Non RhD isoimmunization causing severe hemolytic disease of fetus and newborn in Rh positive pregnancies: report of 2 cases with review of literature

Geetika Sharma, Sangeeta Pahuja, Deeksha Singh, Ramvilash ., Manisha .


Anti D immunoprophylaxis widespread use in antenatal patients has led to dramatic reduction in the rates of alloimmunization due to anti D, which is the most common Rh antibody causing severe Hemolytic Disease of Fetus and New born (HDFN). However, there has been increase in the rates of non Rh D antibodies causing alloimmunization in pregnant women and leading to moderate to severe HDFN. We hereby report two cases of neonates presenting with moderate to severe HDFN with strongly positive DAT due to Rh anti-c antibody in Rh-positive mothers. Thus, antenatal antibody screening should be done in all Rh-positive pregnant women to prevent the diagnostic delay of HDFN occurring due to Non anti-D isoimmunization in the fetus.
