Cost and effectiveness of autologous haematopoietic stem cell transplantation and high-efficacy disease-modifying therapies in relapsing-remitting multiple sclerosis.

BACKGROUND: Autologous haematopoietic stem cell transplantation (AHSCT) is a highly effective one-off treatment for relapsing-remitting multiple sclerosis (RR-MS), potentially representing an optimal front-loading strategy for costs. OBJECTIVE: Exploring cost/effectiveness of AHSCT and high-efficacy disease-modifying treatments (HE-DMTs) in RR-MS, estimating costs at our centre in Italy, where National Health Service (NHS) provides universal health coverage. METHODS: Costs (including drugs, inpatient/outpatient management) for treatment with AHSCT and HE-DMTs were calculated as NHS expenditures over 2- and 5-year periods. Cost-effectiveness for each treatment was estimated as "cost needed to treat" (CNT), i.e. expense to prevent relapses, progression, or disease activity (NEDA) in one patient over n-years, retrieving outcomes from published studies. RESULTS: Costs of AHSCT and HE-DMTs were similar over 2 years, whereas AHSCT was cheaper than most HE-DMTs over 5 years (€46 600 vs €93 800, respectively). When estimating cost-effectiveness of treatments, over 2 years, mean CNT of HE-DMTs for NEDA was twofold that of AHSCT, whereas it was similar for relapses and disability. Differences in CNT were remarkable over 5 years, especially for NEDA, being mean CNT of HE-DMTs €382 800 vs €74 900 for AHSCT. CONCLUSIONS: AHSCT may be highly cost-effective in selected aggressive RR-MS. Besides priceless benefits for treated individuals, cost-savings generated by AHSCT may contribute to improving healthcare assistance at a population level.

Cost associated with a relapse-free patient in multiple sclerosis: A real-world health indicator.

BACKGROUND: The efficacy and safety of disease-modifying therapies (DMTs) in multiple sclerosis (MS) are well known; however, owing to their high costs, determining real-world outcomes is essential to evaluate the cost-effectiveness of different therapeutic strategies. This study aimed to investigate the variability in the annual cost of DMTs associated with a relapse-free patient in a representative population cohort of relapsing-remitting MS (RRMS), and whether this could serve as an appropriate health indicator. METHODS: We analyzed the patients followed up in our MS clinic during the years 2016 and 2019, and selected patients belonging to our health district diagnosed with RRMS. The treatment cost associated with a relapse-free patient was the ratio between the total cost of DMTs and the number of relapse-free patients, treated and not treated, during the year of the study. RESULTS: A total of 158 patients with RRMS in 2016 and 183 in 2019 were included in our study. In 2016, 101 patients with RRMS (63.9%) received treatment with DMTs and 120 patients (75.9%) remained relapse-free. The mean cost of DMTs per patient in 2016 was €7414.3 (95% confidence interval [CI]: 6325.2-8503.4) considering all the patients (treated and not treated). In 2019, 126 patients (68.9%) received DMTs and 151 patients (82.5%) remained relapse-free. The mean cost of DMTs per patient in 2019 was €6985.4 (95% CI: 5986.9-7983.9) considering all the patients. The cost per year of DMTs to achieve a relapse-free patient was €9762.2 in 2016 and €8465.8 in 2019. CONCLUSIONS: The treatment cost per year to achieve a relapse-free patient was stable during successive measurements in the same population. Therefore, it may be considered a good real-world health indicator for patients with RRMS treated with DMTs.

Results from SPECTRUM: A survey of healthcare professionals to understand current diagnosis and management practices for secondary progressive multiple sclerosis in the United Kingdom.

BACKGROUND: Recognising the transition from relapsing remitting multiple sclerosis (RRMS) to secondary progressive MS (SPMS) in clinical practice can be challenging. With disease-modifying therapies (DMTs) commonly used for RRMS accepted to be less efficacious once progression has occurred, treatment options for progressive forms of MS have been limited. Emergence of new DMTs in SPMS are changing the treatment landscape. There is a need to better understand current practice and the factors underlying it, to facilitate consensus on the overall management of SPMS and optimise diagnostic and management decisions. This survey project aimed to assess current practices for the diagnosis and management of patients with SPMS in the UK. METHODS: Healthcare professionals (HCPs) involved in the management of patients with SPMS from geographically distributed MS neurology centres in the UK participated in face-to-face or telephone interviews, facilitated by a semi-structured questionnaire. The survey data were descriptively analysed using quantitative and qualitative methods. RESULTS: Fifty-nine HCPs (41 neurologists, 15 specialist nurses and 3 'other'), from 59 UK centres took part. Sixty-one percent (n = 36/59) of respondents applied a specific definition for SPMS, although only 6% of these (2/36) used the Lublin 2014 phenotype criteria. Expanded Disability Status Scale (EDSS) score increase with an absence of relapses was an important consideration for SPMS diagnosis for 83% (n = 49/59) of respondents, and 36% (n = 21/59) considered this to be the most important piece of evidence that they look for when they suspect a patient is transitioning from RRMS to SPMS. The median (interquartile range [IQR]) estimated time between first suspicion and diagnosis of SPMS was 12 months (12-24 [n = 45/59]), with concerns over withdrawing DMTs and the psychological impact of a diagnosis on patients the most commonly reported reasons for reluctance to diagnose. Seventy-three percent (n = 43/59) of respondents followed specific guidelines for DMT management of patients transitioning from RRMS to SPMS, with most (86%, n = 37/43) using the NHS England algorithm. Ninety-eight percent (n = 58/59) use DMTs to treat patients they suspect may be transitioning to SPMS, and 51% (n = 30/59) reported using DMTs for newly diagnosed SPMS patients. Approximately 1 in 5 HCPs may consider continuing DMTs beyond EDSS 7.0 in certain circumstances. CONCLUSION: The survey highlighted variation across the UK in SPMS definition, diagnosis and reported real-world management. Disparity in practice may result in unnecessary variations in treatment patterns and consequently outcomes. HCPs should be equipped to make timely and accurate decisions, which will be important in improving access to appropriate therapies for patients with SPMS.

Economic burden of highly active relapsing-remitting multiple sclerosis patients in the French national health insurance database.

BACKGROUND: As healthcare management of highly active-relapsing-remitting multiple sclerosis (HA-RRMS) patients is more complex than for the whole multiple sclerosis (MS) population, this study assessed the related economic burden from a National Health Insurance's (NHI's) perspective. RESEARCH DESIGN AND METHODS: Study based on French NHI databases, using individual data on billing and reimbursement of outpatient and hospital healthcare consumption, paid sick leave and disability pension, over 2010-2017. RESULTS: Of the 9,596 HA-RRMS adult patients, data from 7,960 patients were analyzed with at least 2 years of follow-up. Mean annual cost/patient was €29,813. Drugs represented 40% of the cost, hospital care 33%, disability pensions 9%, and all healthcare professionals' visits combined 8%. Among 3,024 patients under 60 years-old with disability pension, disability pension cost €7,168/patient/year. Among 3,807 patients with paid sick leave, sick leave cost €1,956/patient/year. Mean costs were €2,246/patient higher the first year and increased by €1,444 between 2010 and 2015, with a €5,188 increase in drug-related expenditures and a €634 increase in healthcare professionals' visits expenditures but a €4,529 decrease in hospital care expenditures. CONCLUSIONS: The cost of health care sick leaves, and disability pensions of HA-RRMS patients was about twice as high as previously reported cost of MS patients.

Improving quality, affordability, and equity of multiple sclerosis care.

OBJECTIVE: The prevailing approaches to selecting multiple sclerosis (MS) disease modifying therapies (DMTs) have contributed to exponential increases in societal expenditures and out-of-pocket expenses, without compelling evidence of improved outcomes. Guidance is lacking regarding when and in whom the benefits of preventing MS-related disability likely outweighs the risks of highly effective DMTs (HET) and when it is appropriate to consider DMT costs. Our objective was to develop a standardized approach to improve the quality, affordability and equity of MS care. METHODS: MS experts partnered with health plan pharmacists to develop an ethical, risk-stratified, cost-sensitive treatment algorithm. We developed a risk-stratification schema to classify patients with relapsing forms of MS as high, intermediate or low risk of disability based on the best available evidence and, when the evidence was poor or lacking, by consensus. DMTs are grouped as highly, modestly or low/uncertain effectiveness and preferentially ranked within groups by safety based on pre-specified criteria. We reviewed FDA documents and the published literature. When efficacy and safety are equivalent, the lower cost DMT is preferred. RESULTS: Assignment to the high-risk group prompts treatment with preferred HETs early in the disease course. For persons in the intermediate- or low-risk groups with cost or health care access barriers, we incorporated induction therapy with an affordable B-cell depleting agent. Based on more favorable safety profiles, our preferred approach prioritizes use of rituximab and natalizumab among HETs and interferon-betas or glatiramer acetate among modestly effective agents. INTERPRETATION: The risk-stratified treatment approach we recommend provides clear, measurable guidance in whom and when to prescribe HETs, when to prioritize lower cost DMTs and how to accommodate persons with MS with cost or other barriers to DMT use. It can be adapted to other cost structures and updated quickly as new information emerges. We recommend that physician groups partner with health insurance plans to adapt our approach to their settings, particularly in the United States. Future studies are needed to resolve the considerable uncertainty about how much variability in prognosis specific risk factors explain.

Health economics and patient outcomes of hematopoietic stem cell transplantation versus disease-modifying therapies for relapsing remitting multiple sclerosis in the United States of America.

OBJECTIVE: To estimate differences in treatment costs and health outcomes between non-myeloablative hematopoietic stem cell transplantation (HSCT) and disease-modifying therapies (DMTs) for the treatment of relapsing-remitting multiple sclerosis (RRMS). METHODS: We collected data on costs and reimbursements for patients who underwent HSCT for RRMS at Northwestern Memorial Hospital in Chicago (USA) between January 2017 and January 2019. The costs of HSCT were compared against those for DMTs in the United States, obtained from the literature. We also conducted a literature review to interpret the cost comparisons in terms of disease control and patients' wellbeing defined as no evidence of disease activity (NEDA), neurologic disability by the Expanded Disability Status Scale (EDSS), and quality of life by the short form SF-36, respectively. RESULTS: Outside of the data, herein, no other studies on cost of HSCT for RRMS were found in the literature. HSCT mean total costs, based on our own hospital, were $85,184 (range $70,635 to $120,260). Mean revenue collected was $95,268 (range $16,544 to $173,204). In comparison, according to the literature, 2019 DMT costs in the USA ranged from $80,000 to $100,000 per year per patient. Compared to DMTs, studies of HSCT reported greater improvement in no evidence of disease activity, disability, and quality of life. LIMITATIONS: Costs of HSCT would be expected to vary by conditioning regimen utilized, patient selection, center experience, and regional variation. No cost data on other HSCT regimens or on the three most recently licensed DMTs, alemtuzumab, ocrelizumab, and cladribine, are available. Randomized trials for cost comparisons are missing and variations in HSCT designs, populations, and methodology preclude more precise cost estimates. CONCLUSION: Costs of non-myeloablative HSCT after which DMTs are indefinitely discontinued, are approximately the same cost as those for one year of prescription DMTs. Since DMTs assessed in this analysis are given on an ongoing basis, whilst HSCT is not, HSCT is expected to produce long-term cost-savings. When considered alongside the available clinical evidence, which suggests that HSCT may generate more health gains than DMTs, HSCT is likely to represent a cost-effective use of resources. Model-based health economic analyses are required to substantiate this conclusion.

The impact of diagnostic criteria and treatments on the 20-year costs for treating relapsing-remitting multiple sclerosis.

OBJECTIVE: To assess whether the introduction of the new diagnostic criteria and disease modifying therapies (DMTs) is associated with higher cost for treating multiple sclerosis (MS). METHODS: This is a regression-based quasi-experimental study employing interrupted time series analysis, including data from 2229 patients (age 42.1 ±â€¯11.2 years; female 63.34%), with incident diagnosis of relapsing remitting MS (RRMS) and followed up from 1997 to 2017, extracted from the database of the MS Clinical Care and Research Centre of the Federico II University Hospital of Naples (Italy). Annual healthcare costs for DMT (e.g., prescription, staff involved in DMT administration) and management (e.g., neurological consultations, other consultations related to DMT safety, MRI, laboratory exams), were calculated and inflated to the most recent value. RESULTS: Annual costs per patient for DMT prescription and management were not affected by the introduction of 2001 and 2005 criteria, but decreased by 0.4% after the introduction of 2011 criteria (PD= -0.4%; 95% C.I. -0.7%/-0.0%; p = 0.023). Annual costs per patient increased by 11.2% after the introduction of Natalizumab in 2007 (PD= 11.2%; 95% C.I.= 9.4%/13.0%; p <0.001), by 10.9% after the introduction of tablets in 2011 (Fingolimod, Teriflunomide and Dimethyl Fumarate) (PD= 10.9%; 95% C.I. 9.2%/12.7%; p<0.001), and by 10.7% after the introduction of Alemtuzumab in 2015 (PD= 10.7%; 95% C.I. 9.0%/12.4%; p< 0.001). DISCUSSION: DMTs remain the main responsible for increased medical direct costs in MS, whilst improved diagnostic skills and subsequent patient profiling can at least in part mitigate costs for MS treatment and management.

Disease-Modifying Therapies for Relapsing-Remitting and Primary Progressive Multiple Sclerosis: A Cost-Utility Analysis.

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 ß-1a, interferon ß-1b, peginterferon ß-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.

Multimodal assessment of normal-appearing corpus callosum is a useful marker of disability in relapsing-remitting multiple sclerosis: an MRI cluster analysis study.

BACKGROUND AND PURPOSE: Corpus callosum (CC) is frequently involved in relapsing-remitting multiple sclerosis (RRMS). Magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI) allow to study CC macrostructural and microstructural tissue integrity. Here, we applied a data-driven approach to MRI and DTI data of normal-appearing CC in RRMS subjects, and subsequently evaluated if differences in tissue integrity corresponded to different levels of physical disability and cognitive impairment. METHODS: 74 RRMS patients and 20 healthy controls (HC) underwent 3 T MRI and DTI. Thickness and fractional anisotropy (FA) along midsagittal CC were extracted, and values from RRMS patients were fed to a hierarchical clustering algorithm. We then used ANOVA to test for differences in clinical and cognitive variables across the imaging-based clusters and HC. RESULTS: We found three distinct MRI-based subgroups of RRMS patients with increasing severity of CC damage. The first subgroup showed callosal integrity similar to HC (Cluster 1); Cluster 2 had milder callosal damage; a third subgroup showed the most severe callosal damage (Cluster 3). Cluster 3 included patients with longer disease duration and worst scores in Expanded Disability Status Scale. Cognitive domains of verbal memory, executive functions and processing speed were impaired in Cluster 3 and Cluster 2 compared to Cluster 1 and HC. CONCLUSIONS: Within the same homogeneous cohort of patients, we could identify three neuroimaging RRMS clusters characterized by different involvement of normal-appearing CC. Interestingly, these corresponded to three distinct levels of clinical and cognitive disability.

Betainterferonas no tratamento da esclerose múltipla remitente-recorrente (EMRR) / Betainterferones in the treatment of relapsing-remitting multiple sclerosis (RSGR)

Contexto: A esclerose múltipla (EM) é uma condição inflamatória desmielinizante, de origem autoimune que acomete prejuízos na condução do impulso elétrico no sistema nervoso central (SNC). De caráter progressivamente incapacitante, afeta aspectos físicos, psicossociais e econômicos não só do paciente, como também de sua família e da sociedade. Apesar da existência de outras formas, o tratamento com betainterferonas é preconizado apenas para as formas remitente-recorrente (EMRR) e secundariamente progressiva (EMSP), não havendo evidências de benefício para as demais. Após a constatação na literatura de evidências sobre possíveis diferenças de efetividade entre as betainterferonas no tratamento da EMRR, o Ministério da Saúde, por meio da Secretaria de Ciência, Tecnologia e Insumos Estratégicos (SCTIE/MS), buscou avaliar os dados científicos e clínicos sobre o desempenho dessa classe terapêutica na EMRR para sua posterior análise pela Comissão Nacional de Incorporação de Tecnologias no SUS (CONITEC). Evidências científicas: Foram realizadas análises a partir da revisão sistemática incluindo todos os medicamentos preconizados no Protocolo Clínico e Diretrizes Terapêuticas (PCDT) da esclerose múltipla na 1ª linha de tratamento, composta de betainterferonas e acetato de glatirâmer, com foco nos desfechos relacionados à frequência de recaídas (surtos). Para a comparação entre Rebif® e Avonex®, foram encontrados poucos estudos, considerados heterogêneos e com resultados imprecisos. Na comparação Betaferon® e Avonex®, o primeiro foi estatisticamente superior nos resultados. Betaferon® e Rebif® demonstraram-se semelhantes. A partir de todos os estudos identificados, foi também elaborada uma comparação indireta dessas tecnologias por meio do método MTC (Mixed Treatment Comparison). Após sucessivas simulações no modelo proposto, foram evidenciadas as seguintes probabilidades de "ser o melhor tratamento": 44,66% com o glatirâmer; 33,7% com o Betaferon®; 21,62% com o Rebif® e 0,00025% com o Avonex®. Discussão: Os resultados apresentados na comparação indireta, com o ranqueamento das tecnologias envolvidas, mostraram que a betainterferona 1a 30 mcg (6.000.000 UI), nome comercial Avonex®, apresenta-se como a pior opção de tratamento. Ou seja, o Avonex® aprsentou um perfil de desempenho de eficácia muito provavelmente inferior quando comparado ao glatirâmer e às demais betainterferonas disponíveis. Monitoramento da Incorporação: A partir do pareamento de registros nos sistemas de informação do SUS, buscaram-se evidências de efetividade do 'mundo real'. Os resultados obtidos são consistentes com os achados dos ensaios clínicos e as revisões sistemáticas conduzidas pela Colaboração Cochrane e CONITEC. Em síntese, as informações do seguimento por aproximadamente 10 anos de pacientes em uso de betainterferonas para o tratamento da esclerose múltipla no SUS demonstraram um desempenho estatisticamente inferior do Avonex®. Isso ocorreu de forma consistente no desfecho de tempo até um evento (como surto ou morte), com pior curva de sobrevida do Avonex® e no desfecho de permanência no tratamento, com menor continuidade do Avonex® em comparação às demais betainterferonas. Tais dados, obtidos em um contexto de vida real, sugerem que não só existe uma efetividade menor, discutida anteriormente com dados de ensaios clínicos em modelos de comparação indireta, como também não se pode inferir que o Avonex® esteja associado a melhores índices de adesão ao tratamento. Decisão: Restringir de uso da betainterferona intramuscular 1A 6.000.000 UI (30 mcg) no tratamento da esclerose múltipla do subtipo Remitente Recorrente, no âmbito do Sistema Único de Saúde ­ SUS, dada pela Portaria SCTIE-MS nº 27 publicada no Diário Oficial da União (D.O.U.) nº 130, de 08 de julho de 2016.

Multiple Sclerosis Relapses: Epidemiology, Outcomes and Management. A Systematic Review.

Relapses (episodic exacerbations of neurological signs or symptoms) are a defining feature of relapsing-remitting multiple sclerosis (MS), the most prevalent MS phenotype. While their diagnostic value relates predominantly to the definition of clinically definite MS, their prognostic value is determined by their relatively high associated risk of incomplete remission resulting in residual disability. The mechanisms governing a relapse incidence are unknown, but numerous modifiers of relapse risk have been described, including demographic and clinical characteristics, many of which represent opportunities for improved disease management. Also relapse phenotypes have been associated with patient and disease characteristics and an individual predisposition to certain phenotypic presentations may imply individual neuroanatomical disease patterns. While immunomodulatory therapies and corticosteroids represent the mainstay of relapse prevention and acute management, respectively, their effect has only been partial and further search for more efficient relapse therapies is warranted. Other areas of research include pathophysiology and determinants of relapse incidence, recurrence and phenotypes, including the characteristics of the relapsing and non-relapsing multiple sclerosis variants and their responsiveness to therapies.

Yoga therapy and ambulatory multiple sclerosis Assessment of gait analysis parameters, fatigue and balance.

BACKGROUND AND OBJECTIVE: Gait impairment, falls due to balance problems and fatigue are among the most important complaints in patients with multiple sclerosis (MS) and cause significant functional limitation. Use of complementary and alternative medicine (CAM) to help symptom management and to improve quality of life is growing among MS patients. Yoga is widely used as one of these CAM interventions, however, the number of studies that show the efficacy of yoga training in MS is inadequate. In this study, we aimed to evaluate the effects of a short term yoga program on fatigue, balance and gait in patients with MS. METHOD: Eight volunteer ambulatory MS patients with clinically definite relapsing remitting MS whose Expanded Disability Status Score (EDSS) is less than or equal to 6.0, and eight healthy subjects were included in the study. Patients participated in 12 weeks of a bi-weekly yoga program under supervision. At their baseline and after yoga therapy, the Fatigue Severity Scale (FSS) and Berg Balance Scale (BBS) are used to assess fatigue and balance. Three dimensional gait analysis is done using the Vicon 612 system with six cameras and two Bertec force plates, before and after therapy. RESULTS: After short term yoga therapy, statistically significant achievements were obtained in fatigue, balance, step length and walking speed. Although sagittal plane pelvis and hip angles, ankle plantar flexor moment, powers generated at the hip and ankle joints at the pre-swing were improved, the improvements were not statistically significant. CONCLUSION: Yoga therapy is a safe and beneficial intervention for improving fatigue, balance and spatiotemporal gait parameters in patients with MS. Further studies with a larger sample size and longer follow-up will be needed to evaluate the long term effects of yoga therapy.

Cost effectiveness of a pragmatic exercise intervention (EXIMS) for people with multiple sclerosis: economic evaluation of a randomised controlled trial.

BACKGROUND: Exercise is a safe, non-pharmacological adjunctive treatment for people with multiple sclerosis but cost-effective approaches to implementing exercise within health care settings are needed. OBJECTIVE: The objective of this paper is to assess the cost effectiveness of a pragmatic exercise intervention in conjunction with usual care compared to usual care only in people with mild to moderate multiple sclerosis. METHODS: A cost-utility analysis of a pragmatic randomised controlled trial over nine months of follow-up was conducted. A total of 120 people with multiple sclerosis were randomised (1:1) to the intervention or usual care. Exercising participants received 18 supervised and 18 home exercise sessions over 12 weeks. The primary outcome for the cost utility analysis was the incremental cost per quality-adjusted life year (QALY) gained, calculated using utilities measured by the EQ-5D questionnaire. RESULTS: The incremental cost per QALY of the intervention was £10,137 per QALY gained compared to usual care. The probability of being cost effective at a £20,000 per QALY threshold was 0.75, rising to 0.78 at a £30,000 per QALY threshold. CONCLUSION: The pragmatic exercise intervention is highly likely to be cost effective at current established thresholds, and there is scope for it to be tailored to particular sub-groups of patients or services to reduce its cost impact.

Time and time-frequency analysis of near-infrared signals for the assessment of ozone autohemotherapy long-term effects in multiple sclerosis.

Ozone autohemotherapy is an emerging therapeutic technique that is gaining increasing importance in treating neurological disorders. A validated and standard methodology to assess the effect of such therapy on brain metabolism and circulation is however still lacking. We used a near-infrared spectroscopy system (NIRS) to monitor the cerebral oxygenation of 9 subjects: 4 remitting-relapsing multiple sclerosis (MS) sufferers and 5 controls. Subjects were tested before, during, and after ozone autohemotherapy. We monitored the concentration changes in the level of oxygenated and deoxygenated haemoglobin, and in the level of the Cytochrome-c-oxidase (CYT-c). From the time and time-frequency analysis of the NIRS signals we extracted 128 variables, which were used to characterize the metabolic brain pattern during the therapy. We showed that by using only 7 NIRS variables out of 128 it is possible to characterize the metabolic brain pattern of the two groups of subjects. The MS subjects showed a marked increase of the CYT-c activity and concentration about 40 minutes after the end of the autohemotherapy, possibly revealing a reduction of the chronic oxidative stress level typical of MS sufferers. From a technical point of view, this preliminary study showed that NIRS could be useful to show the effects of ozone autohemotherapy at cerebral level, in a long term monitoring. The clinical result of this study is the quantitative measurement of the CYT-c level changes in MS induced by ozone autohemotherapy.

Natalizumabe 300mg para esclerose múltipla remitente recorrente em segunda linha de tratamento / Natalizumabe 300mg for recurrent remitting multiple sclerosis in second line treatment

Tecnologia: Natalizumabe (Tysabri®). Indicação: 2ª linha de tratamento para esclerose múltipla remitente recorrente (EMRR). Demandante: Biogen Idec. Contexto: A Esclerose Múltipla (EM) é uma doença autoimune, desmielinizante, crônica do sistema nervoso central, comum em adultos jovens, predominante entre mulheres, com evolução progressiva e imprevisível.A incidência mundial é de 2,5 casos novos a cada 100.000 pessoas por ano e no Brasil sua taxa de prevalência média é de aproximadamente 15 casos/100.000 habitantes, variando entre as regiões e sendo mais prevalente nas regiões sul e sudeste. Atualmente, segundo PCDT vigente (Portaria SAS/MS nº 493, de 23 de setembro de 2010), acetato de glatirâmer e betainterferona (1A ou 1B) são os fármacos de primeira escolha para o tratamento de Esclerose Múltipla Remitente Recorrente (EMRR). O uso de natalizumabe ocorre em casos refratários, tanto às betainterferonas quanto a glatirâmer, em 3ª linha de tratamento. Atualmente existem 11.650 pacientes recebendo betainterferonas, acetato de glatirâmer e natalizumabe para o tratamento de EM, entre as três linha de tratamento (DATASUS). Pergunta (PICO): O uso do natalizumabe é eficaz, seguro e custo-efetivo em pacientes com Esclerose Múltipla Remitente Recorrente quando comparado às opções disponíveis atualmente para a segunda linha de tratamento? Evidências científicas: Não há ensaios clínicos avaliando natalizumabe em monoterapia como 2ª linha de tratamento para pacientes com EMRR que alcancem os critérios de inclusão delimitados pelo PICO. Foram analisados os estudos observacionais descritos pelo demandante, que avaliaram a tecnologia na situação proposta, após falha do tratamento com acetato de glatirâmer e/ou betainterferona. Os estudos descrevem principalmente diminuição na taxa de surtos e redução do EDSS (escala expandida de estado de incapacidade) médio. Discussão: Os resultados apresentados sugerem que o benefício obtido com a tecnologia proposta é pouco evidente devido à falta de evidências científicas, e a quantidade de pacientes beneficiados demandaria maior impacto orçamentário, o que não justifica sua incorporação em 2ª linha de tratamento, conforme solicitado. Os membros da CONITEC presentes na 16ª reunião do plenário do dia 05/06/2013 deliberaram, por unanimidade, não recomendar o Natalizumabe para Esclerose Múltipla Remitente Recorrente (EMRR) em segunda linha de tratamento. Os membros solicitaram a revisão e atualização do PCDT do Ministério da Saúde vigente 9 para Esclerose Múltipla.

Treatment of relapsing-remitting multiple sclerosis: current approaches and unmet needs.

PURPOSE OF REVIEW: The aim of this review is to summarize unmet needs for patients with multiple sclerosis (MS). It is important to understand the current status of these patients and both the benefits and limitations of the most commonly used MS treatments as new medications with the potential to simplify therapy and improve outcomes may soon be available. RECENT FINDINGS: Current treatments for MS decrease the frequency of relapses and slow progressive disability. However, nearly all of these medications require frequent administration, and some patients also experience side effects. In some patients, adherence to MS treatment may be less than optimal. This may be associated with increased risk for relapses and hospitalizations and higher cost of care. SUMMARY: Healthcare providers involved in the treatment of MS must be aware of the unmet needs of their patients and intervene as needed to improve adherence and/or modify treatment regimens to optimize outcomes.

The use of multiple sclerosis condition-specific measures to inform health policy decision-making: mapping from the MSWS-12 to the EQ-5D.

BACKGROUND: Walking impairment has a major influence on the quality of life of people with multiple sclerosis (MS). The Multiple Sclerosis Walking Scale (MSWS-12) assesses the impact of MS on walking ability from the patient's perspective, but in its current form, is not amenable for use in many policy decision-making settings. OBJECTIVES: Statistical 'mapping' methods were used to convert MSWS-12 scores to EQ-5D health state values. METHODS: The relationship between the measures was estimated using cohort data from people with MS in South West England. Regression analyses were conducted, estimation errors assessed, and predictive performance of the best models tested using longitudinal data. RESULTS: Model performance was in line with that of other mapping studies, with the best-performing models being an ordinary least squares (OLS) model using MSWS-12 item scores, and an OLS model using the total MSWS-12 score and its squared term. CONCLUSIONS: A process has been described whereby data from a patient-reported outcome measure (MSWS-12) can be converted to (EQ-5D) health state values. These values may be used to consider the health-related quality of life of people with MS, to estimate quality adjusted life-years for use in effectiveness and cost-effectiveness analyses, and to inform health policy decisions.

Evidence-based guideline update: Plasmapheresis in neurologic disorders: report of the Therapeutics and Technology Assessment Subcommittee of the American Academy of Neurology.

OBJECTIVE: To reassess the role of plasmapheresis in the treatment of neurologic disorders. METHODS: We evaluated the available evidence based on a structured literature review for relevant articles from 1995 through September 2009. In addition, due to revision of the definitions of classification of evidence since the publication of the previous American Academy of Neurology assessment in 1996, the evidence cited in that manuscript was reviewed and reclassified. RESULTS AND RECOMMENDATIONS: Plasmapheresis is established as effective and should be offered in severe acute inflammatory demyelinating polyneuropathy (AIDP)/Guillain-Barré syndrome (GBS) and in the short-term management of chronic inflammatory demyelinating polyneuropathy (Class I studies, Level A). Plasmapheresis is established as ineffective and should not be offered for chronic or secondary progressive multiple sclerosis (MS) (Class I studies, Level A). Plasmapheresis is probably effective and should be considered for mild AIDP/GBS, as second-line treatment of steroid-resistant exacerbations in relapsing forms of MS, and for neuropathy associated with immunoglobulin A or immunoglobulin G gammopathy, based on at least one Class I or 2 Class II studies (Level B). Plasmapheresis is probably not effective and should not be considered for neuropathy associated with immunoglobulin M gammopathy, based on one Class I study (Level B). Plasmapheresis is possibly effective and may be considered for acute fulminant demyelinating CNS disease (Level C). There is insufficient evidence to support or refute the use of plasmapheresis for myasthenia gravis, pediatric autoimmune neuropsychiatric disorders associated with streptococcus infection, and Sydenham chorea (Class III evidence, Level U).

The long-term cost of multiple sclerosis in France and potential changes with disease-modifying interventions.

OBJECTIVE: To evaluate the long-term costs and quality of life (QoL) with and without disease-modifying treatments (DMTs) of patients with multiple sclerosis (MS). METHODS: Data on resource consumption, productivity losses, QoL (utility), and fatigue were collected from 1355 patients registered with a patient association and descriptive analyses was performed.A Markov model was developed to estimate costs and utility over 20 years using the survey data. Disease progression without DMTs was taken from an epidemiological cohort in France (EDMUS cohort, LYON). Progression under DMTs was estimated from the Stockholm MS registry. Results are presented as cost per quality-adjusted life-years (QALYs), from the societal perspective, in EUR2007, discounted at 3%. RESULTS: Mean Expanded Disability Status Scale (EDSS) was 4.4 and mean total annual costs per patient were EUR44,400, of which 47% were productivity losses and 11% informal care. Public payers cover an estimated 48% of costs. Mean utility was 0.52, and the loss compared with the normal population was estimated at 0.28. Costs and utility ranged from EUR16,000 and 0.79 at EDSS 1 to EUR76,000 and 0.11 at EDSS 8-9.Over 20 years, costs were estimated at EUR429,000 and QALYs at 8.96 for patients without DMTs and at EUR433,207 and 9.24 QALYs if all patients were starting treated with DMTs at EDSS 1-3. CONCLUSION: Although the data for this analysis come from different sources, the results indicate that the cost increase with DMTs is moderate.

Cost analysis of therapy for patients with multiple sclerosis (MS) in Poland.

Multiple sclerosis (MS) is a neurological disease of the central nervous system in which dissipated demyelination lesions develop. The currently available pharmacotherapy and rehabilitation for this disease aims to preserve the patients' physical abilities and prevent disease progression and nervous system damage. The study evaluated the direct and indirect costs associated with two different treatment regimens for multiple sclerosis diagnosed patients by comparing two groups of 60 subjects (Group A--patients receiving continuous interferon therapy (Betaferon) and steroids during relapses, and Group B--patients receiving steroid-only (Solu-Medrol, Metypred) treatment). The study was conducted over two years (2004-2005). The pharmacotherapy costs for MS patients were: PLN 4,555,360.68 (1,171,043.88euro) total for Group A and PLN 75,922.68 (19,517.40euro) per patient, and PLN 72,582.00 (18,658.61euro) total for Group B and PLN 1,209.70 (310.98euro) per patient. Total direct and indirect costs for Group A and Group B amounted to PLN 5,595,968.58 (1,438,552.33euro) and PLN 1,655,658.30 (425,619.10euro), respectively.
