PG - S59-64 LID - 10.1111/trf.13090 [doi] AB - BACKGROUND: Intravenous immunoglobulin (IVIG) is an efficacious treatment modality for a number of conditions and is usually well tolerated with few reports of serious adverse events; however, the administration of IVIG may occasionally result in clinically significant hemolysis. STUDY DESIGN AND METHODS: The literature was reviewed for case reports and case series of IVIG-associated hemolysis. The cases were scrutinized for clues as to the possible mechanism(s) of the hemolysis. RESULTS: Review of the 129 individual cases reported in the literature identifies clinical features shared by the majority of patients. These features included non-O blood group patients and treatment with high-dose IVIG as an immune-modulating agent for an underlying inflammatory or immune-mediated disorder. Other patient factors such as secretor phenotype, soluble ABH substance, and Fcgamma receptor polymorphisms may also play a role. CONCLUSIONS: It is known that high-dose IVIG given to non-O blood group patients with underlying inflammatory and/or immune-mediated disorders is associated with increased risk of hemolysis. This review reveals additional patient characteristics in cases of IVIG-associated hemolysis, including underrepresentation of D- and group B cases, higher incidence in pediatric Kawasaki disease and unique at-risk patient groups including allogeneic stem cell transplant recipients with group A donor in a group O recipient, and patients in whom soluble AB substance is removed by plasma exchange at the same time as receiving IVIG.
