INTERRELATIONS BETWEEN INFLAMMATORY AND OXIDATIVE STRESS BIOMARKERS IN OBESE WOMEN WITH TWO COMPLICATIONS (HYPERTENSION, DIABETES)
Inflammation and oxidative stress in women obesity.
Background and aims : Interaction between oxidative stress and inflammation has not been comprehensively investigated in the association obesity – diabetes - hypertension. Our aim was to investigate interrelations between inflammatory and oxidative stress biomarkers in obese women with two complications (hypertension, type 2 diabetes). Material and Methods: 54 obese without complications, 46 diabetic obese, 48 hypertensive diabetic obese women, and 120 healthy controls were recruited from the department of nuclear medicine (Algeria). Inflammatory and oxidative stress biomarkers were assayed by appropriate methods. Results: Inflammatory markers were significantly higher in all obese groups compared to controls. Elevated pro-oxidants and decreased antioxidant markers were noted in obese women. These alterations were accentuated when obesity was associated with hypertension and diabetes. A positive interrelationship between inflammatory mediators and oxidative status, and a negative one with antioxidants were noted during obesity. Hypertension and diabetes enhanced these correlations. Leptin, C-reactive protein, catalase, superoxide dismutase, ion superoxide, peroxynitrite were found to be the best inflammatory and oxidative stress biomarkers that can predict diabetes and hypertension in obese women. Conclusions: oxidative stress and inflammation were intimately interconnected in women obesity associated with diabetes and hypertension.
