Patienters upplevelser i förhållande till avstötning eller risk för avstötning efter en organtransplantation. / Patients experiences in relation to rejection or the risk of rejection after an organ transplant.Karlström, Josefin, Jonasson, Malin January 2016 (has links)
Varje år genomförs omkring 700 organtransplantationer i Sverige. Patienter som genomgått en organtransplantation har en ständig risk för avstötning. Avstötning innebär att det transplanterade organet stöts bort och slutar fungera på grund av kroppens immunförsvar. Oavsett var transplantationen utförs så följs patienterna upp på sin hemort. Därför är det av stor vikt att som sjuksköterska inneha kunskaper om patienters upplevelser om avstötning. Syftet med litteraturstudien var därför att beskriva patienters upplevelser om avstötning efter en organtransplantation. För att uppnå syftet med studien utfördes en litteraturstudie, där fyra kategorier framstod i resultatet: Det ständiga hotet, En oönskad livssituation, Fångad i behandlingsregimen och Att finna styrka i vardagen. Avstötning är en upplevelse av ett ständigt hot som även kan medföra att patienter upplever ett emotionellt trauma. Patienterna känner sig tvungna att följa den utvalda behandlingsregimen för att undvika en avstötning. Efter en upplevd avstötning behöver patienterna använda sig av olika strategier för att kunna hantera vardagen. Ytterligare forskning om ämnet behövs för att kunna möta denna patientgrupps vårdbehov. / Each year about 700 organ transplants are performed in Sweden. Patients who have had an organ transplant are at constant risk of graft rejection. Graft rejection means that the transplanted organ is rejected and stops functioning because of the body’s immune system. Regardless of where the transplant is performed the patients are followed up at their domicile. Therefore it is of great importance that the nurse has knowledge about patients’ experiences in conjunction with graft rejection. The purpose of this study was to describe patients' experiences of graft rejection after organ transplantation. To achieve the purpose of this study a literature review was conducted, in which four categories emerged in the results: The constant threat, An undesirable situation in life, Caught in the treatment regimen, and To find strength in everyday life. Rejection is an experience of a constant threat that may cause patients to experience an emotional trauma. Patients feel obliged to follow the chosen treatment regimen to prevent rejection. After an experienced rejection, patients need to use different strategies to cope with everyday life. Further research on the topic is needed to meet the care needs of this patient group.

Allogeneic CD4+CD25+Foxp3+ T Regulatory Cells in Autoimmunity and Transplantation Tolerance: Therapeutic Potential and TCR Repertoire RequirementAdeegbe, Dennis O. 28 March 2008 (has links)
CD4+CD25+Foxp3+ T regulatory (Treg) cells are critical in maintaining self tolerance and promoting the acceptance of allogeneic tissue/organ grafts. To be widely applied in clinical settings, there needs to be a readily available source of Treg cells, a requirement that is better met if non-histocompatible donor cells could be utilized in adoptive therapy. Therefore, to investigate the therapeutic potential of fully allogeneic Treg cells to control autoimmune disease or allograft rejection, we utilized IL-2R beta-deficient mice that exhibit rapid lethal autoimmunity due to low production of an ineffective population of Treg cells. We show that adoptive transfer of MHC-mismatched Treg cells into IL-2R beta-/- mice resulted in life-long engraftment of the donor cells, which exhibited skewed reactivity toward host alloantigens, and prevented autoimmunity. When such animals received skin grafts, they exhibited tolerance to those grafts that expressed MHC molecules from which the donor Treg cells were derived. Collectively, these data provide proof-of-principle that effective engraftment by allogeneic Treg cells controls autoimmunity and leads to favorable conditions for long-term acceptance of allografts. Current data indicates that CD4+CD25+Foxp3+ Treg cells exhibit a broad TCR repertoire. However, the relationship between this diversity and capacity to control a similarly diverse population of potentially autoreactive T cells remains to be defined. To investigate this issue, we assessed the TCR repertoire of chimeric donor Treg cells in IL-2R beta-/- mice that were adoptively treated with a diverse polyclonal Treg inoculums. We demonstrate that autoimmune disease was fully prevented by engrafted donor Treg cells in spite of a TCR repertoire that is less diverse than the input cells. However, in settings where the input TCR repertoire is limited by utilizing donor Treg cells that express a single TCR beta chain, control of disease was hampered, correlating with a limited TCR alpha repertoire within the engrafting donor Treg cells. Collectively, these findings suggest that for adoptive therapy, a diverse TCR repertoire of input Treg cell inoculums is an essential requirement for effective control of polyclonal autoreactive T cells but perturbations in the repertoire that results in significant limitation to this diversity may compromise Treg cell efficacy at fully keeping autoaggressive cells in check.
