Limited data exist on the effect of intravenous immunoglobulin (IVIg) on anti-HLA antibodies as determined by solid-phase assays. We reviewed our experience treating sensitized wait-listed kidney transplant recipients with IVIg as a method for desensitization and report our results utilizing Luminex single antigen (LSA) bead assay to quantify antibody reactivity (MFI). Fifteen patients with a cPRA > 40% received 2 g/kg IVIg per month for four months or until transplanted. LSA testing was performed before and after IVIg. Median MFI for anti-class I antibodies fell in 11 (73%) and increased in 4 (27%) patients after IVIg. Similar significant changes in MFI for anti-class II antibodies were observed in 10 patients (66%). Administration of IVIg was associated with a modest decrease in reactivity to both class I and II HLA antigens (median MFI change 493 and 1110, respectively; p < 0.0001) but did not significantly alter mean cPRA (85% before IVIg vs. 80% after IVIg; p = 0.1). Our data suggest a smaller effect of IVIg on HLA antibody reactivity than previously described, leading us to question how best to measure the efficacy of a desensitization protocol in current practice.
