Imipenem-cilastatin-induced leukocytoclastic vasculitis

Area of Science:

• Pharmacology
• Dermatology
• Clinical Medicine

Background:

• Imipenem-cilastatin is a widely used antibiotic for treating serious infections.
• Maculopapular rash is a recognized adverse effect of imipenem-cilastatin therapy.
• Leukocytoclastic vasculitis is an inflammatory condition affecting small blood vessels.

Observation:

• A patient developed a maculopapular rash following administration of imipenem-cilastatin for a postoperative infection.
• The rash was diagnosed as leukocytoclastic vasculitis.

Findings:

• This case represents the first reported association between imipenem-cilastatin and leukocytoclastic vasculitis.
• Leukocytoclastic vasculitis has been previously linked to other medications including ciprofloxacin, zidovudine, piperazine, and lithium.

Implications:

• Clinicians should be aware of the potential for imipenem-cilastatin to induce leukocytoclastic vasculitis.
• This finding expands the spectrum of known adverse drug reactions associated with imipenem-cilastatin.
• Further investigation may be warranted to understand the mechanism underlying this rare adverse event.
