Influence of time to admission to a comprehensive stroke centre on the outcome of patients with intracerebral haemorrhage.

ABSTRACT: IntroductionIn patients with spontaneous intracerebral haemorrhage, it is uncertain if diagnostic and therapeutic measures are time-sensitive on their impact on the outcome. We sought to determine the influence of the time to admission to a comprehensive stroke centre on the outcome of patients with acute intracerebral haemorrhage.Patients and methodsWe studied a prospective database of consecutive patients with intracerebral haemorrhage attended at two comprehensive stroke centres (2005–2017). We excluded patients with an unwitnessed time of onset of the intracerebral haemorrhage, or previous modified Rankin Scale >3 or in those in whom withdrawal of life-sustaining interventions were decided <24?h from admission. We recorded the time from the intracerebral haemorrhage onset to admission, demographic, clinical, radiological data, the functional outcome (favourable when modified Rankin Scale ?3) and mortality at 90 days. We conducted a propensity score-matching analysis to evaluate functional outcome and mortality.ResultsWe included 487 patients (mean age 72.3?±?13.9?years), and 53.2% were men. Compared to patients with an admission >110?min, patients who were admitted ?110?min were significantly younger, and had higher National Institutes of Health Stroke Scale scores. Moreover, patients admitted ?110?min were more likely to have basal ganglia intracerebral haemorrhage, and to show neurological deterioration. The propensity score groups were well matched. We did not find an association between time to admission and the favourable outcome (OR: 1.42 (95% CI: 0.93–2.16)) or mortality (OR: 0.64 (0.41–0.99)) at 90?days.ConclusionsOur results suggest that in patients with intracerebral haemorrhage and known symptom onset who are admitted to a comprehensive stroke centre, an early admission (?110?min) does not influence the outcome at 90?days.

Project description:Spontaneous intracerebral haemorrhage (SICH) has emerged as one of the most devastating forms of stroke in recent decades. This disease is noted to carry a 30-day mortality rate of approximately 45%. An increasing number of studies have implicated a complex immune-mediated and inflammation-mediated cascade of responses in the pathophysiology of SICH and the resultant neurologic outcome. Several clinical studies have demonstrated an association between inflammatory markers and outcome in patients with SICH. However, the exact relationship between serum biomarkers and functional outcomes amongst survivors has not been clearly elucidated. This study aimed to evaluate the changes in peripheral leukocyte count (WBC count) and C-reactive protein (CRP) levels in patients with SICH and to correlate these findings with survival and functional outcome.A prospective, descriptive and correlational study was conducted at Sarawak General Hospital (SGH) over the span of two years (April 2013-April 2015). Patients aged between 30 years and 75 years with supratentorial intracerebral bleed secondary to uncontrolled hypertension were recruited in this study. Data pertaining to the demography, clinical and radiological parameters, peripheral WBC count and CRP levels were obtained. Mortality and functional outcomes were determined at 6 months post ictus. Patients were recruited following the fulfilment of exclusion and inclusion criteria, and all obtained data were analysed with the Statistical Package for Social Sciences (SPSS) for Windows version 21.0.A total of 60 patients with a mean age of 56 years were recruited in this study. We found that approximately 16 patients were less than or equal to 50 years old (26.7%) and that 44 patients belonged to the older age group of above 50 years (73.3%). The Glasgow Coma Scale (GCS) score on admission ranged from 9 to 14/15 with a median value of 11/15. The mean clot volume was 20.1 cm3. The GCS score on admission and clot volume were significantly associated with the Glasgow Outcome Scale (GOS) at 6 months and overall survival (P < 0.05). The elevated WBC count and CRP level on admission and at 72 hours post admission were significantly associated with GOS at 6 months and overall survival (P < 0.05). Thus, the GCS score, clot volume, WBC count and CRP levels on admission and at 72 hours post admission can be used to predict functional outcome at 6 months and overall survival in patients with SICH.We could conclude via this study that for patients with SICH, the main determinants or predictors of functional outcome at 6 months and overall survival were noted to be the GCS score on admission, clot size, WBC count and CRP levels on admission and at 72 hours post admission.

Project description:IntroductionFew proven therapies for intracerebral haemorrhage exist. Preliminary observational evidence suggests that sulphonylurea and metformin may be protective in ischaemic stroke. We assessed the association of pre-intracerebral haemorrhage sulphonylurea and metformin use on outcome in diabetic patients.MethodsWe merged datasets from the consecutive single-centre Helsinki ICH Study, the intracerebral haemorrhage arm of the Virtual International Stroke Trials Archive (VISTA-ICH) and the Royal Melbourne Hospital ICH Study. Logistic regression adjusting for known predictors of intracerebral haemorrhage outcome (age, sex, baseline Glasgow Coma Scale, National Institutes of Health Stroke Scale, intracerebral haemorrhage volume, infratentorial location, intraventricular extension, and pre-intracerebral haemorrhage warfarin use) estimated the association of metformin and sulphonylurea with all-cause 90-day mortality.ResultsFrom a dataset of 2404 consecutive intracerebral haemorrhage patients, we included 374 (16%) patients with diabetes. Of these, 113 (30%) died by 90 days. Metformin was used in 148 (40%) patients and sulphonylurea in 115 (31%) patients at intracerebral haemorrhage onset. After adjusting for baseline characteristics, metformin use was associated with lower 90-day mortality (OR 0.51; 95% CI 0.26-0.97; p?=?0.041) irrespective of whether the drug was continued or not during the admission, while sulphonylurea use was not associated with mortality (OR 0.96; 95% CI 0.49-1.88; p?=?0.906). Haematoma location or evacuation did not modify the association between metformin and mortality; neither did adding insulin use, baseline glucose and serum creatinine into the model (OR 0.50; 95% CI 0.25-0.99; p?=?0.047).ConclusionPre-intracerebral haemorrhage metformin use was associated with improved outcome in diabetic intracerebral haemorrhage patients. Our results generate hypotheses which after further validation could be tested in clinical trials.

Project description:Late seizures after intracerebral haemorrhage occur after the initial acute haemorrhagic insult subsides, and represent one of its most feared long-term sequelae. Both susceptibility to late seizures and their functional impact remain poorly characterized. We sought to: (i) compare patients with new-onset late seizures (i.e. delayed seizures), with those who experienced a recurrent late seizure following an immediately post-haemorrhagic seizure; and (ii) investigate the effect of late seizures on long-term functional performance after intracerebral haemorrhage. We performed prospective longitudinal follow-up of consecutive intracerebral haemorrhage survivors presenting to a single tertiary care centre. We tested for association with seizures the following neuroimaging and genetic markers of cerebral small vessel disease: APOE variants ?2/?4, computer tomography-defined white matter disease, magnetic resonance imaging-defined white matter hyperintensities volume and cerebral microbleeds. Cognitive performance was measured using the Modified Telephone Interview for Cognitive Status, and functional performance using structured questionnaires obtained every 6 months. We performed time-to-event analysis using separate Cox models for risk to develop delayed and recurrent seizures, as well as for functional decline risk (mortality, incident dementia, and loss of functional independence) after intracerebral haemorrhage. A total of 872 survivors of intracerebral haemorrhage were enrolled and followed for a median of 3.9 years. Early seizure developed in 86 patients, 42 of whom went on to experience recurrent seizures. Admission Glasgow Coma Scale, increasing haematoma volume and cortical involvement were associated with recurrent seizure risk (all P < 0.01). Recurrent seizures were not associated with long-term functional outcome (P = 0.67). Delayed seizures occurred in 37 patients, corresponding to an estimated incidence of 0.8% per year (95% confidence interval 0.5-1.2%). Factors associated with delayed seizures included cortical involvement on index haemorrhage (hazard ratio 1.63, P = 0.036), pre-haemorrhage dementia (hazard ratio 1.36, P = 0.044), history of multiple prior lobar haemorrhages (hazard ratio 2.50, P = 0.038), exclusively lobar microbleeds (hazard ratio 2.22, P = 0.008) and presence of ? 1 APOE ?4 copies (hazard ratio 1.95, P = 0.020). Delayed seizures were associated with worse long-term functional outcome (hazard ratio 1.83, P = 0.005), but the association was removed by adjusting for neuroimaging and genetic markers of cerebral small vessel disease. Delayed seizures after intracerebral haemorrhage are associated with different risk factors, when compared to recurrent seizures. They are also associated with worse functional outcome, but this finding appears to be related to underlying small vessel disease. Further investigations into the connections between small vessel disease and delayed seizures are warranted.
