Could a stomach infection worsen lupus? new study investigates
NCT ID NCT07157202
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This observational study will check if having an H. pylori stomach infection is linked to more active lupus in 115 adults. Researchers will use a stool test to detect the bacteria and a standard lupus score to measure disease activity. No treatments are given; the goal is simply to see if a connection exists.
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 a link is found, it could point toward managing lupus by treating H. pylori infections.
- What could go wrong
- This is an observational study, so it cannot prove cause and effect. The results may not lead to any treatment changes.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Eligible participants are adults (at least 18 years old) diagnosed with SLE according to ACR or SLICC criteria, who have not used antibiotics or proton pump inhibitors in the past four weeks, and provide written informed consent . Patients with prior gastric surgery, GI cancer, immunosuppressive therapy for non-SLE conditions, coexisting autoimmune diseases, pregnancy or lactation, or any current active infection other than H. pylori at enrollment are excluded . Of those eligible, the expected sample size is 115 patients, calculated to power the main outcome analysis. Demographic details (age, sex, ethnicity, disease duration, smoking status, and family history) and clinical manifestations (SLE-related symptoms, medications, and organ involvement) will be thoroughly documented to ensure a well-characterized, representative population .
