Cure8 research brief
Colonic wash aspirates collected during routine colonoscopy may offer a practical way to detect asymptomatic C. difficile colonization in people with IBD, which could help researchers study how common colonization is and whether it affects disease or infection risk.
Adults with Crohn's disease or ulcerative colitis; gastroenterologists/endoscopists; researchers studying C. difficile, microbiome, or infection prevention in IBD.
The researchers enrolled 121 outpatient IBD patients (Crohn's and ulcerative colitis) undergoing colonoscopy and cultured colonic wash aspirates using selective media, with and without broth enrichment. Overall colonization was detected in 10.7% of participants; detection was higher when enrichment was used.
Crohn's patients had a higher colonization rate than UC in this cohort. Wash aspirates yielded enough DNA for sequencing at depths comparable to whole stool, suggesting they can be used for genomic and microbiome analyses.
The report does not identify clear clinical predictors of colonization and does not provide evidence that asymptomatic colonization leads to worse outcomes; it frames colonic wash sampling as a tool to study prevalence, persistence, and clinical significance rather than a validated clinical screening test.
This article reports an abstract-level clinical study demonstrating feasibility of detection and sequencing from colonoscopy wash samples. It does not provide evidence that screening alters outcomes, and no clinical predictors of colonization were found in this cohort.

The study will test whether routine point‑of‑care intestinal ultrasound changes clinical decisions compared with standard monitoring, which could make monitoring less invasive and more responsive if effective.
