Maternal Third-Trimester TRAb Is Associated with Neonatal Thyroid Dysfunction and 24-Month Offspring Neurodevelopment: A Bidirectional Cohort Study

ThyroidPublished Bidirectional cohort study

Authors' conclusion

Higher maternal third-trimester TRAb levels were associated with both neonatal thyroid dysfunction and abnormal neurodevelopmental screening results at 24 months in offspring of mothers with GD. This association with neurodevelopmental screening results may not be explained primarily by neonatal thyroid function alone.

Study context

Population
Pregnant women with Graves' disease (GD) and their offspring delivered between January 1, 2019, and December 31, 2023
Participants
159 neonates
Exposure
Maternal GD-related thyroid factors (TSH, FT4, TRAb, antithyroid drug exposure) and neonatal thyroid function/neurodevelopment
Outcome
Associations of maternal third-trimester TRAb with neonatal thyroid dysfunction and abnormal neurodevelopmental screening at 24 months

As reported in the abstract

Higher maternal third-trimester TRAbOdds ratio (CI)P value
Neonatal thyroid dysfunction; independently associated
1.59(1.29–1.97)
P < 0.001
Abnormal neurodevelopmental screening at 24 months; independently associated
1.15(1.04–1.27)
P = 0.005
Neonatal thyroid dysfunction

Observational data: associations, not effects.

Further findings

Exploratory mediation analysis did not support a significant mediating role of neonatal TSH
