Insights
This study investigated the gut microbiome in pediatric inflammatory bowel disease (IBD) families. Findings suggest maternal factors may influence the early-life microbiome, potentially impacting IBD development.
Area of Science:
- Microbiome research
- Pediatric gastroenterology
- Inflammatory Bowel Disease (IBD) etiology
Background:
- Pediatric inflammatory bowel disease (IBD) significantly impacts children's growth and quality of life.
- Early diagnosis and management are critical for pediatric IBD patients.
- This study examines the microbiome's role in treatment-naïve pediatric IBD and their families.
Purpose of the Study:
- To identify the role of the microbiome in the onset of pediatric IBD.
- To investigate microbial patterns within families affected by pediatric IBD.
- To explore potential microbial biomarkers for early IBD detection.
Main Methods:
- Recruited nine families with pediatric IBD (seven Crohn's disease, two ulcerative colitis) and healthy relatives.
- Collected fecal samples from pediatric IBD patients and family members.
- Utilized 16S ribosomal RNA gene sequencing and bioinformatics analysis.
Main Results:
- Identified dysbiosis patterns and specific microbial taxa associated with shared family traits.
- Observed the impact of IBD on distinct microbial taxa.
- Found that specific microbial taxa could serve as potential early detection biomarkers.
Conclusions:
- Maternal factors may play a role in shaping the early-life microbiome.
- These findings align with existing literature on IBD etiology.
- Understanding these factors has implications for IBD progression and management.
Background:
Pediatric inflammatory bowel disease (IBD) is a chronic inflammatory intestinal disease that affects both children and adolescents. Symptoms can significantly affect a child's growth, development, and quality of life, making early diagnosis and effective management crucial. This study focuses on treatment-naïve pediatric IBD patients and their immediate families to identify the role of the microbiome in disease onset.
Methods:
Nine families with pediatric IBD were recruited, comprising seven drug-naïve Crohn's disease (CD) patients and two drug-naïve ulcerative colitis (UC) patients, as well as twenty-four healthy siblings/parents. Fecal samples were collected for 16S ribosomal RNA gene sequencing and bioinformatics analysis.
Results:
We identified patterns of dysbiosis and hallmark microbial taxa among patients who shared ethnic, habitual, and dietary traits with themselves and their families. In addition, we examined the impact of the disease on specific microbial taxa and how these could serve as potential biomarkers for early detection.
Conclusions:
Our results suggest a potential role of maternal factors in the establishment and modulation of the early life microbiome, consistent with the current literature, which may have implications for understanding the etiology and progression of IBD.

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...

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...
