DefinitionThis section has been translated automatically.
Differently defined group of diseases. Originally, the adjective "acquired" was used to refer to "acquired C1-esterase inhibitor deficiency" and thus was used in opposition to hereditary angioedema (see below complement system). However, "acquired" forms of angioedema in the broader sense also include:
- Histamine-mediated angioedema without C1-INH deficiency (often partial picture or equivalent of acute or chronic urticaria).
- Idiopathic angioedema without C1-INH deficiency
- Drug-induced angioedema without C1-INH deficiency (pharmacologically induced by drug inhibition of the renin-angiotensin system - ACE inhibitors/angiotensin II receptor blockers; they are bradykinin-mediated)
- Trauma-induced angioedema.
ClassificationThis section has been translated automatically.
Type I (acquired angioedema, AAE I): partly with lymphoproliferative malignancies, e.g. malignant lymphoma.
Type II (AAE II): like AAE I, detectable antibodies against C1-INH.

EtiopathogenesisThis section has been translated automatically.
Quantitative and/or functionalC1 esterase inhibitor deficiency. Pronounced C1q deficiency.
Drug-induced, e.g., by ACE inhibitors, ciclosporin A, or other drugs (e.g., hawthorn extracts [Crataegutt] and others).
Furthermore, the formation of antibodies against the active site of theC1 inhibitor as well as the activation of the complement cascade by anti-idiotypic antibodies with excessive consumption (AAE type II) are described.
