Trirnethoprim-Sulfamethoxazole-Induced Drug Eruption With Eosinophilia and Systemic Symptoms (DRESS)

摘要

Drug rash with eosinophilia and systemic symptoms (DRESS) is a severe and potentially life threatening adverse drug reaction. To help identify DRESS, several criteria have been established; however, there is still a lack of consensus on diagnosis, and clinical judgment is paramount. Here we describe a 24-year-old female who presented with a cutaneous eruption, fever, lymphadenopathy, eosinophilia, facial edema, and elevated liver enzymes four and a half weeks after a 10-day course of Trimethoprim/ sulfamethoxazole (TMP/SMX). We used both the RegiSCAR and J-SCAR criteria to show the validity of classifying this case as DRESS, we also comment on the only other three cases, published to date, that had been reported as TMP/SMX induced DRESS. DRESS can be a difficult diagnosis due to its diverse symptomatology and delayed presentation therefore, high suspicion and exclusion of other causes is key. Use of validated diagnostic criteria can aid the clinician in this regard. In the absence of a well-established therapy, early recognition, withdrawal of suspected drug(s), and supportive care play a crucial role in the management of DRESS.
