INTRODUCTION Several studies have highlighted the role of interleukin-6 (IL-6) as an early signal of the inflammatory response following acute ischemic stroke. This study examines the potential advantage of employing high-sensitivity (hs)-IL-6 as a possible biomarker at the early stages of acute stroke for identifying an acute phase response and its(More)
BACKGROUND AND PURPOSE Identification of the subgroup of asymptomatic patients with severe internal carotid artery stenosis and high risk of stroke has important clinical implications. Cerebral vasomotor reactivity provides information regarding intracranial hemodynamic features and might have a prognostic value in predicting cerebrovascular ischemic(More)
BACKGROUND AND PURPOSE Prior studies have demonstrated that infections might precipitate ischemic strokes (IS), but the role of infection as a risk factor remains unclear. We conducted a case-control study to investigate this issue. METHODS Consecutive patients (n = 182) with acute IS were examined within 48 hours after admission to our center. A history(More)
To date there is no diagnostic biomarker for mild stroke, although elevation of inflammatory biomarkers has been reported at early stages. Previous studies implicated acetylcholinesterase (AChE) involvement in stroke, and circulating AChE activity reflects inflammatory response, since acetylcholine suppresses inflammation. Therefore, carriers of(More)
C-reactive protein (CRP) increases following an acute stroke/transient ischemic attack (TIA), but the increment level varies among patients. We analyzed CRP concentrations during an acute stroke/TIA in relation to the CRP gene -717A>G polymorphism. Six months following an acute ischemic stroke/TIA, basal concentrations of CRP were measured in 507 controls(More)
BACKGROUND Early biomarkers for survival in an acute ischaemic stroke/transient ischaemic attack might serve as a useful tool for the clinician. Several studies have highlighted the role of inflammatory biomarkers as an early signal for acute ischaemic stroke prognosis. AIMS This study examines the potential advantage of using high-sensitivity(More)
Increased fibrinogen concentration is a well known phenomenon following acute ischemic stroke. However, the natural course of this hyperfibrinogenemia is uncertain. We aimed to clarify whether it is of a transient or more persistent nature in patients who harbor an underlying morbid biology of atherothrombo-inflammation. Venous blood for fibrinogen(More)
OBJECTIVE To compare the recently introduced wide-range C-reactive protein (wr-CRP) with the widely used high-sensitivity Behring Dade method (hs-CRP) in acute stroke/transient ischemic attack (TIA) patients. MATERIALS AND METHODS A total of 119 consecutive patients admitted to a tertiary medical center with acute ischemic stroke/TIA were included in the(More)
BACKGROUND AND PURPOSE The alanine/valine (A/V) polymorphism at codon 677 of the 5,10 methylenetetrahydrofolate reductase (MTHFR) gene correlates with elevated levels of plasma homocysteine and with an increased risk of atherosclerotic cardiovascular disease. Our study was designed to assess the frequency of the A and V alleles in patients with asymptomatic(More)
BACKGROUND AND PURPOSE White matter changes (WMCs), or leukoaraiosis (LA), are associated with increased age, hypertension, diabetes mellitus, and history of stroke. Although several lines of evidence suggest a role of atherosclerosis in atherothrombotic vascular events, their involvement in LA remains to be determined. Our study examines this association(More)
