Abstract
BACKGROUND: Toxic shock syndrome (TSS) is caused by Staphylococcus aureus infection. The disease entity manifests clinically as fever, hypotension, diffuse macular erythema that progresses to desquamation, and dysfunction of > 3 organ systems. Toxic shock-like syndrome (TSLS) has the same clinical manifestation as TSS but is caused by Streptococcus, usually group A, C or G. Here we report on a healthy woman who experienced group B Streptococcus (GBS)-related TSLS, possibly related to tampon use. CASE: A 37-year-old woman, gravida 1, para 1, met the diagnostic criteria for TSS/TSLS 5 days after her last tampon use. Blood, urine and vaginal cultures were positive only for GBS. Analysis of the blood isolate suggested a novel GBS superantigen. CONCLUSION: This is the second reported case of GBS causing tampon-associated TSS/TSLS. Up to 40% of healthy menstruating women are vaginally colonized with GBS. Superantigens elaborated by staphylococci and streptococci induce an immunologic mediator storm that affects the circulatory and end-organ systems to produce the clinical picture. Prompt medical therapy involves large-volume isotonic fluid resuscitation and antibiotic coverage with vancomycin and an antistaphylococcal beta-lactam. Clindamycin may dampen the immunologic response and endotoxin production. Corticosteroids and intravenous immunoglobulin may be useful adjuncts; however, nonsteroidal antiinflammatories should be avoided.
