Investigating gut microbiota in patients with limb lymphedema and recurrent infections

Official title: Typing of Gut Microbiota in Patients With Limb Lymphedema and Recurrent Lymphangitis, a Prospective Observational Study

Run by Fondazione Policlinico Universitario Agostino Gemelli IRCCS · NCT06228937 · Data updated 2026-11-12

This study looks at how the bacteria in the gut might be linked to limb lymphedema and repeated infections in patients to see if there are any important differences between those who have infections and those who don’t.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18-85 with upper or lower limb lymphedema and a history of recurrent soft tissue infections.

Probably not a fit

Patients with conditions such as diabetes, immunodeficiency, or those currently on antibiotic therapy may not benefit from this study.

What this trial studies

This observational study aims to explore the relationship between gut microbiota and limb lymphedema in patients who experience recurrent soft tissue infections. It will analyze stool samples from participants to identify pro-inflammatory changes in their microbiota. The study includes two groups: one with a history of infections and another without, both having lymphedema. By understanding these microbiota changes, the study seeks to shed light on potential underlying mechanisms of infection in lymphedema patients.

Why it matters

Potential benefit: If successful, this study could lead to new insights into managing recurrent infections in lymphedema patients, potentially improving their quality of life.

How similar studies have gone: While this approach is novel in the context of lymphedema, similar studies have shown promising results in understanding microbiota's role in other inflammatory conditions.
