Multiple sclerosis or neuromyelitis optica? Re-evaluating an 18th-century illness using 21st-century software
In this paper we report the application of an extensive database of symptoms, signs, laboratory findings and illnesses, to the diagnosis of an historical figure. The medical diagnosis of Augustus d'Este (1794â1848) â widely held to be the first documented case of multiple sclerosis â is reviewed, using the detailed symptom diary, which he kept over many years, as clinical data. Some of the reported features prompted the competing claim that d'Este suffered from acute porphyria, which in turn was used in support of the hypothesis that his grandfather, King George III, also suffered from the disease. We find that multiple sclerosis is statistically the most likely diagnosis, with neuromyelitis optica a strong alternative possibility. The database did not support a diagnosis of any of the acute porphyrias

Superior MRI outcomes with alemtuzumab compared with subcutaneous interferon β-1a in MS
To describe detailed MRI results from 2 head-to-head phase III trials, Comparison of Alemtuzumab and Rebif Efficacy in Multiple Sclerosis Study I (CARE-MS I; NCT00530348) and Study II (CARE-MS II; NCT00548405), of alemtuzumab vs subcutaneous interferon β-1a (SC IFN-β-1a) in patients with active relapsing-remitting multiple sclerosis (RRMS).
The impact of alemtuzumab 12 mg vs SC IFN-β-1a 44 Οg on MRI measures was evaluated in patients with RRMS who were treatment-naive (CARE-MS I) or who had an inadequate response, defined as at least one relapse, to prior therapy (CARE-MS II).
Both treatments prevented T2-hyperintense lesion volume increases from baseline. Alemtuzumab was more effective than SC IFN-β-1a on most lesion-based endpoints in both studies ( < 0.05), including decreased risk of new/enlarging T2 lesions over 2 years and gadolinium-enhancing lesions at year 2. Reduced risk of new T1 lesions ( < 0.0001) and gadolinium-enhancing lesion conversion to T1-hypointense black holes ( = 0.0078) were observed with alemtuzumab vs SC IFN-β-1a in CARE-MS II. Alemtuzumab slowed brain volume loss over 2 years in CARE-MS I ( < 0.0001) and II ( = 0.012) vs SC IFN-β-1a.
Alemtuzumab demonstrated greater efficacy than SC IFN-β-1a on MRI endpoints in active RRMS. The superiority of alemtuzumab was more prominent during the second year of both studies. These findings complement the superior clinical efficacy of alemtuzumab over SC IFN-β-1a in RRMS.
NCT00530348 and NCT00548405.
The results reported here provide Class I evidence that, for patients with active RRMS, alemtuzumab is superior to SC IFN-β-1a on multiple MRI endpoints.Dr. Havrdova was supported by the Czech Ministry of Education, PRVOUK-P26/LF1/4.

Investigating domain-specific cognitive impairment among patients with multiple sclerosis using touchscreen cognitive testing in routine clinical care
Cognitive dysfunction is present in up to 70% of patients with multiple sclerosis (MS) and has been reported at all stages and in all subtypes of the disease. These deficits have been reported across a variety of cognitive domains, but are generally under-recognized and incompletely evaluated in routine clinical practice. The aim of this study was to investigate the spectrum of cognitive impairment in patients with MS presenting to a specialist MS clinic using the Cambridge Neuropsychological Test Automated Battery (CANTAB), administered on a touchscreen platform. Ninety MS patients completed computerized CANTAB tasks assessing working memory, executive function, processing speed, attention, and episodic memory. Scores were adjusted for age, sex, and level of education and classified as normal or impaired based on comparison with a large normative data pool. We also investigated the impact of clinical and demographic variables which could potentially influence cognitive performance including patient educational level (a proxy for cognitive reserve), disease status (duration, course, and severity of MS), and depression. CANTAB testing detected cognitive impairment in 40 patients (44% of the sample). The most frequently impaired domain was executive function, present in 55% of cognitively impaired individuals. Disease duration and severity were significantly associated with performance across various cognitive domains. Patients with depressive symptoms were also more likely to exhibit impaired processing speed. Results from this study confirm that cognitive impairment is common and occurs across a range of domains among MS patients attending routine clinical visits. CANTAB tasks provide a sensitive and practical approach to cognitive testing in MS patients as part of a holistic patient assessment

Alemtuzumab CARE-MS I 5-year follow-up: Durable efficacy in the absence of continuous MS therapy
: Evaluate 5-year efficacy and safety of alemtuzumab in treatment-naive patients with active relapsing-remitting multiple sclerosis (RRMS).
: Alemtuzumab-treated patients in CARE-MS I (NCT00530348) received treatment courses at Months 0 and 12; after the core study, they could enter an extension (NCT00930553) with as-needed alemtuzumab retreatment for relapse or MRI activity. Assessments included annualized relapse rate (ARR), 6-month confirmed disability worsening (CDW; âĽ1-point Expanded Disability Status Scale [EDSS] score increase [âĽ1.5 if baseline EDSS = 0]), 6-month confirmed disability improvement (CDI; âĽ1-point EDSS decrease [baseline score âĽ2.0]), no evidence of disease activity (NEDA), brain volume loss (BVL), and adverse events (AEs).
: Most alemtuzumab-treated patients (95.1%) who completed CARE-MS I enrolled in the extension; 68.5% received no additional alemtuzumab treatment. ARR remained low in Years 3, 4, and 5 (0.19, 0.14, 0.15). Over Years 0â5, 79.7% were free of 6-month CDW; 33.4% achieved 6-month CDI. Most patients (61.7%, 60.2%, 62.4%) had annual NEDA in Years 3, 4, and 5. Median yearly BVL improved over Years 2â4, and remained low in Year 5 (Year 1â5: â0.59%, â0.25%, â0.19%, â0.15%, â0.20%). Exposure-adjusted incidence rates of most AEs declined in the extension relative to the core study. Thyroid disorder incidences peaked at Year 3 and subsequently declined.
: Based on these data, alemtuzumab has the potential to provide durable efficacy through 5 years in the absence of continuous treatment.
: This study provides Class III evidence that alemtuzumab durably improves efficacy outcomes and slows BVL in RRMS patients.Supported by Sanofi Genzyme and Bayer HealthCare Pharmaceuticals
Complement is activated in progressive multiple sclerosis cortical grey matter lesions
The symptoms of multiple sclerosis (MS) are caused by damage to myelin and nerve cells in the brain and spinal cord. Inflammation is tightly linked with neurodegeneration, and it is the accumulation of neurodegeneration that underlies increasing neurological disability in progressive MS. Determining pathological mechanisms at play in MS grey matter is therefore a key to our understanding of disease progression
Rehabilitation before and after autologous haematopoietic stem cell transplantation (AHSCT) for patients with multiple sclerosis (MS): Consensus guidelines and recommendations for best clinical practice on behalf of the autoimmune diseases working party, nurses group, and patient advocacy committee of the European Society for Blood and Marrow Transplantation (EBMT)
Autologous haematopoietic stem cell transplantation (AHSCT) is increasingly used to treat people with multiple sclerosis (MS). Supported by an evolving evidence base, AHSCT can suppress active inflammation in the central nervous system and induce long-term changes in immune cell populations, thereby stabilizing, and, in some cases, reversing disability in carefully selected MS patients. However, AHSCT is an intensive chemotherapy-based procedure associated with intrinsic risks, including profound cytopenia, infection, and organ toxicity, accompanied by an on-going degree of immuno-compromise and general deconditioning, which can be associated with a transient increase in functional impairment in the early stages after transplantation. Although international guidelines and recommendations have been published for clinical and technical aspects of AHSCT in MS, there has been no detailed appraisal of the rehabilitation needed following treatment nor any specific guidelines as to how this is best delivered by hospital and community-based therapists and wider multidisciplinary teams in order to maximize functional recovery and quality of life. These expert consensus guidelines aim to address this unmet need by summarizing the evidence-base for AHSCT in MS and providing recommendations for current rehabilitation practice along with identifying areas for future research and development
