How clinically important are non-D Rh antibodies?

Abstract

Introduction: The advent of RhD immunoglobulin prophylaxis to prevent maternal RhD alloimmunization has reduced the incidence of this condition and its associated poor outcomes. Consequently, non-D Rh antibodies now account for a greater proportion of alloimmunized pregnancies. These antibodies have been the subject of comparatively little research. This study investigated the incidence and clinical outcome of pregnancies affected by non-D Rh alloimmunization at an Australian tertiary maternity service. Material and methods: This was a retrospective study of all pregnancies with non-D Rh antibodies (namely anti-C, -E, -c, -e, -Cw as well as the compound antibodies anti-CD, -cE and -ce) manag..
