Our tagline, “Medicine moves fast“, is the absolute truth! Historically, identification of fetuses at risk of hemolytic disease of the fetus/newborn (HDFN) required amniocentesis for determination of the Delta OD450, Liley Curve. This was the first screen, which would then trigger cordocentesis for determination of the fetal hematocrit. We’ve now moved on to middle cerebral artery (MCA) doppler of the fetus for identification of those at risk. Additionally, we now have an ability to ascertain antigens on the fetal red blood cells through the maternal serum (cell free DNA). That’s amazing! Nonetheless, despite these wonderful advances, HDFN can still exist. But Medicine moves fast… In this episode, we will present brand new data from the NEJM. This Phase 2 international study, published on 8/7/24, describes the use of a monoclonal antibody (Nipocalimab) to block maternal IgG passage to the child. This is a revolution in HDFN prevention. Yep, medicine moves fast! Listen in for details.
