Abstract

Subclinical hypothyroidism is characterized by elevated thyroid stimulating hormone (TSH) levels with normal free thyroxine (fT4) levels. The aim of this study was to compare obstetric and neonatal outcomes in pregnant women with and without treatment for subclinical hypothyroidism. In this study, maternal and perinatal outcomes were evaluated in a total of 270 pregnant women who were diagnosed with subclinical hypothyroidism as a result of screening performed in three trimesters of pregnancy between 2015 and 2020 and followed up in our clinic, 149 of whom received levothyroxine treatment and 121 of whom did not receive treatment. Further, different cutoff values for TSH were compared. The rates of neonatal intensive care unit (NICU) requirement were not different according to the levothyroxine use status of the patients (p=0.73, p>0.05). Miscarriage rates did not differ according to levothyroxine use (p=0,87, p>0,05). TSH, T4 and antithyroid peroxidase levels did not differ according to the maternal use of levothyroxine (p>0,05). Birth weight, gestational week at birth, 1- and 5-minute APGAR scores, neonatal TSH and T4 levels did not differ according to the maternal use of levothyroxine (p>0,05). Among the adverse maternal and perinatal outcomes, the need for NICU admission and the rates of placental abruption, fetal distress, preterm premature rupture of membranes, preeclampsia, preterm labor, and small for gestational age were not significantly different among the TSH cutoff groups (p>0,05). The rate of premature rupture of membranes was higher in the group with TSH levels ≥2.5 mIU/L (p=0.04). Choosing 2.5 mIU/L as the cutoff value for TSH levels allows early diagnosis of subclinical hypothyroidism with a higher rate in pregnant Turkish women and proactive therapeutic management. Our study provides limited evidence for the success of levothyroxine therapy for adverse obstetric and neonatal outcomes.
