A case of neonatal toxic shock syndrome-like exanthematous disease concurrent with maternal toxic shock syndrome

Abstract

AbstractNeonatal toxic shock syndrome-like exanthematous disease (NTED) and toxic shock syndrome (TSS) are both caused by the bacterial superantigen, toxic shock syndrome toxin-1 (TSST-1), which is mainly produced by methicillin-resistantA 4-day-old full-term infant showed a typical clinical profile and laboratory findings that matched the criteria for the diagnosis of NTED, resulting in complete remission after 7 days. Fever and a skin rash were observed in the mother of the infant 3 days postpartum. In both cases, marked expansion and activation of Vβ2+ T cells in the peripheral blood was confirmed by flow cytometry. Anti-TSST-1 antibody was not detected in the mother nor in the infant.Obstetricians should consider TSS for the differential diagnosis of puerperal fever and systemic erythema if the infant develops NTED.
