Initial gut microbiome characteristics linked to fecal calprotectin changes during exclusive enteral nutrition in children with Crohn's disease

Overview

This study explores the association between baseline gut microbiome features and fecal calprotectin (FCP) response during exclusive enteral nutrition (EEN) in pediatric Crohn's disease. Findings suggest that while certain microbiome changes correlate with biochemical responses, the estimates remain imprecise.

Background

Crohn's disease often presents in childhood, impacting growth and quality of life. Exclusive enteral nutrition is a first-line therapy that can improve clinical outcomes, yet responses vary among patients. Understanding the microbiome's role in treatment response is crucial for developing effective biomarkers and personalized therapies.

Data Highlights

No specific numerical data presented in the article.

Key Findings

• Baseline gut microbiome features showed exploratory associations with fecal calprotectin response.
• Several genera changed consistently during EEN treatment.
• Stool biochemical summaries indicated lower total amino acids and higher secondary bile-acid proportion post-treatment.
• The baseline model for predicting response had a mean area under the receiver operating characteristic curve of 0.655.
• External comparison revealed concordant directions in 7 of 12 overlapping genera.

Clinical Implications

Clinicians should consider the variability in microbiome responses when using EEN for pediatric Crohn's disease. Monitoring fecal calprotectin can provide insights into treatment efficacy and guide subsequent therapeutic decisions.

Conclusion

The study highlights the potential link between gut microbiome characteristics and fecal calprotectin response during EEN, although further research is needed to clarify these associations.
