Autoimmune Polyglandular Syndrome Type 3
Autoimmune polyglandular syndrome (APS) type 3 is an autoimmune condition that affects the body's endocrine glands. The syndrome, which typically affects women during middle age, results from failure of the glands to produce their hormones. This condition is characterized by autoimmune thyroiditis along with another organ-specific autoimmune disease. The other autoimmune diseases may include diabetes mellitus, pernicious anemia, vitiligo, alopecia, myasthenia gravis, and Sjogren's syndrome. The adrenal cortex (the outer layer of the adrenal gland) is not involved. There are three types of autoimmune polyglandular syndrome type 3:
- APS3A - Autoimmune thyroiditis with immune-mediated diabetes mellitus (IMDM)
- APS3B - Autoimmune thyroiditis with pernicious anemia
- APS3C - Autoimmune thyroiditis with vitiligo and/or alopecia and/or other organ-specific autoimmune disease
