The use of semaglutide as an add-on therapy in patients with latent autoimmune diabetes in adults

J Clin Endocrinol MetabPublished Retrospective cohort study

Authors' conclusion

Semaglutide as an add-on treatment to insulin exerted relevant clinical beneficial effects on the glycometabolic control in patients with LADA. These effects are enhanced in those patients with preserved β-cell function.

Study context

Population
Patients with latent autoimmune diabetes in adults (LADA) treated with insulin68 continued ≥6 months
Participants
80 patients
Exposure
Semaglutide add-on to insulin
  • Semaglutiden = 80
Outcome
Glycometabolic parameters in semaglutide users
Follow-up
6 months

Main finding

As reported in the abstract

  • Significant reduction in HbA1c, BMI and insulin total daily dose
  • Serum C-peptide and TIR increased, without changes in TBR

Observational data: associations, not effects.

Further findings

Subgroup by residual β-cell function

Residual β-cell function: higher BMI and insulin total daily dose reduction
Preserved β-cell mass: greater TIR improvement vs poor C-peptide production
