The association of anti‐P and early abortion

Abstract
The current report details the serologic findings in a case reported previously of a P1k woman, para 0 gravida 13, who was treated during her fourteenth pregnancy with plasmapheresis to reduce the anti-P-titer. These studies suggest that anti-P can induce early abortion in Pk women and that the abortions are immunologically mediated. Further, this case supports the disputed proposal that the anti-P component of anti-PP1Pk is responsible for pregnancy loss in p women.
