Purpose: We performed a pharmacovigilance study of 10 drugs used in patients with relapsing-remitting multiple sclerosis (RR-MS). Our aim was to provide an overview of the safety of these drugs by the evaluation of reported expected and unexpected adverse reactions.
Patients And Methods: We collected and analyzed adverse drug reactions from RR-MS patients belonging to four hospitals in three Italian regions, for a period of 24 months.
Results: We received a total of 411 adverse reactions, of which 84.18% were expected and only 15.82% were unexpected. We found no correlation between the number of reported adverse reactions and the route of administration (injectable/intravenous drugs N=224, oral drugs N=187). However, oral agents have caused a greater number of unexpected moderate-to-severe adverse reactions while, in injectable and infusion therapies, they have been evaluated as mild-moderate adverse reactions.
Conclusion: Our results underscore the importance of monitoring the safety profile of multiple sclerosis therapies, with particular attention to oral agents that have been introduced later in the clinical practice.

Multiple sclerosis (MS) is a chronic autoimmune disorder marked by neuroinflammation, demyelination, and neuronal damage. Recent advancements highlight a novel interaction between iron-dependent cell death, known as ferroptosis, and gut microbiota, which may significantly influences the pathophysiology of MS. Ferroptosis, driven by lipid peroxidation and tightly linked to iron metabolism, is a pivotal contributor to the oxidative stress observed in MS.

The complicated neurological syndrome known as multiple sclerosis (MS) is typified by demyelination, inflammation, and neurodegeneration in the central nervous system (CNS). Managing this crippling illness requires an understanding of the complex interactions between neurophysiological systems, diagnostic techniques, and therapeutic methods. A complex series of processes, including immunological dysregulation, inflammation, and neurodegeneration, are involved in the pathogenesis of MS.

Objectives: We aim to investigate cognitive phenotype distribution and MRI correlates across pediatric-, elderly-, and adult-onset MS patients as a function of disease duration.
Methods: In this cross-sectional study, we enrolled 1262 MS patients and 238 healthy controls, with neurological and cognitive assessments. A subset of 222 MS patients and 92 controls underwent 3T-MRI scan for brain atrophy and lesion analysis.
