Children with Down syndrome often have abnormal thyroid function, including lower T4 and higher TSH levels, increasing their risk for hypothyroidism. Regular thyroid screening is recommended for early detection and improved quality of life.

Area of Science:

  • Endocrinology
  • Genetics
  • Pediatrics

Background:

  • Down syndrome is associated with a higher prevalence of thyroid dysfunction compared to the general population.
  • Thyroid hormone imbalances can significantly impact development and overall health in individuals with Down syndrome.

Purpose of the Study:

  • To investigate thyroid function in a cohort of patients with Down syndrome.
  • To identify the prevalence of thyroid abnormalities, including hypothyroidism, in this population.
  • To assess the impact of age on thyroid hormone levels in individuals with Down syndrome.

Main Methods:

  • Thyroid function was assessed in 181 patients with Down syndrome and compared to 163 controls.
  • Measurements included thyroxine (T4), free thyroxine (FT4), triiodothyronine (T3), free triiodothyronine (FT3), thyroid-stimulating hormone (TSH), and thyroxine-binding globulin (TBG).

  • Data were analyzed across different age groups and compared between two time points (1985 and 1988).
  • Main Results:

    • Patients with Down syndrome exhibited significantly lower T4 and FT4 levels and significantly higher T3 and TSH levels compared to controls.
    • 16% of patients with Down syndrome showed evidence of hypothyroidism (uncompensated or compensated).
    • Thyroid hormone levels (T4, FT4, T3, FT3, TBG) declined with advancing age.

    Conclusions:

    • Thyroid dysfunction is common in individuals with Down syndrome, necessitating routine thyroid function monitoring.
    • Early detection through periodic testing, especially in older individuals, allows for timely intervention.
    • Appropriate management of thyroid disorders can enhance the quality of life for patients with Down syndrome.
