[ANTIHYPERTENSIVE THERAPY IN VIEW OF RECENT CLINICAL STUDIES]

ALFÖLDI Sándor

[Different antihypertensive agents, while having the same blood pressure lowering effect, will have significantly and clinically important different impact on the serum levels of glucose, lipids, insulin, potassium, creatinine, as well as on albumin excretion, heart rate, body weight, central pressure, various hypertensive target organ damages, and, in particular, 24-hour blood pressure dinamics. There is agreement in that the main benefits of first-line antihypertensive agents are related to the lowering of blood pressure itself. Some other drugs, however, have shown preventive and protective cardiovascular properties in certain patient groups, independent of their blood pressure lowering effect as measured traditionally.]

[BENEFICIAL EFFECT OF INSULIN DETEMIR ON THE BODY WEIGHT OF DIABETICS]

BECHER Péter

[Detemir is the newest base insulin analogue. In phase III trials and the PREDICTIVE study, the use of insulin detemir in various treatment regimens (basal-bolus or in combination with an oral antidiabetic) did not lead to weight gain in either types of diabetes, in contrast to what is usually observed with insulin therapy. Similar results were obtained when neutral protamine Hagedorn insulin or glargine were replaced by detemir, or insulin-naive patients received detemir as a new therapeutic regime. The mechanism of the beneficial effect on body weight is not clear yet. It may be related to the reduction in the number of hypoglycaemic episodes. It may also be associated with a stronger action of detemir on hepatocytes compared to peripheral tissues due to its acylation, which results in an effective suppression of hepatic glucose output without promoting lipogenesis in the adipocytes. Detemir reaches the insulin receptors of the hypothalamus faster than regular insulin, therefore, satiety develops in a shorter time. These hypotheses still require further studies.]

[INFLAMMATORY BOWEL DISEASE IN CHILDREN]

BODÁNSZKY Hedvig, VERES Gábor

[The term inflammatory bowel disease includes two similar, but distinct intestinal diseases so far of unknown ethiology - ulcerative colitis and Crohn’s disease. They used to be considered diseases of young adults, but in recent decades they have become more common among children, with characteristics different from those in adults. In the past they were considered severe, incurable diseases, but today, owing to modern nutrition, medical and surgical treatment, both diseases have became well manageable, even though complete recovery can not yet be expected.]

[The real cost of caring for seriously ill patients - compassion fatigue or satisfaction]

KEGYE Adrienne, ZANA Ágnes, RÉVAY Edit, HEGEDÛS Katalin

[The improvement of the Hungarian hospice network and the increasing number of people dealing with the seriously ill are reflected by the annual hospice reports (2001-2013). However these reports also draw the attention to the cumulating mental and spiritual burdens of carers which can lead to fatigue and burnout. On the base of practical experience we surveyed the mental and spiritual condition of the caregivers of seriously ill patients and also reviewed research findings and the professional literature on the exposure to imperilment. The grounds of professional literature’s research were the Hungarian and international databases. We favoured studies published in Hungarian or English between 2000 and 2014 primarily on carers working in palliative and hospice service. One of the main profits of reviewing the professional literature is getting more detailed information on the mental state of professional caregivers. Relatively new element in researches is studying the relation between burnout and compassion satisfaction and compassion fatigue. It includes studying of symptoms and coping strategies. These all enable a better understanding of causes and help us to support hospice carers with more effective methods to protect them from mental and spiritual exhaustion.]

[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.]

[REFRACTIVE SURGERY IN THE XXIST CENTURY - SURGICAL CORRECTION OF REFRACTIVE ERRORS]

NAGY Zoltán Zsolt, SZABÓ Viktória, SÜVEGES Ildikó

[Refractive surgical procedures have become more and more popular worldwide. The ultimate aim of these procedures is to change the refractive power of the cornea in order to achieve good uncorrected visual acuity and to get rid of the optical correction need. In this article, the history of refractive surgery, the most important characteristcs and types of the excimer lasers, the most up-to-date refractive surgical techniques and alternative refractive procedures are presented. The lower and upper limits of surgical correction, the newest diagnostic and technical development, i.e. the possibilities of wavefront technology are also discussed.]

[Changes in endothelial cells caused by cigarette smoke]

WAGNER László, LACZY Boglárka, CSEH Judit, TAMASKÓ Mónika, MAZÁK István, MARKÓ Lajos, MOLNÁR Gergő Attila, WAGNER Zoltán, MOHÁS Márton, FEKETE Andrea, WITTMANN István

[Endothelial nitric oxide synthase enzyme is regulated through the phosphorylation of the Ser(1177) and the Thr(495) sites, which influence the biological availabilaty of nitric oxide. We examined the acute effect of cigarette smoke, which decreases nitric oxide production. Endothelial cells were treated with different concentrations and for different times with cigarette smoke buffer, then with reduced glutathione or different protein kinase inhibitors. We determined the total and the phosphorylated nitric oxide synthase levels with Western blot. Cigarette smoke increased phosphorylation in a concentration- and time dependent manner at the Ser(1177) site and more pronounced at the Thr(495) site. Besides, it also led to the dissociation of the active dimer form of the enzyme. Reduced glutathione inhibited these phosphorylations and prevented the dissociation of endothelial nitric oxide synthase enzyme. The inhibition of protein kinase A or B did not influence the effect of cigarette smoke. However, protein kinase C inhibitors increased the phosphorylation caused by cigarette smoke at Ser(1177), but decreased it at Thr(495) sites. Summarized, cigarette smoke shifts the phosphorylation of the enzyme towards an inhibitory state, further on, it leads to the dissociation of the enzymatically active form. This results in the decreased biological availabilaty of nitric oxide, in which protein kinase C may play an important role.]

[MARITAL STRESS, DEPRESSIVE SYMPTOMS AND CARDIOVASCULAR VULNERABILITY IN WOMEN]

BALOG Piroska, MÉSZÁROS Eszter

[INTRODUCTION - Marital stress and depression have proved to be independent biopsychosocial risk factors for cardiovascular disorders. At the same time their interaction increases cardiovascular vulnerability. The Stockholm Female Coronary Risk Study has shown that marital stress was statistically significantly associated with depressive symptoms, in both groups of healthy women and in patients, even after adjusting for age, educational level, menopausal status, body mass index, cigarette smoking, sedentary lifestyle and the severity of heart failure. METHODS - The aim of this study was to investigate the effect of marital stress on depressive symptoms and psychosocial vulnerability in women with coronary heart disease and in healthy women, cohabiting and currently working. Data were obtained from the Hungarostudy 2002, representing the Hungarian population over the age of 18, according to age, sex and county. RESULTS - The results have shown that an increase in marital stress contributes to an increase in psychosocial vulnerability (depression, anxiety, vital exhaustion, sleep complaints) in healthy women and in women with cardiovascular disorders as well. Higher depression has been related with higher marital stress as well. DISCUSSION - The relation between marital stress and depression seems to be independent from socio-cultural, economical differences: the same results have been found in Hungarian and Swedish women. This relation seems to be bidirectional: a bad marriage increases the prevalence rate of depressive symptoms and depression worsens marital quality. At the end we propose a conceptual framework for how marital stress and depression increases cardiovascular vulnerability in women, emphasizing circular causality.]
