Úvod: Odběr ledvin z dárce s nezvratnou zástavou oběhu (DCD – donor after circulatory death) je důležitou součástí transplantačních programů v celosvětovém měřítku. V České republice byla první transplantace ledvin z DCD úspěšně provedena v roce 2002. Autoři diskutují vlastní a literární zkušenosti s tímto programem. Snahou je zvýšit potenciál odběru ledvin z DCD v České republice. Metoda: Od roku 2002 do roku 2015 bylo v plzeňském Transplantačním centru odebráno celkem 44 ledvin z DCD. Technikou byl „in situ“ odběr pomocí „double baloon triple lumen“ katetru při zachování 5–10 min. „no-touch“ intervalu. Metoda hypotermické pulzatilní perfuze byla použita k testování viability odebraných ledvin. Transplantováno bylo celkem 28 ledvin příjemcům o průměrném věku 51,1 roku (26–73 let). Dle maastrichtských kritérií bylo 16 (57,1 %) ledvin ve skupině II, 8 (28,6 %) ve skupině III a 4 (14,3 %) ve skupině IV. Výsledky: 30denní pooperační mortalita byla 0 a morbidita 10,7 tj. 14,3 % (N=4). Primární afunkce ledviny byla přítomna u 2 (7,1 %), opožděný nástup funkce pak u 5 (17,9 %) nemocných. Jeden rok, 5 a 10 let po transplantaci žije 100 %; resp. 86,4 % a 76,7% nemocných a ve stejných intervalech je funkčních 92,9; 69,6 a 61,9 % transplantovaných ledvin. Dlouhodobé výsledky jsou plně srovnatelné s transplantacemi ledvin od dárců se smrtí mozku. Závěr: DCD jsou významným zdrojem ledvin pro transplantace. Transplantace ledvin z DCD je metodou logisticky, ekonomicky a personálně náročnou s velmi dobrými dlouhodobými výsledky., Introduction: Kidney procurement from donors after circulatory death (DCD) is an important part of worldwide transplantation programmes. The first kidney transplantation from DCD was successfully performed in the Czech Republic in 2002. Method: Forty four kidneys from DCD were procured in the Transplant Centre of Pilsen between 2002 and 2015. We used the technique of “in situ“ procurement with the double balloon triple lumen catheter and 5−10 minutes of the no-touch interval. The method of pulsatile hypothermic perfusion was used to test the viability of the kidneys. Twenty eight recipients with mean age 51.1 (26−73) years were transplanted. Sixteen (57.1%) kidneys were from the 2nd, 8 (28.6%) from the 3rd and 4 (14.3%) from the 4th category according to the Maastricht criteria. Results: 30-day mortality and morbidity rates were 0 and 10.7% i. e.14.3% respectively (N=4). Primary non-function was presented in 2 (7.1%), and delayed graft function in 5 (17.9%) cases. One, five and ten years of recipient and graft survival rates were 100%, 86.4% and 76.7%; and 92.9%, 69.6% and 61.9%, respectively. The long-term results are fully comparable with kidneys transplanted from donors after brain death. Conclusion: DCD are an important source for kidney transplantation. Kidney transplantation from DCD is a logistically, economically and personally demanding method with very good long-term results., and V. Třeška, T. Reischig, D. Hasman, B. Čertík, J. Moláček, R.

Ulinastatin [or called as urinary trypsin inhibitor (UTI)] plays a role in regulating neurological deficits evoked by transient cerebral ischemia. However, the underlying mechanisms still need to be determined. The present study was to examine the effects of UTI on autophagy, Nrf2-ARE and apoptosis signal pathway in the hippocampus in the process of neurological functions after cerebral ischemia using a rat model of cardiac arrest (CA). CA was induced by asphyxia followed by cardiopulmonary resuscitation (CPR) in rats. Western blot analysis was employed to determine the expression of representative autophagy (namely, Atg5, LC3, Beclin 1), p62 protein (a maker of autophagic flux), and Nrf2-ARE pathways. Neuronal apoptosis was assessed by determining expression levels of Caspase-3 and Caspase-9, and by examining terminal deoxynucleotide transferase-mediated dUTP nick-end labeling (TUNEL). The modified neurological severity score (mNSS) and spatial working memory performance were used to assess neurological deficiencies in CA rats. Our results show that CA amplified autophagy and apoptotic Caspase-3/Caspase-9, and downregulated Nrf2-ARE pathway in the hippocampus CA1 region. Systemic administration of UTI attenuated autophagy and apoptosis, and largely restored Nrf2-ARE signal pathway following cerebral ischemia and thereby alleviated neurological deficits with increasing survival of CA rats. Our data suggest that UTI improves the worsened protein expression of autophagy and apoptosis, and restores Nrf2-ARE signals in the hippocampus and this is linked to inhibition of neurological deficiencies in transient cerebral ischemia. UTI plays a beneficial role in modulating neurological deficits induced by transient cerebral ischemia via central autophagy, apoptosis and Nrf2-ARE mechanisms., Xiao-Ming Jiang, Jing-Hai Hu, Lu-Lu Wang, Chi Ma, Xu Wang, Xiao-Liang Liu., and Obsahuje bibliografii
