Popis: Abstract Drug reaction with eosinophilia and systemic symptoms (DRESS) is a rare severe cutaneous adverse drug reaction associated with multi-organ involvement and long-term sequelae. Human herpesviridae species reactivation has been observed, however, risk factors for reactivation and its impact on the clinical course and outcomes is unclear. We aimed to explore the impact of viral reactivation on DRESS on clinical outcomes and to identify potential risk factors for reactivation. This was a retrospective cohort study in an academic medical centre. Cases were validated in-hospital cases of DRESS from 2009 to 2017. Overall, 100 patients fulfilled the probable or definite DRESS case criteria. Ninety-three patients had at least one viral marker tested. Viral reactivation was positive in 39 patients (42%). HHV6, EBV and CMV reactivation occurred in 24 out of 85 cases (28%), 15 out of 87 (17%) cases, and 18 out of 89 (20%) cases respectively. Viral reactivation cases were associated with higher 1-year mortality, dialysis initiation, recurrent flares of disease, and longer hospital stay (all p
