Brief Summary

Kidney and liver transplantation are the treatment of choice and are often the last therapeutic option offered to patients with chronic renal and liver failure. More than 70% of kidneys and liver available for transplantation are obtained from donors following neurological death. Unfortunately, compared to living donation, transplant function, graft survival, and recipient survival are consistently inferior with kidneys and liver from neurologically deceased donors. This difference lies with the exacerbated pro-inflammatory state characteristic of deceased donors. Indeed, when neurologic death occurs, the immune system releases substances in the blood that could harm organs and particularly the liver and the kidneys. We believe that achieving a better understanding of the inflammatory processes of organ donors could be greatly informative to design future randomized controlled trial assessing the effect of personalized immunosuppressive therapy on organ donors to ultimately improve the care provided to donors so as to increase the number of organs available for transplantation and enhancing the survival of received grafts

Outcome Measures

Primary Outcomes (1)

  • Kidney delayed graft function

    Requirement for renal replacement therapy within the first 7 days following transplantation or decrease of \< 10% of creatinine after 3 days after transplantation, or creatinine \> 250 µmol/l at day 5 with evidence of delayed graft function by renal scintigraphy

    7-days post-transplantation

Secondary Outcomes (5)

  • Liver early graft dysfunction

    7-days post-transplantation

  • Quantification of circulatory cytokines

    From ICU admission up to organ recovery (5 timepoints(1:ICU admission; 2: consent to organ donation, 3: 4 to 8 hours after sample #2, 4: 24 hours after sample #2; 5: prior to transfer from ICU to operating room); 25 donors).

  • Identification of inflammatory-related miRNA targets using micro-transcriptome analyses

    From ICU admission up to organ recovery (5 timepoints (1:ICU admission; 2: consent to organ donation, 3: 4 to 8 hours after sample #2, 4: 24 hours after sample #2; 5: prior to transfer from ICU to operating room) ;25 donors).

  • Validation of inflammatory-related miRNA targets using targeted quantification

    From ICU admission up to organ recovery (5 timepoints(1:ICU admission; 2: consent to organ donation, 3: 4 to 8 hours after sample #2, 4: 24 hours after sample #2; 5: prior to transfer from ICU to operating room); 105 donors).

  • Validation of circulatory cytokines

Biospecimen

Retention: SAMPLES WITH DNA

Blood samples (including miRNA and buffy coat) will be drawn at 5 specific time points: following ICU admission when patient has a serious neurological lesion, as soon as possible after consent to organ donation, as well as 4 to 8 hours and 24 hours after the first sample of phase 2 has been drawn. A final draw will be made prior to transfer from the ICU to operating room for organ recovery. A substudy will be conducted in some centers and we will collect samples at time of aortic cross clamp during surgery
