Safer antibiotic choices for people with blood cancers and reported penicillin/beta‑lactam allergy

Optimizing antibiotic selection in hematologic malignancy patients with reported beta-lactam allergy

NIH-funded research University of Pennsylvania · NIH-11261247

This project helps people with blood cancers who report a penicillin or related antibiotic allergy learn whether they can safely use those drugs so they can get the most effective antibiotics.

What this research studies

If you have a blood cancer and are labeled as allergic to penicillin or other beta‑lactam antibiotics, this work will offer careful allergy evaluation including a detailed history, skin testing, and supervised oral challenge when appropriate. The goal is to remove incorrect allergy labels so you can receive preferred beta‑lactam antibiotics for infections. The team will follow participants' antibiotic choices, hospital length of stay, adverse events, and short‑term outcomes to see if delabeling improves care. Procedures are performed in a controlled clinical setting by allergy and infectious disease specialists.

Who could benefit from this research

Good fit: Ideal candidates are adults with hematologic malignancies who are hospitalized and report a penicillin or other beta‑lactam allergy.

Not a fit: Patients without a reported beta‑lactam allergy or those with a clear, recent life‑threatening anaphylactic reaction to beta‑lactams may not be eligible or benefit.

Why it matters

Potential benefit: If successful, more patients could safely use first‑line beta‑lactam antibiotics, which may reduce infection complications, decrease use of broader or more toxic drugs, and shorten hospital stays.

How similar studies have performed: Previous delabeling programs in general hospitalized patients have safely removed beta‑lactam allergy labels in 85–95% of cases and improved antibiotic selection, though this approach has been less studied specifically in people with blood cancers.
