- ACRONYMCHILD-KiTC
- hypothesisAdequate perfusion of an adult-sized renal graft in children demands significant hemodynamic changes after transplantation (Tx). Suboptimal renal graft perfusion due to inadequate hemodynamic adaptation increases the risk of loss of renal graft mass and function. This risk is especially large in the smaller and younger recipients. Current monitoring of renal graft perfusion in the post transplantation period is insufficient to detect early deterioration in blood supply. Goal of this study is to develop a non-invasive, bed-side monitor for renal perfusion after pediatric kidney transplantation. Moreover, pharmacokinetic changes after adult sized kidney transplantation in young children are largely unknown As signiflcant changes are expected, caused by increased renal and possibly hepatic blood flow, this study will investigate the pharmacokinetic (Pk) model of several pharmacons in this specific patient group.
- Healt Condition(s) or Problem(s) studiedRenal disease, Renal transplant , Live kidney donors
- Inclusion criteriaRecipients:
1)Age between 0-15 years.
2) Scheduled for living donor kidney transplantation.
3) Signed informed consent by recipient and/or parents.
4) Bodyweight maximum 40 kg

Donors:
1)Accepted as kidney donor for the pediatric recipient by the responsible doctors.
2) Signed informed consent

Parents:
1) Biological parent of the donor kidney recipient
2) Signed informed consent
- Exclusion criteriaExclusion criteria for participation of the recipients are complex congenital cardiac diseases (hemodynamic significant intracardiac shunts, cyanotic cardiac disease) and refusal of consent. Subjects with a contra-indication for MRI can be enrolled in the study to participate in all other investigations (biomarker en Pk profile, cardiac output analysis).
