Autoimmune polyendocrine syndrome type 1 (APS-1), is a subtype of autoimmune polyendocrine syndrome (autoimmune polyglandular syndrome) in which multiple endocrine glands dysfunction as a result of autoimmunity. It is a genetic disorder inherited in autosomal recessive fashion due to a defect in the AIRE gene (autoimmune regulator), which is located on chromosome 21 and normally confers immune tolerance.[4][6][7]

Signs and symptoms[]

Autoimmune polyendocrine syndrome type 1 symptoms and signs include the following:[3]

Additional manifestations include

Genetics[]

Chr 21

Autoimmune polyendocrine syndrome type 1 is inherited in an autosomal recessive manner. It is due to a defect in the AIRE gene (which encodes a protein called autoimmune regulator) mapped to the 21q22.3 chromosome location, hence chromosome 21.[4][6][8]


Pathophysiology[]

In autoimmune polyendocrine syndrome type 1 mechanism one finds that the maintenance of immunological tolerance plays a role.[9] Furthermore, upon looking at the AIRE gene, one finds at least 90 mutations in the gene, in those affected with this condition.[medical citation needed]

Autoimmune polyendocrine syndrome type 1 mechanism also indicates that affected individuals autoantibodies have considerable reactions with both interferon omega and interferon alpha.[1]

Diagnosis[]

Endoscope

In terms of diagnosis for this condition, the following methods/tests are available:[1]

  • Endoscopic
  • CT scan
  • Serum endocrine autoantibody screen
  • Histologic test

Treatment[]

Autoimmune polyendocrine syndrome type 1 treatment is based on the symptoms that are presented by the affected individual, additionally there is:[5]

  • Hormone replacement
  • Systemic antifungal treatment
  • Immunosuppressive treatment
