Hidden STIs may mimic IBD in the gut, new study suggests
NCT ID NCT07061899
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is checking how many people with suspected hemorrhagic proctosigmoiditis (a type of bowel inflammation) actually have a sexually transmitted infection (STI) like chlamydia or gonorrhea. Researchers will take a swab during a routine colonoscopy from 214 patients across several hospitals in Denmark. If an STI is found, patients will be offered treatment. The goal is to find out how often STIs are the real cause of symptoms that look like inflammatory bowel disease.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this study could show that many cases of hemorrhagic proctosigmoiditis are actually caused by undiagnosed STIs, leading to better testing and treatment guidelines.
- What could go wrong
- This is an observational study with no new treatment being tested. It only measures how common STIs are in this group, so it won't directly change care. Results may not apply to other regions or populations.
