Relationship between Type 2 Diabetes and Glucose-6-Phosphate Dehydrogenase (G6PD) Deficiency and Their Effect on Oxidative Stress

Objective: Though the relationship between glucose-6-phosphate dehydrogenase (G6PD) deficiency and type 2 diabetes (T2D) has been reported, their interaction to influence oxidative stress is not fully understood. This study was conducted to investigate the relationship between T2D and G6PD deficiency and assessed their effect on oxidative stress. Methodology: A total of 73 T2D and 75 non-diabetic (ND) out-patients at Enugu State University Teaching Hospital (ESUTH) in Enugu, Nigeria were recruited. They were screened for G6PD deficiency, oxidative stress markers; lipid peroxidation, protein peroxidation and glycated haemoglobin (HbA1c) and antioxidant enzymes; superoxide dismutase (SOD) and catalase activities were assayed. Results: Oxidative stress was influenced by T2D as malondialdehyde (MDA), protein carbonyl and HbA1c levels were significantly higher (p0.05) interaction between G6PD deficiency and T2D to influence oxidative stress in patients. Conclusion: The interaction between G6PD deficiency and T2D did not influence oxidative stress though there was a possible relationship between G6PD deficiency and T2D in male patients.This study was partially supported by the competitive research grant of Godfrey Okoye University, Enugu Nigeria.Published onlin
