[The renin-angiotensin system (RAS) is one of the most important mechanisms regarding the pathomechanism and treatment of hyprtension. The most of the elements of the RAS are found in the nervous system too. The effect of angiotensin converting enzyme inhibitors and angiotensin receptor blockers (ARBs) is based on the inhibition of the RAS. ARBs might have a special role in the central nervous system because they do not decrease the production of angiotensin but inhibit its harmful effects mediated through the AT1 receptor while allowing the stimulation of AT2 receptors with resulting pleiotrophic actions. Hypertension is the most important risk factor for stroke and has a negative effect on cognitive functions. Antihypertensive treatment has an effect on the nervous system; in addition to the consequences of the reduced blood pressure, ARBs might provide additional advantages in stroke and dementia prevention.]

[Mirror neurons and interpersonality in the paradigm of embodied mind]

HORVÁTH Lajos, SZABÓ Attila

[In this paper, our aim is to scrutinise the psychology and phenomenology of interpersonal relationships from an interdisciplinary viewpoint. This multi-perspectival examination has a key concept: we critically discuss the interdisciplinary dialogues and philosophical appraisals regarding the issue of mirror neurons. Empathy and resonance phenomena have philosophical, psychological, and biomedical importance. Our paper, by applying certain philosophical and empirical results of the overarching paradigm of embodiment, attempts to shed light on several semantic problems, which could come up with respect to the function of mirror-neurons. In conclusion, we would like to attempt to utilise the results of contemporary phenomenology in order to clear some semantic problems, considering the features of mirroring and resonant behaviour.]

[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.]

[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.]

Cholinesterase inhibitors and memantine for the treatment of Alzheimer and non-Alzheimer dementias

BALÁZS Nóra , BERECZKI Dániel, KOVÁCS Tibor

In aging societies, the morbidity and mortality of dementia is increasing at a significant rate, thereby imposing burden on healthcare, economy and the society as well. Patients’ and caregivers’ quality of life and life expectancy are greatly determined by the early diagnosis and the initiation of available symptomatic treatments. Cholinesterase inhibitors and memantine have been the cornerstones of Alzheimer’s therapy for approximately two decades and over the years, more and more experience has been gained on their use in non-Alzheimer’s dementias too. The aim of our work was to provide a comprehensive summary about the use of cholinesterase inhibitors and memantine for the treatment of Alzheimer’s and non-Alzheimers’s dementias.

[Monitoring of the blood pressure lowering effectiveness of ramipril-amlodipine fix combination – a non-interventional trial (RAMONA study)]

TOMCSÁNYI János

[Purpose: Monitoring the effectiveness and safety of the fix combination formulation Egiramlon® therapy containing ramipril and amlodipin in patients, suffering from mild or moderate hypertension despite antihypertensive treatment. Patients and methods: Open, prospective, phase IV clinical observational study, which involved 9169 patients (age >18) with mild or moderate hypertension [TUKEB No: 16927- 1/2012/EKU (294/PI/12.)]. Ramipril/Amlodipin 5/5, 5/10, 10/5, 10/10 mg combinations were administered/ titrated in three visits, during the four months period according to the physician’s decision Blood pressure was measured by validated blood pressure sphygmomanometry and ABPM (Meditech, Hungary). The dosis of the fix combination formulation was determined individually during the visits by the 923 doctors involved in the study. The target blood pressure value was 140/90 mmHg, but in case of high risk patients population (diagnosed cardiovascular disease, diabetes), 130/90 mmHg target value was determined. Results: In 70.1% of the patients had no protocoll deviation. Patients data and examination results were processed according to this 6423 patient population. The average age of the patients were 60.2 year, in 50-50% sex distribution. The average duration of the treated hypertension was 9.8 years and the average blood pressure value was 157/91 mmHg. Till the end of the study, systolic blood pressure has decreased with 26.4 mmHg and diastolic pressure with 11.8 mmHg. An average 5.5 bpm heart rate frequency decreasing was observed at the end of the study. As a result of the treatment 52.4% of the patient population has reached the target blood pressure value.]

[Hypertension, COPD and COVID-19. Focus on antihypertensive therapy]

FARSANG Csaba

[Chronic obstructive pulmonary disease is a very common comorbidity of hypertension and it is often unrecognised by physicians. The factors involved in the pathomechanism of both diseases should be realised when choosing treatment. Among factors, hypoxia, increased tone of sympathetic nervous system and activation of renin-angiotensin-aldosterone system should primarily be considered. Vascular wall damage and endothelial dysfunction has an important role in both conditions. The goals of treatment are elimination of risk factors, optimizing the blood pressure, the consequential prevention of cardio-cerebrovascular, renal and pulmonary damage; finally prolonging the patients’ life and improving their quality of life as well. Both hypertension and COPD significantly worsen the condition of COVID-19 patients since they increase the severity of the disease and the rate of in-patients’ and their mortality. In the treatment of hypertension among COPD and COVID-19 patients there must be emphasized the medication inhibiting of renin-angiotensin-aldosterone system, such as angiotensin-converting en­zyme inhibitors or angiotensin-II AT1 re­cep­tor antagonists. Special attention concerned the beneficial effect of mineralocorticoid receptor antagonist spironolactone. Other antihypertensive drugs (calcium channel blockers, thiazide-like diu­retics, high selectivity β1 receptor antagonists) may supplement the treatment if necessary. Long-acting β2 receptor agonists, muscarinic receptor antagonists and inhalation corticosteroids may be administered in double or triple combination also in hypertension and COPD as well. It is important to note, that statin therapy and also vitamin D3 improve the condition of COVID-19 patients.]
