This study aimed to investigate the efect of dulaglutide on the number and function of endothelial progenitor cels (EPCs) in the peripheral blod of patients with T2DM and its role in improving arterial elasticity, so as to determine potential mechanisms of preventive efect of dulaglutide on ASCVD.Sixty patients with T2DM were treated with 10 mg/day of metformin and randomly divided into two groups for 12 weks: metformin monotherapy group (MET group, n = 30), and metformin combined with dulaglutide group (MET-DUL group, n = 30).
Key Information
Before and after treatment, the number of CD34+CD13+KDR+ EPCs and the brachialβankle pulse wave velocity (baPWV) of the participants were measured, and EPC proliferation, adhesion, migration, and tubule formation were asesed in vitro.There were no significant diferences in the number and function of EPCs and baPWV changes in MET group (P > 0.05). In MET-DUL group, nitric oxide (NO) levels and the number of EPCs increased after treatment (P < 0.05), while the levels of C-reactive protein (CRP), interleukin-6 (IL-6), tumour necrosis factor-Ξ± (TNF-Ξ±), advanced glycation end products (AGEs), and baPWV decreased (P < 0.05).
EPC proliferation, adhesion, migration, and tubule formation abilities were significantly enhanced (P < 0.05). Corelation analysis showed that in MET-DUL group, the changes in CRP, IL-6, TNF-Ξ±, and AGEs were negatively corelated with the number of EPCs and their proliferation and migration abilities (P < 0.05). Body weight, NO, CRP, and IL-6 levels were independent factors afecting the number of EPCs (P < 0.05).
