RESUMEN
Introduction: Synchronous telehealth (ST) consists of the remote real-time delivery of health services. COVID-19 pandemic has pressed the use of ST and forced neurologists to deliver telehealth services. The aim of this study was to obtain the actual picture of ST accessibility/interest and to evaluate the user satisfaction in patients with multiple sclerosis (MS) during the COVID-19 pandemic. Methods: The study consisted of two phases. First, a hard-copy questionnaire ("Telehealth Identity Card" [TIC]), including only yes/no questions, filled in the presence of a neurologist, and investigating the technical/practical access and the willingness/interest of MS patients to the telehealth services, was obtained from 600 consecutive outpatients, with no time limit for answering. Second, a fully filled "Televisit Satisfaction Questionnaire" (TSQ) was obtained from 100 consecutive patients that underwent a televisit. Statistical analysis applied the t test for normally distributed variables and the Mann-Whitney U test for ordinal. Logistic univariate and multivariate regressions were applied to predict televisit availability on the base of demographic variables. Results: Statistical analysis was performed on 552/600 consecutive TIC (92%). Of them, 464/552 (84%) of the MS patients declared to possess the tools and to be interested in telehealth services. Compared with noninterested patients, they were younger (mean age: 44.0 vs. 49.8, p < 0.001) and with lower disability (mean Expanded Disability Status Scale: 2.5 vs. 3.3, p < 0.01). From TSQ, it emerged that 95% agree or strongly agree that televisit respected timelines, saved time and money, was conducted with respect to privacy, can be a useful tool for monitoring disease and therapy, and expressed their availability for further televisits. Discussion: A great majority of MS patients living in Padua Province were interested in telehealth. High satisfaction and the willingness for further televist were expressed. Telehealth services can help neurologists to manage the increasing number of MS patients and their complex therapeutic monitoring.
RESUMEN
BACKGROUND AND OBJECTIVES: Although pediatric-onset multiple sclerosis (POMS) is characterized by a more rapid accumulation of CNS inflammation than adult-onset MS (AOMS), the therapeutic algorithms applied in POMS are usually based on AOMS therapeutic outcomes. To define a high-efficacy treatment (HET)-based strategy to treat POMS, we designed an observational retrospective study aimed at evaluating the efficacy and safety of natalizumab (NTZ) in naïve POMS and AOMS. METHODS: Starting from 160 patients, we applied a 2:1 (adult:pediatric) matching on propensity scores and obtained 32 patients with NTZ-treated POMS and 64 with AOMS, estimated from a multivariable logistic regression model. All patients were clinically and radiologically followed up every 6 months for a mean period of 46.0 ± 26.9 months. RESULTS: Following re-baseline at month 6, no difference (log-rank test: p = 0.924) in new and enlarging T2 white matter lesions, postcontrast T1 lesions, and relapse rate were observed between POMS and AOMS throughout the study. Progression independent of relapse activity (PIRA) was never observed in POMS, while 9 of 64 patients with AOMS (12.5%) had PIRA events during the follow-up (40.0 ± 25.9 months; log-rank p value 0.0156). JCV seroconversion rate during NTZ infusion did not differ between POMS and AOMS (log-rank test p = 0.3231). Finally, no serious adverse event was observed in both POMS and AOMS. DISCUSSION: The favorable outcomes observed on clinical, especially in PIRA, and radiologic parameters strongly support the use of NTZ as a first-choice HET in POMS.

Introduction: Microglia (MG) is suggested to play an immunopathological role of in Multiple Sclerosis (MS). Since hyper-reflective foci (HRF) might mark MG activation, in vivo analysis by Optic Coherence Tomography (OCT) in MS patients under disease modifying therapies may help to clarify MS immunopathology as well as drug's mechanism of intrathecal action. Objective: To analyze HRF in patients treated with Natalizumab (NTZ), a high efficacy therapy for MS. Materials and methods: The effect of NTZ on the retina of 36 Relapsing-Remitting MS patients was investigated in a prospective, single-center study. OCT was performed immediately before the first infusion and then between infusion 3 and 4, infusion 6 and 7, infusion 11 and 13. Peripapillary and macular scans were acquired, evaluating peripapillary RNFL thickness, macular volumes (vertical scans), and HRF count (horizontal scan) in Ganglion Cell Layer (GCL), Inner Plexiform Layer (IPL) and Inner Nuclear Layer (INL). Clinical examination was performed every six months. Results: HRF count significantly increased under NTZ therapy (p<0.001) in both GCL (18.85 ± 6.93 at baseline, 28.24 ± 9.55 after 12 months) and IPL (25.73 ± 7.03 at baseline, 33.21 ± 8.50 after 12 months) but remained stable in INL (33.65 ± 7.76 at baseline, 36.06 ± 6.86 after 12 months, p=0.87), while no relevant modification of pRNFL and macular volumes were observed during the study. EDSS remained stable and no clinical relapse was observed between month 6 and 12. Conclusion: In RRMS NTZ affects HRF count in GCL and IPL, but not in INL, suggesting that NTZ does not impact on some aspects of MS immunopathology.

BACKGROUND: In multiple sclerosis (MS), imaging biomarkers play a crucial role in characterizing the disease at the time of diagnosis. MRI and optical coherence tomography (OCT) provide readily available biomarkers that may help to define the patient's clinical profile. However, the evaluation of cortical and paramagnetic rim lesions (CL, PRL), as well as retinal atrophy, is not routinely performed in clinic. OBJECTIVE: To identify the most significant MRI and OCT biomarkers associated with early clinical disability in MS. METHODS: Brain, spinal cord (SC) MRI, and OCT scans were acquired from 45 patients at MS diagnosis to obtain: brain PRL and non-PRL, CL, SC lesion volumes and counts, brain volumetric metrics, SC C2-C3 cross-sectional area, and retinal layer thickness. Regression models assessed relationships with physical disability (Expanded Disability Status Scale [EDSS]) and cognitive performance (Brief International Cognitive Assessment for Multiple Sclerosis [BICAMS]). RESULTS: In a stepwise regression (R2 = 0.526), PRL (ß = 0.001, p = 0.023) and SC lesion volumes (ß = 0.001, p = 0.017) were the most significant predictors of EDSS, while CL volume and age were strongly associated with BICAMS scores. Moreover, in a model where PRL and non-PRL were pooled, only the contribution of SC lesion volume was retained in EDSS prediction. OCT measures did not show associations with disability at the onset. CONCLUSION: At MS onset, PRL and SC lesions exhibit the strongest association with physical disability, while CL strongly contribute to cognitive performance. Incorporating the evaluation of PRL and CL into the initial MS patient assessment could help define their clinical profile, thus supporting the treatment choice.
RESUMEN
INTRODUCTION: Multiple sclerosis (MS) is a chronic neurodegenerative disease that leads to impaired cognitive function and accumulation of disability, with significant socioeconomic burden. Serious unmet need in the context of managing MS has given rise to ongoing research efforts, leading to the launch of new drugs planned for the near future, and subsequent concerns about the sustainability of healthcare systems. This study assessed the changes in the Italian MS market and their impact on the expenditures of the Italian National Healthcare Service between 2023 and 2028. METHODS: A horizon-scanning model was developed to estimate annual expenditure from 2023 to 2028. Annual expenditure for MS was calculated by combining the number of patients treated with each product (clinical inputs) and the yearly costs of therapy (economic inputs). Baseline inputs (2020-2022) were collected from IQVIA® real-world data, while input estimation for the 5-year forecast was integrated with analog analyses and the insights of clinicians and former payers. RESULTS: The number of equivalent patients treated in 2028 in Italy was estimated at around 67,000, with an increase of 10% versus 2022. In terms of treatment pattern evolution, first-line treatments are expected to reduce their shares from 47% in 2022 to 27% in 2028, and Bruton tyrosine kinase inhibitors are expected to reach 23% of patient shares. Overall, expenditure for MS is estimated to decrease from 721 million in 2022 to 551 million in 2028, mainly due to losses of exclusivity and renegotiation of drug prices. CONCLUSION: Despite the increase in the number of patients treated for MS and the launch of new molecules that will reach high market penetration, the model confirmed sustainability for the Italian National Healthcare Service.
