Abstract
Vaccines play a crucial role in preventing infections in patients with multiple sclerosis (MS), although concerns have been raised about potential worsening of the underlying disease. To investigate this, we conducted a prospective, multicentre, non-randomized observational study assessing changes in disease activity, safety, and clinical tolerability of vaccination in 222 MS patients on disease-modifying drugs. The majority of patients were female (76.6%) and 89.6% had relapsing-remitting MS. The vaccines administered were primarily seasonal influenza (56.3%) or tetanus-based vaccines (33.8%). Disease activity, as measured by annualized relapse rate, decreased significantly from 0.64 the year prior to vaccination to 0.38 in the following year. Moreover, the extended disability status scale remained stable within six months after vaccination in comparison to pre-vaccination values. Side effects were reported in 19.2% of vaccinated subjects, most commonly local side effects (65.2%) or flu-like symptoms (34.8%). Our findings suggest that standard non-live vaccines are safe and well-tolerated in MS patients and do not negatively impact disease activity.

Abstract
A patients Because of the past 3 decades’ extensive research, several disease modifying therapies became available, thus a paradigm change is multiple sclerosis care was necessary. In 2018 a therapeutic guideline was created recommending that treatment of persons with multiple sclerosis should take place in specified care units where the entire spectrum of disease modifying therapies is available, patient monitoring is ensured, and therapy side effects are detected and treated promptly. In 2019 multiple sclerosis care unit criteria were developed, emphasizing personnel and instrumental requirements to provide most professional care. However, no survey was conducted assessing the real-world adaptation of these criteria. Objective To assess whether Hungarian care units fulfil international criteria. Methods A self-report questionnaire was assembled based on international guidelines and sent to Hungarian care units focusing on 3 main aspects: personnel and instrumental background, disease-modifying therapy use, number of people living with multiple sclerosis receiving care in care units. Data on number of persons with multiple sclerosis were compared to Hungarian prevalence estimates. Descriptive statistics were used to analyse data. Results Out of 27 respondent care units, 3 fulfilled minimum requirements and 7 fulfilled minimum and recommended requirements. The least prevalent neighbouring specialties were spasticity and pain specialist, and neuro-ophthalmologist and oto-neurologist. Only 15 centres used all available disease modifying therapies. A total number of 7213 people with multiple sclerosis received care in 27 respondent centres. Compared to prevalence estimates, 2500 persons with multiple sclerosis did not receive multiple sclerosis specific care in Hungary. Conclusion Less than half of Hungarian care units provided sufficient care for people living with multiple sclerosis. Care units employing fewer neighbouring specialties, might have difficulties diagnosing and providing appropriate care for persons with multiple sclerosis, especially for people with progressive disease course, contributing to the reported low number of persons living with multiple sclerosis.

Abstract
Background People with Multiple Sclerosis (PwMS) suffer from an increased risk of
unemployment during the course of the disease. In recent years progress has
been made in increasing the time until patients have to leave the workforce
permanently. Such a retirement is often associated with MS but the driving
factors including disability progression, support measures at the workplace,
and societal aspects are not yet fully understood. Methods We consolidated data from four European MS databases from Germany, Poland,
Sweden, and the United Kingdom, which were able to provide data on working
status, disability progression and quality of life in accordance with the
data harmonization framework of the EUReMS (European Registry in Multiple
Sclerosis) project. Results Factors strongly associated with unemployment are disability progression, low
quality of life and being close to the statutory retirement age. Overall,
highest employment rate (77%) and lowest effects of gender and disease
duration were found in Sweden. Conclusions We found remarkable differences between the European registers and the
countries studied, which may indicate inequalities at European level.
Furthermore, our findings suggest that it is feasible and useful to combine
data from different MS registers in Europe, albeit the data structures are
heterogeneous.

Chances and Challenges of Registry-Based Pharmacovigilance in Multiple Sclerosis: Lessons Learnt from the Implementation of the Multicenter REGIMS Registry. Drug Saf 2020; 44:7-15.

Abstract
The long-term and potential rare side effects of new immunomodulating drugs for the treatment of multiple sclerosis (MS) are often not well known. Spontaneous case report systems of adverse drug effects are a valuable source in pharmacovigilance, but have several limitations. Primary data collections within registries allow a comprehensive analysis of potential side effects, but face several challenges. This article will outline the chances and challenges of registry-based adverse event reporting, using the example of the German immunotherapeutic registry REGIMS. REGIMS is an observational, clinical multicenter registry that aims to assess the incidence, type, and consequences of side effects of MS immunotherapies. Patients treated with an approved MS medication are recruited by their physicians during routine visits in hospitals, outpatient clinics, and MS-specialized practices. REGIMS incorporates an electronic physician-based documentation in each center and a paper-based patient documentation, both at baseline and regular follow-up visits. By the end of 2019, 43 REGIMS centers were actively recruiting patients and performing follow-up documentations. The majority of the first 1000 REGIMS patients were female (69.3%), had relapse-remitting MS (89.8%), and were treated with a second-line therapy. During the implementation of REGIMS, several logistic and procedural challenges had to be overcome, which are outlined in this paper. Pharmacovigilance registries such as REGIMS provide high-quality primary data from a specific patient population in a real-world care setting and enable pharmacovigilance research that cannot be carried out using secondary data. Despite the logistic and procedural challenges in establishing a multicenter pharmacovigilance registry in Germany, the advantages outweigh the drawbacks.

Abstract
Daclizumab was approved by the FDA and the EMA in 2016 for the treatment of relapsing forms of multiple sclerosis (MS). Cases of severe inflammatory brain disease with fatal outcome led to the withdrawal of approval in Europe and the US on March 2, 2018. Approximately 8,000 patients worldwide received daclizumab, but little is known about the further therapy management of these patients after the withdrawal of daclizumab. The aim of this study is to further analyze therapy management in MS patients after safety warnings and market withdrawal. Data from two registries in Germany, the German MS Registry (GMSR) and REGIMS, were used for this analysis. In total, 267 patients were included in this study. For almost 25% of patients (in the GMSR) daclizumab was the initial treatment. Most common pre-treatments were fingolimod, dimethyl fumarate, and natalizumab; various injectables summed up to 25.9%. The most common follow-up therapies were ocrelizumab and fingolimod. In most patients, follow-up therapies were administered shortly after discontinuation of daclizumab. The wash-out time for subsequent therapies varied between 1.2 and 4.0 months. Warnings and decisions by authorities led to a rapid decline and termination of therapies in both cohorts, indicating that such warnings have an immediate impact on the treatment landscape. Therapies that were started within a short time after the discontinuation of daclizumab were subsequently replaced by other therapies and may be considered as bridging therapies.

Abstract
BACKGROUND Multiple Sclerosis (MS) is a chronic inflammatory, immune mediated disease of the central nervous system, with Relapsing Remitting MS (RRMS) being the most common type. Within the last years, the status of high disease activity (HDA) has become increasingly important for clinical decisions. Nevertheless, little is known about the incidence, the characteristics, and the current treatment of patients with RRMS and HDA in Germany. Therefore, this study aims to estimate the incidence of HDA in a German RRMS patient population, to characterize this population and to describe current drug treatment routines and further healthcare utilization of these patients. METHODS A claims data analyses has been conducted, using a sample of the InGef Research Database that comprises data of approximately four million insured persons from around 70 German statutory health insurances (SHI). The study was conducted in a retrospective cohort design, including the years 2012-2016. Identification of RRMS population based on ICD-10 code (ICD-10-GM: G35.1). For identification of HDA, criteria from other studies as well as expert opinions have been used. Information on incidence, characteristics and current treatment of patients with RRMS and HDA was considered. RESULTS The overall HDA incidence within the RRMS population was 8.5% for 2016. It was highest for the age group of 0-19 years (29.4% women, 33.3% men) and lowest for the age group of ≥ 50 years (4.3% women, 5.6% men). Mean age of patients with RRMS and incident HDA was 38.4 years (SD: 11.8) and women accounted for 67.8%. Analyses of drug utilization showed that 82.4% received at least one disease-modifying drug (DMD) in 2016. A percentage of 49.8% of patients received drugs for relapse therapy. A share of 55% of RRMS patients with HDA had at least one hospitalization with a mean length of stay of 13.9 days (SD: 18.3 days) in 2016. The average number of outpatient physician contacts was 28.1 (SD: 14.0). CONCLUSIONS This study based on representative Germany-wide claims data from the SHI showed a high incidence of HDA especially within the young RRMS population. Future research should consider HDA as an important criterion for the quality of care for MS patients.

Ketogenic diet and fasting diet as Nutritional Approaches in Multiple Sclerosis (NAMS): protocol of a randomized controlled study. Trials 2020; 21:3. [PMID: 31898518 PMCID: PMC6941322 DOI: 10.1186/s13063-019-3928-9] [Citation(s) in RCA: 42] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2019] [Accepted: 11/22/2019] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Multiple sclerosis (MS) is the most common inflammatory disease of the central nervous system in young adults that may lead to progressive disability. Since pharmacological treatments may have substantial side effects, there is a need for complementary treatment options such as specific dietary approaches. Ketone bodies that are produced during fasting diets (FDs) and ketogenic diets (KDs) are an alternative and presumably more efficient energy source for the brain. Studies on mice with experimental autoimmune encephalomyelitis showed beneficial effects of KDs and FDs on disease progression, disability, cognition and inflammatory markers. However, clinical evidence on these diets is scarce. In the clinical study protocol presented here, we investigate whether a KD and a FD are superior to a standard diet (SD) in terms of therapeutic effects and disease progression. METHODS This study is a single-center, randomized, controlled, parallel-group study. One hundred and eleven patients with relapsing-remitting MS with current disease activity and stable immunomodulatory therapy or no disease-modifying therapy will be randomized to one of three 18-month dietary interventions: a KD with a restricted carbohydrate intake of 20-40 g/day; a FD with a 7-day fast every 6 months and 14-h daily intermittent fasting in between; and a fat-modified SD as recommended by the German Nutrition Society. The primary outcome measure is the number of new T2-weighted MRI lesions after 18 months. Secondary endpoints are safety, changes in relapse rate, disability progression, fatigue, depression, cognition, quality of life, changes of gut microbiome as well as markers of inflammation, oxidative stress and autophagy. Safety and feasibility will also be assessed. DISCUSSION Preclinical data suggest that a KD and a FD may modulate immunity, reduce disease severity and promote remyelination in the mouse model of MS. However, clinical evidence is lacking. This study is the first clinical study investigating the effects of a KD and a FD on disease progression of MS.

Abstract
BACKGROUND Real-world evidence (RWE) expands the data obtained in randomized clinical trials (RCTs), which are based on both homogeneous selected patient groups and limited study durations, to long-term experiences in clinical routine. In particular, chronic diseases such as multiple sclerosis (MS) with both heterogeneous pathologies and a growing number of therapeutic options require a careful RWE-based assessment of long-term efficacy and safety parameters. OBJECTIVE This review presents RWE data sources applied in MS research and discusses potential quality standards. MATERIAL AND METHODS This article is based on the results of an expert meeting of the authors held in October 2015 and a selective literature search. RESULTS The RWE data sources include the reporting system of drug safety monitoring, non-interventional studies, MS-specific registries, administrative health databases, and electronic medical records. These data sources have different objectives and are subject to specific limitations with respect to the disease and therapy-relevant analytical options. The combination of different sources into an integrative approach might improve the validity of RWE in MS research; however, this objective requires the standardization of data collection and processing as well as the definition of uniform and transnational quality standards. CONCLUSION There is still a need for high-quality, comprehensive, and valid RWE data as these data cover additional aspects of patient care and expand the data available by complementary information. Further development of an integrative RWE approach requires cooperation at various levels with the aim of the best possible standardization and harmonization of clinical MS data.

Abstract
Multiple sclerosis (MS) is the most common immune-mediated inflammatory disease of the central nervous system (CNS). Early diagnosis and treatment is important to prevent progression of disability in the course of the chronic disease. Therefore, correct and fast identification of early symptoms is vital. Headache is generally not recognized as an early symptom of MS, although numerous studies could show a high prevalence of headache in MS patients. The most common misdiagnosis is migraine. The aim of this study is to investigate the prevalence as well as the phenomenology of headache in MS especially with regard to the progression of the disease. In a prospective, multicenter study, we unbiasedly recruited 150 patients with manifest MS based on the criteria of McDonald. 50 patients at the timepoint of initial diagnosis and 100 of them with a long-term course of the disease were included. Based on a semi-structured interview, we evaluated the occurrence of headache over the last 4 weeks as well as case history, clinical-neurological investigation and questionnaires about depression, fatigue, and quality of life. Prevalence of headache in all patients was 67%. Patients at the timepoint of symptom manifestation of MS showed the highest prevalence of headache that was ever been recorded of 78%. In general, patients with headache were younger, had a shorter duration of the disease, and were less physically affected. We noticed frequent occurrence of migraine and migraine-like headache. In the course of the disease, patients without disease-modifying drug (DMD) complained more frequently headaches than patients with any kind of therapy. Headache is an important early symptom of MS. This could be shown especially among 78% of patients with clinically isolated syndrome (CIS). Therefore, young people with frequent headache should undergo MRI of the head and in the case of abnormal findings a consecutive detailed differential diagnosis. This could reduce the latency until final diagnosis of MS, which is in general much too long. That way these patients could get the earliest possible treatment, which is important to stop the progression of the disease.

Abstract
Introduction: Worldwide, incidence and prevalence of multiple sclerosis (MS) have increased over the last decades. We present a systematic epidemiological study with recent prevalence and incidence rates of MS in Bavaria. Methods: Incidence and prevalence of MS stratified by gender, age groups and region were analyzed by data records from 2006 to 2015 of more than 10 million people insured by the Bavarian Association of Statutory Health Insurance Physicians. Official statistics of the German Federal Ministry of Health provided the size of the general population. Future prevalence was estimated with a predictive model. Results: From 2006 to 2015 prevalence of MS in Bavaria increased from 171 per 100,000 to 277 per 100,000, while incidence rates remained relatively stable (range 16-18 per 100,000 inhabitants with a female to male ratio between 2.4:1 and 2:1). Incidence and prevalence were higher in urban than urbanized and rural areas. The prevalence is expected to increase to 374 per 100,000 in 2040 with the highest prevalence rates between 50 and 65 years. Conclusion: The prevalence of MS in Bavaria is among the highest worldwide and will further rise over the next two decades. This demonstrates a need to strengthen healthcare provision systems due to the increasing numbers of particularly older patients with MS in the future.

Abstract
Multiple Sclerosis (MS) is the most common, primary neurogenic cause of disability among young adults. We investigated demographic and clinical factors associated with unemployment on the example of 150 MS patients receiving immunomodulatory treatment in Poland. This study was based on clinical evaluation and collection of self-reported questionnaires, with an attention to self-motivation, severe fatigue and moderate disability. Patients who were unemployed (40% of all patients) had a mean disease duration of almost 5 years. Older (p<0.001), less educated (p = 0.007) and more severely disabled patients (p<0,001) were most likely to be unemployed. Moderate disability (OR = 11.089 95% CI: 4.11-34.201, p<0,001), severe fatigue (OR = 2.625 95% CI: 1.02-6.901, p = 0,046) and lower level of self-motivation (KNS) (OR = 0.947, 95% CI: 0.896-0.006, p = 0.042) were independently associated with unemployment.

Abstract
Objectives Multiple sclerosis (MS) is the most frequent immune-mediated inflammation of the central nervous system that can lead to early disability. Headaches have not been considered as MS-related symptoms initially, whereas higher prevalence rates were reported since 2000. Postmortem histological analyses of MS patients' brains revealed lymphoid follicle-like structures in the cerebral meninges which suggest a possible pathophysiological explanation for the high headache prevalence in MS. The aim of this study was to evaluate headache characteristics during the first clinical event of MS. Methods In a prospective, multicenter study, 50 patients with the diagnosis of CIS or MS were recruited. All participants were screened for the presence of headache within the last 4 weeks with help of the Rostock Headache Questionnaire (Rokoko). Results Thirty-nine of fifty questioned patients (78%) reported headaches within the last 4 weeks. Most patients suffered from throbbing and pulsating headaches (25, 50%), 15 (30%) reported stabbing, 14 (28%) dull and constrictive headaches. Conclusions Headaches were prevalent in 78% of patients in our population with newly diagnosed CIS and MS. It is among the highest prevalence rates reported so far in patients with CIS or MS. Thus, headache, especially of a migraneous subtype, is a frequent symptom within the scope of the first manifestation of multiple sclerosis. If it were possible to define a MS-typical headache, patients with these headaches and with typical MRI results would be classified as CIS or early MS instead of radiologically isolated syndrome and treated accordingly with an immunomodulatory therapy.

Abstract
Background Multiple sclerosis (MS) patients often suffer from gait impairment and fampridine is indicated to medically improve walking ability in this population. Patient characteristics, healthcare resource use, and costs of MS patients on fampridine treatment for 12 months in Germany were analyzed. Methods A retrospective claims database analysis was conducted including MS patients who initiated fampridine treatment (index date) between July 2011 and December 2013. Continuous insurance enrollment during 12 months pre- and post-index date was required, as was at least 1 additional fampridine prescription in the fourth quarter after the index date. Patient characteristics were evaluated and pre- vs post-index MS-related healthcare utilization and costs were compared. Results A total of 562 patients were included in this study. The mean (standard deviation [SD]) age was 50.5 (9.8) years and 63% were female. In the treatment period, almost every patient had at least 1 MS-related outpatient visit, 24% were hospitalized due to MS, and 79% utilized MS-specific physical therapy in addition to the fampridine treatment. Total MS-related healthcare costs were significantly higher in the fampridine treatment period than in the period prior to fampridine initiation (€17,392 vs €10,960, P < 0.001). While this difference was driven primarily by prescription costs, MS-related inpatient costs were lower during fampridine treatment (€1,333 vs €1,565, P < 0.001). Conclusions Physical therapy is mainly used concomitant to fampridine treatment. While healthcare costs were higher during fampridine treatment compared to the pre-treatment period, inpatient costs were lower. Further research is necessary to better understand the fampridine influence.

Abstract
Background Multiple sclerosis (MS), a progressive neurodegenerative disease, greatly impacts the quality of life and economic status of people affected by this disease. In Germany, the total annual cost of MS is estimated at €40,000 per person with MS. Natalizumab has shown to slow MS disease progression, reduce relapses, and improve the quality of life of people with MS. Objective To evaluate MS-related and all-cause health care resource utilization and costs among German MS patients during the 12 months before and after initiation of natalizumab in a real-world setting. Methods The current analysis was conducted using the Health Risk Institute research database. Identified patients were aged ≥18 years with ≥1 diagnosis of MS and had initiated natalizumab therapy (index), with 12-month pre– and post–index-period data. Patients were stratified by prior disease-modifying therapy (DMT) usage or no DMT usage in the pre-index period. Outcome measures included corticosteroid use and number of sick/disability days, inpatient stays, and outpatient visits. Health care costs were calculated separately for pre- and post-index periods on a per-patient basis and adjusted for inflation. Results In a final sample of 193 natalizumab-treated patients, per-patient MS-related corticosteroid use was reduced by 62.3%, MS-related sick days by 27.6%, and inpatient costs by 78.3% from the pre- to post-index period. Furthermore, the proportion of patients with MS-related hospitalizations decreased from 49.7% to 14.0% (P<0.001); this reduction was seen for patients with and without prior DMT use. Conclusions In a real-world setting in Germany, initiation of natalizumab treatment in people with MS significantly reduced MS-related hospitalizations, corticosteroid use, sick days, and associated costs.

Abstract
BACKGROUND Multiple sclerosis (MS) is a complex autoimmune disease with a heterogeneous presentation and diverse disease course. Recent studies indicate a rising prevalence of MS in the Middle East. OBJECTIVE To characterize the demographics and disease features of Egyptian patients attending four tertiary referral MS centers in Cairo. MATERIALS AND METHODS This was a retrospective, observational study on 1,581 patients between 2001 and 2015. Medical records were reviewed and data were identified and extracted in a standardized electronic registry. RESULTS The mean age of disease onset was 26.6±7.8 years, with the majority being female (2.11:1). Relapsing-remitting MS was the most common type (75.1%). The main presenting symptom was motor weakness (43.9%), which was also the most frequent symptom during the disease course. Family history of MS was found in 2.28%. Higher initial Expanded Disability Status Scale score, black holes, and infratentorial lesions on initial magnetic resonance imaging were independent factors for disease progression by univariate analysis (OR 3.87 [95% CI 1.84-6.51], 4.14 [95% CI 3.08-5.58], 4.07 [95% CI 3.21-4.99], respectively); however, in multivariate analysis, only infratentorial lesions were an independent risk for disease progression (OR 6, 95% CI 2.99-12.02; P=0.0005). CONCLUSION The results from this registry - the largest for MS in the Arab region to date - are comparable to other registries with slight differences.

Abstract
BACKGROUND Nationwide population-based information on the prevalence of multiple sclerosis (MS) in Germany has so far not been available. In this study the prevalence of MS was determined with the help of the claims data of the health insurance funds underlying the morbidity-based risk adjustment scheme (M-RSA). MATERIAL AND METHODS Health insurance funds reported inpatient and outpatient diagnoses, outpatient prescriptions, costs and enrolment data for all persons insured in the German statutory health insurance (SHI). The data reported for 2010 form the basis of this study which collated data on the 12-month prevalence, prevalence related to age and gender, drug therapy, regional distribution pattern, combinations of diagnoses and hospitalization. RESULTS Nearly 200,000 people insured in the SHI have been diagnosed with MS. Hence, the prevalence seems to be considerably higher than was previously assumed. In addition, a slight west-east gradient was apparent. On average 49 % of all MS patients (with a slight east-west gradient) received MS-specific inpatient drug therapy. Insured patients living in the east received on average 30 daily doses per year less than patients living in the western part. CONCLUSION For the first time MS prevalence has been determined nationwide for Germany with the help of SHI data. It appears that previously applied methods have underestimated the prevalence. The regional differences found with respect to prevalence and drug therapy need further clarification. The data underlying the M-RSA do not allow more causal research.

Abstract
Introduction Reduced working capability is one of the most devastating consequences of multiple sclerosis (MS). We aimed to study working capability and related variables in Swiss MS patients. Materials and Methods A cross-sectional analysis of employment status and risk factors for reduced working capability among MS patients treated at our outpatient clinic. A questionnaire was mailed to 644 MS patients and returned by 69.7%. 405 patients (66% female, mean age 44.2 years (SD±10.2), median EDSS 3.0 (SD±1.8)) were eligible for subsequent analysis. Results After a mean disease duration of 12.3 years (SD±8.25), full or part time employment was declared by 26.7% and 25.7%, respectively. Incapacity to work was reported by 27.1%. A total of 52.8% specified MS as the cause for altered working capability, whereas 20.5% cited reasons unrelated to the disorder. Even with minimal disability (EDSS<3) a significant proportion of patients (24%) reported reduced working capability. Among the MS-specific restricting factors were fatigue (47.6%), sensorimotor deficits (31.1%), impaired vision (3.3%) and pain (2.8%). Conclusion MS continues to takes its toll on the professional life of the patients early in the course. While complete incapacity becomes relevant with moderate to severe disability, many patients scale down to part-time even with minimal impairment.

Abstract
There is increasing evidence that physical exercise leads to numerous positive effects in PwMS. However, long-term effects of exercise may only be achievable if training is implemented in daily routine. Enabling patients to exercise regularly, we developed a patient education program focused on evidence-based information of training. PwMS were educated in neurophysiological effects of physical exercise, exercise-induced benefits for PwMS, and risk factors (e.g., weather). Fifteen PwMS were analyzed before (T 0) and after (T 1) a 12-week patient education. Afterwards, participants performed their exercises autonomously for 32 weeks and were tested in sustainability tests (T 2). Guided interviews were carried out, additionally. Significant improvements from T 0 to T 1 were found in 6MWT, gait velocity, TUG, fatigue, and quality of life. Significant results of TUG and gait velocity from T 1 to T 2 demonstrated that participants kept few effects after the 32-week training phase. Qualitative analyses showed improved self-confidence and identified training strategies and barriers. This pilot study provides evidence that PwMS are able to acquire good knowledge about physical exercise and apply this knowledge successfully in training management. One might conclude that this exercise-based patient education seems to be a feasible option to maintain or improve patients' integral constitution concerning physical and mental health.

Abstract
Multiple sclerosis (MS) is a chronic disease of central nervous system. The multiple sclerosis information system (MSIS), such as other information system (IS), depends on identification, collection and processing of data for producing useful information. Lack of the integrated IS for collecting standard data causes undesirable effects on exchanging, comparing, and managing. The aim of this study was to recognize the role of the IS in the MS management and determine the advantages and barriers in implementing of the MSIS. The present study was a nonsystematized review that was done in order to recognize the role of the IS in the MS management. In this study, electronic scientific resources such as scientific magazines and books and published topics at conferences were used. We used key words (IS, chronic disease management, and multiple sclerosis), their combination or their synonyms in title, key words, abstracts, and text of English articles and published reports from 1980 until 2013, and by using search engines such as Google, Google Scholar and scientific databases and electronic issues such as iPubMed, sufficiently important difference, Scopus, Medlib, and Magiran for gathering information. More than 200 articles and reports were collected and assessed and 139 of them. Findings showed that the MSIS can reduce of disease expenses through continuously collecting correct, accurate, sufficient, and timely patients and disease nature information; recoding; editing; processing; exchanging, and distributing among different health care centers. Although the MSIS has many advantages; but, we cannot ignore cultural, economic, technical, organizational, and managerial barriers. Therefore, it is necessary to do studies for preventing, reducing, and controlling them. One of the ways is to recognize the advantages of the MSIS and usage information technology in optimizing disease management.

Abstract
Background Healthcare-utilization data for multiple sclerosis (MS) are scarce in Germany. The Purpose of the study was to analyse administrative prevalence of MS, medication use and type of specialists involved in MS treatment in the outpatient setting in Bavaria. Methods Pseudonymized claims data from Bavarian Statutory Health Insurance (SHI)-accredited physicians were used. Administrative prevalence of MS was defined as having ≥1 MS diagnosis (International Classification of Diseases, 10th edition, code G35) documented by a neurologist or psychiatrist, or ≥1 prescription for disease-modifying drugs (DMDs)). The administrative prevalence calculated for Bavaria was projected to Germany. DMD prescription and involvement of different specialities in health care service for MS patients was analysed. Results Administrative prevalence of MS in Bavaria increased from 0.123% to 0.175% of insured persons between 2005 and 2009; when projected, this yielded ~102,000–143,000 patients with MS in the German population. The percentage of patients receiving ≥1 DMD prescription increased from 45.5% to 50.5%. Patients with MS were mainly treated by neurologists in the ambulatory care setting. Conclusions These results provide important information on the administrative prevalence of MS in Bavaria and on healthcare provision for patients, which is relevant for resource planning in the healthcare sector.

Abstract
BACKGROUND For persons covered by statutory health insurance (SHI) an increase in the number of defined daily doses (DDD) for pharmaceuticals to treat multiple sclerosis (MS) is known but so far there has been no comparable survey for private health insurance (PHI). Moreover, there are gaps in knowledge of the reasons for the increase and concerning the number of the MS patients in Germany. MATERIAL AND METHODS The study is based on pharmaceutical data of the PHI in Germany. The projection takes into account the different prevalence and the different male/female relationship in SHI and PHI in an extrapolation to the total population. RESULTS From 2006 to 2010 the number of DDDs of MS pharmaceuticals increased by approximately 91.6 % (SHI 39.9 %) per insured person. The increase in the PHI is mainly based for on an increase in the number of MS patients. The total number of MS patients in Germany was estimated to be approximately 146,000 whereby some 12,700 MS patients (8.7 %) were insured in PHI. CONCLUSION There is a need for research into the reasons for the increase in MS patients. The disproportional increase in the PHI compared to SHI could be a result of the increase of insured persons and an increased inclusion of persons with a higher risk of the disease.

Abstract
BACKGROUND The incidence of therapy-related acute leukaemia (TRAL) in mitoxantrone treatment in multiple sclerosis (MS) is controversially discussed. METHODS AND RESULTS In a retrospective meta-analysis from six centres, we observed six cases of acute myeloid leukaemia (AML) (incidence 0.41% for patients with mean follow up after end of treatment of 3.6 years, n = 1.156; incidence 0.25% for all patients, n = 2.261). Potential influencing factors such as myelotoxic or glucocorticosteroid pretreatment/cotreatment were present in all but one case of TRAL. Between 1990 and 2010, 11 cases of TRAL were reported to the Drug Commission of the German Medical Association (estimated risk of 0.09-0.13%). CONCLUSIONS Regional differences in reported TRAL incidence may point to confounding cofactors such as administration protocols and cotreatments.

Abstract
This review gives an overview of national registries that are currently in use for patients with multiple sclerosis (MS). The large-scale registries described herein include the Danish MS Registry, the Norwegian MS Registry, the Swedish MS Registry, the Italian MS Database Network, the North-American NARCOMS Registry, and the German MS Registry. These MS registries are extremely helpful for studying disease characteristics in large populations and monitoring the long-term outcome of disease-modifying therapies. Furthermore, an almost complete ascertainment of cases provides information on the provision of treatments, services and supplies within a given area that may be used to compare different levels of health care within and between these regions. In the long-term, MS registries monitor the health care situation of MS patients over time including the implementation of guidelines relating to care and treatment, measure the improvements that have taken place, and reveal shortages and/or misalignment in health care services. The information gathered herein is not only useful for the long-term follow-up of the individual patient, but also for society as a whole by increasing understanding of and knowledge about MS and allowing national authorities and relevant parties to make informed and relevant decisions about MS.

Abstract
Despite novel immunoactive agents, immunosuppressants still play a considerable role in the treatment of MS, especially in rapidly progressive cases. Given the limited tolerability and potentially severe side effects of most immunosuppressive drugs, identification of patients with a favorable benefit-risk profile is essential. A narrow therapeutic index, with sometimes high interindividual variability in terms of response and side effects may partially be explained by genetic factors affecting different metabolic pathways. Here, we will review practical aspects in the clinical use of immunosuppressants in MS and discuss approaches to individualized treatment schemes, including novel pharmacogenetic strategies.
