Uvod: Nedovoljan broj raspoloživih organa za transplantaciju je posledica nedovoljne
identifikacije potencijalnih moždano mrtvih davaoca u jedinicama intenzivnog lečenja i
nedovoljne konverzije potencijalnih u aktuelne davaoce iz medicinskih i organizacionih
razloga. Moždana smrt ima brojne posledice kao što su hemodinamski poremećaji,
hormonski disbalans i inflamacija, što sveukupno utiče na kvalitet organa i ishod
transplantacije. Hipoperfuzija organa donora ima za posledicu ishemijsko oštećenje i
oksidativni stres, što povećava učestalost odložene funkcije alografta (OFA). Zbog
povećane ekspresije citokina, adhezivnih molekula i antigena tkivne
histokompatibilnosti, nastale inflamatorne promene organa donora utiču na povećanje
učestalosti akutnih odbacivanja (AO) posle transplantacije. Zbog prevazilaženja ovih
poremećaja, primenjuju se različite terapijske opcije kod donora, koje su važan deo
strategije za popravljanje kvaliteta organa i ishoda transplantacije.
Ciljevi istraživanja:... Sa ciljem održavanja aktivnosti programa kadaverične
transplantacije bubrega u Kliničkom centru Srbije ispitivali smo uticaj primene
indikatora efikasnosti programa kadaverične transplantacije bubrega u periodu 2010-
2012. Pored toga, ispitivali smo efikasnost primene metil-prednizolona (MP) na
hemodinamiku i bubrežnu funkciju davaoca, kao i učestalost OFA, AO i funkciju
presađenog bubrega do kraja prve godine od transplantacije. Uzimajući u obzir
povezanost moždane smrti, oksidativnog stresa i inflamacije, određivali smo serumsku
koncentraciju 8-hidroksi 2-deoksi guanozina (8-OH-dG), trombospondina-1 (TSP-1) i
nuklearnog faktora kapa B (NF-κB) kod donora organa posle dijagnoze moždane smrti i
njihove kasnije implikacije kod primaoca.
Metode: Studija je prospektivna interventna i opservaciona sprovedena je u Centralnoj
aseptičnoj jedinici intenzivne nege Urgentnog Centra Kliničkog centra Srbije i Centru
za transplantaciju bubrega Kliničkog Centra Srbije u periodu 2010-2013. godine. U
periodu istraživanja smo analizirali tri grupe indikatora efikasnosti programa
kadaverične transplantacije koji se odnose na potencijal za donaciju organa,
organizacione nedostatke i ukupnu efikasnost programa...
Introduction: Shortage of organs available from brain dead donors is attributed to the
insufficient reporting of potential donors as well as to low conversion rates of potential
donors into actual donors due to medical and organisational issues. Brain death has
numerous consequences, including hemodynamic disorders, hormonal imbalance and
inflammation, which together influence organ quality and consequently transplantation
outcome. Hypoperfusion of donor organs leads to ischemic lesions and also increases
oxidative stress, which raises the frequency of delayed graft function (DGF). Due to
enhanced expression of cytokines, adhesion molecules and tissue histocompatibility
antigens, subsequent inflammatory changes in donor organs increase the rate of acute
rejection (AR) after transplantation. With the aim of overcoming these disorders donors
are subject to various therapy options that are an important part of the strategy for
improvement of organ quality and transplantation outcome.
Obje...ctive: With aim to maintain deceased donor kidney transplant program, we
assessed the impact of indicators of program effectiveness application in Clinical center
of Serbia, between 2010–2012. In adition, we examined the efficiency of methylprednisolone
(MP) applied to potential donors on donor hemodinamics and kidney
function, as well as frequency of DGF, AR and kidney allograft function during the first
posttransplant year. Considering the link between brain death, oxidative stress and
inflammation, we measured the serum concentration of 8-hydroxy 2-deoxy guanosine
(8-OH-dG), thrombospondin-1 (TSP-1) and nuclear factor kappa B (NF-κB) in organ
donors after diagnosed brain death, as well as their further implications in recipients.
Method: Prospective interventional and observational study was conducted in Central
aseptic intensive care unit, Emergency center, Clinical center of Serbia and Kidney
transplant center, Clinical center of Serbia. Deceased donor kidney transplant program
involved 172 potential kidney donors that were identified between 2010-2012. Brain
death was confirmed in 163 patients. We conducted an analysis of an effectiveness
indicators of deceased donor kidney transplant program. Three groups of indexes
presenting potential for donation, areas of improvement and global effectiveness
indicators were used...
