Shigella flexneri bacteremia in a child

Area of Science:

• Pediatric Infectious Diseases
• Gastroenterology
• Critical Care Medicine

Background:

• Shigella flexneri is a significant cause of bacterial dysentery worldwide.
• Septicemia and severe gastrointestinal complications are rare but serious manifestations of Shigella infection.
• Necrotizing enterocolitis (NEC) is a critical condition primarily affecting neonates, but can occur in other pediatric populations.

Observation:

• An 8-year-old Saudi child with disabilities residing in a social home presented with symptoms of acute abdomen.
• Clinical examination revealed signs of severe toxic megacolon.
• The child was diagnosed with fulminant necrotizing enterocolitis.

Findings:

• The underlying cause of the severe gastrointestinal distress was identified as Shigella flexneri septicemia.
• The infection led to a rapidly progressing and lethal course of necrotizing enterocolitis.
• The case demonstrated an unusual and severe presentation of Shigella infection in a pediatric patient.

Implications:

• This case underscores the importance of considering Shigella septicemia in the differential diagnosis of acute abdomen and toxic megacolon in children, even in the absence of typical diarrheal symptoms.
• Early recognition and aggressive management are crucial for improving outcomes in severe Shigella infections.
• Further research into risk factors and optimal treatment strategies for severe Shigella-associated gastrointestinal complications in immunocompromised or vulnerable pediatric populations is warranted.
