evidence supports these differences, and how we can capture and utilize these differences to improve disease management. Additionally, we discuss the importance of promoting personalized medicine by incorporating gender medicine into comprehensive healthcare strategies

An overview of the efficacy and safety of ozanimod for the treatment of relapsing multiple sclerosis
Full text linkMultiple sclerosis (MS) is a complex disease of the central nervous system that can cause permanent disability in young adults. A large armamentarium is available for its management and is increasing over time. Ozanimod is an oral drug belonging to the sphingosine-1-phosphate receptor (S1PR) modulator family recently approved in different countries for MS with active disease. It selectively modulates S1PR1 and S1PR5 to prevent autoreactive lymphocytes from entering the central nervous system (CNS), where they can determine inflammation and neurodegeneration. Ozanimod was tested in one Phase II and two Phase III pivotal trials and was shown to be effective and well tolerated. Moreover, further investigations, including comparative trials with other S1P modulators and MS disease-modifying drugs, are needed to better define placement in MS treatment. Furthermore, ozanimod is currently under evaluation for inflammatory bowel diseases, such as ulcerative colitis and Crohn’s disease, in international phase III studies. This article retraces the itinerary leading to the approval of ozanimod for MS treatment and its peculiarities and potentiality inside the S1PR modulator family
Disease-modifying therapy for multiple sclerosis: Implications for gut microbiota
No full textBackground: Growing evidence has suggested the involvement of gut microbiota in the pathophysiology of multiple sclerosis (MS). Disease-modifying therapies (DMTs) exert a parallel effect on the gut microenvironment with subsequent modulation of the intestinal and systemic immune system. Herein, we summarize the current literature on the effect of DMTs on the gut microbiome and possible implications for MS. Methods: All the literature available in PubMed on the effects of DMTs on the gut microbiota composition in patients with MS was reviewed. We used multiple combinations of the following keywords: “multiple sclerosis; demyelinating disease; gut microbiome; microbiome; brain-gut axis; diet; fecal microbiome; disease modifying therapy; immunomodulator; interferon; glatiramer acetate; teriflunomide; dimethyl fumarate; natalizumab; alemtuzumab; anti-CD20; fingolimod”. All the original research articles available in English were included in this narrative review. Results: Ten original full-text articles were considered eligible, including seven case-control and three cohort studies. First-line DMTs, including oral and subcutaneous treatments (dimethyl fumarate, glatiramer acetate, and interferon β 1b) were considered, while a small number of patients with MS were under natalizumab, fingolimod and anti-CD20 treatments. Conclusions: Emerging evidence reported changes in the gut microbiome during exposition to DMTs. However, the association between DMTs exposure and microbial changes was mostly indirect, and the results of the different studies needed to be more consistent. The mitigation of methodological bias is necessary for future studies to allow the identification of a “microbial signature” related to MS pathophysiology, the role of DMTs, and possible prognostic implications
