Objective: This study was undertaken to determine the excess risk of antithrombotic‐related bleeding due to cerebral small vessel disease (SVD) burden. Methods: In this observational, prospective cohort study, patients with cerebrovascular or cardiovascular diseases taking oral antithrombotic agents were enrolled from 52 hospitals across Japan between 2016 and 2019. Baseline multimodal magnetic resonance imaging acquired under prespecified conditions was assessed by a central diagnostic radiology committee to calculate total SVD score. The primary outcome was major bleeding. Secondary outcomes included bleeding at each site and ischemic events. Results: Of the analyzed 5,250 patients (1,736 women; median age = 73 years, 9,933 patient‐years of follow‐up), antiplatelets and anticoagulants were administered at baseline in 3,948 and 1,565, respectively. Median SVD score was 2 (interquartile range = 1–3). Incidence rate of major bleeding was 0.39 (per 100 patinet‐years) in score 0, 0.56 in score 1, 0.91 in score 2, 1.35 in score 3, and 2.24 in score 4 (adjusted hazard ratio [aHR] for score 4 vs 0 = 5.47, 95% confidence interval [CI] = 2.26–13.23), that of intracranial hemorrhage was 0.11, 0.33, 0.58, 0.99, and 1.06, respectively (aHR = 9.29, 95% CI = 1.99–43.35), and that of ischemic event was 1.82, 2.27, 3.04, 3.91, and 4.07, respectively (aHR = 1.76, 95% CI = 1.08–2.86). In addition, extracranial major bleeding (aHR = 3.43, 95% CI = 1.13–10.38) and gastrointestinal bleeding (aHR = 2.54, 95% CI = 1.02–6.35) significantly increased in SVD score 4 compared to score 0. Interpretation: Total SVD score was predictive for intracranial hemorrhage and probably for extracranial bleeding, suggesting the broader clinical relevance of cerebral SVD as a marker for safe implementation of antithrombotic therapy.

Background and ObjectivesIn patients with ischemic stroke (IS) or transient ischemic attack (TIA) and cortical superficial siderosis (cSS), there are few data regarding the risk of future cerebrovascular events and also about the benefits and safety of antithrombotic drugs for secondary prevention. We investigated the associations of cSS and stroke risk in patients with recent IS or TIA.MethodsWe retrospectively analyzed the Microbleeds International Collaborative Network (MICON) database. We selected patients with IS or TIA from cohorts who had MRI-assessed cSS, available data on antithrombotic treatments, recurrent cerebrovascular events (intracranial hemorrhage [ICrH], IS, or any stroke [ICrH or IS]), and mortality. We calculated incidence rates (IRs) and performed univariable and multivariable Cox regression analyses.ResultsOf 12,669 patients (mean age 70.4 ± 12.3 years, 57.3% men), cSS was detected in 273 (2.2%) patients. During a mean follow-up of 24 ± 17 months, IS was more frequent than ICrH in both cSS (IR 57.1 vs 14.6 per 1,000 patient-years) and non-cSS (33.7 vs 6.3 per 1,000 patient-years) groups. Compared with the non-cSS group, cSS was associated with any stroke on multivariable analysis {IR 83 vs 42 per 1,000 patient-years, adjusted hazard ratio [HR] for cSS 1.62 (95% CI: 1.14–2.28;p= 0.006)}. This association was not significant in subgroups of patients treated with antiplatelet drugs (n = 6,554) or with anticoagulants (n = 4,044). Patients with cSS who were treated with both antiplatelet drugs and anticoagulants (n = 1,569) had a higher incidence of ICrH (IR 107.5 vs 4.9 per 1,000 patient-years, adjusted HR 13.26; 95% CI: 2.90–60.63;p= 0.001) and of any stroke (IR 198.8 vs 34.7 per 1,000 patient-years, adjusted HR 5.03; 95% CI: 2.03–12.44;p< 0.001) compared with the non-cSS group.DiscussionPatients with IS or TIA with cSS are at increased risk of stroke (ICrH or IS) during follow-up; the risk of IS exceeds that of ICrH for patients receiving antiplatelet or anticoagulant treatment alone, but the risk of ICrH exceeds that of IS in patients receiving both treatments. The findings suggest that either antiplatelet or anticoagulant treatment alone should not be avoided in patients with cSS, but combined antithrombotic therapy might be hazardous. Our findings need to be confirmed by randomized clinical trials.

Objectives: Cerebral microbleeds are associated with the risks of ischemic stroke and intracranial hemorrhage, causing clinical dilemmas for antithrombotic treatment decisions. We aimed to evaluate the risks of intracranial hemorrhage and ischemic stroke associated with microbleeds in patients with atrial fibrillation treated with vitamin K antagonists, direct oral anticoagulants, antiplatelets, and combination therapy (i.e. concurrent oral anticoagulant and antiplatelet).Methods: We included patients with documented atrial fibrillation from the pooled individual patient data analysis by the Microbleeds International Collaborative Network. Risks of subsequent intracranial hemorrhage and ischemic stroke were compared between patients with and without microbleeds, stratified by antithrombotic use.Results: A total of 7,839 patients were included. The presence of microbleeds was associated with an increased relative risk of intracranial hemorrhage (adjusted hazard ratio [aHR] = 2.74, 95% confidence interval = 1.76-4.26) and ischemic stroke (aHR = 1.29, 95% confidence interval = 1.04-1.59). For the entire cohort, the absolute incidence of ischemic stroke was higher than intracranial hemorrhage regardless of microbleed burden. However, for the subgroup of patients taking combination of anticoagulant and antiplatelet therapy, the absolute risk of intracranial hemorrhage exceeded that of ischemic stroke in those with 2 to 4 microbleeds (25 vs 12 per 1,000 patient-years) and ≥ 11 microbleeds (94 vs 48 per 1,000 patient-years).Interpretation: Patients with atrial fibrillation and high burden of microbleeds receiving combination therapy have a tendency of higher rate of intracranial hemorrhage than ischemic stroke, with potential for net harm. Further studies are needed to help optimize stroke preventive strategies in this high-risk group. ANN NEUROL 2023.

Background: Haploinsufficiency of cytotoxic T‐lymphocyte antigen 4 (CTLA4) is a primary immunodeficiency disease characterized by hypogammaglobulinemia and diverse autoimmune disorders. Although central nervous system lesions have been described in patients with CTLA4 insufficiency, there have been few reports in the field of neurology. Case presentation: A 23‐year‐old man was referred to Saga University Hospital (Saga, Japan) with dizziness and abnormal head magnetic resonance imaging showing hyperintensity in the left cerebellar hemisphere. He was diagnosed with immune thrombocytopenia and hypogammaglobulinemia at age 8 years. He had repeated mild upper respiratory infections. Neurological events had occurred four times, with a long spinal lesion extending over three vertebral segments. High‐dose intravenous methylprednisolone was effective for acute attacks, and low‐dose prednisolone prevented relapses for 7 years. When he reached the age of 37 years, he developed severe diarrhea and immune cytopenia, and lost 6 kg in half a year. It was suspected that the patient had primary immunodeficiency due to his history of recurrent infections, hypogammaglobulinemia and severe diarrhea. Genome sequencing showed a heterozygous CTLA4 variant in exon 2. Abatacept therapy with prednisolone and cyclosporine was effective for diarrhea and autoimmune cytopenia. Conclusions: A patient with CTLA4 variant might develop multiple central nervous system lesions including longitudinally‐extended spinal cord lesions. As there is effective targeted immunotherapy, a complete immunological work‐up is required for early diagnosis when a patient presents with central nervous system lesions and multi‐organ symptoms.

Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive brain stimulation method providing a promising technique for improving cognitive symptoms in treatment-resistant depression (TRD). In the present study, we investigated whether a relationship exists between improvements in frontal lobe dysfunction induced by rTMS and improvement of white matter integrity revealed by diffusion tensor imaging (DTI) in TRD patients receiving rTMS treatment.Methods: A total of 12 patients with TRD were enrolled in a high-frequency (10 Hz) rTMS study (August 2013–January 2019). Frontal lobe function and depressive symptoms were assessed at baseline and at the endpoint of rTMS treatment. Fractional anisotropy (FA), as a measure of white matter integrity obtained from DTI, was investigated using a region-of-interest (ROI) approach.Results: rTMS treatment significantly improved depressive symptom scores and some subscales of frontal lobe dysfunction. Category scores in the Word Fluency Test and scores on part 3 of the Color Stroop Test were improved independently of the improvement of depressive symptoms. In the ROI analysis, none of the FA increases in any region were correlated with improvement of any frontal lobe function (n = 12).Conclusion: Although rTMS resulted in partial improvement of frontal lobe dysfunction as well as white matter integrity, we found no correlation between improved frontal lobe dysfunction and improved white matter integrity in TRD patients.Keywords: repetitive transcranial magnetic stimulation, fractional anisotropy, diffusion tensor imaging, treatment-resistant depression, frontal lobe function

目的 : これまでのwall-carving technique(WC)image は,動脈相の造影MDCT の画像データのみを用いて早期胃癌の描出能評価がなされている.本研究の目的は,動脈相ならびに門脈相の造影MDCT データでのWC 画像を用いて,早期胃癌の描出能向上の可能性について検討する.さらに描出能と病理学的所見と対比することで,それらの関連性を検討する.対象と方法 : 対象は,早期胃癌と診断され治療前に造影CT を施行した14症例14 病変(平均年齢/範囲 : 75.8 歳/61~86 歳,男/女 : 9/5).64列の多列検出器CT にて,動脈相として造影開始40 秒後と門脈相として60 秒後scan 開始タイミングで撮影された画像データを用いてWC 画像を作成した.WC 画像での癌病変の描出の有無と,病理学的所見である発生部位・肉眼的形態・病理学的分化度・病理学的深達度・線維化発達度・病変長径について関連性を調べた.結果 : 動脈相WC 画像では71.4%(10/14),門脈相WC 画像では71.4%(10/14)で描出されたが,動脈相と門脈相両者のWC 画像のいずれかでの描出は85.7%(12/14)と向上した.また動脈相・門脈相および両者のWC画像での高分化腺癌での描出能が高い傾向にあった.結論 : WC 画像は早期胃癌描出に優れた画像解析手法である.動脈相・門脈相両者でのWC画像で,病変描出能向上が得られる.MDCT での撮影方法について,さらなる造影タイミングの工夫で描出能が向上する可能性がある., Objective : The wall-carving (WC) imaging technique is used to evaluate early gastric cancer using multidetector row computed tomography (MDCT) image data for only the arterial phase. Our purpose was to investigate if WC images derived from portal phase MDCT images can enhance the visualization of early gastric cancer. Subjects and methods : Fourteen consecutive patients (average age/age range (years)= 75.8/61 to 86 ; male/female = 9/5) were enrolled. They were diagnosed with early gastric cancer and underwent contrast-enhanced MDCT before treatment. WC images of the arterial and portal phases were created from images scanned by 64-detector-row MDCT 40 and 60 seconds after the initiation of the contrast material injection, respectively. The correlation between the detection rates of lesions in the WC images and pathological findings was investigated. Results : Totals of 71.4% (10/14) of arterial phase WC images and 71.4% (10/14) of portal phase WC images showed lesions. The imaging ability improved to 85.7% (12/14) when the two sets of images were combined. Well-differentiated adenocarcinomas tended to be visualized better in WC images of any phases. Conclusion : WC is an excellent image analysis technique for visualizing early gastric cancer lesions. The depiction rates were improved by using a combination of arterial and portal WC images. The scan timing after the contrast material injection should be carefully investigated to improve the detection rate of lesions.
