In medicine, autoimmune polyendocrine syndromes (APSs), also called autoimmune polyglandular syndromes (APSs), polyglandular autoimmune syndromes (PGASs), or polyendocrine autoimmune syndromes, are a heterogeneous group of rare diseases characterized by autoimmune activity against more than one endocrine organ, although non-endocrine organs can be affected.
There are three types of APS or (in terms that mean the same thing) three APSs, and there are a number of other diseases which have endocrine autoimmunity as one of their features.
Other diseases featuring polycrine autoimmunity:
In principle, the component diseases are managed as usual. The challenge is to detect the possibility of any of the above syndromes, and to anticipate other manifestations. For example, in a patient with known Type 2 autoimmune polyendocrine syndrome but no features of Addison's disease, regular screening for antibodies against 21-hydroxylase (a feature of Addison's) may prompt early intervention and hydrocortisone replacement to prevent characteristic crises.
