Brief summary
Biomarkers of kidney function in transplant medicine is an international, multicentre, observational, non-interventional study. The project is aimed at monitoring biomarkers of acute kidney dysfunction in deceased organ donors, living organ donors, and organ recipients.
Detailed description
The study is observational, without any changes from the standard care, including only selected laboratory assessments, from standard blood samples collected from the donors/recipients. Informed consent will be required from living donors and recipients. The mainly used current criteria of organ acceptability in transplant medicine include urine output and laboratory parameters of acute kidney dysfunction - serum levels of urea and creatinine. Literary sources show that these classic criteria of kidney dysfunction develop only with a significant reduction of (glomerular and tubular) kidney functions and return to normal only slowly after the function of the kidneys has been restored. New possibilities of early kidney dysfunction diagnostics are being studied, using more sensitive tests - determination of biomarkers of acute kidney dysfunction. These may serve as decisive criteria for the safe use of organs from so-called marginal donors and identify early serious impairment of kidney function in donors with preserved urine output, without fulfilled criteria of acute kidney injury.
Interventions
Baseline laboratory values will be obtained
* average hourly diuresis * hypotension MAP\<65 Torr longer than 30 minutes (YES/NO) * Furosemide administration (YES/NO) * Mannitol administration (YES/NO) * administration of anti-diuretic hormone (YES/NO) * administration of vasopressors (YES/NO) * polyuria \>3ml/kg/h (YES/NO) * nephrotoxic agents during hospitalization (YES/NO)
Laboratory values will be obtained 12 hours after reperfusion
Laboratory values will be obtained 48 hours after reperfusion
Laboratory values will be obtained 7 days after reperfusion
Laboratory values will be obtained 90 days after reperfusion
Medical information during organ harvesting/transplantation * hypotension MAP 65 Torr \> 5 minutes (YES/NO) * vasopressor support (YES/NO, duration in minutes)
Organ harvesting for transplant
Transplantation of the harvested organ

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Sensitivity of kidney dysfunction biomarkers | up to 90 days after the procedure | Sensitivity of kidney dysfunction biomarkers will be assessed using the Kidney Donor Risk Index and Kidney Donor Profile Index |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Comparison of levels of kidney dysfunction biomarkers between DBD donors (Donation after Brain Death) and DCD donors (Donation after Cardiac Death | during baseline data collection | levels of kidney dysfunction biomarkers between DBD donors (Donation after Brain Death) and DCD donors (Donation after Cardiac Death will be assessed. |
| Correlation of Acute Kidney Injury biomarkers in DCD donors with the time of warm ischemia | during organ harvesting | Correlation of Acute Kidney Injury biomarkers in DCD donors with the time of warm ischemia will be assessed. |
| Predictive value of Acute Kidney Injury biomarkers in organ recipients | up to 90 days after transplantation | The predictive value of Acute Kidney Injury biomarkers in organ recipients for worsened function of the transplanted kidney will be assessed |
| Association between donor kidney dysfunction with selected risk factors | up to 90 days after transplantation | Association between donor kidney dysfunction with selected risk factors will be assessed (ion disbalance, circulatory instability) |
