DefinitionThis section has been translated automatically.

Group of rare autoimmunological endocrinopathies characterized by immunological destruction and thus by insufficiency of endocrine organs. Depending on the organ manifestation, different clinical clinical pictures result.

ClassificationThis section has been translated automatically.

In the "autoimmunological endocrinopathies" 4 types of disease can be distinguished from each other:

  • APS type 1: Autoimmunologic polyglandular syndrome type 1 (syn: Chronic mucocutaneous candidiasis; juvenile form, called Schmidt syndrome or APECED ); autosomal recessive inheritance.
  • APS type 2: autoimmunologic polyglandular syndrome type 2 (adult form, Carpenter syndrome; APS).
  • APS type 3: is defined by autoimmunologic thyroid disease and another autoimmune disease, excluding Addison's disease (Betterle C et al. 2014).

  • APS type 4: is usually a diagnosis of exclusion. It includes 2 or more organ-specific autoimmune diseases that cannot be classified as APS types 1 to 3. Described are different combinations of: autoimmunological hypophysitis, vitiligo, primary immune thrombocytopenia, autoimmune gastritis or pernicious anemia.

  • Related syndromes /e.g. XPID

Occurrence/EpidemiologyThis section has been translated automatically.

Type 1 shows different prevalences in different ethnic groups (high prevalence among Iranian Jews and among Finns). In most European countries only sporadic occurrence.

Type 2 is much more common with 15-45 /1.0 million inhabitants.

EtiopathogenesisThis section has been translated automatically.

Type 1: Mutations in the autoimmune regulatory gene (AIRE - the AIRE gene - chromosome 21q22.3) are detected.

ManifestationThis section has been translated automatically.

Type 1: Childhood (APECED = Autoimmune Polyendocrinopathy-Candidiasis-Ectodermal Dystrophy Syndrome)

Type 2: Adulthood (3rd decade of life)

Clinical featuresThis section has been translated automatically.

APS type 1: Autoimmunologic polyglandular syndrome type 1 is characterized by:

  • Hypoparathyroidism (87%), chronic muco-cutaneous candidiasis (mostly before the age of 5), ectodermal dysplasias (dystrophy of the nails, gingival hyploasias, hypotrichosis, keratopathies) and adrenocortical insufficiency - Addison's disease - (69%). In addition, Hashimoto's thyroiditis, Graves' disease and ovarian insufficiency are less common.
  • Other symptoms:
    • Malabsorption syndrome (24% of APECED patients; steatorrhea, watery diarrhea).
    • Autoimmune hepatitis (10-20% of APECED patients). This can be asymptomatic and self-limiting, but can also be fulminant.
    • Diabetes mellitus (about 18% of APECED patients).
    • Hypogonadismue is found in 60%of female and in 14% of male APECED patients.

APS type 2: Autoimmunologic polyglandular syndrome type 2 (APS-2) occurs in families. The syndrome affects women>men (1.6 - 3x more often). First manifestation usually in adulthood.

The following predominant symptoms are found in type 2:

  • Addison's disease
  • Diabetes mellitus type 1
  • Hashimoto thyroiditis
  • Other symptoms include:
  • APS type 3: Autoimmune polyglandular syndrome type 3 consists of a rare association of autoimmune thyreopathy, diabetes mellitus type 1, autoimmune nephritis, ITP, SLE, myasthenia gravis, and other autoimmuneopathies. Dermatologically, lichen planus and autoimmune bullous diseases have been described.
  • APS type 4: Autoimmunologic polyglandular syndrome type 4 is a diagnosis of exclusion that includes 2 or > 2 organ-specific autoimmune diseases that cannot be classified as types 1 to 3. These include XPID syndrome and POEMS syndrome, among others.
