Background: Hormonal variations are known to influence the course of multiple sclerosis (MS). Objectives: We aimed to evaluate the impact of menopause in MS course, including disease activity and disability progression. Methods: We conducted a retrospective longitudinal cohort study including all women, older than 44, post-menopausal, with a diagnosis of MS at least 1 year before menopause. We evaluated the impact of menopause in MS course comparing clinical and radiologic outcomes within 5 years before and after menopause. We repeated the analysis in subgroups of patients without disease-modifying treatment (DMT) change or co-morbidities diagnosed during the observation period, considering that those factors might also impact MS outcomes. Results: Thirty-seven women, with a mean age at the time of menopause of 49.8 (±4.06) years were included in the analysis. Within 5 years following menopause, we observed a decrease in the annualized relapse rate (0.37 ± 0.35 pre-menopause vs. 0.08 ± 0.18 post-menopause, p < 0.001) compared with the same period before menopause, while the EDSS progression rate remained stable (0.13 ± 0.24 EDSS point/year pre-menopausal vs. 0.13 ± 0.18 post-menopause, p = 0.935). EDSS progression events frequency was similar before and after the menopause (37.8 vs. 48.6%, respectively, p = 0.424). These observations persisted in patients’ subgroups without DMT switch or co-morbidities. Conclusions: Following menopause, we observed a reduction in the relapse rate, but the disability progression continued at a similar rate, compared to the pre-menopausal period. These observations persisted in the subgroup of patients without changes in DMT or co-morbidities diagnosed during the observation period.

Over the recent years, the treatment of multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) has evolved very rapidly and a large number of disease-modifying treatments (DMTs) are now available. However, most DMTs are associated with adverse events, the most frequent of which being infections. Consideration of all DMT-associated risks facilitates development of risk mitigation strategies. An international focused workshop with expert-led discussions was sponsored by the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) and was held in April 2021 to review our current knowledge about the risk of infections associated with the use of DMTs for people with MS and NMOSD and corresponding risk mitigation strategies. The workshop addressed DMT-associated infections in specific populations, such as children and pregnant women with MS, or people with MS who have other comorbidities or live in regions with an exceptionally high infection burden. Finally, we reviewed the topic of DMT-associated infectious risks in the context of the current SARS-CoV-2 pandemic. Herein, we summarize available evidence and identify gaps in knowledge which justify further research.

Background: Tetrabenazine (TBZ) is commonly used in hyperkinetic movement disorders. In this retrospective study, we aimed to assess the TBZ effectiveness and adverse events (AEs) in Huntington disease (HD), vascular chorea, tics, dystonia, tardive oromandibular (OM) dyskinesia and other tardive syndromes (TS). Methods: Qualitative analysis of clinical response was used to estimate TBZ effectiveness. TBZ-associated AE frequency and subsequent discontinuation rate were used to estimate tolerability; the tolerability profile was measured through the TBZ minimal dose and exposure time required to elicit AEs. Results: Of 108 included patients, 87% had a clinically meaningful improvement sustained over a period of 40 months. TBZ-responder rate ranged from 100% in HD to 62.5% and 77.1% in tic disorders and OM dyskinesia, respectively (p < 0.001). TBZ-associated AE frequency ranged from 40.9% in other TS and 41.7% in vascular chorea and HD, to 60% in OM dyskinesia (p < 0.001). The most common AEs were Parkinsonism (51.8%) and psychiatric disorders (25%). The 'other AEs' category (mainly somnolence) presented the shortest minimal exposure time (3 months). AE-eliciting dose differed from 18.8 mg and 25 mg in tics and tardive disorders, to 75 mg in HD (p = 0.003). Patients with AEs were tendentiously older at TBZ initiation (p = 0.022). Conclusions: TBZ proved an effective and relatively well tolerated treatment in hyperkinetic disorders, with excellent results in HD. AEs were more common in OM dyskinesia, which may be related to higher age at TBZ initiation. TBZ-associated somnolence and Parkinsonism were more frequent during the titration and maintenance periods, respectively.
