Aim: The aim of this study was to re‐evaluate risk factors for post‐ICH epilepsy (PICHE) and examine the impact of surgical hematoma evacuation on epilepsy development after ICH. Background and purpose: Epilepsy is a common complication after intracerebral hemorrhage (ICH). Information on risk factors is still scarce and the role of ICH evacuation remains uncertain. Methods: We retrospectively included patients with spontaneous ICH treated in our hospital in 2006–2019. Patients' medical records were analyzed. In addition, mailed questionnaires and telephone interviews were used to complete the dataset. Uni‐ and multivariable hazard ratios (HRs) were applied to investigate risk factors for PICHE and the impact of surgical ICH evacuation. Results: Among 587 ICH patients available for analyses, 139 (23.7%) developed PICHE (mean follow‐up 1795 ± 1378 days). The median time of epilepsy onset was 7 months after ICH (range 1–132 months). Risk factors associated with PICHE were cortical hemorrhage (multivariable HR 1.65 [95% CI 1.14–2.37]; p = 0.008), ICH volume > 10 ml (multivariable HR 1.91 [95% CI 1.33–2.73]; p < 0.001) and acute symptomatic seizures (multivariable HR 1.81 [95% CI 1.20–2.75]; p = 0.005). Patients with cortical ICH > 10 ml who underwent surgical hematoma evacuation were less likely to develop epilepsy than those with conservative treatment alone (multivariable HR 0.26 [95% CI 0.08–0.84]; p = 0.025). Conclusions: Post‐ICH epilepsy is frequent and predicted by large cortical ICH and acute symptomatic seizures. Hematoma evacuation reduced the risk of PICHE by more than 70% in patients with large cortical ICH. This finding could be considered in the clinical decision making on the acute treatment of ICH.

Aims: This study determined the influence of age on bleeding characteristics and clinical outcomes in primary spontaneous (non-OAC), vitamin K antagonist-related (VKA-) and non-vitamin K antagonist oral anticoagulant-related (NOAC-) ICH. Methods: Pooled individual patient data of multicenter cohort studies were analyzed by logistic regression modelling and propensity-score-matching (PSM) to explore the influence of advanced age on clinical outcomes among non-OAC-, VKA-, and NOAC-ICH. Primary outcome measure was functional outcome at three months assessed by the modified Rankin Scale, dichotomized into favorable (mRS = 0–3) and unfavorable (mRS = 4–6) functional outcome. Secondary outcome measures included mortality, hematoma characteristics, and frequency of invasive interventions. Results: In VKA-ICH 33.5% (670/2001), in NOAC-ICH 44.2% (69/156) and in non-OAC-ICH 25.2% (254/1009) of the patients were ≥80 years. After adjustment for treatment interventions and relevant parameters, elderly ICH patients comprised worse functional outcome at three months (adjusted odds ratio (aOR) in VKA-ICH: 1.49 (1.21–1.84); p < 0.001; NOAC-ICH: 2.01 (0.95–4.26); p = 0.069; non-OAC-ICH: 3.54 (2.50–5.03); p < 0.001). Anticoagulation was significantly associated with worse functional outcome below the age of 70 years, (aOR: 2.38 (1.78–3.16); p < 0.001), but not in patients of ≥70 years (aOR: 1.21 (0.89–1.65); p = 0.217). The differences in initial ICH volume and extent of ICH enlargement between OAC-ICH and non-OAC-ICH gradually decreased with increasing patient age. Conclusions: As compared to elderly ICH-patients, in patients <70 years OAC-ICH showed worse clinical outcomes compared to non-OAC-ICH because of larger baseline ICH-volumes and extent of hematoma enlargement. Treatment strategies aiming at neutralizing altered coagulation should be aware of these findings. [ABSTRACT FROM AUTHOR]

Background and Purpose: The influence of chronic kidney disease (CKD) on functional outcome in intracerebral hemorrhage (ICH) is scarcely investigated and reported findings are conflicting mostly because of nonaccounting for imbalances. Aim of the present study was to determine the impact of CKD on functional long-term outcome in ICH-patients.Methods: In this observational cohort study of spontaneous ICH-patients admitted to our Department of Neurology between 2006 and 2015 we investigated retrospectively as primary outcome the dichotomized functional status (modified-Rankin-Scale = 0-3-versus-4-6) at 12 months according to renal function (CKD versus non-CKD), including categorial estimates of the glomerular filtration rate subanalyses. Confounding was addressed by propensity-score(ps)-matching and adjusted multivariable regression analyses.Results: We identified 1076 eligible ICH-patients, of which 131 (12.2%) suffered from CKD on hospital admission. Confounders associated with CKD consisted of hypertension (P = .023), Diabetes mellitus (P = .001), prior ischemic stroke and/or transitory ischemic attack (TIA) (P = .021), congestive heart failure (P < .01), impaired liver function (P < .01), antiplatelet therapy (P = .01), poorer premorbid functional status (P < .01), and deep ICH-location (P = .006). After balancing for confounding, patients with CKD showed a significantly decreased rate of favorable functional outcome at 12 months (CKD:29 of 111(26.1%)-versus-non-CKD:78 of 206 (37.9%); P = .035). Subanalyses showed that stages of CKD were evenly associated with mortality at 12 months (GFR category G3a, OR:2.811; CI (1.130-6.994); P = .026; GFR category G3b, OR:1.874; CI (.694-5.058); P = .215; GFR category G4, OR:10.316; CI (1.976-53.856); P = .006; GFR category G5, OR:8.989; CI (1.900-42.518); P = .006).Conclusions: As compared to ICH-patients without CKD, those with CKD show increased rates of mortality and worse functional outcomes even after statistical correction for imbalanced baseline characteritsics. This finding is presumably linked to comorbidity and warrants further investigation in prospective studies. [ABSTRACT FROM AUTHOR]
