Treatment of Subclinical Hypothyroidism or Hypothyroxinemia in Pregnancy [PDF]

open access: yesNew England Journal of Medicine, 2017
(Abstracted from N Engl J Med 2017;376:815–825) Subclinical hypothyroidism (SCH) during pregnancy has been associated with impaired fetal neuropsychological development. Several organizations recommend treatment of subclinical thyroid dysfunction, although the Controlled Antenatal Thyroid Screening study found mothers who were treated with ...

Hypothyroxinemia of Prematurity: Cause, Diagnosis and Management

open access: yesExpert Review of Endocrinology and Metabolism, 2008
Infants born at extreme prematurity are at a high risk of developmental disability. A major risk factor for disability is having a low level of thyroid hormone, described as hypothyroxinemia, which is recognized to be a frequent phenomenon in these infants.

Hypothyroxinemia: A Subclinical Condition Affecting Neurodevelopment

open access: yesExpert Review of Endocrinology and Metabolism, 2010
Hypothyroxinemia with low levels of circulating free thyroxine and normal levels of thyrotropin, which is usually caused by iodine deficiency, may affect pregnant women even in apparently iodine-sufficient areas, and it is debated whether it increases the risk of neurodevelopmental abnormalities in children born to them.

Gestational Hypothyroxinemia Affects Glutamatergic Synaptic Protein Distribution and Neuronal Plasticity Through Neuron-Astrocyte Interplay

open access: yesMolecular Neurobiology, 2016
International audienceGestational hypothyroxinemia, characterized by low levels of maternal thyroxine (T4) during gestation, is closely associated with cognitive impairment in offspring.

Hypothyroxinemia in Cardiac Arrest

Survey of Anesthesiology, 1987
Thyroid function was evaluated in cardiac arrest (CA), a condition associated with marked activation of the pituitary-adrenal axis. Blood samples were obtained in 24 patients immediately after diagnosis of CA and again ten minutes later. Samples were also obtained from 22 patients admitted consecutively to the intensive care unit (ICU).

Neonatal hypothyroxinemia

The Indian Journal of Pediatrics, 1988
Serum thyroxine (T4) and thyroid stimulating hormone (TSH) were estimated in 25 well term and 30 well preterm neonates in blood samples collected from cord blood and subsequently at 24 hours and 72 hours of age. Cord blood serum T4 concentration was higher in term than preterm babies. Reverse pattern was observed for serum TSH concentration. Both serum

Hypothyroxinemia and Prematurity

NeoReviews, 2008
The growing fetus relies on adequate thyroid hormone concentrations for normal development, which is dependent on maternal transplacental thyroid hormone passage and the appropriate development of the fetal hypothalamic-pituitary-thyroid axis. Untreated congenital hypothyroidism can result in severe neurodevelopmental disabilities, including mental ...

Transient Hypothyroxinemia of Prematurity

NeoReviews, 2016
Thyroid hormones play an important role in central nervous system development, starting from the exclusive maternal contribution in the first trimester and transitioning to a fully independent servo-control system at term birth. Extremely preterm delivery before 28 weeks’ gestational age disrupts this normal transition and reveals the challenge of ...

Transient Hypothyroxinemia in Preterm Infants: The Role of Cord Sera Thyroid Hormone Levels Adjusted for Prenatal and Intrapartum Factors.

open access: yesJournal of Clinical Endocrinology and Metabolism, 2005
Context: Transient hypothyroxinemia is common in infants less than 30 wk gestation and is associated with neurodevelopmental deficits; it has no consensus definition.
