Lege Artis Medicinae - 2006;16(12)

[Beta-receptor blocking agents are considered a well defined class of drugs for treating hypertension and heart failure. Nebivolol, a thirdgeneration beta-blocker that combines marked beta-1-receptor selectivity with a vasodilator and antioxidant effect, has relatively recently become available in Hungary. The vasodilator effect of nebivolol has proved to be mediated by the endothelial NO pathway. Due to its neutral metabolic effect, nebivolol can safely be used in patients with glucose intolerance or lipid disorder. Nebivolol is a safe and well tolerated antihypertensive agent. Based on the results of recent clinical trials, nebivolol is also indicated for the treatment of heart failure.]

[CLINICAL ASPECTS OF NOCTURNAL GASTRO-OESOPHAGEAL REFLUX]

DEMETER Pál

[Gastro-oesophageal reflux that occur at night has special clinical features and thus require extra attention. During sleep most anti-reflux mechanisms diminish, which results in prolonged contact between gastric acid and oesophageal mucosa compared to reflux during the day. Nighttime reflux symptoms adversely affect quality of life, vitality, physical and mental health. A further important consequence is the potential exacerbation of respiratory disorders such as asthma and sleep apnea. There is increasing interest in the association between nocturnal reflux and certain extra-oesophageal symptoms, including reflux laryngitis and chronic cough. An increased risk of erosive damage and adenocarcinoma of the oesophagus are also observed among patients who report nocturnal reflux symptoms. The primary goal of treatment is to improve quality of life and reduce the risk of complications by decreasing the time of acid contact with oesophageal mucosa. Nighttime reflux symptoms are much more difficult to control than daytime symptoms. Treatment guidelines generally recommend lifestyle changes as the initial approach in managing nocturnal symptoms, however, this is successful in only a small proportion of patients. Evidence-based reviews and meta-analyses favour the use of proton pump inhibitors in the treatment of gastro-oesophageal reflux disease and reflux-oesophagitis. Proton pump inhibitors are the most efficient acid-suppressing agents and thus diminish the harmful effect of acidic gastric reflux on the oesophageal mucosa. In addition, by decreasing the volume of gastric acid, they reduce the tendency to reflux.]

[SEVERE THERAPY RESISTANT BRONCHIAL ASTHMA]

HERJAVECZ Irén, BÁNKÚTI Beáta, CSOMA Zsuzsanna

[While severe asthma associated with high morbidity affects a relatively small proportion of all patients with asthma, it requires special attention and innovative treatment approaches. Although asthma is by definition characterized by reversible airflow obstruction, the obstruction becomes fixed to some extent and refractory to corticosteroids with the progression of the disease. The underlying change in this phenotype is airway wall remodelling. In allergic asthmatic patients who remain symptomatic despite highdose inhaled corticosteroid therapy, blockade of IgE with omalizumab confers appreciable clinical benefit. Chronic severe asthma is also accompanied by a marked increase in TNFproduction that might contribute to corticosteroid resistance. In accordance with this, TNF blockade with entanercept has been shown to improve asthma controll and at the same time to reduce bronchial hyperresponsiveness. Identification of new susceptibility genes, such as ADAM33, will provide further targets for therapy, which in turn can result in the development of treatment tools that modify the natural course of asthma and reverse the changes associated with airway remodelling, rather than simply suppress inflammation and dilate the airways.]

[DISCREPANCIES BETWEEN THE CLINICAL AND PATHOLOGICAL DIAGNOSES IN CASES OF MALIGNANT TUMOUR]

KOVÁCS Attila, ILLYÉS György, SCHÖNFELD Tibor, SCHAFF Zsuzsa

[INTRODUCTION - In Hungary, like in other countries, previously undiagnosed diseases are frequently discovered at autopsies despite the availability of modern diagnostic tools. The aim of this study was to determine the accuracy of clinical diagnosis in malignant tumour cases. METHODS - Between 1996 and 2006, 5005 autopsies were performed in our institute. Malignant tumour cases with differing clinical and pathological diagnoses were selected and revised with regard to the localization of the primary tumour and the type of diagnostic difference, i.e., false negative, false positive or difference in the tumour site. The proportion of tumours with clinically undetermined primary site that were subsequently recognized at autopsy was established. The causes of misdiagnoses and the appropriateness of therapy were also analysed with regard to whether diagnostic mistakes were made and whether these significantly affected disease outcome. RESULTS - Of 1495 autopsies 235 cases (16%) showed a difference between the clinical and the pathological tumour diagnosis and a further 74 cases (5%) had a clinically undetermined primary tumour. Of the misdiagnosed cases 57% were false negative, 23% were false positive and 20% differed in their localization. Autopsy clarified 75% of the clinically undetermined primary tumours. Overall, there was one misdiagnosis or undetermined primary localization for every 5 correct clinical diagnoses (309/1495, 21%). The most frequent misdiagnosed tumours were lung, liver and kidney cancers. Most (60%) misdiagnoses were due to factors independent from the clinician, so these in fact were not diagnostic errors. Out of the remaining 40%, the true diagnostic error had an adverse effect on disease outcome in 11%.. CONCLUSION - Despite of the use of modern diagnostic tools the rate of clinically misdiagnosed malignant tumours is high, therefore, autopsy will still play an outstanding role in the future in quality control of clinical activity and education.]

[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.]

[Experience with coenzyme Q10 in heart failure]

KOHUT László

[INTRODUCTION - The protein complex coenzyme Q10 (CoQ10) has a role in ATP production as a mitochondrial electron transport molecule, and it also has a strong antioxidant effect. Several studies have proved the correlation between the decrease in CoQ10 level and the severity of heart failure. Heart failure is a multifactorial syndrome, the development of which is greatly influenced by an abnormal energy metabolism. CASE REPORT - The 61-year-old woman developed heart failure after a myocardial infarction. She complained of fatigue, dyspnoea and reduced physical endurance even with optimal treatment. When her therapy was completed by CoQ10, her endurance and life quality significantly improved and her symptoms ameliorated. CONCLUSIONS - Medical treatment of chronic heart failure is an evidence-based, complex therapy. Despite the complex management, morbidity and mortality of this condition remain high. A number of studies have shown that CoQ10 substitution can improve the clinical and haemodynamical parameters of patients with heart failure. On the basis of these results, the use of CoQ10 as an adjuvant therapy to complex treatment has an increasing role.]

[Epidemiology of hypertension in Hungary]

SZEGEDI János, KÉKES Ede, SONKODI Sándor, KISS István

[The most important aspects of Hungarian hypertension epidemiology are demonstrated. The prevalence of hypertension is continuously increasing and in 2011 from the nearly 10 million population exceeded 3 million. Its occurrence rises in parallel with the increase in of systolic blood pressure and the progression of age, and exceeds 60% in those aged over 65 years. The average blood pressure is increasing in children and adolescents, and isolated systolic hypertension is often observed in those over 65-70 years. The situation is closely related to overweight in the young, while in elderly the atherosclerotic process results in low diastolic blood pressure. The prevalence is significantly different in some regions with the highest incidence in South-Transdanubia and North- Hungary. Overall, there is a higher incidence in women. Among known hypertensive patients, the ratio of men is greater till 40-45 years; thereafter, there will be an equilibration and in elderly women the incidence will be higher. It is interesting, that the morbidity and mortality have significantly increased in hypertension and diabetes since 2004, while the incidence of myocardial infarction and stroke has significantly decreased. As concerns organ damage, an increase in occurrence of left ventricular hypertrophy and microalbuminuria has been observed. Metabolic syndrome, diabetes mellitus and ischemic heart disease were the most frequent comorbidities.]

[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.]

[Hungarian data about the ramipril based free or fixed doses combination therapy in connection with patients adherence]

SIMONYI Gábor

[In the treatment of chronic diseases an appropriate therapeutic effect is only achieved with a long-term medication. Hypertension is no exception, because to achieve target blood pressure is of outstanding importance for the prevention of cardiovascular complications. The use of fixed drug combinations according to national and international data increases the patients adherence by 20 percent. In our article we present the one year patients adherence treated with ramipril and amlodipine free combination, ramipril/amlodipine fixed combination and ramipril/hydrochlorothiazide fixed combination in hypertension.]
