Autoimmune endocrinopathies belong to so-called organ specific autoimmune diseases. These diseases combine very often and from the polyglandular autoimmune endocrine syndrome (PAES), where autoantibodies either destroy or stimulate individual endocrine glands or hormone receptors in target tissues. Thus a wide range of combinations of hypofunctional or hyperfunctional clinical syndromes develops. PAES is a good natural model of endocrine polyautoaggressiveness. In its development the following aetiopathogenetic factors participate: 1. Hereditary familial disposition, expressed e.g. by certain inherited HHS genes (e.g. A1, B8, DR 3, 4). 2. Aberrant expression of these DR genes on endocrine organs due to bacterial or viral infections, pregnancy, stimulation of the thyroid gland by TSH or immunoglobulins (TSIg). 3. Antigenic mimicri and the presentation of autoantigens to immunocompetent cells. 4. Impaired immunoregulation--antigen specific insufficiency of suppressor T lymphocytes. 5. Local and general amplification reaction to an autoimmune process. 6. The development and autoreproduction of organ specific autoimmune endocrine disease and its development into the final stage of endocrine disease where autoantibodies may disappear. The diagnosis of PAES in clinical practice is difficult. Common immunological tests are not very conclusive. To assess a polyglandular affection we found useful the multiaxial synchronous test where stimulation of several hypothalamic releasing hormones combined with a hypoglycaemic stimulus is used. Autoimmune lymphocytic hypophysitis is part of PAES. In clinical practice this syndrome is therefore frequently incorrectly diagnosed and then incorrectly treated.
