Statin use and long-term risk of recurrent intracerebral haemorrhage: the MUCH-Italy.

BACKGROUND: Whether statin use after spontaneous intracerebral haemorrhage (ICH) increases the risk of recurrent ICH is uncertain. METHODS: In the setting of the Multicentric Study on Cerebral Haemorrhage in Italy we followed up a cohort of 30-day ICH survivors, consecutively admitted from January 2002 to July 2014, to assess whether the use of statins after the acute event is associated with recurrent cerebral bleeding. RESULTS: 1623 patients (mean age, 73.9±10.3 years; males, 55.9%) qualified for the analysis. After a median follow-up of 40.5 months (25th to 75th percentile, 67.7) statin use was not associated with increased risk of recurrent ICH either in the whole study group (adjusted HR, 0.99; 95% CI 0.64 to 1.53) or in the subgroups defined by haematoma location (deep ICH, adjusted HR, 0.74; 95% CI 0.35 to 1.57; lobar ICH, adjusted HR, 1.09; 95% CI 0.62 to 1.90), intensity of statins (low-moderate intensity statins, adjusted HR, 0.93; 95% CI 0.58 to 1.49; high-intensity statins, adjusted HR, 1.48; 95% CI 0.66 to 3.31) and use of statins before the index event (adjusted HR, 0.66; 95% CI 0.38 to 1.17). CONCLUSIONS: Statin use appears to be unrelated to the risk of ICH recurrence.

Risk Factors, and Clinical and Etiological Characteristics of Ischemic Strokes in COVID-19-Infected Patients: A Systematic Review of Literature.

BACKGROUND AND PURPOSE: Coronavirus disease 2019 (CO-VID-19) infection is an ongoing pandemic and worldwide health emergency that has caused important changes in healthcare systems. Previous studies reported an increased risk of thromboembolic events, including stroke. This systematic review aims to describe the clinical features and etiological characteristics of ischemic stroke patients with CO-VID-19 infection. METHOD: A literature search was performed in principal databases for studies and case reports containing data concerning risk factors, clinical features, and etiological characteristics of patients infected with COVID-19 and suffering from stroke. Descriptive and analytical statistics were applied. RESULTS: Overall, 14 articles were included for a total of 93 patients. Median age was 65 (IQR: 55-75) years with prevalence in males. Stroke occurred after a median of 6 days from COVID-19 infection diagnosis. Median National of Institute of Health Stroke Scale (NIHSS) score was 19. Cryptogenic (Cry) strokes were more frequent (51.8%), followed by cardioembolic etiology, and they occurred a long time after COVID-19 diagnosis compared with large-artery atherosclerosis strokes (ptrend: 0.03). The clinical severity of stroke was significantly associated with the severity grade of COVID-19 infection (ptrend: 0.03). CONCLUSIONS: Ischemic strokes in COVID-19-infected patients were clinically severe, affecting younger patients mainly with Cry and cardioembolic etiologies. Further multicenter prospective registries are needed to better describe the causal association and the effect of COVID-19 infection on stroke.

Mechanical thrombectomy with or without thrombolysis: A meta-analysis of RCTs.

BACKGROUND: Mechanical thrombectomy (MT) is effective in treating ischemic strokes due to large vessel occlusion. However, the risk-benefit ratio of intravenous thrombolysis (IVT) prior to MT is still unclear. Aim of the study was to provide a pooled analysis of only randomized controlled trials (RCTs) comparing direct MT (dMT) vs bridging treatment (IVT+MT). METHODS: PubMed, EMBASE and Cochrane Central were searched only for RCTs comparing IVT+MT vs dMT in ischemic stroke patients. Primary endpoint was functional independence at 90 days (mRS<3), while secondary endpoints were represented by successful recanalization (TICI>2a), mortality at 90 days and symptomatic intracranial hemorrhage (sICH). Odds ratios for endpoints were pooled with meta-analysis and compared between reperfusion strategies. RESULTS: The pooled analysis comprised 5 studies (n. patients = 1657). The rates for the primary endpoint were 39% and 34.5% for dMT and IVT+MT, respectively (OR 1.06; 95%CI 0.80-1.40). For the secondary endpoints, we did not observe significant differences between groups, even if the rate of successful recanalization was higher in IVT+MT treated patients (OR: 0.58; 95%CI 0.26-1.30;pheterogeneity = 0.002), without a significant increase in sICH rates (4.3% vs 5.5%; OR: 0.96; 95%CI 0.43-2.13;pheterogeneity = 0.26). Finally, mortality rates were 19.8% and 15.9% for dMT and IVT+MT, respectively. CONCLUSIONS: In this meta-analysis including only RCTs, dMT and bridging treatment were substantially equivalent for good functional outcome. IVT+MT was associated to higher rates of successful recanalization, even if not significant. Therefore, further adequately powered RCTs comparing dMT vs IVT+MT are warranted.

Endovascular treatment versus intravenous thrombolysis alone in isolated M2 occlusion: a meta-analysis.

BACKGROUND: Optimal reperfusion strategies for M2 occlusion are still uncertain, with previous studies questioning benefit of mechanical thrombectomy (MT) over intravenous thrombolysis alone (IVT). Here we systematically reviewed and meta-analyzed data from studies comparing IVT alone vs MT with/without previous IVT, to define risk/benefit profile of each paradigm. METHODS: The study followed PRISMA guidelines. PubMed, EMBASE, and Cochrane Central were searched only for RCTs comparing MT with or without IVT vs IVT alone in adults with acute ischemic stroke and M2 occlusion. Primary endpoint was functional independence at 90 days (modified Rankin Scale<3); secondary endpoints were represented by symptomatic intracranial hemorrhage (sICH) and good recanalization (TICI>2a). Odds ratios for endpoints were pooled with meta-analysis and compared between reperfusion strategies. RESULTS: Seven studies (n=779) were included, all of high quality. Rate of good functional outcome was similar for MT and IVT (62.4% vs 66.3%; OR=0.73; 95%CI: 0.38-1.41; pheterogeneity=0.008) (Fig. 1).sICH was significantly more frequent in the MT group (8.5%) vs IVT group (3%) (OR 2.76, 95%CI 1.19-6.36, pheterogeneity=0.14). Good recanalization (TICI>2a) rate was higher in MT group vs IVT alone group (81.2% vs 51.4%; OR 3.99; 95%CI: 1.98-8.94; pheterogeneity=0.80). CONCLUSIONS: IVT alone provides similar clinical benefit compared to MT with/without IVT in cases of M2 occlusion. MT quadruplicates rates of good recanalization, but triplicates risk of sICH. Further trials are needed to define if MT confers any advantage over IVT for M2 occlusion.

Reperfusion strategies in stroke due to isolated cervical internal carotid artery occlusion: systematic review and treatment comparison.

INTRODUCTION: Despite intravenous thrombolysis (IVT) and endovascular treatment (EVT) have been demonstrated effective in acute ischemic stroke (AIS) due to large vessel occlusions, there are still no conclusive data to guide treatment in stroke due to cervical internal carotid artery (ICA) occlusion. We systematically reviewed available literature to compare IVT, EVT, and bridging (IVT + EVT) and define optimal treatment. METHODS: Systematic review followed predefined protocol (Open-Science-Framework osf.io/bfykj ). MEDLINE, EMBASE, and Cochrane CENTRAL were searched. Results were restricted to studies in English, with sample size ≥ 10 and follow-up ≥30 days. Primary outcomes were favorable outcome (mRS ≤ 2), mortality, and symptomatic intracerebral hemorrhage(sICH), defined according to study original report. Newcastle-Ottawa scale was used for bias assessment. RESULTS: Seven records of 930 screened were included in meta-analysis. Quality of studies was low-to-fair in 5, good in 2. IVT (n = 450) did not differ for favorable outcome and mortality compared to EVT (n = 150), though having lower rate of sICH (OR = 0.4, 95% CI 0.2-0.8). Compared to IVT, bridging (IVT + EVT) was associated with higher rate of favorable outcome (OR = 2.2, 95% CI 1.3-3.7). Compared to EVT, bridging (IVT + EVT) provided higher rate of favorable outcome (OR = 1.9, 95% CI 1.1-3.4), with a marginally increased risk of sICH (OR = 2.1, 95% CI 1-4.4) but similar mortality rates. CONCLUSIONS: Our systematic review highlights that, in acute ischemic stroke associated with isolated cervical ICA occlusion, bridging (IVT + EVT) might lead to higher rate of functional independence at follow-up, without increasing mortality. The low quality of available studies prevents from drawing firm conclusions, and randomized-controlled clinical trials are critically needed to define optimal treatment in this AIS subgroup.

Impact of COVID-19 pandemic on acute stroke care: facing an epidemiological paradox with a paradigm shift.

BACKGROUND: During the coronavirus disease 2019 (COVID-19) outbreak, a decrease of stroke's hospital admissions and reperfusion therapy has been reported worldwide. This retrospective observational study assessed the volume of stroke cases managed in the Emergency Department (ED) and reperfusion therapies in an Italian stroke network with a high incidence of COVID-19, particularly to evaluate if the in-hospital rerouting and the switch from a drip-and-ship to a mothership model could assure an adequate volume of acute treatments. METHODS: We compared data from March 2020 with those from previous years and formulated five PICO questions regarding (1) incidence of stroke cases in the ED; (2) relation between stroke cases and COVID-19; (3) differences in the number of reperfusion therapies, (4) in the call-to-needle and door-to-needle times for intravenous thrombolysis, and (5) in the call-to-groin and door-to-groin times for thrombectomy. RESULTS: We found (1) a 28% decreased of confirmed stroke cases managed in the ED, (2) a negative correlation between stroke cases in ED and COVID-19 progression (rs = - .390, p = .030), and (3) a similar number of treatments in March 2020 and March 2019. The adoption of the mothership model (4) did not delay alteplase infusion (median call-to-needle p = .126, median door-to-needle p = .142) but led to (5) a significant reduction in median call-to-groin (p = .018) and door-to-groin times (p = .010). CONCLUSION: The "hospital avoidance" of stroke patients during the "stay-at-home" appeals needs to be considered for future public health campaigns. A prompt reorganization of the stroke network can guarantee optimal performances at times of crisis.

Bridging versus Direct Mechanical Thrombectomy in Acute Ischemic Stroke: A Subgroup Pooled Meta-Analysis for Time of Intervention, Eligibility, and Study Design.

BACKGROUND AND AIM: The risk/benefit profile of intravenous thrombolysis (IVT) prior to endovascular thrombectomy (EVT) in acute ischemic stroke is still unclear. We provide a systematic review and meta-analysis including studies comparing direct EVT (dEVT) vs. bridging treatment (IVT + EVT), defining the impact of treatment timing and eligibility to IVT on functional status and mortality. METHODS: Protocol was registered with PROSPERO (CRD42019135915) and followed PRISMA guidelines. PubMed, EMBASE, and Cochrane Central were searched for randomized controlled trials (RCTs), retrospective, and prospective studies comparing IVT + EVT vs. dEVT in adults (≥18) with acute ischemic stroke. Primary endpoint was functional independence at 90 days (modified Rankin Scale <3); secondary endpoints were (i) good recanalization (thrombolysis in cerebral infarction >2a), (ii) mortality, and (iii) symptomatic intracranial hemorrhage (sICH). Subgroup analysis was performed according to study type, eligibility to IVT, and onset-to-groin timing (OGT), stratifying studies for similar OGT. ORs for endpoints were pooled with meta-analysis and compared between reperfusion strategies. RESULTS: Overall, 35 studies were included (n = 9,117). No significant differences emerged comparing patients undergoing dEVT and bridging treatment for gender, hypertension, diabetes, National Institute of Health Stroke Scale score at admission. Regarding primary endpoint, IVT + EVT was superior to dEVT (OR 1.44, 95% CI 1.22-1.69, p < 0.001, pheterogeneity<0.001), with number needed to treat being 18 in favor of IVT + EVT. Results were confirmed in studies with similar OGT (OR 1.66; 95% CI 1.21-2.28), shorter OGT for IVT + EVT (OR 1.53, 95% CI 1.27-1.85), and independently from IVT eligibility (OR 1.53, 95% CI 1.29-1.82). Mortality at 90 days was higher in dEVT (OR 1.38; 95% CI 1.09-1.75), but no significant difference was noted for sICH. However, considering data from RCT only, reperfusion strategies had similar primary (OR 0.91, 95% CI 0.6-1.39) and secondary endpoints. Differences in age and clinical severity across groups were unrelated to the primary endpoint. CONCLUSIONS: Compared to dEVT, IVT + EVT associates with better functional outcome and lower mortality. Post hoc data from RCTs point to substantial equivalence of reperfusion strategies. Therefore, an adequately powered RCTs comparing dEVT versus IVT + EVT are warranted.

Incidence of early poststroke seizures during reperfusion therapies in patients with acute ischemic stroke: An observational prospective study: (TESI study: "Trombolisi/Trombectomia e crisi Epilettiche precoci nello Stroke Ischemico").

INTRODUCTION: The aim of this study was to prospectively investigate the occurrence of early poststroke seizures (within 7 days of stroke) in patients undergoing reperfusion therapies (intravenous rtPA [recombinant tissue plasminogen activator] and/or endovascular thrombectomy) in comparison to those not undergoing these procedures. METHODS: Patients aged ≥18 years with acute ischemic stroke admitted in five Italian centers were prospectively recruited. Clinical data, details on stroke type and etiology, stroke treatment, and radiological data were collected. The frequency of early poststroke seizures was assessed, and predictive factors for their occurrence were evaluated. RESULTS: Five hundred and sixteen patients (262 in the reperfusion therapies group) were included. Stroke severity on admission and at discharge was higher among patients undergoing reperfusion therapies. Ten patients (3.8%) undergoing reperfusion therapies and 6 (2.3%) of those not receiving these treatments experienced early poststroke seizures (p = 0.45). There were no differences in any of the baseline characteristics between patients experiencing and those not experiencing early seizures. CONCLUSION: The incidence of early poststroke seizures was overall rare, and no significant differences emerged between patients receiving and those not receiving reperfusion therapies.

Headache in cervicocerebral artery dissection.

Cervicocerebral artery dissection (CAD) is one of the more frequent causes of stroke in young adults with rates of up to 25%. Predisposing and risk factors for CAD are very different, and an etiological classification is based on the presence of a previous minor or major trauma, differentiating traumatic from spontaneous CAD. Headache represents one of the main initial symptoms for this pathological condition, probably due to the release of pro-inflammatory neurotransmitters from nerve terminals near the injured vessel. For its peculiar characteristics, the headache due to CAD has been defined with specific ICHD-3 criteria. In many cases, headache is associated with other signs related to the dissection or cerebral ischemia. In this systematic review of literature, headache was reported in more than 70% of cases with CAD with a prevalence in vertebrobasilar dissections. More than half of patients suffered a severe pain that was usually located in fronto-temporal and occipito-nuchal regions in the case of dissections in the anterior and posterior circulation, respectively. For the high stroke risk, CAD has to be promptly diagnosed with MRI or CTA and treated with anticoagulants or antithrombotics.

The organisation of the acute ischemic stroke management: key notes of the Italian Neurological Society and of the Italian Stroke Organization.

The main aim of acute ischemic stroke treatment is the as much possible prompt, safe and effective arterial recanalisation, in order to restore reperfusion into the ischemic brain area. The procedures obtaining this result are rapidly evolving and in the last years, we observed new evidences that affirmed the therapeutical benefit of the concomitant treatment using endovenous thrombolysis and mechanical thrombectomy in selected patients with ischemic stroke. However, all treatments are time-sensitive and the main limitation for their application is represented by the time. For this reason, the optimisation of the acute stroke management that includes a pre-hospital and an in-hospital phase is essential to reduce the avoidable delay, increasing the number of patients potentially treatable. The purpose of this document is to define the main elements and to suggest the principal key points constituting the optimal pathway of stroke management in Italian care settings, in line with the recommendations coming from the current national and international guidelines.

(123) I-2ß-carbomethoxy-3ß-(4-iodophenyl)-N-(3-fluoropropyl) nortropane single photon emission computed tomography and (123) I-metaiodobenzylguanidine myocardial scintigraphy in differentiating dementia with lewy bodies from other dementias: A comparative study.

OBJECTIVE: To compare the diagnostic value of striatal (123) I-2ß-carbomethoxy-3ß-(4-iodophenyl)-N-(3-fluoropropyl) nortropane ((123) I-FP-CIT) single photon emission computed tomography (SPECT) and (123) I-metaiodobenzylguanidine ((123) I-MIBG) myocardial scintigraphy in differentiating dementia with Lewy bodies (DLB) from other dementia types. METHODS: This prospective longitudinal study included 30 patients with a clinical diagnosis of DLB and 29 patients with non-DLB dementia (Alzheimer disease, n = 16; behavioral variant frontotemporal dementia, n = 13). All patients underwent (123) I-FP-CIT SPECT and (123) I-MIBG myocardial scintigraphy within a few weeks of clinical diagnosis. All diagnoses at each center were agreed upon by the local clinician and an independent expert, both unaware of imaging data, and re-evaluated after 12 months. Each image was visually classified as either normal or abnormal by 3 independent nuclear physicians blinded to patients' clinical data. RESULTS: Overall, sensitivity and specificity to DLB were respectively 93% and 100% for (123) I-MIBG myocardial scintigraphy, and 90% and 76% for (123) I-FP-CIT SPECT. Lower specificity of striatal compared to myocardial imaging was due to decreased (123) I-FP-CIT uptake in 7 non-DLB subjects (3 with concomitant parkinsonism) who had normal (123) I-MIBG myocardial uptake. Notably, in our non-DLB group, myocardial imaging gave no false-positive readings even in those subjects (n = 7) with concurrent medical illnesses (diabetes and/or heart disease) supposed to potentially interfere with (123) I-MIBG uptake. INTERPRETATION: (123) I-FP-CIT SPECT and (123) I-MIBG myocardial scintigraphy have similar sensitivity for detecting DLB, but the latter appears to be more specific for excluding non-DLB dementias, especially when parkinsonism is the only "core feature" exhibited by the patient. Our data also indicate that the potential confounding effects of diabetes and heart disease on (123) I-MIBG myocardial scintigraphy results might have been overestimated. Ann Neurol 2016;80:368-378.

Prevalence of Patent Foramen Ovale in Ischaemic Stroke in Italy: Results of SISIFO Study.

BACKGROUND: Although several authors have studied the association between patent foramen ovale (PFO) and ischaemic stroke, the matter is still controversial; few have suggested an association between cryptogenetic stroke and PFO, while others have denied this association. The aim of this study was to evaluate PFO prevalence in the whole ischaemic stroke population, independently from age and stroke subtypes and to identify the characteristics associated with the presence of PFO. METHODS: SISIFO study was a multicenter, prospective, single-wave, cross-sectional survey conducted on consecutive patients with acute ischemic stroke admitted to selected clinical centres. Data regarding vascular risk factors were registered for each patient; all patients underwent computed tomography scan and/or magnetic resonance imaging of the brain; an electrocardiogram and standard laboratory blood tests were performed. A Doppler ultrasound study of extra-cranial arteries was performed too. The cases were classified according to TOAST and OCSP criteria. Each patient underwent transcranial Doppler or transcranial color-coded duplex sonography with bubble test as diagnostic tool for right-to-left-shunt. Where right-to-left shunt was detected, PFO presence was confirmed by echocardiography. FINDINGS: 1,130 consecutive patients were included. We found a PFO in 247 (21.9%; 95% CI, 19.5-24.3%) patients; PFO was present in 23.5% of patients with cryptogenic stroke and in 21.3% of patients with stroke of known causes; this difference was not statistically significant. At the univariate analysis, decreasing age, hypertension, diabetes mellitus, and atrial fibrillation, and stroke characteristics such as NIHSS, OCSP and TOAST were predictors of PFO presence. At the multivariate analysis, we found a significant interaction between age and OCSP syndrome. Being LACI the reference category, the prevalence of PFO in PACI and POCI decreased significantly along with age, whereas there was no change in TACI. CONCLUSION: If any relationship exists between stroke and PFO, this is more likely in PACI and POCI at a younger age. Our results are consistent with recent findings that underline PFO alone must not be considered a significant independent predictor for stroke; so the presence of PFO alone doesn't permit rushed causal correlations or 'therapeutic aggressiveness'.

Prevalence of patent foramen ovale in ischemic stroke in Italy: the SISIFO study.

Patent foramen ovale (PFO) is a common congenital anatomical defect in the general population with a mean prevalence of 20 %. Transcranial Doppler sonography and echocardiography, both with infusion of agitated saline as an echo contrast, have been introduced for the diagnosis of PFO. Transesophageal echocardiography is considered the gold standard. Several studies have suggested an association between cryptogenetic stroke and PFO, but the role of this condition as a risk factor for stroke is still debated. The aims of this prospective multicentre study are the evaluation of PFO prevalence in the whole ischemic stroke population and the identification of a stroke recurrence profile risk in patients with PFO. All consecutive patients admitted for acute ischemic stroke and with a confirmed diagnosis at discharge are eligible cases for the study. Demographic and vascular risk factors are registered. Clinical severity is summarized by the National Institute of Health stroke scale. Echocardiographic and transcranial studies are performed in each patient to detect the presence of PFO. Prevalence of PFO will be calculated with 95 % CIs. Univariate analysis will be performed to detect the correlation of PFO with different registered factors and multivariable analysis with PFO as independent variable. The present study should contribute to better identify the role of PFO in ischemic stroke risk and recurrence-related events. Qualifying findings of the study are represented by the high number of enrolled patients, the prospective methodology of the study and the presence of secondary instrumental endpoints.

Mechanical Thrombectomy in Ischemic Stroke with a Large Infarct Core: A Meta-Analysis of Randomized Controlled Trials.

Background/Objectives: Endovascular treatment (EVT) is recommended for acute ischemic stroke due to large-vessel occlusion (LVO) and an Alberta Stroke Program Early CT Score (ASPECTS) ≥ 6. Randomized controlled trials (RCTs) have recently become available on EVT effects in people with LVO-related large core stroke (ASPECTS 0-5). Here, we provide an updated meta-analysis of the EVT effect on functional neurological status in people with large-core stroke. Methods: The study followed the PRISMA guidelines. PubMed, EMBASE and Cochrane Central were searched for RCTs comparing EVT vs. best medical treatment (BMT) in large-core LVO stroke. The primary outcome was functional independence at 90 days (modified Rankin Scale; mRS 0-2). The secondary outcomes were symptomatic intracranial hemorrhage (sICH), good functional outcome (mRS 0-3) and excellent functional outcome (mRS 0-1). EVT vs. BMT was compared through random effect meta-analysis. Heterogeneity was assessed with the I2 and Q test and risk of bias reported according to the RoB2 tool. Results: Six RCTs were included (n = 1656 patients). All studies had a moderate risk of bias, with blinding bias due to the nature of the intervention, potential allocation bias and incomplete outcome reporting. Functional independence was significantly more frequent in the EVT vs. BMT group (OR = 2.47, 95% CI = 1.52-4.03, p < 0.001). sICH rates (OR = 1.77, 95% CI = 1.01-3.11, p = 0.04) and good functional outcome (OR = 2.20; 95% CI = 1.72-2.81, p < 0.001) were more frequent in the EVT vs. BMT group, while the rates of mRS 0-1 did not differ. Conclusions: In patients with large-core stroke and LVO, EVT plus BMT as compared to BMT alone carries a significant increase in independent ambulation and good functional outcome at 3 months despite the marginal increase in sICH.

Early seizures and risk of epilepsy and death after intracerebral haemorrhage: The MUCH Italy.

INTRODUCTION: It is unclear which patients with non-traumatic (spontaneous) intracerebral haemorrhage (ICH) are at risk of developing acute symptomatic seizures (provoked seizures occurring within the first week after stroke onset; early seizures, ES) and whether ES predispose to the occurrence of remote symptomatic seizures (unprovoked seizures occurring more than 1 week after stroke; post-stroke epilepsy, PSE) and long-term mortality. PATIENTS AND METHODS: In the setting of the Multicenter Study on Cerebral Haemorrhage in Italy (MUCH-Italy) we examined the risk of ES and whether they predict the occurrence of PSE and all-cause mortality in a cohort of patients with first-ever spontaneous ICH and no previous history of epilepsy, consecutively hospitalized in 12 Italian neurological centers from 2002 to 2014. RESULTS: Among 2570 patients (mean age, 73.4 ± 12.5 years; males, 55.4%) 228 (8.9%) had acute ES (183 (7.1%) short seizures and 45 (1.8%) status epilepticus (SE)). Lobar location of the hematoma (OR, 1.49; 95% CI, 1.06-2.08) was independently associated with the occurrence of ES. Of the 2,037 patients who were followed-up (median follow-up time, 68.0 months (25th-75th percentile, 77.0)), 155 (7.6%) developed PSE. ES (aHR, 2.34; 95% CI, 1.42-3.85), especially when presenting as short seizures (aHR, 2.35; 95% CI, 1.38-4.00) were associated to PSE occurrence. Unlike short seizures, SE was an independent predictor of all-cause mortality (aHR, 1.50; 95% CI, 1.005-2.26). DISCUSSION AND CONCLUSION: The long-term risk of PSE and death after an ICH vary according to ES subtype. This might have implications for the design of future clinical trials targeting post-ICH epileptic seizures.

Time to hospital admission and start of treatment in patients with ischemic stroke in northern Italy and predictors of delay.

BACKGROUND AND PURPOSE: Early treatment (i.e. thrombolysis) is crucial for a successful care of ischemic stroke. In the management of stroke, two phases are crucial: the pre-hospital and the in-hospital interval. This work investigated factors influencing pre- and in-hospital delay in a large geographic area of Northern Italy. METHODS: Enrolled were patients presenting with ischemic stroke in four administrative districts of Northern Italy (Como, Lecco, Sondrio and Varese) over a 4-month period. Pre-hospital time and in-hospital time with single management steps were recorded prospectively. Age, gender, recruiting hospital, EMS transport and triage codes, clinical severity and thrombolytic treatment were also recorded. Univariate and multivariate analysis of factors predicting pre- and in-hospital delay were performed. RESULTS: Median pre-hospital time and in-hospital time were, respectively, 120 min (interquartile range, IQR 62-271) and 150 min (IQR 80-214). Pre-hospital time was halved in patients hospitalized via EMS (p<0.001) and clinically more severe (p<0.001). At multivariate analysis, transport code was associated with delay at any time (p<0.05). CONCLUSIONS: EMS use and transport code predicted treatment delay in patients with ischemic stroke. A more intensive use of EMS and high urgency codes could help increase the number of stroke patients treated appropriately.

Seizures in patients with chronic hepatitis C treated with NS3/4A protease inhibitors: does pharmacological interaction play a role?

The addition of NS3/4A protease inhibitors boceprevir and telaprevir to pegylated interferon (Peg-IFN)-α and ribavirin for the treatment of hepatitis C virus (HCV) genotype 1-infected patients has led to higher rates of virological response and adverse events. Among the several side effects of interferon, neuropsychiatric symptoms have been described, particularly depression and anxiety, occurring in about 25% of patients. Although seizures have been reported in interferon-treated patients with multiple sclerosis and in a variety of malignancies, the epileptogenic potential of interferon-α in the treatment of HCV infection is considered minimal. In this report we present a new onset of seizures occurring in 2 patients during anti-HCV therapy in association with Peg-IFN, ribavirin and HCV protease inhibitors.
