Comparing short and long antibiotic courses for severe skin infections

Pilot Randomized Controlled Trial of Shorter Versus Extended Course of Antibiotic Therapy for Necrotizing Soft Tissue Infections

University of California, Irvine · NCT06002607

This study is testing whether a shorter 48-hour course of antibiotics is just as safe and effective as a longer 7-day course for patients with severe skin infections.

What this trial studies

This study evaluates the safety of a shorter course of antibiotics (48 hours) compared to a longer course (7 days) for patients with necrotizing soft tissue infections (NSTI) after achieving source control. It aims to determine if the shorter duration has similar risks of morbidity and mortality as the longer course. The study also seeks to correlate serum procalcitonin levels with the resolution of systemic infection in these patients. By potentially reducing antibiotic use, the study may help mitigate costs and adverse effects associated with prolonged antibiotic therapy.

Who should consider this trial

Good fit: Ideal candidates include adults 18 years and older presenting with symptoms of NSTI who require surgical intervention for source control.

Not a fit: Patients who are pregnant, prisoners, or unable to provide consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to safer and more effective antibiotic treatment protocols for patients with necrotizing soft tissue infections.

How similar studies have performed: Previous studies have shown promising results with shorter antibiotic durations in surgical infections, suggesting potential for success in this approach.
