Diagnosed congenital hypothyroidism with missing follow-up: is it time for a national registry?

Area of Science:

• Pediatric Endocrinology
• Neonatal Screening
• Metabolic Disorders

Background:

• Congenital hypothyroidism (CH) is a treatable cause of mental retardation.
• Neonatal screening programs aim to detect CH early for timely intervention.

Observation:

• A 17-year-old male diagnosed with CH via newborn screening had an ectopic thyroid gland.
• Treatment was initially discontinued by the family, with follow-up delayed until age 11.
• Despite re-initiation of thyroxine and normalized thyroid function, the patient experienced short stature and impaired IQ.

Findings:

• Delayed and inconsistent follow-up care significantly impacted the long-term neurodevelopmental and physical outcomes in a patient with congenital hypothyroidism.
• Even with early diagnosis, lapses in patient adherence and monitoring systems can lead to irreversible complications.

Implications:

• Highlights the critical need for robust patient follow-up systems in managing congenital hypothyroidism.
• Suggests the implementation of a patient registry for congenital hypothyroidism to enhance care monitoring and evaluate screening program efficacy.
• Emphasizes the importance of patient and family education regarding lifelong management of CH.
