Polyglandular autoimmune syndrome, type 2

We have described two patients with Addison's disease and associated endocrinopathies, a condition termed polyglandular autoimmune (PGA) syndrome, type 2. One of our patients also had autoimmune hypothyroid disease, and the other had premature gonadal failure and Hashimoto's thyroiditis. This syndrome shows that glandular disorders tend to occur together. It has been suggested that an HLA-associated genetic predisposition coupled with environmental factors triggers an autoimmune process resulting in glandular hypofunction or hyperfunction. We stress the necessity for evaluation of every individual with idiopathic Addison's disease for associated endocrinopathies.
