Neonatal Graves' is uncommon, but a potentially fatal condition caused by transplacental transfer of thyroid stimulating immunoglobulin (TSI). It is seen in 1%-5% of infants born to a mother with Graves' disease. Here, we report a unique case of transient neonatal thyrotoxicosis with positive TSI in a premature neonate born to the mother with primary hypothyroidism. A short course of antithyroid drug treatment leads to significant clinical and biochemical improvement followed by complete recovery.

Maternal Graves' disease (GD) poses a significant risk to neonatal thyroid function due to the transplacental transfer of thyrotropin receptor antibodies (TRAbs). This systematic review aims to assess the impact of maternal GD on neonatal thyroid outcomes and identify key maternal factors influencing these outcomes. A comprehensive literature search was conducted across PubMed, Scopus, and Cochrane, resulting in the inclusion of 18 studies published from 2014 to 2024.

Fetal and neonatal thyrotoxicosis occurs in up to 5% of pregnancies in mothers with Graves' disease (GD). This condition is caused by stimulating antibodies against the thyrotropin receptor (TRAbs) that cross the placenta and may stimulate the fetal thyroid, typically in the second half of pregnancy. GD is often treated with radioiodine, resulting in hypothyroidism in most patients, but TRAbs can persist for several years.

Intergenerational and transgenerational epigenetic effects resulting from conditions in previous generations can contribute to environmental adaptation as well as disease susceptibility. Previous studies in rodent and human models have shown that abnormal developmental exposure to thyroid hormone affects endocrine function and thyroid hormone sensitivity in later generations. Since the imprinted type 3 deiodinase gene () regulates sensitivity to thyroid hormones, we hypothesize its epigenetic regulation is altered in descendants of thyroid hormone overexposed individuals.

Preconception evaluation of couples wishing to conceive is an important step toward a healthy pregnancy and it is especially important in people with a chronic condition or at genetic risk. The most common endocrine disorders in women at reproductive age are those involving the thyroid gland and it is well recognized that hyperthyroidism (HT), over-function of the thyroid gland, is associated with risks of maternal, fetal, and neonatal complications. The aim of this paper is to review the latest evidence regarding the components of preconception counseling in women with HT that contemplate a pregnancy.

Objectives: Maternal antibodies in cases of chronic autoimmune thyroiditis may be transferred to the baby via the transplacental route, leading to transient hyperthyroidism or hypothyroidism. The development of hyperthyroidism in one sibling and hypothyroidism in the other, however, is an extremely rare condition. We present two siblings, one with transient neonatal hyperthyroidism and the other with transient neonatal hypothyroidism, born to a euthyroid mother who was being treated for Hashimoto's thyroiditis.
