Therapeutics of neuroinflammatory disorders including multiple sclerosis is one of the fastest growing areas in neurology. However, pressures on higher specialty training in neurology together with an expanding curriculum have led to challenges in adequately preparing trainees for a subspecialist career. In this study we set out to understand current perceptions and barriers to training in neuroinflammatory disorders among neurology trainees in the UK.

The Association of British Neurologists last published guidelines on disease-modifying treatment (DMT) in multiple sclerosis (MS) in 2015. Since then, additional DMTs have been licensed and approved for prescribing within the National Health Service for relapsing-remitting MS, early primary progressive MS and active secondary progressive MS. This updated guidance provides a consensus-based approach to using DMTs.

Introduction: There remains a high unmet need for disease-modifying therapies that can impact disability progression in secondary progressive multiple sclerosis (SPMS). Following positive results of the phase 2 MS-STAT study, the MS-STAT2 phase 3 trial will evaluate the efficacy and cost-effectiveness of repurposed high-dose simvastatin in slowing the progression of disability in SPMS.

Methods And Analysis: MS-STAT2 will be a multicentre, randomised, placebo-controlled, double-blind trial of participants aged between 25 and 65 (inclusive) who have SPMS with an Expanded Disability Status Scale (EDSS) score of 4.

Background: Cladribine is an oral disease-modifying drug approved for the treatment of highly active relapsing multiple sclerosis (MS). The recommended number of treatment courses is two, with the courses given 1 year apart (i.e.

Background: Highly active (HA) relapsing remitting multiple sclerosis (RRMS) is associated with frequent relapses and high burden of disease/disability. Natalizumab is licensed for HA RRMS, including rapidly evolving severe (RES) (≥2 relapses in previous year) and sub-optimally treated (SOT) (≥1 relapse in previous year despite treatment) populations. However, there is limited RCT evidence in the SOT subpopulation.

Article Synopsis
  • - The study aimed to analyze real-world treatment persistence rates of disease-modifying therapies (DMTs) for individuals with multiple sclerosis (MS), examining factors that lead to discontinuation of these treatments.
  • - Data from 4,366 patients with relapse-onset MS were collected from 13 specialist centers in the UK, finding a median persistence of 4.3 years on any DMT, with adverse events and lack of efficacy being the top reasons for stopping treatment.
  • - Results indicated that immune reconstituting therapies like alemtuzumab may provide more prolonged DMT options compared to traditional therapies, emphasizing the importance of understanding DMT persistence for better treatment strategies.

Background: The decision of initiating treatment for multiple sclerosis (MS) with a high-efficacy DMT (HE DMT) or non-high-efficacy DMT (non-HE DMT) is influenced by several factors, including risk perception of patients and physicians.

Objective: Investigate the influence of physicians' risk perception on decision-making when switching treatments for MS and the reasons for switching.

Methods: Data were drawn from the Adelphi Real-World MS Disease-Specific Program (a retrospective survey) and analysis included people with RMS identified between 2017- 2021.

Background: Annualized relapse rate (ARR) is used as an outcome measure in multiple sclerosis (MS) clinical trials. Previous studies demonstrated that ARR has reduced in placebo groups between 1990 and 2012. This study aimed to estimate real-world ARRs from contemporary MS clinics in the UK, in order to improve the feasibility estimations for clinical trials and facilitate MS service planning.

Purpose: Genetic studies of multiple sclerosis (MS) susceptibility and severity have focused on populations of European ancestry. Studying MS genetics in other ancestral groups is necessary to determine the generalisability of these findings. The genetic Association study in individuals from Diverse Ancestral backgrounds with Multiple Sclerosis (ADAMS) project aims to gather genetic and phenotypic data on a large cohort of ancestrally-diverse individuals with MS living in the UK.

Food and drink are a key part of our lives. While Virtual Reality has the potential to provide high-fidelity simulation of real experiences in virtual worlds, the incorporation of flavor appreciation within these virtual experiences has largely been ignored. This paper introduces a virtual flavor device to simulate real flavor experiences.

Objectives: Whether the effects of therapies may wane over time is a matter of debate, especially when considering their long-term cost-effectiveness. Here, we examined how the assumption of the waning of treatment effect was applied across the National Institute for Health and Care Excellence (NICE) appraisals for disease-modifying therapies (DMTs) used in multiple sclerosis.

Methods: We undertook a document analysis following a search of the NICE website.

Introduction: Neurosarcoidosis is associated with a significant degree of morbidity and mortality and its treatments are varied and complex. There is a paucity of information in current literature on patterns of treatment and long term outcomes. This study aimed to evaluate the clinical outcomes and responses to immunosuppressive therapy in a large cohort of neurosarcoidosis patients .

Objective: To characterize a cohort of patients with neurosarcoidosis with particular focus on CSF analysis and to investigate whether CSF values could help in distinguishing it from multiple sclerosis (MS).

Methods: This retrospective cohort study enrolled 85 patients with a diagnosis of neurosarcoidosis (possible, probable, or definite). CSF total protein, white cell count, and angiotensin-converting enzyme levels were measured.

Neurodegeneration is the main cause for permanent disability in multiple sclerosis. The effect of current immunomodulatory treatments on neurodegeneration is insufficient. Therefore, direct neuroprotection and myeloprotection remain an important therapeutic goal.

Article Synopsis
  • The study introduces mcDESPOT, an advanced technique for measuring T(1) and T(2) relaxation times in the brain, enhancing traditional methods by allowing for multicomponent analysis.
  • This new approach addresses the limitation of earlier methods, which assumed a single-component relaxation and struggled with the complexities found in biological tissues like human white and gray matter.
  • The results from testing mcDESPOT on healthy individuals and MS patients suggest its potential for evaluating tissue changes related to neurodegenerative diseases within clinically feasible timeframes of 16 to 30 minutes.
