Polyglandular autoimmune syndrome: current concepts.
The polyglandular autoimmune syndrome (PGAS) is characterized by the association of two or more endocrine disorders that are mediated by autoimmune mechanisms and usually lead to a hypofunctional state. In this review we classify the various types of PGAS and discuss their clinical features and the pathophysiologic autoimmune mechanisms that are thought to play an important role. Circulating organ- and cell-specific autoantibodies are frequently detected in patients with the syndrome and may be a marker of future organ failure. PGAS should be considered in patients with one or more of the disorders constituting the syndrome; this should facilitate early diagnosis and perhaps even prevention of other components of the disease. Early recognition and replacement therapy can be life-saving, particularly when there is adrenal or thyroid insufficiency.
