Abstract:
Objective:To explore the relationship between the positive thyroid peroxidase antibody (TPOAb) in early pregnancy and the adverse maternal and infant outcomes.Methods:A retrospective analysis was conducted on the clinical data of 168 TPOAb positive pregnant women who underwent early prenatal testing in Family Planning Endocrinology Department of Shanxi Children’s Hospital from Jun. 2020 to Dec. 2022. They were divided into group A (104 cases with normal thyroid function and TPOAb positive) and group B (64 cases with hypothyroidism and TPOAb positive) based on their thyroid function. Another 150 pregnant women with negative TPOAb during early prenatal testing during the same period were selected as the control group. Follow up was from the first prenatal examination to 6 weeks after delivery, the adverse pregnancy outcomes of three groups of pregnant women and fetuses were recorded, and chi square test for inter group comparison was used.Results:There were statistically significant differences in the incidence of adverse outcomes such as diabetes, premature rupture of membranes and cesarean section among the three groups ( P values were 0.028, 0.003 and 0.006, respectively). The incidence of premature rupture of membranes in group A was significantly higher than that in the control group ( P=0.003). The incidences of pregnancy diabetes, premature rupture of membranes and cesarean section in group B were significantly higher than those of the control group ( P=0.008, 0.003, 0.001, respectively). The incidence of cesarean section in group B was significantly higher than group A ( P=0.0461). There was no statistically significant difference in the incidence of adverse outcomes such as gestational hypertension, preeclampsia, abnormal amniotic fluid, placental abruption, miscarriage, difficult labor, and stillbirth among the three groups of pregnant women ( P values of 0.433, 0.137, 0.231, 0.825, 0.138, 0.356, and 0.933, respectively). The incidence rates of premature birth, intrauterine distress, fetal growth restriction, and pathological jaundice were compared among the three groups of fetuses, and the differences were statistically significant ( P<0.001, 0.008, 0.038, respectively). The incidence of intrauterine distress and pathological jaundice in group A was significantly higher than control group ( P<0.001, 0.028, respectively), while the incidence of premature birth, intrauterine distress, fetal growth restriction, and pathological jaundice in group B was significantly higher than the control group ( P<0.010, <0.000, 0.001, 0.014, respectively) . Conclusions:TPOAb positive in early pregnancy can increase the incidence of adverse maternal and infant outcomes such as premature rupture of membranes, preterm delivery, intrauterine distress, pathological jaundice, etc. Early screening of thyroid function and TPOAb and intervention will help reduce adverse maternal and infant outcomes.
