Resumo
The present study evaluated the cells and cytokine of maternal blood, cord blood and colostrum of diabetic mothers. The women evaluated were divided according to their body mass index (BMI) and glycemic status into non-diabetic (ND - N = 15), mild gestational hyperglycemic (MGH - N = 15), diabetes mellitus gestational (DMG - N = 13) and type-2 diabetes mellitus (DM2 - N = 15) groups. The subsets of cells and cytokine profile were determined by flow cytometry. Maternal blood from MGH group had increase percentage of CD3(+)T cells, and DM-2 group had decrease percentage of CD4(+) T cells. The cord blood from hyperglycemic groups showed lower percentage of CD3(+) T cells expressing CD45RO(+) and higher of CD4(+) T cells and CD4(+) T cells expressing CD45RA(+). In the colostrum, the CD4(+) T cells and CD4(+) T cells expressed CD45RA(+) increase in hyperglycemic groups. The DM2 group exhibited higher IL17 levels in maternal blood. IFN-γ was lower in cord blood from MGH and DMG groups with overweight/obese. Irrespective of the glycemic status, IL6 was higher in colostrum. The results obtained suggest that maternal hyperglycemia modifies the phenotypes of T cells and cytokines profile in maternal, cord blood and colostrum.
