  Autoimmune polyendocrine syndrome - Wikipedia, the free encyclopedia
Autoimmune dysfunction of the parathyroid gland (leading to hypocalcemia) and the adrenal gland (Addison's disease: hypoglycemia, hypotension and severe reactions in disease).
As opposed to type 2, this syndrome inherits in an autosomal recessive fashion and is due to a defect in AIRE ("autoimmune regulator"), a gene located on the 21st chromosome.
Autoimmune polyendocrine syndrome, type 2 (also known as "Schmidt's syndrome") is more heterogeneous, occurs more often and has not been linked to one gene.

In medicine, autoimmune polyendocrine syndromes are a heterogenous group of rare disease s characterised by autoimmune activity against more than one endocrine organ s, although non-endocrine organs can be affected.
As opposed to type 2, this syndrome inherits in an autosomal recessive fashion and is due to a defect in AIRE ("''a uto i mmune re gulator"), a gene located on the 21st chromosome.
POEMS syndrome - the ''E'' is for endocrinopathy; the cause is a paraprotein excreted by a plasmacytoma or multiple myeloma ; other features are polyneuropathy, organomegaly (hepatomegaly and splenomegaly), M-protein (paraprotein) and skin changes.

Autoimmune polyendocrine syndrome type I (APS I), a rare genetic disorder of childhood, has proven to be an invaluable tool in understanding autoimmune reactions.
APS I (OMIM 240300), also known as APECED (autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy), is a severe autosomal recessive disorder caused by mutations in the Aire gene on chromosome 21.
The disorder begins in early childhood and the patients gradually develop symptoms from autoimmune reactions in different endocrine and non-endocrine tissues and, in addition, mucocutaneous candidiasis, one of the hallmarks of the disease phenotype.

In a multicenter national study, we examined the relationship between the prevalence of autoimmune disorders in celiac disease and the duration of exposure to gluten.
In group A3, the prevalence of autoimmune disorders was significantly higher than in group C. In a logistic regression model, age at diagnosis was the only significant predictor variable of the odds of developing an autoimmune disorder (r = 0.3; P < 0.000001).
The incidence of CD in various autoimmune disorders is increased 10- to 30-fold in comparison to the general population, although in many cases CD is clinically asymptomatic or silent.

Autoimmunity is a condition where the body’s defenses turn on it’s own selves.
The process where the body learns to recognize self from non-self is called as clonal selection, that takes place in the thymus (an organ situated in the anterior part of the chest wall) in children.
The syndrome of multiple endocrine organ involvement (and other organs that don't have hormones, like the skin) is called by several names, including:

PGA syndrome type I (PGA-I), also known as autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) or Whitaker syndrome, is associated with candidiasis, hypoparathyroidism, and adrenal failure.
The evidence supporting the autoimmune etiology of this disease is based on the presence of chronic inflammatory infiltrates mainly composed of lymphocytes in the affected organs and on the presence of autoantibodies reacting to target tissue-specific antigens.
Their primary function is to differentiate autoimmune causes and infectious/iatrogenic causes of endocrine insufficiency.

[Autoimmune polyendocrine syndrome (APS)].Since Addison's pioneer observations in the 19th century, physicians have known that some individuals and their families may be affected by several spontaneous endocrine insufficiencies that are associated with autoimmune extra-endocrine processes.
APS-I or APECED syndrome appears in children firstly affected by recurrent muco-cutaneous candidiasis and hypoparathyroidism, followed by adrenocortical insufficiency and by other autoimmune processes.
APS-II is a more common syndrome characterized by adrenocortical insufficiency spontaneously occurring in non tuberculous adults and associated with autoimmune thyroiditis and/or type 1 diabetes.

Autoimmune polyendocrinopathy candidiasis ectodermal dystrophy (APECED), also known as autoimmune polyglandular syndrome Type I (APS1), is an autosomal recessive autoimmune disease caused by mutations in a gene designated as AIRE (autoimmune regulator).
Anderson MS, et al used aire- deficient mice to test the hypothesis that this transcription factor regulates autoimmunity by promoting the ectopic expression of peripheral tissue- restricted antigens in medullary epithelial cells of the thymus.
The mutant animals exhibited a defined profile of autoimmune diseases that depended on the absence of aire in stromal cells of the thymus.

 eMedicine - Polyglandular Autoimmune Syndrome, Type I : Article by Saleh A Aldasouqi
Depending on the presentation, liver function tests along with antibodies to the liver, kidney, and spleen (autoimmune hepatitis) may be considered because of their occasional association with PGA-I. Malabsorption and atrophic gastritis occasionally are associated with PGA-I, and patients with suggestive clinical features may require endoscopic biopsies to prove the diagnosis.
The educational aspect is extremely important because it helps the patient with the early detection of any new autoimmune states and aids in the adequate treatment of this chronic syndrome.
When evidence of a second autoimmunity is present, consider that the patient may have PGA-I or PGA-II because of the different prognoses in the syndromes.
