[The reason of the unfavourable life expectancy of patients with chronic kidney disease (CKD) is not only the development of end-stage renal failure but the frequent appearance of cardiovascular diseases (CVD). Chronic kidney damage itself is a cardiovascular risk state and the occurrence of CVD/associated diseases is significantly higher in chronic kidney failure. Beside risk stratification and valid treatment of CVD (hypertension, diabetes mellitus, ischemic heart disease e.g.) we and the international nephrological community have left the cerebrovascular diseases of CKD patients out of consideration. However, up to 50% of patients suffering a stroke will die immediately, only 10% of stroke survivors can continue his/her profession, but the others will be permanently disabled. High blood pressure is a strong predictor of stroke and of other CVD in most of the patients. In stroke risk reduction it is particularly important to reach the target blood pressure values. The main object of the “Live under 140/90 mmHg” programme of the Hungarian Society of Hypertension is to familiarize with target blood pressure itself and how to reach target blood pressure. In 2010, prevention, early diagnosis and management of stroke are the most important challenges of this programme (The Brain Control Programme). We think it is advisable to prepare and publish a clinical practice guideline in collaboration with stroke societies which is similar to the guidelines of international societies and of the Hungarian Society of Stroke but specific for CKD patients. This guideline would help to give a uniform, up-to-date treatment for the cerebrovascular diseases of CKD patients.]

[Author analyses the scientific results of his own clinical research work by evaluating his product in a „traditional way”, and only after then supplemented by scientometric data (citedness). From the 148 articles which has been published in foreign language (mostly in English) in abroad, 10 was grouped into the category of “new procedure/ recognition”, 40 into “original data/significant new statement”, and 98 into “new observation (statement) in a detailed question”. He has found close correlation between the values of the publications grouped by the traditional evaluation and the corresponding numbers of citations. Author discusses in the light of his own data the evaluating role of citedness with the hope to help by this motivated young scholars to plan their own future.]

[In chronic kidney disease (CKD) patients the high risk for cardiovascular events represents the major cause for morbidity and mortality. Stroke is the third most common manifestation of cardiovascular diseases and cause of death. The risk of cerebrovascular diseases persists in CKD patient in predialysis increases by 1.5-3 times whereas in patients on dialysis is increases by 4-10 times. The combination of classical cardiovascular risk factors and the pathomechanisms present in CKD and activated by dialysis treatment may explain the increased risk. The outcome of stroke is more severe in CKD, than in other populations. There are only a few data regarding early identification, primary and secondary prevention. and proper treatment of stroke in CKD patients with and without dialysis. In this review we summarize the diagnostic and treatment strategies that are based on the existing state of knowledge. However, additional studies are needed to address the poor prognosis through early identification of risk developing potential preventions and treatments of stroke in CKD.]

[Stroke is the third most frequent cause of death and the most important cause of disability and dependency worldwide. There are marked differences in the incidence, prevalence and mortality between the populations of Eastern and Western Europe. In Hungary, between 1998-2003, the incidence of stroke was 1,5-2 times higher than in the Western part of the continent. The early recognition of signs and symptoms of TIA and stroke and the urgent transportation of the patient to neurology, preferably to the nearest stroke-center are the key points of successful treatment, reduction of consequences and increased survival. The “time is brain” concept means that the management of TIA/stroke patients should be considered as emergency. This review briefly summarizes the epidemiology, key elements of the etiology, risk factors, up-to-dated diagnosis, primary and secondary prevention and treatment of TIA/stroke to provide information regarding the development of this field targeting the optimal management of TIA/stroke patients.]

[Association between cyclothymic affective temperament and hypertension]


[Affective temperaments (cyclothymic, hypertymic, depressive, anxious, irritable) are stable parts of personality and after adolescent only their minor changes are detectable. Their connections with psychopathology is well-described; depressive temperament plays role in major depression, cyclothymic temperament in bipolar II disorder, while hyperthymic temperament in bipolar I disorder. Moreover, scientific data of the last decade suggest, that affective temperaments are also associated with somatic diseases. Cyclothymic temperament is supposed to have the closest connection with hypertension. The prevalence of hypertension is higher parallel with the presence of dominant cyclothymic affective temperament and in this condition the frequency of cardiovascular complications in hypertensive patients was also described to be higher. In chronic hypertensive patients cyclothymic temperament score is positively associated with systolic blood pressure and in women with the earlier development of hypertension. The background of these associations is probably based on the more prevalent presence of common risk factors (smoking, obesity, alcoholism) with more pronounced cyclothymic temperament. The scientific importance of the research of the associations of personality traits including affective temperaments with somatic disorders can help in the identification of higher risk patient subgroups.]

Hyperhomocysteinemia in female migraineurs of childbearing ages


Background and purpose - Migraine is a risk factor for ischemic stroke in women of childbearing ages. Previous researches revealed a higher prevalence of hyperhomocysteinemia in migraineurs. Possible differences on the frequencies of hyperhomocysteinemia between migraine with aura and migraine without aura could contribute the established variances in stroke risk between these migraine types. Therefore, we aimed to search if the frequency of hyperhomocysteinemia was different between these subtypes of migraine or not. Methods - We analyzed the findings of serum homocysteine levels in female migraineurs of 16-49 years old who admitted to our outpatient clinic. Results - Homocysteine level was elevated in 13.3% of study population. There were not any significant differences on median serum homocysteine levels between migraine with aura (8.0 mikromol/L) and without aura (8.5 mikromol/L). (p=0.426) The frequencies of hyperhomocysteinemia were also similar (9.1% versus 16.7%, respectively; p=0.373). Correlation analyses did not reveal any linear correlation between ages and homocysteine levels either in group of migraine with aura or in group of migraine without aura (p=0.417 and p=0.647, respectively). Similarly, any linear correlation between disease ages and homocysteine levels either in group of migraine with aura or in group of migraine without aura was not detected (p=0.359 and p=0.849, respectively). Conclusion - The median serum homocysteine levels and the frequencies of hyperhomocysteinemia are similar between migraine with aura and without aura in women of childbearing ages. Therefore, the variances on stroke risk ratios between these types of migraine are probably not originated from the differences of serum homocysteine status.

[Treatment of hypertension in kidney transplant patients]


[Most of the renal transplant recipients suffer from hypertension. Hypertension substantially contributes to the high cardiovascular mortality in this population. The recommendation of the Hungarian Society of Hypertension and the international guidelines suggest to achieve less than 130/80 mmHg as target blood pressure in these patients. Several factors may be in the background of hypertension after kidney transplantation, which can be summarized as factors from the recipient-side, the donorside and factors provoked by transplantation itself. In most of the cases early after transplantation high doses of immunosuppressive drugs (especially calcineurin inhibitors and steroids) are responsible for the increased blood pressure. There are some further special methods apart from the general recommendations which are needed during the examination of hypertension of kidney transplant patients: e.g. measurement of blood trough-level of immunosuppressive drugs, investigation of bone-mineral disorder, screening for the level and causes of anaemia, check-up of the renal graft circulation. Kidney transplant patients suffering from hypertension usually need more than two antihypertensive drugs beyond the use of non-pharmaceutical antihypertensive methods. In the early posttransplantation period calcium channel blockers are preferred antihypertensive medications, because they counterbalance the vasoconstrictive effect of calcineurin inhibitors. The administration of renin-angiotensin-aldosterone inhibitors are rather suggested after the stabilization of renal function (from the 1-3 months posttransplantation). When designing antihypertensive strategy, comorbidities and special factors should be regarded as well, especially volume overload, proteinuria, allograft function (GFR), diabetes, other cardiovascular risk factors, previous cardiovascular events. The setup of an individual therapeutical strategy is advised in view of all these factors, which is different according to the timing after transplantation: the perioperative, the early postoperative phases and from 1-3 months after transplantation have special focuses.]

[The incidence of coronary heart disease in women rises sharply in the years following menopause. Hormone replacement therapy involves the administration of oestrogen, which provides postmenopausal symptom relief and reverses the changes in calcium and lipid metabolism. Moreover, oestrogen is also postulated to engage multiple mechanisms that defend against hypertension. Early observations suggested that postmenopausal women treated with hormone replacement therapy have significantly reduced cardiovascular risk. However, the results of primary and secondary prevention randomized clinical trials confirmed an increased cardiovascular risk rather than a beneficial effect of hormone replacement therapy in highrisk women. Controversy between results of observational and randomized clinical trials may partly be due to the unexplored genetic background. The authors summarize the effects of oestrogen on lipids, inflammation, haemostatic parameters, blood pressure and vascular wall. Genetic factors that modulate the effect of oestrogen as well as current recommendations on hormone replacement therapy after menopause in high risk women are also presented.]

[Carvedilol therapy in hypertension]


[Author analyzed the properties and antihypertensive effect of one of the best beta blockers with vasodilative effects, the carvedilol on the base of the Hungarian and international literature . Author deals with this issue for many years and he presented his own experience. The beta blockers could never be missed on therapy of the endemic hypertension. They are equivalent to other drug family. This played a big role , that the new , strong beta-1 selective and -- especially 3. generation beta blockers (carvedilol and nebivolol) - came to the fore in the therapy of hypertension compared with conventional beta blockers. The carvedilol has many beneficial properties, as vasodilatation, antioxidant effect, beneficial effect on the vascular stiffness, regression of left ventricular hypertrophy, increasing coronary reserve. Carvedilol is able to stable success on the therapy of hypertension as monotherapy or combination with the other drugs. In Hungary the physicians applied beta blockers about 30-35% in the treatment of hypertension.]
