[Hereditary angioneurotic edema. Clinical aspects, pathogenesis and therapy].

A family with hereditary angioedema is presented. In 4 members of the family the diagnosis was confirmed by decreased C1 esterase inhibitor levels. Clinical course and pathogenesis are described briefly. New ways of treatment are discussed, especially injection of purified C1 esterase inhibitor and stimulation of C1 esterase inhibitor synthesis by oral therapy with attenuated androgens.
