Present state and future challenges in pediatric abdominal pain therapeutics research: Looking beyond the forest

Area of Science:

• Pediatric Gastroenterology
• Clinical Trial Design
• Pain Management

Background:

• Pediatric functional gastrointestinal disorders (FGIDs) with pain are difficult to treat using evidence-based methods.
• A significant lack of controlled studies and the complexity of FGID phenotypes hinder therapeutic trial design.
• Biopsychosocial factors and pharmacokinetic/pharmacodynamic considerations are often not adequately controlled in current trials.

Purpose of the Study:

• To review the challenges in designing therapeutic trials for pediatric functional abdominal pain.
• To discuss current pediatric abdominal pain therapeutics and future trial design considerations.

Main Methods:

• Literature review of challenges in defining entry criteria for pediatric FGID trials.
• Analysis of biopsychosocial factors impacting treatment outcomes.
• Examination of pharmacokinetic and pharmacodynamic factors in pediatric pain trials.
• Review of current therapeutic options for pediatric abdominal pain.

Main Results:

• Designing evidence-based trials for pediatric FGIDs is hampered by heterogeneity and lack of controlled studies.
• Biopsychosocial elements significantly influence treatment outcomes but are difficult to standardize in trials.
• Pharmacokinetic and pharmacodynamic data are crucial but often missing in pediatric pain research.

Conclusions:

• Improved trial design is essential for advancing evidence-based treatment of pediatric functional abdominal pain.
• Future research must address the complexity of FGID phenotypes and incorporate biopsychosocial and pharmacokinetic factors.
• Standardized approaches are needed to develop effective therapeutics for pediatric functional gastrointestinal disorders.
