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 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.

Background: The objective of this study was to evaluate the impact of weather factors on stroke parameters. Methods: This retrospective study analyzed the records of stroke patients concerning the influence of meteorological conditions and moon phases on stroke parameters. Results: The study group consisted of 402 patients aged between 20 and 102; women constituted 49.8% of the subjects. Ischaemic stroke was diagnosed in 90.5% of patients and hemorrhagic stroke was diagnosed in 9.5% of patients. The highest number of hospitalizations due to stroke was observed in January (48 events); the lowest number was observed in July (23 events). There was no statistically significant correlation between the meteorological parameters on the day of onset and the preceding day of stroke and the neurological status (NIHSS) of patients. Mean air temperature on the day of stroke and the day preceding stroke was significantly lower in the group of patients discharged with a very good functional status (≤2 points in modified Rankin scale (mRS)) compared to the patients with a bad functional status (>2 points in mRS); respectively: 7.98 ± 8.01 vs. 9.63 ± 7.78; p = 0.041 and 8.13 ± 7.72 vs. 9.70 ± 7.50; p = 0.048). Humidity above 75% on the day of stroke was found to be a factor for excellent functional state (RR 1.61; p = 0.016). The total anterior circulation infarcts (in comparison with stroke in the other localization) were more frequent (70%) during a third quarter moon (p = 0.011). The following parameters had a significant influence on the number of stroke cases in relation to autumn having the lowest number of onsets: mean temperature (OR 1.019 95% CI 1.014–1.024, p < 0.000), humidity (OR 1.028, CI 1.023–1.034, p < 0.0001), wind speed (OR 0.923, 95% CI 0.909–0.937, p < 0.0001), insolation (OR 0.885, 95% CI 0.869–0.902, p < 0.0001), precipitation (OR 0.914, 95% CI 0.884–0.946, p < 0.0001). Conclusion: Air humidity and air temperature on the day of stroke onset as well as air temperature on the day preceding stroke are important for the functional status of patients in the acute disease period. A combination of the following meteorological parameters: lowered mean temperature and low sunshine, high humidity and high wind speed all increase the risk of stroke during the winter period. High humidity combined with high precipitation, low wind speed and low sunshine in the autumn period are associated with the lowest stroke incidence risk. A possible relationship between phases of the moon and the incidence requires further investigation.

Oddział Neurologii z Pododdziałem Udarowym, Górnośląskie Centrum Medyczne, Katowice S t r e s z c z e n i eUstalenie właściwego, czyli skutecznego i bezpiecznego leczenia przeciwkrzepliwego stanowi często złożony, interdyscyplinarny problem. Terapia doustnymi antykoagulantami niebędącymi antagonistami witaminy K, preparatami bezpieczniejszymi i co najmniej tak skutecznymi jak warfaryna stwarza pewne możliwości, nie jest jednak pozbawiona ograniczeń i powikłań. W niniejszej pracy zaprezentowano przypadki pacjentek w wieku 45 i 86 lat, których leczenie wymagało szerokich działań ze strony zarówno neurologów, jak i kardiologów, a dobór odpowiedniej terapii antykoagulacyjnej był trudny. Słowa kluczowe: leczenie przeciwkrzepliwe, udar mózgu A b s t r a c tDetermining proper, i.e. effective and safe anticoagulant therapy is often complex interdisciplinary problem. New oral anticoagulants are safer and at least as effective as vitamin K antagonists. The therapy with those agents creates some opportunities; however, it is also associated with some limitations and complications. We present the cases of two patients aged 45 and 86 years whose treatment required extensive interventions by both neurologists and cardiologists and in whom the selection of the appropriate anticoagulant therapy was difficult.
