Abstract
- Background: Higher levels of thyroid autoantibodies in follicular fluid (FF) of thyroid autoimmunity (TAI) positive women are strongly correlated with serum levels and may have effect on the post-implantation embryo development. Literature highlights that levothyroxine (LT4) treatment may attenuate the risk of adverse pregnancy outcomes. The aim of the study was to estimate the pregnancy and newborn outcomes in women with FF thyroid autoantibodies undergoing assisted reproductive technology (A RT). Methods: The study population included 24 women with confirmed clinical pregnancy, 8 TAI positive and 16 TAI negative women. LT4 supplementation was applied in 20.8% patients, TAI positive. Results: Pregnancy outcomes were: twin pregnancy rate 4 1 .7 % , early miscarriage rate 8.3% , late miscarriage rate 4.2% , preterm birth rate 16.7% , term birth rate 70.8% , live birth rate 96.0% . There was significant difference in serum and in FF TgAbs (p< 0.001)betw een the groups according to TAI, while serum fT 3 was lower in the group with TAI (p = 0 .0 4 7 ). Serum P 4 was higher in LT4 treated group (p = 0 .0 0 5 ), with TAI, and newborns in this group had higher birth weight (p = 0.001) and height (p = 0 .0 0 8 ). Maternal complications occurred in 23.8% of patients. No congenital malformations in newborns were noted. Conclusions: Thyroid autoantibodies present in FF may have an effect on the post-implantation embryo development, but have no effect on further course of pregnancy. The special benefit of LT4 treatment for successful A R T outcome was demonstrated for newborn anthropometric parameters.
