Placenta-eluted gamma globulins (PEGG) have been recently and successfully used in the treatment of patients with rheumatoid arthritis. PEGG, eluted at acid pH from large pools of human placentas, contained 99% IgG material. Sephacryl S300 gel filtration revealed a main fraction (76%) of native IgG

Abstract
Patients who had active and severe rheumatoid arthritis (RA) were treated with human placentaโeluted gamma globulins (PEGG) composed of purified IgG eluted from trophoblastic cells. A control group of RA patients received retroplacental gamma globulins with no clinical effects. Seven of eleven treatments with PEGG showed good (4 patients) or very good (3 patients) clinical results. All patients had immunologic modifications demonstrated by a significant increase in active Eโrosetteโforming cells and mitogen responsiveness. The precise mechanism of immunomodulating effect of PEGG should be further investigated.
