This study reports a rare case of selective hypersensitivity to cefepime, a fourth-generation cephalosporin, in a 61-year-old male. Allergy testing confirmed cefepime as the sole trigger, with other beta-lactam antibiotics being well-tolerated.

Area of Science:

  • Clinical Immunology
  • Infectious Diseases
  • Pharmacology

Background:

  • Cefepime, a fourth-generation cephalosporin, exhibits broad-spectrum antimicrobial activity.
  • Cephalosporins are commonly used antibiotics, but hypersensitivity reactions can occur.

Observation:

  • A 61-year-old male experienced an immediate urticarial reaction following a single dose of cefepime.
  • Skin testing revealed positive reactions to cefepime but negative reactions to other beta-lactam antibiotics.

Findings:

  • This case represents the first documented instance of selective hypersensitivity to cefepime.
  • Subsequent challenge tests with amoxicillin-clavulanic acid and ceftazidime were tolerated, confirming selective allergy.

Implications:

Related Experiment Videos

  • Selective hypersensitivity to cefepime necessitates thorough allergological evaluation.
  • Complete allergy workups, including challenge tests, are crucial for patients with suspected beta-lactam antibiotic hypersensitivity.
  • This finding impacts antibiotic selection in patients with a history of cephalosporin reactions.
