Background: Elevated plasma levels of ferritin and oxidative stress have been associated with diabetic nephropathy; the onset of which is insidious. The early stages of glomerular hyper filtration often go unnoticed in the majority of subjects. This limit the precision of creatinine based glomerular filtration rate estimates. Objective: We sought to document the role of plasma ferritin and oxidative stress markers in the early detection of nephropathy in diabetes mellitus (DM). Subjects and Methods: This was a cross sectional analytical study conducted on 360 participants, comprising of 220 with DM and 140 age matched apparently healthy control individuals. Fasting blood samples were collected for the estimations of glucose, plasma ferritin, urea, creatinine and oxidative stress markers (malondialdehyde, superoxide dismutase, reduced glutathione and catalase). Results: The mean ferritin levels in DM (83.77 ± 4.18 ng/ml) was significantly higher than the controls (55.60 ± 10.41ng/ml) (p = 0.004) . A significant correlation of ferritin and malondiadehyde (r = 0.422, p = 0.050) was observed in DM. Inverse associations of creatinine and superoxide dismutase (r = -0.298, p = 0.011), as well creatinine and catalase (r = -0.270, p = 0.022) were observed in DM. Possible predictors of nephropathy include ferritin, superoxide dismutase, catalase and reduced glutathione. Conclusion: Elevated plasma ferritin levels in addition to some antioxidant enzymes, notably superoxide dismutase and catalase, contribute to the pathogenesis of nephropathy in DM.
