Two previously healthy women, aged 30 and 35 years, suffered pain in the lower abdomen, one before and the other after spontaneous delivery at 40 and 33 4/7 weeks of amenorrhoea, respectively, while a third woman, aged 33, at 36 weeks of amenorrhoea developed pain in the lower abdomen, fever, vomiting, and diarrhoea. All three women were found to have a uterine infection caused by streptococci of Lancefield group A (group A Streptococcus, GAS). In one woman, the diagnosis was made rapidly so that antibiotic treatment could be instituted in time; the other two developed sepsis and multiorgan failure, with a fatal issue in one of them. The three children also were septic, two recovered after treatment and one died. Since the eighties, serious GAS infection has been on the increase. The worst manifestation is the toxic shock syndrome caused by streptococci. Abdominal pains after delivery may be a first sign of this, and should not too readily be interpreted as just after pains. The condition may also develop before delivery. In view of the high mortality rate, early diagnosis and antibiotic treatment are of vital importance for mother and child.

Streptococcal toxic shock syndrome (STSS) is a systemic, life-threatening illness usually caused by invasive respiratory tract or skin and soft tissue infections of Streptococcus pyogenes (group A streptococcus, GAS). We report the case of an adult woman with lactational amenorrhea and GAS vulvovaginitis progressing to STSS. She was admitted to our hospital because of fever, lethargy, and a 2-week history of vaginal discharge; she also had hypotension and multiple organ failure. Blood and urine cultures yielded gram-positive cocci and GAS. After 14 days of antimicrobial therapy, she fully recovered without any complications. The vulvovaginitis was most likely the portal of entry for GAS, which is rarely recognized as a causative pathogen of vulvovaginitis. Lactational amenorrhea is thought to be a risk factor for GAS vulvovaginitis. It is important for clinicians to recognize the possibility of GAS vulvovaginitis in breastfeeding women with vaginal symptoms and consider the necessity of prompt antibiotic treatment.
