Serum ferritin level in type 2 diabetic patients with renal dysfunction

Abstract

Background and objective: Nephropathy is the major cause of end-stage renal disease (ESRD) in type 2 diabetes mellitus (T2DM). Delay in identification and management of nephropathy in T2DM may cause development of ESRD. An increased level of serum ferritin plays a role in the pathogenesis of chronic kidney disease (CKD) in T2DM. Hence, the present study intended to assess the level of serum ferritin in renal dysfunction in patients with T2DM. Material and methods: This was a retrospective study with 81 T2DM patients with and without nephropathy. They were categorized into two groups. Group-1 consisted of 46 T2DM cases without nephropathy and remaining 35 with nephropathy.The clinical and biochemical parameters such as blood glucose, urea, creatinine, iron, ferritin, transferrin, total iron binding capacity (TIBC), and haemoglobin were measured by standard methods, and estimated glomerular filtration rate (eGFR) by MDRD formula. Results: Significantly (p<0.05) elevated level of serum ferritin along with urea and creatinine was found in patients with T2DM with nephropathy.A significant positive correlation (r = 0.37) of serum ferritin and negative correlation (r = - 0.852) of eGFR with creatinine were found. It indicated that ferritin could be a good marker to monitor kidney function in T2DM. Conclusion: Apart from eGFR and serum creatinine, raised serum ferritin level was a good indicator of renal dysfunction in T2DM patients and might play an important role in renal dysfunction in early stage diabetic nephropathy.
