Study Summary

Cephalosporin antibiotics are commonly used but can result in allergic reactions and anaphylaxis. There is no clear diagnostic approach for cephalosporin-allergic patients, and guidance for the use of other antibiotics in allergic patients is based on side chain chemical similarity and limited skin testing evidence. This project includes a clinical trial and mechanistic studies to optimize the approach to cephalosporin allergy and advance future diagnostics.

Primary Outcome

Placebo-controlled drug challenges will be used to confirm or disprove participant's cephalosporin allergies, and the proportion of included participants with confirmed allergies will be measured.

Interventions

  • DRUG Beta-lactam antibiotic (cefazolin, cefuroxime, cefotaxime, ceftazidime, ceftriaxone, cefepime, pre-pen, penicillin G, ampicillin, and histamine) double-blind skin testing
  • DRUG Culprit cephalosporin (cefazolin, ceftazidime, ceftriaxone, cefepime, cephalexin, cefaclor, cefadroxil, cefuroxime, cefpodoxime, cefdinir, or cefixime) double-blind placebo-controlled drug challenge
  • DRUG Similar cephalosporin (cefepime, ceftriaxone, cefaclor, cephalexin, cefixime, or cefdinir) antibiotic double-blind placebo-controlled drug challenge
  • DRUG Dissimilar cephalosporin (ceftriaxone or cefazolin) antibiotic double-blind placebo-controlled drug challenge
  • DRUG Amoxicillin double-blind placebo-controlled drug challenge
