Abstract
Eight different batches of intravenous immunoglobulin from 3 different manufacturers were tested for neutralizing activities against all currently known streptococcal superantigens. Statistically significant variation among different intravenous immunoglobulin preparations (P < .0001) and between individual streptococcal superantigens (P < .0001) was observed. These results might be helpful for optimizing the type and dose of intravenous immunoglobulin used in adjunctive therapy for severe invasive streptococcal disease.
