Background:Serum C-reactive protein (CRP) and ferritin are two acute phase reactants. CRP may be related to metabolic syndrome and ferritin which in turn could cause resistance to insulin and dysfunction of b cells of pancreases. The aim of the study was the evaluation of the relationship of these two acute phase reactants with some indices of diabetic control.Materials and Methods:In a quasi-experimental study, 67 patients with type 2 diabetes, serum CRP, ferritin, Fasting Blood Sugar (FBS), post prandial BS, Hemoglobin A1c (HbA1c), triglyceride, Low Density Lipoprotein Cholesterol (LDL) and High Density Lipoprotein cholesterol (HDL) were checked before and 3 months after the control of hyperglycemia and hyperlipidemia.Results:The mean age of the patients was 56.5 ± 9.7 (30 to 82) years. There was no significant difference between CRP before and after study; however, serum ferritin significantly decreased after study with control of hyperglycemia. FBS, 2 hours post-prandial blood sugar (2hppBS), HbA1c and triglyceride of patients decreased significantly after control of hyperglycemia and hyperlipidemia (P < 0.05); however, HDL and LDL cholesterol didn’t change (P > 0.05).Conclusion:Based on our results, serum ferritin decreased after decline of patients’ blood sugar, so might be we used it as one of the diabetes control indices for diabetic patients.
