[Blood pressures of adolescents at screening program in Budapest]

KORMOS-TASI Judit, GÁCSI Erika, SCHEURING Noémi, TÓTH Fanni, CZINNER Antal, SZABÓ László

[The Aim of the screening program was to investigate the blood pressure and the association with obesity, hypercholesterinaemia and increased body fluid in adolescents. Methods: A screening program was conducted during the period from April 2010 to May 2011.The screenings consisted of: blood pressure, heart rate, body composition determination, cholesterol, blood glucose, weight, height and BMI. Results: 2226 children fullfied all of the outlined criteria. Their range of age was between 14–18 years. The average systolic blood pressure was 126.34±12.55 Hgmm volt. At boys were higher 131.87±13.59 then at girls 117.49±5.69 Hgmm. The average diastolic blood pressure was 71.86±8.74 Hgmm. There were also higher at boys 72.61±9.17 then at girls 66.69±5.04 Hgmm. High systolic blood pressure (95%<) were 307/1326 cases at girls, and 403/876 cases at boys. High diastolic blood pressure were together with high systolic blood pressure, but less frequency. High diastolic blood pressure occurred at 85 girls and at 90 boys. Overweight and obes were 18.994% of girls and 15.26% of boys. The percentage of pathological high blood pressure was most frequent among boys and girls who are in the overweight group. The pathologically high level of body fat percentage appeared to be 12.98% among girls and 5.9% among boys. In elevated BMI groups the frequency of high body fat was 66% among girls and 81% among boys. The mean cholesterol was significantly higher in the overweight and obese group. Conclusions: Rates of hypertension and overweight and obesity are high in school children in Budapest, and increased bodyweight is a significant risk factor for hypertension. The results of the study will help to design preventive programmers.]

[Plasma ortho-tyrosine/para-tyrosine ratio predicts hyporesponsiveness to erythropoiesis-stimulating agents in dialyzed patients]

KUN Szilárd, MIKOLÁS Esztella, MOLNÁR Gergő Attila, SÉLLEY Eszter, LACZY Boglárka, CSIKY Botond, KOVÁCS Tibor, WITTMANN István

[Objectives: Patients suffering from end-stage renal failure (ESRF) are mostly treated with erythropoiesis-stimulating agents (ESAs). They often show hyporesponsiveness to ESA, which condition is associated with elevated production of free radicals. Phenylalnine (Phe) is converted into para- and ortho-tyrosine (p- and o- Tyr) by hydroxyl free radical. o-Tyr is produced exclusively in this way. However, physiological isomer p-Tyr is formed in significantly higher amounts by phenylalaninehydroxylase, mainly in the kidney. It has been shown that p-Tyr production is decreased in ESRF. As a result, p-Tyr can be replaced by o-Tyr in proteins, e.g. in proteins playing part in signal transduction of erythropoietin. We aimed to study the association of different Tyr isoforms with ESA-responsiveness. Methods: Four groups of volunteers were involved in our cross-sectional study: healthy volunteers (CONTR; n=16), patients on hemodialysis without ESA-treatment (non-ESA-HD; n=8), hemodialyzed patients with ESA-treatment (ESA-HD; n=40) and patients on continuous peritoneal dialysis (CAPD; n=21). Plasma p-, o-Tyr and Phe levels were detected using a high performance liquid chromatography (HPLC)-method, with fluorescence detection. ESA-demand was expressed as ESA-dose, ESAdose/ body weight and erythropoietin resistance index1 (ERI1, weekly ESA-dose/body weight/hemoglobin). Multivariate regression models were used to examine predictors of ESA-demand. In these models, most of the known predictors of ESA-hyporesponsiveness were included. Results: Lower p-Tyr levels were found in dialyzed patients compared with control subjects. In contrast, o-Tyr levels and o-Tyr/p-Tyr ratios were higher in dialyzed patients. Regarding dialyzed patients, o-Tyr level and o-Tyr/p-Tyr ratio were higher in ESA-HD than in non-ESA-HD and CAPD groups. Weekly ESA-dose/body weight and ERI1 correlated with o-Tyr/p-Tyr ratio (r=0.441, p=0.001; r=0.434, p=0.001, respectively). Finally, o-Tyr/p-Tyr ratio proved to be an independent predictor of ERI1 (β=0.330, p=0.016). Discussion: Our results suggest that elevation of o-Tyr/p-Tyr ratio could be responsible for ESA-hyporesponsiveness in dialyzed patients.]

[Initiation of antihipertensive therapy with fix combinations, focusing on perindopril, amlodipine and indapamide]

FARSANG Csaba

[Early clinical studies proved that most hypertensive patients (>70%) need drug combinations to reach the target blood pressure. We should combine two or three - sometimes more - drugs from different antihypertensive classes for quicker normalisation of blood pressure and to reduce incidence and severity of hypertensive complications. Several international and Hungarian (MHT 2015) guidelines emphasize the advantages of fix combinations against free combinations. Most frequently used combinations contain ACEi + calcium antagonist, or ACEi + diuretic. From them I will focus on the perindopril + amlodipine or perindopril + indapamide combinations. If we do not reach target blood pressure, triple fix combinations (e.g. perindopril + amlodipine + indapamide) can also be used. Now there are fix combinations of different strengths, therefore we may start the therapy with these fix combinations according to patients’ characteristics (e.g. age, complications, concomitant diseases).]

[Rilmenidin - a versatile combination partner in the treatment of high blood pressure]

KÉKES Ede

[The rilmenidin as an imidazoline agonist drug strongly decreases the central sympathetic activity, release of renine and the RAS activity. Because of these advantageous properties the peripheral vascular resistance falls and the blood pressure is decreased. Today it is excellent tool for combination therapy. Useful especially in stress induced hypertension. The antihypertensive effects of ACE inhibitors sor calcium antagonists are increased by rilmenidine. This drug decreases the insuline resistance, it has a positive effect on the carbohydrate and fat metabolism, because it is useful as a complementary therapy in metabolic syndrome and diabetes mellitus of type II. It is useful in stress induced hypertension, and in menopause as well.]

Cholinesterase inhibitors and memantine for the treatment of Alzheimer and non-Alzheimer dementias

BALÁZS Nóra , BERECZKI Dániel, KOVÁCS Tibor

In aging societies, the morbidity and mortality of dementia is increasing at a significant rate, thereby imposing burden on healthcare, economy and the society as well. Patients’ and caregivers’ quality of life and life expectancy are greatly determined by the early diagnosis and the initiation of available symptomatic treatments. Cholinesterase inhibitors and memantine have been the cornerstones of Alzheimer’s therapy for approximately two decades and over the years, more and more experience has been gained on their use in non-Alzheimer’s dementias too. The aim of our work was to provide a comprehensive summary about the use of cholinesterase inhibitors and memantine for the treatment of Alzheimer’s and non-Alzheimers’s dementias.

BOCZÁN Judit, KLIVÉNYI Péter, KÁLMÁN Bernadette, SZÉLL Márta, KARCAGI Veronika, ZÁDORI Dénes, MOLNÁR Mária Judit

[Background – Spinal muscular atrophy (SMA) is an autosomal recessive, progressive neuromuscular disorder resulting in a loss of lower motoneurons. Recently, new disease-modifying treatments (two drugs for splicing modification of SMN2 and one for SMN1 gene replacement) have become available. Purpose – The new drugs change the progression of SMA with neonatal and childhood onset. Increasing amount of data are available about the effects of these drugs in adult patients with SMA. In this article, we summarize the available data of new SMA therapies in adult patients. Methods – Members of the Executive Committee of the Hungarian Clinical Neurogenetic Society surveyed the literature for palliative treatments, randomized controlled trials, and retrospective and prospective studies using disease modifying therapies in adult patients with SMA. Patients – We evaluated the outcomes of studies focused on treatments of adult patients mainly with SMA II and III. In this paper, we present our consensus statement in nine points covering palliative care, technical, medical and safety considerations, patient selection, and long-term monitoring of adult patients with SMA. This consensus statement aims to support the most efficient management of adult patients with SMA, and provides information about treatment efficacy and safety to be considered during personalized therapy. It also highlights open questions needed to be answered in future. Using this recommendation in clinical practice can result in optimization of therapy.]

DEMIR Fıgen Ulku, BOZKURT Oya

Aim - The aim of this study was to evaluate the frequency and characteristics of attacks in patients with migraine, to determine the effects of anxiety or depressive symptoms, and to evaluate the marital relationships of patients with migraine. Method - Thirty patients who were admitted to the neurology outpatient clinic of our hospital between July 2018 and October 2018 and were diagnosed with migraine according to the 2013 International Headache Society (IHS) diagnostic criteria were included in this cross-sectional study. Age, sex, headache frequency and severity, depressive traits, marital satisfaction and anxiety status were examined. We used the Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), Maudsley Marital Questionnaire (MMQ) and Visual Analogue Scale (VAS) for measuring relevant parameters. Results - The mean severity of migraine pain according to VAS scale was 6.93 ± 1.41 and the mean number of migraine attacks was 4.50 ± 4.24. The mean BDI score of the patients was 12.66 ± 8.98, the mean MMQ-M score was 19.80 ± 12.52, the mean MMQ-S score was 13.20 ± 9.53, the mean STAI-state score was 39.93 ± 10.87 and the mean STAI-trait score was 45.73 ± 8.96. No significant correlation was found between age, number of migraine attacks, migraine duration, migraine headache intensity, and BDI, STAI and MMQ scores (p>0.05). But there was a positive correlation between MMQ-S and scores obtained from the BDI and STAI-state scales (p<0.05). Conclusion - In this study more than half of the migraine patients had mild, moderate or severe depression. A positive correlation was found between sexual dissatisfaction and scale scores of depression and anxiety.

[Cardiovascular prevention 2021 – Guidelines of European Society of Cardiology 2021. General principles]

VÁLYI Péter, KÉKES Ede

[On 31 August 2021, the European Society of Cardiology published its guideline “Prevention of cardiovascular disease in clinical practice”. This guideline provides a comprehensive review about risk factors of atherosclerotic cardiovascular disease, their assessment, potential modifiers, treatment and prevention of the cardiovascular disease itself at societal and individual levels respectively. The previous guideline issued 2016, had to be updated due to the recent significant advances in risk prediction of cardiovascular disease on atherosclerotic background and due to the beneficial effects of treatment, emerging new drugs and therapeutic targets. The risk assessment system has undergone a major overhaul and now predicts the risk of fatal and non-fatal cardiovascular events together over a 10-year horizon and over a lifetime. In the new guideline, age plays a more important role in risk classification than before. The risk assessment and staged management of apparently healthy people or patients with established atherosclerotic cardiovascular disease, diabetes mellitus and other specific diseases or conditions are detailed. The positive impact of influencing risk factors, the years of life gained can recently be presented in a lifetime perspective, which will help to make an individually tailored decision on the extent of interventions, taking into account also the patient'’s preferences.]

[May measurement month: analysis of the Hungarian results of years 2017 and 2019]

NEMCSIK János, PÁLL Dénes, JÁRAI Zoltán

[Cardiovascular (CV) diseases are not only the leading causes of mortality in Hungary, but also the mortality rate is excessively high compared with the average of European Union, so screening programs identifying subjects with elevated blood pressure (BP) is of utmost importance. May Measurement Month (MMM) is an annual global initiative which began in 2017 aimed at raising awareness of high BP. Hungary, through the Hungarian Society of Hypertension has joined the campaign of MMM from the beginning. The results of years 2017 and 2019 are presented in this paper. ]
