RESUMO
To evaluate the impact that hypothyroidism may have on the course of pregnancy and on neonatal outcome. This cross-sectional study consisting of 160 pregnant women (60 with hypothyroidism and 100 as control) who had been hospitalized at the Obstetrics and Gynecology of the University of Siena. The obstetric visit, the collection of anamnestic data and serum concentrations of TSH, FT4 and AbTPO were performed for each woman. Stratification of the population into two groups based on the BMI showed that there is an average difference of -0.88 before pregnancy BMI between healthy women and hypothyroid women. Moreover, with regard to the obstetric history, 8.7 times higher risk of abortion was found in hypothyroid women. About the current pregnancy in hypothyroid women, slight fetal growth delay, increased risk of premature rupture of membranes (PROM), and a higher risk of developing hypertension and gestational diabetes had been found. The importance of a more detailed anamnesis should be evaluated with greater attention at the beginning of pregnancy. This, in order to avoid the risks related to a hypothyroidism condition during pregnancy and to establish an early therapeutic treatment appropriate to the metabolic demands of each patient.
