Hypertension and nephrology - 2010;14(05)

[Accelerated cardiovascular disease is a frequent complication of chronic kidney disease. Chronic kidney disease promotes hypertension and dyslipidaemia, which in turn can contribute to the progression of renal failure. Diabetic nephropathy is a leading cause of renal failure. Hypertension, dyslipidaemia and diabetes together are the major risk factors of the development of endothelial dysfunction and progression of atherosclerosis. Inflammatory mediators are often elevated and the renin-angiotensin system is frequently activated in chronic kidney disease. Promoters of calcification are increased and inhibitors are reduced, which favors vascular calcification, an important cause of vascular injury associated with end-stage renal disease. Accelerated atherosclerosis will then lead to increased prevalence of coronary artery disease, heart failure, stroke and peripheral arterial disease.]

[Dialysis in Hungary: 2003-2009]

KULCSÁR Imre, SZEGEDI János, LADÁNYI Erzsébet, TÖRÖK Marietta, TÚRI Sándor, KISS István

[The authors show the data of Hungarian dialysis statistics from 2003 to 2009. The questionnaire-based data collection was made by the Dialysis Committee of the Hungarian Society of Nephrology. The number of all patients entered in the dialysis program increased by 45.2% over six years (an average of 7.5% per year) and the number of new ones increased by 51.2% (8.5% per year). The increase in number of patients treated with haemodialysis was 39% (6.5% per year) in this period. The increase in the number of patients in the peritoneal dialysis program was extremely high: 80.6% (an average of 13.4% per year). The population incidence of new dialysed patients was 332/1 million in 2003 and 483/1 million in 2009. The population point prevalence at the end of the year was 437/1 million in 2003, but 607/1 million in 2009. The penetrance of peritoneal dialysis was 12.8% in 2009. Differences exist among the regions of Hungary in the number of patients, the penetrance of peritoneal dialysis and the prevalence of renal replacement therapies. Among patients suffering in conditions which lead to end stage renal disease the proportion of patients with diabetic or hypertensive nephropathies is increasing and the proprtion of patients with glomerular or tubulointerstitial damage is decreasing. The number (and rate) of the elderly people is growing continuously year by year. The rate of patients on waiting list for renal transplantation is decreasing (the rate was 20% in 2003, but only 10.7% in 2009). There is also a slow decrease in the number of the annual renal transplantations. The mortality rate of chronically dialysed patients shows a little increase. Five dialysis centres for paediatric patients and 58 for adults have been functioning in Hungary by the end of 2009. In average 106 patients have been treated by each Hungarian dialysis centre in contrast to the optimal of 60 persons. The number of nephrologists increased between 2003 and 2007, but slightly decreased since then. The case is similar regarding nephrological nurses.]

[Recent developments in the diagnosis and therapy of haemolytic uremic syndrome. Part 1: Diagnosis and initial therapy]

PROHÁSZKA Zoltán, SZILÁGYI Ágnes, SZABÓ Melinda Zsuzsanna oh., RÉTI Marienn, REUSZ György

[In this summary an overview is offered on the recent developments of the investigation and the treatment of hemolytic uremic syndrome. Based on the recent developments in the understanding of the pathogenesis and on the novel diagnostics there is an increasing ability to identify the etiology of specific diagnostic sub-groups of the disease. This molecular etiology-based classification and sub-group diagnosis has substantial influence on the short-term and long-term management of the affected patients. The first part of our review focuses on the steps of first and second line diagnosis and the selection between available therapeutic options, and provides flow-charts for the daily work. The various aspects of the long-term management and disease monitoring in hemolytic uremic syndrome will be reviewed in a second article in the future.]

[Kidney transplantation in Hungary, 2010]


[Hungarian kidney transplantation has been established with three milestone operations. In 1902 Emerich Ullmann showed the technical feasibility of renal transplantation on dogs, and later the living donor transplant of András Németh in 1962 and the program starting operation of Ferenc Perner in 1973 already meant the real possibility for Hungarian patients. More than 5000 kidney transplantations were done since, and the operations are now made at the four university medical schools centers. In 2009 248 renal transplantations were done in our country (Budapest: 148, Szeged: 51, Pécs: 39, Debrecen: 34), from which 24 were living donor and nine combined kidney-pancreas cases. Despite the worsening financing situation in the health care system the numbers of transplantations are stable within a 15 year period, but this means a marked decrease in international comparison. In our country, the ratio of living donation is low, there is no paired donation, incompatible transplantation, the problems of hypersensitive patients are unresolved, and there is no old-for-old program. The solution to all of these problems could be joining to Eurotransplant, which is the definite wish of the transplant society based on the positive Slovenian and Croatian examples.]

[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.]

[County level mortality data of urogenital system in Hungary between 2010-2014]

KISS István, PAKSY András

[According to The International Statistical Classification of Diseases and Related Health Problems (10th Revision, ICD 10; XIV), urogenital diseases resulted in an average 910 yearly deaths in Hungary from 2010 through 2014, less than 1% of the cumulative mortality rate. Out of all urogenital conditions, kidney and bladder diseases were the leading cause of death, accounting for nearly 85 percent of all deaths in the examined period. It should be noted that mortality due to urogenital cancers, renovascular hypertonia, diabetic nephropathy, congenital malformations and pathologies related to childbirth and pregnancy are excluded from consideration in the present review. As the Hungarian Central Statistical Office does not disclose the causes of death by age and gender at its county-level data, this paper reports gender-specific mortality rates. Due to the fact that the county-level mortality rate of urogenital diseases is low and the yearly standard deviation is high, the five-year overall mortality rate of 2010-2014 is presented. Hungarian counties differ greatly in terms of mortality from urogenital diseases. The number of deaths per 100 000 population ranges between 6.74 in Békés county and 16.38 in Fejér county. Counties within the same region may exhibit substantially different mortality rates. An overall 7.01 deaths per 100 000 population was reported in Győr-Moson-Sopron county, whereas among residents of the neighbouring Vas county the rate was reported as 14.73 per 100 000 population. The observed variations prevail even when standardised mortality rates are compared and thus the differences in the counties’ age distributions are accounted for. Regional differences become more apparent when only the deaths caused by kidney diseases are analysed out of all urogenital pathologies. In this case, two- or threefold differences are observed between the respective Hungarian counties. Major disparities are still present between counties within the same region. For example, the number of deaths per 100.000 population is 3.74 in Hajdú-Bihar county, and 8.04 in Jász-Nagykun-Szolnok county, respectively. The diagnosis frequency of kidney diseases has a strong positive correlation with case fatality, but it may not fully account for all regional variations in mortality rates. Regional characteristics of dialytic care and the accessibility of dialytic facilities is not related to patient mortality. ]

Clinical Neuroscience



[Chlamydia pneumoniae has recently been implicated in the pathogenesis of several neurological diseases. As an intracellular parasite with its unusual life cycle it is able to circumvent the immune system and to persist in the organism. It has the ability to modify the function of the infected cell and supposedly induce autoimmune reactions. These properties can make it pathogenic in several chronic neurological diseases including multiple sclerosis, atherosclerosis, stroke, Alzheimer dementia and giant cell arteriitis. The evaluation of the available, often contradictory, data that are based on various different methods is not easy. The importance of the issue is enhanced by the potential need for antibiotic treatment.]
