Изучение количества циркулирующих прогениторных клеток эндотелия у больных сахарным диабетом 1 типа

Abstract

Aim. Circulating progenitor endothelial cells (CPCs) play an important role in the regeneration of damaged vascular endothelium. We aimed to study the effect of type 1 diabetes mellitus (DM) on the number of different lines of CPCs.Methods. The number of different lines of CPCs was evaluated by flow cytometry in 45 patients with type 1 DM (mean age: 26,6±6,5 years) of different duration and 14 healthy volunteers.Results. The number of CPCs in the peripheral blood flow of patients with type 1 DM was significanlty reduced compared with that in healthy volunteers and had a reliable inverse correlation with glycated haemoglobin (HbA1c).Conclusions. The number of CPCs in the peripheral blood flow of patients with type 1 DM depended on the level of DM compensation. Of the different lines of CPCs, Lin-CD34+ cells were significantly reduced by 42% (p=0,006), Lin-CD34+c-Kit- cells by 42% (p=0,007) and Lin-CD34+c-Kit+ cells by 41% (p=0,022). Thus, the number of CPCs in the peripheral blood of patients with type 1 DM is reduced with higher levels of HbA1c.
