Cyclic vomiting syndrome in children

Area of Science:

• Pediatric Gastroenterology
• Neurogastroenterology

Background:

• Cyclic vomiting syndrome (CVS) is characterized by severe, episodic vomiting lasting hours to days, interspersed with symptom-free periods.
• This condition significantly impacts children's quality of life, often necessitating emergency department visits for intravenous rehydration.
• The underlying gut-brain interaction in CVS is poorly understood, making diagnosis challenging.

Purpose of the Study:

• To review the current understanding of cyclic vomiting syndrome in children.
• To explore potential prophylactic treatments for pediatric CVS.
• To highlight the limitations in current evidence for pediatric treatment guidelines.

Main Methods:

• Literature review of cyclic vomiting syndrome.
• Analysis of diagnostic challenges and supportive care measures.
• Examination of prophylactic treatment options used in adults and their applicability to children.

Main Results:

• CVS presents with intense vomiting, lethargy, abdominal pain, anorexia, and nausea in children.
• Approximately 50% of affected children require intravenous rehydration.
• Supportive care includes hydration, rest, quiet environments, antiemetics, and sedatives.

Conclusions:

• While prophylactic treatments like amitriptyline and topiramate are considered for adults, robust pediatric data is lacking.
• Current evidence does not support specific prophylactic therapies for children with CVS.
• Further research is needed to establish effective preventive strategies for pediatric cyclic vomiting syndrome.
