What this trial studies

This observational longitudinal study aims to collect wound exudate from twenty patients diagnosed with venous leg ulcers over a four-week period. Patients will undergo four study visits where wound exudate samples will be collected using various methods, including polyurethane foam and the NovaSwab technique. The study will also assess the wound bacteria microbiome and monitor wound size using advanced planimetric tools. Standard wound care will be provided, and a biobank will be established for future research with leftover samples.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 years with a confirmed diagnosis of venous leg ulcers meeting specific clinical criteria.

Not a fit: Patients with venous leg ulcers that communicate with bone or have known or suspected cancer in the wound may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of wound healing processes and improve treatment strategies for venous leg ulcers.

How similar studies have performed: While this study employs established methods, the specific focus on wound exudate in venous leg ulcers is relatively novel and may provide new insights.
