Abstract: Neuromyelitis optica (NMO) and myelin oligodendrocyte glycoprotein (MOG) antibody-related disease (MOG disease) are inflammatory demyelinating diseases of the central nervous system (CNS). The disruption of the blood-brain barrier (BBB) is considered a key step in the pathogenesis of NMO and MOG disease. Although a previous report indicated that circulating immunoglobulin G (IgG) from NMO patients disrupts the BBB, the effect of IgG from patients with MOG disease has not been elucidated. In addition, it has been reported that some disease-modifying drugs for multiple sclerosis are harmful to NMO by an unknown mechanism. This study aimed to examine the effects of IgG from patients with NMO or MOG disease on BBB integrity. We also examined the effects of disease-modifying drugs (fingolimod [FTY720] and dimethyl fumarate [DMF]) on IgG-treated brain capillary endothelial cells. We used in vitro BBB models constructed with rat brain capillary endothelial cells (RBECs) to examine the effects on BBB function. The integrity of the RBECs was assessed by measuring transendothelial resistance (TEER) and cell viability. NMO or MOG-IgG treatment decreased TEER and cell viability in the endothelial monolayer model. Although FTY720 and DMF did not affect barrier function or cell viability under normal conditions, disease IgG-induced barrier dysfunctions were worsened by the presence of FTY720. These data indicate that circulating IgG in patients with NMO or MOG disease worsens BBB function. Furthermore, in patients with NMO or MOG disease treated with FTY720, changes in the integrity of the BBB were found to exacerbate the disease.

Abstract: ObjectiveTo evaluate whether eculizumab helps patients with anti–acetylcholine receptor–positive (AChR+) refractory generalized myasthenia gravis (gMG) achieve the Myasthenia Gravis Foundation of America (MGFA) post-intervention status of minimal manifestations (MM), we assessed patients' status throughout REGAIN (Safety and Efficacy of Eculizumab in AChR+ Refractory Generalized Myasthenia Gravis) and its open-label extension.MethodsPatients who completed the REGAIN randomized controlled trial and continued into the open-label extension were included in this tertiary endpoint analysis. Patients were assessed for the MGFA post-intervention status of improved, unchanged, worse, MM, and pharmacologic remission at defined time points during REGAIN and through week 130 of the open-label study.ResultsA total of 117 patients completed REGAIN and continued into the open-label study (eculizumab/eculizumab: 56; placebo/eculizumab: 61). At week 26 of REGAIN, more eculizumab-treated patients than placebo-treated patients achieved a status of improved (60.7% vs 41.7%) or MM (25.0% vs 13.3%; common OR: 2.3; 95% CI: 1.1–4.5). After 130 weeks of eculizumab treatment, 88.0% of patients achieved improved status and 57.3% of patients achieved MM status. The safety profile of eculizumab was consistent with its known profile and no new safety signals were detected.ConclusionEculizumab led to rapid and sustained achievement of MM in patients with AChR+ refractory gMG. These findings support the use of eculizumab in this previously difficult-to-treat patient population.ClinicalTrials.gov IdentifierREGAIN, NCT01997229; REGAIN open-label extension, NCT02301624.Classification of EvidenceThis study provides Class II evidence that, after 26 weeks of eculizumab treatment, 25.0% of adults with AChR+ refractory gMG achieved MM, compared with 13.3% who received placebo.

Abstract: A 25-year-old woman was admitted to our hospital due to tonic convulsion with severe headache after having experienced symptoms of nausea and vomiting for a month. Brain magnetic resonance imaging showed extensive symmetrical lesions in the cortical and subcortical areas of parieto-occipital lobes and basal ganglia, consistent with typical characteristics of posterior reversible encephalopathy syndrome (PRES). Furthermore, some residual lesions in the left side of dorsal medulla oblongata and central area of the cervical spinal cord along with the presence of serum anti-aquaporin-4 antibody yielded the diagnosis of neuromyelitis optica spectrum disorder (NMOSD). We herein discuss the mechanism by which PRES may occur together with NMOSD., Internal medicine, 59(15), pp.1887-1890; 2020

Abstract: Background and ObjectivesParaneoplastic cerebellar degeneration (PCD) is characterized by a widespread loss of Purkinje cells (PCs) and may be associated with autoantibodies against intracellular antigens such as Yo or cell surface neuronal antigens such as the P/Q-type voltage-gated calcium channel (P/Q-VGCC). Although the intracellular location of the target antigen in anti–Yo-PCD supports a T cell–mediated pathology, the immune mechanisms in anti–P/Q-VGCC-PCD remain unclear. In this study, we compare neuropathologic characteristics of PCD with anti–P/Q-VGCC and anti-Yo autoantibodies in an archival autopsy cohort.MethodsWe performed neuropathology, immunohistochemistry, and multiplex immunofluorescence on formalin-fixed and paraffin-embedded brain tissue of 1 anti–P/Q-VGCC, 2 anti–Yo-PCD autopsy cases and controls.ResultsAnti–Yo-PCD revealed a diffuse and widespread PC loss together with microglial nodules with pSTAT1+ and CD8+granzymeB+ T cells and neuronal upregulation of major histocompatibility complex (MHC) Class I molecules. Some neurons showed a cytoplasmic immunoglobulin G (IgG) staining. In contrast, PC loss in anti–P/Q-VGCC-PCD was focal and predominantly affected the upper vermis, whereas caudal regions and lateral hemispheres were spared. Inflammation was characterized by scattered CD8+ T cells, single CD20+/CD79a+ B/plasma cells, and an IgG staining of the neuropil in the molecular layer of the cerebellar cortex and neuronal cytoplasms. No complement deposition or MHC-I upregulation was detected. Moreover, synaptophysin was reduced, and neuronal P/Q-VGCC was downregulated. In affected areas, axonal spheroids and the accumulation of amyloid precursor protein and glucose-regulated protein 78 in PCs indicate endoplasmatic reticulum stress and impairment of axonal transport. In both PCD types, calbindin expression was reduced or lost in the remaining PCs.DiscussionAnti–Yo-PCD showed characteristic features of a T cell–mediated pathology, whereas this was not observed in 1 case of anti–P/Q-VGCC-PCD. Our findings support a pathogenic role of anti–P/Q-VGCC autoantibodies in causing neuronal dysfunction, probably due to altered synaptic transmission resulting in calcium dysregulation and subsequent PC death. Because disease progression may lead to irreversible PC loss, anti–P/Q-VGCC-PCD patients could benefit from early oncologic and immunologic therapies.

Abstract: This study aimed to evaluate the diagnostic usefulness of motor end-plate (MEP) analysis along with clustered acetylcholine receptor (AChR) antibody (Ab) assays in patients with myasthenia-like symptoms but negative routine AChR and muscle-specific kinase (MuSK) Ab tests. MEP analysis of muscle biopsies of the biceps brachii was performed in 20 patients to try to differentiate between those with or without immune-mediated myasthenia gravis (MG). Using a quantitative method, complement C3 deposition and AChR densities in MEPs were examined. Independently, cell-based assays were used to detect serum clustered-AChR Abs. Only five of 20 patients had complement deposition at MEPs; four of these patients had reduced AChR densities similar to those in patients with typical AChR Ab positive MG, and distinct from those in the remaining 15 patients. Two of the four serum samples from these patients had clustered-AChR Abs. All complement-positive patients were considered as having immune-mediated MG and improved with appropriate treatments; although one patient presented with MG 3 years later, the remaining patients had other diagnoses during over 10 years of follow-up. These results suggest the usefulness of MEP analysis of muscle biopsies in diagnosing immune-mediated MG in seronegative patients with myasthenia-like symptoms but, due to the invasiveness of the muscle biopsy procedure, clustered AChR Abs should, if possible, be tested first.

Abstract: We herein report two P/Q-type voltage-gated calcium channel (VGCC) antibody-positive Lambert-Eaton myasthenic syndrome (LEMS) patients who responded dramatically to cholinesterase inhibitors. Patient 1, a 76-year-old man, had small-cell lung cancer and developed LEMS during chemotherapy. When symptomatic treatment was started with pyridostigmine, gait disturbance was ameliorated, and his modified Rankin scale decreased from 4 points to 3 points. Patient 2, a 68-year-old man, had cancer-free LEMS. Distigmine bromide was very effective and ameliorated not only his gait disturbance but also autonomic symptoms, and his modified Rankin scale decreased from 2 points to 1 point. Cholinesterase inhibitors alone may be effective in a small portion of LEMS patients.

Abstract: Lambert-Eaton myasthenic syndrome (LEMS) is an autoimmune disease of the neuromuscular junction caused by autoantibodies binding to P/Q-type voltage-gated calcium channels. Breakdown of the blood–brain barrier and diffusion of cerebellar granule/Purkinje cell-reactive autoantibodies into the CNS are critical for the pathogenesis of paraneoplastic cerebellar degeneration (PCD) with Lambert-Eaton myasthenic syndrome. We recently found evidence that glucose-regulated protein 78 (GRP78) autoantibodies in the plasma of patients with neuromyelitis optica promote the CNS access of AQP4 autoantibodies. In the present study, we investigated whether the GRP78 autoantibodies in PCD-LEMS IgG boost the brain uptake of cerebellar cell-reactive antibodies across the blood–brain barrier and facilitate cerebellar dysfunction. We first evaluated the effects of purified IgG from PCD-LEMS or PCD patients on the blood–brain barrier function in human brain microvascular endothelial cells using a high content imaging system with nuclear factor κB p65 and intracellular adhesion molecule 1 (ICAM1) immunostaining. Next, we identified GRP78 autoantibodies causing blood–brain barrier permeability in PCD-LEMS IgG by co-immunoprecipitation and the living cell-based antibody binding assays. Exposure of brain microvascular endothelial cells to IgG from PCD-LEMS patients induced nuclear factor κB p65 nuclear translocation, ICAM1 upregulation, reduced claudin-5 expression, increased permeability and increased autocrine IL-1β and IL-8 secretion; the IgG from patients with Lambert-Eaton myasthenic syndrome did not have these effects. We detected GRP78 autoantibodies in the IgG of LEMS-PCD (83.3%, n = 18), but observed fewer in patients with LEMS (6.6%, n = 15) and none were observed in the control subjects (n = 8). The depletion of GRP78 autoantibodies reduced the biological effect of LEMS-PCD IgG on brain microvascular endothelial cells. These findings suggest that GRP78 autoantibodies play a role beyond neuromyelitis optica and that they have direct implications in the phenotypic differences between PCD-LEMS and LEMS.

Abstract: Purpose: The aim of this study was to identify whether diastolic dysfunction predicts death at 90 days after acute ischemic stroke.Methods: We retrospectively analyzed patients with ischemic stroke. All patients underwent transthoracic echocardiography to evaluate systolic function and diastolic function by means of assessing ejection fraction and septal E/e’.We evaluated the initial National Institute of Health Stroke Scale (NIHSS) score,arterial occlusion, and laboratory data. We used multivariate regression models to identify independent predictors of 90-day mortality. Results: Among 1208 patients, the overall 90-day mortality rate was 8%. In multivariate logistic regression analysis, a higher initial NIHSS score,plasma D-dimer level and E/e’ and occlusion of internal carotid artery or basilar artery were independent predictors of 90-day mortality.The DONE score derived from these valuables showed good discrimination with area under the curve (AUC) value of 0.82 (95% confidence interval [CI],0.78?0.87) to predict 90-day mortality. The DONE score also predicted poor outcome (modified Rankin scale score, 4?6) at 90 days (AUC, 0.82;95% CI 0.80?0.85). Conclusions: Higher E/e’ indicating diastolic dysfunction,may be associated with 90-day mortality in patients with acute ischemic stroke. The DONE score could readily predict poor outcome after acute ischemic stroke., Journal of the Neurological Sciences, 398, pp.157-162; 2019

Abstract: Background: It is unclear whether biomarkers of cardiac dysfunction are associated with cryptogenic stroke (CS). Methods: We retrospectively evaluated consecutive ischemic stroke patients. Patients underwent transthoracic echocardiography to evaluate left atrial diameter and the peak transmitral filling velocity/mean mitral annular velocity during early diastole (E/e’). Patent foramen ovale (PFO) and left atrial appendage flow velocity were evaluated by transesophageal echocardiography. We compared clinical characteristics and biomarkers of cardiac dysfunction (brain natriuretic peptide [BNP], left atrial diameter, E/e’, and left atrial appendage flow velocity) between CS or CS without large PFO and other causative stroke subtypes. Results: Among 1,514 patients with ischemic stroke, 264 patients were classified as having CS. Of these, transesophageal echocardiography revealed 27/158 (17%) large PFOs. In comparison, for the noncardioembolic stroke group, which consisted of large artery and small vessel subtypes, patients with CS without large PFO had higher log10 BNP (adjusted OR 2.70; 95% CI 1.92–3.78; p < 0.001), higher log10 E/e’ (3.41; 1.21–13.15; p = 0.019), and lower left atrial appendage flow velocity (0.98; 0.97–1.00; p = 0.031). Left atrial diameter was similar for noncardioembolic stroke and CS without large PFO (p = 0.380). Cutoff values of BNP, E/e’, and left atrial appendage flow velocity capable of distinguishing CS without large PFO from noncardioembolic stroke were 65.0 pg/mL (sensitivity 55.3%; specificity 70.9%), 13.0 (45.5%; 68.0%), and 46.0 cm/s (37.1%; 87.5%), respectively. Conclusion: Patients with CS without large PFO could have biomarkers of cardiac dysfunction.

Abstract: Geobacillus kaustophilus is a thermophilic bacterium that grows at temperatures ranging between 42 and 74 °C. Here, we modified this organism to produce the thermolabile protein (PyrFA) or its thermostable variant (PyrFV) and analyzed the transcriptome and growth efficiency profiles of the resultant strains. In the producer of PyrFA, the transcriptome profile was changed to facilitate ATP synthesis from NADH without pooling reduced quinones. This change implies that PyrFA production at elevated temperatures places an energy burden on cells potentially to maintain protein homeostasis. This was consistent with the observation that the PyrFA producer grew slower than the PyrFV producer at > 45 °C and had a lower cellular fitness. Similar growth profiles were also observed in the PyrFA and PyrFV producers derived from another thermophile (Geobacillus thermodenitrificans) but not in those from Escherichia coli at 30 °C. Thus, we suggest that the production of thermolabile proteins impairs host survival at higher temperatures; therefore, thermophiles are under evolutionary selection for thermostable proteins regardless of whether their functions are associated with survival advantages. This hypothesis provides new insights into evolutionary protein selection in thermophiles and suggests an engineering approach to select thermostable protein variants generated via random gene mutagenesis.

Abstract: Neuromyelitis optica (NMO) and myelin oligodendrocyte glycoprotein (MOG) antibody-related disease (MOG disease) are inflammatory demyelinating diseases of the central nervous system (CNS). The disruption of the blood-brain barrier (BBB) is considered a key step in the pathogenesis of NMO and MOG disease. Although a previous report indicated that circulating immunoglobulin G (IgG) from NMO patients disrupts the BBB, the effect of IgG from patients with MOG disease has not been elucidated. In addition, it has been reported that some disease-modifying drugs for multiple sclerosis are harmful to NMO by an unknown mechanism. This study aimed to examine the effects of IgG from patients with NMO or MOG disease on BBB integrity. We also examined the effects of disease-modifying drugs (fingolimod [FTY720] and dimethyl fumarate [DMF]) on IgG-treated brain capillary endothelial cells. We used in vitro BBB models constructed with rat brain capillary endothelial cells (RBECs) to examine the effects on BBB function. The integrity of the RBECs was assessed by measuring transendothelial resistance (TEER) and cell viability. NMO or MOG-IgG treatment decreased TEER and cell viability in the endothelial monolayer model. Although FTY720 and DMF did not affect barrier function or cell viability under normal conditions, disease IgG-induced barrier dysfunctions were worsened by the presence of FTY720. These data indicate that circulating IgG in patients with NMO or MOG disease worsens BBB function. Furthermore, in patients with NMO or MOG disease treated with FTY720, changes in the integrity of the BBB were found to exacerbate the disease.

Abstract: Neuronal intranuclear inclusion disease (NIID) is a slowly progressive neurodegenerative disease. Some patients with NIID occasionally present with acute symptoms. However, its mechanism remains unclear. We report a patient with NIID who presented with a stroke-like episode. Arterial spin labeling magnetic resonance imaging revealed hypoperfusion in the focal cerebral region at the onset while no apparent arterial occlusion was observed. The abnormal perfusion area was normalized 6 days after admission. Therefore, the perfusion abnormality was likely the main cause of acute neurologic deficits in NIID. NIID should be considered in the differential diagnosis of stroke mimics., Cerebral Circulation - Cognition and Behavior, 3, art.no.100127; 2022

Abstract: Although acute retinal necrosis (ARN) and optic neuritis following herpes encephalitis are known causes of acute visual impairment associated with herpes simplex virus (HSV) infection, there have been no reports of parainfectious optic neuritis associated with genital HSV type 2 (HSV-2) infection. A young Japanese woman developed unilateral optic neuritis 7 days after the onset of genital HSV-2 infection. Ophthalmologic examination revealed no findings suggestive of ARN and both multiple sclerosis and neuromyelitis optica were ruled out by the brain images and serum antibody testing. An oral steroid therapy improved her symptoms. Here, we describe the first case of parainfectious optic neuritis associated with genital HSV-2 infection.

Abstract: The terminal complement inhibitor eculizumab was shown to improve myasthenia gravis-related symptoms in the 26-week, phase 3, randomized, double-blind, placebo-controlled REGAIN study (NCT01997229). In this 52-week sub-analysis of the open-label extension of REGAIN (NCT02301624), eculizumab's efficacy and safety were assessed in 11 Japanese and 88 Caucasian patients with anti-acetylcholine receptor antibody-positive refractory generalized myasthenia gravis. For patients who had received placebo during REGAIN, treatment with open-label eculizumab resulted in generally similar outcomes in the Japanese and Caucasian populations. Rapid improvements were maintained for 52 weeks, assessed by change in score from open-label extension baseline to week 52 (mean [standard error]) using the following scales (in Japanese and Caucasian patients, respectively): Myasthenia Gravis Activities of Daily Living (-2.4 [1.34] and - 3.3 [0.65]); Quantitative Myasthenia Gravis (-2.9 [1.98] and - 4.3 [0.79]); Myasthenia Gravis Composite (-4.5 [2.63] and - 4.9 [1.19]); and Myasthenia Gravis Quality of Life 15-item questionnaire (-8.6 [5.68] and - 6.5 [1.93]). Overall, the safety of eculizumab was consistent with its known safety profile. In this interim sub-analysis, the efficacy and safety of eculizumab in Japanese and Caucasian patients were generally similar, and consistent with the overall REGAIN population. ispartof: JOURNAL OF THE NEUROLOGICAL SCIENCES vol:407 ispartof: location:Netherlands status: published

Abstract: VCP mutations were first associated with inclusion body myopathy with Paget’s disease of bone and frontotemporal dementia (IBMPFD) but was later associated with amyotrophic lateral sclerosis and Charcot–Marie–Tooth disease. Now, a new name, “multisystem proteinopathy (MSP)”, is proposed for this condition. VCP encodes valosin-containing protein, which is involved in protein degradation in the ubiquitin proteasome system. We report here two MSP patients with two novel heterozygous missense variants in VCP: c.259G>T (p.Val87Phe) and c.376A>G (p.Ile126Val).

Abstract: Background Complement is likely to have a role in refractory generalised myasthenia gravis, but no approved therapies specifically target this system. Results from a phase 2 study suggested that eculizumab, a terminal complement inhibitor, produced clinically meaningful improvements in patients with anti-acetylcholine receptor antibody-positive refractory generalised myasthenia gravis. We further assessed the efficacy and safety of eculizumab in this patient population in a phase 3 trial. Methods We did a phase 3, randomised, double-blind, placebo-controlled, multicentre study (REGAIN) in 76 hospitals and specialised clinics in 17 countries across North America, Latin America, Europe, and Asia. Eligible patients were aged at least 18 years, with a Myasthenia Gravis-Activities of Daily Living (MG-ADL) score of 6 or more, Myasthenia Gravis Foundation of America (MGFA) class II-IV disease, vaccination against Neisseria meningitides, and previous treatment with at least two immunosuppressive therapies or one immunosuppressive therapy and chronic intravenous immunoglobulin or plasma exchange for 12 months without symptom control. Patients with a history of thymoma or thymic neoplasms, thymectomy within 12 months before screening, or use of intravenous immunoglobulin or plasma exchange within 4 weeks before randomisation, or rituximab within 6 months before screening, were excluded. We randomly assigned participants (1:1) to either intravenous eculizumab or intravenous matched placebo for 26 weeks. Dosing for eculizumab was 900 mg on day 1 and at weeks 1, 2, and 3; 1200 mg at week 4; and 1200 mg given every second week thereafter as maintenance dosing. Randomisation was done centrally with an interactive voice or web-response system with patients stratified to one of four groups based on MGFA disease classification. Where possible, patients were maintained on existing myasthenia gravis therapies and rescue medication was allowed at the study physician's discretion. Patients, investigators, staff, and outcome assessors were masked to treatment assignment. The primary efficacy endpoint was the change from baseline to week 26 in MG-ADL total score measured by worst-rank ANCOVA. The efficacy population set was defined as all patients randomly assigned to treatment groups who received at least one dose of study drug, had a valid baseline MG-ADL assessment, and at least one post-baseline MG-ADL assessment. The safety analyses included all randomly assigned patients who received eculizumab or placebo. This trial is registered with ClinicalTrials.gov, number NCT01997229. Findings Between April 30, 2014, and Feb 19, 2016, we randomly assigned and treated 125 patients, 62 with eculizumab and 63 with placebo. The primary analysis showed no significant difference between eculizumab and placebo (least-squares mean rank 56·6 [SEM 4·5] vs 68·3 [4·5]; rank-based treatment difference -11·7, 95% CI -24·3 to 0·96; p=0·0698). No deaths or cases of meningococcal infection occurred during the study. The most common adverse events in both groups were headache and upper respiratory tract infection (ten [16%] for both events in the eculizumab group and 12 [19%] for both in the placebo group). Myasthenia gravis exacerbations were reported by six (10%) patients in the eculizumab group and 15 (24%) in the placebo group. Six (10%) patients in the eculizumab group and 12 (19%) in the placebo group required rescue therapy. Interpretation The change in the MG-ADL score was not statistically significant between eculizumab and placebo, as measured by the worst-rank analysis. Eculizumab was well tolerated. The use of a worst-rank analytical approach proved to be an important limitation of this study since the secondary and sensitivity analyses results were inconsistent with the primary endpoint result; further research into the role of complement is needed.

Abstract: Natural circulation is a key technology for developing the molten core cooling system without an external power source from the lessons of the severe accident at Fukushima-Daiichi Nuclear Power Station. This study is devoted to quantify the void fraction which is an important parameter for the driving force of natural circulation flow, and to evaluate the effect of the void fraction correlation on the prediction accuracy of the natural circulation flow rate. Test was conducted at atmospheric pressure and room temperature, using the upward air–water two phase flow. Vertical tubes with an inner diameter of 36 and 25 mm were used as the test section. The void fraction was measured by three different methods: quick-closing valve method, pressure drop method, and conductive void-probe method. The following conclusions are obtained from this study: (1) The data of the natural circulation flow rate, void fraction and pressure drop for the upward air–water two phase flow at atmospheric pressure and room temperature were obtained to develop and verify the new model. (2) By improving the void correlation, it was found that the prediction accuracy of the natural circulation flow rate could be improved by about 10% to 5%, that is, the prediction error can be halved in the range of this study. (3) The natural circulation flow rate for 25 mm test section was saturated with increasing the air flow rate at higher air flow condition. The model cannot predict this tendency. From the point of design of the actual molten core cooling system, the model improvements in this region are necessary in the future.

Abstract: Background We report a case of a 64-year-old Japanese man who was diagnosed with definite multifocal motor neuropathy and successfully treated with administration of intravenous immunoglobulin (IVIg) spread over two separate weeks. Case presentation After IVIg administration (30 g/day, five consecutive days), motor function was improved, but it was not possible to maintain the muscle strength just a few months after treatment. Although plasma exchange and cyclosporine were combined, the patient developed muscle weakness just 2 weeks after initial IVIg treatment. His grip strength decreased to 0 kg, proximal upper-limb muscle strength reduced to 2/5 according to manual muscle testing, and muscle weakness developed in the proximal lower limb muscle. We modified IVIg administration protocol from five consecutive days to two separate weeks: 3 days in the first week and 2 days in the third week without changing the total dose per month. After initiation of divided IVIg protocol, muscle weakness dramatically improved, and muscle power could be kept normal. Corrected optical density value of immunoglobulin M antibodies against GM1 elevated in the all clinical course did not correlate with muscle strength improvement. Serum immunoglobulin G levels became stable in ≥2000 mg/dL, and were associated with muscle strength improvement. Conclusion Administration of IVIg over two separate weeks might be a treatment option in intractable patients with multifocal motor neuropathy.

Abstract: A 72-year-old Japanese man developed progressive disturbance in ambulation with flexion contractures 5years before this admission. At 49 years of age, he was diagnosed with hypopituitarism after an operation for a Rathke's cleft. On admission, he could not fully extend his knees and hips because of painful muscle stiffness of the lower extremities. Initially, we suspected Stiff-person syndrome and initiated diazepam, which had no effect. Serum anti-glutamic acid decarboxylase antibody was negative. Next, we suspected flexion contractures associated with hypopituitarism. Endocrine evaluation revealed that ACTH, cortisol, and other hormone levels were lower than those reported in the previous evaluation. We treated the patient with hydrocortisone and his symptoms dramatically improved. It is rare for patients with hypopituitarism to have flexion contracture. This case suggests that we should consider hypopituitararism in the setting of flexion contractures. (Received October 18, 2018; Accepted March 26, 2019; Published June 1, 2019).

Abstract: Background: It is unclear whether biomarkers of cardiac dysfunction are associated with embolic stroke of undetermined source (ESUS), while large patent foramen ovale (PFO) could relate to it. Method: We retrospectively review patients with ischemic stroke who underwent transesophageal echocardiography (TEE) from April 2012, to April 2018. The peak transmitral filling velocity/early diastolic mitral annular tissue velocity (E/e’) on transthoracic echocardiography was used to estimate diastolic dysfunction. PFO and left atrial appendage (LAA) flow velocity were evaluated by TEE. We compared risk factors, clinical characteristics and biomarkers of cardiac dysfunction (brain natriuretic peptide [BNP], left atrial diameter, E/e’, the presence of systolic dysfunction [EF Results: Among 294 patients with ESUS, 163 patients underwent TEE (55%). Of these, 24 patients (15%) had large PFO. Compared with ESUS patients with large PFO, those without large PFO had higher BNP (adjusted odds ratio 1.02, 95% confidence interval; 1.00-1.03, p=0.002) and higher E/e’ (1.25, 1.06-1.48; p=0.003). Left atrial diameter, EF 50 pg/ml and E/e’ > 12, which were median values, had worse clinical outcome compared to patients who have less cardiac biomarkers and patients with large PFO. (p=0.005) Conclusion: ESUS Patients without large PFO often have biomarkers of cardiac dysfunction. The clinic outcome of ESUS patients without large PFO who have biomarkers of cardiac dysfunction could be worse than that of ESUS patients with large PFO.

Abstract: To investigate whether aquaporins (AQPs) are involved in salivary gland dysfunction in patients with neuromyelitis optica (NMO) complicated with Sjögren's syndrome (SS).Eight primary SS (pSS) patients, four NMO spectrum disorder (NMOsd) patients complicated with SS (NMOsd-SS), and three control subjects were enrolled. Immunohistochemistry of labial salivary glands (LSGs) was performed to determine the expressions of AQP4, AQP5, and tumor necrosis factor-alpha (TNF-α). In vitro expression of AQP5 was examined by Western blotting in cultured primary salivary gland epithelial cells (SGECs).No expression of AQP4 was shown in all LSGs. AQP5 was clearly expressed in the all acini, but the predominant localization of AQP5 in the apical side was diminished in the patients with pSS or NMOsd-SS compared with the controls and tended to be even lower in NMOsd-SS than pSS. The abnormal localization of AQP5 was associated with poor saliva secretion. No difference was found in TNF-α expression in the LSGs between patients with pSS and NMOsd-SS. AQP5 expression of SGECs in vitro was not changed by TNF-α or interleukin-10.Our results suggest that AQP5 but not AQP4 contributes to salivary secretion in patients with SS including those with NMO complicated with SS.

Abstract: IgG4-related disease is a systemic disease characterized by lesions with IgG4 positive plasma cell infiltration in the involved organs and a raised serum IgG4 level. We report a patient of 70-year-old male presented orbital inflammation of IgG4-related disease. The patient developed right eye pain, double vision, and reduced eye sight. MRI image revealed mild right ocular proptosis and swelling of right carvenous sinus, bilateral intraorbital extraocular muscles and right optic nerve. Right optic nerve showed ring-like enhancement. IgG4-related disease was suspected with increased serum IgG4 level of 355 mg/dl, mediastinal lymphadenopathy and prostate enlargement. Transbronchial lung biopsy and prostate needle biopsy were administered with negative results. The eye related symptoms resolved with time, but serum IgG4 continuously increased. IgG4-related disease was diagnosed by nasal mucosa biopsy, which showed IgG4 positive plasma cells within the inflammatory infiltrate. This report emphasizes the usefulness of nasal mucosa biopsy for the diagnosis of IgG4 related disease with lesions difficult to approach.

Abstract: Myasthenic crisis (MC) is a life-threatening condition in patients with myasthenia gravis (MG), for which thymectomy is known to be a predisposing factor. There are many preoperative factors that have been suggested to increase the occurrence of post-operative myasthenic crisis (POMC), but none have been unanimously concluded as definite risk factors.We performed meta-analyses to assess preoperative risk factors for the occurrence of POMC in eligible case-control studies.A total of 10 articles were systematically reviewed and meta-analyses identified preoperative bulbar symptoms, a history of MC, and disease severity (p .0001), as well as decreased vital capacity (p = .002), as risk factors for POMC. Among the identified risks, the presence of preoperative bulbar symptoms showed the least heterogeneity and was suggested to be the most reliable preoperative risks of POMC.Presence of preoperative bulbar symptoms is an easily discernable risk factor for the occurrence of POMC. A history of preoperative MC will further increase the risk of POMC. Patients with these risks require extra caution and should be closely monitored for POMC upon thymectomy.

Abstract: A 17-year-old male underwent a second bone marrow transplantation using a 6/8 allele HLA-matched unrelated donor. On day 100 after transplantation, steroid treatment for chronic graft-versus-host disease (GVHD) was started. On day 766, the patient experienced general fatigue, followed by double vision, ptosis, and dysphagia on day 810. Based on the positivity of the acetylcholine receptor antibody and a waning electromyography pattern, he was diagnosed with GVHD-related myasthenia gravis (MG). On day 861, we initiated plasmapheresis (PE), followed by the administration of intravenous immunoglobulin (IVIg) ; this treatment attenuated the bulbar symptoms of MG. Although the steroid treatment was continued, we restarted the administration of tacrolimus. On day 2,739 after transplantation, we stopped the steroid treatment, and the patient remained in remission for MG following the cessation of the steroid treatment on day 2,897. This case suggests that PE followed by IVIg could be an effective therapeutic alternative for MG associated with GVHD.

Abstract: BACKGROUND AND PURPOSE: Rupture of the plaque fibrous cap and subsequent thrombosis are the major causes of stroke. This study evaluated morphologic features of plaque rupture in the carotid artery by using optical coherence tomography in vivo. MATERIALS AND METHODS: Thirty-six carotid plaques with high-grade stenosis were prospectively imaged by optical coherence tomography. “Plaque rupture” was defined as a plaque containing a cavity that had overlying residual fibrous caps. The fibrous cap thickness was measured at its thinnest part for both ruptured and nonruptured plaques. The distance between the minimum fibrous cap thickness site and the bifurcation point was also measured. Optical coherence tomography identified 24 ruptured and 12 nonruptured plaques. RESULTS: Multiple ruptures were observed in 9 (38%) patients: Six patients had 2 ruptures in the same plaque, 2 patients had 3 ruptures in the same plaque, and 1 patient had 5 ruptures in the same plaque. Most (84%) of the fibrous cap disruptions were identified at the plaque shoulder and near the bifurcation point (within a 4.2-mm distance). The median thinnest cap thickness was 80 μm (interquartile range, 70–100 μm), and 95% of ruptured plaques had fibrous caps of

Abstract: The aim of this study was to show the clinical and pathological characteristics of anti-centromere-antibody (ACA)-seropositive Sjögren's syndrome (SS) in two anti-human T-cell leukemia virus type I (HTLV-I)-seropositive patients.One patient was an HTLV-I carrier whereas the other was diagnosed with HTLV-I-associated myelopathy (HAM). Background data including serum HTLV-I titers, viral loads, and cytokine profiles were recorded. Azocarmine with aniline blue (Azan)-Mallory staining and immunohistochemistry of the labial salivary glands (LSGs) and a muscle biopsy specimen from the HAM patient were performed.Serum transforming growth factor beta (TGF-β), tumor necrosis factor alpha (TNF-α), and HTLV-I viral load were high in the HAM-SS patient compared with the HTLV-I carrier. Fibrous change in LSG was prominent in the HAM-SS patient. Although TGF-β expression was similar in the two patients, expression of HTLV-I-related proteins including p12, p28, group-specific antigen (GAG), and nuclear factor kappa-B (NF-κB) in the LSG were dominantly detected in the HAM-SS patient. Frequency of TGF-β staining in HTLV-I-seropositive SS patients without ACA, HTLV-I-seronegative SS patients with ACA, and HTLV-I-seronegative SS patients without ACA was lower than that of the previous two patients.A high HTLV-I viral load in situ is supposed to promote the production of cytokines, especially TGF-β, resulting in the fibrous change of LSG in ACA-seropositive SS patients.

Abstract: SUMMARY A novel method for automatically creating an optimum direction-of-arrival (DOA) estimation algorithm for a given radio environment using a genetic algorithm (GA) is proposed. DOA estimation algorithms are generally described by parameters and operators. The performance of a DOA estimation algorithm is evaluated using root mean square error (RMSE) through computer simulations. A GA searches for the combination of parameters and operators that gives the lowest RMSE. Because a GA can treat only bit strings, Polish notation is used to convert bit strings into a DOA estimation algorithm. A computer simulation showed that the proposed method can create a new angle spectrum function. The created

Abstract: We herein investigated the clinical features of three patients with anti-muscle-specific tyrosine kinase (MuSK) antibody-positive myasthenia gravis (MG), which was initially difficult to distinguish from amyotrophic lateral sclerosis (ALS). The patients exhibited dropped head syndrome or dysphagia as initial symptoms. Although their clinical findings were compatible with the revised El Escorial Criteria for ALS, their progression appeared to be more rapid than that of ALS. Both the edrophonium and repetitive nerve stimulation tests yielded negative results, and diurnal fluctuation was not confirmed. The patients were ultimately diagnosed with anti-MuSK antibody-positive MG. We therefore recommend the measurement of anti-MuSK antibodies when encountering such cases.

Abstract: We measured serum uric acid levels in Yusho sufferers annually from 2007 to 2012 in Nagasaki prefecture. We observed an increased rate of serum uric acid levels in 38.2% of the male and 5.5% of the female sufferers. There was no relation among serum uric acid value, Body Mass Index, liver function, blood polychlorinated biphenyls and hypersensitive C reactive protein. We conclude that it is unclear if blood polychlorinated biphenyls may play a role in the increase of serum uric acid levels in Yusho sufferers.

Abstract: Polymyositis (PM) is an inflammatory muscle disease characterized by chronic inflammation in skeletal muscle. Although most patients with PM respond to corticosteroids, some cases show an unsatisfactory response and other therapeutic options must be considered. Furthermore, glucocorticosteroid (GC) toxicity leads to a significant disability known as steroid myopathy, particularly in elderly patients. Here we report two patients with refractory PM. Combined treatment with high-dose GCs, tacrolimus, and intravenous immunoglobulin resulted in beneficial effects against myositis. However, muscle weakness and the disability progressed due to steroid myopathy, and subsequent oral intake became impossible because of swallowing disturbance in these two patients. Nutritional intervention, including branched-chain amino acids (BCAAs) and rehabilitation, was undertaken in addition to treatment against myositis. These treatments finally improved the muscle weakness and activities of daily living, and the two patients were discharged after recovery. The high-dose GC treatment caused elevation of serum levels of amino acids, including BCAAs, but these amino acids subsequently declined during BCAA replacement therapy. These findings suggest that the catabolic effects of the glucocorticoid treatment impair the balance of amino acids, including BCAAs, within the muscle, leading to steroid myopathy.

Abstract: Objectives: To investigate the differences of clinical features, cerebrospinal fluid (CSF), MRI findings and response to steroid therapies between patients with optic neuritis (ON) who have myelin oligodendrocyte glycoprotein (MOG) antibodies and those who have seronegative ON. Setting: We recruited participants in the department of neurology and ophthalmology in our hospital in Japan. Methods: We retrospectively evaluated the clinical features and response to steroid therapies of patients with ON. Sera from patients were tested for antibodies to MOG and aquaporin-4 (AQP4) with a cell-based assay. Participants: Between April 2009 and March 2014, we enrolled serial 57 patients with ON (27 males, 30 females; age range 16-84 years) who ophthalmologists had diagnosed as having or suspected to have ON with acute visual impairment and declined critical flicker frequency, abnormal findings of brain MRI, optical coherence tomography and fluorescein fundus angiography at their onset or recurrence. We excluded those patients who fulfilled the diagnostic criteria of neuromyelitis optica (NMO)/NMO spectrum disorders (NMOSD), MS McDonald's criteria, and so on. Finally we defined 29 patients with idiopathic ON (14 males, 15 females, age range 16-84 years). Results: 27.6% (8/29) were positive for MOG antibodies and 3.4% (1/29) were positive for AQP4. Among the eight patients with MOG antibodies, five had optic pain (p=0.001) and three had prodromal infection (p=0.179). Three of the eight MOG-positive patients showed significantly high CSF levels of myelin basic protein (p=0.021) and none were positive for oligoclonal band in CSF. On MRIs, seven MOG-positive patients showed high signal intensity on optic nerve, three had a cerebral lesion and one had a spinal cord lesion. Seven of the eight MOG-positive patients had a good response to steroid therapy. Conclusions: Although not proving primary pathogenicity of anti-MOG antibodies, the present results indicate that the measurement of MOG antibodies is useful in diagnosing and treating ON., BMJ Open, 5(4), e007766; 2015
