Abstract

Some centers prefer CMV-IVIG over IVIG for the prophylaxis of EBV-related PTLD in solid organ transplant patients. Our objective was to compare the relative dose-related EBV ELISA antibody concentrations and cost of standard IVIG and CMV-IVIG. The concentration of EBV IgG to VCA was analyzed via ELISA in four lots of IVIG and four lots of CMV-IVIG. Relative EBV ELISA antibody concentrations and cost were compared assuming an IVIG dose of 0.5 gm/kg and CMV-IVIG dose of 0.15 gm/kg in a 50-kg patient. The price of IVIG was $70/gm and CMV-IVIG $430/gm. IVIG contains the same EBV antibody concentrations (20 790 ELISA antibody units/mL) than CMV-IVIG (17 430 ELISA antibody units/mL, p > 0.2) in the four lots of each product sampled. When factoring in the dosing scheme for a 50-kg patient, IVIG contains two times more EBV antibody than CMV-IVIG. Yet, CMV-IVIG is 1.8 times more expensive than IVIG ($3225 vs. $1750). In the four lots of each product sampled, IVIG contains more EBV antibodies and costs less than CMV-IVIG when factoring in the dosing scheme. Studies are needed to determine whether there is clinical efficacy of immunoglobulin products for EBV-related PTLD prophylaxis. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.
