APECED2: Characterization of the Fungal Origins in the Autoimmune Polyendocrinopathy of Type 1 Compared With the Autoimmune Polyendocrinopathies of Type 2
Study Details
Study Description
Brief Summary
Autoimmune polyendocrinopathy candidiasis ectodermal dystrophy (APECED) is an autosomal recessive disease caused by mutations in the autoimmune regulator (AIRE) gene, characterized by the clinical triad of chronic mucocutaneous candidiasis (CMC), hypoparathyroidism, and adrenal insufficiency. CMC can be complicated by systemic candidiasis or oral squamous cell carcinomas (SCCs) and may lead to death. The role of chronic Candida infection in the etiopathogenesis of oral SCC is unclear. Long term use of fluconazole lead to emergence of C. albicans strains with azoles decreased susceptibility. CMC is associated with an impaired Th17 cell response, however, it remains unclear whether decreased serum IL-17 and IL-22 levels are related to a defect in cytokine production or to neutralizing autoantibodies resulting from mutations in the AIRE gene

Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Group 1 APS 1 Patients with a APS type 1 whose molecular diagnosis (mutation of the AIRE gene) has been established in the diagnosis of the disease, regardless of their mycological status (history of mycosis) or the presence of antifungal treatment. |
|
| Group 2 APS2 Patients with APS type 2: - with adrenal insufficiency for 50% of them. - a delay of two weeks after stopping antifungal or antibiotic treatment in patients is to be respected. |
Outcome Measures
Primary Outcome Measures
- the frequency of appearance of Candida yeast strains [Baseline: one session]
the frequency of appearance of Candida yeast strains found in mycological samples from both urinary and oral patients.
