Drug Rash with Eosiniphilia and Systemic Symptoms
- Usually 2-8 weeks after drug exposure... patients may not think to tell you they started a “new” medication
- Most common culpits: anticonvulsants, allopurinol, sulfa drugs – but this list includes a wide range of drugs, so if the story fits and they have any new(ish) medication, have to consider
- Rash (anything from morbilliform, erythematous and scaly, to blisters and bulla), fever, lymphadenopathy. May also have facial edema.
- Eosinophilia – may OR MAY NOT be present
- Hepatic disfunction – most common associated organ dysfunction, varying patterns
- Renal dysfunction – proteinuria, hematuria, pyuria
- Can have associated myocarditis
- Incomplete presentations are common! “mini-dress” or “skirt syndrome”
- Patients may have myocarditis or other autoimmune disease years later
- Stop medication + systemic steroids + supportive care
