Autoimmune polyendocrine syndrome type 2, a form of autoimmune polyendocrine syndrome also known as Schmidt's syndrome,[1] or APS-II, is the most common form of the polyglandular failure syndromes.[2] It is heterogeneous and has not been linked to one gene. Rather, patients are at a higher risk when they carry a particular human leukocyte antigen genotype (DQ2, DQ8 and DRB1*0404). APS-II affects women to a greater degree than men (75% of cases occur in women).[2]
Features of this syndrome are:
- Addison's disease[3]
- Primary hypothyroidism
- Graves' disease
- Pernicious anaemia
- Primary hypogonadism (less common)
- Diabetes mellitus (type 1)
- Vitiligo (less common)
- Coeliac disease
- Myasthenia gravis
Symptoms
Symptoms of Addison's disease and Hashimoto's thyroiditis include:
- Dry hair
- Nausea
- Abdominal Pain
- Frequent urination
- Vomiting
- Weight and muscle loss
- Salt cravings / salt wasting
- Anorexia and cachexia
- High pulse / weakened heart
- Low blood pressure
- Weakness
- Hypoglycemia
- Numbness in extremities
- Migraines / dysparunia
- Poor immune system response
Some researchers favour splitting this syndrome into three distinct syndromes (numbering 2, 3[4] and 4), but evidence for these distinct combinations is not convincing.
Eponym
It is named for Hermann Adolf Alexander Schmidt (1831 – 1894), an Estonian / Baltic-German Physiologist.
