title: Hypercatabolism of the third component of complement (C3) in angioimmunoblastic lymphadenopathy.
abstract: A metabolic study with radioactively labelled C3 has been performed in a patient with angioimmunoblastic lymphadenopathy (AILD). The labelled protein was metabolized at a faster rate in the patient than in normal individuals. This indicates that the humoral immune system may be of pathogenetic significance in the AILD syndrome.
