The maternal death rate remains unacceptably high worldwide, predominantly in areas of poor access to quality health services. According to the WHO, in 2017, 810 women died from preventable causes related to pregnancy and childbirth. Causes of maternal death are plenty, including previous morbidity and unexpected causes. Among the latter are infectious disease-related deaths. Herein, we describe a case of a 29-year-old woman at 37 weeks’ gestation who presented with right upper quadrant pain, which was initially considered to be pregnancy-related. However, she collapsed shortly after the hospital admission. The physical examination revealed severe hypovolemic shock due to a large amount of intraperitoneal free fluid. The patient was immediately rushed into an emergency cesarean section followed by exploratory laparotomy, which demonstrated a large intra-abdominal hemorrhage. The patient and her fetus died in the operating room. An autopsy revealed acute gangrenous cholecystitis along with abundant rod-shaped bacteria within the mucosa and vessels of the gallbladder, gas gangrene and rupture of the spleen, and signs of shock.

Clostridium perfringens (CP) was isolated in the culture of a splenic sample. Although CP is a well-known and dreadful infectious etiological agent, catastrophic cases still happen. The acquaintance of this infection by the caregivers is crucial for the early diagnosis and treatment. This is a quite unique way to provide a dismal chance of survival in sepsis cases by this agent.

An 80-year-old Japanese woman with diabetes mellitus was admitted with gastrointestinal symptoms and pyrexia. At presentation, liver abscesses and severe hemolytic anemia were noted. Before detailed diagnostic evaluation and adequate treatment, she suddenly died 2.5 hours after admission. The autopsy and bacteriological examinations revealed liver abscesses and massive intravascular hemolysis caused by Clostridium perfringens as well as other miscellaneous critical pathological findings, including acute renal tubular necrosis, lung edema, and pulmonary fat embolism. In this article, the detailed autopsy results are described and clinicopathologic characteristics on Clostridium perfringens-related sudden death are discussed with a review of the literature.

We report a case of Clostridium perfringens septicemia in a patient presenting with a bleeding ulcer of a jejunal interposition.

An 81-year-old female patient was acutely admitted to our hospital due to hematemesis and melena. She had a history of metastatic gastrointestinal stromal tumor, for which she was receiving second line treatment with sunitinib. She had also undergone a Merendino procedure 4 years prior to presentation. The patient underwent emergency gastroscopy, which revealed a bleeding ulcer in the jejunal interposition. Despite initial endoscopic control of the bleeding and transfusion of blood products, the hemoglobin level continued to drop, and the patient was treated for an assumed hemolytic transfusion reaction. The patient died 3 days following admission, and the results of blood cultures later confirmed a Clostridium perfringens septicemia. The postmortem examination revealed a diffuse spread of Clostridium perfringens to multiple organs.

This case is a reminder of the importance of considering septicemia, particularly in association with Clostridium perfringens, as a potential cause of hemolysis. It also demonstrates the extent of organ involvement in a case of diffuse clostridial myonecrosis.

We experienced a case of liver abscess due to Clostridium perfringens (CP) complicated with massive hemolysis and rapid death in an adequately controlled type 2 diabetic patient. The patient died 6 h after his first visit to the hospital. CP was later detected in a blood culture. We searched for case reports of CP septicemia and found 124 cases. Fifty patients survived, and 74 died. Of the 30 patients with liver abscess, only 3 cases survived following treatment with emergency surgical drainage. For the early detection of CP infection, detection of Gram-positive rods in the blood or drainage fluid is important. Spherocytes and ghost cells indicate intravascular hemolysis. The prognosis is very poor once massive hemolysis occurs. The major causative organisms of gas-forming liver abscess in diabetic patients are Klebsiella pneumoniae (K. pneumoniae) and Escherichia coli (E. coli). Although CP is relatively rare, the survival rate is very poor compared with those of K. pneumoniae and E. coli. Therefore, for every case that presents with a gas-forming liver abscess, the possibility of CP should be considered, and immediate aspiration of the abscess and Gram staining are important.
