Fulminant necrotising enterocolitis associated with Clostridia
Insights
Necrotising enterocolitis (NEC) in infants is often linked to bacterial growth. Clostridia presence in NEC cases indicates a severe clinical course and higher mortality, especially with Clostridium perfringens.
Area of Science:
- Neonatal Medicine
- Pediatric Surgery
- Infectious Diseases
Background:
- Necrotising enterocolitis (NEC) is a serious gastrointestinal condition in infants.
- Bacterial infections are implicated in the pathogenesis and severity of NEC.
Observation:
- Infants with NEC and negative blood/peritoneal fluid cultures responded to medical management alone.
- 12 infants with positive cultures required surgical intervention.
- Among those requiring surgery, the presence of Clostridium species correlated with a more severe clinical course and higher mortality.
Findings:
- Five infants with negative cultures recovered with medical treatment only.
- Of 12 infants with positive cultures, 5 without Clostridium survived bowel resection with a mild course.
- Seven infants with Clostridium had severe NEC; 4 died, with Clostridium perfringens associated with fulminant disease, intestinal perforation, and death.
Implications:
- Clostridium species, especially Clostridium perfringens, are significant indicators of NEC severity and prognosis.
- Early identification of Clostridium in NEC cases may guide aggressive management strategies.
- Further research into targeted therapies against Clostridium in NEC is warranted.
Abstract:
5 infants with no growth of bacteria on cultures of blood and peritoneal fluid recovered from necrotising enterocolitis after medical treatment alone. 12 infants with positive cultures required surgery. 5 of these 12, who did not harbour clostridia, had a mild clinical course and all 5 survived segmental bowel resection. The 7 infants who harboured clostridia had a more severe clinical course and 4 died. In 3 of 4 infants with Clostridium perfringens, the necrotising enterocolitis was fulminant, characterised by severe pneumatosis intestinalis, extensive gangrene, early intestinal perforation, and a fatal outcome.
