Background
- T-cell mediated hypersensitivity reaction
Clinical Manifestations
- Characterized by fever, facial edema, maculopapular rash, lymphadenopathy, eosinophilia, atypical lymphocytosis, and multiorgan dysfunction
- Includes hepatitis, glomerulonephritis, arthritis, pneumonitis, and carditis
- Typical onset 2 to 8 weeks after starting medication
- Commonly-associated medications:
- Antibiotics, including vancomycin
- Vancomycin-associated DRESS is more common in European descendants, with the HLA-A*32:01 allele
- Antiepileptic medications
- Allopurinol
- Antibiotics, including vancomycin
- High mortality around 10%
DRESS Scoring System
- Developed for RegiSCAR, though I can't seem to find a primary reference
