Aims: Diabetes patients with renal impairment commonly have a degree of hematological abnormalities than those non-diabetics with chronic kidney disease. The present study aimed to clarify the association between oxidative stress and hematological abnormalities with the progression of diabetic nephropathy.
Methods: A total of 20 healthy subjects and 100 patients were enrolled in the study. Eligible renal dysfunction patients were classified according to biochemical markers into five groups (20 patients); diabetic patients, pre-renal failure patients, diabetic pre-renal failure patients, renal failure patients, and diabetic renal failure patients.
Results: Erythrocytes and platelets count, hemoglobin and hematocrit levels revealed a significant decrease in all renal dysfunction groups, while leukocytes count, red cell distribution width, platelet distribution width, and mean platelet volume showed significant increases in diabetic and renal dysfunction groups as compared to the healthy control. Nitric oxide level increased significantly, while reduced glutathione showed a marked decrease in diabetic and all renal dysfunction groups compared to the healthy control.
Conclusion: Nitric oxide and reduced glutathione were associated with the inflammatory status in diabetic renal dysfunction patients which reflected by elevation in leukocytes and neutrophils count, red cell distribution width as well as the reduction in values of erythrocytes, platelets count, hemoglobin and hematocrit. Therefore, hematological indices can play a role in predict the progression of diabetic nephropathy.
