Menstrual Cup-Associated Toxic Shock Syndrome.

Toxic shock syndrome (TSS) is a rare inflammatory response syndrome associated with an infection by toxigenic strains of Staphylococcus aureus or group A β-haemolytic Streptococcus. We report a rare case of menstrual TSS associated with usage of a menstrual cup. The diagnosis was established through case definition criteria and supported by vaginal cultural growth of Staphylococcus aureus with evidence of TSS toxin 1 (TSST-1). The patient received prophylactic intravaginal clindamycin in an individual approach to reduce the risk of recurrence. No relapse was reported in the 12 months following discharge. LEARNING POINTS TSS should be considered in female patients presenting with fever, rash, hypotension and current menses. Prompt initiation of antibiotics and supportive care is critical.Menstrual cups may be a rare cause of TSS.Prophylactic antibiotic therapy may reduce the risk of relapse.
