INTRAVENOUS IMMUNOGLOBULIN IN WOMEN WITH 5 OR MORE ABORTIONS

PROBLEM: Treatment for recurrent miscarriage has usually been given to all women with three or more abortions of unknown cause. As these pat ients have a 50-60% subsequent live birth rate, no treatment has been shown to unequivocally improve the live birth rate. Immunoglobulin is the latest treatment to be applied. In order to determine if immunoglo bulin improves the live birth rate, we analyzed the results of patient s expected to have a poor outcome in the subsequent pregnancy if left untreated, i.e., women with five or more abortions, who have aborted a fter paternal leucocyte immunization or who continue to abort despite possessing anti-paternal complement dependent antibody (APCA). METHODS : A preliminary trial was carried out using immunoglobulin (Sandoglobu lin, Sandoz, Switzerland). It was infused at a dose of 400mg/Kg body w eight, in the follicular phase of a cycle in which pregnancy was plann ed. A booster dose was administered as soon as pregnancy was diagnosed . RESULTS: Twelve patients were treated, ten conceived. Five have had subsequent live births. Two infants were premature but their size was appropriate for gestational age. The other three infants delivered at term. CONCLUSIONS: This is still too small a group from which to draw definite conclusions about the efficacy of immunoglobulin to prevent a bortion. However, five live births in ten patients is an encouraging r esult, especially when the expected poor obstetric outcome is consider ed. Hence the efficacy of immunoglobulin should be evaluated further i n high risk patients.
