Managing cyclic vomiting syndrome in children: beyond the guidelines

Area of Science:

• Pediatric Gastroenterology
• Neurology
• Pharmacology

Background:

• Cyclic vomiting syndrome (CVS) in children presents significant challenges, including frequent hospitalizations and reduced quality of life.
• Current treatment relies on empiric approaches, with initial guidance from the 2008 NASPGHAN Consensus Statement.
• Management encompasses lifestyle changes, medications, supplements, and stress reduction, organized by illness phases.

Purpose of the Study:

• To review current and emerging treatment strategies for pediatric cyclic vomiting syndrome.
• To highlight advancements in managing refractory and hospitalized pediatric patients with CVS.
• To emphasize personalized treatment approaches based on comorbidities and subphenotypes.

Main Methods:

• Review of recent literature and clinical experience with pediatric CVS management.
• Analysis of standard and novel prophylactic and abortive treatment strategies.
• Consideration of individualized therapies based on patient-specific factors like comorbidities and genotype.

Main Results:

• Established treatments include cyproheptadine and amitriptyline, with propranolol as a second-line agent.
• Novel prophylactic strategies involve NK1 antagonists and higher-dose amitriptyline.
• Hospital interventions include IV fluids, antiemetics, analgesics, and sedation for severe episodes.

Conclusions:

• While CVS management remains complex, recent advancements have improved outcomes for refractory and hospitalized children.
• Personalized treatment strategies, considering comorbidities and subphenotypes, are crucial for effective management.
• Ongoing research and accumulated experience are refining therapeutic approaches for pediatric CVS.
