Delayed hypersensitivity reaction to vancomycin
1Department of Critical Care Medicine, St. Vincent Hospital and University of Massachusetts Medical School, Worcester 01604, USA.
Abstract:
The use of vancomycin has increased dramatically in recent years with the emergence of methicillin-resistant Staphylococcus aureus and coagulase-negative staphylococci as important hospital pathogens. A patient receiving vancomycin 1.75 g intravenously as a single daily dose developed a syndrome characterized by high fever, erythema multiforme, eosinophilia, and presumed interstitial nephritis. This delayed hypersensitivity reaction resolved with discontinuation of the drug and treatment with methylprednisolone.
Insights
Vancomycin, a crucial antibiotic, can cause a rare delayed hypersensitivity reaction. This syndrome, including fever and rash, resolved after discontinuing vancomycin and using methylprednisolone.
Area of Science:
- Pharmacology
- Nephrology
- Infectious Diseases
Background:
- Vancomycin use has surged due to resistant bacteria like MRSA.
- Coagulase-negative staphylococci are significant hospital-acquired pathogens.
Observation:
- A patient on vancomycin developed fever, erythema multiforme, eosinophilia, and nephritis.
- This reaction occurred with a single daily intravenous dose of 1.75g.
Findings:
- The patient's symptoms indicated a delayed hypersensitivity reaction to vancomycin.
- Discontinuation of vancomycin and methylprednisolone treatment led to resolution.
Implications:
- Highlights the potential for vancomycin-induced hypersensitivity syndromes.
- Emphasizes the importance of recognizing and managing drug-induced nephritis.
- Suggests corticosteroids may be beneficial in treating this specific vancomycin reaction.
