Early screening for Congenital Hypothyroidism (CH) in Brazil found a prevalence of 1:2500. This highlights the need for widespread newborn screening programs to ensure timely treatment and improve outcomes for affected infants.

Area of Science:

  • Endocrinology
  • Neonatal screening
  • Public health

Context:

  • Congenital Hypothyroidism (CH) is a common endocrine disorder in newborns.
  • Early detection and treatment are crucial to prevent intellectual disability and developmental delays.
  • Screening programs vary globally, necessitating regional data collection.

Purpose:

  • To report the initial findings of a Congenital Hypothyroidism screening program in Santa Catarina, Brazil.
  • To determine the prevalence of CH in the studied population.
  • To evaluate the effectiveness of the screening protocol.

Summary:

  • A screening program analyzed 82,709 infants for Congenital Hypothyroidism (CH) using serum Thyroid Stimulating Hormone (TSH) measurements.
  • 304 infants had abnormal TSH levels, and 34 were diagnosed with CH, yielding a prevalence of 1:2500.

  • The mean age for initiating treatment was 45 days, with efforts underway to expedite this process.

    • Impact:

    • The study identified a higher CH prevalence in Brazil compared to other nations, possibly due to transient cases.
    • Non-specific clinical manifestations underscore the critical role of universal newborn screening.
    • Findings support the expansion and refinement of neonatal screening programs for CH.
