Outline of Final Research Achievements |
The prevention of ischemia-reperfusion injury (IRI) is important for both early and long-term graft function, especially when using extended-criteria or donation after cardiac donors. Hydrogen sulfide (H2S) has recently been reported to have both anti-inflammatory and cytoprotective effects. We investigated the effectiveness and optimal method of administration of H2S for renal IRI using miniature swine. H2S therapy significantly reduced the increase of serum creatinine levels of 120-min warm ischemic kidney. Furthermore, beneficial effects of selective H2S administration directly to the kidney was more prominent than systemic intravenous H2S administration. Further work investigating the benefits of H2S for organ procurement and preservation using ex-vivo normothermic machine perfusion system may allow for improved outcomes of renal transplantation.
