HLA typizace v klinické praxi - využití k testování predispozic k onemocněním autoimunitního typu
VESELÁ, Dominika
Autoimmune diseases require the interplay of internal (genetic) and external (environmental) factors to develop and erupt. The essential genetic factors include HLA alleles, whose carrying is associated with a significant predisposition to the development of a specific autoimmune disease. This Master Thesis deals with the problematics of autoimmune diseases associated with HLA system. The practical part focuses on the examination of predisposing alleles related to celiac disease as one of the most widespread autoimmune disease, which many scientific teams are dealing with, but even in the Czech Republic there are not enough population studies of this disease. Thanks to data from genetic laboratory GENLABS s.r.o. in České Budějovice, ÚHKT and VFN in Prague it was possible to focus on such population study.

Moravcová, Lucie ; Řeháček, Vít (advisor) ; Jílek, Petr (referee)
8 ABSTRACT Author: Bc. Lucie Moravcová Supervisor: MUDr. Vít Řeháček Charles University, Faculty of Pharmacy in Hradec Králové Title of master's thesis: Kidney transplantation: donor-recipient pairing in University Hospital Hradec Králové Background: The aim of this study was to determine HLA, blood group, age and sex match in donor-recipient pairing in kidney transplantation. HLA alleles of deceased donors were typed in Transfusion Department of the University Hospital Hradec Králové. Methods: Donor's HLA-A*, HLA-B* and HLA-DRB1* alleles were typed by PCR - SSP method. Complex data evaluating and processing was then performed. Results: 97 deceased donors were tested between 2013 and 2018. A total of 98 kidneys received from them were subsequently transplanted to 98 recipients in University Hospital Hradec Králové. 60,2 % of the donors were men, 63,3 % of the recipients were men. Most of the donors, as well as the recipients, were 51-70 years old (50,0 % and 59,2 %, respectively). The most common diagnoses in the group of deceased donors were associated with brain damage (66,3 %), the most common cause of renal failure in the group of recipients was chronic inflammatory kidney disease (41,8 %). All 98 transplantations (100,0 %) were AB0 compatible. 74 transplantations (75,5 %) were RhD compatible. 5...

The role of B cells in transplantation reactions
Brožová, Jitka ; Slavčev, Antonij (advisor) ; Stříž, Ilja (referee)
Kidney transplantation is the best treatment for patients with end-stage renal failure. The main problem of kidney transplantation is however the development of a cellular and antibody-mediated (humoral) rejection. During the last decade, thanks to the advanced immunosuppression, prognosis of survival and function of transplanted organs has significantly improved. Nevertheless, humoral rejection remains very serious obstacle in high-risk patients, because it can permanently damage the graft. Therefore, before transplantation it is necessary to stratify patients into high and low risk groups for development of antibody-mediated rejection. Current immunogenetic tests performed before transplantation include, in addition to HLA typing, detection of panel-reactive antibodies. However, this test does not provide information about B cells which participate in the humoral response of the kidney recipient. Therefore, in the presented thesis we studied B cell reactivity and its regulation in transplanted patients. In this retrospective analysis we measured levels of the B cell activating factor, a cytokine regulating the function of B lymphocytes (BAFF). Current reports suggest that BAFF could serve as a marker of humoral rejection. Furthermore, we focused on B lymphocytes and their capacity to produce...
