[Two cases of mineralocorticoids deficiency as first endocrine manifestation of APECED syndrome].

The Authors report two cases of APECED syndrome (Auto-immune Polyendocrinopathy-Candidiasis-Ectodermal Dystrophy) revealed by hyponatremia due to isolated mineralocorticoids deficiency. Such cases illustrate the variable endocrine features revealing the syndrome. The mechanisms underlying the auto-immune destruction of the adrenals are discussed.
