[Role of ketoanalogue amino acids and diet in the treatment of patients with chronic kidney disease]

KISS István, HARIS Ágnes, DEÁK György

[Low protein diet is an important component of the non-pharmacological treatment of patients with chronic kidney disease (CKD). Along with the diet it is important to maintain appropriate energy intake to avoid malnutrition. It is recommended to supplement low protein diet (0.6-0.7 g protein/kg body weight/day) with essential amino acids and their ketoanalogues (ketoacids) in a dose of 1 tablet/8-10 kg body weight if there is a threat of protein malnutrition (eg. vegan diet). Very low protein diet (0.3-0.4 g protein/kg body weight/day) should be supplemented with ketoacids in a dose of 1 tablet/5 kg body weight. Low protein diet is recommended for patients with CKD stage 3 and progressively declining renal function, or nephrotic syndrome; in diabetic nephropathy; in CKD stage 4 and non-dialyzed CKD stage 5. Nephroprotective effect of very low protein diet is primarily expected is patients with an eGFR below 20-25 ml/min/1.73 m2 and good compliance. Dietary protein restriction may diminish acidosis and proteinuria, slow the progression of CKD and delay initiation of dialysis. Diets reduced in protein supplemented with appropriate energy intake and ketoacids are nutritionally safe. Dietary education and guidance of patients by qualified dietitians are of great importance in nephrology clinics. We illustrate the main points of our review with case reports.]

[The year 2017 saw the continuation of Hungary’s greatest and to date most comprehensive health screening program started in 2010. The examinations - among them coronary examinations - covered the fields of cardiology and hypertension, they took place in a specially furnished lorry. In the program we measured blood pressure, pulse rate, calculated cardiovascular risk, plasma cholesterol, glucose and uric acid levels. Whole body analysis started with measuring height, weight, abdominal circumference and waist/hip ratio defining target body weight. Following the measurement of body fat and muscle content we decided the surface volume of the abdominal fat and calculated body mass index. Participants and results of the examinations of the people who have presented themselves for the test since 2017 have been evaluated. In the Program a total (52.2%) women and (47.8%) men were tested at 204 locations. Upon data processing with the help of a query 21.9% of the participants reported suffering from hypertension. The screening truck has been to 1505 places is Hungary, and travelled 183,335 km, 135,879 people have participated in comprehensive screening. The average systolic blood pressure among women was in the normal range up to the age of 55 years. The diastolic blood pressure levels were in the normal range for both sexes (with the exception of the age group 46-55 of men where it exceeded the upper limit of the normal range by a minimal extent). Among men stage 1 hypertension was the most frequent status for all age groups; blood pressures above 140/90 were measured for 39% of subjects from age 18 onwards. Conclusions: Thanks to the vast information obtained through the program a comprehensive picture has been drawn about Hungary’s present health status not only on a regional or cross sectional level but as it was described in the program, too.]

[Telemedicine care for high-risk hypertensive patients with antihypertensive for reaching better blood pressure target ratio and smaller blood pressure variability]

KISS István, ÁDÁM Ágnes, HERCZEG Béla, MATOLTSY András, POÓR Ferenc, SZEGEDI János, VÁRALLYAY Zoltán, PAKSY András, KÉKES Ede

[Telehealth care of high-risk hypertensive patients for a better target blood pressure and smaller size blood pressure fluctuation. Authors conducted a one-year, multicentre, prospective, observational study with no intervention. Their aim was to achieve better targeting and smaller blood pressure fluctuation in patients with high risk hypertensive patients with the new type of doctorpatient co-operation and telemedicinal care than the conventional control method. In the active group, 50 patients, in the non-active group 47 treated hypertensive patients were analysed. During the observation period (1 year) the mean (± SD) of the systolic blood pressure decreased from 143.3 (15.1) mmHg to 134.5 (9.2) mmHg in the active group, but in the non-active group there was no significant decrease. The target blood pressure (< 140/90 mmHg) could be increased from 46% to 62%. The two characteristics of interpersonal visit-to-visit variability index. The standard deviation (SD) and variation coefficient (VC) showed a significant decrease in the active group. There was no change in the inactive group. A method supported by telemedicine-assisted and better patientphysician- assistant co-operation is suitable for increasing target blood pressure rates and reducing blood pressure fluctuation.]

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo – a clinico-pathological case reporT

Although vertigo is one of the most common complaints, intracranial malignant tumors rarely cause sudden asymmetry between the tone of the vestibular peripheries masquerading as a peripheral-like disorder. Here we report a case of simultaneous temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting as acute unilateral vestibular syndrome, due to the reawakening of a primary gastric signet ring cell carcinoma. Purpose – Our objective was to identify those pathophysiological steps that may explain the complex process of tumor reawakening, dissemination. The possible causes of vestibular asymmetry were also traced. A 56-year-old male patient’s interdisciplinary medical data had been retrospectively analyzed. Original clinical and pathological results have been collected and thoroughly reevaluated, then new histological staining and immunohistochemistry methods have been added to the diagnostic pool. During the autopsy the cerebrum and cerebellum was edematous. The apex of the left petrous bone was infiltrated and destructed by a tumor mass of 2x2 cm in size. Histological reexamination of the original gastric resection specimen slides revealed focal submucosal tumorous infiltration with a vascular invasion. By immunohistochemistry mainly single infiltrating tumor cells were observed with Cytokeratin 7 and Vimentin positivity and partial loss of E-cadherin staining. The subsequent histological examination of necropsy tissue specimens confirmed the disseminated, multi-organ microscopic tumorous invasion. Discussion – It has been recently reported that the expression of Vimentin and the loss of E-cadherin is significantly associated with advanced stage, lymph node metastasis, vascular and neural invasion and undifferentiated type with p<0.05 significance. As our patient was middle aged and had no immune-deficiency, the promoting factor of the reawakening of the primary GC malignant disease after a 9-year-long period of dormancy remained undiscovered. The organ-specific tropism explained by the “seed and soil” theory was unexpected, due to rare occurrence of gastric cancer to metastasize in the meninges given that only a minority of these cells would be capable of crossing the blood brain barrier. Patients with past malignancies and new onset of neurological symptoms should alert the physician to central nervous system involvement, and the appropriate, targeted diagnostic and therapeutic work-up should be established immediately. Targeted staining with specific antibodies is recommended. Recent studies on cell lines indicate that metformin strongly inhibits epithelial-mesenchymal transition of gastric cancer cells. Therefore, further studies need to be performed on cases positive for epithelial-mesenchymal transition.

[Diagnosis and treatment of microvascular coronary heart disease. Specialities of conditions in Hungary]

SZAUDER Ipoly

[Invasive investigations show that in two-thirds of patients the myocardial ischaemia persists without obstructive coronary disease and any other heart conditions (INOCA). The underlying cause may be microvascular dysfunction (CMD) with consecutive microvascular coronary disease (MVD) and microvascular or epicardial vasospastic angina (MVA). The modern practice of clinical cardiology while using the developed non-invasive cardiac imaging permits exact measuring of the coronary flow with its characteristic indices. All of these improve the diagnosing of CMD-induced myocardial ischemia and provide opportunity to determine primary MVD cases. Since the recognition and treatment of MVD is significantly underrep­resented in the Hungarian medical care, the primary stable microvascular angina (MVA) is described in detail below with its modern invasive and non-invasive differential diagnosis and treatment, concerning especially its frequency provoked by high blood pressure and female coronary heart diseases. There are highlighted all recommended diagnostic procedures available under domestic conditions.]

[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. ]

[Focus on Lege Artis Medicinae (LAM)]

VASAS Lívia, GEGES József

[Three decades ago, LAM was launched with the goal of providing scientific information about medicine and its frontiers. From the very beginning, LAM has also concerned a special subject area while connecting medicine with the world of art. In the palette of medical articles, it remained a special feature to this day. The analysis of the history of LAM to date was performed using internationally accepted publication guidelines and scientific databases as a pledge of objectivity. We examined the practice of LAM if it meets the main criteria, the professional expectations of our days, when publishing contents of the traditional printed edition and its electronic version. We explored the visibility of articles in the largest bibliographic and scientific metric databases, and reviewed the LAM's place among the Hun­ga­rian professional journals. Our results show that in recent years LAM has gained international reputation des­pite publishing in Hungarian spoken by a few people. This is due to articles with foreign co-authors as well as references to LAM in articles written exclusively by foreign researchers. The journal is of course full readable in the Hungarian bibliographic databases, and its popularity is among the leading ones. The great virtue of the journal is the wide spectrum of the authors' affiliation, with which they cover almost completely the Hungarian health care institutional sys­tem. The special feature of its columns is enhanced by the publication of writings on art, which may increase Hungarian and foreign interest like that of medical articles.]
