Platelet-bound IgG in systemic lupus erythematosus with and without thrombocytopenia. 1981

J Mulshine, and F V Lucas, and J D Clough

A new assay for IgG bound to autologous platelets is described, in which IgG is dissociated from platelets washed at low pH, then measured by radioimmunoassay. Platelet-bound IgG was found to be elevated in thrombocytopenic patients with SLE and reduced in non-thrombocytopenic patients with this disease. There was a close inverse correlation of platelet-bound IgG and platelet count. Immune complexes did not interfere with the assay.

D008180	Lupus Erythematosus, Systemic	A chronic, relapsing, inflammatory, and often febrile multisystemic disorder of connective tissue, characterized principally by involvement of the skin, joints, kidneys, and serosal membranes. It is of unknown etiology, but is thought to represent a failure of the regulatory mechanisms of the autoimmune system. The disease is marked by a wide range of system dysfunctions, an elevated erythrocyte sedimentation rate, and the formation of LE cells in the blood or bone marrow.
