[Endothel dysfunction and hypertension]

KELEMEN Judit, BLASKÓ György

[In the past two decade numerous data has been collected about the role of endothelium in the development of several cardiovascular disorders i.e. hypertension, congestive heart failure and atherosclerosis. Endothelial cells had been thought to be passive barriers only, but it turned out that through paracrine and autocrine hormone secretion they take part in modulating and regulating the vasodilator and vasoconstrictor effects being directed to vascular smooth muscle cells. The intact endothelium prevents the adhesion of platelets and monocytes, the platelet aggregation, as well as the migration and proliferation of vascular smooth muscle cells. It has been shown that both in experimental and human hypertension the endothelial function i.e. the so-called endothel-dependent vasodilatation is damaged, being the main feature of endothelial dysfunction. In spite of extensive research it is not clear whether endothelial dysfunction is a cause or a consequence of hypertension, with exact pathomechanism being also unclear. Methods, by which this important parameter could be precisely measured are under development. Researchers also examine whether recently used antihypertensive agents could improve or eliminate endothelial dysfunction and whether this effect may offer benefit to patients in terms of morbidity and mortality. This article attempts to summarize the most up-to-date information about the endothelial dysfunction research.]

[Sentinel node biopsy in melanoma malignum]

OLÁH Judit, GYULAI Rolland, VARGA János, MOHOS Gábor, KAPITÁNY Klára, PAPOS Miklós, PÁVICS László, VARGA Erika, KOROM Irma, DOBOZY Attila

[INTRODUCTION - For many decades there has been no adequate treatment for affected regional lymph nodes in melanoma malignum. In the last couple of years with the implementation of the sentinel lymph node biopsy technique, it became possible to perform selective lymphadenectomy, i.e. to perform radical block dissection only in cases of histologically proven metastases in the sentinel lymph nodes. Since the lymphatic involvement in melanoma malignum is the most important prognostic factor, it is essential to treat lymphatic etastases as early as possible to get the best results. PATIENTS AND METHODS - In the past two years we have removed the sentinel lymph nodes together with primary tumors being 1 mm or thicker, ulcerated and regressive, based on clinical appearance in 120 melanoma cases. RESULTS - Of the 120 sentinel lymph node biopsies 58 contained metastatic cells. Beside tumor thickness, histological features of regression were found to correlate with the positivity of the sentinel nodes in thin melanoma cases. CONCLUSIONS - Sentinel lymph node biopsy is a relatively simple procedure with minimal complication rate. It allows early therapeutical block dissection and the selection of patients who require adjuvant therapy. Our clinical observations suggest that beside tumor thickness and ulceration, the clinical and histological signs of regression are important factors to consider for the indication of sentinel node biopsy.]

[Wegener’s granulomatosis: diagnostic questions]

CSISZÉR Eszter, SOLTÉSZ Ibolya, FÜZESI Katalin

[INTRODUCTION - Wegener’s granulomatosis is a disease of unknown origin classified as an immune vasculitis. The main pathologic feature is necrotising granulomatous small vessel vasculitis. Clinically the upper and/or lower airways are affected most often as well as the kidneys in the generalised form. The highly specific antineutrophil cytoplasmic antibodies have diagnostic significance beside the pathology and clinical symptoms. PATIENTS AND METHODS - We have studied the clinical and diagnostic characteristics of 15 cases diagnosed in our centre from the last 25 years. All patients had pulmonary manifestation. We analysed the organ involvement, clinical signs indicating the diagnosis, chest radiography, chances for biopsies of diagnostic significance and the difficulties of differential diagnostics. RESULTS - The diagnosis was made based on histological samples from the upper airways in three cases and from the lower airways in six cases (in four cases the bronchoscopic biopsies were diagnostic, in two patients thoracotomy was necessary). In six cases, clinical signs and typical organ manifestations were the basis of the diagnosis. CONCLUSION - This very rarely occurring disease which is difficult to recognise requires pulmonological examination due to the involvement of lungs. If this diagnosis comes to mind - based on findings of bilateral, multiplex, round pulmonal shadows with cavitation - the pulmonologist should search for other organ manifestations and involve respective specialists. Ideally, diagnosis is established by histopathology or by positive cytoplasmic antineutrophil cytoplasmic antibodies.]

[How can the fixed-dose atorvastatin/amlodipin combination help better adherence of patients to therapy?]

KIRÁLY Csaba, BENCZÚR Béla

[Among the main risk factors of cardiovascular disease which is the leading cause of death dyslipidemia has a great importance beyond hypertension, diabetes, smoking and obesity. These conditions rarely occure as isolated ones but very often a clustering of major CV risk factors within individual patients can be observed called metabolic syndrome. It’s a great challenge to convince asymptomatic but high-risk adults that they have to take a lot of medicine for a long time period uninterruptedly to prevent future vascular events (eg. MI or stroke) in the primary care settings. Mainly the low statin-adherence means the greatest problem particularly if a subject should take statin beside two or more drugs despite statins have the most prominent evidences in the field of cardiovascular prevention. The efficacy in improving adherence to therapy of fixed-dose atorvastatin/amlodipin combination was investigated in this paper based on the experiences of case reports derived from our clinical practice.]

[THE ROLE OF SIMVASTATIN IN THE TREATMENT OF DIABETIC DYSLIPIDAEMIA]

BALOGH Zoltán, PARAGH György

[Patients with type 2 diabetes have markedly increased cardiovascular morbidity and mortality. Type 2 diabetes is typically associated with atherogenic dyslipidaemia, which is characterized by elevated triglycerides, low plasma levels of high-density lipoprotein cholesterol, and an increased ratio of small, dense lowdensity lipoprotein particles. Current treatment guidelines stress the importance of lipidlowering therapy in reducing cardiovascular risk in diabetic patients. Statins currently represent the cornerstone of dyslipidaemia management, based on their ability to efficiently reduce cardiovascular risk through lowering low-density lipoprotein cholesterol. They have, however, a relatively modest effect on the components of atherogenic dyslipidaemia, since they reduce triglycerides by only 15 to 35% and elevate high-density lipoprotein cholesterol by less than 10%. This raises the need for combining statins with other lipid-lowering drugs (ezetimibe, nicotinic acid, fibrate) at an early stage of type 2 diabetes. Authors review the role of simvastatin monotherapy in the treatment of diabetic dyslipidaemia and summarize the results of studies on simvastatin as part of a combined lipid-lowering treatment.]

[Clinical impact of acetylsalicylic acid resistance in patients with cerebrovascular disease]

FEHÉR Andrea, PUSCH Gabriella, HARANG Gábor, GASZTONYI Beáta, PAPP Előd, WERLING Dóra, MENYHÁRT Marianna, KOMÁROMY Hedvig, SZAPÁRY László, FEHÉR Gergely

[INTRODUCTION - In the past few years, a number of studies have been published about acetylsalicylic acid resistance and its potential clinical consequences. PATIENTS AND METHODS - 281 patients with chronic cerebrovascular disease have been involved in our study. The patients were divided in two groups on the basis of their optical aggregometer results (acetylsalicylic acid responder vs. resistant). We compared the risk profiles, drug therapies, laboratory parameters and clinical outcomes of the two groups. RESULTS - Acetylsalicylic acid resistant patients were more likely to be women [23 (45.1%) vs. 92 (40%) (p<0.05)], to smoke (38% vs. 25%), have hypertension (92 vs. 78%), hypercholesterolaemia (5.69 vs. 4.85 mmol/l), and elevated LDL-levels (3.71 vs. 2.85 mmol/l), triglyceride levels (2.78 vs. 1.97 mmol/l) and hsCRP levels (17.89 vs. 7.09 mmol/l) (p<0.01). The use of statins was more frequent (56% vs. 36%) in the responder group (p<0.01). Platelet aggregation values (triggered by agonists) were significantly correlated with cholesterol, LDL, triglyceride and hsCRP levels (p<0.05). Adverse outcomes were reached in 13 (25.5%) acetylsalicylic acid nonresponders and 32 (13.9%) acetylsalicylic acid responder patients (p<0.01). In a multivariate analysis, however, only smoking (OR: 2.38, CI: 1.77-5.44) and increased LDL (OR: 3.01, CI: 2.34-5.67) and hsCRP levels (OR: 2.44, CI: 1.55-7.02) (p<0.05) were independent risk factors of adverse vascular outcomes. CONCLUSION - On the basis of our results, acetylsalicylic acid resistance was associated with a worse clinical outcome, but it was not an independent risk factor of future ischaemic events. Our results implicate that inappropriate prevention therapy might have a role in this phenomenon.]

[Defending the statins]

MÁRK László

[Taking into account the frequent occurrence of coronary heart disease and the mortality related to this, it is obvious that the primary and secondary prevention of cardiovascular events is nowadays a major challenge in medicine. The lipid lowering therapy has become the basic element of the prevention and the statins are first-choice drugs in this field. Despite the great amount of the evidences coming from studies based on the principles of the evidence based medicine, the statins are frequently in the crossfire of undeserved offensives. The unexplainable reluctance to statins is frequent not only among the misled patients but among doctors too. The attitude of the latter to the treatment determines the patients’ compliance. The change of this attitude is the aim of this paper. This potential change and the continuous education of the patients are the most common possibilities for the improvement of the bad statin persistence and adherence. ]

[IMPORTANT AIM OF STATIN THERAPY: ISCHEMIC CARDIOVASCULAR EVENT (STROKE)]

CSÁSZÁR Albert

[Statin’s treatment clearly is authorized in prevention of coronary heart disease (CHD). According to the results of many studies and meta-analyses statins can inhibit the first cerebrovascular infarct (stroke). The greater the decrease of LDL-cholesterol level the more prominent the efficacy. The effect is not so robustic compared to coronaria vessels moreover clear pleiotropic (cholesterol independent) action takes also part. It has been nowadays revealed that high dose (80 mg) atorvastatin can confine first time the development of recurrence stroke (SPARCL study), which is an important fact in the field of secondary prevention.]
