Nurse-led immunotreatment DEcision Coaching In people with Multiple Sclerosis (DECIMS) - A cluster- randomised controlled trial and mixed methods process evaluation.

OBJECTIVE: To evaluate a nurse-led decision coaching programme aiming to redistribute health professionals' tasks to support immunotherapy decision-making in people with multiple sclerosis (MS). METHODS: Cluster-randomised controlled trial with an accompanying mixed methods process evaluation (2014 - 2018). We planned to recruit 300 people with clinically isolated syndrome or relapsing-remitting MS facing immunotherapy decisions in 15 clusters across Germany. Participants in the intervention clusters received up to three decision coaching sessions by a trained nurse and access to an evidence-based online information platform. In the control clusters, participants also had access to the information platform. The primary outcome was informed choice after six months, defined as good risk knowledge and congruent attitude and uptake. RESULTS: Twelve nurses from eight clusters participated in the decision coaching training. Due to insufficient recruitment, the randomised controlled trial was terminated prematurely with 125 participants (n = 42 intervention clusters, n = 83 control clusters). We found a non-significant difference between groups for informed choice favouring decision coaching: odds ratio 1.64 (95% CI 0.49-5.53). CONCLUSIONS: Results indicate that decision coaching might facilitate informed decision-making in MS compared to providing patient information alone. PRACTICE IMPLICATIONS: Barriers have to be overcome to achieve structural change and successful implementation.

"Activity Matters was great - I now realize: if I move, I'm fitter.": development and process evaluation of a web-based program for persons with multiple sclerosis.

PURPOSE: Research shows that persons with mild to moderate multiple sclerosis are less physically active than healthy controls even though they would benefit from it. This study focusses on the feasibility testing and process evaluation of the pilot study of Activity Matters, a twelve-week web-based program, from Ireland, to increase physical activity in this population. MATERIALS AND METHODS: The intervention was adapted to local circumstances in Hamburg, Germany and consists of eleven modules incorporating behavior change techniques. After feasibility had been confirmed, 43 persons with multiple sclerosis participated in a pilot study with a pre-post, single-group intervention design. Qualitative data was collected with questionnaires and semi structured interviews. Physical activity level and stage of change was measured quantitatively. RESULTS: Participants had a mean age of 49.5 years (SD 9.29) and an average Patient Determined Disease Step Score of 2.2 (SD 1.47). Thirty-six participants answered the follow-up questionnaire. On average 9.8 modules were processed within 13 weeks. Each tool for behavior change was perceived as helpful except the chat group. Physical activity levels increased significantly from pre- to post intervention (p-value 0.042, Cohen's d = 0.35). CONCLUSIONS: The results indicate that Activity Matters is feasible and satisfactory and may change activity levels.

Activity Matters provides a twelve-week web-based self-management program to increase PA which is feasible and well accepted by middle aged, mild to moderately impaired persons with MS.Persons with MS in this online program were pleased with the overall content and the self-regulation strategies, however some were seeking for more personal contact and interaction with the study team and other participants.Stronger individualisation of web-based programs to the diverse needs of participants remains a challenge that has to be solved in the future.

German guideline for diagnosis and treatment of multiple sclerosis - a survey focusing neurologists in daily practise.

We performed a web-based survey among German-speaking neurologists to evaluate the acceptance of the 2021 German guideline in the diagnosis and treatment of multiple sclerosis. Based on 327 replies in total, the current survey largely reproduced the findings of an earlier, smaller survey on the prefinal consultation version of the guideline and confirmed high acceptance rates. Half of the participants were practising neurologists. Neurologists from MS centers with more than 500 patients per year (n=26) were more critical of the guideline. They reiterated some of the criticisms of the previous feedback, and, in particular, felt that safety aspects are overemphasized in the guideline, thereby superseding early aggressive therapy.

The Sylvia Lawry Centre for Multiple Sclerosis Research (SLCMSR)--Critical review facing the 20 anniversary.

The SLCMSR was formed as an international Multiple Sclerosis Trials, Research and Resource Center to identify clinical MRI and other predictors of the course of multiple sclerosis (MS) based on a large database of natural history and clinical trial data. Using an elaborate validation concept several key findings were published, challenging established outcome parameters and their assessment in MS such as disability ratings with Expanded Disability Status Scale (EDSS), relapses and MRI endpoints. Sustained increase of EDSS appeared to be an invalid outcome for 2-3 year clinical trials at least in patients with relapsing-remitting MS. The number of gadolinium-enhancing lesions and T2-lesion load on MRI were shown not to have a meaningful additional predictive value for the disease course. These issues risen some 15 years ago had triggered controversial discussions which have also been noticed by regulatory authorities and they all have not been resolved. In addition the SLCMSR contributed to the development of new outcomes such as real-world walking speed as an attractive, ecologically valid tool based on a wearable device. A so-called evidence-based-decision-support tool was constructed to provide individual prognostic estimates based on a matching algorithm to a given database. This paper condensates the findings of 20 years of critical MS research.

Development and evaluation of evidence-based patient information handbooks about multiple sclerosis immunotherapies.

BACKGROUND: Multiple sclerosis treatment options are increasing. Evidence-based patient information (EBPI) are therefore crucial to enable patient involvement in decision making. Based on earlier work on decision support, patient information handbooks on 8 MS immunotherapies were developed, piloted and evaluated with support from the German Clinical Competence Network MS and the German MS Society. METHODS: Handbooks were structured according to EBPI concepts. Drafts were commented by patient representatives and neurologists with an MS expertise. Executive boards of the German MS Society and the Competence Network as well as pharmaceutical companies' feedback was included. Handbooks were distributed among MS neurologists by the German MS Society. Evaluation followed applying a mixed methods approach with interviews, focus groups and surveys. One survey addressed persons with MS (pwMS) based on a questionnaire included in each handbook. Neurologists who received printed patient handbooks were invited to give feedback in a second survey. RESULTS: Eight handbooks were developed providing absolute and relative risk information in numbers and figures as well as monitoring needs and drug fact boxes. Despite the high amount of information and the display of low absolute risk reduction rates of treatments, handbooks were overall appreciated by pwMS (n=107) and mostly also by physicians (n=24). For more than 70% of the pwMS the information was new, understandable and supportive for decision making. But patients felt uncomfortable with relative risk information. However, response rates in the evaluation were low, exposing the challenges when implementing EBPI into clinical care. Therefore, conclusions must be considered preliminary. CONCLUSION: EBPI on immunotherapies for MS seem feasible and are appreciated by patients and treating neurologists but more implementation research is needed.

Implementation study of the 2021 German guideline for diagnosis and treatment of multiple sclerosis.

BACKGROUND: In May 2021, a new guideline on the diagnosis and treatment of multiple sclerosis and related disorders was released in Germany. Since the success of a guideline depends on how it integrates into everyday clinical practice, the German Society for Neurology (DGN) has launched a multimethod implementation project. Here we report on the results based on the consultation version of the guideline. METHODS: We used qualitative and quantitative data analyses to capture the nature and extent of barriers and facilitating factors to the implementation. We centered on the guideline's chapter A on diagnosis, relapse therapy, and immunotherapy of multiple sclerosis. We performed nine online focus group discussions and a web-based survey and analyzed emails and letters with comments from stakeholders and independent parties that were sent spontaneously or by invitation. RESULTS: 94 neurologists answered the survey, and ≥70% agreed with the recommendations of the guideline on each major content topic. Barriers to implementation were detected in group discussions and written input. The most controversial issues of the guideline were "early treatment", "criteria for starting or switching therapy", "stepwise escalation versus early aggressive treatment", "classification of drugs into three categories of efficacy" and the scenarios on "treatment cessation". Some appreciated the highly structured recommendations, but others felt that the guideline restricts the free choice of therapy, or they were afraid of recourse claims. Some considered the guideline as too cautious regarding treatment initiation, possibly delaying necessary therapies. Others appreciated that conflicts of interests of the guideline's authoring group were minimized and thought that the new guideline is clearer, more extensive and practical. CONCLUSION: In contrast to the survey, feedback in the focus group discussions and from individuals was diverse and sometimes more critical. Based on the overall feedback rate of about 250 people in relation to the number of 6500 board-certified neurologists in Germany, the overall appreciation of the guideline can only be considered as an indicator and not proof of acceptance. Results of this analysis were incorporated into several adjustments to the final guideline of 2021. Since the guideline is to be updated regularly under the auspices of a "living guideline", active interaction with users will continue to matter and help to improve it.

Decision-making about corticosteroids in relapses of multiple sclerosis - development of a questionnaire based on the theory of planned behaviour.

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.

[Autologous hematopoietic stem cell transplantation for autoimmune diseases : Current indications and mode of action, a review on behalf of the EBMT Autoimmune Diseases Working Party (ADWP)]. / Autologe hämatopoetische Stammzelltransplantation bei Autoimmunerkrankungen : Aktuelle Indikationen und Wirkungsweise, ein Review der EBMT Autoimmune Diseases Working Party (ADWP).

The recent introduction of biologic and targeted synthetic disease-modifying drugs has led to more specificity in the treatment of autoimmune diseases; however, they require continuous or intermittent administration, are associated with cumulative risks for side effects, result in high costs and provide no cure. In contrast, high-dose chemotherapy followed by transplantation of autologous hematopoietic stem cells (AHSCT) has been demonstrated to induce clinical remission in various autoimmune diseases that can persist over many years without continued maintenance therapy. The principle behind AHSCT is an elimination of important components of the autoreactive immunological memory with subsequent regeneration of the complete immune system. Several studies have indicated that such an immune reset is associated with fundamental changes in the immune repertoire leading to an induction of tolerance against self-antigens. This article presents the current indications of AHSCT for autoimmune diseases based on the registry data of the European Society of Blood and Marrow Transplantation (EBMT) and discusses the results from mechanistic studies, which provide detailed insights into the mode of action of this treatment.

Nurse-led immunotreatment DEcision Coaching In people with Multiple Sclerosis (DECIMS) - Feasibility testing, pilot randomised controlled trial and mixed methods process evaluation.

BACKGROUND: Treatment decision-making is complex for people with multiple sclerosis. Profound information on available options is virtually not possible in regular neurologist encounters. The "nurse decision coach model" was developed to redistribute health professionals' tasks in supporting immunotreatment decision-making following the principles of informed shared decision-making. OBJECTIVES: To test the feasibility of a decision coaching programme and recruitment strategies to inform the main trial. DESIGN: Feasibility testing and parallel pilot randomised controlled trial, accompanied by a mixed methods process evaluation. SETTING: Two German multiple sclerosis university centres. PARTICIPANTS PILOT TRIAL: People with suspected or relapsing-remitting multiple sclerosis facing immunotreatment decisions on first line drugs were recruited. Randomisation to the intervention (n = 38) or control group (n = 35) was performed on a daily basis. Quantitative and qualitative process data were collected from people with multiple sclerosis, nurses and physicians. METHODS: We report on the development and piloting of the decision coaching programme. It comprises a training course for multiple sclerosis nurses and the coaching intervention. The intervention consists of up to three structured nurse-led decision coaching sessions, access to an evidence-based online information platform (DECIMS-Wiki) and a final physician consultation. After feasibility testing, a pilot randomised controlled trial was performed. People with multiple sclerosis were randomised to the intervention or control group. The latter had also access to the DECIMS-Wiki, but received otherwise care as usual. Nurses were not blinded to group assignment, while people with multiple sclerosis and physicians were. The primary outcome was 'informed choice' after six months including the sub-dimensions' risk knowledge (after 14 days), attitude concerning immunotreatment (after physician consultation), and treatment uptake (after six months). Quantitative process evaluation data were collected via questionnaires. Qualitative interviews were performed with all nurses and a convenience sample of nine people with multiple sclerosis. RESULTS: 116 people with multiple sclerosis fulfilled the inclusion criteria and 73 (63%) were included. Groups were comparable at baseline. Data of 51 people with multiple sclerosis (70%) were available for the primary endpoint. In the intervention group 15 of 31 (48%) people with multiple sclerosis achieved an informed choice after six months and 6 of 20 (30%) in the control group. Process evaluation data illustrated a positive response towards the coaching programme as well as good acceptance. CONCLUSIONS: The pilot-phase showed promising results concerning acceptability and feasibility of the intervention, which was well perceived by people with multiple sclerosis, most nurses and physicians. Delegating parts of the immunotreatment decision-making process to trained nurses has the potential to increase informed choice and participation as well as effectiveness of patient-physician consultations.

Perceptions on the value of bodily functions in multiple sclerosis.

BACKGROUND: In neurological diseases presenting with a plethora of symptoms, the value of bodily functions for a given patient might be a guide for clinical management. Multiple sclerosis (MS) is paradigmatic in this respect, and little is known about the value of different bodily functions of patients and their physicians' perceptions. METHODS: In a multicenter study, 171 patients with relapsing-remitting multiple sclerosis (RRMS), 61% with a clinically active disease within the last 2 years were followed over up to 3 years and yearly patients and their study physician rated on the perceived value of 13 bodily functions via a priority list. Differences between patients and physicians as well as modulating disease demographic factors were analyzed. RESULTS: Patients with RRMS rated visual function followed by thinking and memory and walking highest while physicians stressed mobility, followed by thinking and memory and alertness most. Ratings were independent from disease duration or disability. Strongest value judgment differences were seen in swallowing regarded more relevant by patients and hand function regarded more relevant by physicians. In general, patients' and physicians' ratings through time were quite stable. Collapsing physical items into a physical functioning scale and mental items in a mental function scale, both dimensions were regarded equally important by patients while physicians underscored physical functioning (P = .016). CONCLUSION: There are differences between patients and physicians in value statements of bodily functions in MS. In particular, visual functioning is under-recognized by physicians.

Low clinical conversion rate in clinically isolated syndrome patients - diagnostic benefit of McDonald 2010 criteria?

BACKGROUND AND PURPOSE: New diagnostic criteria of multiple sclerosis (MS) increase the number of patients being diagnosed with MS whilst a substantial part might not convert to clinically definite MS (CDMS). The diagnostic accuracy of the McDonald 2005 and 2010 criteria for conversion to CDMS was evaluated in an unselected cohort of patients in whom an MS diagnostic work-up was decided. METHODS: Clinical, magnetic resonance imaging and cerebrospinal fluid data were analysed for all patients who presented with symptoms suspicious for MS at the university based MS outpatient clinic between 2006 and 2010 (n = 165). RESULTS: Follow-up was available for 131 patients. During the mean follow-up period of 2 years, 19% of patients developed CDMS whereas 64% of the patients fulfilling McDonald 2010 criteria did not convert to CDMS. CONCLUSION: The low clinical conversion rate indicates that the new diagnostic criteria may increase the incidence of MS cases with a less active disease course.

What should a person with relapsing-remitting multiple sclerosis know? - Focus group and survey data of a risk knowledge questionnaire (RIKNO 2.0).

BACKGROUND: Risk knowledge is relevant to make informed decisions in multiple sclerosis (MS). The risk knowledge questionnaire for relapsing-remitting MS (RIKNO 1.0) was developed and piloted in Germany. OBJECTIVE: To produce a revised RIKNO 2.0 questionnaire using mixed methodology in a European setting. METHODS: The questionnaire was translated in seven languages. MS patient and health professional (HP) expert feedback was obtained from Germany, Italy, Estonia, Serbia, and the UK. A German web-based survey of RIKNO 2.0 compared the tool with the MS Knowledge Questionnaire (MSKQ), each one used with two versions (with/without a "don't know" DN option). RESULTS: While RIKNO 2.0 was considered difficult, it was rated as highly educational. One item was reframed, and two new items were added. The web-based German survey (n = 708 completers) showed that the DN version did not increase participation rate and did not produce significantly higher scores. Internal consistency (Cronbach alpha) without SN response was 0.73. RIKNO 2.0 scores showed normality distribution irrespective of the answering format. Item difficulty was high ranging from 0.07 to 0.79. Less than 50% of questions were answered correctly (mean 8.9) compared to 80.4% in the MSKQ (mean 20.1). Higher numeracy competency and education were significantly, albeit weakly, associated to higher scores for both RIKNO 2.0 and MSKQ. CONCLUSION: Including "don't know" options in knowledge questionnaires does not increase percentage of correct replies. RIKNO 2.0 is a complex questionnaire to be used in an educational context and studies on patient information. The tool is now available in seven languages.

No relevant impact of ambient temperature on disability measurements in a large cohort of patients with multiple sclerosis.

BACKGROUND AND PURPOSE: Many patients with multiple sclerosis (MS) report a worsening of symptoms due to high ambient temperatures, but objective data about this association are rare and contradictory. The aim of this study was to investigate the influence of ambient temperature on standard clinical tests. METHODS: We extracted the Symbol Digit Modality Test, Nine Hole Peg Test, Timed 25 Foot Walk (T25FW), Timed Tandem Walk, Expanded Disability Status Scale (EDSS) and quality-of-life items on cognition, fatigue and depression from our clinical database and matched them to historical temperatures. We used linear mixed-effect models to investigate the association between temperature and outcomes. RESULTS: A total of 1254 patients with MS (mean age, 42.7 years; 69.9% females; 52.1% relapsing-remitting MS, mean EDSS, 3.8) had 5751 assessments between 1996 and 2012. We observed a worsening in the T25FW with higher ambient temperatures in moderately disabled patients (EDSS ≥ 4) but not in less disabled patients. However, an increase of 10°C prolonged the T25FW by just 0.4 s. Other outcomes were not associated with ambient temperatures. CONCLUSIONS: Higher ambient temperature might compromise walking capabilities in patients with MS with a manifest walking impairment. However, effects are small and not detectable in mildly disabled patients. Hand function, cognition, mood and fatigue do not appear to be correlated with ambient temperature.

T1 Recovery Is Predominantly Found in Black Holes and Is Associated with Clinical Improvement in Patients with Multiple Sclerosis.

BACKGROUND AND PURPOSE: Quantitative MR imaging parameters help to evaluate disease progression in multiple sclerosis and increase correlation with clinical disability. We therefore hypothesized that T1 values might be a marker for ongoing tissue damage or even remyelination and may help increase clinical correlation. MATERIALS AND METHODS: MR imaging was performed in 17 patients with relapsing-remitting MS at baseline and after 12 months of starting immunotherapy with dimethyl fumarate. On baseline images, lesion segmentation was performed for normal-appearing white matter, T2 hyperintense (FLAIR lesions), T1 hypointense (black holes), and contrast-enhancing lesions, and T1 relaxation times were obtained at baseline and after 12 months. Changes in clinical status were assessed by using the Expanded Disability Status Scale and Symbol Digit Modalities Test at both dates (Expanded Disability Status Scale-difference/Symbol Digit Modalities Test-diff). RESULTS: The highest T1 relaxation time at baseline was measured in black holes (1460.2 ± 209.46 ms) followed by FLAIR lesions (1400.38 ± 189.1 ms), pure FLAIR lesions (1327.5 ± 210.04 ms), contrast-enhancing lesions (1205.59 ± 199.95 ms), and normal-appearing white matter (851.34 ± 30.61 ms). After 12 months, T1 values had decreased significantly in black holes (1369.4 ± 267.81 ms), contrast-enhancing lesions (1079.57 ± 183.36 ms) (both P < .001), and normal-appearing white matter (841.98 ± 36.1 ms, P = .006). With the Jonckheere-Terpstra Test, better clinical scores were associated with decreasing T1 relaxation times in black holes (P < .05). CONCLUSIONS: T1 relaxation time is a useful quantitative MR imaging technique, which helps detect changes in MS lesions with time. We assume that these changes are associated with the degree of myelination within the lesions themselves and are pronounced in black holes. Additionally, decreasing T1 values in black holes were associated with clinical improvement.

Patient education programme on immunotherapy in multiple sclerosis (PEPIMS): a controlled rater-blinded study.

OBJECTIVE: To investigate the effectiveness of a multi-component evidence-based education programme on disease modifying therapies in multiple sclerosis. DESIGN: Controlled trial with two consecutive patient cohorts and a gap of two months between cohorts. SETTING: Three neurological rehabilitation centres. SUBJECTS: Patients with multiple sclerosis within rehabilitation. INTERVENTIONS: Control group (CG) participants were recruited and received standard information. Two months later, intervention group (IG) participants were recruited and received a six-hour nurse-led interactive group education programme consisting of two parts and a comprehensive information brochure. MAIN MEASURES: Primary endpoint was "informed choice", comprising of adequate risk knowledge in combination with congruency between attitude towards immunotherapy and actual immunotherapy uptake. Further outcomes comprised risk knowledge, decision autonomy, anxiety and depression, self-efficacy, and fatigue. RESULTS: A total of 156 patients were included (IG=75, CG=81). The intervention led to significantly more participants with informed choice (IG: 47% vs. CG: 23%, P=0.004). The rate of persons with adequate risk knowledge was significantly higher in the IG two weeks after the intervention (IG: 54% vs. CG: 31%, P=0.007), but not after six months (IG: 48% vs. CG: 31%, P=0.058). No significant differences were shown for positive attitude towards disease modifying therapy (IG: 62% vs. CG: 71%, P=0.29) and for disease modifying therapy status after six months (IG: 61.5% vs CG: 68.6%, P=0.39). Also no differences were found for autonomy preferences and decisional conflict after six months. CONCLUSION: Delivering evidence-based information on multiple sclerosis disease modifying therapies within a rehabilitation setting led to a marked increase of informed choices.

Improved Lesion Detection by Using Axial T2-Weighted MRI with Full Spinal Cord Coverage in Multiple Sclerosis.

BACKGROUND AND PURPOSE: Identification of lesions in specific locations gains importance in multiple sclerosis imaging diagnostic criteria. In clinical routine, axial scans are usually exclusively obtained to depict the cervical spinal cord or used to confirm suspected lesions on sagittal scans. We sought to evaluate the detection rate for MS lesions on axial T2WI scans with full spinal cord coverage in comparison with sagittal scans. MATERIALS AND METHODS: One hundred fifteen patients with definite or suspected MS underwent an MR imaging examination including 3-mm sagittal and 3.5-mm axial T2-weighted images with full spinal cord coverage. T2WI lesions were identified on axial and sagittal scans independently by 2 raters. Axial diameter, craniocaudal extension, lesion intensity, and location were analyzed. RESULTS: Four hundred forty-nine of 509 (88.2%) lesions were detected on axial and 337/509 (66.2%) on sagittal scans. Only 277/449 (61.7%) axial lesions were also detected on sagittal images. The number of lesions visible on sagittal and axial images was dependent on the axial lesion diameter (P < .001). CONCLUSIONS: Axial T2WI scans with full spinal cord coverage showed 22% more lesions in patients with MS in comparison with sagittal scans, especially for lesions with small axial diameters. We suggest including biplanar spinal MR imaging with full spinal cord coverage for lesion detection in MS in clinical routine and for clinical studies.

Chronic T2 Lesions in Multiple Sclerosis are Heterogeneous Regarding Phase MR Imaging.

PURPOSE: Phase imaging provides additional information on multiple sclerosis (MS) lesions and may in combination with mean diffusivity (MD) and magnetization transfer ratio (MTR) help differentiating heterogeneity of MS lesion pathology. METHODS: Magnetic resonance imaging (MRI) was performed in 23 MS patients including diffusion tensor imaging (DTI), magnetization transfer imaging (MTI), and SWI. Mean values (MTR, MD, and homodyne filtered phase) from 138 chronic MS lesions and normal appearing white matter (NAWM) were obtained and correlations examined. For explorative analysis, a divisive hierarchical clustering algorithm was applied. RESULTS: Phase characteristics were an independent characteristic of chronic T2 lesions, as MTR and MD were not correlated with phase values (R = - 0.23, R = - 0.18). Dependent on MTR, MD, and phase, cluster analysis led to five lesion groups. Of the two groups with phase values close to NAWM, one presented with highest MD and most severe MTR decrease (p = 0.01), the other with slight MD increase and MTR decrease. Two lesion groups with highest phase values (p = 0.01) displayed slightly increased MD and moderate decrease in MTR. Clinical data including EDSS, disease duration, and age did not differ significantly between groups. CONCLUSIONS: Increased phase is predominantly detectable in lesions with clear MTR decrease but only moderate MD increase. Phase images seem to represent an independent parameter for MS lesion characterization and may provide additional information on MS lesion heterogeneity.

Risk Knowledge in Relapsing Multiple Sclerosis (RIKNO 1.0)--Development of an Outcome Instrument for Educational Interventions.

BACKGROUND: Adequate risk knowledge of patients is a prerequisite for shared decision making but few attempts have been made to develop assessment tools. Multiple Sclerosis (MS) is a chronic inflammatory disease of young adults with an increasing number of partially effective immunotherapies and therefore a paradigmatic disease to study patient involvement. OBJECTIVE/METHODS: Based on an item bank of MS risk knowledge items and patient feedback including perceived relevance we developed a risk knowledge questionnaire for relapsing remitting (RR) MS (RIKNO 1.0) which was a primary outcome measure in a patient education trial (192 early RRMS patients). RESULTS: Fourteen of the RIKNO 1.0 multiple-choice items were selected based on patient perceived relevance and item difficulty indices, and five on expert opinion. Mean item difficulty was 0.58, ranging from 0.14 to 0.79. Mean RIKNO 1.0 score increased after the educational intervention from 10.6 to 12.4 (p = 0.0003). Selected items were particularly difficult (e.g. those on absolute risk reductions of having a second relapse) and were answered correctly in only 30% of the patients, even after the intervention. CONCLUSION: Despite its high difficulty, RIKNO 1.0 is a responsive instrument to assess risk knowledge in RRMS patients participating in educational interventions.

[Stem cell transplantation for multiple sclerosis. Hamburg experiences and state of international research]. / Stammzelltransplantation bei Multipler Sklerose. Hamburger Erfahrungen und internationaler Forschungsstand.

BACKGROUND: Autologous hematopoietic stem cell transplantation (aHSCT) is still not the standard treatment for highly inflammatory multiple sclerosis (MS). Even though randomized controlled trials are lacking, predictors for treatment response have been established. Since 2007, ten patients have received aHSCT in Hamburg. OBJECTIVE: To present observational data from patients treated in Hamburg and a review of the literature. METHODS: Descriptive statistics were used for evaluating the course of the expanded disability status scale (EDSS) as a measure for clinical outcome, magnetic resonance imaging (MRI) and neuropsychology. New gadolinium and T2-MRI uptake lesions per scan were compared. In addition, a systematic review of the currently available literature was performed. RESULTS: The Hamburg series can be divided in two groups, one group including four patients with chronic progressive MS with low inflammatory activity (median EDSS = 6.25, 0.5 relapses per year, no gadolinium-enhancing lesions) and the other group including six patients with mild to moderate disability, relapses and inflammatory activity (median EDSS = 4.25, 1 relapse per year, 2 gadolinium-enhancing lesions). The median follow-up was 2.4 years. While the first group did not seem to benefit from aHSCT, an improvement in five out of six patients was observed in the second group. New T2 lesions occurred within the first 6 months but gadolinium-enhancing lesions were not observed (p < 0.05). A systematic literature search identified a higher efficacy of aHSCT in younger, less disabled MS patients with inflammatory activity, similar to the findings from Hamburg. CONCLUSION: Cohort reports describe aHSCT as a safe and efficient treatment option in highly inflammatory MS. Based on these data aHSCT seems to be a reasonable option in selected patients with highly inflammatory MS but a randomized controlled trial is warranted.
