Toxic shock syndrome in Infant/Neonate
Children are most susceptible to TSS between the ages of 6 months and 2 years. Before 6 months, the mother's antibodies are protective, and after age 2 years, the child begins producing antibody titers in higher amounts. TSS mortality rates are much lower in children than adults, at 5%-10% and 3%-5% for streptococcal versus staphylococcal types, respectively.
TSS may result from surgical wounds, burns, or any other type of mucous membrane, skin, or soft tissue infection with S aureus. If the US Centers for Disease Control (CDC) criteria are strictly followed, TSS is extremely rare in infants (refer to Diagnostic Pearls section for CDC definition of staphylococcal TSS). Partial expression may be due to passive immunity conferred by maternal antibodies during the first 3-6 months of life, the increased tolerance of infantile T cells to superantigens, and early treatment leading to a blunted course. Names for these partial expressions of toxin-mediated disease include neonatal toxic shock syndrome-like exanthematous disease (NTED) and staphylococcal toxemia.
