Herpes zoster preceding neuromyelitis optica spectrum disorder: casual or causal relationship? A systematic literature review.

Neuromyelitis optica spectrum disorder (NMOSD) is a severe, inflammatory, immune-mediated astrocytopathy of the central nervous system, characterized by recurrent inflammatory events primarily involving optic nerves and the spinal cord. Recently, a triggering role of infectious events in the development of NMOSD has been suggested. Varicella zoster virus (VZV) is the agent most involved, although the linkage with anti-aquaporin-4 antibodies is so far unknown.

Secondary cluster headache due to a contralateral demyelinating periaqueductal gray matter lesion.

Objectives/background: Tension-type headache and migraine without aura are the most common primary headaches occurring in people with demyelinating diseases, whereas cluster headache (CH) can be considered exceptional. The location of demyelinating lesions could be strategic in these cases, involving areas interacting with the trigeminovascular system.

Methods And Results: We report a case of a 54-year-old woman with right-sided CH as the initial manifestation of multiple sclerosis and showing a left dorsal brainstem lesion on magnetic resonance imaging, in the region of the dorsal longitudinal fasciculus (DLF).

Switch from sequestering to anti-CD20 depleting treatment: disease activity outcomes during wash-out and in the first 6 months of ocrelizumab therapy.

Objectives: Switching between treatments is an opportunity for patients with multiple sclerosis (MS) to ameliorate disease control or safety. The aim of this study was to investigate the impact of switching from fingolimod (FTY) or natalizumab (NTZ) to ocrelizumab (OCR) on disease activity.

Methods: We retrospectively enrolled 165 patients treated with OCR from 11 MS centres.

Exit Strategies in Natalizumab-Treated RRMS at High Risk of Progressive Multifocal Leukoencephalopathy: a Multicentre Comparison Study.

The main aim of the study is to evaluate the efficacy and safety profile of ocrelizumab (OCR), rituximab (RTX), and cladribine (CLA), employed as natalizumab (NTZ) exit strategies in relapsing-remitting multiple sclerosis (RRMS) patients at high-risk for progressive multifocal leukoencephalopathy (PML). This is a multicentre, retrospective, real-world study on consecutive RRMS patients from eleven tertiary Italian MS centres, who switched from NTZ to OCR, RTX, and CLA from January 1st, 2019, to December 31st, 2019. The primary study outcomes were the annualized relapse rate (ARR) and magnetic resonance imaging (MRI) outcome.

MRI activity and extended interval of Natalizumab dosing regimen: a multicentre Italian study.

Background: To minimize the risk of Progressive Multifocal Leukoencephalopathy and rebound in JCV-positive multiple sclerosis (MS) patients after 24 natalizumab doses, it has been proposed to extend the administrations interval. The objective is to evaluate the EID efficacy on MRI activity compared with the standard interval dosing (SID).

Methods: Observational, multicentre, retrospective cohort study, starting from the 24th natalizumab infusion to the loss of follow-up or 2 years after baseline.

Copper deficiency-associated myelopathy in cryptogenic hyperzincemia: a case report.

Copper deficiency syndrome is an underestimated cause of posterior myelitis. We describe the case of a 41-year-old woman, who developed a subacute ataxic paraparesis associated with low back pain. Her 3T spine MRI showed a thin hyperintense FS-Echo T2 longitudinally extensive lesion involving the posterior columns of the cervical cord (from C2 to C6).

Clinical effectiveness of different natalizumab interval dosing schedules in a large Italian population of patients with multiple sclerosis.

Introduction: Natalizumab (NTZ) is one of the most effective treatment options for multiple sclerosis (MS) treatment. Our study aimed to evaluate the effectiveness of NTZ when administered according to the extended dosing strategy compared with standard 4-weekly administration in a large Italian MS population.

Materials And Methods: This retrospective multicentre study included patients with relapsing-remitting MS (RR-MS) who received NTZ administrations between the 1 June 2012 and the 15 May 2018 and were followed by the 'Italian MS Register'.

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.

Neuromyelitis Optica Spectrum Disorder Attack Triggered by Herpes Zoster Infection.

Neuromyelitis optica spectrum disorder is a severe autoimmune disease of the central nervous system characterized by recurrent inflammatory events primarily involving the optic nerves and spinal cord. Recently, a triggering role of infectious events in the development of NMOSD has been suggested. Varicella zoster virus is the most common viral infection involved, though the linkage with anti-aquaporin-4 antibodies is so far unknown.

Five- and seven-year prognostic value of new effectiveness measures (NEDA, MEDA and six-month delayed NEDA) in relapsing-remitting multiple sclerosis.

The concept of 'no evidence of disease activity' (NEDA) has been proposed as a surrogate marker for treatment response in relapsing-remittent multiple sclerosis (MS). However, there is no agreement regarding its prognostic value, nor about the starting time for evaluation of drug effectiveness. Aim of this study was to investigate if the status preservation of two-year NEDA, 'minimal evidence of disease activity' (MEDA) and six-month delayed NEDA (6md-NEDA, with a "rebaseline" six months after the treatment start) predicts the achievement of long-term disability outcomes (EDSS score ≥ 4.

Location of first attack predicts the site of subsequent relapses in multiple sclerosis.

Predictors of attack location in relapsing-remitting multiple sclerosis (RRMS) are poorly known. It has been suggested that the site of the first relapse may influence the location of the subsequents. We aimed to ascertain this hypothesis in a sample of patients consecutively recruited in two Italian MS Centres, with at least two MS attacks.

Efficacy of different rituximab therapeutic strategies in patients with neuromyelitis optica spectrum disorders.

Objective: To evaluate disease activity according to rituximab (RTX) induction and maintenance regimens in a multicenter real-life dataset of NMOSD patients.

Methods: This is an observational-retrospective multicentre study including patients with NMOSD treated with RTX in 21 Italian and 1 Swiss centers. Demographics, relapse rate and adverse events over the follow-up were summarized taking into account induction strategy (two-1 g infusions at a 15-day interval (IND-A) vs.

Treatment of multiple sclerosis with rituximab: A multicentric Italian-Swiss experience.

Background: Rituximab, an anti-CD20 monoclonal antibody leading to B lymphocyte depletion, is increasingly used as an off-label treatment option for multiple sclerosis (MS).

Objective: To investigate the effectiveness and safety of rituximab in relapsing-remitting (RR) and progressive MS.

Methods: This is a multicenter, retrospective study on consecutive MS patients treated off-label with rituximab in 22 Italian and 1 Swiss MS centers.

Spinal cord lesions are frequently asymptomatic in relapsing-remitting multiple sclerosis: a retrospective MRI survey.

Background: Spinal cord (SC) involvement correlates with poor prognosis in patients with multiple sclerosis (MS). Nevertheless, there is no consensus on the use of SC-MRI at follow-up, mainly because of the belief that SC lesions are nearly always symptomatic.

Objectives: The aim of the present study was to investigate the frequency of asymptomatic SC combined unique activity (CUA, new/enlarging T2 or gadolinium-positive [Gd+] lesions) on MRI in a cohort of patients diagnosed with clinically isolated syndrome (CIS) or relapsing-remitting MS (RRMS).

Extending the Interval of Natalizumab Dosing: Is Efficacy Preserved?

Extending the natalizumab interval after the 24th administration could reduce the risk of progressive multifocal leukoencephalopathy (PML). The objective is to evaluate the noninferiority of the efficacy of an extended interval dosing (EID) compared with the standard interval dosing (SID) of natalizumab. It is an observational, multicenter (14 Italian centers), retrospective cohort study, starting from the 24th natalizumab infusion to the loss of follow-up or 2 years after baseline.

The real-world effectiveness of natalizumab and fingolimod in relapsing-remitting multiple sclerosis. An Italian multicentre study.

Background: Both natalizumab and fingolimod are highly effective in the treatment of relapsing-remitting MS (RRMS). In the absence of head-to-head trials, some observational studies have compared their efficacy with conflicting results.

Objectives: To investigate the efficacy of natalizumab and fingolimod in a cohort of RRMS patients in an observational, retrospective study.

Herpes Simplex Virus 1 encephalitis with normal cerebrospinal fluid after brain radiotherapy in a patient with glioblastoma. A case report and review of literature.

Herpes simplex virus encephalitis (HSE) is the most common cause of letal encephalitis and its prevalence appears higher among oncologic patients who undergo brain radiotherapy (RT). We describe a case of 76-year-old woman with glioblastoma multiforme (GBM) who developed HSE shortly after brain RT. Cerebrospinal fluid analysis (CSF) was normal and the diagnosis was driven by brain MRI and EEG.

Successful intravenous immunoglobulin treatment in relapsing MOG-antibody-associated disease.

Treatment of MOG Ab-associated disease is poorly standardized: several drugs have been employed, with variable results. A 50-year-old Caucasian male was admitted to hospital in 2009, with severe acute transverse myelitis. A brain and spinal cord MRI showed multiple demyelinating lesions and cerebrospinal fluid analysis revealed no oligoclonal bands (OCBs).

Correlation between cortical lesions and cognitive impairment in multiple sclerosis.

Objectives: Gray matter (GM) damage is well known as a fundamental aspect of multiple sclerosis (MS). Above all, cortical lesions (CLs) burden, detectable at MRI with double inversion recovery (DIR) sequences, has been demonstrated to correlate with cognitive impairment (CI). The aim of this study was to investigate the role of CLs number in predicting CI in a cohort of patients with MS in a clinical practice setting.

First-line disease-modifying drugs in relapsing-remitting multiple sclerosis: an Italian real-life multicenter study on persistence.

Objective: The introduction of oral disease-modifying drugs (DMDs) in addition to the available, injectable, ones for relapsing-remitting multiple sclerosis (RRMS) could be expected to improve medication persistence due to a greater acceptability of the route of administration. The aim of the study was to compare the proportion of patients discontinuing injectable DMDs (interferon beta 1a/1b, pegylated interferon, glatiramer acetate) with those discontinuing oral DMDs (dimethylfumarate and teriflunomide) during an observation period of at least 12 months. Secondary aims were to compare the time to discontinuation and the reasons for discontinuation between the two groups and to explore the demographic and clinical factors associated with DMD discontinuation.

Definitive childlessness in women with multiple sclerosis: a multicenter study.

The frequency of definitive childlessness in women with multiple sclerosis (MS) may be higher than in the general population. MS may also affect decisions on the delivery procedure and on breast-feeding issues. Aim of the study was to assess the frequency of childlessness and its possible causes, the proportion of cesarean deliveries (CD), and the frequency of breast-feeding in patients and controls who have reached the end of their reproductive period.

Previous treatment influences fingolimod efficacy in relapsing-remitting multiple sclerosis: results from an observational study.

Objective: Fingolimod (FTY) is licensed as a disease-modifying treatment in highly active relapsing-remitting multiple sclerosis. The aim of the study was to evaluate the efficacy and safety of FTY in a real-life setting and to explore the possible role of clinical and MRI parameters, including previous treatment type, in predicting its efficacy.

Methods: Clinical and MRI data was collected on 127 patients assigned to treatment with FTY in six multiple sclerosis centers in Emilia-Romagna, Italy, between August 2011 and June 2013.
