Serum neurofilament light chain and glial fibrillary acidic protein for predicting response to apheresis in steroid-refractory multiple sclerosis relapses. Eur J Neurol 2024; 31:e16323. [PMID: 38700322 DOI: 10.1111/ene.16323] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Revised: 04/11/2024] [Accepted: 04/12/2024] [Indexed: 05/05/2024]
Abstract
BACKGROUND AND PURPOSE The predictive value of serum neurofilament light chain (sNfL) and serum glial fibrillary acidic protein (sGFAP) for apheresis outcome in steroid-refractory multiple sclerosis (MS) relapse has not yet been evaluated. METHODS We used pre- and postapheresis serum samples from 38 participants of the IAPEMS trial (clinicaltrials.gov: NCT02671682), which investigated the use of immunoadsorption versus plasma exchange for the treatment of steroid-refractory MS attacks. Response to apheresis was classified based on improvement on (i) the Expanded Disability Status Scale (EDSS), (ii) the affected functional system scores (FSS) of the EDSS, or (iii) the visual acuity for patients with optic neuritis, 4 weeks postapheresis. sNFL and sGFAP were measured by single molecule arrays. RESULTS Preprocedural sGFAP levels could discriminate between responders and nonresponders, determined by FSS improvement (p = 0.017). In multivariate logistic regression analysis, younger age (odds ratio [OR] = 0.781, 95% confidence interval [CI] = 0.635-0.962, p = 0.020) and lower sGFAP levels (OR = 0.948, 95% CI = 0.903-0.995, p = 0.031) could predict response to apheresis in the overall cohort. We could observe a trend towards a favourable apheresis outcome with higher sNfL levels (OR = 1.413, 95% CI = 0.965-2.069, p = 0.076). Analysis of the sNfL-to-sGFAP ratio showed an OR of 1.924 (95% CI = 1.073-3.451, p = 0.028) for predicting apheresis response. The ratio showed a better predictive value than the individual parameters. Neither biomarker was affected by the number of steroid cycles preapheresis. CONCLUSIONS Lower sGFAP levels, a higher sNfL-to-sGFAP ratio, and younger age are associated with a favourable apheresis outcome.

Abstract
Objective Intravenous methylprednisolone is the standard treatment for a multiple sclerosis relapse; however, this fails to improve symptoms in up to one quarter of patients. Immunoadsorption is an accepted treatment for refractory relapses, but prospective comparator-controlled studies are missing. Methods In this observational study, patients with steroid-refractory acute multiple sclerosis relapses receiving either six courses of tryptophan-immunoadsorption or double-dose methylprednisolone therapy were analysed. Outcomes were evaluated at discharge and three months later. Immune profiling of blood lymphocytes and proteomic analysis were performed by multi-parameter flow cytometry and Olink analysis, respectively (NCT04450030). Results 42 patients were enrolled (methylprednisolone: 26 patients; immunoadsorption: 16 patients). For determination of the primary outcome, treatment response was stratified according to relative function system score changes (“full/best” vs. “average” vs. “worse/none”). Upon discharge, the adjusted odds ratio for any treatment response (“full/best” + ”average” vs. “worse/none”) was 10.697 favouring immunoadsorption (p = 0.005 compared to methylprednisolone). At follow-up, the adjusted odds ratio for the best treatment response (“full/best” vs. “average” + ”worse/none”) was 103.236 favouring IA patients (p = 0.001 compared to methylprednisolone). Similar results were observed regarding evoked potentials and quality of life outcomes, as well as serum neurofilament light-chain levels. Flow cytometry revealed a profound reduction of B cell subsets following immunoadsorption, which was closely correlated to clinical outcomes, whereas methylprednisolone had a minimal effect on B cell populations. Immunoadsorption treatment skewed the blood cytokine network, reduced levels of B cell-related cytokines and reduced immunoglobulin levels as well as levels of certain coagulation factors. Interpretation Immunoadsorption demonstrated favourable outcomes compared to double-dose methylprednisolone. Outcome differences were significant at discharge and follow-up. Further analyses identified modulation of B cell function as a potential mechanism of action for immunoadsorption, as reduction of B cell subsets correlated with clinical improvement.

Neurol Sci 2022; 43:4933-4944. [PMID: 35420360 PMCID: PMC9349140 DOI: 10.1007/s10072-022-06022-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2021] [Accepted: 03/16/2022] [Indexed: 12/03/2022]
Abstract
Background Multiple sclerosis (MS) accounts for 176 cases per 100,000 inhabitants (female/male ratio = 2:1) in Italy. For most of the patients (67%), the disease course is relapsing–remitting MS (RRMS). Objective To compare the costs and quality-adjusted life years (QALYs) of teriflunomide in RRMS naïve patients vs. RRMS patients previously treated (experienced) with other disease-modifying therapies in Italy. Methods A four health states Markov model-supported cost-utility analysis (CUA) covering a 7-year timespan through annual cycles was developed, following the healthcare sector and the societal viewpoints. Part of the parameters that populated the Markov model was obtained from a questionnaire administered to four primary Italian MS centres. Costs of healthcare and non-healthcare resources, expressed in euro (€) 2019, and QALYs were discounted at 3% real social discount rate. One-way, scenario and probabilistic sensitivity analyses tested the uncertainty of the baseline findings. Results Baseline CUA shows that teriflunomide in RRMS naïve patients is strongly dominant vs. experienced patients (healthcare sector perspective: − €1042.68 and + 0.480 QALYs; societal perspective: − €6782.81 and + 0.480 QALYs). Sensitivity analyses confirmed the robustness of the baseline results. Conclusion Teriflunomide in RRMS naïve vs. experienced patients is cost-effective and possibly strongly dominant from both the healthcare sector and the society viewpoints in Italy. Our findings need further confirmation from real-world studies. Supplementary Information The online version contains supplementary material available at 10.1007/s10072-022-06022-x.

Abstract
Therapeutic plasma exchange (TPE) is an effective and affordable treatment option in most parts of Southeast Asia (SEA). In 2018, the SEA TPE Consortium (SEATPEC) was established, consisting of regional neurologists working to improve outcome of various autoimmune neurological diseases. We proposed an immunotherapeutic guideline prioritizing TPE for this region. We reviewed disease burden, evidence-based treatment options, and major guidelines for common autoimmune neurological disorders seen in SEA. A modified treatment algorithm based on consensus agreement by key-opinion leaders was proposed. Autoimmune antibody diagnostic testing through collaboration with accredited laboratories was established. Choice of first-line immunotherapies (IVIg/corticosteroid/TPE) is based on available evidence, clinicians’ experience, contraindications, local availability, and affordability. TPE could be chosen as first-line therapy for GBS, CIDP, MG (acute/short term), IgG, A paraproteinemic neuropathy, and NMDAR encephalitis. Treatment is stopped for acute monophasic conditions such as GBS and ADEM following satisfactory outcome. For chronic immune disorders, a therapy taper or long-term maintenance therapy is recommended depending on the defined clinical state. TPE as second-line treatment is indicated for IVIg or corticosteroids refractory cases of ADEM, NMOSD (acute), MG, and NMDAR/LGI1/CASPR2/Hashimoto’s encephalitis. With better diagnosis, treatment initiation with TPE is a sustainable and effective immunotherapy for autoimmune neurological diseases in SEA.

Abstract
Background Treatments for multiple sclerosis (MS) relapse include intravenous corticosteroids and repository corticotropin injection. Despite available treatment, in the Multiple Sclerosis in America 2017 survey, only 47% of patients reported always/often contacting their MS health care provider (HCP) during relapse. In this study, the Multiple Sclerosis in America 2017 survey participants who received intravenous corticosteroids or repository corticotropin injection for treatment of past relapses completed a follow-up survey to understand how patients characterize relapse severity and to explore predictors of patients contacting their HCP during a relapse. Methods Patients were 18 years and older, diagnosed as having MS by an HCP, and currently using disease-modifying therapy. Patients completed an online survey assessing relapse characteristics and interactions with the HCP treating the patient's MS. Regression analysis identified predictors of patients contacting their HCP during relapse. Results Mean age of the 126 respondents was 49.2 years, 81.0% were female, and most (80.2%) had one or more relapses in the past 2 years. Patients estimated that 38.3% of their relapses were mild; 45.1%, moderate; and 16.6%, severe. Number and frequency of symptoms increased with relapse severity. Less than half (46.0%) reported they were extremely likely to contact their HCP during a relapse. The best predictors of being likely to contact the HCP during relapse were the HCP having previously discussed the importance of immediately communicating a relapse and patients' willingness to accept the HCP's recommendation for relapse treatment. Conclusions Findings highlight the importance of HCPs' advance discussions with patients with MS regarding relapse management to increase the likelihood patients will contact their HCP during relapse.

Abstract
INTRODUCTION Therapeutic plasma exchange (TPE) is considered a treatment option for steroid-refractory multiple sclerosis (MS) relapses. Our objective was to assess long-term clinical response to TPE in MS steroid-refractory exacerbations. METHODS Retrospective study of relapsing remitting MS (RRMS) patients presenting intravenous methylprednisolone (IVMPS)-refractory relapses, who underwent TPE. Response to TPE was assessed at 1, 3, 6, 12 and 24-months post-treatment, and compared to a second group of RRMS patients with similar demographic and clinical characteristics presenting, IVMPS-refractory relapses but not treated with TPE. Multivariate regression analysis was used to assess potential predictors of significant clinical response. RESULTS Between 2011 to 2020, a total of 23 RRMS patients were treated with TPE. Twenty-one patients not receiving the treatment served as controls. No differences in demographic or clinical characteristics, or predictors of clinical improvement after TPE were detected between groups. Seventy-eight percent of patients treated with TPE presented clinical improvement at 24 months. TPE-treated patients presented lower EDSS scores at 6 and at 24 months. Younger age, presence of gadolinium-enhancing lesions and TPE treatment were associated with better clinical outcomes. No life-threatening side effects were reported. CONCLUSIONS TPE is a safe and well tolerated procedure that decreases long-term disability in RRMS patients with IVMPS-refractory relapses.

Abstract
Diagnostic accuracy is poor in demyelinating myelopathies, and therefore a challenge for neurologists in daily practice, mainly because of the multiple underlying pathophysiologic mechanisms involved in each subtype. A systematic diagnostic approach combining data from the clinical setting and presentation with magnetic resonance imaging (MRI) lesion patterns, cerebrospinal fluid (CSF) findings, and autoantibody markers can help to better distinguish between subtypes. In this review, we describe spinal cord involvement, and summarize clinical findings, MRI and diagnostic characteristics, as well as treatment options and prognostic implications in different demyelinating disorders including: multiple sclerosis (MS), neuromyelitis optica spectrum disorder, acute disseminated encephalomyelitis, anti-myelin oligodendrocyte glycoprotein antibody-associated disease, and glial fibrillary acidic protein IgG-associated disease. Thorough understanding of individual case etiology is crucial, not only to provide valuable prognostic information on whether the disorder is likely to relapse, but also to make therapeutic decision-making easier and reduce treatment failures which may lead to new relapses and long-term disability. Identifying patients with monophasic disease who may only require acute management, symptomatic treatment, and subsequent rehabilitation, rather than immunosuppression, is also important.

Abstract
PURPOSE OF REVIEW This article provides an overview of the clinical and pathologic features of multiple sclerosis (MS) relapses and reviews evidence-based approaches to their treatment. RECENT FINDINGS Despite the increasing number and potency of MS treatments, relapses remain one of the more unpredictable and disconcerting disease aspects for many patients with MS, making their accurate recognition and treatment an essential component of good clinical care. The expanding range of relapse treatments now includes oral corticosteroids, comparable in efficacy to IV methylprednisolone at a fraction of the cost. While this development improves access to prompt treatment, it also underscores the importance of recognizing mimics of MS relapses to reduce corticosteroid overuse and its attendant risks. SUMMARY Like MS itself, MS relapse remains primarily a clinical diagnosis. The treatment options for MS relapse include corticosteroids, adrenocorticotropic hormone (ACTH), plasma exchange, and rehabilitation, used singly or sequentially, with the goal of limiting the duration and impact of associated disability. Even when treated promptly and effectively, clinical or subclinical sequelae of MS relapses frequently remain.

Abstract
Intravenous methyl prednisolone (IVMPS) represents the standard of care for multiple sclerosis (MS) relapses, but fail to improve symptoms in one quarter of patients. In this regard, apart from extending steroid treatment to a higher dose, therapeutic plasma exchange (TPE) has been recognized as a treatment option. The aim of this retrospective, monocentric study was to investigate the efficacy of TPE versus escalated dosages of IVMPS in refractory MS relapses. An in-depth medical chart review was performed to identify patients from local databases. Relapse recovery was stratified as “good/full”, “average” and “worst/no” according to function score development. In total, 145 patients were analyzed. Good/average/worst recovery at discharge was observed in 60.9%/32.6%/6.5% of TPE versus 15.2%/14.1%/70.7% of IVMPS patients, respectively. A total of 53.5% of IVMPS patients received TPE as rescue treatment and 54.8% then responded satisfactorily. The multivariable odds ratio (OR) for worst/no recovery was 39.01 (95%–CI: 10.41–146.18; p ≤ 0.001), favoring administration of TPE as first escalation treatment. The effects were sustained at three-month follow-ups, as OR for further deterioration was 6.48 (95%–CI: 2.48–16.89; p ≤ 0.001), favoring TPE. In conclusion, TPE was superior over IVMPS in the amelioration of relapse symptoms at discharge and follow-up. This study provides class IV evidence supporting the administration of TPE as the first escalation treatment to steroid-refractory MS relapses.

Abstract
INTRODUCTION Timely and effective resolution of multiple sclerosis (MS) relapse is critical to minimizing residual deficits, which can result in neurologic disability. Oral corticosteroids (OCS) and intravenous corticosteroids [intravenous methylprednisolone (IVMP)] are earlier line treatments; alternatives include repository corticotropin injection (RCI; H.P. Acthar® Gel), plasmapheresis (PMP), and intravenous immunoglobulin (IVIG). Contemporary insight into the use of relapse treatments and their effectiveness is needed. OBJECTIVE To evaluate relapse rates, frequency of treatments used, and treatment effectiveness (i.e., relapse resolution). METHODS A retrospective analysis of patients ages 18-89 years experiencing MS relapse from 1 January 2008 to 30 June 2015 was conducted using administrative claims data. MS relapse was defined based on established claims-based methodology. The first claim for relapse treatment (i.e., prescription or administration) was used to designate the treatment group and relapse date, respectively. Relapses occurring ≤ 30 days were considered an episode. The first relapse episode was identified for every patient. Treatment was deemed effective in resolving the relapse if no additional relapses followed within the episode; otherwise, the relapse was considered unresolved. A 5-day OCS taper following IVMP administration, designated IVMP ± OCS, was allowed. Relapse frequency, treatment use, and relapse resolution were quantified. Relapse resolution was likewise evaluated in patients continuously enrolled for 12 months before and after first treatment with RCI or PMP/IVIG, with PMP/IVIG administrations within 7 days of each other being considered a single course of therapy. RESULTS During the study period, 9574 patients experienced ≥ 1 relapse; 26.0% of patients had ≥ 2 relapses/year. The mean number of relapse episodes was 2.6 over a mean follow-up of 2.7 years for an annualized relapse rate of 1.0. Corticosteroids were the first treatment used in 90.4% of relapses (OCS = 51.8%, IVMP = 38.6%), followed by IVIG (6.0%), RCI (2.2%) and PMP (1.5%). The proportion of patients achieving relapse resolution with their first treatment was 90.5% with OCS (n = 5710), 47.8% with IVMP ± OCS (n = 3425), 96.9% with RCI (n = 195), 50.7% with PMP (n = 73), and 43.9% with IVIG (n = 171). Among continuously enrolled patients (n = 373), relapse resolution was 95.7% with RCI (n = 232) and 66.0% with PMP/IVIG (n = 141); significant cohort differences were observed. CONCLUSIONS As demonstrated in other studies, OCS were generally effective. However, real-world effectiveness varied with other treatments. Relapse resolution of the first treatment with OCS was higher than with IVMP ± OCS; similarly, relapse resolution was higher with RCI as the first treatment than with PMP/IVIG. Results demonstrate RCI's effectiveness in appropriate patients. Limitations pertaining to claims-based research apply. FUNDING Mallinckrodt Pharmaceuticals (Bedminster, NJ).

Abstract
The American Society for Apheresis (ASFA) Journal of Clinical Apheresis (JCA) Special Issue Writing Committee is charged with reviewing, updating and categorizing indications for the evidence-based use of therapeutic apheresis (TA) in human disease. Since the 2007 JCA Special Issue (Fourth Edition), the committee has incorporated systematic review and evidence-based approaches in the grading and categorization of apheresis indications. This Eighth Edition of the JCA Special Issue continues to maintain this methodology and rigor in order to make recommendations on the use of apheresis in a wide variety of diseases/conditions. The JCA Eighth Edition, like its predecessor, continues to apply the category and grading system definitions in fact sheets. The general layout and concept of a fact sheet that was introduced in the Fourth Edition, has largely been maintained in this edition. Each fact sheet succinctly summarizes the evidence for the use of TA in a specific disease entity or medical condition. The Eighth Edition comprises 84 fact sheets for relevant diseases and medical conditions, with 157 graded and categorized indications and/or TA modalities. The Eighth Edition of the JCA Special Issue seeks to continue to serve as a key resource that guides the utilization of TA in the treatment of human disease.

Impact of delayed treatment on exacerbations of multiple sclerosis among Puerto Rican patients. Surg Neurol Int 2019; 10:200. [PMID: 31768280 PMCID: PMC6826276 DOI: 10.25259/sni_252_2019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2019] [Accepted: 08/26/2019] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND There are limited data on multiple sclerosis (MS) patients in underserved groups, including Puerto Rico. In this study, we analyzed the characteristic of MS symptoms and number of relapses in Puerto Rican patients. We then compare these characteristics with MS patients from the US. The number of MS relapses is highly correlated with the treatment onset and adherence. Patients in Puerto Rico have been experiencing lengthy treatment delay. We will discuss the possible causes of such delay and its impact on MS prognosis. METHODS This retrospective cohort study consisted of the evaluation of 325 medical records from MS patients attending the Caribbean Neurological Center from 2014 to 2019. We gathered symptoms and comorbidities data as binary objects. The treatment delay was calculated based on the mean value of days between diagnosis and treatment onset for these groups of patients. RESULTS We found that on average, the treatment delay for MS patients in Puerto Rico (PR) to receive their medication was 120 days. The most common MS subtype was relapsing-remitting 72.8%, with a mean of 1.684 relapses per year. Initial symptoms were sensory 54%, visual 33.1%, motor 28.8%, coordination 23.2%, fatigue 9.7%, memory 7.3%, depression 6.5%, urinary 4.9%, gastrointestinal 2.4%, and sexual dysfunction 1.6%. The most common comorbidities were hypertension 18.4%, asthma 13.6%, and thyroid disease 12.8%. When we compared the comorbidities between the two populations, immune thrombocytopenia had the highest percent change with the value of almost 200% (0.001% of US patient vs. 0.8% of Puerto Rican MS patients). CONCLUSION Patients from Puerto Rico had a 33% higher relapse rate compared to the one reported for MS patients in the US. This higher rate may be related to the long delay in receiving their medications. They also had a higher rate of complex comorbidities such as immune thrombocytopenia or thyroid disease. Our findings provide a proof of concept that delay in receiving medications can increase the number of relapses and complex comorbidities among MS patients.

Abstract
Multiple sclerosis (MS) is the most abundant inflammatory demyelinating disorder of the central nervous system. Despite recent advances in its long-term immunomodulatory treatment, MS patients still suffer from relapses, significantly contributing to disability accrual. In recent years, apheresis procedures such as therapeutic plasma exchange (TPE) and immunoadsorption (IA) have been recognized as two options for treating MS relapses, that do not respond to standard treatment with corticosteroids. TPE is already incorporated in most international guidelines, although evidence for its use resulted mostly from either case series or small unblinded and/or non-randomized trials. Data on IA are still sparse, but several studies indicate comparable efficacy between both apheresis procedures. This article gives an overview of the published evidence on TPE and IA in the treatment of acute relapses in MS. Further, we outline current evidence regarding individual outcome predictors, describe technical details of apheresis procedures, and discuss apheresis treatment in children and during pregnancy.

Efficacy, safety, and quality-of-life of treatments for acute relapses of multiple sclerosis: results from a literature review of randomized controlled trials. Degener Neurol Neuromuscul Dis 2019; 9:55-78.

Abstract
Background Intravenous methylprednisolone (IVMP), repository corticotropin injection (RCI), plasmapheresis (PMP), and intravenous immunoglobulin (IVIG) are used in the treatment of acute multiple sclerosis (MS) relapse. A systematic literature review (SLR) of randomized controlled trials (RCTs) was conducted to examine the highest quality evidence available for these therapies. Methods English-language articles were searched in MEDLINE, Embase, and Cochrane Library through May 2016 per Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards. MS conferences, SLRs, and bibliographies of included studies were also searched. Eligible studies included adults treated with ≥1 aforementioned therapy. Results Twenty-three RCTs were identified: 22 on efficacy, 11 on safety, and 3 on QOL (ie 18 IVMP, 2 RCI, 2 PMP, and 2 IVIG). IVMP and RCI improved relapse-related disability; however, IVIG and PMP showed inconsistent efficacy. QOL data were only ascertained for IVMP. Conclusions RCTs indicate IVMP and RCI are efficacious and well tolerated treatments for MS relapse. Overall, many RCTs were dated, with sample sizes of fewer than 30 patients and no definitions for relapse nor clinically significant change. Contemporary evidence generation for all relapse treatments of interest, across efficacy, safety, and QOL outcomes, is still needed.

Abstract
OBJECTIVE To investigate the potential relationship between the human leukocyte antigen (HLA) type (class I and II) and the response to several disease-modifying therapies (DMTs) in patients with multiple sclerosis (MS). METHODS We analyzed clinical data of 87 patients with MS at the beginning and end of each type of DMT including the disease duration, Expanded Disability Status Scale and Multiple Sclerosis Severity Score (MSSS). Genotyping of HLA-DRB1, HLA-DPB1, HLA-DQB1, HLA-A, HLA-B and HLA-C alleles were identified using high-resolution techniques. Statistical correlation between the HLA type and response to DMTs was done using the initial and final MSSS. RESULTS Statistical relationships (p < 0.05) were found for only 15 of 245 alleles tested. There was a reduction in the MSSS for patients treated with corticosteroids (DRB1*15:01, DPB1*04:01, DQB1*02:01 and DQB1*03:01), azathioprine (DRB1*03:01, DPB1*04:01, DQB1*03:02, DQB1*06:02, HLA-C*07:02), interferon β-1a 22 mcg (DRB1*11:04, DQB1*03:01 and DQB1*03:02), interferon β-1a 30 mcg (DPB1*02:01, HLA-C*05:01) and interferon β-1b (DQB1*02:01). CONCLUSION These findings suggest a few relationships between the HLA and response to DMTs in the disability for some types of HLA class I and II alleles in a specific subset of MS patients.

Abstract
Multiple sclerosis (MS) is a chronic inflammatory disease with demyelination of the central nervous system. High-dosage corticosteroids are the first-line therapy in the acute relapsing of MS. We report a case of severe high-dose methylprednisolone-induced acute hepatitis in a patient with a new diagnosis of MS. A 16-year-old girl was admitted for urticaria, angioedema, nausea and vomiting a month later she had been diagnosed with MS and treated with high-dosage methylprednisolone. Laboratory investigations showed hepatic insufficiency with grossly elevated liver enzymes. A liver biopsy showed focal centrilobular hepatocyte necrosis with interface hepatitis. Methylprednisolone-induced hepatotoxicity can confuse the clinical picture of patients with MS and complicate the differential diagnosis. We believe that each specialist should know it and monitor patients with MS taking high doses of methylprednisolone. As there is no screening model that predicts idiosyncratic hepatotoxicity, we promote screening for potential liver injury following pulse steroid therapy.

Abstract
Multiple sclerosis continues to be a challenging and disabling condition but there is now greater understanding of the underlying genetic and environmental factors that drive the condition, including low vitamin D levels, cigarette smoking, and obesity. Early and accurate diagnosis is crucial and is supported by diagnostic criteria, incorporating imaging and spinal fluid abnormalities for those presenting with a clinically isolated syndrome. Importantly, there is an extensive therapeutic armamentarium, both oral and by infusion, for those with the relapsing remitting form of the disease. Careful consideration is required when choosing the correct treatment, balancing the side-effect profile with efficacy and escalating as clinically appropriate. This move towards more personalised medicine is supported by a clinical guideline published in 2018. Finally, a comprehensive management programme is strongly recommended for all patients with multiple sclerosis, enhancing health-related quality of life through advocating wellness, addressing aggravating factors, and managing comorbidities. The greatest remaining challenge for multiple sclerosis is the development of treatments incorporating neuroprotection and remyelination to treat and ultimately prevent the disabling, progressive forms of the condition.
