NIH-funded research R21 grant

Finding the best antibiotic treatment for certain bloodstream infections

Official title: Identifying Optimal Antibiotic Treatment for Non-CTX-M-Producing ESBL Bloodstream Infections

Funded at Johns Hopkins University · NIH-10991031 · Data updated 2026-11-12

This study is looking at how different kinds of enzymes in bacteria can change how well antibiotics work for people with bloodstream infections, so we can find the best treatment for each person and help them recover better.

Who could benefit from this research

Could help

Ideal candidates for this research are patients diagnosed with bloodstream infections caused by extended-spectrum β-lactamase-producing Enterobacterales.

Less likely to help

Patients with bloodstream infections not caused by ESBL-producing bacteria may not benefit from this research.

What this research studies

This research investigates how different types of extended-spectrum β-lactamase (ESBL) enzymes affect the effectiveness of antibiotic treatments for bloodstream infections. The study aims to identify the optimal antibiotic therapy based on the specific ESBL enzyme present in the bacteria, which could lead to more targeted and effective treatments. By analyzing patient outcomes and the types of ESBL enzymes, the researchers hope to improve treatment protocols and reduce mortality rates associated with these infections.

Why it matters

Potential benefit: If successful, this research could lead to more effective antibiotic treatments for patients suffering from bloodstream infections caused by ESBL-producing bacteria.

How similar studies have gone: Previous research has shown success in optimizing antibiotic treatments based on resistance mechanisms, indicating potential for this approach to improve outcomes for ESBL infections.
