Graves' disease in a Down's syndrome patient

Area of Science:

• Pediatric Endocrinology
• Genetics and Genetic Diseases
• Autoimmune Disorders

Background:

• Down syndrome (DS) is associated with a high prevalence of thyroid dysfunction, primarily hypothyroidism.
• Hyperthyroidism in children with DS is uncommon, with autoimmune etiology suspected.
• Graves' disease, a common cause of hyperthyroidism, is rarely reported in pediatric DS patients.

Observation:

• A pediatric patient with Down syndrome presented with symptoms suggestive of hyperthyroidism.
• The patient was diagnosed with Graves' disease, an autoimmune condition affecting the thyroid.
• This specific association in a child under eight years old is notably rare.

Findings:

• The patient with Down syndrome and Graves' disease showed a positive response to standard antithyroid drug therapy.
• Early diagnosis and management of hyperthyroidism in this population are crucial.
• The case underscores the importance of considering autoimmune thyroid conditions in children with DS.

Implications:

• This case contributes to the limited literature on Graves' disease in young children with Down syndrome.
• Highlights the need for vigilant thyroid monitoring in children with DS, including for hyperthyroidism.
• Emphasizes that antithyroid drugs can be an effective treatment modality for Graves' disease in this specific pediatric population.
