[Examination of leukocyte-endothel interactions in inflammatory animal models]

GONDA Andrea, MIKECZ Katalin, HUNYADI János

[Leukocyte influx into tissues is one of the hallmarks of physiological reactions to inflammatory stimuli, which is followed by a multistep process, resulting in leukocyte extravasation from the postcapillary venules. The different kinds of adhesion molecules, that play role in the rolling and firm adhesion of the leukocytes, have been investigated very intensively. By the help of animal models of inflammation, numerous individuals, being in the same stage of the disease, can be examined. The requirement for the adhesion molecules for inflammatory responses could be investigated with antibodies or, nowadays more often, gene knock out (KO) or transgenic mice. Beside evaluating the morphological and cytokine profile differences, using intravital microscopy is of great importance in the inflammatory experiments, while it allows observing interactions of virtually any blood cell types with the endothelial wall in vivo. The results are sometimes conflicting, indicating that the process of leukocyte-endothel interactions depends on different kind of other factors than the adhesion molecules, and still not fully understood.]

[Alpha calcidol treatment in patients with psoriatic arthropathy: clinical and immunological effects]

GAÁL János, LAKOS Gabriella, ALEKSZA Magdolna, KISS Judit, HORVÁTH Irén, HORKAY Edit, NAGY Georgina, SZEGEDI Andrea

[OBJECTIVE - Our objective was to describe the functional changes of the immune system also to evaluate the clinical parameters during systemic alphacalcidol (1αOH vitamin D3) treatment in patients with psoriatic arthropathy. PATIENTS AND METHOD - Nineteen patients with peripheral polyarticular form of psoriatic arthropathy were investigated. Ten patients were treated with daily 2×25 mcg alphacalcidol per os for 6 months and the other 9 patients served as controls. Three visits (at start, 3 and 6 months later) were carried out during the study, changes in the laboratory and clinical parameters were examined and analysed statistically in the treated and control groups. RESULTS - In the peripheral blood of the treated group a statistically significant decrease in the percentage of CD3/CD69 positive activated and CD8 positive IFNγ producing T cells was observed and the serum level of IFNγ also showed a significant decrease during the first 3 months. Another three months later no change in the above mentioned variables could be detected. Additionally, there was a significant decrease in the clinical activity of the disease using DAS28 score during the whole 6 months follow up period. In the control group no significant changes were observed. CONCLUSION - Our results show that systemic alphacalcidol treatment has a notable immune modulatory effect on patients with psoriatic arthropathy. This effect is manifested in short-term temporary decrease of type 1 immune responses and continuous decrease in the disease activity.]

[The role of endothelial cells]

CERVENAK László

[The role of endothelial cells is much beyond the well known barrier function between blood and tissues. Several different stimuli converge in the endothelial cells, which in turn regulate a number of vital processes in the organisms. Among these processes one of the most important is the immune response. Endothelial cells modulate the homing of leukocytes by the production of adhesion molecules and cytokines depending on activation state, anatomic location and vessel type. Endothelial cells express MHC and costimulatory molecules, which enables them to present antigens to T cells. Antigen presentation may lead to activation or tolerance of T cells depending on the phenotype of endothelial cells. They also express complement regulatory molecules and produce several complement cascade proteins. Endothelial cells take part in the catabolism of immunoglobulins as well as in the removal of circulating immune complexes. Finally, endothelial cells regulate inflammation at different levels by several mechanisms, which may substantially determinate the progression of the immune response.]

[Prevalence of isolated systolic hypertension in our country]

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

[Prevalence of hypertension over the age of 56 is increasing in size and a significant proportion (60-80%) of isolated systolic hypertension. Within the population screening in the older age groups - in the light of economic development - 25-40% of the prevalence. We have an opportunity to analyse the prevalence and specificity of isolated systolic hypertension from age 36 to age 10 years on the base of 7 years data of the MÁESZ (Comprehensive Health Protection Screening Program of Hungary 2010- 2020) survey. Between 56-65 years 23.27-24.23% (male/female) 66-75 years 34,89-33,15% and over 76 years 44.04-41.5% occurrence was found. Divergence of systolic and diastolic pressure has begun since 36 years. Pulse pressure was used to separate individuals with varying degree of vascular disorders.]

[Results of the comprehensive health screening of Hungary (MÁESZ) in 2017 and comparative results of 2010-2017 specially to hypertension]

BARNA István, KÉKES Ede, DAIKI Tenno, DANKOVICS Gergely, KISS István, A MÁESZ Programbizottsága nevében

[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.]

[Is it necessary? - Opinions and experiences about a first aid programme for children - pilot study]

BÁNFAI Bálint, PANDUR Attila, SCHISZLER Bence, RADNAI Balázs, BÁNFAI-CSONKA Henrietta, BETLEHEM József

[INTRODUCTION - Starting first aid education in early childhood can be an effective method of knowledge transfer. AIM - Our aim was to examine first aid education related opinions of kindergarten- and primary school children, educators, and parents. MATERIALS AND METHODS - 871 people (children, educators, parents) were involved in our study. Opinions were measured with self-administered questionnaires, containing mainly open questions. RESULTS - General opinion of parents and educators on first aid education in childhood were mainly positive, but they also gave negative ones. The majority of participants had a positive opinion about our completed program. Based on the opinions of parents and educators first aid education is recommended by health care professionals. Opinions were independent from gender, age, lenght of time of working with children in all cases (p>0.05). CONCLUSIONS - General opinion of parents and educators was varied, but it was generally positive concerning our program. Based on this results opinions can be changed with concrete activities. ]
