Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Thyroid hormones are the cornerstones of a complex system that plays an important role in the growth and development of children, especially in the development of the nervous system and brain. Therefore, even minimal disruptions of this system can cause permanent damage.

Thyroid dysfunction is a common problem in pre-term infants. Hypothyroxinemia of prematurity within the first month of life may represent important prognostic information about morbidity and mortality. Thyroid hormone synthesis may be disrupted in co-morbid conditions . worsening the metabolism of premature infants and causing higher hormone levels compared to healthy infants.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The most common thyroid function disorder in premature infants is physiological hypothyroxinemia, followed by hypothyroidism of non-thyroidal causes. In pre-maturity, several factors can inhibit the conversion of peripheral T4 to T3, including hypoxemia, acidosis, infections, hypoglycemia, hypocalcemia and malnutrition . Some rare conditions include transient secondary/tertiary hypothyroidism, transient primary hypothyroidism and permanent primary hypothyroidism.

Thyroid dysfunction has been reported to be more common in infants with low birth weight due to inadequate intrauterine nutrition, hypoxia, and acidosis.In addition, a meta-analysis found that birth weight and gestation week age closely related to thyroid function tests. Plasma T4, FT4, T3, rT3, (thyroid stimulating hormone), and (thyroxin binding globulin) concentrations during the first 8 weeks after birth in infants of 28-30 weeks gestation and in infants of \<28 weeks gestation.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Healthy preterm infants

Thyroid function in Preterm infants not needing hospital admission will be estimated at day 3 and day 10 of life.

No interventions assigned to this group

Sick preterm infants

Thyroid function in sick preterm infants admitted to NICU will be estimated at day 3 and day 10 of life .

No interventions assigned to this group
