Type 1 diabetes mellitus (T1D) is an organ-specific autoimmune disease characterised by autoimmune destruction of insulin-producing beta cells in the islets of Langerhans. It is a long-term process initiated months or even years prior to the clinical onset. The main role in the pathogenesis is played by T lymphocytes but other cell types are involved as well. The presence of autoantibodies in the circulation is typical even before the disease onset. Nowadays, intensive research is focused on finding individuals at risk and developing an effective prevention. During my postgraduate studies I was involved mainly in the research of T1D prediction and prevention. We investigated the relationship of established autoimmune markers - autoantibodies - and the cellular reactivity to GAD65 and IA2 autoantigens. We discovered that the reaction to autoantigens is very individual and it is influenced by the patient's autoantibody profile. These results could be relevant in planning antigen-specific immunointervention studies and improving their efficacy. We also made an attempt to improve specificity and sensitivity of a beta cell destruction marker (specifically demethylated DNA), which would enable better understanding of the beta cell decline and identification of individuals at risk of T1D development.

During treatment of diabetes mellitus by immunointervention or transplantation, it is necessary to monitor the markers of immune destruction or rejection of surviving insulin producing cells. An aim of this thesis is to improve the possibilities of following autoimmunity and to detect the survival of transplanted pancreatic islet in vivo. Partial aims included vitality testing of isolated islets for transplantation by measurement of respiration activity, observing the process of in vitro labeling of isolated islets with superparamagnetic iron oxide (SPIO) contrast agent for subsequent magnetic resonance imaging (MRI) of islets and observing SPIO particles transport after transplantation. We also studied a new dual paramagnetic contrast agent combined with fluorescein intended for identification of the MRI contrast agent in samples for histology. Further, we assessed autoimmune reaction by evaluation of cytokine response to specific stimulation with auto-antigens. We tried to affect beta-cells destruction by polyclonal anti- thymocyte antibodies in a mouse experimental model. A new method of the islet respiration measurement correlated with other methods of islet quality testing and it was suggested as a diagnostic test before clinical transplantation. Results obtained studying the intercellular...

The topic of the diploma thesis is the influence of a low-carbohydrate diet on the treatment of type 1 diabetes mellitus. It is an autoimmune disease for which it is necessary for patients to administer insulin. The selection of suitable sports activities, good health and mental condition and, above all, the adjustment of eating habits also contribute to the successful compensation of diabetes. This work demonstrates a low-carbohydrate diet as one of the possibilities diabetics can eat. The work is divided into two parts, theoretical and practical. The theoretical part briefly describes the disease and presents the recommended and a low- carbohydrate diet. The following section also addresses physical activity. It describes the issues of sports for people with diabetes who are on a regular diet, as well as on low-carbohydrate diet. The practical part shows the results of glucose sensors (Free Style Libre, Dexcom G6 and Medtronic), which continuously measure blood sugar levels. In the practical part, eight respondents with type 1 diabetes, who switched the recommended diet for a low-carbohydrate diet, were surveyed in the form of a questionnaire. The purpose of the questionnaire was to assess the effects of switching to a low- carbohydrate diet on: the compensation of diabetes; the frequency of...

The diploma thesis deals with the attitude of parents and teachers of pupils with chronic diseases in the attenuation of compulsory school attendance at the 1st stage of ordinary primary school. The objective of the work is to identify the problems that parents and teachers of chronically ill students encounter during the educational process. From this basis, the purpose is also to find the basis for the best possible cooperation between parents and teachers. The theoretical idea is represented by individual chronic diseases, namely asthma, cystic fibrosis, pediatric oncological diseases, type 1 diabetes mellitus and epilepsy. In addition, the legislative framework for the education of pupils with these diseases, the methodology of working with pupils with chronic diseases and a search of domestic and foreign research conducted on a similar topic are addressed. The methodological part is devoted to qualitative research, the main goal of which is to find out the attitudes of teachers and parents to the educational process of pupils suffering from the above diseases. Using a questionnaire survey and a semi-structured interview, it is ascertained what are the attitudes of parents and teachers towards the education of pupils with the above-mentioned types of chronic diseases in ordinary primary school....
