TreatmentDepends on type

Autoimmune polyendocrine syndromes (APSs), also called polyglandular autoimmune syndromes (PGASs)[5] or polyendocrine autoimmune syndromes (PASs), are a heterogeneous group[6] 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, and there are a number of other diseases which involve endocrine autoimmunity.[4][7][8]

Types

APS1- a) Hypomineralization b) severe enamel hypoplasia c)enamel hypoplasia

Cause

Each "type" of this condition has a different genetic cause. IPEX syndrome is inherited in males by an X-linked recessive process. The FOXP3 gene, whose cytogenetic location is Xp11.23, is involved in the mechanism of the IPEX condition.[13][3]

Diagnosis

CT scan

Diagnosis for type 1 of this condition for example, sees that the following methods/tests are available:[4]

Differential diagnosis

For this condition, differential diagnosis sees that the following should be considered:[14]

Management

Ketoconazole

Immunosuppressive therapy may be used in type I of this condition.[15] Ketoconazole can also be used for type I under certain conditions.[4]

The component diseases are managed as usual; the challenge is to detect the possibility of any of the syndromes and to anticipate other manifestations. For example, in a person with known type 2 autoimmune polyendocrine syndrome but no features of Addison's disease, regular screening for antibodies against 21-hydroxylase may prompt early intervention and hydrocortisone replacement to prevent characteristic crises[medical citation needed]
