Serum redox markers in uncomplicated type 2 diabetes mellitus accompanied with abnormal iron levels.

Objectives: This study aimed at evaluating the serum redox status in type 2 diabetes mellitus (T2DM) accompanied with an imbalance in iron concentrations.

Methods: Diabetic patients were grouped according to serum iron levels [normal (DNFe), low (DLFe), and high (DHFe)], and their clinical and redox parameters [total sulfhydryl groups (tSH), uric acid (UA), and total bilirubin (tBILI) as non-enzymatic antioxidants, and malondialdehyde (MDA) and advanced oxidation products of proteins (AOPP) as markers of oxidative stress] were determined.

Results: Glucose and HbA1c levels in the T2DM patients did not differ in function of serum iron.
