• NFL predicted the occurrence of clinical and radiological relapses in the first two years after the time of diagnosis. • NFL did not correlate with EDSS scores attributed at the time of diagnosis and at follow-up neurological examinations. • NFL levels did not correlate with SDMT scores at baseline and at subsequent evaluations. Among biomarkers of axonal damage, neurofilament light chains (NFL) seem to play a major role, representing a promising and interesting tool in Multiple Sclerosis (MS). Our aim was to explore the predictive role of cerebrospinal fluid (CSF) NFL in patients with a recent diagnosis of MS, naïve to any MS therapy. We retrospectively collected data of patients diagnosed with MS, referred to the Neurology Clinic of the University-Hospital G. Rodolico of Catania between January 1st 2005 and December 31st 2015. All patients underwent CSF collection at the time of MS diagnosis and were followed-up for at least three years afterwards. NFL levels were measured in CSF samples with Simoa NFLight advantage kit at the CRESM (University Hospital San Luigi Gonzaga, Orbassano, Torino). NFL levels were expressed as LogNFL. Symbol Digit Modalities test (SDMT) was performed at baseline, at 1-year and at 3-year follow-up. Multivariate logistic regression analysis was performed to investigate LogNFL as a potential risk factor of different clinical outcomes. 244 MS patients (230 relapsing-remitting, RRMS; 94.3 %), with a mean age at diagnosis of 37.0 ± 11.1 years, were recruited. LogNFL did not correlate neither with EDSS score at diagnosis and at subsequent follow-up up to 12 years, nor with SDMT performed at diagnosis, at 1 year and at 3 years. LogNFL were an independent factor for the occurrence of at least one relapse during the first two years after MS diagnosis (OR = 2.75; 95 % CI 1.19–6.31; p = 0.02) and for the occurrence of gadolinium-enhanced (Gd+) lesions during the first 2 years from diagnosis at brain and spine MRI scans (OR = 3.45, 95 % CI 1.81–6.57; p < 0.001). The detection of CSF NFL at the time of MS diagnosis can be a useful support to predict the two-year risk of clinical and radiological relapses, thus affecting therapeutic choices in the very early phases of the disease.

Highlights • Off-label use of Rituximab for Demyelinating disease of the central nervous system is increasing. • No guidelines on intervals and dosages of administration are available. • Disease control was obtained in about 65% of our patients. • Only one patient experienced severe adverse event, that is a severe lymphopenia. • About 25% of our patients were naïve to any treatment. Abstract Background Rituximab (RTX), a monoclonal antibody targeting the CD20+ B lymphocytes, deserves major attention as therapeutic option in the treatment of demyelinating disorders of the central nervous system (DDCNS). We reported our clinical experience with the use of RTX in terms of efficacy and safety in persons suffering from DDCNS. Methods An Italian single-center observational analysis of patients who underwent RTX treatment between 2011 and 2017 was performed at MS center of Catania, Italy. No evidence of disease activity (NEDA) was applied to evaluate the response to RTX. CD19+ and CD20+ counts were collected along therapy. RTX-related adverse events were recorded. Results Eleven patients with MS, four with NMOSD and two with NMO were enrolled. Out of them, 4/17 were naïve to previous treatments. According to NEDA status, 11/17 got NEDA3 status at the follow-up. Six patients had relapses (two had a single relapse and four had multiple relapses). One patient with primary progressive MS and one with relapsing remitting MS stopped RTX, the last one for severe lymphopenia. Conclusions RTX showed efficacy to impact DDCNS worsening with an acceptable safety profile. [ABSTRACT FROM AUTHOR]

• The therapeutic approach for women with Multiple Sclerosis might favor the use of high efficacy drugs before and during pregnancy. • High-efficacy therapies are associated with less frequent relapses in the year after pregnancy. • The use of high-efficacy treatment during pregnancy is not associated with increased safety concerns for mothers and offspring. • Fertility indicators for women with Multiple Sclerosis seem not to be reduced if compared with data recorded in the Italian general population. Pregnancy planning is a relevant issue in the management of Multiple Sclerosis (MS), which commonly involves women of childbearing age. Increased knowledge and a wider therapeutic scenario could have changed the approach of neurologists towards this topic over time. Our aim was to describe how pregnancy planning and management for women with MS have changed in the last 15 years. We retrospectively collected clinical data of female patients with relapsing-remitting MS (RRMS), referred to the Neurology Clinic of the University-Hospital "Policlinico G. Rodolico" of Catania, who became pregnant between 2005-2020. We compared data about MS and pregnancy between two time periods according to pregnancy onset (2005-2012; 2013-2020). 190 patients with RRMS carried 253 pregnancies in the observation period. Women undergoing a pregnancy in the last period (2013-2020), as compared to women who had pregnancy in the first period (2005-2012), were older (p<0.01), more often treated before and during pregnancy with high-efficacy disease-modifying drugs (DMD) (p<0.001), and exhibited lower annualized relapse rates (ARR) before (p=0.01) and after pregnancy (p<0.001). Results from our experience suggest that nowadays DMD are more frequently used in women of childbearing age, even during pregnancy, leading to a reduced ARR before and after delivery in absence of increased obstetric complications.

• Cognitive profile and physician-based and patients-reported outcomes could have a considerable impact on the disease management and on treatment decision making. • According to the Control Preference Scale, more than 50% of patients who needed to change therapy chose a "collaborative" role in making treatment decision. • Cognitive profile with SDMT seems to influence patients' preference on treatment decision. Clinicians are increasingly recognizing the importance of shared decision-making in complex treatment choices, highlighting the importance of the patient's rationale and motivation for switching therapies. This study aimed to evaluate the association between different modalities of changing multiple sclerosis (MS) treatments, cognitive profile and attitude and preferences of patients concerning treatment choice. This multicenter cross-sectional study was conducted at 28 Italian MS centers in the period between June 2016 and June 2017. We screened all MS patients treated with any DMT, with a treatment compliance of at least 80% of therapy administered during the 3 last months who needed to modify MS therapy because of efficacy, safety or other reasons during a follow-up visit. At the time of switching the symbol digit modalities test (SDMT) and the Control Preference Scale (CPS) were evaluated. According to the CPS, patients were classified as "active" (i.e. who prefer making the medical decision themselves), "collaborative" (i.e. who prefer decisions be made jointly with the physician), or "passive" (i.e. who prefer the physician make the decision). Out of 13,657 patients recorded in the log, 409 (3%) changed therapy. Of these, 336 (2.5%) patients, 69.6% were female and with mean age 40.6 ± 10.5 years, were enrolled. According to the CPS score evaluation, a significant high percentage of patients (51.1%) were considered collaborative, 74 patients (22.5%) were passive, and 60 (18.2%) patients were active. Stratifying according to CPS results, we found a higher SDMT score among collaborative patients compared to active and passive ones (45.8 ± 12.3 versus 41.0 ± 13.2 versus 41.7 ± 12.8, p < 0.05). In this study, the CPS evaluation showed that more than 50% of patients who needed to change therapy chose a "collaborative" role in making treatment decision. Cognitive profile with SDMT seems to correlate with patients' preference on treatment decision, showing better scores in collaborative patients. [ABSTRACT FROM AUTHOR]

Multiple sclerosis (MS) is a highly complex chronic inflammatory disease, in which a diagnostic delay could reduce the available therapeutic options. Our aim was to identify factors contributing to diagnostic delay in a MS population living in the municipality of Biancavilla. This retrospective population-based study consecutively selected patients with MS diagnosed from 1992 to 2018 and resident in the city of Biancavilla. Socio-demographic and clinical data were collected through the iMed database. Date of final MS diagnosis was obtained and diagnostic delay was calculated. A total of 70 patients (66.7% women) were found affected by MS according to the 2011 McDonald criteria in the municipality of Biancavilla in the period between 2005 and 2010. The mean diagnostic delay in the MS cohort of Biancavilla was 33.8 ± 56 months [median 19.5, range 1–315]. The multivariate logistic regression confirmed that age ≥ 40 years, lower educational level (1–5 years) and motor symptoms at onset were associated to longer diagnostic delay. In this population-based study a mean delay of about 30 months occurred between initial symptoms and the MS diagnosis. Older age at onset, lower education level and motor symptoms at onset were associated to longer MS diagnostic delay. [ABSTRACT FROM AUTHOR]
