Severe Haemolytic Disease of Foetus and Newborn due to Anti-c Alloimmunisation in a Multiparous Malay Woman: A case study

Abstract

Severe haemolytic disease of foetus and newborn (HDFN) is commonly caused by anti-D, anti-c and anti-K alloimmunisation. However, anti-c associated HDFN are infrequent because the majority of infants are relatively often c-negative. This case report describes a severe HDFN due to anti-c alloimmunisation in a multiparous Rhesus D positive mother. The baby was delivered prematurely at 32 weeks of gestation and unable to survive due to hydrops foetalis. Failure to detect anti-c alloimmunisation at the early antenatal period and unknown previous RBC alloimmunisation status were the main reasons for poorly suspicion of HDFN, which lead to improper foetal management and end up with foetal loss. Thus, routine antenatal RBC antibody screening during the early antenatal period is recommended for every pregnant woman with a history of HDFN or at risk for alloimmunisation for early detection and management of HDFN to prevent severe related morbidity or mortality.
