[The regulation of the homeostasis of sodium and water is one of the oldest fields in medical research. Our article exhibits a new aspect of sodium balance: the concept of the regulated sodium storage taking place in the interstitium of the skin. We summarize the history of the research carried out in this area, beginning with the discovery of osmotically inactive sodium reservoirs to the localization of these buffers and the elucidation of the role of a regulating cutaneous cascade, which has an effect on blood pressure. Glycosaminoglycan (GAG) macromolecules present in the skin interstitium, come into reversible contact with the excess of dietary sodium intake. Thus in addition to the known role of the kidney, the above system may contribute to the regulation of sodium- and water balance and thereby to the regulation of blood pressure.]

[Hemodynamic approach of the treatment of hypertension. The possible role of impedance cardiography in the tailored antihypertensive therapy]


[It is important to achieve the blood pressure targets in the course of antihipertensive therapy. It will be beneficial to increase the proportion of patients on blood pressure target to avoid adverse cardiovascular consequences. In hypertension the main definition the elevation of blood pressure alone, but in hypertension are several abnormalities of cardiac output, systemic vascular resistance, stroke volume and arterial compliance too. Impedance cardiography is a simple highly accurate non-invasive device to assess hemodynamic parameters in hypertension. Hemodynamic assessment may help in the treatment of hypertension. Various authors report the improving rate of blood control rate using impedance cardiography which may decrease the risk of target organ damage.]

[Dialysis treatment in Hungary: 2010–2015]


[The authors show the data of Hungarian dialysis statistics from 2010 to 2015. The questionnaire - based data collection was made by Dialysis Registry Committee of the Hungarian Society of Nephrology. The number of all patients entered in the dialysis program increased by 8.4% over six years (an average of 1.4/ per year) and the number of new ones increased by 10.5% (1.75% per year). Between 2003 and 2009 the mean annual increasing of new patients was 7.5%! The incidence of new dialyzed patients was 440/1 million population in 2010 and 486/1 million) in 2015. The population point prevalence at the end of the year was 621/1 million in 2010 and 643/1 million in 2015. The penetrance of peritoneal dialysis was 13.5% in 2010, and 13.6% in 2015. The proportion of incident patients with diabetic or hypertensive nephropathies (conditions which lead to end stage renal disease) was about the same in 2010 (27 and 21%) than in 2016 (27 and 22%). The mean age of incident patients entered into dialysis program decreased from 66.9 years (2010) to 62.8 years (2015), surprisingly. The rate of patients on waiting list for renal transplantation was 10.7% in 2009 and increased to 15,8% in 2015. There is also a significant increase in the number of the annual renal transplantations (268 in 2010 and 356 in 2015). The mortality rate of chronically dialyzed patients shows little decrease (14.4-13.1%).]

[The effect of nonsteroidal anti-inflammatory drugs on articular cartilage]

GÁTI Tamás, JUHÁSZ István, ROJKOVICH Bernadette

[In developed countries, the treatment of osteoarthritis costs up to 1-2% of the GNP. The poor hygroscopy of hyaline cartilage and of glycosaminoglycan (GAG) molecules that are components of proteoglycans plays a key role in the development of the disease. Age-related osteoarthritis mostly affects the weight-bearing joints of the lower extremities, the hips and knees, and - more frequently than the former ones - the small joints of the hands, causing chronic pain and disability. Nonsteroidal anti-inflammatory drugs (NSAIDs) used for the treatment of osteoarthritis-related pain influence not only pain but also cartilage metabolism, and - among others - GAG molecules. NSAIDs diminish the biosynthesis of prostaglandins (PG) that have a role in inflammatory processes, and influence oxygen free radicals, the levels of interleukins (ILs) and the function of metalloproteinases. The ideal NSAID for the joints stimulates cartilage formation, reduces cartilage resorption, and the level of katabolic cytokines. Aceclofenac was found to have the most beneficial effect on multiple aspects of cartilage metabolism.]

[Population based study of hypertension in Hungary - 2012 Comprehensive Health Protection Screening Program of Hungary 201-2020]

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

[Background: The year 2011 saw the continuation of Hungary’s greatest and to date most comprehensive health screening programme started in 2010. The aim of the screening programme established according to the directives of the European Union with the cooperation of more than forty professional organisations is the preservation of the health of the population, the prevention of illnesses and the improvement of the general health status. The programme contributes to the prevention of coronary diseases by passing on knowledge concerning healthy nutrition and guidelines to help the establishment of a health-conscious lifestyle. Partecipants and methods: In the Comprehensive Health Tests Programme of Hungary, the examinations, among them coronary examinations covering the fields of cardiology and hypertension, take place in a specially furnished lorry. The results of the examinations of the people who have presented themselves for the tests (n=19,814) have been evaluated. In the Comprehensive Health Tests Programme of Hungary a total of 10,444 (52.7%) women and 9,370 (47.3%) men were tested at 332 locations. Although the tests were free for all adults, predominantly persons between the ages of 26 and 55 presented themselves. The average age of women was 42 years and that of the men was 40 years. Results: Upon data processing with the help of a query, 28% of the participants reported suffering from hypertension disease. Measurement of the blood pressure was carried out in each case with validated equipment and by qualified medical staff. Based on the data, it can be observed that while among men hypertension tends to occur in larger numbers at a younger age, the tendency is reversed at ages above 45 years, where hypertension is more frequent among women. Among women, the state of normotonia was most frequent up to the age of 45 and stage 1 hypertension became most frequent from the age of 46 onwards. It must be noted, however, that stage 3 hypertension was already present in 1.7% of women of 26 years of age, and the frequency of this category increased to 6% from the age of 46 onwards. The average systolic blood pressure measured among men exceeded the upper limit of the normal range for all age groups. The average systolic blood pressure measured among women was in the normal range up to the age of 55 years and only moved to the pathological range from the age of 56 onwards. The diastolic blood pressure levels were in the normal range for both sexes (with the exception of the age group 46-55 of the men, where it exceeded the upper limit of the normal range by a minimal extent). Among the men, stage 1 hypertension was the most frequent status for all age groups; blood pressures above 140/90 were measured for 39% of the subjects from the age of 18 onwards. The distribution of this did not vary significantly with the increase of age. It must be mentioned here too, that stage 3 hypertension became more frequent with age, and that it was observed in more than 11% of the patients above 56 years of age. The correlation between abdominal circumference, total cholesterol, blood sugar level and the measured blood pressure values was unambiguously ascertainable. In case of simultaneous presence of diabetes and hypertension (women, n=344 and men, n=303), blood pressures above 140/90Hgmm were 2-3 times more frequent for both sexes than without the presence of diabetes. Discussion: Thanks to the vast information obtained through the programme, a comprehensive picture has been drawn up about Hungary’s present health status not only on a regional or cross sectional level, but as it was described in the programme, too. ]

[Similarities and differences of the most significant international guidelines for the treatment of hypertension]


[Guidelines of diagnosing and treating hypertension play pre-eminent role in maintaining health in our World. Based on reliable estimates we have to take in ac­count more than 1.6 billion individuals suffering from hypertension by 2025. Ad­he­rence to the guidelines is a vital issue for all high blood pressure patients, however, also the economically developed countries have a disappointing share of well-controlled hypertension. Unfortunately, on the 5 continents of the world, the guidelines provide different or very different recommendations for measuring blood pressure, making diagnosis, estimating cardiovascular risk, and setting a target value, although an attempt has been made in the recent years for developing “consensus” in specific issues. This study presents the different opinions and resolutions by analysing the ACC/AHA, ESC/ESH, NICE, Canadian and Australian guidelines. WHO and ISH resolutions were also concerned. We describe the mutual ad­justment in theoretical and practical terms of the guidelines and the consensus that have already been estab­lished.]

[Cannabinoid research in the last two decades became one of the most important fields in medical science, mainly because of the discovery of the endocannabinoid system and the understanding of the close connections between this system and several important diseases and pathological states. The endocannabinoid system has been shown to be present and active in many tissues and organs including the central nervous, gastrointestinal and reproductive systems, liver, lungs and bones. Its role in eye function, malignant diseases, pain and inflammation has also been studied. This review gives a summary of all these results with special attention to the role of the endocannabinoid system in energy metabolism and cardiovascular regulation.]
