A prospective study among neonates born to mothers with active or past Graves disease.

Objective: The aim of this prospective study was to describe demographic and clinical characteristics of neonates born to mothers with active or past Graves disease and to assess compliance since implementation of a new protocol in our center.

Methods: We prospectively followed up neonates born to mothers with active or past Graves disease in a tertiary hospital in Spain between August 2019 and September 2021 according to our protocol. We reviewed maternal and neonatal history of these neonates, and we followed up newborns at risk of neonatal hyperthyroidism.
