Protein oxidation in Type 2 diabetic patients on hemodialysis

We conclude that PCO level increases in DM patients, and this increase is more profound in DHD patients, indicating that both diabetes and dialysis contribute to increased protein oxidation. The low P-SH level in DHD patients, but not in DM patients, suggests that dialysis is responsible for this decrease. We propose plasma PCO derivate as a novel specific marker for oxidative protein damage.
