title: Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) with Teicoplanin: A Case Report.
abstract: Intramuscular teicoplanin (400 mg every 12 h for three doses, then 400 mg daily, intramuscularly) was prescribed for a 37-year-old woman with presumptive diagnosis of cellulitis. On the 14th day of treatment, she developed generalized maculopapular rash, accompanied by fever, wheezing, shortening of breath, and lymphadenopathy. Lab tests revealed abnormal liver enzymes, leukocytosis, and eosinophilia. The treatment was interrupted with suspicion of drug reaction. Fever subsided after 48 h. Skin eruption and respiratory symptoms began to resolve within 2 weeks. The follow-up lab tests performed 1 month later indicated resolution of liver dysfunction. With respect to delayed onset of symptoms including fever, generalized rash, lymphadenopathy, and organ involvement, drug reaction with eosinophilia and systemic symptoms (DRESS) was highly suspected. The causality was evaluated by conventional scoring systems. The reaction was rated as probable (score = 5) according to RegiSCAR and possible (score = 5) based on Kardaun et al.'s scoring system. However, DRESS was not confirmed by the Japanese group's criteria for diagnosis of DRESS/drug-induced hypersensitivity syndrome (DIHS).
