Insights
Precision medicine for pediatric inflammatory bowel disease (IBD) is an unmet need. This review highlights the risks of overtreatment and undertreatment in children with IBD, emphasizing personalized care.
Area of Science:
- Pediatric Gastroenterology
- Inflammatory Bowel Disease (IBD) Research
- Precision Medicine in Pediatrics
Background:
- Therapeutic advances in pediatric inflammatory bowel disease (IBD) are improving care.
- Precision medicine, matching treatments to individual patients, is largely unfulfilled in IBD practice.
- Current risk-based management relies on generalized recommendations and imperfect predictors.
Purpose of the Study:
- To critically review current recommendations and evidence for pediatric IBD management.
- To identify and address the pitfalls of overtreatment and undertreatment in pediatric IBD.
- To underscore the unmet need for personalized treatment strategies in pediatric IBD.
Main Methods:
- Critical appraisal of existing literature and clinical guidelines.
- Focus on evidence related to overtreatment and undertreatment in pediatric IBD.
- Analysis of the limitations in current individualized treatment approaches.
Main Results:
- Overtreatment exposes children with mild IBD to unnecessary risks and adverse events.
- Undertreatment in high-risk pediatric IBD patients can lead to irreversible damage and poor outcomes.
- Lack of precise tools hinders individualized diagnosis and follow-up strategies.
Conclusions:
- Personalized medicine is crucial for optimizing pediatric IBD treatment.
- Avoiding both overtreatment and undertreatment is essential for improving long-term outcomes in pediatric IBD.
- Further research is needed to develop better predictors for tailored IBD management in children.
Abstract:
Despite major therapeutic advances in recent years, and early signs that the overall standard of care we can deliver to children with inflammatory bowel disease (IBD) is improving, the promise of precision medicine remains largely unfulfilled in daily practice. The goal is to match the right therapy to the right patient, in the right time window, so that treatment intensity reflects true disease biology and future risk rather than broad population averages. However, this approach is still an unmet need. Even when management is framed within a risk-based paradigm, clinical decisions are often guided by generalized recommendations and imperfect predictors, with limited capacity to individualize strategies at diagnosis and during follow-up. As a result, two opposite but equally relevant pitfalls remain very real. On one hand, overtreatment can lead to unnecessary exposure to immunosuppressive regimens in children and adolescents with mild, slowly progressive, or self-limited disease, increasing the burden of adverse events, monitoring, and psychosocial impact. On the other hand, undertreatment in truly high-risk patients can delay effective control of inflammation, allowing ongoing tissue damage, disease extension, growth impairment, and avoidable complications, ultimately worsening long-term outcomes. This critical review summarizes and critically appraises current recommendations and available evidence, focusing on the pitfalls of overtreatment and undertreatment in pediatric IBD.

A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
