Vancomycin-induced Henoch-Schönlein purpura: a case report

Area of Science:

• Nephrology
• Rheumatology
• Dermatology

Background:

• Henoch-Schönlein purpura is a systemic vasculitis affecting small vessels.
• Its pathophysiology is not fully understood but is linked to hypersensitivity reactions.
• This case highlights a potential association between vancomycin and Henoch-Schönlein purpura.

Purpose of the Study:

• To report a case of vancomycin-induced Henoch-Schönlein purpura.
• To emphasize the importance of recognizing drug-induced vasculitis.
• To advocate for prompt discontinuation of causative agents like vancomycin.

Main Methods:

• A case report of a heart transplant recipient with an intra-abdominal abscess.
• The patient developed symptoms of Henoch-Schönlein purpura after vancomycin treatment.
• Diagnosis was confirmed by skin biopsy showing leucocytoclastic vasculitis with IgA deposits.

Main Results:

• The patient experienced two distinct episodes of Henoch-Schönlein purpura flares following vancomycin administration.
• Skin biopsy findings supported an allergic mechanism with IgA deposits and eosinophils.
• Discontinuation of vancomycin led to the resolution of symptoms without further recurrence.

Conclusions:

• Systemic vasculitis, including Henoch-Schönlein purpura, can be triggered by medications.
• Vancomycin, a commonly used antibiotic, should be considered a potential cause.
• Early recognition and cessation of vancomycin are vital for managing this rare but severe adverse event.
