Drug Rash with Eosinophilia and Systemic Symptoms Syndrome Presenting After the Initiation of Staphylococcus hominis Infectious Endocarditis Treatment: A Case Report and Updated Review of Management Considerations

摘要

We present the case of a 62-year-old Caucasian man who was being treated for mitral valve endocarditis via a six-week course of vancomycin. On Day 32 of the treatment, he developed an erythematous, pruritic, desquamating, and painful rash covering 80% of the total body surface area and intermittent fevers. Laboratory findings included leukocytosis with peripheral blood eosinophilia and elevated erythrocyte sedimentation rate, C-reactive protein, and serum creatinine.Although the patient only completed five weeks of antibiotics, the decision was made to not complete the six-week antibiotic course due to suspicion of vancomycin-induced drug rash with eosinophilia and systemic symptoms (DRESS). The patient was then given 80 mg of intramuscular triamcinolone (Kenalog) and advised to apply topical 0.1% triamcinolone twice per day. At the three-month follow-up, the rash, leukocytosis, eosinophilia, and renal dysfunction had resolved. Clinicians must maintain a high index of suspicion for vancomycin-induced DRESS in patients with rash and eosinophilia for early recognition and treatment.DRESS syndrome treatment typically involves discontinuing the causative drug and promptly administering steroids. However, there is a therapeutic dilemma in administering steroids during the course of an active infection. Therefore, this article serves two purposes. First, this case report highlights our approach towards managing a patient with DRESS and concurrent infectious endocarditis. Second, we include a review of the management considerations when prescribing pulsed steroids so that clinicians have a single source as a practical guide towards reducing the potentially severe systemic sequelae in DRESS syndrome and its associated treatment.
