title: The Seventh K Prathap Memorial Lecture. The pathogenesis of autoimmune immune complex disease.
abstract: It has been proposed that autoimmune immune complex disease, of which SLE is the type example, is caused essentially by a failure to properly metabolise immune complexes and that this allows the establishment of feedback cycles which cause more immune complexes to be formed. The essential genetic predisposition to this disease is complement deficiency of the components of the early classical pathway and some degree of genetic complement deficiency, particularly of C4a, is found in more than half the patients. It seems likely that acquired complement deficiencies, possibly present at the time of initiation of the disease, may be important in many of the other cases.
