Assessment of Bone Mineral Density Over 1 Year in a Cross-Sectional Cohort of Migraine Patients Receiving Anti-CGRP Monoclonal Antibodies.

BACKGROUND: Calcitonin gene-related peptide (CGRP), implicated in migraine pain, also possesses bone anabolic properties, which leads to the possibility that monoclonal antibodies targeting CGRP (anti-CGRPs) might increase the risk of bone density abnormalities. OBJECTIVE: The objective of this study was to explore bone mineral density abnormalities in a cohort of migraine patients treated with anti-CGRPs. METHODS: This was a single-center, cross-sectional, cohort study including migraine patients who underwent a densitometry assessment during anti-CGRP treatment. We assessed the frequency of osteopenia or osteoporosis (OSTEO+ status), defined as a bone mineral density T-score of -1 to -2.5, and <-2.5 standard deviations from the young female adult mean, respectively. Additionally, the association of OSTEO+ status with anti-CGRP treatment duration and primary osteoporosis' risk factors was investigated using logistic regression models. RESULTS: Data from 51 patients (43 female, mean age 46 ± 13.9 years) were evaluated. The mean duration of anti-CGRP treatment was 15.7 (±11.8) months. Twenty-seven patients (53%) were OSTEO+ (n = 22 osteopenia; n = 5 osteoporosis). In the final model, menopause [odds ratio 11.641 (95% confidence interval 1.486-91.197), p = 0.019] and anti-seizure drug use [odds ratio 12.825 (95% confidence interval 1.162-141.569), p = 0.037] were associated with OSTEO+ status. CONCLUSIONS: In our cohort of migraine patients, no evidence of an association between anti-CGRP treatment duration and an increasing risk of bone mineral density abnormalities was found. However, these findings are preliminary and necessitate further longitudinal research with larger cohorts and extended follow-up to be validated.

Persistent longitudinal T cell responses after SARS-CoV-2 mRNA vaccines in MS patients on different disease modifying treatments.

Few data are available regarding vaccine induced SARS-CoV-2 specific T cell responses over time and after booster doses in multiple sclerosis (MS) patients on different disease modifying treatments. We measured SARS-CoV-2 specific CD4+ T cell responses in 72 samples collected from 36 MS patients. The percentage of CD4+ CTVlow CD25+ ICOS+ T cells after stimulation with Spike Recombinant Protein was 29.9 (17.0-43.6) on teriflunomide, 32.4 (11.9-42.5) on ocrelizumab, but much lower (0.6 [0.3-5.9]) on sphingosine-1-phospate receptor modulators (ß = -26.35, p = 0.003). SARS-CoV-2 specific T cells were mainly of Th1 type and stable over time and after booster vaccine doses. mRNA vaccines elicit strong and persistent CD4+ T cell responses against SARS-CoV-2 in MS patients on anti-CD20 and teriflunomide, but not in those on sphingosine-1-phospate receptor modulators.

Impact of multiple sclerosis comorbidities on quality of life and job activity.

BACKGROUND: Multiple sclerosis (MS) is frequently accompanied by comorbid conditions. OBJECTIVES: This study aimed to determine the prevalence of key comorbid conditions in people with multiple sclerosis (pwMS) and assess their impact on quality of life and work-related activities. METHODS: A cross-sectional study involving 755 pwMS from two third-level Italian MS centers was conducted. Comorbidities were identified from medical records, and quality of life was assessed using the EQ-5D-3L questionnaire. Work-related challenges were evaluated using the Multiple Sclerosis Questionnaire for Job Difficulties (MSQ-Job). RESULTS: 53.8% of pwMS had at least one comorbidity. Hypertension, depression, and anxiety were the most prevalent. Comorbidity presence was associated with reduced quality of life scores in almost all EQ-5D-3L domains and greater job difficulties in all but one MSQ-Job domain. CONCLUSION: Comorbidities in pwMS are prevalent and have a profound influence on quality of life and work-related activities. This comprehensive study offers new insights into the role of comorbidities in MS within the Italian context, emphasizing the need for a multidisciplinary approach in MS management. Further research is crucial to deepen our understanding of these findings in the broader Italian MS community.

Tolerability and Acceptance of Switching from Brand to Generic Glatiramer Acetate in Multiple Sclerosis.

Background: The costs of disease-modifying therapies (DMTs) for multiple sclerosis (MS) have increased interest in generic alternatives. Methods: This prospective and observational study aims to investigate the safety, tolerability, and acceptance of switching from brand glatiramer acetate (GA) 40 mg/mL three times per week (Copaxone®) to generic GA 40 mg/mL three times per week (Glatiramyl®). Conducted at the Neurocenter of Southern Switzerland from September 2020 to September 2021, the study enrolled 27 patients; 21 completed the study. Participants reported on local and systemic side effects three months before and after the switch, and on switch acceptance by means of visual analogue scales (from 0 to 10). Results: Results indicated that those on generic GA experienced fewer local (81.0% vs. 96.3%) and systemic (33.3% vs. 59.3%) adverse events than with the brand drug. The median intensity of local adverse events was 8 (4-20) on generic GA vs. 16 (9-22) on brand GA, while the median intensity of systemic adverse events was similar between generic and brand GA [0 (0-27) vs. 0 (0-21.5), respectively]. Seventy-one percent of participants rated their acceptance of generic GA as 7/10 or higher. Conclusions: The results suggest that switching from brand to generic GA 40 mg/mL is safe, well-tolerated, and accepted by patients with MS.

Early prediction of unfavorable evolution after a first clinical episode suggestive of multiple sclerosis: the EUMUS score.

BACKGROUND: Predicting disease progression in patients with the first clinical episode suggestive of multiple sclerosis (MS) is crucial for personalized therapeutic approaches. This study aimed to develop the EUMUS score for accurately estimating the risk of early evidence of disease activity and progression (EDA). METHODS: Retrospective analysis was conducted on data from 221 patients with a first clinical MS episode collected from four Italian MS centers. Various variables including socio-demographics, clinical features, cerebrospinal fluid analysis, evoked potentials, and brain MRI were considered. A prognostic multivariate regression model was identified to develop the EUMUS score. The optimal cutoff for predicting the transition from no evidence of disease activity (NEDA3) to EDA was determined. The accuracy of the prognostic model and score were tested in a separate UK MS cohort. RESULTS: After 12 months, 61.54% of patients experienced relapses and/or new MRI lesions. Younger age (OR 0.96, CI 0.93-0.99; p = 0.005), MRI infratentorial lesion(s) at baseline (OR 2.21, CI 1.27-3.87; p = 0.005), positive oligoclonal bands (OR 2.89, CI 1.47-5.69; p = 0.002), and abnormal lower limb somatosensory-evoked potentials (OR 2.77, CI 1.41-5.42; p = 0.003) were significantly associated with increased risk of EDA. The EUMUS score demonstrated good specificity (72%) and correctly classified 80% of patients with EDA in the independent UK cohort. CONCLUSIONS: The EUMUS score is a simple and useful tool for predicting MS evolution within 12 months of the first clinical episode. It has the potential to guide personalized therapeutic approaches and aid in clinical decision-making.
