Acute cerebral ischemia triggers local and systemic immune response. The aims of this project was to assess the blood serum concentration of the markers of inflammation and markers of the blood brain barrier damage on the first day of ischemic stroke, and the mutual correlations between these marker levels. Methods Our prospective study included 138 patients with first-in-life stroke, who were analyzed according to: plasma concentration of the following markers on the first day of stroke: Il-2 and IL-6, S100B, TNF alfa, GRN, NSE, uPA, VEGF, BDNF, CRP, leucocyte and thrombocyte counts; their neurological status on the first day of stroke (NIHSS) and their functional status at 30 days following stroke (mRS). Result The study included 138 patients with mean age: 73.11 ± 11.48 [36-103]. Patients with a higher score on the NIHSS than those obtaining lower scores showed significantly higher concentrations of TNF-alpha, WBC, CRP, NSE, IL-6 and S100B. Patients with a higher score on the mRS than those obtaining lower scores showed significantly higher concentrations of WBC, CRP, GRN, IL-6, S100B. Factors with an independent influence on the neurological status on the first day of stroke were: sex, WBC, PLT, CRP, S100B and IL-6 levels. Atrial fibrillation, leukocyte count, CRP, NSA, uPA, interleukin 6 and S100B showed an independent impact on the functional status on the 30th day of stroke. Patients with symptomatic atherosclerosis of carotid/cerebral and/or coronary arteries, as compared to others, were older (p= 0.003) and had higher levels of CRP, Il-6, and S100B. In each case, the differences were statistically significant. Conclusions The concentration of Il-6 and S100B on the first day of stroke are significant for both the neurological status and the functional status in the acute period of the disease. Increased CRP and leukocyte count are associated with a worse prognosis regarding the course of acute stroke. The expression of pro-inflammatory agents and markers of blood-brain barrier damage in the acute phase of stroke is more prominent in patients with symptomatic atherosclerosis than in patients with no clinical features of atherosclerosis.
Background: An increase in the troponin I (TnI) level is a marker of myocardial damage in acute coronary syndromes (ACS) and other conditions. According to the latest reports, an increase in the concentration of TnI in the acute phase of stroke relates to 1-34% of patients. The aim of this study was to evaluate the prevalence of elevated TnI concentration in patients with acute first-ever stroke and to examine its significance for the prediction of post-stroke disability degree and death within 30 days of stroke. An additional aim of the study was to compare the anatomic location of stroke in patients with normal and elevated TnI concentrations on the 1st day of stroke. Methods: Patients (M/F: 609/459; mean age 72 ± 11) with stroke numbering 1,068 were included in the prospective study. Their neurological deficit (National Institutes of Health Stroke Scale), TnI concentration (normal range ≤0.014 ng/ml), creatine kinase and ECG were examined on the 1st day of stroke. A follow-up and ECG were performed one day later in patients with abnormal TnI. The anatomical location of stroke (the right and left hemispheres and the brain stem) was compared in patients with normal and elevated TnI concentrations on the first day of stroke. The patients' functioning status was assessed using the by modified Rankin Scale (mRS) on the 30th day, and mortality was assessed within 30 days. The analysis was performed using a single and multi-factorial method of non-linear estimation for logistic regression in order to identify the independent factors for post-stroke disability at 4-6 points on the mRS on the 30th day following the onset and for death within 30 days of stroke in relation to the entire study group. The relative risk of a 4-6 point scoring on the mRS and of death among patients with abnormal TnI concentrations was also assessed. Results: Abnormal TnI concentration during stroke was observed in 9.73% of patients. The functioning status (mRS) of patients with elevated TnI was significantly worse 30 days post stroke as compared to patients with normal TnI concentration. Stroke was significantly more frequent in the right-hemisphere in patients with elevated TnI and no ischaemic changes in the ECG. For patients with ACS Tn+ during stroke, the mortality within 30 days after stroke was significantly more frequent than for patients without ACS Tn+. The abnormal TnI level neurological status on the 1st day of stroke and age were independent mortality factors within 30 days following stroke. Elevated TnI concentration, hypertension and neurological status on the 1st day of stroke were independent factors for post-stroke disability. Conclusions: Elevated TnI concentration occurs in 1/10 of patients with acute ischaemic stroke. It is connected with an unfavourable course of stroke leading to a significant disability and less independence in their everyday functioning. The right hemisphere is the most common site of stroke accompanied by elevated concentration of troponin in patients with no ischaemic changes in the electrocardiogra...
studies, large international registries, and postmortem studies. [4][5][6][7][8] Polyvascular atherosclerosis in patients with single or multifocal clinical manifestations is associated with unfavorable clinical outcomes. [4][5][6]9 Atherosclerotic lesions in the carotid arteries and the thickness of the intima -media complex are recognized predictors of cardiovascular events in patients with symptomatic or asymptomatic ischemic heart disease and of complications during coronary angiography and coronary artery bypass graft (CABG) surgery. 3,10 -13 IntroductIon Atherosclerosis is a systemic arterial disease; however, the mechanisms underlying the formation, development, and destabilization of concomitant lesions observed in arteries of various calibers and varying reactivity parameters remain unclear. 1-3The involvement of arteries from different vascular areas indicates a significant burden of the atherosclerotic process, even if patients have never experienced any clinical symptoms of atherosclerosis. The coexistence of atherosclerosis in the coronary arteries, carotid arteries, and other vascular territories has been proven in clinical
Our results can help harmonize standards for MT in Poland according to international guidelines.
Background The distribution of risk factors for stroke is related to gender and age. The main objective of study was to determine the type and frequency of stroke risk factors in patients with first-in-life stroke before the age of 50. Methods Our study included patients under the age of 50 with first-in-life stroke. The following data obtained from all participants were analyzed: a neuroimaging of the head, wide panel of blood tests, electrocardiogram, transesophageal echocardiography, ultrasound of the carotid/cerebral arteries. 24-hour ECG monitoring and angio-MRI of head were performed in most patients. Results One hundred and eighty-four patients were qualified into the study; mean age - 39 years (female 45%). The female gender was significantly more often associated with diabetes, carotid/cerebral artery stenosis, myocardial infarction, cardiomyopathy and risk factors associated with lifestyle. More than half of the patients presented at least two risk stroke factors. The most frequent categories of risk factors were related to arteries and metabolic diseases. Vascular risk factors were among the most frequent in individual age categories. Hereditary stroke-burden was significant in the patient before the age of 20.15% of the patients haven't got known stroke risk factor. Conclusions Angiopathy is the most common risk factor for stroke at a young age. More than half of the patients with stroke at a young age have at least two independent risk factors for stroke. In the first two decades of life, the most frequent risk factors for stroke are heart diseases; arterial diseases play a dominant role in the consecutive three decades.
