[Elderly patients with end-stage renal disease, its epidemiology and questions regarding it in Hungary]

SZEGEDI János, KISS István

[The number of elderly people and the kidney disease’s importance connected to it has increased worldwide, therefore the chronic kidney disease became an endemic. Parallel to the dwindling of population the people in it age. Because of the men’s higher mortality rate the proportion of women in the elderly is greater. Prognosis indicates that by 2060 every third citizen will be aged 65 or more. Between 1990 and 2015 the life expectancy at birth increased by 6.95 years in the case of men (in 1990 it was 61.13, and in 2015 it was 72.08) and by 4.9 years in the case of women (in 1990 it was 73.7, and in 2015 it was 78.6) in Hungary. Chronic kidney disease concerns 10 to 14 % of the population and 1% of all of them suffers from end stage kidney failure. In the end of 2015 3.52 million patients received kidney replacement therapy around the globe (2.42 million received hemodialysis, 329000 received peritoneal dialysis and 704 000 lived with transplanted kidneys). Of all the risk factors of chronic kidney disease age, hypertension, diabetes mellitus and obesity stand out as the most important ones. The kidneys’ anatomy and function change in elderly age, making it possible for the kidney disease to manifest in greater numbers. The elderly dialysis patients’ number increases worldwide which is connected to their higher life expectancy and better life prospects which on the other hand ultimately means that more and more patient lives to suffer from kidney disease. It cannot be disregarded either that the increasing number of elderly patients suffering from hypertension or diabetes means that because these are causes of kidney disease, the latter’s numbers are also increasing. International data indicates that in the case of incident ESRD patients their number was between 68-2784 and the older than 75 years was 142-1660 per million population. In Hungary there was 778/pmp and 677/pmp, respectively. In 2015 the ratio of incident dialysis patients the ones aged above 65 was 58,9% in the case of incident patients and 50,3% in the case of prevalent patients. The ratio of the ones aged above 75 was 28,2% in the case of incident patients and 22,6% in the case of prevalent patients. The number of elderly dialysis patients differs by region too. Dialysis treatment started in elderly age requires special knowledge and teamwork, similarly to the question of refusing the treatment. The latter team work, adequate experts (doctors and nurses) and the related professions’ representatives build the foundations of a proper clinical practice.]

[First experiences with percutaneous renal denervation in management of resistant hypertension]

SCHULCZ Domonkos, NAGY Ferenc Tamás, THURY Attila, BAJCSI Dóra, FEJES Imola, LETOHA Annamária, CONSTANTINOU Kypros, UNGI Imre, ÁBRAHÁM György, LÉGRÁDY Péter

[Percutaneous transluminal radiofrequency renal denervation is a promising new therapeutic method for the treatment of primary resistant hypertension. The intervention decreases the systemic sympathetic over activation and thus arterial blood pressure. In the 1st Department of Medicine of the University of Szeged, 9 resistant hypertensive patients (2 male, 7 female; mean age: 55.0±4.0 years) had all the conditions were required for renal denervation at the time of interventions were performed. We measured the blood pressure together with the heart rate of the patients on the day preceding the intervention, right after the intervention, at discharge from hospital, then at months 6, 9 and 15. The mean blood pressure was 178/107±7/5 mmHg before the intervention. After denervation mean blood pressure decreased right after the intervention, at discharge from hospital, as well as at months 6, 9 and 15, respectively -15/-17 mmHg; -36/-16 mmHg; -19/-9 mmHg; -27/-21 mmHg and -15/- 16 mmHg. Besides decreasing of blood pressure, the antihypertensive drug therapy also decreased, however, it was not the primary aim of the intervention. No denervation- related intra- or perivascular complications were detected. The findings of our study proved the efficacy and safety of renal denervation in the treatment of primary resistant hypertension, of course with an appropriate patient selection. Our study was not relevant to determine whether this method is accompanied with a significant decrease of cardiovascular morbidity and mortality. Answers may come only based on randomized sham controlled studies with great case numbers.]

[Efficacy of a fixed-dose association of amlodipine and lisinopril in grade II and III hypertensive patients]

JOÃO Maldonado, TEIMO Pereira, MARGARIDA Carvalho

[We conducted an observational study, with ambulatory blood pressure monitoring (ABPM), to evaluate the efficacy of a fixed-dose combination of Amlodipine (5 mg) and Lisinopril (20 mg) in grade II and III hypertensive patients, over an 8 week intervention period. Thirty non-medicated hypertensive patients were enrolled, 36% female, with a mean age of 52.44±11.54 years, a body mass index of 28.73±4.54 kg/m2, and brachial office systolic (SBP) and diastolic (DBP) blood pressure of 174.43±15.06 mmHg and 102.83±10.67 mmHg, respectively. All patients performed a 24 hours ABPM at baseline and after a treatment period of 8 weeks with the fixed-dose association. Brachial office blood pressure and routine blood and urine samples were also obtained in both moments. A significant reduction in blood pressure was observed after the treatment with the fixed-dose association. The proportion of patients with controlled ambulatory blood pressure after the treatment was 69%, considering the normalization of the systolic and diastolic ambulatory pressures over the daytime, nighttime and 24 hours. Considering the brachial office blood pressures, the proportion of controlled hypertensive patients reached 79%. A significant improvement was also seen in microalbuminuria (reduction of 37.40 mg/24h; IC: 2.82-71.97; p=0.035) and fasting glycaemia (reduction of 11.53 mg/dl; IC: 3.46-19.61; p=0.007). No side effects were reported during the 8 week treatment period. The treatment of grade II and III hypertensive patients with a fixed-dose association of Amlodipine (5 mg) and Lisinopril (20 mg) during 8 weeks is effective controlling blood pressure. Furthermore, evidences indicate that the efficacy of the association is achieved quickly, safely and with good tolerability.]

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]


[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 ]


[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 ]


[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. ]
