Hypertension and nephrology - 2015;19(02)

[Hypertension guidelines published by various societies in the previous year follow two distinct trends regarding recommendations about treatment. The European Society of Hypertension and the European Society of Cardiology (ESH/ESC) gives the clinician free hand to select the antihypertensive drug, mentioning the optimal treatment regime for various associated clinical conditions. Guidelines published by the American Society of Hypertension and the International Society of Hypertension (ASH/ISH) or by the Eighth Joint National Committee (JNC8) are far less permissive, recommend the first drug of choice from a narrower circle of antihypertensive agents and describe the initiation and escalation of therapy in algorithms. This article displays some of the corresponding and disparate recommendations of the three guidelines.]

[Diagnosis of hypertension and target levels in mirror of the newest recommendations]

STUDINGER Péter, BARNA István

[In the past year, many societies published new recommendations in the field of hypertension. The European Society of Hypertension and the European Society of Cardiology (ESH/ESC) published a comprehensive guideline in July 2013, providing an elaborate description of the diagnosis of hypertension. The clinical practice guideline of the American Society of Hypertension and the International Society of Hy per - tension (ASH/ISH) contains a brief set of recommendations, and explains the diagnostic approach to hypertension in a less detailed manner. The Eighth Joint National Committee (JNC8) focuses on certain aspects of hypertension using rigorous evidence- based methodology. This article displays some of the corresponding and disparate recommendations of the three guidelines.]

[Tubulointerstitial nephritis and uveitis syndrome]

BAJCSI Dóra, FEJES Imre, KEMÉNY Éva

[Tubulointerstitial nephritis and uveitis (TINU) syndrome is a rare and underdiagnosed oculorenal disorder that is characterized by the development of acute tubulointerstitial nephritis and uveitis. The median age of onset is 15 years, but it may occur at any age. There is a female predominance. Uveitis might occur before, after, and also concomitantly with tubulointerstitial nephritis. The symptoms are typically non-specific, including fever, loss of appetite, weight loss, nausea and vomiting, weakness, abdominal pain, arthralgias and myalgias. Laboratory findings reveal an acute impairment of renal function, anaemia and elevated inflammatory parameters. Urinary findings are consistent with tubulointerstitial nephritis including subnephrotic proteinuria, sterile leucocyturia, microhaematuria, and tubular dysfunction (e.g. normoglycemic glycosuria). The prognosis appears to be good, especially in children. Persistent renal dysfunction only develops in a small proportion of cases. In this paper, we present the case of a 39-year-old female patient with TINU syndrome, and review the literature.]

[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.]

[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.]

[Monitoring of the blood pressure lowering effectiveness of ramipril-amlodipine fix combination – a non-interventional trial (RAMONA study)]

TOMCSÁNYI János

[Purpose: Monitoring the effectiveness and safety of the fix combination formulation Egiramlon® therapy containing ramipril and amlodipin in patients, suffering from mild or moderate hypertension despite antihypertensive treatment. Patients and methods: Open, prospective, phase IV clinical observational study, which involved 9169 patients (age >18) with mild or moderate hypertension [TUKEB No: 16927- 1/2012/EKU (294/PI/12.)]. Ramipril/Amlodipin 5/5, 5/10, 10/5, 10/10 mg combinations were administered/ titrated in three visits, during the four months period according to the physician’s decision Blood pressure was measured by validated blood pressure sphygmomanometry and ABPM (Meditech, Hungary). The dosis of the fix combination formulation was determined individually during the visits by the 923 doctors involved in the study. The target blood pressure value was 140/90 mmHg, but in case of high risk patients population (diagnosed cardiovascular disease, diabetes), 130/90 mmHg target value was determined. Results: In 70.1% of the patients had no protocoll deviation. Patients data and examination results were processed according to this 6423 patient population. The average age of the patients were 60.2 year, in 50-50% sex distribution. The average duration of the treated hypertension was 9.8 years and the average blood pressure value was 157/91 mmHg. Till the end of the study, systolic blood pressure has decreased with 26.4 mmHg and diastolic pressure with 11.8 mmHg. An average 5.5 bpm heart rate frequency decreasing was observed at the end of the study. As a result of the treatment 52.4% of the patient population has reached the target blood pressure value.]

[Sudden death – ECG – hypertension]

KÉKES Ede

[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.]
