Background:Intravenous thrombolysis (IVT) remains the only approved systemic reperfusion treatment for acute ischemic stroke (AIS), however there are scarce data regarding outcomes and complications of IVT in Greece. We evaluated safety and efficacy outcomes of IVT for AIS in Greece using the Safe Implementation of Thrombolysis in Stroke: International Stroke Thrombolysis Register (SITS-ISTR) dataset.Methods:All AIS patients treated with IVT in Greece between December 2002 and July 2017 and recorded in the SITS-ISTR were evaluated. Demographics, risk factors, baseline stroke severity [defined using National Institutes of Health Stroke Scale (NIHSS)], and onset-to-treatment time (OTT) were recorded. Safety outcomes included symptomatic intracranial hemorrhage (sICH) and 3-month mortality rates. The efficacy outcomes evaluated a reduction in baseline NIHSS score at 2 and 24 h following IVT onset, 3-month favorable functional outcome [FFO; modified Rankin scale (mRS) scores of 0–1] and 3-month functional independence (FI; mRS-scores of 0–2). The safety and efficacy outcomes were assessed comparatively with previously published data from SITS national and international registries.Results:A total of 523 AIS patients were treated with IVT in 12 Greek centers participating in the SITS-ISTR during the study period (mean age 62.4 ± 12.7; 34.6% women; median baseline NIHSS score: 11 points; median OTT: 150 min). The rates of sICH were 1.4%, 2.3%, and 3.8% according to the SIST-MOST, ECASS II, and NINDS criteria respectively. The median reduction in NIHSS score at 2 and 24 h was 3 [interquartile range (IQR): 1–5] and 5 (IQR: 2–8) points respectively. The 3-month FI, FFO and mortality were 66.5%, 55.6% and 7.9%. All safety and efficacy outcomes were comparable with available data from SITS-ISTR in other European countries.Conclusions:Our study underscores the safety and efficacy of IVT for AIS in Greece. Additional action is necessary in order to increase the availability of IVT in the Greek population and to include more centers in the SITS-ISTR.
Introduction: Establishment of a prospective stroke registry may promote the documentation and improvement of acute stroke care. We present the status of stroke management in Greece using the Registry of Stroke Care Quality (RES-Q) dataset. Methods: Consecutive patients with acute stroke were prospectively registered in RES-Q registry by contributing sites in Greece during the years 2017–2021. Demographic and baseline characteristics, acute management, and clinical outcomes at discharge were recorded. Stroke quality metrics, with a specific interest in the association between acute reperfusion therapies and functional recovery in ischemic stroke patients are presented. Results: A total of 3590 acute stroke patients were treated in 20 Greek sites (61% men, median age 64 years; median baseline NIHSS 4; 74% ischemic stroke). Acute reperfusion therapies were administered in almost 20% of acute ischemic stroke patients, with a door to needle and door to groin puncture times of 40 and 64 min, respectively. After adjustment for contributing sites, the rates of acute reperfusion therapies were higher during the time epoch 2020–2021 compared to 2017–2019 (adjusted OR 1.31; 95% CI 1.04–1.64; p < 0.022; Cochran-Mantel-Haenszel test). After propensity-score-matching, acute reperfusion therapies administration was independently associated with higher odds of reduced disability (one point reduction across all mRS scores) at hospital discharge (common OR 1.93; 95% CI 1.45–2.58; p < 0.001). Conclusions: Implementation and maintenance of a nationwide stroke registry in Greece may guide the stroke management planning, so that prompt patient transportation, acute reperfusion therapies, and stroke unit hospitalization become more widely accessible, improving the functional outcomes of stroke patients.
Background: Autoimmune encephalitis has been well described in oncological patients treated with immune checkpoint inhibitors (ICIs), as a paraneoplastic neurological syndrome. Central nervous system (CNS) infections from herpes viruses are also known to trigger secondary neurologic autoimmunity.Case Presentation: We hereby describe a patient with a recent history of cytomegalovirus (CMV) CNS infection and ongoing immunotherapy with the programmed-celldeath-protein-1(PD-1) inhibitor pembrolizumab for metastatic endometrial cancer.The patient presented with progressive encephalopathy along with cerebellar signs, rapidly evolving to status epilepticus requiring mechanical ventilation and advanced care unit (ACU) support. A serum paraneoplastic antibody panel revealed strongly positive anti-Zic4 antibodies. Despite first-line immunotherapy and aggressive anticonvulsant treatment, the patient died a few days postintubation. Conclusion:In anti-Zic4 encephalitis, both PD-1 inhibitor treatment and recent CMV viral insult may contribute to the development of neurological autoimmunity. Further research is needed to identify ways of predicting neurological damage in oncological patients treated with ICIs.
