Abstract

Background: There are few head-to-head studies to compare highly active treatments in multiple sclerosis (MS) Objective: The aim of this study was to compare the effectiveness between natalizumab (NTZ) and fingolimod (FTY) in active relapsing–remitting MS Method: Best Escalation STrategy in Multiple Sclerosis (BEST-MS) is a multicentric, prospective study with a 12-month follow-up including patients with active MS. Treatment choice was at the discretion of physician. Clinical and magnetic resonance imaging (MRI) data were collected at baseline and at 12 months. The primary outcome was the proportion of patients reaching no evidence of disease activity (NEDA) at 12 months. Secondary outcomes included annualized relapse rate and MRI activity. Results: A total of 223 patients were included (NTZ: 109 and FTY: 114). Treatment groups were well balanced at baseline. Proportion of NEDA patients was 47.8% in NTZ group versus 30.4% in FTY group ( p = 0.015). This superiority was driven by annualized relapse rate and MRI activity. In the multivariate analysis, treatment group was the only factor associated with NEDA at 12 months with a lower probability in FTY group (odds ratio (OR) = 0.49, p = 0.029). Conclusion: BEST-MS is a prospective study that compared head-to-head the effectiveness of NTZ and FTY in active relapsing–remitting MS. Our results suggest a superiority of NTZ over FTY.

Abstract

International audience; Importance:Risk of developing progressive multifocal leukoencephalopathy (PML) is the major barrier to using natalizumab for patients with multiple sclerosis (MS). To date, the association of risk stratification with PML incidence has not been evaluated.Objective:To describe the temporal evolution of PML incidence in France before and after introduction of risk minimization recommendations in 2013.Design, Setting, and Participants:This observational study used data in the MS registry OFSEP (Observatoire Français de la Sclérose en Plaques) collected between April 15, 2007, and December 31, 2016, by participating MS expert centers and MS-dedicated networks of neurologists in France. Patients with an MS diagnosis according to current criteria, regardless of age, were eligible, and those exposed to at least 1 natalizumab infusion (n = 6318) were included in the at-risk population. A questionnaire was sent to all centers, asking for a description of their practice regarding PML risk stratification. Data were analyzed in July 2018.Exposures:Time from the first natalizumab infusion to the occurrence of PML, natalizumab discontinuation plus 6 months, or the last clinical evaluation.Main Outcomes and Measures:Incidence was the number of PML cases reported relative to the person-years exposed to natalizumab. A Poisson regression model for the 2007 to 2016 period estimated the annual variation in incidence and incidence rate ratio (IRR), adjusted for sex and age at treatment initiation and stratified by period (2007-2013 and 2013-2016).Results:In total, 6318 patients were exposed to natalizumab during the study period, of whom 4682 (74.1%) were female, with a mean (SD [range]) age at MS onset of 28.5 (9.1 [1.1-72.4]) years; 45 confirmed incident cases of PML were diagnosed in 22 414 person-years of exposure. The crude incidence rate for the whole 2007 to 2016 period was 2.00 (95% CI, 1.46-2.69) per 1000 patient-years. Incidence significantly increased by 45.3% (IRR, 1.45; 95% CI, 1.15-1.83; P = .001) each year before 2013 and decreased by 23.0% (IRR, 0.77; 95% CI, 0.61-0.97; P = .03) each year from 2013 to 2016.Conclusions and Relevance:The results of this study suggest, for the first time, a decrease in natalizumab-associated PML incidence since 2013 in France that may be associated with a generalized use of John Cunningham virus serologic test results; this finding appears to support the continuation and reinforcement of educational activities and risk-minimization strategies in the management of disease-modifying therapies for multiple sclerosis.

Abstract

Background Longitudinally extensive transverse myelitis (LETM) is classically related to aquaporin (AQP4)-antibodies (Ab) neuromyelitis optica spectrum disorders (NMOSD) or more recently to myelin oligodendrocyte glycoprotein (MOG)-Ab associated disease. However, some patients remain negative for any diagnosis, despite a large work-up including AQP4-Ab and MOG-Ab. Data about natural history, disability outcome, and treatment are limited in this group of patients. We aimed to (1) describe clinical, biological, and radiological features of double seronegative LETM patients; (2) assess the clinical course and identify prognostic factors; and (3) assess the risk of recurrence, according to maintenance immunosuppressive therapy. Methods Retrospective evaluation of patients with a first episode of LETM, tested negative for AQP-Ab and MOG-Ab, from the French nationwide observatory study NOMADMUS. Results Fifty-three patients (median age 38 years (range 16–80)) with double seronegative LETM were included. Median nadir EDSS at onset was 6.0 (1–8.5), associated to a median EDSS at last follow-up of 4.0 (0–8). Recurrence was observed in 24.5% of patients in the 18 following months, with a median time to first relapse of 5.7 months. The risk of recurrence was lower in the group of patients treated early with an immunosuppressive drug (2/22, 9%), in comparison with untreated patients (10/31, 32%). Conclusions A first episode of a double seronegative LETM is associated to a severe outcome and a high rate of relapse in the following 18 months, suggesting that an early immunosuppressive treatment may be beneficial in that condition.

Abstract

Isolated tumefactive demyelinating lesion (TDL) is a rare disease and a challenging entity especially for the differential diagnosis, biopsy indications, and therapeutic decisions. Long-term evolution is not well known. The objective of the study is to describe clinical and MRI characteristics and long-term follow-up of patients with isolated TDL. We performed a retrospective study including patients (1) with one TDL radiologically defined by a ≥20 mm FLAIR hyperintensity involving the white matter associated with T1 hypointensity that enhanced after gadolinium injection and (2) without any other MS lesion on the first MRI. Tumor, abscess, or other inflammatory diseases (ADEM, Balo’s concentric sclerosis, systemic disease) were excluded. Sixteen patients (11 females/5 males) were included. The mean age of onset was 35.7 years (range 20–65). MRI disclosed supratentorial lesions with a mean size of 39.4 mm and usually mild edema/mass effect. Peripheral (mainly open-ring pattern) and central (mainly heterogeneous) enhancement were respectively seen in 9/16 and 11/16 patients. CSF study (n = 15) found oligoclonal bands (OCB) in seven. A cerebral biopsy was performed in 11 cases showing acute inflammatory demyelination. Thirteen patients were treated by pulse steroids with marked improvement in ten. At last clinical follow-up (mean 65.8 months, range 6–181), diagnosis was MS in 5 (31 %), isolated TDL in 10 (63 %) and one patient had a second TDL (6 %). Isolated tumefactive demyelinating lesions are a rare diagnostic entity. After a mean follow-up of 5 years, almost one-third became MS whereas most of the patients had no further event.

Abstract

International audience; Idiopathic basal ganglia calcification is characterized by mineral deposits in the brain, an autosomal dominant pattern of inheritance in most cases and genetic heterogeneity. The first causal genes, SLC20A2 and PDGFRB, have recently been reported. Diagnosing idiopathic basal ganglia calcification necessitates the exclusion of other causes, including calcification related to normal ageing, for which no normative data exist. Our objectives were to diagnose accurately and then describe the clinical and radiological characteristics of idiopathic basal ganglia calcification. First, calcifications were evaluated using a visual rating scale on the computerized tomography scans of 600 consecutively hospitalized unselected controls. We determined an age-specific threshold in these control computerized tomography scans as the value of the 99th percentile of the total calcification score within three age categories: 60 years. To study the phenotype of the disease, patients with basal ganglia calcification were recruited from several medical centres. Calcifications that rated below the age-specific threshold using the same scale were excluded, as were patients with differential diagnoses of idiopathic basal ganglia calcification, after an extensive aetiological assessment. Sanger sequencing of SLC20A2 and PDGFRB was performed. In total, 72 patients were diagnosed with idiopathic basal ganglia calcification, 25 of whom bore a mutation in either SLC20A2 (two families, four sporadic cases) or PDGFRB (one family, two sporadic cases). Five mutations were novel. Seventy-one per cent of the patients with idiopathic basal ganglia calcification were symptomatic (mean age of clinical onset: 39 ± 20 years; mean age at last evaluation: 55 ± 19 years). Among them, the most frequent signs were: cognitive impairment (58.8%), psychiatric symptoms (56.9%) and movement disorders (54.9%). Few clinical differences appeared between SLC20A2 and PDGFRB mutation carriers. Radiological analysis revealed that the total calcification scores correlated positively with age in controls and patients, but increased more rapidly with age in patients. The expected total calcification score was greater in SLC20A2 than PDGFRB mutation carriers, beyond the effect of the age alone. No patient with a PDGFRB mutation exhibited a cortical or a vermis calcification. The total calcification score was more severe in symptomatic versus asymptomatic individuals. We provide the first phenotypical description of a case series of patients with idiopathic basal ganglia calcification since the identification of the first causative genes. Clinical and radiological diversity is confirmed, whatever the genetic status. Quantification of calcification is correlated with the symptomatic status, but the location and the severity of the calcifications don't reflect the whole clinical diversity. Other biomarkers may be helpful in better predicting clinical expression.

Abstract

In the era of disease modifying treatments, little is known about conversion to the progressive phase (SP-MS) in relapsing-remitting multiple sclerosis (RR-MS) patients. The objective of the study is to identify the factors influencing the rate and the delay of a conversion to SP form within 11 years. The study was retrospective and bi-centered. The data was extracted from Observatoire Français de la SEP registry (Caen and Rouen university hospital). 629 patients were included in the « non-converter group » and 120 in the « converter group ». The « converter group » had-fewer women (65% vs. 74.4%; p=0.008) - a greater mean age at onset (35.45 +/- 8.83 years vs 28.66 +/- 9.49 years; p 2 or ≥3 relapses in the first two years (25.83% vs 21.30%; p=0.039 and 17.5% vs 11.13%; p=0.009 respectively) and a lower number of patients treated with first-line treatment (TPL) +/- associated with second-line treatment (24.17% vs 34.5%, p 2 ou ≥3 poussées dans les deux premières années (25,8 3% vs 21,30 % ; p=0,039 et 17,5 % vs 11,13 % ; p=0,009 respectivement) et un nombre moins élevé de patients traités par un traitement de première ligne (TPL) +/- associée à un traitement de seconde ligne (24,17 % vs 34,5 % ; p
