Abstract
The aim of the current study was to compare antioxidant defenses and oxidative stress
markers in patients with Diabetes Mellitus (DM) and in those with Rheumatoid Arthritis
(RA). Across-sectional study was conducted with 74 participants in two distinct groups:
Diabetes Mellitus types 2, Rheumatoid Arthritis and healthy blood donors. Malondialdehyde
and uric acid were compared between these groups. Uric acid was measured as antioxidant
defenses tested in blood samples from (RA) and (DM), rather than the degree of lipid
peroxidation was measured in term of malondialdehyde (MDA). MDA level was 3.29 ± 0.59
µmol/L in control group which was significantly lower than in diabetic and Rheumatoid
arthritis patients 6.32 ± 0.84 µmol/L , 6.75 ± 0.77 µmol/L respectively with (p <0.001).
Moreover; concentrations of UA in DM was 3.65 ± 0.11 mg/dl significantly lower than in
control 4.56 ± 0.29 mg/dl with (p <0.001),conversely, we found that no significant change in
the level of UA in RA 4.23 ± 0.66 mg/dl, compared with health subjects 4.56 ± 0.28 mg/dl.
These results suggest that the feasibility to find out a new evidences for a possible
relationship between these pathologies can be found.
