Hidden gut inflammation may drive familial mediterranean fever
NCT ID NCT06981520
First seen Sep 15, 2026 · Last updated Sep 16, 2026 · Updated 1 time
Summary
Researchers are studying whether the lining of the small intestine shows signs of inflammation in people with Familial Mediterranean Fever (FMF), a genetic condition that causes recurring fevers and pain. The study compares intestinal biopsy samples from about 30 adults with FMF to samples from healthy controls. Using tissue staining, the team measures levels of three inflammatory proteins: IL-1, IL-18, and Caspase-1. The goal is to understand whether gut immune activity plays a role in FMF and whether these proteins could become targets for future treatments.
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 researchers find higher levels of these inflammatory markers in the gut lining of people with FMF, that could point toward new drug targets for the disease.
- What could go wrong
- This small study only measures markers in tissue samples. It cannot prove that gut inflammation causes FMF symptoms, and the findings may not lead to a treatment.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
This study includes adult patients diagnosed with Familial Mediterranean Fever (FMF) who underwent routine endoscopic evaluation with intestinal mucosal biopsies. A control group composed of age- and sex-matched individuals without inflammatory or autoimmune diseases was also included for comparative analysis. All participants were retrospectively selected based on availability of adequate tissue samples and relevant clinical data.
