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
- Usually urticarial, maculopapular eruption
- In some cases vesicles, bullae, pustules, purpura, target lesions, facial edema, cheilitis, erythroderma
- +/- lymphadenopathy
- Systemic involvement may manifest as hepatitis, pneumonitis, myocarditis, pericarditis, nephritis, colitis
- Atypical lymphocytes, thrombocytopenia, neutropenia, anemia
- Leukocytosis with eosinophilia in 50-90%, and mononucleosis in 40%[3][4]
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: antipyretic, anti-pruritic
- Fluid management as in burn
- Systemic steroids and/or cyclosporin/immunosuppressants in severe cases (controversial)
- Hepatitis, pneumonitis, extensive exfoliative dermatitis
- Other severe systemic manifestations
- Family counseling as possible genetic component
Disposition
- Admit
