Abstract Aim Diabetic Mellitus is the chronic metabolic disorder associated with various complications of heart, eyes, nerves, kidney etc. Diabetic Nephropathy is one of the leading causes of death in diabetic patient. We hypothesized that decrease Vitamin B12 levels is associated with Diabetic Nephropathy. Aim of our study is to study the serum Vitamin B12 levels in type 2 diabetes mellitus patients with and without nephropathy. Methods Our study population consist of 100 subjects out of which 50 cases of Diabetes Mellitus without Diabetic Nephropathy and 50 cases of Diabetes Mellitus with Diabetic Nephropathy. We measured various routine lab parameters, apart from it, we measured spot urinary albumin to creatinine ratio to assess diabetic nephropathy and in special investigation we measured serum Vitamin B12 by chemiluminesence based immunoassay. Result Serum Vitamin B12 level in the group with nephropathy (181.6 ± 17.6 pg/dl) was significantly lower than in the group without nephropathy (286 ± 30.1 pg/dl) ( p = 0.03). Conclusion Our study points towards the decrease levels of serum Vitamin B12 levels associated with the complication of diabetic mellitus such as diabetic nephropathy. So treatment of Vitamin B12 deficiency by supplementing could prevent the development and progression of diabetic nephropathy and improves the overall management of diabetic patient.
