Association of NRF-2 changes in plasma and pericardial fluid with renal injury in patients undergoing cardiac surgery.

OBJECTIVE

This study was conducted to investigate the levels of nuclear factor (erythroid derivative 2)-like 2 (NRF-2), kidney injury molecule 1 (KIM-1), and heme oxygenase-1 (HO-1) in pericardial fluid (PF) and systemic circulation of patients undergoing cardiac surgery.

METHODS

This study included 40 patients undergoing cardiac surgery and 40 healthy individuals. PF and venous blood samples were obtained from the patients and renal function tests, HO-1, KIM-1, NRF-2, antioxidant, and oxidative stress parameters were studied.

RESULTS

A statistically significant difference was found in the NRF-2, KIM-1, HO-1, total antioxidant status, total oxidant status, and oxidative stress index measurements in the plasma of the patient and control groups and in the PF of the patients (p < 0.01). Compared to the control group, NRF-2, KIM-1, and HO-1 were found to be lower in the patient's plasma and PF. In the patient group, NRF-2, KIM-1, HO-1, and KIM-1 were higher in PF compared to plasma.

CONCLUSIONS

In the future, intrapericardial drug administration may improve cardiac function and prevent the adverse cardiorenal syndrome on the kidney.
