Putative Mechanism

Background: Episodic hypothermia (EH) can occur in multiple sclerosis (MS). The putative mechanism is impairment of thermoregulation due to a presumed demyelinating hypothalamic lesion. Objective: To describe a cohort of patients with MS, who developed EH. Methods: Patients were identified through review of the Mayo Clinic electronic medical record (1996 to July 2015). Search terms were [multiple sclerosis] or [MS] within the diagnoses field and [hypothermia] within any field. We reviewed records for accuracy of diagnoses and abstracted relevant data. Magnetic resonance imaging (MRI) was reviewed for presence of hypothalamic lesions. Results: Of 156 patients, 34 had concurrent MS and hypothermia. Thirty-two (94%) had progressive disease at EH onset. Median MS duration was 19.9 years, and median expanded disability status scale (EDSS) was 8.0. Most patients presented with alterations in consciousness. Infection was suspected as the precipitating factor in 19 (56%), but clinically/laboratory supported in only 9 (28%). MRI lesions were evident within the hypothalamus in only 4 (14%). Conclusion: EH occurs predominantly in patients with advanced secondary progressive MS. The major manifestation is altered consciousness. Infection is often suspected as causal, but infrequently confirmed. Although commonly implicated, hypothalamic lesions were rarely evident on MRI and were absent in two post-mortem evaluations.

Over Time

The 2010 McDonald criteria allow the diagnosis of multiple sclerosis (MS) at first attack in children and adults provided that the first attack symptoms are typical of MS and that the magnetic resonance imaging (MRI) conforms to prescribed features. We evaluate whether meeting the 2010 McDonald criteria at onset correlates with a more aggressive clinical course in a cohort of pediatric MS patients. The Expanded Disability Status Scale (EDSS) and annualized relapse rate were not associated with positivity for 2010 McDonald criteria at onset. The 2010 McDonald criteria identify children with similar MS features to those identified by clinical or MRI evidence of dissemination over time.

Objective: To characterize neuropsychological (NP) test performance during multiple sclerosis (MS) relapse and recovery. Methods: Clinical status was assessed with NP testing and Expanded Disability Status Scale (EDSS) in 24 relapsing patients, and 24 individually-matched, stable controls. All presented with cognitive symptoms as indicated by patient, clinician or caregiver perceived decline, but were free of optic neuritis, ataxia and upper extremity weakness that could compromise NP testing. The presence of enhancing magnetic resonance imaging (MRI) lesions was considered confirmatory of relapse. Relapsing patients were treated with corticosteroids. NP testing and EDSS were compared to pre-relapse baseline levels, and three-month, post-relapse, follow-up. Results: Analyses revealed significant decline on the Symbol Digit Modalities Test (SDMT) ( p=0.005) and worsening on EDSS ( p=0.019). Impairment was observed at the point of relapse in cases but not controls. The groups were no longer different at three-month follow-up. The increment of decline on SDMT was 3.5 raw score points, or roughly 6%. Conclusions: This is the first study to assess NP status changes during MS relapse using well established, reliable metrics. The presence of a clinically meaningful event is substantiated by decline in NP testing, observed or reported cognitive change, and in a subset of patients, gadolinium-enhancing MRI lesions.

Background: Mesenchymal stem cells (MSCs) exhibit immunomodulatory, tissue-protective, and repair-promoting properties in vitro and in animals. Clinical trials in several human conditions support the safety and efficacy of MSC transplantation. Published experience in multiple sclerosis (MS) is modest. Objective: To assess feasibility, safety, and tolerability and explore efficacy of autologous MSC transplantation in MS. Methods: Participants with relapsing-remitting multiple sclerosis (RRMS) or secondary progressive multiple sclerosis (SPMS), Expanded Disability Status Scale score 3.0–6.5, disease activity or progression in the prior 2 years, and optic nerve involvement were enrolled. Bone-marrow-derived MSCs were culture-expanded and then cryopreserved. After confirming fulfillment of release criteria, 1–2 × 106 MSCs/kg were thawed and administered IV. Results: In all, 24 of 26 screened patients were infused: 16 women and 8 men, 10 RRMS and 14 SPMS, mean age 46.5, mean Expanded Disability Status Scale score 5.2, 25% with gadolinium-enhancing magnetic resonance imaging (MRI) lesions. Mean cell dosage (requiring 1–3 passages) was 1.9 × 106 MSCs/kg (range, 1.5–2.0) with post-thaw viability uniformly ⩾95%. Cell infusion was tolerated well without treatment-related severe or serious adverse events, or evidence of disease activation. Conclusion: Autologous MSC transplantation in MS appears feasible, safe, and well tolerated. Future trials to assess efficacy more definitively are warranted.

Objective:To determine the cumulative incidence of epilepsy in a population-based cohort of patients with multiple sclerosis (MS) and to investigate the association between epilepsy and clinical features of MS.Methods:All available patients in the Swedish MS register (n = 14,545) and 3 age- and sex-matched controls per patient randomly selected from the population register (n = 43,635) were included. Data on clinical features of MS were retrieved from the Swedish MS register, and data on epilepsy and death were retrieved from comprehensive patient registers.Results:The cumulative incidence of epilepsy was 3.5% (95% confidence interval [CI] 3.17–3.76) in patients with MS and 1.4% (95% CI 1.30–1.52) in controls (risk ratio 2.5, 95% CI 2.19–2.76). In a Cox proportional model, MS increased the risk of epilepsy (hazard ratio 3.2, 95% CI 2.64–3.94). Patients with relapsing-remitting MS had a cumulative incidence of epilepsy of 2.2% (95% CI 1.88–2.50), whereas patients with progressive disease had a cumulative incidence of 5.5% (95% CI 4.89–6.09). The cumulative incidence rose continuously with increasing disease duration to 5.9% (95% CI 4.90–7.20) in patients with disease duration ≥34 years. Patients with an Expanded Disability Status Scale (EDSS) score ≥7 had a cumulative incidence of epilepsy of 5.3% (95% CI 3.95–7.00). Disease duration and EDSS score were associated with epilepsy after multiple logistic regression (odds ratio [OR] 1.03, 95% CI 1.01–1.04 per year, p = 0.001; and OR 1.2, 95% CI 1.09–1.26 per EDSS step, p < 0.0001).Conclusions:Epilepsy is more common among patients with MS than in the general population, and a diagnosis of MS increases the risk of epilepsy. Our data suggest a direct link between severity of MS and epilepsy.

T2 hypointensity (black T2, BT2) in the deep grey matter of multiple sclerosis (MS) patients correlate weakly with disability at 1.5 T. BT2 is likely to be caused by abnormal iron deposition. We compared the correlation between disability and deep grey matter BT2 measured on 3 T MRI and on 1.5 T MRI in 17 MS patients. We observed a significant correlation between expanded disability status scale and signal intensity on 3 T MRI in the globus pallidus and the caudate nucleus ( r = —0.5, P < 0.05). BT2 at 3 T may be a useful MRI measure associated with disability in MS and warrants further study. Multiple Sclerosis 2007; 13: 880—883. http://msj.sagepub.com

Clinical Worsening

We aimed to single out multiple sclerosis (MS) cases with poor outcome after natalizumab withdrawal and to identify predictive variables. We ascertained 47 withdrawals, and compared their pre- and post-natalizumab periods. We objectively defined significant clinical worsening after natalizumab withdrawal as a 2-step increase in Expanded Disability Status Scale (EDSS). We performed regression models. As a group, post-natalizumab annualized relapse rate (ARR) was lower in the post-natalizumab period, and there were no differences in the mean number of gadolinium (Gd)-enhancing lesions between pre- and post-natalizumab magnetic resonance imaging (MRI). Corticosteroid treatment did not change the outcomes. Eight patients (19%) presented significant clinical worsening after natalizumab withdrawal, which was predicted by a higher baseline EDSS and a 1-step EDSS increase while on natalizumab.

Brainstem Dysfunction

Purpose The brainstem dysfunction in multiple sclerosis (MS) often causes significant functional impairment leading to disability. This study aims to explore modified brainstem auditory evoked potential (BAEP) scores based on the pattern of BAEP abnormalities and relate with brainstem symptoms, brainstem functional system scores (BFSS), brainstem lesions, and disability. Method Forty-five participants with relapsing–remitting MS and 45 age- and gender-matched healthy controls underwent case history assessment, otoscopic examination, pure-tone audiometry, and BAEP testing. Also, neurological examination (Expanded Disability Status Scale, FSS scales) and magnetic resonance imaging were carried out on MS participants. Patterns of BAEP abnormalities were categorized and converted to BAEP scores. Results Out of 45 participants' brainstem symptoms, BFSS > 1, brainstem lesions (magnetic resonance imaging), and BAEP abnormalities were observed in 75.6%, 42.2%, 62.2%, and 55.56% of participants, respectively. Waves V and III abnormalities were more common among MS participants and showed a significant difference from the control group in the Mann–Whitney U test. Chi-square test did not show a significant association of BAEP abnormalities with brainstem symptoms and lesions but showed significant association with BFSS. The mean and standard deviation of BAEP scores in MS participants were 1.73 + 2.37. All healthy controls showed BAEP scores of 0. BAEP scores in MS participants showed significant correlation with BFSS scores and predict Expanded Disability Status Scale scores. Conclusion BAEP scores based on the pattern of BAEP abnormality can be a valid and useful measure in evaluating brainstem functions and predicting disability in MS.

ABSTRACTObjectives: The objectives of this study were to assess the prevalence of temporomandibular disorders (TMDs) in patients with relapsing-remitting multiple sclerosis (MS) and to investigate whether an association exists between the presence of TMD symptoms and the degree of MS-related disability. Materials and Methods: In all, 120 individuals were evaluated: 60 patients with a diagnosis of relapsing-remitting MS and 60 age- and sex-matched controls without neurological impairments. A questionnaire recommended by the European Academy of Craniomandibular Disorders for the assessment of TMD symptoms was administered. For those who answered affirmatively to at least one of the questions, the RDC/TMD Axis I instrument was used for a possible classification of TMD subtypes. The Expanded Disability Status Scale (EDSS) was the measure of the degree of MS-related disability. Statistical Analysis Used: Fisher’s exact test was used to analyze the data. ANOVA was used to detect significant differences between means and to assess whether the factors influenced any of the dependent variables by comparing means from the different groups. Results: The prevalence of TMD symptoms in patients with MS was 61.7% versus 18.3% in the control group (CG). A diagnosis of TMD was established for 36.7% in the MS group and 3.3% in the CG (P = 0.0001). There were statistically significant differences between degrees of MS-related disability and the prevalence of TMD (P = 0.0288). Conclusions: The prevalence of both TMD and TMD symptoms was significantly greater in the MS group. EDSS scores and TMD prevalence rates were inversely related.

Background: A delayed onset of treatment effect, termed therapeutic lag, may influence the assessment of treatment response in some patient subgroups. Objectives: The objective of this study is to explore the associations of patient and disease characteristics with therapeutic lag on relapses and disability accumulation. Methods: Data from MSBase, a multinational multiple sclerosis (MS) registry, and OFSEP, the French MS registry, were used. Patients diagnosed with MS, minimum 1 year of exposure to MS treatment and 3 years of pre-treatment follow-up, were included in the analysis. Studied outcomes were incidence of relapses and disability accumulation. Therapeutic lag was calculated using an objective, validated method in subgroups stratified by patient and disease characteristics. Therapeutic lag under specific circumstances was then estimated in subgroups defined by combinations of clinical and demographic determinants. Results: High baseline disability scores, annualised relapse rate (ARR) ⩾ 1 and male sex were associated with longer therapeutic lag on disability progression in sufficiently populated groups: females with expanded disability status scale (EDSS) < 6 and ARR < 1 had mean lag of 26.6 weeks (95% CI = 18.2–34.9), males with EDSS < 6 and ARR < 1 31.0 weeks (95% CI = 25.3–36.8), females with EDSS < 6 and ARR ⩾ 1 44.8 weeks (95% CI = 24.5–65.1), and females with EDSS ⩾ 6 and ARR < 1 54.3 weeks (95% CI = 47.2–61.5). Conclusions: Pre-treatment EDSS and ARR are the most important determinants of therapeutic lag.
