Comparing Natural History of Early and Late Onset Pediatric Multiple Sclerosis
2022
Objective: This study was undertaken to describe and compare disease course and prognosis of early (ie, disease onset before age 11 years) and late (ie, disease onset after age 11 years) onset pediatric multiple sclerosis. Methods: Prospectively collected clinical information from Italian Multiple Sclerosis Register of 1993 pediatric multiple sclerosis patients, of whom 172 had early onset, was analyzed. Cox models adjusted for sex, baseline Expanded Disability Status Scale score, and disease-modifying treatments and stratified for diagnostic criteria adopted (Poser vs McDonald) were used to assess the risk of reaching irreversible Expanded Disability Status Scale scores of 3, 4, and 6, and…
Preliminary experience with a transcranial magnetic resonance-guided focused ultrasound surgery system integrated with a 1.5-T MRI unit in a series o…
2018
OBJECTIVETranscranial magnetic resonance–guided focused ultrasound surgery (tcMRgFUS) is one of the emerging noninvasive technologies for the treatment of neurological disorders such as essential tremor (ET), idiopathic asymmetrical tremor-dominant Parkinson’s disease (PD), and neuropathic pain. In this clinical series the authors present the preliminary results achieved with the world’s first tcMRgFUS system integrated with a 1.5-T MRI unit.METHODSThe authors describe the results of tcMRgFUS in a sample of patients with ET and with PD who underwent the procedure during the period from January 2015 to September 2017. A monolateral ventralis intermedius nucleus (VIM) thalamic ablation was pe…
Changes in magnetic resonance imaging disease measures over 3 years in mildly disabled patients with relapsing-remitting multiple sclerosis receiving…
2011
Abstract Background Conventional magnetic resonance imaging (MRI) has improved the diagnosis and monitoring of multiple sclerosis (MS). In clinical trials, MRI has been found to detect treatment effects with greater sensitivity than clinical measures; however, clinical and MRI outcomes tend to correlate poorly. Methods In this observational study, patients (n = 550; 18-50 years; relapsing-remitting MS [Expanded Disability Status Scale score ≤4.0]) receiving interferon (IFN) β-1a therapy (44 or 22 µg subcutaneously [sc] three times weekly [tiw]) underwent standardized MRI, neuropsychological and quality-of-life (QoL) assessments over 3 years. In this post hoc analysis, MRI outcomes and corre…
Cognitive impairment and its relation with disease measures in mildly disabled patients with relapsing-remitting multiple sclerosis: baseline results…
2009
Background Cognitive impairment is a common symptom of multiple sclerosis (MS), but the association between cognitive impairment and magnetic resonance imaging (MRI) disease measures in patients with relapsing–remitting (RR) MS is unclear. Objectives To study the prevalence of cognitive impairment and its relation with MRI disease measures in mildly disabled patients with RRMS. Methods Patients aged 18–50 years with RRMS (McDonald criteria) and an Expanded Disability Status Scale (EDSS) score ≤4.0, who were enrolled in the Cognitive Impairment in Multiple Sclerosis (COGIMUS) study, underwent baseline standardized MRI complete neurological examination and neuropsychological testing. Results…
A cross-sectional, multicentre study of the therapeutic management of multiple sclerosis relapses in Italy.
2013
Despite the existence of therapeutic guidelines, management of multiple sclerosis relapse remains heterogeneous. Optimisation of relapse outcome demands an improved understanding of the neurologist's therapeutic attitude towards relapse management, which is the aim of this study. Neurologists from 13 multiple sclerosis centres completed a questionnaire every time they assessed multiple sclerosis relapses. The questionnaire requested a guided description of the relapse's clinical characteristics and an indication of the prescribed therapy, supported with up to 3 out of 20 suggested reasons. Over 3 months, 368 questionnaires were collected. Median percentage (%) of 21 relapses resulting in a …
Multiple sclerosis in twins from continental Italy and Sardinia: a nationwide study.
2005
Knowledge about the balance between heritable and nonheritable risk in multiple sclerosis (MS) is based on twin studies in high-prevalence areas. In a study that avoided ascertainment limitations and directly compared continental Italy (medium-prevalence) and Sardinia (high-prevalence), we ascertained 216 pairs from 34,549 patients. This gives a twinning rate of 0.62% among MS patients, significantly less than that of the general population. In continental Italy, probandwise concordance was 14.5% (95% confidence interval, 5.1-23.8) for monozygotic and 4.0% (95% confidence interval, 0.8-7.1) for dizygotic twins. Results in Sardinia resemble those in northern populations but in limited number…
Risk of Persistent Disability in Patients With Pediatric-Onset Multiple Sclerosis
2021
Importance Availability of new disease-modifying therapies (DMTs) and changes of therapeutic paradigms have led to a general improvement of multiple sclerosis (MS) prognosis in adults. It is still unclear whether this improvement also involves patients with pediatric-onset MS (POMS), whose early management is more challenging. Objective To evaluate changes in the prognosis of POMS over time in association with changes in therapeutic and managing standards. Design, Setting, and Participants Retrospective, multicenter, observational study. Data were extracted and collected in May 2019 from the Italian MS Registry, a digital database including more than 59 000 patients. Inclusion criteria were…
Immunoproteasome LMP2 60HH Variant Alters MBP Epitope Generation and Reduces the Risk to Develop Multiple Sclerosis in Italian Female Population
2010
BackgroundAlbeit several studies pointed out the pivotal role that CD4+T cells have in Multiple Sclerosis, the CD8+ T cells involvement in the pathology is still in its early phases of investigation. Proteasome degradation is the key step in the production of MHC class I-restricted epitopes and therefore its activity could be an important element in the activation and regulation of autoreactive CD8+ T cells in Multiple Sclerosis.Methodology/principal findingsImmunoproteasomes and PA28-alphabeta regulator are present in MS affected brain area and accumulated in plaques. They are expressed in cell types supposed to be involved in MS development such as neurons, endothelial cells, oligodendroc…
Prevalence of fatigue in Parkinson disease and its clinical correlates
2014
Objective: To assess in a noninterventional setting the prevalence and severity of fatigue in patients with Parkinson disease (PD). Methods: This was a cross-sectional study conducted in Italian patients with PD. Objectives included the evaluation of the current prevalence and severity of fatigue in patients with PD measured using the 16-item Parkinson Fatigue Scale (PFS-16), distressing fatigue (defined as a PFS-16 mean score $3.3), and assessment of its clinical correlates. Results: A total of 402 patients were enrolled and 394 patients completed the PFS-16 questionnaire with a PFS-16 mean (6SD) score of 2.87 6 0.99. Of these, 136 patients (33.8%) reported distressing fatigue (PFS-16 mean…
Thyroid autoimmunity and dysfunction in multiple sclerosis patients during long-term treatment with interferon beta or glatiramer acetate: an Italian…
2014
Few long-term follow-up data are available on thyroid dysfunction (TD) in multiple sclerosis (MS) patients treated with glatiramer acetate (GA) or with interferon-beta (IFNb). In a cohort of 787 relapsing-remitting MS (RRMS) patients whom were followed up for 8 years, we observed an increased prevalence of TD and thyroid autoimmunity (TA) within the first year of IFNb treatment, regardless of the dose or frequency of administration, while no change was observed with GA treatment. The increased prevalence of TD and TA within the first year of IFNb treatment suggested the need for close monitoring of thyroid function and autoimmunity, though only during the first year of IFNb treatment. © Th…
