Urobiome Analysis in Interstitial Cystitis/Bladder Pain Syndrome Reveals Nuanced Differences Associated with
The study found no widespread urobiome differences in interstitial cystitis/bladder pain syndrome (IC/BPS) patients based on pain localization. However, specific bacterial changes, like reduced Dialister, were linked to localized pelvic pain in IC/BPS.
Area of Science:
- Urology
- Microbiology
- Pain Medicine
Background:
- Interstitial cystitis/bladder pain syndrome (IC/BPS) is a common chronic pain condition affecting urinary function.
- IC/BPS symptoms vary, including localized pelvic pain or widespread pain, influencing treatment response.
- The role of bacteria in IC/BPS pathophysiology is not well understood.
Purpose of the Study:
- To investigate the association between the urinary microbiome (urobiome) and IC/BPS symptoms over time.
- To explore how pain localization phenotypes relate to urobiome composition.
- To analyze changes in bacterial diversity and stability in relation to IC/BPS symptoms.
Main Methods:
- Urine samples from a longitudinal randomized controlled trial of IC/BPS patients were analyzed.
- 16S rRNA sequencing was used to characterize the urobiome and bacterial taxonomy.
- Comparisons were made for urobiome diversity, stability, and associations with IC/BPS symptoms and pain localization.
Main Results:
- Menopausal status and recent urinary tract infections significantly influenced urobiome composition.
- No broad urobiome differences correlated with IC/BPS pain localization or severity were detected.
- A reduced abundance of a specific bacterial sequence (Dialister ASV) was observed in patients with localized pelvic pain.
Conclusions:
- This study provides insights into the urobiome's role in IC/BPS symptom presentation.
- Specific bacterial alterations may be associated with distinct IC/BPS pain phenotypes.
- Further research is warranted to explore the urobiome's impact on IC/BPS symptoms.
