[Prevalence of renal anaemia due to insufficient production of erythropoietin increases progressively in the course of renal function deterioration. Renal anaemia is treated by erythropoesis stimulating agents (ESA). Outcomes of randomized clinical trials have taught us to avoid the strategy of normalization of hemoglobin (HGB) levels by ESA therapy as it may increase the risk of cardiovascular events and mortality. The Kidney Disease: Improving Global Outcomes (KDIGO) Clinical Practice Guideline for Anaemia published in 2012 recommends to start ESA therapy in the 90-100 g/l HGB range and suggests to keep HGB concentrations below 115 g/l. It is an inappropriate strategy to aim at normalizing hemoglobin (HGB) levels by ESA therapy because it may lead to progressive escalation of ESA doses even in the presence of diminished ESA responsiveness. High ESA doses and diseases causing ESA hyporesponsiveness eg. infections, chronic inflammation, malnutrition, insufficient dose of dialysis, severe hyperparathyroidism, iron deficiency are related to increased risk of mortality. KDIGO Clinical Practice Guideline for Anaemia emphasizes the importance of assessing and treating causes of ESA hyporesponsiveness, limits ESA dose escalation and recommends gradually changing ESA doses to avoid high amplitude HGB oscillation.]

[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).]

[Goals, doubts and confidences in treatment of renal anemia]

KISS István, SZEGEDI János, KULCSÁR Imre, DEÁK György, KISS Zoltán, REMPORT Ádám, AMBRUS Csaba

[The authors sum up the physiology of erythropoiesis, the history of the erythropoietin’s discovery and the steps through which it became applicable to clinical adaptation. The biologically similar erythropoietin medicines and their application are reviewed. The setting of the target hemoglobin value and the weekly amount of erythropoietin needed for successful therapy are briefly surveyed. The authors draw attention to the fact that by increasing the dose the risk of mortality rises. Considering the other side effects they conclude based on international data and studies that “less is more” in this case namely the lower target value and erythropoietin dose can mean bigger therapeutic success. The erythropoietin treatment’s practice in Hungary is expressly efficient in the authors’ view.]

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


[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.]

[Managing hypertension using a fixed combination of an angiotensin converting enzyme inhibitor and a calcium channel blocker]

E. Chazova, G. Ratova, V. Nedogoda, M. Lopatin, B. Perepech, V. Tsoma

[The objective of the study was to compare the efficacy of a low-dose combination of an angiotensin-converting enzyme (lisinopril 10 mg) and a dihydropyridine calcium channel blocker (amlodipine 5 mg) (Ekvator, Gedeon Richter) (Group 1) and enalapril with or without hydrochlorothiazide (Group 2) in hypertension. Materials and methods: The study included 93 patients with hypertension (36% of men and 64% of women). The mean age was 52.6±12 years and the mean duration of hypertension was 7.5±6.1 years. The initial office blood pressure (BP) was 149.2±13.8/91.4±81 mmHg. Patients were randomized into two groups (Group 1, n=51 and Group 2, n=36). Results: The fixed-dose combination of amlodipine/lisinopril offered the potential to reduce the office BP by -28.9±11.3/-16.0±8.7 mmHg; p<0.0001. In Group 2 the office BP dropped by -22.9±17.9/-11.5±10.7 mmHg; p<0.0001. Patients in Group 1 achieved goal blood pressure more frequently than patients in Group 2 (94.1% versus 72.2% patients respectively; p=0.008). There were no significant changes in the heart rate in either group. The reduction of microalbuminuria (the reduction in urinary albumin excretion (UAE)) by -13.8±24.4 mg/24h (p<0.001) was observed only in patients from Group 1. The quality of life of patients from Group 2 improved. However, the quality of life improvements were more significant in Group 1 than in Group 2 (p=0.002). Conclusion: The fixed-dose combination of amlodipine/lisinopril offers the potential to achieve a target blood pressure in 94% of patients with hypertension, produces a nephroprotective effect and improves patients’ quality of life.]

[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.]

Risk factors for ischemic stroke and stroke subtypes in patients with chronic kidney disease

GÜLER Siber, NAKUS Engin, UTKU Ufuk

Background - The aim of this study was to compare ischemic stroke subtypes with the effects of risk factors, the relationship between grades of kidney disease and the severity of stroke subtypes. Methods - The current study was designed retrospectively and performed with data of patients who were hospitalised due to ischemic stroke. We included 198 subjects who were diagnosed with ischemic stroke of Grade 3 and above with chronic kidney disease. Results - In our study were reported advanced age, coronary artery disease, moderate kidney disease as the most frequent risk factors for cardioembolic etiology. Hypertension, hyperlipidemia, smoking and alcohol consumption were the most frequent risk factors for large-artery disease. Female sex and anaemia were the most frequent risk factors for small-vessel disease. Dialysis and severe kidney disease were the most frequent risk factors in unknown etiologies, while male sex, diabetes mellitus, prior stroke and mild kidney disease were the most frequent risk factors for other etiologies. National Institute of Health Stroke Scale (NIHSS) scores were lower for small-vessel disease compared with other etiologies. This relation was statistically significant (p=0.002). Conclusion - In order to improve the prognosis in ischemic stroke with chronic kidney disease, the risk factors have to be recognised and the treatment options must be modified according to those risk factors.

[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.]

[Recommendation for the treatment of hyperlipidemia in chronic renal disease]


[The incidence of chronic kidney disease continuously increases worldwide. Studies suggest that kidney disease is an as powerful cardiovascular risk factor as diabetes mellitus. Because of the high prevalence of lipid disorders, it is likely that dyslipidaemia plays a major role in the high cardiovascular risk of these patients. Evidence supports treating dyslipidaemia in patients with mild or moderate kidney disease, but the results of statin trials in dialysed patients are inconclusive. A practical treatment algorithm is proposed considering the special aspects, the effectiveness and safety of the drugs in the whole spectrum of kidney disease.]
