Neonatal lupus erythematosus with microvascular hemolysis

A female, term newborn born to a mother with a history of idiopathic thrombocytopenic purpura and antinuclear antibodies, single-stranded A antibody, and IgM anticardiolipin antibodies presented with immune thrombocytopenia, disseminated intravascular coagulation (DIC), microangiopathic hemolytic anemia, and a characteristic lupus rash in the periorbital areas. She responded to combined treatment with dexamethasone and intravenous immunoglobulin (IVIG). At age 9 months, she was readmitted with severe thrombocytopenia, DIC, and microangiopathic hemolytic anemia. She again responded to IVIG. This suggests that microangiopathic hemolysis can be a presenting symptom in neonatal lupus erythematosus and that reoccurrence of the microangiopathic hemolysis may occur even after the disappearance of lupus antibodies.
