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., Competing Interests: Declaration of conflicting interestThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: Dr Ciccone reports grants from Daiichi-Sankyo; grants from Italfarmaco; and grants from Alexion Pharmaceuticals.Dr Paciaroni reports compensation from SANOFI-AVENTIS U.S. LLC for other services; compensation from PFIZER CANADA INC for other services; compensation from iRhythm Technologies for other services; compensation from Daiichi Sankyo Europe GmbH for other services; and compensation from Bristol-Myers Squibb for other services.The other Authors have nothing to disclose.

Background: Fabry disease (FD) is a treatable X-linked lysosomal storage disorder caused by GLA gene variants leading to alpha-galactosidase A deficiency. FD is a rare cause of stroke, and it is still controversial whether in stroke patients FD should be searched from the beginning or at the end of the diagnostic workup (in cryptogenic strokes)., Methods: Fabry-Stroke Italian Registry is a prospective, multicentric screening involving 33 stroke units. FD was sought by measuring α-galactosidase A activity (males) and by genetic tests (males with reduced enzyme activity and females) in patients aged 18-60 years hospitalized for TIA, ischemic stroke, or intracerebral hemorrhage. We diagnosed FD in patients with 1) already known pathogenic GLA variants; 2) novel GLA variants if additional clinical, laboratory, or family-derived criteria were present., Results: Out of 1906 patients, we found a GLA variant in 15 (0.79%; 95%CI 0.44-1.29) with a certain FD diagnosis in 3 (0.16%; 95%CI 0.03-0.46) patients, none of whom had hemorrhage. We identified 1 novel pathogenic GLA variant. Ischemic stroke etiologies in carriers of GLA variants were: cardioaortic embolism (33%), small artery occlusion (27%), other causes (20%), and undetermined (20%). Mild severity, recurrence, previous TIA, acroparesthesias, hearing loss, and small artery occlusion were predictors of GLA variant., Conclusion: In this large multicenter cohort the frequency of FD and GLA variants was consistent with previous reports. Limiting the screening for GLA variants to patients with cryptogenic stroke may miss up to 80% of diagnoses. Some easily recognizable clinical features could help select patients for FD screening., Competing Interests: Declaration of competing interest IR received travel grants and speaker's honoraria from Takeda, Sanofi, and Amicus; PN received speaker's honoraria from Takeda, Sanofi, and Amicus; MZ received fees as consultant and advisory board member from Takeda, Sanofi, and Amicus; SS received personal fees as speaker or advisor (Abbott, Allergan-Abbvie, AstraZeneca, Eli Lilly, Lundbeck, Novartis, NovoNordisk, Pfizer, Teva), research grants (Allergan, Novartis, Uriach), and fees for CME/education (Medscape, Neurodiem Ology Medical Education); UA received speaker's fees and honoraria from EISAI; AM received speaker's honoraria and travel grants from Takeda, Sanofi, and Amicus; DI received speaker's honoraria from Takeda.

Objective: Recent evidence suggests that anti-Ro/SSA antibodies, strongly associated with the development of congenital heart block, may also be arrhythmogenic for the adult heart. In fact, anti-Ro/SSA-positive patients with connective tissue disease (CTD) frequently display corrected QT (QTc) prolongation associated with an increase in ventricular arrhythmias. However, QTc prolongation prevalence markedly differs throughout the studies (10-60%), but the reason why is not yet clear. The aim of this study was to evaluate whether anti-Ro/SSA-associated QTc prolongation in adult patients with CTD is related to antibody level and specificity., Methods: Forty-nine adult patients with CTD underwent a resting 12-lead electrocardiogram recording to measure QTc interval, and a venous withdrawal to determine anti-Ro/SSA antibody level and specificity (anti-Ro/SSA 52 kd and anti-Ro/SSA 60 kd) by immunoenzymatic methods and Western blotting., Results: In our population, a direct correlation was demonstrated between anti-Ro/SSA 52-kd level and QTc duration (r = 0.38, P = 0.007), patients with a prolonged QTc had higher levels of anti-Ro/SSA 52 kd with respect to those with a normal QTc (P = 0.003), and patients with a moderate to high level (≥50 units/ml) of anti-Ro/SSA 52 kd showed a longer QTc interval (P = 0.008) and a higher QTc prolongation prevalence (P = 0.008) than those with a low positive/negative level (<50 units/ml). On the contrary, no association was found between QTc and anti-Ro/SSA 60-kd level., Conclusion: In anti-Ro/SSA-positive adult patients with CTD, the occurrence of QTc prolongation seems strictly dependent on the anti-Ro/SSA 52-kd level. This finding, possibly explaining the different QTc prolongation prevalence reported, strengthens the hypothesis that an extremely specific autoimmune cross-reaction is responsible for the anti-Ro/SSA-dependent interference on ventricular repolarization., (Copyright © 2011 by the American College of Rheumatology.)
