[Acute infectious diarrhea in adults]

Area of Science:

• Gastroenterology
• Infectious Diseases
• Internal Medicine

Context:

• Acute infectious diarrhoea is a common condition with often suboptimal clinical management.
• Over-prescription of stool cultures and antibiotics is prevalent, contributing to inadequate care.
• Identifying patients at risk for severe complications is essential for appropriate treatment strategies.

Purpose:

• To highlight the importance of appropriate management strategies for acute infectious diarrhoea.
• To emphasize the need for early identification of high-risk patients and severe clinical presentations.
• To underscore the primary role of rehydration in treatment and the judicious use of antibiotics.

Summary:

• Acute infectious diarrhoea, while often self-limiting, requires careful management to avoid complications.
• Key management principles include prompt risk assessment for severe outcomes (e.g., dehydration, shock) in vulnerable populations (elderly, co-morbidities).
• Specific high-risk scenarios include food poisoning, E. coli O157:H7 infections, and Clostridium difficile colitis, necessitating targeted interventions. Rehydration with electrolytes and glucose is the cornerstone of treatment, with symptomatic treatments having limited value and antibiotics reserved for specific indications.

Impact:

• Improved clinical outcomes for patients with acute infectious diarrhoea through evidence-based management.
• Reduced antibiotic resistance and healthcare costs by curbing unnecessary prescriptions.
• Enhanced physician awareness regarding risk stratification and appropriate therapeutic interventions for infectious diarrhoea.
