Impact of Dapagliflozin as add-on therapy on glycemic status and quality of life in type 2 diabetic patients

Evaluate the efficacy of dapagliflozin on glycaemic and non-glycaemic indices and assess quality of life in type 2 diabetes patients (T2DM) with inadequate glycaemic control on three oral antidiabetic agents (OADs). Patients with uncontrolled type 2 diabetes [Haemoglobin A1c 7.0%-12.0%] on sulfonylurea, metformin and gliptin were selected to receive dapagliflozin 5mg/day for 16 weeks (n=40). Fasting and postprandial plasma glucose, glycated haemoglobin A1c, body weight, and waist circumference were measured. Assessment of patients’ quality of life was performed using Quality of Life Scale for Iraqi Diabetic patients (QOLSID) at baseline and after administration of dapagliflozin. Dapagliflozin showed high significant reduction in fasting and postprandial plasma glucose, glycated haemoglobin A1c (HbA1c), body mass index (BMI) and index of central obesity (ICO) (p<0.001). High significant changes in the QOLSID score after treatment (p<0.001). High BMI is negative predictor for patients’ quality of life. Dapagliflozin improved both glycaemic and non-glycaemic parameters in T2DM patients who already on three OADs. This is promising results in short period makes the treatment a suitable alternative to insulin specially in patients not prefer to use injected medication. Dapagliflozin showed an improvement in the patients’ physical and psychological condition and consequently overall QOL.
