Autoimmune polyendocrine syndrome

Autoimmune polyendocrine syndromes (APSs), also called autoimmune polyglandular syndromes (APSs), polyglandular autoimmune syndromes (PGASs),[2] or polyendocrine autoimmune syndromes, are a heterogeneous group[3] 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.[1][4][5]

TypesEdit

CauseEdit

Each "type" of this condition has a different cause, in terms of IPEX syndrome is inherited in males by an x-linked recessive process. FOXP3 gene, whose cytogenetic location is Xp11.23, is involved in the mechanism of the IPEX condition.[10][11]

DiagnosisEdit

 
CT scan

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

Differential diagnosisEdit

For this condition, differential diagnosis sees that the following should be considered:[12]

ManagementEdit

 
Ketoconazole

Immunosuppressive therapy may be used in type I of this condition,[13] ketoconazole can be used for autoimmune polyendocrine syndrome type I under certain conditions[1]

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]
