Abstract

Background/objectives: The clinical characteristics and outcomes of hemolytic disease of the newborn (HDN) caused by irregular antibodies remain unclear. Herein, we analyzed the clinical features and prognosis of HDN.

Methods: Children admitted to our institution between June 2009 and December 2022 with a definite diagnosis of HDN were evaluated. Patients with irregular antibodies were matched in a 1:3 ratio to those with ABO incompatibility. Children with confirmed Rh-incompatibility hemolytic disease were divided into the RhD subgroup (hemolysis induced by Rh anti-D) and the non-RhD group (hemolysis induced by other Rh antibodies).

Results: The irregular antibody and ABO incompatibility group included 32 and 96 patients, respectively. Compared to the ABO incompatibility group, the irregular antibody group showed earlier jaundice; higher incidence of liver and spleen enlargement and anemia; higher direct antiglobulin test (DAT) positivity; earlier and more severe anemia; higher rates of enhanced phototherapy, blood transfusion, and blood exchange; and longer hospital stay (all < 0.05). Compared to the non-RhD group, the RhD subgroup showed an earlier occurrence of jaundice and a higher incidence of liver and spleen enlargement (both < 0.05). The multiple irregular antibody subgroup further showed earlier occurrence of jaundice and a higher rate of enhanced phototherapy, blood transfusion, and blood exchange than the single-antibody group (both < 0.05).

Conclusions: HDN caused by irregular red blood cell antibodies is rare, but clinical manifestations are serious. It is important to pay attention to the screening of irregular antibodies during pregnancy, to strengthen monitoring, and to provide intrauterine treatment and early intervention as necessary.
