Long-term neurological outcome in patients presenting with encephalitis.

Background: Advances in encephalitis research have improved the definition and management of encephalitis during the acute phase. Still, little is known about long-term outcomes in different subtypes of encephalitis.

Objectives: To analyze the prevalence and predictors of long-term clinical outcomes in different subtypes of encephalitis.

SARS-CoV-2 antibodies in inflammatory neurological conditions: a multicentre retrospective comparative study.

It is well established that neurological and non-neurological autoimmune disorders can be triggered by viral infections. It remains unclear whether SARS-CoV-2 infection induces similar conditions and whether they show a distinctive phenotype. We retrospectively identified patients with acute inflammatory CNS conditions referred to our laboratory for antibody testing during the pandemic (March 1 to August 31, 2020).

Timely Leukapheresis May Interfere with the "Fitness" of Lymphocytes Collected for CAR-T Treatment in High Risk DLBCL Patients.

The development of chimeric antigen receptor (CAR)-T cell therapy has revolutionized the treatment of hematological diseases. However, approximately 60% of patients relapse after CAR-T cell therapy, and no clear cause for this failure has been identified. The objective of the Bio-CAR-T BS study (ClinicalTrials.

Neurological complications in adult allogeneic hematopoietic stem cell transplant patients: Incidence, characteristics and long-term follow-up in a multicenter series.

Neurological complications (NCs) represent a diagnostic and clinical challenge in allogeneic hematopoietic stem cell transplant (alloHSCT) patients. We retrospectively analyzed NC incidence, etiology, timing, characteristics, outcome, and long-term effects in 2384 adult patients transplanted in seven Italian institutions between January 2007 and December 2019. Ninety-three (3.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Encephalitis Is a Cytokine Release Syndrome: Evidences From Cerebrospinal Fluid Analyses.

Background: Recent findings indicated that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-related neurological manifestations involve cytokine release syndrome along with endothelial activation, blood brain barrier dysfunction, and immune-mediated mechanisms. Very few studies have fully investigated the cerebrospinal fluid (CSF) correlates of SARS-CoV-2 encephalitis.

Methods: Patients with polymerase chain reaction (PCR)-confirmed SARS-CoV-2 infection and encephalitis (COV-Enc), encephalitis without SARS-CoV-2 infection (ENC), and healthy controls (HC) underwent an extended panel of CSF neuronal (neurofilament light chain [NfL], T-tau), glial (glial fibrillary acidic protein [GFAP], soluble triggering receptor expressed on myeloid cells 2 [sTREM2], chitinase-3-like protein 1 [YKL-40]) and inflammatory biomarkers (interleukin [IL]-1β, IL-6, Il-8, tumor necrosis factor [TNF] α, CXCL-13, and β2-microglobulin).

Clinical Presentation and Outcomes of Severe Acute Respiratory Syndrome Coronavirus 2-Related Encephalitis: The ENCOVID Multicenter Study.

Background: Several preclinical and clinical investigations have argued for nervous system involvement in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Some sparse case reports have described various forms of encephalitis in coronavirus disease 2019 (COVID-19) disease, but very few data have focused on clinical presentations, clinical course, response to treatment, and outcomes.

Methods: The SARS-CoV-2 related encephalopaties (ENCOVID) multicenter study included patients with encephalitis with full infectious screening, cerebrospinal fluid (CSF), electroencephalography (EEG), and magnetic resonance imaging (MRI) data and confirmed SARS-CoV-2 infection recruited from 13 centers in northern Italy.

Clinical characteristics and outcomes of inpatients with neurologic disease and COVID-19 in Brescia, Lombardy, Italy.

Objective: To report clinical and laboratory characteristics, treatment, and clinical outcomes of patients admitted for neurologic diseases with and without coronavirus disease 2019 (COVID-19).

Methods: In this retrospective, single-center cohort study, we included all adult inpatients with confirmed COVID-19 admitted to a neuro-COVID unit beginning February 21, 2020, who had been discharged or died by April 5, 2020. Demographic, clinical, treatment, and laboratory data were extracted from medical records and compared (false discovery rate corrected) to those of neurologic patients without COVID-19 admitted in the same period.

Steroid-Responsive Encephalitis in Coronavirus Disease 2019.

Coronavirus disease 2019 (COVID-19) infection has the potential for targeting the central nervous system, and several neurological symptoms have been described in patients with severe respiratory distress. Here, we described the case of a 60-year-old patient with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection but only mild respiratory abnormalities who developed an akinetic mutism attributable to encephalitis. Magnetic resonance imaging was negative, whereas electroencephalography showed generalized theta slowing.

Mitochondrial Neurogastrointestinal Encephalomyopathy (MNGIE-MTDPS1).

Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE-MTDPS1) is a devastating autosomal recessive disorder due to mutations in , which cause a loss of function of thymidine phosphorylase (TP), nucleoside accumulation in plasma and tissues, and mitochondrial dysfunction. The clinical picture includes progressive gastrointestinal dysmotility, cachexia, ptosis and ophthalmoparesis, peripheral neuropathy, and diffuse leukoencephalopathy, which usually lead to death in early adulthood. Other two MNGIE-type phenotypes have been described so far, which are linked to mutations in and genes.

Mitochondrial diseases: advances and issues.

Mitochondrial diseases (MDs) are a clinically heterogeneous group of disorders caused by a dysfunction of the mitochondrial respiratory chain. They can be related to mutation of genes encoded using either nuclear DNA or mitochondrial DNA. The advent of next generation sequencing and whole exome sequencing in studying the molecular bases of MDs will bring about a revolution in the field of mitochondrial medicine, also opening the possibility of better defining pathogenic mechanisms and developing novel therapeutic approaches for these devastating disorders.

Connective tissue anomalies in patients with spontaneous cervical artery dissection.

Objective: To investigate the prevalence of connective tissue abnormalities in patients with spontaneous cervical artery dissections (sCeAD).

Methods: We systematically assessed clinically detectable signs of connective tissue aberration in a series of consecutive patients with sCeAD and of age- and sex-matched patients with ischemic stroke unrelated to CeAD (non-CeAD IS) by a standard examination protocol including 68 items, and performed extensive molecular investigation for hereditary connective tissue disorders in all patients with sCeAD.

Results: The study group included 84 patients with sCeAD (mean age, 44.

Predictors of long-term recurrent vascular events after ischemic stroke at young age: the Italian Project on Stroke in Young Adults.

Background: Data on long-term risk and predictors of recurrent thrombotic events after ischemic stroke at a young age are limited.

Methods And Results: We followed 1867 patients with first-ever ischemic stroke who were 18 to 45 years of age (mean age, 36.8±7.

Antithrombotic medications and the etiology of intracerebral hemorrhage: MUCH-Italy.

Objective: To test the hypothesis that the effect of antithrombotic medications on the risk of intracerebral hemorrhage (ICH) varies according to the location of the hematoma.

Methods: Consecutive patients with ICH were enrolled as part of the Multicenter Study on Cerebral Hemorrhage in Italy (MUCH-Italy). Multivariable logistic regression models served to examine whether risk factors for ICH and location of the hematoma (deep vs lobar) predict treatment-specific ICH subgroups (antiplatelets-related ICH and oral anticoagulants [OACs]-related ICH).

Cognitive outcomes after acute coronary syndrome: a population based comparison with transient ischaemic attack and minor stroke.

Objective: Acute coronary syndrome (ACS) is associated with increased risk of cognitive decline when compared with controls, but case:control studies are subject to selection bias. We therefore compared cognitive outcomes in ACS with transient ischaemic attack (TIA) and minor stroke, diseases with similar risk factor burden generally considered to be at high risk of cognitive decline.

Design: Prospective population based cohort study

Setting: Oxford Vascular Study (OXVASC) carried out within a defined population of 91 000 in Oxfordshire, UK.

Pure midbrain ischemia and hypoplastic vertebrobasilar circulation.

Isolated midbrain infarction is rare and little is known about etiology and patient's long-term follow up. We aimed to describe the clinical features, the causative diseases and the outcome of patients with isolated midbrain infarction who were admitted to our center, focusing on vascular abnormalities of posterior circulation. All patients with first acute ischemic stroke limited to the midbrain were included and their demographic features, neurological symptoms, neuroimaging data, and cardiovascular risk factors were recorded.

Complications of acute stroke and the occurrence of early seizures.

Background: Seizures are common neurological consequences of stroke. Although a number of factors including stroke severity on admission, cortical involvement, and stroke subtype have been consistently associated with post-stroke seizures, the effect that medical and neurological complications of stroke, occurring in the very acute phase, might have on such a risk has never been adequately explored. In the present study we aimed at determining the extent to which complications within the first week of stroke influence the risk of early seizures (ES).

Obesity and the risk of intracerebral hemorrhage: the multicenter study on cerebral hemorrhage in Italy.

Background And Purpose: The effect of obesity on the risk of intracerebral hemorrhage (ICH) may depend on the pathophysiology of vessel damage. To further address this issue, we investigated and quantified the correlations between obesity and obesity-related conditions in the causal pathways leading to ICH.

Methods: A total of 777 ICH cases ≥ 55 years of age (287 lobar ICH and 490 deep ICH) were consecutively enrolled as part of the Multicenter Study on Cerebral Hemorrhage in Italy and compared with 2083 control subjects by a multivariate path analysis model.

Headache due to spontaneous intracranial hypotension and subsequent cerebral vein thrombosis.

Cerebral vein thrombosis (CVT) is a rare complication of spontaneous intracranial hypotension (SIH). When to suspect a thrombotic disorder during the course of intracranial hypotension is not fully elucidated. A 48-year-old woman was admitted because of SIH with no signs of CVT on neuroimaging.

Grange syndrome: an identifiable cause of stroke in young adults.

Grange syndrome is a disorder characterized by arterial occlusive disease, hypertension, congenital cardiac defects, bone fragility, brachysyndactyly, and learning disabilities. It was first described in four members of the same family and in two sporadic cases thereafter, suggesting the possibility of various patterns of inheritance. We report on the case of an 18-year-old female presenting with subarachnoid hemorrhage due to the rupture of a basilar artery aneurysm, and with distinctive systemic features including extensive vasculopathy, facial dysmorphisms and brachysyndactyly, consistent with the diagnosis of Grange syndrome.

Thromboembolic complications of heparin-induced thrombocytopenia.

Heparin-induced thrombocytopenia (HIT) is an adverse effect of heparin therapy which can be responsible for thrombotic events with embolic consequences. Although ischemic stroke is a well known consequence of HIT, few cases of cerebral ischemia of arterial origin have been reported so far. A 38-year-old man was admitted because of acute multiple ischemic strokes and pulmonary embolism which occurred during treatment with low molecular weight heparin as prophylactic therapy for orthopedic surgery.

Large middle cerebral artery and panhemispheric infarction.

Large middle cerebral artery (MCA) and panhemispheric stroke represent a minority of cerebral ischemic events, yet they are responsible for a disproportionate share of morbidity and mortality. Malignant infarction with formation of cerebral edema is a common cause for secondary neurologic deterioration. Despite intensive medical and surgical care, prognosis is often poor and mortality may be as high as 60-80%.

Interaction between proatherosclerotic factors and right-to-left shunt on the risk of cryptogenic stroke: the Italian Project on Stroke in Young Adults.

Objective: To explore the interaction effects between cardiac interatrial right-to-left shunt (RLS) and proatherosclerotic factors on the risk of brain ischaemia.

Design: Multicentre Italian case-control study.

Setting: University hospitals.
