Graves' disease associated with juvenile idiopathic arthritis

Area of Science:

• Pediatric Rheumatology
• Endocrinology
• Ophthalmology

Background:

• Graves' disease (GD) is an autoimmune disorder affecting the thyroid gland.
• Antithyroid drugs like propylthiouracil are common treatments for GD.
• Autoimmune conditions can present with complex, multi-systemic manifestations.

Observation:

• A 10-year-old girl with diagnosed Graves' disease was treated with propylthiouracil.
• The patient subsequently developed symptoms of uveitis and polyarticular arthritis.
• Her mother had a history of Graves' disease and discoid lupus erythematosus.

Findings:

• The co-occurrence of uveitis and polyarticular arthritis in a child with Graves' disease on propylthiouracil is a rare presentation.
• This clinical scenario suggests a potential link between autoimmune thyroid disease, its treatment, and the development of inflammatory arthritis and ocular inflammation.
• The patient's family history of autoimmune disorders further supports a potential genetic predisposition.

Implications:

• This case underscores the need for a broad differential diagnosis in pediatric patients with autoimmune thyroid disease experiencing new inflammatory symptoms.
• Clinicians should consider inflammatory arthritis and uveitis in the differential diagnosis for children with Graves' disease on antithyroid medications.
• Further research may elucidate the specific mechanisms linking antithyroid drugs, autoimmune thyroid disease, and inflammatory conditions.
