Streptococcal toxic shock syndrome with primary group A streptococcus peritonitis in a healthy female

Acute abdomen: a rare presentation of group a streptococcal infection

In this case report we describe a 38-year old female patient admitted to the emergency department with acute abdomen and sepsis. Broad-spectrum antibiotics were started. Abdominal imaging was inconclusive, exploratory laparoscopy showed four-quadrant peritonitis. No provoking factor could be withheld. Due to clinical deterioration the patient was transferred to the intensive care unit. Blood cultures showed the presence of group A streptococcus, and clindamycin was associated. She recovered, and could be discharged after several days. Peritonitis caused by group A Streptococcus pyogenes is rare in healthy individuals, and occurs mostly in middle-aged women. There is no consensus regarding surgical treatment but surgical exploration is often necessary to exclude secondary peritonitis. Treatment with broad-spectrum antibiotics and supportive measurements remain the cornerstone in patient management. Association of clindamycin has been shown to reduce mortality. There is inconclusive evidence to support Intravenous polyspecific immunoglobulin G (IVIG) therapy in streptococcal toxic shock syndrome.

Oral Sex following Abortion: Case Report of a Sexually Transmitted Infection of Group A Streptococcus Causing Peritonitis

Group A Streptococcus (GAS) is a rare cause of peritonitis with only a few reports of disease associated with surgical abortion, vaginal delivery, or intrauterine devices, most of which are speculated to be in association with the female genital tract. Only a single case of GAS infection transmission through contemporary oral sex has been previously reported. We report a strange case of GAS peritonitis occurring after abortion and oral sex.

Peritonitis caused by group A streptococcus: A case report and literature review

BACKGROUND

Group A streptococcus (GAS) occasionally causes life-threatening infections. We encountered a case of GAS peritonitis associated with bilateral salpingitis.

CASE PRESENTATION

A 56-year-old previously healthy woman suddenly experienced a fever of 40 °C and lower abdominal pain, and was taken to the emergency room. She exhibited a condition of severe sepsis with pan-peritonitis. Although an intra-peritoneal source of infection was not detected preoperatively, an exploratory laparotomy was performed at 3 h after her arrival. During the surgery, bilateral salpingitis was observed. Peritoneal drainage was performed. Meropenem was administered and she was extubated on the next day. GAS was detected in the vaginal fluid culture and ascitic fluid culture. Antibiotics therapy was completed on postoperative day 9 and the patient was discharged on day 10 without any complications.

METHODS

A literature review was performed using the following algorithm: "(group A streptococcus OR streptococcus pyogenes) AND (peritonitis)". All case reports and case series published in English after 1990 were reviewed.

RESULTS

Fifty-six reports including 65 cases were eligible. There was a strong sex difference, with 80% of cases being female. All patients had symptoms of peritonitis, 80% had high-grade fever, and 74% had shock. The average time from onset to start of treatment was 3.8 days. Abdominal surgeries were required in 80% of cases. Multiple organ failure developed in 23%, and the mortality rate was 4.6%.

DISCUSSION

GAS peritonitis is a rare but life-threatening disease. Emergency surgical exploration and drainage are required to prevent progression to multiple organ failure.

Group A Streptococcal Toxic Shock Syndrome after a Routine Gynecological Procedure

Streptococcal toxic shock syndrome (STSS) is a life-threatening illness mainly caused by invasive group A Streptococcus (GAS) infection. Herein, we report a case of a postmenopausal woman who developed STSS from an ascending vaginal GAS infection after cytocervical sampling. The patient complained of vaginal discharge, for which she underwent gynecological examination with vaginal sampling. The following day, there was onset of diarrhea and vomiting. After 7 days, she was admitted to our hospital with septic shock. Necrotizing enterocolitis was suspected and surgical intervention was performed; however, the patient was diagnosed with primary peritonitis and antibiotics were initiated. On day 2, GAS was suspected by blood cultures, and antibiotics were changed in consideration of STSS. On day 4, GAS was confirmed in blood, ascitic fluid, and vaginal swab specimens, and STSS caused by an ascending vaginal GAS infection was diagnosed. This case report indicates that STSS could occur following cytocervical sampling for vaginal discharge. If a woman has unexplained septic shock, especially with gastroenteritis symptoms, STSS should be considered as a differential diagnosis.
