A case of longitudinally extensive transverse myelitis in an 80-year-old patient with systemic lupus erythematous and anti-aquaporin 4 antibodies.

BACKGROUND: Systemic Lupus Erythematous is a systemic autoimmune disease with multiorgan inflammation. Clinical manifestations are variable and may involve the Central Nervous System. Acute transverse myelitis is a rare complication. Recent studies have shown an association between SLE, transverse myelitis and presence of anti-aquaporin 4 antibodies. CASE PRESENTATION: We describe the case of an 80-year-old woman with a subacute onset of right hemiplegia followed by left-sided ataxia. Cervical MRI revealed longitudinally extensive transverse myelitis. Blood examinations showed positivity for anti-nuclear antibodies, anti-double-stranded DNA antibodies, anti-phospholipid antibodies and anti-aquaporin 4 antibodies. CONCLUSIONS: Anti-aquaporin 4 antibody testing is of paramount importance in order to reach a correct diagnosis and to treat patients with the best therapeutic approach.

Two-year real-life efficacy, tolerability and safety of dimethyl fumarate in an Italian multicentre study.

BACKGROUND: Dimethyl-fumarate (DMF) demonstrated efficacy and safety in relapsing-remitting multiple sclerosis (MS) in randomized clinical trials. OBJECTIVES: To track and evaluate post-market DMF profile in real-world setting. MATERIALS AND METHODS: Patients receiving DMF referred to Italian MS centres were enrolled and prospectively followed, collecting demographic clinical and radiological data. RESULTS: Among the 735 included patients, 45.4% were naïve to disease-modifying therapies, 17.8% switched to DMF because of tolerance, 27.4% switched to DMF because of lack of efficacy, and 9.4% switched to DMF because of safety concerns. Median DMF exposure was 17 months (0-33). DMF reduced the annual relapse rate (ARR) by 63.2%. At 12 and 24 months, 85 and 76% of patients were relapse-free. NEDA-3 status after 12 months of DMF treatment was maintained by 47.5% of patients. 89 and 70% of patients at 12 and 24 months regularly continued DMF. Most frequent adverse events (AEs) were flushing (37.2%) and gastro-enteric AEs (31.1%). CONCLUSION: Our post-market study corroborated that DMF is a safe and effective drug. Additionally, the study suggested that naïve patients strongly benefit from DMF and that DMF improved ARR also in patients who were horizontally switched from injectable therapies due to tolerability and efficacy issues.

Outcome in lacunar stroke: A cohort study.

OBJECTIVES: We evaluated a prospective cohort of 150 patients under observation in our centre for lacunar strokes. The purpose of this study was to evaluate the outcome at time of discharge and 6 months after lacunar stroke, as well as the correlation with cardiovascular risk factors and selected biochemical parameters already evaluated on admission. Focus was to identify possible prognostic factors, which might be targeted through appropriate intervention concentrating on reduction in the incidence and impact of early clinical deterioration. METHODS: 150 patients with a lacunar stroke were included in the present study. A clinical 6-month follow-up was available for 98.7% of the patients. Infarcts were classified by size, shape and location. RESULTS: The most important predictors of high NIHSS score at time of discharge resulted NIHSS on admission (P < .001), leukocytosis (P = .013), in-hospital infections (P = .016) and size of lacunae (P = .005). Similarly, the most important predictors of poor outcome 6 months later were NIHSS on admission (P = .01), leukocytosis (P = .014), elevated CRP (P = .019), in addition to pre-admission Rankin (P < .001). CONCLUSION: Although infections are not causatively related to lacunar strokes, their prompt recognition and early treatment, control of inflammatory markers and fever are most important in influencing functional outcome in lacunar stroke.

HLA-DRB1*15 association with multiple sclerosis is confirmed in a multigenerational Italian family.

Environmental and genetic factors seem to play a pathogenetic role in multiple sclerosis (MS). The genetic component is partly suggested by familial aggregation of cases; however, MS families with affected subjects over different generations have rarely been described. The aim of this study was to report clinical and genetic features of a multigenerational MS family and to perform a review of the literature on this topic. We describe a multigenerational Italian family with six individuals affected by MS, showing different clinical and neuroradiological findings. HLA-DRB1* typing revealed the presence of the DRB1*15:01 allele in all the MS cases and in 4/5 non-affected subjects. Reports on six multigenerational MS families have previously been published, giving similar results. The HLA-DRB1*15:01 allele was confirmed to be linked to MS disease in this family; moreover, its presence in non-affected subjects suggests the involvement of other susceptibility factors in the development and expression of the disease, in accordance with the complex disease model now attributed to MS.

Novel FUS mutations identified through molecular screening in a large cohort of familial and sporadic amyotrophic lateral sclerosis.

BACKGROUND AND PURPOSE: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease. Approximately 5%-10% of cases are familial (FALS) and the remaining are sporadic (SALS). To date FUS mutations are responsible for 4%-6% of familial cases as well as 0.7%-1.8% of sporadic cases. METHODS: The frequency of FUS mutations was investigated in an Italian cohort of 500 SALS and 40 FALS patients through direct sequencing of exons 5, 6, 13, 14 and 15. RESULTS: Eight FUS mutation carriers were identified in five SALS (1%) and three FALS (7.5%), five already known and three new mutations: a de novo mutation was identified in a sporadic subject as well as the co-presence of FUS/C9ORF72 mutations in a FALS subject. The molecular and clinical details of the three patients harbouring a novel mutation (G245V, G509D and R491C) are presented here. Moreover the co-presence of the R491C mutation and C9ORF72 pathological expansion was found according to the oligogenic disease model. CONCLUSIONS: In conclusion our results revealed a higher frequency of FUS mutation carriers (7.5%) in FALS compared to literature data together with a higher presence of female gender.
