Kopernika Abstract Hyperhomocysteinemia as a risk factor of stroke Since 1995 hyperhomocysteinemia (hyperHcy) is consider as a new, independent risk factor of vascular diseases. The level of Hcy was performed among 100 patients with ischaemic stroke confirmed by CT scan/MRI to aprove this hypothesis.The rutine lab tests were undertaken. The control group was consist of 20 healthy patients. In the first group the level of Hcy was statistical different and higher than in control. In 17 patients Hcy was elevated, the half of them were over 65 year-old. 30 % of patients had advanced arteriosclerotic process. In the patient with hyperHcy the prevalence of DM was higher, among the elderly with hyperHcy hyperlipidemia or IHD. Authors on the base of this results note that hyperHcy should be treated as the independent risk factor of ischaemic stroke and hyperHcy corelate with intensity of arteriosclerosis.

Extractions: due to folate deficiency Impact on haemostasis and vascular biology Liselotte M. Sabroe Ebbesen PDF This PhD dissertation was accepted by the Faculty of Health Sciences of the University of Aarhus, and defended on September 19, 2003. Dan Med Bull 2004;51:129. Hyperhomocysteinaemia (HH) has been identified as a risk factor for arterial and venous thrombosis in epidemiologic studies, although the pathogenesis is still largely unresolved. The aim was to evaluate the influence of HH on the whole blood coagulation profile (WBCP), the genetic regulation of blood cells and on balloon-induced neointima formation. Treatment of HH rats with the folate containing diet reversed the coagulation changes, as estimated by WBCP analyses and single coagulation factor functions. Indication of increased numbers of GpIIb/IIIa receptors was found in HH animals due to saturation kinetics as measured by WBCP following blockage of the platelet GpIIb/IIIa receptor. Up-regulation of uPAR, L-, E- and P-selectins was found and may contribute to increased tethering, rolling of leukocytes and migration of these to the vessel wall. A reduced amount of neointima was found in HH animals following endothelial cell denudation. This may be due to a reduced methylation capacity related to the severeness of folate depletion in experiment 1 animals.
Extractions: Elevated homocysteine is widely regarded as an independent risk factor for macrovascular disease, particularly in patients with type 2 diabetes (1). The increased prevalence of macroangopathy in type 2 diabetes is further demonstrated by Buysschaert et al. [2]. The authors found a significant increase in the prevalence of macroangiopathy in type 2 diabetic patients with hyperhomocysteinemia. Their data, however, should not be overinterpreted because the etiological role of homocysteine in atherosclerosis in the presence of macroangiopathy is far from clear [3]. First, the metabolism of homocysteine is altered for a period of several days following acute ischemic events, such as myocardial infarction [4] and stroke [5], as a result of an increased release from damaged tissues. This is caused by methylation of DNA, RNA, and various proteins, leading to an increase in S-adenosylhomocysteine and subsequently to increased homocysteine production [3]. Furthermore, nephropathy may reduce homocysteine clearance in type 2 diabetic patients. To our knowledge, there are no published studies examining the time course of homocysteine concentrations following acute ischemia, which may be silent. Hence, assessing homocysteine levels in patients with preexistent macroangiopathy may produce misleading results. This may in part account for the conflicting results regarding the association of homocysteine levels with insulin resistance that have been reported in various studies [6].
Extractions: We thank Chan et al. [1] for their interest in our work [2] and their relevant comments. We agree that there is still much to be learned about the relationship between homocysteine and atherosclerosis, as was recently stressed by Christen et al. [3]. We also agree that homocysteine metabolism is altered for a few days after acute ischemic events, as reported by Egerton et al. [4] and Lindgren et al. [5]. Therefore, patients with acute cardiovascular events were excluded from our analysis and could not interfere with the interpretation of our results. Chan et al. [1] pertinently mention the role of fibrates and metformin as potential confounders of homocysteine concentrations. Our data in type 2 diabetic patients confirm that fibrates significantly increased homocysteine levels, whereas there was no influence from metformin treatment.

Samenvatting Hyperhomocysteinemia is een risicofactor voor trombose en herhaalde trombose. Verhoogde homocysteine spiegels kunnen genormaliseerd worden met behulp van de B-vitamines foliumzuur, B6 en B12. In de huidige studie wordt het klinische effect van homocysteine verlagende therapie onderzocht, hetgeen nog nooit is bestudeerd. Hiervoor worden ongeveer 5000 patiënten met trombose op hun homocysteine gehalte in bloed gescreend en vervolgens wordt met de hyperhomocysteinemische patiënten een dubbel-blinde gerandomiseerde placebo-gecontroleerde studie uitgevoerd. Het eindpunt is herhaling van de trombose. Samenvatting-Eng Hyperhomocysteinemia is a risk factor for thrombosis and recurrent thrombosis. Elevated homocysteine levels can be normalised by the B-vitamins folate, B6 and B12. In the present study the clinical effect of homocysteine-lowering therapy is studied (has not been performed before). About 5000 patients with thrombosis will be screened for their homocysteine levels in blood. Those with elevated homocysteine will enter a double-blind randomised placebo-controlled study with end-point recurrent thrombosis. Looptijd Status afgesloten Betrokken organisaties
