Background
- Known as DRESS syndrome
- A severe adverse drug reaction
- Usually begins within 8 weeks of starting a new drug
- 8-10% mortality
- Previously known as Dilantin Hypersensitivity Syndrome or Anti-convulsant hypersensitivity syndrome
- However, many other medications, particularly antibiotics
- A virus-drug interaction with HHV-6, HHV-7, EBV, and CMV may be a form of pathogenesis as well[1]
Associated Drugs
- Most common
- Phenytoin
- Phenobarbital
- Carbamazepine
- Allopurinol
- Sulfa drugs
- Others
- NSAIDS
- Anti-retrovirals
- ACE inhibitors
- Calcium-channel blockers
- Atypical antipsychotics (ziprasidone, olanzapine, etc.)[2]
- Other antibiotics
Clinical Features
- Fever and rash (varying; may resemble SJS) are typically first signs
- +/- lymphadenopathy
- Liver, kidney or hematologic system involvement
- Atypical lymphocytes, thrombocytopenia
- Despite name, eosinophilia only in ~30% of cases[citation needed]
Differential Diagnosis
- SJS/TENS
- Kawasaki Disease
- TTP
- See Rashes
Evaluation
- CBC with diff
- BMP
- LFTs
- Coags
- ESR
- CRP
- Viral hepatitis panel
- Biopsy
Management
- Discontinue suspected drug
- Supportive care: anti-pyretic, anti-puritic
- Systemic steroids in severe cases (controversial)
- Hepatitis, pneumonitis, extensive exfoliative dermatitis
- Family counseling as possible genetic component
Disposition
- Admit
