Probst Y, Kinnane E. Quality of reporting health behaviors for multiple sclerosis (QuoRH-MS): A scoping review to inform intervention planning and improve consistency of reporting. Brain Behav 2024; 14:e3635. [PMID: 39148370 PMCID: PMC11327400 DOI: 10.1002/brb3.3635] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Revised: 05/26/2024] [Accepted: 07/03/2024] [Indexed: 08/17/2024] Open
Abstract
BACKGROUND Multiple sclerosis (MS) is a neurological condition that necessitates a multidisciplinary approach to aid those living with MS in managing their disease. Health behavior, or lifestyle modification, is an emerging approach to MS self-management. MS researchers utilize measurement tools to ensure that interventions are best suited to the outcomes, thereby potentially influencing practice. The aim of this study was to investigate which tools are being used for health behavior management studies in people living with MS and develop an aid for tool selection. METHODS A scoping review guided by the PRISMA-Sc checklist and the JBI manual for evidence synthesis was employed with a systematic search strategy executed across four scientific databases: Medline, PubMed, CINAHL, and Cochrane Libraries. The types of assessment tools used were extracted from the included studies. Each tool was categorized into the health behavior intervention discipline (nutrition, exercise, and psychology) and then subcategorized by the tool's purpose. The frequency of use was determined for each tool. Reporting of validation of the assessment tools were collated to inform a tool selection checklist. RESULTS The review identified a total of 248 tools (12 nutrition, 55 exercise, and 119 psychology unique reports) from 166 studies. Seventy-seven multidimensional tools were identified including measures of quality of life, fatigue, and functional scales. Only 88 studies (53%) referred to the validity of the tools. The most commonly reported tools were the dietary habits questionnaire (n = 4, nutrition), 6-minute walk test (n = 17, exercise), Symbol Digits and Modalities Test, and Hospital Anxiety and Depression Scale (n = 15 each, psychology) with the Expanded Disability Status Scale reported 43 times. CONCLUSION Evidence from interventions may inform practice for health professionals. This review provides insights into the range of tools reported across health behavior intervention studies for MS and offers a guide toward more consistent reporting of study methods.

Associations between diet and disease progression and symptomatology in multiple sclerosis: A systematic review of observational studies. Mult Scler Relat Disord 2024; 87:105636. [PMID: 38678968 DOI: 10.1016/j.msard.2024.105636] [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: 03/06/2024] [Revised: 04/12/2024] [Accepted: 04/15/2024] [Indexed: 05/01/2024]
Abstract
BACKGROUND Although many people with MS (pwMS) modify their diet after diagnosis, there is still no consensus on dietary recommendations for pwMS. A number of observational studies have explored associations of diet and MS progression, but no studies have systematically reviewed the evidence. This systematic review aimed to provide an objective synthesis of the evidence for associations between diet and MS progression, including symptoms and clinical outcomes from observational studies. METHODS We performed a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Electronic database searches were performed for studies completed up to 26 July 2023 using PubMed (Medline), Web of Science, CINAHL, Embase (Ovid), and Scopus, followed by citation and reference list checking. We included studies using diet quality scores or dietary indices. Studies assessing individual foods, nutrients, or dietary supplements were excluded. We used the Newcastle-Ottawa Scale to assess the risk of bias of included studies. RESULTS Thirty-two studies met the inclusion criteria. Of these, 20 were cross-sectional and 12 prospective. The most frequent outcomes assessed were disability (n = 19), quality of life (n = 12), fatigue (n = 12), depression (n = 9), relapse (n = 8), anxiety (n = 3), and magnetic resonance imaging (MRI) outcomes (n = 4). Based on prospective studies, this review suggests that diet might be associated with quality of life and disability. There were also potential effects of higher diet quality scores on improved fatigue, disability, depression, anxiety, and MRI outcomes but more evidence is needed from prospective studies. CONCLUSIONS Observational studies show some evidence for an association between diet and MS symptoms, particularly quality of life and disability. However, the impact of diet on other MS outcomes remains inconclusive. Ultimately, our findings suggest more evidence is needed from prospective studies and well-designed tailored intervention studies to confirm associations.

Abstract
BACKGROUND AND PURPOSE Research promoting the health of the brain has increased exponentially over the last decade. The importance of 'brain health' for multiple sclerosis (MS), as one example, is a high priority. However, as research into the concept increases, so does varied use of the term. METHODS A scoping review, guided by the methodological framework of the Joanna Briggs Institute, was conducted to collate the evidence relating to brain health for MS. A comprehensive literature search incorporated six search strategies to retrieve both scientific and grey literature sources. All evidence sources were qualitatively charted and synthesized (meta-synthesis) according to their definition of brain health used, outcome measures and brain-healthy lifestyle elements. RESULTS Seventy evidence sources (34 peer reviewed, 36 grey literature) were eligible for inclusion. Of these, just over half (n = 40, 57%) provided a definition of brain health. The most common definition alluded to the biomedical model of neurological reserve (n = 22, 55%), a self-remodelling theory described to retain optimal brain function. Twenty-nine outcome measures of brain health were identified, the most frequent being magnetic resonance imaging metrics (n = 25, 83%). Physical activity was the most prevalent brain-healthy lifestyle element (n = 44), followed by avoidance of smoking (n = 26) and diet (n = 24). CONCLUSIONS Brain health should be considered a primary target for optimal disease and lifestyle management across the MS disease course. A working definition reflecting a shift from a medical lens towards broader biopsychosocial contexts that may influence brain health for people living with MS is proposed.

[PMID: 38576113 PMCID: PMC10995448 DOI: 10.1111/hex.14042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 03/17/2024] [Accepted: 03/23/2024] [Indexed: 04/06/2024] Open
Abstract
INTRODUCTION Healthcare professionals have an important role in advocating for the adoption of a brain-healthy lifestyle for optimal multiple sclerosis (MS) care. Nonetheless, studies to date have mainly focussed on the consumer perspective. Herein, we aimed to explore the current practices of how healthcare professionals support protective, lifestyle-related behaviour changes to optimise brain health among people living with MS (plwMS), and their perspectives of professional roles. METHODS Australian healthcare professionals were recruited via study advertisements, purposive and snowball sampling, to participate in an online, semi-structured and audio-recorded interview. Clinicians were eligible if they had a minimum of a tertiary Bachelor's degree and 12-months experience working with plwMS, access to the Internet and sufficient time to participant. An inductive, data-driven form of reflexive thematic analysis was undertaken before thematic categorisation of the quotes from transcripts. Data analysis was guided by the methods of Braun and Clark and the study's underpinnings drew on the constructs of the Social Cognitive Theory (SCT). RESULTS Six physicians, 10 MS nurses, 18 allied health professionals, one exercise therapist and one alternative therapist were interviewed. Three primary themes encompassing the perceived role of healthcare professionals in supporting a brain-healthy lifestyle were identified: (1) the empowering role, (2) collaborative role and (3) communicative role. External factors/forces including time constraints, professional expertise, training and skill set, power dynamics, consumer readiness, health literacy, self-efficacy and motivation are at play, and affect how/when healthcare professionals may support behaviour change to optimise lifelong brain health for plwMS. CONCLUSION Healthcare professionals recognise their critical role in encouraging and supporting the adoption of a brain-healthy lifestyle to optimise lifelong brain health for plwMS. However, discord is evident when they underestimate the complexity of translating knowledge of lifestyle-related behaviour change(s) into action. Greater awareness must be made in recognising and addressing the bidirectionality of external factors such as those in the SCT, that may influence how behaviour change occurs. PUBLIC CONTRIBUTION Healthcare professionals volunteered to be interviewed as part of the data collection phase of this study.

Abstract
A diet rich in proinflammatory components and inflammation are suggested to be significant risk factors for multiple sclerosis (MS). This study aimed to investigate the association between the risk of MS and the inflammatory potential of an individual's diet and dietary diversity through pro-inflammatory/anti-inflammatory food intake score (PAIFIS) and dietary diversity score (DDS). In a hospital-based case-control study, 397 participants, including 197 patients with MS and 200 healthy participants aged over 18 years, were evaluated. The history of smoking, dietary intake, and anthropometric characteristics, including body mass index, waist circumference, total body fat, and fat-free mass were assessed. A validated 160-item semiquantitative food frequency questionnaire was used to calculate the PAIFIS and DDS scores. The mean age of the participants was 32.45 ± 8.66 years, and most were females (274, 79.4%). The PAIFIS score was significantly higher among MS patients than healthy participants (p = 0.001). Between PAIFIS and DDS, only PAFIS was significantly related to MS risk (odds ratio, 1.002; 95% confidence interval, 1.001-1.004; p = 0.001). PAIFIS, as an index of dietary inflammation, can predict MS. Further studies are needed to document these findings.

Abstract
BACKGROUND AND PURPOSE Modifiable lifestyle factors, including diet, have been implicated in multiple sclerosis (MS) progression, but prospective evidence is limited. The aim of this study was to examine prospective relationships between quality of diet and subsequent disability over 7.5 years in an international cohort of people living with MS (pwMS). METHODS Data from 602 participants in the HOLISM (Health Outcomes and Lifestyle In a Sample of people with Multiple sclerosis) study were analysed. Quality of diet was assessed using the modified Diet Habits Questionnaire (DHQ). Disability was assessed using the Patient-determined MS Severity Score (P-MSSS). Characteristics of disability were assessed by log-binomial, log-multinomial and linear regression, adjusted for demographic and clinical covariates, as appropriate. RESULTS Higher baseline total DHQ scores (>80-89, >89%) were associated with lower risks of increased P-MSSS at 7.5 years (adjusted risk ratio [aRR] 0.46, 95% confidence interval [CI] 0.23, 0.91 and aRR 0.48, 95% CI 0.26, 0.89, respectively), and with less P-MSSS accrual (aβ = -0.38, 95% CI -0.78, 0.01 and aβ = -0.44, 95% CI -0.81, -0.06). Of the DHQ domains, fat subscore was most strongly associated with subsequent disability. Participants with reducing baseline-to-2.5- years total DHQ scores had greater risk of increased P-MSSS at 7.5 years (aRR 2.77, 95% CI 1.18, 6.53) and higher P-MSSS accrual (aβ = 0.30, 95% CI 0.01, 0.60). Participants reporting baseline meat and dairy consumption had greater risk of increased P-MSSS at 7.5 years (aRR 2.06, 95% CI 1.23, 3.45 and aRR 2.02, 95% CI 1.25, 3.25) and higher P-MSSS accrual (aβ = 0.28, 95% CI 0.02, 0.54 and aβ = 0.43, 95% CI 0.16, 0.69, respectively). However, reported meat consumption was confounded by quality of diet. Changes in meat or dairy consumption from baseline were inconsistently associated with subsequent disability. CONCLUSIONS We show for the first time robust long-term associations between quality of diet and subsequent disability progression in pwMS. Subject to replication, dietary modification may represent a point of intervention for reducing disability in pwMS.

Abstract
BACKGROUND People living with multiple sclerosis (plwMS) seek access to information on evidence-based lifestyle-related risk factors associated with multiple sclerosis (MS). As the internet has made delivery of lifestyle information increasingly accessible and cost-effective, we designed the Multiple Sclerosis Online Course (MSOC) to deliver a multimodal lifestyle modification program for plwMS. Two MS online courses were developed: the intervention course based on lifestyle recommendations of the Overcoming Multiple Sclerosis (OMS) program and the standard-care course representing standard lifestyle recommendations from other MS websites. We examined for feasibility in a pilot randomised controlled trial (RCT), where satisfactory completion and accessibility were achieved across both study arms. From this success, a protocol for a larger RCT was developed to examine the effectiveness of MSOC in improving health-related quality of life (HRQoL) and other health outcomes in plwMS. METHODS/DESIGN This single-blinded RCT will recruit n = 1,054 plwMS. Participants in the intervention arm will receive access to a MSOC with seven modules providing evidence-based information on the OMS program. Participants in the control group will receive access to a MSOC of identical format, with seven modules providing general MS-related information and lifestyle recommendations sourced from popular MS websites, e.g. MS societies. Participants will complete questionnaires at baseline and at 6, 12, and 30 months after course completion. The primary endpoint is HRQoL, as measured by MSQOL-54 (both physical and mental health domains) at 12 months following course completion. Secondary outcomes are changes to depression, anxiety, fatigue, disability, and self-efficacy as measured by Hospital Anxiety and Depression Scale, Patient-Determined Disease Steps and University of Washington Self-Efficacy Scale, respectively, assessed at each timepoint. Further assessments will include quantitative post-course evaluation, adoption and maintenance of behaviour change from follow-up survey data, and qualitative analysis of participants' outcomes and reasons for course completion or non-completion. DISCUSSION This RCT aims to determine whether an online intervention course delivering evidence-based lifestyle modification recommendations based on the Overcoming Multiple Sclerosis program to plwMS is more effective at improving HRQoL, and other health outcomes post-intervention, compared with an online standard-care course. TRIAL REGISTRATION This trial was registered prospectively with the Australian New Zealand Clinical Trials Registry, www.anzctr.org.au , identifier ACTRN12621001605886.

Higher diet quality is associated with short and long-term benefits on SF-6D health state utilities: a 5-year cohort study in an international sample of people with multiple sclerosis. Qual Life Res 2023:10.1007/s11136-023-03361-w. [PMID: 36821020 DOI: 10.1007/s11136-023-03361-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/30/2023] [Indexed: 02/24/2023]
Abstract
BACKGROUND/PURPOSE Health state utilities (HSU) are a subjective measure of an individual's health-related quality of life (HRQoL), adjusted by societal or patient relative preference weights for living in different states of health-related quality of life (HRQoL), derived from patient-reported responses to multi-attribute utility instrument (MAUI), and can be used as inputs for cost-utility analyses and in clinical assessment. This research assessed associations of diet with subsequent HSU in a large international cohort of people living with multiple sclerosis (MS), a progressive autoimmune condition of the central nervous system. METHODS HSUs were generated from responses to Short-Form Six-Dimension (SF-6D) MAUI, and quality-of-the-diet by Diet Habits Questionnaire (DHQ). Cross-sectional, and short- and long-term prospective associations of DHQ with HSU evaluated by linear regression at 2.5- and 5-years. Pooled prospective associations between DHQ and HSU evaluated using linear and quantile regression. Analyses adjusted for relevant demographic and clinical covariates. RESULTS Among 839 participants, baseline DHQ scores showed short- and long-term associations with subsequent HSU, each 10-unit increase in total DHQ score associated with 0.008-0.012 higher HSU (out of 1.00). These associations were dose-dependent, those in the top two quartiles of baseline DHQ scores having 0.01-0.03 higher HSU at follow-up, 0.03 being the threshold for a minimally clinically important difference. Fat, fiber, and fruit/vegetable DHQ subscores were most strongly and consistently associated with better HSU outcomes. However, baseline meat and dairy consumption were associated with 0.01-0.02 lower HSU at subsequent follow-up. CONCLUSIONS A higher quality-of-the-diet showed robust prospective relationships with higher HSUs 2.5- and 5-years later, substantiating previous cross-sectional relationships in this cohort. Subject to replication, these results suggest interventions to improve the quality-of-the-diet may be effective to improve HRQoL in people living with MS.

Impact of nutrition counseling on anthropometry and dietary intake of multiple sclerosis patients at Kasr Alainy Multiple Sclerosis Unit, Cairo, Egypt 2019-2020: randomized controlled clinical trial. Arch Public Health 2023; 81:11. [PMID: 36691061 PMCID: PMC9869589 DOI: 10.1186/s13690-022-01013-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2022] [Accepted: 12/12/2022] [Indexed: 01/24/2023] Open
Abstract
BACKGROUND Faulty dietary habits and overnutrition are prevalent among Egyptian patients with multiple sclerosis (MS) who do not receive nutrition care as part of treatment. Thus, this study was conducted to identify the effect of nutrition counseling on the nutritional status of patients with MS. This endeavor might provide evidence for the value of counseling in such a setting and advance the integration of nutrition counseling into the routine management of patients with MS. METHODS A single-blinded, parallel-randomized controlled clinical trial was conducted at Kasr Alainy MS Unit on 120 eligible patients with MS from September 2019 to February 2020. Patients were randomly allocated to either the nutrition counseling intervention group (IG) or the control group (CG). Allocation concealment was performed by using sequentially numbered opaque sealed envelopes. All patients were assessed initially and complied with the Kasr Alainy MS Unit standard management protocol for the study period. Only patients in the IG underwent initial nutrition counseling sessions followed by a monthly evaluation. All patients were assessed at the end of the 3-month follow-up period. Sociodemographic data were gathered through a structured interview. Nutritional status was assessed anthropometrically and via 24-h recall. The 2 groups were compared initially and at the end of the follow-up. Both intention-to-treat and per-protocol analyses were conducted. RESULTS At baseline assessment, the prevalence of overweight and obesity was 31.7% and 32.5%, respectively, and the mean body mass index was 27.7 ± 5.7 kg/m2. Mean waist circumference was 93.5 ± 11.9 and 99.2 ± 13.1 cm for males and females, respectively. Approximately 27.3% of males and 83.9% of females showed abdominal obesity. After 3 months of counseling, weight, body mass index, waist circumference, nutrient intake and adequacy significantly improved in the IG (p < 0.05). CONCLUSION Nutrition counseling significantly improved anthropometric measurements, dietary habits, nutrient intake and adequacy. TRIAL REGISTRATION The study was registered on ClinicalTrial.gov and was given a code (NCT04217564).

Alcohol inhibits the metabolism of dimethyl fumarate to the active metabolite responsible for decreasing relapse frequency in the treatment of multiple sclerosis. PLoS One 2022; 17:e0278111. [PMID: 36441753 PMCID: PMC9704628 DOI: 10.1371/journal.pone.0278111] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Accepted: 11/10/2022] [Indexed: 11/29/2022] Open
Abstract
Dimethyl fumarate (DMF) is a first-line prodrug for the treatment of relapsing-remitting multiple sclerosis (RRMS) that is completely metabolized to monomethyl fumarate (MMF), the active metabolite, before reaching the systemic circulation. Its metabolism has been proposed to be due to ubiquitous esterases in the intestines and other tissues, but the specific enzymes involved are unknown. We hypothesized based on its structure and extensive presystemic metabolism that DMF would be a carboxylesterase substrate subject to interaction with alcohol. We sought to determine the enzymes(s) responsible for the extensive presystemic metabolism of DMF to MMF and the effect of alcohol on its disposition by conducting metabolic incubation studies in human recombinant carboxylesterase-1 (CES1), carboxylesterase-2 (CES2) and human intestinal microsomes (HIM), and by performing a follow-up study in an in vivo mouse model. The in vitro incubation studies demonstrated that DMF was only metabolized to MMF by CES1. Consistent with the incubation studies, the mouse pharmacokinetic study demonstrated that alcohol decreased the maximum concentration and area-under-the-curve of MMF in the plasma and the brain after dosing with DMF. We conclude that alcohol may markedly decrease exposure to the active MMF metabolite in the plasma and brain potentially decreasing the effectiveness of DMF in the treatment of RRMS.

Abstract
Since the first model of experimental autoimmune encephalomyelitis (EAE) was introduced almost a century ago, there has been an ongoing scientific debate about the risks and benefits of using EAE as a model of multiple sclerosis (MS). While there are notable limitations of translating EAE studies directly to human patients, EAE continues to be the most widely used model of MS, and EAE studies have contributed to multiple key breakthroughs in our understanding of MS pathogenesis and discovery of MS therapeutics. In addition, insights from EAE have led to a better understanding of modifiable environmental factors that can influence MS initiation and progression. In this review, we discuss how MS patient and EAE studies compare in our learning about the role of gut microbiome, diet, alcohol, probiotics, antibiotics, and fecal microbiome transplant in neuroinflammation. Ultimately, the combination of rigorous EAE animal studies, novel bioinformatic approaches, use of human cell lines, and implementation of well-powered, age- and sex-matched randomized controlled MS patient trials will be essential for improving MS patient outcomes and developing novel MS therapeutics to prevent and revert MS disease progression.

Abstract
Multiple sclerosis (MS) is a neuroinflammatory and neurodegenerative disease of unknown etiology. However, several studies suggest that infectious agents, e.g., Human Herpes Viruses (HHV), may be involved in triggering the disease. Molecular mimicry, bystander effect, and epitope spreading are three mechanisms that can initiate immunoreactivity leading to CNS autoimmunity in MS. Theiler’s murine encephalomyelitis virus (TMEV)-induced demyelinating disease (TMEV-IDD) is a pre-clinical model of MS in which intracerebral inoculation of TMEV results in a CNS autoimmune disease that causes demyelination, neuroaxonal damage, and progressive clinical disability. Given the spectra of different murine models used to study MS, this review highlights why TMEV-IDD represents a valuable tool for testing the viral hypotheses of MS. We initially describe how the main mechanisms of CNS autoimmunity have been identified across both MS and TMEV-IDD etiology. Next, we discuss how adaptive, innate, and CNS resident immune cells contribute to TMEV-IDD immunopathology and how this relates to MS. Lastly, we highlight the sexual dimorphism observed in TMEV-IDD and MS and how this may be tied to sexually dimorphic responses to viral infections. In summary, TMEV-IDD is an underutilized murine model that recapitulates many unique aspects of MS; as we learn more about the nature of viral infections in MS, TMEV-IDD will be critical in testing the future therapeutics that aim to intervene with disease onset and progression.

Abstract
OBJECTIVES. Motivation for the study: multiple sclerosis (MS) is a complex disease that requires management by different disciplines. Data on Latin American patients is scarce, therefore, the usually used theoretical references are from other population groups. Main findings: sociodemographic (male), clinical (concomitant neurological diseases) and radiological (active lesions in magnetic resonance imaging) factors were found to be associated with disease progression. Implications: taking the above into account when approaching patients in daily clinical practice, it is possible to identify when their condition has greater possibilities of progression and thus eventually prevent complications. To determine the sociodemographic, clinical and radiological factors associated with time to disability progression in patients with multiple sclerosis (MS). MATERIALS AND METHODS. Cross-sectional descriptive study with an analytical component, based on clinical records of patients at the Neurological Institute of Colombia, between 2013 and 2021. Progression to disability in MS patients was defined as the time to an increase of at least 0.5 points in the EDSS (Expanded Disability Status Scale) score, sustained for at least six months. A Cox regression model was used to estimate the survival function and Hazard Ratios (HR) with their 95% confidence intervals (95% CI). RESULTS. We included 216 patients, of whom 25% progressed to disability, median survival was 78 months (95% CI: 70-83), active lesions (HR = 1.94; 95% CI: 1.10-3.44), cerebellar complications (HR = 2.03; 95% CI: 0. 99-4.16), being male (HR = 2.5; 95% CI: 1.32-4.73), and having neurological diseases (HR = 2.18; 95% CI: 1.03-4.61) were associated as risk factors. While relapsing remitting MS (HR = 0.63; 95% CI: 0.31-1.26) and age at diagnosis less than 40 years (HR = 0.96; 95% CI: 0.53-1.76) were associated as protective factors. CONCLUSIONS. Progression is affected by many factors, and there is no single independent factor.

Abstract
BACKGROUND There have been inconsistent results regarding the association between alcohol intake and susceptibility to multiple sclerosis. OBJECTIVE To assess the potential role of alcohol intake regarding the risk of multiple sclerosis by using a meta-analytic approach. DESIGN AND SETTING Observational meta-analysis study conducted in a hospital in China. METHODS The electronic databases of PubMed, EMBASE and the Cochrane library were systematically searched for eligible studies from their inception up to January 2020. The summary odds ratio (OR) with 95% confidence interval (CI) was applied to assess the association between alcohol intake and multiple sclerosis, using a random-effects model. RESULTS One prospective cohort study and eight case-control studies involving a total of 211,396 subjects and 10,407 cases of multiple sclerosis were selected for the final meta-analysis. From the pooled data, no significant association between alcohol intake and multiple sclerosis risk was found (OR: 0.94; 95% CI: 0.73-1.22; P = 0.668), and this conclusion was judged to be robust. Subgroup analysis found that intake of beer was associated with an increased risk of multiple sclerosis (OR: 1.58; 95% CI: 1.12-2.23; P = 0.010). CONCLUSION This study found that beer intake could cause an excess risk of multiple sclerosis. Further large-scale prospective studies should be conducted to verify this conclusion.

Abstract
BACKGROUND Diet has been associated with the onset and progression of multiple sclerosis (MS). Multiple diets, varying in recommendations, have been proposed as beneficial to people with MS. The characteristics of those who follow specific diet-programs and the relationships of these diet-programs with diet quality is under-explored. METHODS Data from the HOLISM study were analysed. Adherence to selected MS-specific diets (Ashton Embry Best Bet, McDougall, Overcoming MS (OMS), Palaeolithic, Swank, and Wahls Elimination) were each queried on 5-point Likert scales, and moderate (≥3/5) and rigorous (≥4/5) adherence defined. Sociodemographic and clinical characteristics of adherence were evaluated by log-binomial regression. Relationships of diet-program adherence with diet quality as measured by Diet Habits Questionnaire were assessed by linear and log-binomial regression, as appropriate, adjusted for age, sex, socioeconomic status (SES), education, and clinically significant fatigue. RESULTS Forty-nine percent of participants reported at least 12-month adherence to a diet-program for their MS. Of these, 31.3% rigorously adhered to OMS, 4.9% to Swank, 1.7% to Wahls, and <1.5% to other diet-programs. Only adherence to any diet-program, OMS, Wahls, and Swank, were quantitatively assessed. Females, and participants of lower-than-average SES and longer disease duration were less adherent to any diet-program for MS, as well as those with higher disability, more clinically significant fatigue, greater depression risk, and more comorbidities. Those with higher-than-average SES were more adherent, as were those with higher physical and mental quality of life. Similar relationships were seen for OMS diet-program adherence. Adherence to Wahls diet-program was higher among those with progressive MS types and longer disease duration. No associations were found for adherence to Swank diet-program. Overall diet quality was higher among participants following any diet-program, particularly OMS and Swank, but not Wahls. CONCLUSION Greater adherence to MS specific diets was associated with higher SES, and higher quality of life. Following any diet program was associated with higher overall diet quality, with those adhering to the OMS diet having the highest diet quality. These results may inform health professionals in providing guidance to patients regarding diet in MS.

Abstract
BACKGROUND Growing evidence suggests a role of lifestyle modification in improved health outcomes for people with multiple sclerosis (pwMS); however, perspectives of pwMS who engage in lifestyle modification are lacking. OBJECTIVE We explored perspectives of pwMS regarding the modification of lifestyle-related risk factors in multiple sclerosis (MS) for disease management to understand attitudes to and experiences of lifestyle modification as part of self-management from a patient perspective. DESIGN Participants were ≥18 years and English speaking who responded to a free-text open-ended question in the Health Outcomes and Lifestyle In a Sample of pwMS (HOLISM), an international online survey. Responses were analysed utilizing inductive thematic analysis. RESULTS Under the exploration of lifestyle modification, themes describing the experiences and attitudes of participants included practical challenges and physical and psychological barriers, enablers of change and experienced outcomes. Although participants reported some practical and psychological challenges to adoption and maintenance of lifestyle behaviours, many expressed an ability to gain control of MS through engagement with lifestyle behaviours and the development of hope and optimism that accompanied this sense of control, at times leading to a sense of personal transformation. CONCLUSION Findings highlight the challenges experienced by pwMS in adopting lifestyle modifications for disease management as well as the positive benefits from following healthy lifestyle behaviours. Our findings may form the basis of more focussed qualitative explorations of the experiences and outcomes of lifestyle modification in MS in the future. PATIENT CONTRIBUTION Consenting pwMS completed a survey capturing data on demographics, clinical course, lifestyle behaviours and health outcomes.

Abstract
Background and purpose Modifiable lifestyle factors, including diet, may affect clinical outcomes in multiple sclerosis (MS). This study assessed the relationships between diet, and disability, fatigue, and depression risk in people with MS. Methods Participants from the Health Outcomes and Lifestyle In a Sample of people with Multiple sclerosis (HOLISM) international cohort were assessed over 2.5 years. Dietary data were obtained using a modified Diet Habits Questionnaire (DHQ), disability using the calculated Patient‐determined MS Severity Score (P‐MSSS), fatigue using the Fatigue Severity Scale, and depression risk using the Patient Health Questionnaire‐2. Participants reported whether they were experiencing symptoms due to a recent relapse. Cross‐sectional and prospective relationships of diet and disease outcomes were explored, adjusted for relevant confounders. Results Among 1,346 participants, higher DHQ scores showed significant dose‐dependent associations with lower frequencies of severe disability, fatigue, and depression risk, cross‐sectionally. Prospectively, higher baseline DHQ scores were associated with a lower risk of increasing disability, those above the median having 41% and 36% lower risk of increasing disability, and 0.30 P‐MSSS points less disability progression, but were not associated with fatigue or depression risk. Meat consumption was associated with 0.22 P‐MSSS points higher disability cross‐sectionally, while prospectively, baseline meat consumption was associated with 76% higher risk of increasing disability and 0.18 P‐MSSS points higher disability progression. Dairy consumption showed mixed associations cross‐sectionally and prospectively. Conclusions These results show that better quality of diet, as well as not consuming meat, were associated with reduced disability progression in people with MS. Substantiation of these findings in other settings may inform opportunities to manage disability progression in people with MS using dietary modifications.

Abstract
People with multiple sclerosis (PwMS) often experience uncertainty and fear about their futures. Partners of PwMS may share their concerns and experience fears about their own futures, limitations on their lives, ability to work, and becoming a carer. For PwMS, modification of lifestyle-related risk factors has been associated with improved health outcomes. For PwMS who attended residential lifestyle modification workshops (RLMW), sustained improved health outcomes have been demonstrated. Whether improved outcomes for PwMS who engage with lifestyle modification translate to improved partner perceptions of the future, is yet to be explored. We explored the perspectives of partners of PwMS who had attended a RLMW and the impact that the person with MS’s illness and their engagement with lifestyle modification had on their partners’ views of the future. Analysis of 21 semi-structured interviews used a methodology informed by Heidegger’s Interpretive Phenomenology. Three themes emerged: ‘uncertainty’, ‘planning for the future’ and ‘control, empowerment and confidence’. Subthemes included MS and lifestyle modification being a catalyst for positive change; developing a sense of control and empowerment; and hope, optimism and positivity. Lifestyle modification may provide benefits, not only to PwMS, but also to their partners, and should be considered part of mainstream management of MS.

Abstract
Inflammation is a physiological response to injury, stimulating tissue repair and regeneration. However, the presence of peculiar individual conditions can negatively perturb the resolution phase eventually leading to a state of low-grade systemic chronic inflammation, characterized by tissue and organ damages and increased susceptibility to non-communicable disease. Marine n-3 polyunsaturated fatty acids (n-3 PUFAs), mainly eicosapentaenoic (EPA) and docosahexaenoic acid (DHA), are able to influence many aspects of this process. Experiments performed in various animal models of obesity, Alzheimer's disease and multiple sclerosis have demonstrated that n-3 PUFAs can modulate the basic mechanisms as well as the disease progression. This review describes the available data from experimental studies to the clinical trials.

Abstract
Multiple sclerosis (MS) is the most common chronic inflammatory and neurodegenerative disease of the central nervous system (CNS). An interesting feature that this debilitating disease shares with many other inflammatory disorders is that susceptibility is higher in females than in males, with the risk of MS being three times higher in women compared to men. Nonetheless, while men have a decreased risk of developing MS, many studies suggest that males have a worse clinical outcome. MS exhibits an apparent sexual dimorphism in both the immune response and the pathophysiology of the CNS damage, ultimately affecting disease susceptibility and progression differently. Overall, women are predisposed to higher rates of inflammatory relapses than men, but men are more likely to manifest signs of disease progression and worse CNS damage. The observed sexual dimorphism in MS may be due to sex hormones and sex chromosomes, acting in parallel or combination. In this review, we outline current knowledge on the sexual dimorphism in MS and discuss the interplay of sex chromosomes, sex hormones, and the immune system in driving MS disease susceptibility and progression.

[PMID: 31656633 PMCID: PMC6791040 DOI: 10.1177/2055217319881769] [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: 03/10/2019] [Revised: 08/29/2019] [Accepted: 09/21/2019] [Indexed: 11/15/2022] Open
Abstract
Background Risk factors for chronic disease include smoking, hazardous alcohol consumption, physical inactivity, unhealthy body mass index and poor diet (SNAP factors). In multiple sclerosis (MS) SNAP factors are associated with health outcomes such as disability in cross-sectional studies, but longitudinal data are lacking. Objective The objective of this study was to assess whether a combined SNAP risk score predicts disability worsening. Methods Longitudinal self-reported data from two time-points 2.5 years apart from an international survey of 1225 people with MS were used in linear regression models adjusted for potential confounding. Disability worsening was measured using the patient-derived Multiple Sclerosis Severity Score. Results The majority (62%) had two or more risk factors, with insufficient fruit and vegetable intake (83%), unhealthy body mass index (42%) and physical inactivity (33%) most common. Some SNAP factors at follow-up were associated with disability at follow-up (cross-sectionally), and in addition there was some evidence that increasing risk factors was associated with disability worsening over the 2.5 year study period. Baseline SNAP score was not predictive of disability worsening at follow-up, however. Conclusion Known risk factors for morbidity and mortality were common and associated with disability cross-sectionally, but not prospectively. Further studies using longer time frames, objective measures and interventions may elucidate potential benefits from changes in risk factors on MS outcomes.

Abstract
INTRODUCTION Multiple sclerosis (MS), the most common neurological disease causing disability in young adults, is widely recognised as a major stress factor. Studies have shown that the first years after the diagnosis are distressing in terms of adjustment to the disease and that MS negatively affects patients' psychological well-being, quality of life (QoL) and social functioning. However, the links between disease-specific variables at diagnosis, resilience and psychological adjustment of patients with MS remain largely unexplored, especially in adolescents and young adults. This observational study aims to fill the gap of knowledge on biopsychosocial characteristics and resilience of young adults with MS to evaluate the relationship among these variables and to develop a biopsychosocial model of resilience. METHODS AND ANALYSIS Biological and clinical characteristics of young adults newly diagnosed with MS will be investigated by collecting clinical information, performing neurological examinations, MRI and analysing cerebrospinal fluid and blood biomarkers (eg, measures of inflammation), body composition, gut microbiota and movement/perceptual markers. Psychosocial characteristics (eg, psychological distress, coping strategies), QoL, psychological well-being and resilience will be assessed by self-report questionnaires. Comparative statistics (ie, analysis of variance or unpaired samples t-test, correlation and regression analyses) will be applied to evaluate the relationship among biological, psychological and social factors. The results are expected to allow a comprehensive understanding of the determinants of resilience in young patients with MS and to inform resilience interventions, tailored to young patients' specific needs, aiming to reduce the risk of maladaptive reactions to the disease and to improve psychological well-being and QoL. ETHICS AND DISSEMINATION The study has been approved by the Verona University Hospital Ethics Committee (approval number: 2029CESC). The findings will be disseminated through scientific publications in peer-reviewed journals, conference presentations, social media and specific websites. TRIAL REGISTRATION NUMBER ClinicalTrials.gov (NCT03825055).

Abstract
Background Multiple sclerosis (MS), a demyelinating condition of the central nervous system with an unpredictable course, has a major impact on the lives of people with MS. Partners of people with MS may be significantly affected by the diagnosis, management and uncertainty around disease progression and may provide substantial support and care. Modification of lifestyle risk factors in conjunction with standard medical management has been associated with improved physical and mental quality of life. Adopting major lifestyle modification may have a multi-faceted impact on the person with MS and their partner. Experiences of partners of people with MS have been previously explored, but the experiences of partners of people with MS who adopt this strategy have not. As part of a larger study that aimed to explore partners’ lived experiences of and attitudes towards MS and lifestyle modification, this study reports the active steps and significant changes partners undertook to assist the person with MS and, at times, to also modify their own lives. Design Within an interpretive framework, using Heidegger’s phenomenological philosophy, a qualitative study of semi-structured interviews was conducted. Participants Aged greater than 18 years and in a spousal relationship with a person with MS who had undertaken an intensive residential lifestyle educational intervention promoting healthy lifestyle. Results Themes identified were: adjusting to lifestyle modification, understanding motivations and practical aspects of adjustment; seeking knowledge and support, exploring the ways partners sought positive support for themselves and the person with MS and abandoned negative influences; and embracing well-being, commitment and change, describing the major changes that partners made to their lives professionally and personally. Conclusions The experiences of these partners provide clinicians with insight into potential motivations and outcomes of lifestyle modification and suggest potentially positive aspects for those directly and indirectly affected by MS.

Health Outcomes and Lifestyle in a Sample of People With Multiple Sclerosis (HOLISM): Longitudinal and Validation Cohorts. Front Neurol 2018; 9:1074. [PMID: 30619037 PMCID: PMC6299875 DOI: 10.3389/fneur.2018.01074] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2018] [Accepted: 11/26/2018] [Indexed: 11/13/2022] Open
Abstract
Objective: To report the methodology and summary data of the Health Outcomes and Lifestyle In a Sample of people with Multiple sclerosis (HOLISM) longitudinal and validation cohorts. We report (1) data on participation, socio-demographics, disease characteristics, medication use, modifiable lifestyle risk factor exposures, and health outcomes of the HOLISM longitudinal cohort 2.5-years post enrolment; (2) attrition at this 2.5-year wave; and (3) baseline characteristics of the associated HOLISM validation cohort. Methods: The HOLISM longitudinal study recruited people internationally with self-reported diagnosed multiple sclerosis (MS) through web 2.0 platforms and MS society newsletters. Participants, first recruited in 2012, were invited 2.5-years later to participate in a follow-up survey. At both time points, participants completed a comprehensive online questionnaire of socio-demographics, modifiable lifestyle exposures, and health outcomes using validated and researcher-designed tools. The same methodology was used to recruit a new sample: the HOLISM validation cohort. Characteristics were explored using summary measures. Results: Of 2,466 people with MS at baseline, 1,401 (56.8%) provided data at 2.5-year follow-up. Attrition was high, likely due to limited amount of contact information collected at baseline. Completion of the 2.5-year wave was associated with healthier lifestyle, and better health outcomes. Participants completing follow-up had diverse geographical location, were predominantly female, married, unemployed or retired. At 2.5-year follow-up, nearly 40% were overweight or obese, most were physically active, non-smokers, consumed little alcohol, used vitamin D/omega-3 supplements, and 42% reported current disease-modifying drug use. Thirty percentage of reported cane or gait disability, while 13% relied on major mobility supports (Patient Determined Disease Steps). Approximately half the respondents reported a comorbidity, 63% screened positive for clinically significant fatigue (Fatigue Severity Scale), and 22% screened positive for depression (Patient Health Questionnaire-9). The validation cohort's characteristics were mostly consistent with previously reported HOLISM baseline data. Conclusions: Exploring prospective associations of modifiable environmental/behavioral risk factors with health outcomes in this international longitudinal sample of people with MS will be beneficial to MS research. Impacts of attrition and selection bias will require consideration. The validation cohort provides opportunity for replication of previous findings, and also for temporal validation of predictive models derived from the HOLISM cohort.

Longitudinal Associations of Modifiable Lifestyle Factors With Positive Depression-Screen Over 2.5-Years in an International Cohort of People Living With Multiple Sclerosis.

Abstract
Background: Depression is common and has a significant impact on quality of life for many people with multiple sclerosis (MS). A preventive management approach via modification of lifestyle risk factors holds potential benefits. We examined the relationship between modifiable lifestyle factors and depression risk and the change in depression over 2.5 years. Methods: Sample recruited using online platforms. 2,224 (88.9%) at baseline and 1,309 (93.4%) at 2.5 years follow up completed the necessary survey data. Depression risk was measured by the Patient Health Questionnaire-2 (PHQ-2) at baseline and Patient Health Questionniare-9 (PHQ-9) at 2.5-years follow-up. Multivariable regression models assessed the relationships between lifestyle factors and depression risk, adjusted for sex, age, fatigue, disability, antidepressant medication use, and baseline depression score, as appropriate. Results: The prevalence of depression risk at 2.5-years follow-up in this cohort was 14.5% using the PHQ-2 and 21.7% using the PHQ-9. Moderate alcohol intake, being a non-smoker, diet quality, no meat or dairy intake, vitamin D supplementation, omega 3 supplement use, regular exercise, and meditation at baseline were associated with lower frequencies of positive depression-screen 2.5 years later. Moderate alcohol intake was associated with greater likelihood of becoming depression-free and a lower likelihood of becoming depressed at 2.5-years follow-up. Meditating at least once a week was associated with a decreased frequency of losing depression risk, against our expectation. After adjusting for potential confounders, smoking, diet, physical activity, and vitamin D and omega-3 supplementation were not associated with a change in risk for depression. Conclusion: In a large prospective cohort study of people with MS and depression, in line with the emerging treatment paradigm of early intervention, these results suggest a role for some lifestyle factors in depression risk. Further studies should endeavor to explore the impact of positive lifestyle change and improving depression in people living with MS.

Abstract
Multiple sclerosis (MS) is an inflammatory and neurodegenerative disease of the central nervous system (CNS) probably caused, in most cases, by the interaction of genetic and environmental factors. This review first summarizes some clinical, epidemiological and pathological characteristics of MS. Then, the involvement of biochemical pathways is discussed in the development and repair of the CNS lesions and the immune dysfunction in the disease. Finally, the potential roles of peroxisome proliferator-activated receptors (PPAR) in MS are discussed. It is suggested that metabolic mechanisms modulated by PPAR provide a window to integrate the systemic and neurological events underlying the pathogenesis of the disease. In conclusion, the reviewed data highlight molecular avenues of understanding MS that may open new targets for improved therapies and preventive strategies for the disease.

Abstract
PURPOSE OF REVIEW This review aims to critically evaluate published studies examining diets and nutritional supplements (excepting vitamin D) for the impact on prevention and prognosis of multiple sclerosis (MS). RECENT FINDINGS There is a negative relationship between the Mediterranean diet and vascular disease, and vascular co-morbidities are associated with a worse MS prognosis. Low-fat, fish-based diets, sodium-restricted diets, calorie restriction, the paleo diet, and gluten-free diets have been examined, mostly in observational studies; results are inconclusive. With regard to nutritional supplements, pilot data show a possible benefit of biotin with respect to disability worsening in people with progressive MS (PMS). The best designed randomized controlled trials (RCTs) for PUFA supplementation have not shown significant impact, but several weaker RCTs have. Many other nutritional supplements have been tested, including several anti-oxidants. While some early studies show positive results, no result has been definitive. Unfortunately, there is no strong evidence for a direct benefit of any given dietary intervention on MS risk or prognosis. However, due to its relationship with vascular co-morbidities, the Mediterranean diet has the strongest rationale for employment in PwMS. Higher-quality clinical trials are needed to ascertain the possible benefits of nutritional supplements.

Abstract
Introduction: Being in an intimate relationship with a person with multiple sclerosis (MS) may have a substantial impact on the partner's quality of life. Existing research has largely focused on negative impacts of MS for both people with MS (PwMS) and their partners and has sampled the population of partners of PwMS who have primarily adopted standard medical management only. Modifiable lifestyle factors have become increasingly recognized in the management of MS symptoms and disease progression. For partners of PwMS who have undertaken lifestyle modification as an additional strategy to minimize disease progression, the impacts, both positive and negative remain unexplored. This research is unique as it focuses on partners of PwMS who have attempted to adopt major lifestyle interventions outside of the prevailing paradigm of MS management. Aim: To explore and interpret the lived experiences of partners of PwMS who have adopted lifestyle modification, to understand partners' attitudes to and experiences of the effect of MS and lifestyle modification on their life, relationship and view of the future. Method: Design: a qualitative, interpretive, phenomenological study using semi-structured interviews. Participants: English-speaking; aged 18 years or more; in a spousal relationship for 12 months or more with a person with MS who had attended a residential lifestyle educational intervention and undertaken lifestyle modification. Analysis: Interviews were recorded, transcribed verbatim and thematically analyzed using NVivo™ software. Results: Twenty-one partners were interviewed. This paper reports one of the study's themes, the psychological shift experienced by partners of PwMS. Sub-themes included adaptation; loss and grief; difficult emotions; reframing, re-evaluating and re-prioritizing; hope and optimism; empowerment and taking control; and self-awareness, greater understanding and personal growth. Conclusion: Partners of PwMS who have undertaken lifestyle modification experienced a broad range of psychological adjustments. Whilst reflecting the potential difficulties that partners of PwMS may experience, this group experienced a range of positive psychological changes that add to the literature regarding partners' potential experiences and may provide hope for those in partnerships with people with MS. This study provides themes to potentially inform a quantitative study of a larger population of partners of PwMS.

[PMID: 29074384 DOI: 10.1016/j.dhjo.2017.10.003] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2017] [Revised: 09/08/2017] [Accepted: 10/04/2017] [Indexed: 02/01/2023]
Abstract
BACKGROUND Persons with multiple sclerosis (MS) have many health conditions related to overweight and obesity, but little is known about how body composition among those with MS compares to those without MS at the same weight. OBJECTIVE To compare differences in whole body and regional body composition between persons with and without MS matched for sex and body mass index (BMI). METHODS Persons with MS (n = 51) and non-MS controls (n = 51) matched for sex and BMI. Total mass, lean mass, fat mass, and percent body fat (%BF) of total body and arm, leg, and trunk segments were assessed using dual-energy X-ray absorptiometry (DXA). RESULTS Men with MS had significantly less whole body lean mass (mean difference: 9933.5 ± 3123.1 g, p < 0.01) and higher fat mass (mean difference: 6079.0 ± 2137.4 g, p = .01) and %BF (mean difference: 9.43 ± 2.04%, p < 0.01) than BMI-matched non-MS counterparts. Further, men with MS had significantly lower lean mass in the arm (p = 0.02) and leg (p < 0.01) and higher fat mass in the arm (p = 0.01), leg (p = 0.03) and trunk (p = 0.03) than men without MS. Men with MS had significantly higher %BF in all three regions (p < 0.01) than men without MS. There were no differences between women with and without MS. CONCLUSIONS We observed significant differences in whole body and regional body composition between BMI-matched men with and without MS. Additional research is needed to further explore differences in body composition, adipose distribution, and the impact of these differences on the health and function of men with MS.

Abstract
Multiple sclerosis (MS) is a major cause of disability and poor quality of life (QOL). Previous studies have shown differences in MS health outcomes between countries. This study aimed to examine the associations between international regions and health outcomes in people with MS. Self-reported data were taken from the Health Outcomes and Lifestyle In a Sample of people with Multiple Sclerosis online survey collected in 2012. The 2,401 participants from 37 countries were categorized into three regions: Australasia, Europe, and North America. Differences were observed between regions in disability, physical and mental health QOL, fatigue, and depression, but most of these disappeared after adjusting for sociodemographic, disease, and lifestyle factors in multivariable regression models. However, adjusted odds for disability were higher in Europe [odds ratio (OR): 2.17, 95% confidence interval (CI): 1.28 to 3.67] and North America (OR: 1.79, 95% CI: 1.28 to 2.51) compared to Australasia. There may be other unmeasured factors that vary between regions, including differences in access and quality of healthcare services, determining disability in MS. When assessing differences in MS health outcomes, lifestyle factors and medication use should be taken into consideration.

Abstract
The autoimmune disease multiple sclerosis (MS) is characterized by relapses in the majority of patients. A definitive clinical diagnosis of relapse in MS can be complicated by the presence of an infection or comorbid disorder. In this mini-review, we describe efforts to develop enhanced imaging techniques and biomarker detection as future tools for relapse validation. There is emerging evidence of roles for meningeal inflammation, sex hormones, comorbid metabolic or mood disorders, and a dysregulated immune profile in the manifestation and severity of relapse. Specific subsets of immune cells likely drive the pathophysiology of relapse, and identification of a patient's unique immunological signature of relapse may help guide future diagnosis and treatment. Finally, these studies highlight the diversity in terms of relapse presentation, immunological signature, and response in patients with MS, indicating that going forward the best approach to assessment and treatment of relapse will be multifactorial and highly personalized.
