OBJECTIVE: The present study evaluated the cells and cytokine of maternal blood, cord blood and colostrum of diabetic mothers. METHODS: 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. RESULTS: 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. CONCLUSION: The results obtained suggest that maternal hyperglycemia modifies the phenotypes of T cells and cytokines profile in maternal, cord blood and colostrum.
