DefinitionThis section has been translated automatically.
Differently defined disease group. Originally, the adjective "acquired" was used to refer to an "acquired C1-esterase inhibitor deficiency" and was thus used in contrast to hereditary angioedema (see below complement system). However, "acquired" angioedema in a broader sense also includes:
ClassificationThis section has been translated automatically.
- Type I (acquired angioedema, AAE I): partly with lymphoproliferative malignant diseases, e.g. malignant lymphomas.
- 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 reduction.
- Drug-induced, e.g. by ACE inhibitors, Ciclosporin A or other drugs (e.g. hawthorn extracts [Crataegutt] and others).
- Further described are 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).
ManifestationThis section has been translated automatically.
3.8% ofC1-esterase inhibitor deficiencies(angioedema) are acquired First manifestation in middle or old age (in contrast to hereditary angioedema), negative family history.
Clinical featuresThis section has been translated automatically.
Recurrent occurrence of cortisone- and antihistamine-insensitive angioedema over 48-72 hours. Abdominal symptoms and lethal course may occur. Associations with neoplasms such as lymphomas are also possible. Common occurrence of livedo racemosa and paraproteinemia without tumor detection and persistence during angioedema therapy are described in individual case reports. Regular check-ups to rule out lymphoma.
LaboratoryThis section has been translated automatically.
DecreasedC1q (typical of acquired forms); in addition to reduced C1 esterase inhibitor deficiency (protein concentration and enzymatic activity),C2,C4 and CH-50 are also reduced. During therapy normalization or increase to subnormal values of complement fractions.C4 can be seen as an indicator for a successful therapy.
