[Antihypertenive effect of rilmenidine. Evaluation of the Hungarian multicenter VERITAS study]


MAY 20, 2017

Hypertension and nephrology - 2017;21(03)

[The VERITAS study showed that in hypertensive patients the imidazoline I1 receptor agonist, rilmenidine significantly decreased the office blood pressure as well as the blood pressure measured by ambulatory blood pressure monitoring (ABPM). The white-coat reaction and left ventricular hyperthrophy (LVH) were also decreased. Ain a separate study involving hypertensive subjects rilmenidine significantly increased baroreflex sensitivity. This effect may contribute - mainly during daytime - to the antihypertensive effect.]

[Systemic ANCA-associated vasculitis. Induction immunosuppression therapy, complications and outcome. Part 1]

HARIS Ágnes, POLNER Kálmán

[The present review is compiled of two parts, the first part aims to summarize the induction immunosuppressive therapy, the second part delineates the outcome and complications of ANCA-associated vasculitis. ANCA-associated vasculitis is a systemic disease, accompanied with rapidly progressive glomerulonephritis and severe, often life-threatening extrarenal complications. By early diagnosis and immediate initiation of immunosuppressive therapy, both patient and renal outcome have been substantially improved. The major aims of modern therapeutic protocols are, besides improving survival, to decrease immunosuppressive drug toxicity and avoid infections. Immunosuppression is based on the combination of large dose of corticosteroid and cyclophosphamide, which is advisable to supplement by plasma exchange. The B-cell depleting anti-CD20 monoclonal antibody rituximab, which has already been available in Hungary, has been proved to be similarly effective in newly diagnosed ANCA-vasculitis, and even more effective in a relapsing disease, compared to cyclophosphamide. Amongst rituximab’s further indications in this disease is the preservation of young women’s fertility, and it also has priority in some other special cases. Early diagnosis and prompt immunosuppressive treatment have resulted that ANCAvasculitis became a treatable disease with reasonably good clinical outcome, yet both the disease and the immunosuppressive medications frequently cause complications, which necessitate continuous alertness of the attending nephrologists.]

[Isolated systolic hypertension in children and young adults I.]


[Prevalence of the isolated increase in systolic blood pressure ≥140 mmHg with normal or low diastolic blood pressure ≤80 mmHg, is defined as isolated systolic hypertension. Its prevalence increases with age up to >90% in patients aged >90 years. Isolated systolic hypertension is also found in the young and the clinical significance of it is still debated. For the therapy, those drugs should be used which have a license for use in children: angiotensin converting enzyme inhibitors, angiotensin AT-1 receptor antagonists, calcium channel blockers beta-blockers and diuretics and their combinations. The young adults with isolated systolic hypertension had a much higher risk of dying from coronary heart disease or cardiovascular disease, then the normotensive individuals, and should be treated to normalise their blood pressure. 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 when needed diuretics and beta-blockers are suggested by recent European guidelines. 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.]

[Prevalence of isolated systolic hypertension in our country]

KÉKES Ede, BARNA István, DAIKI Tenno, DANKOVICS Gergely, KISS István

[Prevalence of hypertension over the age of 56 is increasing in size and a significant proportion (60-80%) of isolated systolic hypertension. Within the population screening in the older age groups - in the light of economic development - 25-40% of the prevalence. We have an opportunity to analyse the prevalence and specificity of isolated systolic hypertension from age 36 to age 10 years on the base of 7 years data of the MÁESZ (Comprehensive Health Protection Screening Program of Hungary 2010- 2020) survey. Between 56-65 years 23.27-24.23% (male/female) 66-75 years 34,89-33,15% and over 76 years 44.04-41.5% occurrence was found. Divergence of systolic and diastolic pressure has begun since 36 years. Pulse pressure was used to separate individuals with varying degree of vascular disorders.]

[Prognostic significance of stiffness index determined by digital volume pulse method in polycystic kidney disease]

SÁGI Balázs, KÉSŐI Bence, KÉSŐI István, VAS Tibor, CSIKY Botond, NAGY Judit, KOVÁCS Tibor

[Introduction: It is known from previous studies, that in chronic renal failure cardiovascular mortality and morbidity are more frequent than in the general population. The prognostic significance of arterial stiffness on cardiovascular outcomes trials was first demonstrated in end-stage renal disease patients by epidemiological longitudinal studies. Our aim was to assess the prognostic significance of arterial stiffness in polycystic kidney disease. Methods: 55 patients with polycystic kidney disease (PKD) were examined and followed in our clinic. Pulse wave velocity was determined by digital volume pulse (DVP) method, and a so-called stiffness index (SI DVP) was calculated. MDRD formula was used for estimating the glomerular filtration rate (eGFR, mL/min/1.73 m2) to determine renal function. Patients were observed regularly, in every 3-6 months, and we checked lab tests, which assessed the patient’s renal function and cardiovascular events occurred in patients were collected in our outpatient department. Results: Our study involved 55 patients, 21 were male, the mean age was 45±12 years. The average follow-up was 63±32 months. The average value of the stiffness index was 11.11±2.22 m/s. We divided the patients by 11 m/s as cut off point of SI values into two groups and analysed their outcome. In the increased arterial stiffness group (SI >11 m / s) the probability of the combined endpoint occurrence was signi - fi cantly higher than in the group with flexible arteries (χ-square: 4.571; p=0.033). Between the two groups we did not found significant difference in cardiovascular endpoint, but we found a statistically significant difference between the two groups in renal outcomes (χ-square: 5.591; p=0.018). Conclusion: In polycystic kidney disease the increased arterial stiffness may predict the onset of end-stage renal failure. Digital Pulse volume as determined by Pulse Trace system appears an appropriate method for making prognosis in chronic kidney disease.]

[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.]

[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.]

[Notes on the management of hypertension in chronic kidney disease ]


[The prevalence of hypertension among pa­tients with chronic kidney disease is high, reaching more than 80%. Hypertension is both one of the main causes and also the most common consequence of chronic kidney disease. It is also a main factor responsible for the high cardiovascular morbidity and mortality in this patient population. Blood pressure control can improve patient outcomes, lower cardiovascular risk and slow down the progression of kidney dis­ease, irrespective of the underlying cause. The optimal therapy should therefore focus not only on blood pressure reduction but also on renoprotection. Basic understanding of the renal pathophysiology in hypertension and renal effects of various medications is of paramount importance. In this review, we summarized cornerstones of the antihypertensive therapy in patients with chronic kidney disease. The management of patients receiving kidney replacement therapies, such as hemodialysis, peritoneal dialysis or transplanta­tion requires special knowledge and expe­rience, therefore it is not discussed here. The aim of this review was to allow non-nephrologist physicians to take care of their kidney patients with more confidence and effectiveness.]

[The importance of assessing subclinical organ damage in risk prediction of hypertensive patients]

GODINA Gabriella, JÁRAI Zoltán

[As the cardiovascular risk influences the quality and intensity of blood pressure lowering therapy, the goal blood pressure values and the frequency of medical control of hypertensive patients, as well as global risk assessment has an important role in the management of hypertension. In the last couple of years many data have been accumulated showing the poor prognostic value of traditional cardiovascular risk factors. This is the reason why recent Hungarian and international guidelines on the management of hypertension advise the screening for subclinical organ damage. Our goal was to summarize the importance of subclinical organ damage by discussing recently published literature on this topic. An overview has been made on the markers of vascular subclinical damage, like carotid atherosclerosis proved with carotid ultrasonography, peripheral arterial disease assessed with ankle-brachial pressure index measurements and vascular rigidity defined with pulse wave velocity measurements. The prognostic values of myocardial hypertrophy assessed with ECG and/or echocardiography and renal damage proved with decreased estimated glomerular filtration rate and proteinuria are also discussed. Summing up what has been said so far, the assessment of subclinical organ damage has a role in cardiovascular risk prediction, however more randomized and prospective studies have to be performed to define the most suitable (i.e. the most reliable and the most cost-effective) markers for this purpose.]

[The effects of angiotensin receptor blockers on the nervous system in hypertension and dementia]


[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.]
