Small Intestinal Bacterial Overgrowth in Children with Short Bowel Syndrome: Risk Factors, Clinical Presentation and...

Area of Science:

• Pediatric Gastroenterology
• Intestinal Rehabilitation
• Microbiome Research

Background:

• Short bowel syndrome (SBS) in children presents with intestinal dysfunction, increasing the risk of small intestinal bacterial overgrowth (SIBO).
• Home parenteral nutrition (HPN) is often required for SBS management, but SIBO can complicate weaning from HPN.
• Understanding SIBO's impact on SBS patients is crucial for optimizing treatment outcomes.

Purpose of the Study:

• To describe the experience with SIBO in pediatric SBS patients on HPN.
• To identify risk factors, clinical presentations, and effective antibiotic treatments for SIBO in this cohort.
• To evaluate the impact of SIBO on the ability to wean from HPN.

Main Methods:

• A single-center retrospective descriptive cohort study.
• Inclusion of 16 children with SBS on HPN between January 2018 and December 2022.
• Analysis of clinically suspected SIBO episodes, focusing on risk factors, symptoms, and antibiotic interventions.

Main Results:

• Five children (31.2%) experienced SIBO episodes, with common symptoms including diarrhea (76%) and meteorism (56%).
• Antibiotic therapy varied, with 56% of episodes treated with one antibiotic type.
• Symptom resolution occurred in 56% after one antibiotic course; two children had refractory SIBO requiring cyclic regimens.

Conclusions:

• SIBO poses a significant challenge to weaning children with SBS off HPN.
• Early clinical suspicion is vital due to diagnostic test limitations.
• Individualized antibiotic strategies are necessary, considering patient-specific factors and recurrence risk.
