Graves' disease in children with Down syndrome

Area of Science:

• Endocrinology
• Genetics
• Pediatrics

Background:

• Hypothyroidism is common in Down syndrome (DS), but Graves' disease (GD) is rare.
• Understanding GD in DS is crucial for appropriate management.

Purpose of the Study:

• To evaluate the clinical features, course, and treatment of GD in children with DS.
• To compare GD presentation and outcomes in children with and without DS.

Main Methods:

• Retrospective data collection from medical records of 161 children with GD.
• Analysis of clinical symptoms, thyroid function tests, antibody levels, and treatment modalities.
• Comparison of patients with DS (n=13) versus those without DS.

Main Results:

• Thirteen children (8%) with DS were diagnosed with GD, with a mean age of 10.6 years.
• Common symptoms included weight loss, irritability, and sweating; none had orbitopathy.
• Treatment with methimazole or carbimazole, often 'block and replace', showed similar outcomes to non-DS patients, with prolonged therapy suggested.

Conclusions:

• The clinical course of Graves' disease in children with Down syndrome is comparable to that in children without DS.
• Prolonged medical therapy appears to be the preferred treatment approach for Graves' disease in this population.
