Effects of incretin-based therapies on β-cell function in type 1 diabetes mellitus: a systematic review and meta-analysis.

Abstract

AIM:

To assess the effects of incretin-based therapies on β-cell function in patients with type 1 diabetes mellitus (T1DM).

METHODS:

We searched the PubMed, Cochrane Library, Embase, and Web of Knowledge databases for eligible randomized clinical trials published up to July 2021. The inclusion criteria were patients with T1DM or latent autoimmune diabetes in adults, patients treated with dipeptidyl peptidase-4 inhibitors or glucagon like peptide-1 receptor agonists, and outcomes included one of the following: fasting plasma glucose, fasting C-peptide, postprandial C-peptide, C-peptide area under the curve (AUC), homeostasis model assessment for β cell function, and insulin resistance. The effects were analyzed using a random effect model with STATA 11.0.

RESULTS:

Eight trials including 427 participants were included in the final analysis. A pooled analysis found no significant difference in fasting plasma glucose, fasting C-peptide, postprandial C-peptide, or C-peptide AUC between patients treated with incretin-based therapies and placebo. The two trials that reported changes in 2-hour postprandial C-peptide and two of the four trials that reported changes in C-peptide AUC reported increases after incretin-based therapies.

CONCLUSION:

This meta-analysis showed that incretin-based therapies did not preserve β-cell function in patients with T1DM.
