ABSTRACT
OBJECTIVES:
Growing data suggest a role of Treg cells in placentation. The aim of the study was to evaluate Treg cells (FOXP3-positive cells) placental bed infiltration in patients with placenta accrete syndrome (PAS) and patients who experienced placental abruption. MATERIAL ANDMETHODS:
The study group included 13 patients with PAS and the control group consisted of 66 women who had caesarean (CD) delivery of whom, 44 patients with elective caesarean (EC) delivery, and 22 patients with urgent caesarean (UC) delivery due to placental abruption. FOXP3 cell infiltration was assessed by means of immunohistochemistry in placental chorionic villous (CV) and in the decidua (D) and cumulatively in the placental bed (PB).RESULTS:
We observed significant difference in the degree of FOXP3-positive cell CV infiltration between studied groups (p = 0.04). FOXP3-positive cells were the most commonly observed in PAS patients, while, they were the least frequently presented in patients after UC. The immunoreactivity for FOXP3-positive cells in CV were as follows PAS 5 (38%), urgent CS 1 (5%) and elective CS 8 (18%) subjects. We found no difference in the presence of FOXP3-positive cells in the D (p = 0.35) and in the PB (p = 0.23) of analyzed groups. FOXP3-cell infiltration was not related with patient age, BMI, gestational age and neonatal birth weight.CONCLUSIONS:
Our study provides further evidence that abnormal invasive placentation is an associated disturbance of the maternal immune response. Accordingly, we have theorized that alteration of the FOXP3-positive Treg cell infiltration into the placental bed allows trophoblast cell invasion.Palavras-chave
