[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.]

[Kidney diet and the patient compliance issue ]

LADÁNYI Erzsébet

[There have been significant developments in the field of nephrology and dialysis as for the science and technology are concerned in the past decades. However, CKD patients still show high mortality and morbidity. From among the several factors determining the long-term outcome of CKD patients metabolic disorder and malnutrition play an important role. Malnutrition is often not diagnosed or is not paid enough attention to in the complex treatment of CKD patients. It is important to make both the patients and clinical staff more aware of proper nutrition and importance of prevention and treatment of malnutrition, respectively. The early diagnosis and treatment of malnutrition is of utmost importance in CKD patients. The long term renal failure and the accompanying malnutrition have a negative impact on their long term outcome and quality of life. Since the malnutrition causes a lot of complications, it is indispensable for dietitians and nephrologists to work closely together. Patient compliance is a determining factor in the successful implementation of renal diet.]

[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.]

[Serum uric acid level in hypertension. Domestic experience based on the data of the Hungarian Hypertension Registry 2011., 2013. and 2015. Part III. - Relation of uric acid to clinical and laboratory characteristics]

KÉKES Ede, PAKSY András, ALFÖLDI Sándor

[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.]

[NEUROVASCULAR COMPRESSION IN THE MEDULLA OBLONGATA AS A CAUSE OF RESISTANT HYPERTENSION - THOUGHTS APROPOS OF A PATIENT]

KOVÁTS László, BRETUS Angelika, CSUTAK Kinga, NAGY Gyöngyi, GASZTONYI Beáta

[INTRODUCTION - The vasomotor centre, the central regulator of the cardiovascular system, is localised in the rostral ventrolateral medulla oblongata. Irritation of this area and/or of the ninth and tenth cranial nerves (that are involved both in the afferent and efferent pathways of the baroreceptor reflex) causes sympathetic hyperactivity, which in some cases leads to severe resistant hypertension. A common underlying cause of this is pulsatile neurovascular compression, a vascular malformation rarely sought for. CASE REPORT - The authors present the case of a middle-aged woman with what had been considered “essential” hypertension. Magnetic resonance angiography showed vascular compression of the medulla oblongata and the departing left ninth and tenth cranial nerves as the cause of her hypertension. CONCLUSIONS - After a literature review the authors draw the attention to this rarely identified cause of resistant hypertension and to the difficulties of its diagnosis.]

[Prognostic significance of invasion in glioblastoma]

SZIVÓS László, VIRGA József, HORTOBÁGYI Tibor, ZAHUCZKY Gábor, URAY Iván, JENEI Adrienn, BOGNÁR László, ÁRKOSY Péter, KLEKNER Álmos

[Glioblastoma is the most common malignant CNS tumor, its surgical removal is hindered by the tumors invasive nature, while current anti-tumor therapies show limited effectiveness – mean overall survival is 16-24 months. Some patients show minimal response towards standard oncotherapy, however there are no routinely available prognostic and predictive markers in clinical practice to identify the background of mentioned differences in prognosis. This research aims to identify the prognostic significance of invasion-related extracellular (ECM) components. Patient groups with different prognoses were created (OS: group A <16 months, group B > 16 months), and internationally recognized prognostic markers (IDH1 mutation and MGMT promoter hyper-methylation) were tested in the flash-frozen tumor samples. Furthermore, the mRNA levels of 46 invasion-related ECM molecules were measured. Clinical data of the patients who have been operated on at the University of Debrecen Clinical Center Department of Neurosurgery and treated at the Department of Clinical Oncology showed no significant differences except for survival data (OS and PFS), and reoperation rate. All samples were IDH wild type. MGMT promoter hypermethylation rate showed significant differences (28.6% vs 68.8%). The expressional pattern of the invasion-related ECM molecules, i.e. the invasion spectrum also showed major differences, integrin β2, cadherin-12, FLT4/VEGFR-3 and versican molecules having signficantly different mRNA levels. The accuracy of the inivasion spectrum was tested by statistical classifier, 83.3% of the samples was sorted correctly, PPV was 0.93. The difference found in the reoperation rate when comparing different prognostic groups aligns with literature data. MGMG promoter region methylation data in Hungarian samples has not been published yet, and further confirming current knowledge urges the implementation of MGMT promoter analysis in clinical practice. Studying the invasion spectrum provides extra information on tumors, as a prognostic marker it helps recognizing more aggressive tumors, and calls attention to the necessity of using anti-invasive agents in GBM therapies in the future.]

[Isolated systolic hypertension in the elderly and very elderly]

FARSANG Csaba

[In the elderly (˃65 yrs) and very elderly (˃80 yrs) large clinical investigations showed that isolated systolic hypertension is the most frequent form of hypertension. In the background, several cardiovascular, neural and hormonal changes have been proved. One of the most important pathogenetic factor is the increase of arterial stiffness. This leads to the increase of pulse wave velocity and systolic blood pressure, and also to the decrease of diastolic blood pressure. Consequently, pulse pressure increases. All these factors contribute to the increase in incidence and prevalence of cardiovascular consequences of hypertension, which are more frequent than in younger ages.]

The evaluation of the relationship between risk factors and prognosis in intracerebral hemorrhage patients

SONGUL Senadim, MURAT Cabalar, VILDAN Yayla, ANIL Bulut

Objective - Patients were assessed in terms of risk factors, hematoma size and localization, the effects of spontaneous intracerebral hemorrhage (ICH) on mortality and morbidity, and post-stroke depression. Materials and methods - The present study evaluated the demographic data, risk factors, and neurological examinations of 216 ICH patients. The diagnosis, volume, localization, and ventricular extension of the hematomas were determined using computed tomography scans. The mortality rate through the first 30 days was evaluated using ICH score and ICH grading scale. The Modified Rankin Scale (mRS) was used to determine the dependency status and functional recovery of each patient, and the Hamilton Depression Rating Scale was administered to assess the psychosocial status of each patient. Results - The mean age of the patients was 65.3±14.5 years. The most common locations of the ICH lesions were as follows: lobar (28.3%), thalamus (26.4%), basal ganglia (24.0%), cerebellum (13.9%), and brainstem (7.4%). The average hematoma volume was 15.8±23.8 cm3; a ventricular extension of the hemorrhage developed in 34.4% of the patients, a midline shift in 28.7%, and perihematomal edema, as the most frequently occurring complication, in 27.8%. Over the 6-month follow-up period, 57.9% of patients showed a poor prognosis (mRS: ≥3), while 42.1% showed a good prognosis (mRS: <3). The mortality rate over the first 30 days was significantly higher in patients with a low Glasgow Coma Scale (GCS) score at admission, a large hematoma volume, and ventricular extension of the hemorrhage (p=0.0001). In the poor prognosis group, the presence of moderate depression (39.13%) was significantly higher than in the good prognosis group (p=0.0001). Conclusion - Determination and evaluation of the factors that could influence the prognosis and mortality of patients with ICH is crucial for the achievement of more effective patient management and improved quality of life.

[Hungarian dialysis statistics: changing trends in the renal epidemiology]

KULCSÁR Imre, KISS István, SZEGEDI János

[In the last 30-35 years, dialysis care in Hungary has been a major development: both the incidence and prevalence of patients have increased year by year. Over the last decade, growth has slowed and is becoming more and more stabilized (similar trends can be seen in dialysis statistics in developed countries). Behind the dialysis indication the acute kidney injury (AKI) is more common than the end-stage renal disease (ESRD). The latter incidence has been stable for last 6 years (200-230 patient/million population). The annual average growth rate of prevalent dialysis patients was only 0.9%/year in the last 6 years. Among prevalent dialysis patients, the proportion of diabetic patients has remained unchanged for 10 years (26-27%), but those have increased who had hypertension nephropahty. The average age of incident and prevalent dialyzed patients has decreased gradually over the past 8 years (between 2009 and 2017 incident rate was from 67.1 to 63.0 years, prevalent rate was from 65.6 to 61.8 years). Unfortunately, just over half of the patients who dialyzed due to chronic kidney disease (CKD) have reached dialysis day 91. This is due to the high proportion of patient who was in urgent need of dialysis. In chronic hemodialysis (HD) program, the proportion of patients treated with arterovenous fistulas (AVF) decreases, while the rate of central venous catheter (CVC) users increases. The Hungarian peritoneal dialysis program in Europe is very good. The number of prevalent patients receiving renal replaement therapy (RRT) in Hungary in 2017 was 1005 for 1 million inhabitants.]
