Acute gastroenteritis: from guidelines to real life.

Area of Science:

• Gastroenterology
• Pediatrics
• Infectious Diseases

Background:

• Acute gastroenteritis is a prevalent condition with significant global health and economic impacts.
• Viral infections, particularly rotavirus, are primary causes of acute gastroenteritis in children.
• Oral rehydration therapy (ORT) is a recommended first-line treatment for mild to moderate dehydration, yet its use is suboptimal.

Purpose of the Study:

• To evaluate the role of antiemetics in improving ORT adherence and reducing healthcare utilization in acute gastroenteritis.
• To assess the efficacy of ondansetron in managing vomiting associated with acute gastroenteritis.
• To inform updated clinical guidelines on the use of antiemetics in conjunction with ORT.

Main Methods:

• Review of recent studies investigating the use of antiemetics, specifically ondansetron, in pediatric acute gastroenteritis.
• Analysis of data on ORT compliance, vomiting frequency, and hospitalization rates in patients receiving ondansetron.
• Synthesis of evidence to support guideline revisions.

Main Results:

• Ondansetron has demonstrated efficacy in reducing vomiting, thereby enhancing patient tolerance and compliance with ORT.
• The use of ondansetron has been associated with a decreased rate of hospitalization for acute gastroenteritis.
• Recent evidence supports a revised recommendation for antiemetic use in specific scenarios of acute gastroenteritis.

Conclusions:

• Antiemetics, particularly ondansetron, can be a valuable adjunct to ORT in managing acute gastroenteritis, especially when vomiting is a barrier to treatment.
• Improved ORT compliance facilitated by antiemetics can lead to reduced hospital admissions.
• Clinical practice guidelines are evolving to incorporate the benefits of antiemetics in acute gastroenteritis management.
