A short-term follow-up of glycemic and body weight changes in diabetic patients who replaced dipeptidyl peptidase-4 inhibitors with the sodium-glucose cotransporter 2 inhibitor empagliflozin
Abstract
BACKGROUND: Sodium-glucose cotransporter 2 inhibitors (SGLT2is, gliflozins) are associated with lower all-cause mortality than other anti-diabetic agents in patients with type 2 diabetes. In patients who may benefit from SGLT2is, but cannot add them to a dipeptidyl peptidase-4 inhibitor (DPP4i, gliptin) treatment for various reasons, replacement of the DPP4i with a SGLT2i may be considered.
OBJECTIVES: Evaluate changes in metabolic parameters in patients with diabetes after replacing a DPP4i with the SGLT2i empagliflozin.
DESIGN: Panel study (cross-sectional and cohort hybrid).
SETTING: The diabetes outpatient clinics of Chang Gung Memorial Hospital at Linkou, a university hospital in Taiwan.
PATIENTS AND METHODS: We reviewed the medical records of patients who had been treated with anti-diabetic agents including a DPP4i between May 2016 and May 2017. Patients who switched from DPP4is to empagliflozin (switched-to-empagliflozin group) without changes to other anti-diabetic agents for at least 6 months were compared patients who continued taking an original antidiabetic agent. The body weight (BW), body mass index (BMI), and glycated hemoglobin (HbA1c) level at baseline and after 3 and 6 months were collected for analysis.
MAIN OUTCOME MEASURES: BW, BMI, HbA1c at baseline, 3 and 6 months.
SAMPLE SIZE: 236 patients.
RESULTS: The HbA1c level and BMI of 110 patients (71%) in the switched-to-empagliflozin group were significantly reduced at 6 months after the switch, and there…
