[In the past decades an increasing attention has been paid regarding the possible role of the immune system in the development of hypertension. In vitro and in vivo animal experiments, as well as human studies provided evidence for the role of the innate and adaptive immune systems in the development of hypertension, especially in connection with the perivascular adipose tissue, heart and kidney. Inflammatory mediators, cytokines, reactive oxygen metabolites have not only local pro-hypertensive effecting the vasculature, but also influence the development of hypertension through other regulatory mechanisms, such as the central nervous system. These findings provide a new understanding of the development of hypertension, as well as offer new potential mechanisms that can be targeted with novel the - rapies.]

[The importance of the increase in the use of fix dosage combination of calcium channel blockers in the domestic medical practice between 2007 and 2013]

BARNA István, GYURCSÁNYI András

[Antihipertensive therapy in the complex treatment of diabetes mellitus, obesity and lipid metabolism disorder was discussed, which also means the fight against the emergence of cardiometabolic syndrome and chronic renal failure as well. Angiotensin converting enzyme (ACE) inhibitors, angiotensin receptor antagonists (ARBs), calcium channel blockers (CCB), b-blockers and thiazid diuretics with “A” level of evidence reduce cardiovascular morbidity and mortality. The main effect of CCBs is effective antihipertensive vasodilatation, which is the basis of anti-ischaemic, anti-anginal and antihipertensive agents for use in everyday practice. Based on the database of the National Health Insurance, we analyzed changes in the turnover of CCBs between 2007 and 2013 the examined period among CCBs ordered with TB support amlodipin is the most frequently used active ingredient. In December 2007 almost 75% of the prescriptions was amlodipin. That increased to 87,12% by December 2013. CCBs ordered in monotherapy not changed in the examined period, while combinations increased continuously Among CCBs between 2007 and 2013 the fix dosage combinations available with TB support are: statins (atorvastatin + amlodipin), ACE inhibitors (ramipril + felodipin, lisinopril + amlodipin, perindopril + amlodipin, ramipril + amlodipin, verapamil + trandolapril) and b-blockers (metoprolol + felodipin). Using the assigned CCB monotherapy decreased steadily during the study period, while the use of combination formulations induced gradually increased. At the end of the examined seven year period more than 40% of the prescribed boxes were CCB in fix combination. Use of the combination of amlodipin + perindopril increased while amlodipin + lisinopril continuously reduced. The use of the combination of felodipin + ramipril also decreased.]

[The selective imidazoline I agonist rilmenidine in the combined antihypertensive therapy]

KÉKES Ede

[The rilmenidin as a imidazoline agonist drug strongly decreases the central simpathetic activity, renine release and the RAS activity. Because of these advantageous properties the peripheral vascular resistance falls and the blood pressure decreases. It is very useful especially in stress induced hypertension. The antihypertensive effects of ACE inhibitors and calciumantagonists are increased by rilmenidine. This drug decreases the inzuline resistance, it has a positive effect on the carbohydrate and fat metabolism, because it is useful as a complementary therapy in metabolic syndrome and of type II diabetes mellitus.]

Neuroscience highlights: Main cell types underlying memory and spatial navigation

KRABOTH Zoltán, KÁLMÁN Bernadette

Interest in the hippocampal formation and its role in navigation and memory arose in the second part of the 20th century, at least in part due to the curious case of Henry G. Molaison, who underwent brain surgery for intractable epilepsy. The temporal association observed between the removal of his entorhinal cortex along with a significant part of hippocampus and the developing severe memory deficit inspired scientists to focus on these regions. The subsequent discovery of the so-called place cells in the hippocampus launched the description of many other functional cell types and neuronal networks throughout the Papez-circuit that has a key role in memory processes and spatial information coding (speed, head direction, border, grid, object-vector etc). Each of these cell types has its own unique characteristics, and together they form the so-called “Brain GPS”. The aim of this short survey is to highlight for practicing neurologists the types of cells and neuronal networks that represent the anatomical substrates and physiological correlates of pathological entities affecting the limbic system, especially in the temporal lobe. For that purpose, we survey early discoveries along with the most relevant neuroscience observations from the recent literature. By this brief survey, we highlight main cell types in the hippocampal formation, and describe their roles in spatial navigation and memory processes. In recent decades, an array of new and functionally unique neuron types has been recognized in the hippocampal formation, but likely more remain to be discovered. For a better understanding of the heterogeneous presentations of neurological disorders affecting this anatomical region, insights into the constantly evolving neuroscience behind may be helpful. The public health consequences of diseases that affect memory and spatial navigation are high, and grow as the population ages, prompting scientist to focus on further exploring this brain region.

[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.]

TLR4 (Toll-like receptor-4) expression and frontal-cingulate volumes in schizophrenia

LI Hua, KÉRI Szabolcs

Evidence suggests that pathogen-associated pattern recognition receptors (Toll-like receptors, TLRs) are implicated in the pathophysiology of schizophrenia. TLRs are important in both peripheral immune responses and neuronal plasticity. However, the relationship between peripheral TLR expression and regional brain volumes is unknown in schizophrenia. We therefore assessed 30 drug-naïve, first-episode patients with schizophrenia. TLR4+/TLR1+ monocytes were measured using flow-cytometry. High resolution magnetic resonance images (T1 MRI) were obtained and analyzed with FreeSurfer. Results revealed significant negative correlations between the percentage of TLR4+ monocytes, mean fluorescent intensities, and brain volumes in frontal and anterior cingulate regions. The measures of TLR1+ monocytes did not show significant relationships with regional brain volumes. These results raise the possibility that abnormal TLR-activation is associated with decreased brain volumes in schizophrenia.

[Thiazide- or thiazide-like diuretics should be used in the treatment of patients with hypertension? Particularities of the situation in Hungary]

VÁLYI Péter

[Diuretics have remained the cornerstone of the antihypertensive treatment since their widespreading in the 1960s. According to the 2018 ESC/ESH Guidelines for the management of arterial hypertension, in the absence of evidence from direct comparator trials and recognizing that many of the approved single-pill combinations are based on hydrochlorothiazide, this drug and thiazide-like indapamide can be considered suitable antihypertensive agents. In the 2018 Hungarian guidelines indapamide is named as the most efficacious diuretic in the treatment of patients with hypertension. The aim of the publication is redefining thiazide- and thiazide-like diuretic use in the treatment of hypertensive patients, with particular attention to presently available hydrochlorothia­zide and indapamide, and their combination drugs in Hungary.]

[Physical inactivity and activity. Damage and benefit]

KÉKES Ede, APOR Péter

[Authors address the issue of inadequate physical activity worldwide and analyze their relationship with cardiovascular diseases and total mortality. In the inactivity "world map" it can be seen that in economically developed countries it is very common but other ethnic and regional factors also play a role and it is significantly more frequent at women. In our country this phenomenon due to combination of advanced civilization and computerization is also frequent. From 2000 to 2015, the trend of the presence of physical inactivity (FI) in the high income populations is steadily rising. Convincing evidence suggests that FI increases the risk of many common, serious diseases, including ischaemic heart disease, type 2 diabetes, breast cancer and colon carcinoma, and reduces the life expectancy. For these four diaseses, the incidence of FI occurs in about 1/3 of cases and 35% of total mortality. Its health value (PAF) ranges from 10 to 18%. Low (non-regular) exercise increases the risk of hypertension with or without family history. In subjects with moderate and intensive levels of physical activity (FA), there is a significantly lower mortality rate and the rate of occurrence of major cardiovasculars (CV) diseases compared to those with lower grade FA. Behind the positive effect of physical activity there is a multiple and complicated mechanism that manifests itself in the vascular system, in the physiological adaptation of the heart and in other metabolic and cellular effects. ]
