    © 2018 National Stroke Association Background: The efficacy and safety of antiplatelet drugs in the treatment of moyamoya disease remain unclear. This study reports results of a nationwide survey conducted in 2016 on the trends of antiplatelet therapy for moyamoya disease in Japan. Methods: Data were obtained through questionnaires related to treatment policies regarding antiplatelet drugs from each specialized stroke management department of 765 hospitals in Japan. Data were also compared between experienced facilities (defined as facilities managing more than 10 cases per year) and those less experienced (not more than 10 cases per year) to determine experts' opinion. Results: Of the 389 departments in 375 hospitals that responded, 330 departments provided medical care for moyamoya disease. Regarding ischemic stroke, numerous departments considered the use of antiplatelet drugs “in principle” (218 departments). After surgery for ischemic moyamoya disease, the use of antiplatelet drugs for a certain period of time was the most popular opinion (74 departments). Regarding asymptomatic moyamoya disease, majority departments reported no use of APDs “in principle” (256 departments). The experienced facilities reported “no use of antiplatelet drugs” more frequently than those less experienced for treating asymptomatic moyamoya disease. In moyamoya disease, aspirin was the most commonly used antiplatelet drugs followed by cilostazol and clopidogrel. Conclusions: This survey revealed details of treatment policies, and the selection of antiplatelet drugs widely varied across facilities. Further prospective studies are necessary to improve the current unclear situation regarding the use of antiplatelet drugs for the management of moyamoya disease.

    Objective Coronary artery and cerebrovascular disease are the main causes of non-communicable diseases. In particular, acute coronary syndrome (ACS) and ischemic stroke are the most serious conditions of coronary artery disease and cerebrovascular disease, respectively. Therefore, it is important to prevent these conditions by identifying populations at high risk of these diseases. We sought to investigate the differences in the clinical features of patients with these atherothrombotic diseases in nationwide Japanese multicenter registries. Gender differences were also examined. Methods The dataset of the two nationwide multicenter registries for ACS [Prevention of AtherothrombotiC Incidents Following Ischemic Coronary (PACIFIC)] and ischemic stroke [Effective Vascular Event REduction after STroke (EVEREST)] was analyzed. Clinical features were examined and compared using datasets from the two registries. Results A total of 6,878 patients (PACIFIC: n=3,426, EVEREST: n=3,452) were evaluated. The patients' background characteristics were significantly different between the two populations. Patients with ACS tended to be younger, had a higher body mass index, had a greater prevalence of diabetes mellitus and dyslipidemia, were current smokers, and more often had a prior history of ischemia heart disease than patients with a stroke. Hypertension was more prevalent in patients with stroke than in those with ACS. The differences in patients' background characteristics between ACS and stroke in men were similar to those in the whole sample. However, the prevalence of hypertension in women was similar between the ACS and stroke groups, in contrast to the results from the whole sample. Conclusion Patients' background characteristics were significantly different between those with ACS and stroke. Gender differences were also observed.

    © International Headache Society 2017. Background: Patients with familial hemiplegic migraine type 2 (FHM2) have a mutated ATP1A2 gene (encoding Na+,K+-ATPase α2 subunit) and show prolonged migraine aura. Cortical spreading depression (CSD), which involves mass depolarization of neurons and astrocytes that propagates slowly through the gray matter, is profoundly related to aura. Methods: In two types of Atp1a2-defective heterozygous mice, Atp1a2tm1Kwk (C-KO) and Atp1a2tm2Kwk (N-KO), the sensitivity and responsiveness to CSD were examined under urethane anesthesia. Results: In both cases, heterozygotes exhibited a low threshold for induction of CSD, faster propagation rate, slower recovery from DC deflection, and profound suppression of the electroencephalogram, compared to wild-type mice. A high dose of KCl elicited repeated CSDs for a longer period, with a tendency for a greater frequency of CSD occurrence in heterozygotes. The difference of every endpoint was slightly greater in N-KO than C-KO. Change of regional cerebral blood flow in response to CSD showed no significant difference. Conclusion: Heterozygotes of Atp1a2-defective mice simulating FHM2 demonstrated high susceptibility to CSD rather than cortical vasoreactivity, and these effects may differ depending upon the knockout strategy for the gene disruption. These results suggest that patients with FHM2 may exhibit high susceptibility to CSD, resulting in migraine.

    © 2018 Elsevier Ltd Background: Despite the introduction of plasmapheresis and immunoglobulin therapy, many patients with Guillain-Barré syndrome still have an incomplete recovery. Evidence from pathogenesis studies suggests the involvement of complement-mediated peripheral nerve damage. We aimed to investigate the safety and efficacy of eculizumab, a humanised monoclonal antibody against the complement protein C5, in patients with severe Guillain-Barré syndrome. Methods: This study was a 24 week, multicentre, double-blind, placebo-controlled, randomised phase 2 trial done at 13 hospitals in Japan. Eligible patients with Guillain-Barré syndrome were aged 18 years or older and could not walk independently (Guillain-Barré syndrome functional grade 3–5). Patients were randomly assigned (2:1) to receive 4 weeks of intravenous immunoglobulin plus either eculizumab (900 mg) or placebo; randomisation was done via a computer-generated process and web response system with minimisation for functional grade and age. The study had a parallel non-comparative single-arm outcome measure. The primary outcomes were efficacy (the proportion of patients with restored ability to walk independently [functional grade ≤2] at week 4) in the eculizumab group and safety in the full analysis set. For the efficacy endpoint, we predefined a response rate threshold of the lower 90% CI boundary exceeding 50%. This trial is registered with ClinicalTrials.gov, number, NCT02493725. Findings: Between Aug 10, 2015, and April 21, 2016, 34 patients were assigned to receive either eculizumab (n=23) or placebo (n=11). At week 4, the proportion of the patients able to walk independently (functional grade ≤2) was 61% (90% CI 42–78; n=14) in the eculizumab group, and 45% (20–73; n=5) in the placebo group. Adverse events occurred in all 34 patients. Three patients had serious adverse events: two in the eculizumab group (anaphylaxis in one patient and intracranial haemorrhage and abscess in another patient) and one in the placebo group (depression). The possibility that anaphylaxis and intracranial abscess were related to eculizumab could not be excluded. No deaths or meningococcal infections occurred. Interpretation: The primary outcome measure did not reach the predefined response rate. However, because this is a small study without statistical comparison with the placebo group, the efficacy and safety of eculizumab could be investigated in larger, randomised controlled trials.

    © The Author(s) 2018. Oxidative stress plays an important role in the onset and progression of Parkinson disease. Although released dopamine at the synaptic terminal is mostly reabsorbed by dopaminergic neurons, some dopamine is presumably taken up by astroglia. This study examined the dopamine-induced astroglial protective function through the activation of the pentose-phosphate pathway (PPP) to reduce reactive oxygen species (ROS). In vitro experiments were performed using striatal neurons and cortical or striatal astroglia prepared from Sprague-Dawley rats or C57BL/6 mice. The rates of glucose phosphorylation in astroglia were evaluated using the [ 14 C]deoxyglucose method. PPP activity was measured using [1- 14 C]glucose and [6- 14 C]glucose after acute (60 min) or chronic (15 hr) exposure to dopamine. ROS production was measured using 2′,7′-dichlorodihydrofluorescein diacetate. The involvement of the Kelch-like ECH-associated protein 1 (Keap1) or nuclear factor-erythroid-2-related factor 2 (Nrf2) system was evaluated using Nrf2 gene knockout mice, immunohistochemistry, and quantitative reverse transcription polymerase chain reaction analysis for heme oxygenase-1. Acute exposure to dopamine elicited increases in astroglial glucose consumption with lactate release. PPP activity in astroglia was robustly enhanced independently of Na + -dependent monoamine transporters. In contrast, chronic exposure to dopamine induced moderate increases in PPP activity via the Keap1/Nrf2 system. ROS production from dopamine increased gradually over 12 hr. Dopamine induced neuronal cell damage that was prevented by coculturing with astroglia but not with Nrf2-deficient astroglia. Dopamine-enhanced astroglial PPP activity in both acute and chronic manners may possibly reduce neuronal oxidative stress.
