[Prompt recognition and evaluation of hypertensive urgencies and emergencies can substantially decrease definitive target organ damage and mortality. Most frequent cause of sudden increase in blood pressure is stopping antihypertensive treatment. In hypertensive crises quickly acting parenteral drugs are of choice, while in urgencies orally administered ones might be sufficient. Cerebral and coronary hypoperfusion should be avoided therefore blood pressure must be decreased gradually.]

[Incorporation of ortho- and meta-tyrosine into cellular proteins leads to erythropoietin-resistance]

MIKOLÁS Esztella Zsóka, KUN Szilárd, LACZY Boglárka, MOLNÁR Gergő Attila, SÉLLEY Eszter, KŐSZEGI Tamás, WITTMANN István

[Introduction: Erythropoietin (EPO) is a glycoprotein hormone, which is responsible for the proliferation and differentiation of erythroid cell lines. Since it is widely used as the treatment of renal anaemia, EPO-resistance is a common concern. Aims: We aimed to perform in vitro experiments to investigate a possible mechanism of EPO-hyporesponsiveness. Methods: We used a factor dependent erythroblast cell line (TF-1). Two independent observers calculated cell counts simultaneously on day 1; 2 and 3 in Bürker cell counting chambers. Colorimetric method was used to measure protein concentrations. Measurement of protein-bound para-, ortho- and meta-tyrosine was performed with reverse phase high performance liquid chromatography with fluorescence detection. We determined ERK and STAT5 activation using Western blot method. Results: In case of ortho- and meta-tyrosine pretreated cells time-dependent, EPOinduced proliferative activity was decreased compared to the 1.7 fold elevation of cell counts seen in para-tyrosine cultured cells. Protein concentration of ortho- and metatyrosine treated samples was significantly lower than control cells on the third day. Addition of para-tyrosine reclaimed EPO-sensitivity. Erythroblasts treated with orthoor meta-tyrosine contained lower concentrations of protein-bound para-tyrosine with higher ortho- and meta-tyrosine content. EPO dependent activation of ERK and STAT5 could be inhibited by ortho- or meta-tyrosine treatment. Conclusions: Elevated level of protein-bound ortho- and meta-tyrosine in erythroblasts can result in the pathological modification of intracellular signaling, leading to EPOhyporesponsiveness.]

[Prevalence and care of prediabetic patients in the Hungarian hypertensive population]

KÉKES Ede, KISS István

[Authors studies the incidence of hypertensive patients with prediabetes - according to the IFG criteria - based on the 2005 Hungarian Hypertension registry (38849 subject) and on the „Live under 140/90” sub-program („Prevent it”) (23670 subject) database. The presences of diabetes patients were excluded. IFG incidence (from 5,6 to 7,1 mmol/l) was found between 13-18% of the adult population over 40 years. In men, the incidence was significantly higher. In individuals with IFG the BMI, waist circumference values were significantly higher than the average normal values and exceeded the danger zone. For women significantly higher values were found. These patients had higher total cholesterol and blood pressure values. After three months of intensive supervision, counseling, care over every 40 years age group - without medication - significantly decrease the fasting blood glucose values. They presented the international experiences of prediabetes.]

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


[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]


[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.]

[Sudden death – ECG – hypertension]


[Sudden death (HH) is not only associated with coronary heart disease or heart failure, but is also present in hypertension, primarily associated with left ventricular hypertrophy, systolic pressure, and age. Co-morbidities of hypertension (diabetes, coronary heart disease, heart failure and renal failure) contribute greatly to its development. HH occurs due to ventricular fibrillation, or asystole. The auther demonstrates depolarization and repolarization pathologies leading to HH and detectable on the ECG and their characteristic ECG patterns. He also emphasizes the importance of resting heart rate and heart rate variability.]

[Prevalence and treatment of hypertension in patients with newly diagnosed familial hypercholesterolemia]

NÁDRÓ Bíborka, DIÓSZEGI Ágnes, KOVÁCS Beáta, PARAGH György, PÁLL Dénes, HARANGI Mariann

[Familial hypercholesterolemia (FH) is an inherited defect of cholesterol metabolism characterized by high plasma total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels and premature cardiovascular disease risk. Prevalence of hypertension in FH is not clarified, but its appearance is independent risk factor for the development of cardiovascular disease. Therefore, optimal treatment has a major priority in this high-risk population. We aimed to investigate the lipid parameters and evaluate the presence of hypertension and its treatment characteristics in 86 newly diagnosed, untreated heterozygous FH patients (27 males, 59 females, mean age 53.6±13.4 years). We diagnosed FH by using the Dutch Lipid Clinic Network criteria. The mean TC level was 8.49±1.7 mmol/l, the mean LDL-C level was 6.11±1.5 mmol/l, the mean high-density lipoprotein cholesterol (HDL-C) level was 1.62±0.5 mmol/l, while the median lipoprotein (a) level was 301 mg/l. We diagnosed 33 FH patients (38.4%) with hypertension. Beta blockers were used in 23, ACE-inhibitors in 13, ARBs in 12, calcium channel blockers in 9, and HCT in 11 cases. 11 patients was treated with monotherapy, for 10 patients double, for 11 patients triple, while for 1 patient quadruple combined antihypertensive therapy was administered. Based on our results, hypertension might be underdiagnosed in this specific patient population. Neither the types nor the combination patterns of blood pressure lowering agents are in line with current guidelines. Up to date screening and treatment of hypertension should be worth considering in this extremely high risk population with enhanced atherosclerosis.]

[Monitoring of effectiveness of ramipril-amlodipine fixed combination, a non-interventional trial (Ramona study). Subgroup analysis of patients with chronic kidney disease]


[Hypertension and chronic kidney disease are independent cardiovascular risk factors. The 5th Cardiovascular Consensus Conference has recommended chronic kidney disease in high-risk category. In chronic kidney disease hypertension is observed in most cases. In patients with chronic kidney disease blood pressure targets are as 140/90 mmHg blood pressure below must be achieved without overt proteinuria. In chronic kidney disease combined antihypertensive therapy treatment should be initiated according the Hungarian Society of Hypertension recommendations. Aims: Monitoring the effectiveness and safety of the fix combination of ramipril/amlodipine Egiramlon® therapy in chronic kidney disease suffering from mild or moderate hypertension despite antihypertensive treatment. Patients and methods: Open, prospective, phase IV clinical observational study, which involved known chronic kidney disease (age over 18 years) with mild or moderate hypertension. Ramipril/amlodipine fixed combination (5/5, 5/10, 10/5 or, 10/10 mg) were administered or titrated in three visits, during the 4 months of trial period. The doses of the fixed combination drugs were determined individually during the visits by the 923 physicians involved in the study. The target blood pressure value was <140/90 mmHg according the new guidelines of ESH/ESC. Results: 70.1% of total patient (9169) was fulfilled the protocol during the four month of trial (6423 patients). In this population 194 patients suffered from chronic kidney disease. The age of patients was 68.52±1.84 (mean±SD) years, 85 (43.8) women and 109 (56.2%) men. 74.74% of total patients with chronic kidney disease has reached target blood pressure at the end of 4th month (primary endpoint). The blood pressure has decreased significantly (all p<0.0001) from 158.04/90.46±9.97/8.30 mmHg (1. visit) to 138.77/82.12±10.68/7.21 mmHg 2. visit and to 130.40/78.59±7.56/5.75 at the and of trial (3. visit), it means -27.64/- 11.87 mmHg decrease from the beginning of the 4th Month (3. visit). eGFR level increased significantly from 46.3±16.49 ml/min/1,73m2 to 49.0±19.58 ml/min/1,73m2. Patients suffered from chronic kidney disease have tolerated well the various doses of fixed combination of ramipril/amlodipine, and adverse events have no occurred correlation of treatment.]
