[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.]

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


[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.]

[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.]

[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]


[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.]

[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.]

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


[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.]

[Therapy of isolated systolic hypertension III.]


[In the elderly and very elderly (˃80 yrs), a wealth of data from large clinical trials are available, showing the necessity of treatment mostly with drug combinations - fix-combinations are preferred for increasing the adherence/persistence to therapy. Using diuretics, ACE-inhibitors/ARBs with calcium antagonists, and in special cases diuretics and beta blockers are also suggested by recent European guidelines (ESH, HSH). The target is <140 mmHg, but in octogenarians <150 mmHg. Some studies are pressing for even lower SBP (to around 120 mm Hg), but it seems to be wise to balance advantages/disadvantages, so the optimal SBP may be around 130 mmHg.]

[Changing tendencies in retinal surgery]


[Retinal detachment, a disease caused by pathologic alteration of the vitreoretinal relationship, may decrease vision to blindness without treatment. Although some of the patients with retinal detachment become blind for the time being, last two decades produced significant improvement both in diagnosis and treatment. As a result of new surgical techniques we can perform successful surgery even in cases that were earlier inoperable. Recent methods are significantly less traumatic to the eye than they were 20 years ago. Dramatically reduced bedrest before and after surgery, regional or even topical anaesthesia instead of general anaesthesia, short term hospitalisation or one day surgery, short term restriction of physical activity after surgery are the most important consequences of the new wave of retinal detachment repair. According to recent recommendations of the prophylactic treatment of peripheral retinal lesions we treat only horse tears with sudden retinal complaints.]

[The relevancy of measuring the level of D-dimer test in clinical practice]


[Plasma levels of D-dimer may rise in a number of pathological conditions, which might be relevant for diagnosis as well as for prognosis. Its concentration increases with age, perhaps because of the wide-spread co-morbidity. In this article we demonstrate the diagnostic role of Ddimer in the well-known thromboembolic diseases. Beyond that, we highlight the importance of measuring D-dimer levels in other, lesser-known conditions, about which important findings have been published, such as cardiovascular, inflammatory or malignant diseases. It seems that in these disorders - provided that appropriate clinical conditions are available -, measuring D-dimer levels might have a role not only in diagnosis but in the prognosis as well. Furthermore, our aim was to discourage inappropriate clinical practice. Ignoring to measure the D-dimer levels (for fear of it being high) might lead to diagnostic errors. On the other hand, routinely performing the D-dimer test without clinical consideration (in the hope of it being negative) might cause diagnostic confusion in case of unexpected positivity and - mostly because of false interpretation - lead to further, unnecessary examinations.]

[Hypertension and diabetes mellitus]

SZEGEDI János, KISS István

[Hypertension and diabetes mellitus are endemics which affect large crowds; they play an important role in the morbidity and mortality of the population. Both diseases are cardiovascular risk factors, their co-occurrence increases the coronary risk. According to forecasts, there will be 60% increase in the number of hypertensive patients by 2025; it will affect 29% of the world’s adult population, 1.56 billion people. The number of patients with diabetes increases in all countries; 552 million diabetic patients should be expected by 2030. The simultaneous occurrence of both diseases may be a coincidence, but there is also causal relationship between the two diseases (diabetic nephropathy, metabolic syndrome). The two diseases often occur in endocrine diseases, and in connection with medicinal therapy (steroids, etc.). The simultaneous occurrence of these two diseases determines the therapeutic strategy. During the prevention and treatment of both diseases, the change in lifestyle has an important role (obesity, salt intake, physical activity).]
