Acute gastroenteritis in children : what role for antibacterials?

Area of Science:

• Pediatrics
• Infectious Diseases
• Pharmacology

Background:

• Acute gastroenteritis in children is frequently viral and self-limiting.
• Supportive care, including fluid, electrolyte, and nutritional management, is the cornerstone of treatment.
• Antibacterial therapy is an adjunct, not a primary treatment, for acute gastroenteritis.

Purpose of the Study:

• To define the role of antibacterials in treating acute gastroenteritis in children.
• To guide the selection and judicious use of antibiotics based on likely pathogens and clinical presentation.
• To highlight concerns regarding antibacterial resistance.

Main Methods:

• Review of current medical literature and clinical guidelines on the management of acute gastroenteritis in children.
• Analysis of indications for antibacterial use based on specific causative pathogens and disease severity.
• Discussion of risks, benefits, and the emergence of antibacterial resistance.

Main Results:

• Most childhood acute gastroenteritis cases are viral and require only supportive care.
• Antibacterial therapy is indicated for specific pathogens like Shigella and Vibrio cholera, and in severe cases of Salmonella, Yersinia, Aeromonas, Campylobacter, Plesiomonas, and Clostridium difficile.
• Antibacterial use should be avoided in enterohemorrhagic Escherichia coli infections, with empiric therapy considered only in severe cases with bloody diarrhea and stool leukocytes, especially in infants and the immunocompromised.

Conclusions:

• Antibacterial therapy for acute gastroenteritis in children should be restricted to specific bacterial pathogens and severe presentations.
• Careful consideration of benefits versus risks, including adverse drug reactions and the development of antibacterial resistance, is crucial.
• Judicious use of antibacterials is essential to preserve their efficacy and combat the growing threat of resistant strains.
