Toxic shock syndrome toxin-1 (TSST-1) antibody levels in burned children.

Young children with burns are at risk of developing a toxic shock-like illness during the first 2-3 days after the injury. The staphylococcal exotoxin, toxic-shock syndrome toxin-1 (TSST-1) is implicated in development of this illness. Low levels or absence of anti-TSST-1 antibodies may indicate susceptibility to this illness. Anti-TSST-1 antibody levels were measured in consecutive cases admitted to the children's burns unit. Results of antibody levels in 38 of the youngest children, aged 0.04-4.0 years are reported. At the time of admission to the unit 50% of the children had IgG antibodies to TSST-1. A higher number of young burned children had antibodies to TSST-1 than expected.
