Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Endothelial lesions within the transplanted kidney are a major determinant of chronic allograft nephropathy. Epoxyeicosatrienoic acids (EETs) are endothelium-derived hyperpolarizing factors with anti-inflammatory, antiproliferative and vasodilator properties.

The main goal of the investigators' study is to evaluate whether genetic polymorphisms of specific enzymes responsible for the bioavailability of EETs are associated with post-transplant kidney function.

To this end, 80 kidney transplant recipients will be included. Prespecified genetic polymorphisms of CYP 2J2, CYP 2C8, CYP 2C9, CYP 2C9, CYP 2C19 and EPHX2 will be determined. Kidney function will be recorded 3, 6, 12 and 36 months after transplantation. Flow-mediated dilatation, EETs and circulating biomarkers of endothelial function will be measured in the radial artery.

The expected results of this study to provide preliminary evidence supporting a beneficial role of an increase in the bioavailability of EETs in kidney transplant recipients.
