AbstractBackground: Diabetes mellitus is a metabolic disorder due to absolute or relative insulin deficiency. Polyuria in type 2 DM leads to loss of important water soluble nutrients in urine. In view of widespread deficiency of vitamin B12 in our country and increasing prevalence of diabetes mellitus type 2, it is considered worthwhile to assess vitamin B12 status of patients with diabetes mellitus type 2.
Material and methods: Present study comprises of 60 subjects of both sexes whom 30 are healthy controls and 30 are clinically confirmed cases of diabetes mellitus, age group ranges from 40-70 yrs. Serum separated from plain vial after centrifugation was used for estimation of serum vitamin B12 by ELISA, Plasma glucose estimation by GOD-POD Method, End Point, Glycated hemoglobin by Boronate Affinity chromatography (NycoCard).
Result: In our study it was found that serum vitamin B12 (218.24 ± 68.31 pg/ml) was significantly lower in type2 diabetes mellitus patients compared to serum vitamin B12 (254.20 ± 64.89 pg/ml) of controls. Serum vitamin B12 level (190.20 ± 19.44 pg/ml) is significantly lower in diabetes mellitus patients who were suffering from the disease for more than 3.5 years as compared to serum vitamin B12 level (257.18 ± 88.74 pg/ml) of diabetes mellitus patients who were suffering from the disease for less than 3.5 years.
Conclusion: Thus, it can be concluded that there is significant vitamin B12 deficiency in type 2 diabetes mellitus patients.
