RESUMEN
BACKGROUND AND PURPOSE: The overall disability in patients with relapsing-remitting multiple sclerosis is likely to be partly rather than entirely attributed to relapse. MATERIALS AND METHODS: The aim was to investigate the determinants of recovery from first relapse and relapse-associated worsening (RAW) in relapsing-remitting multiple sclerosis patients from the Italian MS Registry during a 5-year epoch from the beginning of first-line disease-modifying therapy. To determine recovery, the functional system (FS) score was used to calculate the difference between the score on the date of maximum improvement and the score before the onset of relapse. Incomplete recovery was defined as a combination of partial (1 point in one FS) and poor recovery (2 points in one FS or 1 point in two FSs or any other higher combination). RAW was indicated by a confirmed disability accumulation measured by the Expanded Disability Status Scale score confirmed 6 months after the first relapse. RESULTS: A total of 767 patients had at least one relapse within 5 years of therapy. Of these patients, 57.8% experienced incomplete recovery. Age (odds ratio [OR] 1.02, 95% confidence interval [CI] 1.01-1.04; p = 0.007) and pyramidal phenotype were associated with incomplete recovery (OR = 2.1, 95% CI 1.41-3.14; p < 0.001). RAW was recorded in 179 (23.3%) patients. Age (OR = 1.02, 95% CI 1.01-1.04; p = 0.029) and pyramidal phenotype (OR = 1.84, 95% CI 1.18-2.88; p = 0.007) were the strongest predictors in the multivariable model. CONCLUSIONS: Age and pyramidal phenotype were the strongest determinants of RAW in early disease epochs.

OBJECTIVE: Assessing the risk of clinical and radiological reactivation during pregnancy and post partum in women with multiple sclerosis (MS) treated with natalizumab (NTZ) throughout pregnancy (LONG_EXP) compared with women interrupting treatment before (NO_EXP) and within >-30 days and ≤90 days from conception (SHORT_EXP), and describing newborns' outcomes. METHODS: Maternal clinical and radiological outcomes and obstetric and fetal outcomes were retrospectively collected and compared among groups (NO_EXP, SHORT_EXP, LONG_EXP). Predictors of clinical and radiological reactivation were investigated through univariable and multivariable analysis. RESULTS: 170 eligible pregnancies from 163 women referring to 29 Italian MS centres were included. Annualised relapse rate (ARR) was significantly lower in LONG_EXP (n=66, 0.02 (0.001-0.09)) compared with NO_EXP (n=31, 0.43 (0.21-0.75), p=0.002) and SHORT_EXP (n=73, 0.46 (0.30-0.66), p=0.0004) during pregnancy, and in LONG_EXP (0.12 (0.05-0.24)) compared with SHORT_EXP (0.30 (0.17-0.50), p=0.008) during post partum. Gadolinium-enhancing (Gd+) lesions were less frequent in LONG_EXP (n=6/50, 2.00%) compared with NO_EXP (n=9/21, 42.86%) and SHORT_EXP after delivery (n=17/49, 34.69%, p=0.010).Delaying NTZ resumption after delivery significantly increased the risk of relapses (OR=1.29 (95% CI 1.07 to 1.57), p=0.009) and Gd+ lesions (OR=1.49 (95% CI 1.17 to 1.89, p=0.001). Newborns' weight, length, head circumference and gestational age did not differ among groups after adjusting for confounders. Anaemia was tracked in 4/69 LONG_EXP newborns. Congenital anomaly rate was within the expected range for the untreated MS population. CONCLUSIONS: Our findings indicate that in women with MS treated with NTZ before conception, continuation of NTZ throughout pregnancy and its early resumption after delivery mitigate the risk of clinical and radiological reactivation. This approach has no major impact on newborns' outcomes.
RESUMEN
Autoimmune demyelinating diseases-including multiple sclerosis, neuromyelitis optica spectrum disorder, anti-myelin oligodendrocyte glycoprotein-associated disease, acute disseminated encephalomyelitis, and glial fibrillary acidic protein (GFAP)-associated meningoencephalomyelitis-are a heterogeneous group of diseases even though their common pathology is characterized by neuroinflammation, loss of myelin, and reactive astrogliosis. The lack of safe pharmacological therapies has purported the notion that cell-based treatments could be introduced to cure these patients. Among stem cells, mesenchymal stem cells (MSCs), obtained from various sources, are considered to be the ones with more interesting features in the context of demyelinating disorders, given that their secretome is fully equipped with an array of anti-inflammatory and neuroprotective molecules, such as mRNAs, miRNAs, lipids, and proteins with multiple functions. In this review, we discuss the potential of cell-free therapeutics utilizing MSC secretome-derived extracellular vesicles-and in particular exosomes-in the treatment of autoimmune demyelinating diseases, and provide an outlook for studies of their future applications.

Scarce data are available about the impact of natalizumab (NTZ) and ocrelizumab (OCR) on male fertility in relapsing-remitting multiple sclerosis (RRMS). In this case-control prospective study, the gonadal steroids and the sperm parameters have been analysed at the time of the RRMS diagnosis and after 12 months from the beginning of the investigated therapies. Sixteen men with RRMS and sixteen matched healthy controls were included. At enrolment and after 12 months on therapy, the gonadal steroids and the sperm parameters of men with RRMS did not differ from the healthy controls. In conclusion, therapy with NTZ and OCR had no impact on fertility status in our cohort of men with RRMS. Further randomized and prospective studies are needed.

BACKGROUND AND PURPOSE: The diagnosis of late-onset (age ≥50 years old) relapsing remitting multiple sclerosis (LORRMS) has been increasingly described in clinical practice, whereas data focusing on the specific therapeutic management of LORRMS are scarce. Our objective was to compare the effectiveness of injectable and oral first-line disease-modifying therapies (DMTs) in a cohort of LORRMS patients with time to first relapse, time to confirmed disability progression (CDP), and time to discontinuation. METHODS: This is a multicenter, observational, retrospectively acquired cohort study on LORRMS-naïve patients from the Italian MS Register who started either injectable or oral first-line DMTs between January 1, 2013 and December 31, 2017. LORRMS patients were divided into two groups, namely the injectable group (IG) and oral group (OG). Cox models adjusted with inverse probability-weighted propensity score were built for the investigated outcomes. RESULTS: Of a cohort of 3989 patients, 302 were enrolled (203 in the IG and 99 in the OG). The two cohorts did not differ in baseline characteristics. Time to first relapse did not show any difference between the two groups (hazard ratio [HR]: 1.10; 95% confidence interval [CI]: 0.50-2.46, p = 0.797). Furthermore, no differences were found between the two groups with respect to the risk of CDP (HR: 1.04; 95% CI: 0.35-3.06, p = 0.939), nor for the risk of DMT discontinuation (HR: 0.90; 95% CI: 0.17-2.08, p = 0.425). CONCLUSIONS: Real-world data from the Italian MS Register suggested that both injectables and oral first-line DMTs similarly controlled the investigated outcomes in LORRMS.

Multiple sclerosis (MS) refers to chronic inflammation of the central nervous system including the brain and spinal cord. Assessing for the presence of dysphagia in subjects with MS represents a challenge for neurologists in clinical practice. The aim of the present study was to verify the relationship between DYMUS scores, a patient-reported scale, and objective symptoms using the Dysphagia Outcome Severity Score (DOSS), based on fiber-optic endoscopy. Data were collected in a multicenter study. Two hundred and fifteen MS patients were enrolled, irrespective of self-reported dysphagia. DOSS revealed dysphagia in 122 subjects (56.7%). Compared with non-dysphagic subjects, the presence of dysphagia was related to more severe disability, longer disease duration, and a progressive form of the disease. A DYMUS score of 0 strongly correlated with a DOSS of 6 (sensitivity 100%) while DYMUS score of > 2 correlated with a DOSS < 7 (specificity 82%) of the self-reported scale. The DYMUS questionnaire can be a useful clinical tool for red-flagging patients who should undergo objective testing and referral to a otorhinolaryngologist.

INTRODUCTION: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder of the central nervous system (CNS) that causes progressive and irreversible damage in motor neurons. Different causal hypotheses include genetic, viral, traumatic and environmental mechanisms, such as exposure to heavy metals. The aim of this study was to compare metal/metalloid levels in cerebro-spinal fluid of ALS subtypes (spinal vs bulbar clinical onset). MATERIAL AND METHODS: This observational study consecutively screened all ALS patients referring to the Neurology Clinic of the University of Catania (Italy). Inductively coupled plasma mass spectrometry (ICP-MS) was used to quantify magnesium (Mg), cuprum (Cu), selenium (Se), iron (Fe), manganese (Mn), vanadium (V), zinc (Zn), alluminium (Al), arsenic (As), cobalt (Co), nickel (Ni), mercury (Hg), lead (Pb), cadmium (Cd) and palladium (Pd) levels. RESULTS: Thirty-seven patients were enrolled (62.2% females), median age of 65 years (IQR: 59-71 years). Thirty-one (83.8%) patients had a spinal onset and 6 (16.2%) a bulbar onset. Se and As levels were higher compared to the reference values (RV) both in spinal and bulbar onset, while Cu was higher than RV only in bulbar onset. Moreover, Cu (129.8 µg/L vs 29.8 µg/L), Fe (54.5 µg/L vs 33.3 µg/L), Mn (3.4 µg/L vs 1.8 µg/L), Zn (46.1 µg/L vs 35.7 µg/L), Al (12.2 µg/L vs 6.7 µg/L), Ni (2.80 µg/L vs 1.40 µg/L), and Pb (0.60 µg/L vs 0.30 µg/L) levels were higher in bulbar than in spinal onset, conversely As was slightly higher in spinal than in bulbar onset (1.40 µg/L vs 1.10 µg/L). Overall, Cu (129 µg/L vs 31 µg/L), Fe (92.2 µg/L vs 32.9 µg/L), Mn (3.35 µg/L vs 1.80 µg/L), Zn (56.5 µg/L vs 35.2 µg/L), Al (14.45 µg/L vs 6.70 µg/L), and Cd (0.40 µg/L vs 0.08 µg/L) levels were higher in patients with disease duration less than 19 months. CONCLUSION: Our results supported the hypothesis that metals/metalloids with neurotoxic effects could be involved in the etiology of ALS, showing higher levels of Cu, Se and As. Relevant differences in Cu and Mn levels were found between bulbar and spinal onset patients.

This work presents the design of a discrete second-generation voltage conveyor (VCII) and its capability to be used as electronic interface for silicon photomultipliers. The design addressed here exploits directly at the transistor level, with commercial components, the proposed interface; the obtained performance is valuable considering both the discrete elements and the application. The architecture adopted here realizes a transimpedance amplifier that is also able to drive very high input impedance, as usually requested by photons detection. Schematic and circuital design of the discrete second-generation voltage conveyor is presented and discussed. The complete circuit interface requires a bias current of 20 mA with a dual 5V supply voltage; it has a useful bandwidth of about 106 MHz, and considering also the reduced dimensions, it is a good candidate to be used in portable applications without the need of high-cost dedicated integrated circuits.
RESUMEN
BACKGROUND: Few data are available on very long-term follow-up of pediatric multiple sclerosis (MS) patients treated with disease modifying treatments (DMTs). OBJECTIVES: To present a long-term follow-up of a cohort of Pediatric-MS patients starting injectable first-line agents. METHODS: Data regarding treatments, annualized relapse rate (ARR), Expanded Disability Status Scale (EDSS) score, and serious adverse event were collected. Baseline characteristics were tested in multivariate analysis to identify predictors of disease evolution. RESULTS: In total, 97 patients were followed for 12.5 ± 3.3 years. They started therapy at 13.9 ± 2.1 years, 88 with interferons and 9 with copaxone. During the whole follow-up, 82 patients changed therapy, switching to immunosuppressors/second-line treatment in 58% of cases. Compared to pre-treatment phase, the ARR was significantly reduced during the first treatment (from 3.2 ± 2.6 to 0.7 ± 1.5, p < 0.001), and it remained low during the whole follow-up (0.3 ± 0.2, p < 0.001). At last observation, 40% had disability worsening, but EDSS score remained <4 in 89%. One patient died at age of 23 years due to MS. One case of natalizumab-related progressive multifocal encephalopathy (PML) was recorded. Starting therapy before 12 years of age resulted in a better course of disease in multivariate analysis. CONCLUSION: Pediatric-MS patients benefited from interferons/copaxone, but the majority had to switch to more powerful drugs. Starting therapy before 12 years of age could lead to a more favorable outcome.

BACKGROUND: It is common that the epidemiology of multiple sclerosis (MS) varies with geography and ethnicity. Recent studies show a continuous growth of incidence and prevalence in Sicily, despite the controversial "latitude gradient theory." OBJECTIVES: The aim of our study is to ascertain incidence and prevalence rates of MS in the city of Biancavilla, Sicily, Southern Italy. METHOD: Case ascertainment approach and a clinical database collecting data of MS cases to Biancavilla, according to McDonald 2011 and Thompson 2018 criteria, from 1992 to 2018, have been used to the study. We further collected information regarding the familiarity of patients with Mesothelioma, highly incident in this geographic area. RESULTS: The results showed an increase of the mean annual incidence for the period 2012-2018 (16.8/100,000) compared to 1992-1996 (4.5/100,000), and a standardized incidence ratio of 1.41 (95% CI 0.74-2.45). On December 31, 2018, 70 patients suffering from definite MS and living in Biancavilla yielded a crude prevalence of 292.3 per 100,000 (198.2/100,000 for men; 380.7/100,000 for women) with a standardized morbidity ratio of 2.3 (95% CI 1.8-2.9). CONCLUSIONS: Our data confirmed Biancavilla is an area at high risk for MS, ascribable to increased survival, improved ascertainment, or maybe related to a genetic or environmental risk. At the time, any relation with mesothelioma was excluded.

OBJECTIVES: We compared the clinical, laboratory, and radiological features of different subgroups of acute transverse myelitis (ATM) diagnosed according to the criteria established by the Transverse Myelitis Consortium Working Group (TMCWG) as well as of non-inflammatory acute transverse myelopathies (NIATM) to identify possible short- and long-term prognostic factors. METHODS: A multicenter and retrospective study comprising 110 patients with ATM and 15 NIATM admitted to five Italian neurological units between January 2010 and December 2014 was carried out. RESULTS: A significantly higher frequency of isolated sensory disturbances at onset in ATM than in NIATM patients (chi-square = 14. 7; P = 0.005) and a significantly higher frequency of motor symptoms in NIATM than ATM (chi-square = 12.4; P = 0.014) was found. ATM patients with high disability at discharge had more motor-sensory symptoms without (OR = 3.87; P = 0.04) and with sphincter dysfunction at onset (OR = 7.4; P = 0.0009) compared to those with low disability. Higher age (OR = 1.08; P = 0.001) and motor-sensory-sphincter involvement at onset (OR = 9.52; P = 0.002) were significantly associated with a high disability score at discharge and after a median 1-year follow-up. CONCLUSIONS: The diagnosis of ATM may prevail respect to that of NIATM when a sensory symptomatology at onset occurs. In ATM, patients older and with motor-sensory involvement with or without sphincter impairment at admission could experience a major risk of poor prognosis both at discharge and at longer time requiring a timely and more appropriate treatment.

In the era of novel agents and immunotherapies in solid and liquid tumors, there is an emerging need to understand the cross-talk between the neoplastic cells, the host immune system, and the microenvironment to mitigate proliferation, survival, migration and resistance to drugs. In the microenvironment of hematological tumors there are cells belonging to the normal bone marrow, extracellular matrix proteins, adhesion molecules, cytokines, and growth factors produced by both stromal cells and neoplastic cells themselves. In this context, myeloid suppressor cells are an emerging sub-population of regulatory myeloid cells at different stages of differentiation involved in cancer progression and chronic inflammation. In this review, monocytic myeloid derived suppressor cells and their potential clinical implications are discussed to give a comprehensive vision of their contribution to lymphoproliferative and myeloid disorders.

Cognitive impairment (CI) has been shown to be severe in patients with progressive forms of multiple sclerosis (MS), and the most frequently impaired domains are sustained attention, information processing speed, memory, and executive functions. In contrast to relapsing forms of MS, where studies have shown favorable results from cognitive rehabilitation, there is a lack of data on cognitive rehabilitation in progressive forms of MS. A specific approach in assessing CI and in designing and administering rehabilitation training for patients with progressive forms of MS is needed.

Incidence of multiple sclerosis (MS) has steeply increased over time during the last 30 years in the city of Catania. We carried out a population-based case-control study to evaluate the possible role of both environmental and genetic factors. From 1975 to 2004 in Catania, 367 MS patients diagnosed according to the Poser's criteria had the onset of disease. A sample of MS patients was randomly selected from this incident cohort. Three controls matched by age and sex were randomly selected from the rosters of 14 GPs. Controls were proportionally selected according to the distribution by municipality of the target population using a multistage sampling methods. All cases and controls underwent a face-to-face interview to record information concerning environmental factors and a blood sample was taken for serological and genetic analysis. 164 MS patients (64 % women; mean age of 46.4 ± 10.7) and 481 controls (69 % women; mean age of 47.7 ± 14.8) were enrolled in the study. The distribution of the whole population and the selected controls by municipalities was similar. A blood sample was taken from 150 MS cases and from 337 controls. At the end of the enrolment, we obtained a representative sample of the MS cases and population controls avoiding possible selection bias. Participation rate was very high also concerning the collection of biological specimens.

OBJECTIVES: Data on pregnancy long-term effects on multiple sclerosis (MS) course are still controversial; whether experiencing more than one pregnancy exposes one to risk of the disability's accrual is still unknown. We investigated differences existing in terms of disability progression among women with MS (wwMS) who had one or more children after their MS onset. METHODS: Monoparous and multiparous wwMS were enrolled from the Catania MS Center, Italy, in a monocenter retrospective study. A Cox proportional hazards model was used to examine the effect of the number of parities on time from MS disease onset to EDSS 4.0 and 6.0. The study protocol was approved by the local Ethical Committee. RESULTS: During the seven years of observation, 32.1% and 23.2% of the monoparous group reached expanded disability disease status (EDSS) 4.0 and 6.0 respectively, compared to 13.3% and 3.3% of the multiparous group (p = 0.057 and p = 0.017; respectively). The Kaplan-Meier curve analysis showed no statistically-significant differences between the two groups in reaching the two milestones. The multiparous group showed a longer time to reach the EDSS 4.0 (3.5 vs. 2.6 years, log-rank 0.57, p = 0.45). The Cox regression analysis showed that the EDSS at the time of first pregnancy (Exp(B) 9.4, CI 4.5-19.7, p< 0.001) and the time from MS onset to first pregnancy (Exp(B) 0.96, CI = 0.93-0.98, p < 0.05) were significant predictors of reaching the EDSS 4.0, whereas a model including only the EDSS one year after the first pregnancy significantly predicted (Exp(B) value of 6.4, CI 2.6-15.4, p < 0.001) the reaching of EDSS 6.0. CONCLUSIONS: Our results suggest that experiencing more than one pregnancy could not convey a different clinical outcome in wwMS. Further research is needed to confirm our results.

Using the term of progressive multiple sclerosis (PMS), we considered a combined population of persons with secondary progressive MS (SPMS) and primary progressive MS (PPMS). These forms of MS cannot be challenged with efficacy by the licensed therapy. In the last years, several measures of risk estimation were developed for predicting clinical course in MS, but none is specific for the PMS forms. Personalized medicine is a therapeutic approach, based on identifying what might be the best therapy for an individual patient, taking into account the risk profile. We need to achieve more accurate estimates of useful predictors in PMS, including unconventional and qualitative markers which are not yet currently available or practicable routine diagnostics. The evaluation of an individual patient is based on the profile of disease activity.Within the neurology field, PMS is one of the fastest-moving going into the future.

Multiple sclerosis (MS) is a complex disease triggered by environmental and genetic agents, and clinically characterized by bout onset (BOMS) or progressive onset (PrMS). We collected clinical and familial aggregation data in a cohort of 518 Italian PrMS patients, and compared with 400 BOMS cases. An increased prevalence of MS in first-degree relatives of Italian PrMS was found. Familial aggregation is not influenced by probands' clinical course, and there is no disease course concordance within MS families. These data are useful in counseling MS patients affected with different clinical courses of the disease.

Alemtuzumab, a humanized anti-CD52 monoclonal antibody, is approved for treatment of highly active relapsing multiple sclerosis (MS) but requires vigilant post-treatment monitoring due to associated risks. The prescription of subsequent therapies following Alemtuzumab, as mandated by label guidance for a treatment-free period of at least 5 years, presents a complex challenge, particularly if there is concurrent conversion to secondary progressive disease course. We described a case-series of five patients starting therapy with Siponimod and followed up for 12 months period converted to secondary progressive MS previously exposed to Alemtuzumab. All patients received Siponimod 2 mg. Clinical evaluation measured with Expanded Disability Status Scale and cognitive evaluation measured with Brief International Cognitive Assessment for Multiple Sclerosis were stable after 12 months on therapy. No severe lymphopenia was recorded, nor serious adverse events. In conclusion, the long-term management of patients treated with Alemtuzumab transitioning to secondary progressive MS requires a proactive and multidisciplinary approach. By addressing the challenges associated with treatment limitations and short-term monitoring recommendations while considering alternative therapeutic options like Siponimod, clinicians can optimize outcomes and ensure continuity of care for individuals with MS.
