[Role of activated cells and local inflammatory mechanisms in the development of hypertension]

LELBACH Ádám, KOLLER Ákos

[In the past decades an increasing attention has been paid regarding the possible role of the immune system in the development of hypertension. In vitro and in vivo animal experiments, as well as human studies provided evidence for the role of the innate and adaptive immune systems in the development of hypertension, especially in connection with the perivascular adipose tissue, heart and kidney. Inflammatory mediators, cytokines, reactive oxygen metabolites have not only local pro-hypertensive effecting the vasculature, but also influence the development of hypertension through other regulatory mechanisms, such as the central nervous system. These findings provide a new understanding of the development of hypertension, as well as offer new potential mechanisms that can be targeted with novel the - rapies.]

[The importance of the increase in the use of fix dosage combination of calcium channel blockers in the domestic medical practice between 2007 and 2013]

BARNA István, GYURCSÁNYI András

[Antihipertensive therapy in the complex treatment of diabetes mellitus, obesity and lipid metabolism disorder was discussed, which also means the fight against the emergence of cardiometabolic syndrome and chronic renal failure as well. Angiotensin converting enzyme (ACE) inhibitors, angiotensin receptor antagonists (ARBs), calcium channel blockers (CCB), b-blockers and thiazid diuretics with “A” level of evidence reduce cardiovascular morbidity and mortality. The main effect of CCBs is effective antihipertensive vasodilatation, which is the basis of anti-ischaemic, anti-anginal and antihipertensive agents for use in everyday practice. Based on the database of the National Health Insurance, we analyzed changes in the turnover of CCBs between 2007 and 2013 the examined period among CCBs ordered with TB support amlodipin is the most frequently used active ingredient. In December 2007 almost 75% of the prescriptions was amlodipin. That increased to 87,12% by December 2013. CCBs ordered in monotherapy not changed in the examined period, while combinations increased continuously Among CCBs between 2007 and 2013 the fix dosage combinations available with TB support are: statins (atorvastatin + amlodipin), ACE inhibitors (ramipril + felodipin, lisinopril + amlodipin, perindopril + amlodipin, ramipril + amlodipin, verapamil + trandolapril) and b-blockers (metoprolol + felodipin). Using the assigned CCB monotherapy decreased steadily during the study period, while the use of combination formulations induced gradually increased. At the end of the examined seven year period more than 40% of the prescribed boxes were CCB in fix combination. Use of the combination of amlodipin + perindopril increased while amlodipin + lisinopril continuously reduced. The use of the combination of felodipin + ramipril also decreased.]

[Monitoring of effectiveness of ramipril-amlodipine fixed combination in metabolic syndrome, a non-interventional trial (The RAMSES Study)]

TOMCSÁNYI János, SIMONYI Gábor

[Hypertension is a cardiovascular risk factor. The 6th Cardiovascular Consensus Conference has recommended metabolic syndrome in high-risk category. In diabetic patients hypertension is observed in most cases. Aims: Monitoring the effectiveness and safety of the fix combination of ra - mipril/amlodipine therapy in patients with metabolic syndrome suffering from mild or moderate hypertension despite current antihypertensive treatment. Patients and methods: Open, prospective, phase IV clinical observational study, which involved known metabolic syndrome patients (age over 18 years) with mild or mode - rate hypertension. Ramipril/amlodipine fixed combination (5/5, 5/10, 10/5 or, 10/10 mg) were administered or titrated in 3 visits, during the 6 months of trial period. The doses of the fixed combination drugs were determined individually during the visits by physicians involved in the study. The target blood pressure value was 140/90 mmHg and <140/85 mmHg in diabetic patients. Results: 63% of total patient (9,052) have fulfilled the protocol during the four month of trial (5,707 patients). The age of patients was 61.3±11.97 (mean±SD) years, 2.736 (47.9%) men and 2,971 (52.1%) women. 74.0% of total metabolic patients has reached target blood pressure at the end of 6th month (primary end point). The blood pressure has decreased significantly from 158.7±8.97/91.9±7.30 mmHg (1. visit) to 131.6±7.73/79.8±12.20 mmHg (-27.1±10.43 /12.1±13.38 mmHg) to the 6th month (3. visit) (p<0.0001). Patients with hypertension in metabolic syndrome have tolerated the various fixed combination of ramipril/amlodipine well. ]

[Effects of peripheral resistance lowering and elevating beta-blockers on central blood pressure - nebivolol in focus]

BENCZÚR Béla

[Central blood pressure, that is, blood pressure (BP) in the ascending aorta, is considered an important physiologic parameter as it reflects the hemodynamic relationship between the heart and the aorta, both in systole and in diastole. In the systolic phase, central BP represents the pressure against which the left ventricle has to eject blood during systolic contraction. Thus, central arterial pressure reflects both left ventricular stroke volume and afterload, defines cardiac work, and contributes to the development of left ventricular hypertrophy in hypertensive individuals. In the diastolic phase, central BP is a key determinant of the blood flow delivery to the myocardium. Despite the increasing knowledge regarding the importance of central blood pressure and the availability of non-invasive measurement technics it couldn’t spread in everyday clinical practice and rarely or not mentioned in the therapeutic guidelines. The different antihypertensiv drugs significantly differs based on their effects on central blood pressure particularly β-blockers. The so-called ’classical’ β-blockers have un - favourable effect on central blood pressure due to increasing peripherial vascular resistance. In the opposit the vasodilating β-blockers including nebivolol markedly decrease central blood pressure which could explain their beneficial effects.]

Cases of inborn errors of metabolism diagnosed in children with autism

CAKAR Emel Nafiye, YILMAZBAS Pınar

Autism spectrum disorder is a neurodevelopmental disorder with a heterogeneous presentation, the etiology of which is not clearly elucidated. In recent years, comorbidity has become more evident with the increase in the frequency of autism and diagnostic possibilities of inborn errors of metabolism. One hundred and seventy-nine patients with diagnosis of autism spectrum disorder who presented to the Pediatric Metabolism outpatient clinic between 01/September/2018-29/February/2020 constituted the study population. The personal information, routine and specific metabolic tests of the patients were analyzed retrospectively. Out of the 3261 patients who presented to our outpatient clinic, 179 (5.48%) were diagnosed with autism spectrum disorder and were included in the study. As a result of specific metabolic examinations performed, 6 (3.3%) patients were diagnosed with inborn errors of metabolism. Two of our patients were diagnosed with classical phenylketonuria, two with classical homocystinuria, one with mucopolysaccharidosis type 3D (Sanfilippo syndrome) and one with 3-methylchrotonyl Co-A carboxylase deficiency. Inborn errors of metabolism may rarely present with autism spectrum disorder symptoms. Careful evaluation of the history, physical examination and additional findings in patients diagnosed with autism spectrum disorder will guide the clinician in the decision-making process and chose the appropriate specific metabolic investigation. An underlying inborn errors of metabolism may be a treatable cause of autism.

[The connection between the socioeconomic status and stroke in Budapest]

VASTAGH Ildikó, SZŐCS Ildikó, OBERFRANK Ferenc, AJTAY András, BERECZKI Dániel

[The well-known gap bet­ween stroke mortality of Eastern and Western Euro­pean countries may reflect the effect of socioeconomic diffe­rences. Such a gap may be present between neighborhoods of different wealth within one city. We set forth to compare age distribution, incidence, case fatality, mortality, and risk factor profile of stroke patients of the poorest (District 8) and wealthiest (District 12) districts of Budapest. We synthesize the results of our former comparative epidemiological investigations focusing on the association of socioeconomic background and features of stroke in two districts of the capital city of Hungary. The “Budapest District 8–12 project” pointed out the younger age of stroke patients of the poorer district, and established that the prevalence of smoking, alcohol-consumption, and untreated hypertension is also higher in District 8. The “Six Years in Two Districts” project involving 4779 patients with a 10-year follow-up revealed higher incidence, case fatality and mortality of stroke in the less wealthy district. The younger patients of the poorer region show higher risk-factor prevalence, die younger and their fatality grows faster during long-term follow-up. The higher prevalence of risk factors and the higher fatality of the younger age groups in the socioeconomically deprived district reflect the higher vulnerability of the population in District 8. The missing link between poverty and stroke outcome seems to be lifestyle risk-factors and lack of adherence to primary preventive efforts. Public health campaigns on stroke prevention should focus on the young generation of socioeconomi­cally deprived neighborhoods. ]

[What happens to vertiginous population after emission from the Emergency Department?]

MAIHOUB Stefani, MOLNÁR András, CSIKÓS András, KANIZSAI Péter, TAMÁS László, SZIRMAI Ágnes

[Background – Dizziness is one of the most frequent complaints when a patient is searching for medical care and resolution. This can be a problematic presentation in the emergency department, both from a diagnostic and a management standpoint. Purpose – The aim of our study is to clarify what happens to patients after leaving the emergency department. Methods – 879 patients were examined at the Semmel­weis University Emergency Department with vertigo and dizziness. We sent a questionnaire to these patients and we had 308 completed papers back (110 male, 198 female patients, mean age 61.8 ± 12.31 SD), which we further analyzed. Results – Based on the emergency department diagnosis we had the following results: central vestibular lesion (n = 71), dizziness or giddiness (n = 64) and BPPV (n = 51) were among the most frequent diagnosis. Clarification of the final post-examination diagnosis took several days (28.8%), and weeks (24.2%). It was also noticed that 24.02% of this population never received a proper diagnosis. Among the population only 80 patients (25.8%) got proper diagnosis of their complaints, which was supported by qualitative statistical analysis (Cohen Kappa test) result (κ = 0.560). Discussion – The correlation between our emergency department diagnosis and final diagnosis given to patients is low, a phenomenon that is also observable in other countries. Therefore, patient follow-up is an important issue, including the importance of neurotology and possibly neurological examination. Conclusion – Emergency diagnosis of vertigo is a great challenge, but despite of difficulties the targeted and quick case history and exact examination can evaluate the central or peripheral cause of the balance disorder. Therefore, to prevent declination of the quality of life the importance of further investigation is high.]

[A short chronicle of three decades ]

KAPRONCZAY Katalin

[Hungarian professional periodicals started quite late in European context. Their publish­ing, editing and editorial philosophy were equally influenced by specific historical and political situations. Certain breaking points of history resulted in termina­tion of professional journals (War of In­de­pendence 1848-1849, First and Se­cond World Wars), however there were pe­riods, which instigated the progress of sciences and founding of new scientific journals. Both trends were apparent in years after the fall of former Hungarian regime in 1990. The structure of book and journal publishing has changed substantially, some publishers fell “victim” others started successfully as well. The latters include the then-established publishing house Literatura Medica and its own scientific journal, Lege Artis Me­di­cinae (according to its subtitle: New Hun­garian Medical Herald) issued first in 1990. Its appearance enhanced significantly the medical press market. Its scientific publications compete with articles of the well-established domestic medical journals however its philosophy set brand-new trends on the market. Concerning the medical community, it takes on its problems and provides a forum for them. These problems are emerging questions in health care, economy and prevention, in close interrelation with system of public health institutions, infrastructure and situation of those providing individual health services. In all of them, Lege Artis Medicinae follows consequently the ideas of traditional social medicine.]

[History of vaccine production in Hungary ]

ÓCSAI Lajos

[This study presents the complete history of the Hungarian vaccine production, partly in association with the process of fighting vaccine-preventable infectious diseases, and underlines the fact that every government actively contributed to the age-adjusted mandatory vaccination schedule of the past 140 years. It demonstrates the various achievements from the smallpox lymph production through the launch of diphtheria serum production at Phylaxia and the establishment of the National Public Health Institute (OKI) with its vaccine production and the later institutional transformation of OKI into Humán as economic corporation to its closure. Among all OKI’s vaccine production activities, this study focuses on the production of influenza vaccines, due to its international importance in the 1960s and 1970s. The vaccine production against diphtheria tetanus and pertussis stands out from Humán’s activities, and the tetanus component of this vaccine is still used in the products of a multinational vaccine manufacturer. ]
