People with multiple sclerosis (pwMS) have a high risk of frailty. We aim to evaluate frailty using the Tilburg frailty indicator (TFI), a multidimensional self-reported questionnaire, and to explore its relationship with autonomy, quality of life (QoL), and disability. All the patients with MS enrolled completed TFI (frail when TFI score ≥ 5 points), the Groningen Activities Restriction Scale to evaluate autonomy, and the Multiple Sclerosis Impact Scale-29 to evaluate QoL. We collected the Expanded Disability Status Scale (EDSS) score, age and gender. Data were analysed using descriptive analyses, hierarchical multiple regression, and ANCOVA. A total of 208 pwMS (mean age 44 years, SD=11; 75% women; 89.4% relapsing-remitting) were enrolled. The mean TFI total score was 5.7 points (SD=3.0; range 0–14), with the 62.5% of participants exhibiting frailty. After controlling for age and gender, the EDSS score was associated with the total (β=0.469; R2=0.255; p <0.001) and the physical (β=0.571; R2=0.349; p <0.001) frailty score, with an explained variance of 25.5% and 34.9%, respectively. No relationships between the EDSS and psychological and social frailty domains were detected. The proportion of frail patients with EDSS ≥ 6.0, EDSS within 3.5–5.5, and EDSS ≤ 3.0 was 91.7%, 83.3%, and 66.0%, respectively. Frail patients exhibited higher autonomy impairment (p = 0.017) and worse QoL (p <0.001). We found a high frequency of frail patients with MS. Frailty is more common in patients with higher disability, but it affects also those with low EDSS. In people with MS frailty could be influenced by factors other than disability.

Highlights • Vascular comorbidities are very common in general population as in MS patients. • Our results indicated vascular comorbidities as negative prognostic factors for brain atrophy. • These conditions should be carefully monitored in patients with MS with a focus on limiting brain damage. Abstract Background Some studies have indicated the importance of considering the presence of vascular comorbidities as negative prognostic factors for MRI outcomes in multiple sclerosis (MS). This study aimed to evaluate the possible influence of the most frequent vascular risk factors on brain volume in MS, also exploring the burden of their combined effects. Methods MS patients with at least one vascular risk factor and a control group of MS patients were enrolled. Patients underwent brain MRI and the volumes of the whole brain (WB), white matter (WM), grey matter (GM), and cortical GM were estimated by SIENAX. Longitudinal atrophy was assessed by SIENA. Results The sample included 326 MS patients, of these 49 (15%) had diabetes mellitus, 44 (13.4%) hypertension and 50 (15.3%) were active smokers. Multiple regression analyses revealed that diabetes mellitus was associated with significant reductions in WB (p = 0.03), GM and cortical GM (p = 0.01) volumes. Similarly, reduced cortical GM volume was associated with hypertension (p < 0.05). A strong relationship between the co-occurrence of multiple vascular risk factors and lower cortical GM volume (p = 0.007) was also identified. Ninety patients were included in the longitudinal study and a greater annualized brain volume loss was found in those with at least one vascular risk factor than in the control group (−1.05% vs. −0.58%, p = 0.005). Conclusions Our results show that the vascular comorbidities affect brain atrophy, indicating that these conditions should be carefully monitored in patients with MS with a focus on limiting brain damage.

• In the current therapeutic scenario, new drugs are available for patients with progressively active MS. • The review critically analyzes the current measures to assess treatment response in progressive MS. • The impact of age and comorbidities on the assessment of MS outcomes is also examined. • A more comprehensive and patient-centered approach to evaluating DMT efficacy is discussed. New treatment options are available for active progressive multiple sclerosis (MS), including primary and secondary progressive forms. Several pieces of evidence have recently suggested a "window of beneficial treatment opportunities," principally in the early stages of progression. However, for progressive MS, which is characterised by an inevitable tendency to get worse, it is crucial to redefine the "response to treatment" beyond the concept of "no evidence of disease activity" (NEDA-3), which was initially conceived to evaluate disease outcomes in relapsing-remitting form, albeit it is currently applied to all MS cases in clinical practice. This review examines the current perspectives and limitations in assessing the effectiveness of DMTs and disease outcomes in progressive MS, the current criteria applied in defining the response to DMTs, and the strengths and limitations of clinical scales and tools for evaluating MS evolution and patient perception. Additionally, the impact of age and comorbidities on the assessment of MS outcomes was examined. [ABSTRACT FROM AUTHOR]

Background Paediatric onset multiple sclerosis (POMS) is associated with reduced brain and deep grey matter volume in comparison with that in healthy controls and individuals with adult onset multiple sclerosis (AOMS). The aim of our study was to evaluate the impact of POMS on adult brain volume with adjustment for other parameters, such as disease duration. Patients and methods We recruited 20 POMS and 40 AOMS patients and 20 healthy controls matched for age and sex. All study participants were adults at the time of inclusion in the study. All study subjects underwent brain magnetic resonance imaging (MRI) to evaluate whole brain, white matter, grey matter, cortical, and deep grey matter volumes. Clinical features, such as the Expanded Disability Status Scale (EDSS) score and disease duration, were also assessed. Results Brain (p = 0.01), grey matter (p = 0.01), and deep grey matter volume (p = 0.03) was significantly lower in POMS patients than in AOMS patients, while no differences were detected in the volume of white matter or cortical grey matter. A multiple linear regression analysis showed a relationship between brain volume (dependent variable) and the independent variables age (p < 0.000) and paediatric onset (p < 0.001), while other independent variables, including disease duration, sex, and disability, were not significantly different among groups. There were significant differences in thalamic volume among POMS and AOMS patients and healthy controls. Conclusion Our data support the previous findings that POMS patients have reduced brain and deep grey matter volume, particularly thalamic volume, compared with sex- and age-matched AOMS patients and healthy controls. These findings appear to be independent of disease duration and other clinical features. [ABSTRACT FROM AUTHOR]

Background Oligoclonal bands of IgG (OB) are proposed as an early prognostic factor of the disease. Growing attention is directed towards brain volume evaluation as a possible marker of the severity of MS. Previous studies found that MS patients lacking OB have less brain atrophy. Aim to evaluate a possible relationship between OB and cerebral volume in a cohort of early MS patients. Methods Inclusion criteria were: diagnosis of relapsing-remitting MS; CSF analysis and MRI acquired simultaneously and within 12 months from clinical onset. A total of 15 healthy controls underwent MRI. Results In 20 MS patients, CSF analysis did not show OB synthesis (OB negative group). A control group of 25 MS patients in whom OB was detected was also randomly recruited (OB positive group). T test showed a significant difference in NWV between the OB positive and OB negative groups (P value = 0.01), and between the OB positive group and the healthy controls (P value = 0.001). No differences were detected between OB negative group and healthy controls. Multivariable linear regression showed a relationship between NWV and OB synthesis (P value = 0.02) controlling for age, gender, and EDSS. Conclusions Our preliminary results suggest that OB positive patients show more atrophy of white matter since early phases of the disease, supporting the role of CSF analysis as a prognostic factor in MS.

Background Notoriously the treatment of multiple sclerosis (MS) is based on the use of several different drugs, characterized by a diverse mechanism of action, efficacy and safety. Recently, progress has been made towards developing new oral immunotherapies, and dimethyl fumarate is the third oral agent approved for the treatment of relapsing-remitting forms. Case A 24-year-old patient, affected by relapsing remitting multiple sclerosis, started treatment in December 2014 with dimethyl fumarate. The common side effects (flushing and gastrointestinal events) of dimethyl fumarate occurred at the beginning of treatment, but resolved after 1 month. Six months later, the patient presented with serious recrudescence of the gastrointestinal event. In addition to this symptom, he had developed acute omphalitis–a very rare infection in adults. Conclusion The pathogenic role of dimethyl fumarate to induce this rare infection was probably related to changes in immunological surveillance as well as to the irritant effect of this agent on the gastrointestinal epithelium. Therefore, post-marketing studies in clinical practice are still needed to provide the necessary long-term safety data. [ABSTRACT FROM AUTHOR]

• We explored the relationship between event-related potentials, deep grey matter atrophy and cognition in MS. • Cortex volume emerged as the most significant predictor of the P300 amplitude. • The amygdala and hippocampal volumes were found to influence P300 latency. • The combination of structural MRI and neurophysiological techniques could improve the understanding of CI in MS. Event-related potentials (ERPs) have been proposed as a neurophysiological biomarker to capture cognitive dysfunction in multiple sclerosis (MS). Few studies have evaluated the relationships between ERPs and brain atrophy as known marker of structural brain damage related to cognitive impairment (CI). To explore the relationships of brain atrophy, including of the cortex and deep grey matter, with ERP abnormalities and cognitive function, as defined using the Brief Repeatable Battery of Neuropsychological Tests (BRBN). Seventy-eight patients with relapsing-remitting MS were enroled, of which 38 (48.7%) had CI. Independent t-test comparisons of the ERP parameters found a significant difference in P300 wave latency, with a latency of 343.7 ± 32.6 ms in the CI group vs. 320.3 ± 16.5 ms in the cognitively preserved (CP) group (p = 0.001). Significant differences in the MRI measurements, including the cortex (p = 0.02) and deep grey matter structures [thalamus (p = 0.001), amygdala (p = 0.030), and nucleus accumbens (p = 0.004)) were observed, with lower measurements in the CI group. Regression models were also performed to explore the impact of brain volumes on ERP parameters. This showed a relationship between P300 latency and the lower amygdala (p = 0.02) and hippocampus (p = 0.03) volumes, while the amplitude of the P300 was significantly associated with a lower cortex volume (p = 0.01). Cortex volume emerged as the most significant predictor of the P300 amplitude. The amygdala and hippocampal volumes were found to influence P300 latency, highlighting the role of deep grey matter atrophy in ERPs for the first time. The combination of structural MRI and neurophysiological techniques, sensitive to diverse aspects of MS pathology, could improve the understanding of CI in MS and its neurodegenerative and inflammatory substrate.

• Bipolar disorder (BD) is frequently observed in multiple sclerosis (MS). • Largely unexplored is the brain damage related to BD in MS. • We found smaller nucleus accumbens, putamen and pallidus in MS patients with BD. • Deep grey matter alterations may influence the BD occurrence in MS. Bipolar disorder (BD) is frequently observed in patients affected by multiple sclerosis (MS), presenting a lifetime estimate of around 8%. However, uncertainty exists on the brain damage associated with this psychiatric comorbidity. This study aimed to investigate the effect of brain atrophy, particularly that of the subcortical grey matter (scGM) structures that notoriously regulate the affective functioning, on the co-occurrence of BD in patients with MS. A group of patients with MS affected by BD and a control group of patients with MS without any mood/psychiatric disorder, as defined using standardised diagnostic tools (Advanced Neuropsychiatric Tools and Assessment Schedule), were recruited. The patients underwent brain MRI, and the volumes of the whole brain (WB), white matter (WM), and grey matter (GM) were estimated using SIENAX. Thus, the scGM volumes of the putamen, caudate, thalamus, hippocampus, amygdala, nucleus accumbens, and pallidus were estimated using the FIRST tool. The sample included 61 patients with MS, amongst whom 15 (24.6%) had BD. No differences in the WB, WM, and cortical GM volumes were observed between the patients with MS with and without BD. Conversely, the multiple regression analysis revealed a significant association of BD with lower volumes of the putamen (p = 0.032), nucleus accumbens (p = 0.029), and pallidus (p = 0.061; with a trend towards significance), independently from the demographic and MS clinical features. Our preliminary results indicated that the nucleus accumbens and putamen are smaller in MS patients with BD. Further investigations in larger cohorts of MS patients with affective disorders are necessary to confirm these data and understand the structural brain damage underlying this psychiatric comorbidity.
