Vancomycin-associated DRESS demonstrates delay in AST abnormalities.

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a severe cutaneous adverse drug eruption characterized by rash, fever, lymphadenopathy, hematologic abnormalities, and organ dysfunction. Identifying causative agents and monitoring disease course in DRESS syndrome is crucial to prevent end-organ damage. The temporal relationship between causative medications including vancomycin and laboratory abnormalities in DRESS has not been studied, limiting the utility of laboratory data in monitoring disease course. Our study aims to investigate associations between medication class and peak serum laboratory values using simple linear regression (absolute eosinophils, creatinine, alanine aminotransferase [ALT] and aspartate aminotransferase [AST]). We found a significant difference between timing of peak AST values among vancomycin-triggered DRESS compared to other trigger groups. These findings draw attention to the increased role of AST as a diagnostic and monitoring tool in DRESS.
