AbstractObjective: Great interest is directed to inflammation and oxidative stress involvement in type 2 diabetes pathogenesis. Many researchers suggest they play roles but exactly how is still not clear enough. This encouraged us to investigate relations and potential inter-relationships between them and insulin resistance in type 2 diabetes in its early stage. Whether metformin drug alone, as frequently prescribed, is enough for type 2 diabetes management in this early stage was an objective.Methods: Blood sugar indices, adiponectin (ADIPOQ), tumor necrosis factor-Î± (TNF-Î±), malondialdehyde (MDA), nitric oxide (NO), C-reactive protein (CRP), liver and kidney function tests and lipid profile were monitored in non-diabetic volunteers, pre-diabetic and newly diagnosed type 2 diabetic patients before and after metformin drug utilization for 5 mo.Results: MDA, inflammation markers and alanine aminotransferase (ALT) were elevated, and blood sugar indices and lipid profile showed pathological alterations in diabetics compared to non-diabetics; changes were worse in type 2 cases. They were improved to different degrees by metformin treatment except for pancreatic Î²-cells function and ADIPOQ level showed no significant improvements and it couldn't normalize ALT.Conclusion: Results reflected significant relations and inter-relationships between oxidative stress and inflammation markers in type 2 diabetes in its early stage and indicated that metformin may need to be combined with another drug.Â
