Abstract
Autoimmune polyglandular syndrome, type 1 (APS-1) is a rare syndrome. Here we present a case report of a 24-year-old female patient who complained of progressive weakness. While autoimmune hepatitis was diagnosed, no improvement of biochemical parameters was obtained after immunosuppressive treatment. Hypoparathyroidism and adrenocortical failure were identified. Her health status clearly improved once proper control of the calcium-phosphate metabolism was obtained and after the administration of substitution hydrocortisone doses, leading to full normalization of biochemical liver tests. The reported case illustrates a rare form of APS-1 failure, in which the diagnosed autoimmune hepatitis was only the first symptom.
