[Schmidt's syndrome. Interrelationships between thyroid hormones and cortisol (author's transl)].

An hypothyroidism is discovered. Secondary, a primary adrenal insufficiency is proved. Therefore, we can affirm the Schmidt's syndrome. The anti-adrenal and anti-thyroid antibodies are positive; when the glucocorticoid treatment is begun, the dose of thyroxine treatment must be decreased. That point allows us to discuss the interrelationships between thyroid and adrenals.
