Cím:Hemostasis biomarkers in the prognosis of non-traumatic intracerebral hemorrhage / T. Arokszallasi, Z. Bagoly, K. Fekete, I. Fekete, I. Szegedi, M. Andrejkovics, J. Toth, L. Csiba
Dátum:2019
Megjegyzések:Background and Aims: Non-traumatic intracerebral hemorrhage (ICH) accounts for 10?15% of all strokes and results in higher rate of mortality as compared to ischemic strokes. In the IRONHEART study we aimed to find potential hemostasis biomarkers with prognostic value in patients with ICH. Methods: In this prospective, observational study, 183 acute stroke patients and 140 healthy controls were included. Patients were grouped: 51 primary ICH patients (PICH), 118 acute ischemic stroke patients who underwent thrombolysis without hemorrhagic events (AIS), 13 patients with AIS who suffered hemorrhagic complications after intravenous thrombolysis (AIS-ICH). On admission, CT angiography, detailed clinical and laboratory investigations were performed. The following hemostasis measurements were carried out from blood samples: hemostasis screening tests, von Willebrand factor (VWF) antigen, factor XIII (FXIII), plasminogen and a2 antiplasmin activity, D-dimer. Patients were followed for 90 days, long term outcomes were defined using the modified Rankin Scale. Results: VWF level was significantly higher in all patient groups as compared to controls. VWF levels were significantly higher in patients with worse long-term outcomes (mRS>3) in all patient cohorts. FXIII activity was significantly elevated in the PICH group as compared to controls and to both AIS groups. FXIII activity in the lowest quartile was associated with a significant risk of mortality in the PICH group (OR: 9.9; 95%CI:1.6- 61.6, p ? 0.015). Among fibrinolytic markers, only D-dimer showed association with worse long-term outcomes (mRS>3). Conclusions: VWF antigen, FXIII activity and D-dimer could serve as biomarkers of long-term outcomes in PICH patients.

Cím:Cochrane Report : a systematic review of mannitol therapy for acute ischemic Stroke and cerebral parenchymal Hemorrhage / Bereczki, D., Liu, M., do Prado, G. F., Fekete, I.
Dátum:2000
ISSN:0039-2499
Megjegyzések:Background?Mannitol was reported to decrease cerebral edema associated with tissue damage and is used to treat acute stroke in many countries.Summary of Review?We tested whether there is any evidence from unconfounded randomized clinical trials that treatment with mannitol reduces short- and long-term case fatality and dependency if administered after ischemic stroke or cerebral parenchymal hemorrhage. Trials were identified by the standard search strategy of the Cochrane Collaboration Stroke Review Group. A supplementary MEDLINE search was performed, and the Chinese Stroke Trials Register and the Latin-American databank LILACS were checked. A search was performed of master's and PhD degree theses in the databank of Sao Paulo University and in abstracts of medical congresses on neurology and neurosurgery during 1965?1997 in Brazil. Investigators were contacted for unpublished information. Only truly randomized unconfounded clinical trials were eligible for inclusion. Two of the reviewers independently extracted data from the trials. Data synthesis and analysis was performed with the use of the Cochrane Review Manager software (RevMan version 4.0.4).Conclusions?Only 1 trial fulfilled the inclusion criteria. The number of included patients was small, and the follow-up was short. Case fatality, the proportion of dependent patients, and side effects were not reported and were not available from the investigators. As a result of lack of appropriate randomized trials, currently no conclusion can be drawn on the effects of mannitol in acute stroke. The routine use of mannitol in all patients with acute stroke is not supported by evidence from randomized controlled clinical trials.

Cím:Mannitol use in acute stroke : case fatality at 30 days and 1 year / Bereczki D., Mihálka L., Szatmári S., Fekete K., Di Cesar D., Fülesdi B., Csiba L., Fekete I.
Dátum:2003
ISSN:0039-2499
Megjegyzések:BACKGROUND AND PURPOSE: Mannitol is used worldwide to treat acute stroke, although its efficacy and safety have not been proven by randomized trials.METHODS:In a tricenter, prospective study, we analyzed the 30-day and 1-year case fatality with respect to mannitol treatment status in 805 patients consecutively admitted within 72 hours of stroke onset. Confounding factors were compared between treated and nontreated patients.RESULTS:Two thirds of the patients received intravenous mannitol as part of their routine treatment (mean dose, 47+/-22 g/d; mean duration, 6+/-3 days). The case fatality was 25% versus 16% (P=0.006) at 30 days and 38% versus 25% (P<0.001) at 1 year in the-mannitol treated and nontreated groups, respectively. Mannitol treatment effect was adjusted for age, stroke severity, fever in the first 3 days, and aspirin treatment (for ischemic strokes) in logistic regression models. Depending on the factors entered into the model, either no effect or harm could be attributed to mannitol. When the analysis was restricted to those admitted within 24 hours (n=568), case fatality differed significantly only at 1 year (35% in treated and 26% in nontreated patients, P=0.044). Although the prognostic scores of the Scandinavian Neurological Stroke Scale were similar in treated and nontreated patients, both in ischemic and hemorrhagic strokes, the patient groups differed in several factors that might also have influenced survival.CONCLUSIONS:Based on the results of this study, no recommendations can be made on the use of mannitol in acute stroke, and properly randomized, controlled trials should be performed to come to a final conclusion.

Cím:The Debrecen Stroke Database : demographic characteristics, risk factors, stroke severity and outcome in 8088 consecutive hospitalised patients with acute cerebrovascular disease / Bereczki D., Mihalka L., Fekete I., Valikovics A., Csepany T., Fulesdi B., Bajko Z., Szekeres C., Fekete K., Csiba L.
Dátum:2009
Megjegyzések:High stroke mortality in central-eastern European countries might be due to higher stroke incidence, more severe strokes or less effective acute care than in countries with lower mortality rate. Hospital databases usually yield more detailed information on risk factors, stroke severity and short-term outcome than population-based registries. Patients and methods The Debrecen Stroke Database, data of 8088 consecutively hospitalised patients with acute cerebrovascular disease in a single stroke centre in East Hungary between October 1994 and December 2006, is analysed. Risk factors were recorded and stroke severity on admission was scored by the Mathew stroke scale. The modified Glasgow outcome scale was used to describe patient condition at discharge. Results Mean age was 68713 years, 11.4% had haemorrhagic stroke. The rate of hypertension on admission was 79% in men, and 84% in women, 40.3%of men and 19.8%of women were smokers, and 34% of all patients had a previous cerebrovascular disease in their history. Case fatality was 14.9%, and 43% had some disability at discharge. Outcome at discharge was worse with higher age, higher glucose, higher blood pressure, higher white cell count and erythrocyte sedimentation rate and more severe clinical signs on admission. In multivariate analysis admission blood pressure lost its significance in predicting outcome. Conclusions In this large Hungarian stroke unit database hypertension on admission, smoking and previous cerebrovascular disease were more frequent than in most western databases. These findings indicate major opportunities for more efficient stroke prevention in this and probably other eastern European countries.

Cím:Characteristics of 4 stroke scales for the detection of changes in clinical signs in the acute phase of stroke / Bessenyei, M., Fekete, I., Csiba, L., Bereczki, D.
Dátum:2001
ISSN:1052-3057
Megjegyzések:OBJECTIVES: Detection of minor changes in clinical signs of stroke may be of interest when evaluating treatment interventions. This study analyzes the internal structure of four frequently used stroke scales and compares them for their sensitivity to detect changes in neurologic signs in the first week after acute stroke.METHODS:A cohort of 77 hospitalized acute stroke patients was scored by the Mathew, the National Institutes of Health (NIH), the Scandinavian, and the Orgogozo scales within 48 hours of hospital admission and again 7 days later.RESULTS:Scores on different scales correlated well with each other (range of absolute value of Spearman R, .82-.91; P <.001 in all comparisons). Scales reflected significant changes from entry to reexamination: P = .0013 for the Scandinavian scale (P = .004 for prognostic and P = .009 for long-term items, respectively); P = .00009 for the Orgogozo scale; P = .000007 for the Mathew scale; and P < .000001 for the NIH scale. This difference in sensitivity coincided with the number of factors extracted by principal component analysis: higher sensitivity of a scale was associated with a larger number of factors. Initial scores differed significantly among patients who were discharged, patients who died, and patients who remained hospitalized 7 days after the first examination (Kruskal-Wallis ANOVA, P < .01 for all scales).CONCLUSIONS:There are considerable differences in the internal structure of the different scales as reflected by the different number of factors extracted from the scale items. The application of the NIH scale is recommended for the most sensitive detection of changes in stroke signs.

Cím:Predictors of long-term outcome in patients with basilar artery occlusion : a single center study / K. Fekete, J. Toth, H. Mate, M. Sandor, H. Toth, L. Csiba, I. Fekete
Dátum:2019
Megjegyzések:Background and Aims: Basilar artery occlusion (BAO) is a fatal disease despite recanalization techniques and limited data is available of the factors predicting outcome. Methods: Data of 100 patients treated with BAO was collected prospectively between 2004 and 2018. Risk factors, neurological status, outcome (case fatality, 3-months-mRS, one-year-survival); cranial CT (posterior circulation ASPECT score), result of CT angiography; and the treatment modality was given. Results: Average age was 64.9 13.7 years, 54% male. The most remarkable risk factor was previous stroke (29%), 55% of it vertebrobasilar (58% mortality). The onset to treatment time was 4.23 2.85 hours. The pc-ASPECT score was 10 in 67%, 7 points 33%. BAO was in the proximal part in 17%, in half in 20%, total in 21% and only the top in 42%; respectively within its group the mortality was 53%, 45%, 62%, 38%. Intravenous thrombolysis happened in 43%, intraarterial in 27%, combined therapy in 18% and 12% was treated conservatively. Case fatality within the treatment group was respectively: 48.8%, 55.5%, 33.3%, and 66.6% (p ? 0.8). Symptomatic haemorrhage was not different among the recanalization groups (p ? 0.83). Total or partial recanalization was achieved in 39%. There was a favourable trend in the recanalization rate of intraarterial and combined groups (p ? 0.4). At 3 months 23% had mRS 0?2, 3?5 42%, 58% were dead. At one year 26% was alive. Conclusions: The top occlusion of the BA, combined therapy may influence favourably the outcome. Among the risk factors previous VB stroke has a high impact. Trial registration number: N/A

Dátum:2015
ISSN:1052-3057 1532-8511
Megjegyzések:Background: This prospective single-center study aimed to identify features determininglong-term outcome after thrombolysis in a Central European stroke population.Methods: Between 1 January, 2004, and 31 December, 2010, 415 patients weretreated with recombinant tissue plasminogen activator at the Department ofNeurology, University of Debrecen. Stroke severity by the National Institute ofHealth Stroke Scale score (NIHSSS) and imaging findings by the Alberta Stroke ProgrammeEarly Computed Tomography score (ASPECTS) were evaluated on admissionand 1 day later. The modified Rankin Scale (mRS) at 3 months and case fatalityat 1 year were evaluated. Independent predictors of outcome were identified bymultivariate testing. Results: Data of 369 patients were analyzed. Median NIHSSSwas 12 (interquartile range [IQR], 8-17) on admission and 10 (IQR, 5-16) at 24 hours.Arterial occlusion was found in 55%. Symptomatic intracerebral hemorrhage (SICH)was detected in 3.8%. Outcome was significantly worse, and SICH was morefrequent in intra-arterially treated patients. At 3 months, one third of the patientswere independent (mRS #2), and 23% were dead. At 1 year 2 of 3 patients were alive.Significant independent predictors of disability at 3 months were 24-hour NIHSSS,admission ASPECTS, admission glucose level, and treatment modality. Only the24-hour NIHSSS was a significant predictor of case fatality at 1 year. Conclusions:Although short-term outcome was similar, the 3-month and 1-year outcomes wereworse than data from previous reports. A more efficient health care program shouldbe implemented after stroke to maintain the favorable effect of thrombolysis in thelong term.

Cím:Effects of carbon dioxide inhalation on cerebral blood flow and oxygen tissue level in spontaneously hypertensive rabbits / Katalin Hegedűs, István Fekete, László Molnár
Dátum:1992
ISSN:0039-2499
Megjegyzések:BACKGROUND AND PURPOSE:Because previous studies have yielded conflicting results, this study was designed to investigate the efficiency of cerebrovascular reactivity to carbon dioxide in hypertension associated with moderate diffuse cerebral ischemic lesions.METHODS:The effects of carbon dioxide inhalation on mean arterial blood pressure, heart and respiration rates, cerebral cortical blood flow, polarographically detected oxygen currents (oxygen availability), and cerebral electrical activity were compared in 14 spontaneously hypertensive and 16 normotensive rabbits anesthetized with urethane and alpha-chloralose. Blood flow was measured with the hydrogen clearance and thermal clearance methods.RESULTS:In the resting state the frequency of electrical activity shifted to slower components, the levels of oxygen availability and cerebral blood flow were lower (p less than 0.01), and the ratio of the two latter parameters was greater (p less than 0.01) in hypertensive rabbits than in normotensive animals. Carbon dioxide inhalation induced more marked increases in cerebral blood flow, respiration rate, and oxygen availability in hypertensive (p less than 0.01) than in normotensive (p less than 0.05) rabbits. The ratio of oxygen availability to cerebral blood flow decreased (p less than 0.01) in the former and did not change significantly in the latter group. The carbon dioxide-induced rise in blood flow was also slower and more protracted in hypertensive rabbits (p less than 0.01). Histological investigation revealed groups of neurons with ischemic changes in the cortex of the hypertensive rabbits.CONCLUSIONS:We suggest that in hypertensive rabbits the mild multiple ischemic lesions are the basis of functional disturbances, including reduced resting cerebral blood flow, greater oxygen tissue level, slower response to carbon dioxide, and greater vasodilatory capacity.
