Modeling Encephalopathy of Prematurity Using Prenatal Hypoxia-ischemia with Intra-amniotic Lipopolysaccharide in Rats
Published on: November 20, 2015
Insights
Sick newborns, particularly premature infants, can experience temporary primary hypothyroidism. Most infants recovered fully within two months of treatment cessation, suggesting iodine deficiency as a potential cause.
Area of Science:
- Neonatal Medicine
- Endocrinology
- Pediatrics
Background:
- Transient primary hypothyroidism is observed in sick neonates.
- Premature infants are particularly susceptible to this condition.
Purpose of the Study:
- To investigate the occurrence and characteristics of transient primary hypothyroidism in sick neonates.
- To explore potential etiologic factors, including iodine deficiency, in the pathogenesis of this condition.
Main Methods:
- Clinical observation and biochemical assessment of twelve sick neonates with transient primary hypothyroidism.
- Follow-up evaluation of patients after cessation of treatment to assess recovery.
Main Results:
- Ten out of twelve affected neonates were premature.
- All followed neonates achieved clinical and biochemical euthyroid status two months after treatment cessation.
Conclusions:
- Transient primary hypothyroidism is a reversible condition in sick neonates.
- Iodine deficiency is a likely precipitating factor in the development of transient hypothyroidism among premature infants.
Abstract:
Twelve sick neonates, ten of whom were prematures, were found to have transient primary hypothyroidism. Two months after cessation of treatment all those followed were found to be clinically and biochemically euthyroid. The possible etiologic factors in the pathogenesis of transient hypothyroidism of the sick prematures are discussed. Iodine deficiency is probably an important precipitating cause.

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...
Functions of Thyroid Hormones
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
