Abstract
BACKGROUND Multiple sclerosis (MS) is chronic progressive disease that poses a significant economic burden to patients and health care systems in the United States. We conducted a systematic literature review to provide up-to-date insights on the economic burden of MS in the United States. OBJECTIVE To comprehensively review and summarize the latest published evidence on the economic burden of MS with a focus on cost, resource use, and work productivity. METHODS A systematic literature search was conducted using the Embase and Medline databases to identify studies, published between January 2011 and July 2022, reporting cost, resource use, or work productivity outcomes among people with MS in the United States. Clinical trials, economic modeling studies, and review articles were excluded. Details of eligible studies, including study design, patient population, and study outcomes for the overall population, as well as subgroups of interest, were extracted and summarized qualitatively. RESULTS Overall, 65 studies reporting cost, resource use, or work productivity data were included with majority of studies using claims data. The direct costs associated with MS ranged from $16,614 (2006) to $72,744 (2017) per patient per year with diseasemodifying therapies (DMTs) being the major cost contributors accounting for 43%-78%. The indirect costs reported ranged from $9,122 (2017) to $30,601 (2011) per patient per year with absenteeism, early retirement, and informal care being the key drivers for indirect costs. Costs, resource use, and work impairment were significantly higher for patients with severe disability compared with those with mild disability. Pharmacy costs were the major cost drivers in patients with mild, moderate, and severe disability. Similarly, patients with relapses incurred significantly higher costs, resource use, and work impairment compared with those without relapses. Additional hospitalization charges were the major driver of higher costs in patients who experienced relapses compared with those without relapses. CONCLUSIONS Direct costs, particularly DMTs, appear to be the major cost drivers for people with MS in the United States. Availability of lower-cost therapies may considerably decrease the economic burden on these patients and the health care systems. Future research focusing on indirect costs, intangible costs, and their contributors would contribute to further understanding of economic burden to avoid underestimation of the financial burden experienced by the patients.

Abstract
BACKGROUND AND AIMS Relapses are an important clinical feature of multiple sclerosis (MS) that result in temporary negative changes in quality of life (QoL), measured by health state utilities (HSUs) (disutilities). We aimed to quantify disutilities of relapse in relapsing remitting MS (RRMS), secondary progressive MS (SPMS), and relapse onset MS [ROMS (including both RRMS and SPMS)] and examine these values by disability severity using four multi-attribute utility instruments (MAUIs). METHODS We estimated (crude and adjusted and stratified by disability severity) disutilities (representing the mean difference in HSUs of 'relapse' and 'no relapse' groups as well as 'unsure' and 'no relapse' groups) in RRMS (n = 1056), SPMS (n = 239), and ROMS (n = 1295) cohorts from the Australian MS Longitudinal Study's 2020 QoL survey, using the EQ-5D-5L, AQoL-8D, EQ-5D-5L-Psychosocial, and SF-6D MAUIs. RESULTS Adjusted mean overall disutilities of relapse in RMSS/SPMS/ROMS were - 0.101/- 0.149/- 0.129 (EQ-5D-5L), - 0.092/- 0.167/- 0.113 (AQoL-8D), - 0.080/- 0.139/- 0.097 (EQ-5D-5L-Psychosocial), and - 0.116/- 0.161/- 0.130 (SF-6D), approximately 1.5 times higher in SPMS than in RRMS, in all MAUI. All estimates were statistically significant and/or clinically meaningful. Adjusted disutilities of RRMS and ROMS demonstrated a U-shaped relationship between relapse disutilities and disability severity. Relapse disutilities were higher in 'severe' disability than 'mild' and 'moderate' in the SPMS cohort. CONCLUSION MS-related relapses are associated with substantial utility decrements. As the type and severity of MS influence disutility of relapse, the use of disability severity and MS-type-specific disutility inputs is recommended in future health economic evaluations of MS. Our study supports relapse management and prevention as major mechanisms to improve QoL in people with MS.

Multiple sclerosis and mental health related quality of life: The role of defense mechanisms, defense styles and family environment. AIMS Neurosci 2023; 10:354-375. [PMID: 38188008 PMCID: PMC10767059 DOI: 10.3934/neuroscience.2023027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 11/13/2023] [Accepted: 11/21/2023] [Indexed: 01/09/2024] Open
Abstract
Background Multiple sclerosis is a demyelinating chronic neurologic disease that can lead to disability and thus to deterioration of quality of life. Psychological parameters such as ego defense mechanisms, defense styles and family environment are important factors in the adaptation process, and as such they can play important roles in QoL. This study aims to assess the psychological factors as well as the clinical and demographic characteristics related to mental health quality of life (MHQoL). Methods This was an observational, cross-sectional study conducted in a sample of 90 people with MS in the years 2018-2020. All participants completed the following questionnaires: MSQoL-54, DSQ-88, LSI, FES-R, SOC, BDI-II, STAI. Disability was assessed using EDSS. Results In multiple linear regression, significant roles were played by depression (R2: 41.1%, p: 0.001) and, to a lesser extent, the event of a relapse (R2: 3.5%, p: 0.005), expressiveness (R2: 3.6%, p < 0.05) and image distortion style (R2: 4.5%, p: 0.032). After performing a hierarchical-stepwise analysis (excluding depression), the important factors were maladaptive defense style (R2: 23.7%, p: 0.002), the event of relapse (R2: 8.1%, p < 0.001), expressiveness (R2: 5.5%, p: 0.004) and self-sacrificing defense style (R2: 2.4%, p: 0.071). Conclusion Psychological factors play important roles in MHQoL of people with multiple sclerosis. Thus, neurologists should integrate in their practice an assessment by mental health specialists. Moreover, targeted psychotherapeutic interventions could be planned i to improve QoL.

Abstract
(1) Objective: We explore the predictive power of a novel stream of patient data, combining wearable devices and patient reported outcomes (PROs), using an AI-first approach to classify the health status of Parkinson's disease (PD), multiple sclerosis (MS) and stroke patients (collectively named PMSS). (2) Background: Recent studies acknowledge the burden of neurological disorders on patients and on the healthcare systems managing them. To address this, effort is invested in the digital transformation of health provisioning for PMSS patients. (3) Methods: We introduce the data collection journey within the ALAMEDA project, which continuously collects PRO data for a year through mobile applications and supplements them with data from minimally intrusive wearable devices (accelerometer bracelet, IMU sensor belt, ground force measuring insoles, and sleep mattress) worn for 1-2 weeks at each milestone. We present the data collection schedule and its feasibility, the mapping of medical predictor variables to wearable device capabilities and mobile application functionality. (4) Results: A novel combination of wearable devices and smartphone applications required for the desired analysis of motor, sleep, emotional and quality-of-life outcomes is introduced. AI-first analysis methods are presented that aim to uncover the prediction capability of diverse longitudinal and cross-sectional setups (in terms of standard medical test targets). Mobile application development and usage schedule facilitates the retention of patient engagement and compliance with the study protocol.

Cost Per Relapse Avoided for Ozanimod Versus Other Selected Disease-Modifying Therapies for Relapsing-Remitting Multiple Sclerosis in the United States. Neurol Ther 2023; 12:849-861. [PMID: 37000386 DOI: 10.1007/s40120-023-00463-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Accepted: 03/10/2023] [Indexed: 04/01/2023] Open
Abstract
INTRODUCTION This study assessed the cost-effectiveness of ozanimod compared with commonly used disease-modifying therapies (DMTs) for relapsing-remitting multiple sclerosis (RRMS). METHODS Annualized relapse rate (ARR) and safety data were obtained from a network meta-analysis (NMA) of clinical trials of RRMS treatments including ozanimod, fingolimod, dimethyl fumarate, teriflunomide, interferon beta-1a, interferon beta-1b, and glatiramer acetate. ARR-related number needed to treat (NNT) relative to placebo and annual total MS-related healthcare costs was used to estimate the incremental annual cost per relapse avoided with ozanimod vs each DMT. ARR and adverse event (AE) data were combined with drug costs and healthcare costs to manage relapses and AEs in order to estimate annual cost savings with ozanimod vs other DMTs, assuming a 1 million USD fixed treatment budget. RESULTS Treatment with ozanimod was associated with lower incremental annual healthcare costs to avoid a relapse, ranging from $843,684 vs interferon beta-1a (30 μg; 95% confidence interval [CI] - $1,431,619, - $255,749) to $72,847 (95% CI - $153,444, $7750) vs fingolimod. Compared with all other DMTs, ozanimod was associated with overall healthcare cost savings ranging from $8257 vs interferon beta-1a (30 μg) to $2178 vs fingolimod. Compared with oral DMTs, ozanimod was associated with annual cost savings of $6199 with teriflunomide 7 mg, $4737 with teriflunomide 14 mg, $2178 with fingolimod, and $2793 with dimethyl fumarate. CONCLUSION Treatment with ozanimod was associated with substantial reductions in annual drug costs and total MS-related healthcare costs to avoid relapses compared with other DMTs. In the fixed-budget analysis, ozanimod demonstrated a favorable cost-effective profile relative to other DMTs.

Abstract
BACKGROUND Patient-reported outcomes are increasingly used in the management of patients with multiple sclerosis to understand the patient's perspective of disease and treatment. These measures provide insights into important factors including treatment satisfaction, physical and psychological function, and quality of life. OBJECTIVE To present results from the real-world PRO-ACT study in patients with multiple sclerosis who switched to alemtuzumab from another disease-modifying therapy. METHODS This 24-month, prospective, multicenter, observational study had a primary endpoint of change in overall satisfaction, measured using the Treatment Satisfaction Questionnaire for Medication (TSQM) version 1.4. Secondary endpoints included the Multiple Sclerosis Impact Scale-29 (MSIS-29), Modified Fatigue Impact Scale-5 (MFIS-5), and the Patient-Determined Disease Steps (PDDS). Safety was monitored with adverse events (AEs). RESULTS Of 199 enrolled patients, improvements were observed in mean TSQM scores for overall satisfaction (baseline, 50.3; year 2, + 13.2; p < 0.0001), effectiveness (49.3 and + 12.2; p < 0.0001), and side effects (77.6 and + 4.5; p = 0.04). Improvements were also observed in MSIS-29 physical (52.4 and -6.0; p < 0.0001), MSIS-29 psychological (53.4 and -7.0; p = 0.0003), and MFIS-5 (12.8 and -1.7; p < 0.0001). Most (95.0%) patients experienced ≥ 1 AE (88.4% mild, 67.8% moderate). CONCLUSIONS The primary endpoint was met; the safety of alemtuzumab was consistent with pivotal studies.

Abstract
BACKGROUND Cancer is one of the diseases with the highest incidence and mortality in the world, and one that requires greater care (formal and informal). At present, the traditional informal caregiver is disappearing. The objective is to analyse the sociodemographic and health factors associated with the possible catastrophic financial effect on households of replacing informal care by formal care for patients with blood cancer, during the different stages of treatment in Spain. METHODS A total of 139 patients with haematological neoplasm who underwent stem cell transplantation completed a longitudinal questionnaire during each of three treatment phases. Of this population, 88.49% received informal care. The households were classified into those where the replacement of informal care with formal care would impose a financial burden exceeding 40% of equivalent household income, versus those who would not suffer this consequence. Three logistic regression models (one for each treatment phase) were estimated and the corresponding marginal effects determined. RESULTS The factors associated with a higher probability of financial catastrophe were married marital status, low education level, fair to very poor self-perceived health status, the diagnosis of leukaemia in the pre-transplant and first-year post-transplant phases and of multiple myeloma disease in the final post-transplant phase. CONCLUSIONS These findings reveal the need to design social policies to meet the care needs of patients with blood cancer which at present are covered by informal care. Given the foreseeable elimination of this option, these families must be protected from the financial burden incurred from the use of privately-contracted assistance.

Abstract
Introduction: In light of the increasing number of economic burden studies and heterogeneity in methodology and reporting standards, there is a need for robust evidence synthesis on an umbrella review level.Areas covered: We performed the first review of reviews of cost-of-illness studies in multiple sclerosis. Focusing on disaggregated costs by disease characteristics (disability level, relapse, disease course), we also characterized the underlying methodological evidence base of individual (primary) studies.Expert Commentary: We identified 17 reviews encompassing 111 unique primary studies, and a high degree of overlap across reviews. Costs were substantial, rising with disability level, relapse episodes, and disease progression. Disability was the key cost driver. Compared to mild disability, total costs for moderate disability were 1.4-2.3-fold higher and 1.8-2.9-fold higher for severe disability. With escalating disability, the share of costs outside the health system (indirect costs, informal care) increasingly outweighed the share of direct medical costs. Of all 111 primary studies, 72% gathered resource use/loss data by patient self-report. Associated costs were mostly reported by disability level (75%), followed by relapse (48%) and disease course (21%). In conclusion, although heterogeneity can make in-depth comparisons of costs across studies impossible, important patterns are broadly apparent.

Abstract
Background Relapses are common among patients with multiple sclerosis (MS) despite treatment with disease-modifying therapies. Repository corticotropin injection (RCI, Acthar® Gel), plasmapheresis (PMP), and intravenous immunoglobulin (IVIg) are alternative therapies for MS relapse. There is a dearth of economic assessments of these therapies for the acute exacerbations of MS. This study estimated the cost-effectiveness of RCI compared to PMP or IVIg. Methods A Markov state-transition model compared outcomes (costs, relapses, remission, and utilities) with RCI versus PMP or IVIg for the acute exacerbations in MS. The model was developed from the United States (US) payer and societal perspectives over one to three years. Patients initiated on alternative therapies were evaluated in one-day increments for the first 30 days during treatment. The model assumes the natural history of MS after treatment in the first month, adjusting for the effect of treatment. Incremental cost-effectiveness ratios (ICERs) were estimated as cost per quality-adjusted life-year (QALY) gained. The uncertainty in model parameters was evaluated in probabilistic sensitivity analyses. Results In the base case, RCI has an ICER of USD 42,078 per QALY compared to PMP over one year from the payer perspective and is dominant over two and three years; RCI is dominant compared to PMP from the societal perspective over all three years. Compared to IVIg, RCI is a dominant strategy from both payer and societal perspectives over all three years. Probabilistic sensitivity analysis supports the base case findings, suggesting that RCI may be cost-effective versus PMP and IVIg for acute exacerbations in MS. Conclusion RCI is a cost-effective alternative treatment for MS relapses compared to PMP and IVIg from the US payer and societal perspectives.

Abstract
BACKGROUND Studies have shown that oral high-dose methylprednisolone (MP) is non-inferior to intravenous MP in treating multiple sclerosis relapses in terms of effectiveness and tolerance. In order to assist with resource allocation and decision-making, its cost-effectiveness must also be assessed. Our objective was to evaluate the cost-utility of per os high-dose MP as well as the cost-savings associated with implementing the strategy. METHODS A cost-utility analysis at 28 days was carried out using data from the French COPOUSEP multicenter, double-blind randomized controlled non-inferiority trial and the statutory health insurance reimbursement database. Costs were calculated using a societal perspective, including both direct and indirect costs. An incremental cost-effectiveness ratio was calculated and bootstrapping methods assessed the uncertainty surrounding the results. An alternative scenario analysis in which MP was administered at home was also carried out. A budgetary impact analysis was carried at five years. RESULTS In the conditions of the trial (hospitalized patients), there was no significant difference in utilities and costs at 28 days. The incremental cost-effectiveness ratio was €15,360 per quality-adjusted life-year gained. If multiple sclerosis relapses were treated at home, oral MP would be more effective, less costly and associated with annual savings up to 25 million euros for the French healthcare system. CONCLUSIONS Oral MP is cost-effective in the treatment of multiple sclerosis relapses and associated with major savings.

Wicks CR, Sloan R, DiMauro S, Thompson EL, Billington S, Webb M, Pepper G. Patients' experiences of self-identification, seeking support, and anticipation of potential relapse in multiple sclerosis. Mult Scler Relat Disord 2021; 56:103259. [PMID: 34628265 DOI: 10.1016/j.msard.2021.103259] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2021] [Revised: 08/17/2021] [Accepted: 09/06/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUND Multiple sclerosis (MS) relapses are associated with increased disability, reduced quality of life and negative psychosocial impacts. However, they often go unrecognised; people with MS (MSers) may face barriers to self-identification of relapses or seeking support for them. The charity Shift.ms sought to better understand 1) MSers' challenges in self-identifying potential relapses, 2) where MSers' seek support for potential relapses, and 3) the impact of the anticipation of relapses on MSers' wellbeing and daily living. METHODS Shift.ms developed a patient perspective 8-question pilot survey (included likert-style, multiple-choice, and optional free-text responses) and shared it with Shift.ms' international online community (n = 20,052). Descriptive quantitative analysis, and content analysis and thematic analysis of qualitative free-text responses were used. RESULTS 1,737 MSers responded. Just under one third (29.9%) of MSers reported that it takes them 24 h or less to self-identify a potential relapse, while more than half (54.5%) reported that identification occurs within 48 h; 55% MSers felt that the "at least 24 h" clinical criterion of relapse classification was appropriate. Challenges to relapse self-identification included confounding background symptoms or infection, variability of relapse symptoms, and individualistic nature of MS. Fatigue was reported to be the most common symptom of relapse (75%), however fatigue was also the symptom most commonly mistaken for relapse (40%). Barriers to relapse self-identification were a shorter duration since MS diagnosis and a perceived lack of consensus around relapse classification. Respondents reported they most often seek relapse support/advice from healthcare professionals (HCPs) (37.1%), family/friends (32.1%), or not at all (16.9%). Rather than temporal criteria (i.e. the 24 h criterion), participants felt that severity of symptoms could play a more critical role in whether to seek support for a potential relapse. Barriers to seeking support/advice included variability in HCP advice and feelings of invalidation. Anticipation of relapses negatively impacted MSers wellbeing; led to reduced participation in activities, and the development of adjustment/coping strategies. Relapse triggers included stress, reduced self-care, infection/illness; 78.5% reported stress or anxiety had triggered relapse. CONCLUSIONS These findings highlight difficulties MSers face in self-identifying relapses, barriers to accessing support, and impact of anticipation of relapses. They also highlight opportunities for improved MSer and HCP communication, dialogue and two-way education to help optimise patient access to relapse support and intervention.

Abstract
BACKGROUND Relapses of multiple sclerosis are burdensome events and entail potentially lasting loss of function. People with multiple sclerosis have to consider corticosteroids, providing limited benefits and the risk of adverse effects. OBJECTIVE To develop and validate a questionnaire investigating the internal process of people with multiple sclerosis making decisions about corticosteroids. METHODS The questionnaire is structured by three domains, attitude, subjective social norm, and perceived behavioural control, which according to the theory of planned behaviour determine action planning. The development is inspired by a previous questionnaire studying decisions on immunotherapy. The questionnaire was tested in qualitative think-aloud interviews (n=10) for feasibility and comprehensibility and in an online survey (n=203) to assess construct and criterion validity. RESULTS The 18-item questionnaire was considered feasible and comprehensible. It predicted the intention to receive corticosteroids in up to 82.3% of cases. "Subjective social norm" impacted most on intention. The questionnaire also proved sensitive for autonomy preferences of people with multiple sclerosis. CONCLUSION This study shows that the questionnaire appropriately explains the internal process people with multiple sclerosis run through when considering corticosteroids. It can be used to inform developments of tailored support for people with multiple sclerosis in making informed decisions about relapse management.

Abstract
BACKGROUND Multiple Sclerosis (MS) can be categorised as relapse onset MS (ROMS) and progressive onset MS (PROMS). We aimed to examine if health-related quality of life (in terms of health state utilities [HSUs] and dimensional scores) differed by onset type, in which health dimensions the differences were most pronounced, and whether these differences remained when stratified by disability severity. METHODS We estimated HSUs and the unique composite 'super-dimension' and 'individual dimension' scores (crude, age, sex, disease duration and disease modifying therapies use adjusted; and stratified by onset type and disability severity) for a sample of 1577 participants in the Australian MS Longitudinal Study, using the Assessment of Quality of Life (AQoL)-8D. RESULTS Adjusted mean overall HSU of PROMS was 0.55, 0.07 lower than ROMS. Adjusted mean physical and psychosocial super-dimension scores for PROMS were 0.51 and 0.28, 0.07 and 0.06 lower than for ROMS, respectively. For the individual health dimensions, the largest difference was seen in independent living (-0.12), followed by relationships (-0.07), and self-worth (-0.07). Whilst HSUs and dimensional scores were negatively associated with increasing disability severity in both onset types, estimates by disability severity did not differ between the two cohorts. CONCLUSIONS Our study provides a comprehensive assessment of the effects of MS onset type on the overall and disability-severity specific HRQoL scores using a detailed preferentially sensitive AQoL-8D instrument. While overall HRQoL was substantially lower in PROMS than in ROMS, the mean HRQoL values for each disability level did not differ by onset type, indicating that future health economic models can use the same HSU inputs for both onset types.

Abstract
Background: In the CLARITY (CLAdRIbine Tablets treating multiple sclerosis orallY) study of patients with relapsing-remitting multiple sclerosis, treatment with cladribine tablets 3.5 mg/kg (CladT) significantly reduced the annualised relapse rate (ARR) versus placebo; this effect was sustained in CLARITY Extension, without further treatment. Objective: To assess the frequency and severity of relapses in patients treated with CladT versus placebo in CLARITY over 2 years and evaluate the durability of effect in patients who received no further treatment for 2 years in CLARITY Extension. Methods: In this post hoc analysis, ARRs were calculated for qualifying and all relapses, and qualifying and all severe relapses (i.e. requiring steroid treatment or leading to hospitalisation) in patients treated with CladT (n = 433) and placebo (n = 437) in CLARITY, and those from the CladT group who received placebo in CLARITY Extension (n = 98). Results: At Month 6, Year 1 and Year 2, patients receiving CladT had a significantly lower risk of qualifying or all relapses (all p < 0.0001), and qualifying or all severe relapses (all p < 0.005), compared with placebo. This effect was sustained in CLARITY Extension without further treatment. Conclusion: The results show durable efficacy of cladribine tablets 3.5 mg/kg for reducing frequency and severity of relapses in patients with relapsing-remitting multiple sclerosis.

Abstract
The COVID-19 poses an ongoing threat to lives around the world and challenges the existing public health and medical service delivery. The lockdown or quarantine measures adopted to prevent the spread of COVID-19 has caused the interruption in ongoing care and access to medical care including to patients with existing neurological conditions. Besides the passivity, isolation, and withdrawal, patients with neurodegenerative diseases experience difficulties in communication due to a limited access to leisure opportunities and interaction with friends and relatives. The communication difficulties may exacerbate the burden on the caregivers. Therefore, assistive-technologies may be a useful strategy in mitigating challenges associated with remote communication. The current paper presents an overview of the use of assistive technologies using virtual reality and virtual body ownership in providing communication opportunities to isolated patients, during COVID-19, with neurological diseases and moderate-to-severe communication difficulties. We postulate that the assistive technologies-based intervention may improve social interactions in patients with neurodegenerative diseases and acquired brain injury-thereby reducing isolation and improving their quality of life and mental well-being.

Abstract
Background Relapses are common in patients with multiple sclerosis (MS) even after the use of disease-modifying therapies. Repository corticotropin injection (RCI), plasmapheresis (PMP), and intravenous immunoglobulin (IVIg) may be utilized as alternative therapies in the management of MS relapse. There is a lack of health economic studies on these alternative therapies for the acute exacerbations of MS. The objective of this study was to estimate the cost per response of RCI compared with PMP or IVIg from the United States (US) commercial payer perspective. Methods Costs and response rates were sourced from published peer-reviewed observational studies. The cost of care included MS-related inpatient, outpatient, and medication costs. Treatment response was defined as no evidence of additional relapse treatment or procedure claims within 30 days after treatment. The cost per response for each treatment was calculated by dividing the total annual cost of care by the proportion of patients with resolved relapse for each treatment. The incremental cost per response ratio was calculated by dividing the difference in costs and the proportion of responses for RCI versus PMP or IVIg. One-way sensitivity analysis (OWSA) was conducted for both costs and response rates. All included costs were inflated to the 2019 US dollars. Results With a lower total annual cost of care and a higher response rate, RCI had a lower cost per response (US$141,970) compared with PMP or IVIg (US$253,331). RCI had a lower cost per response even when more stringent estimates for RCI were applied in the OWSA. The annual cost of care had a greater influence on the cost per response in the OWSA. Conclusions Based on the estimates from the real-world evidence, our economic evaluation suggests that RCI may have real-world clinical and economic benefits for patients with MS relapse who fail on corticosteroid therapy.

Abstract
Introduction The severity of relapses varies in multiple sclerosis (MS) and may lead to a differential cost burden. This study aimed to characterize the direct healthcare costs associated with relapses in patients with MS by the level of relapse severity. Methods This retrospective analysis used claims data extracted from the MarketScan® Databases from January 1, 2013 to March 31, 2017 (study period January 1, 2012 to March 31, 2018). Adult patients with at least one diagnosis of MS and 12 months of continuous enrollment prior to the first MS diagnosis to 12 months after the index date were included. On the basis of the severity of the relapse, patients were stratified into three cohorts: severe relapse (SR), mild/moderate relapse (MMR), and no relapse (NR). All-cause and MS-related costs were analyzed during the 12-month follow-up period. Group differences were assessed using descriptive and multivariate statistical analyses. Results In total, 8775 patients with MS were analyzed: 6341 (72%) in the NR cohort, 1929 (22%) in the MMR cohort, and 505 (6%) in the SR cohort. Overall, patients were mostly female (76%), mean age was 50 years, and 25% were on a disease-modifying therapy. Mean (standard deviation [SD]) all-cause and MS-related costs among patients with a relapse were higher vs patients without a relapse (all-cause $66,489 [$56,264] vs $41,494 [$48,417]; MS-related $48,700 [$43,364] vs $24,730 [$33,821]). Among patients with a relapse, the mean (SD) all-cause costs were $87,979 [$65,991] vs $60,863 [$51,998] and MS-related costs were $69,586 ($51,187) vs $43,233 [$39,292] for patients in the SR vs MMR cohorts, respectively. A similar trend for increase in cost by relapse severity was observed in the adjusted analysis. Conclusion Total annual all-cause and MS-related costs increased with severity of the relapses. High-efficacy treatments might reduce the severity of the relapses, thereby reducing the cost of care in patients with MS.

Abstract
BACKGROUND Relapse is one of the main features of multiple sclerosis (MS). Corticosteroids are the first line of management during MS relapse. Since tapering or non-tapering prednisolone after corticosteroid pulse has been a controversial issue, this clinical trial is designed to evaluate the efficacy and safety of the tapering regimen. METHODS Having been treated by intravenous methylprednisolone (IVMP) pulse, sixty-six patients with MS-relapse were randomly assigned to receive oral prednisolone tapering (OPT) or placebo. The regimen was administered in line with the study protocol and the dose was tapered over 20 days. Demographics and symptoms, impact on activities of daily living (ADL), and management procedures were recorded according to Assessing Relapse in Multiple Sclerosis (ARMS) Questionnaire. The incidence of adverse events was assessed using the same questionnaire. Patients' disability improvement was assessed using the Extended Disability Scale (EDSS) during relapse, and over the first, third, sixth months following treatment. RESULTS As shown by the results of the questionnaire, 75% reported that their ADL was not or minimally affected by OPT and there was no significant difference in terms of ADL after treatment between the two groups (p=0.3). The effect of treatment on return to the previous state of health (RSH) showed that there were no differences between the two groups of the study (p=0.5). The improvement of disability in the two groups of oral prednisolone and placebo did not indicate a difference in terms of EDSS in the first and third and six months (p = 0.5, p = 0.9, p=0.3, respectively). Also, the occurrence of some side effects such as weight gain (p = 0.000) and increased appetite (p = 0.004) was higher in the OPT group. CONCLUSION The findings of this study revealed that the efficacy of an OPT after a corticosteroid pulse is non-superior to IVMP plus only in case the safety and tolerability profile are comparable.

Abstract
BACKGROUND AND PURPOSE The patient's perspective is becoming increasingly important for endpoints in studies on multiple sclerosis. However, relapse data generated from the patient's perspective in combination with independent documentation by the physician are scarce. Our objective was to compare self-reported relapses by the patient to physician-documented relapses within a routine clinical practice setting of quarterly visits. METHODS Two-year data (n = 1921 patients) were extracted from two prospective, non-interventional, multicentre cohort studies in Germany. The number of relapses independently reported by patients and physicians was analysed. In addition, inter-rater reliability and measures of validity were evaluated. Patterns of associations were investigated in subgroup analysis of sociodemographic, clinical and patient-reported outcome measures. RESULTS Patients and physicians showed good overall agreement [κ = 0.78, 95% confidence interval (CI) 0.76-0.80]. Nevertheless, patients reported, on average, more relapses than physicians during follow-up (0.55 vs. 0.44; P < 0.001). Corresponding annualized relapse rates were 0.38 (95% CI 0.36-0.39) and 0.30 (95% CI 0.29-0.31), respectively. Differences between physicians and patients were particularly pronounced in patient groups with greater disability levels, decreased health-related quality of life or treatment satisfaction. The positive predictive value was 74.01% (95% CI 71.85-76.07), and the negative predictive value was 98.86% (95% CI 98.67-99.03). CONCLUSION Some disagreement on the occurrence of relapses appears in specific patient subgroups, where factors such as pseudo-relapses or confounding factors may have promoted over- or under-reporting.

Abstract
BACKGROUND Relapses are the hallmark of multiple sclerosis (MS). Analyses have shown that the cost of MS increases during periods of relapse. However, results are inconsistent between studies, possibly due to different study designs and the different implications of relapses with respect to patient characteristics. OBJECTIVES The aims were to estimate and describe direct and indirect relapse costs and to determine differences in costs with respect to patient characteristics. Furthermore, we describe the pharmacoeconomic impact during the relapse follow-up. METHODS Data were extracted from two German, multicenter, observational studies applying a validated resource costs instrument. Relapse costs were calculated as the difference in quarterly costs between propensity score (PS)-matched patients with and without relapses (1:1 ratio). For relapse active patients, we additionally calculated the difference between quarterly costs prior to and during relapse and determined costs in the post-relapse quarter. RESULTS Of 1882 patients, 607 (32%) presented at least one relapse. After PS-matching, 597 relapse active and relapse inactive patients were retained. Relapse costs (in 2019 values) ranged between €791 (age 50 + years) and €1910 (disease duration < 5 years). In mildly disabled and recently diagnosed patients, indirect relapse costs (range €1073-€1207) constantly outweighed direct costs (range €591-€703). The increase from prior quarter to relapse quarter was strongest for inpatient stays (+ 366%, €432; p < 0.001), day admissions (+ 228%, €57; p < 0.001), and absenteeism (127%, €463; p < 0.001). In the post-relapse quarter, direct costs and costs of absenteeism remained elevated for patients with relapse-associated worsening. CONCLUSION A recent diagnosis and mild disability lead to high relapse costs. The results suggest the necessity to incorporate patient characteristics when assessing relapse costs.

Visser LA, Louapre C, Uyl-de Groot CA, Redekop WK. Patient needs and preferences in relapsing-remitting multiple sclerosis: A systematic review. Mult Scler Relat Disord 2020; 39:101929. [PMID: 31924590 DOI: 10.1016/j.msard.2020.101929] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2019] [Revised: 10/29/2019] [Accepted: 01/01/2020] [Indexed: 01/12/2023]
Abstract
BACKGROUND Considering the multiple treatments approved for multiple sclerosis (MS) by the Food and Drug Administration (FDA) and European Medicines Agency (EMA), determining a treatment strategy for patients with clinically isolated syndrome (CIS) and relapsing-remitting MS (RRMS) can be challenging. To date, an overview of the needs and preferences of patients at each treatment decision-making moment is lacking. Therefore, the aim of this systematic review is to examine the existing literature about the needs and preferences of patients with CIS and RRMS when making treatment decisions. METHODS A systematic search was done using Embase, Medline, PsychINFO, Web of Science and Google Scholar. Eligibility criteria included whether the article described a study of adults with CIS/RRMS and reported patient needs or preferences regarding first-line disease modifying treatment (DMT) decisions. Publications were categorized by treatment decision: initiation of first DMT (D1), DMT adherence/discontinuation (D2a/D2b), and switch to a second DMT (D3). A separate category was created for stated preference studies such as discrete choice experiment methods to examine the relative importance of different treatment attributes. Publications were compared to identify key factors. RESULTS The search yielded 2789 articles after removal of duplicates and 434 full-text publications were reviewed for eligibility. Twenty-four articles fulfilled all criteria: n = 5 (D1), n = 12 (D2a), n = 13 (D2b), and n = 3 (D3); six articles studied more than one treatment decision. The need for social support is important during D1. The most commonly reported reasons for adherence/discontinuation/switch included forgetfulness, side-effects, and injection-related reasons. Eight articles described preference studies; the most important DMT attributes were efficacy, mode and frequency of administration, and side-effect profile. CONCLUSIONS Understanding the needs and preferences of CIS/RRMS patients regarding DMT attributes and non-treatment related attributes are important to improve treatment decision-making and reduce non-adherence. Studies are needed to understand patient preferences upon treatment initiation. Furthermore, preference studies should include attributes based on the patient perspective.

Abstract
Background The UK Risk Sharing Scheme (RSS) provided information on the effect of first-line multiple sclerosis (MS) disease-modifying treatments on long-term disability. Objective The aim is to provide results specific to glatiramer acetate (GA; Copaxone®) from the final 10-year analysis of the RSS. Methods A Markov model was used to assess clinical effectiveness measured as Expanded Disability Status Scale (EDSS) progression and utility loss. Untreated patients from the British Columbia MS cohort (1980-1995) were used as a 'virtual comparator' group. A separate Markov model assessed cost-effectiveness, based on a 50-year time horizon (with a 50% treatment waning effect imposed at 10 years) and using NHS list price (£513.95 per 28 days). Results were expressed in quality-adjusted life years (QALYs). Results In total, 755 patients with relapsing-remitting MS (RRMS) received GA, with a mean follow-up of 7.1 (standard deviation 1.3) years. EDSS progression was reduced by 23% (progression ratio 76.7, 95% confidence interval [CI] 69.0-84.3) and utility loss by 39% (progression ratio 61.0, 95% CI 52.7-69.3) compared with no treatment. There was no persistent waning in GA treatment effect over time (EDSS: p = 0.093; utilities: p = 0.119). The cost per QALY was £17,841. Conclusion GA had a beneficial effect on long-term disability and was a cost-effective treatment for RRMS.

Abstract
Background Multiple sclerosis (MS) is prevalent among working age individuals (20–60 years), leading to high burden on work productivity. Few data are available about the absenteeism and presenteeism in employed individuals with MS in comparison to non-MS personnel. This study aimed to quantify the burden of illness of employed US adults with relapsing-remitting multiple sclerosis (RRMS) and examine burden by levels of work impairment. Methods A retrospective cross-sectional analysis was conducted using patient-reported responses from the US National Health and Wellness Survey (NHWS). Data from NHWS 2015–2016 were analyzed from 196 employed RRMS respondents who were matched 1:4 to employed respondents without MS based on demographic and general health characteristics. Demographic and general health characteristics for employed RRMS individuals were analyzed by levels of work impairment (none, 1–30%; 31–68%; 69–100%). Work productivity (absenteeism, presenteeism, and work impairment), decrements in health-related quality of life (HRQoL) (short form-36, EQ-5D), and healthcare resource utilization (HCRU) were compared to determine the burden of RRMS. Results After propensity score matching, the levels of absenteeism and presenteeism were 2 and 1.8 times higher in the employed RRMS population than the employed non-MS population, respectively (P < 0.001 for both). HRQoL was significantly lower in employed respondents with RRMS than those without MS (P < 0.001 for all). Employed respondents with RRMS had significantly more HCRU over 6 months compared to those without MS (P < 0.001). Furthermore, among employed RRMS respondents, greater levels of impairment were associated with increasing disease severity, greater healthcare resource use, fatigue, and cognitive impairment and inversely associated with mental and physical HRQoL (P < 0.0001 for all). Conclusions Among employed individuals, respondents with RRMS had lower, work productivity, HRQoL, and higher HCRU as compared with those without MS. Given the large impact RRMS has on work impairment, a need exists to manage individuals on therapies that improve HRQoL, reduce symptoms, and improve their ability to perform in the workforce.

Early initiation of fingolimod reduces the rate of severe relapses over the long term: Post hoc analysis from the FREEDOMS, FREEDOMS II, and TRANSFORMS studies. Mult Scler Relat Disord 2019; 36:101335. [PMID: 31557679 DOI: 10.1016/j.msard.2019.07.011] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2019] [Revised: 06/21/2019] [Accepted: 07/19/2019] [Indexed: 01/16/2023]
Abstract
BACKGROUND Relapse frequency is often correlated with the prognosis of multiple sclerosis (MS). In patients with relapsing-remitting MS (RRMS), relapses vary in severity and may affect activities of daily living, require steroid intervention, or hospitalization. Incomplete recovery from relapses results in increasing disability. In pivotal phase III studies of fingolimod (FREEDOMS, FREEDOMS II, and TRANSFORMS), the frequency of overall and severe relapses was significantly reduced in patients with RRMS treated with fingolimod compared with placebo or intramuscular interferon β-1a (IFN β-1a). The objective of this study was to report the effect of early initiation of fingolimod on relapse severity in patients with RRMS. METHODS This is a post hoc descriptive analysis of data from the pooled placebo-controlled FREEDOMS/FREEDOMS II studies and from the active-comparator TRANSFORMS study. Patients were analyzed under 2 groups: patients initially randomized to receive fingolimod 0.5 mg during the core phase and continued fingolimod 0.5 mg in the extension phase (immediate fingolimod group), and patients initially randomized to placebo or IFN β-1a during the core phase and switched to fingolimod during the extension phase (delayed fingolimod group). Annualized relapse rate (ARR) was estimated for severe relapses (defined as Expanded Disability Status Scale increase of >1 point, or >2-point change in 1 or 2 Functional Systems, respectively, or >1-point change in >4 Functional Systems). ARR was also estimated for relapses that affected activities of daily living, required steroid use, or hospitalization. RESULTS In the pooled FREEDOMS/FREEDOMS II extensions, the immediate fingolimod group showed sustained reductions in the proportion (core: 15.8% and extension: 9.3%) and in ARR over 4 years (0.032 and 0.015) for severe relapses, in relapses requiring steroids (0.149 and 0.123), hospitalization (0.049 and 0.039) and relapses affecting activities of daily living (0.155 and 0.112). In the TRANSFORMS extension, similar reductions were observed in the immedaite group for the proportion of severe relapses (core: 11.8% and extension: 9.8%). ARR remained low over 2 years for severe relapses (0.024 and 0.018), relapses affecting activities of daily living (0.112 and 0.109), relapses requiring steroids (0.156 and 0.161) and hospitalization (0.027 and 0.033). Results in the FREEDOMS/FREEDOMS II and TRANSFORMS extensions for the delayed group were similar. In the TRANSFORMS extension, the proportion of severe relapses were 18.0% (core) and 11.1% (extension); there were significant reductions in ARR for severe relapses (core: 0.079 and extension: 0.029), relapses requiring steroids (0.366 and 0.232), hospitalization (0.092 and 0.055), and relapses affecting activities of daily living (0.285 and 0.144) (all p < 0.0001). Complete recovery was reported for the majority of relapses during the core and extension phases in both the immediate and delayed fingolimod groups (Pooled FREEDOMS/FREEDOMS II: immediate group 59.7%-65.5% and delayed group 64.9%-67.7%; TRANSFORMS: 72.1%-80.0% and 65.4%-70.8%). CONCLUSIONS In patients with RRMS, the frequency of severe relapses and relapse severity remained low in the immedaite fingolimod group over a period of 4 years. Reductions in the proportion of severe relapses post switch from IFN β-1a or placebo to fingolimod underscore the clinical benefit and the relevance of an early initiation of fingolimod.

Abstract
Background Most people with multiple sclerosis (MS) have periodic and unpredictable relapses as part of their disease course. Relapses often affect functional abilities, resulting in diminished productivity and lower quality of life. Considering the effects, rehabilitation can play an important role in facilitating recovery; yet, the current literature suggests a lack of postrelapse rehabilitation services use. This study aims to document postrelapse rehabilitation services use and estimate the extent to which predisposing characteristics, perceived need, and enabling resources were associated with postrelapse rehabilitation services use in adults with MS. Methods This cross-sectional study used convenience sampling, and data from 73 adults with MS who recently had a relapse in the United States and Canada were analyzed. Results A total of 25 participants (34.2%) reported using postrelapse rehabilitation services. The regression model identified three variables associated with postrelapse rehabilitation services use: age (odds ratio [OR], 1.075), self-reported quality of life (considerably affected by the most recent relapse [OR, 5.717]), and presence of helpful health care providers (for obtaining postrelapse rehabilitation services [OR, 5.382]). Conclusions Most participants experienced a range of symptoms or limitations because of their most recent relapse, affecting their daily activity and quality of life. However, only one-third of the participants reported using postrelapse rehabilitation services, which focused on the improvement of their physical health. Regression modeling revealed that three population characteristics of the Andersen Behavioral Model of Health Services Utilization were associated with postrelapse rehabilitation services use.

Abstract
Background and Objective Teriflunomide is a once-daily oral immunomodulatory agent approved in 80 countries for the treatment of patients with relapsing multiple sclerosis (RMS). The study objective was to estimate the cost effectiveness of teriflunomide (14 mg tablet, daily) versus interferon beta-1b (250 mcg subcutaneous injection, every other day) among RMS patients from the Chinese healthcare system perspective. Methods A Markov model with annual cycles and a lifetime horizon was utilized to assess cost-effectiveness of teriflunomide in comparison with interferon beta-1b in RMS patients. Treatment effects, including 3-month confirmed disability worsening and annualized relapse rate, were derived from a network meta-analysis. Cost inputs included costs related to treatment acquisition, administration, monitoring, natural disease management through Expanded Disability Status Scale states, relapse treatment, and adverse event management. These costs were calculated as the product between unit costs from published sources and healthcare resource utilization patterns identified in a survey conducted among 11 neurologists across different areas in China. Health effects were expressed as quality-adjusted life years (QALYs) with costs in local currency (¥) and US dollars (US$), 2018. Results Teriflunomide dominated interferon beta-1b and was associated with lower total costs (teriflunomide ¥1,887,144 vs interferon beta-1b ¥2,061,393) and higher QALYs (teriflunomide 9.60 QALYs vs interferon beta-1b 8.88 QALYs). In probabilistic sensitivity analysis, teriflunomide was dominant in 62.2% of model runs. Conclusion Teriflunomide is a cost-effective therapy over a lifetime time horizon compared to interferon beta-1b in the treatment of RMS patients in China. Results should be interpreted with caution as head-to-head comparisons are not available.

Abstract
BACKGROUND Cost-effectiveness analyses tend not to take into account the availability of lower-priced generics following loss of exclusivity (LOE) of branded products. By not considering these generics, which are typically adopted quickly, total costs are likely to be overestimated and may be unreflective of real-world payer conditions in the United States. OBJECTIVE To assess the impact of including future price reductions following LOE on the cost-effectiveness of fingolimod versus intramuscularly administered interferon beta-1a (IM IFNβ-1a) as treatments for multiple sclerosis. METHODS This model was adopted from a previously published Markov model and was conducted from a U.S. payer perspective over a 10-year time horizon. Patients with relapsing-remitting multiple sclerosis entered the model and received either fingolimod (an oral therapy) or IM IFNβ-1a (an injectable). These treatments reflect the interventions studied in the TRANSFORMS randomized clinical trial. Clinical, cost, and utility inputs were based on a recent cost-effectiveness review of therapies for multiple sclerosis. To model LOE, price reductions and the proportion of patients switching to generic versions following LOE were based on published estimates. Price reductions varied to reflect the difference in product types (oral vs. large molecule injectable). Assumptions were also made around the proportion of patients switching to generic versions over time following LOE and the projected date of LOE. Outcomes included per-patient total direct costs (medication, administration and monitoring, and disease-related costs including relapses), quality-adjusted life-years, and the incremental cost per quality-adjusted life-year. RESULTS Assuming no price reductions following LOE, fingolimod was considered cost-effective versus IM IFNβ-1a ($118,434 per quality-adjusted life-year), despite having higher total direct costs over 10 years ($475,740 vs. $446,792). When including future price reductions following LOE, total direct costs were reduced with fingolimod and were lower than those accrued with IM IFNβ-1a over the model time horizon ($308,570 vs. $442,653). Cost-effectiveness results were sensitive to changes in both clinical parameters and medication costs. Scenario analyses demonstrated that an earlier date of LOE was associated with lower total costs. CONCLUSIONS Health economic models may predict higher total costs when the price reductions following LOE are not considered. Here, oral fingolimod was seen to be cost-saving versus IM IFNβ-1a over the model time horizon when such price reductions were included. The cost implications of not accounting for future price changes may determine whether an intervention is considered cost-effective and as such may influence reimbursement decisions based on cost-effectiveness thresholds. Multiple product types (e.g., oral, injectable, and infused agents) have been approved for use as treatments for multiple sclerosis in the United States, and LOE is likely to have a different effect on each of these therapies.

Abstract
OBJECTIVE To evaluate the efficacy and safety of rituximab for relapsing-remitting multiple sclerosis. RESULTS Fifteen studies that collectively included 946 patients were selected for the meta-analysis. Rituximab therapy was associated with the mean annualized relapse rates decreasing by 0.80 (95% confidence interval, 0.45-1.15) and the mean Expanded Disability Status Scale score decreasing by 0.46 (95% confidence interval, 0.05-0.87). The likelihood of patients experiencing a relapse after starting rituximab therapy was only 15% (95% confidence interval, 7%-26%). Although mild-to-moderate adverse events occurred in 29.6% of the patients, there were no severe adverse events. CONCLUSIONS AND RELEVANCE This systematic review and meta-analysis shows that rituximab is associated with reduced annualized relapse rates and disability levels in patients with relapsing-remitting multiple sclerosis. It is also well tolerated and is not associated with serious adverse events.

Abstract
OBJECTIVE To evaluate the cost-effectiveness of alemtuzumab compared with fingolimod, natalizumab, ocrelizumab, and generic glatiramer acetate 20 mg among patients with relapsing multiple sclerosis (RMS) in the United States. STUDY DESIGN Markov model with annual periods from payer perspective. METHODS The modeled population represented pooled patients from the CARE-MS I and II trials. Therapies' comparative efficacy at reducing relapses and slowing disability worsening was obtained from network meta-analyses. Safety information was extracted from package inserts. Withdrawal rates, treatment waning, resource use, cost, and utility inputs were derived from published studies and clinical expert opinion. To project the natural history of disease worsening, data from the British Columbia cohort was used. RESULTS Alemtuzumab dominated comparators by accumulating higher total quality-adjusted life-years (QALYs) (8.977) and lower total costs ($421 996) compared with fingolimod (7.955; $1 085 814), natalizumab (8.456; $1 048 599), ocrelizumab (8.478; $908 365), and generic glatiramer acetate (7.845; $895 661) over a 20-year time horizon. Alemtuzumab's dominance was primarily driven by savings in treatment costs because alemtuzumab has long-term duration of response and is initially administered as 2 annual courses, with 36.1% of patients requiring retreatment over 5 years, whereas comparators are used chronically. In model scenarios where alemtuzumab's long-term duration of response was assumed not to hold and therapy had to be administered annually, probabilistic sensitivity analyses showed that alemtuzumab remained cost-effective versus ocrelizumab at a willingness-to-pay threshold of $100 000/QALY in 74% to 100% of model runs. CONCLUSIONS Alemtuzumab was a cost-effective therapy. Model results should be used to optimize clinical and managed care decisions for effective RMS treatment.

Benefit evaluation in multiple sclerosis relapse treatment from the patients' perspective - Development and validation of a new questionnaire. Mult Scler Relat Disord 2019; 28:256-261. [PMID: 30639826 DOI: 10.1016/j.msard.2018.12.021] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2018] [Revised: 11/20/2018] [Accepted: 12/15/2018] [Indexed: 11/21/2022]
Abstract
BACKGROUND Little is known on how to measure patient-relevant benefit of relapse treatment in relapsing-remitting multiple sclerosis (MS). The objective of this study was to develop and validate a new method for monitoring recovery from MS relapses and patient-relevant treatment benefits. METHODS A 27-item questionnaire was developed using a multi-step approach comprising open item collection, multidisciplinary expert panel and cognitive debriefing. It was evaluated regarding psychometric properties and feasibility in a longitudinal validation study with 100 patients with MS undergoing relapse treatment. Construct validity was tested by correlations with patient and physician global impressions of change as well as disease-specific and generic health-related quality of life (HRQoL) measures. RESULTS Results of the feasibility survey indicated high patient acceptance. Reliability was high (Cronbach's α = 0.90). While the Expanded Disability Status Scale (EDSS) was not sensitive to change, Patient Benefit Index for Multiple Sclerosis (PBI-MS) showed a high correlation cross-sectionally with patient global impression of change (PaGIC) (r = 0.60, p < 0.001). Significant moderate to high correlations were found with change in generic HRQoL (r = 0.55-0.61, p < 0.001) and lower correlations with change in disease-specific HRQoL (r = -0.36, p < 0.01). CONCLUSION The PBI-MS is a reliable and valid instrument for ascertaining patient-relevant benefits of acute relapse treatment; it appears suited for use in routine care and in clinical or health care studies.

Abstract
BACKGROUND Several disease-modifying therapies (DMTs) treat relapsing-remitting multiple sclerosis (RRMS) and primary progressive multiple sclerosis (PPMS). Few comprehensive cost-effectiveness analyses exist in this area, particularly from a payer perspective, despite rapidly increasing prices of DMTs. OBJECTIVE We aimed to systematically compare cost effectiveness of all relevant DMTs for first-line treatment of RRMS, second-line treatment of RRMS, and first-line treatment of PPMS. METHODS We used a Markov model with health states based on Expanded Disability Status Score categories. Upon discontinuing first-line treatment, RRMS patients continued to second-line therapy then to supportive care, and PPMS patients moved directly to supportive care. Data was sourced from clinical trials and commercially and publicly available sources. The target population was treatment-naïve adults with RRMS or PPMS. We used a lifetime horizon from a US payer perspective, and compared DMTs for RRMS (first-line: dimethyl fumarate, glatiramer acetate, interferon β-1a, interferon β-1b, peginterferon β-1a, teriflunomide, natalizumab, fingolimod, and ocrelizumab; second-line: alemtuzumab, natalizumab, fingolimod, and ocrelizumab), ocrelizumab for PPMS, and supportive care. Outcome measures included total costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs). RESULTS For RRMS first-line therapy, ocrelizumab dominated the other DMTs with an ICER of US$166,338/QALY compared with supportive care. For RRMS second-line therapy, alemtuzumab dominated the other three DMTs, providing more QALYs for lower costs. For PPMS, ocrelizumab had an ICER of US$648,799/QALY compared with supportive care. Wide variability in results was observed in the probabilistic sensitivity analysis. Results were sensitive to the relative risk of progression and cost of DMTs. CONCLUSIONS Ocrelizumab would likely be cost effective as a first-line treatment for RRMS with a discounted price but was not cost effective for PPMS. Alemtuzumab dominated other options for second-line treatment of RRMS. Other DMTs were generally similar in terms of costs and health outcomes, providing health benefits compared to supportive care but with significant added costs. If drug prices were lowered, more DMTs could be cost effective.

Abstract
PURPOSE OF REVIEW This article discusses acute exacerbations (relapses) of multiple sclerosis (MS). Relapses are a hallmark of MS and are often associated with significant functional impairment and decreased quality of life. This review discusses the proposed pathophysiology of MS relapses, triggering factors, associated markers, variants of clinical presentation, and diagnostic recommendations. RECENT FINDINGS Most MS exacerbations are followed by a period of repair leading to clinical remission; however, residual deficits may persist after MS relapse and contribute to the stepwise progression of disability. Treatment of MS relapses is important as it helps to shorten the duration of disability associated with their course. Successful treatment of relapse helps patients with MS obtain a vital sense of being able to gain control over the disease. Patients with relapsing MS who receive treatment report better outcomes than those who are simply observed. This article discusses treatment options for MS relapse, including systemic corticosteroids, adrenocorticotropic hormone, and plasma exchange. Recent findings related to the mechanisms of action of steroids and adrenocorticotropic hormone are also reviewed, and other potential therapies are assessed. A proposed algorithm for MS relapse management is presented, including strategies for steroid-resistant MS exacerbations. SUMMARY MS relapses need to be recognized in a timely manner and treated using recommended therapeutic methods.

Abstract
AIM Disease-modifying therapies (DMTs) impact the natural history of relapsing forms of multiple sclerosis (RRMS) by reducing annual relapse rates and slowing disability progression. The effect of DMTs on indirect costs has not been consistently explored in cost-effectiveness studies thus far. The value to patients of an emerging DMT, ocrelizumab, was quantified in comparison to subcutaneous interferon beta-1a (IFNβSC) for the prevalent RRMS population with mild-to-moderate disability in the US, based on two Phase 3 trials, OPERA I and OPERA II, of ocrelizumab vs IFNβSC in RRMS. MATERIALS AND METHODS A Markov model was developed to compare disability progression as measured by Expanded Disability Status Scale (EDSS) and relapse outcomes over a 30-year horizon for ocrelizumab vs IFNβSC. Direct, indirect, and informal costs (2016 US dollars) and utilities for EDSS health states were obtained from the literature. Hazard ratios for disability progression and relapse rates were estimated from clinical trials. Value was assessed by calculating the net monetary benefit (NMB), defined as the monetary value of discounted quality-adjusted life years (QALYs) minus total costs, where the value of a QALY was $150,000. One-way sensitivity analyses were conducted. RESULTS Ocrelizumab was associated with an incremental gain of 0.84 QALYs and cost savings of $287,713 relative to IFNβSC, resulting in an incremental NMB (INMB) of $413,611 per person over 30 years. The INMB increased by $151,763 for those initiating ocrelizumab at EDSS level 1 vs level 4. Influential parameters were QALY value, treatment costs, and disability progression; however, all sensitivity analyses indicated that the INMB for ocrelizumab relative to IFNβSC was ≥$300,000 per person. CONCLUSIONS Ocrelizumab provides greater value to RRMS patients compared with IFNβSC. Initiating ocrelizumab at lower EDSS levels leads to a greater cumulative value due to slower disability progression, which extends years with higher quality-of-life.

Abstract
Multiple patient-reported outcomes (PROs) are currently being used in multiple sclerosis (MS) but their application is inconsistent and guidance on the appropriateness of each tool is lacking. The objective of our study was to identify MS-specific PROs and systematically to assess the development process and the reliability and validity of various instruments. A systematic literature search was conducted on multiple data sources, including MEDLINE, Embase (using the Ovid platform) and Google Scholar, from 1996 to March 2015. Search terms included combinations of MS, PROs and quality of life. Randomized controlled trials or observational studies conducted on patients with MS and published in English were included. In addition, the PROQOLID database was explored. The MS-specific PROs were systematically assessed using the Evaluating the Measurement of Patient-Reported Outcomes tool. In total, 8094 articles were screened and 405 PROs were identified from 1102 relevant articles. PROs were classified into MS-specific (n = 82) and non-MS-specific (n = 323). The results for the eight PROs that are most commonly used in MS clinical trials are presented here. For these eight PROs, the overall summary scores ranged between 50.1 and 68.7. The Multiple Sclerosis Impact Scale-29 had the best overall mean score (68.7), followed by the Leeds Multiple Sclerosis Quality of Life (67.0). This is the first study to provide a standardized assessment of all PROs for MS. There is a lack of data on content validity for PROs used in MS research, which indicates the need for a robust instrument in MS developed according to the US Food and Drug Administration guidelines.

Abstract
AIM To compare the cost-effectiveness of different disease-modifying therapies' strategies for treatment of relapsing-remitting multiple sclerosis. METHODS A Markov model was developed to assess the cost-effectiveness and incremental cost-effectiveness ratios for different strategies of using disease-modifying therapies from a US third-party payer perspective. All costs were converted to 2014 US$. RESULTS Over 20 years, the total costs per patient were estimated at US$161,136.60 for Strategy 1 (symptom management [SM] alone), US$551,650.66 for Strategy 2 (SM and IFN-β-1a), US$703,463.60 for Strategy 3 (SM and natalizumab) and US$670,985.24 for Strategy 4 (SM and alemtuzumab). The accumulated quality-adjusted life years were 10.49, 10.66, 10.69 and 10.71 for each of the four Strategies 1-4, respectively. The resulting incremental cost-effectiveness ratios were 2,297,141.53 comparing Strategy 2 to Strategy 1, and -1,623,918.00 comparing Strategy 4 to Strategy 3. CONCLUSION Strategy 1 was the cost-effective strategy for treatment of relapsing-remitting multiple sclerosis when compared with other strategies.

Abstract
BACKGROUND Relapses can have a major impact on the lives of people with multiple sclerosis (MS), and yet relapse-related healthcare costs have received little attention. This has limited cost-effectiveness analyses of treatments for MS and hampered decision-making regarding the funding of MS healthcare services. OBJECTIVE To describe health/social care resource use and costs according to the frequency, severity, and endurance of MS relapses. METHODS Data from the prospective, longitudinal UK South West Impact of Multiple Sclerosis cohort were used. A total of 11,800 questionnaires from 1441 people with MS were available, including data on relapses, contacts with health/social care professionals, and other MS-related resource use. RESULTS The mean (SD) 6-monthly MS-related health/social care cost for individuals who reported a relapse was £519 (£949), compared to £229 (£366) for those who had not did report a relapse. Care costs varied widely dependent on the characteristics of the relapse. The mean (SD) cost when a relapse was not treated with steroids was £381 (£780), whilst the equivalent cost was £3579 (£1727) when a relapse resulted in hospitalization. CONCLUSIONS The impact of relapses on health and social care resources and costs differs according to their frequency, length, and severity. The data provided here can be used in cost-effectiveness analyses and to inform decision-making regarding healthcare provision for people with this condition.

Abstract
The aim of this study was to evaluate the efficacy and safety of teriflunomide in reducing the frequency of relapses and progression of physical disability in patients with relapsing multiple sclerosis (RMS). Literatures were searched in Pubmed, Medline and Embase to screen citations from January 1990 to April 2015. Studies of parallel group design comparing teriflunomide and placebo for RMS were screened. After independent review of 234 citations by two authors, seven studies were identified as meeting the inclusion criteria. The results showed teriflunomide (7 and 14mg) could significantly reduce annualized relapse rate and teriflunomide at the higher dose could also decrease the disability progression (risk ratio (RR)=0.69, 95% confidence interval (CI): 0.55-0.87). And teriflunomide significantly reduce annualized rates of relapses with sequelae-EDSS/FS, relapses leading to hospitalization, and relapses requiring IV corticosteroids. Patients treated with teriflunomide 14mg have a lower annualized rate of relapses with sequelae-investigator (RR=0.37, 95% CI: 0.26-0.52). Teriflunomide 7mg has a higher incidence of diarrhea (RR=1.73, 95% CI: 1.32-2.26) and hair thinning (RR=1.99, 95% CI: 1.4-2.81), while teriflunomide 14mg has a higher incidence of diarrhea (RR=1.71, 95% CI: 1.34-2.18), hair thinning (RR=2.81, 95% CI: 2.02-3.91) and nausea (RR=1.65, 95% CI: 1.03-2.31) compared with placebo. The incidence of elevated alanine aminotransferase levels was also higher with teriflunomide than with placebo. However, the incidence of serious adverse events was similar across groups. In conclusion, teriflunomide significantly reduces annualized relapse rates and disability progression with a similar safety and tolerability profile to placebo.

Abstract
BACKGROUND Cost-of-illness (COI) studies of Multiple Sclerosis (MS) are vital components for describing the economic burden of MS, and are frequently used in model studies of interventions of MS. We conducted a systematic review of studies estimating the COI of MS, to compare costs between studies and examine cost drivers, emphasizing generalizability and methodological choices. MATERIAL AND METHOD A literature search on studies published in English on COI of MS was performed in PubMed for the period January 1969 to January 2014, resulting in 1,326 publications. A mapping of studies using a bottom-up approach or top-down approach, respectively, was conducted for the 48 studies assessed as relevant. In a second analysis, the cost estimates were compared between the 29 studies that used a societal perspective on costs, human capital approach for indirect costs, presenting number of patients included, time-period studied, and year of price level used. RESULTS The mapping showed that bottom-up studies and prevalence approaches were most common. The cost ratios between different severity levels within studies were relatively stable, to the ratio of 1 to 2 to 3 for disability level categories. Drugs were the main cost drivers for MS-patients with low disease severity, representing 29% to 82% of all costs in this patient group, while the main cost components for groups with more advanced MS symptoms were production losses due to MS and informal care, together representing 17% to 67% of costs in those groups. CONCLUSION The bottom-up method and prevalence approach dominated in studies of COI of MS. Our findings show that there are difficulties in comparing absolute costs across studies, nevertheless, the relative costs expressed as cost ratios, comparing different severity levels, showed higher resemblance. Costs of drugs were main cost drivers for less severe MS and informal care and production losses for the most severe MS.

Abstract
INTRODUCTION We present international consensus recommendations for improving diagnosis, management and treatment access in multiple sclerosis (MS). Our vision is that these will be used widely among those committed to creating a better future for people with MS and their families. METHODS Structured discussions and literature searches conducted in 2015 examined the personal and economic impact of MS, current practice in diagnosis, treatment and management, definitions of disease activity and barriers to accessing disease-modifying therapies (DMTs). RESULTS Delays often occur before a person with symptoms suggestive of MS sees a neurologist. Campaigns to raise awareness of MS are needed, as are initiatives to improve access to MS healthcare professionals and services. We recommend a clear treatment goal: to maximize neurological reserve, cognitive function and physical function by reducing disease activity. Treatment should start early, with DMT and lifestyle measures. All parameters that predict relapses and disability progression should be included in the definition of disease activity and monitored regularly when practical. On suboptimal control of disease activity, switching to a DMT with a different mechanism of action should be considered. A shared decision-making process that embodies dialogue and considers all appropriate DMTs should be implemented. Monitoring data should be recorded formally in registries to generate real-world evidence. In many jurisdictions, access to DMTs is limited. To improve treatment access the relevant bodies should consider all costs to all parties when conducting economic evaluations and encourage the continuing investigation, development and use of cost-effective therapeutic strategies and alternative financing models. CONCLUSIONS The consensus findings of an international author group recommend a therapeutic strategy based on proactive monitoring and shared decision-making in MS. Early diagnosis and improved treatment access are also key components.

Abstract
BACKGROUND Fingolimod is a once-daily, orally administered therapy for relapsing forms of MS. It has been shown to reduce relapse rates significantly in all phase II and phase III clinical trials when compared with placebo and intramuscular interferon β-1a (IFNβ-1a IM). METHODS This study compared annualized relapse rates (ARRs) associated with fingolimod, placebo and IFNβ-1a IM, in patient subgroups from the pooled FREEDOMS, FREEDOMS II, and TRANSFORMS populations. This provided a large data set in which the efficacy of fingolimod could be assessed across a range of patient subgroups, including clinically relevant subgroups not previously analysed. RESULTS Compared with placebo, fingolimod was associated with significantly lower ARRs across all patient subgroups with relative reductions in ARRs ranging from 35% (patients who had previously received treatment for their MS for up to 1 year; P<0.05) to 69% (patients with symptoms for less than 3 years before study entry; P<0.001). Other relative reductions in ARR compared with placebo included 64% in patients aged 40 years or younger and 63% in those naïve to treatment (P<0.001 for both). Compared with IFNβ-1a IM, the greatest benefits to ARR were seen in patients aged 40 years or younger (55% relative ARR reduction, P<0.001) and in a small subgroup of patients who had previously received IFNβ and glatiramer acetate (55% relative ARR reduction; P<0.05). Reductions in ARR compared with IFNβ-1a IM were not statistically significant in men (33%, P=0.081), in patients aged over 40 years (23%, P=0.230) and in those who had received treatment prior to the study for 1 year or less (35%, P=0.108). Fingolimod was associated with significantly lower ARRs compared with placebo and with IFNβ-1a IM irrespective of treatment status (treatment-naïve and previously treated for MS), and regardless of type of previous therapy. CONCLUSIONS Fingolimod provided consistent efficacy benefits over placebo and IFNβ-1a IM across a range of subgroups of patients with relapsing MS. The magnitude of the beneficial effect of fingolimod over IFNβ-1a IM may depend on age, sex, and duration of previous treatment. These findings suggest that most benefit will be gained by patients who start fingolimod early in the disease course, but the findings also suggest that fingolimod treatment will benefit patients later in the disease course when they have already accrued disability.

Patient-reported adverse effects of high-dose intravenous methylprednisolone treatment: a prospective web-based multi-center study in multiple sclerosis patients with a relapse. J Neurol 2016; 263:1641-51. [PMID: 27272956 PMCID: PMC4971042 DOI: 10.1007/s00415-016-8183-3] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2016] [Revised: 05/24/2016] [Accepted: 05/24/2016] [Indexed: 12/03/2022]
Abstract
In a prospective multi-center observational study, we evaluated the frequency, severity, and impact on activities of daily living (ADL) of adverse effects (AEs) of high-dose intravenous methylprednisolone (IVMP) in relapsing remitting multiple sclerosis (MS) patients with a relapse. Online self-report questionnaires stating IVMP’s most common AEs were completed at baseline, the 2nd day of treatment, and 1 day and 1 week after treatment. Eighty-five patients were included, 66 completed the baseline questionnaire, and 59 completed at least one post-baseline questionnaire. Patients reported on average 4 (median) AEs; two (3.4 %) reported no AE. Most frequent was change in taste (61 %), facial flushing (61 %), sick/stomach pain (53 %), sleep disturbance (44 %), appetite change (37 %), agitation (36 %), and behavioral changes (36 %). Of all AEs, 34.3 % were severe and 37.9 % impacted on ADL. A 3-day course resulted in 4 (median) AEs and a 5-day course in 7. All patients with high disease impact had two or more AEs, compared with 79 % of those with low impact (p < 0.01). Of patients with high disability, 45 % had severe AEs, compared with 16 % of those with low disability. Severe central nervous system (CNS)-related AEs occurred two times more frequently in patients with high disease impact, and two-and-a-half times more frequently in patients with high disability. Therefore, in virtually all patients, high-dose IVMP leads to AEs, with about one of three AEs being severe with impact on ADL. Patients with high disease impact or high disability may experience more (severe) AEs, due to a higher occurrence of severe CNS-related AEs.

Abstract
OBJECTIVES To estimate health state utility values (HSUVs) for multiple sclerosis (MS) by key demographic and clinical characteristics. METHODS Data from a UK prospective, longitudinal, cohort study of people with MS were used for analysis. Patient-reported outcomes on the EuroQol five-dimensional questionnaire (EQ-5D) and the six-dimensional health state short form (SF-6D) (derived from 36-item short form health survey), SF-36 were used to estimate HSUVs by age, sex, MS type, time since diagnosis, disease severity (Expanded Disability Status Scale score), and relapse characteristics. RESULTS The cohort (n = 1,441) (11,778 returned questionnaires) was representative of the UK population with MS. Data indicated that primary and secondary progressive MS were associated with lower HSUVs than relapsing-remitting MS and that HSUVs decreased by disease severity. This was particularly apparent for the EQ-5D, with mean estimates ranging from 0.846 to 0.025 for Expanded Disability Status Scale scores 0 to 8, compared to mean SF-6D estimates ranging from 0.702 to 0.529. Experiencing a relapse in the previous 6 months had a significant impact on HSUVs, with mean decrements of 0.076 for the EQ-5D and 0.052 for the SF-6D. CONCLUSIONS These findings demonstrate the negative impact of MS on health-related quality of life, especially as the condition progresses, and indicate the substantial influence of varying features of relapses on HSUVs. This is the first report of SF-6D values for a UK MS population and the first time that EQ-5D data have been presented in such detail for people with MS. The representative nature of the sample means that these data can be used to offer decision makers more precise estimates of the effectiveness and cost-effectiveness of MS treatments.

Abstract
BACKGROUND This is an update of the Cochrane review "Teriflunomide for multiple sclerosis" (first published in The Cochrane Library 2012, Issue 12).Multiple sclerosis (MS) is a chronic immune-mediated disease of the central nervous system. It is clinically characterized by recurrent relapses or progression, or both, often leading to severe neurological disability and a serious decline in quality of life. Disease-modifying therapies (DMTs) for MS aim to prevent occurrence of relapses and disability progression. Teriflunomide is a pyrimidine synthesis inhibitor approved by both the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA) as a DMT for adults with relapsing-remitting MS (RRMS). OBJECTIVES To assess the absolute and comparative effectiveness and safety of teriflunomide as monotherapy or combination therapy versus placebo or other disease-modifying drugs (DMDs) (interferon beta (IFNβ), glatiramer acetate, natalizumab, mitoxantrone, fingolimod, dimethyl fumarate, alemtuzumab) for modifying the disease course in people with MS. SEARCH METHODS We searched the Cochrane Multiple Sclerosis and Rare Diseases of the CNS Group Specialised Trials Register (30 September 2015). We checked reference lists of published reviews and retrieved articles and searched reports (2004 to September 2015) from the MS societies in Europe and America. We also communicated with investigators participating in trials of teriflunomide and the pharmaceutical company, Sanofi-Aventis. SELECTION CRITERIA We included randomized, controlled, parallel-group clinical trials with a length of follow-up of one year or greater evaluating teriflunomide, as monotherapy or combination therapy, versus placebo or other approved DMDs for people with MS without restrictions regarding dose, administration frequency and duration of treatment. DATA COLLECTION AND ANALYSIS We used the standard methodological procedures of Cochrane. Two review authors independently assessed trial quality and extracted data. Disagreements were discussed and resolved by consensus among the review authors. We contacted the principal investigators of included studies for additional data or confirmation of data. MAIN RESULTS Five studies involving 3231 people evaluated the efficacy and safety of teriflunomide 7 mg and 14 mg, alone or with add-on IFNβ, versus placebo or IFNβ-1a for adults with relapsing forms of MS and an entry Expanded Disability Status Scale score of less than 5.5.Overall, there were obvious clinical heterogeneities due to diversities in study designs or interventions and methodological heterogeneities across studies. All studies had a high risk of detection bias for relapse assessment and a high risk of bias due to conflicts of interest. Among them, three studies additionally had a high risk of attrition bias due to a high dropout rate and two studies had an unclear risk of attrition bias. The studies of combination therapy with IFNβ (650 participants) and the study with IFNβ-1a as controls (324 participants) also had a high risk for performance bias and a lack of power due to the limited sample.Two studies evaluated the benefit and the safety of teriflunomide as monotherapy versus placebo over a period of one year (1169 participants) or two years (1088 participants). A meta-analysis was not conducted. Compared to placebo, administration of teriflunomide at a dose of 7 mg/day or 14 mg/day as monotherapy reduced the number of participants with at least one relapse over one year (risk ratio (RR) 0.72, 95% confidence interval (CI) 0.59 to 0.87, P value = 0.001 with 7 mg/day and RR 0.60, 95% CI 0.48 to 0.75, P value < 0.00001 with 14 mg/day) or two years (RR 0.85, 95% CI 0.74 to 0.98, P value = 0.03 with 7 mg/day and RR 0.80, 95% CI 0.69 to 0.93, P value = 0.004 with 14 days). Only teriflunomide at a dose of 14 mg/day reduced the number of participants with disability progression over one year (RR 0.55, 95% CI 0.36 to 0.84, P value = 0.006) or two years (RR 0.74, 95% CI 0.56 to 0.96, P value = 0.02). When taking the effect of drop-outs into consideration, the likely-case scenario analyses still showed a benefit in reducing the number of participants with at least one relapse, but not for the number of participants with disability progression. Both doses also reduced the annualized relapse rate and the number of gadolinium-enhancing T1-weighted lesions over two years. Quality of evidence for relapse outcomes at one year or at two years was low, while for disability progression at one year or at two years was very low.When compared to IFNβ-1a, teriflunomide at a dose of 14 mg/day had a similar efficacy to IFNβ-1a in reducing the proportion of participants with at least one relapse over one year, while teriflunomide at a dose of 7 mg/day was inferior to IFNβ-1a (RR 1.52, 95% CI 0.87 to 2.67, P value = 0.14; 215 participants with 14 mg/day and RR 2.74, 95% CI 1.66 to 4.53, P value < 0.0001; 213 participants with 7 mg/day). However, the quality of evidence was very low.In terms of safety profile, the most common adverse events associated with teriflunomide were diarrhoea, nausea, hair thinning, elevated alanine aminotransferase, neutropenia and lymphopenia. These adverse events had a dose-related effects and rarely led to treatment discontinuation. AUTHORS' CONCLUSIONS There was low-quality evidence to support that teriflunomide at a dose of 7 mg/day or 14 mg/day as monotherapy reduces both the number of participants with at least one relapse and the annualized relapse rate over one year or two years of treatment in comparison with placebo. Only teriflunomide at a dose of 14 mg/day reduced the number of participants with disability progression and delayed the progression of disability over one year or two years, but the quality of the evidence was very low. The quality of available data was too low to evaluate the benefit teriflunomide as monotherapy versus IFNβ-1a or as combination therapy with IFNβ. The common adverse effects were diarrhoea, nausea, hair thinning, elevated alanine aminotransferase, neutropenia and lymphopenia. These adverse effects were mostly mild-to-moderate in severity, but had a dose-related effect. New studies of high quality and longer follow-up are needed to evaluate the comparative benefit of teriflunomide on these outcomes and the safety in comparison with other DMTs.

Abstract
PURPOSE The purpose of this study was to compare the rates of secondary health conditions in individuals with multiple sclerosis (MS) with age-matched U.S. general population norms. METHOD This was a cross-sectional study in which data were collected using a Web-based survey from members of the greater Midwest MS society chapter. Questions were modeled from the National Health Interview Survey to assess the presence of six health conditions. Self-reported health conditions among the sample were compared to U.S. general population norms from the National Health Interview Survey. RESULTS Individuals with MS reported higher rates of depression, arthritis, diabetes, coronary artery disease, migraine headaches, and cancer than the normative population. Although the rates of health conditions increased with age in the normative sample, the MS sample showed a curvilinear (bimodal) pattern as a function of age for some secondary health conditions.

Abstract
OPINION STATEMENT Telemedicine (TM) is defined as the exchange of medical information between two different physical places. The aims of TM are to provide services that cannot easily be provided face-to-face and improve the efficiency of existing ones. Multiple sclerosis (MS) is a chronic demyelinating disease characterized by a heterogeneous array of symptoms that can lead to severe impairment and may impact on accessibility to medical services, patient's ability to function, and overall health-related quality of life (HRQoL). The use of TM to clinically monitor MS patients has demonstrated benefits by improving HRQoL and reducing associated medical costs. Patient-reported outcome (PRO) measures have been used in TM interventions, registries, and cost-efficiency studies because they offer valuable information about patient's perspective of MS disease burden. Moreover, TM has shown acceptable reliability in the assessment of the neurological impairment by Kurtzke expanded disability status scale (EDSS) and has the potential to develop more sensitive measures, such as average daily walking activity, to closely monitor MS disease progression in real environment. It is likely that the use of TM will continue to increase in the following years but larger and controlled studies are necessary to confirm the beneficial effects of TM to deliver an optimal care for patients with MS.

Abstract
Individuals with multiple sclerosis (MS) may experience symptoms that impact comorbid conditions and quality of life (QOL). There is some evidence that symptom severity may vary in certain common health conditions in this population. We aimed to examine symptom severity in light of comorbid conditions commonly seen in individuals with MS (N = 339). Using a cross-sectional Internet survey, we found there was a significant increase in symptom severity of common symptoms of fatigue, imbalance, and weakness, specifically with presence or absence of certain comorbid conditions (depression, arthritis, migraine headaches, coronary artery disease [CAD]). These findings endorse the presence of more severe symptoms with certain comorbid conditions compared with individuals with MS who do not report having comorbid conditions. The findings support the importance of symptom management in individuals with MS who also have comorbid conditions.
