[Objectives: To evaluate a possible link between serum uric acid (SUA) levels, arterial stiffness and atherogenic index of plasma on one hand and renal function on the other and to test the role of SUA in the assessment of total cardiovascular risk. Materials and methods: We studied serum uric acid levels (SUA) in 1975 subjects included in SEPHAR II survey. We measured arterial stiffness parameters, calculated atherogenic index of plasma and estimated glomerular filtration rate (eGFR) by MDRD and CKD-EPI formulae and assessed total cardiovascular risk according to current ESH-ESC risk stratification chart. Results: The highest SUA values were recorded in subjects with grade III HT and were correlated with increased arterial stiffness and with increased atherogenic index of plasma. The lowest eGRF values, assessed by both MDRD and CKD-EPI, were observed among subjects with hyperuricemia and a significant indirect correlation between SUA and eGFR was evidenced. A proportional correlation between SUA values and total CV risk was also obtained. Conclusions: The study supports SUA implication in the pathogenesis of elevated blood pressure and the role of uric acid as a cardiovascular risk factor, particularly for the development of hypertension and renal disease.]

[Visualization of glomerular filtration in animals in vivo - significant filtration in afferent arteriola. Regulation of endothelial permeability]

ROSIVALL László

[Recently we have in vivo visualized glomerular filtration and fluid flow from the JGA portion of afferent arteriole into JGA using intravital multiphoton microscopy. Fluorescence of the extracellular fluid marker lucifer yellow appeared in the interstitium around the distal portion of afferent arteriole before the filtration into Bowman's capsule. In isolated microperfused JGA we demonstrated fluid movement from the glomerulus into the MD tubule. All these prove that there is a significant and dynamic fluid flow exists in the JGA. Angiotensin II similar to VEGF plays a role in regulation of permeability/fenestration formation. Angiotensin II acts through AT1 receptor and PV-1 protein synthesis.]

[Signaling pathways in renal fibrosis]

ROKONAY Réka, SZIKSZ Erna, LIPPAI Rita, PAP Domonkos, VERES-SZÉKELY Apor, REUSZ György, SZABÓ Attila, VANNAY Ádám

[Myofibroblasts are the main effector cells of tissue fibrosis in chronic kidney disease. These cells are the main source of collagen rich extracellular matrix in the fibrous tissue. Recent hypotheses suggest that pericytes are the major progenitors of myofibroblasts. Platelet derived growth factor, transforming growth factor β and Wingless/Int signaling pathways play important role in pericyte activation. There are experimental evidences that blocking this pathways inhibits tissue fibrosis, therefore they might be targets for the development of antifibrotic drugs in the future.]

[Local importance of Hantavirus infections in mirror of the latest virological, epidemiological and clinical results]

NÉMETH Viktória, OLDAL Miklós, SEBÕK Judit, WITTMANN István, JAKAB Ferenc

[Hantaviruses are widespread infectious agents carried by different rodent species. The majority of them belongs to viral zoonotic pathogens, sometimes causing severe human infections. Hantaviruses inflict hemorrhagic fever with renal syndrome in Eurasia and supposedly in Africa, and hantavirus cardio-pulmonary syndrome in the Americas. The relationship between the virus and its host species is a result of a several million year co-evolution. Although virus replication is most intense in the infected rodents' lungs, these animals do not develop disease, instead they carry and spread the pathogens throughout their lifetime by body fluids. In the majority of infections, the virus gets into the human body by vaporization of rodent body fluids or by direct contact. In Europe, Puumala (PUUV) and Dobrava-Belgrade (DOBV) hantaviruses are the most abundant hantaviral infectious agents. There are numerous studies described the presence of different genotipes of hantaviruses circulating in Hungary. Although the number of clinical and epidemiolgical studies are limited, the medical importance - especially in a high risk population - of these viruses are unqustionable. There are a variety of methods to identify hantaviral infections. Molecular biological methods (RT-PCR) - also enabling genotyping - and virus neutralization tests proved to be the most reliable tools. The latter technique requires virus culturing, which can only be carried out in high-containment laboratories.]

[Importance of Reynolds-score system on cardiovascular risk assessment]

MÓCZÁR Csaba

[The author summarizes knowledge about Reynolds risk assessment system based on data of references and own experiences. The first part of article is about how the results of study of pathogenesis of atherosclerosis were converted into new risk assessment systems. One result of this process is the Reynolds system wich is consisted of traditional riks factors, high sensitive C-reactive protein and the patients’ family medical history. He demonstrates essence of Reynolds system and process of it’s validity. The author deals with comparison of Reynolds system with other traditional risk assessment systems. The practical issues of application of Reynolds system are detailed in the conclusion of the article.]

[Association between cyclothymic affective temperament and hypertension]

NEMCSIK János, BATTA Dóra, KŐRÖSI Beáta, RIHMER Zoltán

[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.]

[The importance of assessing subclinical organ damage in risk prediction of hypertensive patients]

GODINA Gabriella, JÁRAI Zoltán

[As the cardiovascular risk influences the quality and intensity of blood pressure lowering therapy, the goal blood pressure values and the frequency of medical control of hypertensive patients, as well as global risk assessment has an important role in the management of hypertension. In the last couple of years many data have been accumulated showing the poor prognostic value of traditional cardiovascular risk factors. This is the reason why recent Hungarian and international guidelines on the management of hypertension advise the screening for subclinical organ damage. Our goal was to summarize the importance of subclinical organ damage by discussing recently published literature on this topic. An overview has been made on the markers of vascular subclinical damage, like carotid atherosclerosis proved with carotid ultrasonography, peripheral arterial disease assessed with ankle-brachial pressure index measurements and vascular rigidity defined with pulse wave velocity measurements. The prognostic values of myocardial hypertrophy assessed with ECG and/or echocardiography and renal damage proved with decreased estimated glomerular filtration rate and proteinuria are also discussed. Summing up what has been said so far, the assessment of subclinical organ damage has a role in cardiovascular risk prediction, however more randomized and prospective studies have to be performed to define the most suitable (i.e. the most reliable and the most cost-effective) markers for this purpose.]

[Update on diagnostics and therapy of the renal artery stenosis in 2010]

KOLOSSVÁRY Endre, FARKAS Katalin, KERKOVITS Lóránt, KISS István

[Results of epidemiological studies indicate the atherosclerotic renal artery stenosis is a common condition, thus development of its diagnostics and therapy has significant importance. Renal artery narrowing can cause hypertension, renal function decline, cardiac failure and the increased cardiovascular risk seriously affects survival perspective of the patients. The evolution of MR technology has a prominent role in renovascular diagnostics. Beyond the detection of arterial stenosis this technique is capable of the functional characterization of the stenosis and the detailed description of the regional kidney tissue damage. Based on the results of clinical studies the relevance of revascularization of the renal artery stenosis remains uncertain. The trials focusing on this issue show methodological imperfections. It remains to be elucidated whether these methodological problems will be tackled in the future based on the present information. This review focuses on the actual findings corresponding to these problems.]

[Diuretikumok hypertoniában - 2010]

BARNA István

[Diuretics (especially thiazide derivatives and indapamide that also has vasodilator efficacy) are considered as first line treatment in hypertension. They are particularly favourable in the treatment of overweight, elderly, isolated systolic hypertensive patients suffering from type 2 diabetes and metabolic syndrome or in mild renal and cardiac insufficiency. They can be ideally combined with other antihypertensive agents (primarily with angiotensin-converting enzyme inhibitors, angiotensin receptor blocking agents és béta-blockers). If hypertension is associated with left ventricular hypertrophy or stroke indapamide is the appropriate choice. In case of left ventricular dysfunction and heart failure thiazide and/or furosemide is the adequate option. Low dose diuretics have no clinically relevant side effects and reduce cardiac mortality to the same extent as other pharmaceutical interventions.]

[Cholesterol-lowering is not the Holy Grail, but neither is the work of the devil]

BAJNOK László

[Cholesterol-lowering statins are the most tested medications in respect of the effects and side-effects. Based on these, we can safely claim that most of the negative opinions about cholesterol-lowering are not realistic. It is not a panacea, but it is proven that around a 30% of cardio- and cerebrovascular risk reducation can be achieved by their regular taking, while the incidence of side effects and risks are at least one order of magnitude lower in each patient groups. For cholesterol, there is no “normal” lab threshold or low level, only “target values”, since the mean value in the general population is high in regard of atherosclerosis (the values measured at birth and among natural people can be considered normal). Let us appreciate the cholesterol- lowering medications because we do not have a large armamentarium!]
