Abstract
Introduction
The method of therapy administration and injection device characteristics have been documented to influence perceptions and preference of treatment among patients with type 2 diabetes (T2D). We aimed to assess the metabolic effectiveness and patient-reported satisfaction of once-weekly semaglutide compared to liraglutide in suboptimally controlled patients with T2D.
Methods
We conducted this single-center cohort study at diabetes center clinics at a tertiary care hospital between February 2021 and August 2021. We included suboptimally controlled patients with T2D who had been treated with liraglutide for at least 3 months at baseline, then shifted to once-weekly semaglutide and followed up for the same period. Ambulatory glucose profile (AGP) metrics [i.e., mean glucose level, glycemic variability (GV), time above range (TAR), and time in range (TIR)] for baseline and follow-up were compared. To assess the satisfaction with shifting, we used the valid Arabic version of the Diabetes Treatment Satisfaction Questionnaire status (DTSQs) and change (DTSQc) while the injection device preference was assessed using the Diabetes Injection Device Preference Questionnaire (DID-PQ).
Results
We included 52 patients (25 male and 27 female), with a mean age of 48 (± 6) years and a mean diabetes mellitus duration of 7.27 (± 3.79) years. We observed a significantly decreased mean HbA1c level following semaglutide treatment (7.79% at study end vs. 8.07% at baseline, p < 0.001) and body weight (84.64 ± 7.68 vs. 87.15 ± 8.011, p < 0.001). Compared to the glucometrics data at baseline, we observed a significantly improved mean average glucose, GV, TAR, and TIR (p < 0.001). Data from the DTSQs and DTSQc questionnaires showed a high level of patient-reported satisfaction after shifting to semaglutide treatment. All patients preferred/strongly preferred once-weekly semaglutide over liraglutide in most DID-PQ questionnaire domains.
Conclusions
Switching from once-daily liraglutide to once-weekly semaglutide led to improvements in both clinical measures of glycemic control and patient-reported satisfaction.
