Hypertension and nephrology - 2010;14(04)

[Assessment of early atherosclerosis and decreased arterial elasticity to recognise the cardiovascular dysfunction in high-risk patients has gained importance in the past decade. Since 1990, more than 630 papers have been published in the adult and pediatric literature. Methods of early risk assessment in adults are well determined in international recommendations. The aim of the present work is to review the suggestions of the American Heart Association helping us to find the most appropriate method for the non invasive methods of cardiovascular assessment of young adults and children. Furthermore, multicentric studies should be conducted to create a Framingham like score system for pediatric patients, to render cardiovascular risk assessment much easier for the every day routine.]

[On the safety of angiotensin-receptor blockers - A new attack on this drug class]

FARSANG Csaba

[Up until now, angiotensin-receptor blockers have been considered to be the safest cardio-, cerebro-, reno- and vasculoprotective drugs. In a previous metaanalysis, ARBs were accused of increasing the risk of myocardial infarction, but a number of metaanalyses and randomised, controlled trials have disproved this hypothesis. In a recent metaanalysis, ARBs were associated with an increased risk of tumours. The author reviews this issue, discusses the flaws of the above metaanalysis and, on the basis of the most up-to-date data in the literature, expert opinions and official statements (FDA, EMA), concludes that members of this drug class should continue to be used according to their approved indications, which is supported by their cardio-, reno-, cerebro- and vasculoprotective effects demonstrated in a number of appropriate, large-scale clinical studies.]

[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.]

[Chlamydia pneumoniae in coronary arteries of young adults]

HORTOVÁNYI Eszter, ILLYÉS György, GLASZ Tibor, KULKA Janina, KÁDÁR Anna

[INTRODUCTION - An association of Chlamydia pneumoniae (C. pneumoniae) with coronary heart disease has been found with seroepidemiological methods. This organism was demonstrated in atheromatous plaques by electron microscopy, immunohistochemistry, and polymerase chain reaction. MATERIAL AND METHODS - To better understand the significance of the presence of C. pneumoniae in atheromatous plaques, we examined coronary artery segments from young adults (15-34 years) with and without atherosclerosis. 74 samples of left anterior descending artery were examined immunohistochemically for the presence of C. pneumoniae by the monoclonal antibody RR402. RESULTS - C. pneumoniae was identified in the atheroma in 11 of 17 cases (65%) and in preatheroma in 6 of 15 cases (40%), in fatty streak in 7 of 23 cases (30%) and in intimal thickening in 1 of 14 cases (7%). C. pneumoniae was not found in the intimal and medial layer of the normal-appearing coronary arteries. C. pneumoniae was detected in the adventitia in 51 cases (67%) of the coronary arteries: in the normal arteries and initial lesions in 27 of 42 cases (63%), and in the advanced lesions in 24 of 32 cases (75%). Correlation was observed between the C. pneumoniae positive cases and cigarette smoking. CONCLUSION - Our results suggest that C. pneumoniae may relate to the severity of atherosclerosis in the youth, thus may initiate atherosclerotic injury or facilitate its progression along with other risk factors.]

[New possibilities in treating hyperlipidemia]

CSÁSZÁR Albert

[In the fight against atherosclerosis, statin therapy is one of the most important elements. On the basis of data from the past few years the clinical introduction of a more effective statin is not expected, however, in order to improve cardiovascular prevention further development of agents that reduce LDL-cholesterol levels more effectively than currently used statins is warranted. The need for the development of new cholesterol-lowering therapeutic options is also supported by the existence of statin intolerance. The currently available combination therapies do not provide additional mortality benefits compared with statin monotherapy. The new solutions include fourth-generation statin molecules that primarily aim to enhance the NO-donor capacity of statins, and to reduce their muscle toxicity. Certain compounds that affect cholesterol synthesis (squalene synthase inhibitors, MTP inhibitors, ACAT inhibitors) need to be further analysed because of the risk of side effects. The use of an antisense oligonucleotid that blocks the mRNA of apoB, the main protein on the LDL-particle and antibodies that inhibit the protein PCSK9 that promotes the intracellular breakdown of the LDL-receptor seems to be much more promising. Besides the lowering of LDLcholesterol level, studies have focused on the benefits of increasing HDL-cholesterol levels. Unfortunately, recently completed analyses show that new forms of the strong HDL-C increasing nicotinic acid have not provided any additional benefit when added to statin therapy. Similarly, the adverse effects associated with the promising CETP inhibitors and the lack of additional benefit when combined with statins question the significance of this drug class. The necessity for an absolute increase of HDL-cholesterol levels needs to be revised on the basis of new data, in other words, the exact role of the HDL particle in atherosclerosis needs to be further investigated.]

[The atherosclerosis can not only be prevented, but also can be cured ]

MÁRK László

[The process of atherosclerosis nowadays plays an important role in the health care not just as a major cause of the most common cardiovascular diseases which lead to death, but also as a major factor in the loss of age-related elasticity in the blood vessels. Over the past two decades, large studies have shown that the treatment of high cholesterol levels can reduce the frequency of cardiovascular events and death and have confirmed the ability to reduce the already existing atherosclerotic plaque, which is almost unique in pharmacotherapy. Using lipid lowering therapy, if we do it properly, we can not only prevent vascular events, but can also cure atherosclerosis. Currently there are three drug groups (statins, ezetimibe and PCSK9- inhibitors), which have complete evidence that their use can reduce the number of cardiovascular events and plaque regression can be achieved. Despite many convincing clinical trials, lipid-lowering therapy is on the cardiovascular prevention palette in the just tolerated or forced applied category. In order to take advantage of its potentials at an appropriate level, as doctors, we have to approach to it by considering its importance. We should communicate to our patients that it’s about a life-long treatment, which not only can reduce the possibility of cardiovascular events, but also can slow down the aging process of the arteries. ]

[“BONE” IN THE VESSELS, “FAT” IN THE BONES? - THE THEORY AND CLINICAL SIGNIFICANCE OF VASCULAR CALCIFICATION]

SPEER Gábor, LAKATOS Péter

[Pathologist have recognized arterial calcification for over a century described also by Virchow in the 19th century. Vascular calcification, an active mechanism, involves a complex, regulated process of biomineralization resembling osteogenesis. Evidence indicates that proteins controlling bone mineralization are also involved in the regulation of vascular calcification. The atherosclerotic plaque calcification can be easily detected noninvasively with radiological methods currently available and it correlates with the amount of atherosclerotic plaque. Also, it serves as a surrogate measure for atherosclerosis, allowing preclinical detection of the disease. There are several examples for the relationship between hyperlipidaemia and increased loss of bone mass. It is not surprising that the base drugs for osteoporosis also have the characteristics for lowering vascular calcification and are antiatherogenous and antilipaemic drugs. The clinical importance ot these facts is that vascular calcification is associated with higher risk of cardiovascular events. In the summary, the authors review the four histopathological types of arterial calcification and the molecules and proteins involved in these processes.]

[Immune responses and neuroimmune modulation in the pathogenesis of acute ischemic stroke and poststroke infections]

PAPP Viktória, MOLNÁR Tihamér, BÁNÁTI Miklós, ILLÉS Zsolt

[Acute-onset cerebrovascular diseases are connected to a number of immunological changes. Here, we summarize immune responses participating in the evolution of atherosclerotic plaques and poststroke local immune responses in the injured CNS as well as in the systemic circulation. Ischemic injury of the CNS alters the balanced neuroimmune modulation resulting in CIDS, the central nervous system injury-induced immune deficiency syndrome. Due to the immunodepression and reduced pro-inflammatory immune responses, the susceptibility for infection is increased; indeed, poststroke infection plays a major role in stroke-related mortality. On the other hand, CIDS may protect against damaging autoimmune responses elicited by exposed CNS antigens. Investigation of immune responses related to ischemic stroke may result in novel therapies indicated by an increasing number of experimental and clinical trials altering poststroke immune responses and preventing infections.]
