About this study

Eighty diabetic patients were enrolled in this study; 37 females and 43 males with inclusion criteria of vitamin B12 levels less than 233 ng/ml. The participants were divided into two groups, the Dapagliflozin group (active comparator group) received only the diabetic-controlling drug Dapagliflozin 10 mg/daily orally for twelve months, whereas, vitamin B12 and Dapagliflozin group (Experimental group) received Vit. B12 supplements as methylcobalamin 500 µg orally once daily with Dapagliflozin 10 mg/daily orally for twelve months. Glycemic control was measured by monitoring levels of HbA1c and Vitamin B12 in the participant's blood four times at time intervals of three months during the study period. Additionally, the weight measurements were recorded during the study period at time intervals of three months and BMI was calculated. The data obtained was treated by statistical analysis using SPSS software (version 20) for the significant correlation of the independent variables of the study groups after vitamin B12 supplementation.

Treatment and study plan

Vitamin B12 0.5 MG/ACTUAT

Drug

The investigators measured the blood levels of Vitamin B12 and HbA1c as well as the BMI in two study groups; The Experimental group: Vitamin B12 and Dapagliflozin group and Active Comparator group: Dapagliflozin group.

The Dapagliflozin group received only Dapagliflozin 10 mg/daily orally for twelve months, whereas, the Vitamin B12 and Dapagliflozin group received Vit. B12 supplements methylcobalamin 500 µg once daily orally with the anti-diabetic therapy Dapagliflozin 10 mg/daily orally for twelve months.
