Chronic persistent HHV‐6B infection after sulfasalazine‐induced DRESS with demonstration of HHV‐6 encoded small noncoding RNAs (sncRNAs) in Crohn’s‐like colitis: Case report

A sulfasalazine-induced DRESS (Drug Reactivation with Eosinophilia and Systemic Symptoms) was complicated by a Crohn's-like colitis. We demonstrated HHV-6 reactivation with presence of HHV-6 DNA and small noncoding RNA in colonic lesions. This observation confirms the major role of HHV-6 reactivation in DRESS manifestations and the importance of looking for HHV-6 reactivation in DRESS.
