Gastrointestinal manifestations in autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) patient: major effect on treatment and prognosis.

SUMMARY

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare autosomal recessive inherited syndrome caused by mutations in autoimmune regulator (AIRE) gene. The three clinical components of this syndrome are mucocutaneous candidiasis, hypoparathyroidism, and primary adrenal insufficiency. In addition to these frequent symptoms, many other components have been reported including gastrointestinal manifestations.We report a case of a 17-year-old Caucasian female patient diagnosed with APECED who presented with acute abdominal pain. Her medical history revealed chronic digestive discomfort without bowel movement disorders. The patient needed a significant increase in doses of calcium supplementation and hydrocortisone which appeared to be partially inefficient. Investigation with esophagogastroduodenoscopy and biopsy showed autoimmune atrophic gastritis. The patient eventually needed increasing doses of treatment received in order to achieve desired clinical and biological therapeutic goals.

LEARNING POINTS

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare autosomal recessive inherited syndrome caused by mutations in the autoimmune regulator (AIRE) gene. The three clinical components of this syndrome that appear in early childhood are mucocutaneous candidiasis, hypoparathyroidism, and primary adrenal insufficiency. In addition to these frequent symptoms, many other components have been reported including gastrointestinal manifestations like atrophic gastritis. They can be caused by many abnormalities including atrophic gastritis and the modification of intestinal biofilm and microbiota. Early diagnosis and treatment of gastrointestinal manifestations associated with APECED prevent multiple life-threatening consequences like acute adrenal crisis and severe symptomatic hypocalcemia.
