Background: Extreme alterations in hematological values and inflammatory biomarkers affecting dependent variables in clinical tests are associated with type-2 diabetes mellitus and anemia. Objective: To investigate some hematological and inflammatory risk factors and their relation in developinginsulin resistance in anemic type-2 diabetes mellitus. Patients and Methods: This case-control study was conducted in 190 patients and healthy subjects in the hospital of Layla Qasim Center in Erbil city and ethical clearance was obtained from the university ethical review committee. The included subjects were divided into three groups: non-diabetic (control) group, non-anemic type-2 diabetes mellitus, and anemic type-2 diabetes mellitus. Blood samples were analyzed for hematological parameters by Coulter counter analyzer, and biochemical tests included glycated hemoglobin, fasting blood glucose, insulin, and some inflammatory biomarkers by spectrophotometry and standard sandwich enzyme-linked immunoassay. Harvested data were analyzed by the statistical package for social science version 23. Results: The results showed remarkable alterations in glycated hemoglobin, red and white blood corpuscles, and inflammatory parameters in anemic type-2 diabetes mellitus compared to non-anemic type-2 diabetes mellitus. Inflammatory parameters including interleukin-1 and tumor necrosis factor-alpha exhibited a strong positive correlation with anemic diabetes than non-anemic diabetes. Conclusion: We concluded that some hematological and biochemical parameters were positively related to developing anemic type-2 diabetes mellitus and can be helpful as diagnosing tools for predicting the progression of anemic type-2 diabetes mellitus.
