Study procedure and patient allocation. DRESS cases were assigned to one of two groups: group 1: DRESS without proven drug sensitization and group 2: DRESS with proven drug sensitization to inducing drug. Frequency of drug-related relapses (subgroups a-c), skin tests and/or LTT to possibly involved drugs were evaluated in each group. Patients who were re-exposed to the triggering drug after the drug-related relapse resolution were identified
