Real-world effectiveness of sodium glucose transporter 2 inhibitors among youth with type 2 diabetes.

Objectives: Clinical trials of sodium-glucose transporter 2 inhibitors (SGLT2i) in youth with type 2 diabetes (T2D) showed significant improvement in HbA1c% and fasting plasma glucose, yet there is limited real-world data on their use. This study sought to assess real-world use and effectiveness of SGLT2i medications in management of T2D in a diverse cohort of youth.

Methods: This retrospective study analyzed youth newly prescribed a SGLT2i for management of T2D at two academic pediatric diabetes centers. Change in HbA1c, BMI, and insulin use from baseline to follow-up were evaluated for those taking SGLT2i added to their background diabetes treatment. Wilcoxon signed-rank test and McNemar's test were used to compare paired continuous and categorical variables, respectively.

Results: A total of 81 patients with youth-onset T2D (mean age 17.3 years (SD 1.93), 63 % female, 51 % non-Hispanic Black, 13 % Hispanic, 33 % with private insurance) were prescribed SGLT2i. Among the 61 (75 %) reporting adherence or partial adherence at a median follow-up of 98 days, median HbA1c decreased from 8.4 to 7.1 % (p<0.001). There was a small but significant reduction in mean BMI Z-score from baseline to follow-up (2.66 to 2.57, p=0.0004). The proportion of patients prescribed basal insulin decreased from 44 to 34 % (p=0.03), and prandial insulin from 23 to 13 % (p=0.01).

Conclusions: Real-world use of SGLT2i in youth with T2D is associated with decreased HbA1c levels and lower BMI Z-score and may also reduce use of insulin for youth with T2D.
