title: Immune complexes in myasthenia gravis.
abstract: Complement components were measured and immune complexes were sought in 75 patients with myasthenia gravis. Thirty-four per cent had decreased concentrations of complement component C4, and 29% had circulating immune complexes. The greatest immunological abnormalities were found in patients with mild disease which supports recent immunoelectronmicroscopic findings.
