This study conducted a systematic review and meta-analysis to evaluate the efficacy and safety of sitagliptin combined with insulin for LADA. The results showed that sitagliptin combined with insulin can achieve better glycemic control, improve islet beta-cell function, and have a lower incidence of hypoglycemia compared with insulin alone.
Aims/Introduction The optimal therapy for latent autoimmune diabetes in adults (LADA) remains undefined. Increasing evidence has shown that sitagliptin and insulin treatment can benefit patients with LADA, but the efficacy still lacks systematic evaluation. We carried out this systematic review and meta-analysis to summarize the current data on the efficacy and safety of sitagliptin combined with insulin on LADA, providing a reliable reference for the effective therapeutic treatment of LADA patients. Materials and Methods We retrieved the literature in PubMed, Cochrane Library, Embase, Web of Science and CNKI from inception to August 2021. Randomized controlled trials comparing the effects of sitagliptin plus insulin with insulin alone in LADA patients were identified. The outcome measures included parameters of glycemic control, beta-cell function, body mass index and adverse events. The Review Manager 5.2 and Stata 14.0 were utilized for data analysis. Results Eight randomized controlled trials involving 295 participants were identified. Sitagliptin and insulin treatment lowered hemoglobin A1c (weighted mean difference -0.36, 95% confidence interval -0.61 to -0.10, I-2 = 91.6%), increased fasting C-peptide (weighted mean difference 0.08, 95% confidence interval -0.02 to 0.17, I-2 = 88.8%) and had fewer adverse events compared with insulin alone. The inter-study heterogeneity, potential publication bias and other factors might interpret asymmetrical presentation of funnel plots. There was no significant association between sitagliptin plus insulin treatment and levels of hemoglobin A1c or fasting C-peptide, regardless of the duration of intervention and sample size. Conclusions Sitagliptin combined with insulin can achieve better glycemic control and improve islet beta-cell function with lower incidence of hypoglycemia compared with insulin alone, which provides an effective and tolerated therapeutic regimen for LADA patients. However, further well-designed and rigorous randomized controlled trials are required to validate this benefit due to the limited methodology quality of included trials.
