Resting-state functional connectivity in multiple sclerosis patients receiving nabiximols for spasticity.

BACKGROUND: Nabiximols (Sativex®) is a cannabinoid approved for multiple sclerosis (MS)-related spasticity. Its mechanism of action is partially understood, and efficacy is variable. OBJECTIVE: To conduct an exploratory analysis of brain networks connectivity changes on resting state (RS) functional MRI (fMRI) of MS patients treated with nabiximols. METHODS: We identified a group of MS patients treated with Sativex® at Verona University Hospital, who underwent RS brain fMRI in the 4 weeks before (T0) and 4-8 weeks after (T1) treatment start. Sativex® response was defined as ≥ 20% spasticity Numerical Rating Scale score reduction at T1 vs. T0. Connectivity changes on fMRI were compared between T0 and T1 in the whole group and according to response status. ROI-to-ROI and seed-to-voxel connectivity were evaluated. RESULTS: Twelve MS patients (7 males) were eligible for the study. Seven patients (58.3%) resulted Sativex® responders at T1. On fMRI analysis, Sativex® exposure was associated with global brain connectivity increase (particularly in responders), decreased connectivity of motor areas, and bidirectional connectivity changes of the left cerebellum with a number of cortical areas. CONCLUSIONS: Nabiximols administration is associated with brain connectivity increase of MS patients with spasticity. Modulation of sensorimotor cortical areas and cerebellum connectivity could play a role in nabiximols effect.

Late-onset multiple sclerosis presenting with cognitive dysfunction and severe cortical/infratentorial atrophy.

OBJECTIVE: Although cognitive dysfunction is a relevant aspect of multiple sclerosis (MS) from the earliest disease phase, cognitive onset is unusual thus jeopardizing early and accurate diagnosis. Here we describe 12 patients presenting with cognitive dysfunction as primary manifestation of MS with either mild or no impairment in non-cognitive neurological domains. METHODS: Twelve patients with cognitive onset who were subsequently diagnosed with MS (CI-MS) were included in this retrospective study. Twelve cognitively normal MS patients (CN-MS), 12 healthy controls and four patients having progressive supranuclear palsy (PSP) served as the reference population. RESULTS: Ten CI-MS patients had progressive clinical course and all patients had late disease onset (median age = 49 years; range = 40-58 years). Among cognitive functions, frontal domains were the most involved. Compared to CN-MS and healthy controls, significant cortical and infratentorial atrophy characterized CI-MS patients. Selective atrophy of midbrain tegmentum with relative sparing of pons, known as "The Hummingbird sign," was observed in eight CI-MS and in three PSP patients. DISCUSSION: Our observation suggests that MS diagnosis should be taken into consideration in case of cognitive dysfunction, particularly when associated with slowly progressive disease course and severe cortical, cerebellar and brainstem atrophy even in the absence of other major neurological symptoms and signs.

Fostering quality of life in young adults living with multiple sclerosis: a pilot study of a co-created integrated intervention.

Introduction: Multiple sclerosis (MS) is generally diagnosed at an early age, making the acceptance of this chronic disease challenging. Research dedicated to young adults with MS (YawMS) is still limited. A biopsychosocial co-created intervention for YawMS integrating social, physical and psychological activities was developed (ESPRIMO intervention) in order to improve the quality of life (QoL) and well-being. This pre-post intervention assessment study examines the feasibility of the ESPRIMO intervention and its signal of efficacy. Methods: Inclusion criteria were: age 18-45 years, MS diagnosis, Expanded Disability Status Scale score < 3.5. After giving informed consent, YawMS completed a battery of questionnaires, which was repeated after the intervention. The battery included a bespoke feasibility scale, the COOP/WONCA charts, and the Short Form-12 Health Survey (SF-12). Results: Fifty-three YAwMS were enrolled and 43 (81.1%) completed the intervention. The majority of the sample positively rated the pleasantness, usefulness and feasibility of the intervention. A significant change in the COOP/WONCA "general QoL" chart (t = 3.65; p < 0.01) and SF-12 mental wellbeing component (t = -3.17; p < 0.01) was found. Discussion: ESPRIMO is an innovative intervention that is feasible; preliminary results show an improvement in QoL and mental wellbeing. Further studies are needed to test its efficacy and evaluate future implementation in health services.Clinical trial registration: ClinicalTrials.gov, NCT04431323.

The role of ethnicity and native-country income in multiple sclerosis: the Italian multicentre study (MS-MigIT).

OBJECTIVE: Multiple sclerosis (MS) is a complex disorder in which environmental and genetic factors interact modifying disease risk and course. This multicentre, case-control study involving 18 Italian MS Centres investigated MS course by ethnicity and native-country economic status in foreign-born patients living in Italy. METHODS: We identified 457 MS patients who migrated to Italy and 893 age- and sex-matched native-born Italian patients. In our population, 1225 (93.2%) subjects were White Europeans and White Northern Americans (WENA) and 89 (6.8%) patients were from other ethnical groups (OEG); 1109 (82.1%) patients were born in a high-income (HI) Country and 241 (17.9%) in a low-middle-income (LMI) Country. Medical records and patients interviews were used to collect demographic and disease data. RESULTS: We included 1350 individuals (973 women and 377 men); mean (SD) age was 45.0 (11.7) years. At onset, 25.45% OEG patients vs 12.47% WENA (p = 0.039) had > 3 STIR spine lesions. At recruitment, the same group featured mean (SD) EDSS score of 2.85 (2.23) vs 2.64 (2.28) (p = 0.044) reached in 8.9 (9.0) vs 12.0 (9.0) years (p = 0.018) and underwent 1.10 (4.44) vs. 0.99 (0.40) annual MRI examinations (p = 0.035). At disease onset, patients from LMI countries had higher EDSS score than HI patients (2.40 (1.43) vs 1.99 (1.17); p = 0.032). DISCUSSION: Our results suggested that both ethnicity and socio-economic status of native country shape MS presentation and course and should be considered for an appropriate management of patients. To the best of our knowledge, this is the first study reporting on the impact of ethnicity in MS at an individual level and beyond an ecological population-perspective.

Promoting participatory research in chronicity: The ESPRIMO biopsychosocial intervention for young adults with multiple sclerosis.

Background: Co-creation allows to develop tailored interventions in chronicity and to increase patients' engagement. Considering the interacting nature of physical, psychological, and social domains in multiple sclerosis (MS), a biopsychosocial approach to care is crucial. Aims: This paper aims to present (i) an example of a co-creation process in the context of chronic diseases (ii) preferences and perspectives of young adults with multiple sclerosis (YawMS; aged 18-45) and healthcare professionals (HCPs) on the relevance, objectives, and modalities of a biopsychosocial intervention (named ESPRIMO) and on strategies/barriers to participation. Methods: A participatory mixed-method approach in three consecutive steps was implemented: online surveys with YawMS (n = 121) and HCPs (n = 43), online focus groups (FGs) with YawMS, consultation with an advisory board (AB) composed by YawMS, HCPs and researchers. For the survey, descriptive statistics and inductive content analysis have been used for quantitative and qualitative analysis, respectively. FGs and AB were used to deepen the understanding of the survey's results. Results: An integrated intervention is extremely relevant according to the perspectives of the main stakeholders. Helping disease acceptance, providing stress management strategies, and supporting emotional expression emerged as the most relevant psychological objectives according to participants. Having tangible benefits, being tailored, and fostering interpersonal relationships emerged as the main preferred characteristics of physical activity. Preferences emerged on the modalities and timing of the intervention, with a venue unrelated to the disease strongly supported. Both HCPs and YawMS highlighted as the most valuable advantages of conducting the intervention online the increased accessibility, while the main limit was the restriction to social interaction (recognized as already limited during the COVID-19 pandemic). Accessibility and lack of time resulted as the main barriers to participation. Conclusion: The co-creation process gave valuable information on preferences and perspectives of main stakeholders on objectives, modalities, and strategies to improve participation which has been used in the design of the ESPRIMO biopsychosocial intervention. Those results might inform future intervention development in the field of chronicity. The current paper outlined a co-creation methodology which might be replicated in future research on other conditions of vulnerability.

"If You Can't Control the Wind, Adjust Your Sail": Tips for Post-Pandemic Benefit Finding from Young Adults Living with Multiple Sclerosis. A Qualitative Study.

The COVID-19 outbreak has impacted the wellbeing of people worldwide, potentially increasing maladaptive psychological responses of vulnerable populations. Although young adults with multiple sclerosis (yawMS) might be at greater risk of developing psychological distress linked to the pandemic, they might also be able to adapt to stress and find meaning in adverse life events. The aim of the present study was to explore benefit finding in response to the pandemic in a sample of yawMS. As part of a larger project, data were collected using a cross-sectional, web-based survey. Benefit finding was analysed using a qualitative thematic approach; descriptive and inferential statistics were performed to describe the sample and compare sub-groups. Out of 247 respondents with mostly relapsing-remitting MS, 199 (31.9 ± 6.97 years) reported at least one benefit. Qualitative analysis showed that during the pandemic yawMS found benefits related to three themes: personal growth, relational growth, and existential growth. No differences in benefit finding were found between age sub-groups (18-30 vs. 31-45). Participants reported a wide range of benefits, some of which seem to be specific to MS or the pandemic. Results have been transformed into tips to be introduced in clinical practice to promote resilience in yawMS through meaning making.

A Bio-Psycho-Social Co-created Intervention for Young Adults With Multiple Sclerosis (ESPRIMO): Rationale and Study Protocol for a Feasibility Study.

BACKGROUND: Multiple sclerosis (MS), the most common neurological disease that causes disability in youth, does not only affect physical functions but is also associated with cognitive impairment, fatigue, depression, and anxiety and can significantly impact health-related quality of life (HRQoL). Since MS is generally diagnosed at a young age-a period of great significance for personal, relational, and professional development-adaptation can become highly challenging. Therefore, enhancing the competence of young people to adaptively cope with these potential challenges is of utmost importance in order to promote their potentialities and talents. It has been shown that psychological interventions targeting MS patients can enhance resilience and HRQoL and that regular physical activity (PA) and social engagement can improve psychological well-being. However, literature on the development of global interventions based on the bio-psycho-social model of the disease is missing. Even less attention has been paid to interventions dedicated to young adults with MS (YawMS) and to the involvement of patients in the development of such programs. AIMS: In collaboration with MS patients, this study aims to develop a bio-psycho-social intervention (ESPRIMO) for YawMS, aiming to improve their HRQoL and to explore its feasibility, acceptability, and effects. METHODS: To tailor the intervention to the specific needs of YawMS, "patient engagement principles" will be adopted in the co-creation phase, performing a web survey and focus groups with patients and healthcare professionals. In the intervention phase, a pilot sample of 60 young adults with MS will be enrolled. The co-created intervention, composed of group sessions over a 12-week period, will cover psycho-social strategies and include physical activities. Adopting a longitudinal, pre-post evaluation design, self-report questionnaires measuring HRQoL and other bio-psycho-social features (e.g., resilience, well-being, mindfulness traits, self-efficacy, perceived social support, psychological symptoms, illness perception, committed action, fatigue, attitudes, subjective norms, perceived behavioral control, motivation, perception of autonomy support for PA, barriers and intentions to PA) will be administered, the quantity and quality of PA will be measured, and a questionnaire developed by the authors will be used to evaluate the feasibility and acceptability of the ESPRIMO intervention.

Insights for Fostering Resilience in Young Adults With Multiple Sclerosis in the Aftermath of the COVID-19 Emergency: An Italian Survey.

Objective: Recent evidence has demonstrated that the COVID-19 pandemic is taking a toll on the mental health of the general population. The psychological consequences might be even more severe for patients with special healthcare needs and psychological vulnerabilities due to chronic diseases, such as multiple sclerosis (MS). Thus, we aimed to explore the psychological impact of this pandemic and of the subsequent healthcare service changes on young adults with MS living in Italy and to examine their coping strategies and preferences regarding psychological support in the aftermath of the pandemic. Methods: Data were collected using a cross-sectional, web-based survey advertised on social networks. We report both quantitative (descriptive statistics, t-tests, and one-way ANOVA) and qualitative data (inductive content analysis). Results: Two hundred and forty-seven respondents (mean age 32 ± 7 years), mainly with relapsing-remitting MS, from all Italian regions participated. Participants felt more worried, confused, sad, and vulnerable because of the disease "during" the pandemic in comparison to their self-evaluation of the period "before" the COVID-19 outbreak. Similarly, their perception of control over MS decreased "during" the pandemic in comparison to the retrospective evaluation of the period "before" the COVID-19 outbreak (p < 0.01). Canceled/postponed visits/exams were listed as the most frequent MS management changes, with modified/postponed pharmacological treatment representing the most stressful change. Psychological support in dealing with pandemic-related fears and improving MS acceptance and well-being was considered extremely important by almost 40% of the respondents. Different coping strategies were mentioned in the qualitative section of the survey, with social support, hobbies, and keeping busy being the most frequent ones. Conclusions: Considering the enormous impact of the pandemic on young adults with MS, we urge MS clinical centers to implement psychological support programs that address the potentially long-lasting psychological negative impact, thus fostering the therapeutic alliance that is being threatened by the infection prevention measures imposed during the pandemic, and promoting psychological resources for adaptively managing future waves of COVID-19.

Diagnostic features of initial demyelinating events associated with serum MOG-IgG.

BACKGROUND: Myelin oligodendrocyte glycoprotein (MOG)-IgG associated disorders are increasingly recognized as a distinct disease entity. However, diagnostic sensitivity and specificity of serum MOG-IgG as well as recommendations for testing are still debated. MATERIALS AND METHODS: Between October 2015 and July 2017 we tested serum MOG-IgG in 91 adult patients (49 females) with a demyelinating event (DE) not fulfilling 2010 McDonald criteria for MS at sampling, negative for neuromyelitis optica (NMO)-IgG and followed-up for at least 12 months. We assessed the sensitivity and specificity of a live-cell MOG-IgG assay for each final diagnosis at last follow-up, for the 2018 international recommendations for MOG-IgG testing, and for other combinations of clinical and laboratory characteristics. RESULTS: Clinical presentations included acute myelitis (n = 48), optic neuritis (n = 36), multifocal encephalomyelitis (n = 4), and brainstem syndrome (n = 3). Twenty-four patients were MOG-IgG positive. Sensitivity and specificity of MOG-IgG test applied to the 2018 international recommendations were 28.4% and 86.7%, while they were 42.1% and 88.6% when applied to DE of unclear aetiology as defined above with two or more among: 1_no periventricular and juxtacortical MS-like lesions on brain MRI; 2_longitudinally extensive MRI optic nerve lesion; 3_no CSF-restricted oligoclonal bands; 4_CSF protein > 50 mg/dl. CONCLUSIONS: Simplified requirements compared to those currently proposed for MOG-IgG testing could facilitate the applicability of the assay in the diagnosis of adults with DEs of unclear aetiology.

Dimethyl fumarate vs Teriflunomide: an Italian time-to-event data analysis.

BACKGROUND: The introduction of oral disease-modifying therapies (DMTs) for relapsing-remitting multiple sclerosis (RRMS) changed algorithms of RRMS treatment. OBJECTIVES: To compare the effectiveness of treatment with dimethyl fumarate (DMF) and teriflunomide (TRF) in a large multicentre Italian cohort of RRMS patients. MATERIALS AND METHODS: Patients with RRMS who received treatment with DMF and TRF between January 1st, 2012 and December 31st, 2018 from twelve MS centers were identified. The events investigated were "time-to-first-relapse", "time-to-Magnetic-Resonance-Imaging (MRI)-activity" and "time-to-disability-progression". RESULTS: 1445 patients were enrolled (1039 on DMF, 406 on TRF) and followed for a median of 34 months. Patients on TRF were older (43.5 ± 8.6 vs 38.8 ± 9.2 years), with a predominance of men and higher level of disability (p < 0.001 for all). Patients on DMF had a higher number of relapses and radiological activity (p < .05) at baseline. Time-varying Cox-model for the event "time-to-first relapse" revealed that no differences were found between the two groups in the first 38 months of treatment (HRt < 38DMF = 0.73, CI = 0.52 to 1.03, p = 0.079). When the time-on-therapy exceeds 38 months patients on DMF had an approximately 0.3 times lower relapse hazard risk than those who took TRF (HRt>38DMF = 3.83, CI = 1.11 to 13.23, p = 0.033). Both DMTs controlled similarly MRI activity and disability progression. CONCLUSIONS: Patients on DMF had higher relapse-free survival time than TRF group after the first 38 months on therapy.

2017 McDonald criteria for multiple sclerosis: Earlier diagnosis with reduced specificity?

BACKGROUND: McDonald criteria for multiple sclerosis (MS) diagnosis were revised in 2017. OBJECTIVE: Aim of our study was to evaluate and compare the sensitivity and specificity of 2017 and 2010 McDonald criteria in patients presenting with an initial demyelinating event (IDE). METHODS: We retrospectively identified patients with an IDE and collected clinical, MRI and CSF data in order to demonstrate fulfilment of 2010 and 2017 McDonald criteria. RESULTS: 2017 McDonald criteria showed 100% (86.8-100%) sensitivity and 13.8% (3.9-31.7%) specificity. CONCLUSION: 2017 McDonald criteria appear to have higher sensitivity but reduced specificity compared to 2010 McDonald criteria.

Biopsychosocial model of resilience in young adults with multiple sclerosis (BPS-ARMS): an observational study protocol exploring psychological reactions early after diagnosis.

INTRODUCTION: Multiple sclerosis (MS), the most common neurological disease causing disability in young adults, is widely recognised as a major stress factor. Studies have shown that the first years after the diagnosis are distressing in terms of adjustment to the disease and that MS negatively affects patients' psychological well-being, quality of life (QoL) and social functioning. However, the links between disease-specific variables at diagnosis, resilience and psychological adjustment of patients with MS remain largely unexplored, especially in adolescents and young adults. This observational study aims to fill the gap of knowledge on biopsychosocial characteristics and resilience of young adults with MS to evaluate the relationship among these variables and to develop a biopsychosocial model of resilience. METHODS AND ANALYSIS: Biological and clinical characteristics of young adults newly diagnosed with MS will be investigated by collecting clinical information, performing neurological examinations, MRI and analysing cerebrospinal fluid and blood biomarkers (eg, measures of inflammation), body composition, gut microbiota and movement/perceptual markers. Psychosocial characteristics (eg, psychological distress, coping strategies), QoL, psychological well-being and resilience will be assessed by self-report questionnaires. Comparative statistics (ie, analysis of variance or unpaired samples t-test, correlation and regression analyses) will be applied to evaluate the relationship among biological, psychological and social factors. The results are expected to allow a comprehensive understanding of the determinants of resilience in young patients with MS and to inform resilience interventions, tailored to young patients' specific needs, aiming to reduce the risk of maladaptive reactions to the disease and to improve psychological well-being and QoL. ETHICS AND DISSEMINATION: The study has been approved by the Verona University Hospital Ethics Committee (approval number: 2029CESC). The findings will be disseminated through scientific publications in peer-reviewed journals, conference presentations, social media and specific websites. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov (NCT03825055).

A case of multiple sclerosis and necrotizing autoimmune myopathy with anti-SRP antibodies.

Only few reports exist regarding the coexistence of multiple sclerosis (MS) and autoimmune myopathies. We describe the case of a man with a long history of undiagnosed left lower limb motor impairment who was hospitalized for subacute onset of a myopathic syndrome. In addition, neurological examination revealed sensory impairment and pyramidal signs in the left limbs. Muscle biopsy revealed a necrotizing myopathy and serum anti-signal recognition particle (SRP) antibodies were found. Brain and spinal cord MRI displayed several non-enhancing demyelinating lesions, and CSF-restricted oligoclonal bands were detected. Multimodal evoked potentials showed increased latency of central conduction. Total body PET-CT did not reveal malignancies. A final diagnosis of anti-SRP necrotizing autoimmune myopathy (NAM) and MS was made, and subsequent therapy with azathioprine resulted in a complete stability for both diseases during the follow up. To the best of our knowledge this is the first reported case of concomitant NAM and MS.

HPV-related papillary squamous cell carcinoma of the tonsil during treatment with fingolimod.

Fingolimod is a commonly used treatment for highly active relapsing-remitting multiple sclerosis (MS). We describe the case of a 50-year old man on fingolimod since 2011 who presented, in April 2017, with a voluminous swelling of the left tonsil. A left tonsillectomy was performed, and histological exam disclosed a papillary squamous cell carcinoma of the palatine tonsil, with an in situ hybridization positive for human papillomavirus (HPV)-16 DNA. Neither lymph nodes involvement nor other metastases were detected. Fingolimod was stopped as a precautionary measure in May 2017, and the patient currently continues his follow up at our Department. Immunocompromised patients are at risk for developing HPV-related malignancies probably in light of the suppression of T-cell immunity, therefore an increased risk for HPV activation in MS patients treated with disease modifying therapies (DMTs) characterized by a more pronounced immunosuppressant activity cannot be excluded. Given the absence of studies on larger cohorts of MS patients exposed to DMTs, additional monitoring for HPV infection during fingolimod treatment is not currently recommended. However, vigilance for this possible association is warranted.

Two Sisters with Leukoencephalopathy, Hearing Loss and Retinopathy: A Familial Case of Susac's Syndrome.

Aims: Susac’s syndrome is a rare clinical entity characterized by encephalopathy, sensorineural hearing loss and retinopathy caused by immune-mediated arteriole occlusion in the brain, retina and inner ear. No familial cases have been reported. We describe here the cases of two sisters who were seen at our Department for subacute neurological symptoms suggestive of a multifocal central nervous system disorder associated to hearing impairment and clinical or subclinical involvement of visual function. Presentation of Cases: The first case presented with a two-years history of progressive paraparesis, gait ataxia and cognitive dysfunction started at age 46; she also suffered from epileptic seizures since childhood and bilateral visual loss occurred between age 37 and 38. Her sister, aged 44, had a long-standing history of headache followed by sudden-onset bilateral hearing loss at age 35, which did not recover, and an acute episode of right-sided face paresthesias nine years later. Brain MRI showed multiple T2- hyperintense supratentorial lesions involving the corpus callosum in both sisters, with “snowball” appearance in the older one. Serum anti-endothelial cell antibodies assay was positive in the youngest patient. Discussion and Conclusion: After exclusion of other possible options, a diagnosis of Susac's syndrome looked probable for both sisters. Further studies investigating the pathogenesis and the genetic background of the disease are needed.
