Methods: Eighteen neonatal intensive care unit (NICU) neonates with varicella exposure were given 1 ml/kg (43 International Units (IU)/kg) Varitect(r) IV-VZVIG. Serum VZVIG titers were assayed in neonatal recipients 0, 1, 7, 14, 21, 28, and 35 d after IV-VZVIG. Also, serum samples for VZV-IgM antibody determinations were obtained at 4 wk post-infusion. Results: No varicella developed in the 18 infants. Infusion of 1 ml/kg (43 IU/kg) IV-VZVIG was generally safe. The IV-VZVIG dose resulted in seroconversion of a non-immune newborn. Five infants had low basal VZVIG titers, and two of them had a 0.6-log10 increase at 24 h post-infusion. Neonatal VZVIG titers (mean ±SEM in log10) before IV-VZVIG and after by 1, 7, 14, 21, 28, and 35 d were 2.22 ±0.15, 2.17 ±0.17, 2.02 ±0.12, 0.87 ±0.2, 1.09 ±0.19, 2.33 ±0.07, and 2.16 ±0.1, respectively. Conclusions: One ml/kg (43 IU/kg) IV-VZVIG was generally safe. Our neonatal mean VZV-immune status did not significantly increase after the 1 ml/kg (43 IU/kg) IVVZVIG dose, although no varicella developed and it caused a VZV-specific seroconversion.展开更多
