Abstract
We report a patient with acute generalized exanthematous pustulosis (AGEP), which occurred 3 days after ingesting paracetamol and bromhexine. Both were immediately stopped and the rash resolved rapidly. To determine the offending drug responsible for AGEP, an in vitro drug-induced interferon (IFN)-γ release test was performed using an ELISA technique. Increased IFN-γ release was observed following in vitro challenge of the patient's lymphocytes with paracetamol or bromhexine (110% and 157% increase, respectively). In vitro challenge with paracetamol or bromhexine in a control patient, treated with paracetamol and bromhexine, did not induce an increase in IFN-γ. These findings suggest that the patient with AGEP may have polysensitivity to both drugs. The ELISA assessment also demonstrates the relevance of in vitro cytokine release tests in the investigation of such dermatoses. [ABSTRACT FROM AUTHOR]
