protein oxidation through oxidative stress, which represents the overall status of the protein in the cell/tissue. Due to their increased levels of AOPPs were reported during T2DM. The aim of this study was to assess AOPP level in T2DM subjects with foot ulcer (DFU) and explore its correlation with infection. Type 2 diabetic patients (n=108) and healthy subjects (n=25) were enrolled in this study. The T2DM group was subdivided to diabetic patients without complications (n=25) and eighty-three (83) of them have diabetic foot. They were sub- grouped into two groups according to presence Osteomyelitis and abscess, and in reliance on medical analysis of WBC count and CRP. Group of diabetic without superficial or deep ulcer and no osteomyelitis or abscess G(0,1,2) (n =45), which consist patients with grades (0,1,2), and group of diabetic with deep ulcer abscess and osteomyelitis G(3,4,5)(n = 38) that consist patients with grade (3,4,5). Twenty- five (25) non-diabetic apparently healthy subjects serve as control (group C) were enrolled. The Biochemical analysis was done for all participants such as serum glucose, hemoglobin A1C, insulin, lipid profile, WBC, and C-reactive protein (CRP). Serum AOPP concentration was determined using an enzyme-linked immunosorbent assay kit. The oxidative status was assessed by measuring catalase activity, glutathione (GSH), malondialdehyde (MDA) and total thiol levels. AOPP, MDA, WBC, and CRP, were significantly higher in G (0,1,2) and G (3,4,5) groups in comparison to control group, while GSH and total thiol levels were significantly lower as compared with control group. The outcomes of this study reveal the incidence of oxidative stress among DFU patients with higher Wagner grades and the presence of relation between inflammation state in DFU subjects and oxidative stress.
