[2013. and 2015, we examined the correlation between the serum uric acid level and blood pressure, target blood pressure, prevalence of ISH and other diseases associated to high blood pressure used trend analysis and linear regression in 22,668 hypertensive men (mean age 60.8 years) and 24,684 hypertensive women (mean age 64.1 years). We have extended the correlation analysis to metabolic factors (BMI, abdominal circumference, lipid profile, blood sugar) and kidney function. Significant correlation was found between SH level and systolic and diastolic blood pressure as well as target blood pressure. There was a significant correlation between SH level and metabolic parameters (abdominal circumference, BMI, total cholesterol, HDL cholesterol, triglyceride, fasting blood sugar) and in hyperuricemia the prevalence of metabolic syndrome was higher. As the level of SH increases, the prevalence of hypertension-related KVB, ISZB and diabetes have increased. The closest correlation between uric acid levels and chronic kidney disease was in women and between the uric acid levels and ischemic heart disease in men. ur analysis supports the international declaration that hyperuricemia is an independent cardiovascular, metabolic and renal risk factor.]

[Hungarian Hypertension Registry. Different methods and effects of increasing physician-patient cooperation on target blood pressure]

SZEGEDI János, KÉKES Ede, KISS István

[The life expectancy, the mortality and the development of complications of hypertensive patients are fundamentally influenced by the treatment, the effectiveness of care and physician-patient cooperation, the achievement of target blood pressure. Based on the database of the Hungarian Hypertonia Registry, we present three examples of the effect of different solutions for physician-patient cooperation on increasing the blood pressure target. During the two years between 2005 and 2007, we used a complex, versatile method of increasing the patient’s adherence in treated hypertensive patients (17,114 males and 21,772 women), with information, education, home-blood pressure diary, and continuous, regular physician- patient communication (sms, green phone line, website). The target blood pressure was significantly increased from 38.8% to 43.9%, and the rate of growth was higher in women. The increase was also significant in the elderly (over 70 years). In the first quarter of 2011, we launched a wide-ranging education and patient support campaign for 28,018 hypertensive patients under the ‘Everywhere Good, Best Home!’ subprogram for promoting of home blood pressure measurement and its use in therapy. 81.3% of the patients had completed the diaries under ther observation period, the full completion of the diaries was 91.3%. At the end of the third month, the target blood pressure of 135/85 mmHg for HBPM increased from baseline 21.2% to 48.8%. Growth was significant (P <0.001). In the year 2015-2016 we started a one-year, multicentric, prospective, observational study, in which 7735 patients aged 18-64 years were included from the database of Hungarian Hypertension Registry. In the non-active group (3313 people), treated hypertensive patients were controlled according to the traditional care program so far, while the active group members (4422) participated in an intensive care program with telemedicine (smart phone application) and other helping opportunities. The control was done at the end of 3, 6, 9, and 12 months after the start. In the active group, blood pressure dier was done by smart phone and every month, in the non-active group, paper logging was done every 3 months. In the active group, the blood pressure dieries were filled with smart phone every month and in nonactive group the paper dieries only every 3 months. Patient adherence was high in both groups (around 70%) and in the active group was greater than in the nonactive group. Target blood pressure (<140/90 mmHg) in the active group increased from 53.8% to 73.4% and in the non-active group from 49.9% to 68.1%. Studies have shown that patient interaction is determined by good communication between the care team and the patient, success of home blood pressure monitoring. The communicative ability of the care team (physician-nurse pharmacist) greatly influences the achievement of the therapeutic target. Modern telecommunications is another useful option.]

[Role of IL-10 family of cytokines in kidney fibrosis]

PAP Domonkos, VERES-SZÉKELY Apor, SZEBENI Beáta, SZIKSZ Erna, KISS József Zoltán, TAKÁCS István Márton, REUSZ György, SZABÓ J. Attila, VANNAY Ádám

[Chronic renal failure is a major health problem, affecting 8 to 16% of the population. Regardless of the etiology the common hallmark of chronic renal failure is inflammation, leading to the activation of renal myofibroblasts. Chronic activation of myofibroblasts lead to abnormal accumulation of extracellular matrix, disruption of the architecture of the kidney and finally to reduced renal function. Although our knowledge is rapidly expanding about the pathomechanism of chronic renal failure, we still have no drug to treat or hinder the progression of the disease. In our present review article, we summarize the role of the cytokines of the IL-10 family in renal scarring.]

[The prevalence of therapy resistant hypertension]

FEJES Imola, ÁBRAHÁM György, LÉGRÁDY Péter

[In our country as well as around the world the most common chronic disease is the hypertension, and it is also an important risk factor causing disability and premature death. Within this, getting to know the true prevalence of therapy- resistant hypertension is important also from a public health perspective, since the prognosis of it is worse than that of those who reaches goal blood pressure range. It usually comes with hypertension mediated organ damages and higher (2- 2.5 folder) cardiovascular risk. It is prevalence in the literature is from 5% to 30%. The knowledge of the true prevalence depends on many factors, like: there are many different definitions of resistant hypertension, what is the main profile of the data collecting study site and what level of the health care system it works, or for example a questionnaire of a multicenter trial cannot be used totally in each country and study site.]

[Hypertension and pregnancy]

JÁRAI Zoltán, VÁRBÍRÓ Szabolcs

[Hypertension complicates approximately 10% of the pregnancies and with this high blood pressure is the most frequent cardiovascular comorbidity during pregnancy. Hypertension during pregnancy accounts for a substantial maternal and perinatal morbidity and mortality risk. In our review we focus on the forms, diagnosis and therapeutic possibilities of gestational hypertension according to the European and domestic guidelines.]

[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.]

[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.]

Oxidative stress has been associated as an essential contributor to the development of neurodegenerative diseases. Recent developments in the field of Parkinson’s Disease (PD) pathophysiology have led to a renewed interest in this field. As an antioxidant, uric acid (UA) has arisen as a potential neuroprotectant. Higher concentrations of UA are linked to reducing the risk of the development of the disease and preventing its progression. However, the expositions are unsatisfactory because the outcomes of these reports have not been consistent. This study is set out to assess the association of whether lower UA concentrations increased the PD risk by investigating its relationship with patients’ demographic and clinical data, and to determine whether previous studies are compatible with the Turkish-sampled population. Furthermore, we aimed to determine UA’s probability of being an early-stage diagnostic marker. A total of 305 patients and 100 healthy controls were included. Serum UA levels of patients and controls were compared with clinical features. We classified the patients into three motor subtypes and determined the disease severity by modified Hoehn&Yahr Staging Scale (mH&Y) and Unified Parkinson’s Disease Rating Scale (UPDRS). Standardized Mini-Mental State Examination (MMSE-TR) was assessed for cognition. There were not any significant differences of age and sex between patients and controls (p=0.030, p=0.132). The mean UA was 5.06±1.33 mg/dL in patients and 5.46±1.44 in controls, and a statistical significance was detected (p=0.022). The mean MMSE-TR were 24.83±4.35 in patients and 27.09±2.13 in controls, and statictical significance was revealed (p=0.001). The mean duration of the disease was 6.31±4.16 years, mean UPDRS scores were 59.74±22.33, and mH&Y scores were 2.29±0.91. In binary comparisons, patients with tremor-dominant motor subtype had lower UA concentrations than controls (p=0.014). ROC curve analysis revealed UA’s cut-off as ≤9.15, the specificity was 99.3, the sensitivity was 10.0, and the area under the curve was 0.576 (p<0.005). Regression analysis revealed age as an independent risk factor on UA values. Oxidative stress might be a factor in the development of PD, and UA may be a possible prospective protecting factor in the clinical course of the disease. However, it does not affect the severity. Our results support that lower uric acid concentrations are associated with PD; however, it is not a powerful indicator for predicting PD risk. As we reveal more about UA and its effect in further investigations, its significant role will become well-defined.

[Benefits of SGLT-2 inhibitors: beyond glycemic control]

BALOGH Zoltán, SIRA Lívia

[In the recent years, according to international and Hungarian guidelines, in addition to lifestyle modification, metformin is the preferred initial glucose-lowering drug for most people with type 2 diabetes, if not contraindicated. Sodium glucose co­transporter-2 inhibitors have been shown to reduce progression of chronic kidney disease, or kidney failure, as well as the risk of hospitalizations for congestive heart failure and (mainly in secondary prevention) cardiovascular death in patients with type 2 diabetes. For major adverse cardiovascular events and for the renoprotection, there seems to be no class effect. On the other hand, a class effect of sodium glucose co­transporter-2 inhibitors is evident for hospitalization for heart failure. In this review the authors summarize novel data about sodium glucose cotransporter-2 inhibitors, and about their new perspectives in the near future.]

[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.]
