Oxidative stress (OS) is implicated as a unifying factor between chronic kidney diseases and cardiovascular diseases. The objective of the study was to compare the oxidant and antioxidant status in patients with PD according to the state of DM. Lipoperoxides (LPO), 8-isoprostanes (8-IP) and nitric oxide (NO) were determined as oxidants and the activity of superoxide dismutase (SOD) and total antioxidant capacity (TAC) as antioxidants in patients with DM and without DM (No-DM). We included 35 patients with DM, 42 No-DM patients and 10 healthy people as a control group (HC). Patients with DM were older (p<0.0001), had higher BMI (p<0.0001), high glucose levels (p<0.0001) and more hypertension (p<0.0001). It was found that LPO levels increased in patients with DM and No-DM vs. HC (p<0.0001). There was a decrease in the levels of 8-IP in DM and No-DM compared to HC (p<0.0001). The levels of NO in patients with DM and No-DM decreased significantly compared to the HC group with 197.97±34.20 μM (p<0.0001). The activity of the SOD enzyme in patients with DM and No-DM was found to be increased compared to the HC group (p<0.0001). The levels of TAC in HC were 2.62±0.17 mM and decreased in patients with DM and No-DM (p<0.0001).
