Resumo

Systemic lupus erythematosus (SLE) is an autoimmune disease of unknown origin associated with oxidative stress. The present study aimed to investigate the presence of oxidative stress in patients with newly diagnosed SLE. SLE patients (n = 36) and control subjects (n = 28) were enrolled in this study. Blood samples were used for malondialdehyde (MDA), sulfhydryl groups (SH) and uric acid determination. MDA levels (µmol/L) were higher in patients (3.9 ± 2.6) than in control subjects (1.6 ± 2.6). SH were significantly lower in SLE patients. The findings suggest that MDA can be a good marker of oxidative stress in SLE.
