Autoimmune Polyendocrinopathy Syndrome Type 1 (APS1) can manifest with chronic mucocutaneous candidiasis and hypoparathyroidism. Genetic analysis confirmed AIRE gene mutations in a child and fetus, leading to pregnancy termination.
Area of Science:
- Endocrinology
- Genetics
- Immunology
Background:
- Autoimmune Polyendocrinopathy Syndrome Type 1 (APS1) is an autoimmune disorder.
- APS1 is defined by at least two of three key features: chronic mucocutaneous candidiasis (CMC), Addison's disease, and hypoparathyroidism.
Observation:
- A case report details a 1.5-year-old girl presenting with recurrent oral thrush and seizures.
- Medical evaluation revealed severe hypocalcemia with low parathormone levels, indicating hypoparathyroidism.
- The patient also had a history of oral candidiasis.
Findings:
- The clinical presentation strongly suggested Autoimmune Polyendocrinopathy Syndrome Type 1 (APS1).
- Genetic analysis of the index child and fetus (via chorionic villus sampling) confirmed mutations in the AIRE gene, causative for APS1.
- The parents chose medical termination of the pregnancy after genetic counseling.
Implications:
- Recurrent oral thrush in children warrants consideration for conditions beyond immunodeficiency, including APS1.
- Early diagnosis and genetic testing are crucial for managing APS1 and for family planning.
- This case highlights the importance of comprehensive evaluation for rare autoimmune disorders in pediatric patients.
